Detailed Description
The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.
Example (b): as shown in fig. 1, 2, 3, 4 and 5, an improved twisted frame device for high-precision cables comprises abottom plate 11, a framevertical plate 12 and acore wire opening 13, and further comprises a fixed wheel unit 1, amovable wheel unit 2, alimiting rod unit 3 and a spring jacking unit 4, wherein the fixed wheel unit 1 is arranged at two side positions in thecore wire opening 13 and used for clamping acable core wire 14, the limitingrod unit 3 is arranged on the fixed wheel unit 1 and jacks themovable wheel unit 2 through supporting so as to limit the minimum clamping width of thecable core wire 14, and the spring jacking unit 4 is arranged on the core wire opening 13 and pushes themovable wheel unit 2 through elasticity so as to regulate the clamping force of themovable wheel unit 2 on thecable core wire 14.
In this embodiment, the number of thecore wire openings 13 is 4, and after the position is selected according to the twisting mode of the cable, thecable core wires 14 can only be pulled axially by the clamping action of the fixed wheel unit 1 and themovable wheel unit 2, so that the shaking is reduced as much as possible, and the multiplecable core wires 14 can only be twisted into one cable stably and efficiently, wherein thelimiting rod unit 3 and the spring jacking unit 4 are used for ensuring the stable and proper clamping action.
Wherein, gaglever post unit 3 has the effect of jack-up width size adjustable, spring jack-up unit 4 has the effect of holding down intensity size adjustable simultaneously, consequently tocable conductor 14 has following four kinds of modes: the thick wires are tightly pressed, the thick wires are tightly pressed in a small width, the thin wires are tightly pressed in a large width, and the thin wires are tightly pressed in a small width, so that all stranding requirements can be met, and the inconvenience that stranding equipment on the market can only tightly press the thick wires and tightly press the thin wires in a small width is avoided.
The fixed wheel unit 1 comprises afixed shaft 101 and a first arc-shapedconcave wheel 102, wherein two ends of thefixed shaft 101 are arranged on the inner side surface of the core wire opening 13, and the first arc-shapedconcave wheel 102 is sleeved on thefixed shaft 101 and is axially limited;activity wheel unit 2 is including setting up respectively twomounting grooves 201 on 13 medial surfaces of heart yearn are in the setting spacingpost 202 on themounting groove 201,loose axle 203 sets uploose axle 203 both ends and with theaxis body hole 204 that spacingpost 202 cup jointed to and cup joint the setting and be in on theloose axle 203 and the spacing second arcconcave wheel 205 of axial. The limitingrod unit 3 comprises afixed rod 301 with an opening at one end and sleeved on thefixed shaft 101, a fasteningbolt 302 arranged on the sleeved hole of thefixed rod 301, aninternal thread cover 303 arranged on the movable end of thefixed rod 301 in a screwed mode, amovable rod 304, aninstallation groove 305 arranged at one end of themovable rod 304 and used for being sleeved with theinternal thread cover 303, and aradial notch 306 arranged at the other end of themovable rod 304 and used for clamping and supporting themovable shaft 203.
In this embodiment, thecable conductor 14 is pulled in the middle of the arc-shaped groove between the first arc-shapedconcave wheel 102 and the second arc-shapedconcave wheel 205, and theinternal thread cover 303 is rotatably adjusted on thefixing rod 301, for example, when thecable core 14 is not pressed, the diameter is 1.0mm, at this time, if a relatively large clamping and limiting effect is required, theinternal thread cover 303 is rotated to adjust the position of themovable shaft 203, the distance between the middle parts of the first arc-shapedconcave wheel 102 and the second arc-shapedconcave wheel 205 is 0.8mm, and if a relatively small clamping and limiting effect is needed, the distance is adjusted to be 0.9mm, therefore, the first arc-shapedconcave wheel 102 and the second arc-shapedconcave wheel 205 have four overall pressing and clamping limit modes of 'thick wire large-force pressing, thick wire small-width pressing, thin wire large-force pressing and thin wire small-width pressing' on thecable core 14.
It is important to note that the distance between the first arc-shapedconcave wheel 102 and the second arc-shapedconcave wheel 205 is the maximum value of the clamping and clamping force on thecable core 14, that is, the spring jacking unit 4 presses themovable shaft 203 against the innermost side of theradial notch 306, which is the maximum value, and the progress of the clamping force is determined by the spring jacking unit 4.
The number of thelimiting rod units 3 is two, and the two limiting rod units are respectively arranged on thefixed shaft 101 and located at two sides of the first arc-shapedconcave wheel 102.
Spring jack-up unit 4 sets up including cup jointingspacing post 202 is last and be in keeping away from ofmounting groove 201 elasticity jack-up on the side of tight pulley unit 1 the jack-upspring 401 ofloose axle 203 sets up on themounting groove 201 medial surface and the interlude with the parallelU type post 402 ofspacing post 202 to and cup joint and the axial fixity compress tightly through the increase and decrease regulation on the interlude ofU type post 402 the mode of jack-upspring 401 number of turns is in order to be used for adjusting jack-upspring 401 is right thespacing ring 403 of elastic force is effectively promoted toloose axle 203. Thelimit ring 403 is a circular ring provided with anarcuate notch 404 for the jackingspring 401 to radially extend and retract. The spring jacking unit 4 further comprises an in-groove limiting opening 405 which is arranged on the inner side surface of themounting groove 201 and used for axially limiting and fixing the limitingring 403.
In this embodiment, according to the specific diameter of thecable core 14, theinternal thread cover 303 is rotatably adjusted until the distance between the first arc-shapedconcave wheel 102 and the second arc-shapedconcave wheel 205 is, for example, 70-90% of the core diameter, at this time, the specific clamping pressure of the second arc-shapedconcave wheel 205 on thecable core 14 is based on the number of times of theunclamped jacking spring 401 that is "paid out" by theretainer ring 403, that is, when the actual clamping pressure is higher, theretainer ring 403 is first rotated until thearcuate notch 404 is located below, and thejacking spring 401 passes through thearcuate notch 404 and abuts against themovable shaft 203 for a larger number of times, that is, an effective spring force generation part, at this time, theretainer ring 403 is then rotated until thearcuate notch 404 is far away from, separated from thejacking spring 401, and thejacking spring 401 is clamped by theretainer ring 403, namely, the area of the invalid jackingspring 401 and the area of thevalid jacking spring 401 can be effectively separated, wherein thelimiting ring 403 is clamped by the in-groove limiting opening 405, so that thelimiting ring 403 can not slide and stably limit and fix the jackingspring 401, and the invalid and valid parts of the jackingspring 401 are distinguished.
The first arc-shapedconcave wheel 102 and the second arc-shapedconcave wheel 205 are axially limited by angular contact bearings. Theradial slot 306 has a slot width equal to the diameter of themovable shaft 203. Thefixed shaft 101 and themovable shaft 203 are parallel to each other.
In the present embodiment, the angular contact bearing is used in the conventional axial fixing structure.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various modifications can be made within the knowledge of those skilled in the art without departing from the gist of the present invention. These are non-inventive modifications, which are intended to be protected by patent laws within the scope of the claims appended hereto.
