Description

Protection device of electromagnetic chuck

Technical Field

The utility model particularly relates to an electromagnet's protector.

Background

The electromagnetic chuck is characterized in that an internal coil is electrified to generate magnetic force by utilizing an electromagnetic principle, a workpiece contacting the surface of a panel is tightly attracted by a magnetic conduction panel to fix the processed workpiece, and when the workpiece needs to be taken down, the magnetic force disappears as long as the coil is powered off, and the workpiece is naturally put down. The existing electromagnetic chuck is composed of an iron core, a coil, a panel and a bracket, and has no any protective measures. If the work piece, especially the tubular member of great volume takes place the outage suddenly in the transportation, can lead to the work piece to take place unexpected the falling, causes the incident. Therefore, it is necessary to provide the existing electromagnetic chucks with a corresponding protection mechanism to cope with such a problem.

Disclosure of Invention

In view of this, the utility model provides a problem to prior art exists, provides an electromagnetic chuck's protector. The technical scheme of the utility model is that:

the utility model provides an electromagnetic chuck's protector, includes the support, be equipped with electromagnetic chuck on the support, still be equipped with two lift cylinders on the support, two lift cylinders use electromagnetic chuck sets up in its both sides as the symmetry, the telescopic link is connected to the lift cylinder, the base is connected to the telescopic link bottom, be equipped with die clamping cylinder and clamping jaw on the base, and die clamping cylinder connects the clamping jaw, the lift cylinder with die clamping cylinder all links to each other with the battery, the battery is fixed on the support.

Preferably, the clamping jaw is of a double-jaw structure, and each jaw is of a fold line-shaped structure with an angle of 120-150 degrees.

Preferably, the clamping jaw is sleeved with an anti-slip plastic layer.

Optionally, the protection device further comprises a PLC controller, the PLC controller is respectively connected with the lifting cylinder and the clamping cylinder, and the PLC controller is connected with the storage battery.

The technical effects of the utility model are that: the utility model discloses simple structure, reasonable in design further fixes the pipe fitting through setting up lift fixture on the support, in case electromagnet takes place the outage, the battery can continue to guarantee lift fixture work to guarantee that the key can not take place to fall, can effectively prevent that the incident from taking place.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings and specific examples, which are given by way of illustration and not of limitation.

As shown in fig. 1 and 2, the utility model provides a protection device's of electromagnetic chuck structural sketch map, includingsupport 1, be equipped withelectromagnetic chuck 2 on thesupport 1, electromagnetic chuck's structure is as shown in fig. 3, includingdisk 10,shield 11,coil 12,shell body 13.

Still be equipped with twolift cylinders 3 onsupport 1, twolift cylinders 3 withelectromagnet 2 sets up in its both sides as the symmetry,lift cylinder 3 connectstelescopic link 4,base 14 is connected to 4 bottoms of telescopic link, be equipped with dieclamping cylinder 5 and clampingjaw 6 on thebase 14, and dieclamping cylinder 5 connectsclamping jaw 6,lift cylinder 3 with dieclamping cylinder 5 all links to each other withbattery 7,battery 7 is fixed onsupport 1.

Theclamping jaw 6 is of a double-jaw structure, each jaw is of a fold line-shaped structure with an angle of 120-150 degrees, the double-jaw structure can facilitate the sleeving of a pipe fitting, and when the clamping jaw is clamped tightly, the fold line-shaped structure with the angle of 120-150 degrees can ensure that the stress of each jaw is as small as possible. In order to better fix the pipe, theclamping jaw 6 is sleeved with an anti-slipplastic layer 8, and the anti-slip plastic layer can also reduce the abrasion of the pipe to the clamping jaw.

In this embodiment, for bettercontrol lift cylinder 3 and dieclamping cylinder 5, protector still includesPLC controller 9,PLC controller 9 respectively withlift cylinder 3 with dieclamping cylinder 5 is connected, through controlling the PLC controller realizes the centre gripping of lift clamping mechanism to the pipe fitting,PLC controller 9 connectsbattery 7.

The utility model discloses when using, earlier through PLC controller control lift cylinder, with the clamping jaw descend to with electromagnet wait high, make the clamping jaw aim at the pipe fitting that will fix, treat that the pipe fitting adsorbs back on electromagnet, start die clamping cylinder through the PLC controller, the clamping jaw tightens up and cliies the pipe fitting.

The utility model discloses simple structure, reasonable in design further fixes the pipe fitting through setting up lift fixture on the support, in case electromagnet takes place the outage, the battery can continue to guarantee lift fixture work to guarantee that the key can not take place to fall, can effectively prevent that the incident from taking place.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
