具体实施方式detailed description
下面结合附图对本发明做进一步详细说明。The present invention will be described in further detail below in conjunction with the accompanying drawings.
如图1、图2所示：支架1靠两个肋板支撑整个装置，支架1靠螺栓3、螺母4、垫圈5联接到工作台22上，底座2靠螺钉8联接到支架1上，整个过程靠螺杆6的旋紧旋出，螺杆6上设置有开口销17，来实现对顶杆11的压紧和松开，微量调整进行定位夹紧。As shown in Figure 1 and Figure 2: the bracket 1 supports the entire device by two ribs, the bracket 1 is connected to the workbench 22 by bolts 3, nuts 4, and washers 5, the base 2 is connected to the bracket 1 by screws 8, and the whole The process depends on the tightening and unscrewing of the screw rod 6, and the screw rod 6 is provided with a cotter pin 17 to realize the compression and loosening of the ejector rod 11, and micro-adjustment for positioning and clamping.
所述的螺杆6可以在底座2内左、右活动。The screw rod 6 can move left and right in the base 2 .
采用螺钉14限定横挡板一13与横挡板二15，对夹具小车在横向进行限制与定位；采用侧挡板12对夹具底盘19进行侧向的导向和定位，保证水平方向的定位精度。螺杆6向右进给，给压板10一个向右的力，压板10采用周向大尺寸，比顶杆11的截面尺寸的大一点，能够均匀受力，不至于在周向跳动太大。Screws 14 are used to limit the first 13 and second 15 of the cross baffles to limit and position the jig trolley in the lateral direction; the side baffles 12 are used to guide and position the jig chassis 19 laterally to ensure the positioning accuracy in the horizontal direction. The screw rod 6 feeds to the right, giving the pressure plate 10 a force to the right. The pressure plate 10 adopts a large size in the circumferential direction, which is a little larger than the cross-sectional size of the push rod 11, and can be stressed evenly, so as not to jump too much in the circumferential direction.
如图5所示：顶杆11右端采用楔形，能够配合夹具底盘19的楔形块21，缓缓挡住夹具底盘19，从而挡住上面的盘形夹具18，防止冲击太大。As shown in Figure 5: the right end of the ejector rod 11 adopts a wedge shape, which can cooperate with the wedge-shaped block 21 of the clamp chassis 19 to slowly block the clamp chassis 19, thereby blocking the disc-shaped clamp 18 above and preventing the impact from being too large.
如图3所示：采用横挡板一13与横挡板二15与侧向方向的侧挡板12，实现小车各自方向的定位，方便主轴下滚压头的准确滚压。尤其采用把手16对螺杆6的周向旋转，使得螺杆6能够进行右向微量进给，保证了该横向(顶杆11方向)的定位精度，把手16也方便容易使力，而且可以拆卸下来换为扳手使用较大拧力。As shown in Fig. 3: the first transverse baffle 13, the second transverse baffle 15 and the side baffle 12 in the lateral direction are used to realize the positioning of the trolley in each direction and facilitate the accurate rolling of the rolling head under the main shaft. In particular, the handle 16 is used to rotate the screw rod 6 in the circumferential direction, so that the screw rod 6 can be fed in a small amount in the right direction, which ensures the positioning accuracy of the horizontal direction (the direction of the ejector rod 11). The handle 16 is also convenient and easy to force, and can be disassembled and replaced. Use a higher torque for the wrench.
底座2采用双侧肋板支撑，能够保证因把手16向下用力过大，而导致底座2和支架1松动或破坏，相当于加强筋的支撑作用，另外相对节省床身空间。The base 2 is supported by double-sided ribs, which can ensure that the base 2 and the bracket 1 are loosened or damaged due to excessive downward force of the handle 16, which is equivalent to the supporting effect of the reinforcing ribs, and relatively saves the bed space.
本发明的工作原理是：The working principle of the present invention is:
当设备开始工作时，逆时针用榔头轻轻敲击把手16，螺杆6逐渐向左方向移动，压板10和顶杆11脱开，然后取下顶杆11，拉动拉手20向左移动，夹具底盘19处于最左边，盘形夹具18固定在夹具底盘19上，将盘状工件放置到盘形夹具18中，然后用手推回到右端，被右端挡住后停止，然后将顶杆11放置到压板10和楔形块21之前，让顶杆11左端面处于压板10右端面中，保证均匀受力，然后顺时针用榔头轻轻敲击把手16，螺杆6逐渐向右方向移动，压板10顶紧顶杆11，顶杆11逐渐压紧楔形块21，保证顶杆方向的再次压紧定位，垂直方向靠横向限位，然后整个装夹过程结束，开始加工盘状工件。When the equipment starts to work, gently tap the handle 16 counterclockwise with a hammer, the screw 6 gradually moves to the left, the pressure plate 10 and the ejector rod 11 are disengaged, and then the ejector rod 11 is removed, and the handle 20 is pulled to move to the left, and the clamp chassis 19 is on the far left, the disc-shaped fixture 18 is fixed on the fixture chassis 19, the disc-shaped workpiece is placed in the disc-shaped fixture 18, and then pushed back to the right end by hand, stopped after being blocked by the right end, and then the ejector rod 11 is placed on the pressure plate 10 and wedge-shaped block 21, let the left end surface of the ejector rod 11 be in the right end surface of the pressure plate 10 to ensure uniform force, and then lightly tap the handle 16 clockwise with a hammer, the screw 6 will gradually move to the right, and the pressure plate 10 will be pressed against the top The rod 11 and the ejector rod 11 gradually press the wedge-shaped block 21 to ensure the re-compression and positioning of the ejector rod direction, and the vertical direction is limited by the lateral direction. Then the whole clamping process ends and the disc-shaped workpiece starts to be processed.
