Clamping; when using the above-mentioned traditional fixtures, the workers use pressure plates and screws to press the workpiece to be processed on the machine tool, and then use a micrometer to correct the straightness and levelness. A lot of time will be spent on this process. This leads to long workpiece correction time, long mechanical standby time, and low work efficiency. Especially for mass production, each workpiece needs to be corrected, and the shortcomings of low work efficiency are particularly prominent.

Usually, the pressure plate 17 of different shapes can be set according to the different parameters such as the shape and size of the workpiece to be processed, as long as the same technical effect can be satisfied.

当本实用新型所提供的线切割夹具装夹工件时,将工件放置于弹性底板18上,然后转动压盘17,使得工件保持所需要的角度,然后对工件进行加工,待工件加工完毕后,转动偏心轮3,此时与偏心轮3铰接的顶板13就会沿着支撑杆1向上滑动,即与顶板13下表面连接的导向杆14也向上运动,线切割夹具松开工件,完成了对一个工件的装夹;接着,将另一个待加工的工件放置在弹性底板18上,向相反方向转动偏心轮3,线切割夹具对工件进行了装夹。When the wire cutting fixture provided by the utility model clamps the workpiece, the workpiece is placed on the elastic base plate 18, and then the pressure plate 17 is rotated so that the workpiece maintains the required angle, and then the workpiece is processed. After the workpiece is processed, Turn the eccentric wheel 3, the top plate 13 hinged with the eccentric wheel 3 will slide upwards along the support rod 1, that is, the guide rod 14 connected to the lower surface of the top plate 13 also moves upwards, and the wire cutting clamp releases the workpiece, and the alignment is completed. Clamping of a workpiece; then, another workpiece to be processed is placed on the elastic base plate 18, and the eccentric wheel 3 is rotated in the opposite direction, and the wire cutting fixture clamps the workpiece.

由此看出,成批量生产时,上述线切割夹具对工件重复装夹只需要转动偏心轮3即可,因此,本实用新型所提供的线切割夹具缩短了装夹时间,从而提高了装夹效率,进而缩短了机械待机时间,降低了加工成本。It can be seen from this that, during mass production, the above-mentioned wire cutting fixture only needs to rotate the eccentric wheel 3 to repeatedly clamp the workpiece. Therefore, the wire cutting fixture provided by the utility model shortens the clamping time, thereby improving the clamping time. Efficiency, thereby shortening the mechanical standby time and reducing the processing cost.

另外,为了保证工件可以较为稳定的被夹紧在弹性底板18与压盘17之间,通常本领域技术人员可以在支撑杆1的上端设置挡板6,挡板6与顶板13之间设置有弹簧5。当顶板13向上滑动的时候,弹簧5被压缩,顶板13向下滑动的时候,弹簧5对顶板13施加向下的压力,从而就使得压盘17对工件施加向下的压力,进而保证了将工件稳定的夹紧在压板17与弹性底板18之间。In addition, in order to ensure that the workpiece can be clamped relatively stably between the elastic bottom plate 18 and the pressure plate 17, generally those skilled in the art can install a baffle plate 6 on the upper end of the support rod 1, and a spring 5. When the top plate 13 slides upwards, the spring 5 is compressed, and when the top plate 13 slides downwards, the spring 5 exerts a downward pressure on the top plate 13, so that the pressure plate 17 applies a downward pressure to the workpiece, thereby ensuring that the The workpiece is stably clamped between the pressure plate 17 and the elastic bottom plate 18 .

此外,不同批次的工件的形状、大小会有一定的差异,这样所需要的压力也不相同,为此可以在支撑杆1的上端设置有调节螺母7,并且调节螺母7与挡板6的上表面接触,根据不同的需求拧动调节螺母7即可调节弹簧5的压缩状态,也就是调节压力的大小。In addition, the shape and size of different batches of workpieces will have certain differences, so the required pressure is also different. For this reason, an adjusting nut 7 can be arranged on the upper end of the support rod 1, and the adjustment nut 7 and the baffle plate 6 The upper surface is in contact, and the compression state of the spring 5 can be adjusted by turning the adjusting nut 7 according to different requirements, that is, the pressure can be adjusted.

When the position of the guide rod 14 needs to be fine-tuned, screw The adjustment of the length of the guide rod 14 positioned below the fine-tuning nut can be realized by moving the fine-tuning nut 10. The upper limit block 9 can be processed into an integral structure with the top plate 13, or can be processed into a split structure, and then fixed. In the embodiment of the utility model, the upper limit block 9 and the top plate 13 are preferably set as a split structure, and then passed The screws are fixed, and of course the lower limit block 11 can also be set between the lower end surface of the fine-tuning nut 10 and the upper surface of the top plate 13 .

本领域技术人员还可以在导向杆14上设置延伸方向与导向杆14的延伸方向相同的键槽,微调通孔内表面具有相应的配合键槽,键槽与配合键槽内设置有防滑键12,这样在工作过程中导向杆14就不会发生转动,进而提高了加工的精确性。Those skilled in the art can also set on the guide rod 14 the same keyway with the extension direction of the guide rod 14, the inner surface of the fine-tuning through hole has a corresponding matching keyway, and an anti-skid key 12 is arranged in the keyway and the matching keyway, so that when working During the process, the guide rod 14 will not rotate, thereby improving the processing accuracy.

此外,也可以在顶板13上设置位置调节通孔,支撑杆1穿出位置调节通孔,此时支撑杆1可以设置延伸方向与支撑杆1的延伸方向相同的键槽,位置调节通孔内表面具有相应的配合键槽,键槽与配合键槽内设置有键8,这样就限制了顶板13相对于支撑杆1转动,进一步的保证了加工的精确性。In addition, a position adjustment through hole can also be set on the top plate 13, and the support rod 1 passes through the position adjustment through hole. At this time, the support rod 1 can be provided with a keyway whose extension direction is the same as that of the support rod 1, and the inner surface of the position adjustment through hole There is a corresponding matching keyway, and the keyway and the matching keyway are provided with a key 8, which limits the rotation of the top plate 13 relative to the support rod 1, and further ensures the accuracy of processing.

Fixing, of course, can also be other fixing forms, as long as the same technical effect can be achieved.

为了保证下底座19与偏心轮3接触,并且保证偏心轮3的较小,通常可以在下底座19与偏心轮3相对应的部位向上凸起2,该凸起2可以与下底座19为一体式结构,为了加工方便还可以将凸起2与下底座19设置为分体式结构,然后将凸起2与下底座19固定在一起,一般情况可以通过螺钉将凸起2与下底座19固定,当然也可以是其它的固定方式,只要能达到相同的技术效果即可。In order to ensure that the lower base 19 is in contact with the eccentric wheel 3, and to ensure that the eccentric wheel 3 is relatively small, it is usually possible to protrude 2 upward at the position corresponding to the lower base 19 and the eccentric wheel 3, and the protrusion 2 can be integrated with the lower base 19 Structure, for the convenience of processing, the protrusion 2 and the lower base 19 can also be set as a split structure, and then the protrusion 2 and the lower base 19 can be fixed together.
