Description
技术领域Technical Field

背景技术Background Art
冲孔工艺是一种常用于金属加工的加工工艺，它通过使用冲动模具，在金属材料上制造孔洞、凸台等形状，冲孔工艺具有高效、精确、重复性好等特点并广泛应用于制造业中，在冲孔时首先需要将工件牢牢的固定住，然后再对其进行加工，但是传统的冲孔夹持装置仍存在一些缺点，比如：传统装置在进行夹持时夹具与工件表面贴合，在冲孔的过程中，冲头与工件表面接触的一瞬间会产生巨大的冲击，这种冲击会随着工件传递到夹具上，由于夹具与工件的表面为刚性接触，这会导致工件发生形变，从而出现夹具夹持松动的情况发生。Punching technology is a commonly used processing technology for metal processing. It uses impulse dies to create holes, bosses and other shapes on metal materials. The punching process has the characteristics of high efficiency, precision, good repeatability, etc. and is widely used in the manufacturing industry. When punching, the workpiece must be firmly fixed first and then processed. However, traditional punching clamping devices still have some shortcomings. For example, when the traditional device is clamped, the clamp fits the surface of the workpiece. During the punching process, a huge impact will be generated at the moment the punch contacts the surface of the workpiece. This impact will be transmitted to the clamp along with the workpiece. Since the clamp and the surface of the workpiece are in rigid contact, this will cause the workpiece to deform, resulting in loose clamping of the clamp.

At this time, the second motor 43 will move downward with the threaded rod 44 and along the cylindrical barrel 42 The inner side slides downward, and then the bottom surface of the pressure plate 47 begins to contact the surface of the workpiece and squeezes the second spring 46. After the workpiece is fixed, the power of the second motor 43 is turned off, and then the workpiece can be processed. When punching operations are required on workpieces of different sizes, the power of the electric push rod 34 is started, and the electric push rod 34 extends and pushes the sliding block 31 to slide on the upper surface of the base 1. At this time, the limit block 32 slides in the first slide groove and squeezes the first spring 33. After the position adjustment is completed, the power of the electric push rod 34 is turned off, and then the workpiece is placed in the middle of the sliding block 31 and processed using the drill bit 2.
