Workpiece clamping and quick-changing device for high-speed precision punching machine

Abstract

The invention belongs to the field of machining, and particularly relates to a workpiece clamping and quick-changing device for a high-speed precision punch press. The workpiece clamping and quick-changing device comprises a base station, a mounting seat and a quick connector. A first groove is formed in the mounting seat, third grooves are formed in the side surfaces of the mounting seat, and auxiliary clamping jaw assemblies are mounted in the third grooves in a clamping manner. One end of the quick connector is clamped and mounted in the first groove, and the other end of the quick connector is fixedly connected with a pneumatic manipulator. According to the clamping and quick-changing device, different types of manipulators can be quickly changed through cooperation of the mounting seat and a clamping sleeve, changing steps are simplified, and the manipulators are more convenient to change and operate. When the quick connector and the mounting seat are mounted in a matched mode, anair pipe does not need to be additionally connected, and therefore replacement time is greatly saved. The workpiece clamping and quick-changing device is more stable when clamping a workpiece, falling is avoided, the auxiliary clamping jaw assemblies are convenient to replace, and the auxiliary clamping jaw assemblies can be quickly replaced according to shape of a workpiece in use.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a workpiece clamping and quick-changing device for high-speed precision punching machines. Background technique [0002] Punching machine is a desktop stamping press. In the process of punching and feeding, if manual feeding is used, the efficiency is low and there are unsafe factors. Therefore, most of the current punching machines use manipulators to load materials, and the manipulators can automatically complete the process according to the preset program. The specified action realizes the automatic picking and delivery of objects. [0003] In the process of working with the manipulator and the punching machine, the following problems often occur. The first is that there are many kinds of stamping parts and different shapes. During production, workers need to often change different manipulators to produce different products. The existing manipulators are in Th...

[0002] Punching machine is a desktop stamping press. In the process of punching and feeding, if manual feeding is used, the efficiency is low and there are unsafe factors. Therefore, most of the current punching machines use manipulators to load materials, and the manipulators can automatically complete the process according to the preset program. Prescribed actions to realize automatic gripping and delivery of objects

[0003] In the process of working with the manipulator and the punching machine, the following problems often occur. The first is that there are many kinds of stamping parts and different shapes. During production, workers need to often change different manipulators to produce different products. The existing manipulators are in The process of replacement is complicated, which delays a lot of production time; moreover, when the manipulator grasps and transports the parts, it is easy to cause the parts to drop, which may lead to production suspension or even damage to the punching machine. Therefore, the present invention provides a high-speed precision Part clamping quick change device for punch press
