Device for clamping and releasing workpiece

Abstract

The invention relates to the field of metal tool manufacturing, and provides a device for clamping and releasing a workpiece. The device comprises a base, and is characterized in that the base is provided with a drive mechanism and a positioning base, the drive mechanism is connected with a pressing block through a transmission mechanism, an opened working window is formed in the pressing block and is right opposite to the positioning base, and a positioning pin is arranged at the center of the upper end face of the positioning base. Different from a traditional positioning mode depending on positioning of the appearance or side face of the workpiece, the structural design of the independent positioning pin is adopted, positioning references of some processes can be unified, machining precision can be greatly improved, and then the process of clamping the workpiece at a time and machining the workpiece multiple times is achieved.

Description

technical field [0001] The invention relates to the field of metal tool manufacturing, in particular to a device for clamping and releasing workpieces. Background technique [0002] In the process of traditional metal tool processing, due to the irregular shape of the workpiece to be processed, it is not easy to control the accuracy during drilling and other operations, so repeated clamping is required, and the processing accuracy of the workpiece is repeatedly required to be tested, and the workload is very large. , there are a lot of defective products. [0003] For example, in the manufacturing process of metal tool pliers, the center hole needs to be punched or twisted, and the center hole of the tool pliers is not set on a plane. The traditional process uses a tooling fixture to fix the two ends of the tool pliers to implement drilling, but tool pliers are often prone to accidents. Various directions are offset, resulting in poor stamping accuracy. There is also a met...

[0002] In the process of traditional metal tool processing, due to the irregular shape of the workpiece to be processed, it is not easy to control the accuracy during drilling and other operations, so repeated clamping is required, and the processing accuracy of the workpiece is repeatedly required to be tested, and the workload is very large. , a lot of defective products

[0003] For example, during the manufacturing process of metal tool pliers, the center hole needs to be punched or twisted, and the center hole of the tool pliers is not set on a plane. The traditional process uses a tooling fixture to fix the two ends of the tool pliers for drilling, but tool pliers are often prone to accidents. Offset in various directions, resulting in poor stamping accuracy

It is also used to place a soft material pad on the plane where the workpiece is placed on the fixture to determine the position of the workpiece. The effect is better than the former, but it still lacks efficiency and accuracy.
