Anti-retreating vice polishing and positioning device

Abstract

The invention discloses an anti-retreating vice polishing and positioning device which comprises a rack. A feeding frame is fixed to the top of the rack. A feeding guide groove is formed in the feeding frame; a feeding push plate is installed below the feeding frame and connected with a first push-pull device. A positioning plate fixed with the rack is mounted below the feeding push plate; not less than three positioning cylinders and a positioning pin corresponding to the hinge hole of the clamp body penetrate through the positioning plate and are connected to the positioning plate in a sliding manner; the positioning pin and the positioning cylinders are connected with a second push-pull device; a positioning block is installed in cooperation with the positioning plate and connected with a third push-pull device. The positioning block and the feeding push plate are located on the same side and fixed to the machine frame, so that during grinding, the pliers cannot shrink backwards due to extrusion, vibration and instability during grinding are reduced, the workpiece machining quality is improved, in addition, material clamping can be effectively prevented, and chips can be automatically discharged.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to an anti-retreat vise grinding and positioning device. Background technique [0002] A vise is a widely used hardware tool that can be used to cut wires, iron wires, thin iron sheets, etc. The cutting edge of the vise needs to be cut and processed. In order to realize the automatic processing of the vise, our company has invented a precise positioning adjustment structure for pliers processing as shown in the invention patent CN113560921A. When it is positioned, the direction in which the positioning cylinder clamps the pliers is consistent with the direction of feeding, and is opposite to the direction in which the grinding device gives pressure to the pliers; while the gas in the cylinder will decrease in volume under pressure, resulting in unstable clamping of the cylinder , It is easy to cause the pliers to vibrate during grinding, which will affect the grinding effect. ...

AI Technical Summary

Problems solved by technology

When it is positioned, the direction in which the positioning cylinder clamps the pliers is consistent with the direction of feeding, and is opposite to the direction in which the grinding device gives pressure to the pliers; while the gas in the cylinder will decrease in volume under pressure, resulting in unstable clamping of the cylinder , it is easy to cause the pliers to vibrate during grinding, which will affect the grinding effect

In addition, its positioning device is only positioned by the cylindrical rod and the center of gravity of the pliers, resulting in inaccurate positioning

Again, when feeding, after pushing the material, when the pliers fall, due to the falling vibration, the bottom pliers will deflect toward the discharge port, causing the tails of the upper pliers to overlap with the tails of the bottom pliers on the same level , causing the subsequent feeding to be stuck and unable to feed

Finally, existing units do not have automatic chip removal, so improvements are needed
