Clamping equipment special for looper holder drilling and tapping

Abstract

The invention relates to clamping equipment special for looper holder drilling and tapping. The clamping equipment comprises a bottom plate, a supporting plate, pressing plates, a pressing plate sliding air cylinder, fastening spanners, workpiece positioning blocks and side face positioning devices. The multiple workpiece positioning blocks are evenly distributed on the upper portion of the front face of the supporting plate. Each workpiece positioning block is provided with a positioning rod for inserting installation of workpieces. The portion, on the right side of each workpiece positioning block, of the supporting plate is provided with one side face positioning device. The clamping equipment special for looper holder drilling and tapping is specially designed for looper holder machining, and has the advantages of being simple in structure, easy and convenient to use, low in manufacturing cost, high in practicability and the like. By using the clamping equipment, multiple workpieces can be clamped at a time, machining of multiple working procedures can be completed after one-time clamping, and therefore the purposes of increasing the production speed, improving the product quality, reducing the labor cost and increasing enterprise benefits are achieved.

Description

technical field [0001] The invention relates to a clamping fixture in the technical field of machining, in particular to a special clamping device for drilling and tapping a looper frame. Background technique [0002] During the processing of the sewing machine looper frame, the screw mounting holes on the screw mounting surface need to be milled and flattened, drilled, tapped, etc. At present, it needs to use multiple fixtures and go through multiple processes to complete the processing, so the following problems are prone to occur: 1. The existing fixtures can only clamp one workpiece at a time, so the processing speed is slow. 2. The workpiece needs to be clamped repeatedly, which not only increases the time for disassembling and assembling the workpiece, but also increases the possibility of errors, reduces the precision of the product, affects the product quality and increases the workload of the staff. 3. The shape of the workpiece is special, and the clamping and pos...

AI Technical Summary

Problems solved by technology

At present, it needs to use multiple fixtures and go through multiple processes to complete its processing, so the following problems are prone to occur: 1. The existing fixtures can only clamp one workpiece at a time, so the processing speed is slow

2. The workpiece needs to be clamped repeatedly, which not only increases the time for disassembling and assembling the workpiece, but also increases the possibility of errors, reduces the precision of the product, affects the quality of the product and increases the workload of the staff

3. The shape of the workpiece is special, and the clamping and positioning are cumbersome and complicated, which will also affect the processing speed and accuracy

4. Manual clamping requires a high level of technical staff, it is difficult to ensure the consistency of workpiece processing, and the surface of the workpiece is easily scratched during clamping, which affects product quality
