Self-tapping clamp

Abstract

The invention discloses a self-tapping clamp. The self-tapping clamp comprises a transverse track for feeding materials and a longitudinal guide way assembly which is used for conveying a workpiece and positioning the workpiece to be machined, the tail end of the transverse track is connected with the front end of the guide way assembly, a push plate which is pushed by an air cylinder is arranged in rear of a portion of the transverse track, the portion of the transverse track is connected with the front end of the guide way assembly, the push plate can move forwards to smoothly push a to-be-machined workpiece which right faces an inlet of the guide way assembly on the transverse track into the guide way assembly, a tapping machine is respectively arranged above front and rear sections of the guide way assembly, and holes in different positions of the to-be-machined workpiece are tapped respectively through the two tapping machines. By means of the self-tapping clamp, one-time tapping of a part can be finished, the efficiency is increased, the size is small, the structure is simple, the appearance is attractive, the operation is easy, tapping qualities are reliable, costs are low, and the self-tapping clamp is particularly suitable for self-tapping of connecting plate parts.

Description

[0001] technical field [0002] The invention relates to a special tooling equipment for one-time molding suitable for porous parts such as connecting plates or porous parts such as hardware, in particular to an automatic tapping fixture. Background technique [0003] There are 2-3 threaded holes on each connecting plate of many existing connecting plate parts, generally one M8 and two M4 small holes. Traditionally, the workpiece needs to be manually placed into the tapping machine fixture during tapping operation. However, because the size of connecting plate parts is generally small, about 20*16, the threaded holes on the top are very close together, and it cannot be tapped by a multi-axis tapping machine at one time, so tapping one hole at a time usually requires Multiple clamping, this tapping method has more processes, and the operation is more complicated, and the efficiency is not high; and there is no tooling equipment that can tap all the holes of this type of part...

Problems solved by technology

[0003] There are 2-3 threaded holes on each connecting plate of many existing connecting plate parts, generally one M8 and two M4 small holes, the traditional During the upper tapping operation, the workpiece needs to be manually placed into the tapping machine fixture. However, because the size of the connecting plate parts is generally small, about 20*16, the upper threaded holes are very close to each other, so it cannot be used for multi-axis tapping. The tapping machine completes tapping at one time, so each time tapping a hole, it usually needs multiple clamping. This tapping method has more processes, and the operation is more complicated, and the efficiency is not high; and there is no one-time tapping in the entire industry. Tooling for all holes in such parts
