Clamping and positing device capable of automatically aligning center and using method thereof

Abstract

The invention provides a clamping and positing device capable of automatically aligning center and a using method thereof, relating to a tooling clamp capable of automatically aligning center and being used in a plurality of fields of mechanical manufacture, printing, surface coating, electronic assembly and the like. The device comprises a driving mechanism, a clamping mechanism, a guiding mechanism and a supporting mechanism, wherein, the driving mechanism comprises a driving device and a driving force transmission device; the clamping mechanism comprises a positioning board (5); the supporting mechanism comprises a base (7) and a fixed seat (10); the driving mechanism, the clamping mechanism and the guiding mechanism are supported by the supporting mechanism; the driving mechanism drives the positioning board (5); the guiding mechanism ensures that the positioning board (5) moves according to a guided movement route; thus, the positioning board (5) can clamp a piece (13) to be processed, and the central reference position of the piece (13) to be processed is automatically positioned on the station for positioning a centre (central line or central point). The device can automatically align center and eliminate central line / point position offset.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a tooling fixture capable of automatic centering. The invention also relates to methods of use of the device. Background technique [0002] In the field of production and processing, the processing of many parts is required to be carried out at the position of the part determined by the design. During processing, it needs to be clamped and positioned, and then processed. Nowadays, the common clamping positioning is based on one side (face) or two adjacent sides (faces) of the part, so that for the processed part, the center is the reference part. If the error of the external dimension change is enough to affect the product When the quality is high, this clamping and positioning method cannot solve the quality problem. That is, the center reference position of the part cannot be guaranteed to remain unchanged. Lead to a large number of substandard products, and sometimes even seriously tr...

AI Technical Summary

Problems solved by technology

Now the common clamping positioning is based on one side (surface) or two adjacent sides (surfaces) of the part, so that for the processed part, the center is the reference part, if the error of the external dimension change is enough to affect the product When the quality is high, this clamping and positioning method cannot solve the quality problem

That is, the center reference position of the part cannot be guaranteed to remain unchanged

Lead to a large number of substandard products, and sometimes even seriously trouble the production of enterprises

[0003] Many enterprises have been plagued by the above quality problems for a long time, especially the silk screen printing process requires printing on the surface of plastic parts or glass parts, which used to be positioned on two adjacent sides (surfaces), when the printed graphics required to be based on the center of the part A large number of substandard products will be produced, which not only delays the production plan but also causes huge waste to the enterprise.
