Buffer nail assembly tool

Abstract

The invention relates to the technical field of machinery, in particular to buffer nail assembly tool. The buffer nail assembly tool is characterized in that a left guide pillar and a right guide pillar are arranged in a frame, a press-in air cylinder module, a clamping air cylinder module and a stretching air cylinder module are arranged along the guide pillars from top to bottom, a plurality of pressing heads of buffer nails are arranged on the lower surface of the press-in air cylinder module, a shell body positioning mould is arranged above the clamping air cylinder module, the press-in air cylinder module controls the pressing heads to move up and down along the guide pillars, and the stretching air cylinder module controls the clamping air cylinder module to move up and down along the guide pillars. Compared with the prior art, the buffer nail assembly tool utilizes an automatic assembly mode, achieves a series of functions such as automatic assembly of the buffer nails, neglected assembly of the buffer nails and in-place assembly detection by automatically controlling a press-in air cylinder, clamping air cylinders, a stretching air cylinder and a photoelectric sensor through a PLC, improves stability in the assembly process, has the effect of reducing scrapping of the product, is easy and convenient to operate and lowers work strength of operating personnel.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a buffer nail assembling tool. Background technique [0002] In the current car headrest, a buffer mechanism is designed, which is assembled by 4 buffer nails and a plastic base, which plays the role of buffer protection for the head. Generally, the operator manually presses the buffer nails forcibly. However, relying on the manual method to assemble the buffer nails will produce many disadvantages: a. It is laborious and time-consuming, and the assembly of a buffer nail usually takes about 2 minutes, which is not suitable for mass production; b , Manual can not ensure that the buffer nails will not be missing; c. The material of the buffer nails is EPDM, which is generally called rubber, which is characterized by softness and large elastic deformation. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, an...

[0002] In the current car headrest, a buffer mechanism is designed, which is assembled by 4 buffer nails and a plastic base, which plays a role of buffer protection for the head. Generally, the operator manually presses the buffer nails However, relying on the pure manual method to assemble the buffer nails will produce many disadvantages: a. It is laborious and time-consuming. The assembly of a buffer nail often takes about 2 minutes, which is not suitable for mass production; b. . Labor cannot guarantee that the buffer nails will not be missing; c. The material of the buffer nails is EPDM. Generally speaking, it is rubber.
