Embodiment Construction

[0034] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0035] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "fixed", "integrated", "left", "right" and si...

Abstract

The invention discloses a full-automatic assembling and producing method for an expansion screw. The indexing rotation procedure, the three-piece feeding procedure, the expansion pipe feeding procedure, the expansion threaded rod feeding procedure, the threaded rod and nut screwing procedure and the discharging procedure are included. In the three-piece feeding procedure, an elastic sheet, a nut and a gasket are arranged at the assigned position of a jig together; in the expansion pipe feeding procedure, an expansion pipe is placed at the assigned position of the jig; in the expansion threadedrod feeding procedure, an expansion threaded rod is conveyed to the jig and sequentially penetrates through the expansion pipe, the gasket and the elastic sheet to straightly abut against the nut; inthe threaded rod and nut screwing procedure, the expansion threaded rod and the nut are screwed; and in the discharging procedure, the assembled expansion screw is conveyed to the next procedure. Thefull-automatic assembling and producing method has the beneficial effects that an expansion bolt can be automatically assembled without manual work, the assembling efficiency is high, and the productqualification rate can be effectively increased; and according to the full-automatic assembling and producing method, positioning is accurate, the assembling precision is high, and the full-automaticassembling and producing method is suitable for large-batch expansion screw assembling and producing.

Description

technical field [0001] The invention relates to the field of assembly and production of expansion screws, in particular to an automatic assembly and production method of expansion screws. Background technique [0002] Expansion bolt is a special threaded connection used to fix pipeline supports / hangers / brackets or equipment on walls, floors, and columns. It generally consists of countersunk bolts, expansion tubes, flat washers, spring pads and hex Composition of nuts. The traditional expansion bolts use manual assembly of the various parts of the expansion bolts, which has low assembly efficiency, unstable product quality, and low product qualification rate. Can not meet mass production. Therefore, there are defects in the prior art and need to be improved. Contents of the invention [0003] The invention provides a fully automatic assembly and production method for expansion screws, which solves the above-mentioned problems. [0004] In order to solve the above proble...
