Screw rod and nut assembling device

Abstract

The invention discloses a screw rod and nut assembling device, and aims to provide an assembling device which is reasonable whole structure distribution, is capable of completing feeding through simple, low-requirement operation, enabling the automatic adjusting capacity to be obtained during a feeding process and carrying out effective and accurate positioning after the feeding is completed, has a quick positioning process, is unlikely to cause additional damage and is capable of ensuring the smoothness and the stability of the whole assembling process. The screw rod and nut assembling device comprises a nut feeding device, a screw rod feeding device, an upper nut device, an upper screw rod device and a screwing device. The screw rod and nut assembling device disclosed by the invention has the beneficial effects that the screw rod and nut assembling device can be suitable for feeding screw rods in multiple length specifications in sequence; the feeding operation is simple and quick, adaptive adjustment can be automatically carried out during a follow-up blanking process, the blanking position is accurate, and the feeding difficulty is low; two-end assembling of the multiple screw rods can be simultaneously carried out, and the production efficiency is increased; the error amount can be adapted to through self adjustment of a buffer spring, the requirement on accurate feeding amount of an air cylinder is reduced, and better security is provided for the stability of the assembling process.

Description

technical field [0001] The invention belongs to the technical field of screw nut assembly, and in particular relates to a screw nut assembly device. Background technique [0002] In production, it is necessary to assemble the screw and nut in many cases. Although the current screw and nut assembly device can realize the assembly function to a certain extent, it is still difficult to achieve in terms of assembly efficiency, self-adjusting ability in the assembly process, and the efficiency of feeding and loading. There are still many deficiencies in terms of stability and rationality. Chinese patent announcement number CN201677167U discloses an automatic nut tightening machine, in which a spring is arranged on the top of the DC motor, and the elastic return of the spring is used to drive the DC motor to move up and down. The DC motor is fixed on the optical axis through a linear bearing, and the bottom of the DC motor is sequentially It is equipped with a planetary reducer, ...

AI Technical Summary

Problems solved by technology

The disadvantage of this utility model is that there is no perfect feeding and positioning function. It is necessary to control the position of the screw or nut in advance and fix it during the working process, and then perform more than one screwing fit. During the screwing process, it must be through the computer or The controller precisely controls the screwing depth, otherwise it is easy to cause problems such as excessive screwing, extrusion of screwed parts and nuts or screws, resulting in damage to parts, etc.
