Bullet latch mechanism

Abstract

The invention relates to a spring type bolt lock mechanism. The spring type bolt lock mechanism comprises a cylinder clamping sleeve and a tongue bolt, wherein the cylinder clamping sleeve can be mounted on a to-be-fixed appliance through a fixing supporting seat; the tongue bolt is arranged in the cylinder clamping sleeve; a through hole is formed in the axial direction of the cylinder clamping sleeve; a guide groove is formed in the radial direction of the inner circumferential wall of the through hole, and an annular limiting groove is formed in the circumferential direction of the inner circumferential wall of the through hole; the guide groove and the limiting groove are communicated with each other and are at least communicated with an end part of the cylinder clamping sleeve; the tongue bolt comprises an operating rod, a sliding part and a tongue bolt head part capable of extending into a positioning hole in a workbench; the sliding part is in sliding fit with the through hole of the cylinder clamping sleeve; guide blocks which are matched with the guide groove and the limiting groove respectively are arranged at the periphery of the sliding part; the fixing supporting seat is arranged at the end part of the cylinder clamping sleeve, and a hole, through which the tongue bolt head part can penetrate, is formed in the middle of the cylinder clamping sleeve. Other pieces of auxiliary positioning equipment are not needed, and the spring type bolt lock mechanism is small in occupied space, simple in structure, easy to manufacture, convenient to use, quick to operate, higher in production efficiency, high in generality, and applicable to various appliances including stop blocks, parts, detection tools and tools.

Description

technical field [0001] The invention relates to a tooling auxiliary tool, in particular to a spring latch mechanism capable of quickly positioning blocks, pads, tooling, inspection tools, etc. on the worktable. Background technique [0002] In the automatic stamping, automobile welding, machining, assembly and other workshops of automobiles and other manufacturing industries, parts, inspection tools, tooling, etc. with sliding planes, moving planes, and rotating planes are often fixed on the work table according to the needs of the work. When fixing, the operator usually uses blocks, pads or other tools to block or prevent the sliding, moving, rotating, etc. of the appliance to be fixed. Use blocks, pads or other tools to block or prevent sliding, movement, and rotation. The fixed spatial direction is relatively single, and the fixation is very unstable. Multiple blocks, pads, and other tools are required to limit other directions, so even if It can be fixed, but the operat...

AI Technical Summary

Problems solved by technology

Use blocks, pads or other tools to block or prevent sliding, movement, and rotation. The fixed spatial direction is relatively single, and the fixation is very unstable. Multiple blocks, pads, and other tools are required to limit other directions, so even if It can be fixed, but the operation method is cumbersome, the operation time is long, and the labor productivity is low

In response to this situation, the usual method is to install auxiliary devices on the fixed appliance, such as the disclosed technology of "A Lithium Battery Core Package Pole Bolt Locking Auxiliary Fixture" (CN203225313U), but its structure is limited to specific tooling , the versatility is not strong, and it is not suitable for the needs of various use environments
