Rapid locking mechanism

Abstract

The invention discloses a rapid locking mechanism. The rapid locking mechanism comprises a fixed base of a hollow annular structure, a locking stud with the bottom end fixed into an annular cavity of the fixed base, a locking nut arranged at the upper end of the locking stud in a sleeving mode, a limiting ring arranged on the locking stud in a sleeving mode, and a guide locking mechanism. The upper end of the limiting ring is connected with the lower end of the locking nut. The guide locking mechanism comprises a guide locking pressing column and a guide screw, wherein the guide locking pressing column is arranged on the locking stud in a sleeving mode, the upper end of the guide locking pressing column is connected with the lower end of the limiting ring, the middle of the guide locking pressing column protrudes outwards to form a pressing table, a spiral groove is machined in the side wall of the lower portion of the pressing table, the tail portion of the spiral groove is connected with a linear section groove, one end of the guide screw is fixed to the fixed base, and the other end of the guide screw extends into the linear section groove and the spiral groove of the guide locking pressing column. The guide locking mechanism can rotate up and down by rotating the nut so that the guide locking mechanism can get close to parts to press the parts or get away from the parts to release the parts. The rapid locking mechanism is reliable in locking and convenient to operate, and is not limited by the installation positions or shapes of the parts.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a manual quick locking mechanism, which is used for quick locking of parts or equipment on a workbench. Background technique [0002] At present, operating instruments, equipment, and parts to be processed are installed on many machine tool workbenches, test platforms, equipment mounting brackets, and tripods. If they need to be installed and disassembled manually, a set of manual quick locks must be installed and fixed on them. The mechanism can be installed and fixed or disassembled at any time. Taking fixing parts on the machine tool table as an example, according to the searched information and patents, there are mainly the following methods: [0003] At present, the most commonly used method is to fix the parts on the machine tool table through the combination of the pressure plate and the fixing bolt. the goal of. The advantage of this method is ...

AI Technical Summary

Problems solved by technology

The disadvantage is: the installation position, installation method and shape of the parts on the machine tool table have certain restrictions. After the locking mechanism is released, the position of the parts and the locking pressure plate cannot be completely separated, and the parts need to be moved to the locking pressure plate first. In order to carry parts up and down, this kind of mechanism occupies a large internal space

[0006] The above methods of fastening parts on the workbench all have certain limitations or are inconvenient to operate, especially when the fixed position of the parts is not easy to reach by hand or tools, or when the parts are in an inclined position, at this time on the workbench It will be very difficult or impossible to fix and remove the parts
