Dovetail groove slide block type guide rail automatic tightening device

Abstract

The invention provides an automatic tightening device for a dovetail slide block type guide rail, which belongs to the technical field of slide block type guide rails. It includes a hexagonal screw head, a connecting belt, a belt tensioner, a driving pulley, the upper end of the tightening drive piston rod of the tightening drive cylinder is connected to the tightening support plate, and the first screwing shaft is rotatably arranged on the first screwing shaft support seat and the tightening support On the board, the second screw shaft is rotatably arranged on the second screw shaft support seat and the tightening support plate, the third screw shaft is rotatably arranged on the third screw shaft support seat and the tighten support plate, and the fourth screw shaft is rotatably arranged on On the fourth screw shaft support seat and the tightening support plate, there are hexagonal screw heads under the first screw shaft, the second screw shaft, the third screw shaft and the fourth screw shaft, and the connecting belt is closed and surrounded by the driving pulley , Belt tensioner, first arc wheel, second arc wheel, third arc wheel and fourth arc wheel. The invention automatically tightens the hexagon socket head screw to realize the fast connection of the connecting plate and the sliding block of the dovetail groove.

Description

technical field [0001] The invention relates to the technical field of slider-type guide rails, in particular to an automatic tightening device for a dovetail groove slider-type guide rail. Background technique [0002] A guide rail is a groove or ridge made of metal or other materials, which can bear, fix, guide a moving device or equipment and reduce its friction. Longitudinal grooves or ridges on the surface of rails for guiding and fixing machine parts, special equipment, instruments, etc. Guide rails, also known as slide rails, linear guide rails, and linear slide rails, are used in linear reciprocating motion applications. They have a higher rated load than linear bearings, and can bear a certain torque at the same time. They can achieve high-precision linear motion under high load conditions. . Guide rails are mainly divided into two categories: roller guide rails and ball guide rails. The application of guide rails in our daily life is also very common. For exampl...

AI Technical Summary

Problems solved by technology

Dovetail slider guide rail is a common guide rail, often used in painting equipment, hand-held sliding equipment, etc. This type of dovetail slider guide rail uses the dovetail groove structure to install the slider on the track, usually two sliders The blocks are also connected by connecting plates, and the connecting plates are installed on the dovetail sliders through hexagonal socket head screws. Now this kind of assembly is done manually, which not only has a low degree of automation, but also has a high labor intensity.
