Testing apparatus for verticality of top face with end face of slide rail

Abstract

The invention disclose a detecting device for the verticality between a top surface and an end surface of a lead rail, which includes a locating plate and a dial indicator mounting piece; the locatingplate includes a side part and a connecting part which mutually form an L shape; the dial indicator mounting piece is a T-shaped structure; a T-shaped vertical is fixed on the connection part; a T-shaped transverse part is vertical to a side panel; the two end parts of the T-shaped transverse part are provided with dial indicator mounting structures; the side of the side part facing to the connection part is respectively provided with an end surface locating column butted with the end surface of the vertical part of a T-shaped lead rail, a top surface locating column butted with the top surface of the vertical part of the T-shaped lead rail as well as a side surface locating bead. The detecting device for the verticality between the top surface and the end surface of the lead rail is assembled by a plurality of parts; compared with a welding piece, the detecting device for the verticality between the top surface and the end surface of the lead rail has a beautiful appearance and is conveniently processed; the opposite height positions of the locating plate and the dial indicator arranged on the dial indicator mounting piece can be adjusted within a certain range, thus being capable of leading the device to be applied on the lead rails with different types, have high adaptation performance and save cost for the enterprise.

Description

technical field [0001] The invention relates to a device for detecting the perpendicularity between the top surface and the end surface of a guide rail, in particular to a device for detecting the perpendicularity between the top surface and the end surface of a T-shaped guide rail for a van elevator. Background technique [0002] The van elevator achieves a smooth vertical lift by sliding up and down along the T-shaped guide rail. The T-shaped horizontal part of the guide rail is fixed to the building, and the T-shaped vertical part is provided with a working surface that slides and fits with the elevator car. The verticality between the side working surface and the bottom surface outside the transverse part, the verticality between the top surface and the end surfaces of the two ends of the guide rail, and the straightness of the entire T-shaped guide rail are all criteria for evaluating the quality of the guide rail. In the past, the detection device used to measure the ...

AI Technical Summary

Problems solved by technology

In the past, the detection device used to measure the verticality between the side working surface and the bottom surface was generally welded into a whole after calibration, and it could not be adjusted after production. At the same time, each type of detection device that cannot be adjusted can only detect a specific type of guide rail, which is not very applicable and increases the cost of use.
