An adjustable porous drilling jig for elevator guide rails

Abstract

The invention belongs to the field of elevator guide rails, and discloses an adjustable porous drill jig for an elevator guide rail. The adjustable porous drill jig comprises drill bushings arranged horizontally, wherein a support used for allowing the externally-arranged elevator guide rail to horizontally penetrate is arranged on the lower sides of the drill bushings; the support comprises sliding blocks and side plates, wherein the side plates are correspondingly arranged on the two sides of the sliding blocks; the drilling bushings are connected with the sliding blocks in a penetrating andinlaying mode; and sliding grooves are formed in the lower sides of the sliding blocks, wherein sliding rails which are mutually clamped with the sliding grooves are arranged on the upper sides of the side plates. According to the adjustable porous drill jig for the elevator guide rail, the machining problems of the non-standard guide rail with multiple holes, the indefinite hole distance and theindefinite length can be solved.

Description

technical field [0001] The invention relates to the field of elevator guide rails, in particular to an adjustable porous drilling mold for elevator guide rails. Background technique [0002] At present, with the rapid development of high-rise buildings, the use of elevators is becoming more and more extensive. In order to save costs, most elevator factories have begun to produce elevators without machine rooms, so a large number of non-standard guide rails need to be processed. The length of these non-standard guide rails is variable, and a large number of holes need to be processed on it, and the positions of these holes are often inconsistent. Because the longest length of the guide rail is 5m, if a CNC machine tool is used to process these holes, a large machine tool is required. It is very expensive to equip these large CNC machine tools, and it is necessary to configure such a set of CNC equipment for drilling these holes alone. The utilization rate of the equipment is...

Problems solved by technology

[0004] In the daily use of elevator technology, there are many types of drilling jigs, but the structures used and the problems to be solved are different. For example: the technical solution of the patent application No. Rope sheave drilling mold solves the drilling problem of elevator sheave; the technical solution of the patent application number is 201210314290.8, which discloses an elevator rotor yoke drilling mold that uses the drilling mold to quickly finish the elevator motor rotor parts, and solves the problem of elevator rotor Difficult to process; the patent application number is 201120282113.7, which discloses a drilling mold for the elevator counterweight frame, which solves the problem of precision and efficiency of the elevator counterweight frame; There are few public information on the mold technology plan, and the processing difficulty of non-standard guide rails has not been solved

[0005] In this technical field, there is no adjustable porous drilling mold for elevator guide rails, which cannot solve the problem of non-standard guide rail processing with multiple holes, variable hole spacing, and variable length.
