A simple lifting platform

Abstract

A simple lifting platform belongs to the technical field of product heat treatment platforms, and in particular relates to a simple lifting platform for product heat treatment. The invention provides a simple lifting platform which is simple in structure, stable and reliable, and can realize vertical and lateral movement. The invention includes a base, on which two groove-shaped columns are arranged, and a crossbeam is arranged between the top ends of the two groove-shaped columns. A slider matching the groove is provided; the slider is connected to the vertical side of the same L-shaped lifting frame; a lead screw is arranged under the beam, and a screw nut is arranged on the lead screw, and a connecting screw is arranged on the screw nut. frame, the vertical side of the L-shaped lifting frame is provided with a connecting groove that matches the connecting frame; the horizontal side of the lifting frame is provided with a horizontal slide plate, and the horizontal slide plate is provided with a rotating gear; the lifting frame A toothed rack cooperating with the rotating gear is arranged on the horizontal side of the frame.

Description

technical field [0001] The invention belongs to the technical field of product heat treatment platforms, and in particular relates to a simple lifting platform for product heat treatment. Background technique [0002] Some product parts require the workpiece to move up and down at a constant and low speed during the heat treatment process. The existing lifting mechanism for heat treatment of the workpiece usually uses a simple screw nut mechanism. It is necessary to manually turn the screw nut to realize the lifting of the workpiece, and the lateral movement of the workpiece cannot be realized. Inconvenient to use, resulting in poor product heat treatment quality. [0003] In addition, since the screw nut is directly connected to the stage, and the heat-treated workpiece is usually heavy in weight, this causes the screw to be subjected to a large radial force, which seriously affects the service life of the screw. And if the workpiece that needs heat treatment is too heavy...

Problems solved by technology

It is necessary to manually turn the screw nut to realize the lifting of the workpiece, and the lateral movement of the workpiece cannot be realized

Inconvenient to use, resulting in poor product heat treatment quality

[0003] In addition, due to the direct connection between the screw nut and the stage, the heat-treated workpiece is usually heavy, which causes the screw to be subjected to a large radial force, which seriously affects the service life of the screw

However, if the weight of the workpiece to be heat treated is too large, the ordinary lifting mechanism cannot be used.

[0004] There are also some lifting platforms in other fields. For example, the patent number is 201010131872.3, and the name is the invention patent of "lifting platform", which provides a lifting platform for lifting goods in stores. This lifting platform cannot realize the lateral movement of workpieces. , In addition, the structure of this lifting platform is unreasonable. It realizes the movement of the lifting platform through the cooperation of the gear and the rack. The teeth of the gear and the rack are the main stress-bearing parts. If the workpiece is heavy, the teeth may break, causing the workpiece to be damaged. fall, dangerous
