Cutting torch lifting mechanism of cutting machine

Abstract

The invention relates to a cutting torch lifting mechanism of a cutting machine. The cutting torch lifting mechanism comprises a frame, a connecting plate, a screw rod, a speed reducer, a linear guide rail, a telescopic dustproof cover, a transitional rod and a cutting torch, wherein the parts are not connected with the frame; the upper end of the screw rod is mounted with a gasket; the lower end of the screw rod penetrates through the frame and is suspended on the frame; the driving device is connected to the screw rod; one end of the connecting plate is connected with the driving device; the other end of the connecting plate is connected with the upper end of the linear guide rail; the lower end of the guide rail penetrates through the bottom of the frame; a guide rail slide bock is mounted at the bottom of the longitudinal inner wall of the frame; the lower end of the guide rail is connected with one end of the transitional rod; the other end of the transitional rod is connected with the cutting torch; the telescopic dustproof cover is sleeved outside the linear guide rail outside the frame; and travel limiters are arranged at upper and lower ends of the longitudinal inner wall of the frame. The cutting torch lifting mechanism of the cutting machine, provided by the invention, has the advantages of small structure, low cost, anti-collision performance, convenience in operation and greater safety and reliability in use and can be manually adjusted; a cutting nozzle and other parts of the cutting torch can be protected; the cutting quality is improved; and the lifting precision and stability are guaranteed.

Description

technical field [0001] The invention relates to an industrial cutting device, in particular to a cutting torch lifting mechanism of a cutting machine. technical background [0002] In today's industrial field, welded structural parts have been widely used in various industries. Plate cutting is the first step in the process of welding finished products, and it is also an important process to ensure the quality of welding. The use of advanced modern cutting technology can not only ensure the welding quality of products and improve labor productivity, but also greatly reduce the manufacturing cost of enterprise products and shorten the product production cycle. With the wide application of new products, new processes and new technologies. Intelligent precision cutting will become the future development trend of the cutting industry. Intelligent precision cutting technology can not only ensure the welding quality of products and improve labor productivity, but also greatly r...

AI Technical Summary

Problems solved by technology

[0006] 1. The existing technology uses two linear guide rails, and the width of the lifting device is relatively large, generally 200mm. When cutting two torches at the same time, the minimum cutting width cannot be less than 200mm

In addition, the use of two guide rails also means that the cost is high

[0007] 2. The existing technology does not have an anti-collision device, and the lifting mechanism generally only has a limit switch at the upper and lower limit positions of the stroke.

Light collisions are easy to damage the cutting nozzle of the torch and affect the quality of cutting, while heavy collisions can damage screw rods, nuts or other parts

[0008] 3. The existing technology can only be adjusted by motor, and there is no manual adjustment function

Inconvenient for debugging and use
