Horizontal pipe fixing device for machining

Abstract

The invention discloses a horizontal pipe fixing device for machining. The horizontal pipe fixing device comprises a base, wherein a stepping motor is fixedly connected to the base, two first mountingbases are symmetrically and fixedly connected to the base, the two first mounting bases are fixedly connected to the outer side wall of the stepping motor, and threaded shafts are rotationally connected in the first mounting bases. According to the horizontal pipe fixing device, by means of forward and reverse rotation of the stepping motor, the threaded shafts are driven to rotate through movable gears, then a water tank is driven to move up and down in the vertical direction, the water pressure in a guide pipe is controlled by controlling the height of the water tank, so that the clamping force of a fixing mold for clamping a pipe is controlled, the clamping force of the fixing mold on the pipe is controllable, and can be automatically adjusted according to the material and the force bearing performance of the pipe to be machined, and as a result, the problem that the pipe is extruded and deformed due to the fact that the clamping force is too large can be effectively solved, and the problem that clamping is not firm due to the fact that the clamping force is too small can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a horizontal pipe fixing device for mechanical processing. Background technique [0002] Pipe is a material that is often used in the process of mechanical processing and manufacturing. In order to meet the needs of use, processes such as cutting and punching are often performed on its surface. In order to ensure the processing accuracy and quality of the pipe, at the same time to ensure In order to ensure the safety during production, it is necessary to clamp and fix the pipe to be processed before processing. [0003] At present, the clamping and fixing of pipes is usually realized by using V-shaped clamps, but the contact area between the V-shaped clamps and the pipes is very small, and a good clamping and fixing of the pipes requires a relatively large clamping force, so it is easy The sag of the pipe is caused by the excessive pressure of the contact part. If ...

Problems solved by technology

[0004] The purpose of the present invention is to solve the shortcomings in the prior art, such as: the clamping and fixing of pipes is usually realized by using V-shaped clamps at present, but the contact area between the V-shaped clamps and pipes is very small, and the pipes Good clamping and fixing requires relatively large clamping force, so it is easy to cause the pipe to sag due to excessive pressure on the contact part. If the clamping force on the pipe is reduced, the maximum static friction force of the contact part between the clamp and the pipe will be too The small size makes the pipe easy to rotate during processing, which seriously affects the quality of pipe processing
