Description

Technical Field

[0001] The present application relates to the technical field of pipe processing, and in particular to a pipe mouth grinding device used for pipe processing. Background Art

[0002] Pipes are materials used to make pipe fittings. Different pipe fittings require different pipes, and the quality of the pipes directly determines the quality of the pipe fittings. In the actual application of pipes, pipe mouth grinding equipment is often used to grind the pipes so that they are more in line with the actual use scenarios and requirements.

[0003] Patent No. CN218904719U discloses a pipe mouth grinding device for PE pipe processing. The pipe mouth grinding device for PE pipe processing rotates two rotating rods so that one end of the rotating rod is fixed in position by a fixed block, and the other end of the rotating rod slides on the slide groove, so that the distance between the two sliding blocks changes, and the distance between the movable bottom plate and the movable top plate is adjusted, so that the movable bottom plate and the movable top plate slide to the two outer sides respectively, and air bags are arranged on the outer side walls of the movable bottom plate and the movable top plate, so that the air bags are fitted with the arc side walls of the PE pipe, so as to achieve the effect of fitting the inner side walls of PE pipes of different diameters, facilitate the rapid fixing of the grinding blade position to grind the PE pipe mouth, and improve the grinding rate of the grinding equipment for pipe mouths of different diameters. However, the device only uses an arc-shaped air bag to fix the pipe being polished, and its fixing range is only half of the pipe surface. During the polishing process, the pipe may be distorted by the high-speed grinding blade, and the qualified rate of the pipe polishing cannot be guaranteed, which increases the cost of pipe polishing and use.

[0023] (III) Beneficial effects

[0024] The present application provides a pipe mouth grinding device for pipe processing. The beneficial effects are as follows:

[0025] 1. The pipe mouth grinding equipment used for pipe processing has a fixing mechanism, and the rotation of the first motor output shaft drives the gear to rotate, the rotation of the gear drives the rack to move, and the movement of the rack drives the arc plate on one side of the connecting rod to move until the rubber pad fits on both sides of the pipe to clamp and fix the pipe, thereby reducing the possibility of the pipe being driven to rotate or shifted by the high-speed grinding disc when grinding the pipe mouth, thereby causing an unqualified grinding effect, and reducing the material cost of grinding the pipe mouth when the pipe is used.

[0026] 2. The pipe mouth grinding equipment used for pipe processing is provided with a waste storage mechanism. When it is necessary to clean the waste, the fixed rod slidably connected to the upper fixed plate is moved upward to disengage it from the fixed hole provided in the lower fixed plate. At the same time, the spring is compressed to pull the lower fixed plate to drive the waste storage box to disengage from the slide slot, so that the waste in the waste storage box can be dumped out, thereby preventing the waste from accumulating inside the equipment after multiple pipe mouth grindings to affect the normal use of the equipment, and reducing the possibility that the accumulated waste enters the joints of the internal parts of the equipment and reduces the service life of the equipment.
