Description

TECHNICAL FIELD

[0001] The present application relates to a sand blasting equipment, more particularly to a back pipe clamping device of a target material sand blasting equipment. BACKGROUND

[0002] At present, the production and manufacturing of target materials need to use the production process of plasma spraying. Before plasma spraying, the target material back pipe needs to be sand blasted to remove dust, oil stains and other attachments on the surface, and the surface needs to reach a certain roughness.

[0003] In the prior art, the target material back pipe is clamped on the clamping device, and the sand blasting gun is installed on the walking mechanism. When sand blasting, the target material back pipe rotates axially at a certain speed, and the sand blasting gun reciprocates along the radial direction of the target material back pipe to make the surface of the target material back pipe be sand blasted. For example, the utility model patent with the patent number CN222038168U discloses a target material sand blasting equipment, wherein it is specifically described that the walking control assembly comprises a walking motor slidingly connected to the inner side wall of the walking frame, a planetary reducer is installed above the walking motor, and a walking gear is installed above the planetary reducer; a walking tooth row is installed on the inner side wall of the walking frame, and one side surface of the walking tooth row is in meshing connection with the walking gear. Then, the walking control assembly is started, the walking motor in the walking control assembly cooperates with the planetary reducer to drive the walking gear to rotate at a reduced speed, and because the walking gear is in meshing connection with the fixedly installed walking tooth row, the walking gear drives the fixed plate to slide and walk to the left on the walking frame. At this time, the fixed plate drives the sand blasting gun and the sand blasting gun to move to the left and perform sand blasting work.

A chain wheel transmission part 204 is installed on one side of one of the driving suspension frames 202, and the chain wheel transmission part 204 is used to drive the chain wheel part 203. The traction assembly includes a first walking support 205 and a supporting guide rail 206. The supporting guide rail 206 is installed on both sides of the inner wall of the sand blasting preparation equipment 1 to support the first walking support 205.

The operation of loosening the target backing pipe 3 is contrary. The clamping part two 2103 and the clamping part one 2106 are both movable pins, and the directions of the sharp corners of the two movable pins are opposite.

[0049] On the basis of the above embodiment, the positioning device is installed on the second walking support 208, and the positioning device cooperates with the first walking support 205 to position the second walking support 208. By adjusting the position of the second walking support 208, the distance between the fixed clamp and the movable clamp is changed, so that the target backing pipe 3 with different lengths is adapted, and the position of the second walking support 208 is fixed through the positioning device, so that the equipment adaptability is improved.
