Description

Technical Field

[0001] The utility model relates to the technical field of thermal spraying, in particular to a material rotary clamping mechanism for thermal spraying. Background Art

[0002] Thermal spraying refers to heating and melting a coating material, atomizing it into extremely fine particles with a high-speed air flow, and spraying it onto the surface of a workpiece at a very high speed to form a coating. Currently, when performing thermal spraying on materials, generally, the material is first clamped by a clamping device and then sprayed.

[0003] However, the existing material clamping devices do not have a rotation function. Therefore, when performing thermal spraying operations on some shaft-like materials, serious uneven spraying will occur on their surfaces. Therefore, we propose a material rotary clamping mechanism for thermal spraying. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a material rotary clamping mechanism for thermal spraying.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A material rotary clamping mechanism for thermal spraying includes a material clamping table, a rotary clamping mechanism, and a height adjustment mechanism. The rotary clamping mechanism includes a rotary drive assembly, a fixed seat fixedly connected to the top outer wall of the material clamping table, a drive shaft rotatably installed on the fixed seat, a first mounting disk coaxially and fixedly connected to one end outer wall of the drive shaft, and a first three-jaw chuck coaxially and fixedly connected to the side wall of the first mounting disk.

[0007] The rotary drive assembly includes a support plate fixedly connected to one side outer wall of the fixed seat, a drive motor fixedly installed on the side wall of the support plate, a worm fixedly sleeved on the output shaft of the drive motor, and a worm gear fixedly sleeved on the drive shaft and meshing with the worm.

[0008] As a preferred technical solution, the rotary clamping mechanism further includes a chute opened on the top of the material clamping table, an adjustment screw rotatably installed in the chute, an adjustment seat threadedly connected to the adjustment screw, a rotary shaft rotatably installed on the adjustment seat, a second mounting disk coaxially and fixedly connected to one end outer wall of the rotary shaft, and a second three-jaw chuck coaxially and fixedly connected to the side wall of the second mounting disk.

[0009] As a preferred technical solution, the outer wall of the adjustment seat is slidably connected to the inner wall of the chute, and a handwheel is fixedly connected to one end outer wall of the adjustment screw.

[0010] As a preferred technical solution, the height adjustment mechanism includes a bearing guide rail, a double-acting cylinder fixedly installed on the outer wall of the top of the bearing guide rail, two sliding blocks sequentially fixed on the two piston rods of the double-acting cylinder, and two linkage inclined rods sequentially hinged on the tops of the two sliding blocks.

[0011] As a preferred technical solution, both of the two sliding blocks are slidably connected to the bearing guide rail.

[0012] As a preferred technical solution, the tops of the two linkage inclined rods are both hinged to the bottom of the material clamping table, and the two linkage inclined rods are arranged in a cross and non-contact manner.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. By rotating the adjusting screw rod, the present utility model controls the adjusting seat threadedly connected thereto to perform linear motion, so that the distance between the first three-jaw chuck and the second three-jaw chuck can be flexibly adjusted, thereby facilitating the stable clamping of shaft-like materials of different specifications and improving the adaptability.

[0015] 2. After the shaft-like material is clamped, the present utility model controls the worm to rotate by driving the motor, and then the worm gear meshing with the worm controls the driving shaft to rotate, so as to rotate the shaft-like material, so that its surface can be evenly sprayed during the thermal spraying operation, improving the thermal spraying effect on the surface of the material.

[0016] 3. The present utility model is provided with a height adjustment mechanism. By the telescopic movement of the two piston rods of the double-acting cylinder, the two sliding blocks are controlled to approach or move away from each other, and then the two linkage inclined rods arranged in a cross and non-contact manner control the material clamping table to perform lifting motion, so that the processing height of the material clamped on the material clamping table can be flexibly adjusted, better meeting different use requirements during the thermal spraying operation.
