Description

Technical Field

[0001] This application belongs to the field of clamping tooling technology, specifically a thermal spraying clamping tooling. Background Technology

[0002] Thermal spraying clamping fixtures (also known as spraying fixtures, tooling fixtures or positioning fixtures) are key auxiliary equipment in the thermal spraying process. Their core function is to securely, accurately and efficiently fix the workpiece to be sprayed, and to ensure the uniformity, consistency and repeatability of the coating.

[0003] Existing thermal spraying clamping fixtures are fixed installations, which cannot be rotated during thermal spraying. When spraying irregularly shaped parts, repeated position adjustments and re-clamping are required, resulting in a decrease in overall work efficiency. Now, a thermal spraying clamping fixture is provided that can rotate the clamped material, reduce position adjustment time, and improve work efficiency. Utility Model Content

[0006] By adopting the above technical solution, when using this device, after determining the clamping of the material, the operator turns on the servo motor. The servo motor is connected to an external power source via wires to convert mechanical energy into electrical energy, which drives the drive gear to rotate. The drive gear and the driven gear mesh with each other, driving the drive shaft to rotate. The protective plate connected to the end of the drive shaft drives the clamping plate and the bidirectional lead screw connected to the clamping plate to rotate. The rotation direction is the same as the direction of the drive shaft, causing the clamped material to rotate in a circle.

The drive gear 15 meshes with the driven gear 16 to drive the drive shaft to rotate. The protective plate 8 connected to the end of the drive shaft drives the clamping plate 19 and the bidirectional lead screw 20 connected to the clamping plate 19 to rotate.

[0035] The implementation principle of a thermal spraying clamping fixture embodiment of this application is as follows: When clamping materials, the operator starts the drive motor 13, which drives the worm 12 to rotate. The worm wheel 24 meshes with the worm 12, and the rotation of the worm 12 drives the worm wheel 24 to rotate. The clamping gear 23 is coaxially connected to the worm wheel 24, and the clamping gear 23 drives the knurled sleeve 21 to move back and forth. Through the knurled sleeve 21, the connecting gear 25 is driven to rotate. When the knurled sleeve 21 moves towards the clamping plate 19, the distance between the two clamping plates 19 will increase. When the knurled sleeve 21 moves towards the drive motor 13, the distance between the two clamping plates 19 will decrease, thus clamping materials of different sizes.

[0036] When using this device, after the material is clamped, the operator turns on the servo motor 14.
