Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

As shown in fig. 1 to 6, the plasma cladding processing base of the present embodiment includes a base body 1, a clamping block 2, a synchronous turntable 6 and a handle 3. At least three sliding grooves 13 are uniformly distributed on the base body 1, the sliding grooves 13 are arranged along the radial direction of the base body 1, a through hole 4 for clamping and fixing is formed in the middle of the base body 1, for example, a clamping jaw of a three-jaw chuck can be used for hooking the through hole 4, and the clamping jaw is driven to be far away from and clamp and fix the base body 1. The clamping block 2 comprises at least three blocks which can slide in the sliding groove 13. In order to limit the clamping block 2 to be positioned in the sliding groove 13, guide rails 14 are arranged on the side walls of the two sides of the sliding groove 13, guide grooves 12 are arranged on the two sides of the clamping block 2, and the guide grooves 12 can be slidably matched with the guide rails 14, so that the clamping block 2 can only slide along the guide rails 14 and cannot move up and down to be separated from the sliding groove 13.

The clamping block 2 is driven through a synchronous rotary table 6, specifically, a transmission tooth 10 is arranged on the lower end face of the clamping block 2, the synchronous rotary table 6 is arranged at the lower end of the clamping block 2, a spiral tooth groove 11 is arranged on the upper end face of the synchronous rotary table 6, the transmission tooth 10 is connected with the tooth groove 11 in a matched mode, the transmission tooth 10 comprises a plurality of arranged at intervals, a certain radian is achieved, the transmission tooth can be arranged in the spiral tooth groove 11, and the clamping block 2 can be synchronously close to or far away from through rotating the synchronous rotary table 6.

In order to facilitate clamping of workpieces of different sizes and shapes, the clamping block 2 is L-shaped, so that the clamping block 2 can clamp the outer surface of the workpiece, the clamping block 2 can also be hooked on the inner surface of the workpiece, the upper end of the clamping block 2 is provided with a baffle rod 5 for clamping and fixing the workpiece to be machined, when the workpiece is large in size, the workpiece can be clamped between the baffle rods 5, the baffle rods 5 can be cylindrical, and line contact is realized between the baffle rods 5 and the workpiece, so that damage to the surface of the workpiece is reduced.
