Detailed implementation manners

[0024] The following further describes the present application in detail with reference to the Figures 1-4 accompanying drawings of the specification.

[0025] A cathode head CNC tooling disclosed in an embodiment of the present application includes a fixed seat 1, a mounting plate 2 located above the fixed seat 1, two first clamping rods 3 fixed to the mounting plate 2, and profiling clamping units 4 arranged at intervals on the mounting plate 2. Among them, in the embodiment of the present application, there are two profiling clamping units 4, and they are arranged at intervals along the length direction of the first clamping rod 3. When in use, the profiling clamping unit 4 and the first clamping rod 3 are used to clamp the cathode head.

[0026] Specifically, the first clamping rod 3 is provided with a first profiling groove 31. The profiling clamping unit 4 includes a second clamping rod 41 located between the two first clamping rods 3, two limiting rods 42 passing through the first clamping rod 3 and the second clamping rod 41, and a limiting block 43 for restricting the sliding of the second clamping rod 41. Among them, the second clamping rod 41 is provided with a second profiling groove 411 communicating with the first profiling groove 31, and the first profiling groove 31 and the second profiling groove 411 are used to place and clamp the cathode head. In addition, when the second clamping rod 41 is clamped, there is a spacing between the second clamping rod 41 and the mounting plate 2, that is, the second clamping rod 41 is located directly above the mounting plate 2.

[0027] The limiting block 43 is located between the two second clamping rods 41. At the same time, the limiting block 43 is also located between the two limiting rods 42. A cushion block is fixed to the top of the mounting plate 2 for the detachable connection of the limiting block 43. The cushion block is fixed to the limiting block 43 through a bolt, and the cushion block is fixed to the mounting plate 2 through a bolt.

[0028] A fixing member is provided between the limiting rod 42 and the first clamping rod 3. The fixing member is a locking bolt 5 passing through the first clamping rod 3, and the locking bolt 5 is threadedly connected to the limiting rod 42.

[0029] Further, three fixing blocks 6 are fixedly arranged at intervals on the top of the fixed seat 1 for the fixed connection of the mounting plate 2, so that the fixing blocks 6 are located between the fixed seat 1 and the mounting plate 2.

[0030] Further, a holding rod 7 is installed on the top of the mounting plate 2 near the wide side of the mounting plate 2, which is convenient for manual taking.

[0031] Further, the mounting plate 2 is provided with an outer diameter positioning and clamping structure 8 at intervals for clamping the cathode head and providing different clamping methods. The outer diameter positioning and clamping structure 8 includes a fixing column 81 fixed to the top of the mounting plate 2, a locking sleeve 82 fixed to the top of the fixing column 81, a support bolt 83 threadedly connected to the top of the fixing column 81, and a tightening sleeve 84 threadedly connected to the outer wall of the fixing column 81. Among them, the locking sleeve 82 is made of plastic or rubber material and has a certain deformation ability and elasticity. The top of the locking sleeve 82 is provided with telescopic grooves 821 at intervals so that when the collecting sleeve moves downward, it forces the locking sleeve 82 to tighten, thereby locking the cathode head.

[0032] The bolt head of the support bolt 83 is completely accommodated in the locking sleeve 82 for the cathode head to be placed. The top of the tightening sleeve 84 has a necked-down structure. The locking sleeve 82 is located inside the tightening sleeve 84. By using the threaded connection relationship between the collecting sleeve and the fixing column 81, when the tightening sleeve 84 is driven downward, the top opening of the locking sleeve 82 shrinks, thereby clamping the cathode head. In addition, in order to facilitate the rotation of the tightening sleeve 84, the outer wall of the tightening sleeve 84 is provided with rotation grooves 841 at intervals for a wrench to be inserted to drive the tightening sleeve 84 to rotate.

[0033] The implementation principle of a cathode head CNC tooling in an embodiment of the present application is as follows:

[0034] Before processing, first place the cathode head in the groove formed by splicing the first profiling groove 31 and the second profiling groove 411. Using the profiling principle, the second clamping rod 41, the limiting block 43, and the limiting rod 42 apply a clamping force to the side of the cathode head for clamping and locking. This can not only ensure that the tooling can closely fit the cathode head to achieve stable and accurate clamping, but also can be adapted to the clamping of cathode heads with different sizes and shapes. Moreover, this tooling can clamp multiple cathode heads for processing at one time, thereby improving work efficiency.

[0035] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
