[0017] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the drawings and specific implementation methods of the specification. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0018] like Figure 1 , Figure 2 A horizontal super-long rod electroplating fixture shown includes a conductive sleeve 1 and a workpiece sleeve 2. The conductive sleeve 1 is a cylindrical structure, and a conductive rod 3 is installed in the conductive sleeve 1. Two threaded holes penetrating the conductive sleeve 1 are provided on the side of the conductive sleeve 1, and fasteners 4 are installed in the threaded holes. The fasteners 4 are used to lock the conductive rod 3 in the conductive sleeve 2. Preferably, a groove 11 is provided on the inner wall of the conductive sleeve 1, and the groove 11 extends along the axial direction of the conductive sleeve 1, and the groove 11 is located at the lower end of the threaded hole. A buffer pad 12 is installed in the groove 11, and the fastener 4 abuts against the conductive rod 3 through the buffer pad 12 to prevent the conductive rod 3 from being compressed and deformed and affecting the disassembly of the fixture.

[0019] like Figure 1 , Figure 2As shown, the workpiece sleeve 2 is coaxially installed on the right end of the conductive sleeve 1, and the workpiece sleeve 2 includes a lower sleeve 21 and an upper sleeve 22. The lower sleeve 21 and the upper sleeve 22 are both semi-tube-shaped. The lower sleeve 21 is fixed on the right end of the conductive sleeve 1, and the upper sleeve 22 is detachably connected to the lower sleeve 21 through a connecting piece 5, so that the workpiece 7 is clamped in the workpiece sleeve 2.

[0020] Preferably, a step is fixed to the right end of the workpiece sleeve 2, and a connecting portion 71 matching the inner wall of the workpiece sleeve 2 is fixed to the left end of the workpiece 7. The cooperation between the connecting portion 71 and the step prevents the workpiece 7 from axial movement. A threaded hole penetrating the upper sleeve 22 is provided on the side of the upper sleeve 22, and an anti-rotation member 6 is installed in the threaded hole. The anti-rotation member 6 abuts against the workpiece 7 to prevent the workpiece 7 from rotating relative to the workpiece sleeve 2.

[0021] The conductive sleeve 1 and the workpiece sleeve 2 are made of 45# steel through lathe processing and wire cutting to ensure the strength of the electroplating fixture. The fastener 4, the connecting piece 5 and the anti-rotation piece 6 are all A2-80 bolts to ensure the reliability and detachability of the bolts.

[0022] When in use, the workpiece 7 is first hoisted and placed on the lower shaft sleeve 21, and then the upper shaft sleeve 22 and the lower shaft sleeve 21 are locked to fix the workpiece 7; when disassembling, the upper shaft sleeve 22 is first removed, and then the workpiece 7 is hoisted away, thereby greatly reducing the difficulty of loading and unloading and improving production efficiency.

[0023] The technical solution provided in the embodiments of the present application has at least the following technical effects or advantages:

[0024] 1. The workpiece is connected to the workpiece through the workpiece sleeve, which increases the conductive area, effectively overcomes the problem of excessive current burning the product, and ensures the quality of the product;

[0025] 2. The workpiece is fixed by a detachable workpiece sleeve, which facilitates the installation and disassembly of the workpiece, improves production efficiency and reduces production costs.
