Description

Technical Field

[0001] This utility model relates to the technical field of valve stem electroplating, and in particular to a tooling for controlling the plating thickness of valve stem electroplating with a step. Background Technology

[0002] The valve stem is an important component of a valve, used for transmission. It connects to the actuator or handle at the top and directly drives the valve core to move or rotate, thereby realizing the valve's opening and closing or regulating function. When manufacturing the valve stem, it needs to be electroplated. At this time, a plating thickness control fixture is required to control the plating thickness.

[0003] Currently, traditional coating thickness control fixtures, when used to control the thickness of electroplated coatings on valve stems, often result in poor electroplating effects due to their incompatibility with valve stem specifications. This fails to meet the electroplating requirements of valve stems of different specifications, necessitating reinforcement and readjustment by staff. This not only increases workload but also affects electroplating efficiency. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to provide a step-type valve stem electroplating coating thickness control fixture. By setting up an adjustment mechanism, precise control of the coating thickness during the valve stem electroplating process is achieved. The combined use of the first cylinder and the second cylinder can flexibly adjust the position of the step plate, thereby adapting to the electroplating requirements of valve stems of different specifications.

[0006] To achieve the above objectives, the first aspect of this utility model proposes a plating thickness control fixture for electroplating valve stems with steps, comprising: a control fixture and an adjustment mechanism, wherein the adjustment mechanism includes a first cylinder, a second cylinder and a step plate, wherein the first cylinder is mounted on the control fixture, the second cylinder is connected to the output end of the first cylinder, and the step plate is connected to the output end of the second cylinder.

[0008] Specifically, the control fixture is equipped with a fixed block, a buffer block is provided on the outer wall of the fixed block, a guide head is provided on the outer wall of the fixed block, and a bolt block is provided on the outer wall of the fixed block.

[0009] Specifically, ventilation holes are provided on the step slab.

[0010] Specifically, a fixing plate is installed on the step slab.

[0011] Specifically, a clamping mechanism is provided on the fixed plate. The clamping mechanism includes an electric slide, a support block, a spring, and a clamping block.

[0013] Compared with the prior art, the present invention has the following advantages: The present invention provides a stepped valve stem electroplating coating thickness control fixture, which achieves precise control of coating thickness during valve stem electroplating through the setting of the adjustment mechanism. The combined use of the first cylinder and the second cylinder can flexibly adjust the position of the stepped plate to adapt to the electroplating requirements of valve stems of different specifications.

[0021] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] The following description, with reference to the accompanying drawings, describes a step-type electroplating coating thickness control fixture for valve stems according to an embodiment of the present invention.

[0023] like Figures 1-4 As shown in the figure, a step-type valve stem electroplating coating thickness control fixture according to an embodiment of the present invention includes: a control fixture 1 and an adjustment mechanism 2, wherein the adjustment mechanism 2 includes a first cylinder 21, a second cylinder 22 and a step plate 23, wherein the first cylinder 21 is disposed on the control fixture 1, the second cylinder 22 is connected to the output end of the first cylinder 21, and the step plate 23 is connected to the output end of the second cylinder 22.

[0024] The control fixture 1 is provided with a fixing block 24, a buffer block 25 is provided on the outer wall of the fixing block 24, a guide head 26 is provided on the outer wall of the fixing block 24, and a bolt block 27 is provided on the outer wall of the fixing block 24.

[0025] Specifically, before controlling the coating thickness of the valve stem, the valve stem is first placed on the step plate 23. Then, the second cylinder 22 moves the step plate 23, causing one end of the valve stem to contact the buffer block 25. The buffer block 25 buffers the valve stem, preventing it from colliding directly with the fixed block 24 and damaging the valve stem surface, thus affecting its use. At the same time, the guide head 26 guides the valve stem, making its movement more stable and preventing it from shifting. Furthermore, the bolt block 27 facilitates the installation and disassembly of the control fixture 1, thereby improving the efficiency of the workers.

[0026] In one embodiment of this application, such as Figure 1 As shown, ventilation holes 3 are provided on the step plate 23.

[0027] Understandably, the vent hole 3 facilitates ventilation of the valve stem on the stepped plate 23, preventing surface defects caused by lack of ventilation during the electroplating process and further improving the electroplating quality of the valve stem.

[0028] In one embodiment of this application, such as Figure 1 As shown, a fixing plate 4 is provided on the step plate 23.

[0029] Understandably, the mounting plate 4 facilitates the fixation of the valve stem, preventing it from shaking during electroplating and thus improving the electroplating efficiency of the valve stem.

[0030] In one embodiment of this application, such as Figure 1 and Figure 4 As shown, a clamping mechanism 5 is provided on the fixed plate 4. The clamping mechanism 5 includes an electric slide 51, a support block 52, a spring 54, and a clamping block 55. The electric slide 51 is provided on the fixed plate 4. The support block 52 is connected to the moving block of the electric slide 51. A slot 53 is provided on the outer wall of the support block 52. The spring 54 is provided inside the slot 53. The clamping block 55 is connected to the other end of the spring 54.

[0031] Specifically, when the valve stem needs to be clamped, the operator starts the electric slide table 51. The electric slide table 51 drives the support block 52 to move, the support block 52 drives the slot 53 to move, the slot 53 drives the spring 54 to move, and the spring 54 drives the clamping block 55 to move, so that the two clamping blocks 55 clamp and fix the valve stem. The spring 54 increases the friction between the clamping block 55 and the valve stem, making the clamping block 55 clamp the valve stem more firmly and further improving the stability of the valve stem during the electroplating process.

[0032] In one embodiment of this application, such as Figure 1 As shown, the control fixture 1 is equipped with a locking component 6.

[0033] Understandably, the locking element 6 facilitates locking the control fixture 1, preventing it from shaking during the electroplating process and further improving the quality of the valve stem electroplating.

[0034] Working principle: Before controlling the coating thickness of the valve stem, the valve stem is first placed on the stepped plate 23. Then, the second cylinder 22 moves the stepped plate 23, causing one end of the valve stem to contact the buffer block 25. The buffer block 25 buffers the valve stem, preventing it from colliding directly with the fixed block 24 and damaging the valve stem surface, thus affecting its use. Simultaneously, the guide head 26 guides the valve stem, making its movement more stable and preventing deviation. Furthermore, the bolt block 27 facilitates operation. The control fixture 1 is used for installation and disassembly, thereby improving the work efficiency of the staff. When it is necessary to clamp the valve stem, the staff starts the electric slide table 51. The electric slide table 51 drives the support block 52 to move. The support block 52 drives the slot 53 to move. The slot 53 drives the spring 54 to move. The spring 54 drives the clamping block 55 to move, so that the two clamping blocks 55 clamp and fix the valve stem. The setting of the spring 54 increases the friction between the clamping block 55 and the valve stem, making the clamping block 55 clamp the valve stem more firmly, and further improving the stability of the valve stem during the electroplating process.
