Description

Technical Field

[0001] This utility model relates to the field of chromium plating technology, specifically to a chromium plating clamping device for a screw pump shaft. Background Technology

[0002] Chromium plating is a process of electroplating a thin layer of chromium onto a metal surface. By forming a dense chromium layer on the surface of metal workpieces such as screw pump shafts, drive shafts, agitator shafts, and compressor shafts, the hardness and wear resistance of the workpieces can be effectively improved. During the chromium plating process of screw pump shafts, the screw pump shaft needs to be kept stable so that the electroplating solution can evenly cover its surface. Therefore, a clamping device is required to clamp the screw pump shaft.

[0003] However, existing screw pump shaft chrome plating clamping devices have simple structures, lack a structure to drive the clamping components to move up and down, and do not have the function of chrome plating the connection between the screw pump shaft and the clamping components, resulting in poor chrome plating effect. Therefore, we propose a screw pump shaft chrome plating clamping device. Summary of the Invention

[0004] To address the problems in the prior art, this utility model provides a chrome-plated clamping device for a screw pump shaft. This novel chrome-plated clamping device for a screw pump shaft has a structure that drives the clamping component to move up and down, and facilitates chrome plating at the connection between the screw pump shaft and the clamping component, thereby effectively improving the chrome plating effect.

[0005] The technical solution adopted by this utility model to solve its technical problem is a chrome plating clamping device for a screw pump shaft, including a chrome plating pool, a drive assembly and a clamping plate. A mounting frame is provided on the top of the chrome plating pool, and a drive assembly is installed on the top of the mounting frame. The drive assembly includes an electric push rod, a connecting rod, a clamping sleeve and a knob bolt. The electric push rod is installed on the top of the mounting frame, and a clamping sleeve is provided at the lower end of the mounting frame. A connecting rod is connected to the top of the clamping sleeve. A through hole is provided on the mounting frame, and the top of the connecting rod passes through the through hole and connects to the output end of the electric push rod.

[0006] Both sides of the clamping sleeve are provided with knob bolts through bolt holes. The clamping sleeve has an internal cavity, and a clamping plate is provided inside the cavity. The outer side of the clamping plate is connected to the end of the knob bolt. A flexible pad is provided on the inner side of the clamping plate. A screw pump shaft is provided at the lower end of the clamping sleeve.

[0007] By adopting the above technical solution, the new screw pump shaft chrome plating clamping device has a structure that drives the clamping component to move up and down, and facilitates chrome plating at the connection between the screw pump shaft and the clamping component, thereby effectively improving the chrome plating effect.

[0008] Specifically, the top of the chrome plating pool has a No. 1 L-shaped bracket and a No. 2 L-shaped bracket on each side, and a limit ring is provided between the No. 1 L-shaped bracket and the No. 2 L-shaped bracket.

[0009] By adopting the above technical solution, the No. 1 L-shaped bracket and the No. 2 L-shaped bracket can be supported by the limiting ring. When the screw pump shaft moves down, the lower end of the screw pump shaft can pass through the limiting ring, and thus the limiting ring can limit the screw pump shaft.

[0010] Specifically, an inlet pipe is provided at the upper end of one side of the chromium plating bath through an inlet port.

[0011] Specifically, a drain pipe is provided at the bottom of one end of the chrome plating pool through a drain outlet, and a drain valve is provided on the drain pipe.

[0012] Specifically, the flexible pad is made of polyurethane foam material.

[0013] By adopting the above technical solution, the flexible liner made of polyurethane foam material has good liquid absorption and liquid retention performance, and can effectively absorb and store chromium plating liquid. The porous structure inside the flexible liner helps to evenly transfer the chromium plating liquid to the surface of the screw pump shaft.

[0014] The beneficial effects of this utility model are:

[0015] The chrome-plated clamping device for a screw pump shaft described in this utility model allows personnel to tighten the knob bolts to force the flexible pad to fit tightly against the outer wall of the screw pump shaft, thereby achieving the purpose of clamping the screw pump shaft from the upper end. The electric push rod can drive the clamping sleeve and the screw pump shaft to move downwards via the connecting rod, thus achieving the purpose of moving the screw pump shaft downwards without the need for manual movement of the screw pump shaft.

[0016] The present invention discloses a chrome plating clamping device for a screw pump shaft. The chrome plating liquid can penetrate into the cavity inside the clamping sleeve. The flexible pad can absorb the chrome plating liquid and evenly transfer the chrome plating liquid to the surface of the screw pump shaft, thereby chrome plating the connection between the screw pump shaft and the clamping component.

[0017] The present invention provides a chrome-plating clamping device for a screw pump shaft, wherein the limiting ring can limit the lower end of the screw pump shaft, preventing the screw pump shaft from shaking significantly during the chrome plating process. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] To improve the effect of chrome plating, such as Figure 1-4 As shown, the present invention discloses a chrome plating clamping device for a screw pump shaft, comprising a chrome plating pool 1, a drive assembly 3, and a clamping plate 8. A mounting frame 2 is provided on the top of the chrome plating pool 1, and the drive assembly 3 is mounted on the top of the mounting frame 2. The drive assembly 3 includes an electric push rod 301, a connecting rod 302, a clamping sleeve 303, and a knob bolt 304. The electric push rod 301 is mounted on the top of the mounting frame 2, and the clamping sleeve 303 is provided at the lower end of the mounting frame 2. The connecting rod 302 is connected to the top of the clamping sleeve 303. A through hole 10 is provided on the mounting frame 2, and the top of the connecting rod 302 passes through the through hole 10 and connects to the output end of the electric push rod 301.

[0026] Both sides of the clamping sleeve 303 are provided with knob bolts 304 through bolt holes. The clamping sleeve 303 has a cavity 7 inside, and a clamping plate 8 is provided inside the cavity 7. The outer side of the clamping plate 8 is connected to the end of the knob bolt 304. A flexible pad 9 is provided on the inner side of the clamping plate 8. A screw pump shaft 4 is provided at the lower end of the clamping sleeve 303.

[0027] In use, by tightening the knob bolt 304, the flexible gasket 9 can be made to fit tightly against the outer wall of the screw pump shaft 4, thereby achieving the purpose of clamping the screw pump shaft 4 from the upper end. The electric push rod 301 can drive the clamping sleeve 303 and the screw pump shaft 4 to move downward through the connecting rod 302, thereby achieving the purpose of driving the screw pump shaft 4 downward, so that the personnel do not need to move the screw pump shaft 4 manually.

[0028] The limiting ring 16 can limit the lower end of the screw pump shaft 4 to prevent the screw pump shaft 4 from shaking significantly during the chrome plating process.

[0029] The chromium plating solution can penetrate into the cavity 7 inside the clamping sleeve 303. The flexible pad 9 can absorb the chromium plating solution and evenly transfer it to the surface of the screw pump shaft 4, thus chromium plating can be performed on the connection between the screw pump shaft 4 and the clamping component.

[0030] For example, such as Figure 1 As shown, the top of the chrome plating pool 1 has a first L-shaped bracket 14 and a second L-shaped bracket 15 on both sides, and a limit ring 16 is provided between the first L-shaped bracket 14 and the second L-shaped bracket 15.

[0031] In use, L-shaped bracket 14 and L-shaped bracket 15 can be supported by limiting ring 16. When the screw pump shaft 4 moves down, the lower end of the screw pump shaft 4 can pass through the limiting ring 16, and thus the limiting ring 16 can limit the screw pump shaft 4.

[0032] For example, such as Figure 1 , Figure 4 As shown, an inlet pipe 13 is provided at the upper end of one side of the chromium plating pool 1 through an inlet port 12.

[0033] During use, personnel can inject the chromium plating solution into the chromium plating bath 1 through the liquid inlet pipe 13.

[0034] For example, such as Figure 1 , Figure 4 As shown, a drain pipe 5 is provided at the bottom of one end of the chrome plating pool 1 through a drain outlet 11, and a drain valve 6 is provided on the drain pipe 5.

[0035] When in use, personnel can open the drain valve 6 on the drain pipe 5 to clamp and discharge the chromium plating liquid inside the chromium plating tank 1.

[0036] For example, such as Figure 3 As shown, the flexible pad 9 is made of polyurethane foam material.

[0037] When in use, the flexible gasket 9 made of polyurethane foam has good liquid absorption and retention properties, and can effectively absorb and store chromium plating liquid. The porous structure inside the flexible gasket 9 helps to evenly transfer the chromium plating liquid to the surface of the screw pump shaft 4.

[0038] In use, the operator places the screw pump shaft 4 to be chrome-plated at the lower end of the clamping sleeve 303 in the drive assembly 3, inserts the upper end of the screw pump shaft 4 into the clamping sleeve 303, and tightens the knob bolt 304. This drives the clamping plate 8 to move with the flexible pad 9 towards the screw pump shaft 4, so that the flexible pad 9 can fit tightly against the outer wall of the screw pump shaft 4, thereby achieving the purpose of clamping the screw pump shaft 4 from the upper end.

[0039] Furthermore, personnel inject chromium plating solution into the chromium plating tank 1 through the liquid inlet pipe 13. The electric push rod 301 in the drive assembly 3 can then drive the clamping sleeve 303 and the screw pump shaft 4 to move downwards via the connecting rod 302. The lower end of the screw pump shaft 4 passes through the limiting ring 16, which can limit the lower end of the screw pump shaft 4 to prevent the screw pump shaft 4 from shaking significantly during the chromium plating process. The screw pump shaft 4 is immersed in the chromium plating solution inside the chromium plating tank 1, and the screw pump shaft 4 can then be chromium plated.

[0040] Furthermore, when the clamping sleeve 303 and the screw pump shaft 4 are immersed in the chromium plating solution, the chromium plating solution penetrates into the cavity 7 inside the clamping sleeve 303. The flexible pad 9 can absorb the chromium plating solution and at the same time can evenly transfer the chromium plating solution to the surface of the screw pump shaft 4, so that the connection between the screw pump shaft 4 and the clamping component can be chromium plating.

[0041] Furthermore, personnel can open the drain valve 6 on the drain pipe 5 to clamp and discharge the chromium plating solution inside the chromium plating pool 1.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
