Description

Technical Field

[0001] This invention relates to the field of housing surface treatment technology, specifically to a surface treatment device for an aluminum alloy housing of a fan clutch. Background Technology

[0002] A fan clutch is a device used for automatic cooling of a car engine. The housing of this device is usually made of aluminum alloy. After the aluminum alloy housing of the fan clutch is manufactured, a coating is usually applied to its surface to protect the aluminum alloy surface.

[0003] The existing patent, CN217973400U, discloses a "surface treatment device for high-precision aluminum alloy shells", which includes an immersion tank and a motor output shaft. Multiple elastic sleeves are fixedly connected to the front and rear sides of the immersion tank, and multiple auxiliary elastic sleeves are fixedly connected to both sides of the immersion tank. A guide tube is fixedly sleeved on the outside of the immersion tank. The solution is transported to various parts inside the immersion tank through the cooperation of parts such as an electric push rod, a pressure plate, a vertical box, a guide tube, multiple auxiliary elastic sleeves, and multiple elastic sleeves.

[0004] This patent application uses a linkage structure to spray the liquid medicine from multiple elastic sleeves to different positions within the soaking tank, achieving a thorough mixing effect between the medicine and the solution. The trigger condition for the moving pressure plate to press down is achieved by a set of T-shaped plates pressing against its upper surface. However, in actual use, the following problems arise:

[0005] 1. The T-shaped plate can only press one corner of the upper surface of the movable pressure plate, which will cause uneven force on the upper surface of the movable pressure plate, so it cannot be pressed down horizontally, and may even cause the movable pressure plate to get stuck inside the guide tube;

[0006] 2. After the movable pressure plate is pressed down to the bottom of the guide tube, the pressure makes it difficult for the movable pressure plate to return to its original position, thus making it impossible to continue subsequent continuous operations.

[0007] Therefore, in response to the problems mentioned above, it is necessary to develop a surface treatment device for the aluminum alloy housing of a fan clutch. Summary of the Invention

[0008] The purpose of this invention is to provide a surface treatment device for the aluminum alloy housing of a fan clutch, which solves the problems of unreasonable force structure of the moving pressure plate and difficulty in resetting the subsequent linkage structure in existing housing surface treatment devices, thus hindering the normal use of subsequent devices.

[0031] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings.

[0032] Combination Figures 1-3 and Figure 4 A surface treatment device for an aluminum alloy housing of a fan clutch includes an immersion tank body 3, a guide channel 4 fixedly installed on the outer surface of the immersion tank body 3, a liquid storage tank body 1 fixedly installed on one side of the guide channel 4, and a control component 2 fixedly installed on the upper end of the liquid storage tank body 1. An elastic sleeve 31 is provided on the inner side of the immersion tank body 3, and a U-shaped pressure plate 43 is movably installed on the inner side of the guide channel 4. The guide channel 4 covers the outer side of the elastic sleeve 31. The control component 2 includes a telescopic cylinder 21 fixedly installed on the upper part of the liquid storage tank body 1, and an inverted U-shaped block 23 fixedly connected to the output end of the telescopic cylinder 21. A hydraulic component 5 is fixedly installed on the upper surface of the guide channel 4.

[0033] The present invention will be further described below with reference to embodiments.

[0034] Please see Figures 2-7 An oil reservoir 51 is fixedly installed on the upper surface of the guide channel 4. A compression piston plate 52 is movably installed on the upper inner side of the oil reservoir 51. Two sets of first hydraulic pipes 53 are connected to both sides of the oil reservoir 51. One end of the first hydraulic pipe 53 is connected to a second hydraulic pipe 54. Each end of the second hydraulic pipe 54 is connected to a set of hydraulic telescopic rods 55. The four sets of hydraulic telescopic rods 55 are fixedly installed at the four corners of the upper surface of the guide channel 4. The telescopic ends of the hydraulic telescopic rods 55 movably penetrate the guide channel 4. The upper surface is fixedly connected to the upper surface of the U-shaped pressure plate 43. The oil storage tank 51 is fixedly installed below the inverted U-shaped block 23. The inner side of the oil storage tank 51 stores hydraulic oil. The bottom end of the liquid storage tank body 1 is connected to the infusion pipe 11. The infusion pipe 11 is connected to the inner side of the liquid storage tank body 1. A one-way valve is provided between the infusion pipe 11 and the liquid storage tank body 1. The one-way valve allows the infusion pipe 11 to be connected to the bottom of the inner side of the liquid storage tank body 1 in one direction. The infusion pipe 11 is used to inject medicine into the inner side of the liquid storage tank body 1.

[0035] A liquid outlet groove 12 is provided on the lower end wall of the liquid storage tank body 1. A pressing component 13 is slidably installed on the upper inner side of the liquid storage tank body 1. The lower surface of the liquid outlet groove 12 is flush with the bottom of the liquid storage tank body 1. A piston block 133 is slidably connected to the inner side of the liquid storage tank body 1. An inclined rubber pad 134 is fixedly connected to the lower end of the piston block 133. A guide rod 131 is fixedly connected to the upper end of the piston block 133. A spring A132 is sleeved on the surface of the guide rod 131. The inclined rubber pad 134... 4. The lower, wider portion is away from the side where the liquid outlet tank 12 is located. A connecting block 22 is fixedly connected to the output end of the lower end of the telescopic cylinder 21. A through hole 25 is opened on the surface of the connecting block 22, penetrating both the upper and lower surfaces of the connecting block 22. An inverted U-shaped block 23 is fixedly connected to one side of the connecting block 22. An anti-detachment block A135 is fixedly connected to the top of the guide rod 131. The guide rod 131 is movably positioned inside the through hole 25. The spring A132 is located below the connecting block 22. The anti-detachment block A1... The setting of 35 is used to prevent the guide rod 131 from detaching from the inside of the through hole 25. When the inside of the liquid storage tank body 1 is filled with medicine, the connecting block 22 is pushed downward by controlling the telescopic cylinder 21. The connecting block 22 can then push the piston block 133 downward by the spring A132, thereby squeezing the medicine inside the liquid storage tank body 1 and causing the medicine to be discharged from the outlet groove 12 opened at the bottom of the liquid storage tank body 1. When the inclined rubber pad 134 moves to the bottom of the liquid storage tank body 1 and makes initial contact, as the piston block 133 continues to press down, the lower inclined surface of the inclined rubber pad 134 deforms and gradually comes into contact with the bottom surface of the liquid storage tank body 1 from left to right. In this way, the medicine remaining at the bottom of the liquid storage tank body 1 can be driven from left to right to the position of the outlet groove 12, forming a guide for the medicine, thereby ensuring that the medicine inside the liquid storage tank body 1 can be fully output through the outlet groove 12 and improving the utilization rate of the medicine.

[0036] A fitting block 24 is fixedly connected to the lower end of one side of the inverted U-shaped block 23. A truncated pyramid 56 is fixedly connected to the middle of the upper surface of the extrusion piston plate 52. A pressure block 57 is fixedly connected to the middle of the upper end of the truncated pyramid 56. A fitting groove 58 is provided on the upper surface of the pressure block 57. The pressure block 57 is located directly below the fitting block 24. The fitting block 24 slides into the inner side of the fitting groove 58. When the telescopic cylinder 21 pushes the piston block 133 to the bottom of the liquid storage tank body 1 through the connecting block 22 and the spring A132, the connecting block 22 will spring back as the connecting block 22 continues to press down. Spring A132 is compressed, causing connecting block 22 to drive inverted U-shaped block 23 to move downward a certain distance. During this movement, fitting block 24 will fit into the inner side of fitting groove 58. Then, the prism 56 pushes the extrusion piston plate 52 to move downward inside the oil tank 51, thereby pushing the hydraulic oil in the oil tank 51 to be output to the first hydraulic pipe 53. The prism 56, pressure block 57 and fitting block 24 are movably fitted, which allows inverted U-shaped block 23 to steadily push extrusion piston plate 52 downward.

[0037] One end of the first hydraulic pipe 53 is connected to the middle of the second hydraulic pipe 54. The hydraulic oil in the oil tank 51 is input to the four sets of hydraulic telescopic rods 55 through the first hydraulic pipe 53 and the second hydraulic pipe 54. Since one end of the first hydraulic pipe 53 is connected to the middle of the second hydraulic pipe 54, the hydraulic oil flows to the four sets of hydraulic telescopic rods 55 with the same path length. Therefore, the telescopic ends of the four sets of hydraulic telescopic rods 55 can push the U-shaped pressure plate 43 downward synchronously. Since the hydraulic telescopic rods 55 are evenly distributed on the four corners of the upper surface of the guide groove 4, the four sets of hydraulic telescopic rods 55 can push the U-shaped pressure plate 43 horizontally downward.

[0038] A lower outer cover 41 is fixedly installed on the outer side of the soaking tank body 3. An upper sealing plate 42 is fixedly installed on the upper end of the lower outer cover 41. The inner ring of the upper sealing plate 42 is fixedly connected to the outer wall of the soaking tank body 3. A liquid inlet groove 411 is opened on one side surface of the lower outer cover 41. The liquid inlet groove 411 is connected to the liquid outlet groove 12. The oil storage tank 51 and the hydraulic telescopic rod 55 are both fixedly installed on the upper surface of the upper sealing plate 42. The telescopic end of the hydraulic telescopic rod 55 moves through the piston plate 52 to its lower surface. The liquid output from the liquid outlet groove 12 of the liquid storage tank body 1 enters the inner side of the lower outer cover 41 through the liquid inlet groove 411. Under the continuous downward pressure of the piston block 133, it is evenly sprayed onto the inner side of the soaking tank body 3 through the elastic sleeve 31. After the piston block 133 is pressed to the bottom, the remaining liquid in the lower outer cover 41 is sprayed out by the squeezing action of the U-shaped pressure plate 43.

[0039] The lower surface of the U-shaped pressure plate 43 is provided with a U-shaped inclined rubber pad 431. One side of the lower surface of the U-shaped inclined rubber pad 431 is provided with a through groove 432. The through groove 432 is opened on the side near the liquid inlet groove 411. With the U-shaped inclined rubber pad 431, according to the principle of the inclined rubber pad 134 mentioned above, the lower edge of the U-shaped inclined rubber pad 431 can first contact the bottom of the lower outer cover 41 during the pressing of the U-shaped pressure plate 43. Then, as the U-shaped pressure plate 43 presses down, the U-shaped inclined rubber pad 431 deforms, squeezing the remaining liquid medicine at the bottom of the lower outer cover 41 from the outside to the inside, forming a guide for the liquid medicine, so that the liquid medicine can be discharged more efficiently through the elastic sleeve 31.

[0040] Four sets of pull columns 421 are evenly distributed and movably installed on the upper surface of the upper sealing plate 42. The pull columns 421 movably penetrate the upper and lower surfaces of the upper sealing plate 42. A spring B422 is sleeved on the outer surface of the pull column 421 at the upper end of the upper sealing plate 42. An anti-detachment block B423 is fixedly connected to the top of the pull column 421. The spring B422 has the elastic potential energy of expansion. One end of the infusion tube 11 is connected to a liquid pump. Through the operation of the liquid pump, the liquid medicine is injected into the inside of the liquid storage tank body 1 through the infusion tube 11. The liquid medicine will push the inclined rubber pad 134 to move upward. The liquid medicine will also flow through the groove 432 to The lower surface of the inclined rubber pad 431 pushes the inclined pressure plate 43 upward. The spring B422 pushes the anti-detachment block B423 to drive the pull column 421 to assist in raising the inclined pressure plate 43. During the process, the inclined pressure plate 43 will return to the top inside the lower outer cover 41, and the hydraulic oil inside the hydraulic telescopic rod 55 will also return to the inside of the oil tank 51 under the reverse squeezing action of its telescopic end, in preparation for subsequent work. In this way, by injecting the liquid, the piston block 133, the inclined pressure plate 43, and even the hydraulic oil inside the oil tank 51 and the squeeze piston plate 52 can be automatically reset.

[0041] In addition, the injection of medicine into the inside of the storage tank body 1 can also be achieved by actively controlling the piston block 133 to move upward, so that a negative pressure is formed in the closed cavity inside the storage tank body 1, thereby allowing the infusion tube 11 to actively draw the medicine into the inside of the storage tank body 1, thus eliminating the need for the participation of a liquid pump.
