Description

Technical Field

[0001] The utility model relates to the technical field related to electroplating equipment, in particular to an integrated tooling fixture for electroplating the inner bore of an aluminum alloy cylinder body. Background Art

[0002] With the continuous development of the economy, the demand for engines is increasing, and at the same time, the performance requirements for engine cylinders are becoming more and more stringent. The inner wall of the piston hole of the engine will cause severe friction due to the movement of the piston, which will cause wear of the inner wall of the piston hole for a long time, making the engine unable to use normally. Therefore, the inner wall of the piston hole of the cylinder is generally electroplated with chrome to improve the wear resistance of the inner wall of the piston hole and increase the service life of the cylinder.

[0003] At present, when chromium is electroplated on the inner wall of the piston hole of the cylinder body, since only the inner wall of the piston hole needs to be electroplated, in order to avoid waste of liquid medicine, the remaining surfaces of the cylinder body need to be sealed. At present, most of the cylinder body is wrapped with sealing tape, and then the inner wall of the piston hole is exposed, and then the cylinder body is electroplated. Although this can meet the electroplating requirements, the operation is very time-consuming and labor-intensive, and the work efficiency is extremely low. If the cylinder body is not wrapped, on the one hand, the liquid medicine will be wasted, and on the other hand, the liquid medicine will corrode the surface of the cylinder body, affecting the overall strength of the cylinder body.

[0039] Example:

[0040] Reference Figure 1-Figure 12 As shown, an integrated tooling fixture for electroplating inner holes of an aluminum alloy cylinder body comprises a base 1, a mounting frame 2 is arranged on the base 1, a clamping assembly is arranged on the top of the mounting frame 2, and a positioning assembly 6 is arranged in the middle corresponding to the position of the clamping assembly;

[0041] Reference Figure 3 As shown, the positioning assembly 6 includes a positioning plate 3, a liquid inlet seat 4 is clamped on the positioning plate 3, a plating hole 401 connected to the piston hole of the cylinder body to be electroplated is opened on the liquid inlet seat 4, a guide block 9 is clamped in the plating hole 401, an anode positioning rod 8 is provided on the guide block 9, an anode positioning rod 8 is sleeved with an anode tube 7, the cylinder body to be electroplated is placed on the liquid inlet seat 4, a water surrounding jacket 5 is placed above the cylinder body to be electroplated, the water surrounding jacket 5 is pressed on the cylinder body to be electroplated by a clamping assembly, the anode tube 7 is located in the water surrounding jacket 5, and the horizontal position of the top end of the anode tube 7 is lower than the horizontal position of the top end of the water surrounding jacket 5;

[0042] A liquid inlet hole 402 is provided at the bottom of the side of the liquid inlet seat 4 , and the liquid inlet hole 402 is connected to the electroplating hole 401 .

[0043] The liquid inlet seat 4 is installed and supported by the positioning plate 3, and the cylinder body to be electroplated is supported by the liquid inlet seat 4, and then the water surrounding jacket 5 is placed on the cylinder body to be electroplated, and the liquid inlet seat 4, the cylinder body to be electroplated and the water surrounding jacket 5 are pressed and fixed into a whole by the clamping assembly.

[0044] The guide block 9 can fix the position of the anode positioning rod 8 and thus position the anode tube 7, and can also facilitate the liquid medicine entering through the liquid inlet hole 402 to enter the cylinder to be electroplated.

[0045] The horizontal position of the top of the anode tube 7 is lower than that of the top of the water jacket 5, so that the liquid medicine flows into the anode tube 7 from the top of the anode tube 7 and then is discharged, while the water jacket 5 is used to prevent the liquid medicine from leaking from the top.

[0046] When in use, the cylinder body to be electroplated is placed on the liquid inlet seat 4, and then the surrounding water jacket 5 is placed on the cylinder body to be electroplated, and then the surrounding water jacket 5 is compressed by the clamping assembly, so that the positions of the liquid inlet seat 4, the cylinder body to be electroplated and the surrounding water jacket 5 are fixed, and then the liquid inlet hole 402 is connected to the liquid source, the anode tube 7 is connected to the anode, and the cylinder body to be electroplated is connected to the cathode, and the liquid enters the electroplating hole 401 in the liquid inlet seat 4 from the liquid inlet hole 402, and the liquid level of the liquid in the electroplating hole 401 rises, and then enters the piston hole of the cylinder body to be electroplated through the guide block 9. Since the electrodes are connected, chromium will be electroplated on the inner wall of the piston hole of the cylinder body to be electroplated, and the liquid level of the liquid will continue to rise and reach the surrounding water jacket 5. The liquid level of the liquid in the surrounding water jacket 5 continues to rise. When the liquid level reaches the top of the anode tube 7, it flows into the inside of the anode tube 7 from the top of the anode tube 7, and then flows into the anode positioning rod 8 from the anode tube 7, and the liquid can be discharged from the fixture.

[0047] Reference Figure 4 , 5 As shown in Figure 6, the guide block 9 includes a positioning sleeve 902 and a guide plate 903. The guide plate 903 is fixedly provided on the outer wall of one end of the positioning sleeve 902, and the end of the positioning sleeve 902 is flush with the surface of the guide plate 903. The guide plate 903 is evenly provided with guide holes 901.

[0048] The anode positioning rod 8 is positioned by the positioning sleeve 902, and the anode positioning rod 8 is clamped inside the positioning sleeve 902, and the guide block 9 is clamped in the electroplating hole 401 of the liquid inlet seat 4 through the guide plate 903. The side wall of the guide plate 903 abuts against the inner wall of the electroplating hole 401, so that the position of the anode positioning rod 8 is fixed, and the guide block 9 on the guide plate 903 allows the liquid to pass through. After the liquid enters the electroplating hole 401 from the bottom of the electroplating hole 401, as the liquid level rises, the liquid passes through the guide hole 901 and reaches the piston hole of the cylinder body to be electroplated.

[0049] A positioning pin 14 corresponding to the mounting hole on the surface of the cylinder body to be electroplated is vertically provided on the upper surface of the liquid inlet seat 4.

[0050] The cylinder body to be electroplated is supported and positioned by the positioning pin 14. On the one hand, it ensures the stability of the position of the cylinder body being pressed and fixed. On the other hand, it is convenient for workers to install the cylinder body to be electroplated. They only need to match the positioning pin 14 with the mounting block 601 on the surface of the cylinder body to be electroplated, which reduces the difficulty of the workers' work and improves their work efficiency.

[0051] A shielding ring rubber sleeve 12 is arranged around the electroplated hole 401 on the upper surface of the liquid inlet seat 4 .

[0052] The shielding ring rubber sleeve 12 ensures the sealing between the liquid inlet seat 4 and the cylinder to be electroplated, preventing the liquid from leaking from the gap, which would cause uneven electroplating on the inner wall of the cylinder, and also avoids environmental pollution caused by the leaked liquid.

[0053] A centering sleeve 13 is arranged between the bottom surface of the water surrounding jacket 5 and the cylinder body to be electroplated, and a through hole is opened inside the water surrounding jacket 5 to connect with the piston hole of the cylinder body to be electroplated.

[0054] The centering sleeve 13 improves the sealing performance between the water surrounding jacket 5 and the cylinder body to be electroplated and ensures that when the water surrounding jacket 5 is placed, the through hole on the water surrounding jacket 5 can be aligned with the piston hole of the cylinder body to be electroplated.

[0055] The anode positioning rod 8 is arranged in the positioning sleeve 902, and the anode tube 7 is sleeved on the top end thereof.

[0056] The anode positioning rod 8 is positioned by the positioning sleeve 902 , and the anode tube 7 is positioned by the anode positioning rod 8 .

[0057] The bottom end of the anode positioning rod 8 passes through the liquid inlet seat 4 and is connected to an extension tube 11 .

[0058] The extension tube 11 is conveniently connected to the drain pipe to drain the liquid flowing out of the middle of the anode tube 7 into the liquid pool.

[0059] The pressing assembly comprises a mounting block 601 , on which a presser 602 is arranged, and at the end of the presser 602 a pressing piece is arranged.

[0060] The mounting block 601 facilitates the installation of the clamp 602 on the mounting frame 2, and the clamping piece at the end of the clamp 602 clamps the water jacket 5. The clamp 602 drives the clamping piece to move up and down, thereby clamping the water jacket 5 on the cylinder body to be electroplated, or loosening the water jacket 5 to replace the cylinder body.

[0061] The clamping member includes a clamping block 603 and a connecting rod 604 . The connecting rod 604 is vertically arranged in the middle of one side of the clamping block 603 . One end of the connecting rod 604 is fixedly connected to the clamping block 603 , and the other end is threadedly connected to the end of the clamp 602 .

[0062] The pressing block 603 is conveniently connected to the pressing device 602 through the connecting rod 604, and the pressing block 603 increases the contact area with the water surrounding jacket 5, thereby ensuring the structural stability of pressing the water surrounding jacket 5.

[0063] The mounting frame 2 is independently provided with a foot cup 10 , and the mounting frame 2 is arranged on the base 1 through the foot cup 10 . A clearance groove is arranged on the base 1 at a position corresponding to the extension tube 11 .

[0064] The height of the mounting frame 2 can be easily adjusted by the foot cup 10, so that the positioning plate 3, the liquid inlet seat 4 and the water surrounding jacket 5 on the mounting frame 2 are in a horizontal position, ensuring uniform electroplating inside the piston hole of the cylinder body, thereby ensuring product quality.

[0065] When in use, first adjust the foot cup 10 so that the liquid inlet seat 4 is in a horizontal state, then lift the clamp 602 to make the clamping block 603 rise, place the cylinder body to be electroplated on the liquid inlet seat 4, and at the same time make the mounting hole on the surface of the cylinder body cooperate with the positioning pin 14 to complete the positioning of the cylinder body, and then place the water jacket 5 on the cylinder body to be electroplated so that the through hole on the water jacket 5 is aligned with the piston hole of the cylinder body, and then use the clamp 602 to clamp the clamping block 603 on the water jacket 5, and then the water jacket 5, the cylinder body to be electroplated and the liquid inlet seat 4 are clamped and fixed, and the clamping and fixation of the cylinder body to be electroplated is completed.

[0066] During electroplating, the liquid inlet hole 402 of the liquid inlet seat 4 is connected to the liquid medicine pool through the liquid inlet tube, the extension tube 11 is connected to the liquid medicine pool through the infusion tube, the cathode is connected to the cathode through the clamp, and the anode tube 7 is connected to the anode through the clamp, and the inner wall of the piston hole of the cylinder body can be electroplated with chromium. During the electroplating process, the liquid medicine continuously enters from the liquid inlet hole 402, flows into the inside of the anode tube 7 from the top of the anode tube 7, and is then discharged from the extension tube 11 and refluxed to the liquid medicine pool. The liquid medicine circulates in the fixture to ensure that the inner wall of the piston hole of the cylinder body is evenly electroplated, thereby improving the quality of the cylinder body.

[0067] In actual use, the top side wall of the water surrounding jacket 5 is grooved to facilitate the connection of the anode tube 7 in the water surrounding jacket 5 to the anode.

[0068] A portion of the side wall of the anode tube 7 located inside the water surrounding jacket 5 is opened to facilitate the flow of chemical solution into the anode tube 7 .

[0069] According to the number of piston holes on the cylinder body to be electroplated, the number of electroplating holes 401 is set on the liquid inlet seat 4 and the number of through holes on the water surrounding jacket 5, and the anode tube 7 in each electroplating hole 401 is connected to the anode respectively, so that the inner walls of multiple piston holes on the cylinder body can be electroplated with chrome at the same time, further improving work efficiency.

[0070] A tee, a cross or other connecting pipe fittings can be set on the base 1 according to the number of piston holes on the cylinder body, which is used to connect with multiple liquid inlet holes 402, so that the infusion volume of each liquid inlet hole 402 is the same, thereby ensuring uniform electroplating of the inner walls of the multiple piston holes on the cylinder body and improving product quality.

[0071] The clamp 602 adopts the Jiagang CH36204 clamp.

[0072] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited to them. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model; in the absence of conflicts, the embodiments of the utility model and the features in the embodiments can be combined with each other.
