Description

Technical Field

[0001] The invention belongs to the technical field of automobile parts processing, and in particular relates to a surface wear-resistant processing device for automobile metal parts processing. Background Art

[0002] In the processing of automotive metal parts, it is very important to improve the surface wear resistance. Wear-resistant processing can not only extend the service life of automotive parts, but also improve the overall performance and strength of the car and maintain its beauty for a long time. The wear-resistant processing device can perform special treatment on the surface of metal parts to make them have better wear resistance and adapt to various complex working environments.

[0003] The existing surface wear-resistant processing devices for automobile metal parts processing mostly form a protective film on the surface of the metal parts by surface painting or electroplating to improve the wear resistance during the wear-resistant processing. However, during the electroplating processing, the parts to be plated are mostly mounted by a hanger and processed in the electroplating tank. Many automobile parts have porous structures or shaft parts with complex shapes. When processing such parts, the narrow slits are prone to dead corners and bubbles, which will hinder the uniform deposition of metal ions on the surface of the workpiece, resulting in a thinner coating thickness and even plating leakage.

[0004] Based on the above-mentioned situation, we found that it is difficult for the surface wear-resistant processing device of metal parts in the prior art to avoid the above problems at the same time. Therefore, we proposed a surface wear-resistant processing device for automobile metal parts processing, which can discharge bubbles through small-amplitude oscillation, promote the penetration of electroplating liquid into dead corners, and improve the efficiency of automatic material change. Summary of the invention

[0005] The purpose of the present invention is to provide an existing surface wear-resistant processing device for automobile metal parts processing, which has the advantages of discharging bubbles through small-amplitude oscillations, promoting the penetration of electroplating liquid into dead corners, and improving the efficiency of automatic material replacement.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: a surface wear-resistant processing device for automobile metal parts processing, comprising a processing pool, a sub-pool is bolted to the bottom of the processing pool, the front and rear sides of the processing pool are bolted to side plates, the inner side of the side plate is rotatably connected to a connecting shaft, the outer side of the connecting shaft is provided with a processing assembly, the rear side of the front side plate is bolted to a shift block, the front and rear sides of the top of the processing pool are bolted to a sub-frame, the inner side of the sub-frame is rotatably connected to a sub-shaft, the sub-shaft is set to be hollow, the outer side of the sub-shaft is provided with a long groove, the outer side of the sub-shaft is bolted to an arc guide plate, and the outer side of the sub-shaft is bolted to an insulating frame;

[0007] The processing assembly includes a sleeve shaft, the sleeve shaft is bolted to the outside of the connecting shaft, the outside of the sleeve shaft is bolted to a connecting spring, the outside of the connecting spring is bolted to an annular frame, the front side of the annular frame is bolted to a clamping ring, the front side of the clamping ring is clamped to the annular frame, and the outside of the annular frame is bolted to a bracket;

[0008] A mounting plate is clamped on the outer side of the bracket, a conductor block is bolted on the left side of the mounting plate, and a hanger is bolted on the left side of the conductor block.

[0009] The above technical scheme is adopted, by setting up a processing pool as a plating liquid container for electroplating processing, when in use, the side plate supports the connecting shaft, and when the connecting shaft rotates, the processing component on the outside thereof will also rotate with it, the workpiece is mounted on the outside of the hanger, and cooperates with the conductor block, the mounting plate and the bracket to provide current to pass through the parts to be plated, when the connecting shaft rotates slowly, the shift block is stuck on the inner side of the retaining ring, as the sleeve shaft rotates, the connecting spring is deformed, so that the annular frame is misaligned with respect to the sleeve shaft, until the shift block slips off the retaining ring and contacts with another slot of the retaining ring, the connecting spring is reset, so that the annular frame vibrates relative to the sleeve shaft, and the mounting plate and the bracket located inside the processing pool are promoted to vibrate together, so that the plating liquid flows, breaking the static state of the liquid, and the dead corners of the parts to be plated usually have slow or even stopped liquid flow. The flow caused by stagnation and vibration can bring the plating solution into these areas to expel bubbles and completely immerse the parts. When the processing component is always rotating, the secondary shaft in the opposite direction of rotation and the insulating frame on its outside will pick up the mounting plate at the corresponding position on the outside of the bracket and transmit it out of the device. Because it is insulated, it is relatively safe to remove the mounting plate that has completed electroplating. It is also more convenient to connect with the front and rear end transportation equipment, which can improve the degree of automation. The air flow blown into the hollow secondary shaft can be blown out from the inside of the long groove, and the plating solution attached to the surface of the parts can be purged along the guidance of the arc guide plate. When the plating solution drips vertically, it will fall into the arc guide plate and flow back to the processing tank as it rotates, avoiding pollution and difficulty in cleaning caused by falling into the inside of the secondary shaft through the long groove or leaking into the outside of the structure.

[0010] The present invention is further configured as follows: a reduction motor is bolted to the front side of the front side plate, the output end of the reduction motor and the front side of the coupling surface are both bolted to first pulleys, and the two first pulleys are connected via a transmission belt.

[0011] By adopting the above technical solution, a reduction motor is provided for driving the structure, and a first pulley is provided for driving the coupling shaft to rotate.

[0012] The present invention is further configured as follows: the front side of the side plate is rotatably connected to a short shaft, the front side of the outer side of the connecting shaft and the outer side of the short shaft are bolted to gears, the two gears are meshingly connected, the outer side of the short shaft and the surface of the secondary shaft are bolted to a second pulley, and the two second pulleys are connected via a transmission belt.

[0013] By adopting the above technical solution, a short shaft is provided to cooperate with the gear and the second pulley to drive the secondary shaft to rotate through the power of the connecting shaft, and the direction of the structural drive is changed through the meshing of the gears, so that the secondary shaft and the connecting shaft rotate in the opposite direction.

[0014] The present invention is further configured as follows: the front side of the secondary shaft is used in conjunction with the air outlet end of an external fan device, and the top of the mounting plate is provided with two recesses, which are respectively used in conjunction with the bracket and the insulating frame.

[0015] By adopting the above technical solution, an external fan is set up to blow air into the interior of the secondary shaft, so as to blow the liquid on the surface of the mounting plate through the long groove and the arc guide plate. The two recesses can correspond to the bracket and the insulating frame respectively, so as to lift the arc guide plate on the outside of the bracket to the outside of the insulating frame.

[0016] The present invention is further configured as follows: a limiting protrusion is bolted on the surface of the bracket, and the limiting protrusion is used in conjunction with the mounting plate.

[0017] By adopting the above technical solution, by setting the limiting protrusion, the position of the mounting plate can be easily limited to prevent the structure from being greatly displaced or loosened due to vibration.

[0018] The present invention is further configured as follows: a guide rail is bolted to the inner side of the treatment pool, a valve plate is slidably connected to the inner side of the guide rail, a screen frame is clamped to the inner side of the treatment pool, and a filter screen is bolted to the inner side of the screen frame.

[0019] By adopting the above technical solution, by setting the guide rail and the valve plate, when the electroplating liquid needs to be cleaned, the valve plate can be moved up to allow the electroplating liquid to pass through the filter screen to initially filter the internal impurities.

[0020] The present invention is further configured as follows: an electric telescopic cylinder is bolted to the rear side of the treatment pool, a cross frame is bolted to the telescopic end of the electric telescopic cylinder, and the bottom of the cross frame is bolted to the valve plate.

[0021] By adopting the above technical solution, by arranging an electric telescopic cylinder in conjunction with a cross frame, the plate can be lifted and lowered vertically along the guide rail to discharge the electroplating liquid.

[0022] The present invention is further configured as follows: the bottom of the treatment pool and the top of the auxiliary pool are both provided with empty grooves, the inner side of the empty grooves is clamped with the mesh frame, and the bottom of the filter is configured to be arc-shaped.

[0023] By adopting the above technical solution, by setting up empty slots and matching the mesh frame, the electroplating liquid filtered by the filter can be easily put into the treatment pool for standby. The arc-shaped filter can also guide the electroplating liquid flowing through and facilitate the deposition of impurities at the bottom, so that the filter can be easily cleaned when the mesh frame is removed.

[0024] The present invention is further configured as follows: a filter bag is provided on the inner side of the auxiliary pool, a circulation pipe is bolted to the bottom of the right side of the auxiliary pool, and the right side of the circulation pipe is externally connected to a liquid pump.

[0025] By adopting the above technical solution, by setting up filter bags, the plating liquid can be further filtered, and the plating liquid can be pumped out and discharged into a treatment tank for operation or directly discharged for subsequent treatment through an external liquid pump and a circulation pipe.

[0026] The present invention is further configured as follows: a mounting frame is bolted to the inner side of the auxiliary pool, and the inner side of the mounting frame is movably connected to the filter bag.

[0027] By adopting the above technical solution and providing a mounting frame, the filter bag can be easily installed or disassembled, so as to facilitate the replacement or cleaning of the filter bag.

[0028] In summary, the present invention has the following beneficial effects:

[0029] A processing pool is set up as a plating liquid container for electroplating processing. When in use, the side plate supports the connecting shaft, and when the connecting shaft rotates, the processing component on the outside thereof will also rotate with it. The workpiece is mounted on the outside of the hanger, and cooperates with the conductor block, the mounting plate and the bracket to provide current to pass through the parts to be plated. When the connecting shaft rotates slowly, the shift block is stuck on the inner side of the retaining ring. As the sleeve shaft rotates, the connecting spring is deformed, causing the annular frame to be misaligned relative to the sleeve shaft until the shift block slips off the retaining ring and contacts with another slot of the retaining ring. The connecting spring is reset, causing the annular frame to vibrate relative to the sleeve shaft, thereby promoting the mounting plate and the bracket inside the processing pool to vibrate together, causing the plating liquid to flow, breaking the static state of the liquid. The dead corners of the parts to be plated usually have slow liquid flow or even stagnation. The flow brought about can bring the plating liquid into these areas to achieve the effect of expelling bubbles and complete immersion. When the processing component is always rotating, the secondary shaft in the opposite direction of rotation and the insulating frame on its outside will pick up the mounting plate at the corresponding position on the outside of the bracket and transmit it out of the device. Because it is insulated itself, it is relatively safe to remove the mounting plate that has completed electroplating. It is also more convenient to connect with the front and rear end transportation equipment, which can improve the degree of automation. The air flow blown into the hollow secondary shaft can be blown out from the inside of the long groove and the plating liquid attached to the surface of the parts can be blown along the guidance of the arc guide plate. When the plating liquid drips vertically, it will fall into the arc guide plate and flow back to the processing tank as it rotates, avoiding pollution and difficulty in cleaning caused by falling into the inside of the secondary shaft through the long groove or leaking into the outside of the structure.

[0038] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0039] Embodiment 1:

[0040] refer to Figure 1-6 A surface wear-resistant processing device for automobile metal parts processing, comprising a processing pool 1, a sub-pool 2 is bolted to the bottom of the processing pool 1, side plates 3 are bolted to the front and rear sides of the processing pool 1, a connecting shaft 4 is rotatably connected to the inner side of the side plate 3, a processing assembly 5 is arranged on the outer side of the connecting shaft 4, a shift block 6 is bolted to the rear side of the front side plate 3, a sub-frame 7 is bolted to the front and rear sides of the top of the processing pool 1, a sub-shaft 8 is rotatably connected to the inner side of the sub-frame 7, the sub-shaft 8 is arranged to be hollow, a long groove 9 is arranged on the outer side of the sub-shaft 8, an arc guide plate 10 is bolted to the outer side of the sub-shaft 8, and an insulating frame 11 is bolted to the outer side of the sub-shaft 8;

[0041] The processing assembly 5 includes a sleeve shaft 501, which is bolted to the outside of the connecting shaft 4, a connecting spring 502 is bolted to the outside of the sleeve shaft 501, a ring frame 503 is bolted to the outside of the connecting spring 502, a snap ring 504 is bolted to the front side of the ring frame 503, the front side of the snap ring 504 is clamped to the ring frame 503, and a bracket 505 is bolted to the outside of the ring frame 503;

[0042] A mounting plate 12 is clamped on the outer side of the bracket 505, a conductor block 13 is bolted on the left side of the mounting plate 12, and a hanger 14 is bolted on the left side of the conductor block 13;

[0043] By setting the processing pool 1 as a plating liquid container for electroplating processing, the side plate 3 supports the connecting shaft 4 when in use, and when the connecting shaft 4 rotates, the processing component 5 on the outside thereof will also rotate with it. The workpiece is mounted on the outside of the hanger 14, and the conductor block 13, the mounting plate 12 and the bracket 505 are used to provide current to pass through the parts to be plated. When the connecting shaft 4 rotates slowly, the shift block 6 is clamped on the inner side of the clamp ring 504. As the sleeve shaft 501 rotates, the connecting spring 502 is deformed, so that the annular frame 503 is relative to the sleeve shaft 501. The shaft 501 is misaligned until the shift block 6 slips off the retaining ring 504 and contacts the other slot of the retaining ring 504, and the connecting spring 502 is reset, so that the annular frame 503 oscillates relative to the sleeve shaft 501, thereby promoting the mounting plate 12 and the bracket 505 located inside the treatment tank 1 to oscillate together, causing the electroplating liquid to flow, breaking the static state of the liquid. The dead corners of the parts to be plated usually have slow or even stagnant liquid flow, and the flow caused by the oscillation can bring the electroplating liquid into these areas to expel bubbles and achieve the effect of complete immersion.

[0044] like Figure 1 As shown, a reduction motor 15 is bolted to the front side of the front side plate 3, and a first pulley 16 is bolted to the output end of the reduction motor 15 and the front side of the surface of the connecting shaft 4. The two first pulleys 16 are connected by a transmission belt. The reduction motor 15 is set to drive the structure, and the first pulley 16 is set to drive the connecting shaft 4 to rotate.

[0045] like Figure 4 As shown, the surface of the bracket 505 is bolted with a limiting protrusion, and the limiting protrusion and the mounting plate 12 are used in conjunction with each other. By setting the limiting protrusion, the position of the mounting plate 12 can be easily limited to prevent the structure from being displaced significantly or loosening due to vibration.

[0046] Brief description of the use process: When in use, the reduction motor 15 cooperates with the first pulley 16 to drive the connecting shaft 4. When the connecting shaft 4 rotates, the processing component 5 on the outside thereof will also rotate with it. The workpiece is mounted on the outside of the hanger 14, and cooperates with the conductor block 13, the mounting plate 12 and the bracket 505 to provide current to pass through the parts to be plated. When the connecting shaft 4 rotates slowly, the shift block 6 is stuck on the inner side of the retaining ring 504. As the sleeve shaft 501 rotates, the connecting spring 502 is deformed, causing the annular frame 503 to be misaligned relative to the sleeve shaft 501, until the shift block 6 slips off the retaining ring 504 and contacts with another slot of the retaining ring 504, and the connecting spring 502 is reset, causing the annular frame 503 to oscillate relative to the sleeve shaft 501, thereby promoting the mounting plate 12 and the bracket 505 located inside the processing tank 1 to oscillate together, so that the electroplating solution can completely immerse the mounting plate 12 and the parts as much as possible.

[0049] When the processing component 5 is always rotating, the secondary shaft 8 rotating in the opposite direction and the insulating frame 11 on its outside will pick up the mounting plate 12 at the corresponding position on the outside of the bracket 505 and transfer it to the device. Because it is insulated, it is relatively safe to remove the mounting plate 12 that has completed electroplating. It is also more convenient to connect with the front and rear end transportation equipment, which can improve the degree of automation. The air flow blown into the hollow secondary shaft 8 can be blown out from the inside of the long groove 9, and the plating liquid attached to the surface of the parts can be purged along the guidance of the arc guide plate 10. When the plating liquid drips vertically, it will fall into the arc guide plate 10 and flow back to the processing tank 1 as it rotates, avoiding pollution and difficulty in cleaning caused by falling into the inside of the secondary shaft 8 through the long groove 9 or leaking into the outside of the structure.

[0051] like Figure 6 As shown, the front side of the secondary shaft 8 is used in conjunction with the air outlet end of the external fan device, and two recesses are provided on the top of the mounting plate 12, which are respectively used in conjunction with the bracket 505 and the insulating frame 11. By setting up the external fan, air flow can be blown into the interior of the secondary shaft 8, so as to facilitate the blowing of liquid on the surface of the mounting plate 12 through the long groove 9 and the arc guide plate 10. The two recesses can correspond to the bracket 505 and the insulating frame 11 respectively, so as to facilitate the arc guide plate 10 on the outside of the bracket 505 to be lifted to the outside of the insulating frame 11.

[0052] like Figure 1As shown, a guide rail 20 is bolted to the inner side of the treatment tank 1, a valve plate 21 is slidably connected to the inner side of the guide rail 20, a mesh frame 22 is clamped to the inner side of the treatment tank 1, and a filter screen 23 is bolted to the inner side of the mesh frame 22.

[0053] like Figure 1 As shown, an electric telescopic cylinder 24 is bolted to the rear side of the treatment pool 1, and a cross frame 25 is bolted to the telescopic end of the electric telescopic cylinder 24. The bottom of the cross frame 25 is bolted to the valve plate 21. By arranging the electric telescopic cylinder 24 in conjunction with the cross frame 25, the valve plate can be lifted and lowered vertically along the guide rail 20 to discharge the electroplating liquid.

[0054] like Figure 2 As shown, both the bottom of the treatment tank 1 and the top of the auxiliary tank 2 are provided with an empty groove 26, the inner side of the empty groove 26 is engaged with the mesh frame 22, and the bottom of the filter screen 23 is set to be arc-shaped. By setting the empty groove 26 to cooperate with the mesh frame 22, the electroplating liquid filtered by the filter screen 23 can be conveniently allowed to enter the treatment tank 1 for standby use. The arc-shaped filter screen 23 can also guide the electroplating liquid flowing through and facilitate the deposition of impurities at the bottom, so that the filter screen 23 can be easily cleaned when the mesh frame 22 is taken out.

[0055] like Figure 2 As shown, a filter bag 27 is provided on the inner side of the auxiliary tank 2, and a circulation pipe 28 is bolted to the bottom of the right side of the auxiliary tank 2. An external liquid pump is connected to the right side of the circulation pipe 28. By setting the filter bag 27, the plating liquid can be further filtered, and the plating liquid can be extracted and discharged into the treatment tank 1 for operation or directly discharged for subsequent treatment through the external liquid pump and the circulation pipe 28.

[0056] like Figure 2 As shown, a mounting frame 29 is bolted to the inner side of the auxiliary pool 2, and the inner side of the mounting frame 29 is movably connected to the filter bag 27. By setting the mounting frame 29, the filter bag 27 can be easily installed or disassembled, so as to facilitate the replacement or cleaning of the filter bag 27.
