Description

Technical Field

[0001] This invention relates to the field of elevator guide rail electroplating technology, specifically to an electroplating device for elevator guide rail production. Background Technology

[0002] Elevator guide rails are elevator components made of steel rails and connecting plates. They are divided into car guide rails and counterweight guide rails, and are classified into three types according to their cross-sectional shape: T-shaped, L-shaped, and hollow. While playing a guiding role, the guide rails also bear the impact forces during car and elevator braking, as well as the impact forces during emergency braking of the safety brake. The magnitude of these forces is related to the elevator's load capacity and speed. Therefore, the guide rails should be selected according to the elevator's speed and load capacity. The car guide rails are usually called the main rails, and the counterweight guide rails are called the auxiliary rails. Electroplating equipment is required in the production process of elevator guide rails.

[0003] Chinese Patent CN112872975B discloses a surface treatment system for electroplated workpieces, including a frame, a conveying device for transporting the electroplated workpieces, a clamping device for holding the workpieces, and a grinding device on the frame. The grinding device includes a grinding wheel for grinding the workpieces and a drive component for rotating the grinding wheel. A dustproof box for protecting against dust generated during the grinding process is mounted on the frame. The drive component is mounted on the dustproof box, and the grinding wheel is mounted on the output shaft of the drive component. During grinding, both the grinding wheel and the workpiece are within the dustproof box. This application effectively reduces manual labor intensity and minimizes the risk of workers absorbing dust, thus reducing adverse health effects.

[0004] However, the above-mentioned patent has the following shortcomings: When the above-mentioned patent clamps the workpiece with a clamping plate and inserts the metal workpiece into the electroplating bath, the electroplating bath can achieve plating of most areas of the surface of the metal workpiece. However, the area of ​​the metal workpiece that contacts the clamping plate is blocked by the clamping plate, and the electroplating solution in the electroplating bath cannot effectively enter. As a result, it is impossible to effectively electroplat these parts, or the plating effect on these parts is poor, which reduces the plating area and plating effect of the metal workpiece. Therefore, it needs to be improved. Summary of the Invention

[0005] The purpose of this invention is to provide an electroplating apparatus for elevator guide rail production, so as to solve the problems mentioned in the background art.

[0013] As a further aspect of the present invention: damping plates are installed on both sides of the clamping hole, and the damping plates are used to increase the resistance to the workpiece.

[0014] By adopting the above technical solution, the stability of the workpiece inserted into the clamping hole is increased.

[0015] As a further aspect of the present invention: the stirring assembly includes a mounting plate, a drive shaft is rotatably mounted laterally inside the lifting frame, and a second gear is mounted at the end of the drive shaft outside the lifting frame. The mounting plate is rotatably mounted in the middle of the lifting frame, and multiple stirring bodies are rotatably mounted on the mounting plate. A first bevel gear is mounted on the top of each stirring body, and a second bevel gear meshes with the outside of each first bevel gear. The second bevel gears are all mounted on the drive shaft. A second toothed plate is vertically mounted inside the electroplating tank, and the second toothed plate is used to drive the second gears.

[0016] By adopting the above technical solution, the electroplating solution is stirred, which increases the uniformity of metal ions in the electroplating solution.

[0017] As a further aspect of the present invention: the workstation adjustment component includes a rectangular hole, which is opened through the top of the frame, and a lead screw is rotatably installed in the rectangular hole. A threaded block is threaded on the outer side of the lead screw, and a motor is installed on the outer wall of the frame, which is used to drive the lead screw to rotate.

[0018] By adopting the above technical solution, the position of the lifting frame can be adjusted, which facilitates loading and unloading of materials inside the lifting frame.

[0019] As a further embodiment of the present invention: a first electric push rod is vertically installed through the top of the threaded block, and a connecting body is installed at the output end of the first electric push rod. The bottom of the connecting body is installed on the top of the lifting frame, and guide columns are vertically symmetrically installed on the top of the connecting body, with the tops of the guide columns sliding through the threaded block.

[0021] As a further aspect of the present invention: the cleaning assembly includes a moving plate, a second electric push rod is installed through the U-shaped frame, the output end of the second electric push rod is equipped with the moving plate, and a plurality of scraping holes are opened through the moving plate.

[0022] By adopting the above technical solution, the electroplating solution on the electroplated workpiece can be cleaned.

[0023] As a further aspect of the present invention: guide plates are installed on both sides of the scraper hole at the bottom of the moving plate, and the guide plates are installed at an angle.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows: The electroplating device for elevator guide rail production is equipped with a drive rod, a rubber roller, a first gear, and a first toothed plate. By inserting the workpiece into each clamping hole and then moving the lifting frame down into the electroplating tank, the first gear is driven to move down during the downward movement of the lifting frame. As the first gear continues to move down, it meshes with the first toothed plate. At this time, the downward-moving first gear rotates on the first toothed plate. The rotating first gear drives the rubber roller to rotate, and the rotating rubber roller drives the workpiece to move up, thereby exposing the clamping part of the workpiece for electroplating. This prevents the clamping part of the workpiece from being unable to be effectively electroplated and improves the uniformity of electroplating of the workpiece.

[0028] The electroplating device for elevator guide rail production is also equipped with springs, clamping plates, and guide rollers. After the workpiece is inserted into the clamping hole, the spring pushes the clamping plate to drive the guide roller to contact the outer wall of the workpiece, which can assist in clamping the workpiece and ensure that the workpiece inserted into the clamping hole will not fall out. At the same time, as the rubber roller moves the workpiece upward, the rotation of the guide roller facilitates the up and down movement of the workpiece.

[0029] The electroplating device for elevator guide rail production is also equipped with a moving plate, a scraper hole, and a second electric push rod. When it is necessary to clean the liquid flowing on the electroplated workpiece, the second electric push rod is activated to move the moving plate directly above the electroplating tank. Then, the lifting frame continues to move upward, driving the first gear to move upward synchronously. When the first gear and the third gear plate mesh, the first gear rotates and moves upward on the outside of the third gear plate, thereby driving the rubber roller to rotate. The rotating rubber roller can drive the workpiece to move upward. The top of the moved workpiece is inserted into the scraper hole, and the electroplating liquid flowing on the workpiece can be scraped off through the scraper hole to prevent excessive electroplating liquid residue on the workpiece.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Please see Figures 1-10 The present invention provides a technical solution: an electroplating device for elevator guide rail production, including a platform 1, an electroplating tank 5 and a liquid collection tank 36 installed on the top of the platform 1, a lifting frame 3 provided above the platform 1, and a plurality of clamping holes 37 through the lifting frame 3, a stirring component provided inside the lifting frame 3, a frame 2 vertically installed on the top of the platform 1, and a work position adjustment component provided at the top of the frame 2, and a U-shaped frame 4 installed on the top of the platform 1, and a cleaning component provided on the U-shaped frame 4;

[0043] The lifting frame 3 is equipped with an adjustment component for adjusting the position of the workpiece and an auxiliary clamping component for fixing the workpiece.

[0044] The adjustment assembly includes a drive rod 6. The drive rod 6 is installed laterally on both sides of the inner side of the lifting frame 3. A rubber roller 7 is installed on the outer side of the drive rod 6 at each clamping hole 37. A first gear 8 is installed at the end of the drive rod 6 on the outer side of the lifting frame 3. A first toothed plate 23 is symmetrically and vertically installed on the inner wall of the electroplating tank 5. The first toothed plate 23 is used to drive the first gear 8.

[0045] The auxiliary clamping assembly includes mounting slots 14. Multiple mounting slots 14 are provided on both sides of the inner side wall of the lifting frame 3, and springs 11 are installed in each mounting slot 14. Clamping plates 10 are installed at the ends of the springs 11, and the clamping plates 10 are located in the clamping holes 37.

[0046] Specifically, by inserting the workpiece into each clamping hole 37, and then lowering the lifting frame 3 into the electroplating tank 5, the lifting frame 3 drives the first gear 8 to move downward during the downward movement. As the first gear 8 continues to move downward, it meshes with the first toothed plate 23. At this time, the downward-moving first gear 8 rotates on the first toothed plate 23. The rotating first gear 8 drives the rubber roller 7 to rotate, and the rotating rubber roller 7 drives the workpiece to move upward, thereby exposing the clamping part of the workpiece for electroplating. This prevents the clamping part of the workpiece from being unable to be effectively electroplated and improves the uniformity of electroplating of the workpiece.

[0047] After the workpiece is inserted into the clamping hole 37, the spring 11 pushes the clamping plate 10 to drive the guide roller 13 to contact the outer wall of the workpiece, which can assist in clamping the workpiece and ensure that the workpiece inserted into the clamping hole 37 will not fall off. At the same time, as the rubber roller 7 moves the workpiece upward, the rotation of the guide roller 13 facilitates the up and down movement of the workpiece. The first gear 8, the first bevel gear 18, the second bevel gear 19, and the second gear 20 are all made of high-strength plastic.

[0048] Furthermore, multiple guide grooves 15 are provided on both inner side walls of the lifting frame 3, and guide rods 12 are slidably inserted into each guide groove 15, with the ends of the guide rods 12 being installed on the outer wall of the clamping plate 10.

[0049] Specifically, during the clamping process of the clamping plate 10 clamping the workpiece, the guide rod 12 installed on the clamping plate 10 is slidably inserted into the guide groove 15, which can improve the stability of the clamping plate 10 in assisting the clamping of the workpiece and ensure the stability of the workpiece moving up and down.

[0050] Furthermore, damping plates 16 are installed on both inner side walls of the clamping hole 37, and the damping plates 16 are used to increase the resistance to the workpiece.

[0051] Specifically, by having two damping plates 16 in contact with the outer wall of the workpiece, a certain damping effect can be added to the workpiece to prevent it from falling out of the clamping hole 37 under the action of gravity.

[0052] Furthermore, the stirring assembly includes a mounting plate 22, a drive shaft 17 is rotatably mounted laterally inside the lifting frame 3, and a second gear 20 is mounted at the end of the drive shaft 17 outside the lifting frame 3. The mounting plate 22 is rotatably mounted in the middle of the lifting frame 3, and multiple stirring bodies 21 are rotatably mounted on the mounting plate 22. A first bevel gear 18 is mounted on the top of each stirring body 21, and a second bevel gear 19 meshes with each of the first bevel gears 18. The second bevel gears 19 are all mounted on the drive shaft 17. A second toothed plate 24 is vertically mounted inside the electroplating tank 5, and the second toothed plate 24 is used to drive the second gear 20.

[0053] Specifically, during the process of the lifting frame 3 driving the second gear 20 to move downward into the electroplating tank 5, after the second gear 20 moves down and meshes with the second toothed plate 24, the second gear 20 rotates on the second toothed plate 24. The rotating second gear 20 drives the drive shaft 17 to rotate, which in turn drives the second bevel gear 19 to rotate. The second bevel gear 19 then drives the first bevel gear 18 to rotate, which in turn drives the stirring body 21 to rotate. The rotating stirring body 21 can stir the electroplating solution in the electroplating tank 5, ensuring that the metal ions in the electroplating solution are evenly distributed. It can also quickly transport fresh, high-concentration plating solution to the vicinity of the cathode surface, while carrying away the low-concentration solution with consumed ions, thereby improving the uniformity of electroplating.

[0054] Furthermore, the workstation adjustment component includes a rectangular hole 25, which is opened through the top of the frame 2. A lead screw 27 is installed laterally inside the rectangular hole 25. A threaded block 26 is threaded on the outside of the lead screw 27. A motor 29 is installed on the outer wall of the frame 2, and the motor 29 is used to drive the lead screw 27 to rotate.

[0055] Specifically, when it is necessary to move workpieces up and down in the clamping hole 37, the motor 29 is started to drive the lead screw 27 to rotate. The rotating lead screw 27 can drive the threaded block 26 to move laterally in the rectangular hole 25, thereby realizing the transportation of the lifting frame 3 below the threaded block 26. This facilitates the movement of workpieces up and down in the clamping hole 37 on the lifting frame 3. The residual electroplating liquid at the bottom of the workpiece and the bottom of the lifting frame 3 can be collected through the liquid collection tank 36.

[0056] Furthermore, a first electric push rod 30 is vertically installed through the top of the threaded block 26, and a connecting body 38 is installed at the output end of the first electric push rod 30. The bottom of the connecting body 38 is installed on the top of the lifting frame 3, and guide posts 28 are vertically symmetrically installed on the top of the connecting body 38. The top of the guide posts 28 slides through the threaded block 26.

[0057] Specifically, when it is necessary to drive the lifting frame 3 up and down, the first electric push rod 30 is activated to drive the connecting body 38 to move up and down, which in turn drives the lifting frame 3 to move up and down. The guide column 28 installed vertically on the top of the connecting body 38 can improve the stability of the connecting body 38 moving up and down.

[0058] Furthermore, the cleaning assembly includes a moving plate 32, a second electric push rod 34 is installed through the U-shaped frame 4, the output end of the second electric push rod 34 is installed with the moving plate 32, and multiple scraping holes 33 are opened through the moving plate 32. A third toothed plate 31 is vertically and symmetrically installed on the inner wall of the frame 2 above the electroplating tank 5, and the third toothed plate 31 is used to drive the first gear 8.

[0059] Specifically, when it is necessary to clean the liquid flowing on the electroplated workpiece, the second electric push rod 34 is activated to move the transfer plate 32 to directly above the electroplating tank 5. Then, the lifting frame 3 moves upward synchronously, driving the first gear 8 to move upward. When the first gear 8 and the third toothed plate 31 mesh, the first gear 8 rotates and moves upward on the outside of the third toothed plate 31, thereby driving the rubber roller 7 to rotate. The rotating rubber roller 7 can drive the workpiece to move upward. The top of the moved workpiece is inserted into the scraper hole 33. The scraper hole 33 can scrape away the electroplating liquid flowing on the workpiece to prevent excessive electroplating liquid residue on the workpiece.

[0060] Furthermore, guide plates 35 are installed on both sides of the scraper hole 33 at the bottom of the sliding plate 32, and the guide plates 35 are installed at an angle.

[0061] Specifically, a guide plate 35 is installed at the bottom of each scraper hole 33 via the bottom of the moving plate 32. When the workpiece is moved upward and needs to be inserted into the scraper hole 33, the guide plate 35 guides the workpiece to ensure that the workpiece can be smoothly inserted into the scraper hole 33. Since the inner wall of the scraper hole 33 and the outer wall of the workpiece are in close contact, the electroplating liquid flowing on the workpiece can be scraped off.

[0062] This device cannot completely clean the electroplating solution from the workpiece, so the workpiece needs to be transported to the drying area for drying. The purpose of this device is to solve the problem of electroplating solution dripping from the workpiece.

[0063] Furthermore, anti-tilting rollers 9 are symmetrically and rotatably installed on the inner wall of the clamping hole 37, and the anti-tilting rollers 9 are distributed at the upper and lower positions of the rubber roller 7.

[0064] Specifically, when the rubber roller 7 rotates and drives the workpiece to move up and down, two anti-tilting rollers 9 are distributed at the upper and lower positions of the rubber roller 7 to guide the workpiece moving up and down and prevent the workpiece from deviating.

[0065] Working principle: When using the electroplating device for elevator guide rail production, before inserting the workpiece into the clamping hole 37, the lifting frame 3 needs to be moved to the top position of the liquid collection tank 36. Then, the workpiece is inserted into the clamping hole 37 in sequence, with the clamping part of the workpiece located in the middle position. Then, the motor 29 is started to drive the lead screw 27 to rotate. The rotating lead screw 27 can drive the threaded block 26 to move laterally within the rectangular hole 25, transporting the lifting frame 3 below the threaded block 26 to directly above the electroplating tank 5. Subsequently, the first electric push rod 30 is started to drive the connecting body 38 to move up and down, thereby driving the lifting frame 3 to move up and down. The lowering frame 3 moves up and down, simultaneously activating the electroplating equipment in the electroplating tank 5 to electroplat the bottom of the workpiece. As the first gear 8 continues to move down and meshes with the first toothed plate 23, the descending first gear 8 rotates on the first toothed plate 23. The rotating first gear 8 drives the rubber roller 7 to rotate, which in turn moves the workpiece upward. Before this, the electroplating solution has completely immersed the workpiece, and most of the workpiece has been electroplated, exposing the clamping part of the workpiece for electroplating. At the same time, when the second gear 20 moves down and meshes with the second toothed plate 24, the second gear 20... The second gear 20 rotates on the second gear plate 24, which in turn drives the drive shaft 17 to rotate. The drive shaft 17 then drives the second bevel gear 19 to rotate, which in turn drives the first bevel gear 18 to rotate. The first bevel gear 18 then drives the stirring body 21 to rotate, thus stirring the electroplating solution in the electroplating tank 5. After electroplating is complete, the lifting frame 3 needs to be moved upwards to remove the workpiece from the electroplating tank 5. Then, the second electric push rod 34 is activated to move the moving plate 32 to directly above the electroplating tank 5, and then the lifting frame 3 is moved upwards. The lifting frame 3 drives the first gear 8 to move upward synchronously. When the first gear 8 and the third toothed plate 31 mesh, the first gear 8 rotates and moves upward on the outside of the third toothed plate 31, thereby driving the rubber roller 7 to rotate. The rotating rubber roller 7 can drive the workpiece to move upward. The top of the workpiece is inserted into the scraper hole 33. The scraper hole 33 can scrape away the electroplating liquid flowing on the workpiece to prevent excessive electroplating liquid residue on the workpiece. Finally, the lifting frame 3 is moved above the liquid collection tank 36 to remove the workpiece.
