Description

Technical Field

[0001] This utility model relates to the field of electroplating tooling technology for automotive decorative parts, and more specifically, it relates to a tooling for electroplating automotive decorative parts. Background Technology

[0002] In the automotive manufacturing industry, electroplating fixtures for decorative parts are key equipment for surface treatment. Their operating efficiency, clamping adaptability, and fixing stability directly affect the electroplating quality and production efficiency. However, the electroplating fixtures currently on the market still have many technical defects in practical applications. These problems not only affect the processing effect but may also lead to product quality defects.

[0003] The primary problem is low operational efficiency. Existing electroplating fixtures have significant defects: First, manual clamping operations consume a lot of manpower, and manual operation is prone to fatigue errors. Traditional manual processes not only reduce production efficiency, but may also damage decorative parts due to improper operation. This design deficiency not only affects the production cycle, but may also lead to product scrap due to human error, increasing production costs and personnel burden.

[0004] More notably, the clamping adaptability is poor. Although some electroplating fixtures use mechanized equipment, there are obvious problems. The simple clamping plate structure cannot adapt to complex shapes. Secondly, large-area contact affects the uniformity of electroplating. Furthermore, the single fixing method makes it difficult to match different workpieces. In addition, unreasonable clamping methods not only affect the electroplating coverage area, but may also cause scratches on the workpiece surface due to improper contact. This design deficiency not only reduces the product qualification rate, but may also affect the electroplating effect due to improper clamping, increasing rework and quality costs.

[0005] Most critically, the stability of the fixture is insufficient. Although some equipment has achieved multi-point clamping function, there are serious problems: First, the connection structure is simple in design, and the inertia of the equipment during movement can easily cause the fixture to loosen; second, the vibration during the electroplating process affects the clamping stability. The loose structure not only affects the electroplating quality, but may also cause the workpiece to fall off, resulting in processing accidents. This design deficiency not only affects the stability of product quality, but may also cause workpiece damage due to fixation failure, increasing the quality risk in the production process.

[0031] Please see Figures 1-5A tooling for electroplating automotive trim parts includes a mounting frame 1. A clamping device is located below the mounting frame 1. The clamping device includes a lifting block 2, a first lead screw 3, and a sliding frame 4. The first lead screw 3 is rotatably mounted inside the sliding frame 4. The lifting block 2 is movably connected to the first lead screw 3 via threads. An adapter device is mounted on one side of the lifting block 2. The adapter device includes contact rods 5, a control sleeve 6, a connecting sleeve 7, a slanted groove 8, an adapter groove 9, an adapter sleeve 10, a fixing block 11, a slanted plate 12, and an adapter plate 13. Multiple contact rods 5 slide through the adapter sleeve 10. The control sleeve 6 is rotatably mounted on the outside of the connecting sleeve 7. The inner wall of the control sleeve 6 is movably connected to the outer wall of the adapter sleeve 10 via threads. The connecting sleeve 7 is fixedly mounted on one side of the lifting block 2. The slanted groove 8 is formed... Inside the connecting sleeve 7, an adapter groove 9 is formed at one end of the adapter sleeve 10. A fixing block 11 is fixedly connected to one side of the inclined plate 12. The inclined plate 12 is slidably installed inside the inclined groove 8. An adapter plate 13 is fixedly connected to one side of the fixing block 11 and is slidably installed in the adapter groove 9. A locking mechanism is provided on the outside of the connecting sleeve 7. The locking mechanism includes a limiting sleeve 14, a locking rod 15, a push spring 16, a locking block 17, a rotating groove 18, and a locking slot 19. The limiting sleeve 14 is movably installed on the outside of the connecting sleeve 7 by a thread. The locking rod 15 is fixedly connected to one side of the locking block 17. The push spring 16 is movably sleeved on the outside of the locking rod 15. The rotating groove 18 is formed on one side of the control sleeve 6. Multiple locking slots 19 are formed in the rotating groove 18. The end of the locking block 17 is inserted into the locking slot 19.

[0032] The mounting bracket 1 is rotatably provided with a second lead screw 20. The two ends of the second lead screw 20 are symmetrically provided with opposite threads, and the two sliding brackets 4 are respectively movably connected to the second lead screw 20 through threads. The sliding brackets 4 and the mounting bracket 1 are both fixedly provided with sliding rods 21. The sliding brackets 4 and the lifting block 2 are respectively slidably connected to the corresponding sliding rods 21.

[0033] A second motor 22 is detachably mounted on one side of the mounting bracket 1, and a first motor 23 is mounted above one of the sliding brackets 4.

[0034] Both the output end of the first motor 23 and the output end of the second motor 22 are connected to a reducer 24, and the two reducers 24 are respectively connected to one end of the first lead screw 3 and the second lead screw 20.

[0035] In this embodiment, when the device is needed, the adapter is first locked, then the lifting block 2 is at its highest point. The decorative part to be electroplated is then positioned between the two clamping blocks. The second motor 22 is then activated. After being decelerated by the reducer 24, the output of the second motor 22 drives the second lead screw 20 connected to the reducer 24 to rotate in the forward direction. The two sliding frames 4 then move synchronously inward along the sliding rod 21, thereby causing the two lifting blocks 2 and the connecting sleeve 7 to move inward in opposite directions. When the spherical ends of the contact rod 5 are both in contact with the device... When the outer surface of the decorative piece comes into contact, the second motor 22 is turned off, and then the adapter is readjusted to the locked state to ensure stable clamping. Then, the two first motors 23 are turned on simultaneously. After the output end of the first motor 23 is decelerated by the reducer 24 connected to the output end, it drives the first lead screw 3 connected to the output end of the reducer 24 to rotate, so that the two first lead screws 3 rotate synchronously in the forward direction. Then, the two lifting blocks 2 will drive the connecting block and contact rod 5 and other components to descend synchronously along the slide bar 21, thereby driving the clamped decorative piece to descend and immerse it in the electroplating solution for electroplating processing.

[0036] Please see Figures 3-5 As a further implementation of the overall equipment: a fixing sleeve 25 is fixedly provided on the inner side of the connecting sleeve 7, an end plate 26 is connected to one end of the contact rod 5, and a return spring 27 is movably sleeved on the outer side of the contact rod 5. The two ends of the return spring 27 are respectively connected to an end plate 26 and a fixing sleeve 25.

[0037] A limiting plate 28 is fixedly provided on the outside of the connecting sleeve 7, and multiple locking rods 15 slide through the limiting plate 28.

[0038] Both the end of the card block 17 and the edge of the card slot 19 are designed with rounded corners.

[0039] The end of contact rod 5 has a spherical structure design.

[0040] More specifically, when it is necessary to contact the locked state of the adapter, firstly, the limiting sleeve 14 is rotated forward, causing it to move along the threads on the outer wall of the connecting sleeve 7, so that the limiting sleeve 14 no longer limits one end of the locking rod 15. Then, the control sleeve 6 is rotated forward, causing the rotating groove 18 and the locking groove 19 on one side to rotate. Then, the inner wall of the locking groove 19 presses against the end of the locking block 17, causing the locking block 17 to slide out of the locking groove 19 and into the rotating groove 18. Then, the locking block 17 drives the locking rod 15 to slide along the limiting plate 28, and the locking block 17 and the limiting plate 28 cooperate to press against the push spring 16. At the same time, due to the threaded connection between the outer wall of the adapter 10 and the inner wall of the control sleeve 6... Then, the adapter 10, through the cooperation of the adapter groove 9 and the adapter block, drives the fixing block 11 to move to one side. Then, the fixing block 11 drives the inclined plate 12 on one side to slide along the inclined groove 8. At the same time, the inclined plate 12 drives the fixing block 11 to move outward, so that the inner wall of the fixing block 11 no longer abuts against the outer wall of the contact rod 5. The fixing block 11 also drives the adapter plate 13 on one side to slide along the adapter groove 9. Then, the sliding frame 4, through the lifting block 2, drives the connecting sleeve 7 and the contact rod 5 to move inward, so that the spherical end of the contact rod 5 contacts the outer surface of the decorative part. The contact rod 5 that first contacts the outer surface of the decorative part no longer moves. Then, the fixing sleeve 25 slides along the contact rod 5 at this point, and drives its... As the contact rod 5 continues to move, the end plate 26 and the fixing sleeve 25 at the end of the contact rod 5 cooperate to stretch the return spring 27 sleeved on the outside. When all the contact rods 5 are in contact with the outer surface of the decorative part, most of the tension springs sleeved on the outside of the contact rods 5 will be stretched to varying degrees. Then, the adapter needs to be switched to the locked state. First, the control sleeve 6 is rotated in the opposite direction, so that the control sleeve 6 drives the rotating groove 18 and the slot 19 opened on one side to rotate and reset. The adapter 10 will push the fixing block 11 to slide and reset in the opposite direction. Then, the fixing block 11 drives the inclined plate 12 to slide and reset in the opposite direction along the inclined groove 8. Then, the inclined plate 12 drives the fixing block 11 to gradually gather inward, so that the fixing... The inner wall of block 11 presses against the outer wall of contact rod 5 again, preventing contact rod 5 from sliding. At the same time, the fixing block 11 drives the adapter plate 13 on one side to slide back along the adapter groove 9. When the fixing block 11 presses against the outer wall of contact rod 5 again, the push spring 16 pushes the locking block to slide back, so that the end of the locking block is re-inserted into the original locking groove. At the same time, the locking block will drive the locking rod to slide back along the limiting plate 28. Then, the limiting sleeve 14 rotates in the opposite direction, so that the limiting sleeve 14 limits one end of the locking rod 15 again, so that the locking rod 15 and the locking block 17 cannot move. Then, the locking block 17 and the locking groove 19 cooperate to lock the control sleeve 6, preventing the control sleeve 6 from moving, thereby ensuring stable clamping.

[0041] In summary, when using or operating the entire equipment: First, engage the locking state of the adapter, then position the lifting block 2 at its highest point. Next, position the decorative part to be electroplated between the two clamping blocks. Then, activate the second motor 22. After being decelerated by the reducer 24, the output of the second motor 22 drives the second lead screw 20 connected to the reducer 24 to rotate forward. Then, the two sliding frames 4 move synchronously inward along the sliding rod 21, thereby causing the two lifting blocks 2 and the connecting sleeve 7 to move inward in opposite directions. When the ball of the contact rod 5... When both ends are in contact with the outer surface of the decorative part, the second motor 22 is turned off, and then the adapter is readjusted to the locked state to ensure stable clamping. Then, the two first motors 23 are turned on simultaneously. After the output end of the first motor 23 is decelerated by the reducer 24 connected to the output end, it drives the first lead screw 3 connected to the output end of the reducer 24 to rotate, so that the two first lead screws 3 rotate synchronously in the forward direction. Then, the two lifting blocks 2 will drive the connecting block and contact rod 5 and other components to descend synchronously along the slide bar 21, thereby driving the clamped decorative part to descend and immerse it in the electroplating solution for electroplating processing.

[0042] When it is necessary to release the locked state of the adapter, first rotate the limiting sleeve 14 forward, causing it to move along the threads on the outer wall of the connecting sleeve 7, so that the limiting sleeve 14 no longer limits one end of the locking rod 15. Then rotate the control sleeve 6 forward, causing the rotating groove 18 and the locking groove 19 on one side to rotate. Then, the inner wall of the locking groove 19 presses against the end of the locking block 17, causing the locking block 17 to slide out of the locking groove 19 and slide into the rotating groove 18. Then, the locking block 17 drives the locking rod 15 to slide along the limiting plate 28, and the locking block 17 and the limiting plate 28 cooperate to press against the push spring 16. At the same time, due to the threaded connection between the outer wall of the adapter 10 and the inner wall of the control sleeve 6, the adapter... The matching 10, through the cooperation of the adapter groove 9 and the adapter block, drives the fixing block 11 to move to one side. Then, the fixing block 11 drives the inclined plate 12 on one side to slide along the inclined groove 8. At the same time, the inclined plate 12 drives the fixing block 11 to move outward, so that the inner wall of the fixing block 11 no longer abuts against the outer wall of the contact rod 5. The fixing block 11 also drives the adapter plate 13 on one side to slide along the adapter groove 9. Then, the sliding frame 4, through the lifting block 2, drives the connecting sleeve 7 and the contact rod 5 and other components to move inward, so that the spherical end of the contact rod 5 contacts the outer surface of the decorative part. The contact rod 5 that first contacts the outer surface of the decorative part no longer moves. Then, the fixing sleeve 25 slides along the contact rod 5 at this point, and drives the other components to move inward. The contact rod 5 continues to move, and then the end plate 26 and the fixing sleeve 25 at the end of the contact rod 5 cooperate to stretch the return spring 27 sleeved on the outside. When all the contact rods 5 are in contact with the outer surface of the decorative part, most of the tension springs sleeved on the outside of the contact rods 5 will be stretched to varying degrees. Then, the adapter needs to be switched to the locked state. First, the control sleeve 6 is rotated in the opposite direction, so that the control sleeve 6 drives the rotating groove 18 and the slot 19 opened on one side to rotate and reset. The adapter 10 will push the fixing block 11 to slide and reset in the opposite direction. Then, the fixing block 11 drives the inclined plate 12 to slide and reset in the opposite direction along the inclined groove 8. Then, the inclined plate 12 drives the fixing block 11 to gradually gather inward, so that the fixing block The inner wall of the 11 block presses against the outer wall of the contact rod 5 again, preventing the contact rod 5 from sliding. At the same time, the fixing block 11 drives the adapter plate 13 on one side to slide back along the adapter groove 9. When the fixing block 11 presses against the outer wall of the contact rod 5 again, the push spring 16 pushes the locking block to slide back, so that the end of the locking block is re-inserted into the original locking groove. At the same time, the locking block will drive the locking rod to slide back along the limiting plate 28. Then, the limiting sleeve 14 rotates in the opposite direction, so that the limiting sleeve 14 limits one end of the locking rod 15 again, so that the locking rod 15 and the locking block 17 cannot move. Then, the locking block 17 and the locking groove 19 cooperate to lock the control sleeve 6, preventing the control sleeve 6 from moving, thereby ensuring stable clamping.
