[0002] Electrophoretic coating is often used in the production and processing of automobile parts. Electrophoretic coating is a coating method that uses an external electric field to make particles such as pigments and resins suspended in the electrophoretic liquid migrate in a directional manner and deposit on the surface of a substrate of one of the electrodes. Currently, when electrophoretic coating is performed on automobile parts, the automobile parts clamped on the fixture are moved and flipped inside the coating electrophoretic tank by a robotic arm, thereby realizing the electrophoretic coating of the automobile parts.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of specific embodiments of the present invention.

[0035] Please refer to Figures 1 to 11 As shown:

[0037] A return spring 3022 is disposed outside the control tube 302 , and two ends of the return spring 3022 abut against the side surface of the control tube 302 and the side surface of the accessory clamp 303 , respectively.

[0038] Among them, a synchronization rod 2031 with a regular polygonal cross-section is provided on the side of the operating rod 203, and a synchronization groove 2041 is provided inside the limiting plate 204, and the synchronization rod 2031 is inserted into the synchronization groove 2041. In use, the two sets of loose clamping mechanisms 2 can clamp and fix different parts of the automotive accessories respectively, so that the clamp assembly can adapt to the clamping and positioning operations of different types of automotive accessories, ensuring the stability and efficiency of its electrophoretic coating processing. When the operating rod 203 is rotated in the positive direction (here, when the positioning screw 202 rotates, the two sets of clamping block mechanisms 3 are driven to move synchronously toward each other through the rod body thread, and the rotation direction of the positioning screw 202 is the positive direction), the synchronization rod 2031 of the operating rod 203 can drive the limiting plate 204 to rotate synchronously through the synchronization groove 2041, and the outer side of the synchronization rod 2031 A limit top spring 2032 is sleeved, and the two ends of the limit top spring 2032 are respectively against the side of the operating rod 203 and the side of the limit plate 204. Under the action of the limit top spring 2032, the limit plate 204 drives the positioning screw 202 to rotate synchronously under the mutual friction and extrusion of the beveled edges of the teeth of the limit tooth ring 2021 of the positioning screw 202 when rotating. When the positioning screw 202 rotates, it can drive the two groups of clamping block mechanisms 3 to approach each other through the rod body thread to achieve clamping and use of automotive accessories. Under the action of the reset top spring 3022, the relative positions of the positioning block 301, the control cylinder 302 and the accessory clamping block 303 will not change. Therefore, the two groups of clamping block mechanisms 3 are close to each other and can achieve the clamping and positioning operation of the automotive accessories through the accessory clamping block 303. The operation is convenient and flexible.

[0039] Among them, the opposite sides of the limit plate 204 and the positioning screw 202 are provided with a limit tooth ring 2021, and the cross-sectional shape of a single tooth of the limit tooth ring 2021 is a right triangle, the teeth of the limit plate 204 and the limit tooth ring 2021 of the positioning screw 202 are engaged with each other, and when the positioning screw 202 rotates in the opposite direction, the straight edges of the teeth of the limit plate 204 and the limit tooth ring 2021 of the positioning screw 202 are engaged with each other. In use, when it is necessary to remove the automotive accessories from the clamp assembly, it is only necessary to rotate the operating rod 203 in the opposite direction. When the operating rod 203 rotates in the opposite direction, it can drive the limit plate 204 to reverse synchronously. When the limit plate 204 reverses, the straight edges of the teeth of the limit tooth ring 2021 on the side of the positioning screw 202 can be engaged with each other, thereby driving the positioning screw 202 to reverse stably to realize the operation of moving the two clamping block mechanisms 3 away from each other, and then the automotive accessories can be removed, and the operation is convenient and flexible.

[0040] Specific usage and function of this embodiment: In the present invention, after the automobile parts are fixed on the clamp assembly, the mobile mechanical arm can drive the clamp assembly to move three-dimensionally through the connecting piece 5, so that the automobile parts are placed inside the coating electrophoretic tank 101 for moving, flipping and other actions to realize the electrophoretic coating processing operation. The two sets of loose clamping mechanisms 2 can clamp and fix different parts of the automobile parts respectively, so that the clamp assembly can adapt to the clamping and positioning operations of different types of automobile parts, ensuring the stability and efficiency of its electrophoretic coating processing. When the operating rod 203 is rotated in the positive direction (here, when the positioning screw 202 rotates, the two sets of clamping block mechanisms 3 are driven to move synchronously towards each other through the rod body thread, and the rotation direction of the positioning screw 202 is the positive direction), the synchronization rod 2031 of the operating rod 203 can drive the limit plate 204 to rotate synchronously through the synchronization groove 2041. Under the action of the limit top spring 2032, the limit plate 204 rotates in the limit tooth ring 221 of the positioning screw 202. The mutual friction and extrusion of the beveled edges of the gear teeth drive the positioning screw 202 to rotate synchronously in the forward direction. When the positioning screw 202 rotates, it can drive the two groups of clamping block mechanisms 3 to approach each other through the rod body thread to achieve the clamping and use of the automobile accessories. Under the action of the reset top spring 3022, the relative positions of the positioning block 301, the control cylinder 302 and the accessory clamping block 303 will not change. Therefore, the two groups of clamping block mechanisms 3 approach each other and can achieve the clamping and positioning operation of the automobile accessories through the accessory clamping block 303. After the processing is completed, the automobile accessories can be removed. When the automobile accessories need to be removed from the clamp assembly, it is only necessary to rotate the operating rod 203 in the opposite direction. When the operating rod 203 rotates in the opposite direction, it can drive the limit plate 204 to reverse synchronously. When the limit plate 204 reverses, the straight edges of the gear teeth of the limit tooth ring 2021 on the side of the positioning screw 202 can be engaged with each other, thereby driving the positioning screw 202 to stably reverse to achieve the operation of the two clamping block mechanisms 3 moving away from each other, and then the automobile accessories can be removed.

[0041] Embodiment 2: On the basis of Embodiment 1, a "V"-shaped, spiral release groove 3021 is provided on the outside of the control cylinder 302, and a release protrusion 3031 is provided on the inside of the accessory clamp 303. The release protrusion 3031 is inserted into the inside of the release groove 3021. The release groove 3021 is "V"-shaped and spirally designed so that no matter how the incomplete gear 4011 rotates, the control cylinder 302 can always drive the accessory clamp 303 to move in a direction away from the automotive accessories through the cooperation of the release groove 3021 and the release protrusion 3031 during rotation, and is stable to use.

[0042] Among them, an incomplete gear 4011 is provided on the top of the driving gear 401, and the incomplete gears 4011 of the two sets of clamp assemblies are set at different heights, and two sets of intermittent racks 1021 with different heights and positions are provided on the side of the reference block 102, and the two sets of intermittent racks 1021 are respectively located on the moving paths of the incomplete gears 4011 of the two sets of clamp assemblies. In use, when any loosening mechanism 2 moves to the position of the intermittent rack 1021 corresponding to its position, the clamping block mechanism 3 of this set of loosening mechanism 2 can be automatically released at this time, releasing the contact and clamping fixing relationship between the accessory clamping block 303 and the automobile accessory, so that this part of the automobile accessory can be fully aligned with the coating electrostatic tank 10 1, the solution inside the control cylinder 302 is contacted and reacted to realize the processing operation, which is stable in use and greatly improves the electrophoresis processing efficiency of automobile parts. When the clamp release mechanism 2 moves to the intermittent rack 1021 corresponding to its position, the intermittent rack 1021 can drive the driving gear 401 to rotate through the incomplete gear 4011. The control cylinder 302 is provided with a transmission groove 3023 inside, and the side of the control gear 402 is provided with a transmission rod 4021 with a regular polygonal cross section. The transmission rod 4021 is inserted into the transmission groove 3023. When the driving gear 401 rotates, it can drive the transmission rod 4021 to rotate synchronously through the control gear 402. When the transmission rod 4021 rotates, it can drive the transmission rod 4021 to rotate synchronously through the transmission groove 3023. The groove 3023 drives the control cylinder 302 to rotate. When the control cylinder 302 rotates, the groove 3021 is released, which can drive the accessory clamping block 303 to move outward and compress the reset top spring 3022 by releasing the protrusion 3031, thereby realizing the function of releasing the contact between the accessory clamping block 303 and the automobile accessory and the clamping and fixing relationship. It is stable and convenient to use. Since the setting positions and heights of the two sets of intermittent racks 1021 are mutually offset, and the setting heights of the two incomplete gears 4011 are also different, there will be at least one set of loosening mechanisms 2 to clamp and fix the automobile accessories during the electrophoretic coating processing operation, so that the automobile accessories will not fall off during the processing, the processing is stable, and the two sets of loosening mechanisms 2 can alternately release the automobile accessories and can completely perform electrophoretic coating on the automobile accessories. When the incomplete gear 4011 has not left the position of the intermittent rack 1021, the gear teeth of the incomplete gear 4011 can be clamped by the intermittent rack 1021 after rotating to the maximum angle, so that the incomplete gear 4011 will not automatically reset as long as it is on the bar body of the intermittent rack 1021. When the incomplete gear 4011 leaves the intermittent rack 1021, the reset top spring 3022 can drive the accessory clamp 303 to move toward the direction of the automobile accessories, thereby restoring the clamping and fixing effect on the automobile accessories, and the intermittent mechanism 4 can also automatically reset during this process, which is flexible and convenient to use.

[0043] Among them, the elasticity specification of the reset top spring 3022 is much greater than the elasticity specification of the limit top spring 2032. In use, when the automobile accessory is clamped and fixed by rotating the operating rod 203 in the forward direction, when the clamping force (i.e., the rotational resistance of the positioning screw 202 when clamping the automobile accessory) is greater than the positioning force of the limit top spring 2032 on the limit plate 204, the limit plate 204 and the beveled edges of the limit tooth ring 2021 on the side of the positioning screw 202 will squeeze each other to avoid continuing to transmit the positioning screw 202, and since the elasticity specification of the limit top spring 2032 is less than the elasticity specification of the reset top spring 3022, when the clamp assembly reaches the maximum clamping force, the relative position between the accessory clamp block 303 and the control cylinder 302 will not be changed, that is, the release protrusion 3031 is always in the middle position of the "V"-shaped groove body of the release groove 3021, which facilitates the subsequent electrophoretic coating processing operation. The clamp block mechanism 3 of the two sets of loosening mechanisms 2 can alternately release the function of the automobile accessories.

[0044] Specific usage and function of this embodiment: In the present invention, when the clamp assembly moves inside the coating electrophoretic tank 101, when any clamping release mechanism 2 moves to the intermittent rack 1021 corresponding to its position, the clamping block mechanism 3 of the clamping release mechanism 2 can be automatically released, and the contact and clamping relationship between the accessory clamping block 303 and the automobile accessory are released, so that the part of the automobile accessory can fully contact and react with the solution inside the coating electrophoretic tank 101 to realize the processing operation, which is stable to use and greatly improves the electrophoresis processing efficiency of the automobile accessories. When the clamping release mechanism 2 moves to the intermittent rack 1021 corresponding to its position, the intermittent rack 1021 can drive the driving gear 401 through the incomplete gear 4011. When the driving gear 401 rotates, it can drive the transmission rod 4021 to rotate synchronously through the control gear 402. When the transmission rod 4021 rotates, it can drive the control cylinder 302 to rotate through the transmission groove 3023. When the control cylinder 302 rotates, the release groove 3021 can drive the accessory clamping block 303 to move outward through the release protrusion 3031 and compress the reset top spring 3022, thereby realizing the function of releasing the contact between the accessory clamping block 303 and the automobile accessory and the clamping and fixing relationship. It is stable and convenient to use. Since the setting positions and heights of the two sets of intermittent racks 1021 are mutually offset, and the setting heights of the two incomplete gears 4011 are also different, there will be at least one set of loosening mechanisms 2 to clamp the automobile accessories during the electrophoretic coating processing operation. The automobile parts are fixed so that the automobile parts will not fall off during the processing, and the processing is stable. The clamping block mechanisms 3 of the two sets of loosening mechanisms 2 can alternately loosen the automobile parts, and the automobile parts can be completely electrophoretically coated. When the incomplete gear 4011 has not left the position of the intermittent rack 1021, the gear teeth of the incomplete gear 4011 can be clamped by the intermittent rack 1021 after the incomplete gear 4011 rotates to the maximum angle, so that the incomplete gear 4011 will not automatically reset as long as it is on the bar body of the intermittent rack 1021. When the incomplete gear 4011 leaves the intermittent rack 1021, the reset top spring 3022 can drive the accessory clamping block 303 to move toward the direction of the automobile parts, thereby restoring the clamping and fixing effect on the automobile parts, and the intermittent machine in the process The structure 4 can also be reset automatically, and when the automobile accessory is clamped and fixed by the positive rotation of the operating rod 203, when the clamping force (i.e., the rotation resistance of the positioning screw 202 when clamping the automobile accessory) is greater than the positioning force of the limiting top spring 2032 on the limiting plate 204, the limiting plate 204 and the beveled edges of the limiting tooth ring 2021 on the side of the positioning screw 202 will squeeze each other to avoid each other and will not continue to transmit the positioning screw 202, and because the elasticity specification of the limiting top spring 2032 is smaller than the elasticity specification of the reset top spring 3022, when the clamp assembly reaches the maximum clamping force, the relative position between the accessory clamp 303 and the control cylinder 302 will not be changed, that is, the release protrusion 3031 is always in the middle position of the "V"-shaped groove body of the release groove 3021.This facilitates the function of the clamping block mechanisms 3 of the two sets of loosening mechanisms 2 to alternately loosen the automobile accessories in the subsequent electrophoretic coating processing operation.
