Description

Technical Field

[0001] This application relates to the field of metal processing technology, and in particular to a clamping structure for surface treatment of metal parts. Background Technology

[0002] Surface treatment of metal parts requires the workpiece to be fixed by a clamping mechanism to ensure precise positioning and stability during the treatment process. The design of the clamping structure directly affects the treatment quality. Conventional clamps (such as mechanical jaws and magnetic clamps) can provide stable clamping, but they can easily obscure local surfaces of the metal parts. The contact area between the clamp and the metal parts cannot be fully covered by the treatment fluid, forming untreated or insufficiently treated shadow areas or dead corners, resulting in incomplete cleaning.

[0003] For example, in CN202421042369.4, a reliable clamping metalworking fixture is disclosed. This device fixes the metal part in the middle only by clamping plates that move in opposite directions on both sides. However, the surface of the metal part is covered and blocked at the same time, resulting in incomplete cleaning. Utility Model Content

[0004] To address the issue that metal part clamping structures can easily cover or obstruct the surface of metal parts, leading to incomplete cleaning, this application provides a metal part surface treatment clamping structure.

[0005] The metal part surface treatment clamping structure provided in this application adopts the following technical solution:

[0006] A metal part surface treatment clamping structure includes a main housing. Clamping mechanisms for clamping metal parts are provided on both sides of the outer surface of the main housing. Alignment rods are provided on both sides of the clamping mechanisms at the top of the main housing. The alignment rods on both sides movably pass through the top of the clamping mechanisms to balance the alignment of the two ends of the clamping mechanisms. A limit baffle is provided protruding from the surface of the main housing. A support plate for supporting the metal parts to extend, descend, and rotate is provided on the upper surface of the limit baffle.

[0007] By adopting the above technical solution, the clamping mechanism clamps the metal parts conveyed into the main housing and drives the metal parts to rotate longitudinally, thereby facilitating the removal of residual liquid and debris from the surface of the metal parts. Then, the tray rises to lift the metal parts that have been unclamped and rotates them laterally, exposing the part of the metal parts that contacted the clamping mechanism to the outside for cleaning, thus avoiding the situation where the surface of the metal parts is covered and cannot be completely cleaned when they are clamped by the clamping mechanism.

[0008] Preferably, the clamping mechanism includes movable plates movably disposed at both ends of the side surface of the main housing, a rotating rod is rotatably disposed on the top of each of the two movable plates on opposite sides, a movable clamp is fixedly disposed on opposite ends of each of the two rotating rods, and a clamping groove is provided on opposite sides of each of the two movable clamps.

[0009] By adopting the above technical solution, when the two moving plates move towards each other, they drive the two moving clamps to move towards each other, thereby clamping the metal parts. At the same time, the two sides of the metal parts abut against the inner wall of the clamping groove to form a snap-fit ​​fixation, preventing loosening during the cleaning of the metal parts.

[0010] Preferably, a moving groove is provided on the lower end face of the main housing, which is aligned with the moving clamp. The middle part of the moving groove passes through the main housing and communicates with the middle part of the limiting baffle. A threaded rod is rotatably provided in the moving groove, and the bottom of both moving plates is threadedly connected to the threaded rod.

[0011] By adopting the above technical solution, the threaded rod is rotatably connected to the moving plates on both sides of the moving groove, so that when the threaded rod rotates, it drives the two moving plates to move in opposite directions along the surface of the threaded rod.

[0012] Preferably, the threaded rod has a connecting smooth surface intermittently arranged in the middle, and an electromagnetic clutch is fixed at the intermittent part of the connecting smooth surface. The stator end of the electromagnetic clutch is fixedly connected to both sides of the intermittent connecting smooth surface. The stator end surface of the electromagnetic clutch is provided with a straight tooth surface, and the rotor end surface of the electromagnetic clutch is fixedly provided with a helical tooth surface. A spur gear that meshes with the straight tooth surface is provided at the bottom of the electromagnetic clutch, and a first motor is fixedly arranged on one side of the middle part of the spur gear.

[0013] By adopting the above technical solution, the first motor drives the spur gear to rotate, causing the spur tooth surface meshing with the spur gear to rotate. The electromagnetic clutch controls the opening and closing of the connection between the spur tooth surface and the helical tooth surface, thereby causing the spur tooth surface to drive the threaded rod to rotate, while controlling the helical tooth surface to drive the helical gear to rotate synchronously and asynchronously.

[0014] Preferably, the main housing is movably provided with an electric push rod fixedly connected to the support plate in the middle of the limiting baffle, and a helical gear fixedly connected to the bottom of the electric push rod is rotatably provided in the through opening of the moving groove, and the bottom of the helical gear meshes with one side surface of the helical tooth surface.

[0015] By adopting the above technical solution, the helical gear is driven to rotate by the helical tooth surface, which in turn drives the support plate at the top of the electric push rod to rotate. The support plate drives the metal part to rotate, thereby turning out the part of the metal part located in the clamping groove for cleaning.

[0016] Preferably, a material plate is clamped in the middle of the two movable clamps, and the alignment rods on both sides move through the two movable clamps in sequence. Brush bristles are fixed on the middle surface of the alignment rods on both sides, and limiting rings are fixed on the two side surfaces of the alignment rods on both sides.

[0017] By adopting the above technical solution, the moving fixture holds the material plate, which facilitates the fixing and rotation of the material plate. At the same time, when the material plate enters the range of the main housing, the alignment rod provides auxiliary support for the material plate. As the material plate moves, the bristles contact the surface of the material plate, forming an auxiliary cleaning process for the first step.

[0018] Preferably, a second motor is fixedly mounted on the surface of one of the two movable plates away from the other movable plate, and the output end of the second motor movably passes through the movable plate and is fixedly connected to the rotating rod.

[0019] By adopting the above technical solution, the second motor drives the rotating rod to rotate, thereby providing power for the rotating plate to throw off surface debris.

[0020] Preferably, the side surface of the main housing has a through-hole at the position of the two rotating rods, and the surface of the main housing has a discharge groove that communicates with the outside around the limiting baffle.

[0021] By adopting the above technical solution, the opening of the movable port provides space for the rotation of the rotating rod to prevent misalignment, while the discharge groove is located around the surface of the main housing to receive liquid and debris that fall off the surface of the material plate.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. Two movable clamps are used to hold and fix the material plate and rotate it longitudinally to perform the cleaning process. At the same time, through the disconnection and connection of the straight tooth surface and the helical tooth surface, when the movable clamps are no longer fixed to the material plate, the support plate drives the material plate to rotate laterally, thereby exposing the part of the material plate covered by the movable clamps to the outside. Then, the movable clamps fix and rotate the material plate, exposing the entire surface of the material plate for easy cleaning of the structure and ensuring thorough cleaning.

[0032] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0033] This application discloses a metal part surface treatment clamping structure.

[0034] The observation views of this device (front, rear, left, right) are attached. Figure 1 For reference.

[0035] Reference Figure 1 , Figure 2 A metal part surface treatment clamping structure includes a main housing 1. The upper end of the main housing 1 has a recess for containing the metal part. The bottom of the recess of the main housing 1 is surrounded by a discharge groove 8. One end of the discharge groove 8 is set as an inclined surface so as to be flush with the bottom surface of the recess of the main housing 1. The other end of the discharge groove 8 passes through the side surface of the main housing 1 and is connected to an external discharge pipe to receive liquid and debris dropped from the surface cleaning of the metal part. The front and rear ends of the top of the main housing 1 are provided with slots, and the two slots of the main housing 1 are connected to an external conveying device for the output and output of the metal part.

[0036] The main housing 1 is provided with clamping mechanisms 2 for clamping metal parts on both sides of the slot. The upper and lower ends of the clamping mechanism 2 extend from the side surface of the main housing 1 into the interior of the main housing 1. The side surface of the main housing 1 is provided with a movable opening 7 at the top of the clamping mechanism 2, so that the top of the clamping mechanism 2 extends into the recess of the main housing 1. The lower end surface of the main housing 1 is provided with a moving groove 10 from bottom to top, so that the bottom of the clamping mechanism 2 extends into the interior of the main housing 1.

[0037] Reference Figure 2 , Figure 3 , Figure 4The clamping mechanism 2 includes movable plates 21 movably disposed on both sides of the main housing 1. The two movable plates 21 are L-shaped in general, and the L-shaped bottom of the two movable plates 21 is located inside the movable groove 10. Threaded rods 25 are rotatably disposed at both ends of the inner wall of the movable groove 10. The L-shaped bottom of the two movable plates 21 is threadedly connected to the surface of the threaded rods 25. Rotating rods 23 are rotatably disposed on opposite sides of the top of the two movable plates 21. The two rotating rods 23 extend from the movable opening 7 into the recess of the main housing 1. Movable clamps 22 are fixedly disposed at opposite ends of the two rotating rods 23. A pressing groove 24 is opened inward on opposite surfaces of the two movable clamps 22. A cleaning material plate 3 is abutted in the pressing groove 24.

[0038] A second motor 14 is fixedly mounted on the outer surface of one of the movable plates 21. The output end of the second motor 14 movably passes through the side surface of the movable plate 21 and is fixedly connected to a rotating rod 23. Two alignment rods 4 are provided at both ends of the slot of the main housing 1 for each of the two movable clamps 22 (the spacing between the two alignment rods 4 is greater than the thickness of the material plate 3, and the material plate 3 is conveyed between the two alignment rods 4). All four alignment rods 4 movably pass through the interior of the movable clamps 22 and are distributed in pairs at the upper and lower ends of the movable clamps 22 (e.g., ...). Figure 3 As shown), the second motor 14 drives the rotating rod 23 so that when one of the moving clamps 22 rotates, the other moving clamp 22 rotates synchronously, and the four alignment rods 4 are fixed with bristles 6 at the position of the material plate 3. When the material plate 3 is entered into the recess of the main housing 1 by the external conveying device, it contacts the bristles 6 to assist in cleaning the surface of the material plate 3.

[0039] It should be noted that the groove shape of the clamping groove 24 is consistent with the shape of the material plate 3, and both sides of the groove of the clamping groove 24 are set as semi-circular arc surfaces, so that the two clamping grooves 24 are fixed when they abut against the material plate 3. At the same time, the thickness of the material plate 3 is half the height of the clamping groove 24, so that the material plate 3 can make a small range of longitudinal movement when it is laterally fixed by the two clamping grooves 24. The four alignment rods 4 are fixed with limiting rings 5 ​​on the inner and outer sides of the two moving clamps 22. The width of the limiting rings 5 ​​is greater than the width of the rod part of the alignment rods 4, thereby limiting the opposite movement range of the two moving clamps 22.

[0040] Reference Figure 3 , Figure 4 , Figure 5The threaded rod 25 is configured with a connecting smooth surface 29 in the middle, and one side of the surface of the connecting smooth surface 29 is interrupted, so that the threaded rod 25 is divided into left and right sides. An electromagnetic clutch 26 is provided at the split end of the connecting smooth surface 29. The stator end of the electromagnetic clutch 26 on the left side is fixedly connected to the left connecting smooth surface 29. The rotor end on the right side of the electromagnetic clutch 26 has a through hole in the middle that connects to the stator end. The right connecting smooth surface 29 moves through the rotor end and is fixedly connected to the stator end (the stator end and rotor end of the electromagnetic clutch 26 are normally in a disconnected state). The surface of the stator end of the electromagnetic clutch 26 is configured with a straight tooth surface 210. A spur gear 28 that meshes with the straight tooth surface 210 is provided on one side of the main housing 1 located in the moving groove 10. A first motor 13 is provided on one side of the spur gear 28. The output end of the first motor 13 is fixedly connected to the middle of the side surface of the spur gear 28.

[0041] A limiting baffle 9 is provided at the center of the bottom of the recess of the main housing 1. The limiting baffle 9 is ring-shaped. The main housing 1 is connected to the moving groove 10 at the center of the limiting baffle 9 and has a through opening. A helical gear 27 is rotatably arranged in the through opening. The tooth surface of the helical gear 27 is located in the moving groove 10. At the same time, the rotor end surface of the electromagnetic clutch 26 is provided with a helical tooth surface 211, which meshes with the tooth surface of the helical gear 27.

[0042] A ring protrudes from the rotating part of the helical gear 27 and is rotatably connected to the through-hole, thereby keeping the helical gear 27 rotating laterally within the through-hole and simultaneously limiting the helical gear 27 longitudinally. An electric push rod 11 is placed inside the limiting baffle 9. The housing of the electric push rod 11 is in a movable abutment state with the bottom surface of the limiting baffle 9, and the bottom of the housing of the electric push rod 11 is in a fixed state with the top of the helical gear 27. A support plate 12 is fixedly provided at the output end of the electric push rod 11. The support plate 12 is in a disc state, and a rubber layer is provided on the upper surface of the support plate 12 to increase the friction with the material plate 3. The electric push rod 11 is normally in an extended state, so that the upper surface of the support plate 12 abuts against the bottom of the material plate 3.

[0043] The limiting baffle 9 completely surrounds the housing of the electric actuator 11, while the diameter of the support plate 12 is larger than the width of the limiting baffle 9 (e.g., Figure 4 As shown in the figure, this shields the area around and top of the electric actuator 11, preventing liquid from the surface of the material plate 3 from falling into the electric actuator 11 and causing a short circuit.

[0044] The device also includes an electromagnetic clutch 26, an electric actuator 11, a first motor 13, and a second motor 14, all of which are existing technologies. Their structural principles will not be described in detail here. A PLC logic control system is added to coordinate and regulate the operating status of the electromagnetic clutch 26, the electric actuator 11, the first motor 13, and the second motor 14. Sensor monitoring components are added to the wiring connection terminals of the electromagnetic clutch 26, the electric actuator 11, the first motor 13, and the second motor 14 and connected to the PLC logic control system circuit to adjust the system's actions in a timely manner and avoid overload or jamming of multiple moving components.

[0045] The implementation principle of the metal part surface treatment clamping structure in this application embodiment is as follows: When using this device, the material plate 3 is transported to the recess of the main housing 1 by the external conveying device. At this time, the surface of the material plate 3 is separated from the conveyor belt of the conveying device at one end and enters between the two rear alignment rods 4, thereby forming an auxiliary support to maintain the balanced conveying of the material plate 3. When the material plate 3 moves to the center of the support plate 12, the first motor 13 drives the spur gear 28 to rotate. The spur gear 28 is connected by meshing with the spur tooth surface 210, thereby causing the stator end of the electromagnetic clutch 26 to rotate, which in turn causes the threaded rods 25 on both sides to rotate. As the threaded rods 25 rotate, the two moving plates 21 move towards each other along the surface of the threaded rods 25, shortening the distance between the two moving clamps 22, so that the two sides of the material plate 3 enter the clamping groove 24 and abut against the arc-shaped inner wall of the clamping groove 24 to form a lateral fixation.

[0046] At the same time, as the moving clamp 22 moves, when the two ends of the material plate 3 initially enter the range of the clamping groove 24, the control system controls the extension end of the electric push rod 11 to retract, thereby canceling the support of the support plate 12 on the material plate 3. The bottom of the material plate 3 loses support and slides down from the top of the inner wall of the clamping groove 24, thereby leaving a space reserved on the top of the material plate 3 covered by the clamping groove 24. At this time, the external cleaning structure sprays cleaning liquid on the surface of the material plate 3, and some liquid flows from the top of the material plate 3 into the reserved space, thereby cleaning the surface of the material plate 3.

[0047] While the cleaning mechanism is cleaning, the second motor 14 rotates and drives the rotating rod 23 to rotate, thereby causing the moving clamp 22 on one side to rotate longitudinally. The other moving clamp 22 rotates synchronously through the connection of the alignment rod 4, thereby causing the material plate 3 to flip over so that the back of the material plate 3 can be cleaned. At the same time, the residual liquid debris on the surface is poured into the recess of the main housing 1. The liquid debris is discharged to the outside through the discharge groove 8. Then, when the material plate 3 rotates to the horizontal, the electric push rod 11 extends and drives the support plate 12 for support.

[0048] When the pallet 12 comes into contact with the material plate 3, the control system regulates the electromagnetic clutch 26 to be in the connected state. At this time, the output end of the first motor 13 rotates in the reverse direction, thereby causing the two moving clamps 22 to release the clamp on the material plate 3. Then, the stator end and the rotor end of the electromagnetic clutch 26 are connected to make the helical tooth surface 211 rotate, which drives the helical gear 27 to rotate. This causes the electric push rod 11 to lift the material plate 3 from the pallet 12 and rotate 90°, completely exposing the obscured part of the material plate 3. Then, the electric push rod 11 is retracted and the moving clamps 22 are moved again to perform a second cleaning of the material plate 3. This completes the all-round cleaning of the material plate 3, preventing the material plate 3 from being obscured by the clamping and covering parts, which would cause incomplete cleaning.

[0049] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art.
