Description

Technical Field

[0001] This application relates to the field of arc spraying technology, and more specifically, to an adjustable-angle consumable electrode clamping device for arc spraying. Background Art

[0002] Arc spraying is a thermal spraying process. An arc is generated between two energized metal electrodes (usually in the form of filaments or rods). The high temperature of the arc melts the electrode material, and then with the help of a high-speed compressed air flow (such as compressed air), the molten metal is atomized into tiny particles and sprayed onto the surface of the workpiece to form a coating. In arc spraying, a consumable electrode refers to an electrode that is melted and consumed by the arc as the coating material during the spraying process, usually a continuous metal wire or rod-shaped material.

[0003] In current arc spraying operations, most of the consumable electrode clamping devices have a fixed-angle structure, which is difficult to adapt to the spraying requirements of complex-shaped workpieces. When dealing with complex-shaped workpieces, the coating coverage is often incomplete and the thickness is inconsistent due to the limited electrode angle, thus affecting the spraying efficiency and operation continuity.

[0004] To solve the above problems, this application provides an adjustable-angle consumable electrode clamping device for arc spraying. Utility Model Content

[0005] An object of this application is to propose an adjustable-angle consumable electrode clamping device for arc spraying, including a support base. A vertical plate is fixedly connected to the top of the support base. Two limit plates are symmetrically and fixedly connected to the top of the vertical plate. Circular holes are opened on both of the two limit plates. A rotating rod is rotatably connected inside the two circular holes. A gear is fixedly connected to the outer side of the rotating rod. Fixed frames fixedly connected to both ends of the rotating rod are arranged outside the two limit plates. A sliding groove is opened on the top of the vertical plate. A sliding slot is opened on the inner bottom wall of the sliding groove. A sliding block is slidably connected inside the sliding slot. A sliding plate is slidably connected inside the sliding groove. A rack plate is fixedly connected to the top of the sliding plate. An electric push rod is fixedly connected to the outer side of the vertical plate. A limit frame is fixedly connected to the fixed frame. A screw rod is rotatably connected to the top of the limit frame. A connecting frame is slidably connected to the limit frame and is threadedly sleeved on the outer side of the screw rod. First semi-circular plates are fixedly connected to both ends of the connecting frame and on the fixed frame.

[0006] Further, the top end surface of the sliding block is fixedly connected to the bottom end surface of the sliding plate. The output end of the electric push rod is fixedly connected to the sliding block. The sliding plate is arranged in a "convex" shape structure.

[0007] Further, a support rod is fixedly connected to the outer side of the vertical plate. The electric push rod is fixedly connected to the top of the support rod. The sliding plate is arranged above the electric push rod.

[0008] Furthermore, the gear and rack plate are meshed and connected, the limiting frame has two sliding holes, and the connecting frame is slidably inserted into the two sliding holes. Both the limiting frame and the connecting frame are arranged in a "U" shape.

[0009] Furthermore, a second semicircular plate is inserted inside the first semicircular plate, and a third semicircular plate is inserted inside the second semicircular plate.

[0010] Furthermore, slots are symmetrically provided on the inner walls of the first, second, and third semicircular plates, and insertion rods are symmetrically fixedly connected to the outer walls of the second and third semicircular plates. The length of the slots is less than the length of the first semicircular plate.

[0011] Furthermore, each of the two first semicircular plates has a threaded hole, and a limiting screw is inserted into the threaded hole. The second and third semicircular plates also have limiting holes, and the limiting screw extends into the limiting hole.

[0012] The beneficial effects of this application are:

[0013] 1. Controlling the extension or retraction of the electric push rod can drive the sliding block to move inside the sliding groove. The movement of the sliding block drives the sliding plate to move inside the sliding groove. The movement of the sliding plate drives the rack plate to move. The movement of the rack plate drives the gear to rotate. The rotation of the gear drives the rotating rod to rotate, which in turn drives the fixed frame to rotate. This causes the structure holding the electrode wire on the fixed frame to rotate, so that the electrode wire can tilt upward or downward at a certain angle, thereby achieving precise angle adjustment.

[0014] 2. When the second semicircular plate is needed, it is inserted into the first semicircular plate through the cooperation of the slot and the insert rod. Then, the limiting screw inside the threaded hole is screwed into the limiting hole on the second semicircular plate to achieve limiting and fixing of the second semicircular plate. When the third semicircular plate is needed, it is similarly inserted into the second semicircular plate through the cooperation of the insert rod and the slot. Then, the limiting screw is screwed into the limiting hole on the third semicircular plate. The function of the first, second and third semicircular plates in conjunction with the third semicircular plate is to facilitate the limiting and clamping of electrode wires of different diameters, thereby increasing the applicability of the device.

[0026] Example:

[0027] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This application discloses an adjustable angle consumable electrode clamping device for arc spraying, including a support base 1. A vertical plate 2 is fixedly connected to the top of the support base 1. Two limiting plates 9 are symmetrically fixedly connected to the top of the vertical plate 2. Each limiting plate 9 has a circular hole. A rotating rod 10 is rotatably connected inside the two circular holes. A gear 11 is fixedly connected to the outside of the rotating rod 10. A fixing frame 3, fixedly connected to both ends of the rotating rod 10, is provided on the outside of the two limiting plates 9. A sliding groove 5 is provided on the top of the vertical plate 2. The inner bottom wall is provided with a sliding groove 6, and a sliding block 23 is slidably connected inside the sliding groove 6. A sliding plate 7 is slidably connected inside the sliding groove 5, and a rack plate 8 is fixedly connected to the top of the sliding plate 7. An electric push rod 4 is fixedly connected to the outside of the upright plate 2. Controlling the extension or retraction of the electric push rod 4 can drive the sliding block 23 to move inside the sliding groove 6. The movement of the sliding block 23 drives the sliding plate 7 to move inside the sliding groove 5. The movement of the sliding plate 7 drives the rack plate 8 to move, and the movement of the rack plate 8 drives the gear 11 to rotate. The rotation of wheel 11 drives the rotation rod 10 to rotate, which in turn drives the fixed frame 3 to rotate, thereby rotating the structure holding the electrode wire on the fixed frame 3. This allows the electrode wire to tilt upward or downward at a certain angle, thus achieving precise angle adjustment. A limit frame 12 is fixedly connected to the fixed frame 3. A lead screw 14 is rotatably connected to the top of the limit frame 12. A connecting frame 13 is slidably connected to the limit frame 12, and the connecting frame 13 is threaded onto the outside of the lead screw 14. A rotating handle is fixedly connected to the top of the lead screw 14. The outside of the rotating handle is provided with anti-slip texture. Twisting the rotating handle causes the connecting frame 13 to move inside the two sliding holes. The movement of the connecting frame 13 drives the first semicircular plate 15 connected to it to move, thereby gradually approaching the other first semicircular plate 15 until the self-consumable electrode wire located inside the two first semicircular plates 15 is clamped and limited, but not clamped tightly, so that the self-consumable electrode wire can move freely inside the two first semicircular plates 15. The two ends of the connecting frame 13 and the fixed frame 3 are all fixedly connected to the first semicircular plates 15.

[0028] Please see Figure 4The top surface of the sliding block 23 is fixedly connected to the bottom surface of the sliding plate 7. The output end of the electric push rod 4 is fixedly connected to the sliding block 23. The sliding plate 7 is set in a "convex" shape, thereby limiting and sliding the sliding plate 7 inside the sliding groove 5. A support rod is fixedly connected to the outside of the upright plate 2. The electric push rod 4 is fixedly connected to the top of the support rod. The support rod plays the role of fixing the electric push rod 4 to the upright plate 2. The sliding plate 7 is set above the electric push rod 4. The gear 11 and the rack plate 8 are meshed and connected. Two sliding holes are opened on the limiting frame 12. The connecting frame 13 is slidably inserted into the two sliding holes. Both the limiting frame 12 and the connecting frame 13 are set in a "U" shape.

[0029] Please see Figure 2 and Figure 3 A second semicircular plate 16 is inserted into the interior of the first semicircular plate 15, and a third semicircular plate 17 is inserted into the interior of the second semicircular plate 16. Slots 21 are symmetrically formed on the inner walls of the first, second, and third semicircular plates 15 and 16, respectively. Insert rods 22 are symmetrically fixedly connected to the outer walls of the second and third semicircular plates 16 and 17, respectively. The length of the slots 21 is less than the length of the first semicircular plate 15. Threaded holes 19 are formed on both first semicircular plates 15, and limiting screws 18 are threaded into the interior of the threaded holes 19. Limiting holes 20 are formed on both the second and third semicircular plates 16 and 17, and the limiting screws 18 extend into the interior of the limiting holes 20. When the second semicircular plate 16 is needed, it is inserted into the interior of the first semicircular plate 15 through the cooperation of the slots 21 and the insert rods 22, and then the limiting screws 18 inside the threaded holes 19 are screwed in to insert into the first semicircular plate 15. The limiting hole 20 on the second semicircular plate 16 is used to limit and fix the second semicircular plate 16. When the third semicircular plate 17 is needed, the third semicircular plate 17 is inserted into the second semicircular plate 16 through the cooperation of the insertion rod 22 and the slot 21. Then, the limiting screw 18 is screwed into the limiting hole 20 on the third semicircular plate 17. When screwing the limiting screw 18 into the limiting hole 20, it is not necessary to screw the limiting screw 18 into the inside of the second semicircular plate 16 or the third semicircular plate 17 to avoid affecting the clamping and limiting of the electrode wire. Similarly, when using the first semicircular plate 15, it is not necessary to screw the limiting screw 18 into the inside of the first semicircular plate 15. The function of the first semicircular plate 15, the second semicircular plate 16 and the third semicircular plate 17 is to facilitate the limiting and clamping of electrode wires of different diameters and increase the applicability of the device.

[0030] The implementation principle of this application embodiment is as follows: the self-consumable electrode wire is placed between two first semicircular plates 15, and the handle is turned to make the connecting frame 13 move inside the two sliding holes. The movement of the connecting frame 13 drives the first semicircular plate 15 connected to it to move, thereby gradually approaching the other first semicircular plate 15 until the self-consumable electrode wire located inside the two first semicircular plates 15 is clamped and limited, but the self-consumable electrode wire is not clamped tightly, so that the self-consumable electrode wire can move freely inside the two first semicircular plates 15.

[0031] The extension or retraction of the electric push rod 4 can drive the sliding block 23 to move inside the sliding groove 6. The movement of the sliding block 23 drives the sliding plate 7 to move inside the sliding groove 5. The movement of the sliding plate 7 drives the rack plate 8 to move. The movement of the rack plate 8 drives the gear 11 to rotate. The rotation of the gear 11 drives the rotating rod 10 to rotate, which in turn drives the fixed frame 3 to rotate. This achieves the rotation of the structure holding the electrode wire on the fixed frame 3, so that the electrode wire can be tilted up or down at a certain angle, thereby achieving precise angle adjustment.

[0032] When the second semicircular plate 16 is needed, it is inserted into the first semicircular plate 15 through the cooperation of the slot 21 and the insert rod 22. Then, the limiting screw 18 inside the threaded hole 19 is screwed into the limiting hole 20 on the second semicircular plate 16 to achieve the limiting and fixing of the second semicircular plate 16. When the third semicircular plate 17 is needed, it is also inserted into the second semicircular plate 16 through the cooperation of the insert rod 22 and the slot 21. Then, the limiting screw 18 is screwed into the limiting hole 20 on the third semicircular plate 17. When the limiting screw 18 is screwed into the limiting hole 20, it is not necessary to screw the limiting screw 18 into the inside of the second semicircular plate 16 or the third semicircular plate 17 to avoid affecting the clamping and limiting of the electrode wire. Similarly, when using the first semicircular plate 15, it is not necessary to screw the limiting screw 18 into the inside of the first semicircular plate 15.

[0033] The first semicircular plate 15, the second semicircular plate 16, and the third semicircular plate 17 work together to facilitate the limiting and clamping of electrode wires of different diameters, thereby increasing the applicability of the device.

[0034] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and application concept of this application, should be included within the scope of protection of this application.
