[0002] The cutting ring, also known as the wear ring, is an important component of a trailer concrete pump. It is a core component of the distribution valve system, primarily functioning to form a sealing pair with the spectacle plate, achieving dynamic sealing during reciprocating oscillation. Simultaneously, it can cut and break hard objects, preventing pipe blockage.

[0003] Due to the working environment of the cutting ring, the inner and outer rings are often subjected to friction. Therefore, wear-resistant layers are often welded onto the inner and outer rings of the cutting ring to improve its wear resistance.

[0004] In existing technologies, the welding process for cutting rings is primarily done manually by workers, resulting in very low automation and extremely low production efficiency. The core issue in the welding process of cutting rings is the positioning device.

[0015] In summary, the present invention has the following beneficial effects: 1. The present invention provides a crossbar forming a placement frame for a cutting ring; after the cutting ring is placed on the placement frame, each crossbar can fit against the inner ring of the cutting ring to achieve positioning of the cutting ring. A flat plate is fixed between each crossbar, and a pair of guide blocks are fixed on the flat plate. A slide bar is set through the guide blocks and slides together.

[0020] Figure 9 The cutting ring 17, which is to be welded, has a hollow ring structure with an inner and outer ring on one side. A groove is formed between the inner rings to accommodate a rubber spring. Figure 8 The two locations to be welded are marked on the top: the inner surface of the inner ring and the outer surface of the outer ring.

[0021] Combined with appendix Figures 1-8 The aforementioned cladding welding device for cutting rings of trailer pumps includes a welding station 10, on which a first vertical plate 18 and a second vertical plate 19 are fixed. At least three crossbars 33 are fixed on the first vertical plate 18 and the second vertical plate 19, and all the crossbars 33 form a placement frame for the cutting ring 17. It should be noted that after the cutting ring 17 is placed on the placement rack, each of the crossbars 33 can fit against the inner ring of the cutting ring 17 to achieve positioning of the cutting ring 17. A plate 37 is fixed between each of the crossbars 33, and a pair of guide blocks 42 are fixed on the plate 37. A slide bar 41 is set through the guide block 42. The slide bar 41 slides with the slide bar 42. A connecting piece 44 is fixed at one end of the slide bar 41. A spring 43 is fixed between the connecting piece 44 and the guide block 42. A handle 45 is fixed at one end of the connecting piece 44. A double inclined block 40 is fixed at the outer end of the slide bar 41. The double inclined block 40 is used to abut against the inner ring of the outermost cutting ring 17. Each of the crossbars 33 is slidably provided with a pusher 35, and the pushers 35 are fixed together by a connecting plate 36. Each pusher 35 is fixed to the first vertical plate 18 by a second spring 34. Each pusher 35 is used to abut against the outer ring of the innermost cutting ring 17, and the second spring 34 is in a compressed state. An electric slide rail 12 is also fixedly installed on the welding station 10. An electric slide table 13 is installed on the electric slide rail 12. A clamping assembly and a rotating assembly for driving the clamping assembly to rotate are installed on the electric slide table 13. An automatic plasma welding device is also provided between the electric slide rail 12 and the flat plate 37; The welding station 10 is fixed with an integrated electrical control box 11. When welding is to be performed on the cutting ring, the electric slide table 13 is moved to the designated position by the integrated electrical control box 11. The outermost cutting ring 17 is clamped by the clamping assembly. Then, the integrated electrical control box 11 controls the electric slide table 13 to reset. During the reset process, the clamping assembly pulls out a single cutting ring 17. During the pulling out of the cutting ring 17, the cutting ring 17 will push the double inclined block 40, thereby pushing the slide bar 41 to move towards the center. The spring 43 will be stretched. After the outermost cutting ring 17 is pulled out, the spring 43 will reset to block the next cutting ring 17. When a single cutting ring 17 is pulled out, the second spring 34 will return to its original position, pushing the pusher 35 to move, thereby pushing all the cutting rings 17 to move until the next cutting ring 17 abuts against the double inclined block 40. After the electric slide table 13 is reset, the rotating component drives the clamping component to rotate, thereby causing the clamped cutting ring 17 to rotate. In conjunction with the automatic plasma welding equipment, the inner and outer rings of the cutting ring 17 are automatically welded. The overall automation level is very high, minimizing the involvement of workers, saving labor, and enabling continuous welding, which improves efficiency and saves time.

[0022] It should be noted that the rotating assembly includes a column 14 fixed on the electric slide table 13, a crossbeam 15 fixed on the column 14, a motor base 46 fixed on the crossbeam 15, a motor 47 fixed on the motor base 46, the motor shaft of the motor 47 being fixed to a gear 48, the gear 48 meshing with a gear 49, the gear 49 being fixedly mounted on a rotating shaft 50, the rotating shaft 50 being rotatably mounted at one end of the crossbeam 15, and the clamping assembly being fixed at one end of the rotating shaft 50.

[0023] The integrated control box 11 contains a control program used to control the operation of each electrical appliance. Example 2

[0024] The difference between this embodiment and Embodiment 1 is that the clamping assembly includes a base plate 27 fixed to one end of the rotating shaft 50, a slide rail 28 fixed on the base plate 27, a threaded rod 31 rotatably disposed inside the slide rail 28, the threaded rod 31 being fixed to the motor shaft of the power motor 29, the power motor 29 being fixed on the slide rail 28, two threaded blocks 30 being slidably installed inside the slide rail 28, both of the threaded blocks 30 being threadedly engaged with the threaded rod 31, and a clamping block 32 being fixed on the threaded block 30.

[0025] It should be noted that the threaded rod 31 has two opposite threads and each of them engages with one of the threaded blocks 30. When the power motor 29 drives the rotation, the two threaded blocks 30 will move closer to each other, thereby bringing the two clamping blocks 32 closer together and achieving clamping.

[0026] In particular, the clamping block 32 is arc-shaped and has the same curvature as the inner circle of the groove on the cutting ring 17. When clamping, the two clamping blocks 32 extend into the groove on the cutting ring 17 and fit against the inner circle of the groove, making the clamping effect very stable.

[0027] Two fixing plates 39 are fixedly installed on the plate 37. A stop 38 is rotatably installed between the two fixing plates 39. When placing a batch of cutting rings 17 on the placement rack, pull the two handles 45 inward and rotate the stop 38 to put the two handles 45 inside. In this way, the two handles 45 will be blocked by the stop 38. The double inclined block 40 will no longer block the cutting rings 17 at this time, and many cutting rings 17 can be installed at one time very conveniently. After installation, rotate the stop 38, the spring 43 will return to its original position, and the double inclined block 40 will automatically block the cutting rings 17.

[0028] The automatic plasma welding equipment is a three-degree-of-freedom device, which includes an electric slide rail 16 fixed on the welding table 10, an electric slide table 21 slidably mounted on the electric slide rail 16, an electric slide rail 22 fixedly mounted on the electric slide table 21, an electric slide table 26 slidably mounted on the electric slide rail 22, a welding seat 23 fixed on the electric slide table 26, an automatic plasma welding torch 24 rotatably mounted on the clamping block 32, and a rotating motor 25 fixed to the welding seat 23 on one side of the automatic plasma welding torch 24. The rotating motor 25 is used to drive the automatic plasma welding torch 24 to rotate. An automatic welding wire supply device 20 is also fixed on the welding station 10. The automatic welding wire supply device 20 is used to automatically supply welding wire to the automatic plasma welding gun 24.

[0029] How to use: When welding the cutting ring 17, the electric slide table 13 is controlled by the integrated electrical control box 11 to move on the electric slide rail 12, so that the two clamping blocks 32 are inserted into the groove of the outermost cutting ring 17. Then, the integrated electrical control box 11 controls the power motor 29 to start, and the power motor 29 drives the threaded rod 31 to rotate. The threaded connection between the threaded rod 31 and the threaded block 30 drives the two threaded blocks 30 to move closer to each other. The threaded blocks 30 drive the clamping blocks 32 to move, and the two clamping blocks 32 clamp the outermost cutting ring 17. After clamping is completed, the integrated electrical control box 11 controls the electric slide table 13 to reset and moves the outermost cutting ring 17 through the clamping assembly. During the movement, the outermost cutting ring 17 pushes the double inclined block 40, thereby pushing the slide bar 41 to move towards the center. The spring 43 will be stretched. After the outermost cutting ring 17 is pulled out, the spring 43 will reset and block the next cutting ring 17. Then, the integrated electrical control box 11 controls the electric slide table 21 to move on the electric slide rail 16, so that the automatic plasma welding gun 24 is aligned with the inner ring welding position of the cutting ring 17. Then, the integrated electrical control box 11 controls the motor 47 to start, and the motor 47 drives the gear 48 to rotate. The meshing of the gear 48 and the gear 49 drives the rotating shaft 50 to rotate, and the rotating shaft 50 drives the clamping assembly and the cutting ring 17 to rotate. Then, the integrated electrical control box 11 controls the electric slide table 26 to move a certain distance along the electric slide rail 22 and controls the automatic plasma welding gun 24 to start. The automatic plasma welding gun 24 performs welding on the inner ring of the cutting ring 17. After a certain period of time, the integrated electrical control box 11 controls the electric slide table 26 to continue moving a certain distance along the electric slide rail 22, thereby successively performing welding on all positions of the inner ring of the cutting ring 17. After the inner ring of the cutting ring 17 is welded, the integrated electrical control box 11 controls the electric slide table 26 to reset, and then controls the rotary motor 25 to start. The rotary motor 25 drives the automatic plasma welding gun 24 to rotate to the position aligned with the outer ring of the cutting ring 17 for welding. Similarly, the integrated electrical control box 11 controls the gradual movement of the electric slide table 26 and cooperates with the opening of the automatic plasma welding gun 24 to perform welding. After the overall welding is completed, the integrated electrical control box 11 controls the automatic plasma welding gun 24 to turn off and controls the rotary motor 25 to start and drive the automatic plasma welding gun 24 to reset. Then, it controls the electric slide table 26 to reset and controls the electric slide table 21 to reset. The integrated electrical control box 11 then controls the power motor 29 to start, causing the two threaded rods 31 to reset and loosen the welded cutting ring 17. At this time, the operator can remove the welded cutting ring 17. After removal, the next automatic welding operation can be carried out through the integrated electrical control box 11.

They should not be construed as limiting the scope of protection of the present invention.
