Description

Technical Field

[0001] This utility model relates to the field of automotive coating technology, and in particular to a flexible transition bracket for a coating conveyor line. Background Technology

[0002] In automotive painting production, the conveyor line is a key piece of equipment connecting pretreatment, electrophoresis, spraying and other processes. The transition bracket, as a connecting device between adjacent conveyor sections, directly affects the stability of the vehicle frame conveying and the painting quality.

[0003] Currently, most existing transition brackets in painting conveyor lines adopt a fixed structure design, with rigidly set support points and guide spacing. When designing and developing new vehicle models in the factory, the existing bracket support points may not align properly, necessitating bracket replacement and increasing factory costs. Therefore, to better adapt the transition bracket to various vehicle models, promote technological progress in the industry, and enhance core technological competitiveness, this application proposes a new implementation scheme that differs from existing flexible transition brackets in painting conveyor lines. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of low applicability of existing products, and to propose a flexible transition bracket for coating conveyor lines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A flexible transition bracket for a coating conveyor line includes a conveyor frame. Two mounting brackets are slidably connected to the top of the conveyor frame. Two connecting pipes are welded between the two mounting brackets. A double-rod hydraulic cylinder is fixedly connected to the bottom inner wall of the connecting pipe. One end of each hydraulic rod of the double-rod hydraulic cylinder is fixedly connected to a mounting block. The two mounting blocks are slidably inserted into both ends of the connecting pipe. A support frame is fixedly connected to the top of each mounting block. The top of the support frame has a groove, within which a support block is slidably connected. A positioning pin is welded to the top of each support block. A threaded rod is rotatably connected between the inner walls of both ends of the support frame. The support block is threadedly connected to the threaded rod, and a rotating handle is fixedly connected to one end of the threaded rod.

[0006] Furthermore, a rubber ring is fitted onto the outer wall of the mounting block, and the rubber ring contacts one end of the connecting pipe.

[0007] Furthermore, a storage battery is fixedly connected to the bottom inner wall of the connecting pipe, and the storage battery is connected to the double-rod hydraulic cylinder via a wire.

[0008] Furthermore, the top of the connecting pipe is provided with a through-hole, and a sealing cap is connected to one side of the inner wall of the through-hole by a hinge. The sealing cap is placed on the through-hole, and a sealing ring is fitted on the sealing cap. A control panel is fixedly connected to the inner side of the sealing cap, and the control panel is connected to the double-rod hydraulic cylinder by a wire.

[0009] Furthermore, a support rod is fixedly connected to one side of the support frame, and the other end of the support rod is fixedly connected to the bottom of the support frame.

[0010] Furthermore, a scale line is provided on one side of the support frame.

[0011] Furthermore, rubber plates are fixedly connected to the inner walls of both sides of the chute, and the rubber plates pass through the support block.

[0012] Furthermore, the bottom of the conveyor frame is fixedly connected with multiple support legs.

[0013] The beneficial effects of this utility model are as follows: 1. The distance between the two support frames is adjusted by extending or retracting the two hydraulic rods of the double-outlet hydraulic cylinder to accommodate frames of different widths. Then, turning the handle drives the threaded rod to rotate, thereby moving the positioning pin and adjusting the support position laterally to suit new models.

[0014] 2. Cover the chute with two rubber plates to prevent impurities from falling into the chute and affecting the movement of the support block. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 1-5 A flexible transition bracket for a painting conveyor line includes a conveyor frame 1, which serves as the core load-bearing frame. Two mounting brackets 3 are slidably connected to the top of the conveyor frame 1, and two connecting pipes 4 are welded between the two mounting brackets 3. A double-outlet hydraulic cylinder 7 is fixed to the bottom inner wall of the connecting pipe 4 by bolts. The double-outlet hydraulic cylinder 7 is model TOYOOKIHC1-W. One end of each of the two hydraulic rods of the double-outlet hydraulic cylinder 7 is fixed to a mounting block 6 by bolts. The two mounting blocks 6 are slidably inserted into the two ends of the connecting pipe 4, respectively. A support frame 11 is fixed to the top of the mounting block 6 by bolts. The two hydraulic rods of the double-outlet hydraulic cylinder 7 extend or retract to drive the mounting blocks 6 to move synchronously, thereby driving the support frame 11 to move and adjusting the distance between the two support frames 11 to suit different widths of vehicle frames. The top of the support frame 11 is provided with a sliding groove, and a support block 16 is slidably connected in the sliding groove. A positioning pin 17 is welded to the top of the support block 16. A threaded rod 15 is rotatably installed between the inner walls of both ends of the support frame 11 through an interlocking bearing. The support block 16 is threadedly connected to the threaded rod 15. The threaded rod 15 can be made of stainless steel and has a triangular thread or trapezoidal thread structure. One end of the threaded rod 15 is fixed with a rotating handle 19 by a bolt. Turning the rotating handle 19 drives the threaded rod 15 to rotate, thereby causing the support block 16 to move in the sliding groove, thereby driving the positioning pin 17 to move, and thus adjusting the support position laterally.

[0019] A locking nut can also be added to the threaded rod 15, so that the locking nut is between one end of the support frame 11 and the handle 19. When in use, screw in the locking nut so that it fits tightly against the outer wall of the support frame 11, thereby playing a positioning role. A rubber ring 5 is fitted onto the outer wall of the mounting block 6. The rubber ring 5 contacts one end of the connecting pipe 4. When the mounting block 6 retracts to its shortest distance, the rubber ring 5 seals the space between the mounting block 6 and the connecting pipe 4.

[0020] A battery 8 is fixed to the bottom inner wall of the connecting pipe 4 by bolts. The battery 8 is connected to the double-rod hydraulic cylinder 7 by wires, thereby providing power to the double-rod hydraulic cylinder 7.

[0021] The top of the connecting pipe 4 is provided with an opening. A sealing cover 9 is connected to the inner wall of one side of the opening by a hinge. The sealing cover 9 covers the opening to facilitate the maintenance of the double-rod hydraulic cylinder 7 and the battery 8. A sealing ring is fitted on the sealing cover 9 to seal the connection between the sealing cover 9 and the connecting pipe 4, thereby preventing water from entering. The control panel 10 is fixed to the inside of the sealing cover 9 by bolts. The control panel 10 is connected to the double-rod hydraulic cylinder 7 by a wire.

[0022] A support rod 12 is fixed to one side of the support frame 11 by bolts, and the other end of the support rod 12 is fixedly connected to the bottom of the support frame 11 to improve the sturdiness of the support frame 11.

[0023] The support frame 11 has a scale line 13 on one side, and the support block 16 moves along the scale line 13 to make precise adjustments to the support block 16.

[0024] Rubber plates 14 are fixed to the inner walls of both sides of the chute by bolts. The rubber plates 14 pass through the support block 16. The two rubber plates 14 cover the chute to prevent impurities from falling into the chute and thus affecting the movement of the support block 16. Lubricating oil can be added to the threaded rod 15 through the gap between the two rubber plates 14.

[0025] The bottom of the conveyor frame 1 is fixed with multiple support legs 2 by bolts, thereby providing stable support for the conveyor frame 1.

[0026] The working principle of this embodiment is as follows: When in use, first, open the sealing cover 9, and then control the double-rod hydraulic cylinder 7 to work through the control panel 10. The two hydraulic rods of the double-rod hydraulic cylinder 7 extend or retract to both ends respectively to drive the mounting block 6 to move synchronously, thereby driving the support frame 11 to move, and then adjusting the distance between the two support frames 11 to suit different widths of the frame. Then, turn the handle 19 to rotate the threaded rod 15, which causes the support block 16 to move in the groove, thereby moving the positioning pin 17. This allows for lateral adjustment of the support position so that the positioning pin 17 is aligned with the mounting hole of the frame. At the same time, the support block 16 moves along the scale line 13 to make precise adjustment. Then, tighten the locking nut at one end of the threaded rod 15 to fix the threaded rod 15 and prevent it from loosening. The groove is covered by two rubber plates 14 to prevent impurities from falling into the groove and affecting the movement of the support block 16. Then, the painted frame moves from the upstream conveyor line to between multiple support frames 11, and the mounting holes of the frame are inserted into the positioning pins 17 to provide stable support for the frame. The frame is then moved by the conveyor frame 1 to achieve a flexible transition.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
