[0002] During the processing of copper tubes in metal products, the copper tubes need to be tested. During the test, the copper tube is fixed by a fixture. One end of the copper tube is fixed by the upper and lower arc-shaped clamps on the fixture.

At the same time, the copper tube is inconvenient to disassemble after fixing, which increases the difficulty of operation and labor intensity, affecting the overall work efficiency. This structural design is not conducive to batch testing and quick replacement, and it is difficult to meet the needs of efficient and convenient production testing. It is urgent to optimize and improve the fixture to enhance testing efficiency and ease of operation. Summary of the Invention

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution:

[0023] A copper tube testing fixture for copper tube processing includes two symmetrically arranged lower limit plates 1. A support frame 2 is fixedly installed between the two sets of limit plates 1. An inner cavity 3 is opened inside the limit plate 1. A gear 4 is rotatably connected inside the inner cavity 3. A rotating shaft 5 is fixedly installed between the two sets of gears 4. A motor 6 is fixedly installed on the lower end face of the inner side limit plate 1. The output shaft of the motor 6 is fixedly connected to the gear 4. Multiple limit grooves 8 are opened on the upper end face of the lower limit plate 1. The multiple limit grooves 8 are all interconnected with the inner cavity 3. A gear ring 7 is rotatably connected inside the limit groove 8. The gear ring 7 meshes with the gear 4. A slide rail 9 is fixedly installed on the inner wall of the gear ring 7. A slider 10 is slidably connected inside the slide rail 9. A guide groove 12 is fixedly installed on the lower end face of the inner side limit groove 8. A slide rod 11 is fixedly installed on the lower end face of the slider 10. The slide rod 11 is slidably connected to the guide groove 12.

[0024] A clamping plate 13 is fixedly installed on the outer surface of the slide bar 11, and an anti-slip pad is fixedly installed on the inner wall of the clamping plate 13.

[0025] Multiple sets of slide rail 19, slider 10, slide rod 11, guide groove 12 and clamping plate 13 are provided and arranged in a ring at intervals.

[0026] When multiple sets of copper tubes need to be fixed for testing, multiple sets of copper tubes are placed into the equipment through the limiting groove 8 on the upper cover plate 17. Then, the motor 6 is started to make gear 4 rotate. The two sets of gear 4 are fixedly connected by the rotating shaft 5, so the two sets of gear 4 rotate synchronously.

[0027] The gear ring 7 meshes with the gear 4, thus driving the gear ring 7 to rotate. The gear ring 7 simultaneously carries the slide rail 9 to move. The slider 10, which is slidably connected inside the slide rail, is fixedly connected to the slide rod 11, which is slidably connected inside the guide groove 12. Therefore, the displacement direction of the slide rod 11 is guided, so that the clamp 13, which is fixedly installed on the outer surface of the slide rod 11, is simultaneously pressed tightly against the copper tube. The upper and lower limit plates 1 both initially fix the copper tube.

[0028] A threaded rod 14 is rotatably connected to the upper end face of the upper limiting plate 1, and the thread groove on the outer surface of the threaded rod 14 is a one-way thread groove.

[0029] Gear 2 15 is fixedly installed on the outer surface of threaded rod 14, and gear 2 15 meshes with gear 1 4.

[0030] A limit plate 16 is fixedly installed on the upper end face of the support frame 2, and an upper cover plate 17 is provided on the upper side of the support frame 2.

[0031] The lower end face of the upper cover plate 17 is provided with a threaded hole 18 corresponding to the threaded rod 14, and a sliding sleeve 19 is fixedly installed on the outer surface of the upper cover plate 17 for the limiting plate 16.

[0032] After initial fixing, the upper cover plate 17 can be placed on the threaded rod 14, so that the threaded rod 14 and the threaded hole 18 on the upper cover plate 17 are connected by a screw drive. The gear 4 on the upper limit plate 1 meshes with the gear 15 on the threaded rod 14, so that the threaded rod 14 can rotate. The screw drive connection between the threaded rod 14 and the threaded hole 18 on the upper cover plate 17 allows the upper cover plate 17 to descend. In conjunction with the limit plate 1 at the bottom of the equipment, the copper tube is clamped and fixed for a second time, further strengthening the fixing effect. The combination of the sliding sleeve 19 and the limit plate 16 can guide and limit the upper cover plate 17.

[0033] Existing fixtures can only fix a single copper tube at a time, resulting in low testing efficiency and long operation time. Furthermore, the inconvenience of disassembling the fixed copper tube increases operational difficulty and labor intensity, impacting overall work efficiency. This structural design is not conducive to batch testing and rapid replacement, failing to meet the demands of efficient and convenient production testing. Optimization and improvement are urgently needed to enhance testing efficiency and operational convenience. Therefore, this utility model proposes a multi-set copper tube synchronous fixing and testing structure, enabling the simultaneous clamping and testing of multiple copper tubes, significantly improving testing efficiency. Simultaneously, the optimized fixing method enhances clamping stability, preventing copper tube loosening during testing. This effectively solves the problems of low single-operation efficiency and inconvenient disassembly / reassembly associated with traditional fixtures, improving the overall convenience and safety of the testing process.

[0034] Working principle: When multiple sets of copper tubes need to be fixed and tested, multiple sets of copper tubes are placed into the equipment through the limiting groove 8 on the upper cover plate 17. Then, the motor 6 is started to make gear 4 rotate. The two sets of gears 4 are fixedly connected by the rotating shaft 5, so the two sets of gears 4 rotate synchronously.

[0035] The gear ring 7 meshes with the gear 4, thus driving the gear ring 7 to rotate. The gear ring 7 simultaneously carries the slide rail 9 to move. The slider 10, which is slidably connected inside the slide rail, is fixedly connected to the slide rod 11, which is slidably connected inside the guide groove 12. Therefore, the displacement direction of the slide rod 11 is guided, so that the clamp 13, which is fixedly installed on the outer surface of the slide rod 11, is simultaneously pressed tightly against the copper tube. The upper and lower limit plates 1 both initially fix the copper tube.

[0036] After initial fixing, the upper cover plate 17 can be placed on the threaded rod 14, so that the threaded rod 14 and the threaded hole 18 on the upper cover plate 17 are connected by a screw drive. The gear 4 on the upper limit plate 1 meshes with the gear 15 on the threaded rod 14, so that the threaded rod 14 can rotate. The screw drive connection between the threaded rod 14 and the threaded hole 18 on the upper cover plate 17 allows the upper cover plate 17 to descend. In conjunction with the limit plate 1 at the bottom of the equipment, the copper tube is clamped and fixed for a second time, further strengthening the fixing effect. The combination of the sliding sleeve 19 and the limit plate 16 can guide and limit the upper cover plate 17.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
