Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The utility model discloses a metal product processing fixture. Figure 1-3 A metal product processing fixture comprises a processing table 1, a cavity 2 is provided inside the processing table 1, an electric push rod 3 is arranged on one side of the upper end of the processing table 1, a moving mechanism 4 is arranged inside the cavity 2 for assisting in clamping a circular tubular metal product, two connecting sleeves 5 are arranged on the moving mechanism 4, and a fixing mechanism 6 is arranged inside the connecting sleeve 5 for clamping and fixing the circular tubular metal product;

[0031] Reference Figure 2 and Figure 3 The moving mechanism 4 includes a gear 401, two tooth plates 402, two connecting blocks 403 and two moving plates 404. The gear 401 is rotatably arranged inside the cavity 2. The two tooth plates 402 are respectively meshed and arranged on the front and rear sides of the gear 401. The two connecting blocks 403 are respectively arranged at the upper ends of the corresponding tooth plates 402. The top ends of the connecting blocks 403 pass through the interior of the cavity 2. The two moving plates 404 are respectively arranged at the upper ends of the corresponding connecting blocks 403. One end of the connecting sleeve 5 is connected to the moving plate 404, and one end of the electric push rod 3 is connected to one side of the corresponding moving plate 404.

[0032] By adopting the above technical solution, when processing a circular tubular metal product, the electric push rod 3 works to push one of the movable plates 404 to move, and the movable plate 404 moves through the corresponding connecting block 403 to drive the corresponding tooth plate 402 to move, and the tooth plate 402 moves through the gear 401 to make the other tooth plate 402 move synchronously, so that the two movable plates 404 can be moved closer to or farther away from each other, and then the use position of the connecting sleeve 5 can be reasonably adjusted according to the length of the circular tubular metal product.

[0033] Reference Figure 3 The fixing mechanism 6 includes a threaded rod 601, a conical block 602, three inclined plates 603 and three clamping plates 604. The threaded rod 601 is threadedly arranged on one side of the connecting sleeve 5. One end of the threaded rod 601 passes through the movable plate 404, and the other end of the threaded rod 601 passes through the interior of the connecting sleeve 5. The conical block 602 is rotatably arranged at one end of the threaded rod 601 located inside the connecting sleeve 5. The three inclined plates 603 are all slidably arranged on the connecting sleeve 5, and one end of the inclined plate 603 passes through the interior of the connecting sleeve 5, which is used to clamp and fix the tubular metal product. The three clamping plates 604 are respectively arranged at one end of the corresponding inclined plate 603 located inside the connecting sleeve 5, and one end of the clamping plate 604 away from the inclined plate 603 is in contact with the conical block 602.

[0034] By adopting the above technical solution, after the two connecting sleeves 5 are respectively inserted into the inner sides of the two ends of the circular tubular metal product, the staff can rotate the threaded rod 601 to push the conical block 602 to move inside the connecting sleeve 5. The movement of the conical block 602 squeezes the clamping plate 604 to move the inclined plate 603, so that the inclined plate 603 can be abutted against the inner wall of the circular tubular metal product, so that the circular tubular metal product can be clamped and fixed without contacting the outer side surface of the circular tubular metal product.

[0035] Reference Figure 2 A slider 7 is provided on the side of the tooth plate 402 away from the gear 401, and a plurality of slide grooves 8 connected to the cavity 2 are opened inside the processing table 1. One end of the slider 7 away from the tooth plate 402 penetrates into the slide groove 8 and is slidably connected with the slide groove 8.

[0036] By adopting the above technical solution, when the tooth plate 402 moves, it will drive the slider 7 to slide in the slide groove 8, so that the tooth plate 402 moves more stably.

[0039] Working principle: When the utility model is in use, the electrical components appearing in the present application are all connected to an external power supply and a control switch. When processing a tubular metal product, the electric push rod 3 works to push one of the moving plates 404 to move. The moving plate 404 moves through the corresponding connecting block 403 to drive the corresponding tooth plate 402 to move. The tooth plate 402 moves through the gear 401 to make the other tooth plate 402 move synchronously, so that the two moving plates 404 can be moved closer to or farther from each other, so that the use position of the connecting sleeve 5 can be reasonably adjusted according to the length of the tubular metal product, so that the two connecting sleeves 5 can be moved closer to or farther from each other. The connecting sleeve 5 is respectively inserted into the inner side of both ends of the circular tubular metal product, and then the staff can rotate the threaded rod 601 to push the conical block 602 to move inside the connecting sleeve 5. The movement of the conical block 602 squeezes the clamping plate 604 to move the inclined plate 603, so that the inclined plate 603 can abut against the inner wall of the circular tubular metal product, so that the circular tubular metal product can be clamped and fixed without contacting the outer side of the circular tubular metal product, and then the surface of the circular tubular metal product does not need to be moved when processing its surface, and the surface processing of the circular tubular metal product will not be affected.

[0040] When the utility model is in use, it can not only stably clamp the round tubular metal product, but also does not contact the outer side surface of the round tubular metal product, so that the surface processing of the round tubular metal product is not affected.
