[0023] 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. The described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.

[0024] Reference Figures 1-4An auxiliary clamp for heat-resistant steel castings includes a frame 1. A through groove 6 is formed at the top of the frame 1. A ring 5 is bolted to the through groove 6. A turntable 4 is rotatably connected to the top of the ring 5, and the turntable 4 is fixed to the ring 5 by a detachable pin assembly. The pin assembly includes a sliding sleeve 7, which is bolted to one outer wall of the ring 5. A first sliding groove 9 is formed at the top of the ring 5. A rod 10 is slidably connected inside the first sliding groove 9. A spring 8 is sleeved on the outside of the rod 10, and both ends of the spring 8 are respectively connected to the sliding groove 9. The sleeve 7 and the insert rod 10 are fixed together. The outer circumference of the turntable 4 has multiple insertion holes 11, and the insert rod 10 is inserted into the corresponding insertion hole 11. When it is necessary to adjust the position of the installed cylindrical heat-resistant steel casting, pull the insert rod 10, the spring 8 contracts, and the insert rod 10 moves out of the insertion hole 11. Then rotate the turntable 4 to move the cylindrical heat-resistant steel casting to a position convenient for subsequent processing. It is then re-fixed using the pin assembly for easy subsequent processing. The top of the turntable 4 has multiple guide grooves 22, and each guide groove 22 contains... A sliding connection is provided with a clamping plate 13. A round tube 12 is fixed to the upper surface of the turntable 4 by bolts. A threaded rod 17 is rotatably connected to the inner wall of the top of the round tube 12. A threaded ring 15 is threadedly connected to the outer side of the threaded rod 17. Multiple connecting rods 16 are rotatably connected to the outer side of the threaded ring 15, and the connecting rods 16 are rotatably connected to their corresponding clamping plates 13. A cavity 19 is provided inside the turntable 4. A power assembly for driving the threaded rod 17 to rotate is provided inside the cavity 19. The power assembly includes a worm gear 20, which is rotatably connected inside the cavity 19. The threaded rod 17... The bottom end extends into the cavity 19 and is keyed to a worm gear 18, which meshes with the worm 20. The hollow cylindrical heat-resistant steel casting is fitted onto the outer side between multiple clamping plates 13. Then, the worm 20 is rotated, causing the worm gear 18 to drive the threaded rod 17 to rotate, thereby causing the threaded ring 15 to move downward. This causes the connecting rod 16 to move and press the clamping plates 13 to move outward along the guide groove 22 until the clamping plates 13 support and clamp the cylindrical heat-resistant steel casting, making it convenient for workers to support and position cylindrical heat-resistant steel castings of different diameters.

[0025] In this utility model, it should be noted that a guide rod 21 is fixed in the guide groove 22 by bolts, and the clamping plate 13 is slidably connected to the guide rod 21. The guide rod 21 can guide the clamping plate 13 so that it can move stably. Multiple second sliding grooves 14 are opened on the outer side of the round tube 12, and the protrusion on the outer side of the threaded ring 15 slides along the second sliding groove 14. The second sliding groove 14 can guide the threaded ring 15 so that it can move up and down stably. Multiple discharge ports 3 are opened on the top of the frame 1. A collection box 2 is provided inside the frame 1, and the through groove 6 and the discharge ports 3 are both located above the collection box 2. The debris generated by the external instruments processing the cylindrical heat-resistant steel casting can fall into the collection box 2 through the discharge ports 3 and the through groove 6 for easy centralized processing. One end of the worm gear 20 extends out of the turntable 4 and is welded with a handle, which makes it convenient for the operator to rotate the worm gear 20.

[0026] The working principle of this utility model is as follows: When it is necessary to position a hollow cylindrical heat-resistant steel casting, the cylindrical heat-resistant steel casting is first placed on the outer side between multiple clamping plates 13. Then, the handle is turned, and the rotation of the handle causes the worm gear 20 to drive the worm wheel 18 to rotate, thereby causing the threaded rod 17 to rotate and drive the threaded ring 15 to move downward, causing the connecting rod 16 to move and press the clamping plates 13 to move outward along the guide groove 22, thereby allowing the clamping plates 13 to support and clamp the cylindrical heat-resistant steel casting, making it convenient for workers to position cylindrical heat-resistant steel castings of different diameters. When it is necessary to adjust the position of the installed cylindrical heat-resistant steel casting, the insertion rod 10 is pulled, the spring 8 retracts, and the insertion rod 10 moves out of the insertion port 11. Then, the turntable 4 is rotated, causing the cylindrical heat-resistant steel casting to move to a position that is convenient for subsequent processing. Then, it is fixed again by the pin assembly, which facilitates subsequent processing.
