Description

Technical Field

[0001] This utility model relates to the field of center bracket technology, specifically a machine tool center bracket. Background Technology

[0002] A machine tool center support is a device used to fix workpieces during machining. It is usually installed at the center of the machine tool spindle to support the workpiece during machining, keep it stable, ensure the machining accuracy and quality of the workpiece, and reduce bending and vibration caused by excessive length or insufficient rigidity of the workpiece. It is especially important for ensuring the machining accuracy of long shaft parts in turning.

[0003] Existing center supports are typically installed based on the lathe's spindle center, usually on the lathe's worktable. The support provides stable support for the workpiece, ensuring machining accuracy. However, in practice, due to differences in lathe models and sizes, and varying spindle rotation radii, a suitable support needs to be selected. Since the support height is fixed and cannot be flexibly adjusted, requiring the use of supports tailored to different lathes, production costs increase. Furthermore, the inability to flexibly adjust the support according to the workpiece's radius reduces its practicality. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a machine tool center support that solves the problem that the support cannot be flexibly adjusted in terms of its height and support structure according to the rotation radius of the workpiece to be processed, thus failing to adapt quickly and flexibly and leading to increased production costs.

The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0033] like Figures 1 to 6As shown, this embodiment of the utility model provides a machine tool center support, including a base plate 1, a movable seat 11 above the base plate 1, two symmetrical hydraulic telescopic columns 12 fixedly connected to the upper end face of the movable seat 11, and a support rod 13 fixedly connected to the movable ends of the two hydraulic telescopic columns 12. By extending the two hydraulic telescopic columns 12, the support rod 13 can be flexibly raised and lowered to control the working height of the support rod 13. A movable groove 14 is opened on the upper end face of the support rod 13, and two symmetrical movable blocks 15 are slidably connected in the movable groove 14. A movable plate 16 is fixedly connected to the upper end face of the movable block 15, a fixed block 17 is fixedly connected to the upper end face of the movable plate 16, and a fixed frame 18 is fixedly connected to the upper end face of the fixed block 17. A rotatable support is rotatably connected to the fixed frame 18. Support rollers 19 and support rods 13 are fixedly connected to a first positioning plate 20 on one side. A first forward / reverse motor 21 is fixedly connected to the upper surface of the first positioning plate 20. The output end of the first forward / reverse motor 21 is connected to a rotating shaft 22. A bidirectional screw 23 is fixedly connected to the end of the rotating shaft 22 away from the first forward / reverse motor 21. The bidirectional screw 23 is screwed to the moving block 15. With the operation of the first forward / reverse motor 21, the rotating shaft 22 drives the bidirectional screw 23 to be screwed, thereby screwing the bidirectional screw 23 to the moving block 15. This allows for rapid adjustment of the distance between the support rollers 19 on the two fixed frames 18. A first guide block 31 and a second guide block 32 are fixedly connected to both sides of the moving plate 16. The two first guide blocks 31 are slidably connected together. A first guide rod 33 and two second guide blocks 32 are slidably connected by a second guide rod 34. Positioning blocks 35 are fixedly connected to both ends of the first guide rod 33 and the second guide rod 34. The positioning blocks 35 are fixedly connected to the support rod 13. In conjunction with the use of the two first guide blocks 31, the two second guide blocks 32, the first guide rod 33, and the second guide rod 34, the two moving plates 16 can be guided, ensuring sufficient stability of the moving plates 16 during movement. A groove 41 is provided on the lower end face of the moving base 11, and a slide rail 42 is slidably connected within the groove 41. The slide rail 42 is fixedly connected to the base plate 1. The use of the groove 41 and the slide rail 42 allows for sliding guidance of the moving base 11, ensuring its stability. A groove 41 is provided on the upper end face of the base plate 1. The system includes an adjustment groove 51, within which an adjustment block 52 is slidably connected. The adjustment block 52 is fixedly connected to the movable seat 11. A second positioning plate 61 is fixedly connected to one side of the base plate 1. A second forward / reverse motor 62 is fixedly connected to the upper surface of the second positioning plate 61. A screw rod 63 is connected to the output end of the second forward / reverse motor 62. The screw rod 63 is rotatably connected to the base plate 1 and screwed to the adjustment block 52. Through the operation of the second forward / reverse motor 62, the screw rod 63 is screwed to the adjustment block 52, thereby allowing the adjustment block 52 to move flexibly along with the movable seat 11, sliding on two slide rails 42. Two symmetrical fixed posts 71 are fixedly connected to the upper surface of the movable seat 11. A connecting rod 72 is slidably connected to the fixed posts 71 and fixedly connected to the support plate.The use of two fixed posts 71 and their corresponding connecting rods 72 guides the support rod 13, ensuring sufficient stability during lifting and lowering. A limit groove 81 is provided within the fixed post 71, and a limit block 82 is slidably connected within the limit groove 81. The limit block 82 is fixedly connected to the connecting rod 72. The use of the limit groove 81 and the limit block 82 ensures that the connecting rod 72 can slide between itself and the fixed post 71 without detaching from it, thus maintaining the stability of the support rod.

[0034] The working principle and usage process of this utility model are as follows: First, the hydraulic telescopic column 12 extends, raising the support rod 13 to a suitable height. Simultaneously, the operation of the first forward / reverse motor 21 causes the rotating shaft 22 to rotate, driving the bidirectional screw 23. The bidirectional screw 23 is then screwed into two moving blocks 15, causing the moving blocks 15 to move along with the fixed blocks 17 and fixed frames 18 on the moving plate 16. This controls the distance between the two support rollers 19, providing stable support for the workpiece. Furthermore, the operation of the second forward / reverse motor 62 causes the spiral rod 63 to screw into the adjusting block 52, allowing the adjusting block 52 to slide along the moving seat 11 on the two slide rails 42, thus controlling the position of the moving seat 11. This completes the entire process of using the machine tool center support.
