Abstract
Description
Technical Field
[0001] This utility model relates to the field of rolling mill rolls, specifically a rolling mill roll used for precision machining. Background Technology
[0002] Rolls are the main working parts and tools on a rolling mill that cause continuous plastic deformation of metal;
[0003] Rollers need to be adjustable in the precision processing of materials, but existing rolls are lacking in stability of adjustment. Utility Model Content
[0004] The purpose of this invention is to provide a roll for precision machining to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A precision-machined roll includes a support frame. The outer wall of the support frame has a groove, and a bearing seat is slidably connected to the center of the groove. A connecting seat is installed on the top of the bearing seat, and a rotating shaft is fixedly connected to the top of the connecting seat. A worm gear seat is installed on the outer wall of the rotating shaft, and a worm gear is installed on the upper surface of the worm gear seat. The worm gear shaft is fixedly connected to the outer wall of the rotating shaft, and a worm is engaged with the outer wall of the worm gear. One end of the worm is fixedly connected to a rotating shaft.
[0007] As a further embodiment of this utility model: the top of the worm gear seat two is fixedly connected to the worm gear seat one, and a top cylinder is installed at the axial center of the worm gear seat one, and the inner cavity of the top cylinder is rotatably connected to the rotating shaft.
[0008] As a further embodiment of this utility model: the number of support frames is two sets, and a docking block is fixedly connected to the upper part of the two sets of support frames. A support plate is fixedly connected to the inner side of the docking block, and a connecting column is installed on the upper surface of the support plate. The bottom of the connecting column penetrates the upper surface of the support plate and is equipped with a damping spring. A bearing seat mounting plate is fixedly connected to the bottom of the damping spring, and the bearing seat mounting plate is fixedly connected to the inner side of the bearing seat.
[0009] As a further embodiment of this utility model: a second bearing seat is provided below the first bearing seat, an upper shaft column is rotatably connected to the central part of the first bearing seat, and a lower shaft column is rotatably connected to the central part of the second bearing seat.
[0010] As a further improvement of this utility model, an outer cylinder is fixedly connected to the upper part of the slot of the support frame.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] This utility model controls the rotation of a rotating shaft, which in turn drives a worm gear to rotate. The worm wheel, meshed on the outer wall of the worm gear, rotates, and the rotating shaft fixed at the center of the worm wheel drives the first bearing seat to rotate. However, the first bearing seat is limited by a slot on the side of the support frame, and the first bearing seat is slidably connected to the slot on the side of the support frame. Therefore, the first bearing seat does not rotate with the rotation of the rotating shaft, but only slides up and down at the slot on the side of the support frame, thus achieving the adjustment of the distance between the first bearing seat and the second bearing seat. Its structure is more optimized and its design is more reasonable. Attached Figure Description

[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. 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.
[0018] Please see Figures 1-3 In this embodiment of the present invention, a precision-machined roll includes a support frame 1. The outer wall of the support frame 1 has a groove, and a bearing seat 4 is slidably connected to the center of the groove. A connecting seat is installed on the top of the bearing seat 4, and a rotating shaft is fixedly connected to the top of the connecting seat. A worm gear seat 13 is installed on the upper part of the outer wall of the rotating shaft. A worm gear 12 is installed on the upper surface of the worm gear seat 13. The axial part of the worm gear 12 is fixedly connected to the outer wall of the rotating shaft. A worm 11 meshes with the outer wall of the worm gear 12, and a rotating shaft 10 is fixedly connected to one end of the worm 11.
[0019] Worm gear seat 13 is fixedly connected to the top of worm gear seat 13. A top cylinder 3 is installed at the axial center of worm gear seat 13. The inner cavity of the top cylinder 3 is rotatably connected to the rotating shaft.
[0020] There are two sets of support frames 1. A connecting block 8 is fixedly connected to the upper part of the two sets of support frames 1. A support plate is fixedly connected to the inner side of the connecting block 8. A connecting column 9 is installed on the upper surface of the support plate. The bottom of the connecting column 9 penetrates the upper surface of the support plate and is equipped with a damping spring 14. A bearing seat mounting plate 15 is fixedly connected to the bottom of the damping spring 14. The bearing seat mounting plate 15 is fixedly connected to the inner side of the bearing seat 4.
[0021] Bearing housing 2 is provided below bearing housing 4. The upper shaft column 6 is rotatably connected to the axial part of bearing housing 4, and the lower shaft column 7 is rotatably connected to the axial part of bearing housing 2.
[0022] An outer cylinder 16 is fixedly connected to the upper part of the slot of the support frame 1.
[0023] The working principle of this utility model is as follows:
[0024] In use, the control shaft 10 is rotated, which drives the worm 11 to rotate. The worm wheel 12 meshing with the outer wall of the worm 11 will rotate. The rotating shaft fixed at the center of the worm wheel 12 will drive the bearing seat 4 to rotate. However, the bearing seat 4 is limited by the slot opened on the side of the support frame 1. At the same time, the bearing seat 4 is slidably connected to the slot on the side of the support frame 1. Therefore, the bearing seat 4 will not rotate with the rotation of the rotating shaft, but will only slide up and down at the slot on the side of the support frame 1, thereby realizing the distance adjustment between the bearing seat 4 and the bearing seat 5.
[0025] A connecting block 8 is fixed between the two sets of support frames 1, and a support plate is fixed on the inner side of the connecting block 8 for assembling the damping spring 14 that is locked to the bottom of the connecting column 9. The bearing seat mounting plate 15 fixed to the bottom of the damping spring 14 is installed between the two sets of bearing seats 4, and is used to ensure the smooth displacement of the bearing seat 4 during the up and down displacement process.
[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
