Description

Technical Field

[0001] The utility model belongs to the technical field of bushing processing and positioning, and specifically relates to a hollow bushing processing and positioning device. Background Art

[0002] A bushing is a cylindrical mechanical part sleeved on a rotating shaft and is a component of a sliding bearing. Generally, the bushing and the bearing seat are in interference fit, while the bushing and the shaft are in clearance fit. A bushing refers to the sleeve on a propeller shaft or a stern shaft, and a bearing is a component that plays a role in fixing and reducing the load friction coefficient during mechanical transmission. The similarity between a bushing and a bearing is that both bear the load of the shaft, and the difference is that the bushing is of an integral structure and there is relative movement between the shaft and the bushing during rotation; while the bearing is of a split structure and there is relative movement between the inner and outer rings of the bearing itself during rotation. However, essentially, the bushing is actually a type of sliding bearing. During the locomotive maintenance process of a fully suspended wheel set, the hollow bushing is one of the important components of the fully suspended wheel set.

[0003] When processing a hollow bushing, a positioning device is required to effectively position the hollow bushing to facilitate the processing of the hollow bushing.

[0004] At present, some hollow bushings in the existing technology are centered and fixed manually during processing. Manual centering may have certain deviations, thereby reducing the processing quality of the hollow bushing, and the hollow bushing cannot rotate after being fixed, thus making it inconvenient to perform some specified processing operations.

[0005] Therefore, a hollow bushing processing and positioning device is proposed for the above problems. Content of the Utility Model

[0006] In order to make up for the deficiencies of the existing technology and solve the problems of low processing quality and inability to rotate of the hollow bushing, a hollow bushing processing and positioning device is proposed.

An installation box is fixedly arranged on the upper end surface of the workbench. A motor one is fixedly arranged on the right side of the installation box. A bidirectional threaded rod is arranged inside the installation box. Two moving plates are sleeved on the outer side of the bidirectional threaded rod. A limiting rod is fixedly arranged on the upper end surface of the moving plate. An installation platform is arranged at the lower end of the workbench. A motor two is fixedly arranged on the upper end surface of the installation platform. The output end of the motor two is fixedly provided with a rotating shaft, and the other end of the rotating shaft is fixedly arranged on the lower end surface of the workbench.

[0008] Preferably, the output end of the motor one is fixedly connected to the right end of the bidirectional threaded rod, and the left end of the bidirectional threaded rod is installed on the left side inside the installation box.

[0009] Preferably, a threaded hole is formed in the right side of the moving plate, and the moving plate is in threaded connection with the bidirectional threaded rod through the threaded hole. The two moving plates are respectively sleeved on the threads on the left and right sides of the bidirectional threaded rod.

[0010] Preferably, a through groove is formed in the upper end surface of the mounting box, and the other end of the limiting rod is arranged on the upper end of the mounting box through the through groove.

[0011] Preferably, a rubber pad is fixedly arranged on the outer side of the limiting rod.

[0012] Preferably, an annular groove is formed in the upper end surface of the mounting table, four support rods are fixedly arranged on the lower end surface of the workbench, and the other ends of the support rods are arranged inside the annular groove.

[0013] Preferably, an installation groove is formed in the lower end surface of the annular groove, a ball is arranged inside the installation groove, and the lower end of the ball is arranged at the bottom inside the annular groove.

[0014] Advantages of the present utility model:

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0025] The following gives specific embodiments.

[0026] Please refer to Figures 1-3 , the present invention provides a processing positioning device for a hollow shaft sleeve, including a workbench 1. An installation box 2 is fixedly arranged on the upper end surface of the workbench 1. A first motor 3 is fixedly arranged on the right side of the installation box 2. A bidirectional threaded rod 4 is arranged inside the installation box 2. Two moving plates 5 are sleeved outside the bidirectional threaded rod 4. A limiting rod 8 is fixedly arranged on the upper end surface of the moving plate 5. An installation table 10 is arranged at the lower end of the workbench 1. A second motor 15 is fixedly arranged on the upper end surface of the installation table 10. The output end of the second motor 15 is fixedly provided with a rotating shaft 16. The other end of the rotating shaft 16 is fixedly arranged on the lower end surface of the workbench 1.

[0027] Furthermore, as Figure 2 shown, the output end of the first motor 3 is fixedly connected to the right end of the bidirectional threaded rod 4. The left end of the bidirectional threaded rod 4 is installed on the left side inside the installation box 2.

[0028] During operation, the first motor 3 is started, and the output end of the first motor 3 can drive the bidirectional threaded rod 4 to rotate.

[0029] Furthermore, as Figures 2-3 shown, a threaded hole 6 is opened on the right side of the moving plate 5. The moving plate 5 is threadedly connected to the bidirectional threaded rod 4 through the threaded hole 6. The two moving plates 5 are respectively sleeved on the threads on the left and right sides of the bidirectional threaded rod 4.

[0030] During operation, the opening of the threaded hole 6 facilitates the threaded connection between the moving plate 5 and the bidirectional threaded rod 4. When the bidirectional threaded rod 4 rotates, the moving plate 5 can move left and right under the action of the thread between the bidirectional threaded rod 4 and the threaded hole 6 and the limiting action of the installation box 2.

[0031] Furthermore, as Figure 1 shown, a through groove 7 is formed on the upper end surface of the mounting box 2, and the other end of the limiting rod 8 is arranged on the upper end of the mounting box 2 through the through groove 7.

[0032] During operation, the formation of the through groove 7 facilitates the arrangement of the limiting rod 8, and the limiting rods 8 on both sides can fix the inner wall of the hollow bushing.

[0033] Furthermore, as Figure 1 shown, a rubber pad 9 is fixedly arranged on the outer side of the limiting rod 8.

[0034] During operation, the arrangement of the rubber pad 9 can play a role in increasing the friction force, so that the limiting rod 8 can cooperate with the rubber pad 9 to play a better positioning and fixing effect on the inner wall of the hollow bushing.

[0035] Furthermore, as Figure 4 shown, an annular groove 11 is formed on the upper end surface of the mounting table 10, and four support rods 12 are fixedly arranged on the lower end surface of the workbench 1. The other end of the support rod 12 is arranged inside the annular groove 11.

[0036] During operation, the arrangement of the support rod 12 can support the workbench 1, and the support rod 12 arranged inside the annular groove 11 can limit it, so that the workbench 1 can rotate smoothly.

[0037] Furthermore, as Figure 4 shown, a mounting groove 13 is formed on the lower end surface of the annular groove 11, and a ball 14 is arranged inside the mounting groove 13. The lower end of the ball 14 is arranged at the bottom inside the annular groove 11.

[0038] During operation, the arrangement of the ball 14 has a rotating function, so that the support rod 12 can rotate inside the annular groove 11, and further can support the workbench 1.

[0039] Working principle: The operator puts the hollow shaft sleeve on the outside of the two limit rods 8, and then can start the first motor 3. The output end of the first motor 3 can drive the bidirectional threaded rod 4 to rotate. The two moving plates 5 move outward under the action of the bidirectional threaded rod 4 and the threads of the threaded holes 6. The moving plates 5 can drive the limit rods 8 to move outward, and the limit rods 8 can cooperate with the rubber pads 9 to position and fix the inner wall of the hollow shaft sleeve, thus facilitating subsequent processing; during the processing, the operator starts the second motor 15. The output end of the second motor 15 can drive the rotating shaft 16 to rotate, and the rotating shaft 16 can drive the workbench 1 to rotate, and then can drive the hollow shaft sleeve on the upper end of the workbench 1 to rotate, thus facilitating the processing of the hollow shaft sleeve; when the workbench 1 rotates, the support rods 12 and the balls 14 can rotate synchronously inside the annular groove 11, and the support rods 12 and the balls 14 can support the workbench 1, ensuring its stability during rotation.

[0040] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
