[0002] The sleeve is a cylindrical mechanical part that is sleeved on the rotating shaft and is a component of the sliding bearing.

[0003] During the production and processing of the shaft sleeve, in order to ensure the stability of the shaft sleeve, a fixed device is used to limit the shaft sleeve. At present, the fixed device clamps the two ends of the shaft sleeve through a limit plate, and processes the shaft sleeve through the processing components on the fixed device. However, this processing method has the following shortcomings when used: the limit plate will be squeezed with the outer wall of the shaft sleeve when limiting the shaft sleeve, and this extrusion limit will cause the shaft sleeve port to deform, and the deformed shaft sleeve cannot be subsequently processed, resulting in excessive consumption of shaft sleeve resources; and because the processing position needs to be changed after one side of the shaft sleeve is processed, it is necessary to move the limit plate to the initial position, so that the limit plate can be disconnected from the shaft sleeve, and the shaft sleeve is manually flipped, and the limit plate is used again to limit the shaft sleeve, and the processing position of the shaft sleeve cannot be adjusted on the fixed equipment, thereby affecting the efficiency and level of the shaft sleeve processing. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-Figure 6 , a fixing device for processing a shaft sleeve, comprising a base 1, a processing table 2, and a processing component (the processing component is not shown in the drawings of the specification);

[0024] A sealing cover 3 is fixedly mounted on the base 1, and a sealing door 4 is symmetrically arranged on the sliding sleeve of the sealing cover 3. A through hole 5 extending into the base 1 is opened on the processing table 2. The sealing cover 3 is a circular structure with one side open, and the through hole 5 is vertically opened. The seal cover 3 and the sealing door 4 cooperate with each other to seal the shaft sleeve during the processing, so that the shaft sleeve debris will not affect the surrounding environment, and the safety of the operator during the operation is also guaranteed;

[0025] A hydraulic cylinder 6 is fixedly installed in the sealing cover 3, and a support plate 7 is fixedly connected to the output end of the hydraulic cylinder 6. A rotating shaft 8 extending into the central hole of the sleeve is rotatably installed on the support plate 7. The rotating shaft 8 is vertically arranged, and a gear 19 extending into the base 1 is fixedly installed on the rotating shaft 8;

[0026] A guide rod 20 is fixedly installed in the base 1, and a sliding sleeve on the guide rod 20 is provided with a rack 21 meshing with the gear 19, and an armrest is fixedly installed on the rack 21. By pulling the armrest, the rotating shaft 8 can drive the sleeve 13, the limit plate 16, and the sleeve to be pulled, and the sleeve can quickly change the processing position after rotation, so that the sleeve does not need to be manually turned over during processing, thereby improving the efficiency of sleeve processing;

[0027] A pressure plate 9 is provided on the sliding sleeve of the rotating shaft 8, a fixed sleeve 10 is fixedly installed on the pressure plate 9, a locking bolt detachably connected to the rotating shaft 8 is threadedly connected on the fixed sleeve 10, a soft pad 11 that is movably against the shaft sleeve is provided on the pressure plate 9, and a sleeve 13 is fixedly installed on the rotating shaft 8. By pressing the pressure plate 9, the pressure plate 9 and the soft pad 11 can press the shaft sleeve from the top position, so that the shaft sleeve is in a balanced state as a whole. It should be noted that when the limiting plate 16 limits the shaft sleeve, the pressure plate 9 is disconnected from the shaft sleeve and lifted, so that the pressure plate 9 does not come into contact with the shaft sleeve;

[0028] The sleeve 13 is connected to a limiting plate 16 for limiting the position of the sleeve through a connecting piece;

[0029] The connecting member includes a fixed rod 12 fixedly installed in a sleeve 13, and a symmetrically arranged fixed platform 14 is fixedly installed on the fixed rod 12, a symmetrically arranged sliding rod 15 is slidably sleeved in the fixed platform 14, and a limit plate 16 is arranged on the sliding rod 15, and the fixed platform 14 and the guide long hole guide the sliding rod 15, so that the sliding rod 15 can smoothly pull the limit plate 16 when moving;

[0030] A spring 17 is welded between the fixed platform 14 and the slide bar 15. The spring 17 has a buffering effect on the slide bar 15, so that when the output end of the telescopic rod 18 drives the slide bar 15 back to the initial position, it will not cause excessive impact on the fixed platform 14. The telescopic rod 18 connected to the slide bar 15 is fixedly installed on the fixed platform 14. The fixed rod 12 is vertically arranged in the sleeve 13, and the two fixed platforms 14 are horizontally arranged from top to bottom. The spring 17 is horizontally welded to a side position of the slide bar 15 extending to the inside of the fixed platform 14. The limit plate 16 and the slide bar 15 extend to a side position outside the sleeve 13, and the sleeve 13 is provided with a guide long hole for guiding the slide bar 15. The limit plate 16 is an arc-shaped structure adapted to the inner wall of the sleeve.

[0031] The sliding rod 15 drives the limiting plate 16 to extend outward from the sleeve 13 through the driving of the telescopic rod 18, so that the limiting plate 16 contacts the inner wall of the central hole of the sleeve to limit the sleeve, so that the sleeve will not be deformed when the limiting plate 16 limits the sleeve.

[0032] It should be noted that the specific models and specifications of the processing components, hydraulic cylinder 6, and telescopic rod 18 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0033] The functional principle of the utility model can be explained through the following operation modes:

[0034] Place the sleeve vertically on the processing table 2 so that the center hole of the sleeve can correspond to the through hole 5;

[0035] The output end of the hydraulic cylinder 6 drives the support plate 7, the rotating shaft 8, the pressure plate 9, the sleeve 13, and the gear 19 to move downward, so that the rotating shaft 8 drives the gear 19 to extend through the through hole 5 into the base 1, and at the same time, the rotating shaft 8 drives the sleeve 13 to extend into the center hole of the sleeve;

[0036] When the sleeve 13 extends into the center hole of the sleeve, the hydraulic cylinder 6 stops operating;

[0037] The pressure plate 9 is manually pressed, so that the pressure plate 9 drives the fixed sleeve 10 to slide on the rotating shaft 8. When the pressure plate 9 slides, the soft pad 11 is brought into contact with the top of the sleeve, so that the pressure plate 9 can ensure the stability of the sleeve from the top position;

[0038] The output ends of the four telescopic rods 18 simultaneously drive the four slide bars 15 to slide in the fixed platform 14. The spring 17 is stressed, so that the slide bars 15 drive the limit plate 16 to extend out of the sleeve 13 when sliding in the guide long hole. The limit plate 16 can move with the inner wall of the central hole of the sleeve when moving.

[0039] After the limiting plate 16 limits the position of the sleeve from the center hole of the sleeve, the pressure plate 9 is lifted to disconnect the pressure plate 9 from the sleeve, and the fixing sleeve 10 is connected to the rotating shaft 8 using a locking bolt, and the telescopic rod 18 stops running, and the two sealing doors 4 are pressurized so that the sealing doors 4 can seal the opening of the sealing cover 3;

[0040] The processing components can process the sleeve, and the debris generated during the processing of the sleeve is intercepted by the sealing cover 3 and the sealing door 4. When the processing direction needs to be changed, the handrail is pulled to drive the rack 21 to slide on the guide rod 20. When the rack 21 moves, it drives the rotating shaft 8 to rotate through the meshing gear 19. The rotating shaft 8 drives the sleeve 13, the limit plate 16, and the sleeve to rotate, so that the processing components can fully process the sleeve.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
