TECHNICAL FIELD

[0001] The utility model belongs to axle sleeve processing technical field, especially a clamping device for fan axle sleeve processing is provided. BACKGROUND

[0002] The axle sleeve is a cylindrical mechanical part that is sleeved on the rotating shaft and is a component part of the sliding bearing. Generally, the axle sleeve is in interference fit with the bearing seat and in clearance fit with the shaft. The axle sleeve is used to reduce the friction force suffered by the rotating shaft during rotation, which can reduce energy loss on the one hand and effectively avoid overheating of mechanical parts on the other hand.

[0003] In order to facilitate the installation of the axle sleeve, an installation hole needs to be formed on the workpiece during the processing of the axle sleeve. Before punching, the axle sleeve needs to be stabilized and punched without error through the clamping structure. Patent CN202223391578.3 discloses an automatic clamping device for axle sleeve processing, which comprises a base. By setting the limiting assembly, the axle sleeve to be clamped can be first limited during use, which facilitates subsequent clamping processing. By setting the clamping assembly, when the axle sleeve is placed on the limiting assembly during use, the clamping assembly will automatically clamp the axle sleeve, so that the axle sleeve cannot move to facilitate subsequent processing. By setting the reinforcing mechanism, the reinforcing mechanism can reinforce the axle sleeve clamped on the clamping assembly during use, so that the axle sleeve is completely fixed, which facilitates subsequent processing operation. By setting the pushing assembly, the pushing assembly can more conveniently open and close the limiting position of the limiting assembly, which facilitates use. The technical solution in the above-mentioned patent can only clamp the axle sleeve of a fixed size, and cannot meet the clamping and processing needs of axle sleeves of different specifications.

[0034] The present disclosure will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0035] As shown in Figures 1-4 A clamping device for processing a fan shaft sleeve includes a base 1, a support plate 2, a baffle 3, a support sleeve 4, and a fixing mechanism. The support plate 2 is fixed vertically on the base 1. The baffle 3 is fixed on the support plate 2. The support sleeve 4 is fixed on the baffle 3 and can accommodate the shaft sleeve 8. The fixing mechanism is used to fix the shaft sleeve and prevent the shaft sleeve from moving relative to the support sleeve 4.

[0036] Specifically, the fixing mechanism includes a top rod 51, a top plate 52, a connecting assembly, and a control assembly. The top rod 51 is uniformly arranged around the support sleeve 4. The support sleeve 4 is provided with a circular hole through which the top rod 51 passes. The top rod 51 can slide relative to the support sleeve 4. The top plate 52 is fixed on the end of the top rod 51 through the connecting assembly. The control assembly can drive the top plate 52 to move away from or close to the support sleeve 4. When fixing the shaft sleeve, the shaft sleeve is first sleeved on the support sleeve 4, and the end of the shaft sleeve is abutted against the baffle 3. Then, the control assembly drives the top rod 51 to move towards the support sleeve 4, so that the top plate 52 is abutted against the inner wall of the shaft sleeve hole, thereby completing the fixation of the shaft sleeve. By changing the moving distance of the top plate 52, the fixation of shaft sleeves of different specifications can be met, improving the versatility and applicability of the device.

[0037] As a preferred solution, the control assembly comprises a control rod 531, a push block 532, a limiting plate 533, a first elastic member 534 and an electric push rod 535. The control rod 531 is arranged through the baffle 3 and can slide relative to the baffle 3, and the axis of the control rod 531 coincides with the axis of the supporting sleeve 4. The push block 532 is fixed on the control rod 531 and is in the shape of a circular truncated cone. The end of the top rod 51 is in contact with the push block 532. The limiting plate 533 is fixed on the outer wall of the top rod 51. The first elastic member 534 is a spring which is sleeved on the top rod 51. One end of the first elastic member 534 is fixed on the limiting plate 533, and the other end is fixed on the inner wall of the supporting sleeve 4. The arrangement of the first elastic member 534 enables the top rod 51 and the top plate 52 to be automatically reset after machining, thereby improving the convenience and efficiency of operation. The electric push rod 535 is fixed on the base 1 through a fixed plate 536. The control rod 531 is moved by the electric push rod 535, which drives the push block 532 to move. The push block 532 is pressed during the movement, which drives the top plate 52 to move away from the supporting sleeve 4, thereby completing the fixation of the shaft sleeve. After machining, the control rod 531 is moved in the opposite direction, and the first elastic member 534 drives the top rod 51 and the top plate 52 to reset, so that the shaft sleeve can be removed.

[0038] As a preferred solution, the control assembly comprises a control rod 531, a push block 532, a limiting plate 533, a first elastic member 534 and an electric push rod 535. The control rod 531 is arranged through the baffle 3 and can slide relative to the baffle 3, and the axis of the control rod 531 coincides with the axis of the supporting sleeve 4. The push block 532 is fixed on the control rod 531 and is in the shape of a circular truncated cone. The end of the top rod 51 is in contact with the push block 532. The limiting plate 533 is fixed on the outer wall of the top rod 51. The first elastic member 534 is a spring which is sleeved on the top rod 51. One end of the first elastic member 534 is fixed on the limiting plate 533, and the other end is fixed on the inner wall of the supporting sleeve 4. The arrangement of the first elastic member 534 enables the top rod 51 and the top plate 52 to be automatically reset after machining, thereby improving the convenience and efficiency of operation. The electric push rod 535 is fixed on the base 1 through a fixed plate 536. The control rod 531 is moved by the electric push rod 535, which drives the push block 532 to move. The push block 532 is pressed during the movement, which drives the top plate 52 to move away from the supporting sleeve 4, thereby completing the fixation of the shaft sleeve. After machining, the control rod 531 is moved in the opposite direction, and the first elastic member 534 drives the top rod 51 and the top plate 52 to reset, so that the shaft sleeve can be removed.

[0039] In other embodiments, the end of the top rod 51 is rotatably provided with a ball 537, which is in contact with the push block 532. This reduces the friction between the top rod 51 and the push block 532, making the sliding of the top rod 51 smoother, reducing wear and prolonging the service life of the device.

[0040] In other embodiments, the top plate 52 is fixed with a rubber plate 521, which further enhances the stability of clamping and protects the surface of the shaft sleeve from being scratched due to the elasticity of the rubber plate 521.

[0042] In other embodiments, the control assembly further comprises a push plate 61, a connecting rod 62, an adjusting plate 63, a connecting plate 64, a mounting plate 65, a lead screw 66 and a guide rod 67. The push plate 61 is provided with a sliding groove and is fixed on the output end of the electric push rod 535. The connecting rod 62 is fixed on the outer wall of the control rod 531 and can slide relative to the sliding groove. The adjusting plate 63 is arranged in the sliding groove and can slide relative to the sliding groove. The mounting plate 65 is symmetrically fixed on both sides of the adjusting plate 63. The mounting plate 65 is fixed on the push plate 61. The lead screw 66 is rotatably connected to the mounting plate 65, and the connecting plate 64 is provided with a threaded hole matched with the lead screw 66. The guide rod 67 is fixed at one end on the mounting plate 65 and at the other end passes through the connecting plate 64. The connecting plate 64 can slide relative to the guide rod 67. The lead screw-guide rod linkage mechanism realizes micron-level control of the displacement of the push plate 61, and accurately converts the stroke of the electric push rod 535 into the clamping distance of the top plate 52 through the threaded pair transmission. The adjusting plate 63 cooperates with the sliding groove to support manual calibration, meeting the customized clamping needs of special specifications of shaft sleeves.

[0043] In other embodiments, the support sleeve 4 is sleeved with a guide sleeve 7, which facilitates sleeving the shaft sleeve on the support sleeve.
