Description

Technical Field

[0001] The utility model relates to the technical field of shaft sleeve processing, in particular to an auxiliary clamping and fixing mechanism for shaft sleeve processing. Background Art

[0002] The sleeve is a cylindrical mechanical part that is sleeved on the rotating shaft and is a component of the sliding bearing. Generally speaking, the sleeve and the bearing seat adopt an interference fit, and the shaft adopts a clearance fit. During the production and processing of the sleeve, in order to make the sleeve parts meet the technical requirements such as the size, geometry and relative position accuracy with other surfaces specified in the drawings, it is necessary to use a lathe to process it. In order to prevent the sleeve from shifting during processing, the staff will use a clamping mechanism to limit and fix it.

[0003] The existing sleeve processing process usually only sets a clamping mechanism on one end of the sleeve, which is clamped by a hand-cranked screw without an auxiliary clamping structure. When the sleeve rotates, its position is prone to deviation.

[0004] Therefore, the problem of the lack of an auxiliary clamping mechanism in the above-mentioned sleeve processing link, which easily causes the sleeve position to deviate, urgently needs to be solved to improve the positioning process of the sleeve processing. Utility Model Content

[0005] In order to overcome the problem that the existing sleeve processing process usually only sets a clamping mechanism on one end of the sleeve, and clamps it by hand-cranked screw drive, and no auxiliary clamping structure is set, when the sleeve rotates, it is easily affected by high-speed rotation and equipment vibration, and its position is easily deviated.

[0006] The technical solution of the utility model is: an auxiliary clamping and fixing mechanism for shaft sleeve processing, including a fixing frame, a base is installed on the bottom surface of the fixing frame, an anti-slip pad is adhered to the bottom surface of the base, a driving assembly is arranged inside the vertical rods on both sides of the fixing frame, a fitting assembly is arranged below the driving assembly, a fixing assembly is installed on the upper surface of the horizontal rod of the fixing frame, and auxiliary components are arranged on the bottom of the fitting assembly and the top of the fixing assembly.

[0007] Preferably, by setting a driving component, the upper auxiliary component can be pressed down, thereby cooperating with the lower auxiliary component to complete the auxiliary clamping and positioning of the sleeve, thereby solving the problem that the existing equipment only clamps and positions one end of the sleeve when processing the sleeve, and no auxiliary clamping structure is set, which makes the position of the sleeve easily deviate during processing, resulting in a decrease in processing accuracy.

[0008] Preferably, the driving assembly includes a driving motor, a screw, a movable seat and a support plate; a driving motor is provided on the inner bottom surface of the right vertical rod of the fixed frame, a screw is installed on the output end of the driving motor, the outer surface of the screw is threadedly connected to the movable seat, and a support plate is installed on the left surface of the movable seat. The operation of the driving motor drives the screw to rotate, thereby driving the movable seat on its surface to move up and down, so that the connecting plate drives the upper auxiliary assembly to press down, thereby completing the auxiliary positioning of the sleeve.

[0009] Preferably, the driving assembly includes a slide and a slide rod; the left end of the support plate is welded with the slide, and the slide rod is arranged inside the left vertical rod of the fixed frame. The slide is slidably connected to the slide rod. By setting the slide rod, when the support plate moves downward, the slide welded to the left end of the support plate will slide on the surface of the slide rod, thereby improving the smoothness and accuracy of the descent.

[0010] Preferably, the fitting component includes a damper, a spring and a threaded connection seat; a damper is installed in the middle position of the bottom surface of the support plate, the outer sleeve of the damper is provided with a spring, and the bottom of the damper is connected to the threaded connection seat. By arranging the damper and the spring, after the shaft sleeve is clamped, the shaft sleeve will be driven to rotate by the motor. Due to slight deviations in concentricity, the shaft sleeve will float up and down during rotation. The cooperation between the damper and the spring can offset this part of the floating and reduce damage to the drive motor.

[0011] Preferably, the fixing assembly includes a fixing column, a fixing groove and a fixing block; a fixing column is installed on the upper surface of the cross bar of the fixing frame, a fixing groove is provided on the top of the fixing column, and a fixing block is engaged with the inside of the fixing groove. By providing a fixing groove on the top of the fixing column, the fixing block can be positioned, and the teeth on the surface of the fixing block will fit into the fixing groove, thereby limiting the rotation of the fixing block.

[0012] Preferably, the auxiliary component includes a clamping jaw; the upper surface of the fixed block and the bottom surface of the threaded connection seat are both provided with clamping jaws, and the clamping jaws are provided with multiple groups of different specifications. By using the fixed block and the threaded connection seat to install the clamping jaws, it is convenient for the staff to quickly replace the clamping jaws, thereby improving the applicability of the equipment.

[0013] Preferably, the auxiliary component includes a mounting groove and a rotating shaft; the clamping surface of the clamping jaw is provided with a mounting groove, and the internal rotation of the mounting groove is connected to several rotating shafts. By setting the rotating shaft, after the clamping jaw clamps the sleeve, the surface of the sleeve will fit with the rotating shaft. When the sleeve rotates, the rotating shaft will rotate synchronously, and the auxiliary sleeve will rotate.

[0014] Beneficial effects of the utility model:

[0015] 1. By setting a driving assembly, the upper auxiliary assembly can be pressed down, thereby cooperating with the lower auxiliary assembly to complete the auxiliary clamping and positioning of the sleeve. This solves the problem that the existing equipment only clamps and positions one end of the sleeve during sleeve processing, and no auxiliary clamping structure is set. The position of the sleeve is prone to deviation during processing, resulting in reduced processing accuracy.

[0016] 2. By setting the damper and the spring, after the sleeve is clamped, the sleeve will be driven to rotate by the motor. Due to slight deviation in concentricity, the sleeve will float up and down during rotation. The cooperation of the damper and the spring can offset this part of the floating and reduce damage to the drive motor. In addition, by setting the rotating shaft, after the clamping claws clamp the sleeve, the surface of the sleeve will fit with the rotating shaft. When the sleeve rotates, the rotating shaft will rotate synchronously to assist the sleeve in rotation. BRIEF DESCRIPTION OF THE DRAWINGS
