Description

Technical Field

[0001] The utility model relates to the technical field of inner hole cleaning, in particular to an inner hole cleaning device for machining a bearing retainer. Background Art

[0002] The inner hole cleaning device is a device for cleaning and trimming the inner hole of a workpiece with an inner hole. For example, the cleaning of the inner hole of a bearing retainer and a turbine shaft requires the use of an inner hole cleaning device.

[0003] In the prior art, a utility model patent with authorization announcement number CN219664513U discloses a turbine shaft inner hole cleaning device. In this patent, the turbine shaft is self-centering and clamped in position by a three-jaw chuck, and then the positioned turbine shaft inner hole is cleaned in conjunction with a cleaning mechanism. Since the bearing retainer and the turbine shaft are both hollow cylinders, the same inner hole cleaning device can be used to perform the inner hole cleaning operation.

[0004] When using the above-mentioned inner hole cleaning device to clean the inner hole of the bearing retainer, it was found that the three-jaw chuck uses three jaws to move synchronously toward or in the opposite direction. When the bearing retainer is self-centering and clamped and positioned, it only relies on the radial clamping force of the bearing retainer to clamp and position. Since the bearing retainer is a hollow annular structure, excessive radial clamping force of the three jaws may cause deformation and damage of the bearing retainer, while if the radial clamping force is too small, when the cleaning mechanism contacts the inner hole of the bearing retainer for cleaning, due to the vibration and friction resistance caused by its operation, the bearing retainer may be laterally offset or tilted, affecting the quality of cleaning the inner hole of the bearing retainer. For this reason, an inner hole cleaning device for bearing retainer processing is proposed. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides Figure 1-4The inner hole cleaning device for machining a bearing retainer shown in the figure comprises a three-jaw chuck 100 and a cleaning mechanism. The three-jaw chuck 100 can realize three-axis positioning. One side of the three-jaw chuck 100 also has a driving device to drive the three-jaw chuck 100 to rotate, so that the bearing retainer positioned by the three-jaw chuck 100 can be driven to rotate, so as to facilitate the subsequent cleaning of various parts of the inner hole of the bearing retainer. The cleaning mechanism comprises a linear servo module 1 200, a linear servo module 2 300 and a cleaning assembly. The linear servo module 1 200 is used to adjust the lateral position of the linear servo module 2 300, and the linear servo module 2 300 is used to adjust the longitudinal position of the cleaning component. After the bearing holder is positioned by the three-jaw chuck 100, the inner wall of the inner hole of the bearing holder can be cleaned by the cleaning mechanism; the cleaning component includes a motor seat 402 fixed to the moving end on the linear servo module 2 300, and the top of the motor seat 402 is fixedly connected to a driving motor 401, and the rotating end of the driving motor 401 is transmission-connected to a grinding roller 400. The linear servo module 1 200 drives the linear servo module 2 300 to move horizontally, and the lateral position of the cleaning component is adjusted so that the grinding roller 400 in the cleaning component can extend into To the positioned inner hole of the bearing holder, and then the linear servo module 2 300 drives the motor seat 402 to move horizontally in the longitudinal direction, so that the grinding roller 400 can contact the inner wall of the inner hole of the bearing holder, and finally the grinding roller 400 is driven by the driving motor 401 to rotate to clean the inner hole of the bearing holder; in a preferred embodiment, the linear servo module 1 200 and the linear servo module 2 300 both include a shell 201, a rotatable one-way screw 202 is provided in the shell 201, and one end of the one-way screw 202 extends to the outside of the shell 201 and is fixedly connected to a turntable 204, the outer wall of the one-way screw 202 is threadedly connected with a nut seat 203, the top of the nut seat 203 extends to the top of the shell 201, and the top of the shell 201 is provided with a linear through groove for guiding the movement of the nut seat 203. The driving method of the linear servo module 1 200 and the linear servo module 2 300 is to manually drive the one-way screw 202 to rotate clockwise or counterclockwise through the turntable 204, and drive the nut seat 203 to move along the one-way screw 202, so as to drive the linear servo module 2 300 or the motor seat 402 connected thereto to move horizontally, so as to adjust the position of the grinding roller 400.
