[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention.

[0026] like Figure 1-4 As shown, a bearing end surface grinding device includes a grinding wheel 5 and further includes:

[0027] A base frame 1 is provided with a support plate 3, and a motor 2 is provided on the support plate 3;

[0028] The clamping unit 6 is provided at the output end of the motor 2 and includes a fixed plate 64, a housing 61, and a turntable 67 rotatably connected to the housing 61. The turntable 67 is provided with a sliding rod 62 in a circumferential array that cooperates with the fixed plate 64. The sliding rod 62 is provided with a support block 63 that supports the grinding wheel 5. The fixed plate 64 is clamped to the housing 61.

[0029] A driving wheel 65 that cooperates with the turntable 67 is provided in the housing 61 . The driving wheel 65 rotates so that the turntable 67 controls the slide bar 62 to slide relative to or toward each other on the fixed plate 64 .

[0030] Specifically, the end face of the bearing is often processed by rough grinding, fine grinding and then polishing with a grinding wheel 5. The materials of the grinding wheels 5 for rough grinding, fine grinding and polishing are different, so that the grinding wheel 5 needs to be disassembled and assembled after each grinding. By rotating the driving wheel 65, the turntable 67 located in the housing 61 rotates, and the slide rod 62 slides along the fixed plate 64 until the support block 63 contacts the grinding wheel 5 and clamps it. The grinding wheel 5 is then controlled to rotate by the motor 2 to grind the end face of the bearing. The model of the motor 2 is: MHMF042L1U2M2. The device can be installed on a machine tool to further improve the flatness of the grinding of the bearing end face.

[0031] As an embodiment further provided by the present invention, the fixed plate 64 is provided with a first slide groove 641, and the turntable 67 is provided with a second slide groove 671. The slide rod 62 slides in the first slide groove 641 and the second slide groove 671. The first slide groove 641 has a guiding effect, and the second slide groove 671 has a pushing effect, so that the slide rod 62 slides relative to or toward the first slide groove 641 under the push of the second slide groove 671, thereby increasing the clamping range of the support block 63 to adapt to grinding wheels 5 of different sizes.

[0032] As an embodiment further provided by the present invention, an extension block 621 is provided at one end of the slide rod 62. The extension block 621 is replaceable. By changing the length of the extension block 621 and installing it on the slide rod 62, the clamping range of the support block 63 can be adjusted.

[0033] As an embodiment further provided by the present invention, the turntable 67 is provided with toothed blocks 672 in a circular array, the driving wheel 65 is engaged with the toothed block 672, a square block 651 is provided at one end of the driving wheel 65, and a locking cover 66 engaged with the square block 651 is provided on the shell 61. By rotating the driving wheel 65, the turntable 67 located in the shell 61 can be rotated through the engagement of the toothed block 672, thereby driving the slide bar 62 to slide on the turntable 67 and the fixed plate 64 to clamp the grinding wheel 5, and then when the locking cover 66 is in contact with the square block 651, the turntable 67 is locked to fix the slide bar 62, that is, the grinding wheel 5 is fixedly supported.

[0034] As an embodiment further provided by the present invention, a protective cover 4 is provided on the support plate 3, and a cooling spray gun 44 is rotatably provided on the protective cover 4. The cooling spray gun 44 is provided with an adjustment rod 43 that cooperates with the protective cover 4. The swinging adjustment rod 43 can control the spray angle of the cooling spray gun 44 at the protective cover 4. One end of the cooling spray gun 44 is connected to an external pipe, and the coolant is drawn through the external pipe and then sprayed by the cooling spray gun 44 onto the friction part of the grinding wheel 5, thereby reducing the temperature and also reducing a small amount of debris from splashing.

[0035] As an embodiment further provided by the present invention, the protective cover 4 is provided with a raised block 41 that engages with the support plate 3, and an opening 42 is opened on the protective cover 4. The raised block 41 is provided with an arc-shaped portion, which better engages with the support plate 3 through the arc-shaped portion, making it easier to install or disassemble the protective cover 4 and the support plate 3. The opening 42 is further set to prevent grinding debris from accumulating in the protective cover 4.

[0036] As an embodiment further provided by the present invention, a support groove 12 is provided in the base frame 1, and a slider 11 cooperating with the support plate 3 is slidably provided in the support groove 12. A screw 13 is rotatably connected to the base frame 1, and the screw 13 is threadedly connected to the slider 11. A knob is provided at one end of the screw 13, and the screw 13 on the base frame 1 can be rotated by turning the knob to make the slider 11 on the base frame 1 slide upward or downward in the vertical direction, thereby adjusting the height of the grinding wheel 5 and improving the adaptability of the device in different occasions.

[0037] Working principle: When the grinding wheel 5 is severely worn or needs to be replaced with another type of grinding wheel 5, the locking cover 66 is separated from the driving wheel 65 by hand, and the driving wheel 65 is rotated on the shell 61 through the square block 651, thereby driving the turntable 67 to rotate, and the slide rod 62 slides along the first slide groove 641 and the second slide groove 671, and then the spacing between each support block 63 is adjusted to adapt to pulleys of different specifications, and fixed to the clamping unit 6, and the protective cover 4 is clamped to the support plate 3 for safety protection to reduce the phenomenon of debris splashing during grinding.

[0038] The technical solution of the above-mentioned utility model provides a solution that is significantly different from the existing technology to address the technical problem that the existing technology solution is too single. The parts not involved in the technical solution of this application are the same as the existing technology or can be implemented by using the existing technology, and will not be repeated here.

[0039] The technical solutions in the above embodiments have clearly and completely described the contents of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.
