DETAILED DESCRIPTION

[0025] 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.

[0026] Example

[0027] This embodiment is intended to promote the solution of the problem that the grinding device in the prior art can only grind one side of the bearing, and the common solution usually consumes a large labor cost or economic cost. Figure 1-7 ,

[0028] A household appliance deep groove ball bearing cutting device comprises a base plate 1, on which a No. 1 mounting frame 2 and a No. 2 mounting frame 3 are mounted, a sliding device 4 is mounted on the No. 1 mounting frame 2, a working device 5 for grinding a bearing 7 and a rotating device 8 for driving the bearing 7 to rotate are mounted on the sliding device 4, a pneumatic clamping device 6 is mounted on the No. 2 mounting frame 3, the rotating device 8 comprises a driving rod 803 mounted on the sliding device 4, a No. 2 one-way spring 804 is mounted on the driving rod 803, the rotating device 8 further comprises a disc 801 mounted on the pneumatic clamping device 6, and a No. 1 one-way spring 802 is mounted on the side wall of the disc 801.

[0029] The sliding device 4 includes a screw motor 401 installed on the No. 1 mounting frame 2, the output end of the screw motor 401 is fixedly connected to a screw 402, a slide plate 403 is rotatably connected to the screw 402, the slide plate 403 is slidably connected in a guide plate 404, the guide plate 404 is fixedly connected to the base plate 1, the slide plate 403 is fixedly connected to a mounting plate 406 via a connecting rod 405, and the mounting plate 406 is installed with a working device 5 and a rotating device 8.

[0030] The rotating device 8 includes a disc 801 fixedly connected to the side wall of the T-shaped plate 607 , and a first one-way spring sheet 802 is fixedly connected to the side wall of the disc 801 .

[0031] The rotating device 8 further includes a driving rod 803 , which is fixedly connected to the mounting plate 406 , and a second one-way spring 804 is fixedly connected to one side of the driving rod 803 .

[0032] By driving the screw motor 401 and the screw rod 402, the slide plate 403 can slide under the restriction of the guide plate 404, so that the working device 5 on the slide plate 403 can grind the bearing 7. When the screw motor 401 drives the slide plate 403 to grind one side of the bearing 7, the driving rod 803 and the second one-way spring 804 on the mounting plate 406 will be inserted into the gap of the first one-way spring 802 on the disc 801, as shown in FIG. Figure 7 As shown, during this process, due to the one-way design of the one-way spring piece No. 1 802 and the one-way spring piece No. 2 804, the T-shaped plate 607 fixedly connected thereto will not be driven to rotate, which effectively avoids the situation in which the first grinding process fails due to the friction between the one-way spring piece No. 1 802 and the one-way spring piece No. 2 804 causing the T-shaped plate 607 to rotate.

[0033] After the grinding of one side is completed, the screw motor 401 drives the guide plate 404, the driving rod 803 and the second one-way spring 804 to retreat. During the process, the second one-way spring 804 on the driving rod 803 conflicts with the first one-way spring 802 on the disc 801, driving the T-plate 607 to rotate. The rotation of the T-plate 607 can realize the rotation of the bearing 7, and then the other side of the bearing 7 can be polished by driving the guide plate 404 forward again. This design can effectively realize the double-sided grinding of the bearing 7 through a grinding device, avoiding unnecessary labor and economic costs.

[0034] The pneumatic clamping device 6 includes a clamping base 601 fixedly connected to the No. 2 mounting frame 3, a driving chamber 602 is provided in the clamping base 601, an electric push rod 603 is installed in the driving chamber 602, an output end of the electric push rod 603 is fixedly connected to a piston plate 604, the piston plate 604 is slidably connected in the driving chamber 602, and the driving chamber 602 is connected to the piston chamber 606 through a channel 605.

[0035] A T-shaped plate 607 is slidably connected in the piston chamber 606 , a spring 608 is fixedly connected to one side of the T-shaped plate 607 , and a clamping block 609 is fixedly connected to one end of the T-shaped plate 607 .

[0036] The other end of the spring 608 is fixedly connected to a limited rotation plate 610 , and the limited rotation plate 610 is rotatably connected in the clamping base 601 .

[0037] The electric push rod 603 serves as the power source of the pneumatic clamping device 6 and provides power support for the clamping of the bearing 7. The electric push rod 603 drives the piston plate 604 to squeeze the gas in the driving chamber 602, and drives the air pressure to be transmitted to the piston chambers 606 on both sides through the channel 605, and then drives the clamping blocks 609 on both sides to move toward the middle at the same time through the sliding of the T-plate 607. This drive can effectively ensure that the central axis of the bearing 7 is fixed, and then effectively ensure that the center line of the grinding motor 501 in the working device 5 is colinear with the central axis of the bearing 7, effectively ensuring the accuracy of the grinding work of the working device 5 and the rotation work of the rotating device 8. The design of the spring 608 effectively ensures that the fixed bearing 7 can be smoothly disassembled after the grinding work is completed, and the design of the spring 608 being rotatably connected to the clamping base 601 through the limit rotating plate 610 can effectively ensure that the spring 608 will not be twisted under the rotation of the T-plate 607, resulting in damage to the spring 608, thereby ensuring the stability of the device operation.

[0038] The working device 5 includes a grinding motor 501 , which is fixedly connected to the slide plate 403 . The output end of the grinding motor 501 is fixedly connected to a rotating disk 502 , which is rotatably connected in the mounting plate 406 , and a grinding block 503 is fixedly connected to the rotating disk 502 .

[0039] The rotating disk 502 connected to the grinding motor 501 drives the grinding block 503 to grind the bearing 7. The rotating connection between the rotating disk 502 and the mounting plate 406 can effectively ensure the independence of the grinding work and the rotation work, and effectively prevent the working device 5 and the rotating device 8 from being linked, resulting in the failure of the grinding work.

[0040] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
