[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. According to the different friction properties of moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Bearing surface treatment devices are required in the process of bearing processing, and grinding is one of the processes for bearing surface treatment.

[0003] For example, the specification of patent publication CN117107041B discloses a wheel hub bearing surface treatment device, which includes a workbench, the top front end of the workbench is fixedly connected to an induction heater, the top of the workbench is fixedly connected to a protective cover, the top of the protective cover is fixedly connected to a slide rail, the bottom of the slide rail is slidably connected to a slider, the bottom of the slider is fixedly connected to a first electric push rod, the bottom of the first electric push rod is fixedly connected to a clamp, the front end of the clamp penetrates and is fixedly connected to a third electric push rod, and the rear end of the third electric push rod is fixedly connected to a motor. By setting a second electric push rod on the left and right sides of the rear end of the protective cover, a servo motor is fixedly connected to the output end of the second electric push rod, and the output end of the servo motor is fixedly connected to a connecting rod and a grinding wheel, the two surfaces of the bearing can be polished at the same time.

[0004] Based on the above search and in combination with the prior art, it is found that during the grinding process, the existing bearing processing surface treatment device needs to gradually feed the grinding disc or workpiece through an additional feed drive device to ensure stable grinding operation, and the operation energy consumption is relatively high. Therefore, a surface treatment mechanism for bearing processing is proposed to improve the above problems. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that during the grinding process, the existing bearing surface treatment device needs to gradually feed the grinding disc or workpiece through an additional feeding drive device to ensure stable grinding operation, and the operating energy consumption is relatively high.

[0006] In order to solve the above problems, the present invention provides a surface treatment mechanism for bearing processing, comprising:

[0007] frame;

[0008] A fixing mechanism, the fixing mechanism is installed on one side of the inner part of the frame, and a bearing member is fixed on the inner side of the fixing mechanism;

[0009] A grinding mechanism is installed on the other side of the frame. The grinding mechanism includes a second drive motor and a feeding part. The second drive motor is installed on the side end of the frame. A grinding disc is installed on the output end of the second drive motor through the feeding part. The feeding part is deformed by accelerating the rotation speed of the second drive motor, so that the grinding disc maintains a stable friction force with the bearing member fixed on the inner side of the fixing mechanism.

[0010] The transmission mechanism is installed at the inner bottom end of the frame, and the transmission mechanism is installed between the fixing mechanism and the grinding mechanism. When the driving motor 2 drives the grinding disc to rotate, the bearing part fixed on the inner side of the fixing mechanism is driven to rotate through the transmission mechanism to achieve the grinding effect on the bearing part.

[0011] In the above-mentioned surface treatment mechanism for bearing processing, the rotation speed of the driving motor 2 is accelerated to cause the feed part to deform, so that the grinding disc maintains a stable friction force with the bearing part fixed on the inner side of the fixing mechanism, without the need for additional feeding driving equipment, thereby effectively reducing the operating energy consumption; through the setting of the transmission mechanism, when the driving motor 2 drives the grinding disc to rotate, the bearing part fixed on the inner side of the fixing mechanism is driven to rotate through the transmission mechanism to achieve the grinding effect on the bearing part, and the grinding disc and the bearing part are driven by a driving motor 2, further reducing the operating energy consumption.

[0012] As a further supplement to the present application, the feeding portion includes a feeding assembly, a baffle and a telescopic structure;

[0013] The grinding disc is coaxially connected with the output shaft of the second driving motor through a telescopic structure, and the feeding assembly and the baffle are both installed on the telescopic structure.

[0014] As a further supplement to the present application, the telescopic structure includes a transmission shaft, a limiting square rod and an elastic reset member 2;

[0015] The transmission shaft is coaxially fixed with the output shaft of the second driving motor, and a limiting square hole slidably sleeved with the limiting square rod is provided at the end of the transmission shaft away from the second driving motor, and the second elastic reset member is fixed between the limiting square rod and the inner wall of the limiting square hole;

[0016] The feeding assembly is installed on the limiting square rod, the baffle is fixed on the transmission shaft, and the fixing mechanism is connected with the transmission shaft through the transmission mechanism.

[0017] As a further supplement to the present application, the feed assembly includes a sliding sleeve, a sliding column and an elastic reset member;

[0018] The sliding sleeve is fixed to the side end of the limiting square rod, and the sliding sleeve is inclined toward one side of the baffle plate. The sliding column is slidably sleeved on the inner side of the sliding sleeve, and one end of the sliding column close to the baffle plate extends to the outer side of the sliding sleeve. The sliding column is fixed to the inner side of the sliding sleeve through an elastic reset member.

[0019] By increasing the speed of driving motor 2 to increase the centrifugal force on the sliding column, it slides outward along the length direction of the sliding sleeve and squeezes the baffle at the same time. Since the baffle is fixed on the transmission shaft, it cannot move in the horizontal direction. At this time, the limiting square rod moves the grinding disc toward one side of the bearing under the reverse force, thereby realizing the automatic feeding of the grinding disc without the need for additional feeding drive equipment, thereby effectively reducing operating energy consumption.

[0020] As a further supplement to the present application, a roller is installed at the end of the sliding column located outside the sliding sleeve; the provided roller can reduce the friction between the sliding column and the baffle.

[0021] As a further supplement to the present application, the fixing mechanism includes a driving motor 1, a bidirectional threaded rod, a guide slide rod, two slide blocks and two fixing plates;

[0022] The driving motor 1 is fixed on the frame, the bidirectional threaded rod and the guide slide rod are both vertically installed on the inner side of the frame, one end of the bidirectional threaded rod is coaxially fixed with the output shaft of the driving motor 1, the other end of the bidirectional threaded rod is rotatably connected with the frame and threadedly penetrates the slide bar, the two slide bars are symmetrically connected to the bidirectional threaded rod, and the guide slide bar slides through the slide bar;

[0023] A connecting frame is installed on the side end of the slider close to the grinding mechanism, and two fixing plates are respectively installed on the ends of the two connecting frames away from the slider;

[0024] The fixing plate located at the lower side is connected with the transmission shaft through a transmission mechanism.

[0025] As a further supplement to the present application, the transmission mechanism includes a first bevel gear, a second bevel gear and a transmission group;

[0026] The first bevel gear is coaxially fixed with the transmission shaft, a support cover is installed at the inner bottom end of the frame, the second bevel gear is vertically installed on the support cover and meshes with the first bevel gear, and the second bevel gear is connected to the fixed plate through a transmission group.

[0027] As a further supplement to the present application, the transmission group includes a transmission pulley and a transmission belt, two transmission pulleys are provided, and the transmission belt is connected between the two transmission pulleys;

[0028] One of the transmission pulleys is coaxially fixed with the second bevel gear, and the other transmission pulley is rotatably installed on the support cover and is coaxially arranged with the fixed plate. A limiting square column is coaxially fixed to the bottom end of the fixed plate located on the lower side. The limiting square column slides vertically through the transmission pulley and is rotatably connected with the connecting frame. When the driving motor 2 drives the grinding plate to rotate, the limiting square column is driven to rotate through the first bevel gear, the second bevel gear and the transmission group. The limiting square column then drives the bearing part to rotate through the fixed plate, and cooperates with the rotating grinding plate to realize the grinding effect on the bearing part. The grinding plate and the bearing part are driven by a driving motor 2, which further reduces the operating energy consumption.

[0029] As a further supplement to the present application, a pressure sensor is installed between the limiting square rod and the grinding disc.

[0030] In summary, by increasing the rotation speed of the second driving motor so that the centrifugal force on the sliding column becomes larger, it slides outward along the length direction of the sliding sleeve and squeezes the baffle at the same time. Since the baffle is fixed on the transmission shaft, it cannot move in the horizontal direction. At this time, the limiting square rod moves with the grinding disc toward one side of the bearing part under the reverse force, thereby realizing the automatic feeding of the grinding disc without the need for additional feeding drive equipment, thereby effectively reducing the operating energy consumption; when the second driving motor drives the grinding disc to rotate, the limiting square column is driven to rotate through the first bevel gear, the second bevel gear and the transmission group, and the limiting square column rotates with the bearing part through the fixed disc, and the rotating grinding disc realizes the grinding of the bearing part. The grinding disc and the bearing part are driven by a second driving motor, which further reduces the operating energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] An implementation method of the present application is described in detail below with reference to the accompanying drawings.

[0042] The first implementation method:

[0043] The present invention provides a surface treatment mechanism for bearing processing, see Figure 1-8 , including a frame 1, a fixing mechanism 2, a grinding mechanism 3 and a transmission mechanism 5.

[0044] The fixing mechanism 2 is installed on one side of the inner part of the frame 1, and a bearing is fixed on the inner side of the fixing mechanism 2. Specifically, Figure 2 As shown, the fixing mechanism 2 includes a driving motor 21, a bidirectional threaded rod 22, a guide slide bar 23, two sliders 24 and two fixed plates 27. The driving motor 21 is fixed on the frame 1. The bidirectional threaded rod 22 and the guide slide bar 23 are both vertically installed on the inner side of the frame 1. One end of the bidirectional threaded rod 22 is coaxially fixed to the output shaft of the driving motor 21, and the other end of the bidirectional threaded rod 22 is rotatably connected to the frame 1 and threadedly penetrates the slider 24. The two sliders 24 are symmetrically connected to the bidirectional threaded rod 22. The guide slide bar 23 slides through the slider 24. A connecting frame 25 is installed on the side end of the slider 24 close to the grinding mechanism 3, and two fixed plates 27 are respectively installed on the ends of the two connecting frames 25 away from the slider 24.

[0045] The grinding mechanism 3 is installed on the other side of the frame 1. Specifically, Figure 4As shown, the grinding mechanism 3 includes a driving motor 31 and a feeding part. The driving motor 31 is installed at the side end of the frame 1. The output end of the driving motor 31 is installed with a grinding disc 4 through the feeding part. The feeding part is deformed by accelerating the rotation speed of the driving motor 31, so that the grinding disc 4 maintains a stable friction force with the bearing part fixed on the inner side of the fixing mechanism 2.

[0046] Specifically, the feeding part includes a feeding assembly 33, a baffle 34 and a telescopic structure. The grinding disc 4 is coaxially connected to the output shaft of the second driving motor 31 through the telescopic structure. The feeding assembly 33 and the baffle 34 are both installed on the telescopic structure; the telescopic structure includes a transmission shaft 32, a limiting square rod 35 and an elastic reset member 36. The transmission shaft 32 is coaxially fixed with the output shaft of the second driving motor 31. The end of the transmission shaft 32 away from the second driving motor 31 is provided with a limiting square hole 3201 slidably sleeved with the limiting square rod 35. The elastic reset member 36 is fixed between the limiting square rod 35 and the inner wall of the limiting square hole 3201. The feed assembly 33 is installed on the limiting square rod 35, the baffle 34 is fixed on the transmission shaft 32, and the fixed disk 27 located on the lower side is connected to the transmission shaft 32 through the transmission mechanism 5. The feed assembly 33 includes a sliding sleeve 331, a sliding column 332 and an elastic return member 333. The sliding sleeve 331 is fixed to the side end of the limiting square rod 35, and the sliding sleeve 331 is inclined toward one side of the baffle 34. The sliding column 332 is slidably sleeved on the inner side of the sliding sleeve 331, and one end of the sliding column 332 close to the baffle 34 extends to the outer side of the sliding sleeve 331, and the sliding column 332 is fixed to the inner side of the sliding sleeve 331 through an elastic return member 333.

[0047] Based on the coordinated arrangement of the above structure, the rotation speed of the driving motor 2 31 is increased to increase the centrifugal force on the sliding column 332, so that it slides outward along the length direction of the sliding sleeve 331, and at the same time squeezes the baffle 34. Since the baffle 34 is fixed on the transmission shaft 32, it cannot move in the horizontal direction. At this time, the limiting square rod 35 moves the grinding disc 4 toward one side of the bearing part under the reverse force, thereby realizing the automatic feeding of the grinding disc 4 without the need for additional feeding drive equipment, thereby effectively reducing the operating energy consumption.

[0048] In addition, by installing a pressure sensor (not shown in the figure) between the limiting square rod 35 and the grinding disc 4, the pressure sensor and the drive motor 2 31 are electrically connected to the external controller, and the pressure sensor is used to detect the pressure exerted on the grinding disc 4 during the grinding process, so that the adaptive speed of the drive motor 2 31 is controlled by the external controller, which is more intelligent and reliable.

[0049] like Figure 6 As shown, a roller 334 is installed at the end of the sliding column 332 located outside the sliding sleeve 331 ; the roller 334 can reduce the friction between the sliding column 332 and the baffle 34 .

[0050] Among them, Figure 1 It is shown that the transmission mechanism 5 is installed at the inner bottom end of the frame 1, and the transmission mechanism 5 is installed between the fixing mechanism 2 and the grinding mechanism 3. When the driving motor 2 31 drives the grinding disc 4 to rotate, the bearing part fixed on the inner side of the fixing mechanism 2 is driven to rotate through the transmission mechanism 5 to achieve the grinding effect on the bearing part.

[0051] Specifically, the transmission mechanism 5 includes a first bevel gear 51, a second bevel gear 52 and a transmission group. The first bevel gear 51 is coaxially fixed with the transmission shaft 32. A support cover is installed at the inner bottom end of the frame 1. The second bevel gear 52 is vertically installed on the support cover and meshes with the first bevel gear 51. The second bevel gear 52 is connected to the fixed disk 27 through the transmission group. The transmission group includes a transmission pulley 53 and a transmission belt 54. Two transmission pulleys 53 are provided. The transmission belt 54 is transmission-connected between the two transmission pulleys 53. One of the transmission pulleys 53 is coaxially fixed with the second bevel gear 52, and the other transmission pulley 53 is rotatably installed on the support cover and is coaxially arranged with the fixed disk 27. The bottom end of the fixed disk 27 located on the lower side is coaxially fixed with a limited square column 26. The limited square column 26 vertically slides through the transmission pulley 53 and is rotationally connected with the connecting frame 25.

[0052] Based on the coordinated arrangement of the above structure, when the driving motor 2 31 drives the grinding disc 4 to rotate, the limiting square column 26 is driven to rotate through the first bevel gear 51, the second bevel gear 52 and the transmission group, and the limiting square column 26 rotates with the bearing part through the fixed plate 27, and cooperates with the rotating grinding disc 4 to realize the grinding effect on the bearing part. The grinding disc 4 and the bearing part are driven by a driving motor 2 31 together, which further reduces the operating energy consumption.

[0053] Working principle: The bearing is fixed in a fixed position by using the fixing mechanism 2, and the centrifugal force on the sliding column 332 is increased by increasing the speed of the driving motor 2 31, so that the sliding column 332 slides outward along the length direction of the sliding sleeve 331 (such as Figure 6 is the state before the sliding column 332 slides, Figure 7 The baffle plate 34 is squeezed at the same time. Since the baffle plate 34 is fixed on the transmission shaft 32, it cannot move in the horizontal direction. At this time, the limiting square rod 35 moves the grinding disc 4 toward one side of the bearing part under the reverse force, thereby realizing the automatic feeding of the grinding disc 4, without the need for additional feeding driving equipment, thereby effectively reducing the operating energy consumption; when the driving motor 2 31 drives the grinding disc 4 to rotate, the limiting square column 26 is driven to rotate through the first bevel gear 51, the second bevel gear 52 and the transmission group, and the limiting square column 26 rotates with the bearing part through the fixed plate 27, and the rotating grinding disc 4 realizes the grinding effect on the bearing part. The grinding disc 4 and the bearing part are driven by a driving motor 2 31, which further reduces the operating energy consumption.

[0054] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
