[0002] The cage is a component of the bearing. In low-noise bearings, due to the requirement of quietness, the quality of the burr on the cage window is very high. At the same time, all parts in contact with the rolling elements must be chamfered, otherwise the quietness requirement cannot be guaranteed.

[0003] The process route of cage processing is to extrude and form first (complete the inner cavity size), then turn the outer diameter and outer groove to form the cage window hole. After processing, the upper part of the window hole is sharp-edged, rough and has burrs, and it cannot meet the quiet requirements after assembly. In the bearing industry, there is a lack of processing technology for chamfering and deburring the cage window hole. Manual files have been used to scrape and deburr the corners during the production process.

[0004] Manual deburring and chamfering have low efficiency, high labor costs, and unstable quality. Different people who do manual deburring will make different products, and the quality of the product is entirely determined by the person's sense of responsibility. Problems such as partial unscratching or unevenness often occur. Summary of the invention

[0025] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments:

[0026] like Figures 1 to 5 As shown, a chamfering and deburring device for a retainer window hole comprises: a grinding system, comprising a positioning plate 31, the positioning plate 31 is fixedly mounted on a frame 6, the retainer 4 is sleeved on the positioning plate 31, a circle of grinding wheel mechanisms 32 are arranged on the outer periphery of the positioning plate 31, the number of the grinding wheel mechanisms 32 is the same as the number of the window holes of the retainer 4, the grinding wheel mechanism 32 comprises a grinding wheel bracket 321 fixedly mounted on the frame 6, a grinding wheel connecting rod 322 is movably penetrated in the grinding wheel bracket 321, a grinding wheel 323 is arranged at the front end of the grinding wheel connecting rod 322, a driven wheel 324 is connected to the upper part of the grinding wheel 323, and a driven wheel 324 is connected to the other end of the grinding wheel connecting rod 322. A grinding wheel cylinder 325 is connected, and the grinding wheel cylinder 325 drives the grinding wheel 323 to enter or leave the window hole of the retainer 4. A spindle mechanism is arranged above the grinding wheel mechanism 32, and a driving wheel 331 is arranged at the bottom of the spindle mechanism. The driving wheel 331 is connected to the driver 332. The spindle mechanism is provided with a lifting system, and the lifting system drives the spindle mechanism to rise and fall. When the spindle mechanism falls to the lowest position, the driving wheel 331 is meshed with a driven wheel 324 of a circle of the grinding wheel mechanism 32 at the same time to drive the grinding wheel 323 to rotate. When the spindle mechanism rises to the highest position, the driving wheel 321 is separated from the driven wheel 324.

[0027] Feeding system, placing the retainer 4 on the positioning plate 31;

[0028] The material taking system takes the retaining frame 4 away from the positioning plate 31.

[0029] After the feeding system places the retaining frame 4 into the positioning plate 31, the lifting system drives the spindle mechanism to descend, the driver 332 is started, driving the driving wheel 331 to rotate, and the grinding wheel cylinder 325 drives the grinding wheel 323 to enter the window hole of the retaining frame 4. During the entry process, the driven wheel 324 engages with the driving wheel 331, driving the grinding wheel 323 to rotate. When the grinding wheel 323 enters the window of the retaining frame 4, it is in a rotating state, and the sharp corners and burrs of the window hole of the retaining frame 4 are evenly removed.

[0030] The device uses a driving wheel 331 to simultaneously drive a circle of grinding wheels 323 of the grinding wheel mechanism 32 to grind all the window holes of the retainer 4. Compared with manual deburring and chamfering, the device has the advantages of high efficiency and stable quality.

[0031] The grinding wheel 323 is preferably a diamond grinding wheel, which is suitable for grinding various metal parts.

[0032] During the grinding process, the driving wheel 331 can also adopt a forward and reverse driving process to drive the grinding wheel 323 to rotate forward and reverse in the window hole of the retaining frame 4 to ensure the processing accuracy.

[0033] The movable connection between the grinding wheel connecting rod 322 and the grinding wheel bracket 321 can adopt the following structure: the grinding wheel bracket 321 is provided with a square hole, and the grinding wheel connecting rod 322 is movably inserted into the square hole. Figure 3 shown.

[0034] In a preferred embodiment, the feeding system includes a first manipulator 21, and the first manipulator 21 includes a grasping mechanism 213, which grasps / releases the retaining frame 4; the moving mechanism includes horizontal movement, which moves the first manipulator 213 from the raw material warehouse to the positioning plate 31, and also includes vertical movement, which allows the first manipulator 21 to descend at the positioning plate 31 to release the retaining frame 4 and lift it up.

[0035] The first manipulator 21 grabs the retainer 4 at the raw material bin, moves horizontally to above the positioning plate 31, and then moves vertically downward to the positioning plate 31, sleeves the retainer 4 on the positioning plate 31, and releases the retainer 4. The first manipulator 21 moves in the vertical direction to avoid a circle of grinding wheel mechanisms 32 on the outer periphery of the positioning plate 31.

[0036] The horizontal movement of the first manipulator 21 can be achieved by rotation, such as Figure 2 As shown, specific institutions can take Figure 5 The special zone mechanism 213 is arranged on the horizontal moving rod 211, and the horizontal moving rod rotates relative to the vertical moving rod 212. The vertical moving rod 212 can be raised and lowered relative to the frame 6 to realize the vertical movement of the first manipulator 21.

[0037] The horizontal moving rod 211, the vertical moving rod 212 and the grabbing mechanism 213 can all be driven by cylinders.

[0038] The grasping mechanism 213 is preferably a three-claw mechanism, which grasps from the outer periphery of the retaining frame 4. The three-claw mechanism has a simple structure and can also ensure stable grasping of the circular retaining frame 4. The three-claw mechanism is grasped when it is contracted and released when it is opened.

[0039] A preferred structure of the raw material bin is, including a material rod 11, the outer periphery of which is provided with a positioning groove which cooperates with the window beam of the retaining frame 4, a plurality of retaining frames 4 are stacked and sleeved on the material rod 11, the raw material bin also includes a supporting tray 12 which supports the retaining frames 4, the supporting tray 12 is provided with a driving mechanism, the driving mechanism causes the supporting tray 12 to rise to the height of one retaining frame 4 each time or to descend to the bottom, and the top retaining frame 4 of the stacked retaining frames 4 is exposed from the material rod 11.

[0040] The positioning grooves on the periphery of the material rod 11 cooperate with the window beam of the retainer 4 to realize the circumferential positioning of the retainer 4, which is more convenient for the grasping mechanism 213 to grasp accurately. The first manipulator 21 puts the retainer 4 into the positioning plate 31 and can also accurately align the window hole with the grinding wheel 323. After the first manipulator 21 grasps a retainer 4, the material tray 12 rises to the height of a retainer 4 for the next grasping of the first manipulator 21. After the retainers 4 are taken out, that is, the material tray 12 rises to the set height, the material tray 12 drops to the lowest position, and then the retainers 4 are added to the material rod 11.

[0041] The driving mechanism of the support tray 12 can adopt a servo motor, and a ball screw linear guide pair is provided as a transmission mechanism.

[0042] One of the top retainers 4 of the stacked retainers 4 can be partially exposed from the material rod 11, and the first manipulator 21 descends to grab the retainer 4 and lifts it. The retainer 4 can also be completely exposed from the material rod 11. In this case, the first manipulator 21 does not need to descend when grabbing, but the retainer 4 may have a slight circumferential deviation.

[0043] A preferred structure of the material taking system includes a second manipulator 22. The structure of the second manipulator 22 is the same as that of the first manipulator 21, and only the installation position is different. The second manipulator 22 moves between the positioning plate 31 and the finished product bin, removes the processed retaining frame 4 from the positioning plate 31, and then puts it into the finished product bin. The second manipulator 22 descends at the positioning plate 31, grabs the retaining frame 4, and then moves to the finished product bin after lifting, and releases the retaining frame 4.

[0044] A preferred structure of the finished product silo includes a material box 7 and a material trough 71 . The second manipulator 22 moves to the material trough 71 to release the retaining frame 4 , and the retaining frame 4 slides from the material trough 71 into the material box 7 .

[0045] The material taking system does not need to ensure the circumferential position of the finished product retainer 4, so it can be directly placed in the material box 7. The material trough 71 is provided so that the retainer 4 can slide into the material box 7 to avoid damage caused by direct fall of the retainer 4, while the slight collision caused by sliding will not damage the retainer 4.

[0046] In a preferred embodiment, a positioning groove is provided on the outer periphery of the positioning plate 31 to cooperate with the window beam of the retaining frame 4. When the retaining frame 4 is loaded into the positioning plate 31, the retaining frame 4 is positioned, which can reduce the requirements for the movement accuracy of the first manipulator 21; at the same time, the retaining frame 4 is positioned during the grinding process to prevent the retaining frame 4 from shaking during grinding.

[0047] A preferred structure of the lifting system includes a slider guide rail mechanism and a power component 335, a driver 332 is fixed on the slider 333, a guide rail 334 and a power component 335 are fixed on the frame 6, and the power component 335 drives the slider 333 to move up and down. The power component 335 can be a cylinder, an oil cylinder, etc., and the driver 332 can be a servo motor.

[0048] In the present device, the frame 6 plays a supporting role. The specific shape of the frame 6 can be designed according to the requirements of each mechanism, and the frame 6 is not limited to a single component.

[0049] In this device, the feeding system, the material taking system and the grinding system are all mechanical structures, and no manual adjustment is required during the operation. Therefore, automatic control can be achieved through electrical components such as sensors and PLCs to carry out fully automatic production. The only manual operation required is to add material to the material rod 11 and replace the material box 7 with an empty material box. In on-site production, there is little demand for manpower, and employees can operate other equipment at the same time, which can improve the efficiency of shift production.

[0050] It should be emphasized that the above are only preferred embodiments of the present invention and do not limit the present invention in any form. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
