[0002] With the continuous development of industrial manufacturing technology, bearings, as an important mechanical component, are widely used in various machines and equipment. As an important part of the bearing, the surface quality of the bearing outer ring has a crucial impact on the performance and service life of the bearing. During the manufacturing process of the bearing outer ring, it is often necessary to polish and remove scars on the outer surface to ensure its smoothness and dimensional accuracy.

[0003] Currently, the operation of polishing and removing scars on the bearing outer ring is mainly achieved by a centerless grinding machine. A centerless grinding machine is a machine tool that grinds workpieces with a grinding wheel, and has advantages such as high automation and good machining accuracy. However, when the existing centerless grinding machine processes the bearing outer ring, both loading and unloading need to be manually coordinated, resulting in a low processing efficiency of the centerless grinding machine and unable to achieve batch and rapid production.

The lifting basket is inclined and the two inclined ends are open, and the lower end of the lifting basket faces the baffle plate.

[0011] In one embodiment: width-limiting plates for adjusting the channel width are provided on the feeding channel, the discharging channel, and the lifting basket.

[0012] In one embodiment: the conveying mechanism is a conveyor belt. The discharging end of the discharging channel is closed, and a flipping structure is provided below the discharging end.

Detailed implementation manners

[0025] The following further describes the present application in detail with reference to the accompanying drawings.

[0026] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present application.

[0027] A bearing outer ring scar-removing machine, as Figure 1 shown, includes a scar-removing mechanism 100, a feed channel 200 and a discharge channel 300 provided at both ends of the scar-removing mechanism 100, and a lifting mechanism 400 for feeding the outer ring of the bearing 610 out of the discharge channel 300.

[0028] As Figure 2As shown, the feeding channel 200 is inclined. Its higher end is the loading end and its lower end is the discharging end. Among them, a docking mechanism 500 is provided at the loading end. The docking mechanism 500 includes a baffle 510 located below the feeding channel 200, a lifting cylinder 520 installed at the bottom of the baffle 510, and a lifting basket 530 installed on the lifting cylinder 520. The lifting basket 530 is inclined and both ends of the inclination are open. The lower end of the lifting basket 530 faces the baffle 510, and the higher end is for the outer ring workpiece of the bearing 610 to be fed into the lifting basket 530. Through the docking mechanism 500, the feeding channel 200 can be docked with the previous process of the outer ring workpiece of the bearing 610 without considering the height of the loading end of the feeding channel 200. When the lifting height of the lifting basket 530 is higher than the baffle 510, the outer ring workpiece of the bearing 610 rolls into the feeding channel 200 through the bottom of the inclined lifting basket 530.

[0029] Width-limiting plates 600 for adjusting the channel width are provided on both the feeding channel 200 and the lifting basket 530. Referring to Figure 3 , a plurality of bearings 610 are fixedly installed on the width-limiting plate 600. The outer rings of the bearings 610 are fixed to the width-limiting plate 600 by welding or other means. A threaded rod 620 is fixedly installed on the inner ring of the bearing 610. The threaded rod 620 of the width-limiting plate 600 on the feeding channel 200 is threadedly connected to one side of the feeding channel 200, and a knob 630 is provided at the other end of the threaded rod 620. By rotating the knob 630 to rotate the threaded rod 620, the threaded rod 620 can be controlled to move axially on the feeding channel 200. In this way, the movement control of the width-limiting plate 600 is realized, and thus the width of the feeding channel 200 is adjusted. Among them, the structure of the width-limiting plate 600 on the lifting basket is the same as that of the width-limiting plate 600 on the feeding channel 200.

[0030] Referring to Figure 2 and Figure 3 , a limiting mechanism 700 for restricting the dropping of the outer ring of the bearing 610 is provided at the discharging end of the feeding channel 200. The limiting mechanism 700 includes a limiting cylinder 710 and a rubber block 720 installed on the piston rod of the limiting cylinder 710. Through the limiting mechanism 700, the outer ring workpiece of the bearing 610 can be restricted on the feeding channel 200, so that the workpieces fall into the scar-removing mechanism 100 at intervals, realizing an orderly scar-removing operation.

[0031] As Figure 4As shown, the scar-removing mechanism 100 includes a grinding assembly 110 and two threaded drive rollers 120 for driving the outer ring of the bearing 610 to move axially. The two threaded drive rollers 120 are arranged in parallel and driven to rotate by a motor. The end faces where the feed channel 200 and the discharge channel 300 are located are both perpendicular to the threaded drive rollers 120. During operation, the bearing 610 drops from the feed channel 200 between the two threaded drive rollers 120, and the central axis of the outer ring workpiece of the bearing 610 is arranged in parallel with the two threaded drive rollers 120. The rotation of the two threaded drive rollers 120 drives the outer ring workpiece of the bearing 610 to move axially.

[0032] Combined with the attached Figure 5 , the grinding assembly 110 includes a lifting cylinder 111, a grinding head 112 installed on the piston rod of the lifting cylinder 111, and a first sensor for controlling the lifting of the lifting cylinder 111. The lifting cylinder 111 is fixedly installed on a gantry 130. The grinding head 112 is located above the two threaded drive rollers 120 and between the two threaded drive rollers 120.

[0033] Among them, the first sensor is not shown in the figure. It can be installed at any position between the grinding head 112 and the feed channel 200. Its function is to control the lifting cylinder 111 to drive the grinding head 112 to move down for grinding when detecting the workpiece. However, it should be noted that according to different installation positions, the starting time of the lifting cylinder 111 is different. Specifically, the grinding head 112 moves down for grinding when the workpiece reaches below the grinding head 112. In addition, the limiting cylinder 710 can also be controlled by the first sensor, but the telescopic state of the limiting cylinder 710 is opposite to that of the lifting cylinder 111, that is, when the grinding head 112 moves down, the limiting cylinder 710 controls the rubber block 720 to contract so that the workpiece falls between the two threaded drive rollers 120.

[0034] The grinding head 112 includes a clamping jaw 1121 and a grinding block 1122. The clamping jaw 1121 is provided with a groove 1123. Clamping bolts 1124 are threadedly connected to both ends of the groove 1123. Both ends of the grinding block 1122 are fixed by the clamping bolts 1124 on both sides of the groove 1123. At the same time, by adjusting the clamping bolts 1124 on both sides, the position of the grinding block 1122 can also be adjusted to make the centering of grinding blocks 1122 with different widths achievable.

[0035] As Figure 6 and Figure 7 shown, the lifting mechanism 400 includes a lifting cylinder 410, a lifting plate 420 installed on the piston rod of the lifting cylinder 410, and a second sensor for controlling the lifting cylinder 410. The lifting plate 420 is arranged to be inclined downward towards the discharge channel 300. By the inclined arrangement, after the lifting plate 420 lifts the workpiece, the workpiece automatically rolls into the discharge channel 300 along the inclined direction.

[0036] In addition, a stopper 421 is provided at the high end of the lifting plate 420 to prevent the workpiece from rolling out of the lifting plate 420 towards the high end. And a vertical baffle 422 is provided on the lifting plate 420 to block and hold the workpiece on the lifting plate 420.

[0037] The discharge channel 300 is also inclined, with the feed end of the discharge channel 300 higher than the discharge end. A width-limiting plate 600 for adjusting the channel width is provided on the discharge channel 300, and the installation structure of the width-limiting plate 600 is the same as that of the width-limiting plate 600 on the feed channel 200.

[0038] As Figure 1 and Figure 6 shown, a transmission mechanism 800 is provided at the discharge end of the discharge channel 300, and the transmission mechanism 800 is a conveyor belt.

[0039] Referring to the appendix Figure 8 , the discharge end of the discharge channel 300 is closed, and a flipping structure is provided below the discharge end. The flipping structure includes an arc-shaped guide plate 310 and a limiting plate 320 located on the arc-shaped guide plate 310. The limiting plate 320 is connected to the width-limiting plate 600 in the discharge channel 300. During use, after the workpiece enters the discharge end of the discharge channel 300, it drops onto the arc-shaped guide plate 310. Due to the setting of the limiting plate 320, the upper end of the workpiece can only fall along the arc-shaped guide plate 310 and will not fall in the reverse direction, so that the workpiece can stably enter the transmission mechanism 800.

[0040] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
