Description

Technical Field

[0001] The invention relates to the technical field of bearing polishing, and in particular to a thin-walled bearing outer ring polishing device and a polishing process. Background Art

[0002] Bearings are a type of component in mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the coefficient of friction during their movement, and ensure their rotation accuracy. Among them, thin-walled bearings are bearings that achieve an extremely thin bearing cross-section and a miniaturized and lightweight design. Thin-walled bearings usually include an outer ring, an inner ring, a dust cover, and a number of rollers. As a part of the thin-walled bearing, the outer ring has a very thin wall thickness. The outer ring of the thin-walled bearing is machined using a turning process. After the outer ring of the bearing is machined, there will be some impurities such as burrs and iron filings on its surface. Therefore, the outer ring of the bearing also needs to be polished. In the prior art, grinding and polishing equipment is generally used to polish the outer ring of the bearing.

[0003] For example, the patent document with announcement number CN113524004B discloses a surface polishing device for processing bearing outer rings. The polishing device includes a fixing mechanism and a grinding assembly. The fixing mechanism includes a mounting bracket, a positioning block, a first electric push rod and a movable sleeve. The bearing outer ring is sequentially sleeved on the outside of the three mounting brackets and sequentially movably sleeved on the grooves of the positioning block. The first electric push rod pushes the movable sleeve to move. With the cooperation of the mounting bracket, the first spring and the second spring, multiple bearing outer rings are clamped at the same time, and then the grinding assembly grinds and polishes the bearing outer rings.

[0004] When the above-mentioned polishing device polishes the outer ring of a thin-walled bearing, due to the small wall thickness of the outer ring, the inside of the outer ring is fixed only by three positioning blocks on three mounting brackets. The grinding assembly will exert radial force on the outer ring during the polishing process of the outer ring, causing the outer ring to easily deform, affecting subsequent processing and production links. Summary of the invention

[0005] In view of this, the present invention provides a thin-walled bearing outer ring polishing device and a polishing process to solve the technical problem that the thin-walled bearing outer ring is easily deformed during the polishing process.

[0006] In order to solve the above technical problems, on the one hand, the present invention provides a thin-walled bearing outer ring polishing device, comprising a rotating drum and a polishing assembly arranged on a workbench, the rotating drum is driven by a driving member, and a plurality of clamping members are evenly spaced around the rotating drum; the clamping member comprises a base, two flexible support plates installed on the base, a capsule connected between the two support plates, and a pressure rod slidably arranged on the base and located above the capsule; the two support plates are both hollow structures, and an air cavity is formed between the two support plates, the capsule and the base; A moving tube is slidably provided in the rotating drum, and a sliding rod is slidably provided in the moving tube, and the moving tube and the sliding rod are driven by linear drivers respectively; an expansion piece 1 is installed on the moving tube, and an expansion piece 2 is installed on the sliding rod, and both the expansion piece 1 and the expansion piece 2 are frustum-shaped, and a blade passing through the rotating drum is installed on the base, and an inclined surface is provided at the end of the blade that can slide with the side of the expansion piece 1 or the expansion piece 2.

[0007] By adopting the above technical solution, when the clamping member clamps the outer ring, as the moving tube and the sliding rod move alternately, the expansion member 1 and the expansion member 2 alternately push the blade to move radially away from the axis of the outer ring, and the blade drives the base and the pressure rod to move in turn. When the pressure rod contacts the inner wall of the outer ring, as the blade drives the base to continue to move radially away from the axis of the outer ring, the pressure rod squeezes the capsule, increases the air pressure in the air cavity, and causes the flexible support plate to deform. The end face of the support plate is close to the inner wall of the outer ring, increasing the contact area between the support plate and the outer ring, which is conducive to reducing the deformation of the outer ring during the polishing process. At the same time, during the polishing process, the driving member drives the rotating drum to rotate, and the rotating drum drives the blade to rotate. The rotation of the blade generates airflow, which is conducive to reducing the heat generated by the friction between the outer ring and the polishing component during polishing, thereby helping to reduce the deformation of the outer ring; the clamping member alternately clamps the outer ring, which can change the position of the outer ring clamping, which is conducive to uniform heat dissipation of the outer ring, thereby helping to reduce the deformation of the outer ring, and at the same time, reducing the safety hazards to operators caused by excessive heat after polishing the outer ring.

[0008] Preferably, support members are installed at both ends of the base, elastic rings that can be sleeved on the support members are provided at both ends of the rotating drum, and a return spring is connected between the pressure rod and the support member.

[0009] By adopting the above technical solution, when the moving tube or the sliding rod moves in the reverse direction, the expansion member 1 or the expansion member 2 loses the force acting on the blade, the elastic ring resets the base, and the reset spring resets the pressure rod.

[0010] Preferably, a rotating shaft is rotatably provided on the workbench, a mounting plate is fixedly connected to the rotating shaft, a rotating drum is rotatably connected to the mounting plate, a baffle is installed on the mounting plate to limit the outer ring sleeved on the rotating drum, and a rotating cylinder is provided at one end of the rotating shaft to drive the rotating shaft to rotate.

[0011] By adopting the above technical solution, after multiple outer rings are sleeved on the rotating drum, the rotating cylinder drives the rotating shaft to rotate, and the rotating shaft drives the mounting plate and the rotating drum to tilt upward. Under the limiting action of the baffle, the outer rings are arranged on the rotating drum in an orderly manner, which is beneficial to reduce the inclination of the outer rings on the rotating drum, thereby helping to improve the stability of the outer ring clamping.

[0012] Preferably, a drop tube is provided on one side of the rotating drum, and a plurality of blocks capable of limiting the outer ring in the drop tube are installed at the end of the drop tube, and the blocks are flexible; a sliding frame is slidably provided on the workbench, and the rotating shaft is rotatably installed on the sliding frame, and the movement of the sliding frame is driven by a first screw adjustment mechanism arranged on the workbench.

[0013] By adopting the above technical scheme, the outer ring to be polished is transported to the blanking tube, the stop block limits the outer ring, the first screw adjustment mechanism drives the sliding frame to move, so that the rotating drum is extended into the blanking tube, and the outer ring is sleeved in the rotating drum. After the clamping part clamps and positions the outer ring, the first screw adjustment mechanism drives the sliding frame to move in the opposite direction, so that the rotating drum is separated from the blanking tube, which is conducive to realizing rapid loading of multiple outer rings and simultaneous polishing of multiple outer rings, which is conducive to improving polishing efficiency.

[0014] Preferably, the sliding frame and the blanking tube are both mounted on the mobile frame, the polishing assembly is arranged on one side of the mobile frame, a second screw adjustment mechanism capable of driving the mobile frame to move is arranged under the workbench, and the moving directions of the mobile frame and the sliding frame are perpendicular.

[0015] By adopting the above technical solution, the second screw adjustment mechanism drives the moving frame to move, the moving frame drives the sliding frame and the blanking tube to move, and then drives the rotating drum on the sliding frame to move, which is convenient for adjusting the distance between the rotating drum and the polishing assembly, and is beneficial for the polishing assembly to grind the outer ring on the rotating drum.

[0016] Preferably, a slide groove is provided on the movable tube, so that the expansion member 2 located between the two expansion members 1 passes through the slide groove and is connected to the slide rod.

[0017] By adopting the above technical solution, the expansion piece 2 located between the two expansion pieces 1 passes through the slide groove and is connected to the slide rod, so that it can follow the movement of the slide rod to achieve relative movement of the moving tube and the slide rod, thereby achieving alternating clamping of the outer ring by the clamping piece.

[0018] Preferably, a feed discharge port is provided on the workbench, and the feed discharge port is located on one side of the sliding frame. The rotary cylinder drives the rotating drum to tilt downward so that the outer ring on the rotating drum falls from the feed discharge port.

[0019] By adopting the above technical solution, after the polishing assembly polishes the outer ring, the first screw adjustment mechanism drives the rotating drum to move above the unloading port, the rotating cylinder drives the rotating drum to tilt downward, and the clamping part releases the clamping of the outer ring, thereby facilitating the unloading of the outer ring.

[0020] On the other hand, the present invention provides a thin-walled bearing outer ring polishing process, using the above-mentioned thin-walled bearing outer ring polishing device, comprising the following steps: Step 1: The linear actuator drives the moving tube and the sliding rod to move alternately, so that the clamping parts alternately clamp the outer ring sleeved on the rotating drum. During clamping, the expansion member 1 or the expansion member 2 pushes the blade to move, and the blade drives the base to move. When the pressure rod contacts the inner wall of the outer ring, the pressure rod squeezes the capsule, so that the support plate is deformed and supports the outer ring; Step 2: The driving member drives the drum to rotate, and drives the outer ring to rotate. The polishing assembly polishes the outer ring. The drum drives the blades to rotate. The airflow generated by the blades can drive the heat generated when the outer ring is polished.

[0021] By adopting the above technical scheme, the flexible support plate is deformed, and the contact area between the support plate and the outer ring is increased, which is beneficial to reduce the deformation of the outer ring during the polishing process; at the same time, the rotating drum drives the blades to rotate, and the rotation of the blades generates airflow, which is beneficial to reduce the heat generated by the friction between the outer ring and the polishing component during polishing, thereby helping to reduce the deformation of the outer ring; the clamping parts alternately clamp the outer ring, which can change the clamping position of the outer ring, which is beneficial to uniform heat dissipation of the outer ring, thereby helping to reduce the deformation of the outer ring. At the same time, it can also reduce the safety hazards to operators caused by excessive heat after polishing of the outer ring.

[0022] The beneficial effects of the above technical solution of the present invention are as follows: 1. The flexible support plate of the present invention can be deformed to increase the contact area between the support plate and the outer ring, which is beneficial to reducing the deformation of the outer ring during the polishing process; at the same time, the rotating drum drives the blades to rotate, and the rotation of the blades generates airflow, which is beneficial to reducing the heat generated by the friction between the outer ring and the polishing component during polishing, thereby helping to reduce the deformation of the outer ring; the clamping parts alternately clamp the outer ring, which can change the clamping position of the outer ring, which is beneficial to uniform heat dissipation of the outer ring, thereby helping to reduce the deformation of the outer ring, and at the same time, it can also reduce the safety hazards to operators caused by excessive heat after polishing the outer ring.

[0023] 2. The rotary cylinder of the present invention can drive the rotating drum to tilt upward and downward. The upward tilt of the rotating drum is conducive to the orderly arrangement of the outer rings on the rotating drum, reducing the inclination of the outer rings on the rotating drum, thereby helping to improve the stability of the outer ring clamping; the downward tilt of the rotating drum is conducive to the unloading of the polished outer rings.

[0024] 3.

[0031] like Figure 1 and Figure 2 As shown, a sliding frame 11 and a first screw adjustment mechanism 12 are provided on the moving frame 14, and the first screw adjustment mechanism 12 drives the sliding frame 11 to move. The first screw adjustment mechanism 12 includes a first screw 121 rotatably mounted on the moving frame 14, and a first screw slider 122 slidably arranged on the first screw 121. The first screw 121 is driven by a first screw motor 123, and the first screw slider 122 is fixedly connected to the sliding frame 11. The lower end surface of the first screw slider 122 is slidably connected to the moving frame 14, and the axial direction of the first screw 121 is perpendicular to the axial direction of the second screw 151, so that the moving direction of the sliding frame 11 is perpendicular to the moving direction of the moving frame 14.

[0032] like Figure 2 and Figure 5 As shown, a rotating shaft 111 is rotatably connected to the sliding frame 11, and the axial direction of the rotating shaft 111 is perpendicular to the axial direction of the first screw 121. A rotating cylinder 114 is provided on the sliding frame 11, and the rotating cylinder 114 is located at one end of the rotating shaft 111 and can drive the rotating shaft 111 to rotate.

[0033] like Figure 2 and Figure 5 As shown, a mounting plate 112 is fixedly connected to the rotating shaft 111, and a rotating drum 2 is rotatably connected to the mounting plate 112, and the axial direction of the rotating drum 2 is perpendicular to the axial direction of the rotating shaft 111. The rotating drum 2 is driven by a driving member 5, and a sleeve (not shown in the figure) is installed at the end of the rotating drum 2. The driving member 5 includes a driving motor 51 installed on the mounting plate 112 and two mutually meshing gears 52 installed on the output shaft of the driving motor 51 and the sleeve.

[0034] like Figure 6 As shown, six clamping members 3 are evenly distributed around the circumference of the drum 2, and the six clamping members 3 are alternately distributed in two groups. The clamping member 3 includes a base 31, a support plate 32, a capsule 33 and a pressure rod 34.

[0035] Among them, Figure 6As shown, the base 31 is U-shaped. Two support plates 32 are provided, and both are flexible hollow structures. The two support plates 32 are located on both sides of the base 31. The two support plates 32 are arranged facing each other and both have an upper plate surface and a lower plate surface. One side of the upper plate surface and the lower plate surface has an opening. The openings of the two upper plate surfaces are connected to the capsule 33, and the openings of the two lower plate surfaces are connected to the base 31, so that an air cavity 35 is formed between the two support plates 32, the capsule 33 and the base 31.

[0036] like Figure 6 and Figure 8 As shown, the pressure rod 34 is located above the capsule 33, and left and right support members 37 are installed at both ends of the base 31. The support member 37 is rod-shaped and has a hook (not shown in the figure), and a return spring 39 is connected between the support member 37 and the pressure rod 34. Both ends of the rotating drum 2 are provided with elastic rings 38, and the elastic rings 38 are sleeved on the hooks of the support member 37.

[0037] like Figure 5 and Figure 7 As shown, a moving tube 21 is slidably installed in the rotating drum 2, and a sliding rod 22 is slidably installed in the moving tube 21. The axes of the sliding rod 22, the moving tube 21 and the rotating drum 2 are collinear. Two linear actuators 23 are installed on the mounting plate 112, and the two linear actuators 23 drive the moving tube 21 and the sliding rod 22 to move respectively. The linear actuator 23 is a cylinder or a hydraulic cylinder.

[0038] like Figure 6 and Figure 7 As shown, an expansion piece 1 24 is installed on the moving tube 21, and an expansion piece 25 is installed on the slide bar 22. Both the expansion piece 1 24 and the expansion piece 25 are of a frustum type. A through hole is opened on the rotating drum 2, and a blade 36 penetrating the through hole is installed on the base 31. The blade 36 extends into the rotating drum 2, and the end of the blade 36 is provided with an inclined surface that can slide with the side of the expansion piece 1 24 or the expansion piece 25. The movement of the expansion piece 1 24 or the expansion piece 25 can push the blade 36 to move radially away from the axis of the rotating drum 2.

[0039] like Figure 6 and Figure 7 As shown, multiple expansion pieces 1 24 and expansion pieces 2 25 are provided and arranged alternately. The slide bar 22 penetrates the moving tube 21, and the moving tube 21 is provided with a slide groove 211. The expansion piece 25 located between the two expansion pieces 1 24 penetrates the slide groove 211 and is fixedly connected to the slide bar 22, so that the expansion piece 25 moves with the slide bar 22, and the moving tube 21 and the slide bar 22 move relative to each other, so that the clamping piece 3 alternately clamps the outer ring.

[0040] like Figure 6 and Figure 7As shown, the outer ring is sleeved on the rotating drum 2, and with the alternating movement of the moving tube 21 and the sliding rod 22, the expansion piece 1 24 and the expansion piece 2 25 alternately push the blade 36 to move radially away from the axis of the outer ring, and the blade 36 drives the base 31 and the pressure rod 34 to move in turn. When the pressure rod 34 contacts the inner wall of the outer ring, as the blade 36 drives the base 31 to continue to move radially away from the axis of the outer ring, the pressure rod 34 squeezes the capsule 33, so that the air pressure in the air cavity 35 increases and the flexible support plate 32 is deformed. The end face of the support plate 32 is close to the inner wall of the outer ring, so that the contact area between the support plate 32 and the outer ring is increased, which is beneficial to reduce the deformation of the outer ring during the polishing process.

[0041] During the polishing process, Figure 2 and Figure 6 As shown, the driving member 5 drives the drum 2 to rotate, and the drum 2 drives the blades 36 to rotate. The rotation of the blades 36 generates airflow, which is beneficial to reducing the heat generated by the friction between the outer ring and the polishing component 4 during polishing, thereby helping to reduce the deformation of the outer ring; the clamping member 3 alternately clamps the outer ring, which can change the clamping position of the outer ring, which is beneficial to uniform heat dissipation of the outer ring, thereby helping to reduce the deformation of the outer ring, and at the same time, reducing the safety hazard to the operator caused by excessive heat after polishing the outer ring.

[0042] like Figure 7 and Figure 8 As shown, when the moving tube 21 or the sliding rod 22 moves in the opposite direction, the expansion member 1 24 or the expansion member 2 25 loses the force acting on the blade 36, the elastic ring 38 resets the base 31, and the reset spring 39 resets the pressure rod 34.

[0043] like Figure 5 As shown, a plurality of baffles 113 are mounted on the mounting plate 112 to limit the outer rings sleeved on the rotating drum 2. After the plurality of outer rings are sleeved on the rotating drum 2, the rotating cylinder 114 drives the rotating shaft 111 to rotate, and the rotating shaft 111 drives the mounting plate 112 and the rotating drum 2 to tilt upward. Under the limiting effect of the baffles 113, the outer rings are arranged in order on the rotating drum 2, which is conducive to reducing the inclination of the outer rings on the rotating drum 2, thereby facilitating improving the stability of the outer ring clamping.

[0044] like Figure 1 and Figure 3 As shown, a drop pipe 13 is provided on one side of the drum 2, and the drop pipe 13 is installed on a moving frame 14. The drop pipe 13 has an inclined section and a horizontal section. A plurality of stoppers 131 capable of limiting the outer ring in the drop pipe 13 are installed at the end of the drop pipe 13, and the stoppers 131 are flexible.

[0045] like Figure 1 As shown, the outer ring to be polished is transported into the blanking tube 13, as shown in FIG. Figure 3 As shown, the stopper 131 limits the outer ring, as shown in FIG. Figure 2As shown, the first screw adjustment mechanism 12 drives the sliding frame 11 to move, so that the rotating drum 2 extends into the blanking tube 13, and the outer ring is set in the rotating drum 2. Figure 6 As shown, after the clamping member 3 clamps and positions the outer ring, the first screw adjustment mechanism 12 drives the sliding frame 11 to move in the opposite direction, so that the rotating drum 2 is separated from the blanking tube 13, which is conducive to rapid loading of multiple outer rings and simultaneous polishing of multiple outer rings, thereby improving polishing efficiency.

[0046] like Figure 1 and Figure 3 As shown, the workbench 1 is provided with a material discharge port 16, and the material discharge port 16 is located on one side of the sliding frame 11. Figure 5 As shown, the rotary cylinder 114 drives the drum 2 to tilt downward so that the outer ring on the drum 2 falls from the discharge port 16.

[0047] like Figure 1 As shown, after the polishing assembly 4 polishes the outer ring, Figure 3 As shown, the first screw adjustment mechanism 12 drives the drum 2 to move above the discharge port 16, as shown in FIG. Figure 5 As shown, the rotary cylinder 114 drives the drum 2 to tilt downward, as shown in FIG. Figure 6 As shown, the clamping member 3 releases the clamping of the outer ring, making it easier to cut the outer ring.

[0048] A thin-walled bearing outer ring polishing process, using the above-mentioned thin-walled bearing outer ring polishing device, comprises the following steps: Step 1: The outer ring to be polished is transported into the blanking tube 13, the stopper 131 limits the outer ring, the first screw adjustment mechanism 12 drives the sliding frame 11 to move to the side close to the blanking tube 13, so that the rotating drum 2 extends into the blanking tube 13, and the outer ring is sleeved in the rotating drum 2. After the clamping member 3 clamps and positions the outer ring, the first screw adjustment mechanism 12 drives the sliding frame 11 to move to the side away from the blanking tube 13, so that the rotating drum 2 is separated from the blanking tube 13; during clamping, the linear drive 23 drives the moving tube 21 or the sliding rod 22 to move, so that the expansion member 1 24 or the expansion member 2 25 pushes the blade 36 to move radially away from the axis of the outer ring, and the blade 36 drives the base 31 and the pressure rod 34 to move synchronously. When the pressure rod 34 contacts the inner wall of the outer ring, the pressure rod 34 squeezes the capsule 33, so that the air pressure in the air cavity 35 increases, so that the support plate 32 is deformed and supports the outer ring; Step 2: The linear drive 23 drives the moving tube 21 or the sliding rod 22 to move in the opposite direction, so that the clamping member 3 releases the clamping of the outer ring; the rotating cylinder 114 is started, and the rotating cylinder 114 drives the rotating shaft 111 to rotate, so that the rotating shaft 111 drives the mounting plate 112 and the rotating drum 2 to tilt upward. Under the limiting action of the baffle 113, the outer rings are arranged in order on the rotating drum 2, and the linear drive 23 drives the moving tube 21 or the sliding rod 22 to move, so that the clamping member 3 clamps the outer ring; the rotating cylinder 114 is started to keep the axis of the rotating drum 2 in a horizontal state; the second screw adjustment mechanism 15 is started to adjust the distance between the polishing wheel 41 and the outer ring; Step 3: The driving member 5 drives the drum 2 to rotate, and drives the outer ring to rotate, the polishing assembly 4 polishes the outer ring, the drum 2 drives the blades 36 to rotate, and the airflow generated by the blades 36 can drive the heat generated when the outer ring is polished; the first screw adjustment mechanism 12 drives the outer ring to move, so that the outer rings on the drum 2 are polished in turn; Step 4: After polishing is completed, the first screw adjustment mechanism 12 drives the drum 2 to move above the unloading port 16, and the rotary cylinder 114 drives the drum 2 to tilt downward, and the clamping member 3 releases the clamping of the outer ring to realize unloading of the outer ring.

[0049] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components.
