Description

[0002] In the automotive manufacturing industry, roller bearings are key transmission components, and the surface grinding precision of their bearings directly affects the stability and service life of the entire vehicle. Therefore, the requirements for the efficiency, adaptability and accuracy of grinding equipment are becoming increasingly stringent.

[0003] However, existing automotive roller bearing grinding devices still have many technical shortcomings: First, bearing transport relies heavily on manual assistance or simple transport mechanisms, requiring manual transfer and positioning of the bearing to be ground to the grinding station. This is not only labor-intensive but also lacks transport accuracy, easily leading to grinding deviations and severely affecting production efficiency and product consistency. Second, the clamping mechanism has a fixed structure and extremely poor adaptability, only capable of clamping bearings of a single specification. When dealing with roller bearings of different inner and outer diameters, frequent disassembly and adjustment of the equipment are required, making the operation cumbersome and time-consuming, significantly reducing production continuity. Third, the position and angle adjustment of the grinding components in the grinding assembly are limited, and the grinding range is fixed, making it difficult to accurately cover key parts such as the outer surface and side edges of the bearing, resulting in insufficient grinding precision and failing to meet the requirements of high-precision processing.

[0023] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0024] The following description, with reference to the accompanying drawings, depicts an automotive roller bearing grinding apparatus according to an embodiment of this application.

[0025] like Figures 1-14 As shown, the automotive roller bearing grinding device according to an embodiment of this application includes a body 100, such as... Figures 1 to 7 As shown, a collection chamber 110 is installed at the bottom of the inner cavity of the machine body 100. The collection chamber 110 is used to collect the powder generated after grinding and polishing. A roller conveyor 200 is installed on the left side of the inner cavity of the machine body 100 and on the right side of the polishing component 500 and the grinding component 600. The roller conveyor 200 is used to convey the roller bearing after grinding and polishing.

[0026] like Figure 3 and Figure 4 As shown, a linear motor 120 is longitudinally mounted on the left side of the inner cavity of the machine body 100, while a sliding roller assembly 130 is mounted on the left side of the inner cavity of the machine body 100 and to the right of the linear motor 120. The roller bearing to be initially ground is placed in the sliding roller assembly 130. A shifting component 121 is movably connected to the output end of the linear motor 120, and the shifting component 121 can move linearly on the linear motor 120.

[0027] The shifting component 121 consists of a connecting seat, a dial motor, and a dial. The connecting seat is connected to the output end of the linear motor 120 to drive the connecting seat to slide on the surface of the linear motor 120. The dial motor is bolted to one end of the connecting seat, and the output end of the dial motor is connected to the dial, so that the dial can be tilted by the dial motor.

[0028] In actual use, the roller bearing is placed on the sliding roller group 130, and the linear motor 120 controls the movement of the shifting component 121. The dial in the shifting component 121 can transport the roller bearing placed on the sliding roller group 130 backward until it is below the clamping module 141.

[0029] Meanwhile, a linear motor 2 140 is installed on the rear right side of the machine body 100 via a support frame. The output end of the linear motor 2 140 is connected to a clamping module 1 141, which is a robotic arm with a gripper capable of multi-angle movement. The linear motor 2 140 can drive the clamping module 1 141 to linearly move. The clamping module 1 141 can clamp the roller bearing to be polished on the surface of the sliding roller group 130. With the cooperation of the clamping module 1 141 and the linear motor 2 140, the roller bearing can be sent into the adjustable clamping group 400 for subsequent positioning and conveying of the roller bearing using the adjustable clamping group 400.

[0030] like Figure 5 As shown, in practical applications, a clamping module 2 150 is mounted on the rear side of the inner cavity of the machine body 100 and on the left side of the grinding assembly 600. The clamping module 2 150 has the same structure as the clamping module 1 141. At the same time, a blowing component 170 is installed in front of the clamping module 2 150 and on the front side of the inner cavity of the machine body 100. The bottom of the blowing component 170 is supported by the mounting bracket 160. The blowing component 170 consists of a telescopic cylinder and an air pump. The telescopic cylinder can drive the air pump to move linearly. The mounting bracket 160 can support the telescopic cylinder. The air pump can blow the surface of the roller bearing that has been ground after passing through its position and is conveyed by the roller conveyor 200. The brushed roller bearing is sent out of the grinding device through the roller conveyor 200.

[0031] Two reciprocating moving seats 300 are symmetrically arranged along the axis on the right side of the inner cavity of the machine body 100. The reciprocating moving seats 300 are fastened to both sides of the inner cavity of the machine body 100 by bolts. An adjustable clamping group 400 capable of reciprocating motion is movably arranged on the opposite side of the two reciprocating moving seats 300. The adjustable clamping group 400 is used for positioning and conveying when grinding the automotive roller bearing. There are multiple adjustable clamping groups 400, which are arranged in the inner cavity of the assembly slot 301. A grinding component 600 is arranged in the middle of the inner cavity of the machine body 100. The grinding component 600 is used to grind the roller bearing. Among them, such as Figure 13 and Figure 14 As shown, the adjustable clamping assembly 400 includes a pin 450 and a bearing plate 460 arranged opposite to each other. The pin 450 is movably mounted on an adjacent push rod 430 via a mounting sleeve 440, while the bearing plate 460 is movably mounted on an adjacent push rod 430 via a connecting plate 461. Both push rods 430 are engaged with a chain 310 via a sprocket 420 located at one end of a bearing seat 410. The chain 310 rotates under force, driving the sprocket 420 to drive the adjacent push rod 430. A turntable 470 is rotatably mounted inside the bearing plate 460. The inner surface of the carrier plate 460 is provided with multiple straight-moving grooves 462, while the surface of the turntable 470 is provided with a pushing groove 471. A straight-moving plate 480 is slidably arranged in the inner cavity of the straight-moving groove 462. A connecting rod 481 is slidably contacted in the inner cavity of the pushing groove 471. The connecting rod 481 and the opposite side of the straight-moving plate 480 are fixedly connected. The connecting rod 481, in conjunction with the pushing groove 471, adjusts the position of the straight-moving plate 480 in order to change the position of the connecting guide plate 490 and the abutment plate 491, thereby adjusting the position of the abutment plate 491 tightly against the side of the roller bearing. In use, by rotating the turntable 470 and limiting it under the straight-moving groove 462, the push groove 471 opened therein can push the adjacent connecting rod 481 to move, thereby driving the straight-moving plate 480 to move linearly within the straight-moving groove 462, and driving the connecting guide plate 490 and the abutment plate 491 to move, thereby changing the position of the abutment plate 491 so that it can be used in conjunction with the insertion rod 450 to clamp the relative position on the side of the roller bearing. For example, when clamping a larger roller bearing, by unfolding the abutment plate 491 outward, a wider range of the side of the roller bearing can be clamped. Similarly, by retracting the abutment plate 491 inward, a narrower range of the side of the roller bearing can be clamped.

[0032] Meanwhile, when it is necessary to grind the side edge of the roller bearing, the abutment plate 491 retracts inward to clamp the center of the side of the roller bearing, exposing the side edge of the roller bearing, which can be used with the grinding disc on the grinding disc carrier plate 680 to grind the side edge of the roller bearing.

[0033] Among them, the straight-moving plate 480 extends through one end of the bearing plate 460 and is connected to the abutment plate 491 via the connecting guide plate 490. The abutment plate 491, together with the insertion rod 450, positions both sides of the roller bearing.

[0034] The end of the connecting rod 481 away from the straight-moving plate 480 is connected to an L-shaped plate 492. The L-shaped plate 492 can press tightly against the inner wall of the roller bearing, thereby cooperating with the abutment plate 491 to stably limit the roller bearing. Furthermore, under the action of the turntable 470, the relative positions between multiple L-shaped plates 492 can also be changed, so that they can be adapted to the inner diameter size of roller bearings of different specifications.

[0035] In practical applications, the end of the L-shaped plate 492 that connects to the connecting rod 481 can be connected by a telescopic structure. For example, the end of the connecting rod 481 that connects to the L-shaped plate 492 can be connected by a telescopic sleeve. The telescopic sleeve is limited by bolts, thereby assisting in the manual adjustment of the relative positions between multiple L-shaped plates 492.

[0036] The reciprocating moving seat 300 has an assembly groove 301 in its inner cavity, and a chain 310 is movably installed in the inner cavity of the assembly groove 301. Both ends of the inner surface of the two chains 310 are fitted with shafts, one end of which extends through the outer side of the chain 310. The end of the shaft that connects to the chain 310 is in contact with the chain through a bearing. One end of the reciprocating moving seat 300 is connected to a geared motor, which drives the adjacent shaft. The fixed end of the geared motor is fastened to the surface of the reciprocating moving seat 300 by bolts. At the same time, the output end of the reciprocating moving seat 300 is connected to one end of the adjacent shaft. Specifically, both shafts are connected to synchronous pulleys, which are connected by a synchronous belt. The end of the synchronous belt near the sprocket is connected to the opposite side of the chain 310 via multiple connecting rods. Thus, when the geared motor is working, it can drive the shaft to rotate, which in turn drives the synchronous belt through the synchronous pulleys on the shaft surface. This drives the chain 310 through the connecting rods, which in turn drives the chain 310. The chain 310, in conjunction with the sprocket 420, drives the bearing seat 410, and finally drives the other components in the adjustable clamping assembly 400 to move.

[0037] In practical applications, a chain condition with the same shape as the chain 310 is installed on the outer side of the inner surface of the assembly groove 301. This chain condition can be fixed on the inner surface of the assembly groove 301, and the sprocket 420 meshes with the adjacent chain 310 and chain condition, thereby increasing the stability of the sprocket 420 when it moves.

[0038] In practical applications, the chain 310 can be replaced with a belt, and a pulley is fitted on the surface of the shaft. The two pulleys are connected by belt drive, and the bearing seat 410 is connected to the pulley by a connecting rod. In addition, a loop-shaped cavity with the same shape as the belt is opened at one end of the assembly groove 301 cavity in the reciprocating moving seat 300. One end of the connecting rod connected to the belt extends into the loop-shaped cavity. When the belt drives the connecting rod to move, its shaft end slides in the loop-shaped cavity, thereby increasing the stability of the parts moving in the polishing assembly 500.

[0039] The adjustable clamping assembly 400 also includes a push rod 430, wherein the fixed end of the push rod 430 is connected to a bearing seat 410, and one end of the bearing seat 410 is connected to a sprocket 420 via a rotating rod. The end of the rotating rod connected to the bearing seat 410 is movably connected via a bearing, and the sprocket 420 meshes with the adjacent chain 310, thereby driving the sprocket 420 to move when the chain 310 moves. Specifically, such as Figure 13 and Figure 14 As shown, the output ends of two oppositely arranged push rods 430 are respectively connected to a mounting sleeve 440 and a connecting plate 461. The mounting sleeve 440 and the connecting plate 461 are used to install the bearing plate 460 and the insert rod 450, respectively. The outer surface of the insert rod 450 extends to the inner surface of the mounting sleeve 440 and is threaded to it to facilitate quick disassembly and replacement of insert rods 450 of different sizes. The connecting plate 461 is connected to the opposite side of the bearing plate 460 so that the bearing plate 460 can be installed at the output end of the adjacent push rod 430 through the connecting plate 461.

[0040] In this solution, the position of the adjacent connecting guide plate 490 and the insertion rod 450 can be changed by the push rod 430. The connecting guide plate 490 and the insertion rod 450 are used to transport and position the roller bearing during grinding, so that the adjustable clamping assembly 400 can be adapted to roller bearings of different sizes.

[0041] As a further optimization of this solution, a transmission wheel set 463 is mounted on the surface of the bearing disk 460. The transmission wheel set 463 consists of a drive motor, a gear transmission component, and a gear ring transmission component. The drive motor is fixedly mounted on the surface of the bearing disk 460, the gear transmission component is mounted on the output shaft of the drive motor, and the gear ring transmission component is sleeved on the outer surface of the turntable 470. Thus, when the drive motor is working, it can drive the gear transmission component to rotate and drive the gear ring transmission component to rotate, thereby driving the turntable 470 to rotate to a certain angle, thereby changing the position of the abutment plate 491. In practical applications, to reduce costs, the drive motor can also be replaced with a throttle handle. The position of the abutment plate 491 can be changed by manually adjusting the grip, rotating, and shaking. If a throttle handle is used, a limiting structure, such as a snap-fit ​​sleeve, is required to limit the throttle handle. The limiting structure is existing technology and will not be described in detail in this solution.

[0042] In actual use, the two push rods 430 that are set opposite to each other can be used with the same abutment plate 491, or they can be used with the same insertion rod 450. This solution uses the abutment plate 491 in conjunction with the insertion rod 450 according to the shape of the roller bearing.

[0043] like Figures 2 to 7 and Figure 9As shown, the grinding assembly 600 is installed in the middle of the inner cavity of the machine body 100 via a connecting frame. An electric push rod can be installed on the top of the connecting frame. The output end of the electric push rod is connected to the surface of the connecting frame, while the fixed end of the electric push rod is connected to the top of the inner cavity of the machine body 100 by bolts. The grinding assembly 600 includes a grinding disc 630 for grinding the outer surface of the roller bearing, and the grinding disc 630 is sleeved on the drive rod. The grinding disc 630 is driven by a drive structure, such as... Figure 9 As shown, the drive structure includes a second drive motor 610 mounted above the grinding disc 630. Both the output end of the second drive motor 610 and the transmission rod shaft end of the grinding disc 630 are fitted with a second synchronous pulley set 620. The second synchronous pulley set 620 consists of two synchronous pulleys and a synchronous belt. The two synchronous pulleys are evenly meshed with the synchronous belt. Thus, when the second drive motor 610 rotates, it can drive the second synchronous pulley set 620 to move, which in turn drives the transmission rod and the grinding disc 630 to rotate, thereby grinding the roller bearing located below it.

[0044] The fixed end of the drive motor 610 and the surface of the transmission rod at the grinding disc 630 are both connected to the inner wall of the connecting frame through the bracket, thereby fixing the drive motor 610 and the grinding disc 630. The transmission rod at the grinding disc 630 is movably connected to the bracket through the bearing.

[0045] Both ends of the drive rod of the grinding disc 630 are fitted with ring plates 640, such as Figure 11 and Figure 12 As shown, each of the two ring plates 640 has a mounting groove 641 on its opposite side. The mounting groove 641 is used to install the grinding disc carrier plate 680. The surface of the ring plate 640 has multiple limiting grooves 642 that are connected to the inner cavity of the mounting groove 641.

[0046] Meanwhile, a sliding ring groove 644 is provided at one end of the two ring plates 640 facing each other. The sliding ring groove 644 is used in conjunction with the sliding ring plate 651. A plurality of snap-fit ​​grooves 643 are provided on the outer surface of the ring plate 640. The snap-fit ​​grooves 643 are used in conjunction with the plug-in paddle 670.

[0047] The inner surface of the slip ring groove 644 is connected to the ring plate 650 via the slidably disposed slip ring plate 651. A plurality of plug-in paddles 670 are connected to one side of the ring plate 650. The plug-in paddles 670 are flexible and are inserted into the snap-fit ​​groove 643. The plug-in paddles 670 cooperate with the snap-fit ​​groove 643 to limit the ring plate 650.

[0048] When in use, the plug-in lever 670 is inserted into the snap-fit ​​groove 643 to prevent the ring plate 650 from rotating at will. When it is necessary to rotate the ring plate 650 to cooperate with the push support plate 660 to push the position of the push block 661, simply pull the plug-in lever 670 out of the corresponding snap-fit ​​groove 643 to rotate the ring plate 650.

[0049] The surface of the ring plate 650 is rotatably connected to a pusher plate 660, and the other end of the pusher plate 660 is rotatably connected to a pusher block 661. The side of the pusher block 661 away from the pusher plate 660 passes through the limiting groove 642 via a cylindrical rod and is connected to the grinding disc carrier plate 680. The grinding disc carrier plate 680 is used to install the grinding disc, so that the grinding disc can be flexibly disassembled and replaced.

[0050] Specifically, such as Figure 11 As shown, the surface of the grinding disc carrier plate 680 is provided with mounting screw grooves, which can be used with screws to mount the grinding discs onto the surface of the grinding disc carrier plate 680. This allows the grinding discs to be used to grind the side edges of the roller bearing.

[0051] In practical use, to grind different positions on the side of the roller bearing, the ring plate 650 is rotated. The ring plate 650 can cooperate with the push support plate 660 to push the adjacent push block 661 to move the grinding disc carrier plate 680, so that multiple grinding disc carrier plates 680 can be relatively unfolded or extended. When multiple grinding disc carrier plates 680 are unfolded outward, they can cooperate with the grinding disc to grind the wider part of the side of the roller bearing. When multiple grinding disc carrier plates 680 are retracted inward, they can cooperate with the grinding disc to grind the edge of the side of the roller bearing.

[0052] Even after grinding, the surface of the roller bearing is still not smooth. To increase the smoothness of the roller bearing surface, such as... Figures 3 to 8 As shown, a polishing component 500 is provided in the inner cavity of the body 100 and on the left side of the reciprocating moving seat 300. The polishing component 500 assists in polishing the roller bearing when the grinding component 600 grinds it. The polishing component 500 is located below the grinding component 600.

[0053] Specifically, the polishing assembly 500 includes a drive belt 550, which is located above the collection chamber 110. Drive shafts 520 are installed through both sides of the inner cavity of the drive belt 550, and levers 530 are provided on opposite sides of the two drive shafts 520. Both the drive shaft 520 and the lever 530 extend to the outside of the mounting base plate 560. Bearing brackets are movably fitted at both ends of the drive shaft 520 and the lever 530 to assist in supporting the drive shaft 520 and the lever 530. A drive motor 510 is mounted on the shaft end of the drive shaft 520 via a bracket. A synchronous pulley set 540 is fitted on the output end of the drive motor 510 and the shaft ends of the drive shaft 520 and the lever 530. The synchronous pulley set 540 consists of three synchronous pulleys and a synchronous belt. The three synchronous pulleys are respectively fitted on the output end of the drive motor 510 and the shaft ends of the drive shaft 520 and the lever 530. Adjacent synchronous pulleys are connected by a synchronous belt.

[0054] Specifically, the surface of the transmission belt 550 is dynamically bonded with a polished belt, for example by Velcro or by bolts, and the polished belt is replaceable.

[0055] Thus, when the drive motor 510 is working, it can drive the transmission shaft 520 and the lever 530 to rotate through the synchronous pulley set 540. The rotation of the transmission shaft 520 can drive the transmission belt 550 to move, while the rotation of the lever 530 and the interlaced protrusions on its surface can move the transmission belt 550 back and forth, causing it to vibrate and increasing the polishing effect of the polishing belt on the roller bearing. At the same time, the vibration of the transmission belt 550 can shake off its surface debris and collect it in the collection bin 110.

[0056] Meanwhile, two mounting base plates 560 of the same shape are provided on both sides of the transmission belt 550. The mounting base plates 560 are installed on both sides of the inner cavity of the machine body 100 and located above the collection chamber 110. A dust suction groove 561 is provided through the middle of the surface of the mounting base plate 560 for discharging the polished impurities into the collection chamber 110 for collection.

[0057] Specifically, a dustproof and explosion-proof fan can be installed at the collection chamber 110. The dustproof and explosion-proof fan is existing technology and will not be described in detail in this solution. The air inlet of the dustproof and explosion-proof fan is connected to the cavity of the dust collection tank 561 through a pipe, and the output end of the dustproof and explosion-proof fan is connected to the inner cavity of the collection chamber 110 through a pipe. In this way, when the dustproof and explosion-proof fan is working, it can suck the debris and dust generated during grinding into the collection chamber 110 for collection.

[0058] In practical use, this solution is equipped with a controller and is electrically connected to the linear motor 120, linear motor 2 140, the dial motor of the shifting component 121, the clamping module 141, the clamping module 2 150, the transmission wheel group 463 of the adjustable clamping group 400, the push rod 430, the geared motor of the reciprocating moving seat 300, the drive motor 2 610 of the grinding component 600, the electric push rod on the top of the connecting frame, the telescopic cylinder and air pump of the blowing component 170, and the dustproof and explosion-proof fan, so as to achieve centralized and coordinated control. After the controller is programmed, it can automatically receive feedback signals from various components and issue precise instructions: control linear motor 120 and dial motor to complete bearing transport, regulate the clamping and transfer actions of linear motor 140, clamping module 141, and clamping module 150, synchronously start and stop the geared motor to drive the adjustable clamping group 400 to reciprocate, coordinate drive motor 610, electric push rod and ring plate 650 to complete precise grinding, and finally control telescopic cylinder, air pump and dustproof and explosion-proof fan to operate in an orderly manner, ensuring that all electrical components work together efficiently according to the process, and improving the accuracy and stability of the device's automated control.

[0059] Specifically, the working principle of this automotive roller bearing grinding device is as follows: Initially, the roller bearing to be ground is placed into the sliding roller assembly 130. Linear motor 120 controls the movement of the shifting component 121, which, via a dial, transports the roller bearing backward to below the clamping module 141. Subsequently, linear motor 2 140 on the rear right support of the machine body 100 drives the clamping module 141, which acts as a robotic arm, to move. The clamping module 141 clamps the roller bearing and feeds it into the adjustable clamping assembly 400. The adjustable clamping assembly 400, by rotating the turntable 470 and under the limit of the straight-moving groove 462, pushes the connecting rod 481 through the pushing groove 471, causing the straight-moving plate 480, connecting guide plate 490, and abutment plate 491 to move. This, in conjunction with the insertion rod 450 and the L-shaped adjustment mechanism (which can be adjusted via a telescopic structure), facilitates the movement of the roller bearing. The forming plate 492 positions roller bearings of different specifications, and the push rod 430 can adjust the position of related components to adapt to roller bearings of different sizes. Then, the geared motor on the reciprocating moving seat 300 drives the shaft to rotate, which drives the chain 310 to move through the synchronous pulley and synchronous belt. The chain 310 meshes with the sprocket 420 to drive the bearing seat 410 and the adjustable clamping assembly 400 to reciprocate as a whole, realizing the positioning and conveying of the roller bearing. During the conveying process, the second drive motor 610 of the grinding assembly 600 drives the grinding disc 630 to rotate through the second synchronous pulley assembly 620. At the same time, the plug-in paddle 670 can be lifted to disengage from the locking groove 643. The rotating ring plate 650 adjusts the unfolding or retracting state of the grinding disc carrier plate 680 through the pushing support plate 660 and the pushing block 661, and uses the grinding disc to grind the outer surface and side edges of the roller bearing. During grinding, the drive motor 510 of the polishing assembly 500 drives the transmission shaft 520 and the lever 530 to rotate via the synchronous pulley set 540. The transmission shaft 520 drives the transmission belt 550 to move, and the lever 530 causes the transmission belt 550 to vibrate. The polishing belt on its surface assists in polishing the roller bearing. The debris generated by the vibration and the powder generated by grinding are sucked into the collection chamber 110 by the dust suction groove 561 of the mounting base plate 560 and collected together under the action of the dustproof and explosion-proof fan at the collection chamber 110. After grinding and polishing, the clamping module 150 cooperates to transfer the roller bearing to the roller conveyor 200. When the roller conveyor 200 conveys the roller bearing past the blowing component 170, it blows the surface of the roller bearing. Finally, the roller bearing is sent out of the grinding device by the roller conveyor 200.
