Description

Technical Field

[0001] The utility model relates to the technical field of machining, and specifically relates to a double-station turning mechanism for the surface of a rubber-coated pulley of a bearing. Background Art

[0002] A bearing is an important component in contemporary mechanical equipment. Its main function is to support a mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotational accuracy. After the bearing is produced, according to different usage scenarios, such as when the bearing needs to be used as a driven wheel in applications such as electric windows, a rubber coating process needs to be carried out on the outer surface of the bearing, so that the outer surface of the rubber-coated bearing has a greater friction force and better wear resistance. After the bearing undergoes the rubber coating process, the rubber on its outer surface is uneven and irregular. At this time, a turning process still needs to be carried out on the outer surface. In the prior art, when turning, each device can only turn 1 bearing each time, and its processing efficiency is extremely low. Content of the Utility Model

[0003] The utility model aims to at least solve one of the technical problems existing in the prior art. For this reason, the utility model provides a double-station turning mechanism for the surface of a rubber-coated pulley of a bearing, which has a simple structure and can improve the turning efficiency of the bearing.

[0004] To achieve the above object, the utility model provides the following technical solution:

[0005] A double-station turning mechanism for the surface of a rubber-coated pulley of a bearing, comprising a machine table, a two-way ejector rod module arranged in the middle of the machine table, two bearing installation rotating rods arranged on both sides of the two-way ejector rod module, a rotation driver for driving the two bearing installation rotating rods to rotate, a feeding module arranged in front of the bearing installation rotating rods, a bearing grasping manipulator arranged between the bearing installation rotating rods and the corresponding feeding modules, and a turning tool module arranged at the rear of the two-way ejector rod module. The turning tool module includes tools arranged corresponding to and perpendicular to the two bearing installation rotating rods one by one. The two-way ejector rod module includes two ejector rods arranged corresponding to and coaxially with the bearing installation rotating rods one by one.

[0006] In the above solution, the feeding module is used to convey the bearing workpieces to be turned. The bearing workpieces on the feeding module are grabbed by a bearing gripping manipulator and installed on the bearing installation rotating rod located at the rear of the feeding module. The bearing installation rotating rod can rotate. The bidirectional ejector rod module can drive two ejector rods to extend and respectively press against the bearing workpieces on the two bearing installation rotating rods, so that the bearing workpieces are fixed between the bearing installation rotating rod and the ejector rods. The rotation driver is fixedly connected to the bearing installation rotating rod and can drive the bearing installation rotating rod to rotate. In addition, when the bearing installation rotating rod rotates, it can drive the bearing workpiece to rotate, and the tool of the turning tool module turns the rotating bearing workpiece. The rotation driver can be a rotating motor or a driven driving component driven by a motor, which provides power for the bearing installation rotating rod and drives the bearing installation rotating rod to rotate.

[0007] In the present utility model, it can support two bearing workpieces to be turned simultaneously, thereby improving the turning efficiency.

[0008] In an embodiment, the rotation driver is located outside the corresponding bearing installation rotating rod, and a limit stop block is provided on one side of the bearing installation rotating rod close to the rotation driver.

[0009] In the above solution, the limit stop block is used to provide a limit for the bearing workpiece after the bearing workpiece is installed on the bearing installation rotating rod. In addition, the position directly opposite to the tool is the limit stop block. That is to say, the bearing workpiece is blocked at the limit stop block and is turned by the tool at this position during the subsequent turning process.

[0010] In an embodiment, a blanking module is provided on the rotation driver. The blanking module includes a blanking plate and a first driver for driving the blanking plate to move along the length direction of the bearing installation rotating rod. The output end of the first driver and the blanking plate are connected by a connecting rod. A through hole adapted to the bearing installation rotating rod is provided on the blanking plate, and the bearing installation rotating rod passes through the through hole.

[0011] In the above solution, the inner diameter of the through hole is smaller than the outer diameter of the bearing workpiece and larger than the outer diameter of the bearing installation rotating rod. It penetrates into the bearing installation rotating rod. When the bearing workpiece is turned, the first driver is started to make the blanking plate move towards the bidirectional ejector rod module, and the blanking plate peels the bearing workpiece off the bearing installation rotating rod to realize the blanking of the bearing workpiece. The first driver can be a cylinder.

[0012] In one embodiment, the bidirectional ejector rod module further includes a second driver, a connecting block, a first driving wheel, and a support base. Two second driver output rods are telescopically arranged at two output ends of the second driver. One end of the connecting block is fixedly connected to the second driver output rod, and the other end of the connecting block is rotatably connected to the ejector rod. The ejector rod passes through the first driving wheel and is key-connected to the first driving wheel (18).

[0013] In the above solution, the second driver can drive the two second driver output rods to perform telescopic motion. One end of the connecting block is fixedly connected to the second driver output rod, and a bearing is installed inside the other end of the connecting block. The outer circle of the bearing is fixedly connected to the inner wall of the connecting block, and the inner circle of the bearing is fixedly connected to one end of the ejector rod. When the second driver output rod performs telescopic motion, it can drive the ejector rod to perform telescopic motion at the same time. When the first driving wheel rotates, it can drive the ejector rod to rotate synchronously. When the second driver output rod extends, the ejector rod extends synchronously by a certain distance and then the ejector rod abuts and presses the bearing workpiece tightly on the bearing installation rotating rod.

[0014] In one embodiment, a first driving wheel hole is formed in the side wall of the first driving wheel. A sliding groove of the ejector rod is arranged in the middle of the ejector rod. A shaft hole is arranged on one side of the ejector rod close to the bearing installation rotating rod. The ejector rod can perform telescopic motion along with the second driver while rotating synchronously with the first driving wheel.

[0015] In the above solution, the first driving wheel is fixedly mounted on the support base. The support base is connected to the first driving wheel through a bearing. The first driving wheel hole can be a threaded hole. A screw is fixed in the first driving wheel hole and extends into the sliding groove of the ejector rod. When the first driving wheel rotates under external drive, the ejector rod can be driven to rotate synchronously by the screw fixed in the first driving wheel hole. When the second driver drives the second driver output rod to perform telescopic motion, it drives the ejector rod to perform telescopic motion. At this time, the screw slides in the sliding groove of the ejector rod, so that the ejector rod can rotate and telescopic.

[0016] In one embodiment, the second driver is a cylinder with two output ends.

[0017] In the above solution, the cylinder has two output ends.

[0018] In one embodiment, the second driver is two single-output-end cylinders, and each of the two single-output-end cylinders is cooperatively connected to an ejector rod.

[0019] In the above solution, both of the two cylinders are conventional unidirectional cylinders, and the two cylinders can be installed by being spliced front to back, or left to right, or up and down.

[0020] In one embodiment, the feeding module includes a vibrating feeder, the vibrating feeder includes a feeding track, and the bearing gripping manipulator grips the bearing workpiece at the end of the feeding track to transfer and fit the bearing workpiece onto the bearing mounting rotating rod.

[0021] In the above solution, the bearing gripping manipulator can be an automated gripping device driven by a cylinder.

[0022] In one embodiment, the turning tool module includes a tool rest, the tool rest can move in the front-back direction of the machine table, and the two tools are both mounted on the tool rest.

[0023] In the above solution, the tool rest can be driven to move back and forth by a driver, thereby realizing the function of the tool advancing and retracting during the conventional turning process. Generally, a linear module or a lead screw transmission module can be designed on the machine table to realize the front-back movement of the tool rest.

[0024] In one embodiment, a transmission rod is installed at the bottom of the machine table. A second driving wheel is provided at one end of the rotating driver away from the bearing mounting rotating rod. The transmission rod is fixedly provided with a transmission wheel set adapted to the first driving wheel and the second driving wheel. The transmission wheel set is connected to the adapted first driving wheel and second driving wheel by a belt or a chain to realize the synchronous rotation of the rotating bearing mounting rotating rod and the ejector rod.

[0025] In the above solution, by setting the transmission rod, only one driving motor is required for the entire device to transmit the rotation to the interconnected components. At the same time, the transmission wheel set is connected to the adapted first driving wheel and second driving wheel by a belt or a chain. When turning the bearing workpiece, the bearing mounting rod and the ejector rod rotate synchronously and in the same direction, thereby driving the bearing workpiece to rotate synchronously and in the same direction, so that the two side surfaces of the bearing workpiece will not be scratched, improving the qualification rate.

[0039] Specifically, the feeding module is used to convey the bearing workpieces to be turned. The bearing workpieces on the feeding module are grasped by the bearing grasping manipulator and installed on the bearing installation rotating rod 3 located at the rear of the feeding module. The bearing installation rotating rod 3 can rotate. The two-way ejector rod module 2 can drive the two ejector rods 6 to extend and respectively press against the bearing workpieces on the two bearing installation rotating rods 3, so that the bearing workpieces are fixed between the bearing installation rotating rod 3 and the ejector rod 6. The rotation driver 7 is fixedly connected to the bearing installation rotating rod 3 and can drive the bearing installation rotating rod 3 to rotate. In addition, when the bearing installation rotating rod 3 rotates, it can drive the bearing workpiece to rotate, and the tool of the turning tool module 4 turns the rotating bearing workpiece. The rotation driver 7 can be a rotating motor or a driven driving component driven by a motor, which provides power for the bearing installation rotating rod 3 and drives the bearing installation rotating rod 3 to rotate.

[0040] As Figures 1 - 5 shown, in some specific embodiments of the present utility model, the rotation driver 7 is located outside the corresponding bearing installation rotating rod 3, and a limit stop 8 is arranged on the side of the bearing installation rotating rod 3 close to the rotation driver 7.

[0041] Specifically, the limit stop 8 is used to provide a limit for the bearing workpiece after the bearing workpiece is installed on the bearing installation rotating rod 3. In addition, the position directly opposite to the tool 5 is the position of the limit stop 8. That is to say, the bearing workpiece is blocked at the limit stop 8 and is turned by the tool at this position during the subsequent turning process.

[0042] As Figures 1 - 5As shown, in some specific embodiments of the present utility model, a blanking module is provided on the rotation driver 7. The blanking module includes a blanking plate 9 and a first driver 10 for driving the blanking plate 9 to move along the length direction of the bearing-mounted rotating rod 3. The output end of the first driver 10 and the blanking plate 9 are connected by a connecting rod 11. A through hole 12 adapted to the bearing-mounted rotating rod 3 is provided on the blanking plate 9, and the bearing-mounted rotating rod 3 passes through the through hole 12.

[0043] Specifically, the inner diameter of the through hole 12 is smaller than the outer diameter of the bearing workpiece and larger than the outer diameter of the bearing-mounted rotating rod 3. It penetrates into the bearing-mounted rotating rod 3. After the bearing workpiece is turned, the first driver 10 is started to move the blanking plate 9 towards the direction of the double-ended ejector module 2, and the blanking plate 9 peels the bearing workpiece off the bearing-mounted rotating rod 3 to realize the blanking of the bearing workpiece; the first driver 10 can be a cylinder.

[0044] As Figures 1 - 5 As shown, in some specific embodiments of the present utility model, the double-ended ejector module 2 further includes a second driver 13, a connecting block 26, a first driving wheel 18 and a support seat 17. Two second driver output rods 13a are telescopically provided at both output ends of the second driver 13. One end of the connecting block 26 is fixedly connected to the second driver output rod 13a, and the other end of the connecting block 26 is rotatably connected to the ejector rod 6. The ejector rod 6 passes through the first driving wheel 18 and is key-connected to the first driving wheel 18.

[0045] Specifically, the second driver 13 can drive the two second driver output rods 13a to perform telescopic movements. One end of the connecting block 26 is fixedly connected to the second driver output rod 13a. A bearing is installed inside the other end of the connecting block 26. The outer circle of the bearing is fixedly connected to the inner wall of the connecting block 26, and the inner circle of the bearing is fixedly connected to one end of the ejector rod 6. When the second driver output rod 13a performs telescopic movements, it can drive the ejector rod 6 to perform telescopic movements at the same time. When the first driving wheel 18 rotates, it can drive the ejector rod 6 to rotate synchronously. When the second driver output rod 13a extends, the ejector rod 6 extends a certain distance synchronously and then the ejector rod abuts and presses the bearing workpiece against the bearing-mounted rotating rod.

[0046] As Figures 1 - 5 As shown, in some specific embodiments of the present utility model, a first driving wheel hole 18a is provided on the side wall of the first driving wheel 18, a ejector rod sliding groove 6a is provided in the middle of the ejector rod 6, and a shaft hole 14 is provided on the side of the ejector rod 6 close to the bearing-mounted rotating rod 3. The ejector rod 6 can move telescopically with the second driver 13 while rotating synchronously with the first driving wheel 18.

[0047] Specifically, the first driving wheel 18 is fixedly mounted on the support base 17. The support base 17 is connected to the first driving wheel 18 through a bearing. The first driving wheel hole 18a can be a threaded hole. A screw is fixed in the first driving wheel hole 18a and extends into the ejector rod sliding groove 6a. When the first driving wheel 18 rotates under external drive, the ejector rod 6 can be driven to rotate synchronously by the screw fixed in the first driving wheel hole 18a. When the second driver 13 drives the second driver output rod 13a to extend and retract, the ejector rod 6 is driven to extend and retract. At this time, the screw slides in the ejector rod sliding groove 6a, so that the ejector rod 6 can rotate and extend and retract.

[0048] As Figures 1 - 5 shown, in some specific embodiments of the present invention, the second driver 13 is a cylinder with two output ends.

[0049] As Figures 1 - 5 shown, in some specific embodiments of the present invention, the feeding module includes a vibrating feeder. The vibrating feeder includes a feeding track 15. The bearing grasping manipulator grasps the bearing workpiece at the end of the feeding track 15 to transfer and fit the bearing workpiece onto the bearing installation rotating rod 3.

[0050] Specifically, the bearing grasping manipulator can be an automated grasping device driven by a cylinder. The bearing workpiece to be processed is transported to the feeding track 15 after passing through the vibrating feeder and is conveyed to the end of the feeding track 15. The bearing grasping manipulator grasps the bearing workpiece at the end of the feeding track 15 and inserts it into the bearing installation rotating rod 3, facilitating the ejector rod 6 to abut the bearing workpiece against the limit stop 8.

[0051] As Figures 1 - 5 shown, in some specific embodiments of the present invention, the turning tool module 4 includes a tool rest 16. The tool rest 16 can move along the front-back direction of the machine table 1. Two tools 5 are both installed on the tool rest 16.

[0052] Specifically, the tool rest 16 can be driven to move back and forth by a driver, thereby realizing the function of the tool advancing and retracting during a conventional turning process. Generally, a linear module or a lead screw transmission module can be designed on the machine table to realize the back-and-forth movement of the tool rest.

[0053] As Figures 1 - 5 shown, in some specific embodiments of the present invention, a transmission rod 19 is installed at the bottom of the machine table 1. A second driving wheel 21 is provided at one end of the rotating driver 7 away from the bearing installation rotating rod 3. A transmission wheel set 20 adapted to the first driving wheel 18 and the second driving wheel 21 is fixedly provided on the transmission rod 19. The transmission wheel set 20 is connected to the adapted first driving wheel 18 and second driving wheel 21 through a belt or a chain to realize the synchronous rotation of the rotating bearing installation rotating rod 3 and the ejector rod 6.

[0054] Specifically, by setting the transmission rod 19, only one driving motor is required for the entire device to transmit rotation to each interconnected component. At the same time, the transmission pulley set 20 is connected to the adapted first driving pulley 18 and second driving pulley 21 by a belt or a chain. When only one of the two rotation drivers provided on the machine table 1 is an active driving motor, the motor rotates to drive the bearing mounting rotating rod 3 and the second driving pulley 21 to rotate, thereby driving the transmission rod 19 to rotate, and then driving the first driving pulley 18 to rotate. When the tool 5 is turning the bearing workpiece, the bearing mounting rod 3 and the ejector rod 6 rotate synchronously and in the same direction, thereby driving the bearing workpiece to rotate synchronously and in the same direction, so that the two side surfaces of the bearing workpiece will not be scratched, improving the qualification rate. At the same time, the motor can also directly drive the transmission rod 19 to rotate, and then achieve the same technical effect through the first driving pulley 18 and the second driving pulley 21. Therefore, as long as the active driving motor directly drives the transmission rod 19, any group of first driving rods 18, or any group of second driving rods 21, the same technical effect can be achieved.

[0055] In another specific embodiment provided by the present invention, refer to Figure 6 As shown, a rotating disk 22 driven by a motor is provided in the second driver 13. A sliding groove 23 is formed on the surface of the rotating disk 22 and is symmetrically distributed along the axis. One end of each of the two second driver output rods 13a is fixedly connected to a connecting rod 24. The two connecting rods 24 are respectively inserted into and slidably connected in the sliding groove 23. The other end of the second driver output rod 13a is connected to a connecting block 26. When the rotating disk 22 rotates clockwise, at this time, the rotating disk 22 drives the sliding groove 23 to rotate clockwise, thereby driving the two second driver output rods 13a to move inward, so as to achieve the effect of retracting the second driver output rods 13a. When the rotating disk rotates counterclockwise, it drives the two second driver output rods 13a to move outward, so as to achieve the effect of extending the second driver output rods 13a.

[0056] In another specific embodiment provided by the present invention, refer to Figure 7 As shown, the structure of the second driver 13 provided in this embodiment is two single-output oil cylinders. Both oil cylinders are conventional one-way oil cylinders. The two oil cylinders can be installed by splicing front and back, or left and right, or up and down. The output ends of the oil cylinders are respectively located on both sides. The output ends of the two oil cylinders are the second driver output rods 13a of the first embodiment.

[0057] The working principle of the present utility model is as follows: 1. Feeding: When the bearing workpiece to be processed is conveyed to the feeding module, the bearing grasping manipulator clamps the bearing workpiece and inserts it into the bearing installation rotating rod 3. 2. Clamping: Control the double-ended ejector rod module 2 to work, usually hydraulically controlled. At this time, the two ejector rods 6 move linearly in two directions respectively, and then the ejector rods 6 can abut and fix the bearing workpiece. 3. Turning: Control the rotation driver 7 to drive the bearing installation rotating rod 3 to rotate, and then the fixed bearing workpiece also rotates synchronously. Then control the tool rest 16 to move towards the bearing installation rotating rod 3. The tool rest 16 is provided with two cutting tools 5, so as to realize the turning of the workpiece. Unloading: After processing, the tool rest 16 moves in the opposite direction away from the bearing workpiece. At this time, control the unloading plate 9 to push the bearing workpiece out and slide it into the preset workpiece collection tray.
