Description

Technical Field

[0001] This utility model relates to a drive device for measuring bearing discs, belonging to the field of bearing disc measurement technology. Background Technology

[0002] A brake is a component in a braking system used to generate braking force that impedes the movement or tendency of a vehicle to move. Currently, based on the different rotating elements, they can be divided into two main categories: drum brakes and disc brakes. In a disc brake, the rotating element in the friction pair is a disc-shaped brake disc with its end face as the working surface. The friction elements clamp the brake disc from both sides to generate braking force. A bearing disc is one type of brake disc.

[0003] The quality of a car's braking system is related to the personal safety of drivers and pedestrians. The car bearing disc is a key component related to the car's safety performance. Therefore, after the car bearing disc is manufactured, it is necessary to measure the end face runout and the thickness uniformity of the disc body.

[0004] Traditionally, bearing disc measurement involves manually placing the bearing disc on a support fixture, moving the fixture to the measurement position, and then manually rotating the bearing disc using a dial indicator (such as a micrometer). Bearing discs typically weigh over 20 kilograms, and the manual handling and rotation are labor-intensive. Improper operation can also affect measurement results, leading to low efficiency. Due to this inefficiency, most bearing discs are currently inspected by sampling, making it impossible to achieve 100% inspection and ensuring quality control.

[0005] To match the automated production of bearing discs and solve the aforementioned problems of existing manual measurement of bearing discs, research began on a bearing disc measuring instrument capable of automated measurement. To achieve automated measurement of bearing discs, the problem of rotating drive of bearing discs needs to be solved. Therefore, a drive device for measuring bearing discs is required. This drive device can rotate the bearing disc during measurement without interfering with the measurement. Utility Model Content

[0006] This invention addresses the shortcomings of existing technologies by providing a driving device for measuring bearing discs.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A driving device for measuring bearing discs includes a support plate, a driving roller disposed on the support plate, a rotation driving mechanism for driving the roller to rotate, and a position moving mechanism for driving the roller to move. The support plate is provided with a roller bracket, and the driving roller is rotatably disposed on the roller bracket. Under the action of the position moving mechanism and the rotation driving mechanism, the driving roller can act on the outer peripheral surface of the bearing disc and drive the bearing disc to rotate.

[0008] The beneficial effects of this utility model are as follows: The driving device uses a driving roller acting on the outer circle of the bearing disk to drive the bearing disk to rotate through friction. This is mainly because the bearing disk needs to be positioned through its inner hole and its runout and thickness uniformity needs to be measured by a measuring instrument acting on the end face of the bearing disk during automatic measurement. To avoid interference with the positioning and measurement of the bearing disk, the outer circle of the bearing disk is driven. Specifically, the driving roller is mounted on a roller bracket. When the position moving mechanism is activated, it can drive the driving roller to move towards the workpiece, so that the roller surface of the driving roller can contact the outer circumferential surface of the bearing disk. When the rotation driving mechanism is activated, the driving roller contacts the bearing disk and drives the bearing disk to rotate through friction, meeting the rotation requirements of the bearing disk and preparing for the automatic measurement of the bearing disk. This utility model has a simple structure, and the driving roller can act on the outer circumferential surface of the bearing disk to achieve stable rotational drive of the bearing disk, reducing the labor intensity of workers, improving the accuracy and efficiency of measurement, and providing strong support for the realization of automated measurement of bearing disks.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, it also includes a base, and an elastic clamping mechanism is provided between the support plate and the base. The position moving mechanism is used to drive the base to move horizontally.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the elastic clamping mechanism can avoid damage to the bearing disk and drive roller by the impact force generated when the drive roller contacts the workpiece. It can also ensure that the drive roller can always contact the outer peripheral surface of the bearing disk during the measurement process, ensuring stable rotation drive of the bearing disk during the measurement process.

[0012] Furthermore, the elastic clamping mechanism includes a buffer spring, a spring guide rod, and a spring limiting plate. The spring limiting plate is disposed on the base and has a plate hole. The rod end of the spring guide rod passes through the plate hole and connects to the support plate. The buffer spring is fitted onto the spring guide rod between the spring limiting plate and the support plate.

[0013] The beneficial effects of adopting the above-mentioned further solution are that, on the one hand, the buffer spring plays a buffering role when the drive roller contacts the outer circumferential surface of the workpiece bearing disk, absorbing part of the impact force and avoiding damage to the drive roller and bearing disk; on the other hand, the elasticity of the buffer spring also ensures that the drive roller is always in close contact with the outer circle of the bearing disk during driving, ensuring the driving force on the bearing disk.

[0014] Furthermore, it also includes a plate guiding mechanism for guiding the movement of the pallet, the plate guiding mechanism including a plate moving guide rail and a plate moving slider adapted to the plate moving guide rail, the plate moving guide rail being disposed on the base or the pallet, and the plate moving slider being disposed on the pallet or the base.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the plate guiding mechanism limits the movement trajectory of the pallet, reduces friction and resistance during the movement process, and enables the pallet to move along the plate moving guide rail during the movement relative to the base. This avoids possible deviation or shaking of the pallet during the movement process, thereby ensuring that the drive roller can accurately contact and drive the bearing disc, and improving the reliability and stability of the automatic measurement of the bearing disc.

[0016] Furthermore, the rotation drive mechanism includes a rotation motor for driving the drive roller to rotate, and the rotation motor is disposed on the support plate.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the rotation of the motor can drive the drive roller to rotate, and the drive roller drives the bearing disc to rotate through friction. The drive roller rotates smoothly, improving the reliability of the drive link in the automatic measurement process of the bearing disc. Furthermore, a rotational transmission mechanism is provided between the rotating motor and the driving roller. The rotational transmission mechanism includes a rotating driving wheel, a rotating driven wheel, and a rotating conveyor belt surrounding the rotating driving wheel and the rotating driven wheel. The rotating driving wheel is disposed on the output shaft of the rotating motor, and the rotating driven wheel is disposed on the axle of the driving roller.

[0018] The beneficial effects of adopting the above-mentioned further solution are that when the rotating motor is running, its output shaft drives the rotating drive wheel to rotate. Since the rotating conveyor belt is wrapped around the rotating drive wheel and the rotating driven wheel, the rotation of the rotating drive wheel is transmitted to the rotating driven wheel through the rotating conveyor belt, which in turn drives the rotating driven wheel set on the drive roller shaft to rotate, ultimately realizing the rotation of the drive roller. The rotating transmission mechanism can effectively realize the transmission of power and maintain a relatively stable transmission ratio during the transmission process, so that the drive roller can rotate according to the speed requirement, ensuring the stability and controllability of the bearing disc rotation speed. In addition, the addition of the rotating transmission mechanism can also reduce the space occupied in the height direction of the drive device, making the structure of the drive device more compact.

[0019] Furthermore, it also includes a drive base plate. The position moving mechanism includes a moving screw, a moving nut that cooperates with the moving screw, and a moving motor for driving the moving screw to rotate. The moving screw is rotatably mounted on the drive base plate, and the moving nut is connected to the base.

[0020] The beneficial effect of adopting the above-mentioned further solution is that when the moving motor is activated, it drives the moving screw to rotate. Since the moving nut is threadedly engaged with the moving screw, it will drive the moving nut to move linearly along the axial direction of the moving screw. The moving nut is connected to the base, which in turn drives the base to move on the drive base plate, thereby realizing the movement of the drive roller towards or away from the bearing plate.

[0021] Furthermore, a moving transmission mechanism is provided between the moving motor and the moving lead screw. The moving transmission mechanism includes a moving driving wheel, a moving driven wheel, and a moving conveyor belt surrounding the moving driving wheel and the moving driven wheel. The moving driving wheel is connected to the output shaft of the moving motor, and the moving driven wheel is disposed on the moving lead screw.

[0022] The beneficial effect of adopting the above-mentioned further solution is that after the moving motor starts, its output shaft drives the moving drive wheel to rotate. Since the moving conveyor belt wraps around the moving drive wheel and the moving driven wheel, the rotation of the moving drive wheel will drive the moving driven wheel to rotate through the moving conveyor belt. The moving driven wheel is mounted on the moving lead screw, thus driving the moving lead screw to rotate. The power transmission from the moving motor to the moving lead screw is realized through the moving transmission mechanism, ensuring the smooth operation of the position moving mechanism and guaranteeing the reliability of the entire drive device.

[0023] Furthermore, the drive base plate is also provided with a seat guide mechanism for guiding the movement of the base. The seat guide mechanism includes a seat moving guide rail and a seat moving slider adapted to the seat moving guide rail. The seat moving guide rail is disposed on the drive base plate, and the seat moving slider is disposed at the bottom of the base.

[0024] The beneficial effect of adopting the above-mentioned further solution is that the seat moving guide rail can provide guidance for the movement of the base, ensuring that the base can move along the predetermined trajectory, avoiding deviation or shaking of the base during movement, thereby improving the accuracy of bearing plate measurement. The cooperative use of the seat moving guide rail and the seat moving slider makes the movement of the base more stable and smooth, reducing friction and resistance during movement, and further improving the operational stability of the entire drive device.

[0025] Furthermore, the drive roller is made of polyurethane.

[0026] The beneficial effects of adopting the above-mentioned further solution are that the polyurethane material has good wear resistance, which enables the drive roller to maintain surface integrity and performance during long-term use, reducing drive instability caused by wear, thereby ensuring continuous measurement of bearing disc rotation. When the polyurethane drive roller contacts the bearing disc, it can provide a more uniform and stable driving force, avoiding measurement errors caused by the drive surface being too hard or too soft, which could affect the rotation of the bearing disc.

Detailed Implementation

[0028] The principles and features of this utility model are described below with reference to examples. The examples are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0029] like Figures 1-5 As shown, a driving device for measuring bearing discs includes a support plate 102, a driving roller 101 disposed on the support plate 102, a rotation driving mechanism for driving the roller 101 to rotate, and a position moving mechanism for driving the roller 101 to move. The support plate 102 is provided with a roller bracket 103, and the driving roller 101 is rotatably disposed on the roller bracket 103. Under the action of the position moving mechanism and the rotation driving mechanism, the driving roller 101 can act on the outer peripheral surface of the bearing disc and drive the bearing disc to rotate.

[0030] It also includes a base 104, and an elastic clamping mechanism is provided between the support plate 102 and the base 104. The position moving mechanism is used to drive the base 104 to move horizontally. The elastic clamping mechanism can absorb the impact force generated when the drive roller 101 contacts the workpiece, avoiding damage to the bearing disk and the drive roller 101. It can also ensure that the drive roller can always contact the outer peripheral surface of the bearing disk during the measurement process, ensuring stable rotation drive of the bearing disk during the measurement process.

[0031] The elastic clamping mechanism includes a buffer spring 105, a spring guide rod 106, and a spring limiting plate 107. The spring limiting plate 107 is disposed on the base 104 and has a plate hole. The rod end of the spring guide rod 106 passes through the plate hole and connects to the support plate 102. The buffer spring 105 is fitted onto the spring guide rod 106 between the spring limiting plate 107 and the support plate 102. The buffer spring 105 acts as a buffer when the drive roller 101 contacts the outer circumference of the workpiece bearing disk, absorbing part of the impact force and preventing damage to the drive roller 101 and the bearing disk. Furthermore, the elastic force of the buffer spring 105 ensures that the drive roller 101 remains in close contact with the outer circumference of the bearing disk during operation, guaranteeing the driving force on the bearing disk. The outer diameter of the rod head of the spring guide rod 106 is larger than the diameter of the plate hole.

[0032] The system also includes a plate guiding mechanism for guiding the movement of the pallet 102. The plate guiding mechanism includes a plate moving guide rail 108 and a plate moving slider 109 adapted to the plate moving guide rail 108. The plate moving guide rail 108 is disposed on the base 104 or the pallet 102, and the plate moving slider 109 is disposed on the pallet 102 or the base 104. The plate guiding mechanism limits the movement trajectory of the pallet 102, reducing friction and resistance during movement. This allows the pallet 102 to move along the plate moving guide rail 108 relative to the base 104, preventing possible offset or wobbling of the pallet 102 during movement. This ensures that the drive roller 101 accurately contacts and drives the bearing disc, improving the reliability and stability of the automatic measurement of the bearing disc.

[0033] The rotation drive mechanism includes a rotary motor 110 for driving the drive roller 101 to rotate, and the rotary motor 110 is mounted on the support plate 102. The rotary motor 110 is mounted on the support plate 102 via a motor mounting base 111. When the rotary motor 110 is activated, it drives the drive roller 101 to rotate. The drive roller 101 drives the bearing disc to rotate through friction. The rotation of the drive roller 101 is smooth, improving the reliability of the drive mechanism during the automatic measurement of the bearing disc. The rotary motor 110 may include a stepper motor and a reducer.

[0034] A rotational transmission mechanism is provided between the rotating motor 110 and the drive roller 101. The rotational transmission mechanism includes a rotating driving wheel 112, a rotating driven wheel 113, and a rotating conveyor belt surrounding the rotating driving wheel 112 and the rotating driven wheel 113. The rotating driving wheel 112 is disposed on the output shaft of the rotating motor 110, and the rotating driven wheel 113 is disposed on the axle of the drive roller 101. When the rotating motor 110 is running, its output shaft drives the rotating drive wheel 112 to rotate. Since the rotating conveyor belt is wrapped around the rotating drive wheel 112 and the rotating driven wheel 113, the rotation of the rotating drive wheel 112 is transmitted to the rotating driven wheel 113 through the rotating conveyor belt, which in turn drives the rotating driven wheel 113 set on the wheel axle of the drive roller 101 to rotate, ultimately realizing the rotation of the drive roller 101. The rotating transmission mechanism can effectively realize the transmission of power and maintain a relatively stable transmission ratio during the transmission process, so that the drive roller 101 can rotate according to the speed requirements, ensuring the stability and controllability of the bearing disc rotation speed. In addition, the addition of the rotating transmission mechanism can also reduce the space occupied in the height direction of the drive device, making the structure of the drive device more compact.

[0035] The system also includes a drive base plate 114. The position moving mechanism includes a movable lead screw 115, a movable nut 116 cooperating with the movable lead screw 115, and a movable motor 117 for driving the movable lead screw 115 to rotate. The movable lead screw 115 is rotatably mounted on the drive base plate 114, and the movable nut 116 is connected to the base 104. The movable nut 116 is connected to the base 104 through a lead screw nut seat. When the movable motor 117 is activated, it drives the movable lead screw 115 to rotate. Since the movable nut 116 is threadedly engaged with the movable lead screw 115, it drives the movable nut 116 to move linearly along the axial direction of the movable lead screw 115. The movable nut 116 is connected to the base 104, thereby causing the base 104 to move on the drive base plate 114, thus enabling the drive roller 101 to move towards or away from the bearing disc.

[0036] A moving transmission mechanism is provided between the moving motor 117 and the moving lead screw 115. The moving transmission mechanism includes a moving drive wheel 118, a moving driven wheel 119, and a moving conveyor belt surrounding the moving drive wheel 118 and the moving driven wheel 119. The moving drive wheel 118 is connected to the output shaft of the moving motor 117, and the moving driven wheel 119 is mounted on the moving lead screw 115. After the moving motor 117 starts, its output shaft drives the moving drive wheel 118 to rotate. Since the moving conveyor belt surrounds the moving drive wheel 118 and the moving driven wheel 119, the rotation of the moving drive wheel 118 drives the moving driven wheel 119 to rotate via the moving conveyor belt. The moving driven wheel 119, in turn, is mounted on the moving lead screw 115, thus driving the moving lead screw 115 to rotate. The moving transmission mechanism realizes the power transmission from the moving motor 117 to the moving lead screw 115, ensuring the smooth operation of the position moving mechanism and guaranteeing the reliability of the entire drive device.

[0037] The drive base plate 114 is also provided with a seat guide mechanism for guiding the movement of the base 104. The seat guide mechanism includes a seat moving guide rail 120 and a seat moving slider 121 adapted to the seat moving guide rail 120. The seat moving guide rail 120 is disposed on the drive base plate 114, and the seat moving slider 121 is disposed at the bottom of the base 104. The seat moving guide rail 120 can provide guidance for the movement of the base 104, ensuring that the base 104 can move along a predetermined trajectory, avoiding deviation or shaking of the base 104 during movement, thereby improving the accuracy of bearing plate measurement. The cooperative use of the seat moving guide rail 120 and the seat moving slider 121 makes the movement of the base 104 more stable and smooth, reducing friction and resistance during movement, and further improving the operational stability of the entire drive device.

[0038] The drive roller 101 is made of polyurethane. Polyurethane has excellent wear resistance, enabling the drive roller 101 to maintain surface integrity and performance during prolonged use, reducing drive instability caused by wear, and thus ensuring continuous measurement of the bearing disc's rotation. When in contact with the bearing disc, the polyurethane drive roller 101 provides a relatively uniform and stable driving force, avoiding measurement errors caused by a drive surface that is too hard or too soft, which could affect the bearing disc's rotation.

[0039] When the movable motor 117 is activated, the movable lead screw 115 rotates. The nut of the movable lead screw 115 moves linearly along its axial direction, driving the base 104 towards the measurement position of the bearing disc until the drive roller 101 contacts the outer circumference of the bearing disc. Then, the rotary motor 110 is activated, rotating the drive wheel 112 to transmit power to the driven wheel 113, causing the drive roller 101 to rotate. The drive roller 101 drives the bearing disc to rotate through friction, providing support for the measurement of the bearing disc. After the bearing disc measurement is completed, the rotary motor 110 stops, the movable motor 117 reverses its direction, the movable lead screw 115 rotates in the opposite direction, and the movable nut 116 drives the base 104 to move away from the bearing disc, avoiding interference with the bearing disc's discharge. This invention has a simple structure. The drive roller 101 acts on the outer circumference of the bearing disc to achieve stable rotational drive, reducing the labor intensity of workers, improving measurement accuracy and efficiency, and providing rotational drive for automated bearing disc measurement.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
