Description

Technical Field

[0001] This invention belongs to the field of bearing testing technology, and relates to an instrument for aligning the inner and outer rings of a third-generation wheel hub bearing. More specifically, it relates to an instrument for locating the inner ring of a third-generation wheel hub bearing and for locating the relative position of the inner and outer rings. Background Technology

[0002] Current bearing testing instruments can only perform automatic vibration testing on first- and second-generation wheel hub bearings. For third-generation wheel hub bearings, the current method involves manually placing the bearing on a simple device, locating the inner ring, and then manually rotating the outer flange to locate the outer ring. Existing technology cannot achieve automatic loading, unloading, and testing of third-generation wheel hub bearings. This is mainly due to the irregular shapes of the inner and outer flanges, the varying number of bolts on the bearing itself, and other factors that make alignment and positioning difficult. Therefore, the lack of automatic alignment equipment for third-generation wheel hub bearings makes automatic vibration testing difficult. Summary of the Invention

[0003] The purpose of this invention is to develop a third-generation wheel hub bearing alignment instrument for automatic alignment and positioning of third-generation wheel hub bearings.

[0004] The technical solution of the present invention:

[0005] A third-generation wheel hub bearing alignment instrument includes a conveying device, an inner ring positioning device, and an outer ring positioning device, all of which are mounted on a bracket.

[0006] The inner ring positioning device is located at the end of the conveying device and includes a positioning tray mounted on a bracket. The positioning tray is provided with a limiting channel to accommodate at least two bolts from the wheel hub bearing to enter and slide along the limiting channel, thereby achieving inner ring positioning.

[0007] The outer ring positioning device includes a toggle mechanism, a lateral movement mechanism, a vertical movement mechanism, a power mechanism, and an outer ring positioning bracket. The outer ring positioning bracket is fixed on a support, and the lateral movement mechanism and the vertical movement mechanism are fixed to the outer ring positioning bracket. The lateral movement mechanism drives the toggle mechanism to move horizontally, pushing the bolts of the wheel hub bearing into the inner ring positioning device. The vertical movement mechanism drives the power mechanism to move up and down, driving the outer ring of the wheel hub bearing to rotate and achieve outer ring positioning.

[0008] The third-generation wheel hub bearing alignment instrument of the present invention employs an inner ring positioning device with a limiting channel, in conjunction with a toggle mechanism in an outer ring positioning device. When the third-generation wheel hub bearing is transported to a preset position by a conveying device, at least two bolts of the third-generation wheel hub bearing enter the limiting channel under the push of the toggle mechanism. As the bolts slide along the limiting channel, they are restricted within the limiting channel, thus completing the positioning of at least two bolts. At this time, the other bolts are also positioned accordingly, thereby achieving inner ring positioning.

[0009] As a preferred embodiment, any two bolts of the hub bearing can slide simultaneously along both sides of the limiting channel, at which point the limiting channel can radially limit the two bolts; the width of the limiting channel is adapted to the diameter of the bolts.

[0010] As another preferred option, any two bolts of the hub bearing slide along one side of the limiting channel, and another one or two bolts slide along the other side of the limiting channel. At this time, the limiting channel simultaneously forms a radial limit on three or more bolts. The width of the limiting channel is determined according to the shortest distance between the bolts that are in contact on both sides.

[0011] The limiting channel can be of any shape, such as a straight channel or a curved channel. When the limiting channel is a straight channel, the straight line containing the centers of the two bolts that slide along the same side of the limiting channel is X1, and X1 is parallel to the limiting channel.

[0012] Preferably, the positioning tray is equipped with an inner guide plate and an outer guide plate, and a limiting channel is formed between the adjacent sides of the inner guide plate and the outer guide plate.

[0013] Furthermore, the positioning tray may also be equipped with raised blocks for positioning the wheel hub bearing. When the bolts of the wheel hub bearing are radially limited by the limiting channel, they can only be displaced in the channel direction. At this time, the wheel hub bearing can be positioned by the raised blocks in its sliding direction.

[0014] Preferably, the entrance end of the limiting channel is provided with a guide section for guiding the bolt of the wheel hub bearing into the channel. A rotating body is installed on the edge of the guide surface of the guide section, and the edge of the rotating body protrudes from the edge of the guide surface. By setting the rotating body, when the bolt of the wheel hub bearing gets stuck when it enters, the bolt can smoothly enter the limiting channel by relying on the rotation of the rotating body.

[0015] Preferably, the outer ring positioning device is installed at the end of the conveying device, and the moving direction of the actuating mechanism is perpendicular to the conveying direction of the wheel hub bearing.

[0016] As a preferred embodiment, the outer ring positioning device also includes a guide frame, which is fixed to the outer ring positioning bracket via a slide rail. One end of the guide frame is equipped with a toggle mechanism, and the other end is fixedly connected to a lateral moving mechanism. The lateral moving mechanism drives the toggle mechanism to extend or retract via the guide frame. The vertical moving mechanism is installed on the guide frame and is fixedly connected to a power mechanism, which is used to drive the outer ring of the wheel hub bearing to rotate.

[0017] As another preferred embodiment, the third-generation wheel hub bearing alignment instrument of the present invention further includes a positioning sensor mounted on the conveying device, a positioning sensor mounted on the inner ring positioning device, and / or an outer ring flange positioning sensor mounted on the lateral movement mechanism or power mechanism; the positioning sensor is connected to the control system of the wheel hub bearing vibration detector to detect whether the conveying position of the wheel hub bearing has reached the preset position; the positioning sensor is connected to the control system of the wheel hub bearing vibration detector to detect whether the inner ring of the wheel hub bearing is in position; the outer ring flange positioning sensor is connected to the control system of the wheel hub bearing vibration detector to detect whether the outer ring flange of the wheel hub bearing is in position.

[0018] In the third-generation wheel hub bearing alignment instrument of the present invention, the lateral movement mechanism can be a lateral movement cylinder; the vertical movement mechanism can be a vertical movement cylinder; the power mechanism can be a servo motor; and the actuation mechanism can be a lever or a robotic arm.

[0019] The beneficial effects of this invention are as follows: This invention uses an external conveying device or a robotic arm to transfer the third-generation wheel hub bearing from the previous workstation to the conveying device of the alignment instrument; the inner ring positioning device enables the bolts of the bearing inner ring to slide in a specified direction, and the inner ring cannot rotate; the outer ring positioning device first helps to position the inner ring of the wheel hub bearing, and then, through the coordinated action of the vertical moving mechanism and the power mechanism in the outer ring positioning device, the relative position of the outer ring and the inner ring of the wheel hub bearing is determined, and the rotation direction of the outer ring flange is fixed; the wheel hub bearing is automatically positioned before inspection, achieving the expected alignment effect and preparing for automatic bearing inspection.

Detailed Implementation

[0033] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and technical solutions.

[0034] This invention relates to a third-generation wheel hub bearing alignment instrument, used to locate the inner ring flange bolts and the outer ring flange of the bearing before testing. Before testing, the inner and outer rings of the bearing are positioned to ensure that the inner ring flange bolts are at a fixed angle. Simultaneously, the outer ring flange is positioned to facilitate axial force loading onto the outer ring flange.

[0035] like Figure 1-7 The present invention provides a third-generation wheel hub bearing alignment instrument, comprising a conveying device 1, an inner ring positioning device 2, and an outer ring positioning device 3, all of which are mounted on a bracket 1.4.

[0036] The inner ring positioning device 2 is installed at the end of the conveying direction of the conveying device 1, and the two are on the same horizontal line. The outer ring positioning device 3 is installed at the end of the conveying device 1 and is perpendicular to the plane where the conveying device 1 and the inner ring positioning device 2 are located.

[0037] The conveying device 1 is used to transport the third-generation wheel hub bearing to be tested to the front end of the inner ring positioning device 2. The conveying device 1 includes a conveyor belt 1.1, on which the bolts of the wheel hub bearing are placed for automatic feeding. Guard plates 1.2 can be installed on both sides of the conveyor belt 1.1, serving to guide and prevent the wheel hub bearing from falling off during conveying. A position sensor 1.3 can also be installed on the conveying device 1. The position sensor 1.3 is installed at the front end of the inner ring positioning device 2 and is connected to an external control system (e.g., the control system of a wheel hub bearing vibration detector) to monitor whether the wheel hub bearing has reached the preset conveying position.

[0038] The inner ring positioning device 2 is used to position the inner ring of the third-generation wheel hub bearing to be tested. The inner ring positioning device 2 includes a positioning tray 2.3 mounted on the bracket 1.4. The positioning tray 2.3 is provided with a limiting channel 2.6. The limiting channel 2.6 can accommodate at least two bolts in the wheel hub bearing and radially limit the bolts, so that the bolts can only slide along the limiting channel 2.6 and cannot produce displacement in other directions. Since the movement path of the bolts is restricted in the limiting channel 2.6, the positioning of at least two bolts can be completed. At this time, the other bolts are also positioned accordingly, thereby realizing the positioning of the inner ring.

[0039] The positioning method for the inner ring of the third-generation wheel hub bearing in the limiting channel 2.6 can include two types:

[0040] In the first type, any two bolts of the wheel hub bearing slide simultaneously along both sides of the limiting channel 2.6. The width of the limiting channel 2.6 is adapted to the diameter of the bolts. In this case, the limiting channel 2.6 can radially limit the movement of the two bolts. Taking a wheel hub bearing with 5 bolts on the inner ring flange as an example... Figure 6 The first method of positioning the inner ring of the wheel hub bearing is shown, where two adjacent bolts are limited by the limiting channel 2.6, and the other three bolts are also positioned accordingly, thus positioning the inner ring.

[0041] In the second type, any two bolts of the wheel hub bearing slide along one side of the limiting channel 2.6, while another one or two bolts slide along the other side of the limiting channel 2.6. In this case, the limiting channel 2.6 can simultaneously provide radial limiting for three or more bolts, thus positioning the inner ring. For example... Figure 8Two bolts of the wheel hub bearing slide along one side of the limiting channel 2.6, and another bolt slides along the other side of the limiting channel 2.6. At this time, the limiting channel 2.6 radially limits three of the bolts. Let X1 be the line connecting the centers of the two bolts contacting the same side of the limiting channel 2.6, and A be the center point of the bolt contacting the other side. The width of the limiting channel 2.6 is determined based on the shortest distance from point A to line X1. For example... Figure 9 Two bolts of the hub bearing slide along one side of the limiting channel 2.6, and the other two bolts slide along the other side of the limiting channel 2.6. At this time, the limiting channel 2.6 radially limits the four bolts and positions the inner ring.

[0042] The inner ring positioning can be achieved by radially limiting at least two bolts of the wheel hub bearing through a limiting channel 2.6; other bolts of the wheel hub bearing may or may not be limited. Figure 10 After radially limiting two adjacent bolts of the wheel hub bearing, another limiting channel is set up to limit two of the remaining bolts; for example... Figure 11 Another limiting channel is set up to limit one of the remaining bolts; for example... Figure 12 Two additional limiting channels are provided to limit the remaining three bolts.

[0043] The limiting channel 2.6 can be of any shape, such as a straight channel or a curved channel; for example, when the limiting channel 2.6 is a straight channel, the straight line where the centers of the two bolts sliding along the same side of the limiting channel 2.6 are located is X1, which is parallel to the side of the limiting channel 2.6.

[0044] The limiting channel 2.6 can be formed on the positioning tray 2.3 in any form, such as by directly slotting the surface of the positioning tray 2.3 to form the limiting channel 2.6; it can also be formed by installing other components, such as... Figure 6 An inner guide plate 2.1 and an outer guide plate 2.2 can be installed on the positioning tray 2.3. A limiting channel 2.6 is formed between the two adjacent sides of the inner guide plate 2.1 and the outer guide plate 2.2.

[0045] The positioning tray 2.3 can also be equipped with a raised stop for positioning the hub bearing. The raised stop can be set at the end of the hub bearing in the direction of movement. When the bolt of the hub bearing is radially limited by the limiting channel 2.6, it can only be displaced in the direction of movement defined by the limiting channel 2.6. At this time, the hub bearing can be positioned by the upper limit of its direction of movement through the raised stop.

[0046] The limit channel 2.6 entrance end can also be equipped with a guide section to guide the wheel hub bearing bolts into the channel. A rotating body 2.5 is installed on the edge of the guide surface of the guide section, and the edge of the rotating body 2.5 protrudes from the edge of the guide surface. By setting the rotating body 2.5, when the wheel hub bearing bolts get stuck when entering, the bolts can smoothly enter the limit channel 2.6 by relying on the rotation of the rotating body.

[0047] A positioning sensor 2.4 can be installed on the inner ring positioning device 2. The positioning sensor 2.4 is connected to an external control system (e.g., connected to the control system of a wheel hub bearing vibration detector) to monitor whether the inner ring is in place by detecting the position of the wheel hub bearing bolts.

[0048] The inner ring positioning device 2 is installed at the end of the conveying direction of the conveying device 1. It can be set on the same plane as the conveying device 1 or slightly lower than the conveying device 1.

[0049] The outer ring positioning device 3 is used to assist in the positioning of the inner ring and to achieve the positioning of the outer ring.

[0050] The outer ring positioning device 3 includes a toggle mechanism 3.1, a horizontal movement mechanism 3.7, a vertical movement mechanism 3.4, a power mechanism 3.3, and an outer ring positioning bracket 3.6; the horizontal movement mechanism 3.7 can be a horizontal movement cylinder, the vertical movement mechanism 3.4 can be an up-down movement cylinder, the power mechanism 3.3 can be a servo motor, and the toggle mechanism 3.1 can be a toggle plate or a robotic arm.

[0051] The outer ring positioning bracket 3.6 is fixed on the bracket 1.4. The horizontal moving mechanism 3.7 and the vertical moving mechanism 3.4 are fixed to the outer ring positioning bracket 3.6. The horizontal moving mechanism 3.7 is connected to the actuating mechanism 3.1, which drives the actuating mechanism 3.1 to move horizontally and pushes the bolt of the wheel hub bearing into the limiting channel 2.6 of the inner ring positioning device 2. The vertical moving mechanism 3.4 is connected to the power mechanism 3.3, which can drive the power mechanism 3.3 to move up and down, drive the outer ring of the wheel hub bearing to rotate, and realize the outer ring positioning.

[0052] The outer ring positioning device 3 may also include a guide frame 3.2, which can be fixed to the outer ring positioning bracket 3.6 via a slide rail. One end of the guide frame 3.2 is equipped with a toggle mechanism 3.1, and the other end is fixedly connected to a lateral moving mechanism 3.7. The lateral moving mechanism 3.7 drives the toggle mechanism 3.1 to extend or retract through the guide frame 3.2. The vertical moving mechanism 3.4 may also be installed on the guide frame 3.2, and the vertical moving mechanism 3.4 is fixedly connected to a power mechanism 3.3. The power mechanism 3.3 drives the outer ring of the wheel hub bearing to rotate and reach its destination.

[0053] An outer ring flange positioning sensor 3.5 may be installed on the lateral movement mechanism 3.7 or the power mechanism 3.3 of the outer ring positioning device 3; the outer ring flange positioning sensor 3.5 is connected to an external control system (e.g., connected to the control system of the wheel hub bearing vibration detector) to monitor whether the outer ring flange of the wheel hub bearing is in place.

[0054] The lateral movement mechanism 3.7, the vertical movement mechanism 3.4, and the power mechanism 3.3 are also connected to an external control system (such as the control system of the wheel hub bearing vibration detector).

[0055] The third-generation wheel hub bearing alignment instrument of the present invention employs an inner ring positioning device 2 with a limiting channel 2.6, in conjunction with an actuating mechanism 3.1 in an outer ring positioning device 3. When the third-generation wheel hub bearing is transported to a preset position by the conveying device 1, at least two bolts of the third-generation wheel hub bearing enter the limiting channel 2.6 under the push of the actuating mechanism 3.1. During the sliding process of the bolts along the limiting channel 2.6, they are restricted within the limiting channel 2.6, completing the positioning of at least two bolts. At this time, the other bolts are also positioned accordingly, thereby realizing the inner ring positioning. After the inner ring is positioned, the vertical moving mechanism 3.4 and the power mechanism 3.3 in the outer ring positioning device 3 cooperate to realize the positioning of the outer ring flange relative to the inner ring.

[0056] Example

[0057] like Figures 1-5 As shown, this invention discloses a third-generation wheel hub bearing alignment instrument, comprising a conveying device 1, an inner ring positioning device 2, and an outer ring positioning device 3. A bracket 1.4 supports the conveying device 1, the inner ring positioning device 2, and the outer ring positioning device 3. The inner ring positioning device 2 is installed at the end of the conveying device 1, and the two are on the same horizontal line; the outer ring positioning device 3 is also installed at the end of the conveying device 1, and is perpendicular to the plane containing the conveying device 1 and the inner ring positioning device 2. Sensors are respectively installed on the conveying device 1, the inner ring positioning device 2, and the outer ring positioning device 3, and the sensors are respectively connected to the control PLC of the fully automatic wheel hub bearing vibration detection instrument.

[0058] like Figure 5 As shown, the conveying device 1 includes a conveyor belt 1.1, guard plates 1.2, and a positioning sensor 1.3. The conveyor belt 1.1 is used to transport the third-generation wheel hub bearing, and guard plates 1.2 are installed on both sides of it. The guard plates 1.2 serve to prevent the bearing from falling and to guide it. The positioning sensor 1.3 is installed at the front end of the inner ring positioning device 2. The bolts of the third-generation wheel hub bearing to be tested are transported by the conveyor device 1 and triggered by the positioning sensor 1.3 after reaching the position. When the positioning sensor 1.3 detects that the third-generation wheel hub bearing to be tested has reached the position, the conveyor belt 1.1 stops transporting, and the outer ring positioning device 3 extends the bearing pusher plate 3.1 to push the third-generation wheel hub bearing to be tested into the inner ring positioning device 2 and push it to the front end of the inner ring positioning device 2.

[0059] like Figure 6 As shown, the structure of the inner ring positioning device 2 includes: the positioning tray 2.3, which is mounted on the bracket 1.4 to support and guide the wheel hub bearing; the inner guide plate 2.1, which is mounted on the positioning tray 2.3, and serves to guide the inner ring bolt of the bearing; the outer guide plate 2.2, which is mounted on the positioning tray 2.3, and serves to guide the inner ring bolt and block the wheel hub bearing; the positioning sensor 2.4, which is mounted on the positioning tray 2.1, receives a signal when the inner ring bolt of the wheel hub bearing is pushed into place, and starts the outer ring positioning. After the outer ring is positioned, the outer ring positioning device 3 retracts.

[0060] The inner ring positioning device 2 includes an inner guide plate 2.1, an outer guide plate 2.2, a positioning tray 2.3, and a positioning sensor 2.4. The positioning tray 2.3 is mounted on the bracket 1.4. The inner guide plate 2.1 and the outer guide plate 2.2 are sequentially mounted on the positioning tray 2.3 according to the transmission direction of the bolts of the third-generation wheel hub bearing to be tested. A limiting channel 2.6 is formed between the right side of the inner guide plate 2.1 and the left side of the outer guide plate 2.2. The width of the channel is adapted to the bolt diameter of the third-generation wheel hub bearing to be tested, that is, it is larger than the bolt diameter of the wheel hub bearing and less than or equal to the bolt diameter plus the dimensional tolerance, which can just accommodate two bolts moving forward along both sides of the limiting channel 2.6. The inner guide plate 2.1 has a rounded pointed end, which can guide the bolts of the third-generation wheel hub bearing into the wheel hub bearing. A circular rotating body 2.5 is installed at the top pointed end. The edge of the circular rotating body 2.5 protrudes from the rounded pointed edge. If the bolts of the wheel hub bearing get stuck when entering, they can smoothly enter the limiting channel 2.6 with the rotation of the circular rotating body 2.5. The end of the positioning tray 2.3 is provided with a raised stop. When the bolt of the third-generation wheel hub bearing to be tested reaches the raised stop, the bolt of the third-generation wheel hub bearing to be tested stops moving forward. The positioning sensor 2.4 is mounted on the positioning tray 2.1. When the bolt of the third-generation wheel hub bearing to be tested is in place, the bolt triggers the positioning sensor 2.4. The positioning sensor 2.4 receives a signal, the bearing lever 3.1 stops moving, the vertical moving mechanism 3.4 extends, and the outer ring flange positioning begins. After the outer ring flange is positioned, the vertical moving mechanism 3.4 retracts, the outer ring positioning device 3 retracts the bearing lever 3.1, and the alignment and positioning of the wheel hub bearing is completed. At this time, the gripper of the bearing detection can grab the positioned wheel hub bearing for detection.

[0061] Figure 6 In the process, the width of the inner guide plate 2.1 is determined based on the bolt spacing of the third-generation wheel hub bearing to be tested: draw a straight line 1 through the center of two adjacent bolts on the third-generation wheel hub bearing to be tested, and then draw a straight line 2. The straight line 2 is parallel to the straight line 1 and passes through the other two bolts on the wheel hub bearing to be tested. The distance between the straight lines 1 and 2 should be minimized. The distance between the straight lines 1 and 2 minus the bolt diameter of the third-generation wheel hub bearing to be tested is the width of the inner guide plate 2.1.

[0062] like Figure 7As shown, the outer ring positioning device 3 includes a toggle mechanism 3.1, a guide frame 3.2, a power mechanism 3.3, a vertical moving mechanism 3.4, an outer ring flange positioning sensor 3.5, an outer ring positioning bracket 3.6, and a horizontal moving mechanism 3.7. The horizontal moving mechanism 3.7 uses a horizontal moving cylinder, the vertical moving mechanism 3.4 uses an up-and-down moving cylinder, the power mechanism 3.3 uses a servo motor, and the toggle mechanism 3.1 uses a toggle plate. The outer ring positioning bracket 3.6 is fixed on the bracket 1.4, and the guide frame 3.2 is fixed to the outer ring positioning bracket 3.6 via a slide rail, and the guide frame 3.2 moves on the slide rail; the lever plate is installed on the guide frame 3.2, and the width of the lever plate matches the third-generation wheel hub bearing to be tested, which is used to push the bolts of the wheel hub bearing into place; the guide frame 3.2 is connected to the lateral movement mechanism 3.7, which is fixed on the outer ring positioning bracket 3.6, and is used to drive the guide frame 3.2 to extend or retract laterally, and the lateral movement mechanism 3.7 is connected to the control PLC of the fully automatic wheel hub bearing vibration testing instrument; the guide frame 3.2 is also connected to the vertical movement mechanism 3.4, which supports the vertical movement mechanism 3.4 and drives the vertical movement mechanism 3.4 to move laterally with the extension and retraction of the lateral movement mechanism 3.7. The power mechanism 3.3 is mounted on the vertical moving mechanism 3.4. The vertical moving mechanism 3.4 drives the power mechanism 3.3 to move up and down. The power mechanism 3.3 is used to drive the outer ring of the wheel hub bearing to rotate. The vertical moving mechanism 3.4 and the power mechanism 3.3 are respectively connected to the control PLC of the fully automatic wheel hub bearing vibration detection instrument. The outer ring flange positioning sensor 3.5 is mounted on the power mechanism 3.3 to monitor whether the outer ring flange of the wheel hub bearing is in place. There are two outer ring flange positioning sensors 3.5, located on both sides of the power mechanism 3.3. The power mechanism 3.3 drives the outer ring of the wheel hub bearing to rotate. When both outer ring flange positioning sensors 3.5 detect the outer ring flange at the same time, it means that the outer ring flange is in place, and the power mechanism 3.3 stops rotating; otherwise, it is not in place, and the power mechanism 3.3 continues to drive the outer ring of the bearing to rotate until the outer ring flange is in place, at which point the power mechanism 3.3 stops rotating.

[0063] Specific implementation process:

[0064] The third-generation wheel hub bearing from the previous station is transferred to the conveying device 1 of the third-generation wheel hub bearing alignment instrument of this invention via an external conveying device or a robotic arm. The conveying device 1 transports the wheel hub bearing via a conveyor belt 1.1, with side guard plates 1.2 protecting the wheel hub bearing and a bracket 1.4 supporting the entire alignment instrument. When the third-generation wheel hub bearing to be tested is transported to the front of the inner ring positioning device 2, the positioning sensor 1.3 receives a signal, the conveyor belt 1.1 stops running, the push plate extends, and pushes the third-generation wheel hub bearing to be tested into the inner ring positioning device 2 and into position. The inner ring bolts of the third-generation wheel hub bearing to be tested are guided along the inner guide plate 2.1 and the outer guide plate 2.2, and are positioned at the limit of the positioning tray 2.3. Slide the guide plate on track 2.6 until the inner ring bolt is pushed into place. The positioning sensor 2.4 receives a signal, and the lever stops moving. The vertical moving mechanism 3.4 extends, and the power mechanism 3.3 drives the outer ring of the third-generation wheel hub bearing under test to rotate. The outer ring flange positioning sensor 3.5 monitors whether the outer ring flange of the wheel hub bearing is in place. If the outer ring flange is in place, the lateral moving mechanism 3.7 controls the guide frame 3.2 to drive the vertical moving mechanism 3.4 to retract. If the outer ring flange is not in place, the power mechanism 3.3 drives the outer ring of the wheel hub bearing to continue rotating until the outer ring flange is in place. The lateral moving mechanism 3.7 then controls the vertical moving mechanism 3.4 to retract. The bearing alignment and adjustment are complete.

[0065] The present invention provides a third-generation wheel hub bearing alignment instrument, which is a mechanism for aligning the position of the inner ring flange bolts and the position of the outer ring flange relative to the inner ring of the bearing. The limiting channel 2.6 of the inner ring positioning device 2 is used to position the bolts of the inner ring flange of the bearing, and the inner ring is fixed after positioning. The outer ring positioning device 3 is used to position the outer ring flange of the bearing. The positioning of the outer ring flange relative to the inner ring is achieved through the cooperation of the outer ring positioning sensor and the power mechanism 3.3.

[0066] Bearing alignment refers to the alignment and positioning of the inner ring flange bolts and the outer ring flange. This invention provides a third-generation wheel hub bearing alignment instrument. A conveying device 1 transports the wheel hub bearing from the previous station to the front end of the inner ring positioning device 2. The inner ring positioning device 2 ensures that the bolts on the inner ring of the bearing slide in a specified direction, and the inner ring cannot rotate. The outer ring positioning device 3 pushes the wheel hub bearing into position. Then, through the coordinated action of the vertical movement mechanism and the power mechanism, the relative position of the outer ring and inner ring of the wheel hub bearing is determined, and the rotation direction of the outer ring flange is fixed, thus achieving the alignment and positioning of the wheel hub bearing. Automatic positioning of the wheel hub bearing before inspection achieves the expected alignment effect, preparing for automatic bearing inspection.

[0067] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration.
