[0045] As a supplementary explanation of the background technology, the assembly of a spherical plain bearing and a product joint belongs to interference fit. Generally, after the spherical plain bearing is installed, the inner ring and outer ring of the bearing will be deformed due to force and other reasons, and the dimensions will become smaller accordingly, resulting in a smaller clearance between the inner and outer rings of the spherical plain bearing and even inability to rotate normally. Therefore, in order to solve this problem during the assembly stage, generally, a certain external force is applied to the inner and outer rings of the bearing and abrasive paste is used to appropriately grind the spherical plain bearing. The essence of the grinding process of the spherical plain bearing is to change the assembly clearance between the inner ring and the outer ring of the spherical plain bearing through an external force; during the grinding process, if the applied external force is too large or the grinding time is too long, the clearance between the inner ring and the outer ring of the bearing will not meet the requirements, which may cause the bearing to be scrapped and even affect the service life of the assembled product. It can be seen that insufficient grinding or exceeding the specified grinding amount will have a certain impact on the bearing and the assembled product.

[0046] To solve the technical problem of controlling the grinding amount of the bearing, an embodiment of this application provides a grinding device for a spherical plain bearing 24. See Figures 1 to 4As shown, it includes a grinding frame 1, a tensioning assembly, a power input assembly and a power output assembly. Among them, one side of the grinding frame 1 is a processing station, and a fixing assembly for clamping the joint bearing 24 is arranged on one side of the processing station. The power input assembly provides power input for grinding the joint bearing 24, the power output assembly is connected to the power output assembly, the tensioning assembly connects the joint bearing 24 and the power output assembly, and the power output assembly uses the power from one end of the power input assembly to make the joint bearing 24 complete an elliptical motion, so as to achieve the purpose of grinding the gap between the inner ring and the outer ring.

[0047] Specifically:

[0048] See also Figures 1 to 4 As shown, the fixing assembly includes a carrier and a clamping member, the carrier is used to fix the spherical bearing 24, and the clamping member is used to fix the carrier to the grinding frame 1. Specifically, the carrier includes a U-shaped mounting joint 6, the mounting joint 6 is fixed to the grinding frame 1 through the clamping member, the U-shaped opening of the mounting joint 6 faces the center of the grinding frame 1, and the inner side of the mounting joint 6 is provided with a fixing plate integrally formed with the mounting joint 6 on three sides, and the fixing plate is provided with a bearing hole at one end facing the center of the grinding frame 1, and the spherical bearing 24 to be ground is assembled in the bearing hole and waits for grinding. The clamping part includes a fixed clamping plate and a movable clamping plate 4. The fixed clamping plate is integrally formed on one side end surface of the grinding frame 1, and the movable clamping plate 4 is arranged opposite to the fixed clamping plate. A clamping interval is formed between the movable clamping plate 4 and the fixed clamping plate. The mounting joint 6 is placed in the clamping interval. The movable clamping plate 4 is installed on the grinding frame 1 by means of a fixing bolt 3. A locking bolt is also provided on the movable clamping plate 4. The locking bolt is perpendicular to the mounting joint 6. The mounting joint 6 is fastened between the movable clamping plate 4 and the fixed clamping plate by means of the locking bolt.

[0049] When clamping the spherical bearing 24 to be ground, after assembling the spherical bearing 24 into the bearing hole, place the mounting joint 6 between the movable clamp plate 4 and the fixed clamp plate, and tighten the mounting joint 6 by adjusting the locking bolt to complete the clamping of the spherical bearing 24 on the grinding frame 1.

[0050] After the spherical bearing 24 is clamped on the grinding frame 1, in order to grind the spherical bearing 24, see Figures 1 to 16 As shown, a power input assembly is provided at one end of the grinding frame 1 relative to the processing position, and the power input assembly includes an input driving shaft 7, an input gear, and a source driving wheel 8. Among them, a through hole is provided on the grinding frame 1 for the input driving shaft 7 to extend from the outside to the inside of the grinding frame 1, and a first bushing 21 is installed in the through hole, and the input driving shaft 7 passes through the first bushing 21, and the two are connected by a bearing for rotation. The input gear is fixedly installed on the inner end of the input driving shaft 7 located on the grinding frame 1, and the input gear and the source driving wheel 8 are meshed with each other.

[0051] Furthermore, the power output assembly includes a driving wheel 2, an adjusting rod 15, a force measuring rod 11 and a rocker arm 12. The driving wheel 2 and the driving wheel 8 are fixedly assembled on the same rotating shaft 20 through a key 23. Driven by the driving wheel 8, the driving wheel 2 rotates synchronously. A second bushing 22 is assembled on the middle position of the rotating shaft 20 through a bearing. The second bushing 22 is fixedly installed on a support, and the support is fixed inside the grinding frame 1, thereby installing and positioning the driving wheel 2 and the driving wheel 8. At the same time, an adjusting hole 13 is eccentrically arranged on the radial end face of the driving wheel 2. The adjusting rod 15 is fixed in the adjusting hole 13 through a positioning bolt 14. One end of the force measuring rod 11 is hinged to the end of the adjusting rod 15 away from the adjusting hole 13, and at the same time, the other end of the force measuring rod 11 is hinged to the rocker arm 12. Of course, it is not difficult to understand that in order to be able to grind joint bearings 24 of different models and increase the practicability and versatility of the device, as Figure 14 shown, multiple groups of adjusting holes 13 can be arranged in an array along a certain radial straight line on the driving wheel 2. By fixing the adjusting rod 15 in the adjusting holes 13 at different positions, the grinding of joint bearings 24 of different models can be realized.

[0052] In the above, the tightening assembly includes a tensioning shaft 17 and tensioning claws 19. One end of the rocker arm 12 away from the force measuring rod 11 is integrally formed with a bushing. The rocker arm 12 is sleeved on the tensioning shaft 17 through its bushing end, and an adjusting bearing 18 is assembled between the bushing and the tensioning shaft 17, so that the rocker arm 12 and the tensioning shaft 17 are rotatably connected. One end of the tensioning shaft 17 away from the rocker arm 12 extends into the inner ring of the joint bearing 24, and at least three tensioning claws 19 are circumferentially arranged at the end of the tensioning shaft 17 extending into the joint bearing 24. At the same time, a tensioning claw adjusting screw for axially moving is arranged at the end of the tensioning shaft 17 where the tensioning claws 19 are located. Through the tensioning claw adjusting screw 25, the length of all the tensioning claws 19 extending outwards can be adjusted to be able to tighten the inner ring of different joint bearings 24. Of course, conventionally, the adjustment of the telescopic adjustment of the tensioning claw adjusting screw for the tensioning claws 19 is the same as the adjustment principle of the traditional three-jaw chuck, and will not be elaborated here.

[0053] As can be seen from the above, after the assembly of the joint bearing is completed, through external power, which can be a motor or a pneumatic tool, it is connected to the input driving shaft 7, and then through the input driving shaft 7 and the gear meshing method, the driving wheel 8 is driven to rotate. The driving wheel 8 drives the driving wheel 2 to make a rotational motion through the rotating shaft 20 and the key 23. The driving wheel 2 drives the force measuring rod 11, the rocker arm 12 and the adjusting rod 15 through the adjusting hole 13 and the positioning bolt 14, so that the rocker arm 12 makes an elliptical motion in space, and the tensioning shaft 17 makes an elliptical motion in space through the adjusting bearing 18. Finally, the joint bearing 24 makes an elliptical motion in space, and then the inner and outer rings of the joint bearing are ground.

[0054] As one of the inventive points of the present application, to illustrate that the movement of the spherical plain bearing is an elliptical movement, the following detailed analysis is made:

[0055] Let the angular velocity of the input driving shaft 7 be ω0, and the tooth number ratio of the input driving shaft 7 to the driving wheel 8 be i 78 , and the distances AC between the hole axes of the respective adjustment holes 13 on the driving wheel 2 and the axis of the driving wheel 2 are each r 1 、r 2 、r 3 ......r i (i = 1, 2,..., N). The distance CB between the axis of the positioning bolt 14 and the axis of the tensioning shaft 7 is l, and the distance AB between the axis of the driving wheel 2 and the axis of the tensioning shaft 17 is k; the outer diameter EB of the adjusting bearing 18 is y1, and with the center point A of the axis of the driving wheel 2 as the origin, a plane coordinate system is established, the positive direction of the X-axis is the direction indicated by AB, and the positive direction of the Y-axis is the direction perpendicular to the X-axis, as Figure 17 shown, it can be known that:

[0056] Since the angular velocity of the driving shaft 7 is ω0, according to the tooth number ratio of the input driving shaft 7 to the driving wheel 8 being i 78 , the angular velocity of the driving wheel 2 is ω = ω0 × i 78 ; the included angle Φ between the straight lines CA and BA is Φ = ω0 × i 78 × t (t is the time).

[0057] Then the line segment AF = r i × cos(ω0 × i 78 × t), the line segment CF = r i × sin(ω0 × i 78 × t), and the line segment FB = AB- AF = K - r i × cos(ω0 × i 78 × t); because it can be obtained that

[0058]

[0059] it can be obtained that AG = AB-GB = K - {[K - r i × cos(ω0 × i 78 × t)] × y1} / L, that is, the abscissa of point E is XE = K - {[K - r i × cos(ω0 × i 78 × t)] × y1} / L.

[0060] Similarly, that is, the ordinate of point E is YE = r i × sin(ω0 × i 78×t)×y1 / L。

[0061] That is, the motion parametric equation of point E is:

[0062]

[0063] where ω0, K, L, i 78 , y1, r i are physical characteristic parameters, and the general equation is:

[0064]

[0065] It can be clearly seen from Equation (2) that point E has an elliptical motion trajectory, and point E is the motion trajectory of the rocker arm 12. Since the tensioning shaft 17 moves synchronously with the rocker arm, the tensioning shaft 17 performs an elliptical motion in space, and further causes the spherical plain bearing 24 to perform an elliptical trajectory motion in space.

[0066] Meanwhile, during the grinding process of the spherical plain bearing 24, the force measuring rod 11 will be periodically subjected to tension and pressure according to the friction force between the inner and outer rings of the spherical plain bearing 24. According to Hooke's law F = k×Δx, when the friction force between the inner and outer rings of the spherical plain bearing 24 is large, the value of the tension or pressure received by the force measuring rod 11 is large; when the friction force between the inner and outer rings of the spherical plain bearing 24 is small, the value of the tension or pressure received by the force measuring rod 11 is small.

[0067] During the grinding process of the spherical plain bearing 24, since the spherical plain bearing 24 performs an elliptical motion, the friction force between its inner and outer rings shows a periodic change, and the value of the tension or pressure received by the corresponding force measuring rod 11 also shows a periodic change. As Figure 18 shown is the force change measured by the force measuring rod during the grinding process. Therefore, from Figure 18 it can be seen that only by measuring the required acting force during the grinding process through the force measuring rod 11 and observing the measured force value data, when the tension or pressure received by the force measuring rod 11 tends to be stable, the grinding process of the spherical plain bearing has met the requirements. Thus, it can be determined whether the spherical plain bearing is ground to meet the requirements by whether the force measured by the force measuring rod tends to be stable, and whether the grinding of the inner and outer rings of the spherical plain bearing is in place can be accurately judged.

[0068] It can be understood that a tension sensor is provided at one end of the force measuring rod 11 connected to the rocker arm 12. The tension sensor is connected to the rocker arm 12 and can measure the acting force received.

[0069] In a preferred embodiment, as Figures 1 to 9As shown in the figure, a grinding paste storage tank 9 is further provided on the top side of the grinding rack 1 near the processing station. The top of the grinding paste storage tank 9 is provided with a filling port, and a sealing cover 10 is arranged at the filling port. By opening the sealing cover 10, the grinding paste can be filled into the grinding paste storage tank 9. The bottom of the grinding paste storage tank 9 is provided with a grinding paste diversion pipe 16 facing the spherical plain bearing 24. During the grinding process, the grinding paste is sprayed between the inner ring and the outer ring of the spherical plain bearing 24.

[0070] As can be seen from the above, for the spherical plain bearing 24 grinding device provided by the embodiment of the present application, its grinding and detection method is as follows:

[0071] First, the spherical plain bearing 24 to be ground is assembled to the mounting joint 6, and then the mounting joint 6 is placed between the fixed clamping plate and the movable clamping plate 4, and the mounting joint 6 is fastened to the grinding rack 1 by using the fastening bolt 5.

[0072] Next, the tensioning shaft 17 is inserted into the inner ring of the spherical plain bearing 24, and the tensioning claw 19 is adjusted and fixed to the inner ring of the spherical plain bearing 24 by adjusting the tensioning claw screw 25.

[0073] Then, the operator drives the input drive shaft 7 to rotate by docking a pneumatic tool (or it can also be a motor) with the input drive shaft 7. Through the input drive shaft 7 and the gear meshing method, the driving wheel 8 is driven to rotate. The driving wheel 8 drives the driving pulley 2 to make a rotational motion through the rotating shaft 20 and the key 23. The driving pulley 2 drives the force measuring rod 11, the swing arm 12 and the adjusting rod 15 to move through the adjusting hole 13 and the positioning bolt 14, so that the swing arm 12 makes an elliptical motion in space, and the tensioning shaft 17 makes an elliptical motion in space through the adjusting bearing 18. Finally, the spherical plain bearing 24 makes an elliptical motion in space, so as to grind the inner and outer rings of the spherical plain bearing 24.

[0074] During the grinding process, by observing the change of the force value measured by the force measuring rod 11, when the measured force value gradually tends to be stable and there is no obvious change, it indicates that the grinding of the inner and outer rings of the spherical plain bearing 24 is in place. At this time, the spherical plain bearing 24 can be disassembled for the next round of grinding.

[0075] In summary, the joint bearing grinding device provided by the embodiments of the present application fixes the joint bearing to be ground on the grinding frame by setting a fixing component, a power input component, a power output component, and a tightening component on the grinding frame. The tightening component is respectively connected to the power output component and the joint bearing. The power input component drives the joint bearing to perform an elliptical motion through the power output component, so that the inner and outer rings of the joint bearing have relative motion to achieve mutual grinding. Based on the mutual friction between the inner and outer rings of the joint bearing during the grinding process, the measuring rod is periodically subjected to tensile and compressive forces during the grinding process. When the tensile or compressive force received by the measuring rod tends to be stable, the grinding process of the joint bearing has met the requirements. Therefore, the joint bearing grinding device proposed based on the present application can realize automatic grinding of the joint bearing and can accurately and autonomously judge whether the grinding meets the requirements.

[0076] The foregoing is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
