[0029] The following is in conjunction with the appendix Figure 1-14 The embodiments of the present invention will be described in detail.

[0030] A bearing ring positioning device includes a horizontal moving mechanism 1 and a vertical moving mechanism 2. The vertical moving mechanism 2 is mounted on the horizontal moving mechanism 1. A moving platform 3 is mounted on the vertical moving mechanism 2. A positioning block 4 and two fixing members 5 are mounted on the moving platform 3. A detection mechanism 6 and a drilling mechanism 7 are respectively mounted on the left and right sides of the moving platform 3. The fixing member 5 includes a fixing block 20 and a movable block 38 movably mounted inside the fixing block 20. Several limiting balls 45 are rotatably mounted inside the movable block 38. A cylinder 21 and a cylinder 22 are mounted on the moving platform 3. The piston rods of the cylinder 21 and the cylinder 22 are respectively connected to the outer surfaces of the movable block 38 and the fixing block 20. An air pump 39 and two control valves are mounted at the bottom of the moving platform 3. The control valves cooperate with the two fixing members 5 respectively. The control valves are used to control the movement of the piston rods in the cylinder 21 and the cylinder 22, thereby controlling the movement of the movable block 38 and the fixing block 20 respectively.

[0031] The control valve includes a valve body 46, inside which is a valve cavity 48. A valve body 49 is housed within the valve cavity 48. An air supply pipe 40 and an exhaust pipe 47 are located on one side of the valve body 46, and connecting pipes 1, 2, 3, 46, and 57 are located on the other side of the valve body 46. The inner ends of the air supply pipe 40, exhaust pipe 47, connecting pipes 1, 2, 3, 4, and 57 are connected to the valve cavity 48. An inlet connecting pipe 50 and an outlet connecting pipe 57 are located on the valve body 49. The valve body 49 has three connecting pipes: inlet pipe 51, outlet pipe 54, and outlet pipe 55. Connecting posts 59 are attached to both ends of the valve body 49. The left end of the left connecting post 59 protrudes from the valve body 46 and is connected to a stop block 60. The right end of the right connecting post 59 protrudes from the valve body 46 and is connected to a stop block 62. Springs 61 are fitted onto the portions of the connecting posts 59 that protrude from the valve body 46. When the valve body 49 moves to the right side of the valve chamber 48, the inlet pipe 50 connects to the supply pipe 40 and the connecting pipe 52. 51 connects to exhaust pipe 47 and connecting pipe 2 53; when valve body 49 moves to the left side of valve chamber 48, intake connecting pipe 2 54 connects to air supply pipe 40 and connecting pipe 3 56, and exhaust connecting pipe 2 55 connects to exhaust pipe 47 and connecting pipe 4 57. Cylinder 1 21 is equipped with cylinder 1 intake pipe 42 and cylinder 1 exhaust pipe 41. Connecting pipe 1 52 and connecting pipe 2 53 are respectively connected to cylinder 1 intake pipe 42 and cylinder 1 exhaust pipe 41. Cylinder 2 22 is equipped with cylinder 2 intake pipe 44 and cylinder 2 exhaust pipe 45. Air pipe 43, connecting pipe three 56 and connecting pipe four 57 are respectively connected to the air inlet pipe 44 and the air outlet pipe 43 of cylinder two. Air pump 39 is connected to air supply pipe 40. Detection mechanism 6 includes abutment post one 75, which cooperates with abutment block one 60. Drilling mechanism 7 includes abutment post two 83, which cooperates with abutment block two 62. When the moving stage 3 moves to the detection mechanism 6, abutment post one 75 abuts against abutment block one 60, causing valve body 49 to move to the right side position inside valve chamber 48. At this time, the intake connecting pipe 50 connects to the air supply pipe 40 and the connecting pipe 52, and the exhaust connecting pipe 51 connects to the exhaust pipe 47 and the connecting pipe 53. The gas in the air pump enters the cylinder 21 through the air supply pipe 40, the intake connecting pipe 50, the connecting pipe 52, and the cylinder intake pipe 42, causing the piston rod of the cylinder 21 to move inward, thereby pushing the movable block 38 inward, so that the limiting ball 45 abuts against the groove of the bearing ring. At this time, the bearing ring can still rotate even when it is abutted. During the rotation of the bearing ring, the outer diameter is detected by the detection mechanism 6.

[0032] When the moving stage 3 moves to the drilling mechanism 7, the second abutment post 83 abuts against the second abutment block 62, causing the valve body 49 to move to the left side position within the valve chamber 48. At this time, the second air inlet connecting pipe 54 connects to the air supply pipe 40 and the third connecting pipe 56, and the second air outlet connecting pipe 55 connects to the exhaust pipe 47 and the fourth connecting pipe 57. The gas in the air pump enters the second cylinder 22 through the air supply pipe 40, the second air inlet connecting pipe 54, the third connecting pipe 56, and the second cylinder inlet pipe 44, causing the piston rod of the second cylinder 22 to move inward, thereby pushing the fixed block 20 inward. The inner side of the fixed block 20 abuts against the outer wall of the bearing ring, completing the fixation of the bearing ring. At this time, the drilling mechanism 7 performs drilling on the bearing ring.

[0033] In the two control valves, the abutment block 2 62 of the left control valve and the abutment block 1 60 of the right control valve are connected by a connecting rod, so that the two control valves operate synchronously.

[0034] Preferably, the vertical moving mechanism 2 includes a vertical base 12, on which a vertical lead screw 13 is rotatably mounted. A vertical lead screw motor 14 is housed inside the vertical base 12, driving the vertical lead screw 13 to rotate. The vertical lead screw motor 14 and the vertical lead screw 13 are connected by a gear mechanism. A vertical lead screw slider 17 is mounted on the vertical lead screw 13, with its upper end connected to the lower end of the moving platform 3. The horizontal moving mechanism 1 includes a horizontal base 8. A transverse lead screw 9 is rotatably mounted on the base 8. A transverse lead screw motor 10 is installed inside the transverse base 8. The transverse lead screw motor 10 drives the transverse lead screw 9 to rotate. The transverse lead screw 9 and the transverse lead screw motor 10 are connected by a pulley and a transmission belt. A transverse lead screw slider 15 is mounted on the transverse lead screw 9. The upper end of the transverse lead screw slider 15 is connected to the bottom of the vertical base 12. A guide rail 11 is mounted on the upper part of the transverse base 8. A guide block 16 that cooperates with the guide rail 11 is mounted on the lower part of the vertical base 12.

[0035] Preferably, the valve body 49 has two connecting cavities 63, and the valve body 46 has a vent 65 corresponding to the position below the sealing block 58. Each connecting cavity 63 is provided with a sealing block 58, and the top of the sealing block 58 is connected to a connecting rope 64. The other end of the connecting rope 64 is connected to the top wall of the connecting cavity 63. The inner ends of connecting pipe 1 52 and connecting pipe 3 56 are connected to one of the connecting cavities 63, and the inner ends of connecting pipe 2 53 and connecting pipe 4 57 are connected to the other connecting cavity 63. A mounting bracket 66 is provided on the vertical base 12, and a hydraulic cylinder 1 67 is provided in the mounting bracket 66. The upper end of the piston rod of the hydraulic cylinder 1 67 is connected to a lifting rod 68, which can extend into the connecting cavity 63 and drive the sealing block 58 to rise.

[0036] When the bearing rings are being loaded and unloaded, the moving table 3 moves to a position above the mounting bracket 66. The hydraulic cylinder 67 controls the extension of its piston rod, causing the lifting rod 68 to pass through the vent 65 and extend into the connecting cavity 63, thereby driving the sealing block 58 to rise. This prevents the sealing block 58 from blocking the connecting pipes 52, 56, 53, and 57, allowing them to communicate with the outside. The pistons in cylinders 21 and 22 can move freely, meaning the fixing block 20 does not fix the bearing rings, thus facilitating the loading and unloading operation.

[0037] The positioning block 4 has an inner movable groove 69, inside which is a movable block 70. Inside the movable block 70 is a rotating groove 71, inside which is a support 72. A detection ball 18 is rotatably mounted in the support 72. A trigger 73 is mounted on the left side wall of the movable groove 69. A spring 74 is connected to the left side of the movable block 70. The left end of the spring 74 is connected to the left side wall of the movable groove 69. An alarm 19 is mounted on the upper part of the positioning block 4. The alarm 19 and the trigger 73 are electrically connected.

[0038] The outer wall of the bearing ring is placed against the inner wall of the positioning block 4. If the placement is correct, the bearing ring first presses against the detection ball 18, causing the moving block 70 to move inward, making the moving block 70 contact the trigger 73. After the bearing ring is placed on the moving table 3, the groove on the bearing ring is aligned with the position of the detection ball 18. The moving block 70 then moves outward under the action of the spring 74, making the detection ball 18 contact the groove of the bearing ring. At this time, the moving block 70 and the trigger 73 separate, generating a contact-and-separation signal within a certain period of time, indicating that the bearing ring is placed correctly and subsequent operations can proceed. If the placement is incorrect, the bearing ring continues to press against the detection ball 18, keeping the moving block 70 in contact with the trigger 73, generating a continuous contact signal within a certain period of time, indicating that the bearing ring is placed incorrectly and subsequent operations cannot proceed. A signal is also sent to the alarm 19, causing the alarm 19 to sound an alarm to alert the staff.

[0039] The testing mechanism 6 includes a positioning frame 79, a hydraulic cylinder 76 on the right side of the positioning frame 79, a drive motor 77 on the piston rod of the hydraulic cylinder 76, a drive wheel 78 connected to the drive motor 77, a test gauge 80 on the right side of the positioning frame 79, and an abutment post 75 on the right side of the positioning frame 79.

[0040] Preferably, a central column 23 is positioned at the center of the movable platform 3. A support cylinder 25 is positioned around the central column 23 within the movable platform 3. Several support balls 26 are positioned on the upper part of the support cylinder 25. A first support ring 24 is positioned between the central column 23 and the support cylinder 25. A second support ring 27 is positioned around the outer periphery of the support cylinder 25. A lifting groove 28 is formed on the support cylinder 25. A connecting frame 29 is positioned within the lifting groove 28. The two ends of the connecting frame 29 are respectively connected to the lower ends of the second support ring 27 and the first support ring 24. A mounting groove 30 is provided below the groove 28. A spring 31 is installed in the mounting groove 30. The lower end of the spring 31 is connected to the bottom of the mounting groove 30. The upper end of the mounting groove 30 is connected to the lower end of the connecting frame 29. A linkage rod 33 is connected to the lower part of the connecting frame 29. A guide slope 35 is provided on the left side of the linkage rod 33. A notch 32 is provided on the moving table 3 corresponding to the position of the linkage rod 33. A trigger rod 36 is connected to the right side of the positioning frame 79. The trigger rod 36 is positioned corresponding to the notch 32. An abutment slope 37 is provided at the lower part of the trigger rod 36.

[0041] Under normal conditions, the uppermost ends of the support balls 26, support ring 24, and support ball 26 are flush with the upper surface of the moving stage 3, supporting the bearing race through support ring 24, support ring 27, and support balls 26. When the moving stage 3 moves to the detection mechanism 6, the right end of the trigger rod 36 extends into the moving stage 3 through the notch 32. The abutting inclined surface 37 on the trigger rod 36 contacts the guide inclined surface 35 on the linkage rod 33. As the moving stage 3 moves to the left, the trigger rod 36 abuts against the linkage rod 33, causing the linkage rod 33 to move downward. The linkage rod 33, through the connecting frame 29, drives support ring 27 and support ring 24 to descend, preventing support ring 27 and support ring 24 from contacting the lower end face of the bearing race. Only the support balls 26 support the bearing race. When the bearing race rotates, the lower end will not contact support ring 27 and support ring 24, thereby reducing friction, ensuring smooth rotation, and enabling better detection of the outer diameter. The moving stage 3 moves to the right away from the detection mechanism 6. Under the action of spring 31, the connecting frame 29 rises again, and the support ring 27 and support ring 24 support the bearing ring again.

[0042] The bottom of the mobile platform 3 is connected to several positioning rods 34. The positioning rods 34 pass through the linkage rod 33 and guide the linkage rod 33 to keep the linkage rod 33 vertically rising and falling.

[0043] Preferably, the drilling mechanism 7 includes a positioning frame 2 81, a mounting plate 82 is provided on the left side of the positioning frame 2 81, a hydraulic cylinder 3 85 is provided at the lower part of the mounting plate 82, a mounting seat 84 is connected to the lower part of the mounting plate 82, the hydraulic cylinder 3 85 is installed in the mounting seat 84, two guide bars 86 are connected to the lower part of the mounting plate 82, and a drive motor 2 87 is movably disposed between the two guide bars 86. The two guide bars 86 limit and guide the drive motor 2 87. The piston rod of the hydraulic cylinder 3 85 is connected to the drive motor 2 87, and the motor shaft of the drive motor 2 87 is connected to a drill bit 89 through a coupling 88. The drive motor 2 87 drives the drill bit 89 to rotate, and the drilling operation is performed on the bearing ring by the push of the hydraulic cylinder 3 85.
