[0030] Embodiment:

[0031] As Figures 1 to 7 shown, the present utility model provides a bearing bracket spatial position detection device, including an inspection table 1, on which a positioning seat 2 is fixedly installed. A positioning pin 3 and an inspection pin 6 for detecting the threaded mounting hole 5 on the bearing bracket 4 are arranged on the positioning seat 2. Above the positioning seat 2, a pressing mechanism 7 for pressing the bearing bracket 4 is symmetrically arranged. A plurality of inspection seats are arranged around the positioning seat 2. The inspection seats include a snap-tightening hole inspection seat 8, a bearing support hole inspection seat 9, and a snap-mounting hole inspection seat 10. The inspection pins 6 for detecting the corresponding hole positions on the bearing bracket 4 are respectively arranged on all the inspection seats.

[0032] An arc-shaped bearing support hole 18 is opened on the bearing bracket 4. Above the bearing support hole 18, a snap-tightening hole 19 is arranged. Below the bearing support hole 18, a snap-mounting hole 20 is arranged. Two threaded mounting holes 5 are arranged at the lower part of the bearing bracket 4. A positioning hole 21 is arranged on one side of each threaded mounting hole 5. The positioning hole 21 is adaptively inserted and positioned with the positioning pin 3. The inspection pin 6 on the positioning seat 2 is adapted to the threaded mounting hole 5. The inspection pin 6 on the snap-tightening hole inspection seat 8 is adapted to the snap-tightening hole 19. The inspection pin 6 on the bearing support hole inspection seat 9 is adapted to the bearing support hole 18. The inspection pin 6 on the snap-mounting hole inspection seat 10 is adapted to the snap-mounting hole 20.

[0033] Further, the pressing mechanism 7 includes a pressing bracket 71, a connecting groove plate 72, a pressing claw 73 and a lifting member 74. The pressing bracket 71 is fixedly installed on the inspection table 1. The connecting groove plate 72 is rotatably installed at the top of the pressing bracket 71. The pressing claw 73 is installed on the connecting groove plate 72. The pressing claw 73 presses against the periphery of the threaded mounting hole 5. The lifting member 74 is used to lift the pressing claw 73 to press downwards.

[0034] Specifically, a clamping plate 22 is provided on the connecting groove plate 72. The width of the clamping plate 22 is greater than the width of the groove on the connecting groove plate 72. A connecting rod 23 is installed on the clamping plate 22. The connecting rod 23 passes through the clamping plate 22 and the groove, and fixing nuts 24 are used to fix both ends of the connecting rod 23, thereby firmly fixing it on the connecting groove plate 72. The bottom of the connecting rod 23 is fixedly connected to the pressing claw 73. The pressing claw 73 extends forward to press against the threaded mounting hole 5. The position of the pressing claw 73 can be adjusted according to the actual height at the threaded mounting hole 5 of the bearing bracket 4 to ensure that when the pressing handle 743 is lowered, the pressing claw 73 can firmly press the bearing bracket 4.

[0035] Further, the lifting member 74 includes a connecting plate 741, a linkage plate 742 and a pressing handle 743.

[0036] Further, a protrusion 11 is provided on the front side of the linkage plate 742. The protrusion 11 abuts against the connecting groove plate 72.

[0037] When it is necessary to press the threaded mounting hole 5 on the bearing bracket 4, pull down the pressing handle 743. The movement of the pressing handle 743 drives the connecting plate 741 to rotate around the top of the pressing bracket 71, and then drives the rotation of the linkage plate 742. Since the lower end of the linkage plate 742 is rotatably connected to the connecting plate 741, the rotation of the linkage plate 742 drives the connecting plate 741 to rotate around the top of the pressing bracket 71, and then drives the connecting rod 23 and the pressing claw 73 to move upwards, so that the pressing claw 73 can be lifted, and the bearing bracket 4 can be placed in the corresponding position. Loosen the pressing handle 743 to press the bearing bracket 4.

[0038] Since a protrusion 11 is provided on the front side of the linkage plate 742, the protrusion 11 can exert a downward pressure on the pressing claw 73, achieving a good limiting and pressing effect.

[0039] Further, an adjusting mechanism 12 for adjusting the height of the detection pin 6 corresponding to the threaded mounting hole 5 is provided on the positioning seat 2.

[0040] Further, the adjusting mechanism 12 includes a lifting groove 121 and a sliding rod 122. The lifting groove 121 is opened on the side surface of the positioning seat 2. One end of the sliding rod 122 is fixedly connected to the detection handle on the detection pin 6, and the other end passes through the lifting groove 121 and is slidably connected thereto. The bottom of the detection handle is fixedly connected to the detection table 1 through a nut.

[0041] When it is necessary to adjust the height of the corresponding detection pin 6 according to the position of the threaded mounting hole 5 at the bottom of the bearing bracket 4, pull the sliding rod 122 to slide along the lifting groove 121. After adjusting to the appropriate position, use a nut to fix the position of the detection pin 6. The adjustment method is simple, meeting the needs of the spatial position detection of the bearing bracket, improving the detection accuracy, and having strong practicability.

[0042] Further, the buckle tightening hole detection seat 8 is arranged obliquely, so that the detection pin 6 on the buckle tightening hole detection seat 8 can be smoothly inserted into the buckle tightening hole 19 for detection. The detection pin 6 on the buckle tightening hole detection seat 8 is sleeved in the guide sleeve 13. The guide sleeve 13 is fixedly connected to the buckle tightening hole detection seat 8. The bottom of the detection pin 6 is fixedly connected to the through-stop slide bar 14. A sliding groove 15 is opened on the guide sleeve 13. The through-stop slide bar 14 passes through the sliding groove 15 and is slidably connected thereto. A locking groove 16 is arranged outside the sliding groove 15. The through-stop slide bar 14 slides into the locking groove 16 for fixation.

[0043] Further, the positioning pin 3 passes through the top of the positioning seat 2 and is slidably connected thereto. A spring 17 is fixedly installed at the bottom of the positioning pin 3. The bottom of the spring 17 is fixedly connected to the detection table 1. In this way, appropriate height adjustment can be made according to the position of the positioning hole 21 on the actual bearing bracket 4, so that the positioning pin 3 can be smoothly inserted into the positioning hole 21 for positioning operation, the positioning is more accurate, and the accuracy of the spatial position detection of the bearing bracket is increased.

[0044] The working principle of this embodiment is as follows:

[0045] First, according to the specific dimensions of the bearing bracket 4, use the adjusting mechanism 12 to adjust the position of the corresponding detection pin 6 and set it at the specified position.

[0046] During detection, place the bearing bracket 4 on the positioning seat 2 so that the positioning holes 21 on the bearing bracket 4 are adaptively inserted into the positioning pins 3 on the positioning seat 2. At the same time, insert the detection pin 6 on the positioning seat 2 into the threaded mounting hole 5 on the bearing bracket 4 for position detection. Then rotate the pressing handle 743 to press the clamping jaw 73 downward to press the bearing bracket 4. Then insert the corresponding detection pins 6 on all the detection seats into the corresponding holes on the bearing bracket 4 for position detection. If the bearing bracket 4 meets the corresponding dimensional standards, the detection pin 6 on the positioning seat 2 will be adapted to the threaded mounting hole 5, the detection pin 6 on the snap-tightening hole detection seat 8 will be adapted to the snap-tightening hole 19, the detection pin 6 on the bearing support hole detection seat 9 will be adapted to the bearing support hole 18, and the detection pin 6 on the snap-fitting hole detection seat 10 will be adapted to the snap-fitting hole 20.
