Therefore, its processing accuracy requirements are also high.

[0003] The gear hub usually has a three-groove structure, that is, the outer ring is the tooth body and three evenly distributed slider grooves, and there is a symmetry requirement relative to the external spline teeth on both sides of the slider groove to prevent the slider groove and the groove body of the external spline tooth from being too small and causing assembly failure. At present, the symmetry detection of the slider groove and the external spline tooth is mostly carried out sequentially and independently, that is, the detection device needs to complete the detection of the three slider grooves in turn, and then detect each external spline tooth in turn. The whole detection process is inefficient and time-consuming, which is not conducive to the rapid detection of the synchronizer gear hub. Utility Model Content

[0027] Among them, three first mounting rods 4 and multiple second mounting rods 5 are penetrated and slidably connected to the side wall of the mounting seat 3, the bottom of the first mounting rod 4 is fixedly connected to a detection slider 1 6, the bottom of the second mounting rod 5 is fixedly connected to a detection slider 2 7, and the outer surfaces of the first mounting rod 4 and the second mounting rod 5 are respectively sleeved with a detection spring 1 8 and a detection spring 2 9; the bottom of the detection spring 1 8 is fixedly connected to the upper surface of the detection slider 1 6, the bottom of the detection spring 2 9 is fixedly connected to the upper surface of the detection slider 2 7, and the tops of the detection spring 1 8 and the detection spring 2 9 are both fixedly connected to the lower surface of the mounting seat 3.

[0028] Reference Figure 1 and Figure 3 As shown, in order to achieve the purpose of adjusting the position of the movable mounting block 12, the upper surface of the mounting seat 3 is connected to the mounting plate 11 through the connecting rod 10, and the mounting plate 11 is connected to the movable mounting block 12 through a driving mechanism. The driving mechanism includes a servo motor 18 fixedly mounted on the upper surface of the mounting plate 11, and the driving shaft of the servo motor 18 penetrates downward through the mounting plate 11 and is fixedly connected to a driving gear 19. The lower surface of the mounting plate 11 is rotatably connected to an internal gear ring 20 meshing with the driving gear 19, and the movable mounting block 12 is fixedly connected to the internal gear ring 20.

[0029] Among them, a pressing mechanism for pressing the first mounting rod 4 or the second mounting rod 5 is installed on the side wall of the movable mounting block 12, and the pressing mechanism includes a driving cylinder 13 that passes through the movable mounting block 12 and is fixedly connected to the movable mounting block 12, and a detection pressure plate 14 is fixedly connected to the bottom piston end of the driving cylinder 13.

[0030] The functional principle of the utility model can be explained through the following operation modes:

[0031] The synchronizer gear hub to be tested is sleeved on the positioning column 2, and the servo motor 15 is started. The servo motor 15 drives the adjusting screw 16 to rotate. At this time, the mounting seat 3 as a whole starts to move downward along the limit rod 17, that is, the detection slider 1 6 and the detection slider 2 7 move downward synchronously.

[0032] The downward-moving detection slider 1 6 is gradually inserted into the slider groove, and the detection slider 2 7 is gradually inserted between adjacent external spline teeth. In this way, when the groove diameter of the slider groove to be tested is too small, the detection slider 1 6 cannot enter the corresponding slider groove. At this time, the detection spring 1 8 begins to be squeezed by the force, and the first mounting rod 4 moves upward, that is, the top of the first mounting rod 4 begins to protrude from the mounting plate 11. In this way, the inspection personnel can quickly determine the slider groove where the inspection problem occurs. Similarly, when the groove diameter between two adjacent external spline teeth is too small, the corresponding detection slider 2 7 cannot be inserted, and the top of the second mounting rod 5 connected to the detection slider 2 7 protrudes from the mounting plate 11.

[0033] When the top of the first mounting rod 4 protrudes from the mounting plate 11, in order to prevent the detection error caused by excessive friction between the detection slider 16 and the corresponding slider groove wall, the servo motor 2 18 can also be started. The servo motor 2 18 drives the inner gear ring 20 to rotate through the driving gear 19. At this time, the mobile mounting block 12 moves as a whole until the detection pressure plate 14 moves to the top of the corresponding first mounting rod 4, and the driving cylinder 13 is started. The piston end of the driving cylinder 13 pushes the detection pressure plate 14 to move downward and pushes the corresponding first mounting rod 4 to move downward. If the first mounting rod 4 makes the detection slider 1 6 can be inserted into the slider groove, which means that the slider groove meets the requirements. If the detection slider 1 6 still cannot be inserted into the slider groove, it means that the slider groove diameter is too small and does not meet the production requirements. Similarly, the detection pressure plate 14 can be used to further confirm the detection result of the detection slider 2 7 to ensure the accuracy of the detection result of the detection device. After the detection is completed, the servo motor 15 is started in the reverse direction to make the mounting seat 3 move up, the detection slider 1 6 and the detection slider 2 7 move up and align with the synchronizer gear hub, and then the synchronizer gear hub is removed from the positioning column 2.
