[0060] like Figure 3 and Figure 4 A locking handle assembly 1 is shown, which includes a spline shaft 11 and a locking plate 12. The spline shaft 11 is connected to one side of the locking plate 12, and the locking plate 12 is provided with a connecting hole; the spline shaft 11 is inserted into the connecting hole and welded to the locking plate 12; the locking plate 12 is provided with a first through hole 121, and the first through hole 121 is used to connect with the push rod of the driving device of the parking mechanism. The spline shaft 11 has a smooth portion 111 and a tooth portion 112, and the tooth portion 112 is located at one end of the smooth portion 111 away from the locking plate 12. The tooth portion 112 has a wide tooth 113, and the tooth width of the wide tooth 113 is greater than the tooth width of other teeth.

[0061] Figure 4 The line connecting the center of the middle spline shaft 11 and the center of the first through hole 121 is the first reference line; the line connecting the center of the spline shaft 11 and the center of the wide tooth 113 is the second reference line. The angle between the first reference line and the second reference line is designed according to a standard qualified angle according to actual conditions, and all angles within the angle error range are qualified.

[0062] The angle detected by the angle detection mechanism of the locking handle assembly provided in the present application is the angle between the first reference line and the second reference line.

[0063] Figures 1 to 10 An angle detection mechanism of a locking handle assembly provided in an embodiment of the present application includes a frame 2, a positioning device 3, a clamping device 4, and a detection device 5; the positioning device 3 is arranged on the frame 2, and the positioning device 3 includes a first positioning structure for positioning and assembling a spline shaft 11 and a second positioning structure for positioning and assembling a locking plate 12; the clamping device 4 is movably arranged on the frame 2, and the clamping device 4 is close to or away from the locking handle assembly 1 to clamp or loosen the locking handle assembly 1 and the positioning device 3; the detection device 5 is movably arranged on the frame 2, and the detection device 5 is provided with a spline gauge 531, and the spline gauge 531 is arranged corresponding to the spline shaft 11, wherein the detection device 5 drives the spline gauge 531 to move close to the spline shaft 11, and detects whether the installation angle of the spline shaft 11 on the locking plate 12 is qualified by whether the spline shaft 11 can be inserted into the spline gauge 531. In this way, qualified products and unqualified products can be screened out to provide qualified products and avoid the outflow of unqualified products.

[0064] In this way, the frame 2 provides an installation basis, and the positioning device 3 provides a positioning basis for the locking handle assembly 1. The spline shaft 11 of the locking handle assembly 1 is placed in the first positioning structure for positioning, and the locking plate 12 is placed in the second positioning structure for positioning, that is, the spline shaft 11 and the locking plate 12 can be fixed in position by the first positioning structure and the second positioning structure, and then the locking handle assembly 1 is clamped by the clamping device 4 to avoid position movement during subsequent inspections, and then the spline through gauge 531 of the inspection device 5 is checked to see whether it can be adapted to the spline shaft 11 to detect whether the installation angle of the spline shaft 11 on the locking plate 12 is qualified; when the deflection angle of the wide tooth 113 of the spline shaft 11 exceeds the error range, when the spline through gauge 531 moves to the vicinity of the spline shaft 11, the spline shaft 11 cannot be inserted into the spline shaft 11, indicating that the locking handle assembly 1 is unqualified. When the deflection angle of the wide teeth 113 of the spline shaft 11 is within the error range, and when the spline gauge 531 moves to the vicinity of the spline shaft 11, the tooth portion 112 of the spline shaft 11 can be smoothly inserted into the spline shaft 11, it indicates that the locking handle assembly 1 is qualified.

[0065] like Figures 1 to 6As shown, in the technical solution of this embodiment, the positioning device 3 includes a positioning seat 31 and a positioning pin 32. The positioning seat 31 is provided with a positioning groove 310. The positioning groove 310 extends along the axial direction of the spline shaft 11 to penetrate for positioning; the positioning groove 310 is a first positioning structure; the positioning pin 32 is arranged on the positioning seat 31 and corresponds to the first through hole 121; the positioning pin 32 is a second positioning structure.

[0066] It is understandable that setting the first positioning structure as the positioning groove 310 can facilitate the spline shaft 11 to be placed in the positioning groove 310 and to be taken out from the positioning groove 310. Inserting the positioning pin 32 into the first through hole 121 can simulate the matching state of the first through hole 121 and the push rod of the driving device when the first through hole 121 is installed. Figure 2 As shown, in one embodiment, the angle between the first reference line and the second reference line is designed to be 90°. After the spline shaft 11 and the locking plate 12 are positioned in the first positioning structure and the second positioning structure respectively, the first reference line is horizontal, and the detection device 5 is also arranged on the horizontal plane of the frame 2, which can improve the detection accuracy.

[0067] In one embodiment, a robot is further included, and the locking handle assembly 1 can be taken and placed by the robot to realize automatic operation and improve work efficiency. The robot can place qualified products at qualified stations and unqualified products at unqualified stations.

[0068] In one embodiment, a code reader is also included, which reads the code of the locking handle assembly 1, and after the inspection is completed, the inspection data of qualified and unqualified products are uploaded.

[0069] like Figure 5 and Figure 6 As shown, in the technical solution of this embodiment, the positioning pin 32 includes a positioning pin body 321 and an elastic member 322, the two ends of the elastic member 322 are respectively connected to the positioning seat 31 and the positioning pin body 321, and the positioning pin body 321 is adapted to the first through hole 121; wherein, when the clamping device 4 clamps the locking handle assembly 1 to the positioning device 3, the positioning pin body 321 is clamped to the first through hole 121, and the locking plate 12 squeezes the elastic member 322 through the positioning pin body 321. In this way, on the one hand, the hard collision between the positioning pin body 321 and the first through hole 121 can be reduced, and the locking handle assembly 1 can be protected. On the other hand, the locking plate 12 body is clamped between the clamping device 4 and the elastic member 322, which can improve the position stability of the locking plate 12.

[0070] In this embodiment, the frame 2 is provided with an assembly hole 323, the elastic member 322 is provided in the assembly hole 323, the positioning pin body 321 is movably inserted in the assembly hole 323, and partially extends out of the assembly hole 323. In this embodiment, the elastic member 322 is a spring.

[0071] like Figure 3 and Figure 4 As shown, in the technical solution of this embodiment, the hole wall of the first through hole 121 is provided with an error-proof groove 122; Figure 5 and Figure 6 As shown, the positioning device 3 further includes an anti-error block 33 , which is disposed on the positioning seat 31 and corresponds to the anti-error groove 122 .

[0072] It can be understood that the cooperation between the anti-misplacement block 33 and the misplacement groove can prevent the locking handle assembly 1 from being misplaced when placed on the positioning device 3. In this embodiment, there are two misplacement grooves, two misplacement blocks, and the two misplacement blocks are connected to a connecting ring at intervals. The connecting ring is sleeved outside the positioning pin body 321, and the connecting ring is connected to the frame 2.

[0073] like Figure 3 and Figure 4 As shown, in the technical solution of this embodiment, the locking plate 12 is further provided with a second through hole 123, and the second through hole 123 is spaced apart from the first through hole 121; Figure 5 and Figure 6 As shown, the positioning device 3 also includes an auxiliary support pin 34 disposed on the positioning seat 31, and the auxiliary support pin 34 is used to penetrate the second through hole 123. When the locking handle assembly 1 is placed on the positioning device 3, the auxiliary support pin 34 is inserted into the second through hole 123. When the locking handle assembly 1 is not positioned in place, the cooperation between the auxiliary support pin 34 and the second through hole 123 can prevent the locking handle assembly 1 from falling.

[0074] like Figure 1 As shown, in the technical solution of this embodiment, the clamping device 4 includes a first clamping assembly 41 and a second clamping assembly 42, which are movably arranged on the frame 2 and located above the positioning groove 310; movably arranged on the frame 2 and approaching or moving away from the positioning seat 31 along the axial direction of the positioning groove 310; wherein the second clamping assembly 42 and the detection device 5 are respectively located on both sides of the positioning seat 31. In this way, the first clamping assembly 41 can limit the spline shaft 11 in the vertical direction, the second clamping assembly 42 can limit the locking plate 12 in the horizontal direction, and the detection device 5 detects the angle of the spline shaft 11 on the side of the positioning seat 31 away from the second clamping assembly 42.

[0075] In this embodiment, the specific process of clamping the locking handle assembly 1 on the positioning device 3 is as follows: the locking handle assembly 1 is placed on the positioning device 3, wherein the spline shaft 11 is placed in the positioning groove 310, the positioning pin body 321 is inserted into the first through hole 121, and the auxiliary support pin 34 is inserted into the second through hole 123; then the first clamping component 41 moves to abut against the spline shaft 11, and then the locking plate 12 is pushed by the second clamping component 42, so that the locking plate 12 is clamped on the positioning seat 31.

[0077] In this embodiment, the first driving member 411 is a cylinder, which drives the first linking member 412 to move up and down, and then drives the roller 413 to move up and down to press or release the spline shaft 11. Figure 2 As shown, the roller 413 is pressed against the light portion 111 of the spline shaft 11. When the second clamping assembly 42 pushes the locking plate 12, the locking plate 12 drives the spline shaft 11 to move, and friction is generated between the roller 413 and the spline shaft 11. Since the roller 413 is rotatably connected to the end of the first linkage 412, rolling friction occurs between the roller 413 and the spline shaft 11, which can reduce friction and ensure that the spline shaft 11 can move smoothly.

[0080] In this embodiment, the second driving member 421 is a cylinder, which drives the second linking member 422 to move horizontally, and then drives the pushing member 423 to move horizontally to press or loosen the locking plate 12. Figure 2 As shown, the push member 423 is pressed against the side of the locking plate 12 away from the spline shaft 11 , and can push the locking handle assembly 1 to move until the locking plate 12 is clamped between the positioning seat 31 and the push member 423 .

In this way, the stability of the second clamping assembly 42 when pushing the locking plate 12 can be improved.

[0083] In this embodiment, there are two abutting pins 424 , and the two abutting pins 424 are symmetrically arranged.
