[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] Please see Figures 1-8 The figure shows a comprehensive testing fixture for a gear selector shaft and shifter assembly, including a testing bench 2 for testing the gear selector shaft and shifter assembly. The gear selector shaft and shifter assembly includes a shaft body 101, on which multiple shifter bodies 102 are mounted. The shifter bodies 102 are rotatably connected to the shaft body 101. The shaft body 101 has a positioning groove 103 for assisting in gear selection and positioning. The fixture also includes:

[0032] A support assembly is provided on the inspection table 2 to assist in the support and placement of the shaft 101;

[0033] A clamping assembly is provided on the inspection table 2 to clamp and fix the shaft 101 after it has been supported and placed.

[0034] In addition, a first verification component for verifying the outer dimensions of the shaft 101 is provided on the inspection table 2, a second verification component for verifying the position of the push block body 102 is provided on the inspection table 2, and a detection component for detecting the position of the positioning groove 103 is provided on the inspection table 2.

[0035] It should be noted that during the verification process of the shift shaft and shift block assembly using the verification tool, the positional dimensions of each shift block body 102, the outer diameter of the shaft body 101, and the positional dimensions of the positioning groove 103 on the shift shaft and shift block assembly are verified through the cooperation of components such as the support component, clamping component, first verification component, second verification component, and detection component. The operation is simple and highly accurate, making it convenient for verification.

[0036] Preferably, multiple sets of support components are provided above the inspection table 2;

[0037] It should be noted here that the support effect is ensured by using multiple sets of support components.

[0038] Preferably, the support assembly includes a support frame 301 fixed to the upper end of the inspection table 2. The support frame 301 has an arc-shaped groove 302. The interior of the arc-shaped groove 302 is fixed with multiple sets of support pads 303 for supporting the outer side of the shaft 101 in a ring array.

[0039] It should be noted here that: during the verification of the shift shaft and shift block assembly using the testing tool, the shift shaft and shift block assembly are placed on the testing table 2. During the placement process, the shaft body 101 of the shift shaft and shift block assembly is respectively locked inside the arc-shaped groove 302 of the support frame 301. During the locking process, multiple sets of support pads 303 inside the arc-shaped groove 302 abut against different positions on the outside of the shaft body 101 to support the shaft body 101 after placement.

[0040] Preferably, the clamping assembly and the support assembly are symmetrically arranged on both sides of the shaft 101. The clamping assembly includes a pressure head 401 disposed above the inspection table 2. A first push clamp 402 for squeezing and pushing the pressure head 401 is installed on the inspection table 2.

[0041] It should be noted here that after the shaft 101 is supported and positioned, the pressure head 401 is pushed by the first push clamp 402, so that the pressure head 401 abuts and presses against the other side of the shaft 101. Through the auxiliary support and abutment of the shaft 101, the effect of limiting the installation of the shaft 101 on the selector shift shaft and shift block assembly is achieved.

[0042] In addition, it should be further explained that the first push-type clamp 402 is a conventional telescopic push component, which is considered prior art in this application. Its working principle and operation method will not be described in detail here.

[0043] Preferably, the first verification component includes a first mounting bracket 601 fixed on the inspection table 2, and a valid verification plate 602 is connected to the first mounting bracket 601 via a first adjustment component. The verification plate 602 is provided with a C-shaped verification groove 603 for the shaft 101 to be clamped and verified.

[0044] It should be noted here that after positioning, supporting and limiting the shaft 101, the corresponding dimensions of the shaft 101 are verified. During the verification process, when the outer diameter of the shaft 101 meets the requirements, the shaft 101 will be inserted into and fit into the C-shaped verification groove 603 of the verification plate 602 during the actual placement and limiting process. However, when the outer diameter of the shaft 101 is abnormal, the shaft 101 will not be able to be inserted into and fit into the C-shaped verification groove 603 of the verification plate 602 during the actual placement and limiting process, or there will be a large gap between the shaft 101 and the C-shaped verification groove 603 after the shaft 101 cannot be inserted into the C-shaped verification groove 603. This allows for a rapid determination of the outer diameter of the shaft 101.

[0045] Preferably, the first adjustment component includes a first slide groove 701 formed on the first mounting bracket 601, a first slide plate 702 slidably connected inside the first slide groove 701, a verification plate 602 fixed to the front end of the first slide plate 702, a first drive handle 703 for assisting in driving the first slide plate 702 fixed to the other end of the first slide plate 702, and a first pressure plate 704 for pressing and fixing the adjusted first slide plate 702 is detachably installed on the first mounting bracket 601 by bolts.

[0046] It should be noted that: by sliding the first slide plate 702 on the first slide groove 701, the position of the test plate 602 can be adjusted. The first drive handle 703 facilitates the driving of the first slide plate 702. After the first slide plate 702 is slidably adjusted, the first pressure plate 704 is installed and connected to the first mounting bracket 601. During the installation process, the first pressure plate 704 abuts against the first slide plate 702, and the abutting action limits the adjusted first slide plate 702.

[0047] Preferably, multiple sets of second verification components are provided, and each set of second verification components corresponds to a different set of toggle block bodies 102.

[0048] It should be noted here that: by using multiple sets of second verification components, it is convenient to verify the positions of multiple sets of toggle block bodies 102 in sequence.

[0049] Preferably, the second verification component includes a verification frame 801 for verifying the locking of the block body 102. The upper end of the verification frame 801 is detachably installed with a limiting plate 802 for fixing the block body 102 after locking by bolts. The inspection table 2 is provided with a second adjustment component for adjusting the position of the verification frame 801.

[0050] It should be noted here that after supporting and placing the shaft 101 of the shift shaft and shift block assembly, the position of each set of shift block bodies 102 is verified. During the verification process, each set of shift block bodies 102 is sequentially inserted into the verification frame 801. During the verification process, according to the initial position of the shift block bodies 102 to be inserted, the shaft 101 is axially moved so that the first set of shift block bodies 102 can be properly inserted into the corresponding verification frame 801. After the first set of shift block bodies 102 is engaged, the limiting plate is... 802 is threadedly connected to the verification frame 801. During the connection process, the limiting plate 802 abuts against the inserted lever body 102 to limit and fix the first set of verified lever bodies 102. This process is repeated for other sets of lever bodies 102. During the verification process of other sets, if at least one set of lever bodies 102 cannot be properly inserted into the verification frame 801 at the corresponding position, it is determined that the position of each set of lever bodies 102 on the shift shaft and lever assembly is abnormal.

[0051] Preferably, the second adjustment component includes a second mounting bracket 901 fixed to the upper end of the inspection table 2, a second sliding groove 902 provided on the second mounting bracket 901, a second sliding plate 903 slidably connected inside the second sliding groove 902, an inspection frame 801 fixed to the front end of the second sliding plate 903, a second drive handle 905 fixed to the other end of the second sliding plate 903 for assisting in driving the second sliding plate 903, and a second pressure plate 904 for pressing and fixing the adjusted second sliding plate 903 is detachably installed on the second mounting bracket 901 by bolts;

[0052] It should be noted that: the sliding of the second slide plate 903 on the second slide groove 902 facilitates the adjustment of the position of the verification frame 801. The second drive handle 905 facilitates the driving of the second slide plate 903. After the second slide plate 903 has moved, the second pressure plate 904 is threadedly connected to the second mounting bracket 901. During the connection process, the second pressure plate 904 abuts against the second slide plate 903. Through the abutting and squeezing action, the adjusted second slide plate 903 is limited and fixed.

[0053] Preferably, the detection assembly includes an inspection pin 502 disposed above the inspection table 2 for detecting against the positioning groove 103, a fixing frame 501 is mounted on the inspection table 2, and a second push-type clamp 503 for telescopically driving the inspection pin 502 is mounted on the fixing frame 501.

[0054] It should be noted here that: the second push clamp 503 pushes the inspection pin 502, causing the inspection pin 502 to move toward the positioning groove 103 of the shaft 101. During the movement, when the inspection pin 502 abuts against the positioning groove 103, it is determined that the position of the positioning groove 103 is normal. Otherwise, it is determined to be abnormal, thereby completing the rapid verification operation of the shift shaft and shift block assembly.

[0055] In addition, it should be further explained here that the second push-type clamp 503 is a conventional telescopic push component, which is considered prior art in this application. Its working principle and operation method will not be described in detail here.

[0056] In this solution, a comprehensive testing fixture for a selector shift shaft and shift block assembly includes the following steps:

[0057] During the verification process of the shift shaft and shift block assembly using the testing tool, the shift shaft and shift block assembly are placed on the testing table 2. During the placement process, the shaft body 101 of the shift shaft and shift block assembly is respectively locked into the arc groove 302 of the support frame 301. During the locking process, multiple sets of support pads 303 inside the arc groove 302 abut against different positions on the outside of the shaft body 101 to support the shaft body 101 after placement.

[0058] After supporting and placing the shaft 101 of the shift shaft and shift block assembly, the position of each set of shift block bodies 102 is verified. During the verification process, each set of shift block bodies 102 is sequentially inserted into the verification frame 801. During the verification process, according to the initial position of the shift block bodies 102 to be inserted, the shaft 101 is axially moved so that the first set of shift block bodies 102 can be properly inserted into the corresponding verification frame 801. After the first set of shift block bodies 102 is engaged, the limiting plate 802 and the verification frame are then engaged. The test frame 801 is threaded together. During the connection process, the limiting plate 802 abuts against the inserted lever body 102 to limit and fix the first set of tested lever bodies 102. This process is repeated for other sets of lever bodies 102. During the testing of other sets of lever bodies 102, if at least one set of lever bodies 102 cannot be properly inserted into the test frame 801 at the corresponding position, it is determined that the position of each set of lever bodies 102 on the shift shaft and lever assembly is abnormal.

[0059] Once each set of lever bodies 102 can be properly locked inside the verification frame 801, the interaction between each set of verification frames 801 and lever bodies 102 limits the position of the selected shift shaft and lever assembly shaft 101 after support and placement. After the shaft 101 is supported and positioned, the first push clamp 402 pushes the pressure head 401, causing the pressure head 401 to press against the other side of the shaft 101. Through the auxiliary support and pressing against the shaft 101, the effect of limiting the installation of the shaft 101 on the selected shift shaft and lever assembly is achieved.

[0060] After positioning, supporting, and limiting the shaft 101, the corresponding dimensions of the shaft 101 are verified. During the verification process, when the outer diameter of the shaft 101 meets the requirements, the shaft 101 will fit into and conform to the C-shaped verification groove 603 of the verification plate 602 during placement and limiting. However, when the outer diameter of the shaft 101 is abnormal, the shaft 101 will not fit into and conform to the C-shaped verification groove 603 of the verification plate 602 during placement and limiting, or the shaft 101 will not fit into the C-shaped verification groove 603. There is a large gap between the type 603 and the type C-type inspection groove 603, which enables rapid judgment of the outer diameter of the shaft 101. After the outer diameter of the shaft 101 is judged, the inspection pin 502 is pushed by the second push clamp 503, so that the inspection pin 502 moves toward the positioning groove 103 of the shaft 101. During the movement, when the inspection pin 502 abuts against the positioning groove 103, it is determined that the position of the positioning groove 103 is normal. Otherwise, it is determined to be abnormal, thus completing the rapid inspection operation of the shift shaft and shift block assembly.
