Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive transmission processing, specifically to a rapid testing device for transmission cam springs. Background Technology
[0002] The transmission cam spring is an important component in automotive transmissions, primarily used in synchronizers to help achieve smooth gear shifts. In the synchronizer, the transmission cam spring enhances the frictional torque generated by the synchronizer ring, making gear shifts more effortless and rapid. Through its supporting force, the transmission cam spring prevents the synchronizer ring from contacting the gears prematurely, avoiding shift shock and ensuring a smooth shifting process.
[0003] like Figure 1 The diagram shows the structure of a transmission cam spring. The transmission cam spring includes a main body, which comprises a fixed segment 11 and an elastic segment 12. The fixed segment has at least two mounting holes 15, and the free end of the elastic segment has a clearance groove 14, within which a roller 13 is connected. In the transmission, the fixed segment is fixedly connected via the two mounting holes, and the roller on the elastic segment provides the elastic force.
[0004] Due to their installation characteristics, the positional accuracy of the rollers in the transmission cam spring relative to the two base circle holes in the spring assembly is particularly important. Positional errors can affect component assembly, and even if the parts can be installed in the transmission, it can cause problems such as shifting jerks and difficulty in shifting. Therefore, it is necessary to inspect the relative positions of these features in the transmission cam spring to ensure its normal and reliable operation. Summary of the Invention
[0005] The technical problem to be solved by this utility model is to provide a rapid testing device for transmission cam springs, which has the advantages of simple structure, convenient operation and high testing efficiency.
[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a rapid testing device for transmission cam springs, comprising a base, a mounting module and a testing module, wherein the base is provided with an mounting station and a testing station; The installation module includes several positioning pins set at the installation station and a clamping component set on one side of the installation station; The detection module includes a detection pin, a horizontal detection component, and a vertical detection component. The detection pin is disposed at the detection station. The horizontal detection component includes a horizontally sliding slider, which is positioned opposite the installation station to the detection station. The side of the horizontal slider facing the detection station has a horizontal adaptation notch. The vertical detection component includes a vertically sliding slider, which is located above the detection station. The side of the vertical slider facing the detection station has a vertical adaptation notch.
[0007] During testing, the fixed segment of the transmission cam spring is placed in the installation position, with the mounting base hole on the fixed segment aligned with the locating pin. The fixed segment is then clamped by the clamping assembly, and the elastic segment of the transmission cam spring is tilted upwards. The system checks for interference between the clearance groove on the elastic segment and the detection pin. If interference exists, the clearance groove's position relative to the mounting base hole is deemed unacceptable. If there is no interference, the horizontal and vertical sliders are slid to check for alignment between the horizontal and vertical adaptation notches and the roller. If at least one of the horizontal and vertical adaptation notches is misaligned with the roller, the roller's position relative to the mounting base hole is deemed unacceptable.
[0008] The rapid testing device of this application can quickly test the positional accuracy of clearance grooves and rollers relative to mounting base holes. It has the advantages of simple structure, convenient operation and high testing efficiency, and is particularly suitable for large-volume rapid testing applications.

[0010] Preferably, the testing station is provided with a fixed mounting base, the fixed mounting base is provided with a slot, the testing pin is slidably connected to the slot, and a first spring is provided between the testing pin and the fixed mounting base.
[0011] The detection pin can be replaced for maintenance. Additionally, when the longitudinal slider slides downwards, the detection pin can slide down within a certain range to avoid obstruction, providing sufficient space for longitudinal detection.
[0012] Preferably, the lateral detection component further includes a lateral mounting base, wherein the lateral slider is horizontally disposed through the mounting base and is horizontally slidably connected to the mounting base.
[0013] Preferably, a second spring is provided between the transverse slider and the transverse mounting base. The second spring is used to drive the transverse slider to return to its original position, leaving space for the installation of the transmission cam spring and the movement of the longitudinal slider, thereby improving operational convenience.
[0014] Preferably, the longitudinal detection component further includes a longitudinal mounting base, which includes a column and a horizontal mounting arm. The horizontal mounting arm is connected to the base via the column and extends above the detection station. The longitudinal slider is longitudinally disposed through the horizontal mounting arm and is longitudinally slidably connected to the horizontal mounting arm.
[0015] Preferably, a third spring is provided between the longitudinal slider and the horizontal mounting arm. The third spring is used to drive the longitudinal slider to reset, leaving space for the installation of the transmission cam spring and the movement of the lateral slider, thereby improving operational convenience.
[0016] Preferably, the base has adjustable legs on its lower side; the base also has a handle. The rapid testing device can be transported as a whole, making it highly portable. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. Example
[0019] like Figures 2-4 As shown, a rapid testing device for transmission cam springs includes a base 2, a mounting module, and a testing module. The base 2 has a mounting station 32 and a testing station. In one specific embodiment, the base 2 has a support leg 22 on its lower side, and the length of the support leg 22 is adjustable. The base 2 has a handle 21. The rapid testing device can be transported as a whole, making it highly portable.
[0020] like Figures 2-4As shown, the installation module includes several positioning pins 33 disposed at the installation station 32, and a clamping assembly 31 disposed on one side of the installation station 32. Specifically, the clamping assembly 31 includes a clamping block 312 and a clamping drive component 311. The clamping block 312 is rotatably connected to the base 2, and the clamping drive component 311 is used to drive the clamping block 312 to rotate. The clamping drive component 311 includes a cylinder and a locking bolt. As a specific embodiment, the clamping drive component 311 includes a quick clamp. It should be noted that the quick clamp used in this embodiment is an existing type of clamp, so the specific structure of the quick clamp will not be described in detail.
[0021] like Figures 2-4 As shown, the detection module includes a detection pin 41, a transverse detection component, and a longitudinal detection component. The detection pin 41 is disposed at the detection station. Specifically, the detection station is provided with a fixed mounting base 4, which has a slot. The detection pin 41 is slidably connected to the slot, and a first spring 42 is provided between the detection pin 41 and the fixed mounting base 4. The detection pin 41 can be replaced and maintained. Simultaneously, when the longitudinal slider 53 slides downward, the detection pin 41 can slide down within a certain range to avoid obstruction, leaving sufficient space for longitudinal detection.
[0022] like Figures 2-4 As shown, the lateral detection component includes a horizontally sliding lateral slider 63, which is positioned opposite the installation station 32 to the detection station. The lateral slider 63 has a lateral adaptation notch 64 on the side facing the detection station. The longitudinal detection component includes a longitudinally sliding longitudinal slider 53, which is located above the detection station. The longitudinal slider 53 has a longitudinal adaptation notch 55 on the side facing the detection station.
[0023] Specifically, such as Figures 2-4 As shown, the transverse detection assembly further includes a transverse mounting base 61. The transverse slider 63 is horizontally disposed through the mounting base and is horizontally slidably connected to the mounting base. The end of the transverse slider 63 facing away from the detection station is the transverse operating end. The longitudinal detection assembly further includes a longitudinal mounting base. The longitudinal mounting base includes a column 51 and a horizontal mounting arm 52. The horizontal mounting arm 52 is connected to the base 2 through the column 51 and extends above the detection station. The longitudinal slider 53 is longitudinally disposed through the horizontal mounting arm 52 and is longitudinally slidably connected to the horizontal mounting arm 52. The end of the longitudinal slider 53 facing away from the detection station is the longitudinal operating end.
[0024] In one specific implementation, the horizontal slider 63 is driven by a cylinder, and the vertical slider 53 is driven by a cylinder.
[0025] As another specific implementation method, such as Figures 2-4 As shown, a second spring 62 is provided between the transverse slider 63 and the transverse mounting base 61, and a third spring 54 is provided between the longitudinal slider 53 and the horizontal mounting arm 52. Under normal conditions, the transverse slider 63 and the longitudinal slider 53 are both located away from the detection station. The second spring 62 drives the transverse slider 63 to reset, and the third spring 54 drives the longitudinal slider 53 to reset, providing space for the insertion of the transmission cam spring and also for sequential operation in both the transverse and longitudinal directions.
[0026] During testing, the fixed segment of the transmission cam spring 1 is placed in the mounting position 32, with the mounting base hole on the fixed segment aligned with the locating pin 33. The fixed segment is then pressed together by the clamping assembly 31, at which point the elastic segment of the transmission cam spring is tilted upwards. The system checks for interference between the clearance groove on the elastic segment and the detection pin 41. If interference exists, the position of the clearance groove relative to the mounting base hole is deemed unqualified. If there is no interference between the clearance groove on the elastic segment and the detection pin 41, the system slides the transverse slider 63 and the longitudinal slider 53 to check for alignment between the transverse adaptation notch 64, the longitudinal adaptation notch 55, and the roller. If at least one of the transverse adaptation notch 64 or the longitudinal adaptation notch 55 is misaligned with the roller, the position of the roller relative to the mounting base hole is deemed unqualified.
[0027] The rapid testing device of this application can quickly test the positional accuracy of clearance grooves and rollers relative to mounting base holes. It has the advantages of simple structure, convenient operation and high testing efficiency, and is particularly suitable for large-volume rapid testing applications.
