Description

Technical Field

[0001] This utility model relates to the field of automotive testing technology, specifically a device for testing the position of the 4-R gear shift fork in an automotive transmission. Background Technology

[0002] In the manufacturing process of automotive transmissions, the positional accuracy of the 4-R shift fork has a crucial impact on the transmission's performance and reliability. Deviations in the shift fork's position can lead to uneven shifting, poor gear meshing, and even transmission failure.

[0003] Traditional testing methods often have many drawbacks, such as difficulty in calibrating the reference, resulting in large measurement errors; unstable measurement process with poor repeatability; and low testing efficiency, making it difficult to meet the needs of large-scale production. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a device for testing the position of the 4-R gear shift fork in an automotive transmission, which solves the problem that traditional testing methods often result in large measurement errors due to difficulties in establishing the correct reference.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a device for testing the position accuracy of a 4-R gear shift fork in an automotive transmission, comprising: a base, a support platform fixedly connected to the top of the base, a longitudinal push clamp fixedly connected to the top of the support platform, a reference pin fixedly connected to the bottom of the longitudinal push clamp, and a reference sleeve fixedly connected to the top of the base; further comprising: a reference seat fixedly connected to the top of the base, a transverse push clamp fixedly connected to the top of the base, a fixed seat fixedly connected to the top of the base, a push rod slidably connected to the inner side of the fixed seat, a detection sleeve fixedly connected to the outer side of the push rod, a limit seat fixedly connected to the top of the base, a detection push plate slidably connected to the inner side of the limit seat, and a guide seat fixedly connected to the top of the base, with a detection limit plate slidably connected to the inner side of the guide seat; pushing the transverse push clamp causes its output end to press the product body against the reference seat, thereby achieving positioning based on this reference, reducing reference error and improving detection accuracy.

[0008] Preferably, the reference pin is located directly above the reference sleeve, the outer wall of the reference pin is slidably connected to the inner wall of the support platform, and the product body is movably installed between the reference pin and the reference sleeve. The outer side of the product body is in contact with the outer wall of the reference base. The product body is placed on the base so that it is positioned between the reference pin and the reference sleeve. Then, the longitudinal push clamp is pushed, and the longitudinal push clamp drives the reference pin to move downward, further fixing the product body in the longitudinal position.

[0009] Preferably, the outer side of the transverse pusher contacts the outer side of the product body, and the outer side of the product body contacts the inner side of the detection sleeve. By pushing the push rod, the detection sleeve slides within the fixed seat. If the detection sleeve moves smoothly, the relevant dimensions of the product body meet the requirements.

[0010] Preferably, the outer side of the detection push plate is in contact with the outer side of the product body, and the detection push plate is located between the transverse push clamp and the reference seat. The detection push plate is pushed to slide within the limit seat. If the detection push plate runs smoothly, the relevant dimensions of the product body meet the requirements.

[0011] Preferably, the outer side of the detection limiting plate is in contact with the outer side of the product body. The detection limiting plate is located on the side of the support platform near the fixed seat. Pushing the detection limiting plate to slide within the guide seat, if the detection limiting plate runs smoothly, then the relevant dimensions of the product body meet the requirements.

[0012] (III) Beneficial Effects

[0013] This utility model provides a device for testing the position accuracy of the 4-R gear shift fork in an automotive transmission. It has the following beneficial effects:

[0014] (i) The device uses a reference pin and a reference sleeve to push the longitudinal push clamp. The longitudinal push clamp moves the reference pin downward, further fixing the product body in the longitudinal position. Then, it pushes the transverse push clamp so that the output end of the transverse push clamp presses the product body against the reference seat. Positioning is performed using this reference, which reduces reference error and improves detection accuracy.

[0015] (II) This device pushes a push rod to slide the detection sleeve within the fixed seat, which in turn pushes the detection push plate within the limit seat. Simultaneously, it pushes the detection limit plate within the guide seat. If the detection sleeve, detection push plate, and detection limit plate all operate smoothly, then the dimensions of the relevant parts of the product body meet the requirements. By detecting from different directions using the detection sleeve, detection push plate, and detection limit plate, the device can comprehensively determine whether the position of the product body meets the relevant standards for the shift fork. This avoids the problems of poor reference alignment and unstable measurement process during direct measurement. The precise sliding of the guide rail greatly reduces the manufacturing error of the inspection tool itself and improves the accuracy of the detection. Attached Figure Description

[0023] 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.

[0024] Example: Please refer to Figure 1-6 This utility model provides a technical solution: a device for testing the position of a 4-R gear shift fork in an automotive transmission, comprising a base 1, a support platform 2 fixedly connected to the top of the base 1, a longitudinal push clamp 3 fixedly connected to the top of the support platform 2, a reference pin 4 fixedly connected to the bottom of the longitudinal push clamp 3, a reference sleeve 5 fixedly connected to the top of the base 1, and further comprising: a reference seat 6 fixedly connected to the top of the base 1, a transverse push clamp 7 fixedly connected to the top of the base 1, a fixed seat 8 fixedly connected to the top of the base 1, a push rod 9 slidably connected to the inner side of the fixed seat 8, a detection sleeve 10 fixedly connected to the outer side of the push rod 9, and a limiting seat 11 fixedly connected to the top of the base 1. A detection push plate 12 is slidably connected to the side, and a guide seat 13 is fixedly connected to the top of the base 1. A detection limiting plate 14 is slidably connected to the inner side of the guide seat 13. The reference pin 4 is located directly above the reference sleeve 5. The outer wall of the reference pin 4 is slidably connected to the inner wall of the support platform 2. The product body 15 is placed on the base 1, so that it is positioned between the reference pin 4 and the reference sleeve 5. Then, the longitudinal push clamp 3 is pushed, and the longitudinal push clamp 3 drives the reference pin 4 to move downward, further fixing the product body 15 in the longitudinal position. Then, the transverse push clamp 7 is pushed, so that the output end of the transverse push clamp 7 presses the product body 15 and the reference seat 6 together. Positioning is performed based on this reference, which reduces the reference error and improves the detection accuracy.

[0025] The product body 15 is movably installed between the reference pin 4 and the reference sleeve 5. The outer side of the product body 15 is in contact with the outer wall of the reference seat 6. The outer side of the transverse push clamp 7 is in contact with the outer side of the product body 15. The outer side of the product body 15 is in contact with the inner side of the detection sleeve 10. The outer side of the detection push plate 12 is in contact with the outer side of the product body 15. The detection push plate 12 is located between the transverse push clamp 7 and the reference seat 6. The outer side of the detection limit plate 14 is in contact with the outer side of the product body 15. The detection limit plate 14 is located on the side of the support platform 2 near the fixed seat 8. Pushing the push rod 9 causes the detection sleeve 10 to slide in the fixed seat 8. Then, pushing the detection push plate 12 slides in the limit seat 11. At the same time, pushing the detection limit plate 14 slides in the guide seat 13. If the detection sleeve 10, detection push plate 12, and detection limit plate 14 all operate smoothly. If the dimensions of the relevant parts of the product body 15 meet the requirements, the position of the product body 15 can be comprehensively judged from different directions by detecting the sleeve 10, the push plate 12, and the limit plate 14. This avoids the problem of poor reference alignment and unstable measurement process when directly measuring. The precision sliding of the guide rail greatly reduces the manufacturing error of the fixture itself and improves the accuracy of the detection.

[0026] Working principle: When in use, the product body 15 is placed on the base 1, so that it is positioned between the reference pin 4 and the reference sleeve 5. Then, the longitudinal push clamp 3 is pushed, which drives the reference pin 4 to move downward along the inner wall of the support platform 2, further fixing the product body 15 in the longitudinal position. Then, the transverse push clamp 7 is pushed, so that the output end of the transverse push clamp 7 presses the product body 15 and the reference base 6 together. Positioning is performed based on this reference, which reduces the reference error and improves the detection accuracy.

[0027] Subsequently, by pushing the push rod 9, the detection sleeve 10 slides within the fixed seat 8, and then the detection push plate 12 slides within the limiting seat 11. Simultaneously, the stepped detection limiting plate 14 slides within the guide seat 13. If the detection sleeve 10, detection push plate 12, and detection limiting plate 14 all operate smoothly, and the first step of the detection limiting plate 14 passes through the product body 15, while the second step is blocked when it contacts the product body 15, then the relevant dimensions of the product body 15 meet the requirements. By detecting from different directions using the detection sleeve 10, detection push plate 12, and detection limiting plate 14, it is possible to comprehensively determine whether the position of the product body 15 meets the relevant standards of the shift fork. This avoids the problems of poor reference alignment and unstable measurement process during direct measurement. The precision sliding of the guide rail greatly reduces the manufacturing error of the inspection tool itself and improves the accuracy of the inspection.
