Technical Field

[0001] This utility model relates to the technical field of automotive automatic gear shifters, and in particular to a torque testing mechanism for an automotive automatic gear shifter linkage. Background Technology

[0002] For connecting rod torque testing during the assembly stage, the existing technology involves fixing the connecting rod with a mechanism, then placing a linear motion mechanism at the end of the connecting rod. The linear motion of this mechanism moves the connecting rod to test its torque. This testing method has obvious drawbacks:

[0003] One problem is that the force applied to the lever cannot always be perpendicular to the lever, making it impossible to accurately measure the magnitude of the force.

[0004] Secondly, it is impossible to test the relationship between the magnitude of the force and the angle of the lever.

[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a torque testing mechanism for the linkage of an automatic gear shifter in automobiles, making it more valuable for industrial applications. Utility Model Content

The output end of the reducer at the bottom is connected to the first synchronous pulley, the first synchronous pulley is connected to the second synchronous pulley via the synchronous belt, and the second synchronous pulley is installed at the bottom of the main shaft.

[0013] As a further improvement of this utility model, a photoelectric sensor is installed on the second synchronous pulley, and two slotted photoelectric sensors adapted to the photoelectric sensor are provided on the right side of the photoelectric sensor. The slotted photoelectric sensors are installed at the bottom of the connecting plate through a photoelectric bracket.

[0014] As a further improvement of this utility model, the spindle is mounted on the connecting plate through a bearing seat, and the top of the connecting plate is connected to the top plate above through several connecting columns.

[0015] As a further improvement of this utility model, the bottom of the second synchronous pulley is connected to the encoder below, and the encoder is mounted on the base plate through the encoder mounting bracket.

[0016] As a further improvement of this utility model, the crimping assembly includes a rotary cylinder mounted on the top plate and a product pressure head mounted on the rotary cylinder.

[0029] The first embodiment of this utility model:

[0030] like Figures 1-2 As shown, the automatic gear shifter linkage torque testing mechanism of this embodiment mainly includes a reducer 1, a base plate 4, a torque sensor 9, a main shaft 11, a rotary cylinder 14, a product fixing fixture 15, a product pressure head 16, a linkage actuating block 18, a top plate 19, and a servo motor 22.

[0031] The product fixing fixture 15 for placing product 17 is installed on the top plate 19, and the top plate 19 is connected to the bottom plate 4 below by a number of support columns 6.

[0032] The base plate 4 serves as the bottom support structure of the entire device. A reducer support 3 is installed on the left side of the base plate 4. A reducer 1 and a servo motor 22 connected to the reducer 1 are installed on the reducer support 3. The output end of the reducer 1 is connected to the bottom of the main shaft 11 through a synchronous belt assembly. The synchronous belt assembly includes a first synchronous pulley 2, a synchronous belt 5, and a second synchronous pulley 7. The output end of the reducer 1 is connected to the first synchronous pulley 2, and the first synchronous pulley 2 is connected to the second synchronous pulley 7 through the synchronous belt 5. The second synchronous pulley 7 is installed at the bottom of the main shaft 11.

[0033] The spindle 11 is mounted on the connecting plate 13 via the bearing seat 12, and the top of the connecting plate 13 is connected to the top plate 19 above it via several connecting columns.

[0034] A torque sensor 9 is installed on the top of the main shaft 11. The torque sensor 9 is connected to the bottom left side of the connecting block 10 above. A connecting rod actuating block 18 is installed on the top right side of the connecting block 10. The connecting block 10 is located below the top plate 19. A connecting rod actuating hole is opened on the top plate 19 for the connecting rod actuating block 18 to pass through. The top of the connecting rod actuating block 18 passes through the connecting rod actuating hole and continues to extend above the top plate 19 and is adapted to the product fixing fixture 15 on the left. The product fixing fixture 15 is used to place the first end of the product 17 (i.e., the shifter connecting rod). The second end of the product 17 is placed in the slot in the connecting rod actuating block 18, and the connecting rod actuating block 18 can rotate in the arc-shaped connecting rod actuating hole.

[0035] A pressing assembly is installed on the top plate 19 on the left side of the product fixing fixture 15. The pressing assembly includes a rotary cylinder 14 and a product pressing head 16 mounted on the rotary cylinder 14. The rotary cylinder 14 is mounted on the top plate 19 and located on the left side of the product fixing fixture 15. The product pressing head 16 is used to press the product 17 located in the product fixing fixture 15 from the top.

[0036] Among them, a pressure block with a certain elastic function, such as a rubber block or a silicone block, is installed at the bottom of the aforementioned product pressure head 16.

[0037] The bottom of the timing pulley 27 is connected to the encoder 20 below it. The encoder 20 is mounted on the base plate 4 through the encoder mounting bracket 21.

[0038] A photoelectric sensor is installed on the synchronous pulley 7. Two slotted photoelectric sensors 8 that are compatible with the photoelectric sensor are provided on the right side of the photoelectric sensor. The slotted photoelectric sensors 8 are installed at the bottom of the connecting plate 13 through a photoelectric bracket.

[0039] The second embodiment of this utility model:

[0040] like Figures 1-2As shown, the reducer 1 is cylindrical, with a shaft hole at the upper end for connecting the servo motor 22, and an output shaft at the lower end. The output shaft is connected to the first synchronous pulley 2, which is connected to the second synchronous pulley 7 on the main shaft 11 via the synchronous belt 7. The main shaft 11 is installed in the bearing housing 12 and fixed at both ends by snap rings. The bearing housing 12 is fixed on the connecting plate 13.

[0041] The synchronous pulley 7 is connected to the encoder 19 below, and the encoder 19 body is fixed on the encoder mounting base 20. The main shaft 11 is connected to the torque sensor 9 above, and the torque sensor 9 is connected to the connecting block 10 above. The connecting rod actuating block 18 is fixed on the connecting block 10.

[0042] The top plate 19 is connected to the bottom plate 4 via the support column 6. The rotary cylinder 14 and the product fixing fixture 15 are fixed on the top plate. The product pressure head 16 is fixed on the rotary cylinder 14. The product 17 is placed inside the product fixing fixture 15.

[0043] Brief description of the work process:

[0044] Product 17 is manually placed into product fixing fixture 15. Rotary cylinder 14 rotates, pressing product 17 firmly through product pressure head 16. Servo motor 22 drives synchronous pulley 2 through reducer 1, which in turn drives synchronous pulley 7 through synchronous belt 5, thereby rotating main shaft 11. Encoder 20 below monitors the rotation angle, and slotted photoelectric sensor 8 on the right limits the maximum and minimum rotation angles. The rotation of main shaft 11 drives connecting rod actuation block 18 to rotate, thereby actuating the product connecting rod. Torque sensor 9 above main shaft 11 measures the torque during the actuation process. By rotating the connecting rod through the rotating mechanism, the relationship between different angles and torque magnitudes can be accurately measured.

[0045] This invention uses a rotating mechanism to turn the connecting rod, ensuring that the force applied during rotation remains perpendicular to the connecting rod, thereby allowing the torque sensor within the rotating mechanism to accurately measure the magnitude of the torque.

[0046] This invention uses an encoder to monitor the torque at different rotation angles, providing a more intuitive test of the relationship between the force and the angle, and solving the problem of insufficient accuracy in vertical bending tests.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0048] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
