Description

Technical Field

[0001] This utility model relates to the field of one-way clutch technology, and in particular to an automatic torque detection device for one-way clutches. Background Technology

[0002] One-way clutches are widely used in automotive transmissions, construction machinery, and other fields. The torque performance of their built-in rollers directly determines the stability of the transmission system, requiring high-precision testing before leaving the factory. Currently, the industry mostly uses semi-automated or manually assisted testing. Existing methods have low material loading efficiency, relying on manual placement of each piece, resulting in high labor costs and difficulty in matching production line capacity. Manual pushing is prone to workpiece misalignment and inaccurate center hole alignment, causing deviations in testing data. Front and back identification relies on manual labor, which is time-consuming, error-prone, and may even damage testing components due to reverse installation. Fourthly, the testing continuity is insufficient, lacking stable load-bearing and precise transfer mechanisms, making workpiece transfer prone to shaking and misalignment, leading to process interruptions. Utility Model Content

[0003] The present invention aims to solve the above-mentioned defects and provide an automatic torque detection device for a one-way clutch.

[0004] To overcome the deficiencies in the background technology, the technical solution adopted by this utility model to solve its technical problem is: an automatic torque detection device for a one-way clutch, comprising a rectangular plate, a bearing mechanism for stably supporting the one-way clutch to be tested, a reciprocating moving mechanism for driving the one-way clutch on the bearing mechanism to repeatedly move forward according to a set displacement, a conveying mechanism for continuously feeding and conveying the one-way clutch, a pushing mechanism for accurately pushing the one-way clutches on the conveying mechanism one by one to the bearing mechanism, a positive and negative detection mechanism for identifying and judging the positive and negative sides of the one-way clutch, and a torque detection mechanism for detecting the torque of the internal rollers of the one-way clutch.

[0005] Further modifications include the provision of two active discharge mechanisms on the rectangular plate, used to accurately remove one-way clutches that fail torque detection and one-way clutches that are determined to be facing upwards from the bearing mechanism.

[0006] Further modifications include the following: the forward / reverse detection mechanism includes a first bearing unit, a first lifting unit disposed on the first bearing unit, and a first rotary drive unit mounted on the first lifting unit. The first rotary drive unit is connected to the upper end of the first spindle assembly. A fixed cylinder is vertically mounted on the first lifting unit. The first spindle assembly is coaxially rotatably connected inside the fixed cylinder. A movable cylinder is coaxially slidably connected to the outer periphery of the fixed cylinder. The movable cylinder is rotatably connected to the rotary pressure cylinder. A rotating block corresponding to and coaxially distributed with the rotary pressure cylinder is rotatably disposed on the bearing mechanism. A compression spring for continuously pushing the movable cylinder downward is sleeved on the fixed cylinder. A counting plate is disposed on the rotary pressure cylinder. A sensing counting unit is disposed on the first lifting unit. The forward / reverse side of the one-way clutch is determined by detecting the rotation speed of the counting plate through the sensing counting unit.

[0007] Further modifications include the inductive counting unit including a bracket and a contact switch mounted on the bracket, the contact switch contacting a plurality of radially protruding protrusions equidistantly constructed on the outer periphery of the counting plate.

[0008] Further modifications include the torque detection mechanism comprising a second bearing unit, a second lifting unit mounted on the second bearing unit, and a mounting cylinder vertically mounted on a rectangular plate. A pressure plate assembly coaxially distributed with the mounting cylinder is vertically rotatably mounted on the second lifting unit. A rotating cylinder is coaxially rotatably mounted inside the mounting cylinder. A second rotation drive unit for driving the rotating cylinder to rotate is mounted on the rectangular plate. An end cap assembly is connected to the upper end of the rotating cylinder, and an inner spindle is coaxially rotatably mounted inside it. The lower end of the inner spindle is connected to a torque sensor. The torque sensor is mounted on a bracket assembly mounted on the rectangular plate. A movable ring and a return spring are provided in the inner cavity of the end cap assembly. The lower end of the return spring abuts against the inner bottom surface of the end cap assembly, and the upper end abuts against the lower end surface of the movable ring.

[0009] The beneficial effects of this utility model are as follows: This design adopts fully automated operation, the conveying mechanism realizes continuous feeding, the pushing mechanism accurately moves materials, and the reciprocating moving mechanism stably transports materials. No manual intervention is required, which greatly improves the detection efficiency and adapts to the production line capacity requirements. The positive and negative detection mechanism automatically judges the workpiece posture, avoiding the time-consuming and error-prone manual identification, while preventing damage to the detection components due to reverse installation. The torque detection mechanism directly collects the torque data of the built-in roller, ensuring workpiece stability, reducing detection deviation, and ensuring data reliability.

Detailed Implementation

[0012] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort in accordance with the embodiments of the basic utility model are within the scope of protection of this utility model.

[0013] refer to Figure 1 and Figure 2As shown, an automatic torque detection device for one-way clutches includes a rectangular plate 8, on which a supporting mechanism 6 is mounted for stably supporting the one-way clutches 9 to be tested; a reciprocating moving mechanism 7 for driving the one-way clutches 9 on the supporting mechanism 6 to repeatedly move forward according to a set displacement; a conveying mechanism 1 for continuously feeding and conveying the one-way clutches 9; a pushing mechanism 2 for accurately pushing the one-way clutches 9 on the conveying mechanism 1 one by one onto the supporting mechanism 6; a front / back detection mechanism 3 for identifying and determining the front and back of the one-way clutches 9; and a torque detection mechanism 5 for detecting the torque of the internal rollers of the one-way clutches 9. This design enables continuous automated detection of the one-way clutches 9, ensuring both the accuracy of torque detection and the final output torque of the one-way clutches 9 is qualified.

[0014] In a specific embodiment, the rectangular plate 8 is provided with two active discharge mechanisms 4, which are used to accurately remove one-way clutches 9 that fail torque detection on the bearing mechanism 6, as well as one-way clutches 9 that are determined to be facing upwards, so as to achieve the classification and discharge of unqualified workpieces and workpieces with abnormal posture.

[0015] In a specific embodiment, refer to Figure 3 , Figure 4 and Figure 5 As shown, the forward and reverse detection mechanism 3 includes a first supporting unit 301, a first lifting unit 302 disposed on the first supporting unit 301, and a first rotary drive unit 303 mounted on the first lifting unit 302. The first lifting unit 302 is used to drive the first rotary drive unit 303 to move up and down. The first rotary drive unit 303 is connected to the upper end of the first spindle assembly 310 and is used to drive the first spindle assembly 310 to rotate. A fixed cylinder 311 is vertically mounted on the first lifting unit 302, and the first spindle assembly 310 is coaxially rotatably connected inside the fixed cylinder 311. A movable cylinder 309 is slidably connected to the outer periphery of a fixed cylinder 311. The movable cylinder 309 is rotatably connected to a rotating pressure cylinder 306. A rotating block 308 corresponding to and coaxially distributed with the rotating pressure cylinder 306 is rotatably mounted on the bearing mechanism 6. A compression spring 304 for continuously pushing the movable cylinder 309 downward is sleeved on the fixed cylinder 311. A counting plate 305 is provided on the rotating pressure cylinder 306. A sensing counting unit 307 is provided on the first lifting unit 302. The rotation speed of the counting plate 305 is detected by the sensing counting unit 307 to determine the positive and negative sides of the one-way clutch 9.

[0016] Its working process is as follows: When the one-way clutch 9 moves onto the rotating block 308, the first lifting unit 302 drives the first spindle assembly 310, the fixed cylinder 311, the moving cylinder 309, and the rotating pressure cylinder 306 to move downwards together. During this process, the rotating pressure cylinder 306 first contacts the surface of the one-way clutch 9, and then the lower end of the first spindle assembly 310 inserts into the center hole of the one-way clutch 9 and contacts the internal rollers; afterwards, the first rotation drive unit 303 drives the first spindle assembly 310 to rotate counterclockwise. When the first spindle assembly 310 is the front side, it will drive the one-way clutch 9, the rotating pressure cylinder 306 and the rotating block 308 to rotate synchronously, and the counting plate 305 will also rotate synchronously with it. At this time, the sensing counting unit 307 calculates the rotation speed of the counting plate 305. When the rotation speed reaches the preset speed, the workpiece is confirmed to be the front side. If the one-way clutch 9 is the back side, the rotating block 308, the rotating pressure cylinder 306 and the counting plate 305 will not rotate synchronously with the first spindle assembly 310, and the rotation speed will not reach the preset speed, thus it is determined to be the back side.

[0017] In a specific embodiment, the inductive counting unit 307 includes a bracket and a contact switch mounted on the bracket. The contact switch contacts a plurality of radially protruding protrusions equidistantly constructed on the outer periphery of the counting plate 305. The rotational speed is calculated by detecting the contact frequency between the contact switch and the protrusions.

[0018] In a specific embodiment, refer to Figure 6 , Figure 7 and Figure 8 As shown, the torque detection mechanism 5 includes a second bearing unit 501, a second lifting unit 502 disposed on the second bearing unit 501, and a mounting cylinder 505 vertically disposed on the rectangular plate 8. A pressure plate assembly 509, coaxially distributed with the mounting cylinder 505, is vertically rotatably disposed on the second lifting unit 502. Its function is to press against the upper end face of the one-way clutch 9 to ensure stable positioning of the workpiece during detection. A rotating cylinder 511 is coaxially rotatably disposed inside the mounting cylinder 505. A second rotation drive unit 508 is disposed on the rectangular plate 8 to drive the rotating cylinder 511 to rotate. An end cap is connected to the upper end of the rotating cylinder 511. Component 504 has an internal coaxially rotating inner spindle 510. The lower end of the inner spindle 510 is connected to a torque sensor 512. The torque sensor 512 is mounted on a bracket assembly 503 on a rectangular plate 8 to collect torque signals. The inner cavity of the end cover assembly 504 is provided with a movable ring 506 and a return spring 507 that can move up and down. The lower end of the return spring 507 abuts against the inner bottom surface of the end cover assembly 504, and the upper end abuts against the lower end surface of the movable ring 506. The return spring 507 pushes the upper end surface of the movable ring 506 to be flush with the upper end surface of the end cover assembly 504, providing a flat support surface for the placement of the one-way clutch 9.

[0019] Its working process is as follows: when the reciprocating moving mechanism 7 moves the one-way clutch 9 onto the moving ring 506, the second lifting unit 502 drives the pressure plate assembly 509 to move down, indirectly pushing the moving ring 506 to make the one-way clutch 9 embedded in the inner cavity of the end cover assembly 504. During this process, the return spring 507 is gradually compressed; at the same time, the upper end of the inner spindle 510 is simultaneously inserted into the center hole of the one-way clutch 9 and contacts the roller.

[0020] When the second rotary drive unit 508 drives the rotary cylinder 511 to rotate, the end cover assembly 504, the moving ring 506 and the one-way clutch 9 rotate synchronously. The one-way clutch 9 then drives the inner spindle 510 to rotate. At this time, the torque sensor 512 detects the torque of the one-way clutch 9 acting on the inner spindle 510.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
