[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] Examples, such as Figures 1-4 As shown, the present invention provides a tooling for testing tapered rollers, including a testing template 1. The testing template 1 is provided with a plurality of triangular model openings 11 spaced apart along its length. The triangular model openings 11 are triangular prisms with their upper and lower ends penetrating the upper and lower surfaces of the testing template 1. The testing template 1 is inclinedly mounted on a movable tooling plate 2. A fixed tooling plate 3 is provided on the front side of the movable tooling plate 2. A rotating roller 4 is provided on the fixed tooling plate 3 near the testing template 1. The rotating roller 4 is provided with a plurality of annular grooves 41 corresponding one-to-one with the triangular model openings 11. Handwheels 42 are provided at both ends of the rotating roller 4. A support opening 31 is provided at the bottom of the fixed tooling plate 3 to movably cooperate with the lower part of the rotating roller 4. A set of hand-push moving components 5 are provided on both sides of the fixed tooling plate 3 and the movable tooling plate 2. The fixed tooling plate 3 and the movable tooling plate 2 can be mounted on a tooling testing table, below the overhead rotating roller and the movable tooling plate, leaving sufficient space for the rotation circumference of the rotating roller 4 and the discharge of the tapered rollers.

[0018] Specifically, the inclined surface of the triangular model opening 11 on the inspection template 1 matches the taper of the tapered rollers in the batch to be inspected. The annular groove 41 on the rotating roller 4 forms an inspection channel with the triangular model opening 11. The clamping opening between the rotating roller 4 and the inspection template 1 can support multiple tapered rollers to be inspected, and the tapered rollers are arranged in an orderly manner in the inspection channel. The probe of the ultrasonic detector can pass horizontally through the clamping opening where the tapered roller is located and contact the corresponding tapered roller workpiece. By rotating the handwheel 42, the tapered roller can be rolled, which facilitates the completion of appearance inspection and ultrasonic inspection. The clamping opening can be quickly opened by using the hand-push moving component 5, so that the tapered rollers in the clamping opening can be quickly discharged from their respective inspection channels. The moving fixture plate 2 can be quickly reset under the action of the spring 55 and maintain the splicing relationship with the fixed fixture plate 3 so as to inspect the remaining tapered rollers. This utility model has a reasonable design and simple structure. It eliminates the need to hand-hold the tapered rollers for inspection, which is beneficial to improving inspection efficiency and has strong practicality.

[0019] To improve the practicality of the hand-push moving assembly 5, the hand-push moving assembly 5 provided by this utility model includes a fixed seat 51 connected to the side of the fixed tooling plate 3 and a moving seat 52 connected to the side of the moving tooling plate 2. A guide shaft 53 is provided at the center of the fixed seat 51. The guide shaft 53 is axially movable with the moving seat 52. The guide shaft 53 extends toward the back of the moving tooling plate 2 and a fixing block 54 is provided at the end of the guide shaft 53. A spring 55 is provided between the fixing block 54 and the moving seat 52. A handle 56 is provided at the top of the moving seat 52. The right-angled surface of the fixed block 54 rests against the movable fixture plate 2, but the fixed block 54 is not directly connected to the movable seat 52. The relative positional relationship between the fixed block 54, the guide shaft 53, and the fixed seat 51 remains unchanged. When the lever 56 is pushed, the movable seat 52 can be retracted along with the movable fixture plate 2, opening the clamping opening between the detection template 1 and the rotating roller 4, allowing the tapered rollers in the clamping opening to be quickly discharged from their respective detection channels. The spring 55 has a tendency to reset. When the lever 56 is released, the spring 55 can push the movable seat 52 and the movable fixture plate 2 to be reattached to the fixed fixture plate 3, so that the clamping opening can stably clamp the tapered rollers to be tested.

[0020] To facilitate material discharge, the mating surfaces of the movable tooling plate 2 and the fixed tooling plate 3 provided by this utility model are inclined. After the movable tooling plate 2 and the fixed tooling plate 3 are separated by a certain distance by manual pushing, the tapered roller can slide out from the inclined position. The bottom of the movable tooling plate 2 is provided with a discharge port 23 that is the same as the bottom of the inclined surface. The discharge port 23 can be used to install a receiving structure so as to collect the workpieces after inspection in a centralized manner.

[0021] To improve the utilization rate of this device, the present invention provides a plate-shaped groove 21 on the movable tooling plate 2 for installing the test template 1. Both ends of the test template 1 are provided with mounting holes 12. The plate-shaped groove 21 has a certain depth to accommodate the installation of all test templates 1. The back sides of test templates 1 of different specifications are consistent, while the front side is provided with a triangular model opening 11 for testing. The specific specifications of the triangular model opening 11 match the specifications of the corresponding tapered roller to be tested. The stability of the test template 1 is ensured by the mating pressure between the groove surfaces and the self-weight of the test template 1 when installed in the plate-shaped groove 21. By inserting a mounting tool through the mounting holes 12, the current test template 1 can be quickly replaced with a test template 1 that matches the specifications of the tapered roller.

[0022] Furthermore, the fixed fixture plate 3 provided by this utility model has half-holes on both sides for supporting the two shaft ends of the rotating roller 4. Above the half-holes, a clamping plate 6 is provided for clamping the shaft ends of the rotating roller 4. The clamping plate 6 has a shaft connection hole 61 at the end away from the rotating roller 4. The shaft connection hole 61 is nested and engaged with the positioning tube 32 provided on the side of the fixed fixture. A quick-release spring rod 7 is provided on the outside of the positioning tube 32. The quick-release spring rod 7 can be quickly inserted into the positioning tube 32 to provide a limit on the outside of the shaft connection node between the positioning tube 32 and the clamping plate 6, so that the two clamping plates 6 have a fixed horizontal distance. By rotating the clamping plate 6, the hole at its bottom can be matched with the half-hole on the fixed fixture plate 3 to achieve clamping of the rotating roller 4. The rotating roller 4 can be quickly replaced according to the testing needs so that the specifications of its annular groove 41 match the specifications of the tapered roller to be tested.

[0023] In order to improve the quick-connect performance of the quick-release spring rod 7, the quick-release spring rod 7 provided by this utility model includes a main rod part 71, the main rod part 71 has a U-shaped structure and its two ends are provided with insert rod parts 72 extending toward the center of the positioning tube 32, and the insert rod parts 72 are provided with baffle parts 73. The main rod 71 is a rod structure capable of bending. The insertion rod 72 provides a mating node for insertion into the positioning tube 32. By bending the main rod 71, the ends of the two insertion rods 72 can be opened by a certain distance, allowing them to quickly leave their respective mating positioning tubes 32. Conversely, after the two insertion rods 72 are passively opened, they can enter the position to be inserted into the positioning tube 32. Releasing the main rod 71 allows the insertion rods to be inserted into the positioning tube 32. The baffle 73 provides axial limitation for the clamping plate 6, preventing the clamping plate 6 from leaving its clamping position. After the main rod 71 is installed in place, it can be flipped and locked onto the top of the fixing tooling plate 3. The top of the fixing tooling plate 3 can be provided with a slot that mates with the main rod 71 to enhance the clamping reliability of the main rod 71 on the clamping plate 6.

[0024] To facilitate inspection, this utility model provides a roller holding hopper 8 above the fixed tooling plate 3, which is parallel to the top cross-section of the annular groove 41. The roller holding hopper 8 can hold more workpieces than the number of annular grooves 41. After the previous batch of tapered rollers has been inspected, these rollers to be inspected can be moved to a position close to the annular groove 41, ensuring that all positions of the annular groove 41 have as many workpieces to be inspected as possible, and quickly completing the workpiece arrangement work without having to hold the workpieces one by one.

[0025] Furthermore, this invention provides a guide rail 22 on the top of the movable tooling plate 2 for slidingly mounting the ultrasonic testing device. The ultrasonic testing device can be effectively guided by the guide rail 22, allowing it to pass through all the testing channels in an orderly manner. The probe of the ultrasonic testing device can be pressed against the surface of the tapered roller located in the testing channel by hand for ultrasonic testing.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
