[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This utility model embodiment provides a conical pin vibration testing device, such as... Figure 1-4 As shown, the system includes a base 1, a support plate 5 on top of the base 1, several placement grooves on the top of the support plate 5, and the spacing between two adjacent placement grooves is the same. Fixing ears 3 are connected to the left and right sides of the support plate 5 near the center. Support rods 4 are connected to the top of the two fixing ears 3 on the side away from the center of the inner cavity of the support plate 5 near the center. Connecting ears 6 are fitted onto the top of the two support rods 4 near their ends. A positioning plate 7 is connected to the adjacent side of the two connecting ears 6. Several positioning grooves are opened at the bottom of the positioning plate 7, the spacing between two adjacent positioning grooves is the same, and the size of the positioning grooves is smaller than the size of the placement grooves. A vibration assembly 2 is located inside the cavity of the base 1. The vibration assembly 2 includes a turntable 21 located at the rear bottom of the cavity of the base 1. A rotating roller 210 is connected to the rear side of the turntable 21 near the center, and the rear end of the rotating roller 210 is movably connected to the rear inner wall of the base 1 near the bottom center.

[0022] It should be noted that, due to the poor detection efficiency and cumbersome fixing operation of the existing conical pin vibration testing device, in order to solve the problems encountered in the use of the existing conical pin vibration testing device, this solution solves the problems of poor detection efficiency and cumbersome fixing operation by adding a vibration component 2 to the inner cavity of the base 1 and using the cooperation of various components on the two fixing ears 3.

[0023] In a further preferred embodiment of this utility model, such as Figure 1 , 3 As shown in Figure 4, a rotating rod 29 is movably connected to the front side of the turntable 21 near the bottom center, and a cam 22 is connected to the front end of the rotating rod 29. A rotating shaft 26 is connected to the rear side of the cam 22 near the top center, and a drive plate 23 is movably connected to the rear end of the rotating shaft 26. A connecting rod 25 is connected to the top of the drive plate 23 near the center of the left and right sides, and the two connecting rods 25 are symmetrically arranged with the center of the inner cavity of the drive plate 23 as the axis of symmetry. A through hole is opened at the top of the base 1 near the center of the left and right sides. The top ends of the two connecting rods 25 penetrate the inner cavity of the adjacent through hole and are connected to the bottom of the support plate 5 near the center.

[0024] In this embodiment, when the operator uses the testing device to inspect the quality of the tapered pins, the operator first fixes several tapered pins to be inspected between the support plate 5 and the positioning plate 7. Then, the operator drives the rotating roller 210 to rotate. When the rotating roller 210 rotates, it drives the turntable 21 to rotate. This causes the turntable 21 to drive the cam 22 to move in a circular motion along with the turntable 21 via the rotating rod 29. This causes the cam 22 to move up and down reciprocally. When the cam 22 moves up and down reciprocally, it drives the drive plate 23 to move up and down reciprocally via the rotating shaft 26. This causes the drive plate 23 to drive the support plate 5 to move up and down reciprocally via the two connecting rods 25. The up and down movement of the support plate 5 drives the tapered pins fixed on its top to move up and down reciprocally. This allows the testing device to quickly vibrate the tapered pins to inspect their quality, thereby improving the testing efficiency of the testing device to a certain extent and facilitating practical use.

[0025] In a further preferred embodiment of this utility model, such as Figure 3 As shown, limit holes are provided in the inner cavity of the drive plate 23 near the center of the left and right sides. T-shaped limit rods 24 are movably connected to the inner cavity of the two limit holes. The two T-shaped limit rods 24 are symmetrically arranged with the center of the inner cavity of the drive plate 23 as the axis of symmetry. The narrower end of the T-shaped structure of the two T-shaped limit rods 24 passes through the inner cavity of the adjacent limit hole and is connected to the inner wall of the top of the base 1 near the center of the left and right sides, respectively.

[0026] In this embodiment, the drive plate 23 can slide on the two T-shaped limiting rods 24 when it moves up and down, thereby limiting the position of the drive plate 23 and allowing the drive plate 23 to move smoothly.

[0027] In a further preferred embodiment of this utility model, such as Figure 3 and 4 As shown, a driven bevel gear 211 is connected to the roller 210 near the rear end, and the rear side of the driven bevel gear 211 is movably connected to the inner wall of the rear side of the base 1 near the bottom center. There is a driving bevel gear 212 on the right front side of the driven bevel gear 211, and the driving bevel gear 212 meshes with the driven bevel gear 211. There is a drive motor 28 on the right side of the drive bevel gear 212, and the left end of the power output shaft of the drive motor 28 is connected to the right side of the drive bevel gear 212 near the center.

[0028] In this embodiment, the operator starts the drive motor 28 by connecting an external power source. When the drive motor 28 is powered on, it can quickly drive the drive bevel gear 212 to rotate. When the drive bevel gear 212 rotates, it meshes with the driven bevel gear 211, thereby driving the driven bevel gear 211 to rotate. In turn, the driven bevel gear 211 can quickly drive the turntable 21 to rotate via the rotating roller 210.

[0029] In a further preferred embodiment of this utility model, such as Figure 3 As shown, there is a fixing rod 27 on the right side of the drive motor 28. The left end of the fixing rod 27 is connected to the right side of the drive motor 28 near the center, and the right end of the fixing rod 27 is connected to the right inner wall of the base 1 near the bottom rear side.

[0030] In this embodiment, the drive motor 28 is fixed to the bottom right side of the inner cavity of the base 1 by the fixing rod 27, thereby limiting the position of the drive motor 28 and enabling the drive motor 28 to work stably.

[0031] In a further preferred embodiment of this utility model, such as Figure 1 and 2 As shown, the top of the two support rods 4 is provided with a top plate 8, and the bottom of the top plate 8 is connected to the top of the adjacent support rod 4 near the center of the left and right sides. The top of the top plate 8 is connected to the electric telescopic rod 9 near the center of the left and right sides. The two electric telescopic rods 9 are symmetrically arranged with the center of the inner cavity of the top plate 8 as the axis of symmetry. The inner cavity of the top plate 8 is provided with movable holes near the center of the left and right sides. The bottom ends of the two electric telescopic rods 9 pass through the adjacent movable inner cavity and are connected to the top of the positioning plate 7 near the center of the left and right sides.

[0032] In this embodiment, when the operator intends to fix the conical pin onto the testing device for testing, the operator first places the wider side of the conical pin into several placement grooves. Then, the operator activates two electric telescopic rods 9 via an external power source. The two electric telescopic rods 9 extend outwards while energized, causing the positioning plate 7 to move downwards. As the positioning plate 7 moves downwards, the two connecting ears 6 slide downwards on the two support rods 4, thus defining the position of the positioning plate 7. This allows the positioning plate 7 to move smoothly downwards, enabling the positioning grooves on the positioning plate 7 to quickly contact the tops of the conical pins placed in the several placement grooves. This quickly fixes the conical pin between the support plate 5 and the positioning plate 7, achieving the purpose of conveniently fixing the conical pin. This allows the operator to quickly fix the conical pin onto the device for testing, offering high flexibility and ease of operation.

[0033] In a further preferred embodiment of this utility model, such as Figure 1 As shown, the bottom of the base 1 is connected to several legs 10, and the legs 10 are arranged in a rectangular array with the center of the inner cavity of the base 1 as the axis of symmetry.

[0034] In this embodiment, by connecting four support legs 10 to the bottom of the base 1, it is convenient for workers to place the device stably on the ground of the work area for use.
