Technical Field
[0001] This utility model relates to the field of valve core manufacturing technology, and in particular to an outer ring vibration detection device. Background Technology
[0002] The valve core is a valve component that enables the valve body to perform basic functions such as directional control, pressure control, or flow control by moving its body. According to its shape, it can generally be divided into ball (ball valve), conical (plug valve), disc (butterfly valve and gate valve), round cover type (gate valve and check valve) and cylindrical (directional valve).
[0003] Currently, when producing directional valve cores, it is necessary to perform roundness testing on the ends of the cores to prevent excessive vibration of the core end face, which could affect the precision of the core and cause leakage at the connection between the core and the valve body. Utility Model Content

A double-output cylinder is rotatably connected to the top of the pad. Both ends of the double-output cylinder are provided with arc-shaped clamping plates. Arc-shaped rubber pads are provided on one side of each of the two arc-shaped clamping plates. The arc surfaces of the two arc-shaped clamping plates face each other. Two slots are opened on one side of each of the two arc-shaped clamping plates, and locking strips are slidably engaged inside the slots.
[0006] Optionally, multiple of the card strips are connected to each other with corresponding arc-shaped rubber pads, and a valve core body is provided between the opposite sides of two arc-shaped rubber pads.
[0007] Optionally, a motor is installed inside the pad, and the output end of the motor extends through to the top of the pad and is fixed to the bottom of the dual-output cylinder.
[0008] Optionally, the workbench has two cabinet doors on the front side, and a three-axis coordinate system is provided on the top of the workbench near the rear edge.
[0009] Optionally, a probe sensor is connected to the coordinate measuring machine, and the probe portion of the probe sensor is in contact with the end face of the valve core body.

[0013] 1. In this utility model, the arc surfaces of the two arc-shaped clamping plates are opposite each other, which facilitates the clamping of the valve core body by the two arc-shaped clamping plates when the dual output cylinder moves. During clamping, arc-shaped rubber pads are provided on both sides of the arc-shaped clamping plates to prevent the arc-shaped clamping plates from damaging the outer surface of the valve core body during the clamping process, thus affecting the precision of the valve core body. When the arc-shaped rubber pads and arc-shaped clamping plates are connected to each other, they are engaged by the locking strips and locking grooves, which facilitates the installation and disassembly of the arc-shaped rubber pads.
[0014] 2. In this utility model, a three-coordinate system is set on the platform, and the probe sensor is installed on the three-coordinate system. The three-coordinate system can drive the probe sensor to move in three-dimensional space, which makes it easy to attach the probe of the probe sensor to the end face of the valve core body. During detection, the motor is started to drive the dual-output cylinder to rotate, which will also drive the valve core body to rotate. In this way, the probe sensor can detect the vibration amplitude of the end face of the valve core body. Attached Figure Description

Detailed Implementation
[0022] The present invention will now be described in further detail with reference to the accompanying drawings.
[0023] Example 1, as Figure 1-3 As shown, this utility model provides a technical solution for an outer ring vibration detection device: it includes a workbench 1 and a table plate 2. The table plate 2 is fixed on the top of the workbench 1. A pad 8 is provided on the top of the table plate 2. A double-output cylinder 10 is rotatably connected to the top of the pad 8. Both ends of the double-output cylinder 10 are provided with arc-shaped clamping plates 11. Arc-shaped rubber pads 15 are provided on one side of each of the two arc-shaped clamping plates 11. The arc surfaces of the two arc-shaped clamping plates 11 are opposite to each other. Two slots 14 are opened on one side of each of the two arc-shaped clamping plates 11. The slots 14 are slidably engaged with locking strips 16.
[0024] The overall effect of Embodiment 1 is that the arc surfaces of the two arc-shaped clamping plates 11 are aligned, which facilitates the clamping of the valve core body 12 by the two arc-shaped clamping plates 11 when the dual output cylinder 10 moves. During clamping, arc-shaped rubber pads 15 are provided on both sides of the arc-shaped clamping plates 11 to prevent the arc-shaped clamping plates 11 from damaging the outer surface of the valve core body 12 during the clamping process, thus affecting the precision of the valve core body 12. When the arc-shaped rubber pads 15 are connected to the arc-shaped clamping plates 11, they are engaged by the locking strips 16 and the locking grooves 14, which facilitates the installation and removal of the arc-shaped rubber pads 15.
[0025] Example 2, as Figure 1-3 As shown, multiple card strips 16 are connected to each other with arc-shaped rubber pads 15. A valve core body 12 is provided between the opposite sides of two arc-shaped rubber pads 15. A motor 9 is provided inside the pad platform 8. The output end of the motor 9 extends through to the top of the pad platform 8 and is fixed to the bottom of the double-output cylinder 10. Two cabinet doors 3 are provided on the front side of the workbench 1. A three-coordinate 4 is provided on the top of the platform 2 near the rear edge. A probe sensor 13 is connected to the three-coordinate 4. The probe part of the probe sensor 13 is in contact with the end face of the valve core body 12. Pull-out grooves 5 are provided on the top of the platform 2 near the two side edges. Storage boxes 6 are slidably connected inside the two pull-out grooves 5. Multiple storage slots 7 are provided at equal intervals on the top of the two storage boxes 6.
[0026] The effect achieved by the entire embodiment 2 is that a coordinate measuring machine 4 is set on the platform 2, and the probe sensor 13 is installed on the coordinate measuring machine 4. The coordinate measuring machine 4 can drive the probe sensor 13 to move in three-dimensional space, which makes it easy to attach the probe of the probe sensor 13 to the end face of the valve core body 12. During detection, the motor 9 is started to drive the dual output cylinder 10 to rotate, which will also drive the valve core body 12 to rotate. In this way, the probe sensor 13 can detect the vibration amplitude of the end face of the valve core body 12.
[0027] Working principle: When using this device, the arc surfaces of the two arc-shaped clamping plates 11 are aligned to facilitate the clamping of the valve core body 12 by the two arc-shaped clamping plates 11 when the dual-output cylinder 10 moves. During clamping, arc-shaped rubber pads 15 are provided on both sides of the arc-shaped clamping plates 11 to prevent the arc-shaped clamping plates 11 from damaging the outer surface of the valve core body 12 during clamping, thus affecting the precision of the valve core body 12. When the arc-shaped rubber pads 15 are aligned with the arc-shaped clamping plates 11, they are connected by the locking strip 16 and the locking groove 14. The interlocking mechanism facilitates the installation and removal of the arc-shaped rubber pad 15. A coordinate measuring machine 4 is set on the platform 2, and the probe sensor 13 is mounted on the coordinate measuring machine 4. The coordinate measuring machine 4 can drive the probe sensor 13 to move in three-dimensional space, making it easy to attach the probe of the probe sensor 13 to the end face of the valve core body 12. During detection, the starter motor 9 drives the dual-output cylinder 10 to rotate, which also drives the valve core body 12 to rotate. In this way, the probe sensor 13 can detect the vibration amplitude of the end face of the valve core body 12.
