Description

Technical Field

[0001] The utility model relates to the technical field of spherical surface measuring devices, in particular to a spherical surface measuring device for a ball valve. Background Art

[0002] Ball valves can be divided into aluminum alloy, stainless steel, copper, etc. The key component of the ball valve is the ball valve valve, and the surface roughness after processing needs to be strictly controlled. When processing the ball valve valve, it is necessary to use three-coordinate measurement to measure its sphericity many times. The three-coordinate measurement has the disadvantages of high measurement cost, low conversion efficiency and long measurement cycle, so it is necessary to use a spherical measurement device to measure the surface roughness of the ball.

[0003] When processing the ball valve, a spherical surface measuring device is needed. Among them, the "simple stylus dial indicator type differential housing internal spherical coaxiality measuring device" disclosed in the application number "CN207894358U" has solved the various disadvantages of the three-dimensional coordinate measuring instrument, which has very strict requirements on the environment and temperature of the workplace, and its measurement efficiency and the response time of the measurement results cannot reach the production site in a timely and accurate manner, and the operation is cumbersome and requires high operating skills.

[0004] However, when using a spherical measuring device with a similar structure in practice, there are still many defects, such as: it does not have the function of detecting ball valve balls of different specifications, the device is easily restricted by the specifications of the ball valve ball, and it is also unable to detect the edge position of the ball valve ball. The operator is required to manually rotate the ball valve ball, which reduces the convenience of using the device. At the same time, it does not have the function of improving the monitoring accuracy of the ball valve ball. The operator's handheld device is prone to position deviation, which reduces the reliability of the device. Therefore, it is necessary to design a ball valve valve spherical surface measuring device. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a device for measuring the spherical surface of a ball valve to solve the above problems.

[0006] To achieve the above purpose, the utility model is implemented through the following technical solutions: a ball valve valve spherical surface measuring device, including a lever dial gauge body, an adaptive mechanism for clamping the ball valve spherical surface of the ball valve is movably installed on the outer side of the lever dial gauge body, and an adjustment mechanism for adjusting the installation state of the device is fixedly installed on the top of the lever dial gauge body;

[0007] The adaptive mechanism comprises a clamping arm, a tension piece is fixedly mounted on one side of the clamping arm, and one side of the tension piece is fixedly connected to one side of the lever dial indicator body, a mounting seat is fixedly mounted on one end of the clamping arm, a servo motor is fixedly mounted on one side of the mounting seat, and a resistance ball is fixedly mounted on the output end of the servo motor;

[0008] The adjusting mechanism comprises a connecting frame, and a level sensor is installed at the top height of the connecting frame.

[0009] Preferably, an indicator is fixedly mounted on the top of the front side of the lever dial indicator body, and a pointer is rotatably mounted inside the indicator.

[0010] Preferably, two groups of electric rods are fixedly installed on both sides of the connecting frame, and a contact foot is fixedly installed on the output end of the electric rod.

[0011] Preferably, two sets of shaft frames are fixedly installed on the outer side of the lever dial indicator body, and one side of the shaft frame is movably connected to one end of the clamping arm.

[0013] Preferably, a hinge is fixedly mounted on one side of the back side of the lever dial indicator body, and a box cover is fixedly mounted on one side of the hinge.

[0014] Beneficial Effects

[0015] The utility model provides a device for measuring the spherical surface of a ball valve. Compared with the prior art, it has the following beneficial effects:

[0016] 1. By pulling the clamping arm to move the position, the moving clamping arm can drive the tension piece to elastically expand and contract, so that the mounting seat can be relatively expanded, and the high elastic force of the tension piece can drive the mounting seat to move to the outside of the ball surface of the valve of the ball valve to be measured, and then the servo motor can be powered on to drive the resistance ball to rotate. The rotating resistance ball can be conveniently used to adjust the position of the valve ball of the ball valve to be measured, thereby realizing the function of detecting valve balls of ball valves of different specifications, avoiding the device being limited by the specifications of the valve ball of the ball valve, and also facilitating the detection of the edge position of the valve ball of the ball valve, thereby increasing the convenience of using the device.

[0017] 2. The horizontal state of the device can be monitored in real time by energizing the horizontal sensor, and the contact feet can be controlled by wires to move the vertical position of multiple sets of electric rods. The horizontal state of the connecting frame installation can be adjusted by the contact feet that move the vertical position. The connecting frame that moves the position can drive the lever dial indicator body to adjust the position synchronously, so that the lever dial indicator body is in a horizontal state, thereby realizing the function of improving the monitoring accuracy of the ball valve valve ball, avoiding the problem of position deviation of the operator's handheld device, and ensuring the reliable effect of using the device.
