Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to a convenient three-axis vibration sensor fixing tool for a production line. Background Art

[0002] At present, vibration sensors have many installation methods, such as handheld probe, beeswax, double-sided tape, magnetic base, gluing and bolt connection. Different installation methods correspond to different installation stiffness, so the natural frequency of the entire vibration sensor will be different. The greater the installation stiffness, the higher the natural frequency of the vibration sensor, and the higher the frequency band that can be used for measurement.

[0003] When testing the electric control column motor, the frequency band required for the measurement is relatively high. At present, the bolt connection installation method with the largest rigidity is generally selected to meet the higher measurement frequency band requirements. However, the bolt connection installation method is a lossy installation method, which requires opening threaded holes on the surface of the electric control column motor, which will cause a certain degree of damage to the electric control column motor.

[0004] Therefore, it is necessary to design a convenient three-axis vibration sensor fixing tool for the production line to ensure a firm and stable connection without damaging the dedicated motor for the electric control column, so as to meet the requirements of a higher measurement frequency band. Summary of the invention

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a convenient three-axis vibration sensor fixing tooling for a production line, which ensures a firm and stable connection without damaging the dedicated motor for the electric adjustment pipe column, thereby meeting the requirements of a higher measurement frequency band.

[0006] In order to achieve the above-mentioned purpose, the utility model is a convenient three-axis vibration sensor fixing tool for a production line, comprising a knob screw, an external connecting block, an internal connecting block, a three-axis vibration sensor, and a special motor for an electric adjustment column. The external connecting block is sleeved on the outside of the internal connecting block and the special motor for the electric adjustment column, the internal connecting block is slidably connected to the external connecting block, the internal connecting block is sleeved on the outside of the three-axis vibration sensor, and the internal connecting block is fixed to the three-axis vibration sensor, after the end of the knob screw passes through the external connecting block, it is connected to the inner block screw at the end of the inner connecting block, the end of the knob screw is threadedly connected to the external connecting block, and the three-axis vibration sensor is in contact with or separated from the special motor for the electric adjustment column.

[0007] The inner connection block and the triaxial vibration sensor are fixed with sensor screws.

[0008] The external connection block is provided with a through hole at a position corresponding to the sensor screw.

[0009] The inner connecting block is located in the mounting groove of the outer connecting block.

[0010] The inner connecting block is a contoured structure of a three-axis vibration sensor.

[0011] The external connection block is a contoured structure of the electric control column dedicated motor, and a gap is provided between the external connection block and the electric control column dedicated motor.

[0012] A gap is provided between the inner block screw and the screw hole of the inner connecting block.

[0013] Compared with the prior art, the utility model fixes and disassembles the three-axis vibration sensor and the electric adjustment column special motor by rotating the knob screw. The operation is simple and convenient, and there is no need to damage the electric adjustment column special motor to achieve a firm and stable connection, meeting the requirements of a higher measurement frequency band.

[0017] The utility model is now further described with reference to the accompanying drawings.

[0018] See also Figure 1 , Figure 2 and Figure 3 The utility model is a convenient three-axis vibration sensor fixing tool for production lines, including a knob screw, an external connection block, an internal connection block, a three-axis vibration sensor, and a special motor for electric adjustment column. The external connection block 1 is sleeved on the outside of the internal connection block 2 and the special motor 7 for electric adjustment column. The internal connection block 2 is slidably connected to the external connection block 1. The internal connection block 2 is sleeved on the outside of the three-axis vibration sensor 5, and the internal connection block 2 is fixed to the three-axis vibration sensor 5 to ensure a stable connection. After the end of the knob screw 3 passes through the external connection block 1, it is connected to the internal block screw 4 at the end of the internal connection block 2. The end of the knob screw 3 is threadedly connected to the external connection block 1, and the three-axis vibration sensor 5 is in contact with or separated from the special motor 7 for electric adjustment column.

[0019] The inner connection block 2 is fixed to the triaxial vibration sensor 5 by a sensor screw 6. The outer connection block 1 is provided with a through hole 11 at a position corresponding to the sensor screw 6, so as to facilitate adjustment of the sensor screw 6.

[0020] The inner connecting block 2 is located in the mounting groove of the outer connecting block 1, so that the inner connecting block 2 can slide up and down easily.

[0021] The inner connecting block 2 is a conformal structure of the three-axis vibration sensor 5, and the outer connecting block 1 is a conformal structure of the electric adjustment column dedicated motor 7. A gap is provided between the outer connecting block 1 and the electric adjustment column dedicated motor 7 to ensure that the knob screw 3 can drive the three-axis vibration sensor 5 to be pressed onto the electric adjustment column dedicated motor 7.

[0022] A gap is provided between the inner block screw 4 and the screw hole of the inner connection block 2 to ensure that the inner connection block 2 can be smoothly driven to move when the knob screw 3 is turned.

[0023] When the utility model is working, rotating the knob screw 3 can drive the inner connection block 2 and the three-axis vibration sensor 5 to slide downward in the installation groove of the outer connection block 1, so that the three-axis vibration sensor 5 is pressed against the electric adjustment column dedicated motor 7 for testing. After the test is completed, the knob screw 3 is rotated in the opposite direction to drive the inner connection block 2 and the three-axis vibration sensor 5 to slide upward in the installation groove of the outer connection block 1, so that the three-axis vibration sensor 5 is separated from the electric adjustment column dedicated motor 7.

[0024] The utility model realizes the fixing and disassembly of the three-axis vibration sensor and the electric adjustment column dedicated motor by rotating the knob screw. The operation is simple and convenient, and the electric adjustment column dedicated motor does not need to be damaged, so a firm and stable connection can be achieved, meeting the requirements of a higher measurement frequency band. The utility model can be applied to the production line of industrial automation, especially when the test product has displacement changes during the test process.
