Description

[0002] In recent years, with the development of intelligent manufacturing, higher requirements have been placed on the quality and efficiency of mechanical manufacturing. Vibration detection during processing is irreplaceable. Vibration during processing generally comes from tool wear, equipment resonance, and material vibration. In the processing of aerospace parts and other precision parts, excessive vibration seriously reduces processing efficiency and increases processing costs.

[0003] There are two methods of monitoring in traditional processing: direct monitoring and indirect monitoring. For example, the machine vision method and the radiation method are both direct monitoring methods, but both have fatal shortcomings. The former has extremely high requirements for the camera and is easily affected by the cutting fluid and light; the latter detects by adding radioactive substances, but causes harm to the operator's environment. The production of cutting tools is complicated. The temperature method is an indirect monitoring method that detects tool damage by monitoring the temperature of the tool during processing. However, the tool, workpiece material, chip removal and the use of cutting fluid during the processing process will affect the accuracy of the collected temperature signal. Utility Model Content

[0024] like Figure 1-3As shown, an embodiment of the utility model provides a vise-based vibration detection device, which includes: a shell 1, a vibration connecting member 2, an X-axis vibration detection member 3, a Y-axis vibration detection member 4, and a Z-axis vibration detection member 5, wherein the vibration connecting member 2 is passed through the shell 1, and one end located outside the shell 1 forms a vibration detection end in contact with a workpiece; the X-axis vibration detection member 3 is arranged in the shell 1 along the X-axis direction and is fixed to the vibration connecting member 2, for detecting vibrations in the X-axis direction; the Y-axis vibration detection member 4 is arranged in the shell 1 along the Y-axis direction and is fixed to the vibration connecting member 2, for detecting vibrations in the Y-axis direction; the Z-axis vibration detection member 5 is arranged in the shell 1 along the Z-axis direction and is fixed to the vibration connecting member 2, for detecting vibrations in the Z-axis direction.

[0025] The utility model proposes a vise-based vibration detection device, which includes a shell 1, a vibration connection member 2, an X-axis vibration detection member 3, a Y-axis vibration detection member 4, and a Z-axis vibration detection member 5. The vibration connection member 2 is inserted into the shell 1, and one end outside the shell 1 forms a vibration detection end in contact with the workpiece being processed; the X-axis vibration detection member 3 is arranged in the shell 1 along the X-axis direction and fixed to the vibration connection member 2, and is used to detect vibrations in the X-axis direction; the Y-axis vibration detection member 4 is arranged in the shell 1 along the Y-axis direction and fixed to the vibration connection member 2, and is used to detect vibrations in the Y-axis direction; the Z-axis vibration detection member 5 is arranged in the shell 1 along the Z-axis direction and fixed to the vibration connection member 2, and is used to detect vibrations in the Z-axis direction. This vise-based vibration detection device uses an indirect monitoring method to detect the vibration of the workpiece, which can realize online monitoring and detection of the vibration of the workpiece during the processing process, and is not easily affected by other factors and has high stability.

[0026] Specifically, the housing 1 includes an inner shell 11 and an outer cover 12. The bottom of the inner shell 11 has an abutting surface that abuts against the vise. The top of the outer cover 12 is fixed to the outer surface of the inner shell 11. The bottom of the outer cover 12 is spaced apart from the inner shell 11 and forms a fixed end fixed to the vise. The purpose of this design is that the outer shell adopts a double-layer seal at the bottom to prevent the chip liquid from penetrating during processing, and also creates a sealed environment for the internal structure, greatly reducing external interference, making the internal equipment measurement more accurate, and also preventing damage to the internal structure during processing, so as to protect the internal components to the maximum extent.

[0027] Furthermore, a slanted surface is formed at the connection between the top of the outer cover 12 and the inner shell 11 for drainage.

[0028] Furthermore, bolt seats 121 are formed on both sides of the outer cover 12, and the bolt seats 121 are fixed to the vise by bolts.

[0029] Specifically, the vibration connecting member 2 includes a vibration transmission rod 21 and a vibration block 22. The vibration transmission rod 21 is inserted into the housing 1. One end of the vibration transmission rod 21 located outside the housing 1 forms the vibration detection end. One end of the vibration transmission rod 21 located inside the housing 1 is fixed to the vibration block 22. The X-axis vibration detection member 3, the Y-axis vibration detection member 4, and the Z-axis vibration detection member 5 are fixed to the vibration block 22. When in use, the vibration transmission rod 21 contacts the workpiece and transmits the vibration of the workpiece to the vibration block 22. The X-axis vibration detection member 3, the Y-axis vibration detection member 4, and the Z-axis vibration detection member 5 respectively detect the vibration of the vibration block 22 on the X-axis, Y-axis, and Z-axis to determine the vibration of the workpiece.

[0030] Furthermore, a shock-absorbing seal ring 211 is sleeved on the vibration transmission rod 21, and the shock-absorbing seal ring 211 is fixed to the housing 1. The function of the shock-absorbing seal ring 211 is to reduce the interference of the vibration of the housing 1 on the vibration transmission rod 21. The housing 1 is not rigidly connected with the vibration connection member 2, the X-axis vibration detection member 3, the Y-axis vibration detection member 4, and the Z-axis vibration detection member 5, so that the vibration of the housing 1 cannot interfere with the X-axis vibration detection member 3, the Y-axis vibration detection member 4, and the Z-axis vibration detection member 5.

[0031] Furthermore, the vibration transmission rod 21 and the vibration block 22 are made of tungsten alloy, which can transmit the vibration frequency more clearly, thus facilitating detection.

[0032] Furthermore, a damping sheet 221 is attached to the bottom of the vibration block 22 to reduce interference caused by the vibration of the machine tool.

[0033] Furthermore, the X-axis vibration detection component 3 includes an X-axis vibration amplifying plate 31 and an X-axis vibration sensor 32. The X-axis vibration amplifying plate 31 is arranged along the X-axis direction, one end of the X-axis vibration amplifying plate 31 is fixed to the vibration connecting component 2, and the X-axis vibration sensor 32 is fixed on one end of the X-axis vibration amplifying plate 31 away from the vibration connecting component 2.

[0034] Furthermore, in order to make the X-axis vibration sensor 32 of low-frequency vibration receive signals better, the X-axis vibration amplifier plate 31 is made of steel sheet. When the length of the X-axis vibration amplifier plate 31 is 17.6mm and the thickness is 9.6mm, it can rely on its own performance advantages to maximize the transmission of vibration from the tail to the head. And we choose steel with less damping and greater elasticity as the vibration amplifier plate, and increase the vibration transmission by changing its own size and shape.

[0035] Furthermore, the Y-axis vibration detection component 4 includes a Y-axis vibration amplifying plate 41 and a Y-axis vibration sensor 42. The Y-axis vibration amplifying plate 41 is arranged along the Y-axis direction, one end of the Y-axis vibration amplifying plate 41 is fixed to the vibration connecting component 2, and the Y-axis vibration sensor 42 is fixed on the end of the Y-axis vibration amplifying plate 41 away from the vibration connecting component 2.

[0036] Furthermore, in order to make the Y-axis vibration sensor 42 with low-frequency vibration receive signals better, the Y-axis vibration amplifier plate 41 is made of steel sheet. When the length of the Y-axis vibration amplifier plate 41 is 17.6mm and the thickness is 9.6mm, it can rely on its own performance advantages to maximize the transmission of vibration from the tail to the head. And we choose steel with less damping and greater elasticity as the vibration amplifier plate, and increase the vibration transmission by changing its size and shape.

[0037] Furthermore, the Z-axis vibration detection component 5 includes a Z-axis vibration amplifying plate 51 and a Z-axis vibration sensor 52. The Z-axis vibration amplifying plate 51 is arranged along the Z-axis direction, one end of the Z-axis vibration amplifying plate 51 is fixed to the vibration connecting component 2, and the Z-axis vibration sensor 52 is fixed on the end of the Z-axis vibration amplifying plate 51 away from the vibration connecting component 2.

[0038] Furthermore, in order to make the Z-axis vibration sensor 52 with low frequency vibration receive signals better, the Z-axis vibration amplifier plate 51 is made of steel sheet. When the Z-axis vibration amplifier plate 51 is 17.6mm in length and 9.6mm in thickness, it can maximize the transmission of vibration from the tail to the head by relying on its own performance advantages. And we select steel with less damping and greater elasticity as the vibration amplifier plate, and increase the vibration transmission by changing its own size and shape.

[0039] The X-axis vibration sensor 32, the Y-axis vibration sensor 42, and the Z-axis vibration sensor 52 respectively detect vibration conditions on the X-axis, Y-axis, and Z-axis. The X-axis vibration sensor 32, the Y-axis vibration sensor 42, and the Z-axis vibration sensor 52 are conventional vibration sensors on the market, so their usage and principles are not described here in detail.

[0040] When in use, the vise-based vibration detection device is installed on the vise, the vibration transmission rod 21 is in contact with the workpiece, and the X-axis vibration sensor 32, the Y-axis vibration sensor 42, and the Z-axis vibration sensor 52 are electrically connected to an external signal receiving device. During processing, the X-axis vibration sensor 32, the Y-axis vibration sensor 42, and the Z-axis vibration sensor 52 respectively detect the vibration conditions on the X-axis, Y-axis, and Z-axis. The operator can determine whether there is any abnormality in the processing vibration based on the signal collection conditions on the external signal receiving device.

[0041] like Figure 4 As shown, in another feasible embodiment, a vise-based vibration detection device is provided, which does not include the vibration connecting member 2. When in use, it is directly fixed to the vise mouth of the vise. When the vise vibrates, it is transmitted to the inside of the vibration detection device. The X-axis vibration detection member 3, the Y-axis vibration detection member 4, and the Z-axis vibration detection member 5 detect vibrations in various directions.
