Description

Technical Field

[0001] This utility model relates to the field of machine tool monitoring technology, and in particular to a sensor mounting base, a sensing and detection device, and machine tool equipment. Background Technology

[0002] In machine tool monitoring, the rotation of the spindle motor driving the spindle to rotate is the main spindle vibration. Spindle vibration is a common monitoring parameter, and vibration sensors are generally installed on the spindle or bearings to monitor the wear of the spindle or bearings. The spindle vibrations described in this article refer to the overall vibration of the spindle.

[0003] Vibration sensors are mounted on the spindle or bearings, and traditionally, the following mounting methods are used: Magnetic fixing: This fixing method is relatively convenient, but it is limited by the material of the fixed workpiece position. It must be an iron mounting surface. In addition, the magnetic fixing method is not a rigid connection, which will cause some interference or reduction to the data of the vibration sensor, especially for certain frequency bands.

[0004] Adhesive fixing: This fixing method is simple, quick, and low-cost, but it requires a high degree of flatness on the mounting surface, and the adhesive will lose its stickiness over time. In traditional machining environments, large temperature variations, oil mist, cutting fluid, and other factors can accelerate the occurrence of these phenomena.

[0005] Direct screw fixing: This fixing method is the best for installation, but the screw holes on site are provided by the machine tool. It cannot be guaranteed that the existing screw holes can perfectly match the installation angle of the vibration sensor, which will ultimately cause the signal collected by the vibration sensor to be decomposed.

[0006] Therefore, it is necessary to provide a new method for installing vibration sensors to solve the problems mentioned above. Utility Model Content

[0007] The present invention aims to provide a sensor mounting base, a sensing and detection device, and a machine tool, which can solve the problems of energy dispersion caused by direct bolt fixing and signal quality reduction caused by magnetic fixing in traditional vibration sensor installation methods.

[0008] To solve the above-mentioned technical problems, this utility model provides a sensor mounting base, which is fixedly mounted on a machine tool spindle and includes: a bottom and a top; The bottom part is in contact with the mounting surface provided on the machine tool spindle; The top is used to fix the vibration sensor. Each of the two sides of the top is provided with a first bolt hole and a second bolt hole that penetrate the bottom. The first bolt hole and the second bolt hole correspond to the screw holes provided on the mounting surface of the machine tool spindle. The sensor mounting base is fixedly installed on the machine tool spindle by bolts through the first bolt hole and the second bolt hole.

[0009] Optionally, if the mounting surface of the machine tool spindle is a flat mounting surface, then the bottom of the sensor mounting base is also a flat surface, and the flat surface of the bottom is in close contact with the flat mounting surface of the machine tool spindle.

[0010] Optionally, if the mounting surface of the machine tool spindle is the cylindrical surface of the machine tool spindle itself, then the bottom of the sensor mounting base is an arc surface with a preset radius, the preset radius being equal to or similar to the bottom radius of the cylindrical surface of the machine tool spindle, and the bottom arc surface of the sensor mounting base is in close contact with the cylindrical surface of the machine tool spindle.

[0011] Optionally, the top of the sensor mounting base protrudes inward from one side to form a triangular protrusion.

[0012] Optionally, the second bolt hole is located on the outer hypotenuse of the triangular protrusion.

[0013] Optionally, a screw mounting hole is provided on the inner inclined side of the triangular protrusion, and the vibration sensor is mounted on the inner inclined side using a bolt through the screw mounting hole.

[0014] Optionally, the bottom of the sensor mounting base is given a wavy texture to increase the friction between the bottom and the machine tool spindle mounting surface.

[0015] Optionally, the outer edge of the sensor mounting base is rounded.

[0016] Accordingly, a second aspect of the present invention provides a sensing and detection device, including a vibration sensor and a sensor mounting base as described in the first aspect of the present invention, wherein the vibration sensor is mounted on the sensor mounting base.

[0017] Accordingly, a third aspect of the present invention provides a machine tool device, the machine tool device including the sensing and detection device described in the second aspect of the present invention, the sensing and detection device being mounted on the machine tool spindle.

[0018] Compared to existing technologies, this utility model provides a sensor mounting base, a sensing and detection device, and a machine tool. The sensor mounting base is fixedly installed on the machine tool spindle and includes a bottom and a top. The bottom is in close contact with a mounting surface on the machine tool spindle. The top is used to fix a vibration sensor, and each of the two sides of the top has a first bolt hole and a second bolt hole penetrating the bottom. The first and second bolt holes correspond to screw holes on the mounting surface of the machine tool spindle. Bolts are used through the first and second bolt holes to fix the sensor mounting base to the screw holes on the machine tool spindle. Therefore, by using this single structural component, the sensor mounting base, with its bottom in close contact with the machine tool spindle mounting surface and secured with bolts, allows the vibration sensor installed in the mounting base to accurately detect the vibration signal data of the machine tool spindle, ensuring the accuracy and improving the quality of the vibration signal data. This solves the problems of energy dispersion caused by direct bolt fixing and signal quality degradation caused by magnetic fixing in traditional vibration sensor installation methods.

[0024] In one embodiment, such as Figure 1 , Figure 4 and Figure 5 As shown, this utility model provides a sensor mounting base 10, which is fixedly mounted on a machine tool spindle 30, and includes: a bottom 11 and a top 12; The bottom 11 is in close contact with the mounting surface provided on the machine tool spindle 30; The top 12 is used to fix the vibration sensor 20. Each of the two sides of the top 12 is provided with a first bolt hole 121 and a second bolt hole 122 that penetrates the bottom 11. The first bolt hole 121 and the second bolt hole 122 correspond to the screw holes provided on the mounting surface of the machine tool spindle 30. The sensor mounting base 10 is fixedly installed on the screw holes of the machine tool spindle 30 by bolts through the first bolt hole 121 and the second bolt hole 122.

[0025] In this embodiment, a sensor mounting base is provided, which is fixedly mounted on a machine tool spindle. The base includes a bottom and a top. The bottom is in close contact with a mounting surface on the machine tool spindle. The top is used to fix a vibration sensor. Each side of the top has a first bolt hole and a second bolt hole penetrating the bottom. The first and second bolt holes correspond to screw holes on the mounting surface of the machine tool spindle. Bolts are used to fix the sensor mounting base to the screw holes on the machine tool spindle through the first and second bolt holes. Therefore, by using this single structural component, the sensor mounting base, with its bottom in close contact with the machine tool spindle mounting surface and secured with bolts, allows the vibration sensor to accurately detect the vibration signal data of the machine tool spindle, ensuring the accuracy and improving the quality of the vibration signal data. This solves the problems of energy dispersion caused by direct bolt fixing and signal quality degradation caused by magnetic fixing in traditional vibration sensor mounting methods.

[0026] In one embodiment, the sensor mounting base 10 is made of metal.

[0027] By using a metal sensor mounting base 10, which has the same or similar material as the machine tool spindle 30, and based on the characteristic that metal can quickly transmit vibration, the vibration sensor 20 installed in the sensor mounting base 10 can accurately detect the vibration signal data of the machine tool spindle 30, ensuring the accuracy of the vibration signal data, improving the quality of the vibration signal data, and solving the problem of vibration signal decomposition and recombination.

[0028] In one embodiment, the bottom 11 of the sensor mounting base 10 is in contact with the mounting surface of the machine tool spindle 30.

[0029] Specifically, if the mounting surface of the machine tool spindle 30 is a flat mounting surface, then the bottom 11 of the sensor mounting base 10 is also a flat surface. The flat surface of the bottom 11 of the sensor mounting base 10 is in close contact with the flat mounting surface of the machine tool spindle 30, so that the bottom 11 of the sensor mounting base 10 can be perfectly attached to the flat mounting surface of the machine tool spindle 30.

[0030] If the mounting surface of the machine tool spindle 30 is the cylindrical surface of the machine tool spindle itself, then the bottom 11 of the sensor mounting base 10 is an arc surface with a preset radius. This preset radius is equal to or close to the bottom radius of the cylinder of the machine tool spindle 30. The arc surface of the bottom 11 of the sensor mounting base 10 is in close contact with the cylindrical surface of the machine tool spindle 30, so that the arc surface of the bottom 11 of the sensor mounting base 10 can perfectly fit on the cylindrical surface of the machine tool spindle 30.

[0031] In one embodiment, such as Figure 1 and Figure 4 As shown, the top 12 of the sensor mounting base 10 has a first bolt hole 121 and a second bolt hole 122 on each side, which penetrate the bottom 11. The first bolt hole 121 and the second bolt hole 122 correspond to the screw holes on the mounting surface of the machine tool spindle 30. The sensor mounting base 10 is fixedly installed on the screw holes on the mounting surface of the machine tool spindle 30 by bolts through the first bolt hole 121 and the second bolt hole 122.

[0032] Specifically, based on the size and spacing of the screw holes on the mounting surface of the machine tool spindle 30, a first bolt hole 121 and a second bolt hole 122 penetrating the bottom 11 are respectively provided at corresponding positions on both sides of the top 12 of the sensor mounting base 10, so that the first bolt hole 121 and the second bolt hole 122 correspond to the screw holes provided on the mounting surface of the machine tool spindle 30. Then, the sensor mounting base 10 is fixedly installed on the screw holes on the mounting surface of the machine tool spindle 30 using bolts through the first bolt hole 121 and the second bolt hole 122, thereby realizing the fixed installation of the sensor mounting base 10 on the machine tool spindle 30.

[0033] In one embodiment, the top 12 of the sensor mounting base 10 is used to securely mount the vibration sensor 20.

[0034] Specifically, such as Figure 1 and Figure 4 As shown, the top 12 of the sensor mounting base 10 protrudes inward from one side to form a triangular protrusion 123, which does not completely occupy the space of the top 12 of the sensor mounting base 10. For example, the triangular protrusion 123 is an equilateral triangle protrusion.

[0035] The second bolt hole 122 is located on the outer inclined side 124 of the triangular protrusion 123, and extends downward from the outer inclined side 124 through the bottom 11 of the sensor mounting base 10 to form the second bolt hole 122.

[0036] The inner inclined side 125 of the triangular protrusion 123 is provided with a screw mounting hole 126. The vibration sensor 20 is mounted on the inner inclined side 125 of the triangular protrusion 123 by using a bolt through the screw mounting hole 126, thereby fixing the vibration sensor 20 on the sensor mounting base 10.

[0037] In one embodiment, such as Figure 2 and Figure 3 As shown, the bottom 11 of the sensor mounting base 10 can be corrugated to increase the friction between the bottom 11 of the sensor mounting base 10 and the mounting surface of the machine tool spindle 30, making the installation between the sensor mounting base 10 and the machine tool spindle 30 more stable and improving the installation strength.

[0038] In one embodiment, such as Figure 1 As shown, the outer edge of the sensor mounting base 10 can be a right-angled edge. Or, as... Figure 4 As shown, the outer edge of the sensor mounting base 10 can also be rounded. Setting the outer edge of the sensor mounting base 10 to rounded corners can improve the feel, eliminate sharp edges, and prevent users from being cut by the sharp metal edges of the sensor mounting base 10.

The vibration sensor 20 is used to detect the vibration of the machine tool spindle 30 to obtain vibration signal data of the machine tool spindle 30, so that relevant equipment can determine the wear of the machine tool spindle based on the vibration signal data.

[0040] For example, vibration sensor 20 includes a triaxial acceleration sensor.

[0041] In this embodiment, a sensing and detection device is provided, including a sensor mounting base and a vibration sensor. The sensor mounting base is mounted on a machine tool spindle, and the vibration sensor is mounted on the sensor mounting base. The vibration sensor is used to detect the vibration of the machine tool spindle to obtain vibration signal data of the machine tool spindle, so that relevant equipment can determine the wear of the spindle based on the vibration signal data.
