[0045] Tool 200 Specific embodiments

[0046] The following details the embodiments of the present application. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present application and should not be construed as a limitation of the present application.

[0047] Please refer to Figure 1 , an embodiment of the present application provides a tool detection device 100 for detecting whether a tool 200 is broken or for tool setting of the tool 200. Specifically, please refer to Figure 2 and Figure 3, the tool detection device 100 includes a main body 10, a sensor 20, a moving member 30, a detecting member 40, and an adjusting member 50.

[0048] The sensor 20 is disposed inside the main body 10. The moving member 30 is elastically disposed inside the main body 10 and is disposed opposite to the sensor 20. The detecting member 40 is slidably disposed on the main body 10. The detecting member 40 is sleeved outside the moving member 30 and is connected to one end of the moving member 30 away from the sensor 20. The detecting member 40 has a detecting surface 41 for being abutted by the tool 200. The adjusting member 50 is respectively connected to the detecting member 40 and the moving member 30 to adjust the flatness of the detecting surface 41 of the detecting member 40. Wherein, when the detecting surface 41 of the detecting member 40 is pushed by the tool 200, the moving member 30 can be driven to move towards the sensor 20, so that the moving member 30 contacts the sensor 20 and the sensor 20 generates a sensing signal, thereby detecting whether the tool 200 is broken or performing tool setting on the tool 200 according to the sensing signal.

[0049] In the above-mentioned tool detection device 100, by pushing the detecting surface 41 of the detecting member 40 to move with the tool 200, the detecting member 40 will drive the moving member 30 to move towards the sensor 20, so that the moving member 30 contacts the sensor 20 and the sensor 20 generates a sensing signal, thereby detecting whether the tool 200 is broken or performing tool setting on the tool 200 according to the sensing signal; since the flatness of the detecting surface 41 of the detecting member 40 is adjusted by the adjusting member 50 before detection, there will be no problem of inclination of the detecting surface 41, and the detection accuracy of the tool 200 is relatively high.

[0050] The main body 10 is generally a cylindrical structure. An accommodation cavity 11 is formed inside the main body 10. Both the sensor 20 and the moving member 30 are disposed inside the accommodation cavity 11.

[0051] The tool detection device 100 further includes a heightening column 60, a base 70, and a fixing member 80. The heightening column 60 is disposed on the base 70, and the main body 10 is disposed on the heightening column 60. The heightening column 60 is used to increase the height of the main body 10. The fixing member 80 is a columnar structure and is located between the heightening column 60 and the main body 10. Wherein, the fixing member 80 is sleeved outside a part of the sensor 20.

[0052] The sensor 20 can be an IP67-class precision sensor, which is fixed on the fixing member 80 by two nuts. The wire outlet at the bottom of the IP67-class precision sensor is sealed by a plastic plug to prevent dust and water.

[0053] It can be understood that a blowing structure (not shown in the figure) can be provided on one side of the tool detection device 100. After the blowing structure is ventilated, it can blow air towards the detecting surface 41 to avoid residual aluminum chips and other sundries from affecting the detection accuracy.

[0054] The adjusting member 50 includes a flatness correction portion 51 and a plurality of adjusting portions 52. The flatness correction portion 51 is movably clamped on the outer periphery of the moving member 30; the plurality of adjusting portions 52 are rotatably arranged in the detecting member 40 and on the circumferential side of the moving member 30, and one end of each adjusting portion 52 abuts against one side of the flatness correction portion 51. Specifically, there are four adjusting portions 52, and the adjusting portions 52 are bolts. In this way, when the detection surface 41 is in an inclined state, at least one adjusting portion 52 can be adjusted. That is, if a certain area has a lower height, the adjusting portion 52 near the lower height direction is adjusted to straighten this area, and vice versa if it is high.

[0055] A clamping groove 31 is formed on the outer periphery of the moving member 30. The flatness correction portion 51 includes a flatness correction disc 511 and a locking nut 512. The flatness correction disc 511 is movably clamped in the clamping groove 31 on the outer periphery of the moving member 30; the locking nut 512 is rotatably arranged on the moving member 30, and the locking nut 512 abuts against one side of the flatness correction disc 511. In this way, by providing the locking nut 512, the flatness correction disc 511 can be locked in the clamping groove 31, and the flatness correction disc 511 is relatively convenient to disassemble.

[0056] One end of the moving member 30 is provided with a spherical portion 32. The spherical portion 32 is inserted into the detecting member 40 and abuts against the detecting member 40. In this way, when the detection surface 41 is in an inclined state, due to the spherical portion 32 of the moving member 30 abutting against the detecting member 40 and the flatness correction portion 51 being movably clamped on the outer periphery of the moving member 30, adjusting at least one adjusting portion 52 will cause the detecting member 40 to move relative to the moving member 30, thereby adjusting the flatness of the detection surface 41 of the detecting member 40.

[0057] The tool detection device 100 further includes an elastic member 90. The elastic member 90 is arranged in the main body 10 and sleeved on the outer periphery of the sensor 20. One end of the moving member 30 close to the sensor 20 abuts against the elastic member 90. Specifically, the elastic member 90 is a spring. By providing the elastic member 90, the moving member 30 can be reset after detection.

[0058] One end of the moving member 30 away from the spherical portion 32 is provided with a stop portion 33. The stop portion 33 abuts against the elastic member 90. The stop portion 33 is an annular flange and is located on the outer periphery of the moving member 30. The elastic member 90 is sleeved on the end of the moving member 30. In this way, the elastic member 90 can be prevented from shaking and deviating from the moving member 30, thereby affecting the reset of the moving member 30.

[0059] A limiting hole 34 is formed in the moving member 30. The limiting hole 34 is an oblong hole. The tool detection device 100 further includes a limiting member 92. The limiting member 92 is rod-shaped. The limiting member 92 is disposed on the main body 10, and the limiting member 92 passes through the limiting hole 34 to limit the moving distance of the moving member 30. The extending direction of the limiting member 92 is perpendicular to the extending direction of the moving member 30. Specifically, the limiting member 92 includes two relatively arranged screw rods 922. One end of each screw rod 922 extends into the limiting hole 34, and the other end of each screw rod 922 is rotatably connected to the inside of the main body 10 through a threaded structure. In this way, the displacement of the moving member 30 in its extending direction can be limited, and the limiting member 92 can limit the rotation of the moving member 30.

[0060] The detection member 40 includes a sliding portion 42 and a detection portion 43. Both the sliding portion 42 and the detection portion 43 are cylindrical. The diameter of the sliding portion 42 is larger than that of the detection portion 43. The sliding portion 42 is slidably sleeved on the main body 10 and is sleeved outside the moving member 30; the detection portion 43 is disposed on one side of the sliding portion 42. The spherical portion 32 is inserted into the detection portion 43 and abuts against the detection portion 43. The detection surface 41 is disposed on the side of the detection portion 43 away from the sliding portion 42. In this way, the sliding portion 42 is slidably sleeved on the main body 10, which can protect the structure inside the main body 10.

[0061] A replaceable contact piece 44 is provided on the detection surface 41. Specifically, the contact piece 44 can be a tin steel sheet with good wear resistance. In this way, when the wear of the contact piece 44 affects the detection accuracy, the spare contact piece 44 can be directly replaced to re-calibrate the level, and the replacement is relatively convenient.

[0062] The tool detection device 100 further includes a locking member 95. The locking member 95 passes through the sliding portion 42 and abuts against the moving member 30 to connect the moving member 30 and the sliding portion 42. Specifically, there are four locking members 95, and they are all disposed on the circumferential side of the moving member 30. The locking member 95 is a bolt.

[0063] The implementation process of the tool detection device 100 in this embodiment is as follows:

[0064] First, the levelness of the detection surface 41 is detected. When the detection surface 41 is in an inclined state and a certain area has a lower height, the adjusting portion 52 near the lower height direction is adjusted to make the area level, and vice versa if it is high; then the tool 200 is used to push against the detection surface 41 of the detection member 40 to move. The detection member 40 will drive the moving member 30 to move towards the sensor 20. The moving member 30 contacts the sensor 20 and causes the sensor 20 to generate a sensing signal, so as to detect the tool 200 according to the sensing signal. At this time, the elastic member 90 is compressed; then the tool 200 is moved, the detection member 40 is not stressed, and the detection member 40 and the moving member 30 are reset under the action of the elastic member 90.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and not to limit them. Although the present application has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present application can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present application.
