It is understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for the convenience of description, only the parts related to the present invention are shown in the accompanying drawings, rather than all of them.

[0026] In the description of this embodiment, the terms "upper", "lower", "right", "left" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0027] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0028] At present, a broken knife detection device is usually used to detect whether the blade of a tool is broken or damaged. Specifically, the driving member in the broken knife detection device moves the detection component to the detection position, and the detection component uses infrared, laser and other detection methods to determine whether the blade of the tool is intact. In the existing broken knife detection device, the moving direction of the detection component is relatively single, which is difficult to meet the detection requirements of tools with different detection positions.

[0029] To solve the above problems, Figure 1 As shown, this embodiment proposes a broken knife detection device, which includes a base 1, a first drive component 2, a slide 3, a second drive component 4 and a conductive detection member 5. The second drive component 4 is arranged on the base 1 and is transmission-connected with the slide 3 to drive the slide 3 to move along the X direction on the base 1. The first drive component 2 is arranged on the slide 3, and the output end of the first drive component 2 is insulated and connected to the conductive detection member 5 to drive the conductive detection member 5 to move along the Y direction. The X direction intersects with the Y direction; the conductive detection member 5 is electrically connected to the detection circuit.

[0030] In the broken knife detection device, the first drive component 2 drives the conductive detection member 5 to move along the Y direction, and the second drive component 4 drives the first drive component 2 to move along the X direction through the slide 3, that is, the conductive detection member 5 can move in the X direction and the Y direction, realizing the position adjustment of the conductive detection member 5 in two directions, so that the conductive detection member 5 can move to different detection positions and detect the tools with different detection positions, thereby improving the versatility of the broken knife detection device. At the same time, when the conductive detection member 5 moves to the detection position of the tool, if the conductive detection member 5 contacts and electrically conducts with the blade of the tool, it is determined that the blade of the tool is intact; if the conductive detection member 5 cannot contact and electrically conduct with the blade of the tool, it is determined that the blade of the tool is broken. By judging whether the conductive detection member 5 contacts and electrically conducts with the blade of the tool, whether the blade is broken or not can reduce the situation of misjudgment caused by impurities such as cutting fluid or chips adhering to the surface of the tool, so that the broken knife detection device can adapt to complex detection environments and improve the accuracy of detection. It should be noted that in this embodiment, the X direction is perpendicular to the Y direction. In other embodiments, the X direction and the Y direction may not be perpendicular to each other, which is not specifically limited here.

[0031] When the broken knife detection device is used to detect the blade of a tool (or drill bit) installed on a machine tool or other equipment, the base 1 is fixedly installed on the equipment where the tool to be detected is located to achieve a stable installation of the broken knife detection device. It can be understood that the conductive detection member 5 is electrically connected to the detection circuit. When the blade is intact, the conductive detection member 5 moves to the detection position of the tool, the conductive detection member 5 can contact the blade of the tool, and the detection circuit is grounded through the body of the machine where the tool is located, and the detection circuit is turned on to form a loop. When the blade is broken, the conductive detection member 5 moves to the detection position of the tool, the conductive detection member 5 does not contact the blade of the tool, and the detection circuit is disconnected and cannot form a loop. The above-mentioned control module can be a PLC control terminal, etc. Since the control module is a prior art, it will not be repeated here.

[0032] like Figure 1 and Figure 2 As shown, the second driving component 4 includes a second driving member 41, a second slide rail 42 and a second slider 43. The output end of the second driving member 41 is connected to the slide seat 3. The second slide rail 42 extends along the X direction and is arranged on the base 1. The second slider 43 is slidably arranged on the second slide rail 42. The slide seat 3 is connected to the second slider 43. The second driving member 41 drives the first driving component 2 and the conductive detection member 5 to move along the X direction through the slide seat 3 to adjust the position of the conductive detection member 5 along the X direction. The sliding cooperation between the second slide rail 42 and the second slider 43 plays a guiding and limiting role in the movement of the slide seat 3 along the X direction, thereby improving the displacement accuracy of the conductive detection member 5 along the X direction.

[0033] Specifically, Figure 2As shown, the second drive assembly 4 also includes a mounting plate 44, and the second drive member 41 is mounted on the mounting plate 44. In one embodiment, the second drive member 41 is a cylinder, and the output end of the cylinder is a screw structure, which is threadedly connected to the slide 3, thereby improving the connection strength and stability between the second drive member 41 and the slide 3. In addition, the cylinder has the advantages of simple structure, easy installation and maintenance, and high control accuracy. In other embodiments, the second drive member 41 can also be a linear motor, a hydraulic cylinder or other drive member.

[0034] In one of the embodiments, two second slide rails 42 are spaced apart on the base 1 along the Y direction, and the second sliders 43 on the two second slide rails 42 are connected to the slide 3 to avoid position displacement when the slide 3 moves along the X direction, thereby further improving the stability of the slide 3 moving along the X direction.

[0035] like Figure 3 As shown, the first driving assembly 2 includes a first driving member 21, a support plate 22 and a connecting arm 23, the first driving member 21 is arranged on the slide 3 and the output end of the first driving member 21 is connected to the support plate 22, the connecting arm 23 extends along the X direction and the first end of the connecting arm 23 is connected to the support plate 22, and the second end of the connecting arm 23 is insulated and connected to the conductive detection member 5. The first driving member 21 drives the conductive detection member 5 to move along the Y direction through the support plate 22 and the connecting arm 23 to adjust the position of the conductive detection member 5 along the Y direction. By setting the connecting arm 23, the distance between the conductive detection member 5 and the slide 3 along the X direction is increased, so that the slide 3 moves a small displacement along the X direction to enable the conductive detection member 5 to quickly reach the detection position of the tool, reducing the length of the second slide rail 42, and making the overall structure of the broken knife detection device more compact.

[0036] In one embodiment, the broken knife detection device also includes a first slide rail 26 and a first slider 27 that are slidably matched. The first slide rail 26 extends along the Y direction. One of the first slide rail 26 and the first slider 27 is installed on the slide 3, and the other of the first slide rail 26 and the first slider 27 is installed on the support plate 22. Specifically, the slide 3 is provided with the first slide rail 26 along the Y direction, the first slider 27 is slidably set on the first slide rail 26, and the support plate 22 is connected to the first slider 27. The sliding cooperation between the first slide rail 26 and the second slider 43 plays a guiding and limiting role in the movement of the slide 3 along the X direction, thereby improving the displacement accuracy of the conductive detection member 5 along the Y direction. In other embodiments, the slide 3 is provided with the first slider 27 along the Y direction, and the first slide rail 26 is installed on the support plate 22.

[0037] Specifically, the first drive assembly 2 further includes a fixed plate 28, a first slide rail 26 is arranged on one side of the slide seat 3 along the X direction, one end of the fixed plate 28 is connected to the slide seat 3, the other end of the fixed plate 28 extends out of the slide seat 3 and extends to the top of the first slide rail 26, and the first drive member 21 is arranged at the other end of the fixed plate 28. By setting the fixed plate 28 as a cantilever structure and installing the first drive member 21 on the end of the fixed plate 28 extending out of the slide seat 3, the output end of the first drive member 21 can be connected to the support plate 22 by transmission. The first slide rail 26 is installed on the slide seat 3, which makes full use of the installation space of the slide seat 3, realizes compact installation, and reduces the volume and floor space of the broken knife detection device.

[0038] In one embodiment, the first driving member 21 is a cylinder, the output end of the cylinder is a screw structure, a thickening block 29 facing the screw structure of the first driving member 21 is fixedly mounted on the support plate 22, and the screw structure of the first driving member 21 is threadedly connected to the thickening block 29, thereby improving the connection strength and stability between the first driving member 21 and the support plate 22. In addition, the cylinder has the advantages of simple structure, easy installation and maintenance, and high control accuracy. In other embodiments, the first driving member 21 can also be a linear motor, a hydraulic cylinder or other driving member.

The second hole 231 on the connecting arm 23 is a waist-shaped hole extending in the X direction, so that the connecting arm 23 can be installed on the support plate 22 with an adjustable position in the X direction. The conductive detection member 5 is driven by the first driving component 2 to adjust the position of the conductive detection member 5 in the X direction. At the same time, the connecting arm 23 performs a secondary adjustment on the position of the conductive detection member 5 in the X direction through the second hole 231, which further improves the accuracy of the position adjustment of the conductive detection member 5 in the X direction. The first fastener of this embodiment is a bolt, and the bolt is threadedly connected with the first hole 221 after the second hole 231 slides into place.

[0040] Specifically, a groove 222 is provided through the end portion of the support plate 22 connected to the connecting arm 23 along the X direction, the first hole 221 is located in the groove 222, the first end of the connecting arm 23 is slidably installed in the groove 222, and the first hole 221 is connected to the second hole 231. The groove 222 plays a limiting and guiding role in the displacement adjustment of the connecting arm 23 along the X direction, thereby improving the position adjustment accuracy of the connecting arm 23. In one embodiment, two first holes 221 are provided at intervals in the groove 222 along the Y direction, and two second holes 231 are provided at corresponding intervals at the first end of the connecting arm 23 along the Y direction, thereby improving the connection strength and stability between the support plate 22 and the connecting arm 23. In other embodiments, the number of the first holes 221 and the second holes 231 can also be flexibly adjusted.

[0041] like Figure 3 and Figure 4 As shown, the first driving assembly 2 further includes an adjustment plate 24 extending in the Y direction, the first end of the adjustment plate 24 is detachably connected to the second end of the connecting arm 23, and the second end of the adjustment plate 24 is insulated and connected to the conductive detection member 5. By providing the adjustment plate 24, the spacing between the conductive detection member 5 and the support plate 22 in the Y direction is increased, so that the conductive detection member 5 can quickly reach the detection position of the tool by moving the support plate 22 in the Y direction with a small displacement, reducing the length and volume of the first slide rail 26, and improving the compactness of the broken tool detection device.

[0042] In one embodiment, the connection position between the adjustment plate 24 and the connecting arm 23 is adjustable in the Y direction. Specifically, the second end of the connecting arm 23 is provided with a third hole 232, and the first end of the adjustment plate 24 is provided with a fourth hole 241 extending in the Y direction. The second fastener can slide in the fourth hole 241 and is sequentially inserted into the fourth hole 241 and the third hole 232 to lock and connect the second end of the connecting arm 23 with the first end of the adjustment plate 24.
