[0032] Reference Figure 1 , Figure 2 According to the verticality detection device of the embodiment of the utility model, it includes a mounting seat 100, a connecting component 200, a reference part 300 and a measuring component 400. The mounting seat 100 is used to be fixedly connected to the moving platform of the grain sorting machine. The connecting component 200 is rotatably arranged on the mounting seat 100. The reference part 300 is arranged on the connecting component 200. The reference part 300 has a first measuring surface 310 and a second measuring surface 320. The first measuring surface 310 and the second measuring surface 320 are vertically arranged. The measuring component 400 is arranged between the mounting seat 100 and the connecting component 200. The measuring component 400 can drive the connecting component 200 to rotate relative to the mounting seat 100 to measure the verticality of the X-axis and the Z-axis of the moving platform. The operation is simple, convenient and fast, and the verticality of the X-axis and the Z-axis of the moving platform can be accurately and efficiently detected.

[0033] Specifically, when detecting the verticality of the X-axis and the Z-axis of the motion platform, the mounting base 100 is fixed on the motion platform, and the operator can drive the connecting component 200 to rotate relative to the mounting base 100 through the measuring component 400 so that the first measuring surface 310 is parallel to the X-axis of the motion platform. At this time, the measuring component 400 obtains a first measurement value, and the first measuring surface 310 can be used as a reference surface. The connecting component 200 can be driven to rotate relative to the mounting base 100 through the measuring component 400 so that the second measuring surface 320 is parallel to the Z-axis of the motion platform. At this time, the measuring component 400 obtains a second measurement value. The difference between the second measurement value and the first measurement value is the verticality of the X-axis and the Z-axis of the motion platform. The operation is simple, convenient and fast, and can accurately and efficiently detect the verticality of the X-axis and the Z-axis of the motion platform.

[0034] Reference Figure 3 , Figure 4 In some embodiments of the utility model, the connecting assembly 200 includes a negative pressure suction cup 210 and a pivot seat 220. The pivot seat 220 is pivotally connected to the mounting seat 100. The negative pressure suction cup 210 is disposed on the pivot seat 220. The negative pressure suction cup 210 is connected to the reference part 300, which can reduce the deformation of the reference part 300 to improve the detection accuracy of the verticality detection device.

[0035] Specifically, the negative pressure suction cup 210 is used to connect to the negative pressure source. The negative pressure suction cup 210 can absorb the reference part 300 through negative pressure to limit the movement of the reference part 300 relative to the pivot seat 220, thereby reducing the deformation of the reference part 300 and improving the detection accuracy of the verticality detection device.

[0036] It should be noted that the pivot seat 220 includes three pivot blocks 221, and the three pivot blocks 221 are arranged at intervals along the circumferential direction, which can reduce the overall weight of the connecting assembly 200 to facilitate transportation and handling of the verticality detection device, which will not be described in detail here.

[0037] Of course, in some specific implementations, the three pivot blocks 221 may also be connected to each other, so that the pivot seat 220 is annular in structure, which can facilitate the pivot seat 220 to be pivotally connected to the mounting seat 100, and is not limited here.

[0038] Reference Figure 3 , Figure 4 and Figure 7 In some embodiments of the present invention, the connecting component 200 also includes an abutment member 230, one end of which is connected to the pivot seat 220, and the other end of the abutment member 230 can abut against the movable end 410 of the measuring component 400, which can facilitate the operator to drive the reference member 300 to rotate through the measuring component 400.

[0039] Reference Figure 2 , Figure 5 and Figure 6 In some embodiments of the utility model, an elastic member 500 is provided between the abutment member 230 and the mounting seat 100, and the elastic member 500 is used to make the end of the abutment member 230 away from the pivot seat 220 abut against the movable end 410 of the measuring component 400, so as to prevent the reference member 300 from being separated from the movable end 410 of the measuring component 400 due to its own inertia, which can facilitate the operator to detect the X-axis and Z-axis of the motion platform.

[0040] Specifically, a first hook is provided at one end of the elastic member 500, and a second hook is provided at the other end of the elastic member 500. The first hook is connected to the mounting seat 100 through a first fastener, and the second hook is connected to one end of the abutment 230 away from the pivot seat 220 through a second fastener. When the movable end 410 of the measuring component 400 drives the abutment 230 to move, the elastic member 500 is stretched, and the elastic potential energy of the elastic member 500 increases. The elastic member 500 can apply a force to the abutment 230 so that one end of the abutment 230 away from the pivot seat 220 abuts against the movable end 410 of the measuring component 400, so as to avoid the reference member 300 from being separated from the movable end 410 of the measuring component 400 under its own inertia, which can facilitate the operator to detect the X-axis and Z-axis of the motion platform.

[0041] It should be noted that the movable end 410 of the measuring component 400 may also be in contact with the mounting seat 100 , and the measuring component 400 is disposed on the pivot seat 220 , which can conveniently drive the reference member 300 to rotate relative to the mounting seat 100 , and is not limited here.

The plurality of first adsorption grooves 212 are arranged at intervals along the circumference of the negative pressure suction cup 210. The negative pressure channel 211 is used to communicate with a negative pressure source. The negative pressure channel 211 is connected to the first adsorption grooves 212, which can increase the contact area between the negative pressure suction cup 210 and the reference part 300, so that the reference part 300 can be stably adsorbed by the negative pressure suction cup 210.

[0044] Specifically, there are four first adsorption grooves 212. Along the thickness direction perpendicular to the negative pressure suction cup 210, the cross-section of the first adsorption groove 212 is a U-shaped structure. The four first adsorption grooves 212 are arranged at intervals along the circumference of the negative pressure suction cup 210 and are correspondingly connected, which can increase the contact area between the negative pressure suction cup 210 and the reference part 300, so that the reference part 300 can be stably adsorbed by the negative pressure suction cup 210.

[0045] It should be noted that the negative pressure suction cup 210 can be configured with one or more. When the negative pressure suction cup 210 is configured with multiple, the multiple negative pressure suction cups 210 are arranged in an array at intervals along the circumferential direction, which will not be described in detail here.

[0047] Specifically, the multiple second adsorption grooves 213 are all located on the inner side of the multiple first adsorption grooves 212, and the multiple second adsorption grooves 213 are in a concentric circle structure, which can increase the contact area between the negative pressure suction cup 210 and the reference part 300, so that the reference part 300 can be stably adsorbed by the negative pressure suction cup 210.

[0048] Reference Figure 4 , Figure 7 In some embodiments of the utility model, the pivot seat 220 is pivotally connected to the mounting seat 100 through the bearing 240. The mounting seat 100 is provided with a first mounting groove 101. The outer ring of the bearing 240 is accommodated in the first mounting groove 101. The negative pressure suction cup 210 and the pivot seat 220 are enclosed to form a second mounting groove 201. The inner ring of the bearing 240 is accommodated in the second mounting groove 201, which can facilitate the installation and fixing of the bearing 240.

[0049] Specifically, the opposite sides of the outer ring of the bearing 240 respectively abut against the opposite side walls of the first installation groove 101, and the opposite sides of the inner ring of the bearing 240 respectively abut against the opposite side walls of the second installation groove 201, which can facilitate the installation and fixing of the bearing 240.

[0050] Reference Figure 3 , Figure 4 In some embodiments of the utility model, a positioning member 600 is further included. The positioning member 600 is detachably connected to the mounting seat 100. The positioning member 600 is provided with a positioning surface 610. The positioning surface 610 is in contact with the first measuring surface 310 or the second measuring surface 320, and the reference member 300 can be positioned so that the center position of the reference member 300 coincides with the center position of the negative pressure suction cup 210, thereby improving the detection accuracy of the verticality detection device.

[0051] Specifically, when installing the reference part 300, the positioning part 600 is connected to the mounting seat 100. Then, the reference part 300 is placed on the negative pressure suction cup 210. The relative positions of the reference part 300 and the negative pressure suction cup 210 are adjusted so that the first side surface or the second side surface is in contact with the positioning surface 610 to position the reference part 300. Then, the negative pressure source is started so that the negative pressure suction cup 210 fixes the reference part 300. After that, the positioning part 600 is removed and the verticality detection device can be used normally, which can improve the detection accuracy of the verticality detection device.

[0052] It should be noted that the positioning member 600 is detachably connected to the mounting base 100 by bolting or clamping, which will not be described in detail here.

[0053] Of course, in some specific embodiments, the positioning member 600 can also be connected to the pivot seat 220, so that the positioning member 600 can rotate with the rotation of the pivot seat 220.
