[0036] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] Reference Figures 1 to 6 As shown, an embodiment of the present application provides a hole position detection device 100, including a base 10, a first positioning assembly 20, a pressure cover assembly 30, a first detection member 40 and a second detection member 50, wherein the first positioning assembly 20, the pressure cover assembly 30, the first detection member 40 and the second detection member 50 are all arranged on the base 10, wherein:

[0038] The first positioning component 20 is used to pass through and support the workpiece 200. The workpiece 200 that can be detected in this application is a plate product with a circular hole. The workpiece 200 has a first end and a second end. The circular hole is located at the first end of the workpiece 200. When fixing the workpiece 200, the first positioning component 20 is passed through the circular hole at the first end of the workpiece 200 to position the first end of the workpiece 200.

[0039] The pressure cover assembly 30 is used to cooperate with the base 10 and the first positioning assembly 20 to detachably fix the workpiece 200. That is, after the first positioning assembly 200 positions the workpiece 200, the pressure cover assembly 30 can adapt to the size of the circular hole at the first end of the workpiece 200 and fix the workpiece 200 together with the first positioning assembly 20. After the inspection is completed, the pressure cover assembly 30 is separated from the first positioning assembly 20 to remove the workpiece 200 from the base 10.

[0040] The first detecting member 40 is spaced apart from the first positioning assembly 20 by a preset distance, and the preset distance can be set according to a standard size of the workpiece 200 .

[0041] The second detecting member 50 is provided corresponding to the first detecting member 40 . The second detecting member 50 is inserted into the first detecting member 40 and abuts against the workpiece 200 . The abutting state of the second detecting member 40 and the workpiece 200 is used to detect whether the size of the workpiece 200 is qualified.

[0042] Based on the above embodiments, the working principle of the hole position detection device 100 of the present application is: before detection, the distance between the first detection part 40 and the first positioning component 20 is adjusted according to the standard size of the workpiece 200, and then the first positioning component 20 is used to pass through the end of the workpiece 200 with a circular hole to preliminarily position the workpiece 200, and then the pressure cover component 30 is placed on the workpiece 200, and the pressure cover component 30 and the first positioning component 20 jointly fix the workpiece 200; finally, the second detection part 50 is inserted into the first detection part 40, and the state in which the second detection part 50 is against the workpiece 200 is used to judge whether the size of the workpiece 200 meets the standard.

[0043] Reference Figure 5 and Figure 6As shown, in the embodiment provided by the present application, the first detection member 40 includes a mounting hole 41, and the second detection member 50 includes a first detection portion 51, a second detection portion 52 and a third detection portion 53 connected in sequence. The first detection portion 51, the second detection portion 52 and the third detection portion 53 are coaxially arranged cylinders, and the second detection portion 52 is located between the first detection portion 51 and the third detection portion 53. The sizes of the first detection portion 51, the second detection portion 52 and the third detection portion 53 increase in sequence.

[0044] Preferably, the first detection part 51, the second detection part 52 and the third detection part 53 are coaxially arranged rectangular blocks, the length and width of the first detection part 51 are smaller than those of the second detection part 52, and the length and width of the second detection part 52 are smaller than those of the third detection part 53.

[0045] During inspection, the second inspection member 50 is inserted into the mounting hole 41, the first inspection part 51 is closer to the mounting hole 41, and the third inspection part 53 is farthest from the mounting hole 41. If the second end of the workpiece 200 is against the side of the first inspection part 51, it indicates that the size of the workpiece 200 is too large. When the second end of the workpiece 200 is against the side of the second inspection part 52, it indicates that the size of the workpiece 200 meets the standard. If the second end of the workpiece 200 is against the side of the third inspection part 53, it indicates that the size of the workpiece 200 is too small.

[0046] In order to enable the first positioning assembly 20 to position workpieces 200 of different sizes, so as to improve the applicability of the hole position detection device 100, in the embodiment provided in this application, reference is made to Figure 3 As shown, the first positioning component 20 includes a main body portion 21 and an abutting portion 22 connected to each other, the abutting portion 22 has a first end and a second end, the first end of the abutting portion 22 is connected to the main body portion 21, and the outer diameter of the abutting portion 22 gradually shrinks from the first end of the abutting portion 22 to the second end of the abutting portion 22, that is, the abutting portion 22 is in the shape of a frustum. When the abutting portion 22 penetrates into the circular hole of the first end of the workpiece 200, when the outer wall surface of the abutting portion 22 abuts against the edge of the circular hole, it indicates that the first end of the workpiece 200 has completed positioning.

[0047] Furthermore, a first elastic member 11 is provided on the base 10. The first elastic member 11 is connected to the first positioning assembly 20. When the pressure cover assembly 30 acts on the workpiece 200, it applies a force to the workpiece 200 to fix the workpiece 200. When the workpiece 200 is acted upon by the pressure cover assembly 30, the first positioning assembly 20 simultaneously moves downward. The first elastic member 11 is elastically deformed under pressure, accumulating elastic force. This elastic force supports the first positioning assembly 20, allowing the workpiece 200 to be fixed on the first positioning assembly 20. When the inspection is completed and the workpiece 200 is removed, the elastic force accumulated by the first elastic member 11 causes the first positioning assembly 20 to move upward and reset, thereby enabling the first positioning assembly 20 to elastically reciprocate along its own axis.

[0048] In the embodiments provided in this application, refer to Figures 1 to 4 As shown, the pressure cover assembly 30 includes a pressure plate 31, a pivot seat 32 and a pressure block 33. The pressure plate 31 has a through hole 311. The position of the through hole 311 corresponds to the position of the abutment portion 22. After the workpiece 200 is fixed, the pressure plate 31 is in contact with the surface of the workpiece 200 away from the base 10. The pivot seat 32 is provided on the pressure plate 31. The pivot seat 32 includes a pivot shaft 321. The pressure block 33 includes a first end and a second end. The first end of the pressure block 33 is connected to the pivot seat 32 so that the pressure block 33 can be moved by the pivot shaft 321. The axis is the center line for rotation. In order to adapt to the clamping and fixing of workpieces 200 of different sizes, the axis of the pivot shaft 321 is set to deviate from the center of the first end of the pressure block 33, and the pressure plate 31 is located on the rotational movement path of the pressure block 33, that is, the first end of the pressure block 33 is an eccentric wheel structure. When fixing the workpiece 200, the first end of the pressure block 33 is pressed against the pressure plate 31. By rotating the pressure block 33, the pressure plate 31 and the workpiece 200 are moved downward at the same time until the edge of the circular hole at the first end of the workpiece 200 abuts against the abutment portion 22.

[0049] In a feasible embodiment, a plurality of guide rods 12 are provided on the base 10, and the pressure plate 31 is guided and matched on the guide rods 12. Under the joint guiding action of the plurality of guide rods 12, the pressure plate 31 can approach or move away from the top surface of the base 10 within a preset range, thereby enabling the workpiece 200 and the first positioning assembly 20 to move up and down stably, avoiding the position of the workpiece 200 from being offset during the movement of the pressure cover assembly 30, thereby affecting the detection results.

[0050] In order to make the pressure block 33 apply a uniform force to the pressure plate 31 so that the pressure plate 31 can move stably, refer to Figure 1 、 Figure 2 and Figure 4As shown, there are at least two pressure blocks 33, and the number of pressure blocks 33 is preferably an even number. Multiple pressure blocks 33 are evenly distributed on the side of the pressure plate 31. The hole position detection device 100 of the present application includes two pressure blocks 33, and the two pressure blocks 33 are symmetrically arranged on opposite sides of the pressure plate 31. When fixing the workpiece 200, the pressure blocks 33 on both sides of the pressure plate 31 are rotated at the same time so that the pressure plate 31 is tightly attached to the surface of the workpiece 200 and moves downward at the same time as the workpiece 200.

[0051] After the first end of the workpiece 200 is fixed, the second end of the workpiece 200 also needs to be fixed to ensure the accuracy of the detection. In the embodiment provided in this application, refer to Figures 1 to 3 As shown, the base 10 is further provided with a plurality of clamping members 13, which enclose a clamping space, and the workpiece 200 is clamped in the clamping space. Preferably, the clamping members 13 include four, and the four clamping members 13 are symmetrically arranged on opposite sides of the workpiece 200 in pairs. The space enclosed by the four clamping members 13 can clamp the workpiece 200.

[0052] In order to be able to clamp workpieces 200 of different specifications, refer to Figure 2 As shown, a second elastic member 14 is provided on the base 10, and the second elastic member 14 is connected to the second clamping member 13. When the workpiece 200 is located in the clamping space, multiple clamping members 13 respectively abut against the edges of the workpiece 200, and the workpiece 200 will give each clamping member 13 a force. This force causes the second elastic member 14 to undergo elastic deformation and accumulate elastic force. The elastic force acts on the clamping member 13, so that the clamping member 13 can maintain a state of abutting against the workpiece 200. After the workpiece 200 is removed after the inspection is completed, the elastic force accumulated by the second elastic member 14 drives the clamping member 13 to reset, so that the clamping member 13 can elastically move back and forth, and thus can adapt to the size of the workpiece 200 and expand or shrink the boundary of the clamping space.

[0053] Reference Figure 2 、 Figure 3 and Figure 5 As shown, the base 10 is further provided with a driving screw 15, which can rotate with its own axis as the center line, and the first detection member 40 is threadedly connected to the driving screw 15. In the embodiment provided in the present application, the first detection member 40 also includes a threaded hole 42, and the first detection member 40 is connected to the driving screw 15 through the threaded hole 42. When the driving screw 15 is rotated, the first detection member 40 can reciprocate along the axial direction of the driving screw 15 under the threaded cooperation between the threaded hole 42 and the driving screw 15, thereby realizing the adjustment of the preset distance between the first detection member 40 and the first positioning assembly 20.

[0054] Based on the above embodiments, the detection process of the hole position detection device of the present application is: according to the standard size of the workpiece 200 to be detected, a preset distance is set between the first positioning component 20 and the first detection component 40, the driving screw 15 is started, and the driving screw 15 is driven to rotate and drive the first detection component 40 to move along the axial direction of the driving screw 15 until the first detection component 40 moves to the position of the preset distance and then stops rotating the driving screw 15; then the circular hole of the first end of the workpiece 200 is placed on the abutment 22 of the first positioning component 20, and then the pressure plate 31 is placed on the surface of the workpiece 200 away from the main body, and the pressure blocks 33 on both sides of the pressure plate 31 are rotated so that the pressure plate 31 and the workpiece 200 move downward synchronously. When the edge of the circular hole of the workpiece 200 abuts against the outer side surface of the abutment 22 and cannot continue to move downward, the first end of the workpiece 200 is positioned.

[0055] At the same time, the second end of the workpiece 200 is clamped in the clamping space by multiple clamping members 13 on the base 10 and is positioned. After the position of the workpiece 200 is fixed, the second detection member 50 is inserted into the mounting hole 42 of the first detection member 40. If the second detection member 50 can be inserted into the first detection member 40, and the end of the workpiece 200 is against the first detection part 51, it means that the size of the workpiece 200 is too large and the size of the workpiece 200 is unqualified; if the second detection member 50 cannot penetrate into the mounting hole 42, the end of the workpiece 200 is against the third detection part 53, it means that the size of the workpiece 200 is too small and the size of the workpiece 200 is unqualified; if the second detection member 50 can penetrate into the mounting hole 42, and the end of the workpiece 200 is against the second detection part 52, it means that the size of the workpiece 200 meets the standard.

[0056] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the scope of implementation of the present invention is not limited to what is shown in the drawings. Any changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which do not exceed the spirit covered by the description and drawings, should be within the scope of protection of the present invention.
