[0036] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than limiting the utility model. In addition, it should be noted that for the convenience of description, only the parts related to the utility model are shown in the drawings.

[0037] It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the drawings and embodiments.

[0038] Please refer to Figures 1 to 5 , the embodiment of the present utility model provides a new type of hole position degree inspection fixture, including a bottom plate 1, a positioning component 2, a fixing component 3 and a hole position detection pin component 4; a reference hole 71 and a center hole 72 are provided on the back plate 7. The positioning component 2 is arranged on the top surface of the bottom plate 1 corresponding to the reference hole 71 and the center hole 72 on the standard part for realizing the reference positioning of the part to be measured; the fixing component 3 is arranged on the top surface of the bottom plate 1 for pressing the top surface of the part to be measured to firmly fix the part to be measured on the bottom plate; the hole position detection pin component 4 includes three large hole detection pins 41 and one small hole detection pin 42. The large hole detection pin 4 corresponds to the large hole on the back plate (standard part), and the small hole detection pin 42 corresponds to the small hole on the back plate (standard part). The large hole detection pin 41 is used to detect the position degree of the corresponding large hole 73 of the part to be measured, and the small hole detection pin 42 is used to detect the position degree of the small hole 74 of the part to be measured;

[0039] Among them, both the large-hole detection pin member 41 and the small-hole detection pin member 42 include a positioning sleeve 411, a detection pin 412, and an elastic member 413. The positioning sleeve 411 is disposed on the bottom surface of the bottom plate 1. The detection pin 412 is slidably inserted into the corresponding positioning sleeve 411. The detection pin 412 includes a detection section and a holding portion. The detection pin 412 is perpendicularly disposed with respect to the bottom surface of the bottom plate 1. The positions, shapes, and sizes of the detection pins 412 of the large-hole detection pin member 41 and the small-hole detection pin member 42 are set corresponding to the holes to be detected on the standard part. Through holes for the corresponding detection pins 412 to penetrate are formed on the bottom plate 1. The elastic member 413 is disposed in parallel with the detection pin 412, and one end of the elastic member 413 is fixedly connected to the corresponding positioning sleeve 411, and the other end is fixedly connected to the holding portion of the corresponding detection pin 412;

[0040] When the elastic member 413 is not subjected to an external force, the elasticity of the elastic member 413 can make the detection end of the corresponding detection pin 412 located within the corresponding positioning sleeve 411;

[0041] When the elastic member 413 is pressed, the elastic member 413 is compressed, and the detection end of the corresponding detection pin 412 can penetrate through the corresponding positioning sleeve 411 and be inserted into the corresponding hole of the standard part.

[0042] Before detecting the workpiece to be measured, first perform reference positioning on the workpiece to be measured through the positioning assembly 2, and then firmly fix the workpiece to be measured on the top surface of the bottom plate 1 through the fixing assembly 3. Then, press the detection pins 412 one by one in sequence. The corresponding elastic members 413 are compressed, and the detection ends of the detection pins 412 penetrate through the corresponding positioning sleeves 411 and the corresponding through holes on the bottom plate 1 and are inserted into the corresponding hole positions of the workpiece to be measured. It is not necessary to pull out the detection pins 412 before detection, making the detection process more convenient. If multiple detection pins 412 can be inserted into the corresponding hole positions, the product is qualified; otherwise, it is unqualified. In this application, it is not necessary to repeatedly extract and insert the detection pins 412, making the detection process more convenient; after detection, release the detection pins 412, and the detection pins 412 are reset under the action of the corresponding elastic members 413. The detection sections of the detection pins 412 slide along the inner wall of the positioning sleeves 411 until the detection ends are located within the positioning sleeves 411, preventing the detection ends of the detection pins 412 from leaking out on the top surface of the bottom plate 1 and preventing the positioning and installation of the next workpiece to be measured from being affected. In this application, the elastic members 413 are used to fix the detection pins 412 to prevent the detection pins 412 from being lost.

[0043] In a preferred embodiment, as Figure 2 and Figure 4As shown, a fixing plate 414 is provided on the hand-held portion of the detection pin 412. The elastic member 413 includes a telescopic rod 4131 and a spring 4132. The telescopic rod 4131 is located between the positioning sleeve 411 and the fixing plate 414 and is arranged in two groups side by side with the detection pin 412. A spring 4132 is sleeved outside the telescopic rod 4131. One end of the spring 4132 is fixedly connected to the outer wall of the positioning sleeve 411, and the other end is fixedly connected to the top of the fixing plate 414. The telescopic rod 4131 is composed of two connecting sleeve rods that are slidably sleeved. The telescopic rod 4131 guides the spring 413, and two groups of telescopic rods 4131 are provided to improve the stability of the detection pin 412 during the sliding process.

[0044] In a preferred embodiment, as Figure 2 and Figure 4 shown, the positioning assembly 2 includes a reference pin 21 and a positioning post 22 arranged on the top surface of the bottom plate 1 corresponding to the corresponding hole positions on the standard part. A reference hole 71 and a center hole 72 are provided on the back plate 7. During detection, the reference hole 71 on the back plate 7 is inserted onto the reference pin 21, and the center hole 72 on the back plate 7 is inserted onto the positioning post 22. The back plate 7 to be detected is subjected to reference positioning through the reference pin 21 and the positioning post 22. The large-hole detection pin member 41 and the small-hole detection pin member 42 are both arranged based on the positions of the reference pin 21 and the positioning post 22.

[0045] In a preferred embodiment, as Figure 2 and Figure 3 shown, three groups of fixing components 3 are provided and are arranged in a triangular shape on the top surface of the bottom plate 1. Each group of fixing components 3 includes a clamp seat 31 and a clamp 32. The clamp 32 is arranged on the top surface of the wire pressing seat 31. One end of the clamp 32 is provided with a pressing plate 33 for pressing and fixing the top surface of the workpiece to be measured.

[0046] In a preferred embodiment, as Figure 1 shown, a base 5 is provided below the bottom plate 1. A chute 51 is opened on the top surface of the base 5 along its length direction below the bottom plate 1. A screw rod 52 is arranged in the chute 51. A slider 53 is threadedly sleeved outside the screw rod 52. The bottom of the slider 53 is slidably connected to the chute 51. The top of the slider 53 is hinged with a connecting rod 54. One end of the connecting rod 54 away from the slider 53 is hinged to the bottom of the bottom plate 1. A support 55 is also provided on the base 5. One end of the bottom plate 1 close to the support 55 is fixedly connected with a rotating rod 11, and the rotating rod 11 is rotatably connected to the support 55. During detection, by rotating the screw rod 52, the slider 53 can be driven to slide along the length direction of the chute 51, and then the bottom plate 1 can be driven to rotate around the rotating rod 11 through the connecting rod 54, so as to adjust the included angle between the bottom plate 1 and the base 5. By changing the inclination angle of the bottom plate 1, it is convenient to operate the action of the detection pin 412, and it is also more in line with ergonomics and convenient for the detection personnel to operate the inspection tool.

[0047] In a preferred embodiment, as Figure 1 shown, a rotating handle 56 is provided at one end of the screw rod 52 penetrating through the side wall of the base 5.

[0048] In a preferred embodiment, as Figure 1 shown, support feet 6 are arranged in a rectangular distribution on the bottom surface of the base 5.

[0049] Working principle: Before detecting the workpiece to be measured, insert the reference hole 71 on the backplane 7 to be detected onto the reference pin 21, and insert the central hole 72 on the backplane 7 onto the positioning post 22. Perform reference positioning on the backplane 7 to be detected through the reference pin 21 and the positioning post 22. Subsequently, drive the pressing plate 33 to press on the top surface of the backplane 7 through three groups of pressing pliers 32, firmly fix the backplane 7 to be detected on the top surface of the bottom plate 1. Then, press the detection pins 412 one by one in sequence. The corresponding elastic members 413 are compressed. The detection ends of the detection pins 412 penetrate through the corresponding positioning sleeves 411 and the corresponding through holes on the bottom plate 1 and insert into the corresponding hole positions on the backplane 7 to detect the hole position accuracy of the large holes 73 and small holes 74 on the backplane 7. It is not necessary to pull out the detection pins 412 before detection, making the detection process more convenient. If the detection pins 412 of the large hole detection pin member 41 and the small hole detection pin member 42 can both be inserted into the corresponding hole positions, the product is qualified; otherwise, it is unqualified. This application does not require multiple insertion and extraction of the detection pins 412, making the detection process more convenient. After detection, release the detection pins 412. The detection pins 412 are reset under the action of the corresponding elastic members 413. The detection sections of the detection pins 412 slide along the inner walls of the positioning sleeves 411 until the detection ends are located inside the positioning sleeves 411, preventing the detection ends of the detection pins 412 from leaking out on the top surface of the bottom plate 1 and preventing the positioning and installation of the next workpiece to be detected from being affected. This application fixes the detection pins 412 through the elastic members 413 to prevent the detection pins 412 from being lost. And during the detection process, the inclination angle of the bottom plate 1 can be adjusted according to the detection requirements, which is more in line with ergonomics and convenient for the inspectors to operate the inspection tool.
