[0002] Fasteners are often combined with mounting holes. They are easy to use and are widely used in various fields. There are currently two main detection methods for the depth detection of fastener mounting holes: 1. Sectioning projection method: symmetrically cut the nut fastener along the hole depth direction and use a projector or a three-coordinate measuring instrument for measurement; 2. Vernier caliper detection method: use the depth end measurement method of the vernier caliper for measurement.

[0003] Regarding the above two methods, the first method will cause irreversible damage to the installed device and has low efficiency. The second method has high requirements on the operation of the staff, and the numerical error detected is also large and the accuracy is not high. Summary of the invention

[0004] The object of the present invention is to provide a fastener hole detection device to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: The present invention provides a technical solution for a fastener hole detection device, the detection device includes a bottom plate, a top plate and a diameter detection component, an upper through hole is opened in the middle of the bottom plate, a connecting block is provided on the upper surface of the bottom plate, a diameter detection component is provided on the top of the connecting block, columns are provided at the four corners of the upper surface of the bottom plate, a top plate is provided on the top of the column, the top plate is fixedly connected to the column, a support component is provided at the bottom end of the bottom plate, and a guide block is provided in the middle of the bottom of the bottom plate.

[0006] Its detection device is used to detect the hole position of the fastener installation, so as to know the depth and width of the installation hole, and whether the inner wall of the installation hole is polished and tilted, thereby improving work efficiency. The bottom plate and the top plate are fixed parts, and the diameter detection component is located between the two and is pushed by the driving device. The column is used to fix the bottom plate and the top plate, and then the support component is used to support the overall component so that the device stands on the installation hole, which is convenient for the staff to adjust. The guide block at the bottom of the bottom plate is used to assist the upper through hole to align with the installation hole, so that the diameter detection component can directly enter the installation hole.

[0007] Furthermore, the diameter detection component includes a first driving push rod and a detection head. The fixed end of the first driving push rod is fixedly connected to the bottom end of the top plate, the output end of the first driving push rod faces the bottom plate, the first driving push rod and the upper through hole are on the same central axis, and the output end of the first driving push rod is provided with a detection head, which is fixedly connected to the output end of the first driving push rod.

[0008] The first driving push rod is used as a power source to control the downward movement of the detection head and push the detection head to move into the mounting hole. The shell in the first driving push rod is fixedly connected to the bottom end of the top plate and the top end of the connecting block. The connecting block is annular. The internal space of the connecting block is connected to the upper through hole. The detection head, the first driving push rod and the connecting block are on the same central axis. The first driving push rod will push the detection head through the upper through hole to move to the bottom end of the bottom plate.

[0009] Furthermore, the detection head includes a column and an extrusion head, one end of the column is fixedly connected to the output end of the first driving push rod, a hollow cavity is opened in the column, an extrusion head is provided at the bottom end of the column, the extrusion head is slidably connected to the column, a threaded column is provided at the top of the extrusion head, an inner bearing is sleeved on the threaded column, the inner bearing is threadedly connected to the threaded column, an outer bearing is provided on the outer wall of the inner bearing, a connecting rod is provided on the upper surface of the inner bearing, one end of the connecting rod is rotatably connected to the inner bearing, and the other end of the connecting rod is rotatably connected to the arc plate.

[0010] The column serves as the main body of the detection head, and the extrusion head is used to contact the bottom end of the inner wall of the mounting hole, and the extrusion head is slidably connected to the bottom end of the column. Therefore, after the first driving push rod pushes the detection head to move, the bottom end of the detection head will contact the bottom end of the inner wall of the mounting hole, so that the extrusion block at the bottom end of the detection head will be compressed and move upward. The movement of the extrusion block will drive the threaded column to move upward, and its bearing sleeve is arranged on the threaded column. When the threaded column moves, the inner bearing in its bearing will rotate with the movement of the threaded column. Since the outer bearing is fixedly connected to the inner wall of the column, its bearing will not be affected. When the first driving push rod retracts, the output end drives the detection head to move upward, and then the extrusion head moves downward due to its own weight, the extrusion head drives the threaded column to reverse, the threaded column drives the inner bearing to rotate, the inner bearing drives one end of the connecting rod to rotate, and the other end of the connecting rod drives the arc plate to move toward the outer wall of the column.

[0011] Furthermore, a telescopic assembly is provided on one side of the arc plate, and the telescopic assembly includes a telescopic rod, one end of the telescopic rod is rotatably connected to the arc plate, and the other end of the telescopic rod is rotatably connected to the column, a spring is sleeved on the telescopic rod, and first capacitor blocks are provided at both ends of the telescopic rod, and the first capacitor block is electrically connected to the telescopic rod.

[0012] The telescopic rod is provided with two at the upper and lower ends of the arc plate, one end of the telescopic rod is rotatably connected to the arc plate, and the other end is rotatably connected to the column. A spring is sleeved on the telescopic rod, and the spring is used to push the arc plate away from the column. The connecting rod limits the movement of the arc plate, so that when the arc plate contacts the inner wall of the mounting hole, the spring will continue to apply force to push one end of the arc plate to move toward the inner wall of the mounting hole, and then first capacitor blocks are provided at both ends of the telescopic rod, and the resistance value between the two first capacitor blocks will change with the moving distance. When the resistance value of the telescopic rod at the top end of the same arc plate is significantly different from the resistance value of the telescopic rod at the bottom end, the inclination of the inner wall of the mounting hole is judged according to the difference, and the bottom depression or top depression is also judged according to the resistance values ​​of the two telescopic rods.

[0013] Furthermore, the supporting assembly includes a connecting member and a second driving push rod, the connecting member is bolted to the bottom end of the base plate, the second driving push rod is fixedly connected to the connecting member, and a magnetic block is provided at the bottom end of the second driving push rod.

[0014] The supporting assembly is used to support the whole assembly so that the device stands on the mounting hole, which is convenient for the staff to adjust. The connecting piece is used to connect with the base plate. The connecting piece is parallel to the base plate. The second driving push rod is perpendicular to the connecting piece. The fixed end of the second driving push rod is fixedly connected to the connecting piece. The output end of the second driving push rod is embedded with a magnetic block. The magnetic block is used to contact the surface where the mounting hole is located to improve the grip and the applicable environment. The second driving push rod and the connecting piece are both provided with four located at the four corners of the bottom end of the base plate. By controlling the extension and retraction degree of the second driving push rod, the mounting hole can be detected in environments with different height differences.

[0015] Furthermore, depth detection components are provided on both sides of the column, and the depth detection components include a sliding rod and an iron plate. Sliding grooves are opened on both sides of the column, and sliding rods are provided on the sliding grooves. The sliding rods are slidably connected to the sliding grooves. An iron plate is provided on one side of the inner wall of the sliding groove, and the iron plate is fixedly connected to the inner wall of the sliding groove. A second auxiliary capacitor block is provided at one end of the sliding groove, and the second auxiliary capacitor block is electrically connected to the iron plate. A second main capacitor block is provided at one end of the sliding rod, and the second main capacitor block is located on a side of the sliding rod close to the iron plate, and the second main capacitor block is electrically connected to the iron plate.

[0016] The depth detection component is used to measure the depth inside the mounting hole. The depth detection component is provided with two components located on both sides of the column and also between the two arc-shaped plates. Under normal conditions, the sliding rod is located at the bottom of the sliding groove, and the sliding groove is parallel to the central axis of the column. Therefore, when the first driving push rod pushes the detection head to move downward, the bottom end of the sliding rod contacts the opening of the mounting hole and is restricted by the mounting hole. However, since the sliding rod is slidably connected to the sliding groove, the sliding rod will be driven by the opening to move upward in the sliding groove. During this period, the second main capacitor block on the sliding rod will move on the iron plate, and the second main capacitor block is connected to the iron plate wire, and the second auxiliary capacitor block is also connected to the iron plate wire. Therefore, when the sliding rod moves, the distance between the second main capacitor block and the second auxiliary capacitor block will be shortened, so that the resistance value between the two will change. The farther the distance between the two is, the higher the resistance value. Conversely, the closer the distance between the two is, the lower the resistance value. The depth of the mounting hole can be known based on the changed resistance value.

[0017] Furthermore, the guide block is connected with the bottom plate by bolts, a lower through hole is opened in the middle of the guide block, the lower through hole is connected with the upper through hole, and a laser indicator light is arranged outside the lower through hole.

[0018] The guide block is located at the bottom end of the base plate. The guide block and the upper through hole of the base plate are on the same central axis. The guide block is connected to the base plate by bolts. When the guide block is located at the bottom end of the base plate, its laser indicator light is turned on, and the output end of the laser indicator light is located above the mounting hole. The output end of the laser indicator light is used to determine whether the detection head is located above the mounting hole.

[0019] Furthermore, a control terminal is provided between the bottom plate and the top plate.

[0020] A control panel is provided in the control terminal, and the difference produced by the first capacitor block on the telescopic rod will be reflected on the control panel, so that the staff can judge the inclination of the inner wall of the installation hole by the numerical value, and then the value of the first capacitor block on the depth detection component will also be reflected on the control panel. The control panel is electrically connected to the first driving push rod, and the control panel is electrically connected to the second driving push rod.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. In the present invention, the detection head pushes the column through the first driving push rod, so that the pressure head contacts the bottom end of the inner wall of the mounting hole, and through the cooperation of the inner bearing and the annular plate, the inner diameter of the mounting hole is judged by the resistance value between the two first capacitor blocks on the telescopic rod.

[0023] 2. In the present invention, the telescopic assembly pushes the upper and lower ends of the arc-shaped plate, so that the inclination of the inner wall of the mounting hole can be known through the numerical difference between the upper and lower ends.

[0024] 3. In the present invention, as the first driving push rod works, the bottom end of the sliding rod of the depth detection component contacts the opening of the mounting hole and is restricted by the mounting hole. The sliding rod is driven by the opening to move upward in the sliding groove, thereby changing the distance between the second main capacitor block and the second auxiliary capacitor block. The depth of the mounting hole can be known based on the changed resistance value. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Specifically, the detection device is used to detect the hole position of the fastener installation, so as to know the depth and width of the installation hole, and whether the inner wall of the installation hole is polished and tilted, so as to improve work efficiency. The bottom plate 1 and the top plate 2 are fixed parts, and the diameter detection component 3 is located between the two. It is pushed by the driving device. The column 4 is used to fix the connection between the bottom plate 1 and the top plate 2, and then the support component 5 is used to support the whole component, so that the device stands on the installation hole, which is convenient for the staff to adjust. The guide block 6 at the bottom of the bottom plate 1 is used to assist the upper through hole 11 to align with the installation hole, so that the diameter detection component 3 can directly enter the installation hole.

[0038] like Figure 5 As shown, the diameter detection assembly 3 includes a first driving push rod 31 and a detection head 32. The fixed end of the first driving push rod 31 is fixedly connected to the bottom end of the top plate 2, the output end of the first driving push rod 31 faces the bottom plate 1, the first driving push rod 31 and the upper through hole 11 are on the same central axis, and the output end of the first driving push rod 31 is provided with a detection head 32, and the detection head 32 is fixedly connected to the output end of the first driving push rod 31.

[0039] Specifically, the first driving push rod 31 is used as a power source to control the detection head 32 to move downward, pushing the detection head 32 to move into the mounting hole. The shell in the first driving push rod 31 is fixedly connected to the bottom end of the top plate 2 and the top end of the connecting block. The connecting block is annular, and the internal space of the connecting block is connected to the upper through hole 11. The detection head 32, the first driving push rod 31 and the connecting block are on the same central axis. The first driving push rod 31 will push the detection head 32 to move through the upper through hole 11 to the bottom end of the bottom plate 1.

[0040] like Figure 5 , Figure 7 , Figure 8As shown, the detection head 32 includes a column 321 and an extrusion head 322, one end of the column 321 is fixedly connected to the output end of the first driving push rod 31, a hollow cavity 3211 is opened in the column 321, an extrusion head 322 is provided at the bottom of the column 321, the extrusion head 322 is slidably connected to the column 321, a threaded column 323 is provided at the top of the extrusion head 322, an inner bearing 324 is sleeved on the threaded column 323, the inner bearing 324 is threadedly connected to the threaded column 323, an outer bearing 325 is provided on the outer wall of the inner bearing 324, a connecting rod 326 is provided on the upper surface of the inner bearing 324, one end of the connecting rod 326 is rotatably connected to the inner bearing 324, and the other end of the connecting rod 326 is rotatably connected to the arc plate 327.

[0041] Specifically, the column 321 serves as the main body of the detection head 32, and the extrusion head 322 is used to contact the bottom end of the inner wall of the mounting hole, and the extrusion head 322 is slidably connected to the bottom end of the column 321, so that after the first driving push rod 31 pushes the detection head 32 to move, the bottom end of the detection head 32 will contact the bottom end of the inner wall of the mounting hole, so that the extrusion block at the bottom end of the detection head 32 will be pressurized and move upward, and the movement of the extrusion block will drive the threaded column 323 to move upward, and its bearing sleeve is arranged on the threaded column 323. When the threaded column 323 moves, the inner bearing 324 in its bearing will rotate with the movement of the threaded column 323, wherein because the outer bearing 325 is fixedly connected to the inner wall of the column 321, the inner bearing 324 will not be driven upward Move, and then when the inner bearing 324 rotates, it will drive one end of the connecting rod 326 to move in an arc shape, and the other end of the connecting rod 326 will push the arc plate 327 to move outward, and the arc plate 327 will contact the inner wall of the mounting hole. There are four arc plates 327, and the arc plates 327 cooperate with the outer wall of the column 321. When the first driving push rod 31 retracts, the output end will drive the detection head 32 to move upward, and then the extrusion head 322 moves downward due to its own weight, the extrusion head 322 drives the threaded column 323 to reverse, the threaded column 323 drives the inner bearing 324 to rotate, the inner bearing 324 drives one end of the connecting rod 326 to rotate, and the other end of the connecting rod 326 drives the arc plate 327 to move toward the outer wall of the column 321.

[0042] like Fig. 9 As shown, a telescopic component 33 is provided on one side of the arc plate 327, and the telescopic component 33 includes a telescopic rod 331. One end of the telescopic rod 331 is rotatably connected to the arc plate 327, and the other end of the telescopic rod 331 is rotatably connected to the column 321. A spring 332 is sleeved on the telescopic rod 331, and first capacitor blocks 333 are provided at both ends of the telescopic rod 331. The first capacitor block 333 is electrically connected to the telescopic rod 331.

[0043] Specifically, the telescopic rod 331 is provided with two ends located at the upper and lower ends of the arc plate 327. One end of the telescopic rod 331 is rotatably connected to the arc plate 327, and the other end is rotatably connected to the column 321. A spring 332 is sleeved on the telescopic rod 331. The spring 332 is used to push the arc plate 327 away from the column 321. The connecting rod 326 limits the movement of the arc plate 327. Therefore, when the arc plate 327 contacts the inner wall of the mounting hole, the spring 332 will continue to apply force to push one end of the arc plate 327 to move toward the inner wall of the mounting hole. Then, first capacitor blocks 333 are provided at both ends of the telescopic rod 331. The resistance value between the two first capacitor blocks 333 will change with the moving distance. When the resistance value of the telescopic rod 331 at the top end of the same arc plate 327 is greatly different from the resistance value of the telescopic rod 331 at the bottom end, the inclination of the inner wall of the mounting hole is judged according to the difference, and the bottom depression or the top depression is judged according to the resistance values ​​of the two telescopic rods 331.

[0044] like Figure 2 , Figure 4 As shown, the support assembly 5 includes a connecting member 51 and a second driving push rod 52. The connecting member 51 is bolted to the bottom end of the base plate 1, and the second driving push rod 52 is fixedly connected to the connecting member 51. A magnetic block 53 is provided at the bottom end of the second driving push rod 52.

[0045] Specifically, the support assembly 5 is used to support the entire assembly so that the device stands on the mounting hole to facilitate adjustment by the staff. The connecting piece 51 is used to connect with the base plate 1. The connecting piece 51 is parallel to the base plate 1. The second driving push rod 52 is perpendicular to the connecting piece 51. The fixed end of the second driving push rod 52 is fixedly connected to the connecting piece 51. The output end of the second driving push rod 52 is embedded with a magnetic block 53. The magnetic block 53 is used to contact the surface where the mounting hole is located to improve the grip and the applicable environment. The second driving push rod 52 and the connecting piece 51 are both provided with four located at the four corners of the bottom end of the base plate 1. By controlling the telescopic degree of the second driving push rod 52, the mounting hole can be detected in environments with different height differences.

[0046] like Figure 5 , Figure 6 As shown, depth detection components 7 are provided on both sides of the column 321, and the depth detection components 7 include a sliding rod 71 and an iron plate 72. Sliding grooves 3212 are opened on both sides of the column 321, and the sliding grooves 3212 are provided with sliding rods 71. The sliding rods 71 ​​are slidably connected to the sliding grooves 3212. An iron plate 72 is provided on one side of the inner wall of the sliding groove 3212, and the iron plate 72 is fixedly connected to the inner wall of the sliding groove 3212. A second auxiliary capacitor block 73 is provided at one end of the sliding groove 3212, and the second auxiliary capacitor block 73 is electrically connected to the iron plate 72. A second main capacitor block 74 is provided at one end of the sliding rod 71, and the second main capacitor block 74 is located on the side of the sliding rod 71 close to the iron plate 72, and the second main capacitor block 74 is electrically connected to the iron plate 72.

[0047] Specifically, the depth detection component 7 is used to measure the depth of the mounting hole. The depth detection component 7 is provided with two parts located on both sides of the column 321 and between the two arc-shaped plates 327. In the normal state, the sliding rod 71 is located at the bottom of the sliding groove 3212, and the sliding groove 3212 is parallel to the central axis of the column 321. Therefore, when the first driving push rod 31 pushes the detection head 32 to move downward, the bottom end of the sliding rod 71 contacts the opening of the mounting hole and is restricted by the mounting hole. However, since the sliding rod 71 is slidably connected to the sliding groove 3212, the sliding rod 71 will be driven by the opening. When the sliding groove 3212 moves upward, the second main capacitor block 74 on the sliding rod 71 will move on the iron plate 72, and the second main capacitor block 74 is connected to the iron plate 72 by wire, and the second auxiliary capacitor block 73 is also connected to the iron plate 72 by wire. Therefore, when the sliding rod 71 moves, the distance between the second main capacitor block 74 and the second auxiliary capacitor block 73 will be shortened, so that the resistance value between the two will change. The farther the distance between the two is, the higher the resistance value is. Conversely, the closer the distance between the two is, the lower the resistance value is. The depth of the mounting hole can be known according to the changed resistance value.

[0048] like Figure 2 , Figure 3 As shown, the guide block 6 is bolted to the bottom plate 1 , a lower through hole 61 is provided in the middle of the guide block 6 , the lower through hole 61 is connected to the upper through hole 11 , and a laser indicator light 8 is provided outside the lower through hole 61 .

[0049] Specifically, the guide block 6 is located at the bottom end of the base plate 1, and the guide block 6 and the upper through hole 11 of the base plate 1 are on the same central axis. The guide block 6 is connected to the base plate 1 by bolts. When the guide block 6 is located at the bottom end of the base plate 1, its laser indicator light 8 is turned on, and the output end of the laser indicator light 8 is located above the mounting hole. The output end of the laser indicator light 8 is used to determine whether the detection head 32 is located above the mounting hole.

[0050] like Figure 1 As shown, a control terminal 9 is provided between the bottom plate 1 and the top plate 2 .

[0051] Specifically, a control panel is provided in the control terminal 9, and the difference generated by the first capacitor block 333 on the telescopic rod 331 will be reflected on the control panel, so that the staff can judge the inclination of the inner wall of the installation hole through the numerical value, and then the value of the first capacitor block 333 on the depth detection component 7 will also be reflected on the control panel. The control panel is electrically connected to the first driving push rod 31, and the control panel is electrically connected to the second driving push rod 52.

[0052] Working principle: The first driving push rod 31 is controlled to work through the control panel. After the first driving push rod 31 pushes the detection head 32 to move, the bottom end of the detection head 32 will contact the bottom end of the inner wall of the mounting hole, so that the extrusion block at the bottom end of the detection head 32 will be compressed and move upward. The movement of the extrusion block will drive the threaded column 323 to move upward. When the threaded column 323 moves, the inner bearing 324 in the bearing will rotate with the movement of the threaded column 323. When the inner bearing 324 rotates, it will drive one end of the connecting rod 326 to move in an arc shape. The other end of the connecting rod 326 will push the arc plate 327 to move outward, and the arc plate 327 will contact the inner wall of the mounting hole. When the arc plate 327 contacts the inner wall of the mounting hole, , the spring 332 will continue to apply force to push one end of the arc plate 327 to move toward the inner wall of the mounting hole, and then the first capacitor blocks 333 are provided at both ends of the telescopic rod 331. The inclination of the inner wall of the mounting hole and the inner diameter of the hole are judged according to the numerical values. At the same time, when the first driving push rod 31 pushes the detection head 32 to move downward, the bottom end of the sliding rod 71 contacts the opening of the mounting hole and is restricted by the mounting hole. The sliding rod 71 will be driven by the opening to move upward in the sliding groove 3212. During this period, the second main capacitor block 74 on the sliding rod 71 will move on the iron plate 72, so that when the sliding rod 71 moves, the distance between the second main capacitor block 74 and the second auxiliary capacitor block 73 will be shortened, and the depth of the mounting hole can be known according to the changed resistance value.

[0053] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
