Description

Technical Field

[0001] This application relates to the field of detection device technology, and in particular to a plate hole detection device. Background Technology

[0002] Opening holes in plate-like components is a common structural feature. For example, a plate-like component might be a tube sheet for a heat exchanger, with multiple sets of circular holes that mate with the heat exchanger tubes. The tubes pass through these holes, allowing the tube sheet to hold them in place and isolate the media on either side of the tube sheet. The size of the openings must match the dimensions of the mating components. For instance, if the holes in the tube sheet are too small, the heat exchanger tubes cannot pass through them; if the holes are too large, a large gap will appear between the holes and the heat exchanger tubes, affecting the sealing of the tube sheet to the media on both sides and causing a decrease in the heat transfer coefficient of the heat exchanger. Therefore, the size of the openings in plate-like components needs to be strictly controlled to ensure that the openings meet the mating requirements.

[0003] Because dimensional deviations can occur during the manufacturing process of openings, the dimensions of openings on plate-shaped parts typically need to be checked before installation to avoid rework and improve work efficiency. Directly measuring opening dimensions with calipers is prone to errors due to the skill level of the measuring personnel. Furthermore, measuring each opening individually with calipers results in low measurement efficiency. Utility Model Content

Detailed Implementation

[0025] To better understand the above technical solutions, the technical solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.

[0026] The first aspect of this application provides a plate hole detection device, such as... Figure 1As shown, the plate hole detection device is used to measure the size of the hole 21 to be measured. The hole 21 is located on the plate 20 to be measured. The plate hole detection device includes a clamping assembly 100 and a detection assembly 200. The clamping assembly 100 is used to clamp the plate 20 to be measured, and the detection assembly 200 is connected to the clamping assembly 100. The detection assembly 200 includes two detection plates 210 and a drive module 220. The detection plates 210 are used to extend into the hole 21 to be measured, and the drive module 220 can drive the two detection plates 210 to move toward or away from each other, so that the two detection plates 210 abut against the hole wall of the hole 21 to be measured.

[0027] In this embodiment, the test plate 20 can be a tube sheet of a heat exchanger, and the test hole 21 is used to mate with the tube body, which can be a heat exchange tube. The test hole 21 can be a through hole or a blind hole, and the shape of the test hole 21 can be circular, elongated, or polygonal. The size of the test hole 21 can be the diameter of a circle, the diagonal length of a polygon, or the distance between adjacent test holes 21.

[0028] The clamping assembly 100 secures the test plate 20 to prevent it from shifting and affecting the detection of the test hole 21. After clamping, the depth direction of the test hole 21 is the same as the extension direction of the detection plate 210 of the detection assembly 200. When detecting the size of the test hole 21, the detection plate 210 is inserted into the test hole 21. The drive module 220 drives the two detection plates 210 to move inward toward each other or outward toward each other. When both detection plates 210 reach the designated position, they abut against the hole wall of the test hole 21. The required size of the test hole 21 is obtained by measuring the distance between the two detection plates 210.

[0029] For example, two detection plates 210 can extend into the same test hole 21 and abut against the two side walls of the test hole 21 to detect the inner diameter of the test hole 21. The two detection plates 210 can also extend into two different test holes 21 and abut against the walls of the two test holes 21 respectively to detect the distance between the two test holes 21.

[0030] The clamping assembly 100 and the detection assembly 200 work together to improve the stability and accuracy of the detection. The drive module 220 moves the two detection plates 210, causing them to fit against the inner wall of the hole 21 to be tested, thus checking the size of the hole 21. This improves the convenience and accuracy of the detection, enabling rapid inspection, increasing detection efficiency, enhancing the automation of the detection operation, reducing the workload of manual operation, minimizing errors caused by manual operation, and improving the practicality of the device.

[0031] In some embodiments provided in this application, such as Figure 2 and Figure 3As shown, the detection assembly 200 also includes a display panel 230 and two transmission rods 240. The detection plate 210 is slidably connected to the display panel 230. Both ends of any transmission rod 240 are rotatably connected to the drive module 220 and the detection plate 210, respectively. The drive module 220 can drive the end of the transmission rod 240 to rotate so that the detection plate 210 moves radially along the hole to be tested 21.

[0032] In this embodiment, Figure 1 In the diagram, the arrow at point X points to the radial direction of the hole 21 to be tested. The radial direction of the hole 21 to be tested can be horizontal. The detection plate 210 can slide on the display plate 230 along the radial direction of the hole 21 to be tested. The two ends of the transmission rod 240 are rotatably connected to the drive module 220 and the detection plate 210 respectively through the rotating shaft, so that the transmission rod 240 and the detection plate 210 form a crank-slider structure. Figure 3 The middle arrow indicates the direction of movement of the transmission rod 240 and the detection plate 210. When the drive module 220 is in operation, one end of the transmission rod 240 rotates with the drive module 220, while the other end drives the detection plate 210 to slide radially along the test hole 21 on the display plate 230, causing the two detection plates 210 to move closer or further apart. The transmission rod 240 enables the mutual conversion between rotary motion and reciprocating linear motion, resulting in efficient energy conversion, improved transmission efficiency, simple structure, low manufacturing and maintenance costs, and ease of maintenance and repair.

[0033] For example, the display panel 230 is provided with a groove, and the detection plate 210 is provided with a protrusion. The protrusion cooperates with the groove, allowing the detection plate 210 to slide along the extension direction of the groove. A numerical scale is provided on the side of the display panel 230 near the detection plate 210. The numerical scale is used to indicate the distance between the two detection plates 210. By observing the numerical scale, the size of the hole 21 to be tested can be obtained, improving the convenience of observing the test results.

[0034] In some embodiments provided in this application, such as Figure 2 As shown, the drive module 220 includes a drive shaft 221, an operating member 222, and a rotating block 223. The operating member 222 is connected to the top of the drive shaft 221, and the rotating block 223 is connected to the bottom of the drive shaft 221. Both ends of the rotating block 223 extend radially out of the drive shaft 221, and both ends of the rotating block 223 are rotatably connected to two transmission rods 240.

[0035] In this embodiment, the drive shaft 221 has an operating member 222 and a rotating block 223 at both ends. The operator can hold the top operating member 222, improving operational convenience. The rotating block 223 extends radially outward from the drive shaft 221. The drive shaft 221 rotates with the operating member 222, causing the rotating block 223 below to rotate around the axis of the drive shaft 221, which in turn drives the transmission rods 240 at both ends to rotate, thereby driving the detection plate 210 to slide. By providing the outwardly extending rotating block 223, the rotation range of the drive module 220 is expanded, thereby increasing the rotation amplitude of the transmission rods 240, giving the detection plate 210 a sufficient range of motion and improving the rationality of the transmission layout.

[0036] For example, the operating element 222 may be a handwheel or a lever.

[0037] In some embodiments provided in this application, such as Figure 1 and Figure 4 As shown, the plate hole detection device also includes an adjustment component 300, which is connected to the clamping component 100. The adjustment component 300 includes a slider 310, a stud 320, and a drive component 330. The slider 310 is connected to the detection component 200. The stud 320 extends along the height direction of the plate to be tested 20. The slider 310 is threadedly connected to the stud 320. The drive component 330 can drive the stud 320 to rotate, so that the slider 310 moves along the axial direction of the stud 320.

[0038] In this embodiment, Figure 1 The arrow at position Y points to the height direction of the test plate 20, which can be vertical. The stud 320 extends along the height direction of the test plate 20. The slider 310 has an internal thread, and the slider 310 and the stud 320 are connected by the thread, forming a lead screw structure. The driving component 330 can be a motor, which is connected to the stud 320. When the driving component 330 drives the stud 320 to rotate, it causes the slider 310 to move up or down along the axis of the stud 320. The detection component 200 moves up and down with the slider 310 to adjust the height of the detection component 200, which facilitates the detection of the size of the test hole 21 at different heights, expands the detection range of the detection component 200, and improves the adaptability of the plate hole detection device.

[0039] For example, the top of the stud 320 is provided with a positioning plate 370, which extends radially along the stud 320 to define the movement position of the slider 310.

[0040] In some embodiments provided in this application, such as Figure 2As shown, the adjustment assembly 300 also includes an adjustment plate 340 and an adjustment column 350. The adjustment plate 340 is connected to the slider 310. The adjustment plate 340 is provided with an adjustment hole 341. The adjustment column 350 passes through the adjustment hole 341. The first end of the adjustment column 350 extends out of the adjustment plate 340 and is connected to the detection assembly 200. The adjustment column 350 can adjust the distance by which the first end extends out of the adjustment plate 340.

[0041] In this embodiment, after the test plate 20 is clamped, the axial direction of the adjusting column 350 is the same as the depth direction of the test hole 21. The adjusting column 350 passes through the adjusting hole 341 of the adjusting plate 340, so that both ends of the adjusting column 350 extend out of the adjusting hole 341. The first end of the adjusting column 350 extends out of the adjusting plate 340 and connects to the detection assembly 200. During detection, the distance of the first end of the adjusting column 350 extending out of the adjusting plate 340 is reduced, so that the adjusting detection moves towards the test plate 20, and the detection plate 210 extends into the test hole 21. After the detection is completed, the distance of the first end of the adjusting column 350 extending out of the adjusting plate 340 is increased, so that the adjusting detection moves away from the test plate 20, and the detection plate 210 retracts out of the test hole 21. By adjusting the position of the first end, the position of the detection plate 210 relative to the test hole 21 can be adjusted, improving the convenience and accuracy of detection and increasing detection efficiency.

[0042] For example, the top wall of the adjusting column 350 is connected to the bottom wall of the positioning plate 370.

[0043] For example, the detection assembly 200 also includes a connecting frame 250, with an adjustment plate 340 connected to the top of the connecting frame 250 and the bottom of the connecting frame 250 connected to the display panel 230.

[0044] In some embodiments provided in this application, such as Figure 2 As shown, the adjusting hole 341 is an elongated hole that extends along the axial direction of the stud 320, and the adjusting pin 350 can move within the adjusting hole 341.

[0045] In this embodiment, the structure of the adjustment hole 341 is further defined. The adjustment hole 341 extends along the height direction, and the adjustment column 350 can move within the adjustment hole 341 to adjust the height of the adjustment column 350. The height of the detection component 200 can be further adjusted through the adjustment hole 341, making the detection height more accurate, improving the flexibility of detection, and improving the convenience and accuracy of plate hole detection.

[0046] In one embodiment, the inspector adjusts the inspection height by holding the adjustment column 350. When the adjustment column 350 is in the inspection position, the driving inspection plate 210 abuts against the inner wall of the hole to be tested 21, and the inspection component 200 is fixed by the abutment force, thereby fixing the position of the adjustment column 350.

[0047] In another embodiment, the second end of the adjusting column 350 is provided with a limiting member. The adjusting column 350 may be provided with threads, and the limiting member may be a nut or a limiting pin. When the adjusting column 350 is in the detection position, the limiting member is engaged with the adjusting plate 340 to fix the adjusting column 350.

[0048] In some embodiments provided in this application, such as Figure 4 As shown, the adjustment assembly 300 also includes a guide post 360, which is connected to the clamping assembly 100. The guide post 360 extends along the axial direction of the stud 320 and passes through the slider 310. The slider 310 is slidably connected to the guide post 360. The outer wall of the guide post 360 is provided with a scale.

[0049] In this embodiment, the guide post 360 extends along the height direction, and the slider 310 is provided with a through hole. The guide post 360 passes through the through hole, allowing the slider 310 to slide up and down along the axial direction of the guide post 360. The guide post 360 guides the sliding movement, making the movement of the slider 310 more stable and improving the stability of the lifting and lowering of the detection component 200.

[0050] For example, there are two guide posts 360, which are located at the two ends of the slider 310 respectively.

[0051] The outer wall of the guide post 360 is equipped with a scale, which is used to indicate the position of the slider 310. By observing the scale, the height of the slider 310 can be obtained, and thus the height of the detection component 200 can be obtained. When the test plate 20 is a circular plate, the outer diameter of the test plate 20 can be obtained by the scale, which improves the convenience of observing the detection results.

[0052] In some embodiments provided in this application, such as Figure 1 As shown, the clamping assembly 100 includes: a base plate 110, the test plate 20 can be clamped on the base plate 110, and the end of the base plate 110 is provided with a slope 111, the slope 111 makes the thickness of the base plate 110 gradually decrease.

[0053] In this embodiment, during the clamping operation, the test plate 20 is placed on the base plate 110. The top surface of the base plate 110 is provided with an inclined surface 111. The distance between the inclined surface 111 and the bottom surface of the base plate 110 gradually decreases, so that the thickness of the base plate 110 near the edge gradually decreases. When the test plate 20 has a smooth shape, it can be rolled onto the base plate 110 along the inclined surface 111, which improves the convenience of clamping the test plate 20, reduces the workload of manual operation, and improves the clamping efficiency.

[0054] For example, the drive unit 330 is disposed on the base plate 110, and the bottom of the guide post 360 is connected to the base plate 110.

[0055] In some embodiments provided in this application, such as Figure 5 As shown, the clamping assembly 100 also includes: two limiting blocks 120, a sleeve 130, two connecting rods 140 and an elastic element 150. The two limiting blocks 120 are respectively used to abut the two ends of the receiving plate 20. The sleeve 130 is connected to the base plate 110. The two connecting rods 140 are respectively located on both sides of the sleeve 130. One end of any connecting rod 140 is connected to the limiting block 120, and the other end extends into the sleeve 130 and is slidably connected to the sleeve 130. The two ends of the elastic element 150 are respectively connected to the limiting block 120 and the sleeve 130.

[0056] In this embodiment, the sleeve 130 is connected to the stud 320 or the guide post 360, so that the sleeve 130 is connected to the base plate 110 through the stud 320 or the guide post 360. The two sides of the sleeve 130 are slidably connected to two connecting rods 140 respectively. The elastic element 150 generates elastic deformation when the connecting rods 140 slide outward, causing the connecting rods 140 to move towards each other. For example, the elastic element 150 can be a spring.

[0057] When clamping the test plate 20, firstly, the two limiting blocks 120 are pulled out in the direction of separation from each other. The limiting blocks 120 drive the connecting rods 140 on both sides to slide away from the sleeve 130. Then, the test plate 20 is placed between the two limiting blocks 120. Under the pull of the elastic element 150, the connecting rods 140 move in the direction of approaching each other, and drive the two limiting blocks 120 to abut against the two ends of the test plate 20 respectively, thus completing the clamping operation and fixing the test plate 20 on the base plate 110. This improves the stability of the test plate 20 during testing and increases the accuracy of the testing. Furthermore, the clamping assembly 100 can adapt to test plates 20 of different sizes, increasing the applicability of the plate hole detection device.

[0058] For example, there is one sleeve 130, and the middle of the sleeve 130 is connected to the stud 320 or the guide post 360. Alternatively, there are two sleeves 130, and the clamping assembly 100 also includes a fixing block 180, with the two ends of the fixing block 180 respectively connected to the two sleeves 130, and the fixing block 180 is connected to the stud 320 or the guide post 360.

[0059] In some embodiments provided in this application, such as Figure 5 As shown, the clamping assembly 100 also includes a mounting plate 160 and a support rod 170. The mounting plate 160 is used to place on the operating platform, and the two ends of the support rod 170 are respectively connected to the sleeve 130 and the mounting plate 160.

[0060] In this embodiment, one end of the support rod 170 is connected to the sleeve 130 to provide structural support for the sleeve 130 and improve the stability of the clamping assembly 100. The other end of the support rod 170 is connected to the mounting plate 160, the bottom surface of which is located on the operating platform, increasing the contact area between the operating platform and the support rod 170 and improving the stability of the support. The bottom surface of the mounting plate 160 is coplanar with the bottom surface of the base plate 110, which is used to place on the operating platform. The operating platform can be the ground or the surface of the operating bed.

[0061] For example, there may be two support rods 170, located on either side of the stud 320. The extension direction of the support rod 170 forms a support angle with the height direction to improve the stability of the support rod 170. Alternatively, the support rod 170 and the mounting plate 160 may be constructed of angle steel.

[0062] In one specific embodiment, a tooling (i.e., plate hole detection device) for quickly checking the size of tube sheet holes in a heat exchanger is provided. A connecting frame 250 is movably connected to one side of an adjusting plate 340. The connecting frame 250 is connected to bolts (i.e., adjusting column 350). A movable plate (i.e., display plate 230) is connected to the bottom of the connecting frame 250. A control rod (i.e., drive shaft 221) is rotatably connected inside the movable plate. A rotating block 223 is connected to the outer wall of the control rod. Both ends of the rotating block 223 are rotatably connected to a transmission rod 240 through shafts set inside it. The transmission rod 240 is rotatably connected to a detection plate 210 through shafts set inside it. The outer wall of the detection plate 210 is movably connected to the tube sheet body (i.e., the plate to be tested 20). By rotating the control rod and connecting the rotating block 223, the two sets of transmission rods 240 are driven to rotate, causing the two sets of transmission rods 240 to drive the detection plate 210 to tighten inward or expand outward to fit the inner wall of the tube sheet hole (i.e., the hole to be tested 21) and check the inner diameter of the tube sheet hole. By rotating the bolts, the connection between the connecting bracket 250 and the adjusting plate 340 can be released, so as to adjust the distance between the two. This helps the device to be adjusted according to the actual height of the tube sheet hole, thereby enhancing the accuracy of the device's detection.

[0063] The adjusting plate 340 has an internal movable groove and is threaded to a bolt. One end of the bolt passes through the interior of the connecting frame 250. A numerical table is provided on the side of the moving plate near the detection plate 210. The inner diameter of the tube sheet hole is detected by observing the numerical table.

[0064] The bottom of the tube sheet body is connected to a base plate 110. Both sides of the base plate 110 are provided with inclined surfaces 111. The base plate 110 is connected to a drive component 330. The output end of the drive component 330 is connected to a stud 320. The stud 320 is threadedly connected to a slider 310. One side of the slider 310 is connected to the outer wall of the adjusting plate 340. The top of the stud 320 is connected to a positioning plate 370. The drive component 330 drives the stud 320 to rotate, causing the slider 310 to move up and down until it is in contact with the top of the tube sheet body, so as to detect the outer diameter of the tube sheet body at different heights.

[0065] Both ends of the slider 310 are movably connected to guide posts 360. The bottom of the guide post 360 is connected to the top of the base plate 110. A numerical table is set on the outer wall of the guide post 360. The outer wall of the guide post 360 is connected to a fixing block 180. When the slider 310 moves, it moves up and down along the guide post 360 to ensure the stability of the device.

[0066] The interior of the fixing block 180 is threaded to the outer wall of the stud 320. Sleeves 130 are fixedly connected to both sides of the fixing block 180. A connecting rod 140 is movably connected inside the sleeve 130. An elastic element 150 is fixedly connected to one side of the sleeve 130, and a limiting block 120 is fixedly connected to one side of the elastic element 150. One side of the limiting block 120 is connected to one side of the connecting rod 140. When the tube sheet body is placed on one side of the sleeve 130, the limiting block 120 is pushed to expand to both sides, stretching the connecting elastic element 150 and causing the connecting rod 140 to move inside the sleeve 130. The tension of the elastic element 150 itself causes the limiting block 120 to contract inward, thus limiting and fixing the tube sheet body. Support rods 170 are fixedly connected to the outer walls of both sets of sleeves 130. A mounting plate 160 is fixedly connected to the bottom of the support rod 170. The tube sheet body is supported and fixed by the sleeves 130 connected to the support rods 170.
