[0003] In the prior art, traditional detection methods include calipers, gauges, three-coordinate measuring machines, etc. Calipers and gauges require manual operation to measure each hole, so the operation is tedious and inefficient, and errors can easily occur due to human factors. Although three-coordinate measuring machines have high precision, they take a long time to detect multi-hole parts, affecting production efficiency. In addition, the above-mentioned traditional detection methods are mostly qualitative detection, which is difficult to analyze data in depth and cannot meet the requirements of product detection in a digital manufacturing environment.

[0004] Therefore, there is an urgent need for a multi-hole position disposable size detection mechanism to achieve rapid and accurate detection of multi-hole workpieces, improve detection efficiency and quality, reduce production costs, and meet the needs of modern manufacturing for efficient and automated detection. SUMMARY

[0005] Therefore, the utility model provides a kind of multi-hole position disposable size detection mechanism to solve above-mentioned problem.

[0006] A multi-hole position disposable size detection mechanism includes a mounting beam, a detection mechanism fixedly arranged on the mounting beam, and a lifting base arranged on one side of the detection mechanism. The detection mechanism includes a mounting plate fixedly arranged on the mounting beam, a sensing plate assembly fixedly arranged on one side of the mounting plate, and a detection plate assembly fixedly arranged on one side of the sensing plate assembly. The sensing plate assembly includes a plurality of guide columns fixedly connected to the mounting plate, a sensing plate movably sleeved on the plurality of guide columns, and a sensor arranged in the middle of the sensing plate. The detection plate assembly includes a detection plate located on the side of the sensing plate opposite to the mounting plate, two pin barrels fixedly arranged on both sides of the detection plate, two pins fixedly arranged on the sensing plate, and two springs respectively accommodated in the pin barrels. The guide columns are fixedly connected to the mounting plate. The sensing plate is movably sleeved on the guide columns. One end of the pin is fixedly connected to the sensing plate, and the other end of the pin is inserted into the pin barrel.

[0007] Further, the detection plate assembly further includes a balance column.

[0008] Further, a through hole is arranged on the induction plate corresponding to the balancing column, one end of the balancing column is fixed on the detection plate, and the other end is inserted into the through hole.

[0009] Further, the lifting base includes a platform and a workpiece accommodating groove arranged on the platform.

[0010] Further, the structure of the side of the detection plate facing the lifting base is specifically arranged according to the structure of the workpiece to be detected, so that the detection plate can be attached to the surface of the workpiece during detection.

[0011] Further, the detection plate is made of plastic material.

[0012] Further, the openings at both ends of the pin barrel are matched with the diameter of the pin.

[0013] Further, the number and position of the pins are arranged according to the number and position of the openings of the workpiece to be detected.

[0014] Compared with the prior art, the multi-hole disposable size detection mechanism provided by this utility model includes the detection mechanism and the lifting base.

One end of the needle is fixedly connected to the sensing plate, and the other end is inserted into the needle cylinder. During detection, the workpiece to be detected is placed on the lifting base, and then the lifting base is driven to move upward, pushing the detection plate upward, thereby compressing the springs and causing the needles to extend. When the opening of the workpiece meets the requirements, the pin can be inserted into its opening without pushing the sensing plate upwards, and the distance between the sensing plate and the mounting plate remains unchanged. When the opening of the workpiece does not meet the requirements, the pin abuts against the end face of the workpiece, thereby pushing the sensing plate upwards, causing a change in the distance between the sensing plate and the mounting plate.

[0016] Figure 2 for Figure 1 A cross-sectional structural diagram of the detection plate in a multi-hole, one-time dimensional detection mechanism. Detailed Implementation

[0017] The specific embodiments of this utility model will be described in further detail below. It should be understood that the description of this utility model herein is not intended to limit the scope of protection of this utility model.

[0018] like Figures 1 to 2As shown, it is the structure schematic view of the multi-hole disposable size detection mechanism provided by the utility model. The multi-hole disposable size detection mechanism includes an installation beam 10, a detection mechanism 20 fixedly arranged on the installation beam 10 and a lifting base 30 arranged on one side of the detection mechanism 20. It is conceivable that the multi-hole disposable size detection mechanism should also include some other related functional components, such as mounting components, assembly components and the like, which are all prior art known to those skilled in the art and will not be described here.

[0019] It is conceivable that the multi-hole disposable size detection mechanism should be supported by a support frame (not shown) and assembled into a whole that cooperates with each other. The installation beam 10 can be part of the support frame, and it is arranged horizontally for fixing the detection mechanism 20. The installation beam 10 itself should be a kind of prior art, and will not be described here.

[0020] The detection mechanism 20 includes an installation plate 21 fixedly arranged on the installation beam 10, an induction plate assembly 22 fixedly arranged on one side of the installation plate 21 and a detection plate assembly 23 fixedly arranged on one side of the induction plate assembly 22.

[0021] The installation plate 21 can be a square plate body for fixing the induction plate 22. At least one fixing screw hole is arranged on the installation plate 21. The fixing screw hole is used to fix the installation plate 21 on the installation beam 10. And the fixing screw hole is arranged on the central axis of the installation plate 21 parallel to the installation beam 10. When there is only one fixing screw hole, it is arranged at the center of the installation plate 21 to ensure the stability of the installation plate 21. Connection holes for connecting the induction plate assembly 22 are arranged at the four corners of the installation plate 21, so that the induction plate assembly 22 can be fixedly arranged on the side of the installation plate 21 opposite to the installation beam 10 through the connection holes.

[0022] The induction plate assembly 22 includes a plurality of guide columns 221 fixedly connected to the installation plate 21, an induction plate 222 movably sleeved on the plurality of guide columns 221 and a sensor 223 arranged in the middle of the induction plate 222.

[0023] One end of the guide column 221 is fixedly connected to the installation plate 21, and the other end is inserted into the through hole of the induction plate 222. The guide column 221 is used to install the induction plate 222 on the fixed plate 21 and guide the axial up and down movement of the induction plate 222. The end of the guide column 221 arranged the induction plate 222 can be fixed and limited by a nut.

[0024] The sensing plate 222 has an "I"-shaped structure. Multiple through holes are symmetrically arranged on the upper part of the sensing plate 222, matching the guide post 221. The sensing plate 222 can be slidably mounted on one end of the guide post 221 through these through holes.

[0025] The sensor 223 is fixedly mounted in the middle of the sensing plate 222. The sensor 223 can be a laser sensor or other sensor that is advantageous for short-range detection and has a fast response. The sensor 223 is used to detect the distance between the sensing plate 222 and the fixed plate 21. It is conceivable that the detection mechanism should also be equipped with a receiver for receiving the sensing signal from the sensor 223, and a processing system for processing the received information. The receiver and the processing system themselves are existing technologies and will not be described in detail here.

[0026] The detection plate assembly 23 includes a detection plate 231 located on the side opposite to the sensing plate 222 and the mounting plate 21, two needle tubes 232 fixedly disposed on both sides of the detection plate 231, two needles 233 fixedly disposed on the sensing plate 222, two springs 234 respectively housed in the needle tubes 232, and a balance column 235 disposed on one side of the needles 233.

[0027] The detection plate 231 is horizontally positioned on the side facing the sensing plate 222, while the structure on the side facing the lifting base 30 can be specifically configured according to the structure of the workpiece to be detected, so that it can fit against the surface of the workpiece during detection. The detection plate 231 can be injection molded from plastic material.

[0028] The needle insert cylinder 232 can be formed by rolling a thin metal sheet, such as an iron sheet, into a cylindrical shape. The needle insert cylinder 232 can be injection molded into the detection plate 231, serving to house the spring 234 and facilitating the passage of the needle 233. Both ends of the needle insert cylinder 232 are folded inwards to facilitate support of the spring 234. The diameter of the folded opening of the needle insert cylinder 232 is matched to the diameter of the needle 233, thus preventing a large gap from forming between the needle insert cylinder 232 and the needle 233. This would prevent the detection plate 231 from moving back and forth radially in the direction of the needle 233, leading to misalignment of the needle 233 with the opening of the workpiece during detection, resulting in false detections. The position and number of the needle insert cylinders 232 are matched to the position and number of the needles 233.

[0029] The number of the pins 233 is set according to the number of holes to be detected on the workpiece to be detected, and the positions of the pins 233 are set corresponding to the positions of the holes on the workpiece. In the embodiment, two pins 233 are provided, and one end of each of the pins 233 is fixedly connected to the sensing plate 231, and the other end is coaxially inserted into the pin barrel 232. The diameter of the pin 233 is matched with the diameter of the hole to be detected on the workpiece.

[0030] The spring 234 is accommodated in the pin barrel 232, one end of the spring 234 abuts against one side of the pin barrel 232 facing the lifting base 30, and the other end abuts against one side of the pin barrel 232 facing the sensing plate 222 and is fixed to the pin 233. When the lifting base 30 pushes the detection plate 231 upward, the spring 234 is compressed by force, so that the detection plate 231 moves upward. At the same time, during the movement, the end face of the detection plate 231 on the side facing the lifting base 30 can always be attached to the end face of the workpiece to be detected under the action of the elasticity of the spring 234, so that relative displacement between the detection plate 231 and the workpiece to be detected during the movement is avoided, which causes detection error. The size and dimension of the spring 234 can be set according to the length of the pin 233 to be probed. Specifically, the height of the tip of the free end of the pin 233, i.e. the end facing the lifting base 30, from the outlet end face of the pin barrel 232 on the side facing the lifting base 30 is h1. The depth of the hole to be detected on the workpiece is h2. When the spring 234 is in the uncompressed state, the height difference between the detection plate 231 and the sensing plate 222 is h3. The compressible distance of the spring 234 is the sum of h1 and h2, and h1 is equal to h3. Therefore, when the lifting base 30 pushes the detection plate 231 upward by h1, the tip of the pin 233 is probed to contact the end face of the workpiece to be detected, and since h1 is equal to h3, the detection plate 231 is attached to the sensing plate 222 at this time. When the lifting base 30 continues to rise by h2, if the hole opened on the workpiece meets the requirements, under the pushing of the lifting base 30, the detection plate 231 moves upward to continue to compress the spring 234 by h2, and the pin 233 is probed to be inserted into the hole of the workpiece. On the contrary, if the size of the hole of the workpiece is too small or the position is not correct, the pin 233 will abut against the end face of the workpiece, so that the sensing plate 222 is pushed to move upward by h2. At this time, the sensor 223 can detect the distance change between the sensing plate 222 and the fixed plate 21, and output sensing information, and the information processing system can determine whether the hole of the workpiece meets the requirements according to the distance change between the sensing plate 222 and the fixed plate 21.

[0031] The balance column 235 is mainly used to maintain the stability and balance of the detection plate 231, and the number and position thereof can be adjusted according to the number and position of the pins 233. In the embodiment, since the two pins 233 are respectively arranged on the two sides of the detection plate 231 and are asymmetric, the balance column 235 is arranged to ensure the stability and levelness of the detection plate 231. A through hole is arranged on the induction plate 222 corresponding to the balance column 235, one end of the balance column 235 is fixedly connected with the detection plate 231, and the other end is inserted into the through hole. When the detection plate 231 moves upward, the end of the balance column 235 will extend out of the through hole, thereby forming a gap to avoid pushing the induction plate 222 to move upward.

[0032] The lifting base 30 comprises a base plate 31 and a workpiece accommodating groove 32 arranged on the base plate 31.

[0033] The base plate 31 can be a square plate body, which is used to support the workpiece to be detected. It is conceived that a driving device (not shown), such as a pneumatic cylinder, for driving the base plate to move up and down should be arranged on the side of the base plate 31 opposite to the detection mechanism. The driving device itself is a prior art, which will not be described in detail here.

[0034] The workpiece accommodating groove 32 is arranged on the base plate 31 corresponding to the detection plate 231, and the size and structure thereof are matched with the workpiece to be detected. The workpiece accommodating groove is used to accommodate the workpiece to be detected and fix the position of the workpiece, so as to avoid the displacement of the workpiece placed directly on the base plate 31, which is not conducive to detection.

[0035] Compared with the prior art, the multi-hole one-time size detection mechanism has the detection mechanism 20 and the lifting base 30. The detection mechanism 20 comprises an installation plate 21 fixed on the installation beam 10, an induction plate assembly 22 fixed on one side of the installation plate 21, and a detection plate assembly 23 fixed on one side of the induction plate assembly 22. The induction plate assembly 22 comprises a plurality of guide columns 221 fixedly connected to the installation plate 21, an induction plate 222 movably sleeved on the plurality of guide columns 221, and a sensor 223 arranged in the middle of the induction plate 222. The detection plate assembly 23 comprises a detection plate 231 located on the side, away from the installation plate 21, of the induction plate 222, two insertion pin barrels 232 fixedly arranged on the two sides of the detection plate 231, two insertion pins 233 fixedly arranged on the induction plate 222, two springs 234 respectively accommodated in the insertion pin barrels 232, and a balance column 235 arranged on one side of the insertion pin 233. One end of the insertion pin 233 is fixedly connected to the induction plate 222, and the other end is inserted into the insertion pin barrel 232. When detection is performed, the workpiece to be detected is placed on the lifting base 30, then the lifting base 30 is driven to move upwards, and the detection plate 231 is pushed to move upwards, so that the spring 234 is compressed and the insertion pin is exposed. When the opening of the machined workpiece meets the requirements, the insertion pin 233 can be inserted into the opening, and the induction plate 222 cannot be pushed to move upwards, and the distance between the induction plate 222 and the installation plate 21 cannot be changed. When the opening of the workpiece does not meet the requirements, the insertion pin 233 abuts against the end face of the workpiece, thereby pushing the induction plate 222 to move upwards, so that the distance between the induction plate 222 and the installation plate 21 is changed. Therefore, the information processing system can judge the opening machining of the workpiece according to the data detected by the sensor 223. In summary, the multi-hole one-time size detection mechanism can not only automatically detect a plurality of hole positions at one time, but also facilitate data analysis and statistics, improve the detection efficiency, and reduce the production cost, thereby meeting the needs of modern manufacturing for efficient and automatic detection.

[0036] The above is only a preferred embodiment of the utility model, and is not used for limiting the protection scope of the utility model, and any modification, equivalent replacement or improvement within the utility model spirit is covered in the utility model claim scope.
