Description

Technical Field

[0001] The invention relates to the technical field of end plate detection, and in particular to a track-type end plate dimension runout detection device. Background Art

[0002] The existing end plate detection device is a precision equipment specially used to detect the dimensional runout of track-type end plates. Its main function is to accurately measure the dimensional deviation and runout at different positions on the end plate surface to ensure that the dimensional accuracy of the end plate meets the relevant standards and usage requirements.

[0003] However, the existing technology still has the following defects when used specifically: 1. The existing technology uses a laser scanner to emit a laser beam to scan the surface of the end plate, and obtains the three-dimensional shape data of the end plate surface based on information such as the time or phase of the reflected light. However, the data processing obtained by laser scanning is relatively complicated, and the scanning data needs to be converted into size and runout information through complex algorithms to obtain the results. Although this method can obtain a large amount of data, it lacks a simple and direct reference standard. It simply obtains the point cloud data of the surface, and subsequent complex data processing and algorithm analysis are required to obtain the end flatness tolerance.

[0004] 2. In addition, when performing dimensional runout detection in the prior art, it is necessary to reasonably plan the measurement path. For circular end plates, the method of equidistant measurement points on the circumference is generally adopted. The number of measurement points is determined according to the size and precision requirements of the end plates. For example, for end plates with larger diameters and higher precision requirements, multiple measurement points need to be evenly set. For square or other shaped end plates, it is necessary to ensure that the measurement points cover the key parts of the end plates, including edges, corners, etc. In order to achieve equidistant measurement points on the circumference or fully cover the measurement of key parts, it is necessary to assist in planning hundreds of measurement points on the surface of the end plate. Each measurement point requires the sensor to stay for a certain period of time for data collection, thereby greatly increasing the time cost of the entire measurement process.

[0005] 3. At the same time, in order to make up for the consumption of test time in the prior art, the measuring speed of the tester will be increased. If the measuring speed is too fast, for contact measurement, the measuring probe will vibrate on the surface of the end plate, resulting in fluctuations in the measurement data. Since the vibration is generated randomly, it is difficult to maintain consistency in the contact state between the probe and the surface of the end plate each time the measurement is made. The data fluctuation caused by this vibration will completely conceal the actual dimensional jump, causing the measurement result to deviate seriously from the actual value. For non-contact measurement, such as measurement using light, a too fast measurement speed will make the laser sensor unable to capture the signal on the surface of the end plate in a timely and accurate manner, which will lead to the omission of some signals, resulting in an inaccurate description of the surface features of the end plate, affecting the measurement results of the dimensional jump.

[0006] In view of this, the present invention proposes a track-type end plate dimension runout detection device to make up for and improve the deficiencies of the prior art. Summary of the invention

[0007] In order to solve the above technical problems, the present invention provides a track-type end plate dimension runout detection device to solve the technical problems raised in the above background technology.

[0008] In order to achieve the above purpose, the technical solution adopted by the present invention is: a track-type end plate size runout detection device, which is used to perform comprehensive size detection and processing on the end plate body, including a detection main frame, a controller is installed inside the detection main frame, a detector is installed on the lower surface of the controller, a drive assembly is symmetrically installed inside the detection main frame, an end surface detection mechanism is arranged on the side wall of the drive assembly, and an auxiliary self-test mechanism is arranged inside the detection main frame.

[0009] The end surface detection mechanism is used for the dimensional runout detection of the end flatness tolerance, so that the detection results of the end plate body can be intuitively displayed.

[0010] The auxiliary self-test mechanism is used to control the measuring speed of the end plate body and rationally plan the measuring path.

[0011] Furthermore, the end face detection mechanism includes an auxiliary instrument installed on the lower surface of the controller, a camera is installed on the outer wall of the right track in the driving assembly, a display mainboard is fixedly connected to the outer wall of the left track in the driving assembly, and a transparent lens is slidably connected to the surface of the display mainboard.

[0012] Furthermore, the auxiliary instrument and the detector are both electrically controlled by a controller, the auxiliary instrument and the detector are located in the same vertical plane, the detector corresponds to the eccentric position of the end plate body, and the auxiliary instrument and the end plate body are in a separated and staggered state.

[0013] Furthermore, the camera, the display mainboard and the transparent lens are all located in the same horizontal plane, and the transparent lens corresponds to the exact center position of the display mainboard and the camera respectively.

[0014] Furthermore, the transparent lens is a convex lens which is thick in the middle and thin at the edge. The side wall of the display mainboard is evenly provided with wire grooves corresponding to the position of the transparent lens. The center of the wire grooves is parallel to the light from the output end of the detector and the auxiliary instrument.

[0015] Furthermore, the auxiliary self-test mechanism includes a driving cylinder inside the detection main frame, the output shaft end of the driving cylinder is fixedly connected to a ring shaft, the outer wall of the ring shaft is installed with a linkage shell, the outer wall of the linkage shell is fixedly connected to a branch turntable, the upper surface of the branch turntable is slidably connected to a bearing base, a reset spring is installed inside the bearing base, and the two sides of the bearing base are symmetrically slidably connected to the folding bin.

[0016] Furthermore, the driving cylinder is electrically connected to the controller, the driving cylinder is intermittently reciprocating and telescopically moving, and the ring shaft is located at the top of the output end of the driving cylinder.

[0017] Furthermore, the outer wall of the ring shaft is evenly and fixedly connected with cylindrical protrusions, the inner wall of the linkage shell is provided with continuous inclined grooves at positions corresponding to the cylindrical protrusions, and the ring shaft and the linkage shell are rotationally connected through the cylindrical protrusions and the inclined grooves.

[0018] Furthermore, two ends of the return spring are fixedly connected to the branch turntable and the bearing base respectively, and the return spring is initially kept in a compressed state.

[0019] Furthermore, the folding bin is composed of two incomplete circular shells, and the folding bins are initially in a state of being away from each other.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) The device utilizes auxiliary light to maintain parallelism with the detection light, and installs a display mainboard on the side wall of the detection light and the auxiliary light irradiation end, thereby providing an intuitive reference system for detection. Through the reference constructed by this parallel relationship, when the irradiation path of the detection light is slightly offset, the coincidence state with the auxiliary light can be broken. By utilizing this intuitive visual presentation of whether the light coincides or not, the flatness tolerance of the detection is end-faceted, so that it forms an obvious fluctuation trajectory, and then the fluctuation difference can be intuitively detected by taking pictures, which greatly improves the intuitiveness of the detection. There is no need to rely on complex algorithms to interpret a large amount of data to determine whether there is a dimensional abnormality like traditional laser scanning.

[0021] Among them, setting a wire groove in the center of the display motherboard surface and associating it with the light provides a precise reference position for detection. By observing whether the detection light is offset to the left or right side of the wire groove, the surface defects of the end plate can be accurately judged, thereby avoiding unnecessary inspection and processing of the entire motherboard, and providing more targeted information for subsequent repairs or quality improvement measures.

[0022] Compared with the data analysis test results in traditional technologies, the auxiliary line comparison method used in this device has the following advantages: First, the end flatness tolerance can be intuitively detected by using a camera to capture the situation where two light rays do not overlap, and complex dimensional runout detection can be directly converted into simple visual judgment. This intuitive detection method helps to reduce the errors and uncertainties caused by complex algorithms and improves the reliability of the test results.

[0023] Second: Through intuitive light detection and camera capture, this simplified data processing method can significantly shorten the detection time and improve detection efficiency under the rapid detection requirements of industrial production. In an automated production line, rapid detection can enable products to enter the next process faster, thereby improving the rhythm of the entire production line.

[0024] Third: Relying on the intuitive comparison of light overlap results, it reduces the requirements for detection equipment and operator technical level to a certain extent. For some small and medium-sized enterprises, this detection method is easier to implement and promote, which helps to improve the detection level and product quality control capabilities of the entire industry.

[0025] (2) The device relies on the regular intermittent rotation of the supporting base to keep the rotation angle consistent each time. There is no need to perform complex end plate surface path planning before detection. This method directly skips the tedious planning steps, greatly saving time and improving the overall efficiency of detection. For end plates with irregular shapes, the device does not rely on specific measurement point planning and can more flexibly adapt to end plates of different shapes. Whether it is a round, square or other irregularly shaped end plate, it can be fully detected through this rotation method without the need to redesign the measurement point planning scheme for different shapes.

[0026] Compared with the auxiliary planning in the prior art, this device only needs to adjust the motion parameters of the driving cylinder (such as rotation angle, rotation speed, etc.) to quickly adjust the detection parameters according to actual needs, and through the self-rotation of the end plate body, the detector can achieve comprehensive coverage detection of the end plate. In this process, the detector can continuously acquire data and does not need to stay at each measurement point for a long time like traditional methods.

[0027] Among them, the device utilizes symmetrically distributed collection bins to simultaneously place multiple end plate bodies to be inspected; when the inspection of one end plate body is completed, the next end plate body can be quickly moved to the inspection position on the same horizontal plane through the rebound force of the reset spring, without the need to re-perform preparatory work such as positioning and installation of the end plate body as in the traditional inspection method, thereby realizing automatic replenishment of the end plate bodies to be inspected and avoiding time delays and operational errors caused by manual intervention; at the same time, this batch placement method can process more end plate bodies per unit time, reducing the equipment idle time during the inspection of a single end plate body, thereby improving the overall inspection efficiency.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] It should be noted that the above-mentioned detection main frame 1, controller 11, detector 12, drive assembly 13, end plate body 14 and other components can adopt commercially available related products. The structure and working principle of these products belong to the existing technology and will not be repeated here.

[0040] Example 1: Please refer to Figure 1 and Figure 2 As shown, the track-type end plate dimension runout detection device is used for performing comprehensive dimension detection and processing on the end plate body 14, including a detection main frame 1, a controller 11 is installed inside the detection main frame 1, a detector 12 is installed on the lower surface of the controller 11, a drive assembly 13 is symmetrically installed inside the detection main frame 1, an end surface detection mechanism 2 is arranged on the side wall of the drive assembly 13, and an auxiliary self-test mechanism 3 is arranged inside the detection main frame 1; the drive assembly 13 includes components such as belts, slide rails and moving cylinders.

[0041] Please refer to Figures 3 to 5 As shown, the end face detection mechanism 2 includes an auxiliary instrument 21 installed on the lower surface of the controller 11, a camera 22 is installed on the outer wall of the right track in the driving component 13, a display mainboard 23 is fixedly connected to the outer wall of the left track in the driving component 13, and a transparent lens 24 is slidably connected to the surface of the display mainboard 23.

[0042] It should be noted that the auxiliary instrument 21 and the detector 12 are both electrically controlled by the controller 11, the auxiliary instrument 21 and the detector 12 are located in the same vertical plane, the detector 12 corresponds to the eccentric position of the end plate body 14, the auxiliary instrument 21 and the end plate body 14 are in a separated and staggered state, the camera 22, the display main board 23 and the transparent lens 24 are all in the same horizontal plane, and the transparent lens 24 corresponds to the center position of the display main board 23 and the camera 22 respectively.

[0043] Specifically, Figure 2 As shown, at this time, the collection bins 37 on the surface of the main frame 1 are in a dispersed state. First, the staff moves the end plate body 14 to the designated area between the collection bins 37, then adjusts the position of the camera along the track in the drive assembly 13 to prepare for the subsequent precise size runout detection, and then collects the collection bins 37 to Figure 5 Finally, the staff starts the equipment to detect the end plate body 14.

[0044] During the detection process, the detection light emitted by the detector 12 is kept parallel to the auxiliary light emitted by the auxiliary instrument 21. When the detection light emitted by the subsequent detector 12 is irradiated to the surface of the end plate body 14, if the surface of the end plate body 14 is normal, compliant and flat, according to the principle of rectilinear propagation of light, the detection light will propagate in the original direction and always remain parallel to the auxiliary light. However, when abnormal conditions such as concave or convex surfaces appear on the surface of the end plate body 14, according to the principle of refraction of light, the propagation direction of the light will change. For example, if there is a convex surface on the surface of the end plate body 14, the detection light will be deflected in the normal direction. If the surface of the end plate body 14 is If there is a concave surface, the detection light will be deflected away from the normal direction. The light offset caused by this refraction will make the detection light and the auxiliary light no longer parallel, and this fluctuation will be mapped on the surface of the display mainboard 23 through the transparent lens 24, so as to be captured and photographed by the camera 22. By utilizing this intuitive visual presentation of whether the light overlaps or not, the flatness tolerance of the test is end-faceted to form an obvious fluctuation trajectory, and then the fluctuation difference can be intuitively detected by taking a picture with the camera 22, which greatly improves the intuitiveness of the detection. There is no need to rely on complex algorithms to interpret large amounts of data to determine whether there is a dimensional abnormality like traditional laser scanning.

[0045] It should be noted that the transparent lens 24 is a convex lens that is thick in the middle and thin at the edges. The side walls of the display mainboard 23 are evenly provided with wire grooves corresponding to the positions of the transparent lens 24. The center of the wire grooves remains parallel to the light at the output ends of the detector 12 and the auxiliary instrument 21.

[0046] Specifically, the wire groove set at the center position of the surface of the display main board 23 is initially parallel to the detection light and the auxiliary light, thereby providing an accurate reference position for detection. By subsequently observing whether the detection light is offset to the left or right side of the wire groove, it is possible to accurately determine whether the surface defect of the end plate body 14 is concave or convex, thereby avoiding subsequent unnecessary inspection and processing of the entire end plate body 14, thereby providing more targeted information for subsequent repair or quality improvement measures.

[0047] Example 2: Based on Example 1, please refer to Figures 6 to 9 As shown, the auxiliary self-test mechanism 3 includes a driving cylinder 31 inside the detection main frame 1, the output shaft end of the driving cylinder 31 is fixedly connected with a ring shaft 32, the outer wall of the ring shaft 32 is installed with a linkage shell 33, the outer wall of the linkage shell 33 is fixedly connected with a branch turntable 34, the upper surface of the branch turntable 34 is slidably connected with a bearing base 36, the interior of the bearing base 36 is installed with a reset spring 35, and the two sides of the bearing base 36 are symmetrically slidably connected with a folding bin 37.

[0048] It should be noted that the driving cylinder 31 maintains electrical connection with the controller 11, and the driving cylinder 31 is intermittently reciprocating and telescopically moved. The ring shaft 32 is located at the top of the output end of the driving cylinder 31, and the outer wall of the ring shaft 32 is evenly and fixedly connected with a cylindrical protrusion. A continuous bevel groove is opened on the inner wall of the linkage shell 33 at the position corresponding to the cylindrical protrusion, and the ring shaft 32 and the linkage shell 33 are rotationally connected through the cylindrical protrusion and the bevel groove.

[0049] Specifically, Figure 6 and Figure 7 As shown, when the whole device is started, inside the detection main frame 1, the driving cylinder 31 will synchronously start the working mode and can continuously perform telescopic movement, such as Figure 8 and Fig. 9 As shown, since the ring shaft 32 is closely connected to the output end of the driving cylinder 31, the ring shaft 32 will move up and down synchronously with the output end of the driving cylinder 31. During this process, the cylindrical protrusion on the outer wall of the ring shaft 32 will interact with the inclined groove on the inner wall of the ring shaft 32. Specifically, the cylindrical protrusion on the outer wall of the ring shaft 32 will continue to squeeze the inclined groove on the inner wall of the ring shaft 32. As the output shaft of the driving cylinder 31 completes a complete reciprocating movement in the up and down directions, this motion transmission will drive the linkage shell 33 to start working. The specific movement is as follows: since the output shaft of the driving cylinder 31 remains fixed in each extension and retraction process, the movement state of the ring shaft 32 also has a certain The regularity makes the subsequent linkage shell 33 rotate at a fixed amplitude each time when it is driven to rotate. Therefore, the linkage shell 33 will exhibit intermittent rotation under the drive of the ring shaft 32, and the amplitude of each rotation remains consistent. Through this fixed-amplitude rotation method, the tedious planning steps before detection are directly skipped, which greatly saves time and improves the overall efficiency of detection. For the irregularly shaped end plate body 14, the device does not rely on specific measurement point planning, and can more flexibly adapt to end plate bodies 14 of different shapes. Whether it is a round, square or other irregularly shaped end plate body 14, it can be fully detected through this rotation method, and there is no need to redesign the measurement point planning scheme for different shapes.

[0050] It should be noted that the two ends of the reset spring 35 are fixedly connected to the branch turntable 34 and the supporting base 36 respectively, the reset spring 35 initially maintains a compressed state, the folding bin 37 is composed of two incomplete circular shells, and the folding bins 37 are initially in a state of being away from each other.

[0051] Specifically, Figure 2 or Figure 5As shown, by utilizing the symmetrically distributed folding bins 37, multiple end plate bodies 14 to be inspected can be placed at the same time, and since multiple end plate bodies 14 are pre-placed in the folding bins 37, when the inspection of the top end plate body 14 is completed, the staff only needs to pull it out, and the subsequent uninspected end plate bodies 14 will automatically move upward to the inspection position quickly through the rebound force of the reset spring 35, without the need to re-position and install the end plate body 14 as in the traditional inspection method. The use of this rapid end plate body 14 switching mechanism helps to maintain the continuity of the inspection process and further improves the inspection efficiency. When the above-mentioned end plate body 14 moves upward, the reset spring 35 automatically drives the uninspected end plate body 14 below to rise to the same initial horizontal plane height, thereby avoiding time delays and operational errors caused by manual intervention and maintaining the consistency and continuity of the inspection process.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
