Description

Technical Field

[0001] The present invention relates to the technical field of motorcycle parts inspection, and in particular to a motorcycle frame inspection device based on three-dimensional scanning. Background Art

[0002] The motorcycle frame is the core structure of the motorcycle, and its main uses include: 1. Support and connection: it carries the engine, suspension system, wheels and other components, ensuring that all components are correctly installed and work together; 2. Strength and rigidity: it provides sufficient strength and rigidity to ensure driving stability and safety; 3. Shock absorption and comfort: it absorbs road vibrations through design to improve riding comfort; 4. Safety: it protects the rider in the event of a collision and reduces injuries.

[0003] Therefore, the manufacturing quality of motorcycle frames is very important. Existing motorcycle frame dimensional tolerance inspection mostly relies on customized tooling for a specific frame and manual measurement with vernier calipers, micrometers, etc. Although the operation is simple, it has disadvantages such as low precision, poor work efficiency, and excessive dependence on operator skills. Summary of the Invention

[0004] The purpose of the present invention is to provide a motorcycle frame detection device based on three-dimensional scanning. Through the cooperation of the bottom rotating frame assembly, the clamping and fixing assembly and the safety buckle assembly, the motorcycle frame can be quickly and safely clamped. After the frame is clamped in place, the safety adjustment assembly is used in conjunction with the flip-type scanning assembly to complete the scanning and detection work with high precision.

[0005] The objective of the present invention is achieved through such a technical solution, a motorcycle frame detection device based on three-dimensional scanning, comprising a chassis component, a flip scanning assembly, a bottom rotating frame assembly, a clamping and fixing assembly, a safety adjustment assembly and a safety buckle assembly, wherein the flip scanning assembly comprises a flip frame, the bottom rotating frame assembly comprises a bottom fixed shaft and a top connecting plate, the clamping and fixing assembly comprises a sliding column connecting plate, the safety adjustment assembly comprises an adjustment drive gear, and the safety buckle assembly comprises a first socket and a safety electric cylinder;

[0006] The end of the flip frame is screwed to one side of the top of the chassis member, and a rotatable laser scanner is installed at the head end. The bottom fixed shaft is transversely fixed to the other side of the top of the chassis member. The bottom end of the top connecting plate is screwed to the bottom fixed shaft. A middle fixed gear is fixed to the middle of the bottom fixed shaft. A sliding column connecting plate that can be lifted and moved is slidably connected to the top of the top connecting plate.

[0007] The main body of the top connecting plate is also provided with a sliding shaft that is elastically connected upwards. The top end of the sliding shaft can contact and abut against the bottom surface of the sliding column connecting plate. A rotatable adjustment drive gear is installed at the bottom end of the sliding shaft.

[0008] The safety electric cylinder is installed and fixed in the frame on the other side of the base frame member. The first socket is opened at the head end of the flip frame, and the second socket is opened at one end of the top connecting plate. When the flip frame and the top connecting plate are both in a horizontal position, the telescopic rod of the safety electric cylinder can be inserted upward into the second socket and the first socket.

[0009] The use process of the technical solution of the present invention is as follows:

[0010] When the flip frame is in a horizontal position, the motorcycle frame to be tested can be clamped;

[0011] Before clamping, the sliding column connecting plate is in an upwardly moved and loosened position, so that the main shaft sleeve of the motorcycle frame can be placed between the top of the top connecting plate and the bottom surface of the sliding column connecting plate for clamping;

[0012] When the turning frame is in a horizontal position, the top connecting plate is also in a horizontal position. At this time, by starting the safety electric cylinder, the telescopic rod of the safety electric cylinder is driven to move upward, so that the telescopic rod of the safety electric cylinder can be inserted upward into the second hole and the first hole, so that the top connecting plate and the turning frame can be safely and stably maintained in a horizontal position;

[0013] During the clamping process of the motorcycle frame, as the sliding column connecting plate moves downward, after the motorcycle frame is clamped and in place, the adjusting drive gear can just mesh with the fixed middle gear. After the driving mechanism connected to the adjusting drive gear is started, the top connecting plate can be kept in a horizontal state through the coordinated transmission formed by the adjusting drive gear and the middle gear.

[0014] The safety electric cylinder is started again, so that the telescopic rod of the safety electric cylinder moves downward and disengages from the first and second sockets. The automatically rotatable flip frame can drive the laser scanner to rotate to a certain height position to scan and detect the clamped motorcycle frame.

[0015] The flip frame can rotate within a certain range, and each set of laser scanners can also rotate within a certain range. After the motorcycle frame is clamped in place, the meshing between the drive gear and the middle fixed gear is adjusted, and the top connecting plate and the motorcycle frame clamped between the sliding column connecting plate and the top connecting plate can be rotated and adjusted around the bottom fixed axis.

[0016] This not only allows the viewing angles of the flip frame and the laser scanner to be adjusted, but also allows for rapid three-dimensional scanning operations by adjusting the motorcycle frame itself after clamping.

[0017] By adopting the above technical solution, the present invention can achieve the following beneficial effects:

[0018] (1) The present invention sets a certain horizontal length for the turning frame, so that after the turning frame is rotated, a certain height difference can be formed with the top of the chassis member, so that the motorcycle frame clamped on the top of the chassis member can be scanned and detected more accurately, and the turning frame itself can also automatically rotate to a horizontal position. In conjunction with the use of a safety electric cylinder, the vertical movement of the telescopic rod of the safety electric cylinder can ensure that the turning frame and the top connecting plate are in a safe horizontal position during the process of clamping the motorcycle frame;

[0019] (2) The present invention also has an elastic upward sliding shaft in the main body of the top connecting plate, and an automatically rotating adjusting drive gear is installed at the bottom end of the sliding shaft, so that as the sliding column connecting plate moves up and down, it can not only form a clamping and loosening action on the motorcycle frame, but also make the adjusting drive gear just mesh with the middle solid gear after the motorcycle frame is clamped in place, that is, after the motorcycle frame is clamped in place, the mechanism for keeping the top connecting plate in a horizontal state can be converted from the plug-in cooperation of the telescopic rod of the safety electric cylinder to the second socket to the meshing of the adjusting drive gear and the middle solid gear, and after the telescopic rod of the safety electric cylinder moves down and exits the first socket and the second socket, the cooperative transmission formed by the adjusting drive gear and the middle solid gear can not only keep the top connecting plate in a horizontal state, but also continuously adjust the rotation of the top connecting plate relative to the bottom solid shaft within a certain range, so as to facilitate the rotation of the clamped motorcycle frame itself to form different positions relative to the card pad, thereby improving the efficiency and accuracy of scanning detection.

DETAILED DESCRIPTION

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of 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. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0036] In the description of the present invention, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] like Figures 1-12 As shown, a motorcycle frame detection device based on three-dimensional scanning is shown, wherein the chassis member 1 serves as the supporting body, the end of the flip frame 201 is screwed to one side of the top of the chassis member 1, and a rotatable laser scanner 208 is installed at the head end. The bottom fixed shaft 303 is laterally fixed to the other side of the top of the chassis member 1, the bottom end of the top connecting plate 306 is screwed to the bottom fixed shaft 303, and a middle fixed gear 307 is fixed to the middle of the bottom fixed shaft 303. A sliding column connecting plate 406 that can be lifted and moved is slidably connected to the top of the top connecting plate 306, and the top surface of the top connecting plate 306 and the bottom surface of the sliding column connecting plate 406 are used to realize the clamping of the main shaft sleeve of the motorcycle frame;

[0038] The main body of the top connecting plate 306 is also provided with a sliding shaft 602 that is elastically movable upward. The top end of the sliding shaft 602 is capable of contacting and abutting against the bottom surface of the sliding column connecting plate 406. A rotatable adjustment drive gear 608 is mounted on the bottom end of the sliding shaft 602, allowing the adjustment drive gear 608 to move along with the sliding column connecting plate 406.

[0039] The safety electric cylinder 703 is fixed to the frame on the other side of the chassis member 1. The first socket 702 is provided at the head end of the flip frame 201. A second socket 705 is provided at one end of the top connecting plate 306. When the flip frame 201 and the top connecting plate 306 are both in a horizontal position, the telescopic rod of the safety electric cylinder 703 can be inserted upward into the second socket 705 and the first socket 702, thereby locking the flip frame 201 and the top connecting plate 306 in a horizontal state.

[0040] The working principle of the device is as follows:

[0041] The flip frame 201 has a certain transverse length so that when the flip frame 201 is raised, the laser scanner 208 can form a sufficient viewing angle range for the motorcycle frame to be scanned;

[0042] In the initial state, if Figure 11 As shown, when the flip frame 201 is in a horizontal position, that is, in a position that does not interfere with the clamping of the motorcycle frame, the motorcycle frame to be tested can be clamped;

[0043] Before clamping, the sliding column connecting plate 406 is in an upwardly moved and loosened position, so that the main shaft sleeve of the motorcycle frame can be placed between the top of the top connecting plate 306 and the bottom surface of the sliding column connecting plate 406 for clamping;

[0044] When the turning frame 201 is in a horizontal position, the top connecting plate 306 is also in a horizontal position. At this time, by activating the safety electric cylinder 703, the telescopic rod of the safety electric cylinder 703 moves upward, so that the telescopic rod of the safety electric cylinder 703 is inserted upward into the second insertion hole 705 and the first insertion hole 702, so that the top connecting plate 306 and the turning frame 201 can be safely and stably maintained in a horizontal position.

[0045] Furthermore, the horizontal snap-fitting of the top connecting plate 306 formed by the telescopic rod of the safety electric cylinder 703 is sufficient to support the clamping in the motorcycle workshop;

[0046] During the clamping process of the motorcycle frame, as the sliding column connecting plate 406 moves downward, after the motorcycle frame is clamped and in place, the adjusting drive gear 608 can just mesh with the fixed middle gear 307. After the driving mechanism connected to the adjusting drive gear 608 is started, the top connecting plate 306 can be kept in a horizontal state through the coordinated transmission formed by the adjusting drive gear 608 and the middle gear 307.

[0047] The safety electric cylinder 703 is activated again, causing the telescopic rod of the safety electric cylinder 703 to move downward and disengage from the first socket 702 and the second socket 705. The automatically rotatable flip frame 201 can drive the laser scanner 208 to rotate to a certain height position, and the clamped motorcycle frame can be scanned and inspected. The three-dimensional data generated by the scan can be compared with the design data to realize the shape tolerance inspection of the motorcycle frame.

[0048] The tilting frame 201 can rotate within a certain range, and each set of laser scanners 208 can also rotate within a certain range. After the motorcycle frame is clamped in place, the meshing formed by adjusting the driving gear 608 and the middle fixed gear 307 can also drive the top connecting plate 306 and the motorcycle frame clamped between the sliding column connecting plate 406 and the top connecting plate 306 to rotate around the bottom fixed shaft 303.

[0049] Since the bottom fixed shaft 303 and the turning frame 201 are in a vertical position in space, not only can the viewing angle of the turning frame 201 and the laser scanner 208 be adjusted, but also the three-dimensional scanning operation can be quickly achieved by adjusting the motorcycle frame itself after the clamping is completed;

[0050] After the scanning work is completed, the flip frame 201 and the top connecting plate 306 are restored to the horizontal position, and the safety electric cylinder 703 is started again to lock the water level position of the flip frame 201 and the top connecting plate 306, which can facilitate the safe removal of the motorcycle frame after the inspection and quickly clamp the new motorcycle frame to be clamped.

[0051] The specific structure of the chassis component 1 and the flip scanning component 2 is as follows Figure 2 and Figure 3 As shown, it includes a base frame 101 and a rotating frame hole 102. The rotating frame hole 102 is opened on the other side of the top of the base frame 101 to provide space for the rotation adjustment of the top connecting plate 306 and its related components;

[0052] A flip seat 202 is symmetrically fixed to one side of the top of the bottom frame 101. A flip shaft 203 is fixed horizontally on both sides of the end of the flip frame 201. The flip shaft 203 on the same side is rotatably connected to the flip seat 202.

[0053] The flip motor 204 is mounted and fixed on the inner bottom surface of the top of the bottom frame 101, and the driving toothed belt pulley 205 is inserted and fixed in the rotating shaft of the flip motor 204. The outer shaft end of one set of flip shafts 203 is inserted and fixed with a flip toothed belt pulley 206, and a toothed belt 207 is installed between the driving toothed belt pulley 205 and the flip toothed belt pulley 206.

[0054] The turning motor 204 is started to drive the driving toothed belt pulley 205 to rotate, so that the driving toothed belt pulley 205 drives the turning toothed belt pulley 206 to rotate via the toothed belt 207, thereby driving the turning frame 201 to rotate relative to the turning seat 202. The turning frame 201 can be rotated to a horizontal position and the rotation angle of the turning frame 201 relative to the turning frame hole 102 can be adjusted within a certain range.

[0055] The head end of the flip frame 201 is fixedly installed with a pair of steering seats 209, the steering motor 210 is installed and fixed on one side of the head end of the flip frame 201, and the rotating shaft of the steering motor 210 is rotationally connected to the steering seat 209. The main body of the laser scanner 208 is fixed to the outer end face of the steering motor 210, so that the laser scanner 208 itself can be rotated and adjusted relative to the steering seat 209.

[0056] The specific structure of the bottom rotating frame assembly 3 is as follows Figure 4As shown, a bottom horizontal plate 301 is fixedly connected between the inner frames at the bottom end of the bottom frame body 101, and a pair of vertical seats 302 are fixed to the top middle portion of the bottom horizontal plate 301, and a bottom fixed shaft 303 is laterally plugged and fixed to the top of the vertical seats 302;

[0057] The bottom middle part of the bottom rotating frame 304 is fixed with rotating arms 305 on both outer sides. The top connecting plate 306 is fixedly connected to the top of the bottom rotating frame 304. The rotating arms 305 are rotatably connected to the bottom fixed shaft 303.

[0058] When the adjustment drive gear 608 is not engaged with the middle fixed gear 307 and the horizontal position of the top connecting plate 306 is not limited by the safety electric cylinder 703, the component consisting of the top connecting plate 306 and the bottom rotating frame 304 can rotate freely around the bottom fixed shaft 303.

[0059] The specific structures of the clamping and fixing component 4, the clamping and giving way component 5 and the safety adjustment component 6 are as follows: Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown, the bottom plug post 401 and the slide 402 are respectively fixed to the two sides of the top of the top connecting plate 306, the inner slide post 403 is slidably inserted into the interior of the slide 402, the slide post connecting plate 406 is fixedly connected to the top of the inner slide post 403, and a vertical groove 404 is formed on the upper side wall of the slide 402. The outer surface of the inner slide post 403 is fixedly connected to a vertical slide seat 405, and the vertical slide seat 405 is slidably connected to the vertical groove 404;

[0060] The inner slide column 403 can move vertically in the slide cylinder 402 when the inner slide column 403 is slidably inserted into the slide cylinder 402 and the vertical slide seat 405 is slidably connected to the vertical groove 404.

[0061] A top plug post 407 is fixed on the other side of the bottom surface of the sliding column connecting plate 406, which is opposite to the bottom plug post 401. A clamping pad 408 is fixed at the position where the bottom plug post 401 meets the top of the top connecting plate 306 and the position where the top plug post 407 meets the bottom surface of the sliding column connecting plate 406. The clamping pad 408 is made of rubber with a certain hardness and is used to flexibly clamp the two ends of the main shaft sleeve of the motorcycle frame.

[0062] The bottom end of the side connecting seat 409 is sleeved on the outer surface of the slide 402, the screw bottom rotating seat 414 is fixedly connected to the bottom end of the side connecting seat 409, and passes through the vertical slot 404 and is located inside the slide 402. The top of the side connecting seat 409 is fixedly installed with a screw top rotating seat 412. The bottom end of the clamping screw 410 is rotationally connected to the screw bottom rotating seat 414, and the upper end is rotationally connected to the screw top rotating seat 412. A screw slider 411 is fixedly installed in the inner hole jointly defined by the slide column connecting plate 406 and the inner slide column 403, and the screw slider 411 is cooperatively connected to the clamping screw 410;

[0063] A lead screw motor 413 is fixedly mounted on the outer top end of the side connecting seat 409, and the top shaft end of the clamping lead screw 410 is fixedly connected to the rotating shaft of the lead screw motor 413;

[0064] Within the range where the inner slide post 403 and the slide cylinder 402 form a sliding insertion, and the vertical slide seat 405 and the vertical slot 404 form a sliding connection, the screw motor 413 is started to drive the rotation of the clamping screw 410, so that the clamping screw 410 and the screw slider 411 form a coordinated transmission, which can drive the slide post connecting plate 406 to automatically move up and down, so that after the bottom end of the motorcycle frame main shaft sleeve is inserted into the bottom insert post 401, the downward movement of the slide post connecting plate 406 drives the top insert post 407 to be inserted into the top end of the motorcycle frame main shaft sleeve, and the motorcycle frame main shaft sleeve is clamped by the clamping pads 408 on both sides;

[0065] The passive half gear 502 is fixed to the outer side surface of the sliding column connecting plate 406 and is coaxial with the inner sliding column 403 and the clamping screw 410. The yielding motor 503 is fixedly mounted on the inner bottom surface of the top of the side connecting seat 409. The yielding drive gear 504 is inserted and fixed in the rotating shaft of the yielding motor 503. The passive half gear 502 can mesh with the yielding drive gear 504 and can also be disengaged from the yielding drive gear 504.

[0066] Through the coordinated transmission formed by the clamping screw 410 and the screw slider 411, the inner slide 403 is driven to move upward to the vertical slide 405 without being disengaged from the vertical groove 404. The passive half gear 502 has already moved to a position where it meshes with the yielding drive gear 504. As the inner slide 403 and the slide cylinder 402 are disengaged, the vertical slide 405 and the vertical groove 404 are disengaged, and the passive half gear 502 is meshed with the yielding drive gear 504.

[0067] When the clamping screw 410 is in a non-rotating state, the yielding motor 503 is started to drive the yielding driving gear 504 and the passive half gear 502 to form a transmission, which can form a component composed of the inner sliding column 403 and the sliding column connecting plate 406. Relative to the rotation of the screw slider 411 and the clamping screw 410, the component composed of the inner sliding column 403 and the sliding column connecting plate 406 can be synchronously rotated to a position where the top plug column 407 and the bottom plug column 401 are not aligned while moving upward, so as to move the sliding column connecting plate 407 upward. 6 and the top plug-in post 407 are moved to the top of the bottom plug-in post 401 without interfering with the insertion of the bottom end of the motorcycle frame and the bottom plug-in post 401; after the bottom end of the motorcycle frame is inserted into the bottom plug-in post 401, the sliding post connecting plate 406 is re-rotated so that the top plug-in post 407 remains in a state of precise coaxial alignment with the bottom plug-in post 401. At this time, the yield drive gear 504 is in a stable stopped state. The engagement formed by the passive half gear 502 and the yield drive gear 504 prevents the sliding post connecting plate 406 from rotating freely.

[0068] In order to achieve the precision of the rotation of the sliding column connecting plate 406, that is, to ensure that the component composed of the inner sliding column 403 and the sliding column connecting plate 406 can be inserted into the bottom plug column 401 at the bottom end of the motorcycle frame and the vertical slide 405 can return to the position directly opposite the vertical groove 404, the yielding motor 503 must be a servo motor that can accurately control the rotation angle of the component composed of the inner sliding column 403 and the sliding column connecting plate 406 formed by the cooperation of the yielding driving gear 504 and the driven half gear 502;

[0069] As the screw motor 413 is started to drive the clamping screw 410 to rotate, the clamping screw 410 can drive the inner slide 403 to be inserted into the slide cylinder 402 through the transmission coordinated with the screw slider 411, and the vertical slide 405 is inserted into the vertical groove 404. When the vertical slide 405 is not completely inserted into the vertical groove 404, the passive half gear 502 is in a position where the yielding drive gear 504 is completely disengaged. After the vertical slide 405 is completely immersed in the vertical groove 404, the passive half gear 502 is disengaged from the yielding drive gear 504. As the inner slide 403 and the slide connecting plate 406 continue to move downward, the clamping work of the motorcycle frame main shaft sleeve can be completed.

[0070] A fixed limit seat 501 is also installed on the inner bottom surface of the top of the side connecting seat 409. The limit seat 501 is made of nylon and has a circular hole in the middle that does not interfere with the rotation of the clamping screw 410. It is used to hard limit the upward position of the sliding column connecting plate 406 and protect the cooperation formed by the passive half gear 502 and the yielding drive gear 504;

[0071] A fixed sliding seat 601 is installed in the main body of the top connecting plate 306. The sliding shaft 602 is slidably connected to the fixed sliding seat 601. The sliding shaft top plate 603 is fixedly connected to the top of the sliding shaft 602 and contacts and abuts against the bottom surface of the sliding column connecting plate 406. The middle connecting plate 604 is sleeved and fixed to the outside of the middle part of the sliding shaft 602. The compression spring 605 is sleeved and installed on the outside of the sliding shaft 602, and the top end is clamped to the middle connecting plate 604 and the bottom end is clamped to the top connecting plate 306.

[0072] Under the action of the supporting elastic force of the compression spring 605, the sliding column connecting plate 406 can be in contact with the sliding shaft top plate 603 within a certain range of travel. When the sliding column connecting plate 406 moves upward to the upper limit of the top plug-in column 407, which is convenient for the clamping position of the main shaft sleeve of the motorcycle frame, the bottom surface of the sliding column connecting plate 406 has been separated from the sliding shaft top plate 603. That is, when the sliding column connecting plate 406 is at the upper limit position, the sliding shaft top plate 603 will not interfere with the rotation of the sliding column connecting plate 406 after the inner sliding column 403 is separated from the slide cylinder 402.

[0073] A sliding shaft base plate 606 is fixed to the bottom end of the sliding shaft 602, an adjustment motor 607 is mounted and fixed on the bottom surface of the sliding shaft base plate 606, and an adjustment drive gear 608 is inserted and fixed in the rotating shaft of the adjustment motor 607, which can drive the adjustment drive gear 608 to rotate automatically;

[0074] The space formed between the bottom end of the top connecting plate 306 and the middle solid gear 307 is sufficient to support the movement of the adjustment motor 607 and the adjustment driving gear 608.
