Description

Technical Field

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

[0002] The motorcycle frame is the core structure of a motorcycle, and its main uses include: 1. Support and connection: It bears components such as the engine, suspension system, and wheels, ensuring the correct installation and coordinated operation of each component; 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 during a collision and reduces injuries.

[0003] Therefore, the manufacturing quality of the motorcycle frame is very important. The existing detection of the shape and size tolerance of the motorcycle frame mostly relies on tooling customized for a certain type of frame, and manual measurement is carried out in cooperation with vernier calipers, micrometers, etc. Although the operation is simple, it has the disadvantages of low accuracy, poor work efficiency, and excessive dependence on the operator's 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 rotation frame assembly, the clamping and fixing assembly, and the safety buckle assembly, the rapid and safe clamping of the motorcycle frame can be realized. After the frame is clamped in place, the safety adjustment assembly and the flip-type scanning assembly are used in cooperation to complete the scanning detection work with high precision.

[0005] The purpose of the present invention is achieved through such a technical solution. A motorcycle frame detection device based on three-dimensional scanning includes a bottom frame member, a flip-type scanning assembly, a bottom rotation frame assembly, a clamping and fixing assembly, a safety adjustment assembly, and a safety buckle assembly. The flip-type scanning assembly includes a flip frame, the bottom rotation frame assembly includes a bottom fixing shaft and a top connecting plate, the clamping and fixing assembly includes a sliding column connecting plate, the safety adjustment assembly includes an adjustment driving gear, and the safety buckle assembly includes a first jack and a safety electric cylinder;

[0006] The end of the flip frame is rotatably connected to one side of the top of the bottom frame member, and a rotatable laser scanner is installed at the head end. The bottom fixing shaft is horizontally fixed to the other side of the top of the bottom frame member, the bottom end of the top connecting plate is rotatably connected to the bottom fixing shaft, a middle fixing gear is fixed in the middle of the bottom fixing shaft, and the slidable sliding column connecting plate is slidably connected to the top of the top connecting plate;

[0007] A sliding shaft that elastically moves upward is also slidably connected in the main body of the top connecting plate. The top end of the sliding shaft can contact and abut against the bottom surface of the sliding column connecting plate, and the rotatable adjustment driving 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 bottom frame member. The first jack is opened at the head end of the flipping frame. One end of the top connecting plate is provided with a second jack. When both the flipping frame and the top connecting plate are in the horizontal position, the telescopic rod of the safety electric cylinder can be inserted upward into the second jack and the first jack.

[0009] The usage process formed by the technical solution of the present invention is as follows:

[0010] When the flipping frame is in the horizontal position, the motorcycle frame to be detected can be clamped.

[0011] And before clamping, the sliding column connecting plate is in the upward moving and loosening position, which is convenient for placing the main shaft sleeve of the motorcycle frame between the top of the top connecting plate and the bottom surface of the sliding column connecting plate for clamping.

[0012] When the flipping frame is in the horizontal position, the top connecting plate is also in the horizontal position. At this time, by starting the safety electric cylinder to drive the upward movement of the telescopic rod of the safety electric cylinder, the telescopic rod of the safety electric cylinder can be inserted upward into the second jack and the first jack, so that both the top connecting plate and the flipping frame can be safely and stably maintained in the horizontal position.

[0013] And during the clamping process of the motorcycle frame, as the sliding column connecting plate moves downward, after the clamping of the motorcycle frame is completed and in place, the adjusting drive gear can just be engaged with the fixed middle fixed gear. After starting the drive mechanism connected to the adjusting drive gear, through the cooperative transmission formed by the adjusting drive gear and the middle fixed gear, the top connecting plate can be kept in the horizontal state.

[0014] Start the safety electric cylinder again, so that the telescopic rod of the safety electric cylinder moves downward and disengages from the first jack and the second jack. The flipping frame that can automatically rotate can drive the laser scanner to rotate to a certain height position to perform scanning and detection processing on the clamped motorcycle frame.

[0015] And the flipping frame can rotate within a certain range, and each group of laser scanners can also rotate within a certain range. In cooperation with the engagement of the adjusting drive gear and the middle fixed gear after the clamping of the motorcycle frame is completed and in place, it can also drive the top connecting plate and the motorcycle frame clamped between the sliding column connecting plate and the top connecting plate to rotate and adjust around the bottom fixed shaft.

[0016] Thus, not only can the viewing angles of the flipping frame and the laser scanner be adjusted, but also the three-dimensional scanning operation can be quickly realized 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 the turning frame to have a certain lateral length, so that after the turning frame is lifted, a certain height difference can be formed with the top end of the bottom frame member, enabling more accurate scanning and detection of the motorcycle frame clamped at the top end of the bottom frame member. Moreover, the turning frame itself can also automatically rotate to the horizontal position. In cooperation with the use of the safety electric cylinder, by utilizing the vertical movement of the telescopic rod of the safety electric cylinder, during the process of clamping the motorcycle frame, both the turning frame and the top connecting plate are in a safe horizontal position;

[0019] (2) And in the main body of the top connecting plate of the present invention, there is also a sliding shaft that elastically moves upward, and an adjustable driving gear capable of automatically rotating is installed at the bottom end of the sliding shaft. As the sliding column connecting plate moves up and down, not only can the clamping and loosening actions of the motorcycle frame be formed, but also after the motorcycle frame is clamped in place, the adjustable driving gear just meshes with the middle fixed gear. That is, after the motorcycle frame is clamped in place, the mechanism for keeping the top connecting plate in a horizontal state can be switched from the plug-in fit of the telescopic rod of the safety electric cylinder to the second jack to the meshing of the adjustable driving gear and the middle fixed gear. And after the telescopic rod of the safety electric cylinder moves down and exits the first jack and the second jack, the cooperative transmission formed by the adjustable driving gear and the middle fixed gear can not only keep the top connecting plate in a horizontal state, but also continuously rotate and adjust the top connecting plate relative to the bottom fixed shaft within a certain range, facilitating the self-rotation of the clamped motorcycle frame to form different positions relative to the cushion, improving the efficiency and accuracy of scanning and detection.

Apparently, the described embodiments are some, but not all, of the embodiments of the present invention.

[0036] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0037] As Figures 1 - 12 shown, a motorcycle frame detection device based on three-dimensional scanning, with the bottom frame member 1 as the support main body, the end of the flipping frame 201 is rotatably connected to one side of the top of the bottom frame member 1, and a rotatable laser scanner 208 is installed at the head end. The bottom fixing shaft 303 is horizontally fixedly connected to the other side of the top of the bottom frame member 1, the bottom end of the top connecting plate 306 is rotatably connected to the bottom fixing shaft 303, a middle fixing gear 307 is fixed in the middle of the bottom fixing shaft 303, and the slidable column connecting plate 406 that can move up and down is slidably connected to the top of the top connecting plate 306. The clamping of the main shaft sleeve of the motorcycle frame is realized between the top surface of the top connecting plate 306 and the bottom surface of the slidable column connecting plate 406;

[0038] A sliding shaft 602 that elastically moves upward is also slidably connected in the main body of the top connecting plate 306. The top end of the sliding shaft 602 can contact and abut against the bottom surface of the slidable column connecting plate 406. A rotatable adjusting drive gear 608 is installed at the bottom end of the sliding shaft 602, so that the adjusting drive gear 608 can move along with the slidable column connecting plate 406;

[0039] The safety electric cylinder 703 is installed and fixed in the frame on the other side of the bottom frame member 1. A first jack 702 is opened at the head end of the flipping frame 201, a second jack 705 is opened at one end of the top connecting plate 306, and when the flipping frame 201 and the top connecting plate 306 are both in the horizontal position, the telescopic rod of the safety electric cylinder 703 can be inserted upward into the second jack 705 and the first jack 702 to lock the horizontal states of the flipping frame 201 and the top connecting plate 306;

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

[0041] The flipping frame 201 has a certain lateral length, which is used to enable the laser scanner 208 to form a sufficient viewing range for the motorcycle frame to be scanned when the flipping frame 201 is lifted;

[0042] In the initial state, as Figure 11 shown, when the flipping 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 detected can be clamped;

[0043] And before clamping, the sliding column connecting plate 406 is in an upward moving and loosening position, which is convenient for placing the main shaft sleeve of the motorcycle frame 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 flipping frame 201 is in a horizontal position, the top connecting plate 306 is also in a horizontal position. At this time, by starting the safety electric cylinder 703 and driving the upward movement of the telescopic rod of the safety electric cylinder 703, the telescopic rod of the safety electric cylinder 703 can be inserted upward into the second jack 705 and the first jack 702, so that both the top connecting plate 306 and the flipping frame 201 can be safely and stably maintained in a horizontal position;

[0045] And the clamping fit formed by the telescopic rod of the safety electric cylinder 703 on the horizontal position of the top connecting plate 306 is sufficient to support the clamping of the motorcycle workshop;

[0046] And during the clamping process of the motorcycle frame, as the sliding column connecting plate 406 moves downward, after the clamping of the motorcycle frame is completed and in place, the adjusting drive gear 608 just can engage with the fixed middle fixed gear 307. After starting the drive mechanism connected to the adjusting drive gear 608, through the cooperative transmission formed by the adjusting drive gear 608 and the middle fixed gear 307, the top connecting plate 306 can be kept in a horizontal state;

[0047] Start the safety electric cylinder 703 again, so that the telescopic rod of the safety electric cylinder 703 moves downward and disengages from the first jack 702 and the second jack 705. Through the rotatable flipping frame 201, the laser scanner 208 can be driven to rotate to a certain height position to scan and detect the clamped motorcycle frame, and the three-dimensional data formed by the scan can be compared with the design data to realize the detection of the shape tolerance of the motorcycle frame;

[0048] And the flipping frame 201 can rotate within a certain range, and each group of laser scanners 208 can also rotate within a certain range. In cooperation with the engagement formed by the adjusting drive gear 608 and the middle fixed gear 307 after the clamping of the motorcycle frame is completed and in place, it 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 and adjust around the bottom fixed shaft 303;

[0049] Since the bottom fixing shaft 303 and the flipping frame 201 are in a spatially perpendicular state, not only can the viewing angle of the flipping frame 201 and the laser scanner 208 be adjusted, but also the three-dimensional scanning operation can be quickly realized through the adjustment of the motorcycle frame itself after clamping;

[0050] After the scanning work is completed, both the flipping frame 201 and the top connecting plate 306 are restored to the horizontal position again, and the safety electric cylinder 703 is started again to lock the water level positions of the flipping frame 201 and the top connecting plate 306, which can not only facilitate the safe removal of the inspected motorcycle frame, but also quickly clamp a new motorcycle frame to be clamped.

[0051] The specific structures of the bottom frame member 1 and the flipping type scanning assembly 2 are as Figure 2 and Figure 3 shown, including a bottom frame body 101 and a rotating frame hole position 102. The rotating frame hole position 102 is opened on the other side of the top end of the bottom frame body 101 to provide space for the rotation adjustment of the top connecting plate 306 and its related components;

[0052] On one side of the top end of the bottom frame body 101, flipping seats 202 are symmetrically fixed. On both sides of the end of the flipping frame 201, transverse rotating shafts 203 are fixedly arranged. The rotating shafts 203 on the same side are rotatably connected to the flipping seats 202;

[0053] The flipping motor 204 is installed and fixed on the inner bottom surface of the top end of the bottom frame body 101. The driving toothed belt pulley 205 is inserted and fixed in the rotating shaft of the flipping motor 204. On the outer shaft end of one group of rotating shafts 203, a flipping toothed belt pulley 206 is inserted and fixed. A toothed belt 207 is sleeved and installed between the driving toothed belt pulley 205 and the flipping toothed belt pulley 206;

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

[0055] On the head end of the flipping frame 201, steering seats 209 are fixedly installed in pairs. The steering motor 210 is installed and fixed on one side of the head end of the flipping frame 201, and the rotating shaft of the steering motor 210 is rotatably 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, forming the rotation adjustment of the laser scanner 208 itself relative to the steering seat 209.

[0056] The specific structure of the bottom rotating frame assembly 3 is as 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 the vertical seats 302 are fixed in pairs at the top middle part of the bottom horizontal plate 301, and the bottom fixed shaft 303 is laterally plugged and fixed at 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, and the rotating arms 305 are rotatably connected to the bottom fixed shaft 303;

[0058] When the adjustment driving 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 composed 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 column 401 and the slide cylinder 402 are respectively fixed on both sides of the top of the top connecting plate 306, the inner slide column 403 is slidably inserted into the slide cylinder 402, the slide column connecting plate 406 is fixedly connected to the top of the inner slide column 403, and the upper end side wall of the slide cylinder 402 is provided with a vertical groove 404, and the outer surface of the inner slide column 403 is fixedly connected with a vertical slide seat 405, and the vertical slide seat 405 is slidably connected with the vertical groove 404;

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

[0061] A top plug post 407 is fixed on the other side of the bottom surface of the sliding column connecting plate 406 and is directly opposite to the bottom plug post 401. A clamping pad 408 is sleeved and fixed at the position where the bottom plug post 401 is connected to the top of the top connecting plate 306 and the position where the top plug post 407 is connected to 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 for flexible clamping of 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 bottom rotating seat 414 of the screw 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 top rotating seat 412 of the screw. The bottom end of the clamping screw 410 is rotationally connected to the bottom rotating seat 414, and the upper end is rotationally connected to the top rotating seat 412 of the screw. A screw slider 411 is fixedly installed in the inner hole jointly opened by the slide column connecting plate 406 and the inner slide column 403, and the screw slider 411 is matched and connected in 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 column 403 and the slide cylinder 402 form a sliding insertion, and the vertical slide seat 405 and the vertical groove 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 matching transmission, which can drive the slide column 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 insertion column 401, the slide column connecting plate 406 moves downward, driving the top insertion column 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 fixedly mounted on the outer side surface of the slide column connecting plate 406 and is coaxial with the inner slide column 403 and the clamping screw 410. The top inner bottom surface of the side connecting seat 409 is fixedly mounted with a yielding motor 503. A yielding driving 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 driving gear 504 and can also be disengaged from the yielding driving 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 seat 405 before it escapes from the vertical groove 404, and the passive half gear 502 has moved to the position of meshing with the yielding drive gear 504. As the inner slide 403 and the slide cylinder 402 escape, the vertical slide seat 405 and the vertical groove 404 escape, and the passive half gear 502 and the yielding drive gear 504 are meshed in place;

[0067] With the clamping lead screw 410 in a non-rotating state, the retracting motor 503 is started to drive the cooperative transmission formed by the retracting drive gear 504 and the passive half gear 502, 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 lead screw slider 411 in cooperation with the clamping lead screw 410, when the component composed of the inner sliding column 403 and the sliding column connecting plate 406 moves upward, it can synchronously rotate to a position where the top inserting column 407 and the bottom inserting column 401 are not aligned. The purpose is to move the sliding column connecting plate 406 and the top inserting column 407 above the bottom inserting column 401 to avoid interfering with the insertion of the bottom end of the motorcycle frame into the bottom inserting column 401. After the bottom end of the motorcycle frame is inserted into the bottom inserting column 401 in place, the sliding column connecting plate 406 is rotated back again, so that the top inserting column 407 maintains a state of being precisely coaxially aligned with the bottom inserting column 401. At this time, the retracting drive gear 504 is in a stable stop state, and through the meshing formed by the passive half gear 502 and the retracting drive gear 504, a state where the sliding column connecting plate 406 rotates freely will not be formed.

[0068] And in order to achieve the rotation accuracy of the sliding column connecting plate 406, that is, when the component composed of the inner sliding column 403 and the sliding column connecting plate 406 can rotate back to a position where the vertical sliding seat 405 is exactly aligned with the vertical groove 404 after the bottom end of the motorcycle frame is inserted into the bottom inserting column 401 in place, the retracting motor 503 must be a servo motor, which can precisely 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 retracting drive gear 504 and the passive half gear 502.

[0069] With the start of the lead screw motor 413 driving the rotation of the clamping lead screw 410, the clamping lead screw 410 drives the inner sliding column 403 to insert into the sliding cylinder 402 and the vertical sliding seat 405 to insert into the vertical groove 404 through the transmission in cooperation with the lead screw slider 411. And when the vertical sliding seat 405 is not completely inserted into the vertical groove 404, the passive half gear 502 is in a position completely disengaged from the retracting drive gear 504. After the vertical sliding seat 405 is completely immersed in the vertical groove 404, the passive half gear 502 disengages from the retracting drive gear 504. As the inner sliding column 403 and the sliding column connecting plate 406 continue to move downward, the clamping work on the main shaft sleeve of the motorcycle frame can be completed.

[0070] A limiting seat 501 is also fixedly installed on the inner bottom surface of the top end of the side connecting seat 409. The limiting seat 501 is made of nylon and has a round hole in the middle that does not interfere with the rotation of the clamping lead screw 410, which is used for hard limiting the upward movement position of the sliding column connecting plate 406 to protect the cooperation formed by the passive half gear 502 and the retracting drive gear 504.

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

[0072] Under the action of the self-supporting elastic force of the compression spring 605, it can make the sliding column connecting plate 406 contact and abut against the sliding shaft top plate 603 within a certain stroke range of the sliding column connecting plate 406. When the sliding column connecting plate 406 moves upward to the upper limit where the top insertion column 407 is located, which is convenient for the clamping position of the motorcycle frame main shaft sleeve, 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 in 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 sliding cylinder 402;
