Description

Technical Field

[0001] The present invention relates to the technical field of motorcycle manufacturing, and particularly relates to a dynamic balance detection device for motorcycle wheels based on three-dimensional scanning. Background Art

[0002] The main purpose of dynamic balance detection of motorcycle wheels is to ensure that the wheels can maintain balance during high-speed rotation, avoiding vibration and instability; its specific objectives include: improving driving comfort, reducing vibration caused by imbalance, and enhancing riding comfort; enhancing safety, preventing handling difficulties caused by vibration, and reducing the risk of accidents; extending the service life of components, reducing wear on components such as the suspension system and bearings caused by imbalance, and extending the service life; optimizing performance, ensuring uniform wear of the tires, and enhancing the overall performance of the vehicle.

[0003] Currently, dynamic balance detection of motorcycle wheels is mostly manually operated. By installing the wheel hub on a balance bracket, manually rotating the wheel hub, and using a dial indicator to detect the outer surface of the wheel hub, although the operation is simple, the detection accuracy is very limited. Some existing dynamic balance detection devices can simulate the high-speed rotation of the wheel and automatically measure the amount and position of imbalance of the contour. Although the detection accuracy is higher than manual detection, the operation is complex and requires professional technicians to complete. Summary of the Invention

[0004] The purpose of the present invention is to provide a dynamic balance detection device for motorcycle wheels based on three-dimensional scanning. Taking the arched fixing frame fixed at the top of the conveying module as a reference, cooperating with the use of the transfer component, the rotating arm component, and the clamping component, and using the relative reverse transmission method formed by the trapezoidal column and the end fixing seat, the laser scanner can be realized to perform detection work at multiple workstations, and more accurately and efficiently realize the automatic detection of the dynamic balance of motorcycle wheels.

[0005] The purpose of the present invention is achieved through such a technical solution. A dynamic balance detection device for motorcycle wheels based on three-dimensional scanning includes a transfer component, a conveying module, a detection drive module, a rotating arm component, a clamping component, a three-dimensional scanning module, and a side insertion member. The transfer component includes a laser displacement sensor, the detection drive module includes a driving gear, the rotating arm component includes a side rotating arm, the clamping component includes an inner inserted rotating shaft, the three-dimensional scanning module includes an arched insertion frame and a laser scanner, and the side insertion member includes a trapezoidal column;

[0006] The upper end of the transfer component is symmetrically slidably connected with an outer connecting plate that can move synchronously. The laser displacement sensor is installed in the middle of one side of the top of the transfer component;

[0007] The bottom end of the side rotary arm is screwed to the outside of the external connection plate, and the automatically rotatable driving gear is symmetrically screwed to the top of the transfer assembly. The inner side of the top of each set of side rotary arms is connected to an end fixed seat that can automatically move laterally, and the inner inserted rotary shaft is screwed to the end fixed seat. Each set of inner inserted rotary shafts is inserted with an external pressure sleeve and a passive gear.

[0008] An arched fixed frame is fixedly connected to one side of the upper end of the conveying module, the arched plug-in frame is magnetically plugged into the arched fixed frame, the laser scanner is slidably connected to the arched plug-in frame, and side fixed arms are fixed to both sides of the bottom end of the arched plug-in frame. A trapezoidal plug hole is provided at one end of each set of side fixed arms close to the transfer assembly, the trapezoidal column is slidably connected to the side rotary arm, and the trapezoidal column on the same side is reversely driven and connected to the end fixed seat;

[0009] The top of the transfer assembly is symmetrically fixed with safety seats, and each group of safety seats is elastically slidably connected with a safety slide column inwardly.

[0010] The use process of the technical solution of the present invention is as follows:

[0011] In the undetected state, the arched bracket is magnetically connected to the arched fixed bracket fixed on the upper end of the conveying module. At this time, the laser scanner slidably connected to the arched bracket is in a position to detect the wheel hub conveyed in the conveying module. The laser scanner can be used to scan and confirm the coordinate position of the center hole of a group of wheel hubs conveyed to the position close to the transfer component, which is used to feed back to the external control system, automatically control the lateral movement of the external connecting plate, and the automatic rotation of the side rotary arm, drive the inner insert rotary shaft to move to the position opposite to the center hole of the wheel hub, and in this process, the symmetrically distributed end fixed seats are in the extreme position of outward movement, and the inner insert rotary shaft is outside the contour range of the wheel hub to be detected;

[0012] When the end fixing seat is at the extreme position of outward movement, the trapezoidal column on the same side is at the extreme position of inward movement, and at this time the trapezoidal column is hidden in the main body of the side swing arm;

[0013] After the end fixing seat and the internal insertion shaft are moved to a position facing the center holes of a set of wheel hubs to be tested, the internal insertion shaft can be driven to be inserted into the center holes of the wheel hubs by the end fixing seat which can be synchronously and automatically moved laterally;

[0014] Before the inner insert shaft has been inserted into the center hole of the wheel hub and the outer pressure sleeve has not abutted against the outer end surface of the center hole of the wheel hub, the trapezoidal column has not extended to the outside of the side of the side swing arm, and because the position of the arched fixed frame always remains unchanged, the position coordinates of the arched insert frame and the side fixed arm that are fixed to the arched fixed frame can be considered by the control system to be in a fixed position. The control system can control the automatic lateral movement of the external connecting plate and the automatic rotation of the side swing arm, and use the clamping assembly to carry the wheel hub to be tested to the position opposite the trapezoidal column and the trapezoidal plug hole;

[0015] As the inner end of the outer pressure sleeve abuts against the outer end face of the hub center hole, by using the outer pressure sleeves symmetrically distributed on both sides and cooperating with the central positioning function of the inner inserted rotating shaft, on the one hand, the clamping work of the hub can be realized, and on the other hand, the trapezoidal column can be moved out of the main body of the side rotating arm and inserted into the trapezoidal jack;

[0016] Once again, through the automatically horizontally moving outer connecting plate, the side rotating arm is dragged, and the side fixing arm and the arched inserting frame connected to the side rotating arm through the insertion of the trapezoidal column into the trapezoidal jack are moved, so that the arched inserting frame is disengaged from the magnetic connection with the arched fixing frame, and at an appropriate position, the side rotating arm that rotates automatically drives the rotation of the clamped hub until the passive gear meshes with the active gear. During the process of the side rotating arm driving the hub to rotate to the detection position, the outer surface of the side fixing arm and the trapezoidal column inserted into the trapezoidal jack will be tangent to the smooth outer surface of the inner end of the safety sliding column, pushing the safety sliding column to retract, and after the passive gear and the active gear are meshed in place, the position of the trapezoidal column is just opposite to the safety sliding column;

[0017] At this time, the laser displacement sensor is facing the outer surface of the hub. Through the cooperative transmission formed by the automatically rotatable active gear and passive gear, the hub can be driven to rotate around the coaxially aligned inner inserted rotating shaft as the center, and in combination with the use of the arched inserting frame and the laser scanner that rotate with the side rotating arm to the detection position, dynamic balance detection can be carried out quickly and accurately to detect the defective position of the hub;

[0018] After the detection is completed, through the automatic movement of the end fixing seat, the outer pressure sleeve can be disengaged from the clamping of the hub, and the inner inserted rotating shaft gradually withdraws from the center hole of the hub. At this time, the detected hub can be removed manually or by using a manipulator;

[0019] And synchronously, the trapezoidal column will move in the direction of disengaging from the trapezoidal jack. Under the action of the self-elastic force of the safety sliding column, as the trapezoidal column retracts, the safety sliding column will extend and be inserted into the trapezoidal jack, so that the arched inserting frame is in a safe and stable position. After the detected hub is removed, as the end fixing seat and the inner inserted rotating shaft move inward again, the trapezoidal column can be reinserted into the trapezoidal jack and the safety sliding column can be pushed out;

[0020] Subsequently, with the automatic movement of the outer connecting plate and the automatic rotation of the side rotating arm, the arched inserting frame and the laser scanner can be repositioned to the position of magnetic connection with the arched fixing frame. And through the automatic outward movement of the end fixing seat and the inner inserted rotating shaft, not only can the release action of the trapezoidal column clamping the trapezoidal jack be formed, but also the inner inserted rotating shaft can return to the position waiting to be inserted into the hub center hole, waiting for the subsequent untested hub to be conveyed to the waiting detection position near the transfer component.

[0021] By adopting the above technical solutions, the present invention can achieve the following beneficial effects:

[0022] (1) The present invention is based on the transfer assembly and the conveying module, and adopts the method of magnetic plugging of the arched plug-in frame and the arched fixed frame fixed on the top of the conveying module, so as to first realize the detection of the position of the wheel hub to be detected in the conveying module, automatically extract the position coordinates of the center hole of the wheel hub, accurately control the automatic movement of the outer connecting plate and the automatic rotation of the side rotary arm, so that the end fixed seat can be accurately moved to the position opposite to the center hole of the wheel hub, thereby eliminating the problem of the inability to accurately locate the center hole of the wheel hub due to the conveying accuracy of the conveying module itself;

[0023] (2) In order to enable the laser scanner to also play a role in the dynamic balancing detection of the wheel hub, the present invention also provides a trapezoidal socket at one end of the side fixing arms fixed on both sides of the bottom end of the arched bracket, and a trapezoidal column is slidably connected with the end fixing seat in the main body of each set of side rotating arms, so that when the internal inserted rotating shaft is initially inserted into the center hole of the wheel hub with the automatic movement of the external connecting plate and the automatic rotation of the side rotating arm and the wheel hub is not clamped in place, the wheel hub can be moved to a position where the trapezoidal column and the trapezoidal socket are opposite, and after the end fixing seat drives the external pressure sleeve to complete the clamping of the wheel hub, the trapezoidal column can be inserted into the trapezoidal socket in place, so that the arched bracket and the arched fixing bracket can be separated in the process of transferring the wheel hub to the detection position, and the movement of the side rotating arm to the detection position facilitates the laser scanner to be moved to the position for dynamic balancing detection of the wheel hub, thereby achieving the dual purpose of the laser scanner;

[0024] (3) In order to prevent the arched bracket from being separated from the side swing arm during the process of removing the wheel hub after the dynamic balancing test is completed, the present invention also has safety seats symmetrically fixed to the top of the transfer assembly, and safety slide columns are elastically slid inward in each group of safety seats. Through the relative movement formed by the safety slide columns and the trapezoidal columns facing each other, the wheel hub can be safely released after the test is completed, protecting the arched bracket and the laser scanner from damage.

[0042] In the description of the present invention, it should be noted that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are 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 therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0043] like Figures 1-12 As shown, a motorcycle wheel hub dynamic balancing detection device based on three-dimensional scanning, a transfer assembly 1 and a conveying module 2 are arranged in parallel, the upper end of the transfer assembly 1 is symmetrically slidably connected with an outer connecting plate 104 that can move synchronously, a laser displacement sensor 108 is installed in the middle of one side of the top of the transfer assembly 1, and the conveying module 2 is used to batch-transport the wheel hubs to be detected to the transfer assembly 1;

[0044] The bottom end of the side rotary arm 402 is screwed to the outer side of the outer connecting plate 104, and the two groups of side rotary arms 402 can rotate synchronously. The automatically rotating driving gear 306 is symmetrically screwed to the top of the transfer component 1. The inner side of the top of each group of side rotary arms 402 is connected to an end fixed seat 503 that can automatically move laterally. The inner plug-in rotary shaft 504 is screwed to the end fixed seat 503. Each group of inner plug-in rotary shafts 504 is inserted with an outer pressure sleeve 505 and a passive gear 506. After the symmetrically distributed end fixed seats 503 are synchronously moved inward and inserted into the center hole of the wheel hub through the inner plug-in rotary shaft 504, the passive gear 506 on the same side is coplanar with the active gear 306.

[0045] An arched fixed frame 601 is fixed to one side of the upper end of the conveying module 2, and the arched plug-in frame 603 is magnetically plugged into the arched fixed frame 601. The laser scanner 610 is slidably connected to the arched plug-in frame 603 and can automatically move along the path formed by the arched plug-in frame 603. Side fixed arms 611 are fixed to both sides of the bottom end of the arched plug-in frame 603. Each set of side fixed arms 611 is provided with a trapezoidal socket 612 at one end close to the transfer component 1. The trapezoidal column 703 is slidably connected to the side rotary arm 402, and the trapezoidal column 703 on the same side is reversely driven and connected to the end fixed seat 503.

[0046] Furthermore, the laser scanner 610 can scan the wheel hub at any position within a certain range relative to the wheel hub, that is, the movement of the laser scanner 610 relative to the position of the wheel hub to be scanned within a reasonable range will not affect the scanning accuracy of the wheel hub;

[0047] The top of the transfer assembly 1 is also symmetrically fixed with safety seats 614, and each set of safety seats 614 is elastically slidably connected with a safety slide post 616;

[0048] Here’s how it works:

[0049] The conveying module 2 can place the wheel hubs to be inspected in batches and automatically convey them to the transfer assembly 1;

[0050] In the undetected state, the arched bracket 603 is magnetically connected to the arched fixed bracket 601 fixed on the upper end of the conveying module 2. At this time, the laser scanner 610 slidingly connected to the arched bracket 603 is in a position to detect the wheel hub conveyed in the conveying module 2. The laser scanner 610 can be used to scan and confirm the coordinate position of the center hole of a group of wheel hubs conveyed to the position close to the transfer component 1, and is used to feed back to the external control system to automatically control the lateral movement of the external connecting plate 104 and the automatic rotation of the side rotary arm 402, so as to drive the internal inserted rotary shaft 504 to move to a position opposite to the center hole of the wheel hub. In this process, the symmetrically distributed end fixed seat 503 is in the extreme position of outward movement, and the internal inserted rotary shaft 504 is outside the contour range of the wheel hub to be detected.

[0051] The purpose of the automatic lateral movement of the outer connecting plate 104 and the automatic rotation of the side rotary arm 402 is to transfer the wheel hub from the conveying position to the detection position;

[0052] And because the trapezoidal column 703 on the same side is connected to the end fixing seat 503 in reverse transmission, when the end fixing seat 503 is in the extreme position of outward movement, the trapezoidal column 703 on the same side is in the extreme position of inward movement, and at this time, the trapezoidal column 703 is hidden in the main body of the side swing arm 402;

[0053] After the end fixing seat 503 and the inner inserting swivel 504 are moved to a position facing the center hole of a set of wheel hubs to be inspected, the end fixing seat 503 which can move synchronously and automatically laterally can drive the inner inserting swivel 504 to be inserted into the center hole of the wheel hub;

[0054] Before the internal inserted rotating shaft 504 has been inserted into the center hole of the wheel hub and the external pressure sleeve 505 has not abutted against the outer end surface of the center hole of the wheel hub, the trapezoidal column 703 has not extended to the outside of the side of the side rotating arm 402. Since the position of the arched fixed frame 601 remains unchanged, the position coordinates of the arched inserted frame 603 and the side fixed arm 611 that are fixed to the arched fixed frame 601 can be considered by the control system to be in a fixed position. The control system can use the clamping assembly 5 to carry the wheel hub to be tested to the position opposite to the trapezoidal column 703 and the trapezoidal plug hole 612 by controlling the automatic transverse movement of the external connecting plate 104 and the automatic rotation of the side rotating arm 402.

[0055] As the inner end of the outer pressure sleeve 505 abuts against the outer end face of the hub center hole, by using the outer pressure sleeves 505 symmetrically distributed on both sides and cooperating with the central positioning function of the inner inserted rotating shaft 504, on the one hand, the clamping work of the hub can be realized, and on the other hand, the trapezoidal column 703 can be moved out of the main body of the side rotating arm 402 and inserted into the trapezoidal jack 612. During this process, the components in the conveying module 2 will not interfere with the clamping action of the outer pressure sleeve 505 and the action of the trapezoidal column 703 inserting from the main body of the side rotating arm 402 into the trapezoidal jack 612;

[0056] Once again, through the automatically horizontally moving outer connecting plate 104, the side rotating arm 402 is dragged, as well as the movement of the side fixing arm 611 and the arched insertion frame 603 connected to the side rotating arm 402 through the insertion of the trapezoidal column 703 into the trapezoidal jack 612, so that the arched insertion frame 603 is disengaged from the magnetic connection with the arched fixing frame 601, and at an appropriate position, the side rotating arm 402 that rotates automatically drives the rotation of the clamped hub until the passive gear 506 meshes with the active gear 306. During the process of the side rotating arm 402 driving the hub to rotate to the detection position, the outer surface of the side fixing arm 611 and the trapezoidal column 703 inserted into the trapezoidal jack 612 will be tangent to the smooth outer surface of the inner end of the safety sliding column 616, pushing the safety sliding column 616 to retract, and after the passive gear 506 and the active gear 306 are meshed in place, the position of the trapezoidal column 703 is just opposite to the safety sliding column 616;

[0057] At this time, the laser displacement sensor 108 is facing the outer surface of the hub. The cooperative transmission formed by the automatically rotatable active gear 306 and the passive gear 506 can drive the hub to rotate around the coaxial and facing inner inserted rotating shaft 504, and in cooperation with the use of the arched insertion frame 603 and the laser scanner 610 that rotate to the detection position with the side rotating arm 402, dynamic balance detection can be carried out quickly and accurately to detect the defective position of the hub;

[0058] After the detection is completed, through the automatic movement of the end fixing seat 503, the outer pressure sleeve 505 can be disengaged from clamping the hub, and the inner inserted rotating shaft 504 gradually withdraws from the center hole of the hub. At this time, the detected hub can be removed manually or by using a manipulator;

[0059] And synchronously, the trapezoidal column 703 will move in the direction of disengaging from the trapezoidal jack 612. Under the action of the self-elastic force of the safety sliding column 616, as the trapezoidal column 703 retracts, the safety sliding column 616 will extend and be inserted into the trapezoidal jack 612, so that the arched insertion frame 603 is in a safe and stable position. After the detected hub is removed, as the end fixing seat 503 and the inner inserted rotating shaft 504 move inward again, the trapezoidal column 703 can be reinserted into the trapezoidal jack 612 and push out the safety sliding column 616;

[0060] Subsequently, with the automatic movement of the outer connecting plate 104 and the automatic rotation of the side rotating arm 402, the arched insertion frame 603 and the laser scanner 610 can be repositioned to a position magnetically connected to the arched fixing frame 601. Through the automatic outward movement of the end fixing seat 503 and the inner insertion rotating shaft 504, not only can the release action of the trapezoidal column 703 clamping the trapezoidal insertion hole 612 be formed, but also the inner insertion rotating shaft 504 can return to the position waiting to be inserted into the hub center hole, waiting for the subsequent untested hubs to be transported to the position to be tested near the transfer assembly 1;

[0061] By operating in this way repeatedly, the automatic and high-precision detection of a batch of hubs placed in the conveying module 2 can be completed.

[0062] The specific structures of the transfer assembly 1 and the conveying module 2 are as Figure 2 and Figure 3 shown. On both sides of the upper end of the transfer base frame 101, linear slide rails 102 are transversely fixed in pairs. The outer connecting plates 104 on the same side are slidably connected to the linear slide rails 102 through linear sliders 103;

[0063] On both sides of the upper end of the transfer base frame 101, lead screws 105 are also transversely rotatably connected. The lead screw motors 106 are fixedly installed in the side frames of the transfer base frame 101. One end of the lead screw 105 on the same side is fixedly connected to the rotating shaft of the lead screw motor 106;

[0064] On the inner side surfaces of each group of outer connecting plates 104, lead screw sliders 110 are fixedly installed. The lead screw sliders 110 on the same side are in mating connection with the lead screws 105;

[0065] Driving the outer connecting plate 104 and the linear slider 103 to move horizontally along the linear slide rail 102 through the cooperation formed by the lead screw 105 and the lead screw slider 110 is a conventional technical means and will not be elaborated here;

[0066] A transverse mounting seat 107 is transversely fixed at the top of the transfer base frame 101. The laser displacement sensor 108 is installed in the middle of the main body of the transverse mounting seat 107, and the position of the laser displacement sensor 108 can be adjusted to facilitate accurate alignment with the outer surface of the hub;

[0067] On both sides of the top of the transfer base frame 101, stoppers 109 are fixed. When the side rotating arm 402 rotates to the detection position, that is, the position where the passive gear 506 meshes with the active gear 306, one side of the side rotating arm 402 just abuts against the stopper 109, thereby improving the self-supporting stability of the side rotating arm 402 during the rotation of the hub;

[0068] One end of the conveying chassis 201 is fixedly connected to one end of the transfer chassis 101 to jointly form a support frame. The top seat 202 is fixedly connected to the top end of the conveying chassis 201. The conveyor belt 204 is located at the inner lower end of the top seat 202. The side guiding rollers 205 are symmetrically arranged and rotatably connected to the inner upper end of the top seat 202.

[0069] Conveying rollers 203 are rotatably connected to both sides of the lower end of the top seat 202. Both ends of the conveyor belt 204 are respectively sleeved in different conveying rollers 203. The outer end of one group of conveying rollers 203 is connected with a rotation driving mechanism, which can drive the conveyor belt 204 to form an automatic conveying action.

[0070] A batch of hubs can be placed in the space formed by the upper surface of the conveyor belt 204 and the side guiding rollers 205 on both sides, and the conveyor belt 204 is used to form the automatic conveying work of the hubs.

[0071] The specific structure of the detection driving module 3 is as Figure 4 shown. The driving frame 301 is horizontally fixed to the top end of the transfer chassis 101. Active rotating seats 304 are symmetrically fixed to the top end of the horizontal mounting seat 107. A driving shaft 305 is horizontally rotatably connected to the top end of each group of active rotating seats 304. An active gear 306 and a rotating belt gear 307 are inserted and fixed in each group of driving shafts 305.

[0072] The driving motor 302 is fixedly installed on the top end of the driving frame 301. A fixed shaft seat 303 is also fixedly connected to the middle of the top end of the driving frame 301. The rotating shaft of the driving motor 302 is rotatably connected to the fixed shaft seat 303, which can improve the rotation accuracy. Driving belt gears 308 are symmetrically inserted and fixed in the rotating shaft of the driving motor 302.
