Description

Technical Field

[0001] The invention relates to the technical field of motorcycle assembly, in particular to a laser scanning correction device for welding deformation of a motorcycle frame. Background Art

[0002] The motorcycle frame is the core structure that supports the engine, suspension system and other components. Its design and manufacturing directly affect the performance, safety and comfort of the vehicle. It is usually made of materials such as steel pipes or aluminum alloys and assembled by welding.

[0003] During welding, local high temperatures can cause the material to expand, and then contract after cooling, which in turn causes thermal deformation and dimensional deviations of frame parts. Specific reasons include:

[0004] 1. Thermal stress: During welding, the local area expands due to heat, and contracts after cooling, generating internal stress and causing deformation;

[0005] 2. Uneven heating: The temperature difference between the welding area and the non-welding area causes deformation;

[0006] 3. Material properties: Different materials have different thermal expansion coefficients, and the degree of deformation after welding varies;

[0007] 4. Welding process: Improper parameters such as welding speed, current, voltage, etc. will aggravate deformation.

[0008] The above reasons will cause dimensional deviations in the motorcycle frame after welding, such as deviations from the design values ​​of wheelbase, suspension mounting point position, engine mounting hole position, etc., resulting in other components (such as engine, suspension system, wheels, etc.) being unable to be installed correctly, or even requiring forced assembly, affecting the performance of the entire vehicle. Summary of the invention

[0009] The purpose of the present invention is to provide a laser scanning correction device for welding deformation of a motorcycle frame. By utilizing the joint action of a first laser scanner and a second laser scanner, the frame before correction can be positioned and clamped, and the position of the mounting sleeve at the rear end of the frame can be scanned. In combination with the use of a correction column assembly and a safety rotary sleeve assembly, the thermal deformation of the motorcycle frame caused by welding can be corrected safely and with high precision, thereby eliminating the adverse effects caused by welding thermal deformation.

[0010] The objective of the present invention is achieved through such a technical solution, a laser scanning correction device for welding deformation of a motorcycle frame, comprising a base assembly, an insert component, a mounting hole scanning assembly, a correction plug column assembly and a safety rotary sleeve assembly, the spindle clamping assembly comprises a spindle seat, the insert component comprises a middle slide seat, the mounting hole scanning assembly comprises a second laser scanner, the correction plug column assembly comprises an inner support wing and a correction column, and the safety rotary sleeve assembly comprises an auxiliary support wing;

[0011] The spindle seat is fixed on one side of the top of the base assembly, and a pair of chucks that move synchronously towards each other are installed on one side of the top of the base assembly. The middle slide is fixed on the other side of the top of the base assembly, and each group of middle slides is slidably connected with coaxial positioning columns that move synchronously towards each other; the second laser scanner is rotatably arranged on one side of the middle slide and is transmission-connected with the positioning column on the same side;

[0012] The other side of the top of the base assembly is also vertically slidably connected with a pair of lifting frames, and a sleeve frame is fixed in the main body of each set of lifting frames. The inner support wings are planted on both sides of the inner surface of the sleeve frame, and the correction column is lifted in the inner support wings;

[0013] A rotary sleeve is screwed to the inner middle of each set of sleeve frames, and the auxiliary supporting wings are planted on the inner surface of the rotary sleeve.

[0014] The use process of the technical solution of the present invention is as follows:

[0015] Insert the spindle sleeve at the front end of the frame into the spindle seat, and rotate the rear end of the frame to adjust the rotation angle of the frame relative to the spindle seat, so as to facilitate adjusting the installation sleeve at the rear end of the frame to a position facing the correction column;

[0016] Furthermore, since the correction column is wrapped in a closed structure composed of the inner support wing and the auxiliary support wing, even if the rotation angle of the frame is not in place or the welding deformation of the mounting sleeve at the rear end of the frame is large, the correction column can be smoothly inserted into the mounting sleeve at the rear end of the frame;

[0017] After the frame is rotated and adjusted relative to the spindle seat to a certain position, the driving mechanism connected to the chuck is started to initially clamp the spindle sleeve of the frame, so that the frame can still be rotated and adjusted after being subjected to a certain force;

[0018] Subsequently, by starting the driving mechanism connected to the positioning column, the positioning column can be extended from the inside into the inner hole of the mounting sleeve at the rear end of the frame. Since the outer diameter of the positioning column is smaller than the inner hole size of the mounting sleeve at the rear end of the frame, within the deformation range caused by thermal welding of the frame, after the frame itself is rotated and adjusted to the right position relative to the spindle seat, the movement of the positioning column will not touch the frame itself.

[0019] In the process of placing the vehicle frame, the positioning column is at the minimum limit position of inward retraction. After the vehicle frame is placed and rotated and adjusted to the right position relative to the spindle seat, the horizontal movement of the positioning column can drive the automatic rotation of the second laser scanner on one side. The rotation of the second laser scanner facing the different groups can be used to scan the installation sleeve at the rear end of the vehicle frame relative to the spindle seat.

[0020] Thus, the position coordinate relationship of the mounting sleeve at the rear end of the frame relative to the main shaft sleeve at the front end of the frame before correction can be established, and compared with the design coordinate relationship to guide the correction of the mounting sleeve at the rear end of the frame to a reasonable relative position tolerance range with the main shaft sleeve at the front end;

[0021] Subsequently, the main shaft sleeve of the frame is clamped by the chuck to fix the front end of the frame, and each set of correction columns is inserted into the mounting sleeve facing the rear end of the frame. Combined with the real-time scanning of the position of the mounting sleeve at the rear end of the frame relative to the main shaft seat formed by the second laser scanner, external forces in different directions are applied to the outer ends of the correction columns. By using the principle of lever, the correction work of the motorcycle frame after welding deformation can be completed.

[0022] By adopting the above technical solution, the present invention can achieve the following beneficial effects:

[0023] (1) The present invention arranges a pair of automatically lifting and lowering lifting frames at the top of the base assembly, and inner supporting wings are planted on both sides of the inner surface of the sleeve fixed in the lifting frame body, and auxiliary supporting wings are also planted on the inner surface of the rotating sleeve screwed in the middle of the inner surface of the sleeve. The correction column can be placed in the supporting space formed by the inner supporting wings and the auxiliary supporting wings. The main purpose is to form a buffer protection for the correction column during the real-time correction process to prevent the correction column from being separated when subjected to force and damaging other related components;

[0024] (2) At the same time, after the rotary sleeve is rotated to form a closed wrapping structure of the correction column with the auxiliary support wing and the inner support wing, the correction column can be dragged to move the position of the correction column, which can not only move the correction column to a position where it does not interfere with the placement of the frame to be corrected, but also move the correction column to a position where it is convenient to insert into the installation sleeve at the rear end of the frame;

[0025] (3) Another purpose of the rotatable sleeve of the present invention is that after the rotatable sleeve is rotated until the structure composed of the auxiliary support wings and the inner support wings is opened, it can form an effect of facilitating the removal and placement of the correction column;

[0026] (4) The horizontal lateral movement of the positioning column of the present invention can not only synchronously drive the second laser scanner to form a rotary scanning effect, but also can improve the degree of automation by inserting the positioning column into the installation sleeve at the rear end of the frame after the frame is calibrated.

DETAILED DESCRIPTION

[0051] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0052] 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.

[0053] like Figure 1-Figure 15 As shown, a laser scanning correction device for welding deformation of a motorcycle frame is provided. A spindle seat 201 is fixedly installed on one side of the top of a base assembly 1 for inserting the spindle sleeve of the frame. A pair of chucks 203 that move synchronously toward each other are also installed on one side of the top of the base assembly 1 for clamping the spindle sleeve of the frame. A middle slide seat 303 is fixedly connected to the other side of the top of the base assembly 1. A coaxial positioning column 302 that moves synchronously toward each other is slidably connected in each group of middle slide seats 303. The number of middle slide seats 303 is determined according to the number of mounting sleeves at the rear end of the motorcycle frame.

[0054] The second laser scanner 402 is rotatably mounted on one side of the middle slide 303 and is in transmission connection with the positioning column 302 on the same side, so that the second laser scanner 402 can be driven to rotate while the positioning column 302 moves;

[0055] A pair of lifting frames 501 are vertically slidably connected to the other side of the top of the base assembly 1. A sleeve frame 503 is fixed in the main body of each set of lifting frames 501, and the number of sleeve frames 503 fixed in the main body of the single-side lifting frame 501 is consistent with the number of the middle slide seat 303. The inner support wings 504 are planted on both sides of the inner surface of the sleeve frame 503. The correction column 505 is lifted in the inner support wings 504, and the inner contour formed by the inner support wings 504 can prevent the correction column 505 from easily falling out after being inserted into the inner support wings 504; and after the main shaft sleeve of the frame is inserted into the main shaft seat 201 and the chuck 203 is clamped to clamp the main shaft sleeve in place, the correction column 505 can be adjusted and inserted into the installation sleeve of the opposite frame;

[0056] The inner middle part of each set of sleeves 503 is screwed with a rotary sleeve 602, and the auxiliary support wings 603 are planted on the inner surface of the rotary sleeve 602. With the rotation of the rotary sleeve 602, the auxiliary support wings 603 can form a closed wrapping structure with the inner support wings 504 for the correction column 505, and can also be opened together to facilitate the removal of the correction column 505.

[0057] Here’s how it works:

[0058] The correction principle of the device is to use the main shaft sleeve at the front end of the motorcycle frame as a reference to correct the position of the mounting sleeve at the rear end of the frame relative to the main shaft sleeve;

[0059] And multiple installation sleeves that are close to the rear end of the frame can be regarded as one. This is because the position at a small distance is very limited due to welding. Therefore, when calibrating, for multiple installation sleeves that are close to each other, just select one group;

[0060] Insert the spindle sleeve at the front end of the frame into the spindle seat 201, and rotate the rear end of the frame to adjust the rotation angle of the frame relative to the spindle seat 201, so as to facilitate adjusting the mounting sleeve at the rear end of the frame to a position facing the correction column 505;

[0061] Furthermore, since the correction column 505 is wrapped in the closed structure composed of the inner support wing 504 and the auxiliary support wing 603, the correction column 505 is equivalent to being in a suspended state. Even if the rotation angle of the frame is not in place, or the welding deformation of the mounting sleeve at the rear end of the frame is large, the correction column 505 can be smoothly inserted into the mounting sleeve at the rear end of the frame.

[0062] After the frame is rotated and adjusted relative to the spindle seat 201 to a certain position, the driving mechanism connected to the clamp 203 is started to initially clamp the spindle sleeve of the frame, so that the frame can still be rotated and adjusted after being subjected to a certain force;

[0063] Subsequently, by starting the driving mechanism connected to the positioning column 302, the positioning column 302 can be extended from the inside into the inner hole of the mounting sleeve at the rear end of the frame. Since the outer diameter of the positioning column 302 is smaller than the inner hole size of the mounting sleeve at the rear end of the frame, within the deformation range caused by thermal welding of the frame, after the frame itself is rotated and adjusted to the right position relative to the spindle seat 201, the movement of the positioning column 302 will not touch the frame itself.

[0064] In the process of placing the vehicle frame, the positioning column 302 is at the minimum limit position of inward retraction. After the vehicle frame is placed and rotated and adjusted to the right position relative to the spindle seat 201, the horizontal movement of the positioning column 302 can drive the automatic rotation of the second laser scanner 402 on one side. The rotation of the second laser scanner 402 facing different groups can be used to scan the mounting sleeve at the rear end of the vehicle frame relative to the spindle seat 201.

[0065] Thus, the position coordinate relationship of the mounting sleeve at the rear end of the frame relative to the main shaft sleeve at the front end of the frame before correction can be established, and compared with the design coordinate relationship to guide the correction of the mounting sleeve at the rear end of the frame to a reasonable relative position tolerance range with the main shaft sleeve at the front end;

[0066] Before the positioning column 302 moves outward from the minimum limit position of inward retraction to the installation sleeve at the rear end of the frame, the number of rotations formed by the second laser scanner 402 is sufficient to support it to completely scan the installation sleeves on both sides of the rear end of the frame;

[0067] Subsequently, the main shaft sleeve of the frame is clamped by the chuck 203, so that the front end of the frame is in a fixed state, and each group of correction columns 505 is inserted into the mounting sleeve of the rear end of the frame facing it. In combination with the real-time scanning of the position of the mounting sleeve of the rear end of the frame relative to the main shaft seat 201 formed by the second laser scanner 402, external forces in different directions are applied to the outer ends of the correction columns 505. By using the principle of lever, the correction work of the motorcycle frame after welding deformation can be completed;

[0068] After the calibration is completed, the calibration column 505 inserted into the mounting sleeve can be pushed out laterally by the positioning column 302 which can automatically move horizontally and extends into the mounting sleeve at the rear end of the frame. In conjunction with the automatic lifting and lowering movement of the lifting frame 501, the sleeve frame 503 and the calibration column 505 can be moved to a position where they do not hinder the removal of the frame.

[0069] The specific structure of the base assembly 1 and the spindle clamping assembly 2 is as follows: Figure 2 and Figure 3 As shown, the top of the base 101 is a step-type structure to adapt to the three-dimensional structure of the motorcycle workshop. The first laser scanner 102 is installed and fixed at the middle of the top of the base 101 and is located opposite to the crossbeam of the motorcycle frame. The first laser scanner 102 scans the crossbeam of the motorcycle frame in real time, so that the rotation position of the motorcycle frame relative to the main shaft seat 201 can be quickly adjusted;

[0070] The spindle seat 201 and the main frame 202 are fixed to one side of the top of the base 101, and the chuck 203 is installed inside the main frame 202;

[0071] A bottom limit sleeve 204 is fixedly sleeved on the lower end of the outer side of the main shaft seat 201 to limit the insertion position of the motorcycle frame;

[0072] The main frame 202 is fixedly connected with clamping rails 205 in pairs, and the ends of each set of clamps 203 are fixedly connected with clamping sliders 206 in pairs, and the clamping sliders 206 on the same side are slidably connected with the clamping rails 205;

[0073] The two ends of the clamping screw 207 are respectively rotatably connected to the main body of the main frame 202, and a screw slider 208 is fixed to the middle of the end of each set of chucks 203, and the two sets of screw sliders 208 are both connected with the clamping screw 207;

[0074] A lead screw motor 209 is also mounted and fixed on one end of the outer side surface of the main frame 202, and one end of the clamping lead screw 207 passes through the main body of the main frame 202 and is fixedly connected to the rotating shaft of the lead screw motor 209;

[0075] The clamping screw 207 is a double-ended screw structure with left-handed and right-handed threads at both ends respectively, so that when the clamping screw 207 is driven by the screw motor 209 to rotate in one direction, the two sets of screw sliders 208 maintain relatively opposite movement. This is the prior art and will not be elaborated here.

[0076] The specific structure of the insert component 3 and the mounting hole scanning component 4 is as follows: Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the bottom of the middle seat 301 is fixed to the top of the base 101, the middle sliding seat 303 is fixed to the top of the middle seat 301, the special-shaped sliding hole 304 is opened in the middle sliding seat 303, and the end of each group of positioning columns 302 is fixed with a special-shaped sliding column 305, and the paired structure composed of the special-shaped sliding column 305 is slidably connected in the special-shaped sliding hole 304, and will not move beyond the range of the special-shaped sliding hole 304, and each group of special-shaped sliding columns 305 are installed and fixed on the outer surface of the inner rack 306, and one side of each group of inner rack 306 is meshed with an opening and closing gear 308, and an opening and closing rotary seat 309 is installed and fixed at the bottom end of the main body of the middle seat 301, and the opening and closing rotary shaft 307 is rotatably connected in the opening and closing rotary seat 309, and the opening and closing gear 308 is plugged and fixed at the top of the opening and closing rotary shaft 307, and the toothed belt wheel 310 is plugged and fixed at the bottom end of the opening and closing rotary shaft 307;

[0078] By starting the opening and closing motor 312 to drive the opening and closing rotating shaft 307 of the same group to rotate synchronously and in the same direction, the opening and closing gears 308 arranged on both sides of the slide seat 303 of the same group can be rotated synchronously and in the same direction, so that the two groups of special-shaped slide posts 305 slidably connected in the slide seat 303 of the same group can maintain relative reverse movement;

[0079] The scanning rotary seat 403 is fixedly installed on the top of the middle seat 301, and the scanning gear 404 is rotatably connected to the scanning rotary seat 403 and meshes with the opening and closing gear 308 on the same side.

[0080] When the opening and closing gear 308 rotates, the rotary tube 401 and the second laser scanner 402 can be driven to rotate through the coordinated transmission formed with the scanning gear 404, so that the second laser scanner 402 can scan the installation sleeves distributed on both sides of the rear end of the frame.

[0081] The specific structure of the correction pin assembly 5 and the safety sleeve assembly 6 is as follows: Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, the bottom end of the lifting frame 501 is fixed with lifting slides 502 in pairs, and the lifting slide 507 is fixedly installed in the top body of the base 101.

The clamping column 506 is coaxially connected to the end of the correction column 505.

[0082] The lifting hydraulic cylinder 509 is connected to the hydraulic control system in the device, and can drive the lifting frame 501 and the sleeve frame 503 connected to the main body of the lifting frame 501 to form a lifting movement, thereby realizing the adjustment of the height of the correction column 505;

[0083] The rotary groove 601 is provided in the middle of the inner surface of the sleeve 503, the rotary sleeve 602 is rotatably connected to the rotary groove 601, and a middle rotary groove 604 is provided in the middle of the main body of each set of sleeves 503, a magnetic middle rotary block 605 is fixedly connected to the outside of the rotary sleeve 602, and magnetic positioning blocks 606 are provided on both sides of the middle rotary groove 604, the magnetic positioning blocks 606 are fixedly connected to the outside of the sleeve 503, and the magnetic middle rotary block 605 is slidably connected in the middle rotary groove 604;

[0084] By moving the magnetic center rotation block 605 to slide in the center rotation groove 604, the rotation of the rotation sleeve 602 can be driven, so that the auxiliary support wing 603 and the inner support wing 504 cooperate to form different working states;

[0085] The magnetic center rotation block 605 is magnetically attracted to the magnetic positioning blocks 606 on both sides, which also facilitates keeping the auxiliary support wings 603 in different working states.

[0086] like Fig.12 , Fig.13 , Fig.14 and Fig.15As shown, a correction component 7 is also installed at the top of the base 101, which is used to apply a universal lever force to the clamping column 506 at the end of the correction column 505.

[0089] After starting any one of the transverse motors 704, the transverse gear 705 can form a coordinated transmission with the transverse rack 703 at a fixed position, driving the transverse seat 702 to move horizontally, so as to adjust the horizontal position of the vertical slide 706 slidably connected to the transverse seat 702 and the rotary disk 709 rotatably connected to the vertical slide 706;

[0090] A spherical fixed seat 714 is fixed to the middle of the other side of the rotary disk 709, and a spherical rotating seat 720 is fixed to the end of the correction seat 713.

[0091] Similarly, the vertical hydraulic cylinder 708 and the correction hydraulic cylinder 717 are connected to the hydraulic control system in the device. By starting the vertical hydraulic cylinder 708, the vertical slide 706 and the rotary plate 709 rotatably connected to the vertical slide 706 can also be driven to adjust the vertical position.

[0092] At the same time, by synchronously starting the correction hydraulic cylinders 717 on both sides of the correction seat 713, the correction hydraulic cylinders 717 on both sides of the correction seat 713 can be made to act in coordination, with one group of correction hydraulic cylinders 717's telescopic rods extending and the other group of correction hydraulic cylinders 717's telescopic rods being synchronously retracted, thereby stably driving the correction seat 713 to form a spinning action in any direction on the card column 506 inserted into the card slot 718. Since the head end of the correction column 505 is inserted into the mounting sleeve of the frame, the lever effect of the correction seat 713 on the correction column 505 can quickly correct the position of the mounting sleeve of the frame relative to the main shaft sleeve.

[0093] In addition, the above-mentioned electronic control components and the first laser scanner 102 and the second laser scanner 402 are all connected to the control system in the device, which can realize automatic scanning of the motorcycle frame and correction of the force application.
