Description

Technical Field

[0001] This utility model relates to the field of welding processing equipment technology, specifically to an anti-slip motorcycle frame welding robot. Background Technology

[0002] As a crucial load-bearing component of the motorcycle frame, the welding quality directly affects the structural strength and operational safety of the entire vehicle. With the continuous improvement of manufacturing automation, traditional manual welding processes are gradually being replaced by automated welding robots. Among these, the solution of using a six-axis servo welding robotic arm combined with a multi-axis positioning system for multi-angle welding operations is widely used.

[0003] In the prior art, a common motorcycle frame welding device typically includes a welding robotic arm, a rotary positioner, and a workpiece fixing fixture. Existing welding worktables with frame clamping mechanisms use cylinders to push latches to clamp and position the frame, assisting in partially automating the welding operation.

[0004] However, this type of welding system generally suffers from the following technical shortcomings: Poor adaptability of clamping structure: Due to the large number of motorcycle frame models, the structure has deformation areas with different cross sections and angles. Most existing clamping structures are rigid positioning, which makes it difficult to achieve quick clamping and high adaptability clamping for different structures, resulting in frequent clamping changes or large positioning errors.

[0005] Poor stability of the locking mechanism: Some clamping devices are susceptible to thermal deformation, vibration and loosening during the welding process, which causes micro-displacement of the frame during welding, affecting the consistency of the weld and the welding quality, and reducing production stability.

[0006] In summary, existing motorcycle frame welding systems lack a highly stable clamping component that can achieve multi-axis linkage and flexible adaptability. There is an urgent need to propose an innovative technical solution that can effectively improve the welding positioning accuracy and clamping stability of the frame to meet the actual needs of automated manufacturing systems for welding processes of multiple models and postures. Utility Model Content

[0007] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0008] Therefore, the technical solution adopted by this utility model is as follows: an anti-slip motorcycle frame welding robot, including a welding robotic arm, a servo positioner, a positioning bed, and multiple detachable positioning components, with the specific structure as follows: In a preferred example, the welding robotic arm is further configured as follows: It is a multi-axis servo-driven structure with a welding head at its end effector for precise welding of the motorcycle frame weld seams, possessing multi-degree-of-freedom flexible control characteristics; a servo positioner is located at the bottom of the robot for multi-axis attitude adjustment of the positioning bed, enabling omnidirectional welding path adjustment of the frame, with its two ends reliably connected to the positioning bed via servo discs; the positioning bed adopts a grid structure, with several longitudinal and transverse bars intersecting to form a grid frame, which enhances the overall load-bearing capacity and facilitates the subsequent installation of multiple positioning components to adapt to different frame structures; the positioning components include a locking seat, a positioning base, a clamping lug, and a locking lug plate. The locking seat is installed on the horizontal and vertical bars of the positioning bed frame via a sleeve structure; the bottom of the positioning seat is provided with a sliding groove that mates with the locking seat, ensuring that the positioning seat can be quickly installed and removed on the bed frame; one end of the lug is rotatably connected to the positioning seat, and the other end is connected to the connecting plate, and the other end of the connecting plate is rotatably connected to the locking lug plate, which is driven by the linkage mechanism to complete the locking operation; both ends of the locking lug plate are provided with latches and levers for locking and unlocking actions, and the surface of the locking lug plate is provided with deformation gaps, giving it good elastic deformation ability.

[0009] In a preferred embodiment, the positioning seat is further configured as follows: the positioning seat is a U-shaped groove structure with a retaining lug and a buckle groove on both sides; the buckle rod is inserted into the buckle groove in the rotating state to achieve quick clamping; the lever cooperates with the spring clip on the retaining lug to lock and prevent the positioning component from loosening during the welding process.

[0010] In a preferred embodiment, the deformation gap is further configured such that it is arranged in a reciprocating staggered manner on the surface of the locking lug plate, so that the locking lug plate has elastic deformation during the clamping process, which enhances the fastening stability and clamping force. The overall structure can generate elastic pre-pressure on the outer edge of the frame, preventing the frame from sliding or slightly shifting after being heated, and improving welding accuracy.

[0011] The beneficial effects achieved by this utility model are as follows: 1. In this utility model, the welding robotic arm works in conjunction with the servo positioner to achieve automated welding operations on motorcycle frames at multiple angles and in multiple postures, improving welding accuracy and consistency, avoiding the problem of weld seam offset caused by mismatch in workpiece posture, significantly improving welding efficiency and quality, and is suitable for flexible manufacturing scenarios of multiple models of frames.

[0012] 2. In this utility model, the positioning component adopts a multi-linkage structure of "locking seat + positioning seat + clamping ear + locking ear plate + connecting plate" to achieve stable clamping of different cross sections or curved parts during the frame welding process; its locking structure has elastic deformation capability and self-locking function, which can not only absorb the stress impact caused by installation deviation, but also prevent the locking structure from loosening due to vibration, thereby ensuring the rigidity stability and positioning accuracy of the frame during the welding process, and has good anti-slip capability and adaptability.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0016] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0017] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing an anti-slip motorcycle frame welding robot.

[0018] Combination Figures 1-5 As shown, the present invention provides an anti-slip motorcycle frame welding robot, including a welding robotic arm 100, a servo positioner 110, a positioning bed 200, and several positioning components 300 that can be detachably installed on the surface of the positioning bed 200.

[0019] The welding robotic arm 100 is a multi-axis servo robotic arm structure with a welding head at its end, enabling automated welding of motorcycle frames. The servo positioner 110 works in conjunction with the positioning bed 200 to drive the positioning bed 200 to perform multi-axis displacement or angular deflection, thereby enabling precise welding of the motorcycle frame in multiple workstation spatial postures.

[0020] The positioning bed frame 200 is a grid structure, formed by the intersecting arrangement of several longitudinal and transverse bars to create a stable, grid-like rigid support surface. Both ends of the positioning bed frame 200 are equipped with rudder discs 210 for connection and fixation to the output end of the servo positioner 110.

[0021] The positioning component 300 includes a locking seat 310, a positioning seat 320, a retaining lug 330, and a retaining lug plate 340, and is also equipped with a connecting plate 350. The specific structure is as follows: The locking seat 310 can be stably installed by adapting to the surfaces of the crossbars and longitudinal bars of the positioning bed frame 200. In a preferred embodiment, the top surface of the locking seat 310 is provided with a sliding fastener, and the bottom surface of the positioning seat 320 is provided with a sliding fastener groove that mates with the sliding fastener, so that the positioning seat 320 can be detachably installed on the locking seat 310.

[0022] The positioning seat 320 has a U-shaped cross-section and is used to support and position the tubular part of the motorcycle frame. Its two ends have a buckle groove 321 and a connecting structure hinged to the lug 330, respectively. One end of the lug 330 is rotatably connected to the positioning seat 320, and the other end is rotatably connected to the connecting plate 350; the other end of the connecting plate 350 is rotatably connected to the bottom of the locking lug plate 340.

[0023] The locking lug plate 340 is provided with a latch 341 and a lever 342 at both ends. When positioning, the latch 341 is inserted into the latch groove 321 provided on the top surface of the positioning seat 320 to complete the initial locking. The end of the lever 342 drives the connecting plate 350 through rotational movement, thereby controlling the locking lug plate 340 to rotate around its hinge point to realize the latching or unlocking operation.

[0024] like Figure 4 and Figure 5 As shown, the surface of the locking lug plate 340 is provided with several deformation gaps 343. The deformation gaps 343 adopt a reciprocating staggered arrangement structure, which has a certain elastic deformation capacity. It can provide deformation buffer and stress absorption function during locking or unlocking, effectively reducing mechanical damage caused by forced clamping.

[0025] Furthermore, to prevent the locking state from loosening, the surface of the latch 330 is also provided with a spring clip structure that engages with the lever 342. After the latch plate 340 is inserted into the latch groove 321 via the latch rod 341, the mechanical locking of the locking structure can be achieved by the engagement of the lever 342 with the spring clip, thereby ensuring that the positioning component 300 does not slip or loosen during the welding operation.

[0026] In the structure described in this utility model, the welding robotic arm 100 and the servo positioner 110 work together to complete the precise welding of the motorcycle frame in multi-axis postures; the positioning component 300 achieves high adaptability and high stability clamping of tubular frames with different cross-sections through a multi-level linkage mechanism. In particular, the linkage control structure formed by the locking lug plate 340 and the connecting plate 350 makes the operator's actions simple and efficient during clamping and unlocking, avoiding the risk of human error.

[0027] Working principle and usage process of this utility model: In the welding process, this invention first uses a servo positioner 110 to drive the positioning bed 200 for multi-axis spatial attitude adjustment, so that the welding part is at the optimal welding angle. The motorcycle frame is pre-mounted on the positioning bed 200 and is stably clamped and positioned by several positioning components 300.

[0028] Each positioning component 300 consists of a locking seat 310, a positioning seat 320, a clamping lug 330, and a locking lug plate 340. During clamping, the positioning seat 320 and the clamping lug 330 cooperate to form a covering structure for limiting and nesting the outer wall of the motorcycle frame tubes. The locking lug plate 340 is connected to the end of the clamping lug 330 via a connecting plate 350. The latching bar 341 on the locking lug plate 340 engages with the latching groove 321 on the positioning seat 320, while the lever 342 engages with the spring clip on the clamping lug 330 to lock the engagement. The deformation gap 343 provides a certain elastic buffer, making the engagement process smoother and preventing impact breakage. The locking seat 310 and the positioning seat 320 are connected by a sliding buckle structure, which allows for quick disassembly and replacement.

[0029] Once the frame is positioned, the welding robotic arm 100 is activated, and its multi-axis actuator controls the welding head to perform welding operations on the key nodes of the motorcycle frame along a predetermined trajectory. Because the positioning component 300 can reliably lock the frame components, the frame will not loosen, misalign, or slip even under the multi-angle flipping operation of the servo positioner 110, thus ensuring the alignment accuracy and welding consistency of the weld.

[0030] After welding, the spring clip constraint is released by the lever 342, and the connecting plate 350 drives the locking lug plate 340 to rotate, causing the locking rod 341 to disengage from the locking groove 321, thus completing the unlocking. At the same time, the positioning seat 320 and the locking clamp seat 310 can be slid apart to achieve quick disassembly of the frame. The above process is repeated cyclically, which can efficiently achieve precise positioning, stable welding and quick replacement of different types of frames.

[0031] In summary, through the coordinated control and structural cooperation between the welding robotic arm 100, the servo positioner 110, the positioning bed 200, and the multi-functional positioning component 300, the automation level and operational accuracy of motorcycle frame welding are significantly improved, and manual intervention is reduced. It has good prospects for industrial application and batch welding capability.
