Description

Technical Field

[0001] This utility model relates to the field of motorcycle frame processing technology, and in particular to a high-stability motorcycle frame processing fixing fixture. Background Technology

[0002] The motorcycle frame, as the core load-bearing structure of the entire vehicle, is known as the "skeleton" of the motorcycle. It not only supports and mounts key components such as the engine, suspension system, and fuel tank, but also directly affects the vehicle's driving stability, handling performance, and safety. During motorcycle manufacturing, the machining precision and assembly quality of the frame are crucial; even minor deviations can lead to a decrease in overall vehicle performance or even safety hazards. Therefore, in the welding, drilling, riveting, and assembly processes of the frame, highly stable fixing fixtures must be used to precisely position and reliably clamp the frame or its components to ensure the machining accuracy and consistency of each process.

[0003] Utility model patent CN 118664216 A discloses a fixture including a worktable, a fixing component and a clamping device. It achieves initial positioning by embedding a positioning post into the wiring cavity, and then uses a quick clamp to drive the clamping component to press the plate against the outer wall of the main frame to form a limit, thereby improving processing accuracy and reducing production costs.

[0004] However, this device has a significant technical flaw: its clamping components cannot be adjusted horizontally after clamping, resulting in a fixed position of the clamped sheet metal, making it difficult to adapt to the needs of main frames with different widths or structural layouts. When dealing with various models or non-standard motorcycle frames, the entire set of clamps must be replaced or complex mechanical adjustments must be made, severely restricting the flexibility and versatility of the production line.

[0005] Therefore, to address the shortcomings of existing technologies, we urgently need a highly stable motorcycle frame machining and fixing fixture to solve this problem. This new fixture should be able to achieve flexible horizontal adjustment of the clamping components while ensuring high-strength clamping and precise positioning, adapting to main frames of different sizes and specifications. This would improve the fixture's versatility and adaptability, while reducing clamping errors and assembly stress, significantly improving processing efficiency and product quality. It would better meet the demands of modern, multi-variety, small-batch motorcycle production, providing strong support for the intelligent and flexible development of the motorcycle manufacturing industry. Utility Model Content

[0006] The purpose of this utility model is to provide a highly stable motorcycle frame processing and fixing fixture, which solves the problem that in the prior art, the clamping components cannot be adjusted in the horizontal direction after clamping, resulting in the fixed position of the clamped plate and making it difficult to adapt to the main frame requirements of different widths or structural layouts.

[0007] To achieve the above objectives, this utility model provides a high-stability motorcycle frame processing and fixing fixture, including a worktable, a positioning cylinder, and a support frame. The positioning cylinder is located on one side of the top of the worktable, and the support frame is located on the other side of the top of the worktable. A main frame is located at the center of the inside of the positioning cylinder, and several clamping structures are provided on the inner ring of the positioning cylinder. The top of the support frame is slidably connected to a sliding rod, one end of which is connected to a crossbar. Two sliding members are slidably connected to the outer ring of the crossbar. Each sliding member has a clamping frame connected to one side. The top of the sliding member is provided with a positioning structure that is detachably connected to the top of the crossbar. Each clamping frame has a clamping plate on one side inside. One side of the clamping plate is rotatably connected to an adjusting screw with one end threaded through the clamping frame. Each clamping frame has a plate inside. One side of the support frame is connected to a bracket, and the top of one side of the bracket is provided with a pushing structure that cooperates with the sliding rod.

[0008] The clamping structure includes an abutment plate and an abutment screw rotatably connected to one side of the abutment plate, with one end of the abutment screw threaded through the side wall of the positioning cylinder.

[0009] The sliding component includes a sliding frame that slides with the outer ring of the crossbar, and a sleeve is fixedly connected to the top of the support frame. The sliding rod is slidably connected to the inside of the sleeve.

[0010] One end of the contact screw is fixedly connected to a handle, and the outer ring of the handle has several anti-slip grooves.

[0011] The positioning structure includes a positioning screw with one end threaded through the top of the sliding frame, and the top of the crossbar has several positioning holes that are adapted to the positioning screw.

[0012] The bracket is L-shaped, with one end of the horizontal section of the bracket fixedly connected to the side wall of the support frame. The pushing structure includes a pushing cylinder installed on one side of the vertical section of the bracket, and the output end of the pushing cylinder is connected to the end of the sliding rod.

[0013] This utility model discloses a high-stability motorcycle frame processing and fixing fixture. Through the sliding cooperation of the sliding component and the crossbar, and the setting of the detachable positioning structure, the position of the clamping frame can be flexibly adjusted according to the actual size and structural layout of the main frame, without the need to replace the entire fixture or perform complex disassembly and assembly. This significantly improves the fixture's adaptability to different models of motorcycle frames and enhances the flexibility and versatility of the production line. At the same time, the pushing structure drives the two clamping frames to move towards the main frame in a synchronous manner through the sliding rod and the crossbar, ensuring that the plate can be smoothly and symmetrically connected to the main frame. This reduces assembly stress and misalignment caused by unilateral force or positional deviation, and improves processing accuracy and assembly consistency. In addition, the clamping plate clamps the plate within the clamping frame through the adjusting screw. Together with the positioning cylinder for positioning the main frame and the auxiliary fixing of the clamping structure, they form a stable and reliable double clamping system, effectively preventing the workpiece from loosening or shifting during processing and ensuring welding or assembly quality.

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Example 1 Please see Figure 1-5 As shown, a high-stability motorcycle frame processing and fixing fixture of this embodiment includes a workbench 1, a positioning cylinder 2 and a support frame 14. The positioning cylinder 2 is set on one side of the top of the workbench 1, and the support frame 14 is set on the other side of the top of the workbench 1. The main frame body 3 is set at the center of the inside of the positioning cylinder 2, and a number of clamping structures are set in the inner ring of the positioning cylinder 2. A sliding rod 11 is slidably connected to the top of the support frame 14. A crossbar 10 is connected to one end of the sliding rod 11. Two sliding parts are slidably connected to the outer ring of the crossbar 10. A clamping frame 7 is connected to one side of each sliding part. A positioning structure that can be detachably connected to the top of the crossbar 10 is provided on the top of the sliding part. A clamping plate 15 is provided on one side of the inside of each clamping frame 7. An adjusting screw 18 with one end threaded through the clamping frame 7 is rotatably connected to one side of the clamping plate 15. A plate 4 is provided inside each clamping frame 7. A bracket 6 is connected to one side of the support frame 14. A pushing structure that cooperates with the sliding rod 11 is provided on the top of one side of the bracket 6.

[0023] Workflow: When using this high-stability motorcycle frame to process the fixing fixture, firstly, insert the main frame 3 into the positioning cylinder 2 located on one side of the top of the workbench 1. The inner wall of the positioning cylinder 2 and the outer wall of the main frame 3 are used to achieve initial positioning and axial limitation, ensuring the basic positional stability of the main frame 3 during processing. Then, place the plate 4 to be processed inside the two clamping frames 7, adjusting its position to align with the docking area of ​​the main frame 3. Next, rotate the adjusting screw 18 to push the clamping plate 15 within the clamping frame 7, thereby clamping the side of the plate 4 and achieving a firm fixation. After clamping the plate 4, the operator activates the pushing structure located on the top of one side of the bracket 6. This pushing structure acts on the sliding rod 11, driving the sliding rod 11 to slide along the top of the support frame 14, causing the connected crossbar 10 to move towards the main frame 3. Directional movement; as the crossbar 10 advances, the two sliding parts slidably connected to its outer ring move accordingly, thereby driving the two clamping frames 7 and the clamped plate 4 to move closer to the main frame 3 simultaneously, until the plate 4 and the main frame 3 are docked and fitted together; during the adjustment process, if it is necessary to fine-tune the relative position of the two clamping frames 7 to adapt to the main frame 3 of different widths or layouts, the positioning structure at the top of the sliding part can be loosened first to disconnect it from the crossbar 10, and then the sliding part can be manually slid along the axis of the crossbar 10 to adjust the distance between the two clamping frames 7. After adjusting to the appropriate position, the sliding part can be fixed to the crossbar 10 again through the positioning structure, thereby achieving flexible adaptation of the clamping position; throughout the entire processing process, the clamping structure in the positioning cylinder 2 also plays an auxiliary clamping role for the main frame 3, further improving the overall clamping stability and ensuring the smooth progress of welding or assembly operations.

[0024] Example 2 Please see Figure 1-5 As shown in the figure, a high-stability motorcycle frame processing and fixing fixture of this embodiment includes a clamping structure comprising an abutment plate 9 and an abutment screw 8 rotatably connected to one side of the abutment plate 9. One end of the abutment screw 8 is threaded through the side wall of the positioning cylinder 2. Specifically, through the threaded engagement of the abutment plate 9 and the abutment screw 8 with the side wall of the positioning cylinder 2, after the main frame 3 is inserted into the positioning cylinder 2 for initial positioning, the abutment screw 8 is rotated to drive the abutment plate 9 to move inward and press against the outer wall of the main frame 3, thereby achieving radial clamping and circumferential fixing of the main frame 3. This enhances the positioning stability of the main frame and effectively prevents it from rotating or shifting due to vibration or external force during processing, further improving the reliability of the overall clamping system.

[0025] A handle is fixedly connected to one end of the contact screw 8. The outer ring of the handle has several anti-slip grooves. Specifically, through the fixed connection between the handle and the end of the contact screw 8, and the setting of anti-slip grooves on the outer ring of the handle, the operator can rotate the contact screw 8 by gripping the handle. The anti-slip grooves effectively increase the friction between the hand and the handle, preventing slippage. This achieves the effect of improving the convenience and labor-saving of adjustment operation, making the clamping operation of the main frame 3 more efficient and safe, especially suitable for production environments with frequent clamping.

[0026] Example 3 Please see Figure 1-5 As shown in this embodiment, a high-stability motorcycle frame processing and fixing fixture includes a sliding frame 17 that slides with the outer ring of the crossbar 10. A sleeve 5 is fixedly connected to the top of the support frame 14. The sliding rod 11 is slidably connected to the inside of the sleeve 5. Specifically, through the sliding engagement of the sliding frame 17 with the outer ring of the crossbar 10 and the slidable connection of the sliding rod 11 with the inside of the sleeve 5, the sliding frame 17 can slide freely along the axial direction of the crossbar 10 to adjust the position of the clamping frame 7. At the same time, the sliding rod 11 slides smoothly within the sleeve 5 to ensure the straightness and stability of the crossbar 10 during the advancement process. This achieves the effect of ensuring smooth movement and precise guidance of the clamping frame 7, avoiding docking errors caused by movement jamming or skew, and improving the flexibility and smoothness of the fixture operation.

[0027] The positioning structure includes a positioning screw 16 with one end threaded through the top of the sliding frame 17. The top of the crossbar 10 has several positioning holes 12 that are adapted to the positioning screw 16. Specifically, by having one end of the positioning screw 16 threaded through the top of the sliding frame 17 and adapted to the multiple positioning holes 12 on the top of the crossbar 10, after adjusting the sliding frame 17 to the required position, the positioning screw 16 is screwed into the corresponding positioning hole 12, which realizes the rapid positioning and reliable locking between the sliding frame 17 and the crossbar 10. This achieves the effect of conveniently and accurately adjusting and fixing the horizontal position of the clamping frame 7, meeting the spacing adaptation requirements when different specifications of the plate body 4 are connected to the main frame body 3, and enhancing the versatility and adjustment accuracy of the clamp.

[0028] The bracket 6 is L-shaped. One end of the horizontal section of the bracket 6 is fixedly connected to the side wall of the support frame 14. The pushing structure includes a pushing cylinder 13 installed on one side of the vertical section of the bracket 6. The output end of the pushing cylinder 13 is connected to the end of the sliding rod 11. Specifically, through the fixed connection between the horizontal section of the L-shaped bracket 6 and the side wall of the support frame 14, and the setting of the pushing cylinder 13 installed on one side of the vertical section of the bracket 6 with its output end connected to the end of the sliding rod 11, after the clamping plate 15 is fixed to the plate body 4, the pushing cylinder 13 is activated. Its piston rod extends out to push the sliding rod 11 to slide along the sleeve 5, thereby driving the crossbar 10 and the clamping frames 7 on both sides to move synchronously towards the main frame 3. This achieves the effect of automatic feeding of the clamping components, improving docking efficiency and consistency of action, reducing manual intervention, and improving the automation level and operational safety of the fixture.

[0029] When using this high-stability motorcycle frame machining fixture, the main frame 3 is first inserted into the positioning cylinder 2 located on one side of the top of the workbench 1. The inner wall of the positioning cylinder 2 and the outer wall of the main frame 3 are used to achieve initial positioning and axial limitation. Then, by rotating the abutment screw 8, a handle connected to one end facilitates force application. The anti-slip groove on the outer ring of the handle effectively prevents hand slippage. The abutment screw 8, with its thread penetrating the side wall of the positioning cylinder 2, drives the abutment plate 9 to move inward, causing the abutment plate 9 to tightly abut against the outer wall of the main frame 3. This completes the radial clamping and circumferential fixing of the main frame 3, ensuring that it will not rotate or shift during machining. Simultaneously, the fixture to be machined... The processed plate 4 is placed inside the two clamping frames 7, and its position is adjusted to align with the docking area of ​​the main frame 3. Then, by rotating the adjusting screw 18, one end of it pushes the clamping plate 15 to move within the clamping frame 7, thereby clamping the side of the plate 4 and achieving a firm fixation of the plate 4. If it is necessary to adapt to main frames 3 of different widths or layouts, the positioning screw 16 can be loosened first. One end of the positioning screw 16 is threaded through the top of the sliding frame 17. The sliding frame 17 is part of the sliding component and slides with the outer ring of the crossbar 10. After loosening, the sliding frame 17 can be manually slid along the axis of the crossbar 10, thereby moving the clamping frame 7 to adjust the two clamping frames 7. After adjusting the spacing to a suitable position, the positioning screw 16 is screwed back into the corresponding positions of the positioning holes 12 opened at the top of the crossbar 10, realizing the detachable connection and precise positioning of the sliding frame 17 and the crossbar 10; after completing the clamping and position adjustment of the plate 4, the push cylinder 13 is activated. The push cylinder 13 is installed as a push structure on one side of the vertical section of the L-shaped bracket 6. One end of the horizontal section of the bracket 6 is fixedly connected to the side wall of the support frame 14 to form a stable support structure. The output end of the push cylinder 13 is connected to the sliding rod 11, driving the sliding rod 11 to slide along the inside of the sleeve 5 fixed at the top of the support frame 14. The movement of the sliding rod 11 drives the sliding frame 17 and the crossbar 10 to move together. The crossbar 10 connected to it is pushed towards the main frame 3 as a whole. The two sliding frames 17 on the outer ring of the crossbar 10 move synchronously, thereby driving the two clamping frames 7 and the clamped plate 4 to smoothly approach the main frame 3 until the plate 4 and the main frame 3 are connected and tightly fitted. The entire pushing process maintains straightness and stability under the guidance of the sleeve 5 on the sliding rod 11, avoiding deflection. During the entire processing, the abutting plate 9 and the abutting screw 8 inside the positioning cylinder 2 continuously apply clamping force to the main frame 3. The clamping plate 15 keeps the plate 4 clamped by adjusting the screw 18, and pushes the cylinder 13 to maintain the feed force, ensuring the smooth progress of welding or assembly operations.This high-stability motorcycle frame processing and fixing fixture achieves initial positioning through the cooperation of the positioning cylinder 2 and the main frame 3. Then, the contact screw 8 drives the contact plate 9 to radially clamp the main frame 3. Combined with the design of the handle and anti-slip groove, it improves the ease of operation and labor saving, effectively solving the problem of unstable positioning of the main frame. By adjusting the screw 18, the clamping plate 15 is pushed to clamp the plate 4, realizing the adaptive clamping of plates of different thicknesses. Through the sliding cooperation between the sliding frame 17 and the crossbar 10 and the detachable connection between the positioning screw 16 and the positioning hole 12, the clamping frame 7 can be flexibly adjusted and precisely fixed in the horizontal direction, solving the defect of existing fixtures that cannot adapt to main frames of different sizes, and significantly improving the versatility and flexibility of the fixture. By pushing the cylinder 13 to drive the sliding rod 11 to slide in the sleeve 5, the crossbar 10 and the clamping frame 7 are fed synchronously, realizing automated docking and advancement, improving work efficiency and consistency of action. The L-shaped bracket 6 provides a stable installation base for the pushing cylinder 13, ensuring the reliability of thrust transmission.
