Description

Technical Field

[0001] The present invention relates to the technical field of automobile parts production, and specifically relates to a frame grinding tooling. Background Technique

[0002] The frame is a frame structure straddling the front and rear axles of an automobile, commonly known as the crossbeam, which is the base of the automobile. Generally composed of two longitudinal beams and several crossbeams, it is supported on the wheels via suspension devices, the front axle, and the rear axle. In order to improve the processing quality of the automobile frame and the fitting degree when the frame is assembled with other automobile parts, after the frame processing is completed, the outer surface of the frame needs to be ground to remove burrs and other problems generated during production.

[0003] In the prior art, such as the "Electric Vehicle Frame Angle Grinding Tooling" with the Chinese patent application number CN113997146A, it includes a stabilizing member connected to the tooling table for clamping the frame; a grinding member is provided at the frame angle, and the grinding member is inserted into the bending of the frame angle. A pushing component is provided between the two grinding member brackets, and the pushing component is used to drive the grinding member to rotate and insert into the bending of the frame angle. The stabilizing member stabilizes the frame to be ground at the top position of the tooling table, adjusts the grinding member to be at the frame angle position, and under the action of the pushing component, the grinding member is rotated and moved back and forth along the angle at the same time for grinding, so as to facilitate grinding the angles on both sides of the frame at the same time, and it is convenient to grind the frame angle quickly and stably while stabilizing the frame, avoiding the inconvenience of grinding caused by the shaking of the frame during the grinding process.

[0004] However, in the prior art, the frame is generally composed of multiple longitudinal beams and crossbeams. The longitudinal beams are located on the two outer sides of the frame, which is convenient for direct grinding. However, it is difficult to directly position the grinding tooling for the frame in the middle position. When grinding, it is necessary to contact each surface of the crossbeam, resulting in that the surface of the grinding machine cannot be perfectly contacted and fitted with the crossbeam, thus affecting the polishing quality when grinding the crossbeam and reducing the finished product quality of grinding the frame.

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Refer to Figure 1-7 As shown: A vehicle frame grinding tooling includes a driving mechanism 2. A positioning mechanism 4 is arranged above the top end of the driving mechanism 2. Buffer mechanisms 3 are arranged on the outer sides of both ends of the positioning mechanism 4. The buffer mechanism 3 includes a first clamping plate 31 and a second clamping plate 32. The positioning mechanism 4 includes a positioning rail 41. A sliding block 5 is slidably connected to the outer side wall of the positioning rail 41. A grinding machine main body 6 is fixedly connected to the side wall of the sliding block 5. A circular groove is opened at the central position of the side wall of the positioning rail 41. A screw rod 42 is rotatably connected to the positioning rail 41 at the position of the circular groove. The outer side wall of the screw rod 42 is threadedly connected with the sliding block 5. When in use, both buffer mechanisms 3 are fixed between the longitudinal beams on both sides of the vehicle frame. The positioning mechanism 4 is placed above the vehicle frame cross beam to be ground. The orientation of the sliding block 5 during sliding is limited by the positioning rail 41, so that the sliding block 5 drives the grinding machine main body 6 to always align the grinding surface with the grinding surface of the vehicle frame. The position of the sliding block 5 is limited by the screw rod 42, which is convenient for the sliding block 5 to move horizontally and drive the grinding machine main body 6 to grind from one end of the cross beam to the other end;

[0040] A rotating assembly 43 is arranged on one side of the positioning rail 41, and a moving component 44 is arranged on the other side of the positioning rail 41. Control components 45 are arranged on the outer sides of both first clamping plates 31. The control component 45 includes a rotating disk 451 rotatably connected to the side wall of the first clamping plate 31. A rotating column 454 is fixedly connected to the outer side wall of the rotating disk 451. By arranging the control component 45 on the two outer side walls of the positioning mechanism 4, the rotation angle of the positioning rail 41 or the screw rod 42 is controlled by rotating the control component 45, which is convenient for adjusting the orientation of the grinding machine main body 6 and the position of horizontal grinding;

[0041] The rotating assembly 43 includes a first limiting gear ring 431 and a first rotating gear ring 432. The first limiting gear ring 431 is fixedly connected to the side wall of the first clamping plate 31 at the corresponding position. A first rotating seat 433 is rotatably connected to the outer side wall of the first rotating gear ring 432. A fixed connection is provided between the side wall of the first rotating seat 433 and the second clamping plate 32 at the corresponding position. A first rotating circular plate 434 is fixedly connected to the inner side wall of the first rotating gear ring 432. One end of the positioning rail 41 penetrates through the outer side wall of the first rotating circular plate 434 and is fixedly connected to the side wall of the rotating disk 451 at the corresponding position. The rotating assembly 43 is located inside the buffer mechanism 3 on one side. Among them, the first rotating gear ring 432 is fixedly connected to the positioning rail 41 through the first rotating circular plate 434. When it is necessary to adjust the grinding orientation angle of the grinder main body 6, only need to rotate the rotating column 454 on the corresponding side. Drive the rotating disk 451 to rotate through the rotating column 454, so that the rotating disk 451 drives the connected positioning rail 41 to rotate, so that the positioning rail 41 rotates together with the first rotating circular plate 434, so that the positioning rail 41 drives the sliding block 5 to rotate a certain angle, thereby realizing the adjustment function of the grinding surface of the grinder main body 6;

[0042] The moving component 44 includes a second limiting gear ring 441 and a second rotating gear ring 442. The second limiting gear ring 441 is fixedly connected to the side wall of the first clamping plate 31 at the corresponding position. The outer side wall of the second rotating gear ring 442 is rotatably connected with a second rotating seat 443. The side wall of the second rotating seat 443 is fixedly connected to the second clamping plate 32 at the corresponding position. The inner side wall of the second rotating gear ring 442 is fixedly connected with a second rotating circular plate 444. The positioning rail 41 is rotatably connected to the outer side wall of the second rotating circular plate 444. One end of the screw rod 42 penetrates through the outer side wall of the second rotating circular plate 444 and is fixedly connected to the center position of the side wall of the corresponding rotating disk 451. The moving component 44 is located inside the buffer mechanism 3 on the other side. When it is necessary to adjust the sliding position of the slider 5 on the positioning rail 41, only need to rotate the rotating column 454 on the other side, so that the rotating column 454 at this position drives the rotating disk 451 to rotate, so that the rotating disk 451 drives the screw rod 42 to rotate, so that the screw rod 42 rotates relative to the positioning rail 41, so that the screw rod 42 drives the slider 5 to move in a threaded manner. Since the slider 5 is limited by the positioning rail 41, the slider 5 slides on the positioning rail 41, thus realizing the effect of adjusting the grinding horizontal position of the grinder main body 6. After adjusting the grinding angle and horizontal position of the grinder main body 6, the buffer mechanism 3 is respectively clamped and fixed to both sides of the vehicle frame, so that the second clamping plate 32 moves towards the first clamping plate 31, so that the position between the second limiting gear ring 441 and the second rotating gear ring 442 is locked, so that the second rotating gear ring 442 drives the second rotating circular plate 444 to be fixed, so that the second rotating circular plate 444 limits the position of the screw rod 42, preventing the screw rod 42 from sliding again; at the same time, the position between the first limiting gear ring 431 and the first rotating gear ring 432 is also locked, so that the first limiting gear ring 431 fixes the first rotating gear ring 432, preventing the first rotating circular plate 434 from rotating, so that the position of the positioning rail 41 is kept stable, preventing the positioning rail 41 from driving the slider 5 to deflect.

[0043] According to Figure 5 and Figure 7As shown, positioning columns 35 are fixedly connected to the four corner positions of the side wall of the second clamping plate 32. The outer side walls of the positioning columns 35 penetrate through the side wall of the first clamping plate 31 and are fixedly connected to first circular baffles 33. Buffer springs 36 are arranged on the outer side walls of the positioning columns 35. One end of each buffer spring 36 is fixedly connected to the side wall of the first clamping plate 31, and the other end of each buffer spring 36 is fixedly connected to the side wall of the second clamping plate 32. A second circular baffle 452 is fixedly connected to the outer end of the rotating column 454. An anti-slip sleeve 453 is rotatably connected to the outer side wall of the rotating column 454. A sliding plate 34 is fixedly connected to the bottom end of the first clamping plate 31. During use, the two buffer mechanisms 3 are respectively clamped on the cross beams on both sides of the vehicle frame, so that the second clamping plate 32 is squeezed by the vehicle frame, thereby causing the second clamping plate 32 to move towards the first clamping plate 31, causing the buffer springs 36 between the second clamping plate 32 and the first clamping plate 31 to be squeezed, making the second clamping plates 32 on both sides fit more closely with the first clamping plate 31, reducing the problem that the direct squeezing force of the first clamping plate 31 when clamping the vehicle frame causes damage to the vehicle frame. By providing the first circular baffles 33 on the positioning columns 35, the problem that the first clamping plate 31 detaches from the positioning columns 35 is avoided. By providing the anti-slip sleeve 453 on the outer side wall of the rotating column 454, the friction force when the hand holds and rotates the rotating column 454 is increased, facilitating the rotation between the positioning rail 41 and the screw 42.

[0044] According to Figure 1 、 Figure 3 and Figure 4 As shown, the driving mechanism 2 includes a driving plate 21. A moving mechanism 1 is arranged below the bottom end of the driving plate 21. Two cylinders 22 are fixedly connected to the center position of the bottom surface of the driving plate 21. The output ends of the cylinders 22 are fixedly connected to the center position of the side wall of the sliding plate 34. Two slide rails 24 are fixedly connected to the top surface of the driving plate 21. A sliding seat 26 is slidably connected to the outer side wall of each slide rail 24. A connecting plate 25 is fixedly connected to the top surface of the sliding seat 26. When it is necessary to adjust the two buffer mechanisms 3 to clamp and fix the vehicle frame, the two cylinders 22 at the bottom end of the driving plate 21 are started, so that the two cylinders 22 respectively horizontally push the sliding plates 34 on both sides, causing the sliding plates 34 to drive the connecting plate 25 to move horizontally above the driving plate 21, and causing the connecting plate 25 to slide on the slide rails 24 through the sliding seats 26 at the bottom end, thereby causing the sliding plates 34 to drive the first clamping plate 31 to slide in the horizontal direction, so as to adjust the distance between the two buffer mechanisms 3, facilitating the clamping and fixing of the vehicle frame by the two buffer mechanisms 3 and making the grinding machine body 6 more stable when grinding the vehicle frame.

[0045] According to Figure 2 and Figure 3As shown in the figure, a connecting plate 25 is fixedly connected between the side walls of a sliding plate 34. Support plates 23 are arranged on the outer sides of both ends of a slide rail 24. The top surface of the support plate 23 is fixedly connected to the bottom surface of the connecting plate 25, and the side surface of the support plate 23 is fixedly connected to the side surface of the sliding plate 34. Support columns 13 are fixedly connected between the driving plates 21 at the four corner positions on the top surface of a bottom plate 11, and universal wheels 12 are fixedly connected to the four corner positions on the bottom surface of the bottom plate 11. By arranging four universal wheels 12 at the bottom end of the bottom plate 11, it is convenient to move the universal wheels 12 on the ground, improving the portability of the grinding tool during use. By fixedly connecting the support columns 13 at the bottom end of the bottom plate 11, a certain gap is left between the driving plate 21 and the bottom plate 11 through the support columns 13, facilitating the installation of air cylinders 22 at the bottom end of the bottom plate 11, thereby providing a driving force for the position adjustment between the two buffer mechanisms 3.

[0046] Usage method and working principle of this device: During use, the bottom plate 11 is driven to slide by the universal wheels 12, and the bottom plate 11 is adjusted to move under the vehicle frame. The air cylinders 22 on both sides are started, so that the air cylinders 22 drive the two sliding plates 34 to expand outwards, and the two buffer mechanisms 3 are respectively placed on both sides of the vehicle frame;

[0047] A rotating column 454 on one side is rotated. The rotating column 454 drives a rotating disk 451 to rotate, and the rotating disk 451 drives a positioning rail 41 to rotate, realizing the adjustment of the rotation angle of the positioning rail 41, thereby adjusting the grinding surface angle of the grinding machine main body 6 to align with the surface of the vehicle frame for grinding;

[0048] The rotating column 454 on the other side is rotated. The screw rod 42 is driven to rotate through the rotating disk 451, so that the screw rod 42 rotates relative to the positioning rail 41, thereby driving the sliding block 5 to move in a threaded manner. Since the sliding block 5 is limited by the positioning rail 41, the sliding block 5 slides on the positioning rail 41, thereby adjusting the position of the horizontal grinding cross beam of the grinding machine main body 6;

[0049] The air cylinders 22 on both sides are started to drive the sliding plates 34 to move inwards, so that the sliding plates 34 drive the two first clamping plates 31 to clamp inwards, and the first clamping plates 31 are pressed against the second clamping plates 32, so that the positions between the second limiting tooth rings 441 and the second rotating tooth rings 442 are locked, and the positions between the first limiting tooth rings 431 and the first rotating tooth rings 432 are also locked, keeping the position of the grinding machine main body 6 continuously stable and improving the stability of the grinding machine main body 6 for grinding the surface of the vehicle frame.

[0050] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
