Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing equipment technology, and in particular to an anti-sway stabilization mechanism for a vehicle frame tilting machine. Background Technology

[0002] A car frame flipping machine is used to flip car frames. In a typical car flipping machine, the lifting rope is controlled by a hoisting frame to move, so that it is put into the two ends of the car frame and lifted vertically from above the placement frame. Then, the drive mechanism drives the lifting rope to rotate, so that the car frame rolls and rotates half a turn inside the rope, thus flipping the car frame. Then, the lower rope slowly lowers the flipped car frame and places it on the placement frame.

[0003] In the existing technology of cable-type frame tilting machines, the cable is flexible. After the frame is tilted, it shakes due to the lack of limiting, which prevents it from falling accurately into the placement frame immediately. It is necessary to wait for it to come to a relative stop before it can be controlled to descend stably and be placed. This affects the tilting efficiency of the frame and is not conducive to further improving the frame processing efficiency. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Example 1: Please refer to Figures 1 to 7 :

[0028] This utility model proposes an anti-sway stabilization mechanism for a vehicle frame tilting machine, comprising: a tilting machine frame placement frame 1, adjacent tilting machine frame placement frames 1 are fixedly connected by a stabilizing frame 2, a reversing shaft 3 is rotatably connected through the middle of the stabilizing frame 2, a reversing driven worm gear 301 is fixedly connected to the outside of the reversing shaft 3, a reversing swing rod 302 is fixedly connected to the front end and rear end of the reversing shaft 3 respectively, a reversing motor 4 is fixedly connected to the inner wall of the stabilizing frame 2 by bolts, a reversing worm 401 is fixedly connected to the shaft of the reversing motor 4, the reversing worm 401 is connected to the reversing driven worm gear 301 to form a worm gear transmission, a guide support 5 is fixedly connected to the outer end of the reversing swing rod 302, an adjusting frame 7 is slidably connected to the outside of the guide support 5, and a connecting rod is fixedly connected to the outer end of the adjusting frame 7. The frame guide frame 702 has a vertical clamping rod 8 internally connected to it. A clamping motor 6 is fixedly connected below the guide support 5, and a clamping drive wheel 601 is fixedly connected to the shaft of the clamping motor 6. A frame rack 701 is fixedly connected below the adjusting frame 7, and the frame rack 701 meshes with the clamping drive wheel 601. Under normal conditions, during frame transport or tilting, the reversing swing arm 302, the vertical clamping rod 8, and the stabilizing frame 2 remain parallel and in a retracted state, preventing collisions with the vertical clamping rod 8 during frame movement or tilting, and avoiding space reduction affecting frame movement. After the frame is tilted, if the frame sways during suspension by ropes, the reversing motor 4 can be activated. The reversing motor 4 is connected to the reversing driven worm wheel 301 via the reversing worm gear 401. The worm gear transmission drives the reversing shaft 3 to rotate 90 degrees, causing the reversing swing arm 302 and the vertical clamping rod 8 to swing upwards and perpendicular to the stabilizing frame 2. At this time, the two vertical clamping rods 8 are located at the front and rear of the frame, respectively. The control motor 6 rotates, and through the gear and rack transmission formed by the clamping drive wheel 601 and the connecting frame rack 701, the control frame 7 is retracted towards the middle of the stabilizing frame 2, and the vertical clamping rods 8 are pulled towards the frame, so that the two frame rod pads 803 are in contact with the front and rear edges of the frame, respectively, so that the frame stops swaying. With the lifting device The frame is slowly lowered, and the vertical clamp 8 moves slowly downward with the frame inside the connecting frame guide frame 702 until the frame is stably placed above the tilting machine frame placement frame 1. At this point, the clamping motor 6 starts in reverse, pushing the adjusting connecting frame 7 and the vertical clamp 8 outward, causing the frame rod pad 803 to separate from the frame. The vertical clamp 8 moves upward under the tension of the return spring 802, causing the vertical clamp 8 to automatically return to its original position. After the frame is placed, the reversing motor 4 is controlled to operate, and through a series of transmission mechanisms, the vertical clamp 8 swings 90 degrees to retract.

[0029] Furthermore, a support groove 501 is provided on the side of the guide support 5. The adjusting frame 7 is a rectangular frame structure. The inner edge of the adjusting frame 7 is slidably connected with the support groove 501 to play a guiding role, so that the adjusting frame 7 can move back and forth in the guide support 5.

[0030] Furthermore, a limiting base plate 801 is fixedly connected to the bottom of the vertical clamping rod 8. The limiting base plate 801 is perpendicular to the vertical clamping rod 8. Two reset springs 802 are fixedly connected to the top of the limiting base plate 801. The top of the reset springs 802 is fixedly connected to the lower surface of the adjusting frame 7. When the vertical clamping rod 8 is pushed away from the frame by the adjusting frame 7, the vertical clamping rod 8 moves upward and resets under the tension of the reset springs 802, thus realizing the automatic retraction of the vertical clamping rod 8.

[0031] In Example 2, based on Example 1, the adjusting frame 7 is perpendicular to the front surface of the stabilizing frame 2, and the vertical clamping rod 8 is perpendicular to the adjusting frame 7. A frame rod pad 803 is fixedly connected to the side of the vertical clamping rod 8 facing the center of the stabilizing frame 2. The frame rod pad 803 is made of rubber and its outer surface is covered with a layer of velvet. By setting the frame rod pad 803, the vertical clamping rod 8 can avoid causing wear to the frame when clamping the frame, and also plays a buffering role, reducing the noise generated when the vertical clamping rod 8 touches the frame.

[0032] The working principle of this embodiment is as follows: First, the frame is hoisted and flipped using a lifting device and ropes. When the frame is flipped, the hoisting frame controls the movement of the hoisting ropes, which are then inserted into both ends of the frame and vertically lifted above the frame placement frame 1 of the flipping machine. Then, the drive mechanism drives the hoisting ropes to rotate, causing the frame to roll and rotate half a revolution inside the ropes, thus completing the flipping of the frame. During the transfer or flipping of the frame, the reversing swing arm 302, the vertical clamp 8, and the stabilizing frame 2 remain parallel and in a retracted state, which can prevent the frame from colliding with the vertical clamp 8 during movement or flipping and avoid the reduction of space affecting the movement of the frame. After the frame is flipped, if the frame sways during the suspension process by the ropes, the reversing motor 4 can be started. The reversing motor 4 is connected to the reversing driven worm wheel 301 via the reversing worm gear 401. The worm gear transmission drives the reversing shaft 3 to rotate 90 degrees, causing the reversing swing rod 302 and the vertical clamping rod 8 to swing upwards and perpendicular to the stabilizing frame 2. At this time, the two vertical clamping rods 8 are located at the front and rear of the frame, respectively. The control motor 6 rotates, and through the gear and rack transmission formed by the clamping drive wheel 601 and the connecting frame rack 701, the control frame 7 is retracted towards the middle of the stabilizing frame 2, and the vertical clamping rods 8 are pulled towards the frame, so that the two frame rod pads 803 are in contact with the front and rear edges of the frame, respectively, so that the frame stops swaying. As the lifting device slowly lowers the frame, the vertical clamping rods... 8. Inside the connecting frame guide frame 702, the frame moves slowly downwards until it is stably placed above the tilting machine frame placement frame 1. At this point, the clamping motor 6 starts in reverse, pushing the adjusting connecting frame 7 and the vertical clamping rod 8 outwards, causing the frame rod pad 803 to separate from the frame. The vertical clamping rod 8 moves upwards under the tension of the return spring 802, causing the vertical clamping rod 8 to automatically return to its original position. After the frame is placed, the reversing motor 4 is activated, and through a series of transmission mechanisms, the vertical clamping rod 8 swings ninety degrees, returning to a state parallel to the stable connecting frame 2, thus avoiding affecting the hoisting and movement of the frame.
