Description

Technical Field

[0001] This utility model relates to the field of automobile production technology, specifically a vehicle frame tilting device. Background Technology

[0002] In the field of special vehicle production, the tilting of the chassis is mostly done by using a crane with slings or by using a positioner. After the chassis is tilted, subsequent welding and fixing work can be carried out. When using a crane with slings, the chassis needs to be fixed first, then lifted by the slings and tilted. During use, the slings will wear out, so the machine needs to be stopped and replaced after a short period of use. Therefore, positioners are now mostly used. When using a positioner, the workpiece needs to be locked, the workpiece needs to be loaded and unloaded, and the workpiece needs to be transferred again before subsequent operations can be carried out.

[0003] Existing frame tilting devices require manual fixing of the frame and manual unfixing after tilting, which is inconvenient and cumbersome, resulting in low efficiency. To avoid these technical problems, it is necessary to provide a frame tilting device to overcome the defects of the prior art. Utility Model Content

[0028] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0029] Example: Figure 1-4 As shown, this utility model provides a technical solution, a vehicle frame tilting device, including a fixed frame 1, and a tilting component 2 is installed on the top of the fixed frame 1;

[0030] The flipping assembly 2 includes a fixed base 201, a bearing 202, a rotating rod 203, a mounting base 204, a reducer 205, a servo motor 206, a connecting rod 207, a sliding groove 208, a sliding block 209, a pushing block 210, a fixed groove plate 211, a hydraulic rod 212, and a limiting plate 213;

[0031] A fixed base 201 is installed at the top of the fixed frame 1. A bearing 202 is embedded in the inner side of the fixed base 201. A rotating rod 203 is embedded in the inner side of the bearing 202. A mounting base 204 is welded to one side end face of the fixed frame 1. A reducer 205 is installed at the top of the mounting base 204. The transmission end of the servo motor 206 is connected to the input end of the reducer 205. The input end of the servo motor 206 is electrically connected to the output end of the external power supply to facilitate torque enhancement. The servo motor 206 is installed on one side end face of the reducer 205.

[0032] A connecting rod 207 is sleeved on the outer side of the rotating rod 203. There are two connecting rods 207, which are symmetrically sleeved on the outer side of the rotating rod 203 to facilitate the tilting of the frame. A sliding groove 208 is opened on the inner side of the connecting rod 207. A sliding block 209 is slidably engaged on the inner side of the sliding groove 208. A push block 210 is welded to one end face of the sliding block 209. A fixing groove plate 211 is welded to one end face of the connecting rod 207. A hydraulic rod 212 is installed on the inner side of the fixing groove plate 211. The telescopic ends of the hydraulic rod 212 are welded to the push block 210. The input end of the hydraulic rod 212 is electrically connected to the output end of the external controller, which is conducive to the quick fixation of the frame. A limit plate 213 is welded to the top of the connecting rod 207.

[0033] A buffer assembly 3 is installed on one side of the fixing frame 1;

[0034] The buffer assembly 3 includes a base plate 301, a lifting cylinder 302, a telescopic rod 303, a sliding cylinder 304, a buffer spring 305, and a buffer sliding column 306;

[0035] A lifting cylinder 302 is installed at the top of the base plate 301. A telescopic rod 303 is connected to the telescopic end of the lifting cylinder 302. A sliding cylinder 304 is welded to the top of the telescopic rod 303. A buffer spring 305 is spot-welded to the inner side of the sliding cylinder 304. A buffer sliding column 306 is slidably connected to the inner side of the sliding cylinder 304. The outer diameter of the buffer sliding column 306 is equal to the inner diameter of the sliding cylinder 304. The input end of the lifting cylinder 302 is electrically connected to the output end of an external controller, which is beneficial for quickly moving the frame.

[0036] The working principle and usage process of this utility model are as follows: First, the operator moves the frame to be flipped to the top of the connecting rod 207, and then places the frame on the top of the connecting rod 207. At this time, one end of the frame will be located on one side of the limiting plate 213. Then, the operator controls the four hydraulic rods 212 on both sides to retract simultaneously. Then, the hydraulic rods 212 drive the pushing block 210 to move towards the limiting plate 213. At this time, the pushing block 210 will drive the sliding block 209 to slide at a constant speed inside the sliding groove 208. At this time, the frame can be fixedly clamped between the limiting plate 213 and the pushing block 210 by the hydraulic rods 212, so that the frame can be quickly fixed.

[0037] Next, the servo motor 206 is started, which drives the reducer 205. The reducer 205 then drives the rotating rod 203 to rotate, which in turn drives the connecting rod 207 to rotate and flip. At this point, the frame can be rotated to the top of the buffer sliding column 306. After the frame flips and the buffer sliding column 306 is supported, the hydraulic rod 212 can be extended outward to release the frame's restriction. The hydraulic rod 212 will pull and fix the frame between the limit plate 213 and the push block 210, thus quickly fixing the frame. After flipping, the hydraulic rod 212 can be released again to quickly complete the frame flipping operation. This eliminates the need for workers to repeatedly fix and disassemble the frame, and it is applicable to various frame specifications, further improving processing efficiency.

[0038] Next, when the frame flips to the top of the buffer sliding column 306, the frame will first contact the buffer sliding column 306, which will compress the buffer spring 305. At this time, the buffer spring 305 can buffer the impact force on the frame, thus ensuring that the frame will not be damaged. Subsequently, when the transfer trolley moves to the bottom of the frame, all the lifting cylinders 302 are controlled to retract simultaneously, driving the frame to slowly descend onto the transfer trolley. When the telescopic rod 303 is fully retracted, the transfer trolley can be moved, so that the next stage of processing can be carried out quickly, protecting the integrity of the frame while further ensuring transfer efficiency.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
