Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor belong to the range of protection of the utility model.

[0029] Please refer to Figures 1-6 The utility model provides a technical scheme:

[0030] The utility model provides a kind of automobile parts transfer frame, its core structure includes transfer frame body, universal wheel, support frame and synchronous lifting assembly, each component is realized collaborative operation by mechanical connection, as follows specifically:

[0031] Transfer frame body 1 is rectangular frame structure, is welded by section steel, as overall load bearing base.It is fixedly connected with universal wheel 2 in the bottom four corners, universal wheel 2 has self-locking function, can lock position after transfer in place, avoid sliding.

[0032] The left and right sides of transfer frame body 1 are symmetrically provided with multiple layers of support frame 3 (six layers are provided in the embodiment, and designer can adjust the number of layers according to actual situation), and each layer of support frame 3 is hinged to transfer frame body 1 by rotating shaft, so that support frame 3 can rotate in vertical plane about rotating shaft.Specifically, support frame 3 includes horizontally arranged support plate 6, one end of support plate 6 is connected to transfer frame body 1 by rotating shaft, and the other end is free end;

[0033] The upper surface of support plate 6 is fixedly welded with bent plate 601, bent plate 601 is v-shaped, and the vertical section thereof faces the outside of support plate 6, for limiting automobile parts placed on support plate 6;At the connecting place of support plate 6 and bent plate 601 (i.e. the contact position of parts), buffer block 602 is fixed by adhesive or screw, and buffer block 602 is made of rubber material, for preventing scratching on the surface of parts.

[0034] Synchronous lifting assembly is installed on transfer frame body 1, for driving multiple layers of support frame 3 to be inclined synchronously, and its core structure includes:

[0035] Two lifting rods 401 are vertically and slidably arranged on the left and right sides of transfer frame body 1, and the top end and the bottom end of lifting rod 401 extend to the outside of transfer frame body 1.Each lifting rod 401 is located at the middle segment position in the inside of transfer frame body 1, and is fixedly provided with horizontally arranged fixed block 402 (six fixed blocks 402 are arranged on each lifting rod 401, and the number thereof matches the number of support frame 3) by welding or screw thread connection, and the upper surface of fixed block 402 is provided with slide 403 extending in horizontal direction.

[0036] The free end bottom of the support plate 6 of each layer of support frame 3 (i.e. the side away from the rotating shaft) is vertically welded with a sliding rod 404, which is inserted into the slide 403 of the fixed block 402 and can slide forward and backward along the slide 403. When the lifting rod 401 moves up and down, it drives the fixed block 402 to move up and down synchronously, and the slide 403 of the fixed block 402 pushes the free end of the support plate 6 up and down through the sliding rod 404, which makes the support plate 6 rotate around the rotating shaft due to the other end of the support plate 6 being fixed by the rotating shaft, thereby realizing the tilting action of the support frame 3.

[0037] The power source of the synchronous lifting assembly is a manual jack 405 fixedly installed at the bottom of the transfer frame body 1, and the specific connection mode is as follows:

[0038] The middle and lower parts of the two lifting rods 401 are welded and fixed through the transverse connecting rod 406 to form a rectangular frame structure, which not only enables multiple lifting rods 401 to move up and down synchronously, but also constrains the lifting rods 401 to prevent them from rotating;

[0039] The piston rod of the manual jack 405 is arranged upward, and the top end thereof is connected with the center position of the transverse connecting rod 406 through welding or threading. When the jack is operated, the extension and retraction of the piston rod drives the transverse connecting rod 406 to move up and down as a whole, which in turn drives the fixed block 402 and the support frame 3 to move through the lifting rod 401.

[0040] In order to facilitate operation, a horizontal lever 11 is fixedly connected to the rotating shaft of the jack, and a wear-resistant ring 1101 (such as metal or rubber material) is sleeved on one end of the lever 11. The operator can step on the end of the lever 11 to drive the piston rod of the jack to move up and down, which is labor-saving.

[0041] The support pad 5 and the support vertical rod 9:

[0042] A plurality of rubber support pads 5 are fixed on the top and middle horizontal rods of the transfer frame body 1 through bolts, which are used to provide bottom support when the support frame 3 is placed horizontally. At the same time, support vertical rods 9 are also fixed on the vertical rods on the left and right sides of the transfer frame body 1, and the side wall of the support vertical rod 9 is provided with a buffer block 602. When the support frame 3 is tilted to the maximum angle, the automobile parts come into contact with the buffer pad to limit the excessive tilting of the parts.

[0043] A connecting frame 7 is welded at the front end and the rear end of the transfer frame body 1, and a connecting shaft hole 701 is formed in the side plates of the connecting frame 7. A connecting shaft 701 is arranged in the shaft hole. A traction rod 8 is rotatably connected to one side of the connecting frame 7 through a pin shaft, and the other end of the traction rod 8 is fixed with a connecting ring 801, which can be sleeved on the connecting shaft 701 of the adjacent transfer frame, thereby realizing the series traction of multiple transfer frames.

[0044] The handrail 10 is welded on the rear end vertical rod of the transfer frame body 1, and the horizontal section and the vertical section of the handrail 10 are wrapped with anti-skid pads 1001 (such as silica gel material), so as to facilitate the operator to push or pull the transfer frame.

[0045] Working principle

[0046] When the automobile parts need to be loaded, the piston rod of the manual jack 405 is driven to descend by stepping the lever 11, the lifting rod 401 and the fixed block 402 are driven to descend, the support plate 6 of the support frame 3 is gradually flattened under the cooperation of the sliding rod 404 and the slide 403, at this time, the automobile parts are placed on the support plate 6, and the automobile parts are positioned by the bent plate 601 and the buffer block 602.

[0047] When the automobile parts need to be transferred, the piston rod of the jack is operated to ascend, the fixed block 402 drives the sliding rod 404 to ascend, the free end of the support plate 6 is lifted, the support frame 3 is inclined at a certain angle, the automobile parts are adhered to the bent plate 601 by gravity, and sliding is avoided; after the transfer is completed, the universal wheel 2 is locked, the support frame 3 is flattened again by operating the jack, and the automobile parts can be unloaded.

[0048] The above structure realizes the synchronous lifting and tilting of the support frame 3 by mechanical linkage, and considers the stable transportation and convenient loading and unloading of the automobile parts, and is suitable for the batch transfer scene of the automobile parts such as stamping parts and welded parts in the automobile factory.

[0049] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
