DETAILED DESCRIPTION

[0037] The present invention will be further described in detail below through specific embodiments. The following embodiments are only descriptive and not restrictive, and the protection scope of the present invention cannot be limited by them.

[0038] A vehicle rear floor frame precision positioning trolley, the innovation of which is: comprising a material storage locking unit 1 and a transfer trolley unit 3 rollingly mounted on the material storage locking unit through casters 2, the transfer trolley unit being locked by the material storage locking unit;

[0039] The material storage locking unit includes a base plate 14 and caster guide frames 15 installed on both sides of the base plate. The base plate is fixed by anchor bolts 4. Frames 13 are arranged at both ends of the base plate surface. A cylinder 9 is arranged on the frame on one side. The end of the cylinder pressure arm 8 of the cylinder is connected to a pressure block 7. A proximity switch 12 and a bus module 10 are arranged at the rear end of the material storage locking unit. The bus module is connected to the proximity switch and the in-place sensor of the cylinder by cables.

[0040] The transfer vehicle unit includes a base 20 and casters arranged at the four corners of the base, four column mounting plates 19 are installed at intervals on both sides of the base, columns 16 are installed on the column mounting plates, and a precision positioning connecting rod mechanism is installed on the column, and a locking block 22 is arranged in the middle of the base corresponding to the cylinder;

[0041] The transfer trolley unit of the utility model is slidably installed on the material warehouse locking unit through the casters arranged at the bottom. After the transfer trolley unit is in place, the cylinder-driven pressing block on the material warehouse locking unit cooperates with the locking block on the transfer trolley unit to realize the locking and positioning of the transfer trolley unit. After locking, the rear floor frame components of the automobile are placed into the precise positioning connecting rod mechanism of the transfer trolley unit through an external manipulator. After the placement is completed, the material warehouse locking unit releases the lock of the transfer trolley unit, and the transfer trolley unit is pushed out of the material warehouse locking unit, thereby completing the precise positioning and feeding of the rear floor frame of the automobile.

[0042] The precise positioning link mechanism comprises three fork limit blocks 28 which are arranged on the column at intervals from bottom to top, a fork 29 is rotatably installed above the fork limit blocks, the three forks are hingedly connected to the column, the lower fork and the middle fork, and the middle fork and the upper fork are hingedly connected by the first connecting rod 27 and the second connecting rod 25 respectively, and the top of the first connecting rod and the second connecting rod are provided with sliding grooves 26. The structural design is ingenious, and can realize the precise feeding and placement of the multi-layer middle and rear floor frame.

[0043] Affected by the center of gravity of the fork, when the transfer vehicle unit is not loaded with objects, the bottom limit block limits the fork to stay still at a certain angle, while the upper fork is affected by the center of gravity and the connecting rod mechanism, and the fork does not extend out of the column. When the object descends along the guide and contacts the bottom fork, the material drives the bottom fork to rotate, and stops at the position on the other side of the limit. The connecting rod mechanism drives the second-to-last fork to rotate. When the second material falls from above, it stops at the second-to-last fork, driving the third-to-last fork to rotate, and so on. Conversely, after the goods are unloaded, the fork returns to a free state.

[0044] Several groups of guide wheel assemblies are arranged at intervals at both ends of the frame, and the guide wheel assemblies include a first guide bracket 32 ​​and a second guide bracket 311. The first guide bracket is provided with a first guide wheel 33 in a vertical direction, and the second guide bracket is provided with a second guide wheel 30 in a horizontal direction, so as to form a fine guide for the transfer trolley unit and complete the efficient and precise sliding of the transfer trolley unit on the material storage locking unit.

[0046] A limiting block 11 is provided at the rear end of the frame, which can play a limiting role when the material cart transfer unit slides into place, preventing the material cart transfer unit from sliding out and affecting the locking positioning.

[0047] A photoelectric sensor bracket is arranged on the outside of the caster guide frame, and a photoelectric sensor 6 is installed on the photoelectric sensor bracket, which can accurately detect whether the middle and rear floor frame is installed on the transfer cart unit. When the photoelectric sensors on both sides sense signals from each other, it means that there are vacancies on the precise positioning connecting rod mechanism of the transfer cart unit and no parts are installed.

[0048] Inclined guide surfaces 5 are provided at the front and rear bottom surfaces of the base to facilitate the precise matching of the transfer vehicle unit and the guide wheel assembly and ensure the guiding effect.

[0049] The front end of the caster guide frame is an outward-facing figure-eight structure 24, which facilitates the casters of the transfer vehicle unit to smoothly and quickly enter the caster guide frame of the material storage locking unit.

[0050] A handrail 21 is provided at the rear end of the base to facilitate the staff to push or pull the transfer vehicle unit.

[0051] An anti-collision block 23 is arranged at the front end of the base, which prevents the transfer vehicle unit from colliding and being damaged with the material storage locking unit when the transfer vehicle unit slides into place on the material storage locking unit.

[0052] The automobile middle and rear floor frame products of the utility model are placed in the transfer trolley units in sequence by the slings, the transfer trolley units are transported manually to the working position of the material warehouse locking unit, and the transfer trolley units are switched and introduced between the material warehouse locking units to meet the production requirements.

[0053] Although the embodiments and drawings of the present invention are disclosed for illustrative purposes, those skilled in the art will appreciate that various substitutions, changes and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
