DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.
[0023] Referring to Figures 1-5 A gearbox assembly tray device, comprising a support frame 1, the support frame 1 is provided with a lifting assembly, and the upper end of the lifting assembly is fixedly connected with a tray assembly;
[0024] The bottom of the support frame 1 is provided with a plurality of universal wheels with locking function, which is a commonly used part in the existing industry, used in the bottom of various movable tooling or tools to realize the portable function.
[0025] The lifting assembly comprises an electric hydraulic rod 16 fixedly connected with the support frame 1, both ends of the electric hydraulic rod 16 are fixedly connected with the support frame 1 and the connecting plate 2 respectively, the lower surface of the connecting plate 2 is further fixedly connected with a limiting rod 17, and the limiting rod 17 is slidingly connected with the support frame 1.
[0026] In this design, the support frame 1 has four support legs, the electric hydraulic rod 16 is provided with one, and the limiting rod 17 is provided with three. The electric hydraulic rod 16 is used to drive the tray assembly to move up and down, and is used in cooperation with the support frame 1 with universal wheels. When the user assembles the gearbox, first hoist the gearbox and place it on the tray assembly, then move the support frame 1 under the automobile frame, and then control the electric hydraulic rod 16 to elongate to drive the gearbox to move into the frame.
[0027] The tray assembly comprises a connecting plate 2 fixedly connected with the lifting assembly, the connecting plate 2 is fixedly connected with a disc 3, the disc 3 is fixedly connected with a limiting ring 4, the disc 3 is slidingly connected with an inner plate 5, the upper surface of the inner plate 5 is fixedly connected with a support plate 6, the middle part of the disc 3 is provided with a gap, and the lower surface of the inner plate 5 close to the gap is provided with a friction groove 7, wherein the friction groove 7 is a sunken groove, the inner wall of the upper end of the sunken groove is provided with a plurality of protrusions, and the support frame 1 is further fixedly connected with a limiting assembly.
[0028] In this design, the upper surface of the disc 3 and the lower surface of the inner plate 5 are both high-precision polished steel plates, and the upper surface of the disc 3 is coated with lubricating oil, so the friction between them is small. The limiting ring 4 limits the sliding range of the inner plate 5. The friction groove 7 is located at the center of the inner plate 5, and the limiting assembly penetrates the gap and is arranged against the friction groove 7;
[0029] After the staff moves the frame to the appropriate position, the transmission is lifted to the appropriate height using the lifting assembly. Although the position of the transmission can be installed in this state, the bolt hole needs to be completely aligned when the transmission support and other components are fixed to the transmission and the transmission and the automobile engine. At this time, the staff can control the limiting assembly to separate from the friction groove 7, then slightly push the transmission to make it move slightly, or use a crowbar or other tool to insert into the bolt hole, then twist the transmission to align the mounting hole on the transmission with the hole on the fastener or connecting piece. At this time, the inner plate 5 slides on the disc 3, which can make the transmission move slightly to meet the staff's demand for fine adjustment of the transmission position. It should be noted that the transmission of a light car generally weighs about 50 to 80 kilograms. Under dynamic friction, according to experimental data, the dynamic friction coefficient is about 0.15 without lubrication, and the dynamic friction coefficient will decrease significantly to between 0.05 and 0.1 with lubrication. Even if the friction coefficient is 0.1 and the weight is 80 kilograms, the force required to move the transmission slightly is only 78N, which can be easily completed by the staff, and the adjustment range is only used for the bolt hole of the transmission, and the moving distance is small. This design does not need to control the movement of the entire support frame 1, can achieve more precise adjustment of the transmission position, and avoid the transmission from colliding with other parts in the car frame, making the car assembly operation more convenient.
[0030] Further, the limiting assembly includes a sliding sleeve 8 fixedly connected to the connecting plate 2, the upper end of the sliding sleeve 8 is slidingly connected to a limiting block 9, the lower end of the limiting block 9 is fixedly connected to a compression spring 10, the lower end of the compression spring 10 is fixedly connected to the inner wall of the sliding sleeve 8, the lower end of the limiting block 9 is also fixedly connected to a pull rod 11, the support frame 1 is rotatably connected to a foot pedal 14 through a spring shaft, the upper end of the foot pedal is rotatably connected to a connecting rod 12, the upper end of the connecting rod 12 is rotatably connected to a driving rod 13 for moving the connecting rod 12, the support frame 1 is also fixedly connected to a sliding rail, the track of the sliding rail includes a vertical part and an inclined part, and the driving rod 13 is slidingly connected to the sliding rail.
[0031] In this design, the limiting block 9 is used to cooperate with the friction groove 7. After the compression spring 10 drives the limiting block 9 to abut against the friction groove 7, the inner plate 5 is difficult to slide on the disc 3, which greatly increases the resistance to the movement of the gearbox, thereby achieving the purpose of limiting the gearbox. During the assembly process, the operator can step on the foot pedal 14. The foot pedal 14 drives the connecting rod 12 to rotate and move downward, which in turn drives the drive rod 13 to slide along the slide rail. When the drive rod 13 moves along the slide rail, it first slides along the slide rail towards the pull rod 11. After abutting against the pull rod 11, it moves downward and drives the drive rod 13 to move downward. The pull rod 11 then drives the limiting block 9 to overcome the elastic force of the compression spring 10 and move downward, separating from the friction groove 7. In this way, the operator can slide the gearbox to adjust its position. The foot pedal 14 control method can free the operator's hands, making the assembly operation of the gearbox more convenient, improving work efficiency, and reducing the difficulty of operation.
[0032] More specifically, the side walls of the pull rod 11 and the drive rod 13 that are close to each other are fixedly connected with multiple locking teeth 15;
[0033] The locking teeth 15 ensure that after the pull rod 11 abuts against the drive rod 13, the pull rod 11 can stably move downward.
[0034] Furthermore, an inner ring is fixedly connected to the inner wall of the disc 3 near the clearance opening, and a chamfer is provided on the inner wall of the friction groove 7 near the inner ring.
[0035] Setting an inner ring prevents lubricating oil on the disc 3 from dripping down along the relief opening, while setting a chamfer allows lubricating oil to be easily pushed by the sliding of the inner plate 5 along the disc 3, thus preventing the lubricating oil from overflowing the inner ring and dripping down.
[0036] Furthermore, the inner wall of the support frame 1 is fixedly connected with symmetrically arranged placement trays 18;
[0037] The placement tray 18 is used to place assembly tools and fasteners, making it convenient for workers to perform assembly operations.
[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
