Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle assembly, and particularly relates to a rear axle assembly system for special-purpose industrial vehicles in the yard, and a working method of the rear axle assembly system for special-purpose industrial vehicles in the yard. Background Art

[0002] A sightseeing vehicle is also called a special-purpose industrial vehicle in the yard. The assembly of its rear axle is a very crucial link in the vehicle manufacturing process, which involves the process of correctly installing the rear axle assembly onto the vehicle frame. This process requires precise and meticulous operations to ensure the driving performance, stability, and safety of the vehicle.

[0003] Currently, on the rear axle assembly line, the form of automobile rear axle assembly is as follows: directly stack the rear axles on a mobile shelf, and then place the mobile shelf at the working site for installation. The "lifting and moving" method requires frequently lifting, moving, and lowering heavy objects, which is very inconvenient to use. Summary of the Invention

[0004] In view of the problems in the prior art, the present invention proposes the following technical solutions:

[0005] A rear axle assembly system for special-purpose industrial vehicles in the yard, comprising:

[0006] Tool boxes, the number of the tool boxes is multiple, and the tool boxes are used for carrying rear axle parts;

[0007] A line body base frame, on the top of the line body base frame, there are multiple groups of gravity conveyors for moving the tool boxes, and one group of gravity conveyors is located at the blanking position;

[0008] A receiving component, which is used to remove the tool box at the blanking position. The receiving component includes a lifting frame that reciprocates vertically. Deflection plates fixedly connected to the corresponding gravity conveyors are rotatably inserted on both sides of the lifting frame. The lifting frame drives the deflection plates to move the tool box on the corresponding gravity conveyor down into the line body base frame, and then the deflection plates drive the gravity conveyors to rotate to drop the tool box.

[0009] As a preference of the above technical solution, the receiving component further includes a driving part. When the lifting frame drives the deflection plates to move down, the driving part restricts the deflection plates to move vertically. Until the top of the tool box leaves the position of the line body base frame, the driving part rotates the deflection plates to flip the gravity conveyors to drop the tool box.

[0010] As a preference of the above technical solution, the driving part includes a limit block and a mounting plate. A track groove for restricting the movement of the limit block is provided in the middle of the mounting plate. One end of the limit block is provided with a gear fixedly connected to the deflection plate, and a rack meshing with the gear is provided at the bottom of the mounting plate.

[0011] Preferably, one end of the track groove is provided with a stepped expansion. After the gear meshes with the rack, the limiting block is located at the stepped expansion position of the track groove.

[0012] Preferably, support frames are arranged at both ends of the deflection plate. An elevation member for elevating the support frame is arranged inside the deflection plate. The elevation member includes a lead screw and a push rod. An adjustment groove matching the push rod is arranged on the surface of the mounting plate. After the push rod contacts the bottom of the adjustment groove and is pushed to deflect, the gear meshes with the rack. Reverse threads are provided at both ends of the lead screw. Sliders are arranged on the thread surfaces at both ends of the lead screw. One end of each slider is provided with a connection block fixedly connected to the support frame.

[0013] Preferably, the fitting portions between the sliders and the connection blocks are all arranged in a slope shape, and the tops of the connection blocks are arranged in a convex shape.

[0014] Preferably, a plurality of support rollers are rotatably inserted into the support frame, and the tops of the support rollers protrude above the top of the support frame.

[0015] Preferably, the tooling plate is arranged in a double layer, and positioning blocks for placing the rear axle are arranged on the top of the tooling plate.

[0016] The working method of the rear axle assembly system for special industrial vehicles in the factory includes the following steps.

[0017] S1. Loading of rear axle parts: The external feeding device places the tooling plate with rear axle parts on the gravity conveyor of the line base frame, and uses the push during the loading of the tooling plate to provide power for the front tooling plate.

[0018] S2. Assembly of rear axle parts: The external assembly device removes the rear axle parts at the assembly position and installs them on the vehicle, and the tooling plate continues to move into the gravity conveyor at the unloading position.

[0019] S3. Collection of tooling plate: The lifting frame moves downward to drive the deflection plate, so that the tooling box on the corresponding gravity conveyor moves downward, and the driving member restricts the deflection plate to move vertically until the top of the tooling box leaves the position of the line base frame.

[0020] S4. Recycling of tooling plate: Then, the driving member rotates the deflection plate to flip the gravity conveyor to drop the tooling box, and recycles the tooling plate for reuse. Subsequently, the lifting frame moves upward to automatically reset the deflection plate by the driving member until it returns to the original position for the next collection operation.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. The provided flow bar can enable items to slide automatically to the next workstation by utilizing gravity or slight mechanical power, reducing the time and effort of manual handling. When used in conjunction with the work bin, it can effectively utilize vertical and horizontal spaces, further reducing space occupancy, thus significantly improving the overall efficiency of the production line. Additionally, the provided receiving component can move the work bin in the vertical direction. By using the driving component, the deflecting plate can be pushed to deflect after moving for a specific time, thereby flipping the flow bar supporting the tooling plate so that it automatically falls under the action of gravity, eliminating the need to specifically set up a material taking structure to remove the tooling plate and avoiding occupying the usage space of the assembly equipment;

[0023] 2. Utilizing the downward movement of the deflecting plate to provide power for the lifting component, the support frame can be lifted out before the deflecting plate drives the flow bar to deflect, enabling the support rollers to contact the bottom of the tooling plate instead of the flow bar. Thus, during the falling process of the tooling plate, it can be supported, preventing unnecessary friction and scratching, reducing damage to the surface of the flow bar, and avoiding an increase in resistance when the item slides on it, which may affect the smooth material transfer efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments and the drawings of the specification.

[0030] Embodiment

[0031] Figures 1 - 3 In the [embodiment], the rear axle assembly system for special industrial vehicles in the factory area includes:

[0032] The tooling box 10, the number of the tooling boxes 10 is multiple, and the tooling box 10 is used to carry the rear axle parts;

[0033] The line base frame 20, a plurality of sets of flow bars 30 for moving the tooling box 10 are arranged on the top of the line base frame 20, and one set of flow bars 30 is located at the blanking position;

[0034] The receiving component is used to remove the tooling box 10 at the blanking position. The receiving component includes a lifting frame 40 that reciprocates in the vertical direction. Deflection plates 50 fixedly connected to the corresponding flow bars 30 are rotatably inserted on both sides of the lifting frame 40. The lifting frame 40 drives the deflection plates 50 to move the tooling box 10 on the corresponding flow bars 30 downward into the line base frame 20, and then the deflection plates 50 drive the flow bars 30 to rotate to drop the tooling box 10.

[0035] The external feeding device places the tooling plate with the rear axle parts on the flow bars 30 of the line base frame 20, and uses the push during the feeding of the tooling plate to provide power for the front tooling plate. The tooling plates are stacked in sequence and move to the assembly position. Then the external assembly device removes the rear axle parts at the assembly position and installs them on the vehicle. The tooling plate that has completed the part taking continues to move into the flow bars 30 at the blanking position. The lifting frame 40 moves downward to drive the deflection plates 50 to move the tooling box 10 on the corresponding flow bars 30 downward into the line base frame 20, and then the deflection plates 50 drive the flow bars 30 to rotate to drop the tooling box 10.

[0036] The arranged flow bars 30 can make the items slide automatically to the next workstation by gravity or slight mechanical power, reducing the time and energy of manual handling. With the use of the tooling box 10, the vertical and horizontal spaces can be effectively utilized, further reducing the space occupation, thereby significantly improving the overall efficiency of the production line.

[0037] The working method of the rear axle assembly system for the special industrial motor vehicles in the factory includes the following steps,

[0038] S1. Feeding of the rear axle parts: The external feeding device places the tooling plate with the rear axle parts on the flow bars 30 of the line base frame 20, and uses the push during the feeding of the tooling plate to provide power for the front tooling plate;

[0039] S2. Assembly of the rear axle parts: The external assembly device removes the rear axle parts at the assembly position and installs them on the vehicle, and the tooling plate continues to move into the flow bars 30 at the blanking position;

[0040] S3. Collection of the tooling plate: The lifting frame 40 moves downward to drive the deflection plates 50 to move the tooling box 10 downward, and the driving part 60 restricts the deflection plates 50 to move vertically until the top of the tooling box 10 leaves the position of the line base frame 20;

[0041] S4. Tooling plate recovery: the driving member 60 then rotates the deflection plate 50 to flip the flow strip 30 and drop the tooling box 10, and the tooling plate is recovered for reuse. Then the lifting frame 40 moves up so that the driving member 60 automatically resets the deflection plate 50 until it returns to its original position to wait for the next collection work.

[0042] Figures 1 - 4 In the embodiment, the collecting assembly also includes a driving member 60, which limits the deflection plate 50 to move vertically when the lifting frame 40 drives the deflection plate 50 to move downward, until the top of the tooling box 10 leaves the position of the line body base frame 20, and then rotates the deflection plate 50 to make the flow strip 30 flip over and drop the tooling box 10.

[0043] The driving member 60 includes a limit block 61 and a mounting plate 62. A track groove 621 is provided in the middle of the mounting plate 62 for limiting the movement of the limit block 61. A gear 64 fixedly connected to the deflection plate 50 is provided at one end of the limit block 61. A rack 65 meshing with the gear 64 is provided at the bottom of the mounting plate 62.

[0044] One end of the track groove 621 is arranged to be extended in a stepped manner. After the gear 64 is meshed with the rack 65 , the limit block 61 is located at the stepped extended position of the track groove 621 .

[0045] When the tooling plates are collected, the lifting frame 40 moves downward to drive the deflection plate 50 so that the tooling box 10 on the corresponding smooth bar 30 moves downward, and the driving member 60 will limit the deflection plate 50 to make it move vertically until the top of the tooling box 10 leaves the position of the line body base frame 20. During this process, the limit block 61 moves at the upper end of the track groove 621. When the gear 64 engages with the rack 65, the limit block 61 is located at the stepped expansion position of the track groove 621 and is free from the restriction of the track groove 621. When the lifting frame 40 continues to move downward, the gear 64 rotates on the surface of the rack 65 to deflect the deflection plate 50 90 degrees, and the smooth bar 30 flips over to drop the tooling box 10.

[0046] The drive member 60 is configured to push the deflection plate 50 to deflect after it has moved for a specific period of time, thereby flipping the smooth strip 30 supporting the tooling plate so that it automatically falls under the action of gravity. There is no need to specially configure a material-removing structure to remove the tooling plate, thereby avoiding occupying the use space of the assembly equipment.

[0047] Figures 3 - 4Among them, support frames 70 are provided at both ends of the deflection plate 50. An elevation member 80 for elevating the support frames 70 is provided inside the deflection plate 50. The elevation member 80 includes a lead screw 81 and a push rod 82. An adjustment groove 622 matching the push rod 82 is provided on the surface of the mounting plate 62. After the push rod 82 contacts the bottom of the adjustment groove 622 and is pushed to deflect, the gear 64 meshes with the rack 65. Opposite threads are provided at both ends of the lead screw 81. Sliders 83 are provided on the thread surfaces at both ends of the lead screw 81. A connecting block 84 fixedly connected to the support frame 70 is provided at one end of each slider 83.

[0048] The mating surfaces between the sliders 83 and the connecting blocks 84 are all provided in a slope shape, and the tops of the connecting blocks 84 are provided in a convex shape.

[0049] A plurality of support rollers 71 are rotatably inserted into the support frame 70, and the tops of the support rollers 71 protrude above the top of the support frame 70.

[0050] When the tooling plate is collected, the lifting frame 40 moves downward to drive the deflection plate 50, causing the tooling box 10 on the corresponding flow bar 30 to move downward. Due to the downward movement of the deflection plate 50, the push rod 82 contacts the bottom of the adjustment groove 622 and is pushed to rotate. Since opposite threads are provided at both ends of the lead screw 81, and the mating surfaces between the sliders 83 and the connecting blocks 84 are all provided in a slope shape, when the lead screw 81 rotates, the two sliders 83 move in opposite directions to push up the connecting block 84, and the support frame 70 moves upward accordingly, causing the support rollers 71 to contact the bottom of the tooling plate instead of the flow bar 30. When the deflection plate 50 drives the flow bar 30 to deflect, both ends of the tooling plate slide off through the support rollers 71, reducing the friction with the flow bar 30 to avoid damage to the flow bar 30.

[0051] Utilizing the downward movement of the deflection plate 50 to provide power for the elevation member 80 can lift the support frame 70 out before the deflection plate 50 drives the flow bar 30 to deflect, enabling the support rollers 71 to contact the bottom of the tooling plate instead of the flow bar 30, thereby supporting the tooling plate during its downward movement, preventing unnecessary friction and scratches, reducing damage to the surface of the flow bar 30, and avoiding an increase in the resistance when an object slides on it, which affects the smooth transmission efficiency of the material.

[0052] Figure 1 Among them, the tooling plate is provided in a double-layer structure, and a positioning block for placing the rear axle is provided on the top of the tooling plate.

[0053] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
