[0001] This application relates to the technical field of automated storage devices for industrial production, and in particular to a multi-layer heavy-duty automotive parts clamping library. Background Technology
[0002] In current automotive manufacturing production lines, with the increasing market demand for product diversification, multi-model co-production has become a mainstream trend. Different models require different specialized fixtures in processes such as welding and assembly. Therefore, the rapid switching and efficient storage of heavy-duty fixtures have become key aspects for improving production line efficiency and flexibility.
[0003] Traditional fixture storage and changeover solutions primarily employ single-layer fixture warehouse layouts or manual handling combined with overhead crane hoisting. However, with the continuous increase in the number of models produced on the same production line, the drawbacks of single-layer fixture warehouse layouts have become increasingly apparent. Single-layer fixture warehouses significantly increase the floor space required, leading to low workshop space utilization and wasting valuable production space resources. Manual handling is not only labor-intensive and poses safety risks, but its changeover efficiency also cannot meet the demands of modern high-paced production lines, severely impacting the overall efficiency of automobile production.

[0006] Optionally, the traction lifting assembly includes a winding wheel rotatably mounted on the side wall of the gantry, a servo motor for driving the winding wheel to rotate, a traction steel cable wound on the winding wheel, and a transmission wheel rotatably mounted on the top of the gantry; the traction steel cable passes around the transmission wheel and is fixedly connected to the lifting platform.
[0007] Optionally, linear guide rails are fixedly installed on the columns on both sides of the gantry frame, and the linear guide rails on both sides are installed in the vertical direction. Heavy-duty sliders that slide with the linear guide rails are respectively installed on both sides of the lifting platform.
[0008] Optionally, a load-bearing caliper is rotatably mounted on the heavy-duty slider, and a rotary drive component is provided on the heavy-duty slider to drive the load-bearing caliper to deflect. A limit stop is also fixedly mounted on the heavy-duty slider to limit the deflection angle of the load-bearing caliper. A load-bearing socket for inserting the load-bearing caliper is provided on the linear guide rail and at the location of each layer of clamp storage.
[0009] Optionally, the rotary drive includes a telescopic cylinder fixedly mounted on the heavy-duty slider and a connecting rod hinged to the piston rod of the telescopic cylinder, the connecting rod being hinged to the load-bearing caliper.
[0010] Optionally, the heavy-duty slider is further provided with an elastic drive element for driving the load-bearing caliper to deflect toward the linear guide rail.

[0012] Optionally, the fixture receiving tooling includes a support base fixedly installed in the fixture storage area, a lifting platform vertically slidably installed on the support base, and a hydraulic jack installed on the support base for driving the lifting platform to move up and down. There are two lifting platforms, which are symmetrically arranged on both sides of the support base.
[0013] Optionally, a floating support plate is also provided on the support base and located between the two lifting platforms, and an elastic buffer assembly for supporting the floating support plate is also provided on the support base.
[0014] Optionally, the top of the floating support plate is also fixedly provided with a plurality of positioning pins, which are used to be inserted into the positioning holes at the bottom of the heavy-duty fixture.
[0015] In summary, this application includes at least one of the following beneficial technical effects: 1. This application effectively reduces the space occupancy rate required for storing heavy-duty fixtures, while achieving efficient storage and rapid switching between different heavy-duty fixtures, thereby improving the overall efficiency of automobile production. Specifically, the multi-layer storage frame improves workshop space utilization by setting up multiple fixture storage locations, with multiple fixture storage areas in each storage location. The fork arm assembly can receive heavy-duty fixtures and, in conjunction with the traction lifting assembly, drive the lifting platform to move up and down on the gantry, realizing the transport of heavy-duty fixtures to different layers. At the same time, the fork arm assembly can also transport heavy-duty fixtures to the corresponding fixture storage area or remove them from the fixture storage area. The fixture receiving tooling can receive the fixtures transported by the fork arm assembly, facilitating the rapid detachment of heavy-duty fixtures from the fork arm assembly for storage. It can also quickly place and transfer heavy-duty fixtures stored in the fixture storage area onto the fork arm assembly, thereby achieving efficient storage and rapid switching of heavy-duty fixtures, and thus improving the overall efficiency of automobile production.
[0016] 2. This application improves the stability of the lifting platform during vertical lifting by installing vertical linear guide rails on the gantry columns and heavy-duty sliders on both sides of the lifting platform. The cooperation between the linear guide rails and the heavy-duty sliders enhances the stability of the lifting platform during vertical lifting. Simultaneously, by installing rotatable load-bearing clamps on the heavy-duty sliders and load-bearing sockets on the linear guide rails for the clamps to insert into, when the lifting platform reaches the target floor, the telescopic cylinder drives the load-bearing clamps into the corresponding load-bearing sockets via a connecting rod. At this point, the enormous weight of the lifting platform and the heavy-duty clamps is transferred from the traction cable to the rigid columns of the gantry, effectively preventing elastic tension in the cable due to prolonged suspension and stress, and completely eliminating platform swaying during the telescopic movement of the fork arm to pick up and place the clamps.
[0017] 3. This application incorporates a floating support plate with an elastic buffer component on the support base. When the heavy-duty clamp finally settles, the elastic buffer component effectively absorbs the enormous impact force generated by the clamp's descent, protecting the clamp body and the mechanical structure of the multi-layered warehouse frame from impact damage. Simultaneously, the positioning pin at the top of the floating support plate engages with the positioning hole at the bottom of the heavy-duty clamp, ensuring the stability of the clamp during storage in the warehouse. Furthermore, it guarantees the positioning accuracy of the heavy-duty clamp during storage, ensuring precise alignment with the forklift assembly during the next part retrieval.

[0020] The following will be combined with the appendix Figure 1 -Appendix Figure 4 The technical solutions in the embodiments of the present invention are clearly and completely described herein. The described embodiments are merely possible technical implementations of the present invention and not all possible implementations. Those skilled in the art can, in conjunction with the embodiments of the present invention, obtain other embodiments without creative effort, and these embodiments are also within the protection scope of the present invention.
[0021] This application mainly adopts a multi-layer storage structure combined with a lifting and conveying structure to store heavy-duty clamps, which reduces space occupancy and achieves efficient storage and rapid switching of heavy-duty clamps. The following is a further detailed description of this application.
[0022] This application discloses a multi-layer heavy-duty automotive parts fixture library. (Refer to...) Figure 1 The system includes a multi-layer warehouse frame 1, a gantry crane 2, a lifting platform 3, a traction lifting assembly 4, a fork arm assembly 5, and a fixture receiving fixture 6. The multi-layer warehouse frame 1 has multiple fixture storage locations 11 arranged from bottom to top, with at least two fixture storage areas within each location 11. The gantry crane 2 is fixedly mounted at the front end of the multi-layer warehouse frame 1. The lifting platform 3 slides vertically on the gantry crane 2. The traction lifting assembly 4 is mounted on the gantry crane 2 and drives the lifting platform 3 to move up and down. The fork arm assembly 5 is mounted on the lifting platform 3 and is used to receive heavy-duty fixtures and transport them to the corresponding fixture storage area on the multi-layer warehouse frame 1, or to remove heavy-duty fixtures from the storage area. The fixture receiving fixture 6 is located within the storage area and is used to receive fixtures transported by the fork arm assembly 5. This structural configuration reduces the space required for storing heavy-duty fixtures, enables efficient storage and rapid switching between different heavy-duty fixtures, and improves production efficiency.
[0023] Specifically, the multi-layered storage frame 1 is typically welded from high-strength steel, providing excellent stability and load-bearing capacity. The choice of steel can be determined based on actual load-bearing requirements; for example, commonly used carbon steel offers high strength and relatively low cost. The fixture storage area can be an open frame structure or a closed structure with protective railings to adapt to different usage needs. An open frame structure facilitates the storage and retrieval of fixtures, while a closed structure better protects the fixtures from external environmental influences. The layout of the fixture storage area can be rationally planned according to the size and shape of heavy-duty fixtures to improve space utilization.
[0024] Specifically, the gantry frame 2 generally consists of uprights and crossbeams, which can be fixed together by welding or bolting. The uprights are usually made of square steel pipes, which have high strength and stability. The height and span of the gantry frame 2 are determined according to the dimensions of the multi-layer warehouse frame 1 and the actual usage requirements, and its function is to provide a stable support foundation for the lifting platform 3.
[0025] Reference Figure 1 and Figure 2 The lifting platform 3 is generally welded from steel plates, possessing sufficient strength and rigidity to support heavy-duty clamps. The traction lifting assembly 4 includes a winding wheel 41 rotatably mounted on the side wall of the gantry frame 2, a servo motor 42 driving the winding wheel 41, a traction steel cable 43 wound around the winding wheel 41, and a guide wheel 44 rotatably mounted on the top of the gantry frame 2. The winding wheel 41 can be made of cast iron or cast steel, possessing high strength and wear resistance. The servo motor 42 has precise control performance, capable of accurately controlling the rotation speed and direction of the winding wheel 41 as needed. The traction steel cable 43 is generally made of high-strength steel wire rope, possessing good tensile strength. The guide wheel 44 serves to change the direction of the traction steel cable 43; it can be supported by bearings to reduce friction during rotation. The traction steel cable 43 passes over the guide wheel 44 and is fixedly connected to the lifting platform 3. When the servo motor 42 drives the winding wheel 41 to rotate, the traction steel cable 43 drives the lifting platform 3 to move up and down.
[0026] Reference Figure 2The fork arm assembly 5 includes a horizontally sliding seat 51 mounted on the lifting platform 3, a horizontal drive component 52 for driving the horizontally sliding seat 51, and a bidirectional telescopic fork arm 53 mounted on the horizontally sliding seat 51. A horizontally fixed rail is mounted on the lifting platform 3, and the horizontally sliding seat 51 is slidably mounted on the lifting platform 3 via the rail. The horizontally sliding seat 51 can be made of aluminum alloy, which is lightweight and high-strength. The horizontal drive component 52 can be a rodless cylinder, an electric push rod, or a hydraulic cylinder, providing stable driving force. The bidirectional telescopic fork arm 53 can be made of high-strength alloy steel, possessing good telescopic performance and load-bearing capacity. The extension and retraction of the fork arm can be controlled by a motor or hydraulic system to achieve lateral transport of heavy-duty clamps.
[0027] Reference Figure 2 To ensure smooth sliding of the lifting platform 3, linear guide rails 21 are vertically installed on both sides of the gantry frame 2 and on both sides of the lifting platform 3. Heavy-duty sliders 31 that slide in cooperation with the linear guide rails 21 are respectively installed on both sides of the lifting platform 3. The heavy-duty sliders 31 are usually made of wear-resistant materials, such as copper alloy or engineering plastics, to reduce friction during sliding.
[0028] Reference Figure 3 Furthermore, a load-bearing caliper 32 is rotatably mounted on the heavy-duty slider 31, and a rotary drive component 33 is provided on the heavy-duty slider 31 to drive the load-bearing caliper 32 to deflect. A limit stop 34 is also fixedly provided on the heavy-duty slider 31 to limit the upward deflection angle of each load-bearing caliper 32. Load-bearing sockets 22 for inserting the load-bearing calipers 32 are provided on the linear guide rail 21 at the positions of each layer of clamp storage space 11. The load-bearing calipers 32 can be made of high-strength alloy steel and have good load-bearing capacity.
[0029] Reference Figure 3 Specifically, the rotary drive component 33 includes a telescopic cylinder 331 fixedly mounted on the heavy-duty slider 31, and a connecting rod 332 hinged to the piston rod of the telescopic cylinder 331. The connecting rod 332 is hinged to the load-bearing caliper 32. The telescopic cylinder 331 can provide a stable driving force, which drives the load-bearing caliper 32 to deflect via the connecting rod 332.
[0030] Reference Figure 3The heavy-duty slider 31 is also equipped with an elastic drive element 35, which is a torsion spring. It is sleeved on the rotating shaft of the load-bearing caliper 32, giving the load-bearing caliper 32 an elastic tendency to deflect towards the linear guide rail 21. When the lifting platform 3 is rising, the telescopic cylinder 331 is not working. At this time, the load-bearing caliper 32 deflects towards the linear guide rail 21 under the elastic force of the elastic drive element 35 and always remains in a tight position against the linear guide rail 21. This design does not restrict the lifting platform 3 from continuing to slide upward. If the traction cable 43 breaks, after the lifting platform 3 has slid down a certain distance, the load-bearing caliper 32 will automatically engage with the load-bearing socket 22 of the nearest floor below under the elastic force of the elastic drive element 35, preventing the lifting platform 3 from falling further, thereby improving the safety of the construction site. If it is necessary to lower the lifting platform 3, the telescopic cylinder 331 can be activated and the telescopic rod can be retracted. The connecting rod 332 will drive each load-bearing clamp 32 to deflect away from the linear guide rail 21, and the lifting platform 3 can then slide down smoothly.
[0031] Reference Figure 4 The fixture 6 includes a support base 61 fixedly installed in the fixture storage area, a lifting platform 62 vertically slidably installed on the support base 61, and a hydraulic jack 63 installed on the support base 61 to drive the lifting platform 62 up and down. Two lifting platforms 62 are provided and symmetrically arranged on both sides of the support base 61. The support base 61 is generally welded from steel plates, providing sufficient stability. The lifting platform 62 can be made of cast iron with a precision-machined surface to ensure good contact with the fixture. The hydraulic jack 63 has a large lifting force, enabling it to smoothly lift or lower the fixture.
[0032] Reference Figure 4 A floating support plate 64 is also provided on the support base 61 and located between the two lifting platforms 62. An elastic buffer assembly 65 for supporting the floating support plate 64 is also provided on the support base 61. The floating support plate 64 can be made of high-strength steel plate, possessing good structural strength. The elastic buffer assembly 65 includes multiple springs disposed between the support base 61 and the floating support plate 64, effectively absorbing the impact force when the clamp falls, protecting the clamp and the multi-layered storage frame 1. Alternatively, the elastic buffer assembly 65 can also be made of rubber pads.
[0033] Reference Figure 4 The top of the floating support plate 64 is also fixedly equipped with multiple positioning pins 66. The position of each positioning pin 66 corresponds one-to-one with the positioning hole on the bottom of the heavy-duty fixture, and can be inserted into the corresponding positioning hole of the heavy-duty fixture. The positioning pins 66 are generally made of alloy steel, which has high hardness and wear resistance. The high precision of the fit between the positioning pins 66 and the positioning holes ensures the stability and positioning accuracy of the fixture during storage, and guarantees that it can be accurately aligned with the fork arm assembly 5 during the next part retrieval.
[0034] The implementation principle of a multi-layer heavy-duty automotive parts fixture library according to an embodiment of this application is as follows: The multi-layer structure design of the fixture library's multi-layer frame 1 effectively improves workshop space utilization and reduces floor space. The traction lifting assembly 4 drives the winding wheel 41 to rotate via a servo motor 42, which in turn drives the traction cable 43 to raise and lower the lifting platform 3, realizing the transport of heavy-duty fixtures at different levels. The cooperation between the linear guide rail 21 and the heavy-duty slider 31 improves the stability of the lifting platform 3. The lateral moving seat 51 of the fork arm assembly 5 and the bidirectional telescopic fork arm 53 cooperate to accurately transport heavy-duty fixtures to or retrieve them from the corresponding fixture storage area. The fixture receiving fixture 6 can receive the fixtures transported by the fork arm assembly 5, making it easy for heavy-duty fixtures to be quickly detached from the fork arm assembly 5 for storage. It can also quickly place and transfer heavy-duty fixtures stored in the fixture storage area to the fork arm assembly 5, thereby achieving efficient storage and rapid switching of heavy-duty fixtures, which improves the overall efficiency of automobile production and solves the problems of low space utilization and slow switching efficiency in traditional fixture storage and switching schemes.
[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
