Description

Technical Field

[0001] This utility model relates to the field of transfer trolley technology, and in particular to a workpiece transfer device for workshops. Background Technology

[0002] In the production process of machining and assembly workshops, parts often need to be repeatedly transferred between multiple workstations. To facilitate the turnover of parts, the commonly used equipment is the flatbed trolley. This type of trolley has a simple structure, usually with only a single-layer platform, and can carry a certain number of parts. However, with the acceleration of production cycles and the increase in the number of parts, the capacity of a single-layer platform is limited, resulting in low transfer efficiency.

[0003] To address the issue of insufficient loading capacity, some transport vehicles have adopted multi-layer structures to accommodate more parts on a single vehicle. However, most existing multi-layer transport vehicles have fixed shelf heights, with no adjustable spacing between layers. This fixed-height design has the following drawbacks: when transporting large parts, they often cannot be placed between the shelves, rendering the multi-layer structure ineffective; conversely, when transporting small parts, the space between layers is wasted, and the vehicle's overall loading capacity remains underutilized. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the height of multi-layer turnover carts cannot be adjusted, and to propose a workshop workpiece transfer device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A workshop workpiece transfer device includes a frame with wheels at the bottom. At least two sets of bearing units are provided on the top of the frame. Multiple bearing units are stacked vertically and adjacent bearing units are movably connected by a scissor frame assembly. Two vertically arranged guide rods are fixed to one side of the frame. The lowermost bearing unit is fixedly connected to the guide rods, and the uppermost bearing unit is drivenly connected to the guide rods. Each bearing unit includes a detachable and replaceable bearing platform.

[0007] The bearing unit includes two symmetrically arranged support rods. The cross-section of the support rods is C-shaped and the openings point inward. A bearing platform is slidably connected between the C-shaped openings of the two support rods. The scissor frame assembly is connected to the support rods.

[0008] The supporting platform is a flat plate structure or a basketball hoop structure.

[0009] At least three load-bearing units are provided above the frame. A vertically arranged support cylinder is fixed to one end of the support rod. The support cylinder of the load-bearing unit at the top is defined as the top cylinder, the support cylinder of the load-bearing unit at the bottom is defined as the bottom cylinder, and the support cylinder of the load-bearing unit in the middle is defined as the middle cylinder. The bottom cylinder is fixed to the guide rod, the middle cylinder is vertically slidably connected to the guide rod, and the top cylinder is drively connected to the guide rod.

[0010] The upper end of the guide rod is rotatably connected to a threaded cylinder, and the top cylinder is threadedly connected to the threaded cylinder.

[0011] The two threaded cylinders are connected by a synchronous transmission component.

[0012] The synchronous transmission component includes pulleys fixed to two threaded cylinders respectively, and the two pulleys are connected by a belt.

[0013] This utility model proposes a workshop workpiece transfer device with the following advantages: Through the coordination of the frame, wheels, load-bearing units, guide rods, scissor frame components, and load-bearing platform, the height between load-bearing units can be flexibly adjusted according to actual needs, thus accommodating parts of different sizes. Compared with traditional transfer vehicles with fixed heights, this device effectively avoids the problem of large parts being unable to be placed or small parts causing wasted space between layers, significantly improving loading rate and transfer efficiency. Simultaneously, the load-bearing platform adopts a detachable and replaceable design, giving the device greater adaptability and flexibility under different working conditions, suitable for the turnover of various types of parts in the workshop.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-3 A workshop workpiece transfer device includes a frame 9, wheels 6 at the bottom of the frame 9, at least two sets of bearing units 12 on the top of the frame 9, multiple bearing units 12 stacked vertically, adjacent bearing units 12 are movably connected by scissor frame assembly 7, two vertically arranged guide rods 4 are fixedly connected to one side of the frame 9, the lowermost bearing unit 12 is fixedly connected to the guide rods 4, and the uppermost bearing unit 12 is pulsatorically connected to the guide rods 4, and each bearing unit 12 includes a detachable and replaceable bearing platform 11.

[0020] Multiple support units 12 are stacked vertically, and adjacent support units 12 are movably connected by a scissor frame assembly 7, allowing relative movement between the support units 12 in the vertical direction. The lowest support unit 12 is fixedly connected to the guide rod 4 to form a reference support. The highest support unit 12 is driven by the guide rod 4. When the guide rod 4 moves the highest support unit 12 up or down, the scissor frame assembly 7 generates a linkage, causing the middle support units 12 to adjust their height simultaneously. Each support unit 12 is equipped with a detachable and replaceable support platform 11. Users can place components on the corresponding support platform 11 according to the specifications of different components, thereby completing the transfer of multi-layer workpieces.

[0021] The device, through the cooperation of the frame 9, wheels 6, load-bearing units 12, guide rods 4, scissor frame assembly 7, and load-bearing platform 11, allows the layer height between the load-bearing units 12 to be flexibly adjusted according to actual needs, thus accommodating parts of different sizes. Compared with traditional fixed-layer transfer vehicles, this device effectively avoids the problem of large-sized parts being unable to be placed or small-sized parts causing wasted space between layers, significantly improving loading rate and transfer efficiency. Meanwhile, the load-bearing platform 11 adopts a detachable and replaceable design, giving the device greater adaptability and flexibility under different working conditions, suitable for the turnover of various types of parts within the workshop.

[0022] The load-bearing unit 12 includes two symmetrically arranged support rods 8. The cross-section of the support rods 8 is C-shaped and the openings point inward. A load-bearing platform 11 is slidably connected between the C-shaped openings of the two support rods 8. The scissor frame assembly 7 is connected to the support rods 8.

[0023] The support unit 12 consists of two symmetrically arranged support rods 8. The support rods 8 have a C-shaped cross-section with the opening facing inwards. A guide groove is formed between the two support rods 8, allowing the support platform 11 to be slidably installed or removed along the guide groove in a drawer-like manner. A scissor-mounted assembly 7 is connected to the support rods 8. When the scissor-mounted assembly 7 raises and lowers the support unit 12, the support platform 11 adjusts its height accordingly, enabling flexible arrangement of different levels. This facilitates the selection of appropriate platform types based on the specifications of different components.

[0024] refer to Figure 3 The supporting platform 11 is a flat plate structure or a basketball hoop structure.

[0025] As one embodiment of the scissor bracket assembly 7, see reference Figure 1 The scissor bracket assembly 7 includes two cross rods distributed in an X shape. One end of the cross rod is rotatably connected to the support rod 8 via a pin, and the other end is rotatably connected to the slider 10 via a pin. The slider 10 is slidably connected to the support rod 8. In one embodiment, the slider 10 can adopt a C-shaped structure.

[0026] At least three load-bearing units 12 are provided above the frame 9. One end of the support rod 8 is fixed to a vertically arranged support cylinder 13. The support cylinder 13 of the load-bearing unit 12 at the top is defined as the top cylinder 1, the support cylinder 13 of the load-bearing unit 12 at the bottom is defined as the bottom cylinder 5, and the support cylinder 13 of the load-bearing unit 12 in the middle is defined as the middle cylinder 3. The bottom cylinder 5 is fixed to the guide rod 4, the middle cylinder 3 is vertically slidably connected to the guide rod 4, and the top cylinder 1 is drive-connected to the guide rod 4. A threaded cylinder 2 is rotatably connected to the upper end of the guide rod 4, and the top cylinder 1 is threadedly connected to the threaded cylinder 2. The two threaded cylinders 2 are drive-connected through a synchronous transmission component 14. The synchronous transmission component 14 includes pulleys fixed to the two threaded cylinders 2 respectively, and the two pulleys are connected by a belt.

[0027] At least three load-bearing units 12 are provided on the top of the frame 9. Each load-bearing unit 12 has a support rod 8 with one end fixed to a vertically arranged support cylinder 13. The support cylinder 13 located at the bottom is defined as the bottom cylinder 5, which is fixedly connected to the guide rod 4 to form the reference of the entire load-bearing system. The support cylinder 13 located in the middle is defined as the middle cylinder 3, which is vertically slidably connected to the guide rod 4 and can move up and down under the guidance of the guide rod 4. The support cylinder 13 located at the top is defined as the top cylinder 1, which is drively connected to the guide rod 4.

[0028] A threaded cylinder 2 is rotatably connected to the upper end of the guide rod 4. A threaded pair is formed between the top cylinder 1 and the threaded cylinder 2. When the threaded cylinder 2 rotates, the top cylinder 1 moves up and down along the guide rod 4 under the action of the thread. The two threaded cylinders 2 are linked together by a synchronous transmission component 14, which consists of pulleys and a belt. The two pulleys are fixed to the two threaded cylinders 2 respectively, and the pulleys are driven by the belt, so that the two threaded cylinders 2 rotate synchronously.

[0029] In practical use, the operator only needs to rotate the threaded cylinder 2, and the top cylinder 1 will rise and fall vertically under the constraint of the guide rod 4, driving the scissor frame assembly connected to it to extend and retract, thereby pushing the middle cylinder 3 to move up and down synchronously, realizing the adjustment of the layer height between each bearing unit 12. This structure allows the bearing platform to flexibly adjust the spacing according to the workpiece size to meet the transfer needs of different parts.

[0030] 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 technical solution, concept, or design obtained by those skilled in the art by making equivalent substitutions or changes based on the technical solution and utility model concept disclosed in the present utility model should be included within the protection scope of the present utility model.
