Abstract
Description
Technical Field
[0001] This utility model relates to the field of transfer vehicle technology, and in particular to a workpiece transfer vehicle. Background Technology
[0002] With the development of modern manufacturing, the efficiency of workpiece transfer on the production line has become a key factor in improving overall production efficiency. Traditional workpiece transfer methods typically rely on simple manual handling or the use of basic transport tools such as flatbed trucks or forklifts. However, when dealing with a large number of heavy or precision workpieces, there are problems of low efficiency and insufficient safety; especially when transferring milling tools on lathes, they need to be limited, but the tools have different sizes, and different sizes of tools require different limiting devices. A single transfer cart cannot transfer multiple sizes of tools simultaneously, reducing the efficiency of transfer. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a workpiece transfer cart that solves the problem that existing transfer carts cannot meet the limiting requirements for workpieces of various sizes.
[0004] According to the embodiments of this utility model, the following technical solution is adopted:
[0005] A workpiece transfer device, comprising:
[0006] Transfer vehicle;
[0007] Multiple positioning posts are spaced apart on the transfer vehicle. Each positioning post has an inner cavity with multiple openings along the circumference of the inner cavity.
[0008] Multiple limiting blocks are movable in one-to-one correspondence with multiple openings, for extending into or out of the openings;
[0009] A drive assembly, located in the inner cavity, is used to synchronously drive multiple limiting blocks. The drive assembly includes a cooperating threaded rod and a slide. The threaded rod is rotatably disposed in the inner cavity, and the slide is sleeved on the threaded rod and movably connected to the multiple limiting blocks.
[0010] Preferably, the limiting block and the slide are connected by a connecting rod. The connection points between the connecting rod and the limiting block, and between the connecting rod and the slide, are respectively provided with a first hinge point and a second hinge point, so that the limiting block can be driven to extend into or out of the opening under the action of external force.
[0011] Preferably, both the limiting block and the slide are provided with lifting lugs, and the connecting rod is hinged to the corresponding lifting lug to form the first hinge point and the second hinge point.
[0012] Preferably, the opening is provided with two limiting plates that are spaced apart, and the limiting block is slidably disposed between the two limiting plates.

[0021] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solutions of this utility model are further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.
[0022] See Figures 1 to 3 This utility model provides a workpiece 1 transfer device, comprising:
[0023] Transfer vehicle 2;
[0024] Multiple positioning posts 3 are spaced apart on the transfer vehicle 2. Each positioning post 3 has an inner cavity 4 and multiple openings 5 are provided along the circumference of the inner cavity 4.
[0025] Multiple limiting blocks 6 are movably disposed in multiple openings 5, one by one, for extending into or out of the openings 5;
[0026] A drive assembly is disposed in the inner cavity 4 for synchronously driving multiple limiting blocks 6. The drive assembly includes a threaded rod 7 and a slide 8 that cooperate with each other. The threaded rod 7 is rotatably disposed in the inner cavity 4, and the slide 8 is sleeved on the threaded rod 7 and movably connected to multiple limiting blocks 6.
[0027] In this embodiment, multiple positioning posts 3 are installed on the transfer vehicle 2. The positioning posts 3 provide positioning points for the workpiece 1 (the workpiece 1 is a circular lathe milling tool with a positioning hole at its center). Multiple workpieces 1 are sequentially placed on the positioning posts 3 from top to bottom to realize the transfer of multiple workpieces 1. In order to ensure the stability of the workpiece 1 during transfer, each positioning post 3 has an inner cavity 4 and multiple openings 5 arranged around the inner cavity 4. Multiple limiting blocks 6 can extend into or out of the openings 5 on the positioning post 3 as needed to tightly clamp the workpiece 1 placed on the positioning post 3 and prevent it from moving during transportation. The drive assembly is located inside the inner cavity 4 of the positioning post 3. The drive assembly is responsible for synchronously controlling the movement of all limit blocks 6. It consists of a threaded rod 7 and a slide block 8. The threaded rod 7 can rotate in both directions within the inner cavity 4, while the slide block 8 is fitted onto the threaded rod 7 and connected to each limit block 6. When the threaded rod 7 rotates in both directions, it drives the slide block 8 to move back and forth along its length, thereby causing all connected limit blocks 6 to move back and forth simultaneously and extend into or out of the opening 5 to abut against the inner wall of the workpiece 1, so as to clamp workpieces 1 of different sizes. When limiting workpieces 1 of different sizes, simply place the workpieces 1 of different sizes on the positioning post 3, and the rotation of the threaded rod 7 will cause the limit blocks 6 to abut against the inner wall of the workpiece 1.
[0028] The limiting block 6 and the slide block 8 are connected by a connecting rod 9. The connecting rod 9 and the limiting block 6, as well as the connecting rod 9 and the slide block 8, are respectively provided with a first hinge point and a second hinge point, so that under the action of external force, the limiting block 6 can be driven to extend into or out of the opening 5.
[0029] In this embodiment, the connecting rod 9 is used to connect the limiting block 6 to the slide block 8 to realize the extension and retraction of the limiting block 6.
[0030] The first hinge point and the second hinge point are located at the connection between the connecting rod 9 and the limiting block 6 and the connection between the connecting rod 9 and the slide block 8, respectively. Through these two hinge points, the limiting block 6 can extend or retract in a hinged manner under the action of external force (such as the force generated by the rotation of the threaded rod 7 of the drive assembly).
[0031] Both the limiting block 6 and the slide block 8 are provided with lifting lugs 10, and the connecting rod 9 is hinged to the corresponding lifting lug 10 to form the first hinge point and the second hinge point.
[0032] In this embodiment, both the limiting block 6 and the slide block 8 are provided with lugs 10. The two ends of the connecting rod 9 are hinged to the lugs 10, thereby forming a first hinge point (located at the lugs 10 on the limiting block 6) and a second hinge point (located at the lugs 10 on the slide block 8), so that the connecting rod 9 can rotate freely within a certain angle range, ensuring that the limiting block 6 can smoothly extend into or out of the opening 5 of the positioning post 3, while maintaining synchronous movement with the slide block 8.
[0033] The opening 5 is provided with two limiting plates 11 arranged at intervals, and the limiting block 6 is slidably disposed between the two limiting plates 11.
[0034] In this embodiment, two limiting plates 11 are provided at intervals at each opening 5. The function of the two limiting plates 11 is to provide a sliding track for the limiting block 6, so as to ensure that it can accurately extend into or out of the opening 5 along a predetermined path.
[0035] The cross-section of the limiting block 6 is circular arc-shaped.
[0036] In this embodiment, the arc-shaped design can better adapt to workpieces 1 of different shapes, especially for workpieces 1 with curved contours, it can provide better fit and support, and reduce the shaking of workpieces 1 during transportation.
[0037] The arc surface of the limiting block 6 is provided with a rubber pad, which is attached to the inner side of the tooling.
[0038] In this embodiment, a rubber pad (not shown) is provided on the arc surface of the limiting block 6 to ensure that the limiting block 6 can firmly fix the workpiece 1 and reduce the sliding or movement of the workpiece 1 during the transfer process.
[0039] The threaded rod 7 extends along its axial direction to form a drive rod 12, and the drive rod 12 is provided with a handle 13.
[0040] In this embodiment, the threaded rod 7 extends along its axial direction to form a drive rod 12. A handle 13 is provided at one end of the drive rod 12, providing the operator with a convenient part to hold and apply force, making manual operation more convenient and comfortable. The operator can directly rotate the drive rod 12 by hand to control the rotation of the threaded rod 7, thereby synchronously driving multiple limit blocks 6 to extend or retract, so as to limit the workpiece 1 of different sizes.
[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
