Abstract
Description
Technical Field
[0001] This utility model relates to a transition plate in the machine tool processing process, and more particularly to a transition plate between the machine tool and the workpiece fixture. Background Technology
[0002] Currently, when machining workpieces on machine tools, a transition plate is typically placed between the machine tool and the fixture. Part of this transition plate is connected to the machine tool via fasteners or a specific structure, while the other part is connected to the fixture. For example, a base plate with through holes is placed on the transition plate, and fasteners such as bolts pass through these through holes to fix the transition plate to the machine tool. To achieve the fixation of the transition plate and the fixture, refer to... Figure 5 On the transition plate, multiple support columns are usually formed by extending axially around the circumference of the substrate. A complete ring is set on the support column. The clamp is radially held on the ring to achieve radial positioning. At the same time, a fixing hole is set on the ring. The clamp and the ring are fixedly connected through the fixing hole to achieve axial and circumferential positioning.
[0003] However, this structure results in a radially outward shift of the overall center of gravity, leading to excessive rotational inertia and limiting the machine tool's rotational speed. Furthermore, different transition plates are required to accommodate different fixtures, increasing material and management costs. Switching between different transition plates necessitates disassembling and reassembling them, further increasing production costs and reducing efficiency.
[0004] Therefore, a new type of machine tool transition plate is needed. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a new machine tool transition plate.
[0006] To solve the above-mentioned technical problems, this utility model provides a machine tool transition plate for connecting a machine tool and a workpiece fixture. It includes a base plate with multiple through holes for fastening devices to pass through and fix the base plate to the machine tool. It also includes multiple positioning posts fixedly connected to the base plate. The multiple positioning posts have a positioning surface for positioning the fixture at the end away from the base plate. The positioning posts also include assembly holes for connecting with the fixture.
[0007] The beneficial effect of this creation is that its simple structure and low rotational inertia help to improve the speed of production and processing. Attached Figure Description

[0013] The following is in conjunction with the appendix Figure 1-4 A clear and complete description is provided for the machine tool transition plate of the present invention.
[0014] A machine tool transition plate for connecting a machine tool (not shown) and a workpiece fixture 40 includes a base plate 10. The base plate 10 has multiple through holes 11 for fastening devices (not shown) to pass through and fix the base plate 10 to the machine tool. The base plate 10 is typically a metal plate, and the fastening devices are most commonly fastening bolts or fixing fixtures on the machine tool.
[0015] The machine tool transition plate also includes first and second positioning surfaces 23 and 24 that overlap or at least partially overlap in axial height, and a plurality of positioning posts 20 fixedly connected to the base plate 10. Each positioning post 20 has a positioning surface 23 and 24 at its end away from the base plate 10 for positioning the workpiece fixture. Each positioning post 20 also includes an assembly hole 25 for connecting with the fixture. The fixed connection between the positioning post 20 and the base plate 10 includes common methods such as welding, bolting, riveting, and threading. The positioning surfaces 23 and 24 ensure accurate radial positioning of the fixture after it is assembled onto the transition plate, while the end face of the positioning post 20 can also achieve axial positioning with the fixture. The assembly hole 25 on the positioning post 20 can mate with the holes in the fixture, using a fixture such as a bolt. This achieves a stable connection between the fixture and the positioning post 20, i.e., a stable connection between the fixture and the transition plate. Using only one positioning post 20 to fix the fixture results in a simple structure, low rotational inertia, and helps to improve production speed.
[0016] Optionally, each positioning post 20 is provided with multiple radially spaced positioning surfaces 23 and 24. This allows the same machine tool transition plate positioning post 20 to be adapted to different fixtures. In production, this reduces the number of transition plates, lowering production and management costs. It also avoids the need for constant disassembly and reassembly of the transition plate to adapt to different fixtures, reducing time costs and improving production efficiency. Preferably, the multiple positioning surfaces 23 and 24 of each positioning post 20 are staggered in axial height (not shown), and the axial height of the radially inner positioning surface is lower than that of the radially outer positioning surface. (Reference) Figure 2Optionally, the first and second positioning surfaces 23 and 24 on each positioning post 20 at least partially overlap in axial height. The plurality of positioning surfaces 23 and 24 extend axially, facilitating the axial assembly and disassembly of the fixture. Preferably, the positioning surfaces 23 and 24 are arc-shaped, with the radius of the arc being the distance from the positioning surfaces 23 and 24 to the rotation axis of the substrate 10. This allows the positioning surfaces 23 and 24 to be manufactured using the same positioning center during the processing of the transition plate, simplifying manufacturing. In other embodiments, the positioning surfaces 23 and 24 of each positioning post 20 may also be other shapes, such as two intersecting planes forming an angle (not shown).
[0017] Preferably, the positioning post 20 includes a cylindrical rod portion 22 and a generally disc-shaped tail portion 21. The positioning surfaces 23 and 24 are disposed on the disc-shaped tail portion 21. (Reference) Figure 2-3 To establish the first positioning surface 23 and the assembly hole 25, a groove and a circular countersunk hole 25 need to be machined. (Reference) Figure 2 , 4 In other embodiments, the tail portion 21 where the second positioning surface 24 is located is completely removed, forming first and second positioning surfaces 23 and 24 that overlap or at least partially overlap in axial height. Therefore, the tail portion 21 is not a complete disc shape. Alternatively, in other embodiments, the radially inner portion of the tail corresponding to the first positioning surface 23 can be removed, making the second positioning surface 24 and the first positioning surface 23 form a stepped shape. Optionally, the tail portion corresponding to the second positioning surface 24 is not removed, and a complete circular tail portion is retained.
[0018] To provide better radial support for the positioning post 20, the machine tool transition plate in this invention also includes a plurality of support posts 30 disposed on the base plate 10, the support posts 30 extending axially from the base plate 10 in the same direction as the positioning post 20. The support posts 30 at least partially support the positioning post 20 radially outward, providing radial support to the positioning post 20. Preferably, the support post 30 includes a support rod 31 and a support portion 32 extending circumferentially at the other end of the support post 30 relative to the base plate 10, conforming to the radial outward of the positioning post 20, providing radial support to the positioning post 20. Optionally, the support post 30 is disposed radially outward of the positioning post 20 and engages with the positioning post 20 to provide radial support to the positioning post 20; the engagement is preferably conforming to the shape for better support. The support post 30 is provided with fastening holes 33 for engaging with fasteners to fix a clamp to the support post 30.
[0019] The above technical solutions are merely illustrative of the embodiments of this utility model and are not intended to limit the utility model. All equivalent changes made by those skilled in the art based on the creation of this utility model shall fall within the protection scope of this utility model.
