Description

Technical Field

[0001] The present application relates to a transition plate used in a machine tool processing process, and in particular to a transition plate between a machine tool and a workpiece fixture. Background Art

[0002] Currently, when machining workpieces on machine tools, a transition plate is usually set between the machine tool and the fixture. One part of the transition plate is connected to the machine tool through fasteners or specific structures, and the other part is connected to the fixture. For example, a base plate is set on the transition plate, and a through hole is set on the base plate. Fasteners such as bolts pass through the through hole to fix the transition plate to the machine tool. In order to achieve the fixation of the transition plate and the fixture, refer to Figure 5 The transition plate usually has multiple support columns extending axially outside the circumference of the base plate. A full circle of circular rings is set on the support columns. The clamp is radially clamped on the circular ring to achieve radial positioning. At the same time, a fixing hole is set on the circular ring. The clamp and the circular ring are fixedly connected through the fixing hole to achieve axial and circumferential positioning.

[0003] However, this structure suffers from a radially outward shift in the center of gravity, resulting in excessive rotational inertia and limited machine speed. Furthermore, different transition plates are required to accommodate different fixtures, increasing material and management costs. Switching between different transition plates requires disassembly and assembly, increasing production costs and reducing efficiency.

[0004] Therefore, a new machine tool transition plate is needed. Summary of the Invention

[0005] The technical problem to be solved by this application is to provide a new machine tool transition plate.

[0006] In order to solve the above technical problems, the present application provides a machine tool transition plate for connecting the machine tool and the workpiece fixture, including a base plate, on which a plurality of through holes are provided for the fastening device to pass through and fix the base plate on the machine tool, and also includes a plurality of positioning columns fixedly connected to the base plate, and the plurality of positioning columns are provided with a positioning surface for positioning the fixture at one end away from the base plate, and the positioning columns also include an assembly hole for connecting to the fixture.

[0007] The beneficial effect of this invention is that it has a simple structure and small rotational inertia, which helps to increase the speed of production and processing. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The following will clearly and completely describe the machine tool transition plate of this application in conjunction with the attached Figures 1-4 drawings.

[0014] A machine tool transition plate is used to connect a machine tool (not shown) and a workpiece fixture 40, and includes a base plate 10. A plurality of through holes 11 are provided on the base plate 10 for a fastening device (not shown) to pass through and fix the base plate 10 on the machine tool. The base plate 10 is usually a metal plate, and the most common fastening device is a fastening bolt or a fixing jig on the machine tool.

[0015] The machine tool transition plate further includes a plurality of positioning columns 20 fixedly connected to the base plate 10, and first and second positioning surfaces 23, 24 formed to overlap axially in height or at least partially overlap. The plurality of positioning columns 20 are provided with positioning surfaces 23, 24 for positioning the workpiece fixture at the end far from the base plate 10. The positioning columns 20 further include assembly holes 25 for connecting with the fixture. The fixed connection between the positioning columns 20 and the base plate 10 includes common fixing methods such as welding, bolt fixing, riveting, and threading. The positioning surfaces 23, 24 enable the fixture to be accurately positioned radially after being assembled to the transition plate, and at the same time, the end surfaces of the positioning columns 20 can also be positioned axially with the fixture. The assembly holes 25 provided on the positioning columns 20 can cooperate with the holes of the fixture and be combined through a jig, such as a bolt. Thus, a stable combination of the fixture and the positioning columns 20 is achieved, that is, a stable combination of the fixture and the transition plate. Using only the structure of one positioning column 20 to fix the fixture has a simple structure and a small rotational inertia, which helps to improve the production and processing speed.

[0016] Optionally, a plurality of positioning surfaces 23, 24 spaced radially are provided on each positioning column 20. Then, the positioning columns 20 of the same machine tool transition plate can be adapted to different fixtures. In production, the number of transition plates can be reduced, the production cost and management cost can be reduced, and at the same time, the continuous disassembly and assembly of the transition plate when adapting different fixtures during use are avoided, and the time cost is also reduced, improving the production efficiency. Preferably, the plurality of positioning surfaces 23, 24 of each positioning column 20 are axially staggered in height (not shown), and the positioning surface on the radially inner side is lower in axial height than the positioning surface on the radially outer side. Refer to Figure 2, Optionally, the first and second positioning surfaces 23, 24 on each positioning post 20 at least partially overlap in the axial height. The plurality of positioning surfaces 23, 24 extend in the axial direction, facilitating the assembly and separation of the fixture in the axial direction. Preferably, the positioning surfaces 23, 24 are arc-shaped, and the radius of the arc is the distance from the positioning surfaces 23, 24 to the rotation axis of the substrate 10. Then, when machining the transition disk, the same positioning center can be used to machine and manufacture the positioning surfaces 23, 24, facilitating production and manufacturing. In other embodiments, the positioning surfaces 23, 24 of each positioning post 20 can 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 substantially disk-shaped tail portion 21. The positioning surfaces 23, 24 are provided on the disk-shaped tail portion 21. Refer to Figures 2-3 , in order to set the first positioning surface 23 and the assembly hole 25, a groove type and a circular counterbore 25 need to be machined. Refer to Figure 2 , 4 , in other embodiments, the tail portion 21 where the second positioning surface 24 is located is completely cut off, forming the first and second positioning surfaces 23, 24 that overlap or at least partially overlap in the axial height. Therefore, the tail portion 21 is not a complete disk shape. Additionally, in other embodiments, the radially inner part corresponding to the tail portion and the first positioning surface 23 can be cut off, 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 cut off, and the complete circular tail portion is still retained.

[0018] To achieve better radial support for the positioning post 20, the machine tool transition disk in this creation further includes a plurality of support posts 30 provided on the substrate 10. The support posts 30 axially extend from the substrate 10 in the same direction as the positioning posts 20. The support posts 30 at least partially support on the radially outer side of the positioning posts 20, providing radial support for the positioning posts 20. Preferably, the support post 30 includes a support rod 31 and a support portion 32 that extends circumferentially at the other end of the support post 30 relative to the substrate 10, is designed to be similar to the radially outer side of the positioning post 20, and provides radial support for the positioning post 20. Optionally, the support post 30 is provided on the radially outer side of the positioning post 20 and engages with the positioning post 20 to provide radial support for the positioning post 20. The engagement is preferably designed to be similar, achieving better support. The support post 30 is provided with fastening holes 33 for cooperating with fasteners to fix the fixture on the support post 30.

[0019] The above technical solutions are only illustrative of the embodiments of the present application and do not limit the present application. Any equivalent changes made by those skilled in the art based on the creation of the present application fall within the protection scope of the present application.
