[0002] The cutting edge is a machine tool component used in mechanical processing. It has the characteristics of small outer diameter, fewer interference cutters, suitable for high speed, and moderate cutting. It is now widely used in mechanical parts manufacturers and enterprises.

[0003] The existing mechanical linkage type center moves the center out of the center seat through a rotating seat and internal moving parts, and then starts the center lathe to perform a series of processing such as cutting on the mechanical parts to be processed. In the existing small mechanical linkage centers, it is often necessary to adjust the height of the center to adapt to different parts and the cutting positions of the parts, but the method of adjusting the position of the center is usually to increase the height of the base, and external equipment is required to adjust the base. The adjustment process is relatively cumbersome, and the stability after adjustment is poor. At the same time, for parts of different specifications, only adjusting the height cannot accurately process them.

[0004] Therefore, in order to solve the above technical problems, the present application proposes a mechanical linkage top. Utility Model Content

[0010] Preferably, a torsion spring rod is provided on one side of the top seat located on the second positioning plate, and the torsion spring rod is used to support the horizontal axis of the first bolt in a relaxed state.

[0024] The first positioning plate 2 and the second positioning plate 3 are provided with an adjustment component 6, which is used to change the vertical height of the top seat 4 and the top body 5. The adjustment component 6 includes a first moving groove 601 and a second moving groove 602 respectively provided on the first positioning plate 2 and the second positioning plate 3. A horizontal axis 603 is installed through the inside of the top seat 4. The connection part between the horizontal axis 603 and the top seat 4 is a rotation connection, and the horizontal axis 603 extends to the outside of the first moving groove 601 and the second moving groove 602. One side of the top seat 4 is fixedly installed with The clamping block 604 has a threaded rod 606 rotatably mounted on the end of the clamping block 604. The end of the horizontal axis 603 located in the first moving groove 601 is fixedly connected with a threaded seat 605. The threaded rod 606 is threadedly matched with the threaded seat 605. The upper end of the threaded rod 606 is provided with a rotating hexagonal cap 607. The end of the horizontal axis 603 located in the second positioning plate 3 is provided with a first bolt 608. The top seat 4 is located on one side of the second positioning plate 3 and is provided with a torsion spring rod 609. The torsion spring rod 609 is used to hold up the horizontal axis 603 in a relaxed state of the first bolt 608.

[0025] The first bolt 608 at one end of the horizontal axis 603 and the second bolt 704 outside the vertical groove 701 are loosened, and the hexagonal rotating rod is used to rotate the rotating hexagonal cap 607 to drive the threaded rod 606 to rotate. The rotating threaded rod 606 drives the threaded seat 605 to move in the vertical direction. The threaded seat 605 drives the horizontal axis 603 to move in the vertical direction inside the first moving groove 601 and the second moving groove 602, thereby driving the top seat 4 to move in the vertical direction. When one side of the top seat 4 moves vertically, the torsion spring rod 609 provides an upward elastic force for the other side of the top seat 4, so that both sides can move upward without the phenomenon of movement jamming. After adjusting the top seat 4 to a suitable position, tighten the first bolt 608 and the second bolt 704 to fix it. The operation process is simple and labor-saving, and the top seat 4 moved by bolt tightening can maintain a stable state, thereby improving the top proofreading efficiency of the staff.

[0026] An angle assembly 7 is provided on the first positioning plate 2, and the angle assembly 7 is used to adjust the working angle of the top body 5. The angle assembly 7 includes a vertical groove 701 and a horizontal groove 702. The vertical groove 701 is opened on the surface of the first positioning plate 2, and the horizontal groove 702 is opened inside the rotating seat 8. A moving rod 703 is movably installed inside the horizontal groove 702. The moving rod 703 can only slide horizontally in the horizontal groove 702 through a slideway. The top end of the moving rod 703 extends to the outside of the vertical groove 701, and one end of the moving rod 703 extending to the end of the vertical groove 701 is provided with a second bolt 704. A limit block 705 is provided at the bottom of the vertical groove 701. The limit block 705 is used for moving the moving rod 703 to the bottom of the vertical groove 701, and the top body 5 is in a horizontal state.

[0027] When processing parts of different specifications, sometimes only adjusting the height cannot accurately process them. By loosening the second bolt 704, the moving rod 703 is lifted in the vertical groove 701. Since the top seat 4 will rotate around the connection part of the horizontal axis 603 and the top seat 4, the moving rod 703 moves in the vertical groove 701 and also in the horizontal groove 702. The moving trajectory of the moving rod 703 is an arc line, and the center point of the arc is the rotation connection point between the horizontal axis 603 and the top seat 4. After adjusting the angle, the second bolt 704 is tightened, so that the top seat 4 can be deflected and fixed. The operation is simple, so that the device can adjust the height of parts of different models and also perform angle offset, which improves the processing accuracy of the device and greatly improves the practicality of the device.

[0028] The base 1 is provided with two mounting grooves 9 on one side of the top body 5 and the rotating base 8, respectively. The mounting grooves 9 are used to fix the base 1 by an external person.

[0029] Working principle: the staff loosens the first bolt 608 at one end of the horizontal axis 603 and the second bolt 704 on the outside of the vertical groove 701, and uses the hexagonal rotating rod to rotate the rotating hexagonal cap 607 to drive the threaded rod 606 to rotate. The rotating threaded rod 606 drives the threaded seat 605 to move in the vertical direction. The threaded seat 605 drives the horizontal axis 603 to move in the first moving groove 601 and the second moving groove 602 in the vertical direction, thereby driving the top seat 4 to move in the vertical direction. When one side of the top seat 4 moves vertically, the torsion spring rod 609 provides an upward elastic force for the other side of the top seat 4, so that both sides can move upward without the phenomenon of movement jamming. After adjusting the top seat 4 to a suitable position, tighten the first bolt 608 and the second bolt 704 to fix it;

[0030] When dealing with parts of different specifications, the staff loosens the second bolt 704 and lifts the moving rod 703 in the vertical groove 701. Since the top seat 4 will rotate around the connection part between the horizontal axis 603 and the top seat 4, the moving rod 703 moves in the vertical groove 701 and also in the horizontal groove 702. The moving trajectory of the moving rod 703 is an arc line, and the center point of the arc is the rotation connection point between the horizontal axis 603 and the top seat 4. After adjusting the angle, tighten the second bolt 704 so that the top seat 4 can be deflected and fixed.
