DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] Example: Figure 1-3 As shown, the utility model provides an adjustable center seat, in which a processing table 1 serves as a base, a baffle 4 is provided on the upper end thereof for limiting the position of the workpiece, and a lifting mechanism 2 is also provided on the processing table 1, which is tightly fitted with the processing table 1 through a bottom plate 20, and a lifting frame 21 is fixed above the bottom plate 20, and a lifting platform 23 that can move up and down is provided inside the lifting frame 21, one side of the lifting platform 23 is connected to the positioning screw 25 through a positioning rod 26, and a positioning nut 24 is threaded on the positioning screw 25 to fix the position of the lifting platform 23, and the other side of the lifting platform 23 is connected to the lifting block 29 through a lifting rod 28, and the lifting screw 201 rotatably arranged on the lifting frame 21 cooperates with the lifting block 29 to realize the lifting and lowering adjustment of the lifting platform 23.

[0018] By cooperating with the fixing holes 202 on the base plate 20 and the fixing screw holes 5 on the processing table 1, the lifting mechanism 2 is stably installed and the stability of the overall structure is improved. The lifting grooves 27 on both sides of the lifting platform 23 slide in contact with the inner surface of the lifting frame 21 to ensure the stability and accuracy of the lifting platform 23 during the lifting process. The lifting slides 22 on both sides of the lifting frame 21 cooperate with the positioning rod 26 and the lifting rod 28 respectively to further enhance the flexibility and stability of the lifting mechanism 2.

[0019] The top mechanism 3 is fixedly connected to the inner surface of the lifting platform 23 through the top plate 30. A top rod 33 is provided inside the top plate 30. A top head 39 is provided at one end of the top rod 33, which is used in conjunction with the baffle 4. The other end of the top rod 33 is connected to the movable plate 35. A movable screw 37 is provided on the movable plate 35. A knob 36 is fixed at one end of the movable screw 37. A movable screw groove 31 is provided on one side of the top plate 30, which is used in conjunction with the movable screw 37 to realize the telescopic adjustment of the top rod 33.

[0020] The clamping bolt 38 provided on one side of the top plate 30 is used in conjunction with the top rod 33 and the moving screw 37 to achieve a stable locking of the top mechanism 3 and improve the processing accuracy. The top groove 32 opened on one side of the top plate 30 slides in contact with the outer surface of the top rod 33 to ensure the stability and accuracy of the top rod 33 during the extension and retraction process. The rotating groove 34 opened on one side of the moving plate 35 is rotatably connected to the outer surface of the moving screw 37 to achieve easy adjustment and locking of the top rod 33.

[0021] Working principle: When the height of the top position needs to be adjusted, the lifting screw 201 on the lifting mechanism 2 is rotated. The threaded engagement between the lifting screw 201 and the lifting block 29 generates a lifting force, pushing the lifting rod 28 and the lifting platform 23 up and down in the lifting frame 21. At the same time, the cooperation between the positioning rod 26 and the positioning nut 24 ensures the stability and accuracy of the lifting platform 23 during the lifting process. When the lifting platform 23 reaches the desired height, the positioning nut 24 is tightened to fix the lifting platform 23.

[0022] When the workpiece needs to be fixed at the top, the rotating knob 36 on the top mechanism 3 drives the moving screw 37 to rotate and move in the moving screw groove 31, thereby pushing the moving plate 35 and the top rod 33 to slide in the top plate 30. The top head 39 at one end of the top rod 33 is used in conjunction with the baffle 4 to achieve the top fixation of the workpiece. When the top rod 33 reaches the required position, the top rod 33 and the moving screw 37 are locked on the top plate 30 by the clamping bolt 38 to ensure stability and accuracy during the processing.

[0023] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
