AI Technical Summary
Irregularly shaped parts cannot be directly fitted to lathe chucks for clamping due to their irregular shape. Existing clamping methods are costly, have poor versatility, and are prone to causing part deformation or unstable processing, posing safety hazards.
The base plate is fixed to the lathe chuck jaws. The bottom ear plate of the irregular part is fixed by radial slots on the base plate and connecting bolts and nuts. The slots of the ear plate are supported by L-shaped sliders and springs to improve the connection stability.
It enables stable clamping of irregularly shaped parts on the lathe chuck, improves machining stability and accuracy, avoids part deformation and safety hazards, and reduces production costs.

A precision milling connection and fixing device for irregularly shaped parts and lathe chucks, comprising a base plate (2), characterized in that: The substrate (2) is a round plate with an inner hole (3) in the center. The inner hole (3) is used to fix the chuck jaws of the lathe. A second slot (4) is opened on one side of the substrate (2). The ear plate (101) at the bottom of the irregular part (1) is fixed in the second slot (4).
2. The device for connecting and fixing the special-shaped part and the lathe chuck according to claim 1, characterized in that: The second slot (4) is provided with a through hole (5), which is aligned with the opening (103) on the ear plate (101) of the irregular part (1), and the irregular part (1) is fixed on the substrate (2) by connecting bolts (6) and connecting nuts (7).
3. The device for connecting and fixing the special-shaped part and the lathe chuck according to claim 1, characterized in that: The ear plate (101) of the irregular part (1) is provided with a first slot (102), and the height of the second slot (4) is the same as the thickness of the lower plate of the first slot (102).
4. The device for connecting and fixing the special-shaped part and the lathe chuck according to claim 1, characterized in that: The substrate (2) has two grooves (8) that are perpendicular to the second slot (4). An L-shaped slider (9) is provided in the groove (8). The horizontal part (901) of the L-shaped slider (9) passes through the first slot (102) on the ear plate (101).
5. The device for connecting and fixing the special-shaped part and the lathe chuck according to claim 4, characterized in that: The thickness of the second slot (4) is the same as the thickness of the horizontal part (901) of the L-shaped slider (9).
6. The device for connecting and fixing the special-shaped part and the lathe chuck according to claim 4, characterized in that: The vertical part (902) of the L-shaped slider (9) is located in the groove (8), and a guide rod (10) passing through the vertical part (902) is provided in the groove (8). A spring (11) is fitted on the guide rod (10) on the side of the vertical part (902) away from the second slot (4), and the spring (11) applies a spring force to the vertical part (902) in the direction of the second slot (4).
7. The device for connecting and fixing the special-shaped part and the lathe chuck according to claim 4, characterized in that: The L-shaped slider (9) has a vertical plate (903) on one end of the horizontal part (901) that is located on the same vertical plane as the vertical part (902).
