Detailed ways

The specific embodiment of the present utility model is described below.

As shown in Fig. 1, a lathe chuck for an irregularly shaped valve body includes a bottom plate 9, the side of the bottom plate 9 is pinned to the lathe connecting plate 3, and a matching groove 101 for positioning the parts 7 is opened on the surface of the bottom plate 9 , the fitting groove 101 is rectangular. Eccentric locking devices 1 are also respectively installed on the bottom plate 9 at the two adjacent side edges of the matching groove 101; On the inner side of the bottom plate 9, the balance weight 2 is also pinned; on the top of the part 7, the upper plate 4 is also pinned on one side of the lathe connecting plate 3, and the through hole 401 is set on the upper plate 4, and the through hole 401 is connected to the upper plate 4. One end of the mouth, an inner step 402 is also set on the upper plate 4, and a pin hole 403 is also provided longitudinally on one side of the upper plate 4; a pressing device for pressing the parts 7 is also included, and the pressing device includes a placeable The movable platen 5 in the through hole 401, one end of the movable platen 5 extends outward to form a flange 502 for abutting against the inner step 402, and a waist-shaped hole for adjusting the installation position of the movable platen 5 is also provided on the movable platen 5 501 , the locking rod 10 for pressing the part 7 is screwed on the movable pressing plate 5 . The orifice area of the through hole 401 is larger than the volume of the movable platen 5 , so that the movable platen 5 can extend into the through hole 401 .

Concrete work process of the present utility model is as follows:

As shown in Figure 1, when installing, insert the square opening of the part 7 into the matching groove 101 of the bottom plate 9, and rotate the eccentric locking device 1 so that the eccentric part of the eccentric locking device 1 and the two sides of the square opening of the part 7 Adjacent sides abut against each other, so as to realize the positioning of parts 7, the movable pressing plate 5 is stretched in the through hole 401, and the pin 8 penetrates through the pin hole 403 and extends into the waist-shaped hole 501 of the movable pressing plate 5, as shown in Figure 2 As shown, adjust the position of the movable platen 5 so that the flange 502 abuts against the inner step 402, and then rotate the locking lever 10 to abut against the upper surface of the part 7, thereby locking the part 7. When the part 7 needs to be replaced after processing, it is only necessary to move the movable platen 5 through the waist-shaped hole 501 so that the flange 502 of the movable platen 5 does not abut against the inner step 402, and then the movable platen 5 is tilted and stretched out. Holes 401, so that the locking bar 10 releases the locking of the parts 7, and then the replacement parts 7 can be punched and processed. Both sides of the part 7 are supported by the balance weight 2, thereby preventing the part 7 from being easily tilted during processing.

The utility model is simple in structure and easy to use. The arrangement of the balance block can not only realize the support of the parts, but also can fix the center of gravity of the parts and the chuck, and ensure the clamping of the parts through the frame structure formed by the upper plate, the side plate and the lower plate. The matching groove and the eccentric locking device can realize the positioning of the parts and ensure the positioning accuracy of the parts. Processing efficiency.

The above description is an explanation of the utility model, not a limitation of the utility model. For the limited scope of the utility model, refer to the claims. Without violating the basic structure of the utility model, the utility model can be modified in any form.
