Description

Technical Field

[0001] The utility model relates to a fixing tool which is convenient for machining a valve body. Background Art

[0002] Existing valve body such as Figure 6 As shown, after the valve body 20 is cast, flange holes 230 need to be opened on the first flange 210 and the second flange 220 of the valve body 20. At the same time, the shaft holes 240 and the shaft seats 250 on the front and rear sides of the valve body 20 also need to be machined.

[0003] However, since the flange hole 230, the shaft hole 240 and the shaft seat 250 are distributed on different wall surfaces, the valve body 20 needs to be clamped continuously during processing to adjust the orientation of the valve body 20. During the entire processing process, it is often necessary to clamp 2-3 times to complete the processing of the four surfaces, which is not only time-consuming and labor-intensive, but also has low processing efficiency. In addition, multiple clamping easily leads to deviations in the front and rear clamping positions, which affects the processing accuracy and does not meet production requirements. Further improvement is needed. Utility Model Content

[0022] During the clamping process of the valve body 20, the columnar positioning part 110 is first inserted into the valve body 20 so that the positioning assembly 40 fits against the inner wall of the valve body 20, thereby constraining the front, back, left, and right positions of the valve body 20. Then, the positioning assembly 40 is used to constrain and position the valve body 20 so that the valve body 20 cannot rotate relative to the columnar positioning part 110. Finally, the clamping assembly 30 is connected to the base 10, and the valve body 20 is clamped by the clamping assembly 30 and the base 10 to constrain the up and down positions of the valve body 20. The positional relationship of the clamping process is shown in FIG. Figure 2 and Figure 3 shown.
