Description
Technical field
The utility model relates to gas meter, flow meter valve body transverse holes Vehicle Processing technology, is related specifically to a kind of gas meter, flow meter valve body transverse holes workpiece machining clamp.
Background technology
The shape of gas meter, flow meter valve body is similar to three-way connection, wherein has a transverse holes to need to machine.The Vehicle Processing of prior art gas meter, flow meter valve body transverse holes adopts chuck to clamp on engine lathe.Because gas meter, flow meter valve body blank adopts casting or die casting mode to produce usually, its profile is more irregular, in clamping process, because valve body blank profile is irregular, cannot put in place by clamping when causing it to clamp, need the longer time to adjust chuck, can accurately grip.For ensureing that processing smoothly, only has the way adopting artificial screening, valve body blank larger for appearance difference is selected and eliminated.Obviously, prior art gas meter, flow meter valve body transverse holes Vehicle Processing technology also exists clamping difficulty, the problem such as need manually to carry out screening and yield rate is lower.
Summary of the invention
For solving the clamping difficulty that prior art gas meter, flow meter valve body transverse holes Vehicle Processing technology exists, the problem such as need manually to carry out screening and yield rate is lower, the utility model proposes a kind of gas meter, flow meter valve body transverse holes workpiece machining clamp.The utility model gas meter, flow meter valve body transverse holes workpiece machining clamp, comprises U-shaped frame, clamp column, positioning baseplate, pressing plate, pull bar and stage clip; Clamp column is arranged on the back side of U-shaped frame; Positioning baseplate is arranged on a limit medial surface of U-shaped frame, and pressing plate is arranged on the another side medial surface of U-shaped frame, and both are relative; The opposite face of described positioning baseplate and pressing plate is provided with the cylindrical and regular hexagon matched with valve body blank to be processed straight port profile protruding; Center, the back side cylinder lever connecting rod of described pressing plate and be set with stage clip on pull bar; Pull bar is provided with cylinder stopping step and draw ring through after U-shaped edge; Further, the position of positioning baseplate and pressing plate and height are held in the transverse holes center line of valve body blank to be processed and clamp column center line between the two with valve body blankholder to be processed and are coaxially as the criterion.
The Advantageous Effects of the utility model gas meter, flow meter valve body transverse holes workpiece machining clamp to clamp valve body blank easily, and not by the impact whether valve body blank profile regular, and structure is simple, and cost of manufacture is lower.

Detailed description of the invention
Accompanying drawing 1 is the schematic three dimensional views of gas meter, flow meter valve body, and as seen from the figure, the shape of gas meter, flow meter valve body is similar to three-way connection, wherein has a transverse holes to need Vehicle Processing.The Vehicle Processing of prior art gas meter, flow meter valve body transverse holes adopts chuck to clamp on engine lathe.Because gas meter, flow meter valve body blank adopts casting or die casting mode to produce usually, its profile is more irregular, in clamping process, because valve body blank profile is irregular, cannot put in place by clamping when causing it to clamp, need the longer time to adjust chuck, can accurately grip.For ensureing that processing smoothly, only have the way adopting artificial screening, valve body blank larger for appearance difference is selected and eliminated, obviously, prior art gas meter, flow meter valve body transverse holes Vehicle Processing technology also exists clamping difficulty, the problem such as need manually to carry out screening and yield rate is lower.
Accompanying drawing 2 is the structural representation of the utility model gas meter, flow meter valve body transverse holes workpiece machining clamp, accompanying drawing 3 is the schematic diagram of the utility model gas meter, flow meter valve body transverse holes workpiece machining clamp clamp position, in figure, 1 is U-shaped frame, and 2 is clamp column, and 3 is positioning baseplate, 4 is pressing plate, 5 is pull bar, and 6 is stage clip, and A is valve body blank.As seen from the figure, the utility model gas meter, flow meter valve body transverse holes workpiece machining clamp, comprises U-shaped frame 1, clamp column 2, positioning baseplate 3, pressing plate 4, pull bar 5 and stage clip 6; Clamp column 2 is arranged on the back side of U-shaped frame 1; Positioning baseplate 3 is arranged on a limit medial surface of U-shaped frame 1, and pressing plate 4 is arranged on the another side medial surface of U-shaped frame 1, and both are relative; The opposite face of described positioning baseplate 3 and pressing plate 4 is provided with the cylindrical and regular hexagon matched with valve body blank A to be processed straight port profile protruding; Center, the back side cylinder lever connecting rod 5 of described pressing plate 4 and be set with stage clip 6 on pull bar 5; Pull bar 5 is provided with cylinder stopping step and draw ring through behind U-shaped frame 1 limit; Further, the position of positioning baseplate 3 and pressing plate 4 and height are clamped in the transverse holes center line of valve body blank A to be processed and clamp column 2 center line between the two with valve body blank A to be processed and are coaxially as the criterion.The transverse holes of the utility model gas meter, flow meter valve body transverse holes workpiece machining clamp to gas meter, flow meter valve body blank is adopted to add man-hour, first clamp column is clamped on the scroll chuck of lathe, the instrument of crowbar or handle one class is adopted to pull out pull bar by draw ring, distance between pressing plate and positioning baseplate is increased, valve body blank to be processed is placed on positioning baseplate, and straight for valve body blank port is placed with in cylindrical protrusions and regular hexagon projection composition hole, because cylindrical and regular hexagon projection match with the straight port profile of valve body blank, therefore, should facilitate, put into accurately.Releasing lever, pressing plate moves down under the effect of stage clip, now, note another the straight port hole that pressing plate inner face is made up of cylindrical protrusions and regular hexagon projection being equally buckled in valve body blank, thus, valve body blankholder is held in location and to narrow between pressing plate and convenient, accurately and be firmly fixed in U-shaped frame.The transverse holes center line of valve body blank to be processed is between the two held in valve body blankholder to be processed and clamp column center line is coaxially as the criterion due to the position of positioning baseplate and pressing plate and height, therefore, valve body blank to be processed thinks that empty center is just positioned at pivot very much.Because the utility model gas meter, flow meter valve body transverse holes workpiece machining clamp adopts positioning baseplate and pressing plate to fix valve body blank to be processed, reduce the dependence to valve body blank size, go for most valve body blank.In addition, suitably can also relax the dimensional requirement of cylindrical protrusions and regular hexagon projection, so that adapt to the clamping of the more irregular valve body blank of more profiles.
Obviously, the Advantageous Effects of the utility model gas meter, flow meter valve body transverse holes workpiece machining clamp to clamp valve body blank easily, and not by the impact whether valve body blank profile regular, and structure is simple, and cost of manufacture is lower.
