Abstract
The utility model discloses a square flange-type part clamping tool. The square flange-type part clamping tool comprises an annular positioning pedestal and an annular retainer ring, wherein the annular positioning pedestal is arranged at the lower end of the annular retainer ring; the inner ring diameter of the annular positioning pedestal is less than that of the annular retainer ring; a notch is formed on both the annular positioning pedestal and the annular retainer ring; and the notches are overlapped in the vertical direction. The square flange-type part clamping tool is used for positioning and clamping in a square flange-type part in turning process, so that the axle centers are guaranteed to be positioned on the same axis during square flange machining and gland excircle blank face machining without correcting a gland excircle blank face, the machining precision is guaranteed, the machining operation is simple and the working efficiency is improved.
Description
Technical field
The utility model relates to a kind of machine-building instrument, specifically is a kind of square flange type parts fixation instrument.
Background technology
In the car preface processing of in the past inlet and outlet valve gland, adopt chuck to proofread and correct the process that clamps processing always, wherein, chuck is just relatively more complicated surely, man-hour, waste was bigger, simultaneously since gland cylindrical and endoporus do not process, the inside and outside surplus skewness of part cylindrical and endoporus, just inaccurate surely when making the chuck positioning and clamping, so part turns around to add man-hour, chuck clamp square flange around, need carry out the school circle of gland cylindrical black skin, its surplus is evenly distributed, has reduced working (machining) efficiency, and precision is difficult to guarantee.
The utility model content
The technical problems to be solved in the utility model provides a kind of square flange type parts fixation instrument, has solved the traditional diamond-making technique complicated operation, and the inaccurate problem of precision.
The technical solution of the utility model is:
A kind of square flange type parts fixation instrument, comprise annular positioning base and circular collar, described circular collar lower end is provided with described annular positioning base, the inner ring diameter of described annular positioning base is less than the inner ring diameter of described circular collar, all have breach on described circular collar and the positioning base, and breach is overlapping in vertical direction.
The axle center of described annular positioning base and circular collar is positioned on the same axis.
Operation principle of the present utility model is: lathe is clamped gland cylindrical black skin with scroll chuck, the square flange end of the processing gland other end; After square flange one end processes, scroll chuck is clamped the utility model, square flange one end is snapped in the circular collar of the present utility model, the end face of square flange props up the upper surface of annular positioning base, scroll chuck clamps the utility model, presses the machined surface of figure car preface processing gland one end then.
Circular collar described in the utility model has guaranteed that the axle center of square flange processing and the processing of gland cylindrical black skin is positioned at same axis substantially, does not need to proofread and correct gland cylindrical black skin, has guaranteed the precision of processing; Scroll chuck is just to decide automatically, and three-jaw equates apart from the distance in axle center, has improved the efficient of processing, and simple to operate.
When breach described in the utility model has guaranteed that square flange snaps in the utility model, the utlity model has an outside expansionary force, reduced square flange extruding of the present utility model; When having guaranteed that simultaneously scroll chuck clamps the utility model, the extruding force of generation makes breach push to closing direction, has concentrated the extruding force of the utility model outer ring, has guaranteed just deciding of scroll chuck.
The utility model adds square flange type part car preface does not need to use chuck man-hour, and does not need lid cylindrical black skin is proofreaied and correct, direct processing parts, and working (machining) efficiency height not only, and can reach the requirement of quality, part processing precision is guaranteed.
The utility model compared with prior art has the following advantages:
1, working (machining) efficiency improves greatly;
2, operative employee's technical ability can reduce greatly;
3, cut down finished cost, guarantee element precision;
4, safe in process is reliable, simple, convenient.

The specific embodiment
As shown in Figure 1 and Figure 2, square flange type parts fixation instrument, comprise annular positioning base 1, circular collar 2, circular collar 2 lower ends are provided with annular positioning base 1, annular positioning base 1 and circular collar 2 are that one is moulding, its race diameter is identical, and the inner ring diameter of circular collar 2 is greater than the inner ring diameter of annular positioning base 1; All have breach 3 on annular positioning base 1 and the circular collar 2, and the position of breach 3 is identical in vertical direction, the cross section of resilient tool is untight annular.
As shown in Figure 3, square flange part car preface adds man-hour, with the cylindrical black skin of lathe with scroll chuck 4 clamping glands 5, and square flange 6 end faces and the cylindrical of processing gland 5 other ends;
As shown in Figure 4, after square flange 6 one ends process, part turns around, scroll chuck 4 is clamped resilient tool, square flange 6 one ends are snapped in the circular collar 2 of resilient tool, the end face of square flange 6 props up the upper surface (see figure 5) of annular positioning base 1, and scroll chuck 4 clamps resilient tool, presses the machined surface of figure car preface processing gland 5 one ends then.
Claims (2)
