Description
Technical field
The utility model relates to a kind of fixture that is used to process the winding arbor extraction press frame.
Background technology
The winding arbor extraction press frame is to guarantee the follow-up rolling performance of seamless steel pipe and the important metallurgical equipment that guarantees seamless steel pipe geometric tolerances parameter in the tube rolling unit, and it adopts three roller transmission conduits, impacted by rolled steel tube.The overall structure of winding arbor extraction press frame (Fig. 1) is that totally enclosed type is mould assembly casing class formation, the whole machining element of frame is various, dimension relationship is complicated, because its special job specification, and the high tired working environment of metallurgical equipment, therefore the integral body of winding arbor extraction press frame is added the selection of benchmark in man-hour and the conversion accuracy of benchmark requires than higher.The winding arbor extraction press frame is the complete series type equipment on the tube rolling production line, every kind of winding arbor extraction press frame can be applicable to the seamless steel pipe of certain limit specification, winding arbor extraction press is put up the spare part that some was used and needed to prepare to group, use when treating tube rolling production line emergency case, so the production quantity of winding arbor extraction press frame is bigger.The fixing means of processing winding arbor extraction press frame is to adopt simple tools such as cushion block, parallels, pressing plate to be installed at present, and the shortcoming of this method is that secondary is installed, the centering difficulty.Because its machining element is many and association is close each other, main winding arbor extraction press frame is a split holding type structure, and the mould assembling of split processing afer bay can occur the mismatch phenomenon to rack slide, lubrication groove about fashionable, so conventional method is installed that precision is not high, efficient is low, waste time and energy.
Summary of the invention
The utility model provides the fixture that is used to process the winding arbor extraction press frame that a kind of number of times that is installed is few, precision is high for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of fixture that is used to process the winding arbor extraction press frame, comprise that two opposite side have the rectangular base of step, are installed in the straight pin at base center, described straight pin upper end is shaped on the frustum of a cone, the expansion sleeve of the internal diameter and frustum of a cone coupling external diameter and winding arbor extraction press frame centre bore coupling is installed on the frustum of a cone, the dish type latch that has centre bore is installed on the expansion sleeve, the adjustment screw of expansion sleeve is installed on the frustum of a cone by the latch centre bore; Described base symmetry both sides are shaped on datum level, and four winding arbor extraction press frame location side plates that have chamfering are installed on two datum levels.
The utility model can also adopt following technical scheme:
Be shaped on annular groove on the internal diameter of described expansion sleeve upper end, the expansion sleeve upper surface is shaped on the arc gap of groove, is shaped on the arc chimb with arc gap coupling on the described latch edge.
Advantage and the good effect that the utlity model has are:
Owing to be shaped on the frustum of a cone in the straight pin upper end, the expansion sleeve of the internal diameter and frustum of a cone coupling external diameter and winding arbor extraction press frame centre bore coupling is installed on the frustum of a cone, install on the expansion sleeve and have dish type latch and adjustment screw, be shaped on datum level in base symmetry both sides in addition, four winding arbor extraction press frame location side plates that have chamfering are installed on two datum levels.Utilize expansion sleeve and location side plate like this, finish being installed, locking of winding arbor extraction press frame, thereby can realize once being installed finishes the processing of the whole machining elements except that preprocessing hole, need not secondary is installed, enhance productivity greatly, in addition the utility model also have simple in structure, be easy to make, location advantage flexibly reliable, easy to use.
