Description
Technical field
The utility model relates to the petroleum machinery processing technique field, particularly a kind of clamp for machining of oil pumping machine crank keyway.
Background technology
Oil pumping machine crank is one of most important part in the oil pumper, and the crudy of crank can produce a very large impact machine performance.Have the strict demand for the processing of crank dimensional accuracy and form and position tolerance, also need strictness control is carried out in the price scissors between the auxiliary crank except each position.With the curved beam-pumping unit crank of 14 types is example, and national standard requires the price scissors between the auxiliary crank to be controlled in the 7mm.Present domestic most producers all are by the pincers worker line, and line centering processing keyway is pressed in planing, matches with mandrel at last.So not only production efficiency is low, but also has very big blindness.Qualification rate is hanged down and is caused very big waste.
The utility model content
The purpose of this utility model is: a kind of oil pumping machine crank keyway clamp for machining is provided, improves processing oil pumping machine crank keyway production efficiency, improve crudy and precision.It is low fundamentally to solve oil pumping machine crank keyway processing efficient, the uppity problem of quality.Line centering, artificial selection's hard work amount is pressed in minimizing pincers worker line, planing.
The technical solution adopted in the utility model is: oil pumping machine crank keyway clamp for machining, mainly form by lifting force rod, positioning plate, positioning core axle, swelling cover, pressing plate, bolt, interior six square bolts, gripper shoe, clamp nut and detection reference plate, it is characterized in that: positioning plate is a rectangle ash iron plate, on the end face of two minor faces of positioning plate, perpendicular end surface is fixed with two cylindrical lifting force rods respectively.There are two upright openings on the plane along center line on positioning plate, and the distance of upright opening equates with the distance in two stroke holes of the oil pumping machine crank of needs processing.Be fixed with a positioning core axle in the upright opening respectively.Positioning core axle top is cone, and the top of cone is cylinder, and screw rod is arranged at cylinder top.On cone and cylinder, be with a swelling cover.The outer wall of swelling cover is a cylinder, and the endoporus of swelling cover is identical with the cone tapering of positioning core axle.A disc pressing plate is arranged at the top at the swelling cover.On the positioning core axle screw rod, be fixed with clamp nut.When clamping oil pumping machine crank, the oil pumping machine crank of needs processing is passed through the outside of two stroke borehole jacks at the swelling cover, and be fixed with pressing plate and clamp nut.Oil pumping machine crank is fixed on the positioning plate, can guarantees that the symmetrical centre plane of oil pumping machine crank is parallel with the true edge of positioning plate.Respectively there is a gripper shoe at two ends and middle part at positioning plate, and six square bolts were fixed on the positioning plate in each gripper shoe adopted two.Gripper shoe is planarized to same size after quenching, make the crank end face parallel with location-plate, thereby guarantees that the hole on the crank is vertical with location-plate.In the side of the long limit of positioning plate one end, be fixed with the detection reference plate of a strip.The last plane of detection reference plate perpendicular positioning base plate.
Run into the detection reference plate man-hour in order to prevent to add, influence detects the accuracy of data, is fixed with the Crashworthy plate of a strip in a side of detection reference plate.Crashworthy plate is parallel to the detection reference plate.
The beneficial effects of the utility model: after the utility model oil pumping machine crank keyway clamp for machining is succeeded in developing, effect is very good in actual use, make the price scissors between any two oil pumping machine cranks can be controlled in the 1mm, 7mm than national Specification, large increase has been arranged, thereby improved the complete machine performance of oil pumper.Avoid pincers worker line, the planing operation by line centering, artificial selection simultaneously, reduced labour intensity, make things convenient for crudy to detect, constant product quality has improved production efficiency.
Description of drawings
Fig. 1 is the utility model oil pumping machine crank keyway clamp for machining structural profile schematic diagram.
Fig. 2 is the vertical view of Fig. 1.What dotted line was represented is the oil pumping machine crank of needs processing.
Among the figure, 1. lifting force rod, 2. positioning plate, 3. positioning core axle, 4. swelling cover, 5. pressing plate, 6. bolt, 7. in six square bolts, 8. gripper shoe, 9. clamp nut, 10. Crashworthy plate, 11. detection reference plates.
The specific embodiment
Embodiment 1: consult Fig. 1.The utility model oil pumping machine crank keyway clamp for machining mainly is made up of lifting force rod 1, positioning plate 2, positioning core axle 3, swelling cover 4, pressing plate 5, bolt 6, interior six square bolts 7, gripper shoe 8, clamp nut 9 and detection reference plate 11.
Positioning plate 2 is the rectangle steel plate, long 1000 millimeters, and wide 360 millimeters, 100 millimeters of thickness.On the end face of two minor faces of positioning plate 2, perpendicular end surface is fixed with two cylindrical lifting force rods 1 respectively.During the installation or removal anchor clamps, will lift by crane rope and be connected on the lifting force rod 1.
There are two upright openings on the plane along center line on positioning plate 2, and the distance of upright opening equates that with the distance in two stroke holes of the oil pumping machine crank of needs processing two stroke pitch-rows of the oil pumping machine crank of different model are from inequality, and used anchor clamps are also different.Be fixed with a positioning core axle 3 in the upright opening respectively.Positioning core axle 3 tops are cones, and the length of cone is 120 millimeters, and tapering is 1: 10.The top of cone is cylinder, and screw rod is arranged at cylinder top.On cone and cylinder, be with a swelling cover 4.The outer wall of swelling cover 4 is a cylinder, and the endoporus of swelling cover 4 is identical with the cone tapering of positioning core axle 3.A disc pressing plate 5 is arranged at the top at swelling cover 4.On positioning core axle 3 screw rods, be fixed with clamp nut 9.When clamping oil pumping machine crank, the oil pumping machine crank of needs processing is overlapped 4 outside by two stroke borehole jacks in swelling, and be fixed with pressing plate 5 and clamp nut 9.
Respectively there is a gripper shoe 8 at two ends and middle part at positioning plate 2, and six square bolts 7 were fixed on the positioning plate 2 in each gripper shoe 8 adopted two.Gripper shoe 8 is planarized to same size after quenching, make the crank end face parallel with location-plate, thereby guarantees that the hole on the crank is vertical with location-plate.In the side of the long limit of positioning plate 2 end, be fixed with the detection reference plate 11 of a strip.The last plane of detection reference plate 11 perpendicular positioning base plates 2.Be fixed with the Crashworthy plate 10 of a strip in a side of detection reference plate 11.Crashworthy plate 10 is parallel to detection reference plate 11.70 millimeters of the width of detection reference plate 11,370 millimeters of length.The employing screw is fixed.
The using method of oil pumping machine crank keyway clamp for machining:
Anchor clamps with dial gauge centering datum level, fix anchor clamps with tommyhead bolt on slotting machine.With dial gauge to the datum level of detection reference plate carry out level, vertical both direction carries out centering.Crank is swelling location and reliable with pressing plate, bolting on anchor clamps.Behind side of processing oil pumping machine crank keyway, reprocess another side.Guarantee higher keyway symmetry in actual use, thereby guaranteed the crank price scissors.
