The specific embodiment
Embodiment 1:
Consult Fig. 1.Oil pumper crossbeam bearing bottom surface connecting bolt hole processing clamp mainly is made up of gib head pressing plate 1, fishbolt 2, bushing plate 3, connecting bolt 4, drill jig cover 5, draw-in groove plate 6, holddown plate 7, locating shaft 8, spacer 9, location-plate 10, support backing plate 11 and positioning key 12.Bushing plate 3 be shaped as the rectangle steel plate, the thickness of steel plate is 50 millimeters.End at bushing plate 3 has and corresponding four through holes in connecting bolt hole, oil pumper crossbeam bearing bottom surface, and a drill jig cover 5 has closely cooperated in each through hole.Have a location-plate 10 to support at the middle part of bushing plate 3, the thickness of location-plate 10 is 60 millimeters.Location-plate 10 and 3 one-tenth 90 ° of bushing plates.Fixing between location-plate 10 and the bushing plate 3 by eight connecting bolts 4.
Consult Fig. 2.Two gib head pressing plates 1 are arranged on bushing plate 3, a fishbolt 2 is arranged on each gib head pressing plate 1.Gib head pressing plate 1 screws and oil pumper crossbeam bearing can be hooked, and screws fishbolt 2 lower plane of oil pumper crossbeam bearing plane and bushing plate 3 is adjacent to, and guarantees that oil pumper crossbeam bearing locatees up and down.
Consult Fig. 1.On location-plate 10 vertical direction slideway is arranged, locating shaft 8 can move in its inside.Be with spacer 9 on the locating shaft 8.There is axial screw the end of locating shaft 8, axially on the screw fishbolt 2 is arranged, and fishbolt 2 is by discoid holddown plate 7 fastening workpiece.The diameter of locating shaft 8 is identical with the spindle hole diameter of oil pumper crossbeam bearing.Locating shaft 8 is inserted in the spindle hole of oil pumper crossbeam bearing, make location, oil pumper crossbeam bearing front and back.After tightening fishbolt 2, holddown plate 7 compresses end face of oil pumper crossbeam bearing spindle hole, makes the other end of oil pumper crossbeam bearing spindle hole be close to spacer 9, guarantees to locate about oil pumper crossbeam bearing.
Consult Fig. 1.Have rectangle positioning key 12 to fix along bushing plate 3 vertical centre positions in the upper end of location-plate 10, the lower end of location-plate 10 has two to support backing plate 11.
Consult Fig. 2.A draw-in groove plate 6 is arranged between two gib head pressing plates 1.
The operation principle of summary oil pumper crossbeam bearing bottom surface connecting bolt hole processing clamp helps to understand the utility model.Location-plate 10 guarantees 90 ° of connections by connecting bolt 4 and bushing plate, and the positioning key 12 of packing into prevents its rotation, and guarantees that location-plate 10 becomes 90 ° with bearing symmetrical centre plane.Be processed with slot as slideway on the location-plate 10, be processed with the square diameter of axle on the locating shaft 8 and be mated, left and right directions guarantees 0.1~0.15mm gap, guarantees the 4mm gap up and down, make locating shaft 8 to move up and down in location-plate 10 slots, strictness simultaneously limits its amount of swinging.Determine the actual size of spacer according to location-plate 10 to the physical location of drill jig cover 5, so that guarantee the size of spindle hole hole end surface to connecting bolt hole symmetrical centre.On common pressing plate radial drill workbench that bushing plate 3 is fixing, make that supporting backing plate 11 closely contacts with the vertical plane of workbench.The downward pressure that produces when holing like this can be delivered on the workbench, prevents bushing plate 3 bendings, guarantees the design of Clamping Apparatus precision.When determining to support the thickness of backing plate 11, should guarantee that locating shaft 8 rear end faces to workbench vertical plane has the 3mm gap.During use, earlier oil pumper crossbeam bearing is enclosed within on the locating shaft 8, has the gib head pressing plate 1 of open slot that oil pumper crossbeam bearing is hooked by the centre, tighten fishbolt 2 oil pumper crossbeam base-plate plane and bushing plate 3 are developed.The fishbolt 2 of screwed in place axle 8 ends is close to spacer by holddown plate 7 with oil pumper crossbeam bearing spindle hole end face and is fixed on the location-plate 10 then.The last fishbolt of further tightening on the gib head pressing plate 12.Everything is ready just can hole in the back.Loosening in boring procedure in order to prevent workpiece, in first hole, put into an alignment pin after having bored first hole, bore second hole again.Put into an alignment pin again after second hole drill is intact, the 3rd, the 4th hole just can directly have been bored.The purposes of draw-in groove plate 6 prevents when tightening fishbolt 2 exactly that gib head pressing plate 1 from rotating.After porose the processing of institute, extract alignment pin 8 out, loosening fishbolt 2 takes off gib head pressing plate 1 and holddown plate 7, and oil pumper crossbeam bearing is unloaded.
