Abstract
Description
Technical field
The utility model relates to a kind of clamping tool for machine work, particularly a kind of drilling clamp for machining.
Background technology
Crank is the part of bent axle, and the oilhole on its outer wall is very high with respect to the position accuracy demand of crank hole, and prior art generally adopts the V shape iron positioning support and is aided with template and compresses, and the drill jig of this version can be effective to the positioning and drilling oilhole.But the hole site precision that prior art processes is not high, and clamping unproductive time is long, work efficiency is poor, can not satisfy requirement of mass production.
The utility model content
The utility model is primarily aimed at the deficiencies in the prior art, proposes the positioning and drilling fixture for crank oil hole that a kind of location structure is reasonable, making is easy, positioning accuracy is high, charge and discharge operations is easy.
The utility model is achieved through the following technical solutions technical goal.
Positioning and drilling fixture for crank oil hole, it comprises base, transition supporting, live centre, drill jig frame and decides thimble.A contour column is respectively established at two ends, the described base left and right sides, and two column tops are equipped with coaxial axially extending bore, and the left end through hole is equipped with axle sleeve, the also equipped axle sleeve of right-hand member through hole, axially fixedly connected side by side drill jig frame and transition supporting between base two columns.Described drill jig top of the trellis is provided with logical up and down drill bushing.Described live centre stage casing is a helical axis, and the guide blot that is provided with on this section helical axis and the base left end column fits in the axial screw adjustment structure, and the live centre left end is fixedlyed connected with handwheel, and right-hand member is a thimble.Its improvements are: describedly decide behind the tailstock barrel shock mount and the axle sleeve matched in clearance, decide the thimble right-hand member connect by bolt, nuts and washers form with respect to base right column axial adjustment structure.By the alignment pin auxilliary pad that is located by connecting, transition supporting and auxilliary pad top are V-shaped groove and contour to described transition supporting, pad thin slice pad, alignment pin and crank hole matched in clearance between V-shaped groove and the workpiece on the end face on a left side.
By deciding thimble and live centre is formed axial positioning structure, only revolve in the said structure by the alignment pin that is located on the transition supporting end face.Alignment pin is cut edge up and down with the crank hole section of cooperation and is helped loading and unloading.
The utility model compared with prior art has following good effect:
1, with crank two ends centre bore and crank hole location, rational in infrastructure, simple, the positioning accuracy height;
2, deciding the thimble axial location can regulate, and satisfies different size crank drilling oilhole in the adjustable dimension scope;
But 3 displacement structure charge and discharge operations are easy, the work efficiency height.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the schematic top plan view of Fig. 1.
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.
Positioning and drilling fixture for crank oil hole illustrated in figures 1 and 2, it comprises base 1, transition supporting 2, live centre 3, drill jig frame 4 and decides thimble 5.Described base 1 is a frame structure, and column top up, two ends, the left and right sides is provided with coaxial axially extending bore, and the left end through hole is equipped with axle sleeve 1.1, and the right-hand member through hole is equipped with axle sleeve 5.2, fixedly connected side by side drill jig frame 4 and transition supporting 2 between 1 liang of column of base.Described drill jig frame 4 tops are provided with logical up and down drill bushing 4.1 and make positioning and drilling crank oil hole usefulness.Described transition supporting 2 on the end face on a left side by the alignment pin 2.2 auxilliary pad 2.1 that is located by connecting, transition supporting 2 and auxilliary pad 2.1 tops are V-shaped groove and contour, pad thin slice pad 2.3 between V-shaped groove and the workpiece, alignment pin 2.2 only cooperates with crank hole and revolves, in order to eliminate the influence of the relative axis centre permissible aberration of crank hole, with alignment pin about in the of 2.2 cylindrical wall cut flat.Described live centre 3 stage casings are helical axis, and the guide blot 1.2 that is provided with on this section helical axis and the base 1 left end column fits in the axial screw adjustment structure.Live centre 3 left ends are fixedlyed connected with handwheel 3.2, and right-hand member is a thimble.And decide thimble 5 that thimble relative coaxial with live centre 3 is installed in axle sleeve 5.2 holes, both are matched in clearance, decide to be provided with spring 5.1 between thimble 5 and the right column left side, decide thimble 5 right-hand members connect by bolt 5.5, nut 5.4 and packing ring 5.3 forms with respect to base 1 right column axial adjustment structure, utilize this adjustment structure setting crank oil hole axial location.
During the actual use of the utility model, at first decide the axial location of thimble 5, this position is that datum mark is regulated with the drill bushing in the drill jig frame 4 4.1, put into crank and by deciding thimble 5 axial limitings from left end then, alignment pin 2.2 only cooperates with crank hole and revolves precession live centre 3 supporting crank left end centre bores.Drill bushing 4.1 drillings processing oilhole is pressed in back, crank location.Unscrew live centre and just can take out crank easily.The utility model is with crank two ends centre bore and crank hole location, and is rational in infrastructure, simple, the positioning accuracy height, and drilling is convenient.
