Abstract
The utility model relates to a fixture for drilling an excavator caterpillar band gasket. The fixture for drilling the excavator caterpillar band gasket is characterized by comprising a positioning disc, wherein a groove for placing a drill die is arranged in the center of the positioning disc, and a gasket fastening mechanism is arranged on the positioning disc; and the gasket fastening mechanism comprises a shaft bracket fixedly connected with the positioning disc, the shaft bracket is provided with a camshaft in a movable and matched mode, the camshaft is provided with a cam through a fastening screw, and one end of the camshaft is in threaded connection with a handle of the cam. The fixture for drilling the excavator caterpillar band gasket has the advantages that the cam is matched with a pressing plate, the drill die below the other end of the pressing plate and a gasket below the other end of the pressing plate are tightly pressed on the positioning disc, the plane of the gasket is tightly attached to the surface of the positioning disc so as to ensure that a drilled hole is perpendicular to a positioning surface and the drilled hole can not loosen in the drilling process. The fixture for drilling the excavator caterpillar band gasket is time-saving and labor-saving when the gasket (a workpiece) is machined, and reliable and efficient in drilling.
Description
Technical field
The utility model belongs to machining and uses the clamp technology field, particularly relates to a kind of excavator crawler belt pad part drilling anchor clamps.
Background technology
Traditional excavator crawler belt pad part is when two holes of drilling on it, generally be to adopt scroll chuck to clamp the drill jig cylindrical, bowlder outside scroll chuck clamps drill jig can't guarantee the parallel of pad plane and chuck plane, causes the scroll chuck clamping force not act on the pad as yet.After having bored first hole, operating personnel need pack in this hole behind the alignment pin, can bore second hole, and so not only its form and position tolerance is undesirable, influences the qualification rate of pad, and the drilling working (machining) efficiency is lower.
Summary of the invention
The utility model guarantees anchor clamps and pad clamping, accurate positioning for the technical problem that exists in the solution known technology provides a kind of, is convenient to adjust and can improve the excavator crawler belt pad drilling anchor clamps of working (machining) efficiency.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Excavator crawler belt pad drilling anchor clamps comprise positioning disk, and described positioning disk center is shaped on for the groove of placing drill jig, is provided with the pad retention mechanism at described positioning disk.
The utility model can also adopt following technical scheme:
Described pad retention mechanism comprises: the pedestal affixed with described positioning disk, and described pedestal is equipped with camshaft movingly, and described camshaft is equipped with cam by trip bolt, connects cam handle at the camshaft threaded one end.
Described pad retention mechanism also comprises the pressing plate that an end contacts with cam, and the described pressing plate other end is shaped on spherical gib head, and spherical gib head is pressed in the drill jig center.
Described pressing plate is coated with support bar near medium position, is set with the pressing plate support spring on the described support bar, and described support bar one end is threaded with positioning disk.
Described positioning disk one side is connected with the positioning disk handle.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, be that these anchor clamps are by action of cam power jack-up pressing plate, because the active force (fulcrum is at the support bar center) of lever makes drill jig and the pad (workpiece) below the pressing plate other end tightly be pressed on the positioning disk, tightly fit in pad plane and positioning disk surface, make by the hole of drilling vertically with locating surface, in drilling process, can not become flexible.The revolution of described cam handle outer end employing ARTIFICIAL FORCE drags camshaft and cam rotates together, when cam holds out against pressing plate, utilizes the lever moment principle to alleviate artificial drawing force.Adopt these anchor clamps drilling processing pad (workpiece) time saving and energy saving, the boring location is reliable, efficient is high.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A cutaway view of Fig. 1.
Among the figure: 1, positioning disk; 2, cam handle; 3, camshaft; 4, pedestal; 5, cam; 6, circlip; 7, pressing plate; 7-1, spherical gib head; 8, support bar; 9, pad (workpiece); 10, drill jig; 11, positioning disk handle; 12, pressing plate support spring; 13, trip bolt; 14, spheric washer.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, excavator crawler belt pad drilling anchor clamps comprise positioning disk 1, and described positioning disk center is shaped on for the groove of placing drill jig 10, is provided with the pad retention mechanism at described positioning disk.Described pad retention mechanism comprises: the pedestal 4 affixed with described positioning disk 1, described pedestal is equipped with camshaft 3 movingly, camshaft is free to rotate, described camshaft is equipped with cam 5 by trip bolt 13, be positioned on the camshaft in the pedestal outside and be connected with circlip 6, to realize the axial location of cam and pedestal, described camshaft threaded one end connects cam handle 2.
Described pad retention mechanism also comprises the pressing plate 7 that an end contacts with cam, and the described pressing plate other end is shaped on spherical gib head 7-1, and described spherical gib head is pressed in the drill jig center.
Described pressing plate 7 is coated with support bar 8 near medium position, is set with pressing plate support spring 12 on the described support bar, in the space of described pressing plate support spring between pressing plate and positioning disk.Described support bar lower end is threaded with positioning disk, and post upper passes pressing plate and spheric washer 14 is housed.
Described positioning disk one side is connected with positioning disk handle 11, can manually drag the position of positioning disk by the positioning disk handle.
These anchor clamps are to be a kind of anchor clamps of excavator crawler belt pad workpiece drilling processing design, and it is that cam outer face center line and cam inner hole centreline depart from that the center line of camshaft and the center line of cam surface depart from 3mm().When rotating cam, cam can hold out against the pressing plate right-hand member, makes the spherical gib head of pressing plate left end compress drill jig and pad (workpiece), and then has guaranteed that the pad plane is parallel with the positioning disk bottom surface.Because the positioning disk in work piece and the anchor clamps all is in the horizontal plane state, so the hole that processes is perpendicular to surface of the work.In addition, support bar is threaded with positioning disk, pressing plate can be adjusted up and down namely satisfied the different thickness requirement of pad (workpiece).
Operation principle of the present utility model is as follows:
Operating personnel manually are rotated counterclockwise cam handle 2, and camshaft 3 is rotated counterclockwise with cam 5, when pressing plate 7 compresses drill jig 10 with pad 9, and cam stop motion and self-locking.But two holes in the drilling pad then, after boring is finished, operating personnel's cam handle that manually turns clockwise again, make pressing plate leave drill jig, take drill jig and pad then away, change next pad and put into drill jig and put into the positioning disk groove together, the processing of next time holing.
