Description
Technical field
The utility model relates to Machining Technology field, relates in particular to a kind of drill jig.
Background technology
Shaft coupling is a kind of part conventional in plant equipment, and its effect is that the axle of two rotations is linked together.Shaft coupling is generally comprised of two half a couplers, needs to arrange through hole on half a coupler, then a half a coupler is connected with bolt and nut by through hole with another half a coupler.Through hole on half a coupler is generally processed on drilling machine.If small lot batch manufacture, general employing line is rushed sample and is then placed on drilling machine and holes, if produce in enormous quantities, if also adopt this method boring, have following problem, the one, it is very time-consuming that sample is rushed in line, operating efficiency is very low, and the 2nd, it is low that the hole site precision that sample bores is rushed in line.
Utility model content
Problem to be solved in the utility model is, for the defect of prior art, provides a kind of half a coupler drill jig, can increase work efficiency and improve the positional precision in hole.
The purpose of this utility model is achieved through the following technical solutions.A kind of half a coupler drill jig, comprise be arranged on half a coupler upside bushing plate, be arranged on the base of half a coupler downside, bushing plate is provided with for bushing plate being positioned to the location structure on half a coupler, on bushing plate, be also provided with drill bushing hole, drill bushing is provided with drill bushing in hole, is provided with dismountable clamping device between described bushing plate and base.During use, half a coupler is placed on base, and bushing plate is placed on half a coupler, utilizes location structure that bushing plate is accurately located on half a coupler, with clamping device, bushing plate, half a coupler and base are clamped again, then place it on drilling machine and can hole.After a half a coupler drilling part completes, clamping device is unclamped, part takes off, then another half a coupler part is processed by the same method.Adopt this device, need not rule and rush sample, install and dismantle half a coupler conveniently, therefore improved operating efficiency, and because having adopted location structure location, therefore improved positioning precision, thereby improved the positional precision in hole.
As preferably, described bushing plate is circular configuration, and the center of bushing plate is provided with the through hole of a circle, and described location structure comprises the circle bulge loop arranging along the edge of bushing plate circle, and the U-shaped groove arranging on the circumference of through hole.Half a coupler is a circular configuration, and there is a manhole at center, has a U-shaped groove on the circumference of manhole.During use, the bulge loop of bushing plate is enclosed within on half a coupler, the U-shaped groove on bushing plate is alignd with the U-shaped groove on half a coupler, bushing plate can be positioned on half a coupler exactly, accurate positioning, the positional precision of boring is high.This location structure is simple, easy to use.
As preferably, described clamping device comprises C shape pad and stud, and C shape pad is arranged on the upside of bushing plate, and stud is through C shape pad, bushing plate, half a coupler and base, and fastening nuts is used respectively at the two ends of stud.This clamping device is simple in structure, easy to operate.
As preferably, described drill bushing hole is circular configuration, and the circumference in drill bushing hole is provided with some semi-circular recesses.Between drill bushing and drill bushing hole, be interference fit, drill bushing produces wearing and tearing after using a period of time, drill bushing must be taken out from the drill bushing hole of bushing plate, because be interference fit, during taking-up, frictional force is very large, is difficult to take out.Semi-circular recesses is set, has reduced the contact area between drill bushing and bushing plate, thereby reduced frictional force, be easy to operate, improved operating efficiency.
Main beneficial effect of the present utility model is, improved operating efficiency, improved the hole site precision of half a coupler.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the structural representation of bushing plate.
Fig. 3 is the cutaway view of Fig. 2.
The specific embodiment
Below the utility model is described in further detail in conjunction with the accompanying drawings and embodiments:
As shown in Figure 1 to Figure 3, a kind of half a coupler drill jig, comprise the bushing plate 5 that is arranged on half a coupler 6 upsides, be arranged on the base 7 of half a coupler downside, bushing plate is circular configuration, the center of bushing plate is provided with the through hole 52 of a circle, bushing plate is provided with 6 drill bushing holes 51, drill bushing hole is circular configuration, the circumference in drill bushing hole is provided with four uniform semi-circular recesses 511, 6 drill bushing holes are positioned on same circumference, in each drill bushing hole, be provided with drill bushing 1, bushing plate is provided with for bushing plate being positioned to the location structure on half a coupler, location structure comprises the circle bulge loop 53 arranging along the edge of bushing plate circle, and the U-shaped groove arranging on the circumference of through hole 52.Between described bushing plate and base, be provided with dismountable clamping device, clamping device comprises C shape pad 2 and stud 3, C shape pad is arranged on the upside of bushing plate, stud is through C shape pad, bushing plate, half a coupler and base, the two ends of stud use respectively fastening nuts 4 and fastening nuts 8 fastening.
During use, half a coupler is placed on base, bushing plate is placed on half a coupler, bulge loop circle is lived half a coupler, U-shaped groove on bushing plate aligns with the U-shaped groove on half a coupler, C shape pad is arranged on the upside of bushing plate, and stud is through C shape pad, bushing plate, half a coupler and base, the two ends of stud use respectively fastening nuts 4 and fastening nuts 8 fastening.Then place it on drilling machine and can hole.After a half a coupler drilling part completes, clamping device is unclamped, part takes off, then another half a coupler part is processed by the same method.Adopt this device, need not rule and rush sample, install and dismantle half a coupler conveniently, therefore improved operating efficiency, and adopted location structure location, therefore improved positioning precision, thereby also improved the positional precision in hole.
The above is the preferably specific embodiment of the utility model, not with this, limits practical range of the present utility model.The utility model can also have other embodiment, only otherwise deviate from spirit of the present utility model, and within no matter in form what kind of conversion all drops on protection domain of the present utility model.
