Abstract
The invention discloses a fixture for an inclined oil hole of a cylinder body and relates to the technical field of manufacturing of machining equipment. The fixture comprises a base, an inclined supporting seat is arranged in the front of the base, an inclined plane supporting seat is arranged at the rear of the base, and drill jig supporting seats are both arranged on two side faces of the base between the inclined supporting seat and the inclined plane supporting seat. Drill jig supporting blocks are arranged at upper ends of the drill jig supporting seats, drill jigs are arranged on the drill jig support blocks, and two ends of the drill jigs are connected with the drill jig supporting seats. A transition plate is arranged on the inclined plane supporting seat and is provided with a positioning hole for positioning pins to position a workpiece to be processed, and a center line of the inclined plane supporting seat and vertical center lines of the drill jig supporting seats form an included angle of 41.04 degrees. By the aid of the fixture, problems of large position error and time and energy wasting during model changing production when a drill inclined oil passage hole is processed can be solved.
Description
Technical field
The present invention relates to machining equipment manufacturing technology field, especially a kind of cylinder body inclined oil hole of air fixture of using for boring the oblique oil hole of crankcase.
Background technology
Crankcase was being added to man-hour in the past, on the inclined-plane bearing of cylinder body inclined oil hole of air fixture, be provided with two circular holes corresponding with the cylinder hole of the 1st cylinder and the 4th cylinder as shown in Figure 1, Figure 2 with shown in Fig. 5; To boring oblique oil hole, adding man-hour, is that the cylinder hole with the 1st cylinder and the 4th cylinder positions, and such location exists following shortcoming: fine finishining is not also carried out in (1) cylinder hole, and semi-finished Aperture deviation is larger, causes its position error large; (2) crankcase of different model is remodeled while producing, and because the size in cylinder hole is different, need to change alignment pin.So inconvenient when remodeling production, waste time and energy.
Summary of the invention
The object of this invention is to provide a kind of cylinder body inclined oil hole of air fixture, it can solve and add man-hour to boring oblique oil hole, and position error is large, the problem of remodeling and wasting time and energy while producing.
In order to address the above problem, the technical solution used in the present invention is: this cylinder body inclined oil hole of air fixture, comprise base, in the front portion of described base, be provided with oblique supporting base, at its rear portion, be provided with inclined-plane bearing, the two sides of the described base between described oblique supporting base and described inclined-plane bearing are equipped with drill jig bearing; In the upper end of described drill jig bearing, be provided with drill jig rest pad, on this drill jig rest pad, be provided with drill jig, these drill jig two ends are connected with described drill jig bearing; On described inclined-plane bearing, be provided with rebound, this rebound is provided with the locating hole for the alignment pin of to be processed location, and the center line of described inclined-plane bearing becomes the 41 degree angle of 4 minutes with the vertical center line of described drill jig bearing.
In such scheme, more specifically scheme can also be: on described oblique supporting base 2, be provided with oblique support strip 4.
Further: on described inclined-plane bearing, be also provided with support strip.
Owing to having adopted technique scheme, the present invention compared with prior art, the beneficial effect having is: owing to adopting dowel hole to position, and the operation of the dowel hole of crankcase end face has above been worked into finished size, and the size of the end face dowel hole of each model crankcase of producing is at present consistent, so, positioning precision improved, guarantee the stability of crudy, convenient, quick when remodeling production.
Accompanying drawing explanation
Fig. 1 is that structure of the present invention is faced cross-sectional schematic.
Fig. 2 is that cross-sectional schematic is looked on a left side of Fig. 1.
Fig. 3 is that the middle A of Fig. 1 is to view.
Fig. 4 is that the B of Fig. 1 is to view.
Fig. 5 is that the B of prior art is to view.
The specific embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
Cylinder body inclined oil hole of air fixture shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, oblique supporting base 2 is fixed by bolts to the front portion of base 1, on the inclined-plane of oblique supporting base 2, with bolt, is fixed with oblique support strip 4; At the rear portion of base 1, be fixed with inclined-plane bearing 13, on inclined-plane bearing 13, be provided with support strip 7; The two sides of the base 1 between oblique supporting base 2 and inclined-plane bearing 13 are equipped with drill jig bearing 3; In the upper end of drill jig bearing 3, be provided with drill jig rest pad 8, on this drill jig rest pad 8, be provided with drill jig 11, these drill jig 11 two ends are connected with drill jig bearing 3 with alignment pin; On inclined-plane bearing 13, be provided with rebound 6, on this rebound 6, be provided with support strip 7, rebound 6 is provided with the locating hole for the alignment pin 5 of to be processed location, and the center line of inclined-plane bearing 13 becomes the 41 degree angle of 4 minutes with the vertical center line of drill jig bearing 3.
When work, crankcase to be processed is placed on the inclined-plane bearing 13 between two drill jig bearings 3, oblique support strip 4 on oblique supporting base 2 is withstood this crankcase to prevent that this crankcase from toppling over, with alignment pin 5, the locating hole of the dowel hole of crankcase end face and inclined-plane bearing 13 is connected and fixed, thereby crankcase is fixed in this fixture.When boring oblique oil hole, because having drill jig bearing 3, the crankcase left and right sides clamps, and its bottom is fixed on inclined-plane bearing 13 with alignment pin, direction in its inclination has oblique support strip 4 to withstand, so when boring oblique oil hole, crankcase can not move, guaranteed the precision of processing.
