Abstract
The utility model relates to a drill jig structure for processing lower inclined holes in plunger sleeves. The drill jig structure for processing the lower inclined holes in the plunger sleeves comprises a drill jig body, wherein the upper portion of the drill jig body is connected with an installation plate, a drill jig bushing is embedded in the installation plate, a positioning core shaft and a supporting seat are arranged on the drill jig body, and a first positioning pin embedded into a plunger bushing waist-shaped hole is connected with the end of the supporting seat. The drill jig structure for processing the lower inclined holes in the plunger sleeves is simple in structure and convenient to install, uses the supporting seat and the positioning core shaft to achieve positioning of the plunger bushing during the assembly process, further effectively guarantees the locating basis of the plunger bushing during the assembly process due to the fact that the supporting seat has a locating function, is reliable and convenient in processing, effectively guarantees stability and uniformity of the plunger bushing when the plunger bushing is processed, saves time and labor, and improves processing efficiency and production efficiency.
Description
Technical field
The utility model relates to process equipment, especially a kind of for processing the Drilling Jig Structure of inclined hole under plunger bushing.
Background technology
Plunger matching parts is formed by plunger and plunger bushing precision-fit, delivery valve matching parts (being comprised of delivery valve and delivery valve seat) is equipped with in its top, plunger can be divided into A type, Type B, K type, AD type, P type etc. by its applicable injection pump difference, to meet the demand of different diesel engines.At present, according to product drawing requirement, the lower inclined hole that need to process at the waist of plunger bushing two symmetries and be communicated with plunger bushing mesopore, because lower inclined hole tilts at an angle, processing request is higher, difficulty is larger, so a kind of for processing the Drilling Jig Structure of inclined hole under plunger bushing in the urgent need to designing.
Utility model content
The applicant, for above-mentioned existing issue, is studied improvement, provides a kind of and has effectively realized the processing of inclined hole under plunger bushing in enormous quantities for processing the Drilling Jig Structure of inclined hole under plunger bushing, has improved production efficiency.
The technical scheme that the utility model adopts is as follows:
For processing a Drilling Jig Structure for inclined hole under plunger bushing, comprise model drilling body, the top that is positioned at described model drilling body is connected and installed plate, and drill bushing is embedded in described installing plate; Be positioned in described model drilling body, returning apparatus positioning core axle and supporting base, the end that is positioned at described supporting base connects for rabbeting the first alignment pin of plunger bushing mounting hole.
Its further technical scheme is:
Be positioned in described model drilling body and have inclined-plane, one end of described positioning core axle is run through described model drilling body and is connected by locking nut;
One end of described supporting base is stretched into described model drilling body and is fixed by lock-screw;
Described supporting base is kidney-shaped, has the locating surface for plunger bushing butt on described supporting base.
The beneficial effects of the utility model are as follows:
The utility model is simple in structure, easy for installation, utilize supporting base and positioning core axle to realize location when plunger bushing is assembled, supporting base has positioning function, positioning datum while also effectively having guaranteed plunger bushing assembling, processing is reliably convenient, has effectively guaranteed that plunger bushing adds the stability in man-hour, uniformity, time saving and energy saving, improved working (machining) efficiency and production efficiency.

Wherein: 1, model drilling body; 101, inclined-plane; 102, locking nut; 2, installing plate; 3, the second alignment pin; 4, hold-down screw; 5, the first lock-screw; 6, drill bushing; 7, lining; 8, plunger bushing; 801, mounting hole; 9, positioning core axle; 10, the first alignment pin; 11, supporting base; 1101, locating surface; 12, the second lock-screw.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Figure 1, Figure 2 and Figure 3, a kind ofly for processing the Drilling Jig Structure of inclined hole under plunger bushing, comprise model drilling body 1, be positioned at and in model drilling body 1, have inclined-plane 101, installing plate 2 is by the second alignment pin 3 and model drilling body 1 location, and realizes fixing by hold-down screw 4.Drill bushing 6 is embedded in installing plate 2 by lining 7, and fixing by the first lock-screw 5.Be positioned in model drilling body 1, returning apparatus positioning core axle 9 and supporting base 11, model drilling body 1 fixing by the second lock-screw 12 is stretched in one end of supporting base 11.Supporting base 11 is kidney-shaped, has the locating surface 1101 for plunger bushing 8 butts on supporting base 11.The other end that is positioned at supporting base 11 connects for rabbeting the first alignment pin 10 of plunger bushing 8 mounting holes 801, and as shown in Figure 3, the first alignment pin 10 is rhombus.As shown in Figure 1, one end of positioning core axle 9 is run through model drilling body 1 and is connected by locking nut 102.
Specific works process of the present utility model is as follows:
As shown in Figure 1, first the mesopore of plunger bushing 8 is matched with positioning core axle 9, then the angle of adjustment column plug sleeve 8, the mounting hole 801 of plunger bushing 8 is matched with the first alignment pin 10, a side of plunger bushing 8 and the locating surface 1101 of supporting base 11 match simultaneously, complete thus the origin reference location to plunger bushing 8, then by drill bit being stretched in the boring 601 of drill bushing 6, completed the processing to lower inclined hole.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
