Abstract
The invention relates to a drill jig structure for processing a lower inclined hole of a plunger bushing. The drill jig structure comprises a drill jig body, and a connection mounting plate arranged at the upper part of the drill jig body, wherein a drill bushing is embedded into the mounting plate; a positioning core shaft and a support base are also arranged on the drill jig body; the end part of the support seat is connected with a first positioning pin for embedding a waist hole of the plunger bushing. The drill jig structure is simple in structure, and convenient to install, positioning when the plunger busing is assembled is achieved by using the support seat and the positioning core shaft, the support seat has the positioning function, the positioning reference when the plunger busing is assembled is also effectively ensured, and the drill jig structure is reliable and convenient to process, the stability and the uniformity when the plunger bushing is processed are effectively ensured, time and labor are saved, and the processing efficiency and the production efficiency are improved.
Description
Technical field
The present invention 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 made up 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 two symmetries and be communicated with plunger bushing mesopore at the waist of plunger bushing, 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.
Summary of the invention
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 solution adopted in the present invention 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.
Beneficial effect of the present invention is as follows:
The present invention 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, improve working (machining) efficiency and production efficiency.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, Figure 2 and Figure 3, a kind ofly comprise model drilling body 1 for processing the Drilling Jig Structure of inclined hole under plunger bushing, be positioned in model drilling body 1 and have inclined-plane 101, installing plate 2 is located with model drilling body 1 by the second alignment pin 3, 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 invention 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 completed the processing to lower inclined hole by drill bit being stretched in the boring 601 of drill bushing 6.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification.
