Application number is the technical scheme that 200810195432.7 invention adopts: a kind of drill jig, it comprises: base, be fixed on base top gripper shoe, be rotationally connected with angle control rotating disk in gripper shoe, be positioned at four lock holes on angle control rotating disk, four lock holes lay respectively at diagonal become special angle rectangular four summits, be positioned at the lock(ing) bolt in gripper shoe, coaxially be fixed on the work thick stick on angle control panel, have two rows the be separated by through hole of special angle and the clamp of fixation workpiece on thick stick in work.The problem that this invention solves: 1. can be by above the work that is locked in thick stick stable steel pipe to be processed by the clamp being threaded described in utilizing, add man-hour at workpiece, be not easy to be subjected to displacement, eliminate due to displacement produce bad: be 2. rotationally connected with angle control rotating disk in gripper shoe and lock hole on being positioned at angle control rotating disk and be positioned at together with the lock(ing) bolt at the gripper shoe back side, form the angle controller of this device, thereby can control the angle of rotation.
But in prior art, for the fixture of drilling machine, generally have two problems, the first clamping that can only carry out single is located, is carried out a drilling campaign, and for the part with looping pit, processing is inconvenience very; What the drill jig great majority that the second various machining is used all adopted is hand-operated clamping, and the size of clamping force should not be held, takes time and effort, inefficiency.
Utility model content
In order to address the above problem, the utility model provides a kind of drill jig of valve body drilling.Concrete scheme is as follows:
A kind of drill jig of valve body drilling, comprise that there is spring holder seat base, rotating disk, girder, cylinder, drill bushing seat and inside, it is characterized in that: rotating disk is connected with base by multidiameter, girder, cylinder, drill bushing seat and inside have spring holder seat to be bolted on respectively on base; Girder and cylinder are fixed on base rear side; Location key seat is fixed on chassis left side; Drill bushing seat is fixed on base right side.
On described rotating disk, be provided with lockhole; Location key seat is provided with calibration alignment pin; Calibration alignment pin matches with the lockhole on rotating disk.
Described girder is provided with compression axis, and compression axis below is provided with briquetting.
Described cylinder is connected with compression axis by hinge.
Described girder rear side has also been bolted stiffener.
Described compression axis is provided with cylinder backing pin.
The beneficial effects of the utility model are:
Calibration alignment pin successively with rotating disk on lock hole location, location is accurately convenient, can realize drilling porous.
2. promote compression axis by cylinder and make briquetting clamping work pieces, it is time saving and energy saving to operate, and working (machining) efficiency is high, can realize accurate clamping.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model is further elaborated.
A kind of drill jig of valve body drilling, comprise that there is spring holder seat 2 base 1, rotating disk 3, girder 10, cylinder B14, drill bushing seat 7 and inside, it is characterized in that: rotating disk 3 is connected with base 1 by multidiameter 4, and girder 10, cylinder B14, drill bushing seat 7 and inside have spring holder seat 2 to be bolted on respectively on base 1; Girder 10 and cylinder B14 are fixed on base rear side; Location key seat 2 is fixed on chassis left side; Drill bushing seat 7 is fixed on base right side.
On described rotating disk 3, be provided with lockhole; Location key seat 1 is provided with calibration alignment pin B1; Calibration alignment pin B1 matches with the lockhole on rotating disk 3.
Described girder 10 is provided with compression axis 6, and compression axis 6 belows are provided with briquetting 5.
Described cylinder 4 is connected with compression axis 6 by hinge 9.
Described girder 10 rear sides have also been bolted stiffener 8.
Described compression axis 6 is provided with cylinder backing pin 11.
When the work of this drill jig, rotating disk positions by calibration alignment pin, and part positions by cylinder backing pin and rotating shaft, clamps by cylinder.In location and after clamping and move, carry out drilling first, after drilling completes first, cancel clamping force, alignment pin is pulled up, turntable rotation 90 is spent, again by alignment pin location, Workpiece clamping cuts afterwards for the second time.All the other cutting steps of twice are with identical above.
As shown in Figure 1, a kind of drill jig of valve body drilling comprises base 1, is connected with base by multidiameter 4 rotating disk 3, the girder 10 being connected with base by bolt and cylinder B14, drill bushing 7 and calibration alignment pin B1.Calibration alignment pin B1 first with rotating disk 3 on a lock hole position, then the part of needs processing is placed on multidiameter 4 and with cylinder backing pin and coordinates accurately and locate, then cylinder B14 promotes compression axis 6 and makes briquetting 5 clamping work pieces, after clamping has been moved, carry out drilling first.After drilling completes first, cylinder push-rod declines, and by lever principle, drives hinge 9 to rise, thereby makes compression axis 6 drive briquetting 5 to rise, and reaches the object of cancelling clamping force.After clamping force is cancelled, alignment pin B1 is pulled up, rotating disk 3 is rotated to 90 degree, another lock hole on rotating disk 3 is aimed to alignment pin B1, location, carries out the drilling in second hole again.The drilling process in all the other two holes is identical with the step in second hole.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
