Abstract

It in research material drilling performance, requires to measure the drill thrust and torque of material, but cooperates at present with it without a kind of simple accurately fixture in drilling torgue measurement test.Major design of the present invention a kind of Novel drilling position measured material, the fixture are mainly characterized by: using clamp central as coordinate origin, and being respectively carved with scale and with middle position on slide rail and sliding block for 0 point, be negative, be positive to the right to the left.Drill center axis is converted in the coordinate position of holder coordinate sys by the distance of direct measurement drill center axis to dynamometer limit point, then asks to obtain the distance of each dynamometer limit point by calculating.

Description

A kind of bore-hole position survey fixture
Technical field
The present invention relates to drilling torgue measurement test in, a kind of bore-hole position survey fixture.
Background technique
Currently, in the test of measurement drill thrust and torque, it is most of all to use piezoelectric type dynamometer, but this dynamometry is simultaneously There is no matched bore-hole position survey fixture, so as to the distance no one of drill center axis to each dynamometer limit point The simple accurate measurement method of kind, and largely measured with directlying adopt milimeter scale, measurement point must determine more first Complexity, measurement accuracy is relatively low, and human error is very big;Secondly as length one of the drill center axis to each dynamometer limit point As it is all smaller, therefore, lesser error also can to the measurement of torque generate large effect.In order to improve the measurement of drilling torque Precision devises this fixture convenient for measurement bore position.
Summary of the invention
The technical problems to be solved by the present invention are: being arrived when using dynamometer measurement drilling torque to drill center axis Each dynamometer limit point measurement of length is there are problem, due to dynamometer itself not carrying jig and scale, in measurement drilling When torque, there is no a kind of unified easy accurate measurement method to drill center axis to each dynamometer limit point measurement of length, Especially drill center axis and each dynamometer limit point measures the very difficult of change not in same plane.
In order to solve difficulty existing for drilling torgue measurement, we devise a kind of fixture with coordinate system and scale.It should Clamp structure is as shown in Figure 1.
Firstly, for round piece material due to the self-centering function of fixture, make in test specimen center and holder coordinate sys The heart is overlapped.
Secondly, being not easy to feel relieved for rectangular workpiece, therefore by clamp body coordinate system and its scale, can be easy to Drill center axis is measured in the coordinate (x0, y0) of holder coordinate sys, then acquires drill center axis to each dynamometer by calculating The accurate distance of limit point can measure accurate drilling torque.
Compared with existing test method, the innovative point of this method is: will not be in conplane drill center to each survey The direct measurement of distance is converted into position of the measurement drill center axis in holder coordinate sys between power instrument limit point, then passes through Calculate the accurate distance for obtaining drill center axis to each dynamometer limit point.
Make the measurement of drilling torque become simply, to be easy accurately, while being clamped using two-way lead screw, makes drill center to respectively The distance of dynamometer limit point is more uniform, reduces test measurement error.
The utility model has the advantages that we can be easy to measure drill center axis in holder coordinate sys by the scale on fixture In coordinate position (x0, y0) can be obtained since coordinate origin and each dynamometer limit point distance are determined by calculating Drill center axis can measure accurate drilling torque to the accurate distance of each dynamometer limit point.
Experiment purpose: drilling characteristic and the same material drill thrust under different drilling parameters in order to study different materials The size of square, and be the drilling process of optimization material, it obtains and prepares in optimal drilling parameter, be reasonable employment cutter, reduce Processing cost finally realizes energy-saving and emission-reduction.
Detailed description of the invention
Fig. 1 is the top view of present example.
Fig. 2 is left view.
Fig. 3 cramping body.
In figure: 1 is sliding block, and 2 be two-way lead screw, and 3 be bearing (ball) cover, and 4 be slide rail, and 5 be cramping body, and 6 be millimeter mark Ruler, 7 be clamping fixture seat, and 8 be rolling bearing.
Specific embodiment
Before carrying out drilling torgue measurement test, firstly, by the center of holder coordinate sys centralized positioning to dynamometer, and make It is secured fixtures on dynamometer with bolt.
Second, it determines the shape of workpiece material, cramping body 5 is selected according to shape, and will be in the inserting to sliding block of cramping body 5.
Test specimen is placed among fixture on transverse slat by third, by rotating two-way lead screw for Workpiece clamping.
4th, when cutter positioning, by the scale 6 on fixture, determine position of the drill center axis in holder coordinate sys (i.e. coordinate value (x0, y0)).
Finally, obtaining the length of each arm of force by calculating: for round piece material due to the automatic sizing function of fixture Test specimen center can be made to be overlapped with holder coordinate sys center;Rectangular workpiece is not easy to feel relieved, therefore passes through clamp body coordinate System and its scale, can be easy to measure drill center axis in the coordinate (x0, y0) of holder coordinate sys.
Since coordinate origin and each dynamometer limit point distance determine, drill center axis can be obtained by calculating and arrived The accurate true distance of each dynamometer limit point, can measure accurate drilling torque.
