The utility model content
The purpose of the utility model is exactly to solve the problems referred to above that exist in the prior art; Provide a kind of gauging machine to detect anchor clamps, on gauging machine, use these anchor clamps, under the prerequisite that does not change the original performance of gauging machine with indicating gauge; Realization realizes the function of a tractor serves several purposes to the calibrating or the calibration of indicating gauge.
For realizing above-mentioned purpose, the technical solution of the utility model is: a kind of gauging machine detects anchor clamps with indicating gauge, and it comprises base, cushion block and gauge head holder that the track of bottom surface and gauging machine is complementary; Have screw on the base side wall, it is fixedly clamped on the orbit sidewall of gauging machine by clamping screw; Have concentric screw on base, cushion block and the gauge head holder, it is worn by long spiro nail and fastens; Gauge head holder upper end laterally has instrument bar hole, and its upper surface has the screw that is connected with instrument bar hole, and clamping screw is installed in the screw.
After on the track of gauging machine the utility model being installed; 0.01mm indicating gauge, 0.02mm indicating gauge, 0.002mm clock gauge, part digital display meter can directly be examined and determine or calibrate; Through comparing, can also examine and determine or calibrate instrument such as all the other indicating gauges, torsion spring table, all the other digital display meters, dial type displacement transducer indirectly with corresponding gauge block.Make gauging machine not only can realize high-acruracy survey to the product fixed measure; Can be widely used in China's vertification regulation listed the indicating gauge calibrating or the calibration that comprise specifications such as other type indicating gauge, torsion spring table, long range dial gage again; Can examine and determine micrometer gauge, table made in Great Britain and digital display meter etc.; Also can examine and determine instrument and the workpiece of stroke, realize the function of a tractor serves several purposes less than any special requirement compression size of 100mm.It can realize the calibrating or the calibration of the indicating gauge of the above precision of 0.5 μ m, and calibrating or calibration accuracy are high, the wide ranges of calibrating or calibrated meter, and universal strong, simple to operate.The installation of the utility model makes gauging machine realize the function of a tractor serves several purposes, can be enterprise and saves substantial contribution, saves breadboard taking up room, for enterprise brings huge profit margin.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further description.
Like Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, present embodiment comprises base 2, cushion block 7 and the gauge head holder 3 that the track of bottom surface 8 and gauging machine is complementary.Have screw on base 2 sidewalls, it is fixedly clamped on the orbit sidewall of gauging machine by clamping screw 1.Have concentric screw on base 2, cushion block 7 and the gauge head holder 3, it is worn by long spiro nail 6 and fastens.Gauge head holder 3 upper ends laterally have instrument bar hole 5, and its upper surface has the screw 12 that is connected with instrument bar hole 5, and clamping screw 4 is installed in the screw 12.9 is the concentric screw that has on the cushion block 7, and 10 is the concentric screw that has on the gauge head holder 3.
Be example with calibrating or calibration clock gauge (scale division value is 0.002mm, and the error of indication requires to be no more than 7 μ m) below, specifically introduce the principle of work of this device.
1, installs: a plane survey cap is installed for earlier the measurement thick stick of gauging machine optics meter pipe, the gauging machine tail pipe is aimed at any round values, again the utility model is installed on the gauging machine guide rail; Clock gauge is installed in the instrument bar hole, unclamps clamping screw, left and right sides coarse adjustment base; Make the movable gauge head of clock gauge roughly be positioned at the center of gauging machine gauge head; The fine setting gauging machine makes the gauging machine gauge head contact with the clock gauge gauge head, and the compression measuring staff makes indicating gauge basically to zero.
2, zero-bit is regulated: rotate the trimming hand wheel of gauging machine, with the millimeter rule zero set of gauging machine, simultaneously, with indicating gauge to zero.
3, value testing; By the trimming hand wheel of interval 0.2mm rotation gauging machine, pointwise activity compression gauge head is measured, until total travel.
4, calculate: respectively receiving the maximum of cautious error and the difference of minimum value in the positive stroke is the gamut error of indication of this indicating gauge; The maximal value of the difference of consecutive point is adjacent error in the positive stroke; Maximum difference with minimum value is any section error in the individual pen, and the maximal value of the difference of positive revesal same point error is a hysterisis error.
Calibrating interval＜the 0.1mm of part indicating gauge can survey the gauge block of placing suitable dimension between cap at indicating gauge gauge head and gauging machine, compares and measures, thereby draws calibrating or calibration conclusion.
In order to confirm the degree of reliability of this method, our foundation " the measurement standard examination standard JJF1033-2008 of the People's Republic of China (PRC) " has been done the uncertainty evaluation of this scheme, and evaluation result meets the requirements.
