Description

Ultra-deep blind hole depth measurement apparatus
Technical field
The present invention relates to a kind of hole depth measurement device, more particularly to a kind of depth measurement device of ultra-deep blind hole.
Background technology
When detecting ultra-deep blind-hole parts, when especially hole depth is more than 1.5 meters, the detection of blind hole depth is extremely difficult, And the range of the depth gage of 0.05 millimeter of common precision, because when range is more than 1.5 meters, blocks typically not over 1.5 meters The factors such as the rigidity of chi itself, weight, can have a strong impact on the measurement accuracy of slide calliper rule, and manufacture can be extremely difficult.It is existing measurable The measurer of depth blind hole can only use tape measure, and the measurement accuracy of tape measure is more than 1 millimeter, mechanical when measurement accuracy requires higher When the hole depth processed is more than 1.5 meters, depth detection sample post is typically processed, can only be that accordance is examined with sample post detection, no The specific numerical value of part blind hole depth can be provided.
The content of the invention
The invention provides a kind of ultra-deep blind hole depth measurement apparatus, solves the skill of the accurate measurement of ultra-deep blind hole depth Art problem.
The present invention is that solve above technical problem by the following technical programs:
A kind of ultra-deep blind hole depth measurement apparatus, including workpiece, are provided with ultra-deep blind hole on workpiece, in the aperture of ultra-deep blind hole On be provided with rod support, square shape framework is provided with rod support, adjustable rule bar is movably set with square shape framework, in activity Steel band is provided with chi bar, the rotary encoder of carrying magnetic roller, the rotation of carrying magnetic roller are provided with square shape framework The magnetic rollers of encoder are together with the steel band apical grafting set on adjustable rule bar.
Dynamic chi gauge head is provided with the lower end of adjustable rule bar;The precision of the rotary encoder of carrying magnetic roller is 0.01 milli Rice.
The present invention uses the rotary encoder pattern of carrying magnetic roller, and measurement accuracy will not be long and impacted because of blade, phase Compare the digital display such as grating, capacitive grating mechanism, have than grating digital readout mechanism lower cost and the requirement of lower use environment, specific volume There is longer range in grid digital display mechanism.The measurement accuracy of the present invention exceedes general vernier depth gauge precision, precision up to 0.01 in the least Rice, is particularly suitable for the measurement to ultra-deep blind hole depth.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
The present invention is described in detail below in conjunction with the accompanying drawings:
A kind of ultra-deep blind hole depth measurement apparatus, including workpiece 7, are provided with ultra-deep blind hole 8 on workpiece 7, in ultra-deep blind hole 8 Rod support 1 is provided with aperture, square shape framework 5 is provided with rod support 1, adjustable rule is movably set with square shape framework 5 Bar 2, steel band 3 is provided with adjustable rule bar 2, the rotary encoder 4 of carrying magnetic roller, band are provided with square shape framework 5 The magnetic rollers of the rotary encoder 4 of magnetic rollers are together with the apical grafting of steel band 3 set on adjustable rule bar 2, carrying magnetic roller Rotary encoder 4 magnetic rollers and adjustable rule bar 2 on the steel band 3 that sets carry out PURE ROLLING.
Dynamic chi gauge head 6 is provided with the lower end of adjustable rule bar 2.In view of weight and strength and stiffness, rod support 1 and adjustable rule Bar 2 is made of titanium alloy material.Detect 2 meters or so depth blind holes when, length of movable blade itself at 2300 millimeters, so Movable blade is made using titanium alloy rectangular tube.It is that stainless steel moves chi gauge head that blade bottom, which is equipped with dynamic chi gauge head 6,.Detect hole depth When, rod support 1 is placed on the platform on aperture first, the stainless steel gauge head on adjustable rule bar 2 aligns with the lower plane of rod support 1, Press the clearing on the rotary encoder 4 of carrying magnetic roller(ZERO)Button, the display numerical value on digital display panel is reset.Finally Deep hole size is measured on the basis of the stationary plane on rod support 1.Steel band 3 is with square shape framework 5 of the adjustable rule bar 2 on rod support 1 Rail groove in move.Magnetic rollers in the rotary encoder 4 of carrying magnetic roller make pure rolling on steel band 3, encoder with Rotation counting, and by the straight-line displacement presentation of information that movable blade moves to display panel.
The general difficulty for restricting wide range test measuring device has two aspects, when measurer weight itself and blade rigidity, if Depth gage of the detected size more than 2 meters is made with conventional material, weight is generally 20 kilograms, and insufficient rigidity.The present invention Optimized using titanium alloy material, and in the planform of blade, weight reduces to 11 kilograms or so, and intensity and toughness does not subtract. Second, measurement accuracy, the present invention is avoided using rotary encoder metering straight-line displacement data and is processed scale on overlength blade Error caused by line and difficulty, selected encoder accuracy are 0.01 millimeter, meet the accuracy of detection of ultra-deep blind hole depth It is required that.
