Description
Technical field
The invention belongs to machining technique field, particularly a kind of measurement mechanism for measuring sunk screw height of conical surface.
Background technology
At machinery industry, sunk screw height of conical surface size directly affects the assembling of product, and in traditional processing, the normal calliper etc. that adopts compares and measures to judge that whether it is qualified.And for some significant points for specific occasion and purposes, this is inadequate.Therefore, need to use a kind of measurement mechanism directly can measuring conical surface position height.
Summary of the invention
For overcoming above-mentioned defect, the object of the present invention is to provide a kind of measurement mechanism of energy direct-detection sunk screw height of conical surface size.
For measuring a measurement mechanism for sunk screw height of conical surface, this measurement mechanism comprises: the imaginary diameter of dial gauge, fixed cover, dial gauge gib screw, spring, backing plate, gauge head, measurement inner sleeve, sunk screw head conical surface theory, measurement sleeve; Described dial gauge is positioned at the top of whole measurement mechanism, is fixed in the endoporus of fixed cover by dial gauge gib screw; Fixed cover is sleeved on to be measured on inner sleeve, and inner sleeve end face is fixedly connected with measurement sleeve; Described backing plate is in the inner chamber between the imperial palace nose end and gauge head of fixed cover; The groove for fixing spring is provided with in the upper surface of backing plate; Described gauge head is positioned at the through hole measuring inner sleeve, and can slide up and down in through hole; Measuring sleeve and be positioned at whole device bottom, which is provided with through hole, for placing sunk screw to be measured;
This measurement mechanism is the design base point using the imaginary diameter of sunk screw head conical surface theory as measurement mechanism, after the angle of sunk screw inner conical surface first to be measured is qualified after testing, by gauge head and the relative displacement of measuring inner sleeve, carry out the measurement of imaginary diameter to the position dimension of sunk screw end face of sunk screw head conical surface theory, from dial gauge, directly read the size of screw height of conical surface.
Measurement mechanism of the present invention not only structure is simple, easy to operate, and main is solve traditional measurement trouble and inaccurate defect, substantially increases reliability and the precision of aerospace field part, also reduces production cost simultaneously, improve production efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of measurement mechanism of the present invention.
Shown in figure: the imaginary diameter 9-that 1-dial gauge 2-fixed cover 3-dial gauge gib screw 4-spring 5-backing plate 6-gauge head 7-measures inner sleeve 8-sunk screw head conical surface theory measures sleeve 10-sunk screw to be measured.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
As shown in Figure 1, for a measurement mechanism for sunk screw height of conical surface, this device comprises: the imaginary diameter 8 of dial gauge 1, fixed cover 2, dial gauge gib screw 3, spring 4, backing plate 5, gauge head 6, measurement inner sleeve 7, sunk screw head conical surface theory, measurement sleeve 9, sunk screw to be measured 10.Dial gauge 1 is positioned at the top of whole measurement mechanism, is fixed in the endoporus of fixed cover 2 by dial gauge gib screw 3.Fixed cover 2 is sleeved on to be measured on inner sleeve 7, measures inner sleeve 7 end face and is fixedly connected with measurement sleeve 9.Backing plate 5 is in the inner chamber between the imperial palace nose end and gauge head 6 of fixed cover 2.The groove for fixing spring 4 is provided with in the upper surface of backing plate 5.Gauge head 6 is positioned at the through hole measuring inner sleeve 7, can slide up and down in through hole.Measuring sleeve 9 and be positioned at whole device bottom, which is provided with through hole, for placing sunk screw 10 to be measured.
The present invention is the design base point using the imaginary diameter 8 of sunk screw head conical surface theory as measurement mechanism, by gauge head 6 and the relative displacement of measuring inner sleeve 7, directly reads the size of screw height of conical surface from dial gauge 1.
The calibrating mode of this measurement mechanism is in the upper plane measuring sleeve 9, the end face of measurement mechanism fixed cover 2 resets with the planes align measuring sleeve 9 under the effect of spring 4 with the upper plane and gauge head 6 measuring sleeve 9, using the zero point of this position as measurement mechanism.
After the angle of sunk screw inner conical surface first to be measured is qualified after testing, carry out the P value measurement of imaginary diameter 8 to the position dimension of sunk screw end face of sunk screw head conical surface theory.Before measurement, first clean measurement mechanism, then with dull and stereotyped, dial gauge in measurement mechanism is reset.During measurement, 1) clean piece surface; 2) sunk screw 10 to be measured is contained on the measurement sleeve 9 of dimension; 3) fixed cover 2 end face of measurement mechanism is close to the end face measuring sleeve 9, by the pressure of spring 4, gauge head 6 end face and sunk screw to be measured 10 end face is close to; 3) directly P value is read from dial gauge.
Adopt the advantage of measurement mechanism of the present invention as follows:
Because the measuring basis position of the sunk screw conical surface is in the interruption of the conical surface, conventional measuring method cannot carry out direct-detection to it.Compared with the prior art, this measurement mechanism can be measured by the direct height of conical surface size P to sunk screw fast, directly reads the size of P value; Meanwhile, this measurement mechanism highly versatile, can measure the height of the various angle sunk screw conical surface.This measurement mechanism structure is simple, it is simple to make, and cost is low, measure convenient, testing result is accurate, implementation result is safe and reliable, effectively can solve the problem of P dimensional measurement.Effectively can improve Detection job and the speed of product simultaneously, reduce costs, improve quality and the economic benefit of product.
