The gauge comprises a reference pin provided with a step at the end, a detection sleeve, a spacer pin, a guide pin bush and a bracket, wherein, the detection sleeve is sheathed on the external surface of the reference pin and capable of sliding on the external surface of the reference pin along the axis; the spacer pin is fixed on the reference pin; the guide pin bush is fixed on the bracket; the front end of the reference pin is fixed on the guide pin bush; and the upper surface of the detection sleeve is theoretically positioned at the midpoint of the upper and lower surfaces of the step. The gauge better solves the problem of the difficult measurement of profile tolerance of some surfaces, achieves very good effect, and greatly reduces the production cost in addition to the practical and effective structure.
Description
Technical field
The utility model relates to the cubing on a kind of measurement products surface, and the facial contour degree that relates in particular to surface with holes in a kind of product detects.
Background technology
The surface characteristics of engineering goods as the facial contour degree, is an important techniques index of product, after formed product, need detect.
At present, the facial contour degree on measurement products surface, more existing mature methods are as (1). and adopt simulated block to measure, because some tested product surface is a upper surface, this simulated block is the top that is positioned at the surface in working order the time, influence product and be installed on the cubing, so it is this simulated block must be made upset or travel mechanism, comparatively complicated, when detecting the surface, also must cooperate and end drift or clearance gauge uses.Use cumbersome, different testing staff when use ends drift or clearance gauge, actual effect also can some little difference.(2). adopt clamp to measure.Same because tested product surface is a upper surface, this clamp is the top that is positioned at the surface in working order the time, influence product and is installed on the cubing, overturns or travel mechanism so this clamp must be made equally, comparatively complexity.When detecting the surface, also must cooperate and end drift or clearance gauge uses.Use cumbersome, different testing staff when use ends drift or clearance gauge, actual effect also can some little difference.(3). adopt three coordinate measuring machine to detect to surface to be measured.Three-dimensional coordinates measurement all than higher, causes the cost that detects very high to instrument, environmental requirement.And, just can't detect this surface there not being the occasion of three coordinate measuring machine.The limitation that this method is used is too big.
Chinese patent application number 01819300.5 and middle number of patent application 200520009316.1 have been reported a kind of member that is used for the testing product surface, but, the technology that above-mentioned patent provides does not have universality, can not be used for the detection of facial contour degree on the surface with holes of engineering goods.
Summary of the invention
The purpose of this utility model provides the device of a kind of measurement products surface facial contour degree, to overcome the above-mentioned defective that prior art exists, satisfies the needs of the parties concerned.
The device of measurement products of the present utility model surface facial contour degree comprises that the upper end is provided with the reference pins of step, detection sleeve, spacer pin, guide and limit cover and support;
Said detection jacket casing is at the outside surface of reference pins, and can slide at the outside surface upper edge of reference pins axis, and spacer pin is fixed on the reference pins, detects the sliding distance of sleeve with restriction, and simultaneously, spacer pin can also prevent to detect separating of sleeve and reference pins;
The guide and limit cover is fixed on the support;
The front end of reference pins and guide and limit cover are the relations of clearance fit, and are fixed on guide and limit by step and put;
The lower surface of detection sleeve contacts with product surface to be detected, and its upper surface is positioned at the centre on the upper and lower surface of step in theory.
The utility model preferably resolves the problem for some surface measurement difficulty, has obtained extraordinary effect, not only structure practicality, effective, and greatly reduce production cost.Neither need to make complicated upset or travel mechanism, need be by means of three coordinate measuring machine yet.

Embodiment
Referring to Fig. 1 and Fig. 2, the throw-over gear of measurement products of the present utility model surface facial contour degree comprises that the end is provided with the reference pins 1 of step 6, detection sleeve 2, spacer pin 3, guide and limit cover 4 and support 5;
Said detection sleeve 2 is enclosed within the outside surface of reference pins 1, and can slide at the outside surface upper edge of reference pins 1 axis;
Spacer pin 3 is fixed on the reference pins 1, detects the sliding distance of sleeve 2 with restriction, and simultaneously, spacer pin 3 can also prevent to detect separating of sleeve 2 and reference pins 1;
Guide and limit cover 4 is fixed on the support 5, and the front end of reference pins 1 and guide and limit cover 4 are relations of clearance fit, and is fixed on the guide and limit cover 4 by step;
The lower surface of detection sleeve 2 contacts with product surface to be detected, and its upper surface is positioned at the centre on step 6 upper and lower surfaces in theory;
Wherein, reference pins 1 is relations of clearance fit with detecting sleeve 2, and spacer pin 3 is the relation of interference fit with reference pins 1, and reference pins 1 is relations of clearance fit with guide and limit cover 4, and guide and limit cover 4 is relations of interference fit with support 5.
Said detection sleeve 2 is generally cylinder, if the bore dia of this surface to be measured is d, the outer end diameter that then detects sleeve 2 and product surface contact portion is d+10～d+15mm (considering the size of surf zone to be detected simultaneously);
Said reference pins 1 is generally cylinder, and its diameter by product surface holes to be measured place is d-2mm, and it is d+2mm with the diameter that detects sleeve 2 cooperation places;
The height H of said step 6 equals the facial contour number of degrees value on test product surface, as: the facial contour degree of measured surface is 1mm, and then step 6 height H also are 1mm.
Term " facial contour degree " has detailed definition on mechanical design handbook.
The utility model is to use like this:
To detect sleeve 2 and be inserted in reference pins 1, insert spacer pin 3, reference pins 1 and detection sleeve 2 will be fitted together, stop collar 4 will be fixed on the said support 5.Then with the hole of reference pins 1 by detected product 7 surperficial places to be measured, be inserted on the guide and limit cover 4, move up and down and detect sleeve 2, itself and product surface to be measured is freely contacted, observe step 6 places, as the upper surface that detects sleeve 2 can think that then the facial contour degree of product measured surface is qualified, as shown in Figure 2 between the upper and lower surface of step 6; As the upper surface that detects sleeve 2 is lower than the lower surface of step 6 or is higher than the upper surface of step 6, can think that then the facial contour degree of product measured surface is defective, respectively as shown in Figure 3 and Figure 4.
