Description
Technical field
The utility model belongs to the survey instrument field, specifically, relates to a kind of measurement verifying attachment that uses during with the workpiece of dovetail groove in processing, more particularly, relates to a kind of dovetail groove verifying attachment.
Background technology
Dovetail groove is a kind of physical construction commonly used, and mechanical relative motion is normally done in its effect, has kinematic accuracy high, and motion stabilization rocks the advantages such as little, and dovetail groove is general to be used in conjunction with trapezoidal rails, has been to lead and supporting role.In modern industry, the application of dovetail groove is very general, for example often uses on the planker of lathe.But the measurement after the dovetail groove processing is a problem always, repeatedly measure different positions by survey instruments such as vernier calipers, and the measurement formality is loaded down with trivial details, waste time and energy, and measurement result easily has error.And present improvement all is the improvement on survey instrument, and the improvement of these survey instruments becomes convenient for surveying work, but or will to different position measurements many times, not have to solve the problem that at every turn need to repeatedly measure.
China Patent No. 200820064879.6, open day on 06 10th, 2009, the patent document that a name is called vernier caliper is disclosed, relate to a kind of measurement inside-outside vernier callipers, it comprises compressing tablet, chi frame, pivot pin, the measuring head of chi frame, a blade with main scale, clench nail, the secondary chi of band, its technical essential be at the two ends of blade and chi frame respectively symmetry be connected to a chi frame, be connected with a pivot pin two chi frame intersection area work, make two chi framves connect into " V " shape or " X " shape clamp, be provided with a measuring head at the chi frame other end.It utilizes leg-of-mutton ratio of similitude principle design to form.That this utility model has is simple and compact for structure, measurement range is wide, and measuring accuracy is high, easy to carry, the characteristics such as long service life.
China Patent No. 200820042321.8, open day on 07 08th, 2009, the patent document that a kind of name is called Novel vernier caliper is disclosed, this utility model discloses a kind of Novel vernier caliper, it comprises main scale, vernier and measurement pin, and main scale is provided with scale, measures pin and is divided into fixation measuring pin and the movable pin of measuring, the vertical fastening back side that is installed in main scale one end of described fixation measuring pin, the movable vertical fastening back side that is installed in vernier of pin of measuring.The said structure that this utility model adopts is owing to having changed the relative position of measuring between pin and the main scale, so that reading out data is more convenient when measuring; In addition, the gaging pressure that produces during measurement can not have influence on the gap between main scale and the vernier yet, thereby can improve measuring accuracy.
Above-mentioned two kinds of patents are the improvement to vernier caliper, convenience and the accuracy of surveying work have been increased, but owing to the singularity of oat tail groove structure, still need to measure the size of a plurality of positions during measurement, could determine whether the size of dovetail groove is qualified, whether can normally use, use these vernier caliper check dovetail groove workpiece whether qualified, operation or cumbersome, checkability is low, also easily be subjected to human factor to cause error, also fundamentally do not solve the problem of measuring often.
Summary of the invention
The problem that solves
Whether qualified for check dovetail groove in the prior art, needs are measured the size of a plurality of positions, and operation is cumbersome, checkability is low, easily be subjected to human factor to cause the problem of error, the utility model provides a kind of dovetail groove verifying attachment, and whether the size that can detect fast dovetail groove is qualified.
Technical scheme
In order to address the above problem, the technical scheme that the utility model adopts is:
A kind of dovetail groove verifying attachment, comprise handle and detect body, the outside surface that described detection body is gone up is along its length connected to form successively by the first side, bottom surface, the second side and upper surface, detecting body is being isosceles trapezoid perpendicular to the xsect on self length direction, the width of upper surface is less than the width of bottom surface, and the width of the first side equals the width of the second side; Described handle is connected with the detection body at the upper surface place.
Further, on the described handle rubber sleeve is arranged.
Further, the angle of described the first side and bottom surface is 60 °.Namely the angle of the second side and bottom surface also is 60 °.The setting of this angle is because the side of most dovetail groove inside and the angle of bottom surface are 60 °.
Further, at the upper surface place screw is arranged on the described detection body, an end of handle has the screw thread corresponding with screw on the detection body, is threaded connection between handle and the detection body.
Further, described handle and detecting between the body by being welded to connect.
When using this device to carry out the dovetail groove check, can directly this device be placed in the dovetail groove that to check, if put to enter, illustrate that dovetail groove is too small, inaccuracy of dimensions; If just in time pass through, illustrate that dovetail groove is qualified; If by than being easier to, the a bit large of dovetail groove processing is described, use feeler gauge this moment, can measure exactly the distance between this device and the dovetail groove, can judge easily size whether in rational error range according to the size of measuring, in error range, explanation can be used, not in error range, inaccuracy of dimensions is described.
Beneficial effect
Than prior art, the beneficial effects of the utility model are:
(1) the utility model comprises handle and detects body, detect body by the first side, the bottom surface, the second side and upper surface connect to form successively, detecting body is being isosceles trapezoid perpendicular to the xsect on self length direction, handle is connected with the detection body, when using this device to carry out the dovetail groove check, can directly this device be placed in the dovetail groove that to check, measure the dovetail groove size convenient when whether qualified, efficiently, for the qualified product less than normal with size, only need to measure once to get final product, for size product bigger than normal, can use feeler gauge to judge that fast size is whether in error range;
