Description
Technical field
The utility model is related to a kind of devices for measuring lath two sides width.Specifically, it is wide by measuring band steel two sides
It spends and then calculates the whether qualified band steel two sides width difference detection device of band steel gradient.
Background technology
It, need to be to two sides width difference, that is, gradient of band steel to examine the band steel processed whether qualified in band steel processing industry
It measures.Current measuring method is using traditional vernier caliper measurement.It is well known that traditional vernier caliper contains directly
Ruler has scale on ruler, and zero graduation one end of ruler, which has, determines snap arm, and card can be moved along the dynamic snap arm of its longitudinal sliding motion by having on ruler
Arm and determine snap arm adjacent side it is parallel and longitudinal direction with ruler is perpendicular.During measurement, dynamic snap arm can only be moved, first makes snap arm
Outer end is respectively placed in the both sides of band steel one side with the outer end tip for determining snap arm, measures the width of band steel one side.Make snap arm again
Outer end is respectively placed in the both sides of band steel another side with the outer end tip for determining snap arm, measures the width of band steel another side.Then, with one
The width value in face subtracts the width value of another side, calculates to obtain two sides width error, you can obtain the gradient of band steel.Added with this to examine
Whether the band steel that work goes out is qualified.Since the dynamic snap arm of traditional vernier caliper is parallel with the adjacent side for determining snap arm, during measurement, snap arm is moved
Outer end and determine the outer end tip of snap arm to be respectively placed in the both sides of band steel one side and the both sides of another side be by means of operator
Manual operations realizes, same operator is to same section flat to the measurement result of same section of band steel different time and different operation person
The measurement result of steel is all difficult to be consistent, and measurement error is larger, can not measure the accurate gradient of band steel, it is difficult to determine to process
Band steel it is whether qualified.
Utility model content
Problem to be solved in the utility model is to provide a kind of band steel two sides width difference detection device.This detection device,
Measurement error is small, can measure the accurate gradient of band steel, determines whether the band steel processed is qualified.
The above problem to be solved in the utility model is realized by following technical scheme：
The band steel two sides width difference detection device of the utility model includes vernier caliper.The vernier caliper contains ruler,
Have scale on ruler, zero graduation one end of ruler, which has, determines snap arm, have on ruler can along the dynamic snap arm of its longitudinal sliding motion, move snap arm and
The adjacent side for determining snap arm is parallel and longitudinal direction with ruler is perpendicular.Its main feature is that determine have wedge shape on the adjacent side of snap arm and dynamic snap arm
Slot, the wedge groove is right angled triangle, and the bevel edge of two right angled triangles is overlapped with the slot bottom of wedge groove so that two
An isosceles triangle space is formed after a wedge groove docking.
As can be seen from the above scheme, due to having wedge groove, the wedge shape on the adjacent side for determining snap arm and dynamic snap arm
Slot is right angled triangle, and the bevel edge of two right angled triangles is overlapped with the slot bottom of wedge groove so that two wedge grooves pair
An isosceles triangle space is formed after connecing.During measurement, make the base in isosceles triangle space downward, and by tested band steel section
Two longitudinal edges are clamped on the base in isosceles triangle space, and the width value of band steel one side is first read from ruler.Then, will
Band steel, which is turned out, transversely rotates 180 degree, and adjusts dynamic snap arm, make two longitudinal edges of band steel in isosceles triangle space
Two bases be in contact, and from ruler read band steel another side width value.Finally, it is subtracted with the width value of band steel one side
The width value of its another side, the width for obtaining band steel two sides are poor, you can know whether the gradient of tested band steel is qualified.With background skill
Make snap arm outer end using manual operations in art and determine snap arm outer end tip and be respectively placed in both sides and the another side of band steel one side
Both sides are compared to measure band steel section two sides width difference, using high the utility model, when same operator is to same section of band steel difference
Between measurement result and different operation person the measurement result of same section of band steel can be consistent completely, so as to eliminate measure
Error can measure the accurate gradient of band steel, can determine whether the band steel processed is qualified.
Description of the drawings
Fig. 1 is the band steel two sides width difference structure of the detecting device schematic diagram of the utility model；
State when Fig. 2 is the band steel two sides width difference detection device test one face width of band steel using the utility model is shown
It is intended to；
State when Fig. 3 is the band steel two sides width difference detection device test band steel another side width using the utility model
Schematic diagram.
Specific embodiment
As shown in Figure 1, the band steel two sides width difference detection device of the utility model includes vernier caliper.The vernier caliper
Containing ruler, the longitudinal direction of ruler is machined with scale on one side, and zero graduation one end of ruler, which is fixed with, determines snap arm, and being provided on ruler can
Along the dynamic snap arm of its longitudinal sliding motion, dynamic snap arm and determine snap arm adjacent side it is parallel and longitudinal direction with ruler is perpendicular.Determine snap arm and
Wedge groove is machined on the adjacent side of dynamic snap arm, the wedge groove is right angled triangle, is made of the bevel edge of right angled triangle
The slot bottom of wedge groove so that form an isosceles triangle space after two wedge groove docking.
As shown in Figures 2 and 3, during measurement, the base for making isosceles triangle space downward indulges two of tested band steel section
It is clamped in the base in isosceles triangle space to side, the width value a of band steel one side is first read from ruler, sees Fig. 2.Then,
Band steel is turned out and transversely rotates 180 degree, and adjusts dynamic snap arm, make two longitudinal edges of band steel with isosceles triangle space
Corresponding two slot bottoms in base are in contact, and the width value b of band steel another side is read from ruler, see Fig. 3.Finally, formula is used
A-b=c obtains the width difference c on band steel two sides, you can knows whether the gradient of tested band steel is qualified.
