Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
The utility model expanded range multi-function switch dimension measuring device, including main scale 1, vernier scale 2 and expansion joint
3, as shown in Figure 1.
There is chimb in the 1 upper and lower sides edge of main scale along the design of main scale left and right directions；The design of about 2 two sides of vernier scale has card
Slot is cooperated by card slot and chimb, is placed on vernier scale 2 on main scale 1, guarantees that main scale 1 is closely connect with vernier scale 2, and vernier
Ruler 2 can be moved left and right along main scale 1.2 upper side of vernier scale is provided with threaded hole；Threaded hole internal screw thread connects fastening screw, by twisting
Tight fastening screw makes fastening screw hold out against 1 upper side of main scale, realizes positioning of the vernier scale 2 on main scale 1.It is marked on vernier scale 2
There are scale, scale 0 left end in vernier scale 2.
Expansion joint 3 is installed on left end (starting point) end face of above-mentioned main scale 1, is set on the 3 left end end face of expansion joint
Main scale range is extended for being inserted into other slide calliper rule in respect of inserting groove；It is also provided with threaded hole on above-mentioned 3 downside of expansion joint, with
Inserting groove connection；Threaded hole internal screw thread connects fastening screw, by tightening fastening screw, can will be inserted into the slide calliper rule 1 in link slot
Fixation is held out against with.
Due to opening inserting groove in 1 left end expansion joint 3 of main scale, then expansion joint 3 and 1 abutted surface of main scale have certain thick
A is spent, therefore after being inserted into other slide calliper rule, in order to guarantee the continuity between be inserted into slide calliper rule and main scale 1 are read, in main scale 1
For main scale scale on front along 1 left and right directions of main scale mark by 1 left end of main scale, starting point reading is expansion joint 3 and master
Ruler 1 connects face thickness a.The stability and cost of measuring device are considered in the utility model, design a is 3mm, i.e. main scale scale rises
Initial value is 3mm.As a result, by being inserted into slide calliper rule in inserting groove, the range of main scale 1 is increased indirectly, thus makes the utility model
Measuring device can replace box ruler to use when measuring the larger sizes such as spacing, and measurement accuracy is higher.
Long measuring jaw 201 is also devised on above-mentioned 2 bottom surface of vernier scale, long 201 left side of measuring jaw is numerical value plane, with vernier scale
2 left sides are coplanar；Cooperate the utility model measuring device and offset scale, extend offset scale range, realizes large scale rail branch
Away from measurement, concrete mode are as follows: the grafting offset distance measuring scale first in the inserting groove of 3 left end end face of expansion joint, by offset scale
End measuring jaw is bonded with side rail head of rail lateral surface, and offset scale is bonded two rail tops of track switch with 1 bottom surface of main scale respectively
Face makes offset scale and main scale 1 perpendicular to rail surface；Subsequent moving cursor ruler 2, makes long 201 left side of measuring jaw and other side steel
The outside face paste of rail and；The sum of the reading of main scale 1 and offset scale length are rail offset distance distance at this time.
Above-mentioned 201 lower end of long measuring jaw is also devised with secondary pawl 202, and secondary 202 left side of pawl is vertical plane, left with long measuring jaw 201
Side is coplanar, cooperates the utility model measuring device and offset scale, extends offset scale two, realizes large scale railroad turnout steel rail frame
Frame dimensional measurement, concrete mode are as follows: the grafting offset distance measuring scale first in the inserting groove of 3 left end end face of expansion joint, by offset distance
Secondary pawl side on the end measuring jaw of ruler is bonded with side rail head of rail medial surface, and subsequent moving cursor ruler 2 makes long measuring jaw 201
On 202 side of secondary pawl and other side rail inside face paste and；The sum of the reading of main scale 1 and offset scale length at this time, in addition branch
The thickness of the secondary pawl 202 on secondary pawl and long measuring jaw 201 on the end measuring jaw of carpenters square, as rail offset distance distance.In order to read
Convenient, the thickness design of secondary pawl 202 on the long measuring jaw 201 is identical with the secondary pawl thickness on the end measuring jaw of offset scale
5mm。
Above-mentioned 3 upper side of expansion joint design has the first measuring jaw 301, and 301 right side of the first measuring jaw is perpendicular, with master
1 left end end face of ruler is coplanar；Be also devised with the second measuring jaw 203 on the upper side of vernier scale 2 simultaneously, 203 top surface of the second measuring jaw with
First measuring jaw 301 flushes, and left side is coplanar with 1 left end end face of main scale.As a result, when carrying out rail head of rail width measurement, first
1 downside of main scale is bonded with rail head of rail top surface, makes main scale 1 perpendicular to rail surface；Then, by 301 right side of the first measuring jaw
Face is bonded with rail head of rail side wall；Finally, moving cursor ruler 2, pastes 301 left side of the first measuring jaw and rail head of rail opposing sidewalls
It closes；It is the rail head of rail width under gauge line at 16mm that the reading of main scale 1, which subtracts a, at this time.
In order to guarantee when carrying out rail head of rail width measurement, the levelness of main scale 1, therefore in the trailing flank of vernier scale 2
Top is equipped with level measurement device 5, as shown in Fig. 2, horizontal display apparatus is that the band being made of packaging body and spirit bubble is installed
The level meter in hole, center line and 1 keeping parallelism of main scale, when being measured using the present apparatus, as long as guarantee level measurement device 5 in
Bubble keep horizontal, measurement error caused by being avoided at once because of 1 injustice of main scale.
