Description
Technical field
It the utility model is related to dimensional measuring instrument, and in particular to the calliper structure of measurement inner hole groove.
Background technology
Calliper is the instrument for measuring length.During with the diameter of calliper measured hole, the line of two card base measuring surface is set to hang down
Direct join intersects at interior axially bored line, and one card base is leaned against on hole wall during measurement, and some are gradual by the slightly biased the inside in aperture for another card base
Outwards test, and swung along the circumferencial direction of hole wall, when the distance minimum of swing, the opening size of caliper gauge is exactly that endoporus is straight
Footpath.
, it is necessary to first measure endoporus size when calliper measures, the opening size between two card bases of gage measuring is then used again.
But, can not measurement card, it is necessary to close card base and then calliper could be taken out after being measured with inside plain calipers when being measured for hole internal channel
The actual size that angle is opened.
The content of the invention
The utility model provides calliper, and the utility model is solved and accurately measured hole internal channel can not asked with calliper
Topic.
To solve the above problems, the utility model adopts the following technical scheme that：Calliper, including the first caliper, main jointed shaft,
Pressure sensor and cylinder；First caliper and the second caliper are arranged in a crossed manner, and crossover location is provided with main jointed shaft；First caliper
The measurement claw of outside lateral bending is respectively arranged with the second caliper lower end；Cylinder is hinged with the second caliper upper end, the piston of cylinder
Boom end is hinged with the first caliper upper end；Pressure sensor is installed on the cylinder body of cylinder；Pressure sensor connects controller,
Controller connects computer.
The advantages of the utility model, has：The size of endoporus further groove can be measured with claw, groove can be gone out with direct measurement
Width, improve measurement accuracy.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
Fig. 2 is the utility model line map.
Symbol description in figure：First caliper 1, main jointed shaft 2, the second caliper 3, pressure sensor 4, cylinder 5, piston rod 6,
Measured workpiece 7, controller 8, computer 9.
Embodiment
The utility model is described in detail with optimal embodiment below.
As shown in Figure 1-2, calliper, including the first caliper 1, main jointed shaft 2, pressure sensor 4 and cylinder 5；First caliper 1
It is arranged in a crossed manner with the second caliper 3, crossover location is provided with main jointed shaft 2；First caliper 1 and the lower end of the second caliper 3 are set respectively
It is equipped with the measurement claw of outside lateral bending；Cylinder 5 is hinged with the upper end of the second caliper 3, the end of piston rod 6 of cylinder 5 and the first caliper 1
Upper end is hinged；Pressure sensor 4 is installed on the cylinder body of cylinder 5.
During measurement, the first caliper 1 and the lower end of the second caliper 3 are inserted in the endoporus of measured workpiece 7, claw, which opens, to be surveyed
The width of metering-orifice inner groovy.Pressure sensor 4 is connected with controller 8, and controller 8 connects computer, and computer is according to receiving
The size of air pressure is calculated as the opening dimension of claw, and then calculates the measured value of claw.
Finally it should be noted that：Obviously, above-described embodiment is only intended to clearly illustrate the utility model example,
And the restriction not to embodiment.For those of ordinary skill in the field, may be used also on the basis of the above description
To make other changes in different forms.There is no necessity and possibility to exhaust all the enbodiments.And thus
Among the obvious changes or variations amplified out is still in the scope of protection of the utility model.
