Abstract
The utility model provides a vernier caliper, comprising a main scale marked a scale and a vernier, and the vernier is equipped with a measuring jaw. The vernier caliper is characterized in that the main scale is equipped with a second measuring jaw corresponding to the measuring jaw of the vernier and also a chute perpendicular to the main scale, a dovetail structure is arranged in the chute, the second measuring jaw is equipped with a dovetail guide groove, and via the cooperation of the dovetail guide groove and the dovetail structure, the second measuring jaw can move up and down in the chute of the main scale. Compared with the prior art, by using the vernier caliper of the utility model, the position of the second measuring jaw can be adjusted up and down according to the cross section situation of a to-be-tested workpiece, so that the limitation of the prior art is overcome, the vernier caliper can be used to measure to-be-tested workpieces of larger cross sections accurately, the measurement error is reduced, and the operation is simple.
Description
[technical field]
The utility model relates to a kind of vernier caliper, particularly a kind of vernier caliper that is applied to measure the bigger workpiece for measurement of section.
[background technology]
Vernier caliper is a kind of measurer that is mainly used to measure length, interior external diameter.Vernier caliper is by main scale and be attached to the vernier two parts that can horizontally slip on the main scale and constitute, correspondence is provided with two secondary movable measuring jaws on its main scale and the vernier, be respectively interior measuring claw and external pelivimetry pawl, the length of the movable measuring jaw of every width of cloth is identical, interior measuring claw is commonly used to measure internal diameter, and the external pelivimetry pawl is commonly used to measure length and external diameter.
The vernier caliper of prior art, the length of every width of cloth measuring jaw is identical, and the measuring jaw on the main scale is fixed or one-body molded with main scale, when being used for the length of measuring workpieces or interior external diameter, when the section of workpiece for measurement during greater than the measuring jaw length of this vernier caliper, because two measuring jaws of this vernier caliper can't block two to be measured edge of workpiece for measurement simultaneously, thereby can't finish accurate measurement.
[utility model content]
In view of the above problems, the purpose of this utility model is to provide a kind of vernier caliper that is applied to measure the bigger workpiece for measurement of section.
In order to achieve the above object, the utility model provides a kind of vernier caliper, it comprises that one indicates the main scale and a vernier of scale, this vernier is provided with one first measuring jaw, on this main scale to being provided with one second measuring jaw by first measuring jaw, it is characterized in that, also be provided with a chute perpendicular to main scale on this main scale, be provided with a dovetail structure in this chute, this second measuring jaw is provided with a dovetail guide groove, by cooperating of this dovetail guide groove and this dovetail structure, this second measuring jaw can be done in the chute of this main scale and move up and down.
Preferably, this vernier caliper also comprises a measuring jaw dog screw, and it is movably set on the side of this main scale front end, when locking this measuring jaw dog screw, it is inconsistent that its front end enters the side of this chute and this second measuring jaw, and provide coupling mechanism force that this second measuring jaw is fixing at an arbitrary position.
Compared with prior art, the utility model vernier caliper can be adjusted the position of this second measuring jaw according to the situation of workpiece for measurement section up and down, has overcome the limitation of prior art, makes vernier caliper can be used in the bigger workpiece for measurement of accurate measurement section, reduced measuring error, simple to operate.

[embodiment]
The below describes in further detail embodiment of the present utility model in conjunction with the accompanying drawings.
Please refer to Fig. 1 to Fig. 3, the utility model provides a kind of vernier caliper, and it comprises that one indicates the main scale 10 and a vernier 20 of scale.This vernier 20 is provided with the first external pelivimetry pawl, 21, first an interior measuring claw 22 and the vernier dog screw 23.This main scale 10 is provided with second measuring jaw 30, and the main body of this second measuring jaw 30 is a rectangle, and its two ends are respectively arranged with measuring claw 32 in the second external pelivimetry pawl 31 and second.Also be provided with a chute 11 perpendicular to this main scale 10 on this main scale 10, this chute 11 is provided with a dovetail structure 12, and this second measuring jaw 30 is provided with a dovetail guide groove 33.By cooperating of this dovetail guide groove 33 and this dovetail structure 12, the main part of this second measuring jaw 30 can be done in this chute 11 and move up and down.
This vernier caliper also comprises a measuring jaw dog screw 13, its activity is arranged on the front end side of this main scale 10, when locking this measuring jaw dog screw 13, it is inconsistent with the side of this second measuring jaw 30 that its front end enters this chute 11, and provide coupling mechanism force that this second measuring jaw 30 is fixing at an arbitrary position.
See also Fig. 4, it illustrates the work synoptic diagram of the utility model vernier caliper.Workpiece for measurement 100 has first plane 110 and second plane 120 that is parallel to each other, and there is an oblique section 130 on this first plane 110 and 120 on this second plane.Measure between this first plane 110 and this second plane 120 apart from the time, this second measuring jaw 30 that moves up earlier makes these second external pelivimetry pawl, 32 parallel cards be buckled in the edge on second plane 120 of this workpiece for measurement, and lock this measuring jaw dog screw 13, this second measuring jaw 30 is maintained static; Move this vernier 20 then, make these first external pelivimetry pawl, 21 parallel cards be buckled in the edge on this first plane 110, and lock this vernier dog screw 23; Can obtain first plane 110 of this workpiece 100 and the distance values between second plane 120 at reading on the vernier caliper.
Compared with prior art, the utility model vernier caliper can be adjusted the position of this second measuring jaw according to the situation of workpiece for measurement section up and down, finish measurement smoothly, overcome the limitation of prior art, make vernier caliper can be used in the bigger workpiece for measurement of accurate measurement section, reduced measuring error, simple to operate.
Be pointed out that; the utility model is not limited to above-mentioned embodiment; any simple modification, equivalent variations and modification that any those skilled in the art do the foregoing description based on technical solutions of the utility model all fall in the protection domain of the present utility model.
