Abstract
A kind of external pelivimetry pawl vernier caliper that improves, comprises main scale, secondary chi, and described main scale comprises a cross bar and the fixation measuring pawl of being located at cross bar one end, and the cross bar surface of main scale is provided with scale; Described secondary chi is square member, is provided with scale on the cross bar surface of secondary chi, and the lower plumbing bar of secondary chi is movable measuring claw; Described secondary chi is set on the cross bar of main scale, can move left and right; Feature is: a lateral surface is set and medial surface is measuring claw parallel to each other at described fixation measuring pawl, fixation measuring pawl medial surface and main scale zero graduation line are in same plane, a medial surface is set and lateral surface is measuring claw parallel to each other at the movable measuring claw of secondary chi, described fixation measuring pawl and movable measuring claw are parallel to each other, described fixation measuring pawl and movable measuring claw surface are provided with scale, and fixation measuring pawl scale and movable measuring claw scale are in same level.The utility model, has increased the purposes of vernier caliper, and it is simple in structure, practical and convenient.
Description
Technical field
The utility model belongs to survey instrument, relates to a kind of vernier caliper, is specially a kind of external pelivimetry pawl vernier caliper that improves.
Background technology
Vernier caliper is a kind of conventional survey instrument, and vernier caliper has two secondary movable measuring jaws, is respectively external pelivimetry pawl and interior measuring claw, and wherein external pelivimetry pawl is commonly used to measure length or external diameter, and interior measuring claw is used for measuring internal diameter.Owing to being subject to the restriction of external pelivimetry claw shape, especially the measurement of male member symmetry, recess width and the part workpiece degree of depth is generally used to common calliper, internal diameter chi and pit gauge conjunction measuring, the occasion that this measuring method is not high to accuracy requirement, substantially can meet the demands, shortcoming will ceaselessly be changed survey instrument exactly, can not survey instrument be met to above-mentioned measurement requirement with same.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and the improvement external pelivimetry pawl vernier caliper of a kind of measuring workpieces symmetry, recess width and the part workpiece degree of depth is provided.
The purpose of this utility model realizes by the following technical solutions: a kind of external pelivimetry pawl vernier caliper that improves, comprise main scale, secondary chi, and described main scale comprises a cross bar and the fixation measuring pawl of being located at cross bar one end, the cross bar surface of main scale is provided with scale; Described secondary chi is square member, is provided with scale on the cross bar surface of secondary chi, and the lower plumbing bar of secondary chi is movable measuring claw; Described secondary chi is set on the cross bar of main scale, can move left and right; Feature is: a lateral surface is set and medial surface is measuring claw parallel to each other at described fixation measuring pawl, fixation measuring pawl medial surface and main scale zero graduation line are in same plane, a medial surface is set and lateral surface is measuring claw parallel to each other at the movable measuring claw of secondary chi, described fixation measuring pawl and movable measuring claw are parallel to each other, described fixation measuring pawl and movable measuring claw surface are provided with scale, and fixation measuring pawl scale and movable measuring claw scale are in same level.
The utility model function is simple, measuring method and conventional measuring tool use similar, not only convenient but also accurate when measuring workpieces symmetry, recess width and the part workpiece degree of depth, and crudy and the efficiency of whole engineering goods are improved, and overcome the measurement difficulty of traditional vernier caliper, the purposes that has increased vernier caliper, it is simple in structure, practical and convenient.
Brief description of the drawings
Accompanying drawing 1 is the utility model structural representation.
Below in conjunction with accompanying drawing, the utility model is further described.
embodiment
Referring to Fig. 1, a kind of external pelivimetry pawl vernier caliper that improves, comprises main scale 1, secondary chi 2, and described main scale 1 comprises a cross bar and the fixation measuring pawl 3 of being located at cross bar one end, and the cross bar surface of main scale 1 is provided with scale; Described secondary chi 2 is square member, is provided with scale on the cross bar surface of secondary chi, and the lower plumbing bar of secondary chi is movable measuring claw 4; Described secondary chi 2 is set on the cross bar of main scale 1, can move left and right; Feature is: at described fixation measuring pawl 3, a lateral surface 5 being set is measuring claws parallel to each other with medial surface 6, fixation measuring pawl 3 medial surfaces 6 and main scale 1 zero graduation line are in same plane, at the movable measuring claw 4 of secondary chi 2, a medial surface 7 being set is measuring claws parallel to each other with lateral surface 8, described fixation measuring pawl 3 and movable measuring claw 4 are parallel to each other, described fixation measuring pawl 3 and movable measuring claw 4 surfaces are provided with scale, and fixation measuring pawl 3 scales and movable measuring claw 4 scales are in same level.
