Abstract
The utility model provides a split-type reference snap-gauge. The original reference snap-gauge adopts a horseshoe-shaped structure, and has the problem that the grinding time is difficult to control in the machining process; if the grinding time is too long, the whole reference snap-gauge is out of tolerance because of the too long grinding time; if the grinding time is too short, the whole reference snap-gauge cannot meet technical requirements; and during the machining process, the achieved highest precision is 2 mum. The split-type reference snap-gauge comprises a main body (1); a positioning gauge block (2), a cushion block (3), a gauge block (4) and a gasket (5) are sequentially mounted on the main body; a bolt (6) penetrates the main body, the positioning gauge block, the cushion block, the gauge block and the gasket; and the bolt is connected with a nut (7) to be locked tightly. The utility model is used for the reference snap-gauge.
Description
Technical field:
the utility model relates to a kind of general measurer field, is specifically related to a kind of split type standard caliper.
Background technology:
original standard caliper adopts the horseshoe type structure; There is the problem of the bad control of milling time length in this structure clamp in process; If milling time is long, the standard caliper global existence causes the standard caliper dimension overproof because of milling time is long, if milling time is too short; Do not reach technical requirement; In process, reaching full accuracy is 2um, and we will examine and determine inside dial indicator and the survey ball of three-coordinates measuring machine below the 10mm with it now; Its accuracy requirement is below 1um, so the clamp of horseshoe type does not just reach technical requirement.And present stage does not have other survey instruments to use.
Summary of the invention:
purpose of the utility model provides a kind of split type standard caliper of manpower pressuring method dredging pipeline.
Above-mentioned purpose realizes through following technical scheme:
a kind of split type standard caliper; Its composition comprises: main body; Described main body is equipped with location gauge block, cushion block, gauge block and pad in order; Bolt passes described main body and described location gauge block and described cushion block and described gauge block and described pad, described bolt attaching nut and locking.
described split type standard caliper, described one group of gauge block is placed on described cushion block one side.
Beneficial effect:
1. the split type standard caliper precision of the utility model can reach 0.3um, can satisfy the actual measurement requirement fully.
the utility model adopts bolt, nut lock structure; Gauge block and cushion block are locked under a suitable coupling mechanism force effect; Should guarantee the reliable lock of standard caliper, prevent again to produce of the influence of excessive structural stress, when coupling mechanism force is too small the standard caliper precision because of coupling mechanism force is excessive; Gauge block and cushion block produce unnecessary becoming flexible, thereby have improved the stability of standard caliper.
the utility model adopts bolt, nut lock structure, helps to reduce the stress deformation that causes because of coupling mechanism force is excessive and the gauge block of avoiding causing because of coupling mechanism force is too small becomes flexible.
The coupling mechanism force of
the utility model is even, solid and reliable, has improved measuring accuracy.
the utility model is compared with the clamp of existing horseshoe type structure, can the power of location gauge block, cushion block, gauge block and pad locking be adjusted according to actual operating position; The gauge block that helps to reduce the stress deformation that causes because of coupling mechanism force is excessive and avoid causing because of coupling mechanism force is too small is loosening.
Description of drawings:
accompanying drawing 1 is the structural representation of this product.
Embodiment:
Embodiment 1:
a kind of split type standard caliper; Its composition comprises: main body 1; Described main body is equipped with location gauge block 2, cushion block 3, gauge block 4 and pad 5 in order; Bolt 6 passes described main body, described location gauge block, described cushion block, described gauge block and described pad, described bolt attaching nut 7 and locking.
Embodiment 2:
Embodiment 3:
described split type standard caliper, described cushion block one are sidelong and are put one group on gauge block, the hole that all has the fastening screw screw bolt and nut to use on described placement gauge block and the main body.
Embodiment 4:
Claims (2)
