Abstract
The utility model relates to a kind of taper hole diameter measurement vernier calipers of measurable taper hole diameter, including blade, the ruler frame being mounted on by claw pressing plate and fastening screw on blade, the lock-screw being mounted between blade and ruler frame, adjust the micro-adjusting mechanism of position precision of the ruler frame on blade, the ruler frame claw that the blade claw and ruler frame head that blade head has have is symmetrical intilted inclined-plane in vertical direction, it is horizontal plane in same level direction, blade claw and ruler frame claw are two contacts for being inserted into and matching in taper hole with taper hole, the distance between the two inclined-plane is the measurement diameter of taper hole, the utility model structure is simple, practical function, the practical problem that solution taper hole and cone angle hole are unable to measure, measured value is more accurate.
Description
Technical field
The utility model belongs to measurer applied technical field more particularly to a kind of taper hole diameter of measurable taper hole diameter is surveyed
Amount uses vernier caliper.
Background technique
Conventional calliper to measure contact is straight platform contact, can measure the data such as outer diameter, internal diameter, length, and require quilt
Surveying workpiece has the line being in contact with straight platform contact or face.Due to taper hole can not with straight platform contacts mates, using conventional vernier caliper
When will appear the inaccurate situation of measurement, current common measurement means be measure after inscription rubbing, but such measurement method there are still compared with
Big error.
Utility model content
A kind of measurement taper hole diameter is provided the purpose of the utility model is to overcome the deficiencies in the prior art can
Error is controlled in the taper hole diameter measurement vernier caliper of 0.02mm, which improves examination and test of products precision, reinforces
The quality assurance of product.
Purpose of the utility model is realized as follows: a kind of taper hole diameter measurement vernier caliper, including blade, pass through
Ruler frame that claw pressing plate and fastening screw are mounted on blade, adjusts ruler frame at the lock-screw being mounted between blade and ruler frame
The micro-adjusting mechanism of position precision on blade, it is characterised in that: the blade claw and ruler frame head that blade head has have
Ruler frame claw in vertical direction be symmetrical intilted inclined-plane, be horizontal plane in same level direction, blade claw and
Ruler frame claw is two contacts for being inserted into and matching in taper hole with taper hole, and the distance between the two inclined-plane is that the measurement of taper hole is straight
Diameter.
Two contacts that the taper hole diameter measurement vernier caliper is equipped with are two matched with measured taper hole
Conical contact tip, two conical contact tip difference installation activities are on the head of blade claw and ruler frame claw, with blade claw and ruler
It is to be detachably connected relationship between the head of frame claw.
Two conical contact tips are tailor-made according to measured taper hole taper or angle or replace.
The utility model measures taper hole controlled diameter error in 0.02mm, therefore the taper hole vernier caliper has the examination and test of products
Precision is high, can guarantee the advantages of product quality.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the taper hole diameter measurement vernier caliper of the utility model.
Fig. 2 is the schematic diagram when taper hole diameter measurement vernier caliper of the utility model specifically measures.
In figure, 1 conical contact tip, 2 blades, 3 claw pressing plates, 4 lock-screws, 5 fastening screws, 6 ruler frames, 7 ruler frames, 8 fine tunings
Mechanism, 9, taper work.
Specific embodiment
As shown in Figure 1, 2, a kind of taper hole diameter measurement vernier caliper, including blade 2, by claw pressing plate 3 and fastening
Ruler frame 7 that screw 4 is mounted on blade 2, the lock-screw 4 being mounted between blade 2 and ruler frame 7 adjust ruler frame 7 in blade 2
On position precision micro-adjusting mechanism 8, the ruler frame claw that the blade claw and ruler frame head that blade head has have is vertical
Direction is symmetrical intilted taper work, is horizontal plane in same level direction, blade claw and ruler frame claw are
Two contacts matched in insertion taper hole with taper hole, the distance between the two inclined-plane are the measurement diameter of taper hole.
Two contacts that the taper hole diameter measurement vernier caliper is equipped with are the taper hole phase with measured taper work 9
Two conical contact tips of cooperation, two conical contact tip difference installation activities are on the head of blade claw and ruler frame claw, with ruler
It is to be detachably connected relationship between body claw and the head of ruler frame card 8.
Two conical contact tips are tailor-made according to measured taper hole taper or angle or replace.
The utility model relates to a kind of vernier calipers of measurable taper hole diameter.The technical solution of the utility model is ruler
The conical contact tip that body claw has taper hole workpiece to match with ruler frame claw.The claw contact of blade and ruler frame is equipped with and bores
The taper or angle that hole matches；Slide calliper rule contact position is put into tested work by taper hole diameter measurement vernier caliper shown in figure
Part cone mouth oral area fits contact lower end platform and taper hole aperture end face, circumferentially shakes the maximum measurement of ruler frame claw observation
Value.Slide calliper rule provided by the utility model stop hole measurement in taper hole, pipe screw thread and have obtained good application.
