Abstract
The utility model discloses a kind of vernier calipers of Length discrepancy card base, including main scale, vernier scale and measuring mechanism, vernier scale is sleeved on main scale, main scale is fixedly arranged at the front end with fixed card base and lower fixed card base, one end of vernier scale is detachably equipped with movable card base and lower movable card base, the length of upper activity card base is less than the length of upper fixed card base, and the length of lower activity card base is less than the length of lower fixed card base.The utility model uses the card base of Length discrepancy, the gear shaft of not equal axle journals can directly be measured, when measurement, shorter card base resisted the higher point of the axle journal of gear under test axis, and longer card base resists the relatively low spot of the axle journal of gear under test axis, measure accuracy that is easy to operate, quick, and improving measurement.
Description
Technical field
The utility model belongs to measuring instrument technical field, and in particular to a kind of vernier caliper of Length discrepancy card base.
Background technology
Vernier caliper be a kind of measurement length, internal-and external diameter, depth measurer, vernier caliper is by main scale and being attached to energy on main scale
Vernier two parts of sliding are constituted, and vernier caliper is widely used in the fields such as machinery, chemical industry, building, the trip of the prior art
Slide calliper rule are marked, card base is all isometric, cannot directly measure the gear shaft for not waiting axle journals, therefore measures the gear shaft of not equal axle journals only
The energy indirect method of measurement, indirect method of measurement accuracy is not high, also often malfunctions because of counting loss.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies of existing technologies, and provides a kind of trip of Length discrepancy card base
Slide calliper rule are marked, the gear shaft for not waiting axle journals can be accurately measured.
To achieve the goals above, the utility model is realized using following technical scheme：
A kind of vernier caliper of Length discrepancy card base, including main scale, vernier scale and measuring mechanism, the vernier scale are sleeved on institute
It states on main scale, the main scale is fixedly arranged at the front end with fixed card base and lower fixed card base, and one end of the vernier scale is detachably pacified
Equipped with upper movable card base and lower movable card base, the length of the upper movable card base is less than the length of fixed card base, described
The length of lower activity card base is less than the length of the lower fixed card base.
Further, digital display component is installed, the reading of vernier scale can be directly on digital display component on the vernier scale
It is convenient intuitively to read directly with number display.
Further, the main scale and the vernier scale are prepared by duroplasts material, and duroplasts material is good insulation
Material can measure the workpiece with point.
Further, the upper movable card base and the lower movable card base are bolted on vernier scale, work as needs
The upper movable card base of different length and lower movable card base are replaced, loosers a bolt and removes movable card base and lower movable card base, installation
The upper movable card base and lower movable card base of upper different length, to measure the gear shaft of different axle journals.
Further, lock-screw is provided on the vernier scale, the lock-screw is for locking vernier scale.
The utility model has the beneficial effects that：
The vernier caliper of a kind of Length discrepancy card base provided by the utility model, due to the card base using Length discrepancy, Neng Gouzhi
Connect the gear shaft for measuring not equal axle journals, when measurement, shorter card base resisted the higher point of the axle journal of gear under test axis, longer card
Foot resists the relatively low spot of the axle journal of gear under test axis, and measurement is easy to operate, quick, and improves the accuracy of measurement.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Reference numeral therein is：1-main scale；2-workpiece；3-vernier scales；4-times movable card bases；5-upper active cards
Foot；6-above fix card base；7-times fixed card bases.
Specific implementation mode
To keep the purpose of this utility model, feature, advantage more apparent and understandable, with reference to the utility model
Attached drawing in embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that institute below
The embodiment of description is only the utility model a part of the embodiment, and not all embodiments.Based on the reality in the utility model
Example is applied, the every other embodiment that those skilled in the art is obtained shall fall within the protection scope of the present invention.
The present embodiment provides a kind of vernier calipers of Length discrepancy card base, as shown in Figure 1, including main scale 1, vernier scale 3 and
Measuring mechanism, above-mentioned vernier scale 3 are sleeved on the main scale 1, and above-mentioned main scale 1 is fixedly arranged at the front end with fixed card base 6 and lower fixation
One end of card base 7, above-mentioned vernier scale 3 is detachably equipped with movable card base 5 and lower movable card base 4, above-mentioned movable card base 5
Length is less than the length of above-mentioned fixed card base 6, and the length of above-mentioned lower movable card base 4 is less than the length of above-mentioned lower fixed card base 7,
It is not equal axle journals gear shaft, the lower movable card base 4 of the present embodiment and lower 7 Length discrepancy of fixed card base that work, which is workpiece 2, therefore can be with
Directly measure workpiece 2.
One as the present embodiment is preferably equipped with digital display component, the reading of vernier scale 3 can be direct on vernier scale 3
It is convenient intuitively to read with number display on digital display component.
One as the present embodiment is preferred, and main scale 1 and vernier scale 3 are prepared by duroplasts material, and duroplasts material is good
Good insulating materials can measure the workpiece 2 of electrification.
Preferably, upper activity card base 5 and lower movable card base 4 are bolted on vernier scale 3 to one as the present embodiment
On, when the upper movable card base 5 and lower movable card base 4 for needing replacing different length, looser a bolt the upper work removed on vernier scale 3
Dynamic card base 5 and lower movable card base 4 install the upper movable card base 5 of different length and lower movable card base 4, not coaxial to measure
The gear shaft of neck.
One as the present embodiment preferably, is provided with lock-screw on vernier scale 3, the lock-screw is swum for locking
Scale.
It is above-mentioned although specific embodiments of the present invention are described with reference to the accompanying drawings, but not to this practicality newly
The limitation of type protection domain, those skilled in the art should understand that, based on the technical solution of the present invention, ability
Field technique personnel need not make the creative labor the various modifications or changes that can be made still in the protection model of the utility model
In enclosing.
