Description
Technical field:
The utility model belongs to mechanical equipment technical field, and in particular to a kind of large diameter hole calipers.
Background technique:
With the fast development of China's machine-building, the requirements such as the detection efficiency of online production product, method, precision are got over
Come higher.The inner hole of machinework major diameter, the accuracy of manufacture is higher and higher, and it is fast that conventional detection means is not able to satisfy production scene
Speed, the demand accurately measured.Existing measuring device has the shortcomings that big or not easy to operate from great, dynamometry.In order to improve scene
The measurement method of larger diameter internal bore is measured, the convenience for device maintenance of measurement inner hole, light, dynamometry is small and easy to operate to reach
Purpose needs to design a kind of large diameter hole calipers.
Utility model content:
The utility model is intended to overcome the deficiencies of existing technologies, and provides that a kind of structure is simple, performance is stable, measurement is accurate
Large diameter hole calipers.
In order to solve the above-mentioned technical problem, the utility model the following technical schemes are provided:
A kind of large diameter hole calipers, including measuring staff 1, limiting device 2, deformed area 3, stylus 4, skirt guided 5,
It is characterized in that, 1 head of measuring staff is rounded, and 5 outer diameter of skirt guided and measured workpiece internal orifice dimension match, solid in skirt guided 5
Surely there are measuring staff 1, limiting device 2, deformed area 3, stylus 4, stylus 4 passes through skirt guided top center and is installed on deformed area 3；
Measuring staff 1 and tested aperture inner hole are in contact, and measuring staff 1 is mutually flexibly connected with deformed area 3, and limiting device 2 is installed on deformed area 3
Avris controls the overhang of measuring point, and the horizontal displacement that measuring staff 1 passes over is converted to vertical displacement amount by stylus 4.
Further, deformed area 3 uses parallelogramming deflection structure, and the displacement of measuring staff 1 is passed by mechanism 1:1
Pass stylus 4.
Further, the indeformable part of deformed area 3 is fixed in skirt guided 5.
Further, it is clearance fit that stylus 4, which moves up and down with the centre bore in skirt guided 5,.
Further, limiting device 2 is fixed on the top of skirt guided 5 by screw.
Compared with prior art, the utility model have it is following the utility model has the advantages that
The utility model has the function of dynamometry major diameter aperture, and simple and light, dynamometry is small, easy to operate, performance
Stablize.It overcomes since guide section is not easy the problem of being inserted into measurement process, skirt guided can accomplish larger with workpiece gap
Without influencing measurement accuracy；Application of the parallelogramming deflection structure in the measuring device overcomes larger diameter internal bore measurement,
The larger problem of dynamometry；The application of limit ensure that the overhang of measuring point, is limited by adjusting, can also effectively extend gauge
Service life；Internal mechanism is simple, from heavy and light, overcomes gauge from great disadvantage；Structure is simple, easy to maintain；
Structure is simple, and performance is stablized.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of utility model large diameter hole calipers.
Fig. 2 is the schematic top plan view of utility model large diameter hole calipers.
Specific embodiment
In order to preferably illustrate the utility model, it is described in detail with reference to the accompanying drawing.
As shown in Figs. 1-2, a kind of large diameter hole calipers, including measuring staff 1, limiting device 2, deformed area 3, stylus 4,
Skirt guided 5,1 head of measuring staff is rounded, guarantees and measured piece is point contact.5 outer diameter of skirt guided and measured workpiece inner hole
Diameter matches, and guarantees point slightly more a little bit smaller than measured hole, guarantees under the positioning of skirt guided 5, and two measuring staffs 1 measure tested work
The stability of part diameter of bore.Measuring staff 1, limiting device 2, deformed area 3, stylus 4, limiting device are fixed in skirt guided 5
2 are fixed on the top of skirt guided 5 by screw.It is clearance fit that stylus 4, which moves up and down with the centre bore in skirt guided 5,.
Stylus 4 passes through skirt guided top center and is installed on deformed area 3；The moveable part of the deformed area measuring staff 1+ 3, the two calculations
It moves together, deformed area 3 uses parallelogramming deflection structure, and the displacement of measuring staff 1 is passed to survey by mechanism 1:1
Needle 4.Measuring staff 1 and tested aperture inner hole are in contact, and measuring staff 1 is mutually flexibly connected with deformed area 3, and limiting device 2 is installed on deformed area 3
Avris control measuring point overhang, the horizontal displacement that measuring staff 1 passes over is converted to vertical displacement amount by stylus 4.Deformation
The indeformable part in area 3 is fixed in skirt guided 5.The effect of limiting device 2 is the deflection in restrained deformation area 3, and deformation is too
It is big easy to be disconnected, the overhang of the prominent skirt guided 5 of measuring point 1 can also be adjusted, overhang is too big, is less susceptible to be put into workpiece
Measured hole.
Action principle: measuring device is inserted into measured hole, skirt guided and inner hole of workpiece contact, plays the work being initially oriented to
With；Measuring point and the contact of tested aperture inner hole；Measuring point is connected with deformed area, and deformed area is deformed using parallelogram principle 1:1；Limit
The overhang of position device control measuring point, guarantees easily operated；The displacement that stylus passes over measuring point is changed to by horizontal direction
Vertical direction.
It the foregoing is merely the embodiments of the present invention is illustrated, is not intended to limit the utility model, for ability
For the technical staff in domain, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement
Deng should be included within the scope of protection of this utility model.
