Abstract
The utility model relates to a kind of Simple inside diameter milscale, comprise differential calculus ruler, also comprise guide pillar, first locate fixed block, the second location fixed block and measure contact, measurement contact and differential calculus ruler locate fixed block carry on guide pillar respectively by the first location fixed block and second.Compared with prior art, the utility model micrometer inside caliper may be used for measuring the parts internal diameter that endoporus has barrier, and also can be used for the measurement of common endoporus, measurement range is wide simultaneously.
Description
Technical field
The utility model relates to a kind of length measurer, especially relates to a kind of Simple inside diameter milscale.
Background technology
Micrometer inside caliper is of a great variety, and specification is various, of many uses, and the main application of micrometer inside caliper is the instrument of the feature sizes size such as hole, groove measured on part.Especially in manufacturing industry, one of requisite instrument processed by micrometer inside caliper especially part, such as Chinese patent CN 100425942C discloses the luminous inside micrometer in a kind of steam turbine three cylinders jointing and internal sleeve finding, one end of its first cylindrical drum is connected with one end of flexible gauge rod, the other end be fixedly connected with by sleeve with one end of the second cylindrical drum, the other end be connected with the other end of dip stick head, on the outer wall that light emitting diode is fixed on, issued light can be people's finding.But have the inner diameter measurement of barrier at inner bore of part center, especially during large diameter parts measurement, this luminous inside micrometer cannot be measured, and controls parts size precision bring no small difficulty to processing staff.
Market also has the micrometer inside caliper utilizing the arcuate hand grip of outside micrometer to change a social system, but its cost is higher and specification is single, the versatility requirement of plurality of specifications cannot be met.
Summary of the invention
The purpose of this utility model is exactly to overcome the defect and the Simple inside diameter milscale that provides a kind of measurement range wide that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions:
One Simple inside diameter milscale, comprises differential calculus ruler, and also comprise guide pillar, the first location fixed block, the second location fixed block and measure contact, described measurement contact and differential calculus ruler locate fixed block carry on guide pillar respectively by the first location fixed block and second.
Described guide pillar is stainless-steel pipe.
Described first location fixed block and the second location fixed block are aluminium block, and centre is equipped with the through hole worn for guide pillar.
Described first location fixed block is provided with for connecting the first connector measuring contact, and described second location fixed block is provided with the second connector for connecting differential calculus ruler.
Described first connector is provided with the first hole slot worn for measuring contact, described second connector be provided with wear for differential calculus ruler have the second hole slot.
Compared with prior art, the utility model has the following advantages:
1) usable range is wide: the utility model micrometer inside caliper may be used for measuring the parts internal diameter that endoporus has barrier, and also can be used for the measurement of common endoporus, measurement range is wide simultaneously;
2) reliability is strong: guide pillar adopts stainless-steel pipe to process, and not easily gets rusty, is out of shape, and measure portion adopts canonical differential chi, measures accurately, reliably;
3) simple to operate: the width between the part dimension adjustment location fixed block only need measured as required, and then with the calibration of nominal outer diameter milscale, finally carry out measurement just passable, professional training that need not be special;
4) cost-saving: guide pillar, location fixed block all adopt common aluminium to form, and structure is simple, and measure portion adopts the combination of canonical differential chi, greatly reduces enterprise's production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is schematic diagram in the utility model application process;
Wherein: 1, guide pillar, the 2, first location fixed block, 3, measure contact, 4, differential calculus ruler, 5, fixed block clamping screw, the 6, second location fixed block, 7, connector locking bolt.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.The present embodiment is implemented premised on technical solutions of the utility model, give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
A kind of Simple inside diameter milscale, as shown in Figure 1, comprise differential calculus ruler 4, also comprise guide pillar 1, first location fixed block 2, second and locate fixed block 6 and measure contact 3, measurement contact 3 and differential calculus ruler 4 locate fixed block 6 carry on guide pillar 1 respectively by the first location fixed block 2 and second.
Guide pillar 1 is stainless-steel pipe, and the first location fixed block 2 and the second location fixed block 6 are aluminium block, and centre is equipped with the through hole worn for guide pillar 1, and the first location fixed block 2 and the second location fixed block 6 are also equipped with fixed block clamping screw 5.
First location fixed block 2 is provided with for connecting the first connector measuring contact 3, and the second location fixed block 6 is provided with the second connector for connecting differential calculus ruler 4, and the first connector and the second connector are also equipped with connector locking bolt 7.
First connector is provided with the first hole slot worn for measuring contact 3, the second connector be provided with wear for differential calculus ruler 4 have the second hole slot.
As shown in Figure 2, the connector locking bolt 7 outwarded winding in use on the first connector and the second connector, measurement contact 3 and differential calculus ruler 4 are each passed through in the hole slot of the first connector and the second connector, adjust overhang, screw connector locking bolt 7, measurement contact 3 and differential calculus ruler 4 is made to be separately fixed on the first location fixed block 2 and the second location fixed block 6, then two location fixed blocks are inserted on guide pillar 1, the size measuring diameter of part as required adjusts the relative position of two location fixed blocks, the size making measurement contact 3 and differential calculus ruler 4 liang measure claw is less than tested part diameter 0.5-1mm, be locked block clamping screw 5, making two to locate fixed block is fixed on guide pillar 1, then demarcate this Simple inside diameter milscale with outside micrometer and (when can measure initial, measure the spacing of claw outside two, write down the initial scale value on differential calculus ruler 4 shown by fixed sleeving simultaneously, then guide pillar 1 part of this Simple inside diameter milscale is held, rotate the microdrum on differential calculus ruler 4, the measurement claw on measurement contact 3 and differential calculus ruler 4 is made to touch part inwall, rotate the ratchet swing handle of differential calculus ruler 4 again, measurement claw is fully contacted, then scale value shown on fixed sleeving on differential calculus ruler 4 is write down, the difference of the initial scale value of this scale value adds that the measured value of outside micrometer is the internal diameter of tested part.
