As shown in Figure 1, in the prior art, digital display calliper commonly used comprises main scale, vernier, measuring claw, gauge head, drives structure, digital display module, main scale is flat-shaped, main scale and vernier are slidingly connected, and main scale is fixedlyed connected with the location survey measuring jaw, and vernier is fixedlyed connected with moving measuring claw, two measuring claw coplanes and parallel with main related scale, the terminal outside of measuring claw is provided with gauge head; The digital display module comprises display structure and button, and the digital display module is fixed on the vernier.
The plane parallel of the reading plane of common digital display calliper and the extension direction of measuring claw, this structure need to adjust sight angle and come reading, inconvenient operation when measuring the wheel hub type objects; Secondly, when removing to measure the wheel hub internal diameter with common slide calliper rule, because slide calliper rule posture in measurement is stable inadequately, gauge head is difficult to find the hub diameter point when measuring at every turn, thereby causes measuring the generation error.
Summary of the invention
The utility model purpose provides a kind of digital display calliper of measuring wheel hub type objects internal diameter, and this kind of calliper accurately and make things convenient for reading.
For achieving the above object, the technical solution adopted in the utility model is: a kind of digital display calliper that is used to measure the wheel hub internal diameter, comprise main scale, vernier, location survey measuring jaw, moving measuring claw, drives structure and digital display module, main scale and vernier are slidingly connected, main scale is fixedlyed connected with the location survey measuring jaw, vernier is fixedlyed connected with moving measuring claw, the display window of described digital display module and main related scale be arranged in parallel, angle between described location survey measuring jaw and plane, moving measuring claw place and main related scale is spent greater than 45, and is positioned at the below of described digital display module displays window; Be provided with the maximal value tracking module in the described digital display module.
Above, owing to have certain included angle between measuring claw and chi face, thereby reading easily in the measuring process.
Optimized technical scheme, the angle between described location survey measuring jaw and plane, moving measuring claw place and main related scale are 90 degree.
In the technique scheme, fixed handle is set on main scale, on vernier, is provided with and stirs handle as drives structure; The end of main scale is provided with block, can prevent that vernier from skidding off main scale.
Further technical scheme for guaranteeing the accuracy of measurement and positioning, is respectively equipped with gauge head outside the end of described location survey measuring jaw and moving measuring claw, and the measuring point of two gauge heads is positioned on the straight line parallel with main related scale.Ultimate principle of the present utility model is: when measuring wheel hub type objects internal diameter, the main scale of this digital display calliper is lain on the wheel hub, blade is adjacent to the wheel hub end face, the measuring point of two gauge heads is contacted with inwall, because the line of two measuring points is parallel with main related scale, therefore can guarantee that the position at two measuring point places is on the xsect vertical with the wheel hub axis, improve the accuracy of measuring.
Further technical scheme, the digital display module comprises display structure and button, display structure can be selected light emitting diode or two kinds of forms of liquid crystal display for use.By the interior software of establishing, can realize the maximal value following function, promptly, on the xsect vertical, measure in the internal diameter with the wheel hub axis, the diameter of wheel hub must be maximum in all measurement data, use the maximal value following function, in the process of repeatedly measuring, memory chip is noted measurement data, the data comparison that stores in measured value and the memory chip that computing chip will be each time deposits big data in memory chip, and is presented on the display structure, repeatedly measure and show constantly up to maximal value, institute's value is by being asked internal diameter.The maximal value following function can reduce the operational measure error, improves measuring accuracy.
Because the application of technique scheme, the utility model compared with prior art has the following advantages:
1. because the structure of measuring claw is improved, the measuring claw parallel with main related scale originally changed into main related scale become angle (45～90 degree), be positioned at the display structure below, therefore convenient reading when measuring the wheel hub type objects.
2. measuring claw becomes angle (45～90 degree) and two measurement point on the same straight line parallel with main related scale with main related scale, when therefore measuring the wheel hub type objects, guarantee that measuring point is located on the xsect vertical with the wheel hub axis, thereby improved the accuracy of measuring.
3. adopt the digital display structure, can realize the maximal value tracking, guarantee on the xsect vertical, to find accurate diameter (maximal value) with the wheel hub axis by software.
