Abstract
The invention discloses a vernier caliper reading number amplifying device which comprises a vernier caliper and an amplifying device that is mounted on the vernier caliper. The amplifying device is provided with a clamping board, an inverse-L-shaped bracket, an amplifier and a positioning fastening assembly. The clamping board is arranged on an auxiliary ruler of the vernier caliper. An inverse-L-shaped bracket trough is arranged behind the clamping board. The vertical frame of the inversed-L-shaped bracket is arranged in the bracket trough, and the upper cross rod of the inversed-L-shaped bracket is movably connected with the amplifier through the positioning fastening assembly. The positioning fastening assembly is used for fastening and positioning the amplifier. The amplifying device can move along with the auxiliary ruler of the vernier caliper and furthermore the rotation angle of the amplifying device can be adjusted. The vernier caliper reading number amplifying device has advantages of simple structure, convenient assembling, convenient operation, clear identification and reading for measured numbers on the reticle of the auxiliary ruler and the reticle of a main ruler. Furthermore the accuracy of the data measured by the vernier caliper is improved.
Description
Technical field
The present invention relates to measurer, be specifically related to a kind of vernier caliper reading multiplying arrangement.
Background technology
Vernier caliper is broad-spectrum conventional measurer in enterprise, it is mainly used in the width of measuring workpieces, external diameter, internal diameter and depth dimensions, in measuring process, it reads measured value by the scale mark on main scale and secondary chi, main scale groove reading is round values, secondary chi groove reading is fractional value, and the reading of fractional value must be found out secondary chi groove with certain groove on main scale and aligns, its numerical value can be read, because this scale mark is similar to other scale mark, in actual measurement, due to the reason of people's eye eyesight feel resolving power, be difficult to accurately find out, in working site, sometimes a few people can read several numerical value, measurement result is easily caused to cause the inaccurate of measurement data due to the mistake of reading.Therefore existing vernier caliper technology is in actual testing, also exists and measure numerical value difficulty and read, reading inaccurate depending on reading defect, the accuracy that can need improve in testing its improvement.
Summary of the invention
The object of the present invention is to provide that a kind of structure is simple, assembling and easy to operate, easy identification and read the multiplying arrangement of vernier caliper reading, to improve the accuracy of vernier caliper measurement numerical value.
For achieving the above object, vernier caliper reading multiplying arrangement of the present invention, comprises vernier caliper and establishes multiplying arrangement thereon, it is characterized in that: described multiplying arrangement is provided with clamp, " Γ " shape support, magnifier and positioning and fastening assembly; Described clamp is arranged on the secondary chi of vernier caliper, and the vertical frame of described " Γ " shape support is arranged in the bracket groove at clamp rear, and top cross bar is flexibly connected with magnifier by positioning and fastening assembly.
Be provided with two groups of claws above described clamp, below arranges one group of claw, claw has interior dog clutch;
The vertical frame of described " Γ " shape support is flat bar, and cross bar is cylindrical and is provided with screw thread;
Described positioning and fastening assembly is made up of setscrew nut, spring and spiral cover, and described spring is arranged in spiral cover;
Described magnifier can be that axis rotates with the cross bar of " Γ " shape support.
In technique scheme, owing to being provided with clamp, " Γ " shape support, magnifier and positioning and fastening assembly on multiplying arrangement; Described clamp is arranged on the secondary chi of vernier caliper, and the vertical frame of described " Γ " shape support is arranged in the bracket groove at clamp rear, top cross bar is provided with magnifier and positioning and fastening assembly.After taking said structure, the multiplying arrangement be arranged on secondary chi can move with secondary chi, and visible resolution is improved in measuring process, can clearly identify and read secondary chi and the indicating value corresponding to main scale groove, to improve and to ensure the accuracy of vernier caliper measurement numerical value.
Further, be provided with two groups of claws above described clamp, below arranges one group of claw, claw has interior dog clutch, to facilitate and firmly to make clamp be arranged on the secondary chi of vernier caliper;
Further, described " Γ " vertical frame of shape support is flat bar, be arranged on to facilitate in " Γ " shape bracket groove, cross bar is cylindrical and is provided with screw thread, to be connected with positioning and fastening assembly;
Further, described positioning and fastening assembly is made up of setscrew nut, spring and spiral cover, and described spring is arranged in spiral cover, to facilitate in the process screwed location and to tighten up magnifier;
Further, described magnifier can be that axis rotates with the cross bar of " Γ " shape support, according to measurement needs, to regulate the anglec of rotation of magnifier.
