Problems solved by technology

Large-scale caliper measurement: it is very cumbersome to operate, the accuracy is very low, and the measured data is inaccurate; the comparative measurement method currently used is usually to use a standard block combined into a length close to the size of the workpiece to be measured as a calibration reference. It is not accurate enough, and the length resolution is very low, it cannot be combined into any size, and the combination of process standard blocks is easy to deform, which has a great impact on the detection accuracy

Embodiment 1

[0036] like Figure 1-3 The horizontal intelligent length reference instrument shown includes the upper computer 8, the main workbench 1, the additional workbench 2 and the screw transmission unit. The main workbench 1 and the additional workbench 2 are made of marble. A marble support 15 is provided, and the marble support 15 is fixedly connected to the main workbench 1 by support bolts 16 .

[0037]The additional workbench 2 and the screw drive unit are installed in parallel on the main workbench 1 respectively. The grating ruler 19 is installed on the additional workbench 2. The grating ruler 19 is pasted on the additional workbench 2. Both ends of the grating ruler 19 are fixed. There is a grating ruler pressing block 21, and the screw drive unit includes a slide rail 9, a lead screw and a screw nut. The head of the slide rail 9 is fixedly equipped with a fixed measuring block 25, and a moving measuring block 26 is slidably installed on the slide rail 9 for fixed measureme...

Embodiment 2

[0062] The intelligent length reference instrument in this embodiment is basically the same as that in Embodiment 1, the difference is that the upper computer adopts an operating system with intelligent human-computer interaction, and the operating system has functions such as guiding the user to establish a length reference and performing automatic error compensation , the operating system of the length reference instrument in the host computer includes the following modules:

[0063] (1) Intelligent guidance module: through the human-computer interaction interface, the user is guided to perform zero calibration at startup, automatically, and guides the user to establish the length reference according to the steps designed by the system;

[0064] (2) Error compensation module: including the grating ruler length automatic correction module and the temperature compensation module; the grating ruler length automatic correction module automatically and synchronously collects the d...

Abstract

The invention relates to the field of length measuring and especially relates to a length calibration instrument. Provided is a horizontal intelligent length reference instrument comprising a host computer, a master work platform, an additional work platform and a lead screw transmission unit. The additional work platform and the lead screw transmission unit are parallel and are installed on the master work platform. A grating ruler is installed on the additional work platform. The lead screw transmission unit comprises a slide rail, a lead screw and a nut, wherein a fixed measuring block is fixed and installed on the head of the slide rail, a movable measuring block is slidingly installed on the slide rail, and the movable measuring block is fixed on the nut; a grating ruler read head is installed on the movable measuring block and is positioned above the grating ruler, wherein the grating ruler read head and the grating ruler are parallel to each other. An output end of the grating ruler read head is electrically connected with the host computer. The lead screw is connected with one output shaft of a servo motor. The servo motor is electrical connected with a PLC through a servo driver and the PLC is electrically connected with the host computer. By means of the length reference instrument, the length reference of any dimension from 0 to 4000mm can be established, reference precision is guaranteed, and measuring efficiency is greatly increased.

Description

technical field [0001] The invention relates to the field of length measurement, in particular to a length calibration instrument. Background technique [0002] Machining large-scale products, the detection method usually adopts large-scale caliper measurement and comparative measurement method during mass production. Large-scale caliper measurement: it is very cumbersome to operate, the accuracy is very low, and the measured data is inaccurate; the comparative measurement method currently used is usually to use a standard block combined into a length close to the size of the workpiece to be measured as a calibration reference. It is not accurate enough, and the length resolution is very low, and it cannot be combined into any size. The combination of process standard blocks is easy to deform, which has a great impact on the detection accuracy. Contents of the invention [0003] In order to solve the problems existing in the prior art, the present invention proposes a hor...
