Abstract

The utility model relates to a disc thickness measuring instrument, which comprises a measuring base, a measuring arm and a precise altimeter and is characterized in that the measuring base takes theL shape; a disc center fixing column is fixedly connected with the end part of horizontal end of the measuring base; one end of the measuring arm is arranged in a horizontal hole of the vertical end of the measuring base and can move back and forth for adjustment; and the other end of the measuring arm is fixedly connected with the vertical precise altimeter. The disc thickness measuring instrument has the advantages that the structure is simple, and the operation is very convenient; the center hole of the disc is only sheathed on the fixing column by the operator, then the measuring arm is adjusted by rotating the disc or leading the disc to move back and forth, the thickness of every spot of the disc is measured, and the measured thickness reading data is displayed directly on a digitaldisplay screen of the precise altimeter, therefore, both the operation and the data reading are convenient, and the efficiency is high. In addition, the disc thickness measuring instrument has pure mechanical structure, low cost, simple maintaining and good firmness and durability.

Description

The disk thickness measuring instrument

Technical field

The utility model relates to a kind of tool for measuring thickness, is specifically related to be used for the measuring instrument that disk thickness is measured.

Background technology

Make rapid progress in computing machine science and technology, the constantly progressive epoch, data in many computing machines in use or operation when finishing, all need data is done storage, and the mode of the data of storage computation machine, all used 1.44 in the past " or 3.5 " disk sheet store, be difficult for to preserve the defective of finite capacity but disk sheet has.The application software of larger capacity just needs many disks to come separate storage, and cost height, the disk sheet of depositing are made and required height, and cost is big.Because CD (being called video disc again) can deposit a large amount of data or content of multimedia in, preservation simultaneously is also relatively easy, so optical disc production already comes data on file to obtain bigger development with CD in recent years.

Because CD is the thin disk that a diameter is about 120mm, the homogeneity of disk thickness will have influence on CD-ROM drive or other players and can read CD and broadcast with normal speed.In order to guarantee the quality of CD, so be necessary accurately to measure the thickness of CD each point position during quality check.Current measuring methods is to use the thickness of vernier caliper hand dipping CD.This method has following deficiency: (1) can only measure the thickness of CD outmost turns with vernier caliper, can not measure the thickness of CD interior zone and central region, can not investigate the homogeneity of overall optical disc thickness.(2) because CD is a thin disk, too much during the bayonet socket measuring light dish sheet of vernier caliper with the optical disc surface contact point, can not accurately represent the thickness of certain point of CD, variation tendency that simultaneously can not the measuring light disc thickness.

The utility model content

The purpose of this utility model is: a kind of simple in structure, sturdy and durable, disk thickness measuring instrument that cost is low is provided, can makes things convenient for the thickness of accurately measuring various CDs fast, and can regulated at will measurement point position.

In order to achieve the above object, the technical scheme that adopts is: a kind of thickness measurement equipment of CD, comprise and measure base, gage beam and precise height table, it is characterized in that: described measurement base is L-shaped, the cd center hole fixed leg is fixedlyed connected with the end of described measurement base horizontal ends, one end of gage beam places the level of described measurement base vertical end to the hole, and can move forward and backward adjusting, the other end of described gage beam with vertical to the precise height table fixedly connected.

The utility model disk thickness measuring instrument has following advantage: simple in structure, operation is very easy, the surveyor only needs cd center hole to be measured is enclosed within on the fixed leg, can and move forward and backward by rotary CD then and regulate described gage beam, measure the disk thickness of each some position; The thickness reading that records directly is presented on the digital display screen of precise height table, and the operation reading is all very convenient, high efficiency.

Description of drawings

Fig. 1 is the utility model user mode structural representation;

Fig. 2 is that the A of Fig. 1 is to structural representation.

Among the figure, the 1-CD; 2-cd center hole fixed leg; 3-measures base; The 4-hole; The 5-gage beam; The 6-height indicator.

Embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

By Fig. 1,2 as seen, a kind of thickness measurement equipment of CD, comprise and measure base 3, gage beam 5 and precise height table 6, it is characterized in that: described measurement base 3 is L-shaped, cd center hole fixed leg 2 is fixedlyed connected with the end of described measurement base 3 horizontal ends, one end of gage beam 5 places the level of described measurement base 3 vertical end to hole 4, and can move forward and backward adjusting, the other end of described gage beam 5 with vertical to precise height table 6 fixedly connected.

During use: the tester opens precise height table 6 power switch, after the probe of affirmation precise height table 6 gently is pressed on the upper surface of measuring base 3, by zero zero-bit is set.The CD 1 for the treatment of Thickness Measurement by Microwave is enclosed within on the cd center hole fixed leg 2, and the probe of precise height table 6 is pressed in CD 1 surface, at this moment read the numerical value of precise height table 6 be one-tenth-value thickness 1/10 at precise height table 6 probe place CD 1.Then, can pass through rotary CD 1, measure on the radius of the probe place of height indicator 6, the one-tenth-value thickness 1/10 of this CD 1 each some position.Or, measure the one-tenth-value thickness 1/10 of CD 1 on the different radii by regulating gage beam 5 extension elongations.

This disk thickness measuring instrument also is applicable to dissimilar CDs, and the length that only needs to regulate gage beam 5 gets final product.

The utility model is that stainless steel forms through Precision Machining, pure physical construction, and cost is low, maintaining is simple, and sturdy and durable, not fragile.The quality monitoring personnel can make things convenient for the thickness distribution of confirming CD fast, thereby can be according to the running status of the rapid conditioning equipment of measurement result.

Claims

1. disk thickness measuring instrument, comprise and measure base (3), gage beam (5) and precise height table (6), it is characterized in that: described measurement base (3) is L-shaped, cd center hole fixed leg (2) is fixedlyed connected with the end of described measurement base (3) horizontal ends, one end of described gage beam (5) places the level of described measurement base (3) vertical end to hole (4), and can move forward and backward adjusting, the other end of described gage beam (5) with vertical to precise height table (6) fixedly connected.
