Abstract
The utility model relates to a linearity testing device for a machine tool, which is formed by improving the existing steel wire microscope testing device. The utility model is composed of two steel wire fixing adjustors and a spring ergometer, wherein each steel wire fixing adjustor is composed of a front adjusting slide block, a back adjusting slide block, a bidirectional vertical adjusting slide block, an adjusting bolt and a clip ring, and the spring ergometer is connected in series between the two steel wire adjustors. Therefore, the utility model can be used for testing the machine tool provided with an inclined body, has the characteristics of high testing precision, high testing speed and low cost, and is especially suitable for testing a digital control lathe.
Description
The utility model relates to a kind of linearity testing apparatus, particularly lathe straight-line detection device.
Existing linearity testing apparatus generally is divided into two classes: a class is a mechanical type, as examines rod, leveling ruler, steel wire microscope etc., and another kind of is the pick-up unit that light, electronic package constitute, as laser detection system.When detecting general lathe, this two classes pick-up unit respectively has relative merits.According to various countries' examination criteria such as ISO/R230-1962, JB4369-86, regulation such as JISB6331(1986): maximum machining length or range detect with the excellent leveling ruler of inspection during less than 1 meter, during greater than 1 meter with steel wire microscope or laser detection system.Existing steel wire microscope is because the enamel sign indicating number as the steel wire tightening force, so be subject to the extraneous vibration influence, adjust the also inconvenience of steel wire position, so detection efficiency is low.The steel wire tightening force can not accurately be measured, and steel wire is subjected to gravity effect and the amount of deflection and the tightening force that produce have direct relation, therefore can not accurately calculate the steel wire amount of deflection, this machine tool applications problem at the light water level gauge is also little, and it is just improper detection to be had a numerically-controlled machine of oblique lathe bed.Can accurately detect with laser detection system, but its pick-up unit costliness, and also use cost is also very high, therefore is difficult to popularize.
The purpose of this utility model provides a kind of lathe linearity testing apparatus, can overcome the deficiencies in the prior art, and easy to use, cost is low, detects accurately.
The technical solution of the utility model by two covers respectively with front and back are adjusted piece, adjusted rest pad, two-way vertical adjustment slide block and adjustment bolt, spring collar are formed fixation with steel wire regulator and steel wire, reading microscope and be serially connected with steel wire and the fixation with steel wire regulator between spring dynamometry table etc. form.In order to measure in principal plane and two planes of secondary flat, reading microscope is fixed on the microscope stand of being made up of pole, pillar and adjustment nut.When detecting lathe, be installed in two cover fixation with steel wire regulators in the machine tool chief axis hole respectively and tailstock mandrel hole in, mobile tailstock mandrel applies pulling force to steel wire, reads the accurate numerical value of pulling force from precision spring dynamometry table, can calculate the amount of deflection of steel wire with this value.Because the damping action of spring dynamometry table, steel wire vibrates insensitive to external world, so reading microscope can adopt than high magnification, helps improving accuracy of detection.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is the cut-open view of the utility model in detecting the machine cut principal plane.
Fig. 2 is the vertical view of Fig. 1.
The sectional view that Fig. 3 is the utility model when detecting oblique lathe bed lathe.
Describe concrete structure of the present utility model in detail according to Fig. 1-3, steel wire 15 two ends of this device are installed on spring dynamometry table 2 and the preceding adjustment slide block 18 by lifting bolt 1 respectively, spring dynamometry table 2 is adjusted slide block 3, two-way vertical adjustment slide block 4, is adjusted rest pad 6 and be installed in the tailstock mandrel 7 with self-locking circular cone handle 8 by the back, by two adjust bolt 5, circlips 9 adjust respectively steel wire 15 in the principal plane of lathe afterbody with secondary flat in the position.Be fixed in circular cone handle 17 on the main shaft 16 also by the position of adjusting rest pad 6, two-way vertical adjustment slide block 4, preceding adjustment slide block 18, adjusting bolt 5, circlip 9 is adjusted head of a bed part steel wire 15, make itself and machine tool chief axis line coincidence or parallel.By being installed on pole 11,13 and the pillar 19 on the knife rest 10, adjusting nut 20 and fixing reading microscope 14.When detection had the numerically-controlled machine of slant rail, as shown in Figure 3, reading microscope 14 was installed on the tool holder system 21, can slide on guide rail 22 with it, by the observation in A-A principal plane and B-B secondary flat, can measure the linearity of lathe.The utility model also can be used for detecting the linearity of a lathe bed.
Use the utility model because easy to adjust, the detection efficiency height, cost of the present utility model is low, be convenient to popularize, the accuracy of detection height, go out the steel wire amount of deflection as calculated after, the actual detected precision can meet or exceed the precision with the inspection rod.
