The special-purpose three-coordinates measuring machine of wheel loose tool
Technical field
The utility model relates to a kind of three-dimensional coordinates measurement instrument, directly relates to a kind of measuring special-purpose three-coordinates measuring machine of loose tool of taking turns of wheel loose tool that is specifically designed to.
Background technology
Take turns the surveying instrument and the measuring method thereof of the tolerance of loose tool now, on the one hand simple Instrument measuring precision is low, a lot of form and position tolerances are difficult to accurate measurement, though special-purpose its precision of three-coordinates measuring machine of complicated on the other hand wheel loose tool is higher,, not too adapts to and measure annulus class part because three are all linear axis, so its measuring method and data processing are very complicated, efficiency of measurement is lower, and this equipment mostly is import, and it costs an arm and a leg.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, accurate special-purpose three-coordinates measuring machine of wheel loose tool of ring-shaped work pieces tolerance such as measuring wheel loose tool.
The purpose of this utility model is to realize like this, the special-purpose three-coordinates measuring machine of wheel loose tool, comprise base, be installed on the worktable on the base, data acquisition and treating apparatus, upper surface one end of described worktable is equipped with a rotary table, described rotary table is driven by speed change gear by the motor that is installed in the base, the other end of described worktable upper surface is equipped with upright arm, jacking gear by the lifting driven by servomotor is installed in the upright arm, and the slide and the transverse arm of this jacking gear are affixed, transverse arm is provided with by the arm that moves horizontally that moves horizontally driven by servomotor, move horizontally arm and towards the end of worktable gage beam is installed, the free end of gage beam is equipped with measuring head.
The utility model is owing to adopt said structure, the special-purpose three-coordinates measuring machine of wheel loose tool, comprise base, be installed on the worktable on the base, data acquisition and treating apparatus, upper surface one end of described worktable is equipped with a rotary table, described rotary table is driven by speed change gear by the motor that is installed in the base, the other end of described worktable upper surface is equipped with upright arm, jacking gear by the lifting driven by servomotor is installed in the upright arm, and the slide and the transverse arm of this jacking gear are affixed, transverse arm is provided with by the arm that moves horizontally that moves horizontally driven by servomotor, move horizontally arm and gage beam is installed towards the end of worktable, the free end of gage beam is equipped with measuring head, so this utility model is simple in structure, and is cheap.After being placed on ring-shaped work pieces to be measured on the rotary table, by regulating by the jacking gear of lifting driven by servomotor with by the arm that moves horizontally that moves horizontally driven by servomotor, come the control survey head to contact with surface measurements, drive ring-shaped work pieces rotation to be measured by rotary table then, carry out data acquisition and processing by data acquisition and treating apparatus, this utility model measuring method is also very simple, and efficiency of measurement and measuring accuracy are all very high.

Embodiment
As Fig. 1, shown in Figure 2, the special-purpose three-coordinates measuring machine of wheel loose tool comprises base 1, height adjustable support foot 7 is installed below the described base 1, be installed on the worktable 2 on the base 1, data acquisition and treating apparatus comprise computing machine, the horizontal data collector, data acquisition unit up and down, the spin data collector and be installed on the worktable 2 to zero reference piece 6, upper surface one end of described worktable 2 is equipped with a rotary table 3, the upper surface of rotary table 3 is provided with a plurality of grooves 8 concentric with its axis, described rotary table 3 is driven by speed change gear 32 by the motor 31 that is installed in the base 1, the other end of described worktable 2 upper surfaces is equipped with upright arm 4, the jacking gear that is driven by lifting servomotor 41 is installed in the upright arm 4, and the slide of this jacking gear and transverse arm 6 are affixed, transverse arm 6 is provided with by what move horizontally that department's servomotor 42 drives and moves horizontally arm 52, move horizontally arm 52 and towards the end of worktable gage beam 53 is installed, the free end of gage beam 53 is equipped with measuring head 54.
After being placed on ring-shaped work pieces to be measured on the rotary table, by regulating by the jacking gear of lifting driven by servomotor with by the arm that moves horizontally that moves horizontally driven by servomotor, come the control survey head to contact with surface measurements, drive by rotary table then and treat the rotation of gaging hole axle part, carry out data acquisition and processing by data acquisition and treating apparatus, about zero reference piece 6 is used for determining and adjusts, about benchmark zero point, the concentric groove of a plurality of and its axis on rotary table 3 upper surfaces is main as the reference circle of placing tested annular element, described reduction gear 32 can be a gear reducer, accurate worm type of reduction gearing or the described horizontal numerical control collector of other class type speed reducer, data acquisition unit up and down, it can be grating, ball bars etc. are non-from detector line, and spin data collector device refers to rotary encoder.This utility model measuring method is simple, and efficiency of measurement and measuring accuracy are all very high.
The present invention not only can be used for the measuring wheel loose tool, can be used for parts in addition such as measured hole axle class equally.
