Abstract
The utility model relates to a move the three -coordinate measuring machine structure, especially an automatic three -coordinate measuring machine sectional type guide rail mechanism. This mechanism includes a work platform, and work platform one side is equipped with can follow the gliding head tree of work platform, and the head tree top is connected in the one end of a crossbeam, installs Z axle mechanism on the crossbeam, Z axle mechanism include Z axle stand and locate the vertically linear guide on the Z axle stand, linear guide be the sectional type structure formed by the multistage guide rail, the multistage guide rail in be equipped with the clearance between adjacent two sections guide rails. The utility model discloses a through segmenting the intercepting to linear guide, the temperature located when the machine is when great changes will take place, leaves proper amount clearance between each section guide rail, can effectual release because deformation that the temperature was brought, very big reduction the machine because the change of temperature and the influence that brings to the precision of machine is greatly improved.
Description
Technical field
The utility model relates to a kind of three coordinate measuring machine structure automatically, especially a kind of three coordinate measuring machine sectional type guide rail mechanism automatically.
Background technology
Along with the development of modern precision processing and manufacturing technology, increasing product is also increasingly strict to the requirement of precision, traditional metering system and instrument, such as: the instruments such as tape measure, slide calliper rule, clock gauge, do not reach the requirement that Product Precision is measured far away, in order to solve the geometric detection of some complex products, three coordinate measuring machine has arisen at the historic moment.Three coordinate measuring machine is a kind of fine measuring instrument of three-dimensional dimension, is mainly used in the detection of element size, shape and mutual alignment.Based on three-dimensional coordinates measurement principle, the measurement space of three coordinate measuring machine is placed in by testee, the coordinate position of each measuring point on testee is obtained by gauge head, according to the spatial value of these points, through the mathematical operation of Survey Software, obtain tested physical dimension, shape and position, judge whether test product reaches in the margin tolerance that marks of processing drawing.Three coordinate measuring machine is mainly used in the fields such as automobile, mould cubing, Aero-Space, military project.
Mainly contain following several at automatic three coordinate measuring machine Y-axis drive mechanism:
1, Timing Belt adds air-bearing shafts bearing structure, and advantage is that precision is high, is easy to regulate.Shortcoming is that do not have source of the gas to work, rigidity is bad by measuring environmental restraint;
2, leading screw adds line slideway, and advantage is good rigidly, and positioning precision is high, when can work without when source of the gas.Shortcoming is that noise is large, and the bad grasp of assembly technology, manufacturing cost is high.
Summary of the invention
The purpose of this utility model solves the deficiencies in the prior art, provides a kind of three coordinate measuring machine sectional type guide rail mechanism automatically.
To achieve these goals, the utility model adopts following technical scheme:
It comprises a workbench, workbench side is provided with the head tree that can slide along workbench, one end of a crossbeam is connected to above head tree, crossbeam is provided with Z-axis mechanism, described Z-axis mechanism comprises Z axis column and the vertical line slideway be located on Z axis column, its improvement is: described line slideway is the segmentation structure be made up of multistage guide rail, is provided with gap between two sections of guide rails adjacent in described multistage guide rail.
Owing to have employed such scheme, automatic three coordinate measuring machine sectional type guide rail mechanism of the present utility model can run under the environment not having source of the gas, does not need airtight measuring chamber, can directly use in production scene; By carrying out segmentation intercepting to line slideway, when great changes will take place for the temperature residing for machine, there is deformation hardly in guide rail, appropriate gap is left between each section of guide rail, effectively can discharge the deformation brought due to temperature, the pedestal generation deformation of machine can not be made because the pedestal of machine is different from the material of guide rail, greatly reduce the impact that machine brings due to the change of temperature, thus substantially increase the precision of machine.
Accompanying drawing explanation
Fig. 1 is the one-piece construction schematic diagram of the utility model embodiment;
Fig. 2 is the Z-axis mechanism structural representation of the utility model embodiment;
Fig. 3 is the guide rail structure schematic diagram of the utility model embodiment.
Embodiment
As shown in Figure 1-Figure 3, automatic three coordinate measuring machine sectional type guide rail mechanism described in the present embodiment comprises a workbench 1, workbench 1 side is provided with the head tree 2 that can slide along workbench, one end of a crossbeam 3 is connected to above head tree 2, crossbeam 3 is provided with Z-axis mechanism, described Z-axis mechanism comprises Z axis column 4 and the vertical line slideway 5 be located on Z axis column 4, described line slideway 5 is the segmentation structure be made up of multistage guide rail, is provided with gap 6 between two sections of guide rails adjacent in described multistage guide rail.
During work, appropriate gap 6 is left between each section of guide rail, effectively can discharge the deformation brought due to temperature, the pedestal generation deformation of machine can not be made because the pedestal of machine is different from the material of guide rail, greatly reduce the impact that machine brings due to the change of temperature.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model instructions and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
