Abstract

The utility model provides a three-coordinate measuring machine. The three-coordinate measuring machine is provided with a temperature sensor. The temperature sensor comprises a processor and a probe. The processor is connected with a control system. The probe comprises a shell and a contact sheet. The contact sheet is tightly attached to a pedestal of a main machine. The temperature sensor measures the temperature of the pedestal in real time and transmits data to the control system, and the control system updates a compensation value of a linear expansion coefficient whenever necessary, thereby enabling the measurement results to be more accurate and the measurement precision to be higher.

Description

Three coordinate measuring machine
Technical field
The utility model relates to a kind of three coordinate measuring machine.
Background technology
Present most three coordinate measuring machines both domestic and external all require environment temperature to be controlled at 20 degrees centigrade in use, allow the scope of positive negative variation very little, generally can not be above positive and negative 2 degrees centigrade, otherwise, can't guarantee measuring accuracy owing to three the material and the linear expansion coefficient of measured workpiece material on the three-dimensional coordinates measurement machine host there are differences.Especially be placed on the wide range three coordinate measuring machine in the large space, summer and winter temperature depart from 20 degrees centigrade far away, and temperature fluctuation range is also big, and measuring accuracy just can't guarantee under such environment.For this situation, the way of generally taking at present is by the manual input environment temperature of operator in Survey Software, the temperature of acquiescence measuring machine main frame is consistent with the temperature of measured workpiece, calculate offset by the software in the control system according to the linear expansion coefficient of three coordinate measuring machine three shaft materials and measured workpiece material, control system correcting measuring parameter makes measurement result near actual value.But the way of artificial input temp has several weak points: the one, can only be with reference to the thermometer of outside, and the temperature value of input and the actual temperature value of material have gap, and be not accurate enough; The 2nd, the real-time of input temp value is not strong yet, and the operator can not go the input temp value at any time, and the effect of temperature compensation is bad under the temperature difference fluctuates more frequent environment.
The utility model content
Technical problem to be solved in the utility model provides a kind of three coordinate measuring machine, and the environment temperature of the automatic measurement main frame that this three coordinate measuring machine can be real-time is more timely to the adjustment of linear expansion coefficient offset, makes measurement result more accurate.
The technical scheme that the utility model technical solution problem is adopted is: this three coordinate measuring machine comprises main frame and control system, also comprise temperature sensor, described temperature sensor comprises processor and probe, described processor is connected by cable with described probe, described processor is connected with described control system, described probe comprises housing and is arranged at the contact chip of described housing one end that described contact chip contacts with the pedestal of described main frame.Temperature sensor is measured the temperature of pedestal at any time, and transfers data to control system, generates the linear expansion coefficient offset by control system.
End near contact chip in described housing also is provided with magnet, and magnet is adsorbed on probe on the pedestal, makes contact chip contact better with pedestal.
The other end at described housing also is provided with clamping part, and the clamping part handled easily person take off probe.
The beneficial effects of the utility model are: this three coordinate measuring machine is provided with temperature sensor, can measure the temperature of main frame in real time, and measurement point is three coordinate measuring machine itself, and measured temperature is accurate, error is dropped to minimum.Temperature is measured automatically, feeds back to control system automatically, and control system can real-time update linear expansion coefficient offset, and measurement parameter can be in time, make adjustment exactly.Do not need the operator manually to import, save the labour, avoided the mistake that manual operation produced yet.
Description of drawings
Fig. 1 is the structural representation of the utility model three coordinate measuring machine.
Fig. 2 is the structural representation of the probe of the utility model three coordinate measuring machine.
Embodiment
The linear expansion coefficient compensation principle is, before three coordinate measuring machine is measured testee, in control system 2, import the material and the ambient temperature value of testee earlier, control system 2 is poor according to each polar expansion system with measured workpiece of main frame 1, calculate offset, adjust measurement parameter.Because measured workpiece is placed on the pedestal, it is consistent with main frame 1 residing environment temperature to be defaulted as measured workpiece.
As shown in Figure 1, temperature sensor is set on three coordinate measuring machine, temperature sensor comprises processor 3 and probe 4, and processor 3 is connected with control system 2, and probe 4 is arranged on the pedestal 9 of main frame 1.Probe 4 is surveyed the temperature of pedestal 9, by processor 3 temperature data is transferred to control system 2, and control system 2 is calculated the linear expansion coefficient offset according to said method again.
As shown in Figure 2, probe 4 comprises housing 5 and contact chip 6, and contact chip 6 is preferably copper sheet, and the heat-transfer effect of copper is good, and is easy to process.Contact chip 6 is arranged at an end of housing 5.When measuring temperature, contact chip 6 is adjacent to pedestal 9, can adopt the heat-conducting resin with certain viscosity that contact chip 6 and pedestal 9 are pasted together.Because the pedestal of three coordinate measuring machine and each axle all are to adopt plow-steel, so a kind of better mode is, magnet 7 is set in housing 5, magnet 7 is near contact chip 6, magnet 7 will be popped one's head in and 4 will be adsorbed on the pedestal 9, contact chip 6 and pedestal 9 are tightly sticked together, more help heat conduction, thereby measurement is more accurate.Dependence magnetic force absorption is installed and takes off all very convenient, and the operator can change the position that is provided with of probe 4 quickly and easily, and compares and the mode of pasting with heat-conducting resin, and magnetic force adsorbs cleaner, can not stay any vestige and residue after taking off.
4 to take off from pedestal 9 in order popping one's head in more easily, at the other end of housing 5 clamping part 8 to be set, avoided when magnetic force is big, the operator pulls cable for taking off probe 4, effectively prevents the loosening even disconnection of cable.Clamping part 8 can have various ways, as ring-type, projection, draw ring etc., Figure 2 shows that ring-type.
