Description

TECHNICAL FIELD

[0001] The present application relates to bridge type three coordinate measuring machine mechanical structure technology BACKGROUND

[0002] In the prior art, the bridge type three coordinate measuring machine structure generally adopts the structure that the main column and the auxiliary column are connected by the screw and the cross beam is installed on the working platform through the guide rail, the Z-axis assembly is installed on the cross beam, and the movement of the machine in the platform direction is realized by the driving device installed on one side of the main column.

[0003] The problem of the prior art is that, since the movement of the bridge type three coordinate measuring machine in the platform direction is realized by the driving operation of the main column on one side, the main column needs to overcome the inertial torque generated in the horizontal direction when the machine accelerates or decelerates, if the guide rail adopts the granite material, the machine is heavy, and the connection stiffness of the main column and the guide cross beam limits the acceleration of the machine, thereby affecting the measurement efficiency. SUMMARY

[0004] The present application provides a bridge type three coordinate measuring machine with a center driving integral bridge seat structure, which can solve the measurement efficiency problem of the bridge type three coordinate measuring machine with the guide rail adopting the granite material.

[0005] To achieve the above-mentioned purpose, the technical scheme adopted by the present application is that the bridge type three coordinate measuring machine with the center driving integral bridge seat structure comprises a guide platform, an integral bridge seat, a working platform, a Y-axis sliding seat and a Z-axis assembly, and further comprises a linear guide rail, a linear motor stator and a linear motor rotor, the integral bridge seat is an integral structure composed of a main column, an auxiliary column, a base and a cross beam, is installed on the linear guide rail of the guide platform through the base, the Y-axis sliding seat is installed on the linear guide rail of the cross beam of the integral bridge seat, and the Z-axis assembly is installed on the Y-axis sliding seat.

[0006] The linear motor stator is installed at the middle position of the plane of the guide platform, the linear motor rotor is installed at the position corresponding to the linear motor stator below the base of the integral bridge seat, and the linear motor pushes the integral bridge seat to run along the linear guide rail on the guide platform.

[0007] The working platform is installed on the guide platform through the support at both ends.

[0008] Due to the use of the above technical scheme, the bridge type three coordinate measuring machine with the center driving integral bridge seat structure is realized by the linear motor driving at the middle position of the base of the integral bridge seat, the inertial torque generated in the horizontal direction when the machine accelerates or decelerates is very small, and the measurement efficiency problem of the bridge type three coordinate measuring machine with the guide rail adopting the granite material can be effectively solved.

[0014] Referring to FIGS. 1, 2, and 3, Figure 1 FIG. 1 is a schematic diagram of the structure of the present application. Figure 2 FIG. 1 is a schematic diagram of the structure of the present application. Figure 3 The bridge-type three-coordinate measuring machine with a center-driven overall bridge seat structure includes a guide platform, an overall bridge seat, a working platform, a Y-axis slide, and a Z-axis assembly. It also includes a linear guide, a linear motor stator, and a linear motor rotor. The overall bridge seat is a monolithic structure composed of a main column, an auxiliary column, a base, and a crossbeam. It is installed on the linear guide of the guide platform through the base. The Y-axis slide is installed on the linear guide of the crossbeam of the overall bridge seat. The Z-axis assembly is installed on the Y-axis slide. The linear motor stator is installed at the middle position of the plane of the guide platform. The linear motor rotor is installed at the position corresponding to the linear motor stator below the base of the overall bridge seat. The linear motor drives the overall bridge seat to run along the linear guide of the guide platform. The working platform is installed on the guide platform through support at both ends.

[0015] When the linear motor drives the overall bridge seat to run along the guide platform, since it is center-driven, it is basically consistent with the position of the center of gravity of the machine. Therefore, when the machine accelerates or decelerates, the inertial torque generated in the horizontal direction is very small. The linear guide made of granite material can also achieve high-efficiency measurement.
