Summary of the invention
The present invention provides a kind of gantry combined by guide beam with load-bearing driving beam for gantry measuring machine crossbeam design structure
The double crossbeam design structures of measuring machine, are able to solve big, the at high cost problem of large scale type enforcement difficulty.
In order to achieve the above objectives, the technical solution adopted by the present invention is that: it is a kind of to be combined with load-bearing driving beam by guide beam
Measuring machine double crossbeam design structures in gantry are mechanically connected including guide beam, air cushion, with the guide beam by the air cushion
YZ axis balladeur train, be mechanically connected with the YZ axis balladeur train Z axis speed reducer, with the YZ axis balladeur train pass through the air cushion
The Z axis of mechanical connection, the driving guide rail being mechanically connected with the load-bearing driving beam, is led with the driving load-bearing driving beam
The drive seat of rail mechanical connection, the balance weight mechanism being mechanically connected with the drive seat, the Y being mechanically connected with the drive seat
Axis speed reducer, it further include X-axis slide connecting plate, wirerope, it is characterized in that: design method is driven using Y, Z axis guiding with load-bearing
It is dynamic that frame mode, the guide beam and the load-bearing driving beam two are independently performed by guide beam and load-bearing driving beam respectively
Connection is installed by the X-axis slide connecting plate in end in parallel, and the drive seat passes through two spherical end surfaces and the YZ axis
The connection of balladeur train both ends of the surface slide fit drives the YZ axis balladeur train and described when the drive seat is along the described driving guide rail operation
Z axis moved together along the guide beam, the Z axis is driven through the YZ axis balladeur train by the Z axis speed reducer
Operation up and down, the Z axis and the YZ axis balladeur train are connect by the wirerope with the balance weight mechanism, described
The weight that load-bearing driving beam passes through the balance weight mechanism carrying Z axis and the YZ axis balladeur train.
Due to the application of the above technical scheme, the present invention beneficial effect that it is generated compared with prior art is: design side
The advantages of method is independently performed frame mode by guide beam and load-bearing driving beam respectively with load-bearing driving using Y, Z axis guiding is:
The function of guide beam is mainly the guiding accuracy for guaranteeing YZ axis balladeur train in design structure, does not carry Z axis, YZ axis balladeur train and counter weight machine
The weight of structure and driving to YZ axis balladeur train, are greatly reduced intensity requirement, and the function of load-bearing driving beam mainly completes carrying Z
The driving of axis, the weight of YZ axis balladeur train and balance weight mechanism and YZ axis balladeur train, it is lower to required precision, it designs compared with prior art
Implement relatively easily, can effectively solve the problems, such as that large scale gantry measuring machine enforcement difficulty is big, at high cost.

Specific embodiment
Referring to attached drawing 1, a kind of double crossbeam design structures of gantry measuring machine combined by guide beam with load-bearing driving beam, including
The Z axis speed reducer for YZ axis balladeur train and YZ axis the balladeur train mechanical connection that guide beam, air cushion and guide beam are mechanically connected by air cushion,
The Z axis that is mechanically connected with YZ axis balladeur train by air cushion, load-bearing driving beam, with the driving guide rail of load-bearing driving beam mechanical connection, with
It drives the drive seat of guide mechanism connection, slow down with the balance weight mechanism of drive seat mechanical connection, with the Y-axis of drive seat mechanical connection
Machine, it further includes X-axis slide connecting plate, wirerope, and guide beam (Y-axis) and Z axis are air-float guide rail structure, driving in design structure
Guide rail is installed in parallel in load-bearing driving beam upper surface using linear guide, and guide beam and load-bearing driving beam both ends pass through X-axis slide
Connecting plate install in parallel connection (to avoid the deformation of load-bearing driving beam from having an impact guide beam, load-bearing driving beam and guide beam
Connection one end is directly to be fixedly connected, and the other end is to be connect by guide rail slide with X-axis slide connecting plate), drive seat is mounted on
It drives on guide rail slide block, drive seat both ends are connect by two spherical end surfaces with YZ axis balladeur train both ends of the surface slide fit, when drive seat is along drive
When dynamic guide rail operation, two spherical end surfaces drive YZ axis balladeur train and Z axis to move together along guide beam, and Z axis passes through rack pinion
Mechanism is run up and down by air cushion of the Z axis speed reducer driving through YZ axis balladeur train, and Z axis is connected by wirerope and air cylinder structure balance weight mechanism
It connects, YZ axis balladeur train is connect by wirerope with heavy hammer structure balance weight mechanism, and balance weight mechanism is mounted in drive seat, load-bearing driving beam
The weight of Z axis and YZ axis balladeur train is carried by balance weight mechanism.The function of guide beam mainly guarantees YZ axis balladeur train in design structure
Guiding accuracy, do not carry Z axis, the weight of YZ axis balladeur train and balance weight mechanism and the driving to YZ axis balladeur train, it is big to intensity requirement
Width reduces, and the function of load-bearing driving beam is mainly to complete the weight and YZ axis balladeur train of carrying Z axis, YZ axis balladeur train and balance weight mechanism
Driving, required precision is lower, the influence very little generated when operation to guide beam precision, realizes gantry measuring machine Y, Z axis guiding
The design structure being respectively completed by two independent crossbeams is driven with load-bearing, so that opposite hold is implemented in measuring machine design in large scale gantry
Easily, manufacturing cost reduces.
