The axle automatic measuring machine of the utility model has a high measuring precision, and by adopting the centre locating device, locating precision of the each axle can be ensured, and position locating for repeated measurements also can be ensured.
Description
Technical field
The utility model relates to a kind of locomotive inspection and repair equipment, especially a kind of axletree automatic measurement machine.
Background technology
The axletree automatic measurement machine is used for railway system's wheel shaft and detects the check measurement to the axletree physical dimension, but also do not have this equipment at present, all is to adopt manual measurement, and efficient and precision are low, and waste time and energy.
The utility model content
The utility model provides a kind of axletree automatic measurement machine that can measure the axletree physical dimension automatically.
Realize the axletree automatic measurement machine of the utility model purpose; Comprise base and be fixed on the door-shaped frame on the base; Said base is provided with conveying and positioning device and lifting device; The both sides of said framework are provided with axial length measurement mechanism, caliberating device and top locating device, and the top of said framework is provided with diameter measuring device, and said lifting device is provided with the axletree whirligig.
Said diameter measuring device has two, can on said framework, move around.
The beneficial effect of this practical novel axletree automatic measurement machine is following:
1, measuring accuracy is high
Adopt the magnetic grid horizontal metroscope, carry out direct contact type and measure, remedied the error that mechanical drive produces like this, thereby in whole range ability, can guarantee the measuring accuracy of 2 μ m.
2, adopt top location structure
Guaranteed the bearing accuracy of every axletree, and the location positioning of duplicate measurements.
Description of drawings
Fig. 1 is the structural representation of the utility model axletree automatic measurement machine.
Embodiment
As shown in Figure 1; The axletree automatic measurement machine of the utility model; Comprise base 1 and be fixed on the door-shaped frame 2 on the base 1, said base 1 is provided with conveying and positioning device 4 and lifting device 3, and the both sides of said framework 2 are provided with axial length measurement mechanism 5, caliberating device 7 and top locating device 8; The top of said framework 2 is provided with diameter measuring device 6, and said lifting device 3 is provided with the axletree whirligig.
Said diameter measuring device 6 has two, can on said framework 2, move around.
Diameter measuring device: axletree two ends symmetry is equipped with two groups of measurement mechanisms.Every group of measurement mechanism formed by two magnetic grid horizontal metroscopes, cylinder, linear guides with by the linear movement assembly and the mounting bracket of AC servo machinery driving.
Magnetic grid horizontal metroscope range reaches 100mm, and in whole range ability, can guarantee the precision of 2 μ m, like this, with a pair of magnetic grid horizontal metroscope, just can cover the measurement of multiple axle journal.For the protection gauge head, increase measuring reliability, the gauge head exit structure that has adopted a cover to be made up of stepper motor and linear guides is retreated gauge head in axletree entering process, stretches out measurement after axletree puts in place again.
Linear movement assembly driven by stepper motors drives a pair of gauge head moving axially along axletree; System has worked out corresponding Survey Software according to the disalignment type, and the control survey device rests on axle journal and the dust guard seat diameter of axle, wheel seat diameter, brake disc seat diameter require the section of measurement to measure.
The up-down of axletree and rotation are accomplished by the jacking slew gear.Turning gear rotary shaft ± 120 °.
The axial length measurement mechanism: the measurement of axial length is carried out with the grating chi by high-intensity guiding ruler and numerical control that cylinder drives.In axle head and shaft shoulder location, the data length information that while grating chi obtains calculates and respectively requires the length measured size through guiding ruler.
The axletree conveying and positioning device: axletree rolls on the nylon guide rail, and the nylon guide rail is installed on the platform.Stir the axletree reach by the dial of air cylinder driven one propulsive mechanism, while dial when axletree entering detecting position is meets the wheel state, makes axletree get into the measuring position stably.
When beginning to detect. operating personnel place axletree on the transport, and this device can be transported to the detection station by part with axle to be detected according to the instruction of industrial computer. and transport sector work is soft, and coordination is to guarantee producing collision each other between workpiece; Detent mechanism can be implemented accurately location by preset requirement to workpiece.
The axletree rotating mechanism: the axletree rotating mechanism adopts step motor drive, and the precision that can guarantee to rotate is in ± 5 °.
Calibration system: equipment has standard and demarcates ring gauge.Demarcating ring gauge by the measurement unit calibrating through constitutional law devise a stratagem amount qualification, is the benchmark of device measuring; System is fixed to its rower automatically when each the measurement, to satisfy measurement requirement.
Top location structure:, guaranteed the accurate location of every axletree through top location structure.
In measuring system, in order to satisfy requirements such as throughput rate and accuracy of measurement, used a pair of high precision and large measuring range magnetic grid horizontal metroscope, standard axletree and tested vechicle shaft diameter are carried out contact is differential to compare and measure; Used the straight line locating platform to carry out the automatic axial location; Automatic location, lifting, rotation driving, the ejecting mechanism of wheel shaft have been adopted.The characteristics of the maximum of this cover measuring system are: the reliable measurement of diameter, accurate and stable.
Embodiment recited above describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Design under the spiritual prerequisite not breaking away from the utility model; Various distortion and improvement that the common engineering technical personnel in this area make the utility model technical scheme all should fall in the protection domain that claims of the utility model confirm.
