Specific embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with attached drawing.It should be understood that herein
Described specific embodiment is only used for describing and explaining the present invention, and is not intended to limit the utility model.
Structure referring to fig. 1 and fig. 2, can be by workpiece off-line measurement device provided by the utility model to various
The workpiece to be measured of type and structure carries out off-line measurement.As shown in the figure, which includes rack 1, surveys
Amount station pallet 5 and measuring station 6, wherein be provided with driving cylinder 2 in rack 1, positioned at measurement position be used to that workpiece to be measured to be arranged
Tray for work pieces 3 and positioned at zero check for the calibration component pallet 4 of calibration component to be arranged；Measuring station pallet 5 is rotatably arranged
Can be converted between measurement position and zero check in rack 1, and it connect with driving cylinder 2 with can be in the drive of driving cylinder 2
Lower lifting；Measuring station 6 includes measurement sensor, and measuring station 6 is arranged on measuring station pallet 5.
In the technical scheme, due to being provided with tray for work pieces 3 in rack 1, when needing to measure, measuring station 6 with
Measuring station pallet 5 be in zero check, then by workpiece to be measured place such as carry or by hoisting mechanism handling arrive this
On tray for work pieces 3, then, measuring station 6 is passed as measuring station pallet 5 turns to measurement position and drops to measurement by driving cylinder driving
The measuring surface of sensor contact measured amount workpiece measures, and the change information of the transmitting of measurement sensor such as displacement variable
Or reading variable quantity then may indicate that whether the measuring surface of workpiece to be measured meets necessary requirement, in addition, being directed to different structure
Or the workpiece to be measured of size, it can easily replace corresponding measuring station 6 or replace the corresponding measurement sensing of measuring station 6
Device, and after being measured, measuring station 6 can be moved to zero check and pass through the calibration component school zero on calibration component pallet 4, with
Convenient for measurement next time, therefore can be while promoting the convenience and stability of measurement, workpiece off-line measurement device operation
More convenient, cost is smaller, and cost performance is higher.
Certainly, in workpiece setting to be measured when on tray for work pieces 3, in order to promote the accuracy of measurement, workpiece to be measured
It can be limited by corresponding location structure, for example, workpiece off-line measurement device includes the workpiece positioning that measurement position is arranged in
Structure, the workpiece positioning structure can be set on tray for work pieces 3, perhaps can be set in rack 1 or are arranged in simultaneously
On tray for work pieces 3 and rack 1, it is to be understood that, no matter how workpiece positioning structure is arranged, as long as can be to setting in workpiece support
Workpiece to be measured on disk 3 is limited, its movement is placed；Meanwhile in order to make full use of the workpiece positioning structure, surveying
Amount station pallet 5 is pre-positioned when turning to measurement position by workpiece positioning structure, it is, the workpiece positioning structure can also be to place
Measuring station pallet 5 in measurement position is pre-positioned.In this way, the workpiece positioning structure can be simultaneously to workpiece to be measured and measurement
Pallet 5 of standing is limited, to improve the utilization rate of structure, avoid using additional position limiting structure to measuring station pallet 5 into
Row limit, this is just able to ascend the convenience and stability of measurement, while making the cost of the workpiece off-line measurement device smaller,
