Abstract
The invention relates to a height detecting device, which comprises a vertical moving mechanism, wherein a cantilever beam extends out of the vertical moving mechanism; a support is arranged on the cantilever beam; a first linear bearing and a second linear bearing are respectively arranged at two ends in the support; an outer guide post is arranged in the first linear bearing and the second linear bearing; a third linear bearing and a fourth linear bearing are respectively arranged at two ends in the outer guide post; an inner guide post is arranged in the third linear bearing and the fourth linear bearing; a sensor fixing seat is arranged on the outer side of the top of the outer guide post; a turning stop block is arranged in the sensor fixing seat; a displacement sensor is arranged on the sensor fixing seat; a reference block is arranged on the outer side of the bottom of the outer guide post; and a measuring post is arranged at the front end of the inner guide post. By adopting the structure, the height can be accurately detected by one displacement sensor rather than two displacement sensors; and the device is simple in structure and reduces measurement errors, and a program for controlling the displacement sensor is simple.
Description
Technical field
The present invention relates to a kind of checkout equipment in the machine industry, especially relate to a kind of height detecting device.
Background technology
At present, the accuracy requirement of the product of in mechanical industry, producing is increasingly high, so also need increasingly high in the height detection precision; Existing height detecting device needs 2 displacement transducers measuring basis faces and to be detected respectively, and cost of manufacture is higher, in programmed control, will calculate the difference of 2 readings; And its programming is comparatively complicated; When the space between the detected material was narrower and small, mechanism was difficult to arrange wherein, is inconvenient to operate.
Summary of the invention
Technical matters to be solved by this invention provides a kind of simple in structure and only need the height detecting device of a displacement transducer.
The present invention solves the technical scheme that its technical matters takes: a kind of height detecting device, comprise up-down mechanism, and stretch out a semi-girder on the up-down mechanism; Described semi-girder is provided with bearing; Two ends in the inside of bearing are respectively equipped with first linear bearing and second linear bearing, are provided with outer guiding post in the inside of first linear bearing and second linear bearing, and the two ends inner at outer guiding post are respectively equipped with the 3rd linear bearing and the 4th linear bearing; Inside at the 3rd linear bearing and the 4th linear bearing is provided with inner guiding post; Be provided with the sensor holder in the outside on outer guiding post top, the inside of sensor holder is provided with the spline piece, on the sensor holder, is provided with displacement transducer; The outside in the bottom of outer guiding post is provided with reference block, is provided with measurement column at the front end of inner guiding post.
Further concrete, described up-down mechanism comprises the drive block that is fixedly connected with semi-girder, and drive block is connected with the driving cylinder, drives cylinder and is fixed on the driving cylinder mount pad, drives the cylinder mount pad and is installed on the guide pillar.
The invention has the beneficial effects as follows: adopted after the said structure, need not use two displacement transducers, only just can detect height accurately with 1 displacement transducer; And it is simple in structure; Reduce measuring error, the program of control bit displacement sensor is comparatively simple, the convenient use.
