Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-3, the technical solution adopted by the present invention is that the height detection mechanism comprises a frame 1, a positioning slide plate 2 sliding along the frame 1, and a feedback slide plate 3 sliding along the positioning slide plate 2, wherein the sliding directions of the positioning slide plate 2 and the feedback slide plate 3 are the same; the tail end of the positioning sliding plate 2 is fixedly provided with a positioning sleeve 21; a positioning rod 31 is fixedly installed at the tail end of the feedback sliding plate 3, and the positioning rod 31 is sleeved in the positioning sleeve 21 and protrudes out of the tail end of the positioning sleeve 21; at least two groups of photoelectric sensors 22 are arranged on the positioning sliding plate 2; the feedback sliding plate 3 is provided with at least two induction sheets 32; the two sets of photosensors 22 are respectively positioned to correspond to the corresponding sensing tabs 32. In this embodiment, the positioning slide plate 2 and the feedback slide plate 3 slide along the vertical direction; the front end is a top end, and the tail end is a bottom end; such orientation arrangement facilitates detection.
Further, when the end of the positioning rod 31 coincides with the end of the positioning sleeve 21, one set of the photosensors 22 is located to coincide with the corresponding sensing sheet 32, and the other set of the photosensors 22 is located not to coincide with the corresponding sensing sheet 32.
The technical scheme is that a limit baffle is arranged at the front end of the positioning sliding plate, and a return spring 4 is arranged between the limit baffle and the front end of the feedback sliding plate. And the device also comprises a power mechanism (not numbered) for driving the positioning sliding plate 2 to move.
The utility model discloses a height detection mechanism passes through locating lever and abutment sleeve's cooperation, detects the difference in height of work piece that awaits measuring to the conversion realizes different bright lamp states to two sets of response thin slices, photoelectric sensor cooperation, shows the difference in height situation directly perceivedly.
The working process is as follows: (1) The power mechanism pushes the positioning sliding plate 2 to move downwards, and the positioning rod 31 protrudes out of the positioning sleeve 21, so that the positioning rod 31 firstly contacts a magnet embedded in the plastic rod, and the positioning rod 31 and the feedback sliding plate 3 connected with the positioning rod stop moving downwards;
(2) The positioning slide 2 continues to move downwards and compress the return spring 4 until the lower surface of the positioning sleeve 21 contacts the upper surface of the plastic rod and stops. At this time, the distance between the lower surface (magnet contact surface) of the positioning rod 31 and the lower surface (plastic rod contact surface) of the positioning sleeve 21 is the height difference between the upper surface of the magnet and the upper surface of the plastic rod. The method for measuring the height difference between the two surfaces of the product can avoid the size error of mechanical parts, the size error of different products and the like.
(3) If the upper surface of the magnet is flush with the upper surface of the plastic rod, the lower surfaces of the positioning rods 31 and the positioning sleeves 21 are overlapped, the position of one group of the photoelectric sensors 22 is overlapped with the corresponding induction sheet 32, the position of the other group of the photoelectric sensors 22 is not overlapped with the corresponding induction sheet 32, and only the overlapped group of the two groups of the photoelectric sensors 22 is lighted. If the upper surface of the magnet is higher than the upper surface of the plastic rod, the other group of the lamps are lighted. If the upper surface of the magnet is lower than the upper surface of the plastic rod, the two groups of lamps are not lighted. The detection precision can reach +/-0.1 mm.
The above is only the preferred embodiment of the present invention, the present invention is not limited to the above embodiment, and various modifications or variations of the present invention do not depart from the spirit and scope of the present invention in the implementation process, and belong to the claims and the technical scope equivalent of the present invention, then the present invention is also intended to include these modifications and variations.
