Workpiece height detection device

Abstract

The invention discloses a height detection device for workpieces. The lower end of a motor (15) is fixedly connected to a support (1), the upper end is connected to the bottom of a turntable (17) through a transmission mechanism, and the turntable (17) is connected to the support mechanism through a support mechanism. The support (1) is rotatably connected; the lower end of the central support shaft (6) is fixedly connected to the support (1), the middle part is sleeved in the turntable (17), and the upper end is connected to one end of the pushing and blanking assembly; the workpiece fixing seat The number is multiple, and they are evenly distributed along the edge of the turntable (17) and are movably connected with the turntable (17). The detected workpiece (7) is placed vertically in the workpiece fixing seat; One end is fixedly connected with the support (1), and the other end faces the top of the workpiece (7). After adopting the above structure, the work efficiency of detection and sorting is greatly improved, and the work of detection and sorting is also made more stable, and the phenomenon of wrong detection and wrong selection is avoided.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a height detection device suitable for workpieces in assembly line production. Background technique [0002] With the increasing requirements for product quality, the precision requirements for the product size of parts are also getting higher and higher. For example, shaft products not only have requirements for their radial dimensions, but also require the accuracy of their length dimensions to be less than 0.01mm. Products need to be inspected before they are put into storage. Usually, for small batches of shaft products, this inspection is done manually using vernier calipers or micrometers. Therefore, this inspection is extremely inefficient and subjective. The impact is relatively large, so the products put into storage may not fully meet the storage standards. For large quantities of shaft products, the inspection before warehousing is usually carried out through the...

Problems solved by technology

[0004] However, the above-mentioned device involves electronic components such as controllers and photoelectric detectors, and all functional parts are implemented by the controller. Therefore, on the one hand, due to the short service life of the electronic components, the detection and sorting The device will be maintained frequently or inspected regularly; on the other hand, electronic components are more easily affected by the outside world, which affects their normal performance, and may cause inaccurate detection. Therefore, the stability of the detection results is poor
