Embodiment Construction
[0055] The technical solutions of the present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.
[0056] See figure 1 and figure 2 as shown, figure 1 It is a schematic diagram of the overall structure of the automatic screw detection equipment of the present application, figure 2 for this application figure 1 internal schematic. The automatic screw detection equipment of the present application includes a loading station A, a testing station B, a blanking station C and a control system (PLC). The loading station A is used for fast feeding; the detection station B is used to complete the data detection of the screw D; the unloading station C is used to classify the screws neatly; The control system PLC is used to receive, analyze and control the operation of the equipment on each of the stations. The feeding station A and the detection station B are covered in the soundproof cover 1 to reduc...

The invention discloses a screw straightness detection mechanism and an automatic screw detection device. The screw straightness detection mechanism is characterized in that the mechanism comprises a finger cylinder clamp, a pressing shaft and a straightness checking fixture, the finger cylinder clamp is fixed on a lower clamp mounting plate, the lower clamp mounting plate is connected with an upper clamp mounting plate through a connecting rail and is driven by a cylinder to move back and forth relative to the upper clamp mounting plate, the upper clamp mounting plate is driven by a driving mechanism to move up and down, the pressing shaft penetrates through a spring and then is mounted on a pressing shaft connecting plate through a linear bearing, the pressing shaft connecting plate is fixed above a detection position through a pressing shaft mounting plate, the upper end of the pressing shaft penetrates through the pressing shaft connecting plate, a contact plate and a locking gasket are mounted at the upper end part of the pressing shaft, a contact sensor is arranged on the contact plate, the straightness checking fixture is connected to a rail of a jacking rail plate through a sliding block, the straightness checking fixture is aligned to the central axis where the pressing shaft is located, and the sliding block is in driving connection with a testing fixture and drives the straightness checking fixture to linearly slide up and down through the testing fixture.
Description
technical field [0001] The invention relates to the mechanical field, more specifically, a screw straightness detection mechanism and a screw automatic detection device equipped with the screw straightness detection mechanism. Background technique [0002] The factory of the screw needs to carry out various precision compliance tests. At present, the detection of screws is carried out manually using professional tools. Especially when testing the straightness of screws, a standard ruler is used for side-by-side measurement. This kind of manual measurement will have some inevitable deviations due to the subjective consciousness of the inspector or operating specifications, and the detection is inaccurate and inefficient. In the face of large quantities of products, the current method of manual sampling is used to complete the inspection. However, this type of sampling method cannot ensure that the quality of all products is up to standard, and the work efficiency is low an...
