Automatic workpiece opening detection device

Abstract

The invention discloses an automatic workpiece opening detection device. A detection platform is provided with a plurality of detection mechanisms at intervals, a sliding seat fixing block is fixedly mounted on a rack, a detection sliding seat is mounted on the sliding seat fixing block in an up-down sliding manner, a sliding seat driving mechanism is in transmission connection with the detection sliding seat, and two detection firing pins are arranged at intervals in the length direction of a workpiece. The two detection firing pins are installed on the detection sliding seat in an up-down sliding mode, two sensing elements are fixedly installed on the two sides of the upper portion of the detection sliding seat respectively, and the two sensing elements are matched with the two corresponding detection firing pins in a sensing mode respectively. The diameters of the two detection probes on the same detection mechanism are the maximum value and the minimum value of a workpiece opening respectively, and the sensing element senses whether the detection probes can be inserted into the workpiece opening or not, so that whether errors meet standards or not is judged, the detection method is simple, the detection accuracy is high, the structure is simple, and the cost is low. Theplurality of detection mechanisms are arranged on the rack at intervals, manual one-by-one measurement is not needed, and each detection point of the workpiece opening can be measured at a time.

Description

technical field [0001] The invention relates to the technical field of opening detection devices, in particular to an automatic detection device for workpiece openings. Background technique [0002] In daily life, many product manufacturing and building materials need to use workpieces with openings. Before the workpieces are delivered or enter the next processing link, their opening dimensions need to be inspected to ensure that the opening dimensions are within the normal and reasonable tolerance range. Traditional inspection methods It is manually measured by measuring instruments, such as vernier calipers. When using vernier calipers to measure, it is necessary to manually read the measuring instruments, and the force used in the measurement, the angle and depth of the calipers have a certain degree of measurement error, and the detection accuracy is not high. , is not convincing; for openings with long workpiece lengths, it is necessary to measure the openings at interv...

[0002] In daily life, many product manufacturing and building materials need to use workpieces with openings. Before the workpieces are delivered or enter the next processing link, their opening dimensions need to be inspected to ensure that the opening dimensions are within the normal and reasonable tolerance range. Traditional inspection methods It is manually measured by measuring instruments, such as vernier calipers. When using vernier calipers to measure, it is necessary to manually read the measuring instruments, and the force used in the measurement, the angle and depth of the calipers have a certain degree of measurement error, and the detection accuracy is not high. , is not convincing; for openings with long workpiece lengths, it is necessary to measure the openings at intervals and record the values ​​of each measurement point. The measurement efficiency is low, and it is easy to make mistakes in the process of repeated recording and reading, resulting in detection The accuracy is reduced; there is also a special measuring tool matched with the opening size, and the special measuring tool that inserts the maximum error value and the minimum error value is used to determine whether the opening size is within the error range. Although this method does not require readings, it still needs to be done manually. The measurement and detection efficiency is still not high. For the opening with a long workpiece length, the manual labor is labor-intensive, time-consuming and labor-intensive, and cannot meet the requirements of mass inspection; in addition to the traditional manual measurement, there are also equipment for automatically detecting the opening size, which is bulky , the structure is complex and the cost is high, so it is necessary to improve
