Description

Technical Field

[0001] This utility model relates to the field of calibration technology, and more specifically, to a thread testing and calibration device. Background Technology

[0002] In industrial production, screw threads serve as the link connecting industrial components, and their quality directly affects the stability and reliability of parts, products, and production lines. When multiple screw threads are required to connect industrial products or parts, the thread holes of the parts should be inspected for openness, depth, and other aspects before assembly to avoid situations where screws cannot be screwed in or are not screwed in properly. In practice, the measurement of screw thread quality often relies on manual labor, which is not only inefficient but also difficult to control in terms of accuracy.

[0003] The thread detection device disclosed in application number CN202221992732.X is also an increasingly mature technology. It involves raising and retracting an electromagnetic limiting component, placing a bolt in a slot, and then fixing the bolt using the electromagnetic limiting component. A sliding fixing plate then moves the detection plate, simultaneously causing a bottom sliding rod to slide along a groove. This sliding rod compresses a spring. When the bolt is inserted into the thread groove on the side of the detection plate, the sliding of the fixing plate stops. Turning the handle then rotates the shaft. Due to the presence of a first and second bearing, the shaft rotates... This method results in a smoother operation. The rotation of the shaft causes the bolt to rotate and insert into the threaded groove. The bolt is then detected by a sensor inside the threaded groove. Once the detection is complete, the shaft can be rotated in the opposite direction, causing the bolt to rotate out of the threaded groove. At the same time, the compressive force on the spring is released, so the spring will reverse and drive the slide bar back to its initial state. The slide bar, through the fixing plate, will drive the detection plate back to its initial state. Then, by controlling the retraction of the electromagnetic limiter, the bolt can be removed from the placement slot, completing the detection. This method allows for convenient placement of bolts inside the thread detection device, simplifying the process and preventing damage to the thread detection device from the bolts, thus facilitating user operation.

[0004] Based on this, we agree with the advantages of the aforementioned products, but the following drawbacks still exist: While the operation of this type of detection device is relatively simple in practical use, it is not automated enough and requires multiple manual adjustments, which increases the workload of staff.
