A counting device for fatigue testing of router connector threads

Abstract

The invention discloses a counting device for testing the fatigue strength of router joint threads. The counting device comprises a device body. A rotating shaft driven by a rotary power device to rotate forwardly and reversely is rotationally arranged on the device body. The rotating shaft is provided with a threaded sleeve matched with a joint. A base is arranged on the device body. A mounting piece is horizontally arranged on the base in the axial direction of the threaded sleeve in the sliding manner. A router joint is detachably arranged on the mounting piece. The threaded section of the router joint is matched with the threaded sleeve. A linear traction device for driving the mounting piece to horizontally slide is arranged between the mounting piece and the base. A detecting and counting mechanism for detecting the linear reciprocating operation of the router joint is arranged on the device body. By means of the counting device, the threaded sleeve can be automatically screwed onto the threaded section of the router joint and can also be automatically unscrewed from the threaded section of the router joint, and the automatic counting function is realized at the same time. Meanwhile, the counting accuracy and the counting efficiency are greatly improved.

Description

technical field [0001] The invention relates to a counting device, in particular to a counting device for thread fatigue testing of router connectors. Background technique [0002] The router connector needs to perform a fatigue test on the threaded section. The main operation is to screw in and out a certain number of times between the threaded section and the screw sleeve by rotating the router connector. During the screwing in and out process, the thread section will be damaged. Plating, and then put the router connector into the salt spray test machine for salt spray test, so as to realize the thread fatigue test of the router connector. However, the current method is mainly to manually screw the screw sleeve into the threaded section of the router connector, and the times of screwing are all counted by the operator himself. There are following differences in this way: 1. The manual counting is not accurate, and the operation Workers may not count enough or exceed the s...

However, the current method is mainly to manually screw the screw sleeve into the threaded section of the router connector, and the times of screwing are all counted by the operator himself. There are following differences in this way: 1. The manual counting is not accurate, and the operation Workers may not count enough or exceed the specified number of times due to external factors, which will cause the follow-up salt spray test results to be inaccurate; 2. Manual operation is heavy and inefficient; 3. Manually screwing in the screw sleeve may not be screwed in place. The coating on the threaded section is only partially damaged, so the test results are still inaccurate
