Description
Technical Field
[0001] The utility model belongs to the technical field of gear hardness detection, and in particular relates to a master and slave gear hardness detection platform. Background Art
[0002] With the development of industrial automation and mechanical manufacturing technology, master and slave gears are increasingly used in various mechanical equipment. The hardness of gears directly affects their service life and transmission efficiency, so it is very necessary to accurately detect the hardness of gears. Existing master and slave gear hardness testing stations usually adopt a fixed installation method, which is not stable enough for the fixation of gears. It is easy to cause the gears to loosen during the hardness test, affecting the test accuracy. When testing gears, the existing master and slave gear hardness testing stations often have the problem of gears being easy to loosen during the lateral hardness test of gear teeth due to unstable fixation. This will lead to inaccurate test results, affect the quality and performance of the gears, and may even cause damage to the gears. In addition, this instability will also affect the test efficiency, extend the test time, and reduce production efficiency. Utility Model Content

After feeding, the outer end of the feed lifting rod is set against the inner side of the hole of the test gear, and is fixed to the gear mounting column by means of an anti-slip gasket, a locking nut and the test gear. Then, the oil cylinder drives the feed lifting rod to rise, pushes the beveled locking pin to move outward and presses the inner side of the hole of the test gear, thereby realizing the enhanced fixing and clamping function of the test gear.
[0011] Preferably, a return spring is arranged on the periphery of the inner end of the bevel locking pin, and one end of the return spring is fixedly connected to the outer side of the bevel locking pin.
