The utility model discloses it is not enough to solve prior art and research and propose.
[ Utility model ] content
The utility model aims at overcoming the shortcoming of above-mentioned prior art, provide a magnetic head testing arrangement.
The utility model discloses can realize through following technical scheme:
the utility model discloses a magnetic head testing arrangement, including bottom plate and magnetic head, bottom plate top symmetry is fixed with two fixed plates, two be fixed with driving shaft and driven shaft between the fixed plate respectively, the driving shaft passes through hold-in range and driven shaft wraparound, driving shaft and test motor's output fixed connection, the bottom plate top still is fixed with the roof, be fixed with elevator motor on the roof, the elevator motor output is fixed with the lead screw, the roof below still is equipped with the mounting panel, be fixed with screwed pipe and slide bar on the mounting panel, the slide bar pass aforementioned roof and with roof sliding connection, the lead screw end stretch into inside and with screwed pipe threaded connection of screwed pipe, the magnetic head is fixed in the mounting panel bottom. The magnetic head is fixed at the bottom of the mounting plate, the screw rod is driven to rotate by the lifting motor, when the screw rod rotates, the magnetic head moves downwards and rubs with a synchronous belt driven to rotate by the testing motor, after a period of time, the lifting motor drives the screw rod to rotate reversely, the magnetic head rises and is separated from the synchronous belt, the operation is circulated, after a period of time, the magnetic head is taken down to confirm the abrasion condition, the magnetic head and the synchronous belt are contacted once for a card inserting period, the number of times of contact between the magnetic head and the synchronous belt can be confirmed by testing time, the service life of the magnetic head can be effectively confirmed by combining the abrasion condition of the magnetic head, and through machine testing, the condition consistency of each testing can be effectively guaranteed, the accuracy of the testing.
Preferably, a fixed pipe is fixed on the mounting plate, and the magnetic head is fixedly connected with the fixed pipe through a screw.
Compared with the prior art, the utility model has the advantages that:
the number of times of contact between the magnetic head and the synchronous belt can be confirmed through the test time, so that the friction number of the magnetic head is confirmed, the service life of the magnetic head can be effectively confirmed by combining the abrasion condition of the magnetic head, the consistency of the test conditions at each time can be effectively guaranteed through machine test, the test accuracy is guaranteed, and the test speed is high.
