The utility model content
In order to overcome the deficiencies in the prior art, the utility model is to provide a kind of can effectively guarantee product quality, and the hard disk drive of high efficiency goes out pin mechanism with rotating shaft.
The utility model is achieved through the following technical solutions:
A kind of hard disk drive goes out pin mechanism with the assembling rotating shaft, comprise the product base plate, be arranged on the isometry block of product base plate bottom, be arranged on the substrate of isometry block bottom, what be arranged on the substrate bottom goes out the pin cylinder, going out pin cylinder top is connected with towards pin, towards pin extend into the middle part of substrate and isometry block that be provided with die cavity its form fit in, pin is arranged on the top towards pin, and also be provided with towards the pin fixed block in the outside towards pin, it is characterized in that: be fixedly connected on out on the pin cylinder towards the pin fixed block, and at the die cavity of substrate inside and towards also being provided with a guiding linear bearing between the pin, and also be provided with one towards pin height adjusting screw in bottom towards pin, this towards the pin adjusting screw be more renew at every turn dash pin the time be used for fine setting, adjust height at every turn after this height towards pin do not need to adjust again.
Above-mentioned hard disk drive goes out pin mechanism with the assembling rotating shaft, it is characterized in that, also is provided with towards the pin holding screw in the left and right sides towards the pin fixed block, described end towards the pin holding screw with contact towards pin.
The beneficial effects of the utility model are: the utility model is by carrying out fastening towards the pin holding screw to the pin that dashes after regulating height through overshoot pin height adjusting screw, the pin of adjusting can accurately move up and down in the guiding linear bearing, improved the stability that the pin position greatly, guaranteed the quality of product, improved the serviceable life of pin, and also improved production efficiency simultaneously, in addition, when changing pin, only contour the unclamping simultaneously towards the pin holding screw soon that need remove on the substrate gets final product, maintenance and replacing are all very convenient, have avoided the problem of other parts that match on the easy damaged substrate when the dismounting substrate to take place, and have reduced the requirement of production technology.
