Abstract
The utility model discloses a detecting and fixing device of a central hole of a hard disk negative, including a workbench, a clamp seat for fixing a clamp, a motor and a motor controller. The clamp seat is arranged on the workbench by a rotating shaft at the bottom thereof; and the rotating shaft is connected with the output shaft of the motor by a transmission mechanism. The utility model does not need special operator to revolve products, thus saving manpower by 100 percent. The utility model can work continuously, therefore time is saved and work efficiency is improved to a certain degree. Because the motor is used to drive the rotating shaft to revolve, the rotating speed of products is easy to control and is more stable and more even relative to manual rotating speed. Because the rotating speed of products is stable, the detection of products is more accurate, consequently the quality of products is improved.
Description
Technical field
The utility model relates to a kind of hard disk plate center hole test fixture.
Background technology
The Spindle Motor that the hard disk egative film is mainly used to install and protect hard disk magnetic disc (2.5 inches or 3.5 inches) and drives the magnetic disc rotation; in the concrete assembling production run of hard disk; the aperture size measurement that is used for installing the center pit of Spindle Motor on the hard disk egative film is quite crucial; it is directly connected to the accuracy of Spindle Motor location, so need 100% detect.Detection method commonly used at present is to adopt air gauge that the size of center pit is measured and verify error, in this course, therefore the arbitrfary point in air gauge inspection center hole needs corresponding rotation hard disk egative film 360 degree, i.e. a week, cooperate the measurement of air gauge.Because the stationary installation of existing auxiliary clamping hard disk egative film does not possess the function of automatic rotation, therefore need operate this complete equipment separately by an employee does detection, in the testing process, rotate product 360 degree by this employee, change product and continue to detect Deng detecting the back that finishes, not only time-consuming but also require great effort, and often rotate the inhomogeneous decline that also can cause measuring accuracy, greatly reduce work efficiency.
Summary of the invention
The utility model purpose is: provide a kind of and can drive the hard disk egative film rotation of fixing on it automatically, make things convenient for center pit to detect, be beneficial to the hard disk plate center hole test fixture of increasing work efficiency.
The technical solution of the utility model is: a kind of hard disk plate center hole test fixture, comprise worktable and the clamp base that is used for fixing anchor clamps, it also comprises motor and electric machine controller, clamp base is articulated on the worktable by the rotating shaft of its bottom, and rotating shaft is connected on the output shaft of motor by gear train.
Gear train described in the utility model is any one form in belt, chain or the gear; Motor further is fixed on the worktable described in the utility model simultaneously, keeps compact overall structure, is convenient to move simultaneously in company with worktable.The utility model is when work, with product also is that the hard disk egative film is installed in the anchor clamps be clamped on the clamp base, starter motor, and rotate by the driven by motor rotating shaft, thereby make the hard disk egative film to rotate automatically, convenient air gauge at hard disk plate center hole dimension detects and carries out smoothly.
In rotating shaft, further be equipped with near the inductive switch sensor in the utility model, be electrically connected with electric machine controller near the inductive switch sensor.Effect near the inductive switch sensor mainly is: when the air gauge checkout equipment finishes to the hard disk plate center hole dimension detection that is fixed in the anchor clamps, also be that the driven by motor rotating shaft is revolved three-sixth turn and finished, pass to checkout equipment and electric machine controller near the inductive switch sensor with end signal this moment; Output is measurement result the time on the checkout equipment, and the output shaft that is stopped motor by electric machine controller rotates, and waits for the taking-up of hard disk egative film and packs another not after testing hard disk egative film into.Certainly as for being prior art, no longer stating near the concrete form of inductive switch sensor and with the control mode that is electrically connected between electric machine controller more.
The utility model advantage is:
The utility model needs the workman manually to rotate the stationary installation that product realizes that center pit detects to have following positive effect than traditional:
1. the utility model does not need special operator to rotate product, has saved manpower 100% and because can continual continuous firing, have saved the time, has improved work efficiency to a certain extent.
2. the utility model is owing to adopt motor to drive the rotating shaft rotation, so the rotational speed of its product is easy to control, and the manual rotational speed of counterpart is also more steady, more even.Because product rotating speed when rotated is reliable, therefore just more accurate to the detection of product, also just improved the quality of product.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is a front view of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
Wherein: 1, worktable; 2, anchor clamps; 3, clamp base; 4, motor; 5, rotating shaft; 6, gear train; 7, output shaft; 8, near the inductive switch sensor; 9, hard disk egative film.
Embodiment
Embodiment: be a kind of embodiment of the utility model hard disk plate center hole test fixture in conjunction with Fig. 1 and Fig. 2 are described: it comprises worktable 1, is used for fixing the clamp base 3 of anchor clamps 2, motor 4 and electric machine controller; The bottom of clamp base 3 is fixed with rotating shaft 5, and clamp base 3 is articulated on the worktable 1 by this rotating shaft 5, and rotating shaft 5 is connected by gear train 6 on the output shaft 7 of motor 4, and motor 4 is fixed on the worktable 1.Also be equipped with near inductive switch sensor 8 in the described rotating shaft 5, be electrically connected with electric machine controller near inductive switch sensor 8.
The utility model is when work, with product also is that hard disk egative film 9 is installed in the anchor clamps 2 that are clamped on the clamp base 3, starter motor 4, and by motor 4 drive rotating shafts 5 rotations, thereby make hard disk egative film 9 to rotate automatically, convenient air gauge at hard disk egative film 9 central hole size detects and carries out smoothly.Finish when the air gauge checkout equipment detects the central hole size that is fixed on the hard disk egative film 9 in the anchor clamps 2, also be that motor 4 drives rotating shafts 5 and revolves three-sixth turn and finish, and pass to checkout equipment and electric machine controller near inductive switch sensor 8 with end signal this moment; Output is measurement result the time on the checkout equipment, and the output shaft 7 that is stopped motor 4 by electric machine controller rotates, and waits for the taking-up of hard disk egative film 9 and packs another not after testing hard disk egative film into.
Present embodiment needs the workman manually to rotate the stationary installation that product realizes that center pit detects to have following positive effect than traditional:
1. it does not need special operator to rotate product, has saved manpower 100%; And because can continual continuous firing, saved the time, improved work efficiency to a certain extent.
2. it is owing to adopt motor 4 to drive rotating shaft 5 rotations, so the rotational speed of its product is easy to control, and the manual rotational speed of counterpart is also more steady, more even.Because product rotating speed when rotated is reliable, therefore just more accurate to the detection of product, also just improved the quality of product.
