Patent Office of the People's Republic of China discloses a kind of measured material of hard disk driving frame, it is to be made of a worktable and portal frame, on described worktable, be provided with the bogie support column that is used to place bogie, be used to lock bogie directly over being arranged on the bogie support column by portal frame again.Said structure, though the resonance characteristics of test products preferably, the setting of portal frame makes clamp structure huge, complexity, the part of processing and assembling is many, thereby has higher processing cost.
The utility model content
The purpose of this utility model is to overcome the prior art defective, provides a kind of simple in structure, and processing cost is low, exactly the measured material of the hard disk driving frame of the resonance characteristics of test products.
The utility model is to realize like this, a kind of measured material of hard disk driving frame, comprise a worktable, described worktable is provided with the bogie support column that is used to place bogie, described bogie support column surrounding is provided with magnet support column and positioning component, on described bogie support column, but also be provided with the locked component of fixed drive frame.
Preferably, described locked component is for placing locknut and the pad on the described bogie support column.
Further, in the utility model structure, also offer groove on the described worktable downwards, be provided with cable sheet reference column in the described groove.
Further, in the utility model structure, also be provided with the bogie reference column on described worktable, it is positioned at described bogie support column surrounding.
Further, in the utility model structure, offer a chute on the described worktable, described positioning component comprises a slide block that can move, is located at above the described slide block and the slider nut that slide block can be locked in described chute, also comprise the column of being located at described slide block one side, cover inserts in the branch head position sheet on the described column, and is located at the described minute lid on the head position sheet.
The utility model is simple in structure, compact, hard disk driving frame does not need by huge portal frame location, directly adopt locknut and spacers to get final product, can shorten installation time greatly, cut down finished cost, save rapidoprint, also can improve the rigidity of anchor clamps measurement and the stability/repeatability of use, test result is more clear.Also need use cushion rubber owing in the portal frame in the prior art, and cushion rubber belongs to wear-resistant, will change about half a year, therefore, the utility model also can reduce maintenance cost.
Description of drawings
Fig. 1 is the utility model example structure synoptic diagram.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Referring to Fig. 1, the utility model embodiment comprises a worktable 1, described worktable 1 is provided with a bogie support column 11, this bogie support column 11 generally is positioned at the center of worktable 1 table top, be used to place bogie, around described bogie support column 11, be provided with magnet support column 12 and positioning component 2, described magnet support column 12 generally can be provided with about three, to support magnet better.Bogie support column 11 exceeds setting value than magnet support column 12, this setting value is provided with different setting values according to different products, making to be positioned over magnet and bogie on the two to have certain height poor, is 0.5-1.0mm with the difference in height between assurance magnet and the bogie drive coil.This height dimension is analog-driven frame employed height dimension in the actual use of hard disk, can change to some extent according to this height dimension of different product, simultaneously guaranteed that also pumping signal is consistent with the hard disk duty, so that the resonance characteristics of test products more accurately.On described bogie support column 11, but also be provided with the locked component 2 of fixed drive frame.
In the concrete structure design, described locked component 2 is for placing locknut 21 and the pad 22 on the described bogie support column 11.Described pad 22 adopts engineering plastics (POM) manufacturing, avoids product to be damaged in the locking process.
In the utility model specific embodiment, also be provided with bogie reference column 13 around the bogie support column 11, bogie reference column 13 is used to locate the position of bogie, to guarantee that different survey crews is in different measuring processes, the position of bogie is consistent, with the accuracy of raising measurement result and the repeatability of measuring process.
Please again referring to Fig. 1, in the utility model, bogie also can attach in some cases and be connected with the cable sheet and/or divide magnetic head, when bogie also is connected with the cable sheet or divides magnetic head, corresponding align member need be set on worktable 1.In the utility model, when bogie also was connected with the cable sheet, described worktable 1 also offered groove 14 downwards, and it is other to be positioned at bogie support column 11, is provided with cable sheet reference column 15 in the described groove 14, in order to the cable sheet is positioned.
When bogie also is connected with the branch magnetic head, in the utility model embodiment, around bogie support column 11, also be provided with branch head position assembly 3, comprise a slide block 36 in described minute head position assembly 3, described slide block 36 places in the chute 17 that correspondence is offered on the described worktable 1, can in described chute 17, move, also being provided with on described slide block 36 can be with the slider nut 35 of slide block 36 lockings, simultaneously, side at described slide block 36, also be provided with a column 32, cover is inserted with branch head position sheet 34 on the described column 32, and head position sheet 34 was provided with lid 33 in described minute, vertical in described minute head position sheet 34, also be provided with register pin 31, be used for the installing and locating of branch magnetic head.
In the design of the utility model concrete structure, worktable 1 is provided with the table top of bogie support column 11 and opposing face is the plane, and worktable 100 upper sides are provided with projection 16.Preferred embodiment, flatness is less than 0.005mm, and the depth of parallelism on this two plane is less than 0.008mm.The requirement of the flatness and the depth of parallelism is to guarantee that the usability of test fixture is more stable, for the resonance test can provide necessary condition by the repeated experiment and the correlativity experiment of measuring.
The quality of worktable 1 is bigger more than 100 times than the quality of bogie, be far longer than the quality of bogie with the quality that guarantees the resonance measuring anchor clamps, can be so that worktable 1 be very big with the difference degree of bogie quality, to such an extent as to can ignore, guarantee the accuracy of measurement result thereby the influence of the resonance of 1 pair of bogie of worktable is very little.
In the utility model, the course of work that vibration characteristics is measured is: laser beam emitting head sends parallel rays, be radiated on the bogie, voice coil motor sends pumping signal and is delivered to bogie, laser sensor induction bogie vibration situation, by the software processes laser signal, through display device output vibration performance figure.
Use the method for the measured material of the utility model hard disk driving frame to generally comprise following steps:
(1) measured material is placed on the vibration-free tables, guarantees that worktable 1 bottom surface of measured material steadily contacts with the vibration-free tables plane.
