Specific embodiment

Description is made to the preferred embodiment of the utility model below with reference to the Figure of description provided.

The utility model provides a kind of counterbore detecting device for smoothness, for detecting speaker shell shown in Fig. 1 to Fig. 3 Flatness in several counter sinks 14 on body 1 between step surface 15.

In conjunction with shown in fig. 4 to fig. 6, this counterbore detecting device for smoothness includes pedestal 2, linear drive apparatus 3, monitor station 4 And measurement table 5, pedestal 2 are placed for shell 1, and 2 lower part of pedestal is equipped with the positioning table 23 of positioning housing 1, linear drive apparatus 3 It is set on pedestal 2 with monitor station 4, wherein linear drive apparatus 3 drives opposite about 2 pedestal above positioning table 23 of monitor station 4 Sliding and close to or far from positioning table 23.It measures table 5 and is set to monitor station 4, measurement table 5 has the measuring staff 52 extended downwardly, measuring staff 52 size is less than biggish one section of aperture in counter sink 14 and is greater than lesser one section of aperture in counter sink 14, therefore measuring staff 52 It can be resisted against on step surface 15 in insertion counter sink 14.Measuring staff 52 bounces back along straight line into measurement table 5 after contradicting step surface 15, Its stroke to bounce back is shown as the registration on measurement table 5.Preferably, measurement table 5 is number display dial gauge, thus convenient reading Registration can also be conducive to carry out relevant calculation automatically by being read after connecting measurement table 5 with computer by computer.Measurement Table 5 is also possible to amesdial, ten thousandth micrometer etc., and other can show the measuring tool of reading according to straight-line displacement.

Specifically, pedestal 2 includes the pedestal 21 and stand 22 being fixed to each other, pedestal 21 extends horizontally, and stand 22 is opposite Pedestal 21 is holded up.Positioning table 23 is arranged on pedestal 21, and the quantity several positioning equal with measurement table 5 are offered on positioning table 23 Slot 25, locating slot 25 is used for positioning housing 1, therefore the quantity of locating slot 25 is identical as the quantity of 1 column body 13 of shell, shell 1 Upper there are four cylinders 13, therefore four locating slots 25 are arranged on positioning table 23, the distributing position and shell 1 of four locating slots 25 The distribution mode of upper four cylinders 13 is consistent.Positioning table 23 is slightly less than the opening of 1 one end of shell, is inverted shell 1 and is buckled in It is accommodated in the inner on pedestal 21 and by positioning table 23, it is preferred that be buckled to and be clamped on positioning table 23.Meanwhile four on shell 1 A cylinder 13 can be inserted respectively into four locating slots 25.The cooperation being open by positioning table 23 and shell 1 and locating slot 25 with the cooperation of cylinder 13, it can be achieved that strong fix to shell 1.

Stand 22 is equipped with the guide rail 221 vertically extended towards this of pedestal 21 on one side, and guide rail 221 preferably has phase Mutually spaced apart two, monitor station 4 is slidingly attached on two guide rails 221 by sliding block, and monitor station 4 is made to be located at the upper of positioning table 23 Fang Bingke is slided up and down with respect to pedestal 2.Linear drive apparatus 3 is the cylinder being fixed on pedestal 2, and the piston rod of cylinder is to downward It stretches and passes through a fixed block 42 and fixed with monitor station 4, just drive monitor station 4 to slide up and down when piston rod stretches.Certainly, at it In his embodiment, linear drive apparatus can also be that electric pushrod, motor add other devices such as rack-and-pinion.On monitor station 4 The quantity for measuring table 5 is also identical as the quantity of counter sink 14 on shell 1, is four in the present embodiment, four measurement table 5 difference It is corresponding with four locating slots 25 of lower section.

When being detected, the inversion of 1 bottom plate of shell upward is buckled on positioning table 23, four cylinders 13 are inserted into four respectively It in locating slot 25, then drives monitor station 4 to decline by linear drive apparatus 3, stretches four measuring staffs 52 of four measurement tables 5 respectively Enter into four counter sinks 14.Measuring staff 52 just bounces back into measurement table 5 after measuring staff 52 is contacted with step surface 15, measures on table 5 Occurs registration immediately.In optimal situation, the registration on four measurement tables 5 is consistent, then it represents that this four platforms on shell 1 The flatness of terrace 15 is good.If the deviation of four registrations is in a certain range of very little, then it is also contemplated that shell 1 is qualified Product.Preferably, four measurement tables 5 can be connected to simultaneously on a computer, read by computer, and built-in by calculating Software judges the deviation between several readings, and in conjunction with tolerable error provide automatically whether He Ge conclusion, eliminate manually The process for reading and settling accounts.

Certainly, in addition to voice box casing 1, this counterbore detecting device for smoothness may be additionally used for detecting different on other products Flatness between face.

Preferably, a mounting plate 26 is further fixed between positioning table 23 and stand 22 on pedestal 21, in mounting plate 26 Both ends be respectively fixed with a buffer 7 upward, both ends of two buffers 7 towards 4 bottom surface of monitor station.In the detection process, The monitor station 4 of decline is first contacted with buffer 7, and certain buffer protection is provided by buffer 7, avoids measuring staff 52 and shell 1 hard Property contact and both cause to damage.

Compared with prior art, this counterbore detecting device for smoothness can automatically detect flatness, without manually surveying Amount, solves the problems, such as that large labor intensity, error are big, testing result is more accurate.

Above disclosed is only the preferred embodiments of the utility model, and effect is to facilitate those skilled in the art Understand and implement accordingly, the interest field of the utility model cannot be limited with this certainly, therefore special according to the present utility model application Equivalent variations made by sharp range still falls within the range that the utility model is covered.
