The utility model has the advantages of large table top, strong applicability, and high reliability, and furthermore, the utility model is suitable for high precision measurement.
Description
The utility model relates to a kind of workbench of measuring instrument, relates in particular to a kind of workbench of vertical measuring instrument.
Therefore measuring instrument is the instrument that generally uses when measuring precision component in industrial production and the scientific research because its measurement is convenient, accurate.The workbench of existing measuring instrument is that a kind of type instrument disposes a kind of workbench substantially, and versatility is poor, and table top is less, and the measured piece that can not adapt to various geometries is measured; Do not have adjusting device besides, influence certainty of measurement.
The purpose of this utility model is exactly in order to overcome the shortcoming of existing measuring instrument workbench, and the big plane high accuracy multipurpose surveying work platform of a kind of simple in structure, the highly versatile that provides.
The purpose of this utility model is achieved in that a kind of big plane high accuracy multipurpose surveying work platform, comprises test desk, and column and support, described column vertically are installed in test desk one side, and support casing is located on the column, adopts trip bolt to fix; It is characterized in that: described test desk is for double-deck, the upper strata is adjustable test desk, lower floor is a base, the relative conical socket that respectively is provided with in the bottom of adjustable test desk with the face of base, be embedded one therebetween and can make between adjustable test desk and base the steel ball that keeps certain interval, equidistantly around the steel ball be provided with four extension springs and hold base and test desk respectively; The centre of sphere of described steel ball is being measured on the axis; Described adjustable test desk one side is provided with the lock-screw that is connected with base, and corresponding spiral shell establishes the horizontal level adjustment screw that two bottoms can be against the base face, and these the two horizontal level adjustment screw and the steel ball centre of sphere are in quadrature position; Described column vertically is installed in the base inboard; Also comprise a support position-limit mechanism, be made of a limit base, an adjustment seat and a fine setting circle that limit base is installed in the below that is in support on the column by lock-screw, the top of limit base is provided with external screw thread, and the fine setting circle is arranged on this external screw thread; Adjustment seat be enclosed within on the column and seat on limit base.
Described big plane high accuracy multipurpose surveying work platform, wherein: the horizontal level adjustment screw respectively is provided with one near the side of steel ball and stablizes extension spring, and this two stablizes extension spring and the steel ball centre of sphere is in quadrature position.
Because the utility model has adopted above structure, establishes a ball and two adjustment screw between test desk and base, makes the perpendicularity of measured piece and workbench adjustable, adapt to high-acruracy survey, table top amplifies, and measures but the clamping diameter is all measurer amount instrument of 8mm, adaptability is strong, the reliability height.
Concrete structure of the present utility model is further provided by following embodiment and accompanying drawing thereof.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
See also accompanying drawing:
A kind of big plane of the utility model high accuracy multipurpose surveying work platform, comprise test desk, column and support, described test desk is double-deck, the upper strata is adjustable test desk 11, and lower floor is a base 12, the relative conical socket 111,121 that respectively is provided with of face of the bottom of adjustable test desk 11 and base 12, be embedded one therebetween and make the steel ball 2 that keeps certain interval between adjustable measurement and base, the centre of sphere of described steel ball 2 is being measured on the axis; A side is provided with and is connected locking screw 3 between described adjustable test desk and the base, equidistant is provided with four Locating extension springs 4 all around.Establish the horizontal level adjustment screw 5 that a bottom can be against the base face at adjustable test desk opposite side spiral shell; By regulating adjustment screw and extension spring, can make whole table surface keep vertical with column or measuring staff in the position of orthogonal direction.
Described horizontal level adjustment screw respectively is provided with one near the side of steel ball and stablizes extension spring 10, and this two stablizes extension spring and the steel ball centre of sphere is in quadrature position.
Described column 6 vertically is installed in base 12 inboards; Support 7 is set on the column 6, adopts trip bolt 71 fixing, and measuring staff 9 is set on support.For preventing the support landing, avoid the gage outfit 91 on the measuring staff to damage, the utility model also comprises a support position-limit mechanism 8, is made of a limit base 82, an adjustment seat 83 and a fine setting circle 84; Limit base is fixed on the column by lock-screw 81, is in the below of support; Adjustment seat is enclosed within on the column, and seat is on limit base.The limit base top is provided with external screw thread, and the fine setting circle is arranged on the external screw thread of limit base, and the rotary fine adjustment circle can be regulated the upper-lower position of adjustment seat, thereby reaches the initial position between control survey head and the measurement table top.
