Abstract

The utility model discloses a square inner frame type quadrupole bar support and a device thereof which are used in mass spectrometry type instruments. The square inner frame type quadrupole bar support comprises four precision pole bars and a pair of supports for fixing the four pole bars. The supports are high-precision square inner frame type supports, and the pole bars are arranged at four right angles of a square inner frame of the supports respectively. By adopting the high-precision square inner frame type quadrupole bar support, the difficulty in processing a cylindrical positioning surface and the technical difficulty of completely relying on manual adjustment are avoided, the quality and the qualification rate of a finished product are improved and the processing cost is reduced.

Description

The quadrupole rod support and the device of frame in the square

Technical field

The utility model relates to a kind of quadrupole rod support and device that is used for the mass spectrum quasi-instrument.

Background technology

The quadrupole rod device is the essential core component of mass spectrum quasi-instrument, and its manufacture level has determined the level of a whole set of instrument.And the precision of quadrupole rod mounting bracket is the key point of quadrupole rod device precision.

Desirable quadrupole rod device is made up of a pair of positioning accuracy high ceramics bracket and four high cylindrical utmost point bars of rack-mount shape and size precision, and four cylindrical utmost point bars are symmetrically distributed at directions X and Y direction respectively.The size shape precision of four utmost point bars itself, the degree of being parallel to each other between them, the symmetry on X, Y direction etc. must reach very high required precision (being generally the 1-8 micron).

At present, the primary structure pattern of quadrupole rod device is the position that fixes four utmost point bars with four cylindrical locating surfaces with exact position.This class formation is high for the size shape required precision in the positional precision of location hole and hole, and processing and assembling adjustment difficulty are all very big.Also have some to lean on artificial scheme of assembling adjustment in addition, but will realize the nano-grade size positional precision of quadrupole rod support and device, difficulty is bigger.

The utility model content

For solving the problems of the technologies described above, the utility model proposes a kind of be convenient to process, adjust quadrupole rod support and device easy and the interior frame of square that precision is high.

The quadrupole rod support of frame in a kind of square that the utility model proposes; It is by pair of long edges frame and pair of short edges frame; Firmly be connected through the supporting bracket of eight bolt groups with an annular, formation one has the annular support frame of square inside casing, and this square inside casing is made up of accurate plane, four limits.

Wherein, described long margin frame, minor face frame and supporting bracket are by ceramic material.

A kind of quadrupole rod device that has frame in the square of the utility model proposition, it comprises the utmost point bar of four precisions and the quadrupole rod support of the interior frame of a pair of high accuracy square of fixing these four utmost point bars.Said utmost point bar is located at the place, four right angles of the square inside casing of said support respectively, and is connected with described stand frame through hold-down screw.

The utility model adopts the quadrupole rod support and the device of frame in the square, is prone to realize designing requirements such as dimensional accuracy, the depth of parallelism, perpendicularity between the four limit precision planes of the square inside casing of stand frame.So just avoid the difficulty of processing of cylindrical locating surface and the technical difficulty of leaning on artificial adjustment fully, improved the quality and the qualification rate of finished product, reduced processing cost, and the higher required precision of adjustment realization can be through assembling the time.Use two quadrupole rod supports, distance suitably distributes, and cooperates with the cylindrical utmost point bar of fastening four precisions of screw again, can be assembled into high-precision quadrupole rod device, the finished product high conformity, and precision is high, and cost is low.

Description of drawings

Below in conjunction with embodiment and accompanying drawing the utility model is elaborated, wherein:

Fig. 1 is the sketch map of the utility model preferred embodiment;

Fig. 2 is the right side view of Fig. 1.

Embodiment

Fig. 1 and Fig. 2 show the formation of the utility model preferred embodiment.The quadrupole rod support of frame in the described square; Firmly be connected with the supporting bracket 4 of an annular through eight bolt groups 5 that annular is provided with pair of short edges frame 3 by pair of long edges frame 1; Formation one has the annular support frame of square inside casing, and this square inside casing is made up of accurate plane, four limits.Utmost point bar 2 is fixedly connected with stand frame through hold-down screw 6.And long margin frame 1, minor face frame 3 and supporting bracket 4 are by ceramic material.

The described quadrupole rod device that has frame set in the square comprises the utmost point bar 2 of four precisions and the quadrupole rod support of the interior frame of a pair of high accuracy square of fixing these four utmost point bars.Said utmost point bar 2 is located at the place, four right angles of the square inside casing of this support respectively, and is fixedly connected with described stand frame through hold-down screw.

The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection range of the utility model.
