A kind of large scale face depth of parallelism special measurement instrument
Technical field
The utility model relates to a kind of depth of parallelism measurer, particularly relates to a kind of large scale face depth of parallelism special measurement instrument.
Background technology
The measurement of face and the face depth of parallelism in machining, generally adopt and ensure reference field level with V-block on measuring table, then measure the full surface of measured surface with dial gauge, its maximum difference is the measured value of the depth of parallelism; Or the relative size between two surfaces measured by direct outside micrometer, its maximum difference is the measured value of the depth of parallelism.But at extreme large and heavy workpiece, the column as numerical control vertical lathe adds man-hour, need two surperficial areas measuring very large, generally at (6000 ~ 10000) about mm × 250mm, the depth of parallelism requires as 0.03mm.For the parallel surfaces of this heavy parts, adopt conventional method cannot realize measuring.
Summary of the invention
The utility model provides a kind of large scale face depth of parallelism special measurement instrument, can realize the measurement of the depth of parallelism between large-scale workpiece two parallel surfaces, and structure is simple, and array configuration is various, easy to use and flexible, measures efficiency high.
In order to achieve the above object, the utility model realizes by the following technical solutions:
A kind of large scale face depth of parallelism special measurement instrument, comprise connecting rod, 2 chucks, positioning head and dial gauges, described 2 chucks be arranged in parallel, and chuck one end is fixed on connecting rod movably, and the other end is fixedly connected with positioning head and dial gauge respectively.
Described positioning head working surface is provided with ball.
Described chuck is Split type structure, by the screw that is located at two ends closing, and realizes and being fixedly connected with of connecting rod and positioning head.
The endoporus that described chuck coordinates with connecting rod, positioning head or dial gauge is axially arranged with 1 ~ 3mm gap along chuck.
Described positioning head ball side and dial indicator measuring head side can be relative, opposing or arrange in the same way according to measured workpiece two parallel surfaces relative position.
Compared with prior art, the beneficial effects of the utility model are:
1) general measuring method is difficult to the large scale surface depth of parallelism of the large-scale workpiece maybe cannot measured, can measures quickly and easily, significantly improve work efficiency;
2) realize multiple combination metering system by the installation direction of adjustment positioning head and dial gauge, all can easily measure for two side external surfaces, both sides inside surface or same surface;
3) structure is simple, and easy to manufacture, applicability is strong.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
See Fig. 1, it is structural representation of the present utility model, a kind of large scale face of the utility model depth of parallelism special measurement instrument, comprise connecting rod 1,2 chucks 2, location 3 and dial gauge 4, described 2 chucks 2 be arranged in parallel, chuck 2 one end is fixed on connecting rod 1 movably, and the other end is fixedly connected with positioning head 3 and dial gauge 4 respectively.
Described positioning head 3 working surface is provided with ball 5.
Described chuck 2 is Split type structure, by the screw 6,7 that is located at two ends closing, and realizes and being fixedly connected with of connecting rod 1 and positioning head 3.
The endoporus that described chuck 2 coordinates with connecting rod 1, positioning head 3 or dial gauge 4 is axially arranged with 1 ~ 3mm gap along chuck 2.
Described positioning head ball 1 side and dial gauge 4 measuring head side can be relative, opposing or arrange in the same way according to measured workpiece two parallel surfaces 8,9 relative position.
The using method of a kind of large scale of the utility model face depth of parallelism special measurement instrument is as follows:
1) be incorporated on connecting rod 1 by chuck 2 handle, chuck 2 top screw 1 connects, and does not first tighten fixing; 2 chuck 2 bottoms install positioning head 3 and dial gauge 4 respectively, and connect with screw 27; Ensure that installing rear chuck 2 still can slide along connecting rod 1;
2) according to the position of spacing determination chuck 2 on connecting rod 1 of measured workpiece two parallel surfaces 8,9, ball 5 on positioning head 3 and dial gauge 4 measuring head contact with tested two surfaces 8,9 respectively possesses measuring condition, tightens fixing behind location by screw 1 and screw 27;
3) positioning head ball 5 one end is close to surface of the work and slowly slides, and it is measured value that dial gauge 4 all directions find smallest point, and multi-point is measured, and getting maximum difference is the depth of parallelism.
Seeing Fig. 2, is the structural representation of chuck 2 described in the utility model.Chuck 2 adopts Split type structure, is divided into the collet body of two structure almost symmetries along axis, and two ends are connected conjunction with screw 27 by screw 1.Wherein collet body screw connecting hole in side is screw, and opposite side collet body screw connecting hole is unthreaded hole, and the unthreaded hole that screw 1 or screw 27 are each passed through side collet body is fixed in the screw of opposite side collet body and achieves a fixed connection.Chuck 2 is after conjunction, and the endoporus for installing connecting rods 1, positioning head 3 or dial gauge 4 axially leaves gap along chuck 2, can make fixing more solid and reliable.
Seeing Fig. 3, is that the utility model is for measuring schematic diagram during the two side external surface depth of parallelisms.Now, positioning head ball 5 side and dial gauge 4 measuring head side are oppositely arranged, and effectively contact with measured surface 29 with measured surface 1 respectively.
Seeing Fig. 4, is that the utility model is for measuring the schematic diagram during inside surface depth of parallelism of both sides.Now, the opposing setting in positioning head ball 5 side and dial gauge 4 measuring head side, and effectively contact with measured surface 29 with measured surface 1 respectively.
Seeing Fig. 5, is that the utility model is for measuring schematic diagram during the two same surface depth of parallelisms.Now, positioning head ball 5 side and dial gauge 4 measuring head side are arranged in the same way, and effectively contact with measured surface 29 with measured surface 1 respectively.
