Abstract
The utility model discloses a surface accuracy testing tool of workpieces, which can conveniently test the surface accuracy of the workpieces mounted in narrow spaces. The technical scheme adopted by the utility model is that the testing tool comprises a bore dial indicator and reference blocks, wherein, a probe module is fixedly mounted between the reference blocks, and the probe in the probe module is connected with an extension bar through a bell crank lever; and the extension bar is connected with the probe of the bore dial indicator. The testing tool provided by the utility model has a simple structure, and can conveniently test the surface accuracy of the workpieces mounted in the narrow spaces.
Description
Technical field:
The utility model relates to testing tool, particularly a kind of surface of the work accuracy detection instrument.
Background technology:
It is the detection operation that enterprise often need carry out that the surface accuracy of workpiece detects; And detecting instrument is mainly dial bore gage; But, should not in small space, detect, if workpiece transfer is detected to other positions again to workpiece because the volume of dial bore gage is bigger; Such detection operation has just caused a lot of restrictions to the environment that detects, and the detection of workpiece is caused a lot of inconvenience.
Summary of the invention:
The purpose of the utility model is that a kind of being convenient to of design carried out the surface of the work accuracy detection instrument that surface accuracy detects to the workpiece that is installed in the small space.The technical scheme of the utility model is; A kind of surface of the work accuracy detection instrument; It comprises dial bore gage, and reference block is characterized in that: between reference block, be installed with probe module; Be connected through bell crank between probe in the probe module and the extension rod, extension rod is connected with the detecting head of dial bore gage.The utility model is simple in structure, can conveniently detect for the surface of the work precision that is installed in the small space.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Describe embodiment in detail in conjunction with accompanying drawing, a kind of surface of the work accuracy detection instrument, it comprises dial bore gage 1; Reference block 5; Between reference block, be installed with probe module 7, be provided with probe 6 in the said probe module, be set with spring on the probe through screw 4; Be connected through bell crank 3 between the top of the probe in the probe module and the extension rod 2, extension rod is connected with the detecting head of dial bore gage.The utility model can be owing to the use of extension rod; Make that dial bore gage can be in that the surface accuracy to workpiece detects from workpiece position far away; Even and workpiece is installed in the small space, also can probe be stretched into the surface of the work that needs to detect and detect, the utility model is simple in structure; Person easy to use manipulates, and has improved the detection efficiency of workpiece.
