本实用新型涉及一种圆柱工件圆柱度检测装置。本实用新型包括底座，其特征在于所述的底座上设置两个呈一定角度的基准面，与基准面相对的一侧设置限位装置，所述的限位装置与基准面之间夹持待测工件，所述的底座上还设置用于检测工件的测头。本实用新型用专用检测装置将圆柱工件紧贴于基准面，并将百分表和底座固定，同时测头测在圆柱工件外圆面上。配合旋转移动圆柱工件使测头进出，读取百分表上指示范围(极差＝最大值－最小值)，此极差为其圆柱度。
The utility model relates to a cylindricity detection device for cylindrical workpieces. The utility model includes a base, which is characterized in that two reference planes at a certain angle are arranged on the base, and a limit device is arranged on the side opposite to the reference plane, and the position-limiting device and the reference plane are clamped to be To measure the workpiece, the base is also provided with a measuring head for detecting the workpiece. The utility model uses a special detection device to closely adhere the cylindrical workpiece to the datum surface, fix the dial indicator and the base, and measure the measuring head on the outer surface of the cylindrical workpiece at the same time. Move the cylindrical workpiece with the rotation to make the probe go in and out, read the indicated range on the dial indicator (range=maximum value-minimum value), and the range is its cylindricity.
Description
Technical field
The present invention relates to cylindrical workpiece processing technique field, particularly periphery cylindricity pick-up unit after a kind of cylindrical workpiece periphery processing.
Background technology
Behind cylindrical workpiece processing excircles face, its periphery cylindricity is the project of a more difficult detection, and periphery cylindricity is extremely important test item, is to detect one of its whether qualified important indicator.As shown in Figure 1, existing detection scheme generally adopts outside diameter measuring instrument (outside micrometer) to measure the outside dimension of each position of cylindrical workpiece, then reads each and detects data, get extreme difference (maximal value-minimum value) ≈ cylindricity.Namely need the size measuring multiple (General Requirements 4 sizes) position at cylindrical workpiece periphery, and write down measurement result, then obtain its cylindricity by calculating.
This detection scheme needs at least to measure 4 data, and (for guaranteeing each measurement data accuracy, suggestion is each measures 3 times, averages.), and read and record measurement result, obtain its cylindricity by calculating, testing process is loaded down with trivial details, complicated, inefficiency.
Utility model content
The utility model, for the problems referred to above, provides a kind of cylindrical workpiece cylindricity pick-up unit, significantly promotes detection efficiency, and judge that whether qualified it is.
For this reason, the utility model takes following technical scheme, a kind of cylindrical workpiece cylindricity pick-up unit, comprise base, it is characterized in that described base being arranged two reference fields at an angle, the side relative with reference field arranges stop means, clamps workpiece for measurement between described stop means and reference field, described base is also arranged the gauge head for detecting workpiece.
Described stop means comprises spring, and spring outwards connects steel ball, and described steel ball and workpiece for measurement are fitted.
Described stop means is symmetrical set, and is at least two, and the angle that two described stop means are formed is less than the angle between two reference fields.
Two described reference fields are 90 degree.
The external dial gauge of described gauge head.
Cylindrical workpiece is close to reference field by the utility model special detection device, and dial gauge and base is fixed, and gauge head is surveyed on cylindrical workpiece periphery simultaneously.Coordinate cylindrical workpiece in rotary moving that gauge head is passed in and out, read indicating range (extreme difference=maximal value-minimum value) on dial gauge, this extreme difference is its cylindricity.The utility model has the following advantages:
1, cylindrical workpiece convenient fixing, testing process is easy, alleviates working strength;
2, increase work efficiency, directly can read measurement result (cylindricity);
3, detect accurately, effectively ensure product percent of pass;
4, reference field adopts high-abrasive material, can increase the service life; And reference field is dismantled and assembled, be convenient to revise and exchange;
5, can Aulomatizeted Detect being realized, realizing robotization by increasing several simple workpiece such as microcomputer, electronics gauge head.
Accompanying drawing explanation
Fig. 1 is the structure schematic diagram of existing detection scheme knot
Fig. 2 is structure of the detecting device schematic diagram of the present utility model.
Embodiment
Below in conjunction with specific embodiment, set forth the utility model further.
A kind of cylindrical workpiece cylindricity pick-up unit as shown in Figure 2, base 2 arranges two reference fields 3 in an angle of 90 degrees, the side relative with reference field 3 arranges stop means, workpiece for measurement 1 is clamped between stop means and reference field, base 2 is also arranged the gauge head 6 for detecting workpiece, the external dial gauge 7 of gauge head 6.
Stop means comprises spring 5, screw, connects steel ball 4 outside spring 5, and steel ball 4 and workpiece for measurement 1 are fitted.Stop means is symmetrical set, and is at least two, and can arrange many groups in vertical direction, and the angle of two stop means formation is less than the angle between two reference fields.
Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model instruction.
