Abstract

The utility model relates to the technical field of instrument and equipment detection, in particular to a stepped plug gauge calibrating device, which comprises a base, a gantry support, a plug gauge support seat, a CCD camera and a camera support; the gantry support is fixed on the base, two connecting columns are fixed on the inner side of the gantry support, the camera supports are fixed on the connecting columns through fastening sleeves, the number of the CCD cameras is four and is divided into two groups, each group of two CCD cameras are oppositely arranged on the camera support from top to bottom, and the two plug gauge supporting seats are located on the front side of the gantry support and are fixed on the base. This device simple structure measures the examination through the big or small end of four CCD cameras can be quick to the plug gauge, and examination speed is fast, and work efficiency is high.

Description

Step-type plug gauge calibrating device

Technical Field

The utility model relates to an instrument and equipment detects technical field, especially relates to a cascaded plug gage calibrating installation.

Background

In the manufacturing and inspection industry of mechanical parts, plug gauges are generally used for inspecting the inner diameter of a hole with high precision requirement on parts, and whether the aperture of the inspected hole meets the design requirement can be judged quickly and accurately through simple operation. The general plug gauge is generally a cylinder in appearance at present, the middle part (with anti-skidding knurls) is a handle, and the raised parts at two ends are used for inspection and named as a through end and a stop end respectively. The tolerance of the inspected hole is usually small, so that the through end and the stop end cannot be distinguished easily from the sizes of the two ends by naked eyes. The plug gauge can form certain wearing and tearing with the interact between the measuring part after using a period, lead to follow-up measurement inaccurate, so need examine and determine it at a time interval, to general cylinder plug gauge only need through slide caliper rule measure several external diameters can, but to the plug gauge of notch cuttype, need measure the diameter of little end earlier and measure the diameter of main aspects again, calculate the measurement difference between the two, thereby judge whether qualified, this kind of mode is relatively slow, measure accurate inadequately.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the not enough of above-mentioned technique, and provide a cascaded plug gauge calibrating installation.

The utility model discloses a realize above-mentioned purpose, adopt following technical scheme: the utility model provides a cascaded plug gauge calibrating installation which characterized in that: the device comprises a base, a gantry support, a plug gauge support seat, a CCD camera and a camera support; the gantry support is fixed on the base, two connecting columns are fixed on the inner side of the gantry support, the camera supports are fixed on the connecting columns through fastening sleeves, the number of the CCD cameras is four and is divided into two groups, each group of two CCD cameras are oppositely arranged on the camera support from top to bottom, and the two plug gauge supporting seats are located on the front side of the gantry support and are fixed on the base.

Preferably, the camera support is provided with an adjusting hole.

Compared with the prior art, this device simple structure, can be quick measure the examination to the big or small end of feeler gauge through four CCD cameras, examination is fast, and work efficiency is high.

Detailed Description

Spatially relative terms such as "above … …", "above … …", "above … …", "above", and the like, may be used herein for ease of description to describe the spatial relationship of one feature or characteristic to another feature or characteristic as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

As shown in fig. 1 and 2, a stepped plug gauge calibrating device comprises a base 1, a gantry support 2, a plug gauge support base 3, a CCD camera 4 and a camera support 5; the gantry support is fixed on the base, two connecting columns 6 are fixed on the inner side of the gantry support, the camera supports are fixed on the connecting columns through fastening sleeves, the number of the CCD cameras is four and is divided into two groups, each group of two CCD cameras are oppositely arranged on the camera support from top to bottom, and the two plug gauge supporting seats are located on the front side of the gantry support and are fixed on the base. In order to adjust the height of the CCD camera, the camera bracket is provided with an adjusting hole.

As shown in figure 3, during the use, place feeler gauge 7 on the feeler gauge supporting seat, adjust the position of four CCD cameras, make upper and lower two sets of CCD cameras be located the upper and lower both sides of feeler gauge respectively, take a picture respectively to every stage of feeler gauge, once take a camera support of removal, integration and the picture that has stored of photo are compared through the system, thereby judge whether qualified feeler gauge, this device utilizes the principle of image template matching, take a picture to the cascaded feeler gauge surface of volume of awaiting measuring through four CCD cameras, match with the feeler gauge shape and size in the system again, thereby judge whether qualified of the whole size of feeler gauge, it is fast to examine and determine, high work efficiency.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
