Drawings
The utility model is described in further detail below with reference to the attached drawings and detailed description:
Fig. 1 is a schematic structural view of the present utility model.
Detailed Description
As shown in fig. 1, the special gauge for quickly measuring the verticality and the roundness of a cylinder hole of the cylinder comprises a bottom plate 1, a pull rod 2, a pressure head 3, a bearing 4, a positioning ring 5 and a dial indicator 6, wherein a first supporting plate 7 and a second supporting plate 8 which are arranged at intervals are fixed on the bottom plate 1, the middle part of the pull rod 2 is movably sleeved on the first supporting plate 7, one end, facing the second supporting plate 8, of the pull rod 2 is fixedly connected with the pressure head 3, the other end of the pull rod 2 is fixedly provided with a handle 9, and a compression spring 10 sleeved on the pull rod 2 is connected between the pressure head 3 and the first supporting plate 7.
The bearing 4 is connected to the second support plate 8, the outer ring of the bearing 4 is fixed to the second support plate 8, and the positioning ring 5 is fixedly sleeved in the inner ring of the bearing 4 through screw connection. The above structure can realize the rotation movement of the positioning ring 5.
The bottom plate 1 is fixed with a guide rail 11, the guide rail 11 is connected with a meter frame 12 in a sliding manner through a sliding seat, the dial indicator 6 is fixed on the meter frame 12, the position of the dial indicator 6 on the meter frame 12 is adjustable (the meter frame 12 is of a cross structure, two brackets are respectively provided with a long strip-shaped hole, and the position of the dial indicator can be adjusted by penetrating the two long strip-shaped holes through bolts and locking and connecting with nuts). The gauge stand 12 moves along the guide rail 11 to drive the dial gauge 6 to move in a direction approaching or separating from the positioning ring 5.
One end of the pressure head 3 is provided with a threaded portion, and the threaded portion is in threaded connection with a corresponding threaded hole in the pressure head 3.
During detection, the cylindrical surface of the outer side of the cylinder hole part at the bottom of the cylinder 13 is positioned and sleeved in the positioning ring 5, and the pressure head 3 is pressed in the groove at the head part of the cylinder 13.
Taking the flange surface of the cylinder 13 as a reference, pushing the dial indicator 6 along the guide rail 11, enabling the gauge needle of the dial indicator 6 to move back and forth on the wall of the cylinder hole of the cylinder 13, looking at the change of the gauge needle, judging that the perpendicularity of the cylinder hole is qualified if the gauge needle is stable (the numerical value change indicated by the gauge needle is within a preset range), otherwise, judging that the perpendicularity is bad. After the measurement is carried out by taking the flange surface of the cylinder 13 as a reference, the cylinder hole of the cylinder 13 to be measured is rotated along the bearing 4, the change of the gauge needle is observed, and if the gauge needle is stable (the numerical value change indicated by the gauge needle is within a preset range), the cylinder hole circle of the cylinder 13 is judged to be qualified, otherwise, the cylinder hole circle is judged to be bad.
While particular embodiments of the present utility model have been described above, it will be understood by those skilled in the art that this is by way of example only, and that various changes and modifications may be made to this embodiment without departing from the spirit and scope of the utility model, but these changes and modifications are within the scope of the utility model.
