Detailed Description

The present invention will be further explained with reference to the accompanying drawings and specific embodiments, but it should be noted that the present invention is not limited to the specific embodiments.

As shown in fig. 1 to 3, the suspension type measuring stand of the grinding machine provided by the present embodiment includes a suspension bracket 1, an auxiliary fixing frame 2, an inverted T-shaped cylinder 3, a first disk 4, a disk fixing frame 5, a second disk 6, a transmission measuring rod 7, a return spring 8, and a display meter 9.

The auxiliary fixing frame 2 is movably connected with one side of the suspension frame 1 to form a C-shaped clamping shape, the bottom end of the transmission measuring rod 7 is clamped into the reset spring 8 and movably penetrates out of the bottom end of the other side of the suspension frame 1 to be connected with the inverted T-shaped cylinder 3, the inverted T-shaped cylinder 3 is a main measuring point, an 1/4 arc-shaped projection 301 is horizontally arranged at the bottom end of the inverted T-shaped cylinder 3, the display meter 9 is installed at the top of the other side of the suspension frame 1, and a measuring head of the display meter is abutted to the top end of the transmission measuring rod 7. The display 9 is a dial indicator or a dial indicator. The display gauge 9 has the function of converting the measured journal diameter size into a reading of a dial gauge or a reading of a dial gauge by mechanical transmission of the transmission measuring rod 7. The purpose of arc lug 301 is because of the display list through transmission measuring stick mechanical transmission, and in the conversion process, the angle of rotation can appear in type of falling T cylinder 3, influences the measuring accuracy nature, and arc lug 301 plays and avoids leading to the effect that the measurement size exists the error.

Specifically, as shown in fig. 3, the suspension bracket 1 is formed by connecting a fixed block 101, a square column 102 and a bump 103 with a hole, the bottom of the fixed block 101 is provided with an inclined plane 104 and fixed on one side of the bottom of the square column 102, the bump 103 with a hole is arranged on one side of the top of the square column 102, the auxiliary fixed bracket 2 is formed by connecting a vertical part 201, a slope part 202 and a horizontal part 203, the vertical part 201 is connected to the top of the slope part 202, and the bottom of the slope part 202 is connected to the horizontal part 203. The vertical part 201 of the auxiliary fixing frame 1 movably penetrates through the fixing block 101 of the suspension frame 1 and is fastened through bolts, so that the auxiliary fixing frame 2 can adjust the distance between the horizontal part 203 and the square column 102 of the suspension frame 1 through adjusting the tightness of the bolts. The slope part 202 of the auxiliary fixing frame 2 and the inclined surface 104 of the suspension frame 1 are opposite to form a C-shaped clamping shape, and the horizontal part 203 of the auxiliary fixing frame 2 is parallel to and corresponds to the bottom end of the square column 102.
