Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific embodiments:
the utility model discloses a cylinder roundness detection instrument, among the mainly used building engineering, be a detection instrument, also can use on the cylinder roundness detection of other trades.
As shown in fig. 1 and 2, the cylinder roundness detection tool includes a handheld mount 3, a sliding scale 2, and a fixing bolt 1. The handheld saddle 3 is a main body support part of the tool, the handheld saddle is of a 3-bit plate-shaped structure, and the sliding graduated scale 2 is arranged on the handheld saddle 3. The handheld saddle 3 is provided with a semicircular groove which can be matched with the cylinder 5 to be measured, the fixing bolt 1 is arranged on the outer side of one end of the opening of the semicircular groove, and the fixing bolt 1 is used for clamping and fixing the handheld saddle 3 and a column head to be detected. The number of the fixing bolts 1 is at least two, and the two fixing bolts 1 are oppositely arranged on two sides of the opening of the semicircular groove.
The detection tool uses a sliding scale 2 for specific measurement work. The sliding scale 2 is arranged on the handheld saddle 3 and can slide, and changes of measured data are observed through sliding, so that measurement and inspection of the roundness of the cylinder are realized. In order to enable the sliding scale 2 to perform sliding measurement regularly and accurately. An arc-shaped track 31 used for guiding and limiting the sliding scale 2 is arranged on the handheld saddle 3, and the arc-shaped track 31 is arc-shaped and is arranged along the outline of the semicircular groove. The concrete structure is shown in figure 1.
In a specific implementation, the arc-shaped track 31 may be a convex track or a through groove structure, preferably, the arc-shaped track 31 is an arc-shaped through groove structure, and correspondingly, a guide block capable of being matched with the arc-shaped track 31 is arranged on the lower surface of the sliding scale 2; in use, the guide block slides within the arcuate track 31. The sliding scale 2 and the arc rail 31 are not connected but only in a contact guiding relationship, so that the sliding scale 2 can be easily replaced.
The utility model discloses use slip scale 2 to treat and detect the cylinder and measure, slip scale 2 can set up to the percentage table. During measurement, the sliding scale 2 is moved along the arc-shaped track 31. In the moving process of the sliding graduated scale 2, an operator continuously records the numerical value of the sliding graduated scale 2 when the cylinder is tightly jacked, and the roundness of the measured cylinder is directly obtained by recording the change of the numerical value and the numerical value. The preparation before measurement is the preparation before the dial indicator is measured.
In order to facilitate the worker to perform the handheld operation, a handheld hole 32 is formed in the handheld pallet 3 in a penetrating mode, and the worker holds the handheld hole 32 to ensure that the handheld pallet 3 is balanced. Further, can be at the fixed horizontal bubble that sets up in handheld pallet 3 one side, whether can audio-visually know handheld pallet 3 in the horizontality through the horizontal bubble, if not in the horizontality, can adjust according to the instruction of horizontal bubble.
