Detailed Description

The invention is described in further detail below with reference to the following figures and specific embodiments:

the invention discloses a cylinder roundness detection tool, which is mainly used in constructional engineering, is a detection tool and can be applied to cylinder roundness detection in other industries.

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 invention uses the sliding graduated scale 2 to measure the cylinder to be detected, and the sliding graduated scale 2 can be set as a dial indicator. 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.

As shown in fig. 1 and 2, two holding holes 32 are provided, and two fixing bolts 1 are provided. The hand-held hole 32 is located at the other end opposite to the fixing bolt 1. The handheld tray table 3 can be regarded as a rectangular plate, and a semicircular groove is formed in the rectangular plate. The hand-held hole 32 is formed at one end of the rectangular plate, and the fixing bolt 1 is disposed at the other end of the rectangular plate. The direction of the two fixing bolts 1 is arranged along the diameter of the semicircular groove.

In order to improve the stability of the handheld pallet 3 during measurement, a handheld adjusting rod 4 is hinged to the other side face of the handheld pallet 3 opposite to the horizontal bubble. When the handheld adjusting device is used, a worker holds the handheld adjusting rod 4 to adjust the balance of the handheld saddle 3. After the balance is adjusted, the hand-held adjusting rod 4 is kept still, so that the hand-held saddle 3 can keep balance in the measuring process.

The inspection tool of the invention is provided with the handheld tray table 3 as a main body bracket, and because the handheld tray table 3 needs to be held by a worker for operation, the integral quality of the inspection tool can be reduced by preferentially manufacturing the handheld tray table 3 by using high-strength plastics.

In the actual use process, through measuring the unwrapping wire, according to drawing size and position, with fixing bolt 1 with the device be fixed in the cylinder 5 that awaits measuring, and guarantee that the line between fixing bolt 1 passes through the cylinder axle center. The operator holds the hand-held hole 32 while moving the sliding scale 2 along the arc-shaped track 32. 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 method described above is still used for the other half of the column. The sliding scale 2 can detect the roundness of the section of the column 5 in all directions in the process of moving around the column 5.

When the invention is processed and manufactured, series products with different specifications can be manufactured, and the specification is defined according to the size of the semicircular groove on the handheld saddle 3. When the detection tool of the same specification corresponds to a cylinder to be detected with similar size, different fixing bolts 1 and sliding graduated scales of measuring rods with different lengths are selected to meet the use requirements. For example, the semi-circular groove of the handheld pallet 3 has a diameter of 265mm, which is capable of measuring cylinders having a diameter in the range of 200mm-260 mm. If the sliding graduated scale can not meet the use requirement, only the sliding graduated scale is replaced.
