Problems solved by technology

[0003] However, the steps of the above method are too cumbersome and the efficiency is low; the combination ruler or steel ruler used has high requirements, if there is wear and tear, the test results will be affected, and the measuring tools need to be replaced continuously, resulting in waste; in addition, the parts are in difficult positions. When, too many steps make the operation difficult and the efficiency is lower
[0004] In addition, during assembly, it is necessary to locate the center of the hole before assembling. Due to the cumbersome marking of the prior art, the assembly time is long and the efficiency is low.

Embodiment 1

[0034] Such as figure 1 with 2 As shown, a quick scribing positioning device for the center of a hole includes a polyurethane round rod 1 that can be inserted into the hole 8. The outer diameter of the polyurethane round rod 1 is larger than the diameter of the hole 8, and the side wall of the polyurethane round rod 1 is provided with a concave Groove 2, due to the flexibility of the polyurethane material, when inserted into the hole 8, even if the outer diameter of the polyurethane rod 1 is larger than the diameter of the hole 8, in the presence of the groove 2, the side wall of the polyurethane rod 1 can be deformed or Bending enables the polyurethane round rod 1 to be inserted into the hole 8 and ensures a close fit with the hole 8. Specifically, the outer diameter of the polyurethane round rod 1 is 0-0.5mm larger than the diameter of the hole 8, which is convenient to operate and has a good matching effect; The upper end surface 4 of the polyurethane round rod 1 is engraved ...

Embodiment 2

[0039] This embodiment protects a hole center deviation inspection method. Specifically, the inspection is performed by using a hole center quick marking positioning device, which includes the following steps:

[0040] Step 1: Select at least two identical devices;

[0041] Step 2: Insert the device into different holes 8 on the part 9 with holes, so that the upper end surface 4 of the device is level with the surface of the part 9;

[0042] Step 3: According to the different arrangement of the holes 8, select the center of the upper end surface 4 connecting the same row or opposite devices, and check whether the hole centers on the same straight line with the two devices connected to each other are offset;

[0043] Step 4: Repair the offset hole 8 to meet application requirements.

[0044] Further, in step 2, the specific arrangement of the device is not limited, and it is sufficient to check whether the center of the hole is offset, specifically, such as image 3 As shown, any two dev...

Abstract

The invention discloses a hole centre rapid marking-positioning device and a hole centre bias check method, and relates to the technical field of hole centre marking. The hole centre rapid marking-positioning device comprises polyurethane round rods capable of inserting in holes, wherein the outer diameter of each polyurethane round rod is greater than the diameter of the corresponding hole; grooves are formed in the sidewall of each polyurethane round rod; and cross lines with an intersection point which passes through the circle centre of the upper end surface are engraved on the upper end surface of each polyurethane round rod. The invention further discloses a hole centre bias check method, and said hole centre check device is used for check. The hole centre rapid marking-positioning device and the hole centre bias check method, which are disclosed by the invention, are capable of realizing rapid marking-positioning for hole centres, capable of conveniently and rapidly detecting whether the hole centres are biased or not, high in detection accuracy, and suitable for being applied in various construction fields.

Description

Technical field [0001] The invention relates to the technical field of hole center marking, in particular to a hole center quick marking positioning device and a hole center deviation inspection method. Background technique [0002] The steel structure and shipbuilding industry are inseparable from the bolted connection structure. Most of the structures connected by bolts are provided with rows of multiple holes. First, drilling is required. After drilling, it is necessary to check whether these holes are offset. In the prior art, detection is mainly performed through multi-step scribing through a combination ruler or a steel ruler. [0003] However, the steps of the above method are too cumbersome and low in efficiency; the combined ruler or steel ruler used has high requirements. If wear occurs, the test result will be affected, and the measuring tool needs to be replaced continuously, causing waste; in addition, the parts are in a difficult to operate position At times, too man...
