Description

Technical Field

[0001] This utility model relates to an auxiliary device for measuring the dimensions of a blunt edge with burrs, belonging to the field of auxiliary measuring tooling technology. Background Technology

[0002] Currently, when measuring the thickness of plates, pipes, profiles, or other dimensions with burrs or blunt edges at construction sites, it is usually necessary to use a grinder or hand file to remove the burrs or blunt edges from the steel surface before measuring with vernier calipers; or to use an ultrasonic thickness gauge, which requires the use of a coupling agent. This method is cumbersome, easily contaminates hands, and is inconvenient for recording measurement results when operated by a single person. Therefore, the above measurement methods are time-consuming, labor-intensive, and inconvenient. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide an auxiliary device for measuring the size of burred blunt edges, which is used to measure the size of steel with burred blunt edges, without the need for surface treatment of the steel, is easy to use, and improves measurement efficiency.

[0004] The auxiliary device for measuring the dimensions of burrs and blunt edges described in this utility model includes a vernier caliper. The vernier caliper has fixed jaws and movable jaws, and a measuring blade is detachably connected to the fixed jaws and movable jaws. The measuring blade has a tip and is magnetic, so it can be attracted to the jaws of the vernier caliper.

[0005] The technical solution of this utility model is to provide an auxiliary device for measuring the dimensions of burrs and blunt edges. By adsorbing the measuring blade onto the jaws of a vernier caliper, the tip of the measuring blade is brought into contact with the surface of the steel to be measured during measurement. This avoids the jaws of the vernier caliper from directly contacting the steel, reducing the contact area and preventing burrs or blunt edges on the steel surface from affecting the measurement accuracy.

[0006] Preferably, the measuring blade includes a long measuring blade and a short measuring blade, wherein the length of the long measuring blade is greater than that of the short measuring blade.

[0007] Preferably, the long measuring blade includes a strong magnet A, a non-magnetic body A, and a blade tip A. The non-magnetic body A is disposed between the strong magnet A and the blade tip A. The non-magnetic body A is used to prevent the blade tip A from attracting rust due to its magnetic force, which would cause measurement errors. The strong magnet A and the non-magnetic body A are both cylindrical structures, and the blade tip A is a frustum structure.

[0008] Preferably, the short measuring blade has the same structure as the long measuring blade, and the short measuring blade includes a strong magnet B, a non-magnetic body B, and a blade tip B.

[0009] Preferably, the length of the long measuring blade is greater than the maximum length of the steel burr or blunt edge.

[0010] The advantages of this utility model compared with the prior art are:

[0011] The auxiliary device for measuring the dimensions of burrs and blunt edges described in this utility model uses a measuring blade that is adsorbed onto the jaws of a vernier caliper. During measurement, the tip of the measuring blade contacts the surface of the steel to be measured. This eliminates the need to grind burrs and blunt edges with a polishing machine or clean and polish them by hand, and also eliminates the need to use an ultrasonic thickness gauge with coupling agent, which would result in hands covered in liquid. This utility model saves time and effort, allows for measurement and recording by a single person, is simple to manufacture, convenient to use, and improves measurement efficiency.

[0016] The present invention will be further described below with reference to specific embodiments.

[0017] However, the description of this utility model is only a structural or even functional description of the embodiments, and the scope of the utility model is not limited by the embodiments described herein.

[0018] For example, multiple embodiments may have various modifications and forms, and it should be understood that the scope of this utility model includes equivalents that can realize the technical concept.

[0019] like Figures 1-3 As shown, this embodiment is achieved through the following technical solution: it includes a vernier caliper, which is provided with a fixed jaw 1 and a movable jaw 4, and a measuring blade is detachably connected to the fixed jaw 1 and the movable jaw 4; the measuring blade is provided with a tip and is magnetic, so that it can be attracted to the jaw of the vernier caliper.

[0020] In this embodiment, the measuring blade includes a long measuring blade 2 and a short measuring blade 3, with the length of the long measuring blade 2 being greater than that of the short measuring blade 3. The length of the long measuring blade 2 is 12 mm, and the length of the short measuring blade 3 is 8 mm. The long measuring blade 2 includes a strong magnet A21, a non-magnetic body A22, and a blade tip A23. The non-magnetic body A22 is disposed between the strong magnet A21 and the blade tip A23, and is used to prevent the blade tip A23 from attracting rust due to its magnetic force, which would cause measurement errors. The strong magnet A21 and the non-magnetic body A22 are both cylindrical structures with a cross-sectional diameter of 5 mm, and the blade tip A23 is a frustum structure.

[0021] The short measuring blade 3 has the same structure as the long measuring blade 2. The short measuring blade 3 includes a strong magnet B31, a non-magnetic body B32, and a blade tip B33. The length of the long measuring blade 2 is greater than the maximum length of the steel burr or blunt edge. The blade tips A23 and B33 are made of hard material to improve wear resistance and ensure service life.

[0022] The method of using this utility model is as follows:

[0023] During measurement, attach one measuring blade to each of the fixed jaw 1 and the movable jaw 4 of the vernier caliper, align the tip A23 of the long measuring blade with the tip B33 of the short measuring blade, and record the initial value as a; then use the tips of the two measuring blades to measure the dimension with the burr-blunt edge as b, and ba will give the true measured dimension.
