Description

Technical Field

[0001] The utility model relates to a measuring tool, in particular to a caliper measuring tool for quickly measuring a high-precision single-specification cylinder. Background Art

[0002] The diameter of conventional cylindrical products is usually measured with a vernier caliper and an outside micrometer. However, the vernier caliper has a large measurement error, and the reading is prone to errors, which is also closely related to the measurement method and habits of the personnel. Although the outside micrometer has high accuracy, it is prone to reading errors in measurement and is not convenient to use.

[0003] At present, with the continuous improvement of living standards, people's requirements for products are getting higher and higher, and correspondingly, customers' requirements for upstream products are also getting higher and higher. Taking the requirements for a cylindrical product as an example, customers gradually increase from conventional national standards to high special specifications and high precision requirements. At the same time, they must ensure the consistency of product dimensions in length and diameter. In addition to high requirements for the production process of the product, higher requirements are also put forward for product measurement. For these high-precision and high-requirement products, it is necessary to measure the dimensions of the products one by one with a wire rod, but the traditional vernier caliper and micrometer measurement of dimensions have great problems in measurement time, measurement error and labor intensity, and the overall efficiency is low and the cost is high.

[0004] Therefore, providing a dimension measuring tool with simple structure, convenience, speed and low price is a technical problem that needs to be solved urgently. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a caliper measuring tool for quickly measuring a high-precision single-specification cylinder.

[0006] In order to achieve the above-mentioned purpose, the utility model designs a caliper measuring tool for quickly measuring high-precision single-specification cylinders, including a caliper body, a first column, a second column, a third column, and a fourth column. The first column and the second column are vertically fixed to the upper edge of the caliper body at a first spacing, the third column and the fourth column are vertically fixed to the lower edge of the caliper body at a second spacing, the second column is marked with the size of the first spacing, and the first spacing is the lower limit of the caliper measuring tool measuring the size of the cylinder, the fourth column is marked with the size of the second spacing, and the second spacing is the upper limit of the caliper measuring tool measuring the size of the cylinder.

[0007] Preferably, ends of the first column, the second column, the third column and the fourth column are all rounded.

[0008] Preferably, the caliper body is rectangular, and one end thereof away from the first column and the third column is rounded.

[0009] Preferably, a circular hole is formed at one end of the caliper body away from the first column and the third column.

[0010] The utility model has the following beneficial effects:

[0011] It avoids the errors caused by a person using a traditional vernier caliper for a long time, shortens the reading time of each measurement, and can quickly measure dimensions within a continuous length range, avoiding the time wasted when using a traditional caliper to measure dimensions every few millimeters. It can also quickly measure the dimensions in the circumferential direction of the same section, avoiding the size deviation of two points in the same diameter direction.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example:

[0019] See also Figure 1-4A caliper measuring tool for quickly measuring a high-precision single-specification cylinder comprises a caliper body 1, a first column 2, a second column 3, a third column 4, and a fourth column 5. The first column 2 and the second column 3 are vertically fixed to the upper edge of the caliper body 1 at a first spacing 6, and the third column 4 and the fourth column 5 are vertically fixed to the lower edge of the caliper body 1 at a second spacing 7. The second column 3 is marked with the size of the first spacing 6, and the first spacing 6 is the lower limit of the caliper measuring tool for measuring the size of the cylinder. The fourth column 5 is marked with the size of the second spacing 7, and the second spacing 7 is the upper limit of the caliper measuring tool for measuring the size of the cylinder. The sizes of the first spacing and the second spacing are marked on the columns, so that the measurement personnel can quickly select the corresponding measuring tool to avoid wrong selection. The height of the first column 2, the second column 3, the third column 4, and the fourth column 5 of this embodiment are all 70 mm, and the width is 20 mm. The height is selected to be 70 mm, mainly considering that the height should be greater than the diameter of the cylinder to be measured, so that the size in the circumferential direction can be measured more accurately. The width is selected to be 20 mm to avoid bending the measuring tool during the measurement process, which affects the accuracy of the measuring tool. The size of the first spacing is 59.82 mm. The size of the second spacing is 60.18 mm. The width of the caliper body 1 is 40 mm.

[0020] As a preferred implementation manner of this embodiment, the ends of the first column 2, the second column 3, the third column 4, and the fourth column 5 are all rounded with a radius of 5 mm. The rounding is firstly for faster insertion into the measured cylinder, and secondly to avoid the sharp corners of the column ends from scratching the measurement personnel. Thirdly, it is considered to avoid the sharp corners of the column ends from scratching the surface of the measured cylinder, causing secondary defects and affecting the surface quality of the product.

[0021] Preferably, the caliper body 1 is rectangular, and one end thereof away from the first column 2 and the third column 3 is rounded. The caliper body 1 is a rectangular parallelepiped, and the rightmost side is the handle area. To avoid scratches, the end is rounded, and the radius of the rounded corner is 5 mm. To facilitate the personnel to hold the caliper body 1, the width is selected to be 40 mm, which is wider than the thumb of the general personnel for easy use. The selected width can ensure that the personnel can hold the caliper handle completely, which is convenient for the personnel to hold and use force.

[0022] A circular hole 8 is formed at one end of the caliper body 1 away from the first column 2 and the third column 3. The diameter of the circular hole 8 is 5 mm, which is convenient for hanging and collecting the caliper body 1 and for carrying when measuring the size in batches to avoid dropping or losing it during the measurement process.

[0023] The best application occasion for the measuring tool of this embodiment is when the customer has very high requirements for the dimensional accuracy of cylindrical products of a certain specification and needs to use a cleaning rod and measure the dimensions of the products one by one.

[0024] The specific operation process is as follows:

[0025] like Figure 2 As shown, when all the cylindrical products enter the first spacing 6, it means that the diameter of the cylindrical products is too small and does not meet the process requirements.

[0026] like Figure 3 As shown, when the cylindrical product cannot completely enter the second spacing 7, it means that the diameter of the cylindrical product is too large and does not meet the process requirements.

[0027] like Figure 4 As shown, when the cylindrical product cannot completely enter the first spacing 6, and the cylindrical product completely enters the second spacing 7, it means that the diameter of the cylindrical product meets the process requirements.

[0028] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
