[0025] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0031] The terms used in this document generally have the ordinary meaning of each term used in this field, in the context of the case and in the specific context, unless otherwise noted. Certain terms used to describe the present invention will be discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art in describing the present invention.
[0032] The terms "front", "back", "up", "down", "left", "right", etc. used in this article are all directional terms. In this case, they are only used to illustrate the positional relationship between the various structures, and are not used to limit the protection plan of this case and the specific direction during actual implementation.
[0033] See attached Figure 1~Figure 4 As shown, a bar length measuring device provided in this embodiment includes a positioning seat 1 and a measuring caliper 2.
[0034] A limiting groove 11 is provided on the positioning seat 1 for limiting the radial displacement or rolling of the rod 3, and the limiting groove 11 has an extension direction corresponding to the length direction of the rod 3 to ensure that the limiting groove 11 can bear the entire structure of the rod 3 and limit the rod 3.
[0035] The measuring caliper 2 includes a main scale 23, a first end 21 and a second end 22 of the main scale 23 are fixedly arranged at both ends of the positioning seat 1, and the main scale 23 is parallel to the limiting groove 11 on the positioning seat 1. Since the extension direction of the limiting groove 11 corresponds to the length direction of the bar 3, it can be understood that the main scale 23 is parallel to the bar 3 located on the limiting groove 11, thereby ensuring the parallelism between the main scale 23 and the bar 3, and further ensuring the accuracy of measuring the bar 3; and, due to the fixed setting of the measuring caliper 2, the stability of the measuring caliper 2 relative to the positioning seat 1 during the measurement process can also be guaranteed, and because the limiting groove 11 opened on the positioning seat 1 can limit the displacement of the bar 3 to ensure the stability of the bar 3 relative to the positioning seat 1, the stability of the measuring caliper 2 relative to the bar 3 during the measurement process can be achieved, further improving the accuracy of measuring the bar 3.
[0036] Optionally, the limiting groove 11 is a V-shaped groove, and the two side surfaces of the V-shaped groove serve as limiting surfaces for limiting the bar material 3 to be tested.
[0037] like Figure 5 As shown, when the same V-shaped groove limits the position of two bars 3 to be tested with different diameters, the two limiting surfaces of the V-shaped groove contact the two bars 3 to be tested at different positions, which will affect the limiting effect on the bars 3 to be tested with different diameters. For example, there are a first bar 31 with a smaller diameter value and a second bar 32 with a larger diameter value. When a V-shaped groove with a set notch width limits the first bar 31, the V-shaped groove can limit the first bar 31 through the two limiting surfaces. When the same V-shaped groove limits the second bar 32, the V-shaped groove only limits the second bar 32 through two edges, and most of the structure of the second bar 32 itself is located outside the V-shaped groove. In comparison, it is obvious that the V-shaped groove has a better limiting effect on the first bar 31.
[0038] In order to solve the problem of measurement stability of the above-mentioned different diameters of the bar materials 3 to be tested, it is preferred that the number of the limit grooves 11 is at least two, at least two limit grooves 11 are arranged in parallel and spaced apart along the first direction, and the slot widths of each limit groove 11 are different. The limit grooves 11 with different slot widths can be suitable for limiting the bar materials 3 to be tested with different diameters, thereby improving the versatility of the bar length measuring device; wherein the first direction corresponds to the radial direction of the bar material 3.
[0039] In this embodiment, the number of the limiting grooves 11 is two.
[0040] Considering that there is hard contact between the rod and the limiting surface of the limiting groove 11, friction may occur when the two are in contact. Preferably, the inner surface of the limiting groove 11 is provided with a protective layer (not shown in the figure), which extends along the length direction of the limiting groove 11. Optionally, the protective layer is a cemented carbide layer.
[0041] The main scale 23 is also provided with two measuring claws, which can be divided into a fixed claw 24 and a movable claw 25 according to their respective movement forms during the measurement process. The fixed claw 24 is fixedly set at the first end of the main scale 23, and the movable claw 25 is slidably set on the main scale 23; during the measurement process, the movable claw 25 slides on the main scale 23, and makes the fixed claw 24 and the movable claw 25 respectively fit the two ends of the bar 3 to be measured to replicate the length of the bar 3 to be measured, and then the length is displayed on the main scale 23.
[0042] Optionally, the measuring caliper is a vernier digital caliper, which can directly display the length of the measured bar 3 after the measurement is completed, so that the operator can read the length value of the bar 3 conveniently.
[0043] In order to further achieve the purpose of accurately and quickly measuring the bar 3 to be measured, in this embodiment, an elastic member (not shown in the figure) is provided between the moving claw 25 and the fixed claw 24, or between the moving claw 25 and the second end 22 of the main scale 23. The elastic member can prompt the moving claw 25 to always maintain a tendency to move toward the fixed claw 24, and then the moving claw 25 can use the elastic member to quickly and firmly clamp the bar 3 located in the limiting groove 11 for accurate measurement.
[0044] In one embodiment, a spring is provided between the moving claw 26 and the second end 22 of the main scale 23 .
[0045] In another embodiment, a tension spring is provided between the movable claw 26 and the fixed claw 24 .
[0046] The working process of the existing utility model is as follows:
[0047] The positioning seat 1 has a limiting groove 11 for limiting the displacement of the bar material. The number of the limiting grooves 11 is at least two, and the slot widths of at least two limiting grooves 11 are different, so as to adapt to the bars 3 to be tested with different diameter values and provide a better limiting effect for the bars 3 to be tested. The operator selects a suitable limiting groove 11 according to the diameter of the bar material 3 to be tested, and places the bar material 3 to be tested in the corresponding limiting groove 11;
[0048] A protective layer is provided in the limiting groove 11 to prevent the bar from directly contacting the inner surface of the V-shaped groove and causing friction;
[0049] After the bar 3 to be measured is stabilized in the limit groove 11, under the action of the elastic member (spring or tension spring), the movable claw 26 of the measuring caliper 2 always maintains a tendency to move toward the fixed claw 24, that is, the operator does not need to manually move the movable claw 26 of the measuring caliper 2 to measure the length of the bar 3 to be measured. The movement tendency of the movable claw 26 itself enables it to automatically approach and contact the bar 3 to be measured, so as to quickly and firmly clamp the bar 3 located in the limit groove 11, thereby achieving the purpose of fast and accurate measurement, saving time and manpower.
[0050] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
