Referring to fig. 1, 2 and 3, a marking distance auxiliary device according to an embodiment of the present invention is used for assisting in marking a sample with a mark separated by a rated distance, including a first marking member 100, a second marking member 200, a workbench 300 and a base 400, the first marking member 100 includes a first connecting portion 110 and a first marking portion 120, the lower end of the first connecting portion 110 is connected to the upper end of the first marking portion 120, the first marking portion 120 is used for marking the sample with the first mark, the second marking member 200 includes a second connecting portion 210 and a second marking portion 220, the lower end of the second connecting portion 210 is connected to the upper end of the second marking portion 220, the second marking portion 220 is used for marking the sample with the second mark, the upper end of the first connecting portion 110 is connected to the lower end of the workbench 300, the upper end of the second connecting portion 210 is connected to the lower end of the workbench 300, the first marking portion 120 and the second marking portion 220 are separated by the rated distance, the upper end of the workbench 300 is used for receiving an external force to make the workbench 300 descend, thereby driving the first marking portion 120 and the second marking portion 220 to descend, the movable workbench 300, and the base 400 is used for supporting the sample 400.

The base 400 is a basic carrier for installing and fixing the parts of the device, is a conceptual object, can be any object, and plays a role in fixing and supporting, for example, an object formed by combining one or more parts such as a metal table, a stone table, a wood table, a support plate, a support frame, a bearing seat, an installation plate, reinforcing ribs, hooks, the ground and the like. In this embodiment, the base 400 is a body, and various supports are disposed at the upper end of the body, and are used for supporting the sample and connecting the working platform 300.

The marking part is used for pressing (stamping) a mark on the surface of the sample, so the lower end of the marking part is relatively sharp. When the actual marking distance is marked, the first marking part 120 marks a first mark on the sample, and the second marking part 220 marks a second mark on the sample, wherein the first mark and the second mark are separated by a rated distance, namely the marking distance; it should be particularly appreciated that after the first mark and the second mark have been marked, the test specimen or the gauge length assistance device may be moved so that the first marker 120 is aligned with the second mark so that the second marker 220 can mark a new mark on the test specimen to mark more gauge length. It should be understood that the upper end of the connecting portion may be connected to the lower end of the workbench 300, and the upper end of the connecting portion may also be connected to the whole workbench 300. After the connecting portion is connected to the table 300, the first marking portion 120 and the second marking portion 220 are separated by a nominal distance, and in particular, a portion marked by the first marking portion 120 (generally, a lower end of the first marking portion 120) is separated by a nominal distance from a portion marked by the second marking portion 220 (generally, a lower end of the second marking portion 220). It should be understood that the nominal distance is a gauge distance, and is generally specifically set according to the actual room temperature tensile test condition of the metal material, for example, in the present embodiment, 25mm may be set. It should be understood that more marking elements may be attached to the table 300, thereby marking more marks at one time.

The connection between the work table 300 and the connection portion may be a fixed connection manner such as welding or integral molding, or a movable connection manner such as screw connection or snap connection. It should be understood that, in the present embodiment, two bolt through holes with parallel axes are provided on the working platform 300 for respectively screwing the first connecting portion 110 and the second connecting portion 210, so the distance between the two bolt through holes is also the rated distance; in other embodiments, the axes of the two bolt through holes intersect, so that the distance between the first marking part 120 and the second marking part 220 can be adjusted by adjusting the length of the threaded connection between the connecting part and the bolt through hole, thereby adjusting the distance between the marked marks (the nominal distance). The first marking member 100 and the second marking member 200 are connected to the worktable 300, and it is required to ensure that when the worktable 300 descends, the first marking part 120 and the second marking part 220 substantially simultaneously contact the surface of the test sample and mark the distance; that is, it is required to ensure that the first marking part 120 and the second marking part 220 have a rated height difference (generally, the height difference is set to be zero). The upper end of the working platform 300 is used for receiving external force, and the external force may be from the force of the working personnel, such as the person pressing and hammering the upper end face of the working platform 300, and the external force may also be from other mechanical devices, such as a cylinder pushing the working platform 300 to slide down. The working platform 300 is movably connected to the base 400, specifically, the working platform 300 may be rotatably connected to the base 400 as in this embodiment, the working platform 300 may also be slidably connected to the base 400 (for example, the base 400 is provided with a slide rail or a slide rod, the working platform 300 is provided with a slide rail or a slide hole), or the working platform 300 may be movably connected to the base 400 by other means.

When the marking distance auxiliary device of the embodiment is used for marking the marking distance (the first marking part 100 and the second marking part 200 are both connected to the workbench 300 in advance, and the height difference between the first marking part 120 and the second marking part 220 is adjusted), the workbench 300 is rotated firstly, so that the workbench 300 and the first marking part 100 and the second marking part 200 connected to the workbench 300 are far away from the base 400 (the arc-shaped groove 421), and a space for placing a sample is left; next, the sample is placed on the base 400 (in the arc-shaped slot 421 of the holding bracket); then, the worktable 300 is rotated reversely, so that the first marking part 120 and the second marking part 220 are close to and abut against the surface of the sample; then, the worker lightly strikes the upper end surface of the workbench 300 through the hammer to make the first marking part 120 and the second marking part 220 mark the first mark and the second mark; finally, referring to the above steps, after the table 300 is turned away, the sample may be moved so that the first marking portion 120 is aligned with the second mark, and then the marking distance operation may be performed again to form a third mark; the formation of more marks is the same.

Referring to fig. 1, 2 and 3, in some embodiments of the present invention, the upper end of the first connection part 110 is threadedly connected with the table 300.

Referring to the above related contents, the upper end of the first connecting portion 110 is screwed to the table 300, so that the height difference between the first marking portion 120 and the second marking portion 220 can be adjusted, and the first marking portion 120 and the second marking portion 220 are generally located on the same horizontal plane, thereby facilitating marking; in some special cases, for example, the sample is in a circular truncated cone shape, the position of the first marking part 120 relative to the second marking part 220 needs to be additionally adjusted (the height difference is not zero), and the specific adjustment result needs to be suitable for the specific shape of the part of the sample needing to be marked with the marking distance.

Referring to fig. 1, 2 and 3, in some embodiments of the present invention, the upper end of the second connection portion 210 is threadedly connected to the table 300.

Referring to the above, the upper end of the second connecting portion 210 is in threaded connection with the workbench 300, so that the range of height difference adjustment is wider, the applicability is better, and the worker can conveniently select and adjust the height difference; more importantly, the marking part is easy to damage, so that the two marking parts are detachably connected with the workbench 300, and the replacement is convenient.

Referring to fig. 1, 2 and 3, in some embodiments of the present invention, the first marking portion 120 is conical with its tip facing downward, and the second marking portion 220 is conical with its tip facing downward.

With reference to the above related contents, the arrangement is such that not only the height difference between the first marking part 120 and the second marking part 220 is adjustable, but also the distance (rated distance) between the first marking part 120 and the second marking part 220 is also adjustable, and the applicability is better.

Referring to fig. 1, 2 and 3, in some embodiments of the present invention, the base 400 further includes a connecting member 510 and a rotating rod 520, the rotating rod 520 is rotatably connected to the rotating bracket 410, one end of the connecting member 510 is fixedly connected to the rotating rod 520, and the other end of the connecting member 510 is fixedly connected to the worktable 300.

The coupling member 510 is provided mainly to allow a certain distance (rotation radius) between the table 300 and the rotation center thereof. In this embodiment, two rotating brackets 410 are provided, one end of the rotating rod 520 is connected to one rotating bracket 410, and the other end of the rotating rod 520 is connected to the other rotating bracket 410. The rotating rod 520 is rotatably connected with the rotating bracket 410, so that the rotating rod 520 can rotate relative to the rotating bracket 410; one end of the connecting member 510 is fixedly connected to the rotating rod 520, and the other end of the connecting member 510 is fixedly connected to the worktable 300, so that the worktable 300 can rotate relative to the rotating bracket 410. The mode of rotating the connection makes the workbench 300 rise and fall relative to the base 400, and the rotating connection is compared with the sliding connection, so that the workbench is not easy to block and runs more smoothly.

Referring to fig. 1, 2 and 3, in some embodiments of the present invention, the base 400 further includes a connecting member 510 and a rotating rod 520, the rotating rod 520 is connected (rotatably connected or fixedly connected) to the rotating bracket 410, one end of the connecting member 510 is rotatably connected to the rotating rod 520, and the other end of the connecting member 510 is fixedly connected to the worktable 300.

The coupling member 510 is provided mainly to allow a certain distance (radius of rotation) between the work table 300 and its rotation center. One end of the connecting member 510 is rotatably connected to the rotating rod 520, and the other end of the connecting member 510 is fixedly connected to the worktable 300, so that the worktable 300 can rotate relative to the rotating rod 520 and the rotating bracket 410. The mode of rotating the connection makes workstation 300 can rise, descend relative base 400, and rotate the connection and compare sliding connection, is difficult to the card and dies, moves more smoothly.

Referring to fig. 1, 2 and 3, in some embodiments of the invention, the base 400 is provided with a support structure 420, the support structure 420 being disposed below the table 300, the support structure 420 serving to support and position the sample.

A holding structure 420 is provided so that the specimen can be positioned on the base 400 without the specimen moving freely during the marking distance. It is understood that the support structure 420 may be part of the base 400, such as a recess formed in the base 400; the support structure 420 may also be a separate accessory, such as a support bracket, which is a structure that is connected (welded, bolted, snap-fit, plug-in, etc.) to the base 400 at the posterior level; other similar structures (rotating bracket 410) are the same.

Referring to figures 1, 2 and 3, in some embodiments of the invention, the support structure 420 is a support cradle, the upper end of which is provided with an arcuate slot 421.

In this embodiment, the portion of the sample to be marked is substantially cylindrical, so that the arc-shaped slot 421 is provided to support and position the sample. Particularly, the sample is generally a bolt, and a bolt head protrudes out of the periphery of the screw rod, so that the bearing bracket is arranged, the whole sample is placed in a suspended manner, and the bolt head cannot abut against the surface of the base 400 to hinder the placement of the bolt.

Referring to fig. 1, 2 and 3, in some embodiments of the present invention, two support brackets are provided, the distance between the two support brackets is smaller than the rated distance, and the two arc-shaped grooves 421 are located between the first marking part 120 and the second marking part 220.

The distance between the two bearing supports is smaller than the rated distance, and the two arc-shaped grooves 421 are both located between the first marking part 120 and the second marking part 220, so that according to the lever principle (or the effect caused by a simple seesaw structure), when the first marking part 120 contacts and applies pressure to the sample, because the force application point of the first marking part 120 to the sample and the force application points of the bearing supports and the sample bearing are not in the force application direction (two points are not in the same vertical line), one end of the sample far away from the first marking part 120 (namely one end contacting the second marking part 220) tends to tilt; similarly, during the marking distance, the end of the sample away from the second marking part 220 (i.e. the end contacting the first marking part 120) also tends to tilt; therefore, when the actual marking distance is marked, if the height difference between the first marking part 120 and the second marking part 220 is not well adjusted according to the specific shape of the sample, the sample can vibrate when the marking distance is marked, even one end of the sample obviously tilts, and at the moment, a worker can timely detect the situation and adjust the height difference in time; if the supporting support is located under the marking part, the tilting tendency and situation cannot be generated, if the height difference is not adjusted, the mark marked by one marking part is too shallow, even the mark is not marked, and workers cannot easily perceive the mark, so that the subsequent metal material room-temperature tensile test is possibly wasted, and the waste of resources and time is caused.

It should be understood that the working table 300 can be moved, so that the first marking part 120 and the second marking part 220 can also be moved, so that only in a specific case, the two arc-shaped slots 421 are strictly located between the first marking part 120 and the second marking part 220; in other cases, it can be said that the two arc-shaped slots 421 are both located in the space between the first marking part 120 and the second marking part 220 (the space has a certain vertical depth).

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
