Description

Technical Field

[0001] The utility model relates to the technical field of metal material detection, in particular to a device for detecting the tensile resistance of metal materials. Background Technique

[0002] In the production process of metal materials, it is necessary to detect the tensile resistance of the produced metal materials to judge their quality performance in subsequent production and use. When detecting the tensile resistance of metal materials, the positions at both ends of the metal materials are clamped and stretched, and various data during the stretching of the metal materials are recorded, so as to complete the detection of the metal materials.

[0003] In a device for detecting the tensile resistance of metal materials disclosed in the Chinese Utility Model Patent Application Publication Specification CN218646743U, when the servo motor rotates, it can drive one of the detection seats to move, and then perform the tensile resistance detection on the metal materials. The operation is relatively convenient and has good tensile strength. The two ends of the metal materials are fixed by the limiting component, which can ensure the stability of the metal materials during the tensile resistance detection. However, the overall applicability of the device for detecting the tensile resistance of metal materials is relatively low, and the position of the clamping component is fixed and not easy to replace. For metal materials of different specifications, the clamping stability may be relatively low, thus affecting the subsequent clamping detection effect. Content of the Utility Model

[0004] The purpose of the utility model is to provide a device for detecting the tensile resistance of metal materials to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A device for detecting the tensile resistance of metal materials, including a detection table, a first disassembly mechanism is arranged on one side of the top of the detection table, a first clamping seat is arranged on the top of the first disassembly mechanism, a clamping mechanism is arranged on one side of the first clamping seat, a moving mechanism is arranged on one side of the inner part of the detection table, a second disassembly mechanism is arranged on one side of the moving mechanism, a second clamping seat is installed on the top of the second disassembly mechanism, a limiting mechanism is arranged on one side of the second disassembly mechanism, sliding mechanisms are arranged on both sides of the top of the detection table, a protective cover is arranged on the top of the sliding mechanisms, and a laser rangefinder is installed at the bottom of one side inside the protective cover.

[0007] Preferably, the clamping mechanism includes fixing plates fixedly connected to both ends on one side of the first clamping seat. A bolt is threadedly connected to the middle position inside the fixing plate. One side of the winding roller is rotatably connected with a clamping plate.

[0008] Preferably, the moving mechanism includes a servo motor installed on one side inside the detection table. A threaded rod is installed at the output shaft end of the servo motor. A threaded block, with one side fixedly connected to the second disassembly mechanism, is threadedly connected to the outside of the threaded rod.

[0009] Preferably, the limiting mechanism includes a sliding rod fixedly connected to one side inside the detection table. A slider, with one side fixedly connected to the second disassembly mechanism, is slidably connected to one side of the outside of the sliding rod.

By rotating the rotating rod on the first clamping seat, the rotating rod drives the winding roller to rotate, enabling the winding roller to pull the first movable plate on one side of the clamping block through the pull rope, so that the clamping block is withdrawn from the inside of the card slot, completing the replacement of the first clamping seat. At the same time, the replacement of the second clamping seat at the top of the second disassembly mechanism can be quickly carried out, thereby quickly adjusting the clamping mechanism according to different metal materials that need to be tensile tested, improving the overall applicability of the metal material detection device;

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0020] Please refer to Figures 1-4, the present utility model provides two technical solutions:

[0021] Embodiment 1

[0022] A device for detecting the tensile property of a metal material, comprising a detection table 1. On one side of the top of the detection table 1, a first disassembly mechanism 2 is provided. On the top of the first disassembly mechanism 2, a first clamping seat 3 is provided. On one side of the first clamping seat 3, a clamping mechanism 4 is provided. On one side of the interior of the detection table 1, a moving mechanism 5 is provided. On one side of the moving mechanism 5, a second disassembly mechanism 6 is provided. On the top of the second disassembly mechanism 6, a second clamping seat 601 is installed. On one side of the second disassembly mechanism 6, a limiting mechanism 7 is provided. On both sides of the top of the detection table 1, a sliding mechanism 8 is provided. On the top of the sliding mechanism 8, a protective cover 9 is provided. At the bottom of one side inside the protective cover 9, a laser rangefinder 10 is installed. The connection mode of the second disassembly mechanism 6 and the second clamping seat 601 at the top is the same as the connection mode of the detection table 1 and the first clamping seat 3, so that the second clamping seat 601 can be quickly disassembled and replaced. The protective cover 9 is made of reinforced explosion-proof glass. At the same time, a laser rangefinder 10 is installed on one side inside the protective cover 9. The laser rangefinder 10 is respectively provided with a laser emitter and a photoelectric element. A laser beam is emitted by the laser, and after the laser beam irradiates the surface of the metal specimen, it is received by the photoelectric element. By measuring the time difference or the change in angle of the reflected beam, the distance from the beam to the metal surface is calculated. When a force or strain is applied, the position of the metal surface changes slightly, and by measuring this change, the strain of the metal specimen can be obtained, so that engineers can accurately evaluate the tensile characteristics of the metal material under different stress conditions.

[0023] The first disassembly mechanism 2 includes a slot 101 arranged at the middle position on one side of the top end of the detection table 1. On both sides inside the slot 101, there are clamping grooves 102. An insertion block 201 is inserted into the inside of the slot 101. On both sides of the insertion block 201, there are sliding-connected clamping blocks 202 that are inserted into the clamping grooves 102. On one side of the clamping block 202, there is fixedly connected a first movable plate 203. On one side of the first movable plate 203, there is fixedly connected a first spring 204. At the middle position inside the top end of the first clamping seat 3, there is a rotatably connected rotating rod 301. At the bottom end of the rotating rod 301, there is fixedly connected a winding roller 302 that rotates inside the insertion block 201. On both sides of the winding roller 302, there are fixedly connected pulling ropes 303 that are fixedly connected to the first movable plate 203. When the clamping blocks 202 on both sides of the insertion block 201 receive a force from bottom to top, the first spring 204 can be squeezed through the first movable plate 203. At this time, the clamping blocks 202 can be retracted into the inside of the insertion block 201. Due to the reaction force of the squeezed first spring 204, when the clamping blocks 202 are not stressed, the clamping blocks 202 can be pushed out of the inside of the insertion block 201 through the first movable plate 203. At the same time, when the rotating rod 301 at the top end of the first clamping seat 3 rotates, the winding roller 302 can be driven to pull the pulling ropes 303 on both sides to wind. At this time, the pulling ropes 303 can pull the clamping blocks 202 to move through the first movable plate 203.

[0024] The clamping mechanism 4 includes fixing plates 401 fixedly connected to both ends on one side of the first clamping seat 3. At the middle position inside the fixing plates 401, there is a screw-connected bolt 402. On one side of the winding roller 302, there is a rotatably connected clamping plate 403. When the bolt 402 on the fixing plate 401 is rotated, the bolt 402 can push the clamping plate 403 to move. At this time, the two clamping plates 403 can perform the clamping and limiting work on one end of the metal material.

[0025] The moving mechanism 5 includes a servo motor 501 installed on one side inside the detection table 1. At the output shaft end of the servo motor 501, there is installed a threaded rod 502. Outside the threaded rod 502, there is a threaded block 503 whose one side is fixedly connected to the second disassembly mechanism 6. When the servo motor 501 is started, it can drive the threaded rod 502 to rotate. At this time, the threaded block 503 on the threaded rod 502 can freely move on the threaded rod 502 and drive the second disassembly mechanism 6 and the second clamping seat 601 to move.

[0026] The limiting mechanism 7 includes a sliding rod 701 fixedly connected to one side inside the detection table 1. On one side outside the sliding rod 701, there is a sliding-connected slider 702 whose one side is fixedly connected to the second disassembly mechanism 6. When the second disassembly mechanism 6 moves, it can drive the slider 702 to slide on the sliding rod 701.

[0027] Embodiment 2

[0028] The main difference from Embodiment 1 is that:

[0029] A device for detecting the tensile property of a metal material. In the sliding mechanism 8, it includes sliding grooves 801 arranged on both sides inside the top end of the detection table 1. On one side inside the sliding grooves 801, auxiliary blocks 802 are evenly arranged at equal distances. On one side of the auxiliary blocks 802, a second movable block 803 is fixedly connected. On one side of the second movable block 803, a second spring 804 is fixedly connected. On both sides of the bottom end of the protective cover 9, sliding plates 901 inserted into the sliding grooves 801 are fixedly connected. On one side of the sliding plates 901, positioning grooves 902 inserted into the auxiliary blocks 802 are evenly arranged at equal distances. Inside the bottom end of the sliding plates 901, balls 903 are slidably connected. When the auxiliary blocks 802 are stressed, the auxiliary blocks 802 can squeeze the second movable block 803. At this time, the auxiliary blocks 802 can be retracted into the detection table 1 and inserted into the sliding grooves 801 through the sliding plates 901 at the bottom end of the protective cover 9. At the same time, the auxiliary blocks 802 in the sliding grooves 801 are clamped into the positioning grooves 902 on the sliding plates 901, then the position fixation of the protective cover 9 at the top end of the detection table 1 can be completed. At the same time, balls 903 are arranged at the bottom end of the sliding plates 901, which can reduce the friction generated when the sliding plates 901 move in the sliding grooves 801. At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0030] When the embodiment of the present application is in use: The moving mechanism 5 drives the second clamping seat 601 at the top end of the second disassembly mechanism 6 to move to a position suitable for the size of the metal material. By rotating the bolts 402 on the first clamping seat 3 and the second clamping seat 601, at this time, the bolts 402 can rotate in the fixing plate 401 to push the clamping plates 403 to move, and the two groups of clamping plates 403 on the first clamping seat 3 and the second clamping seat 601 complete the clamping work on both ends of the metal material. At this time, the protective cover 9 can be covered outside the stretching part of the metal material. Then, the moving mechanism 5 drives the second disassembly mechanism 6 and the second clamping seat 601 to move to the right side of the detection table 1, then the tensile detection work of the metal material can be carried out. At the same time, the laser rangefinder 10 in the protective cover 9 emits a laser beam by using a laser. After the laser beam irradiates the surface of the metal specimen, it is received by a photoelectric element. By measuring the time difference or angle change of the reflected beam, the distance from the beam to the metal surface is calculated, so as to detect the external strain of the metal material.
