Description

Technical Field

[0001] The utility model relates to the technical field of positioning jigs, and particularly relates to a positioning jig for detecting the strength of biomimetic materials. Background Technique

[0002] Biomaterials are a class of natural or synthetic special functional materials used to contact and interact with living systems, and can diagnose, treat, replace, repair or induce regeneration of their cells, tissues and organs. They are also called biomedical materials.

[0003] Artificial bones, dentures, etc. are generally more widely used in the field of surgical implantation. Before producing them into artificial bones and dentures, it is necessary to detect the strength of biomaterials. Generally, an influencing positioning jig is required to clamp and limit the biomaterials, and then corresponding strength detection equipment is used to detect their strength. When detecting their strength, a hydraulic device is generally used to extrude them. During the extrusion process, the biomimetic materials may break, which may cause high-speed splashing of impurities, thus causing harm to the safety of the staff.

[0004] Therefore, a positioning jig for detecting the strength of biomimetic materials is proposed. Content of the Utility Model

[0024] Such as Figures 1-4As shown in the figure, a positioning fixture for detecting the strength of biomimetic materials includes a base 1. A cavity 101 is provided in the base 1. A positioning frame 3 is arranged at the top of the base 1. A positioning groove 301 is provided at the top of the positioning frame 3. A placement table 6 is slidably arranged inside the positioning groove 301. A biomimetic material body 5 is placed on the top of the placement table 6. A driving member 7 for driving the placement table 6 to lift is arranged in the cavity 101. The driving member 7 includes a motor 704 arranged at the bottom end inside the cavity 101 and a threaded sleeve 701 rotatably arranged at the bottom end inside the cavity 101. A clamping member 4 for clamping and limiting the biomimetic material body 5 is arranged on the positioning frame 3. The clamping member 4 includes two mounting brackets 401 arranged on the corresponding two sides of the positioning frame 3. A first electric telescopic rod 402 is arranged on one side of the mounting bracket 401. The telescopic end of the first electric telescopic rod 402 is connected to a first connecting plate 403. A second connecting plate 404 is arranged on one side of the first connecting plate 403. A second electric telescopic rod 405 is arranged at the bottom end of the second connecting plate 404. The telescopic end of the second electric telescopic rod 405 is connected to a pressure sensor 406. The bottom end of the pressure sensor 406 is connected to a clamping and limiting plate 407. Specifically, the biomimetic material body 5 is placed on the placement table 6. Then, the clamping member 4 can be used to clamp and position the biomimetic material body 5. Then, the fixture is placed under the strength detection device to extrude the material, so as to test its strength. During the test, since the biomimetic material body 5 is placed inside the positioning groove 301 and the positioning frame 3 can surround the biomimetic material body 5 on all sides, when the biomimetic material body 5 is damaged during measurement, the residue will not splash around and cause harm to the staff, which can play a good protective role. At the same time, after the detection is completed, the arranged driving member 7 can drive the placement table 6 to rise, so as to eject the detected biomimetic material body 5 outwards, which is convenient for taking it. At the same time, the placement table 6 will rise to the same height as the top surface of the positioning frame 3, so it is convenient to clear the residue that falls during the extrusion detection from the inside of the positioning groove 301, and avoid the residue remaining on the surface of the placement table 6 and affecting the detection of the next batch of biomimetic material bodies 5.

[0025] As Figure 2 shown, a chute 4011 is provided at the top of the mounting bracket 401. A first slider 4031 adapted to the chute 4011 is arranged at the bottom end of the first connecting plate 403. Specifically, the chute 4011 can limit the first slider 4031, making the movement of the first connecting plate 403 more stable.

[0026] As Figure 2As shown in the figure, a relief groove is provided on each of the corresponding two sides of the positioning frame 3, and the first connecting plate 403 is adapted to the relief groove; specifically, when clamping and limiting the biological material-like body 5, it can be placed in the positioning groove 301, and then the first electric telescopic rod 402 extends to push the first connecting plate 403 to move. The first connecting plate 403 is moved to the position of the relief groove, and then the second electric telescopic rod 405 extends to push the clamping and limiting plate 407 to move downward, so as to squeeze and limit the biological material-like body 5. During the downward extrusion process, the pressure value detected by the pressure sensor 406 continuously increases. When the pressure value reaches the set value, the second electric telescopic rod 405 will stop extending. At this time, the biological material-like body 5 can be squeezed with a suitable force. The pressure sensor 406 is a prior art and is electrically connected to the controller 2, so the principle, structure and model thereof will not be elaborated here.

[0027] As Figure 3 shown in the figure, the surface of the placement table 6 is made of a material with high hardness; specifically, when performing a strength extrusion test on the biological material-like body 5, the surface of the placement table 6 needs to bear a large force, and its surface hardness is high, and it will not be damaged to a large extent during the detection process.

[0028] As Figure 3 shown in the figure, a threaded rod 702 is connected to the internal thread of the threaded sleeve 701, the threaded rod 702 is connected to the placement table 6, a first gear 703 is sleeved on the threaded sleeve 701, and the main shaft end of the motor 704 is connected to a second gear 705 that meshes with the first gear 703; specifically, when the motor 704 works, it can drive the second gear 705 to rotate. Since the second gear 705 meshes with the first gear 703, it can drive the threaded sleeve 701 to rotate, so as to realize the lifting of the placement table 6.

[0029] As Figure 4 shown in the figure, a limiting member 8 for limiting the placement table 6 is provided in the cavity 101. The limiting member 8 includes two slide rails 801 provided on the corresponding two sides inside the cavity 101. A second slider 802 is slidably provided inside the slide rail 801. A connecting block 803 is provided on one side of the second slider 802. A touch sensor 804 and a connecting rod 805 are provided at the top of the connecting block 803. The connecting rod 805 is connected to the placement table 6; specifically, the second slider 802 slides inside the slide rail 801, so the connecting rod 805 can play a role in limiting the placement table 6. When the placement table 6 rises, it can also drive the connecting block 803 to rise. When the touch sensor 804 touches the top of the base 1, the motor 704 will be controlled to stop working. At this time, the height of the placement table 6 is flush with the height of the positioning frame 3, which is convenient for cleaning the surface of the placement table 6.

[0030] In summary: Place the bio-mimetic material body 5 on the placement tabletop 6. Then, the clamping member 4 can be used to clamp and position the bio-mimetic material body 5. After that, place the fixture under the strength detection device to extrude the material, so as to test its strength. During the test, since the bio-mimetic material body 5 is placed inside the positioning groove 301 and the positioning frame 3 can surround the bio-mimetic material body 5 on all sides, when measuring, when the bio-mimetic material body 5 is damaged, the residue will not splash out in all directions to cause harm to the staff, which can play a good protective role. At the same time, after the detection is completed, the set driving member 7 can drive the placement tabletop 6 to rise, so as to eject the bio-mimetic material body 5 after detection outward, which is convenient for taking it. At the same time, the placement tabletop 6 will rise to the same height as the top surface of the positioning frame 3, so it is convenient to clear the residue that falls during the extrusion detection from the inside of the positioning groove 301 outward, avoiding the residue remaining on the surface of the placement tabletop 6 and affecting the detection of the next batch of bio-mimetic material bodies 5.
