[0002] A tensile testing machine, also known as a universal testing machine, is a mechanically applied testing machine used to perform static load, tensile, compression, bending, shearing, tearing, and peeling tests on various materials. The tensile testing machine fixture is an important component of the instrument and is a crucial factor in whether the test can be carried out smoothly and the accuracy of the test results.

[0003] For example, Chinese patent application No. 202122466197.6 discloses a tensile testing machine fixture, including a mounting frame. Both sides of the mounting frame have screw holes, and a screw rod is threaded into the screw holes. One end of the screw rod is rotatably connected to a clamping block, and the clamping block has a toothed groove on the side away from the screw rod. A lead screw is fixed to the top of the inner side of the mounting frame, and a nut is threaded onto the surface of the lead screw. A clamping cap, which is conical, is fixed to the bottom of the nut. A through hole is formed in the middle of the lead screw, and a baffle is fixed to the bottom end of the lead screw. A rotating groove is formed on one side of the clamping block, and a connecting block is rotatably connected inside the rotating groove. One side of the connecting block is fixed to the screw rod.

[0004] However, the following problems still exist in this technical solution: In some tensile tests, the clamping mechanism cannot be well protected when the clamps are not used. In the event of a collision, the clamping mechanism is easily damaged, making the device unusable. Utility Model Content

[0005] The purpose of this utility model is to provide a tensile testing machine clamp that can protect the clamping plate through a protective mechanism to prevent the clamping plate from being damaged by collision, thereby extending the service life of this utility model. It also has a disassembly mechanism that allows the clamping plate to be replaced so as to clamp different materials and improve practicality, thereby solving the above-mentioned shortcomings in the technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tensile testing machine clamp, including a mounting column installed on the tensile testing machine, two clamping plates at the bottom of the mounting column, a protective mechanism for protecting the clamping plates on the outside of the mounting column, a clamping mechanism for moving the two clamping plates at the bottom of the mounting column, and a third bolt threaded to the top of the mounting column.

[0007] Preferably, the protection mechanism includes a protective cover disposed outside the mounting column. A first placement groove is provided inside the mounting column. A threaded rod is movably connected inside the first placement groove via a bearing. A connecting plate is threadedly connected to the outside of the threaded rod. The two sides of the connecting plate pass through the mounting column and extend out of the two sides of the mounting column. The two sides of the connecting plate extending out of the two sides of the mounting column are fixedly connected to the top of the protective cover to protect the clamping plate.

[0008] Preferably, the mounting column has a second placement groove inside, the top end of the threaded rod passes through the first placement groove and extends into the second placement groove, and a first motor is fixedly installed at the top end of the threaded rod to drive the threaded rod to rotate.

Limiting grooves are fixed on both sides of the top of the sealing plate. The plug-in plates are adapted to the limiting grooves. Support plates are fixed on both sides of the top of the sealing plate. First threaded holes are provided on both sides of the protective cover and on the support plates. Multiple connected first threaded holes are internally threaded with the same first bolt for sealing the protective cover.

[0010] Preferably, the clamping mechanism includes a control box located at the bottom of the mounting column. Inside the control box, a bidirectional threaded rod is movably connected via bearings. Both ends of the bidirectional threaded rod are threadedly connected to limit plates. The bottom of the limit plates passes through the control box and extends out of the bottom of the control box. The clamping plate is located at the bottom of the limit plates and is used to drive the two clamping plates to move.

[0011] Preferably, a rotating shaft is movably connected to the top of the control box via a bearing. The top of the rotating shaft passes through the control box and extends into the mounting column. The rotating shaft and the mounting column are movably connected via a bearing.

[0031] like Figure 4 As shown, the clamping mechanism 4 includes a control box 401 located at the bottom of the mounting column 1. A bidirectional threaded rod 402 is movably connected inside the control box 401 via a bearing. Both ends of the bidirectional threaded rod 402 are threadedly connected to a limiting plate 403. The bottom of the limiting plate 403 passes through the control box 401 and extends out of the bottom of the control box 401. The clamping plate 2 is located at the bottom of the limiting plate 403.

[0032] like Figure 4 As shown, a rotating shaft 404 is movably connected to the top of the control box 401 via a bearing. The top of the rotating shaft 404 passes through the control box 401 and extends into the mounting column 1. The rotating shaft 404 and the mounting column 1 are movably connected via a bearing. A second motor 406 is fixedly mounted on the top of the rotating shaft 404. A bevel gear 405 passes through both the bottom of the rotating shaft 404 and the outside of the bidirectional threaded rod 402. The two bevel gears 405 mesh with each other.

[0033] The mounting column 1 can be installed on the tensile testing machine by means of the third bolt 6. Start the second motor 406, which can drive the rotating shaft 404 to rotate. The rotating shaft 404 can drive the bidirectional threaded rod 402 to rotate by means of the two bevel gears 405. The rotation of the bidirectional threaded rod 402 can drive the limiting plate 403 to move. The limiting plate 403 can drive the clamping plate 2 to move. The clamping plate 2 can clamp the material.

[0034] like Figure 3 , 6As shown, the protection mechanism 3 includes a protective cover 301 disposed outside the mounting column 1. A first placement groove 302 is provided inside the mounting column 1. A threaded rod 306 is movably connected inside the first placement groove 302 via a bearing. A connecting plate 303 is threadedly connected to the outside of the threaded rod 306. The two sides of the connecting plate 303 pass through the mounting column 1 and extend out of the two sides of the mounting column 1. The two sides of the connecting plate 303 extending out of the two sides of the mounting column 1 are fixedly connected to the top of the protective cover 301. A second placement groove 304 is provided inside the mounting column 1. The top end of the threaded rod 306 passes through the first placement groove 302 and extends into the second placement groove 304.

The same first bolt 312 is threaded inside the multiple connected first threaded holes 311.

[0036] When not using this invention, the first motor 305 is started, which drives the threaded rod 306 to rotate. The rotation of the threaded rod 306 causes the connecting plate 303 to move. The connecting plate 303 then moves the protective cover 301 downward, enclosing the clamping plate 2 inside the protective cover 301. Then, the plug plate 308 on the sealing plate 307 is inserted into the limiting groove 309. The first bolt 312 is rotated to fix the sealing plate 307 to the bottom of the protective cover 301. This invention can protect the clamping plate 2 through the protection mechanism 3, preventing the clamping plate 2 from being damaged by collision and extending the service life of this invention.

[0038] Rotate the second bolt 505 to pull it out from the second threaded hole 503 and the third threaded hole 504. Then pull the clamping plate 2 to pull the fixing plate 501 on the top of the clamping plate 2 out from the insertion slot 502. This allows the clamping plate 2 to be replaced so that it can clamp different materials and improve its practicality.
