Detailed Implementation

[0041] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0042] like Figure 1-11As shown, this invention provides a tensile testing device and method based on applied physics, including a test chamber 1. The test chamber 1 contains a tensile testing cavity 15. A tensile testing mechanism is provided on the end wall of the tensile testing cavity 15. The tensile testing mechanism is used to perform tensile tests on the test piece. The tensile testing mechanism includes an electrically telescopic rotating shaft 24 symmetrically rotatably connected to the end wall of the tensile testing cavity 15. A gear cavity 16 is machined inside the test chamber 1. A drive gear shaft 19 is rotatably connected between the end walls of the gear cavity 16. The drive gear shaft 19 is poweredly connected to a drive motor 18, and the drive motor 18 is fixedly mounted... Inside the test chamber 1, a drive gear 20 is fixedly mounted on the outer surface of the drive gear shaft 19. The drive gear 20 meshes with the driven gear 17. The driven gear 17 is fixedly mounted on the surface of the electric telescopic shaft 24, which extends into the gear cavity 16. A clamping groove block 25 is fixedly connected to one end of the electric telescopic shaft 24. A rotating cavity 62 is uniformly machined within the clamping groove block 25, and the rotating cavity 62 is arranged along the circumference of the clamping groove block 25. A clamping screw is slidably connected through the end wall of the rotating cavity 62. 53. The clamping screw 53 is threadedly connected to the clamping nut block 64. The clamping nut block 64 is rotatably mounted on the end wall of the rotating cavity 62. The rack ring 63 is fixedly mounted on the outer surface of the rack ring 63. The rack ring 63 meshes with the double-sided annular rack 66. The double-sided annular rack 66 is rotatably mounted in the clamping groove block 25. The clamping groove block 25 is provided with a clamping gear cavity 55. A clamping gear shaft 67 is rotatably connected between the end walls of the clamping gear cavity 55. The clamping gear shaft 67 is poweredly connected to the clamping motor 59. The clamping motor 59 is fixedly mounted in the clamping groove block. Inside 25, a clamping gear 56 is fixedly installed on the outer surface of the clamping gear shaft 67. The clamping gear 56 meshes with the double-sided annular rack 66. A brake tooth 60 is fixedly installed on the outer surface of the clamping gear shaft 67. The brake tooth 60 meshes with a brake tooth 58. The brake tooth 58 is fixedly installed at the end of the brake electric push rod 57. The brake electric push rod 57 is fixedly installed on the end wall of the clamping gear cavity 55. A limiting groove 61 is provided on the clamping screw 53. The limiting groove 61 is slidably connected to the limiting block 65. The limiting block 65 is fixedly installed inside the clamping groove block 25.

[0043] The test piece is placed into the tensile testing chamber 15. Power is supplied to the electric telescopic shaft 24, causing the clamping groove block 25 to move, allowing both ends of the test piece to enter the clamping groove block 25. The clamping motor 59 is activated, causing the clamping gear shaft 67 to rotate, which in turn rotates the clamping gear 56. The clamping gear 56 meshes with the double-sided annular rack 66, causing it to rotate. The double-sided annular rack 66 meshes with the rack ring 63, causing the clamping nut block 64 to rotate. The clamping nut block 64 is threadedly connected to the clamping screw 53, causing it to move and clamp the test piece. The limiting block 65 and the limiting groove 61 work together to ensure that the clamping screw 53 can only slide and cannot rotate. Subsequently, the electric brake push rod 57 is energized, thereby driving the brake tooth 58 to move, causing the brake tooth 58 to mesh with the brake tooth 60, thus braking the clamping gear shaft 67 and increasing the clamping reliability. This causes the electric telescopic shaft 24 to move outward, thereby pulling the clamping groove block 25 to move, thus moving the test piece and stretching it, thus performing a tensile test on the test piece. The drive motor 18 is then activated, causing the two drive motors 18 to move in opposite directions, thereby driving the drive gear shaft 19 to rotate, which in turn drives the drive gear 20 to rotate. The drive gear 20 meshes with the driven gear 17, thereby driving the electric telescopic shaft 24 to rotate, causing the two electric telescopic shafts 24 to rotate in opposite directions, thus performing a torsional test when the test piece is stretched.

[0044] Advantageously, an impact mechanism is provided on the end wall of the tensile testing chamber 15. The impact mechanism impacts the test piece, thereby conducting an impact test on the tensile test piece. The impact mechanism includes an impact groove 43 provided on the end wall of the tensile testing chamber 15. An impact screw 44 is rotatably connected between the end walls of the impact groove 43 and the impact screw 44. The impact screw 44 is poweredly connected to a moving motor, which is fixedly installed inside the test chamber 1. The impact screw 44 is threadedly connected to an impact nut block 45, which is slidably connected to... A mounting bracket 51 is fixedly connected to the end wall of the impact nut block 45 between the end walls of the impact groove 43. A cam cavity 46 is provided inside the mounting bracket 51. A cam shaft 48 is rotatably connected between the end walls of the cam cavity 46. The cam shaft 48 is poweredly connected to the impact motor. The impact motor is fixedly installed in the mounting bracket 51. A cam 47 is fixedly installed on the outer surface of the cam shaft 48. The cam 47 contacts the impact rod 49 and pushes the impact rod 49 to move. A return spring 50 is nested on the outer surface of the impact rod 49.

[0045] The moving motor is then activated, which drives the impact screw 44 to rotate, thereby moving the impact nut block 45 to the corresponding position. The impact motor is then activated, which drives the camshaft 48 to rotate, thereby driving the cam 47 to rotate. The cam 47 pushes the impact rod 49 to move, causing the impact rod 49 to move and contact the surface of the test piece. Due to the action of the return spring 50, the impact rod 49 reciprocates, thereby reciprocatingly impacting the surface of the test piece.

[0046] Advantageously, a freezing mechanism is provided on the end wall of the tensile testing chamber 15. This freezing mechanism is used to freeze the surface of the test piece, allowing for tensile testing under frozen conditions. The freezing mechanism includes a cooling groove 21 on the end wall of the tensile testing chamber 15. A cooling screw 22 is rotatably connected between the end walls of the cooling groove 21. The cooling screw 22 is powered by a freezing motor, which is fixedly installed inside the test chamber 1. A cooling nut block 37 is threaded onto the outer surface of the cooling screw 22 and slidably installed between the end walls of the cooling groove 21. A cooling electric push rod 38 is fixedly connected to the end wall of the nut block 37. A braking arc block 41 is fixedly installed on the end wall of the cooling electric push rod 38 away from the cooling nut block 37. A connecting cavity 40 is provided inside the braking arc block 41. Braking nozzles 42 are evenly fixedly connected to the end wall of the braking arc block 41. The braking nozzles 42 extend into the connecting cavity 40. A gas supply pipe 52 is fixedly connected to the end wall of the connecting cavity 40. The end of the gas supply pipe 52 away from the connecting cavity 40 is fixedly connected to a cooling gas storage box 14. The cooling gas storage box 14 is fixedly installed on the end wall of the test chamber 1.

[0047] This starts the refrigeration motor, which drives the cooling screw 22 to rotate, thereby moving the refrigeration nut block 37 to the corresponding position. This energizes the refrigeration electric push rod 38, causing the braking arc block 41 to move towards the test piece, placing the test piece inside the braking arc block 41. The refrigeration gas in the refrigeration gas storage tank 14 enters the communicating cavity 40 through the gas supply pipe 52. The braking nozzle 42 is then turned on, allowing the refrigeration gas to be sprayed onto the surface of the test piece, thereby cooling the surface of the test piece.

[0048] Advantageously, a heating mechanism is provided on the bottom wall of the tensile testing chamber 15. The heating mechanism is used to heat the surface of the test piece, which facilitates tensile testing under heated conditions. The heating mechanism includes a heating groove 29 provided on the bottom wall of the tensile testing chamber 15. A heating screw 30 is rotatably connected between the end walls of the heating groove 29. The heating screw 30 is poweredly connected to a heating motor 31. The heating motor 31 is fixedly installed in the test chamber 1. A heating nut block 28 is threadedly connected to the outer surface of the heating screw 30. The heating nut block 28 is slidably connected between the end walls of the heating groove 29. A heating electric push rod 27 is fixedly installed on the upper surface of the heating nut block 28. A heating block 26 is fixedly installed at the upper end of the heating electric push rod 27.

[0049] This starts the heating motor 31, which drives the heating lead screw 30 to rotate. The heating lead screw 30 is threadedly connected to the heating nut block 28, which in turn drives the heating electric push rod 27 to move. Powering the heating electric push rod 27 causes the electric telescopic shaft 24 to move, which in turn drives the heating block 26 to move closer to the test piece, thus activating the heating block 26 to heat the test surface.

[0050] Advantageously, the test chamber 1 is provided with a sealing mechanism for sealing the tensile test chamber 15. The sealing mechanism includes symmetrically arranged sealing gear chambers 33 inside the test chamber 1. A sealing gear shaft 36 is rotatably connected between the end walls of the sealing gear chambers 33. The sealing gear shaft 36 is poweredly connected to a sealing motor 35. The sealing motor 35 is fixedly installed inside the test chamber 1. A sealing gear 34 is fixedly installed on the outer surface of the sealing gear shaft 36. The sealing gear 34 meshes with a rack 6. The rack 6 is fixedly installed on the end wall of the groove 9. The groove 9 is located at the lower part of the sealing plate 5. A sliding groove 12 is symmetrically arranged on the upper part of the test chamber 1. A cross 13 is slidably connected between the end walls of the sliding groove 12. The sealing plate 5 is fixedly connected to the upper surface of the cross 13.

[0051] This starts the closed motor 35, which drives the closed gear shaft 36 to rotate, which in turn drives the closed gear 34 to rotate. The closed gear 34 meshes with the rack 6, which in turn drives the closed plate 5 to move, thereby sealing the tensile test chamber 15.

[0052] Advantageously, the test chamber 1 is provided with a fixing mechanism for fixing the test chamber 1. The fixing mechanism includes a fixing plate 11 fixedly connected to the end wall of the test chamber 1, and fixing bolts 10 are connected to the fixing plate 11 to fix the fixing plate 11 to the ground.

[0053] The fixing plate 11 is then fixedly installed on the laboratory floor using the fixing bolts 10, thereby fixing the test chamber 1.

[0054] Advantageously, an observation groove 7 is machined through the closed plate 5, and a glass plate 8 is fixedly installed between the end walls of the observation groove 7;

[0055] Thus, the situation inside the tensile test chamber 15 can be observed through the glass plate 8.

[0056] Advantageously, an operating table 2 is fixedly connected to the end wall of the test chamber 1, an operating panel 3 is fixedly connected to the operating table 2, and a display panel 4 is fixedly connected to the end wall of the operating table 2. The operating panel 3 and the display panel 4 are signal-connected to the control processor. The control processor is fixedly installed inside the operating table 2 and is signal-connected to the electrical components in the device.

[0057] The corresponding operation command is input on the operation panel 3, and the operation panel 3 sends it to the control processor. The control processor sends the corresponding signal to the corresponding electrical component, and the corresponding data information is sent to the display panel 4 through the control processor for display.

[0058] Advantageously, an annular frame 54 is rotatably connected to the end wall of the clamping groove block 25, and telescopic rods 23 are uniformly fixedly connected to the annular frame 54. The end of the telescopic rod 23 away from the annular frame 54 is fixedly connected to the end wall of the tensile test chamber 15. The telescopic rod 23 is arranged along the circumferential direction of the annular frame 54. The annular frame 54 and the closed gear cavity 33 increase the stability of the clamping groove block 25 and ensure stability during tensioning.

[0059] This invention provides a tensile testing method based on applied physics, using the aforementioned tensile testing apparatus based on applied physics, comprising the following steps:

[0060] Step 1: Fix the test chamber 1 on the floor of the test chamber using the fixing mechanism;

[0061] Step 2: Input the corresponding operation command on the operation panel 3, transmit the command to the control processor, the control processor sends a signal to the corresponding component, and the display panel 4 displays the corresponding data;

[0062] Step 3: The closing mechanism moves, thereby opening the tensile test chamber 15. After the tensile test chamber 15 is opened, the test piece is placed into the tensile test chamber 15.

[0063] Step 4: The tensile testing mechanism moves to clamp the test object and perform a tensile test. It can also perform a torsion test during the tensile test, and a combined tensile-torsion test.

[0064] Step 5: Place the test piece into the tensile test chamber 15. After clamping, the closing mechanism moves to close the tensile test chamber 15. Observe the inside of the tensile test chamber 15 through the glass plate 8.

[0065] Step Six: During the test, the impact mechanism moves to perform an impact test on the test piece under tension; the tensile test and the impact test are performed simultaneously.

[0066] Step 7: During the test, the freezing mechanism moves to perform a freezing test on the test piece during the tensile test, which facilitates the tensile test under the condition that the test piece is frozen;

[0067] Step 8: During the test, the heating mechanism moves to heat the test piece during the tensile test, which facilitates the tensile test under heated conditions.

[0068] The working process of this invention involves fixing the fixing plate 11 to the laboratory floor using the fixing bolts 10, thereby fixing the test chamber 1, supplying power to the entire device, inputting corresponding operation commands on the operation panel 3, which then sends them to the control processor. The control processor sends corresponding signals to the corresponding electrical components, and the feedback data is sent to the display panel 4 for display. The test piece is then placed into the tensile testing chamber 15, and the electric telescopic shaft 24 is energized, causing the clamping groove block 25 to move, allowing both ends of the test piece to enter the clamping groove block 25, thus activating the clamping mechanism. Motor 59 drives the clamping gear shaft 67 to rotate, which in turn drives the clamping gear 56 to rotate. The clamping gear 56 meshes with the double-sided annular rack 66, which in turn drives the double-sided annular rack 66 to rotate. The double-sided annular rack 66 meshes with the rack ring 63, which in turn drives the clamping nut block 64 to rotate. The clamping nut block 64 is threadedly connected to the clamping screw 53, which in turn drives the clamping screw 53 to move and clamp the test sample. The limiting block 65 and the limiting groove 61 work together to ensure that the clamping screw 53 can only slide and cannot rotate. After clamping, the enclosed motor 35 is started, which drives the enclosed gear shaft 36 to rotate, which in turn drives the enclosed gear 34 to rotate. The enclosing gear 34 meshes with the rack 6, thereby driving the enclosing plate 5 to move and thus enclosing the tensile test chamber 15. Power is supplied to the brake electric push rod 57, causing the brake tooth 58 to move, thus engaging with the brake tooth 60 and braking the clamping gear shaft 67, increasing the clamping reliability. This causes the electric telescopic shaft 24 to move outward, thereby pulling the clamping groove block 25 to move, thus moving the test piece and subjecting it to tensile stress. The drive motors 18 are activated, causing the two drive motors 18 to move in opposite directions, thereby driving the drive gear shaft 19 to rotate, which in turn drives the drive gear... When wheel 20 rotates, the driving gear 20 meshes with the driven gear 17, thereby driving the electric telescopic shaft 24 to rotate. The two electric telescopic shafts 24 rotate in opposite directions, thus performing a torsional test on the test piece during tensile testing. The moving motor is activated, driving the impact screw 44 to rotate, which in turn moves the impact nut block 45 to the corresponding position. The impact motor is then activated, driving the camshaft 48 to rotate, which in turn drives the cam 47 to rotate. The cam 47 pushes the impact rod 49 to move, causing the impact rod 49 to contact the surface of the test piece. Due to the action of the return spring 50, the impact rod 49 reciprocates, thus reciprocatingly impacting the surface of the test piece.The refrigeration motor is started, which drives the cooling screw 22 to rotate, thereby moving the refrigeration nut block 37 to the corresponding position. The refrigeration electric push rod 38 is energized, causing the braking arc block 41 to move towards the test piece, placing the test piece within the braking arc block 41. Refrigeration gas from the refrigeration gas storage tank 14 enters the communicating cavity 40 through the gas supply pipe 52. The braking nozzle 42 is activated, allowing refrigeration gas to be sprayed onto the surface of the test piece, thus cooling the surface. The heating motor 31 is started, driving the heating screw 30 to rotate. The heating screw 30 is threadedly connected to the heating nut block 28, thereby moving the heating electric push rod 27. The heating electric push rod 27 is energized, causing the electric telescopic shaft 24 to move, thereby moving the heating block 26 closer to the test piece, activating the heating block 26 to heat the test surface.
