A protective cover is fixedly installed on the outer side of the buffer mechanism. When a side pendulum and an impact hammer perform an impact resistance test on the stainless steel or polypropylene material, if the material is damaged, the side pendulum and the impact hammer will continue to swing forward due to inertia, and then a buffer plate that extends out will prevent the two from swinging forward, thereby reducing the inertial residual force of the side pendulum and the impact hammer to a minimum.

Description

Technical Field

[0001] The invention relates to the technical field of cantilever beam impact testing machines, in particular to a cantilever beam impact testing machine for raw materials used in battery tank production. Background Art

[0002] The Izod impact tester is a device used to measure the impact toughness of non-metallic materials. It is one of the most commonly used impact testers on the market. This device is primarily used to measure the impact toughness of non-metallic materials such as rigid plastics, reinforced nylon, fiberglass, ceramics, cast stone, and electrical insulation. It is an ideal tester for the chemical industry, scientific research institutions, and quality inspection departments at universities and colleges.

[0003] For existing cantilever beam impact testing machines used for battery container raw materials, under normal circumstances, the impact hammer and mechanical transmission components should work together. However, during the operation of the impact hammer, the mechanical transmission components are not inspected in advance. If problems such as bearing wear, belt looseness or poor gear meshing occur, these problems will interfere with the movement of the impact hammer, thereby ensuring that the impact energy can be accurately transmitted to the specimen.

The center of the slip ring 55 is extruded and adapted with a No. 1 bearing 56. The center of the No. 1 bearing 56 is extruded and adapted with an embedded rod 57. The outer side of the embedded rod 57 is fixedly connected to a spline block 58. The end of the spline block 58 close to the fixed disk 53 is fixedly connected to an extension bar 59. By starting the drive component 1, the roller 52 rotates with the fixed disk 53, wherein the roller 52 and the fixed disk 53 are There is a spline groove 54 inside, and the internal sliding adapter of the spline groove 54 is equipped with a slip ring 55, and the interior of the slip ring 55 is connected to the embedded rod 57 through a No. 1 bearing 56, and the engaging block 50 fixedly connected to the outer side of the fixed disk 53 is not engaged with the extension bar 59. Therefore, the entire roller 52 will idle at this time, thereby playing a role in checking in advance whether there are rotation problems and noises in the rotation of the roller 52. The end of the extension bar 59 away from the spline block 58 is provided with a engaging block 50, and the engaging block 50 is fixedly connected to the outer side of the fixed disk 53. The bottom of the spline block 58 is fixedly connected to the connecting sleeve 501, and the bottom of the connecting sleeve 501 is fixedly connected to the impact rod 502, and the bottom of the impact rod 502 is installed with an impact assembly 503. Then close the drive assembly 1 and ask the operator to press the spline block 58 inward. At this time, the spline block 58 will move toward the direction of the roller 52 with the embedded rod 57 and the extension bar 59 respectively. Then the extension bar 59 will be inserted into the engaging block 50 and engage with it, and the embedded rod 57 will extend into the interior of the fixed disk 53 and the spline groove 54 respectively. At this time, start the drive assembly 1 again, so that the fixed disk 53 will rotate with the engaging block 50, and the engaging block 50 will rotate with the extension bar 59 and the spline block 58, so that the connecting sleeve 501 fixedly connected to the bottom of the spline block 58 will swing with the impact rod 502.

[0049] The impact assembly 503 includes a block 531, the top of the block 531 is fixedly connected to the impact rod 502, the bottom of the block 531 is fixedly connected to the impact hammer 532, both ends of the impact hammer 532 are symmetrically connected to vertical rails 533, the internal sliding adaptation of the vertical rail 533 is equipped with a shift plate 534, the bottom of the shift plate 534 is fixedly connected to a side pendulum 535, the inner end face of the shift plate 534 is fixedly connected to an inner slide bar 536, the inner slide bar 536 is slidably adapted inside the impact hammer 532, the top of the inner slide bar 536 is fixedly connected to an electric push rod 537, and the electric push rod 537 is sleeved on the top of the impact hammer 532. The bottom of the impact rod 502 is connected to the impact hammer 532 through the block 531, so the impact hammer 532 will rotate with the vertical rails 533 fixedly connected to its two sides, wherein the interior of the vertical rail 533 is slidably adapted to be fitted with a shift plate 534, and the bottom of the shift plate 534 is connected to the side pendulum 535, so the side pendulum 535 and the impact hammer 532 will swing at the same time, thereby performing impact resistance detection on the top and both ends of the stainless steel or polypropylene material. In addition, the electric push rod 537 can be started, so that the inner slide 536 connected to its bottom end will move upward with the shift plate 534, and the side pendulum 535 connected to the shift plate 534 will move upward. At this time, there are two situations. One is to make the bottom of the side pendulum 535 level with the bottom of the impact hammer 532, so that the two are combined into one to perform a separate anti-stamping test on the top of the material; the other is to move the side pendulum 535 upward for a certain distance, but not to make it level with the bottom of the impact hammer 532. The purpose of this is to adapt the side pendulum 535 to the height of the material to be stamped.

[0050] like Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 and Figure 14 As shown, the clamping mechanism 6 includes a base 61, the bottom of the base 61 is fixedly installed on the bottom of the inner cavity of the protective cover 2, the top of the base 61 is fixedly connected to a plate 62, the top of the plate 62 is fixedly connected to a slide 63 and a support plate 64, wherein the slide 63 and the support plate 64 are connected to each other, the top of the support plate 64 is fixedly connected to a No. 2 limit seat 67, the top of the slide 63 is fixedly installed with a No. 1 limit seat 65, the top of the slide 63 is slidably adapted with a clamping platform 66, the inside of the clamping platform 66 is fixedly connected to a connecting rod 69, the end of the connecting rod 69 away from the No. 2 limit seat 67 is rotatably connected to a threaded rod 68, and the threaded rod 68 is threadedly connected to the inside of the No. 1 limit seat 65.

[0051] The outer side of the threaded rod 68 is extruded and adapted with the No. 2 bearing 60, and the outer side of the No. 2 bearing 60 is extruded and adapted with a bearing sleeve 601. The inner side of the bearing sleeve 601 is fixedly connected with an insertion rod 602, which is inserted into the interior of the No. 1 limit seat 65 and extends to its outside. The threaded rod 68 is fixed with a rotating handle 603 at one end away from the No. 1 limit seat 65. By placing stainless steel or polypropylene material between the clamping table 66 and the No. 2 limit seat 67, the operator then rotates the rotating handle 603 forward, causing the threaded rod 68 connected thereto to spirally advance along the inner wall of the No. 1 limit seat 65, and the other end of the threaded rod 68 is rotatably connected to the connecting rod 69, so the connecting rod 69 will carry the clamp connected to it. The holding platform 66 moves forward along the slide 63 until the clamping platform 66 clamps the stainless steel or polypropylene material. The end of the rotating handle 603 away from the threaded rod 68 is sleeved with a magnetic blocking plate 604, and the interior of the rotating handle 603 is fixedly connected to a partition plate 605, and the inner side of the partition plate 605 is fixedly connected to a No. 1 magnet 606, and the end of the No. 1 magnet 606 away from the partition plate 605 is provided with a partition ring 607, and the end of the partition ring 607 away from the No. 1 magnet 606 is fixedly connected to a spring 608, and the end of the spring 608 away from the partition ring 607 is fixedly connected to an extension handle 609, and the extension handle 609 is inserted into the interior of the rotating handle 603, and the end of the extension handle 609 close to the spring 608 is fixedly connected to the No. 2 magnet 600. In addition, when it is necessary to strengthen the clamping force of stainless steel or polypropylene materials, the magnetic resistance plate 604 is manually pressed, causing the magnetic resistance plate 604 to be inserted into the interior of the rotating handle 603. At this time, the No. 1 magnet 606 and the No. 2 magnet 600 set inside the rotating handle 603 will be blocked by the magnetic resistance plate 604, and the two magnets maintain an attractive relationship. With the obstruction of magnetic attraction, the extension handle 609 connected to the No. 2 magnet 600 will extend outward from the rotating handle 603 under the tensile force of the spring 608. At this time, the operator can rotate the extension handle 609 to increase the torque to strengthen the clamping force of the stainless steel or polypropylene material. In addition, the magnetic resistance plate 604 is pulled out, and the extension handle 609 will be quickly retracted to achieve rapid retraction and release without affecting the operating space.

[0052] The end of the insertion rod 602 away from the bearing sleeve 601 is fixedly connected to the trapezoidal plate 6001, and the trapezoidal plate 6001 is slidably adapted inside the clamping table 66. The end of the trapezoidal plate 6001 away from the insertion rod 602 is squeezed and adapted with an inclined panel 6002, and the end of the inclined panel 6002 away from the trapezoidal plate 6001 is fixedly connected to a bent bar 6003, and the end of the bent bar 6003 away from the inclined panel 6002 is fixedly connected to a sliding plate 6004. The outer side of the sliding plate 6004 is fixedly connected to a return spring 6005, and the end of the return spring 6005 away from the sliding plate 6004 is fixedly connected to a side rail 6006. The side rail 6006 is fixedly connected to the top of the plate 62, and the inside of the side rail 6006 is slidably connected to the sliding plate 6004. As the threaded rod 68 moves toward the position of the second limit seat 67, the bearing sleeve 601 connected to the outer side of the bearing 60 through the second bearing 60 will move accordingly. However, the bearing sleeve 601 is fixedly connected to the insertion rod 602, so the insertion rod 602 will pass through the first limit seat 65 and move inward with the trapezoidal plate 6001 connected to the other end thereof, wherein the trapezoidal plate 6001 is slidably adapted inside the clamping table 66, so as the trapezoidal plate 6001 moves inward, it will squeeze the inclined plate 6002, wherein the trapezoidal plate 6001 The contact surface between 001 and the inclined plate 6002 is an inclined surface, and the squeezed inclined plate 6002 will carry the sliding plate 6004 connected to it by the curved strip 6003 toward the center. The sliding plate 6004 moves toward the center along the side rail 6006 and stretches the return spring 6005. The return spring 6005 also plays a role in resetting the sliding plate 6004. At this time, the sliding plate 6004 will squeeze the two ends of the stainless steel or polypropylene material back into place and then limit it. In addition, the clamping platform 66 and the sliding plate 6004 are synchronized to squeeze and limit the material, and there is no interference between the clamping platform 66 and the sliding plate 6004. The width of the sliding plate 6004 is within the minimum width range of the required inspection material.

[0053] When the present invention is in use: first, the stainless steel or polypropylene material is placed between the clamping platform 66 and the No. 2 limit seat 67, and then the operator rotates the rotating handle 603 in the forward direction, causing the threaded rod 68 connected thereto to spirally advance along the inner wall of the No. 1 limit seat 65, wherein the other end of the threaded rod 68 is rotatably connected to the connecting rod 69, so the connecting rod 69 will carry the clamping platform 66 connected thereto and move forward along the slide 63 until the clamping platform 66 clamps the stainless steel or polypropylene material. In addition, when it is necessary to strengthen the clamping force of stainless steel or polypropylene materials, the magnetic resistance plate 604 is manually pressed, causing the magnetic resistance plate 604 to be inserted into the interior of the rotating handle 603. At this time, the No. 1 magnet 606 and the No. 2 magnet 600 set inside the rotating handle 603 will be blocked by the magnetic resistance plate 604, and the two magnets maintain an attractive relationship. With the obstruction of magnetic attraction, the extension handle 609 connected to the No. 2 magnet 600 will extend outward from the rotating handle 603 under the tensile force of the spring 608. At this time, the operator can rotate the extension handle 609 to strengthen the clamping force of the stainless steel or polypropylene material.

[0054] As the threaded rod 68 moves toward the position of the second limit seat 67, the bearing sleeve 601 connected to it on the outside through the second bearing 60 will move accordingly. However, the bearing sleeve 601 is fixedly connected to the insertion rod 602, so the insertion rod 602 will pass through the No. 1 limit seat 65 and move inward with the trapezoidal plate 6001 connected to its other end. The trapezoidal plate 6001 is slidably adapted inside the clamping platform 66. Therefore, as the trapezoidal plate 6001 moves inward, it will squeeze the inclined plate 6002, and the squeezed inclined plate 6002 will move toward the center with the sliding plate 6004 connected to it through the bent bar 6003. The sliding plate 6004 moves toward the center along the side rail 6006 and stretches the return spring 6005. At this time, the sliding plate 6004 will squeeze the two ends of the stainless steel or polypropylene material back into place and then limit it.

[0055] By starting the driving component 1, the roller 52 rotates with the fixed disk 53, wherein the roller 52 and the fixed disk 53 are both provided with a spline groove 54, and the spline groove 54 is internally adapted for sliding with a slip ring 55, and the interior of the slip ring 55 is connected to the embedded rod 57 through a No. 1 bearing 56, and the engaging block 50 fixedly connected to the outer side of the fixed disk 53 is not engaged with the extension bar 59, so the entire roller 52 will idle at this time to check in advance whether there are any rotation problems or noises in the rotation of the roller 52. Then close the drive assembly 1 and ask the operator to press the spline block 58 inward. At this time, the spline block 58 will move toward the direction of the roller 52 with the embedded rod 57 and the extension bar 59 respectively. Then the extension bar 59 will be inserted into the engaging block 50 and engage with it, and the embedded rod 57 will extend into the interior of the fixed disk 53 and the spline groove 54 respectively. At this time, start the drive assembly 1 again, so that the fixed disk 53 will rotate with the engaging block 50, and the engaging block 50 will rotate with the extension bar 59 and the spline block 58, so that the connecting sleeve 501 fixedly connected to the bottom of the spline block 58 will swing with the impact rod 502. The bottom of the impact rod 502 is connected to the impact hammer 532 via a block 531, so the impact hammer 532 will rotate with the vertical rails 533 fixed to its two sides. The vertical rails 533 are slidably adapted to accommodate a shift plate 534, and the bottom of the shift plate 534 is connected to a side pendulum 535. Therefore, the side pendulum 535 and the impact hammer 532 will swing simultaneously, and the top and both ends of the stainless steel or polypropylene material will be tested for impact resistance. In addition, the electric push rod 537 can be activated, causing the inner slide 536 connected to the bottom end thereof to move the shift plate 534 upward, and the side pendulum 535 connected to the shift plate 534 will also move upward.

[0056] By starting the hydraulic rod 45, the sleeve 44 connected to its telescopic end will move toward the protective cover 2, and then the folding plate 47 connected to the other side of the sleeve 44 through the damper 46 will also move inward. The folding plate 47 is also connected to the inner slide rod 42 and the reducing rod 48 respectively, and the other ends of the inner slide rod 42 and the reducing rod 48 are connected to the buffer plate 43, so the buffer plate 43 will move toward the center of the protective cover 2. Therefore, when the side pendulum 535 and the impact hammer 532 perform impact resistance testing on stainless steel or polypropylene materials, if the material is damaged, the side pendulum 535 and the impact hammer 532 will continue to swing forward due to inertia, and then the extended buffer plate 43 will prevent the two from swinging forward.

[0057] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Various changes made by ordinary technicians in this field based on the above concepts without creative work fall within the scope of protection of the present invention.
