Description

Technical Field

[0001] This invention relates to the field of strength testing technology, and in particular to a strength testing device for the production of shielded doors. Background Technology

[0002] During the production process of shielded doors, in order to test their ultimate performance, some of their materials (especially non-metallic materials) need to be tested using a falling ball impact tester to verify their local impact resistance.

[0003] Traditional drop ball impact testing machines lack a steel ball reset mechanism. After each test, the operator must manually return the steel ball to the drop bar and adjust it to the preset height. This process increases test preparation time, and especially when multiple tests are required consecutively, manual reset significantly prolongs the test cycle, thereby reducing test efficiency. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a strength testing device for the production of shielded doors.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A strength testing device for the production of shielding doors includes a base plate, a base fixedly installed on one side of the top of the base plate, a guide rail vertically installed on the base, a drop bar movably installed on the guide rail, and a magnetic suction component installed on the drop bar.

[0007] The reinforcing plates are all fixedly installed above the base plate and located on both sides of the base. A female pull rope compartment is fixedly provided on the side of the reinforcing plate closer to the base, and a female pull rope compartment is fixedly provided on the side of the reinforcing plate away from the base.

[0008] The movable rod is located on both sides of the top of the base plate. One side of one end of the movable rod is connected to the sub-traction rope in the sub-traction rope compartment, and the other side is connected to the female traction rope in the female traction rope compartment.

[0009] The counterweight is adapted to move vertically within the sub-traction rope compartment. The top of the counterweight is connected to one end of the sub-traction rope, and the other end of the sub-traction rope is connected to the movable rod.

[0010] The pressure bars are fixedly installed on both sides of the drop bar. The bottom of each pressure bar is provided with a rope pressing component for pressing down the traction rope, and a pressure seat is provided on each pressure bar on the movable bar.

[0011] In addition, a preferred structure is that side plates are fixedly installed upward on all four sides of the base plate, the base is fixedly installed in the middle of the short side of the base plate, and a vertical guide rail is fixedly installed upward on the top of the base.

[0012] In addition, a preferred structure is that a magnetic suction assembly is movably provided on the drop bar, a short baffle is fixedly provided on the side of the magnetic suction assembly away from the guide rail, and a long baffle is fixedly provided on the side of the magnetic suction assembly close to the guide rail.

[0013] In addition, a preferred structure is that the sub-rope chamber is provided with a counterweight cavity and a sub-rope cavity respectively, and multiple guide columns are vertically fixed in the counterweight cavity. The counterweight blocks are all adapted to be located in the counterweight cavity and moved by being guided by the guide columns.

[0014] In addition, a preferred structure is that multiple guide rope rings are fixedly installed in each of the sub-pulling rope cavities, one end of the sub-traction rope is connected to the top of the counterweight, and the other end extends into the sub-pulling rope cavity. After passing through multiple guide rope rings, it extends out of the sub-pulling rope cavity and is connected to the movable rod.

[0015] Furthermore, in a preferred configuration, the interior of the female pull rope compartment is provided with a female pull rope cavity, and multiple guide rope rings are fixedly installed inside the female pull rope cavity. One end of the female traction rope is connected to the inner wall of the female pull rope cavity, and the other end of the female traction rope passes through the guide rope rings and the base in sequence before being connected to the movable rod.

[0016] In addition, a preferred structure is that a rope pressing groove is provided inward on one side of the female rope chamber, the rope pressing groove is connected to the female rope cavity, and the rope pressing groove is adapted to the pressing rod.

[0017] In addition, the preferred structure is that both sides of the base are fixedly vertically arranged with fixed columns, the other end of which is fixedly connected to the pull rope compartment. The movable rod is adapted to have through holes corresponding to the fixed columns, and the movable rod is guided to move or rotate through the fixed columns.

[0018] In addition, in a preferred configuration, a support base is fixedly provided at the bottom of one end of the movable rod on the base plate, and guide members are fixedly provided at both ends of the support base. Guide grooves are adapted to be opened on the movable rod corresponding to the guide members, and multiple spacers are fixedly provided on the support base.

[0019] Furthermore, in a preferred configuration, the side of the movable rod facing away from the base is set as a flat surface, while the side facing the base is set as an inclined surface. Additionally, the end of the movable rod near the through hole is wider, while the end near the guide groove is narrower.

[0020] The beneficial effects of this invention are as follows: by hitting the workpiece with a steel ball, its local impact resistance can be tested and verified. After the steel ball is hit, by controlling the drop bar to move down, the movable bars on both sides can be moved and rotated to reset the steel ball to the magnetic suction assembly. In this way, the steel ball can be automatically reset after each test, which is convenient for users. Attached Figure Description

[0040] 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.

[0041] See Figure 1-2 A base 11 is fixedly mounted on one side of the top of the base plate 1. A guide rail 111 is vertically mounted on the base 11, and a drop bar 12 is movably mounted on the guide rail 111. A magnetic attraction component 13 is movably mounted on the drop bar 12. It is worth noting that the drop bar 12 moves vertically on the guide rail 111 by electric drive, and the magnetic attraction component 13 is an electromagnet, which moves laterally on the drop bar 12 by electric drive. These are all existing technologies, so they will not be described in detail.

[0042] Among them, side plates 15 are fixedly installed on all four sides of the base plate 1. The side plates 15 can prevent the steel ball from falling off due to bouncing when it falls, thus ensuring that the steel ball will not pop out of the base plate 1.

[0043] A short baffle 131 is fixedly installed on the side of the magnetic attraction component 13 away from the guide rail 111, and a long baffle 132 is fixedly installed on the side of the magnetic attraction component 13 closer to the guide rail 111. The short baffle 131 protects the magnetic attraction component 13 from damage by the rolling steel ball. The long baffle 132 blocks the steel ball from escaping the attraction range of the magnetic attraction component 13.

[0044] The drop bar 12 has pressure bars 121 fixedly installed on both sides, and each pressure bar 121 has a rope pressing component 122 at its bottom. When the drop bar 12 moves downward, the rope pressing component 122 can press the main traction rope 41 downward to achieve the traction movement of the movable bar 5. Furthermore, the pressure bars 121 can press the pressure seat 53 downward to achieve the rotation of the movable bar 5.

[0045] See Figure 3-7 A reinforcing plate 2 is fixedly installed on both sides of the base plate 11. A female pull rope compartment 4 is fixedly installed on the side of the reinforcing plate 2 closest to the base 11, and a female pull rope compartment 3 is fixedly installed on the side of the reinforcing plate 2 away from the base 11. The reinforcing plates 2 can strengthen the support of the guide rail 111 to ensure the stability of the guide rail 111.

[0046] Both sides of the base 11 are fixedly vertically mounted with fixing posts 14, and the other end of each fixing post 14 is fixedly connected to the pull rope compartment 3. The movable rod 5 has corresponding through holes 54 on each fixing post 14, and the fixing posts 14 pass through the through holes 54. The fixing posts 14 not only guide one end of the movable rod 5 to improve its stability during movement, but also allow the movable rod 5 to rotate around the fixing posts 14. This allows the pressure rod 121 to lift the other end of the movable rod 5 upwards when pressing down on the pressure seat 53.

[0047] See Figure 6-13 The pull rope compartment 3 has a counterweight cavity 301 and a pull rope cavity 302. Multiple guide posts 33 are vertically fixed within the counterweight cavity 301. The counterweight blocks 32 are all adapted to be located within the counterweight cavity 301 and moved by the guide posts 33. The guide posts 33 improve the stability of the counterweight blocks 32 during movement. It is worth noting that the movable rod 5 is made of lightweight material and has a hollow internal structure; therefore, the weight of each counterweight block 32 is greater than the weight of the movable rod 5. This allows the counterweight blocks 32 to pull the pull rope 31 during resetting, thereby resetting the movable rod 5.

[0048] Each of the sub-pulling rope cavities 302 has multiple guide rope rings 21 fixedly installed inside. One end of the sub-traction rope 31 is connected to the top of the counterweight 32, and the other end extends into the sub-pulling rope cavity 302. After passing through the multiple guide rope rings 21, it extends out of the sub-pulling rope cavity 302 and connects to the movable rod 5. The guide rope rings 21 in the sub-pulling rope cavity 302 guide the sub-traction rope 31 to ensure that it does not get tangled during movement.

[0049] The female pull rope compartment 4 has a female pull rope cavity 401 inside, and multiple guide rope rings 21 are fixedly installed inside the female pull rope cavity 401. One end of the female traction rope 41 is connected to the inner wall of the female pull rope cavity 401, and the other end of the female traction rope 41 passes through the guide rope rings 21 and the base 11 in sequence before being connected to the movable rod 5. The guide rope rings 21 in the female pull rope cavity 401 can guide the female traction rope 41 to ensure that the female traction rope 41 does not get tangled when it is moving.

[0050] It is worth noting that both the secondary traction rope 31 and the tertiary traction rope 41 are wear-resistant ropes to ensure their service life and traction strength. Furthermore, both the secondary traction rope 31 and the tertiary traction rope 41 are connected to the internal skeleton of the movable rod 5 to ensure the stability of the movable rod 5 when it is pulled. Their specific materials and connection structures are existing technologies and will not be elaborated upon further.

[0051] The female pull rope compartment 4 has a rope-pressing groove 42 on one side, which is connected to the female pull rope cavity 401 and is adapted to the pressing rod 121. When the pressing rod 121 moves downward, both the pressing rod 121 and the rope-pressing component 122 can pass through the rope-pressing groove 42. This allows the rope-pressing component 122 to press down on the female traction rope 41, causing it to bend. Since one end of the female traction rope 41 is fixedly connected to the inner wall of the female pull rope cavity 401, the other end of the female traction rope 41 can automatically retract, thereby pulling the movable rod 5. At this time, the movable rods 5 on both sides can move towards the center.

[0052] As the movable rod 5 moves, it can pull the sub-traction rope 31, which can then lift the counterweight 32 from the counterweight cavity 301.

[0053] When the pressure rod 121 moves upward, the main traction rope 41 no longer pulls on the movable rod 5, and the counterweight 32 can then fall automatically under gravity. During the fall of the counterweight 32, it can pull the secondary traction rope 31, which in turn pulls the movable rod 5 to reset. As the movable rod 5 resets, the main traction rope 41 also gradually and synchronously resets.

[0054] See Figure 14-18 A support base 6 is fixedly installed on the bottom of the base plate 1 at the other end of the movable rod 5. Guide members 61 are fixedly installed at both ends of the support base 6. Guide grooves 55 are adapted to the guide members 61 on the movable rod 5. Multiple spacers 62 are fixedly installed on the support base 6.

[0055] One end of the movable rod 5 is guided to move by the fixed column 14, and the other end is guided to move by the guide member 61, which improves the stability of the movable rod 5 during movement. Furthermore, the guide members 61 on the support base 6 are only provided at both ends of the support base 6 to avoid interference with the movable rod 5 when it is tilted.

[0056] The side of the movable rod 5 facing away from the base 11 is set as a flat surface 51, and the side facing the base 11 is set as a slope 52. The end of the movable rod 5 near the through hole 54 is wider, and the end near the guide groove 55 is narrower.

[0057] The inclined surface 52 not only slopes upwards from the bottom, but also slopes from the end near the through hole 54 to the end near the guide groove 55. This makes the width of the movable rod 5 greater at the end near the through hole 54 and smaller at the end near the guide groove 55. This allows the movable rods 5 on both sides to push the steel ball towards the support seat 6 when they move towards the center, even though they are only translating.

[0058] The spacer 62 can block the tilted movable rod 5, preventing it from moving to either side. When the movable rod 5 falls, the guide groove 55 on the movable rod 5 aligns with the guide member 61, and the spacer 62 can no longer block the movable rod 5, allowing it to move normally.

[0059] In this embodiment, when the user needs to test the workpiece, they simply place the workpiece on the base plate 1 and position it using the positioning fixture on the base plate 1. Then, the user can control the drop bar 12 and the magnetic suction assembly 13 to move to the designated position, and then de-energize the magnetic suction assembly 13. At this point, the steel ball on the magnetic suction assembly 13 will automatically fall and strike the workpiece to test and verify its local impact resistance.

[0060] After the steel ball falls, the drop bar 12 can be controlled to move downwards, causing the pressure bar 121 and the rope pressure component 122 to move downwards synchronously. As the rope pressure component 122 moves, it extends into the rope pressure groove 42 and bends and presses down the female traction rope 41. Since one end of the female traction rope 41 is fixedly connected to the inner wall of the female pull rope cavity 401, the other end of the female traction rope 41 can automatically retract to pull the movable rod 5. At this time, the movable rods 5 on both sides can move towards the middle.

[0061] This allows the steel ball to be pushed towards the center of the workpiece by moving the movable rods 5 on both sides. Furthermore, the inclined surface 52 on the movable rods 5 allows the steel ball to be pushed towards the center and simultaneously towards the support base 6.

[0062] Furthermore, as the movable rod 5 moves, it can pull the sub-traction rope 31, thereby pulling the counterweight 32 upward through the sub-traction rope 31.

[0063] As the movable rod 5 moves, when the guide groove 55 on the movable rod 5 separates from the guide member 61, the pressure rod 121 and the pressure seat 53 make adaptive contact. At this time, as the pressure rod 121 moves downward, the pressure seat 53 can be pressed down, thereby lifting the other end of the movable rod 5. It is worth noting that, through the principle of leverage, the pressure rod 121 only needs to move down a small portion to lift the movable rod 5. Furthermore, both the sub-traction rope 31 and the female traction rope 41 are close to the fixed post 14, so when the movable rod 5 is lifted, the sub-traction rope 31 and the female traction rope 41 will not move significantly. Moreover, the positions of the sub-traction rope 31 and the female traction rope 41 are reserved in the design process, so the lifting of the movable rod 5 will not affect the sub-traction rope 31 and the female traction rope 41.

[0064] As the movable rod 5 moves, the steel ball is pushed to its tilted end by the inclined plane 52. Therefore, when the movable rod 5 is tilted, the steel ball is also tilted synchronously, and the steel ball can then automatically roll towards the magnetic assembly 13 by gravity. Since the steel balls are of different sizes, there are two possible scenarios.

[0065] When the steel ball is large, the lifted steel ball rolls toward the magnetic attraction component 13 via the movable rod 5. The short baffle 131 can block the steel ball to prevent it from damaging the magnetic attraction component 13.

[0066] Then, the drop lever 12 and the magnetic suction assembly 13 are moved upwards. As the magnetic suction assembly 13 moves upwards, the angle at which the movable lever 5 is tilted gradually decreases. At this time, the distance between the short baffle 131 and the movable lever 5 gradually increases, allowing the steel ball to pass through the short baffle 131. Subsequently, the steel ball is blocked by the long baffle 132 and cannot move. However, at this time, the steel ball is located at the bottom of the magnetic suction assembly 13. At this point, the magnetic suction assembly 13 is energized, and the magnetic force generated by the magnetic suction assembly 13 can be used to attract the steel ball, thereby achieving the repositioning of the steel ball.

[0067] When the steel ball is small, the tilted steel ball rolls towards the magnetic attraction component 13 via the movable rod 5. At this time, the steel ball can pass directly through the bottom of the short baffle 131 and is then blocked by the long baffle 132. At this point, the magnetic attraction component 13 is directly energized, and the magnetic attraction force generated by the magnetic attraction component 13 can be used to attract the steel ball and thus reset the steel ball.

[0068] It is worth noting that the smallest steel ball is also larger than the maximum distance between the two movable rods 5, so as to ensure that the steel ball can be lifted when the two movable rods 5 move towards the center and rotate.

[0069] Furthermore, after the steel ball is attracted and reset by the magnetic attraction component 13, the drop bar 12 can be controlled to move upward and reset, thereby driving the pressure bars 121 and the pressure rope component 122 on both sides to move upward synchronously.

[0070] As the pressure rod 121 moves upward, it no longer presses down on the pressure seat 53. At this point, the movable rod 5, which had been lifted, can automatically return to its original position by gravity. Furthermore, the guide groove 55 on the movable rod 5 is once again aligned with the guide member 61.

[0071] Subsequently, as the rope-pressing component 122 moves upward, it no longer presses down and bends the female traction rope 41, thus the female traction rope 41 no longer pulls the movable rod 5. At this time, the counterweight 32 can automatically fall under its own weight, thereby pulling the secondary traction rope 31, which in turn pulls the movable rod 5 to its reset position.

[0072] During the resetting process of movable rod 5, it can pull the female traction rope 41 to straighten and reset it, thereby achieving the synchronous resetting of the male traction rope 31, the female traction rope 41, and movable rod 5. At this time, the movable rods 5 on both sides can be reset to the side plate 15 again, and the steel ball is also retrieved onto the magnetic suction assembly 13. The user can then remove the workpiece and observe and evaluate its condition to assess its local impact resistance. After the evaluation is completed, the next workpiece can be tested.

[0073] Furthermore, one end of the movable rod 5 is guided to move by the fixed column 14, and the other end is guided to move by the guide member 61, so the bottom of the movable rod 5 does not contact the base plate 1. This allows the user to install positioning fixtures on the base plate 1 to position the workpiece and ensure that after positioning, the top surface of the workpiece is aligned with the bottom surface of the movable rod 5, so as to avoid the workpiece affecting the movement of the movable rod 5.

[0074] It is worth noting that the positioning fixture is existing technology. It is laid flat on top of the base plate 1 and its dimensions are adapted to the base plate 1. When the positioning fixture positions the workpiece, the top of the workpiece is aligned with the top of the positioning fixture, and a level pad can be installed on the outer side of the workpiece. This ensures that the steel ball will not get stuck due to the height difference between the workpiece and the positioning fixture when it moves and resets, so that the movable rods 5 on both sides can stably push the steel ball. Furthermore, the positioning fixture can be replaced with an automatic type to improve the automation level of this device. These are all existing technologies and are not the main technical problems to be solved in this invention, so they will not be described in detail.

[0075] Therefore, in this application, after the steel ball falls, simply controlling the drop lever 12 to move downwards will move the secondary traction rope 31 and the tertiary traction rope 41, thereby pulling the movable rod 5 to move. In conjunction with the pressure rod 121, the movable rod 5 will be lifted, thus achieving automatic reset of the steel ball. Then, simply controlling the drop lever 12 to move upwards to reset will automatically reset the secondary traction rope 31, the tertiary traction rope 41, and the movable rod 5 via the counterweight 32.

[0076] This structure not only enables automatic reset of the steel ball, reducing user operation steps, but also allows operation to be performed solely by the movement of the drop lever 12, eliminating the need for additional actuators and sensor components, resulting in lower costs compared to existing technologies.

[0077] In this invention, the local impact resistance of a workpiece can be tested and verified by throwing a steel ball at it. After the steel ball is thrown, the drop bar 12 is controlled to move downward, which can drive the movable bars 5 on both sides to move and rotate, so as to reset the steel ball to the magnetic suction assembly 13. In this way, the steel ball can be automatically reset after each test, which is convenient for users.

[0078] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
