Description

Technical Field

[0001] This invention relates to the field of impact testing machine technology, specifically to a device and method for testing the mechanical properties of titanium alloy forgings. Background Technology

[0002] Impact testing machines are core equipment for determining the impact resistance of materials. By simulating high-speed impact loads, they can accurately obtain key data such as the impact absorption energy of materials. They are widely used in the field of metal material quality control. In the mechanical property testing of titanium alloy forgings, they are an indispensable key equipment. Titanium alloy forgings are often used in high-end scenarios such as aerospace, and their toughness and impact resistance must be strictly controlled.

[0003] Currently, when existing impact testing machines are in use, the broken test samples cannot be effectively collected after the test is completed, requiring workers to pick them up on the side. In addition, when the test sample fails and breaks into multiple pieces or small fragments, staff also need to clean the debris from the surface of the testing table, which greatly affects the testing progress of the next test sample.

[0004] In light of the above issues, it becomes clear that existing mechanical property testing devices for titanium alloy forgings on the market cannot simultaneously avoid the problems mentioned above. Even if they can solve these problems, they require the assistance of external tools, thus failing to achieve the desired results. Therefore, we propose a mechanical property testing device and method for titanium alloy forgings. Summary of the Invention

Several identical second inductive touch metal buttons are fixedly connected to the front of each partition, and each force-bearing shaft is located in the inner cavity of the return spring.

[0018] A testing method for a mechanical property testing device for titanium alloy forgings includes the following steps:

[0019] S1: When using the recycling unit, first connect all the electric drive structures of the device to the impact testing machine body through wires. After the pendulum is rotated to a suitable height and locked, place the test piece between the two second positioning plates and the first positioning plate. With the support of the rectangular frame, start the second stepper motor. The hexagonal block drives the first fixing bolt to rotate, so that the second positioning plate moves closer to the first positioning plate to clamp the test piece. The rubber on the contact surface of the two can increase the friction, and the first positioning plate retracts into the rectangular frame to ensure that the test piece is subjected to uniform force. Then, the first hydraulic rod drives the sliding frame and the second stepper motor to move, so that the hexagonal block is disengaged from the first fixing bolt. Control the pendulum to fall and impact the test piece. The broken test piece will fall down along with the second positioning plate and the first positioning plate and pull the transmission rope. After the test is completed, start the first stepper motor to rewind the transmission rope and reset the second positioning plate and the first positioning plate. Then, the second stepper motor reverses the operation to move the second positioning plate away from the first positioning plate, thus completing the recovery of the broken part.

[0020] S2: When using the storage unit, the number of fracture segments of the test piece is related to its quality. The fewer the segments, the better the quality. The more segments, the greater the possibility of internal defects such as air bubbles. First, place the collection box behind the second hydraulic rod and align it with the entrance of the long frame. After the recycling unit completes the recycling work, the fractured piece will enter the collection box. When the weight is qualified, the first inductive touch metal button will be triggered. Then, the impact testing machine body controls the second hydraulic rod to push the collection box into the long frame. Through the transmission of several collection boxes inside, the collection box containing the fractured piece is pushed to the side of the third hydraulic rod. If the first inductive touch metal button is triggered, it means that the weight of the fractured piece is qualified. The impact testing machine body will control the third hydraulic rod to push the collection box out from the discharge port. If it is not qualified, it will continue to move backward until it is discharged, realizing the classified storage of fractured pieces for convenient subsequent inspection.

[0021] S3: After the test piece is tested, the telescopic rod pushes the sliding plate to slide stably along the first and second limit axes until it moves to one side of the first and second positioning plates. The third stepper motor is started to drive the threaded shaft to rotate, which in turn drives the first connecting plate, the second connecting plate, the negative pressure frame, and the sliding plate to move in the direction of the pendulum. During this process, the position of the sliding plate is adjusted by the telescopic rod to avoid collision with the second and first positioning plates and to make it fit against the force-bearing surface of the rectangular frame. The negative pressure pump is started to draw the negative pressure frame into negative pressure and suck up the debris on the surface of the rectangular frame through the hose and the negative pressure pipe. When the sliding plate fits against the force-bearing surface, the bullseye bearing pushes the force-bearing shaft and the pressure plate to stop squeezing the second inductive touch metal button. Only then will the impact testing machine body control its operation. If the force-bearing surface of the rectangular frame is concave, the bullseye bearing moves along the concave surface. Under the action of the return spring, the pressure plate contacts the second inductive touch metal button and sends a concave warning to the outside world.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. This invention, by setting up a recycling unit, can clamp the test piece, and when the test piece is tested and breaks, the recycling unit can still move the broken test piece to the installation position, eliminating the need for manual searching.

[0024] 2. By setting up a storage unit, the present invention can store the detected fractured parts and ensure that they are still in the same rectangular frame after detection and fracture, and will not be mixed in storage, which facilitates subsequent observation of raw materials.

[0025] 3. This invention, by setting up a cleaning mechanism, can clean the surface of the testing table, eliminating the need for manual cleaning. By setting up a recycling unit, a storage unit, and a cleaning mechanism, it effectively avoids the problem of requiring staff to recycle broken testing instruments and clean the surface of the testing table during equipment use.

Detailed Implementation

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1: Please refer to Figure 1 , Figures 7-10 The present invention provides a technical solution: a device for testing the mechanical properties of titanium alloy forgings. The present invention makes corresponding improvements to the technical problems mentioned in the background art, including an impact testing machine body 1, a recycling mechanism 2 provided on the outside of the impact testing machine body 1, and a cleaning mechanism 3 provided on the outside of the impact testing machine body 1.

[0041] The recycling mechanism 2 includes a recycling unit 21, which is located on the outside of the impact testing machine body 1. The recycling unit 21 can reduce the steps of recycling the broken test piece after testing.

[0042] The recycling mechanism 2 also includes a storage unit 22, which is located on the outside of the impact testing machine body 1. The storage unit 22 can store the recovered broken parts separately.

[0043] The cleaning mechanism 3 can clean the residue on the surface of the testing station.

[0044] As a further definition of the recycling mechanism 2 of the present invention, the recycling unit 21 includes two rectangular frames 2101. The bottom surface of each rectangular frame 2101 is fixedly connected to the outer surface of the impact testing machine body 1. A support plate 2108 is fixedly connected to the inner wall of each rectangular frame 2101. A first stepper motor 2105 is fixedly connected to the upper surface of each support plate 2108. A rotating shaft 2104 is fixedly connected to the output end of each first stepper motor 2105. The outer surface of each rotating shaft 2104 is rotatably connected to the inner wall of the rectangular frame 2101. A transmission rope 2106 is fixedly connected to the outer surface of each rotating shaft 2104. One end of each transmission rope 2106 passes through the rectangular frame 2101 and extends to the outside of the rectangular frame 2101. One end of each moving rope 2106 is fixedly connected to a first positioning plate 2103. A second positioning plate 2102 is provided on one side of each first positioning plate 2103. The bottom surface of each second positioning plate 2102 and the bottom surface of each first positioning plate 2103 are in contact with the outer surface of the rectangular frame 2101. Two first fixing bolts 2107 are rotatably connected to the inner wall of each first positioning plate 2103. The outer surface of each first fixing bolt 2107 is threaded to the inner wall of the second positioning plate 2102. By setting up a recycling unit 21, the detection piece can be clamped. When the detection piece is detected and broken, the recycling unit 21 can still move the broken detection piece to the installation position, eliminating the need for manual searching.

[0045] Please see Figure 10 Each rectangular frame 2101 has two fixed brackets 2109 fixedly connected to its inner wall, and two mounting blocks 2110 fixedly connected to the outer surface of each fixed bracket 2109. A first roller 2111 is rotatably connected to the inner wall of each pair of mounting blocks 2110. The outer surface of each first roller 2111 is in contact with the outer surface of the transmission rope 2106. By setting the fixed brackets 2109, mounting blocks 2110 and first rollers 2111, the position of the transmission rope 2106 can be defined.

[0046] Please see Figure 10Each rectangular frame 2101 has a mounting bracket 2113 fixedly connected to its inner wall. One side of each mounting bracket 2113 is fixedly connected to one side of the fixing bracket 2109. A rectangular plate 2115 is fixedly connected to the outer surface of each mounting bracket 2113 and the inner wall of the rectangular frame 2101. By providing the mounting bracket 2113, an installation position can be provided for the rectangular plate 2115.

[0047] Please see Figure 10 Each rectangular plate 2115 has a fixed block 2114 fixedly connected to its upper and lower surfaces. Each fixed block 2114 has a first hydraulic rod 2112 fixedly connected to its inner wall. Each pair of first hydraulic rods 2112 has a sliding frame 2117 fixedly connected to their telescopic ends. Each sliding frame 2117 has a second stepper motor 2119 fixedly connected to its upper and lower surfaces. Each output of the second stepper motor 2119 has a hexagonal block 2118 fixedly connected to its output. Each hexagonal block 2118 is located inside the first fixing bolt 2107. With the second stepper motor 2119 installed, the second stepper motor 2119 can drive the hexagonal block 2118 to rotate, which in turn drives the first fixing bolt 2107 to rotate, providing power for its rotation.

[0048] Please see Figure 10 Each sliding frame 2117 has two sets of second rollers 2116 rotatably connected to its inner wall. Each set of second rollers 2116 consists of two rollers. The outer surface of each second roller 2116 is in contact with the outer surface of the rectangular plate 2115. By providing the second rollers 2116, the second rollers 2116 can reduce the friction when the sliding frame 2117 moves.

[0049] The specific implementation method of this embodiment is as follows: When this device is needed, it should be understood that all the electric drive structures in this application are electrically connected to the impact testing machine body 1 through wires. First, the pendulum of the impact testing machine body 1 is rotated and locked to a suitable height. Then, the test piece to be tested is placed between the two second positioning plates 2102 and the first positioning plate 2103. At this time, the test piece will be stably stopped between the second positioning plates 2102 and the first positioning plate 2103 under the support of the two rectangular frames 2101. Subsequently, the second stepper motor 2119 is controlled to run. The running of the second stepper motor 2119 will drive the hexagonal block 2118 to rotate, thereby driving the first fixing bolt 2107 to rotate. At this time, the first fixing bolt 2107... The first positioning plate 2103 rotates within the inner wall of the first positioning plate 2103. Combined with the threaded connection between the first fixing bolt 2107 and the second positioning plate 2102, this allows the second positioning plate 2102 to move closer to the position of the first positioning plate 2103. At this point, the two second positioning plates 2102 move the workpiece to be inspected towards the position of the first positioning plate 2103 until the workpiece is clamped. It's important to understand that the bottom surfaces of both the first and second positioning plates 2103 are in contact with the upper surface of the rectangular frame 2101. Therefore, the first and second positioning plates 2103 and 2102 cannot rotate under the action of the first fixing bolt 2107. Thus, the first fixing bolt 2107 can only rotate within the first positioning plate 2103. The internal rotation of the first positioning plate 2103 causes the second positioning plate 2102 to move laterally under the action of the first fixing bolt 2107. Both the first and second positioning plates 2103 and 2102 are covered with rubber on the side that contacts the workpiece to be tested, increasing friction. Furthermore, the first positioning plate 2103 is retracted into the rectangular frame 2101, ensuring that the surface of the workpiece can completely conform to the side of the rectangular frame 2101. Therefore, when the workpiece is tested, the impact force is entirely applied to the side of the rectangular frame 2101. A large gap exists between the first positioning plate 2103 and the rectangular frame 2101. Subsequently, the first hydraulic rod 2112 drives the sliding frame 211... 7. The second stepper motor 2119 moves until the hexagonal block 2118 disengages from the outside of the first fixing bolt 2107. Then, the pendulum in the impact testing machine body 1 is controlled to fall and impact the test piece. The test piece will break after being impacted, and the first stepper motor 2105 is not in the locked state at this time. Therefore, when the test piece is impacted and splits into two pieces, it will fall out of the device along with the first positioning plate 2103 and the second positioning plate 2102. This process will pull the transmission rope 2106 to unfold. Therefore, after the test piece is tested, the first stepper motor 2105 is controlled to rewind the transmission rope 2106 onto the rotating shaft 2104, which will drive the first positioning plate 2103 and the second positioning plate 2102 to reset.Subsequently, the first hydraulic rod 2112 is controlled to push the second stepper motor 2119 and hexagonal block 2118 again, applying reverse rotational force to the first fixing bolt 2107, causing the second positioning plate 2102 to move away from the first positioning plate 2103. It is important to understand that regardless of whether the second positioning plate 2102 moves away from or closer to the first positioning plate 2103 under the action of the first fixing bolt 2107, the first stepper motor 2105 remains locked, and the first positioning plate 2103 is in close contact with the surface of the rectangular frame 2101 under the action of the transmission rope 2106. This achieves the purpose of recovering the broken detection component.

[0050] Example 2: Please refer to Figure 1 , Figure 2 , Figure 11 and Figure 12 The present invention provides a technical solution: a device for testing the mechanical properties of titanium alloy forgings. The present invention makes corresponding improvements to the technical problems mentioned in the background art.

[0051] As a further definition of the recycling mechanism 2 of the present invention, the storage unit 22 includes a long frame 2201. The outer surface of the long frame 2201 is fixedly connected to the inner wall of the impact testing machine body 1. Several identical collection frames 2205 are slidably connected inside the long frame 2201. Two guide frames 2204 are fixedly connected to the inner wall of the long frame 2201. One side of each guide frame 2204 penetrates through the rectangular frame 2101 and extends into the interior of the rectangular frame 2101. One side of each guide frame 2204 is fixedly connected to the inner top wall of the rectangular frame 2101. A disassembly plate 2206 is provided inside the impact testing machine body 1. Two sets of force springs 2212 are fixedly connected to the upper surface of the disassembly plate 2206. Each set of force springs 2212 consists of two springs. The top of the force spring 2212 is fixedly connected to the lifting plate 2210. The upper surface of the lifting plate 2210 is in contact with the bottom surface of one of the collection frames 2205. The upper surface of the disassembly plate 2206 is fixedly connected to the first inductive touch metal button 2208. The outer surface of the impact testing machine body 1 is fixedly connected to the mounting plate 2203. The inner wall of the mounting plate 2203 is fixedly connected to the second hydraulic rod 2202. The inner wall of the impact testing machine body 1 is fixedly connected to the third hydraulic rod 2211. By setting the storage unit 22, the fractured parts after testing can be stored, and it can be ensured that the fractured parts are still in the same rectangular frame 2101 and will not be mixed for storage, which is convenient for subsequent observation of raw materials.

[0052] Please see Figure 12The inner wall of the disassembly plate 2206 and the inner wall of the impact testing machine body 1 are connected by two second fixing bolts 2209. One side of the rectangular frame 2101 and the other side of the impact testing machine body 1 are provided with a discharge port 2207. By setting the second fixing bolts 2209, the disassembly plate 2206 can be disassembled, which is convenient for replacing the force springs 2212 with different elasticity.

[0053] The specific implementation of this embodiment is as follows: When using the storage unit 22, it should be understood that the number of broken segments after the test piece is tested is normally at both ends. Therefore, the more broken segments there are, the more factors affecting the quality, such as air bubbles inside the test piece, and the worse the quality. Conversely, the fewer broken segments there are, the better the quality. In addition, after the test piece is placed, the collection frame 2205 needs to be placed behind the second hydraulic rod 2202 and directly facing the entrance of the long frame 2201. Then the recovery unit 21 runs, and the pendulum falls to complete the test. The recovery unit 21 then completes the recovery work, and the broken piece will enter the collection frame 2205. If the weight is qualified, the first inductive touch metal button 2208 will be triggered; otherwise, it will not. Then the impact testing machine body 1 will control the second hydraulic rod 2202 to push the newly placed collection frame. 2205 enters the long frame 2201. Through the layered transmission of several collection frames 2205 inside the long frame 2201, the collection frame 2205 that just collected the broken parts can be moved to the side of the third hydraulic rod 2211. At this time, it should be understood that after the first inductive touch metal button 2208 is triggered, it means that the weight of the broken parts collected in this collection frame 2205 is qualified. Therefore, after the impact testing machine body controls the operation of the second hydraulic rod 2202, it will control the third hydraulic rod 2211 to push the qualified collection frame 2205 and the broken parts out through the discharge port 2207. Conversely, unqualified broken parts cannot drive the collection frame 2205 to trigger the first inductive touch metal button 2208, nor can they be discharged through the discharge port 2207. This not only achieves the purpose of storage, but also classifies the broken parts that are qualified and unqualified in weight, which is convenient for subsequent inspection by staff.

[0055] As a further limitation of the cleaning mechanism 3 of the present invention, the cleaning mechanism 3 includes two sets of third stepper motors 301, with two third stepper motors 301 in each set. The outer surface of each third stepper motor 301 is fixedly connected to the outer surface of the impact testing machine body 1. The output end of each third stepper motor 301 is fixedly connected to a threaded shaft 303. Two sets of fixing plates 304 are fixedly connected to the upper surface of the long frame 2201, with two fixing plates 304 in each set. The outer surface of each threaded shaft 303 is rotatably connected to the inner wall of the fixing plate 304. The outer surfaces of two threaded shafts 303 are threadedly connected to a first connecting plate 305, and the outer surfaces of the other two threaded shafts 303 are threadedly connected to a second connecting plate 305. 02. A negative pressure frame 306 is fixedly connected to the upper surface of each first connecting plate 305. Two locking holes 314 are opened on one side of each negative pressure frame 306. A locking block 315 is locked inside each locking hole 314. A baffle 316 is fixedly connected to one end of each pair of locking blocks 315. A filter screen 318 is fixedly fixed to the inner top wall of each negative pressure frame 306. A negative pressure pump 319 is fixedly connected to the upper surface of each negative pressure frame 306. An air extraction pipe 320 is fixedly connected to the input end of each negative pressure pump 319. The bottom end of each air extraction pipe 320 passes through the negative pressure frame 306 and extends into the interior of the negative pressure frame 306. An air outlet pipe 326 is fixedly connected to the output end of each negative pressure pump 319. The inner wall of each first connecting plate 305... Each sliding plate 308 is fixedly connected to a telescopic rod 313. A flexible hose 312 is fixedly connected to the upper surface of each sliding plate 308 and the front of the negative pressure frame 306. A negative pressure pipe 310 is fixedly connected to the bottom end of each flexible hose 312. The outer surface of each negative pressure pipe 310 is fixedly connected to the inner wall of the sliding plate 308. Two first limiting shafts 311 are fixedly connected to the front of each sliding plate 308. Each first limiting shaft 311 is slidably connected to the inside of the second connecting plate 302. Two second limiting shafts 317 are fixedly connected to the back of each sliding plate 308. The outer surface of each second limiting shaft 317 is slidably connected to the inside of the first connecting plate 305. The inner wall of the sliding plate 308 is fixedly connected to a detection frame 309. The inner wall of each detection frame 309 is fixedly connected to a partition 321. Several identical force-bearing shafts 323 are slidably connected inside each partition 321. One end of every two force-bearing shafts 323 is fixedly connected to a bullseye bearing 322. The other end of every two force-bearing shafts 323 is fixedly connected to a pressure plate 325. Two return springs 324 are fixedly connected to one side of each pressure plate 325. One end of each return spring 324 is fixedly connected to one side of the partition 321. Several identical second inductive touch metal buttons 307 are fixedly connected to the front of each partition 321. Each force-bearing shaft 323 is located in the inner cavity of the return spring 324.

[0056] The specific implementation of this embodiment is as follows: After the test piece is tested, the telescopic rod 313 will push the sliding plate 308 to move. The sliding plate 308 will slide stably under the action of the first limiting shaft 311 and the second limiting shaft 317, and will stretch the hose 312 until the sliding plate 308 moves to one side of the first positioning plate 2103 and the second positioning plate 2102. Then, the third stepper motor 301 is controlled to run, driving the threaded shaft 303 to rotate, further driving the first connecting plate 305, the second connecting plate 302, the negative pressure frame 306 and the sliding plate 302. The movable plate 308 moves towards the pendulum. After the sliding plate 308 has moved a certain distance, the telescopic rod 313 drives the sliding plate 308 to move until the sliding plate 308 is positioned close to the pendulum on the side of the first positioning plate 2103 and the second positioning plate 2102. It is clear that the telescopic rod 313 pushes the sliding plate 308 to avoid collisions between the sliding plate 308 and the first and second positioning plates 2103 and 2102, and to move the sliding plate 308 close to the pendulum. On one side of the hammer, the sliding plate 308 will contact the side of the rectangular frame 2101 that is subjected to the impact force. Then, the negative pressure pump 319 will be controlled to draw the inside of the negative pressure frame 306 into a negative pressure state. Then, through the hose 312 and the negative pressure pipe 310, any debris that may remain on the surface of the rectangular frame 2101 will be sucked into the negative pressure frame 306. At this point, it should be understood that when the sliding plate 308 moves to the force-bearing surface of the rectangular frame 2101, the bullseye bearing 322 will push the force-bearing shaft 323 and the pressure plate 325 to stop the second inductive touch metal button under the action of the thrust. When button 307 is pressed, the impact testing machine body will control the second inductive touch metal button 307 to operate. When the force-bearing surface of the rectangular frame 2101 is concave, the bullseye bearing 322 will move along the concave surface, and under the action of the return spring 324, it will drive the pressure plate 325 to contact the second inductive touch metal button 307. The second inductive touch metal button 307 transmits information to the impact testing machine body 1, thereby sending out information about the concavity of the force-bearing surface of the rectangular frame 2101 to the outside world, preventing the concave part from affecting the next test result.

[0057] A testing method for a mechanical property testing device for titanium alloy forgings includes the following steps:

[0058] S1: When using the recovery unit 21, first connect all the electrically driven structures of the device to the impact testing machine body 1 via wires. After rotating the pendulum to a suitable height and locking it, place the test piece between the two second positioning plates 2102 and the first positioning plate 2103. Relying on the rectangular frame 2101 for stable support, start the second stepper motor 2119. The hexagonal block 2118 drives the first fixing bolt 2107 to rotate, causing the second positioning plates 2102 to move closer to the first positioning plate 2103 and clamp the test piece. The rubber on the contact surface of the two can increase the friction, and the retraction of the first positioning plate 2103 into the rectangular frame 2101 can ensure that the test piece is subjected to uniform force. Then, the first hydraulic rod 2112 drives the sliding frame 2117 and the second stepper motor 2119 to move, allowing the hexagonal block 2118 to disengage from the first fixing bolt 2107, controlling the pendulum to fall and impact the test piece. The broken test piece will fall along with the second positioning plate 2102 and the first positioning plate 2103 and pull the transmission rope 2106. After the test is completed, the first stepper motor 2105 is started to wind back the transmission rope 2106 to drive the second positioning plate 2102 and the first positioning plate 2103 to reset. Then, the second stepper motor 2119 reverses the operation to move the second positioning plate 2102 away from the first positioning plate 2103, completing the recovery of the broken part.

[0059] S2: When the storage unit 22 is in use, the number of fracture segments of the test piece is related to its quality. The fewer the segments, the better the quality. The more segments, the greater the possibility of internal quality defects such as air bubbles. First, place the collection box 2205 behind the second hydraulic rod 2202 and align it with the entrance of the long frame 2201. After the recycling unit 21 completes the recycling work, the fractured piece will enter the collection box 2205. When the weight is qualified, the first inductive touch metal button 2208 will be triggered. Then, the impact testing machine body 1 controls the second hydraulic rod 2202 to push the collection box 2205 into the long frame 2201. Through the internal transmission of several collection boxes 2205, the collection box 2205 containing the fractured piece is pushed to the side of the third hydraulic rod 2211. If the first inductive touch metal button 2208 is triggered, it means that the weight of the fractured piece is qualified. The impact testing machine body 1 will control the third hydraulic rod 2211 to push the collection box 2205 out of the discharge port 2207. If it is not qualified, it will continue to move backward until it is discharged, thus realizing the classified storage of fractured pieces for convenient subsequent inspection.

[0060] S3: After the test piece is inspected, the telescopic rod 313 pushes the sliding plate 308 to slide stably along the first limiting shaft 311 and the second limiting shaft 317 until it moves to the side of the first positioning plate 2103 and the second positioning plate 2102. Then, the third stepper motor 301 is started to drive the threaded shaft 303 to rotate, thereby driving the first connecting plate 305, the second connecting plate 302, the negative pressure frame 306 and the sliding plate 308 to move in the direction of the pendulum. During this process, the position of the sliding plate 308 is adjusted by the telescopic rod 313 to avoid collision with the second positioning plate 2102 and the first positioning plate 2103 and to make it fit against the rectangular frame 2. When the negative pressure pump 319 is activated, the negative pressure frame 306 is drawn into negative pressure, and debris on the surface of the rectangular frame 2101 is sucked in through the hose 312 and the negative pressure pipe 310. When the sliding plate 308 is in contact with the negative pressure surface, the bullseye bearing 322 pushes the force shaft 323 and the pressure plate 325 to stop squeezing the second inductive touch metal button 307, and the impact testing machine body 1 will then control its operation. If the negative pressure surface of the rectangular frame 2101 is concave, the bullseye bearing 322 moves along the concave surface, and under the action of the return spring 324, the pressure plate 325 contacts the second inductive touch metal button 307, sending a concave warning to the outside world.
