Description

Technical Field

[0001] This utility model belongs to the field of mechanical engineering technology, and in particular relates to an adjustable-angle impact testing machine for testing the impact resistance of metallic materials. Background Technology

[0002] Metallic materials are materials composed of metallic elements. They typically possess good electrical and thermal conductivity, strength, and ductility. Their properties can be altered through processing or alloying to meet diverse application requirements. An adjustable-angle impact testing machine for testing the impact resistance of metallic materials is a device used to test the impact resistance of metallic materials under impact loads. The main purpose of this testing machine is to simulate the impact loads that metallic materials may encounter during actual use and to evaluate their strength and toughness.

[0003] Existing impact testing machines for testing the impact resistance of metallic materials place the metallic material in a specific groove before starting the machine to conduct the impact test. This method cannot change the impact position of the metallic material. However, if a fixture is set inside the machine and rotated, the impact angle of the metallic material can be changed, thus allowing for a more comprehensive test and evaluation of the metallic material. Therefore, we have proposed an adjustable-angle impact testing machine for testing the impact resistance of metallic materials. Utility Model Content

The first gear ring is rotated by the movement of the rack, and then the first gear ring drives the rotating shaft to rotate together. After that, the rotating shaft drives the second gear ring to rotate through the first gear, thus solving the problem of allowing the fixture to rotate inside the machine.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is an adjustable-angle impact testing machine for testing the impact resistance of metallic materials, including a base, a swinging machine fixedly connected to one side of the base, a pendulum fixedly connected to the output end of the swinging machine, a rotating mechanism provided on the outer surface of the base, and a clamping mechanism provided inside the base. The rotating mechanism includes a second housing fixedly connected to the outer surface of the base. First housings are fixedly connected to both sides of the base. First gears are respectively provided inside the first housings. A rotating shaft is fixedly connected to the inner wall of each first gear. The rotating shaft is located inside the second housing. A first gear ring is fixedly connected to the outer surface of the rotating shaft. A rack meshes with the bottom of the first gear ring. Connecting blocks are fixedly connected to both sides of the rack. An electric actuator is fixedly connected to one side of each connecting block. One end of the electric actuator is fixedly connected to the inner wall of the second housing. Second gear rings mesh with the top of each first gear. Positioning elements are provided on the inner wall of the first housing for fixing the first gears.

[0006] Furthermore, a first T-shaped strip is fixedly connected to the bottom of the rack, the outer surface of the first T-shaped strip is slidably connected to the inner wall of the base, and two limiting rods are slidably connected to the inner wall of the rack, with both ends of the two limiting rods fixedly connected to the inner wall of the second housing.

[0007] Furthermore, the positioning element includes insert rods that are respectively inserted into the inner wall of the first housing, and the first gear has a plurality of insertion holes that match the outer surface of the insert rods.

[0008] Furthermore, two first limiting rings are fixedly connected to the outer surface of the rotating shaft, and the outer surfaces of the two first limiting rings are rotatably connected to the inner wall of the base.

[0009] Furthermore, the clamping mechanism includes two rotating shells disposed inside the base. The outer surfaces of the two rotating shells are respectively fixedly connected to the outer surface of the second toothed ring. A fixing ring is fixedly connected to the inner wall of each of the two rotating shells. A rotating ring is provided on the outer surface of each fixing ring. Three connecting rods are rotatably connected to the inner wall of each rotating ring. A driven rod is rotatably connected to one end of each of the three connecting rods. A gripper is fixedly connected to one end of each driven rod. A second gear meshes with the outer surface of the rotating ring. A rotating handle is fixedly connected to one side of the second gear.

[0010] Furthermore, a second limiting ring is fixedly connected to the outer surface of the fixed ring, and the outer surface of the second limiting ring is rotatably connected to the inner wall of the rotating ring. A fourth limiting ring is fixedly connected to the outer surface of the rotating shell, and the outer surface of the fourth limiting ring is rotatably connected to the inner wall of the base.

[0011] Furthermore, the inner walls of the grippers are slidably connected with second T-shaped strips, and the outer surfaces of the second T-shaped strips are fixedly connected to the inner walls of the rotating shell.

[0014] This utility model has the following beneficial effects: 1. This utility model incorporates a first gear, which pulls the connecting block on both electric actuators. The connecting block then moves the rack, causing the rack to slide the first T-shaped strip within the base. Simultaneously, the rack slides along the two limiting rods, causing the first gear ring to rotate. The first gear ring then drives the first gear to rotate via a rotating shaft. This rotating shaft also drives the first limiting ring to rotate within the base. By using the first gear to rotate the second gear ring, the entire clamp can be rotated, thereby changing the impact angle of the metal material.

[0015] 2. This utility model incorporates a gripper. Rotating the handle causes the third limiting ring to rotate within the positioning block. Then, rotating the handle causes the second gear to rotate, which in turn causes the rotating ring to rotate clockwise. At this point, the rotating ring rotates on the second limiting ring on the fixed ring. The rotating ring then pulls on the three connecting rods, causing one end of each connecting rod to move closer to each other. The connecting rods then drive the gripper to move via the driven rod. The movement of the gripper by the connecting rods, in turn, achieves the effect of clamping and fixing metal materials of different sizes.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-8 As shown, this utility model is an adjustable-angle impact testing machine for testing the impact resistance of metal materials. It includes a base 101, a swinging machine 102 fixedly connected to one side of the base 101, a pendulum 103 fixedly connected to the output end of the swinging machine 102, a rotating mechanism 2 provided on the outer surface of the base 101, and a clamping mechanism 3 provided inside the base 101. This device can rotate the clamps through the rotating mechanism 2, thereby changing the impact angle of the metal material, and then clamp and fix the metal material through the clamping mechanism 3. The rotating mechanism 2 includes a second housing 202 fixedly connected to the outer surface of the base 101. First housings 201 are fixedly connected to both sides of the base 101. First gears 203 are respectively provided inside the first housings 201. A rotating shaft 204 is fixedly connected to the inner wall of the first gear 203. When the rotating shaft 204 rotates, it drives the first gear 203 to rotate, thus facilitating the next transmission step of the first gear 203. The rotating shaft 204 is located inside the second housing 202. A first gear ring 205 is fixedly connected to the outer surface of the rotating shaft 204. A rack 206 meshes with the bottom of the first gear ring 205. Connecting blocks 207 are fixedly connected to both sides of the rack 206. The rack 206 moves within the second housing 202, and the movement of the rack 206 causes the first gear ring 205 to rotate, thereby causing the first gear ring 205 to drive the rotating shaft 204 to rotate. Electric push rods 208 are fixedly connected to one side of the connecting block 207. One end of the electric push rod 208 is fixedly connected to the inner wall of the second housing 202. The top of the first gear 203 is respectively meshed with the second gear ring 209. The inner wall of the first housing 201 is provided with positioning parts for fixing the first gear 203. The electric push rod 208 will pull the rack 206, thereby moving the rack 206. Then the first gear 203 will drive the second gear ring 209 on its top to rotate, thereby facilitating the second gear ring 209 to drive the clamp to rotate.

[0022] A first T-shaped bar 210 is fixedly connected to the bottom of the rack 206. The outer surface of the first T-shaped bar 210 is slidably connected to the inner wall of the base 101. Two limiting rods 211 are slidably connected to the inner wall of the rack 206. Both ends of the two limiting rods 211 are fixedly connected to the inner wall of the second housing 202. When the rack 206 moves, it will drive the first T-shaped bar 210 to slide in the base 101. At this time, the first T-shaped bar 210 plays a certain limiting role on the rack 206 to prevent the rack 206 from deviating during the movement.

[0023] The positioning component includes a rod 212 that is inserted into the inner wall of the first housing 201. The first gear 203 has several holes 213 that match the outer surface of the rod 212. After the angle is adjusted, the rod 212 can be inserted into the hole 213 on the first gear 203 through the first housing 201 to fix the position of the first gear 203.

[0024] Two first limiting rings 214 are fixedly connected to the outer surface of the rotating shaft 204. The outer surfaces of the two first limiting rings 214 are rotatably connected to the inner wall of the base 101. The rotating shaft 204 will drive the first limiting rings 214 to rotate within the base 101. At this time, the first limiting rings 214 have a limiting function to prevent the rotating shaft 204 from shifting due to rotation.

[0025] The clamping mechanism 3 includes two rotating shells 301 disposed inside the base 101. The outer surfaces of the two rotating shells 301 are respectively fixedly connected to the outer surface of the second toothed ring 209. The inner walls of the two rotating shells 301 are each fixedly connected to a fixing ring 302. The outer surfaces of the fixing rings 302 are respectively provided with rotating rings 303. When the second toothed ring 209 rotates, it will drive the rotating shells 301 to rotate, thereby causing the rotating shells 301 as a whole to drive the metal material to rotate, thus changing the impact angle of the metal material. Three connecting rods 304 are rotatably connected to the inner wall of the rotating ring 303. One end of each connecting rod 304 is rotatably connected to a driven rod 305. One end of the driven rod 305 is fixedly connected to a gripper 306. A second gear 307 meshes with the outer surface of the rotating ring 303. A rotating handle 308 is fixedly connected to one side of the second gear 307. The rotating handle 308 can be rotated, which will drive the second gear 307 to rotate. Then, the second gear 307 will cause the rotating ring 303 to rotate inside the rotating shell 301, thereby facilitating the transmission of the device.

[0026] A second limiting ring 309 is fixedly connected to the outer surface of the fixed ring 302. The outer surface of the second limiting ring 309 is rotatably connected to the inner wall of the rotating ring 303. A fourth limiting ring 315 is fixedly connected to the outer surface of the rotating shell 301. The outer surface of the fourth limiting ring 315 is rotatably connected to the inner wall of the base 101. The rotating ring 303 will rotate along the second limiting ring 309 on the fixed ring 302. At this time, the second limiting ring 309 has a limiting function to prevent the rotating ring 303 from detaching from the fixed ring 302 due to rotation.

[0027] The inner wall of the gripper 306 is slidably connected with a second T-shaped strip 310. The outer surface of the second T-shaped strip 310 is fixedly connected to the inner wall of the rotating shell 301. The second T-shaped strip 310 restricts the movement trajectory of the gripper 306, so that the gripper 306 can always move on the same track, thereby clamping and fixing the metal material more stably.

[0028] A third limiting ring 311 is fixedly connected to the outer surface of the rotating handle 308. A positioning block 312 is rotatably connected to the outer surface of the third limiting ring 311. The outer surface of the positioning block 312 is fixedly connected to the inner wall of the rotating shell 301. When the rotating handle 308 is rotated, it will drive the third limiting ring 311 to rotate within the positioning block 312. At this time, the positioning block 312 prevents the rotating handle 308 from shifting due to rotation.

[0029] A locking block 313 is attached to the outer surface of the rotating handle 308. A bolt 314 is rotatably connected to the inner wall of the locking block 313. The outer surface of the bolt 314 is threaded to the inner wall of the rotating shell 301. After the metal materials are clamped, the locking block 313 can be clamped onto the rotating handle 308. Then, the bolt 314 is tightened into the locking block 313 and the rotating shell 301 to fix the rotating handle 308.

[0030] One specific application of this embodiment is: When the staff needs to use the equipment, they can place both ends of the metal material inside the two rotating shells 301, and then rotate the rotating handle 308 counterclockwise. At this time, the rotating handle 308 will drive the third limiting ring 311 to rotate inside the positioning block 312. Then the rotating handle 308 will drive the second gear 307 to rotate. After that, the second gear 307 will cause the rotating ring 303 to rotate clockwise. At this time, the rotating ring 303 will rotate on the second limiting ring 309 on the fixed ring 302. Then the rotating ring 303 will pull the three connecting rods 304, causing one end of the three connecting rods 304 to move towards each other. Then the connecting rod 304 will drive the gripper 306 to move through the driven rod 305. At this time, the gripper 306 will slide along the second T-shaped strip 310, so that the three grippers 306 can clamp the metal material, achieving the effect of clamping and fixing metal materials of different sizes. After clamping is completed, the locking block 313 can be locked onto the rotating handle 308, and then the bolt 314 can be tightened into the locking block 313 inside the rotating housing 301 to fix the position of the rotating handle 308. When it is necessary to change the impact angle of the metal material, two electric actuators 208 can be activated. At this time, both electric actuators 208 will pull the connecting block 207, and then the connecting block 207 will drive the rack 206 to move. At this time, the rack 206 will drive the first T-shaped bar 210 to slide within the base 101. At the same time, the rack 206 will slide along the two limit rods 211. Then the rack 206 will cause the first gear ring 205 to rotate. After that, the first gear ring 205 will drive the first gear 203 to rotate through the rotating shaft 204. At this time, the rotating shaft 204 will also drive the first limit ring 214 to rotate within the base 101. Then, the first gear 203 will drive the second gear ring 209 to rotate, thereby causing the second gear ring 209 to drive the rotating housing 301 to rotate as a whole, achieving the effect of rotating the entire fixture and changing the impact angle of the metal material. Then, the insertion rod 212 can be inserted into the insertion hole 213 on the first gear 203 through the first housing 201 to fix the position of the first gear 203. Finally, the swing machine 102 can be started. At this time, the swing machine 102 will make the pendulum 103 swing, thereby allowing the pendulum 103 to perform an impact test on the metal material.
