Description

Technical Field

[0001] This utility model belongs to the field of materials science and technology, and in particular relates to a device for detecting stress in forgings. Background Technology

[0002] A forging stress testing device is a device used to detect and evaluate the internal stress state of forgings during the forging process. During the forging process, residual stress is generated due to the plastic deformation of the material, and these stresses will affect the performance and quality of the forgings, so they need to be detected and analyzed.

[0003] When scanning and inspecting forgings, any slight vibration or displacement will cause the measurement signal to be distorted, which will directly change the stress distribution or the position of the detector relative to the measured point and introduce significant errors. Therefore, we propose a forging stress detection device. Summary of the Invention

[0004] The purpose of this invention is to provide a forging stress detection device. By rotating the knob, the knob drives the threaded rod to rotate, and then the threaded rod causes the threaded cylinder to move downward. Then, the threaded cylinder clamps the forging with a soft pad through transmission, thus solving the problem of fixing the forging during testing.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a forging stress detection device, including a base, a support frame fixedly connected to the top of the base, a fixing mechanism on the base, and a detection mechanism on the support frame;

[0007] The fixing mechanism includes a limiting ring, a threaded rod rotatably connected to the inner wall of the limiting ring, a knob fixedly connected to the outer surface of the threaded rod, an L-shaped block fixedly connected to the outer surface of the base, a bolt threadedly connected to the inner wall of the L-shaped block, a threaded cylinder threadedly connected to the outer surface of the threaded rod, a connecting rod rotatably connected to the inner wall of the threaded cylinder, a moving block rotatably connected to the end of the connecting rod away from the threaded cylinder, a sliding groove opened inside the base, a limiting block slidably connected to the inner wall of the sliding groove, and a soft pad fixedly connected to the top of the moving block.

[0008] Furthermore, there are two limiting rings, the outer surface of the limiting rings is fixedly connected to the outer surface of the base, the bottom of the bolt contacts the top of the knob, and there are several connecting rods.

[0009] Furthermore, the outer surface of the moving block is slidably connected to the inner wall of the base, a plurality of sliding grooves are provided, and the outer surface of the limiting block is fixedly connected to the outer surface of the moving block.

[0010] Furthermore, the detection mechanism includes a motor frame fixedly connected to the outer surface of the support frame, a motor fixedly connected to the inner wall of the motor frame, and a threaded rod connected to the output shaft of the motor via a coupling.

[0011] Furthermore, a fixing block is rotatably connected to the outer surface of the second threaded rod, and a plurality of fixing blocks are provided. The bottom of the fixing block is fixedly connected to the top of the support frame, and a moving block is threadedly connected to the outer surface of the second threaded rod.

[0012] Furthermore, there are two movable blocks in total. A limiting rod is slidably connected to the inner wall of the right movable block, and the outer surface of the limiting rod is fixedly connected to the inner wall of the fixed block.

[0013] Furthermore, a sliding frame is fixedly connected to the bottom of the movable block, the inner wall of the sliding frame is slidably connected to the outer surface of the support frame, a connecting block is fixedly connected to the inner wall of the sliding frame, and the outer surface of the connecting block is slidably connected to the inner wall of the support frame.

[0014] Furthermore, a connecting frame is fixedly connected to one side of the sliding frames that are close to each other, and an X-ray scanner is fixedly connected to the inner wall of the connecting frame.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a soft pad. When the knob is rotated, it drives the threaded rod to rotate. The rotation of the threaded rod causes the threaded cylinder to move downwards along the threaded rod. The threaded cylinder then pulls the connecting rod downwards, which in turn pulls the moving blocks closer together. By using the soft pad to clamp and fix the forging, the forging can be fixed during testing. This effectively isolates the forging's position from external vibrations and the vibration of the testing equipment itself, preventing displacement of the forging due to insufficient fixation and ensuring the accuracy of the test results.

[0017] 2. This utility model incorporates a connecting frame. The motor causes the threaded rod two to rotate, which in turn causes the moving block to move towards the motor. The moving block then drives the sliding frame to slide on the support frame. At this time, the sliding frame also drives the connecting block to slide within the support frame. By using a connecting frame that can slide on the support frame, the X-ray scanner can perform a stable scan of the forging. Stable scanning ensures that the geometric relationship between the equipment and the forging surface is strictly consistent, avoiding systematic errors introduced by vibration or shaking.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] 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.

[0029] Please see Figure 1-6As shown, this utility model is a forging stress detection device, including a base 101, a support frame 102 fixedly connected to the top of the base 101, a fixing mechanism 2 provided on the base 101, and a detection mechanism 3 provided on the support frame 102. This device clamps and fixes the forging through the fixing mechanism 2, and then performs a smooth scan on the forging through the detection mechanism 3 to detect the stress of the forging.

[0030] The fixing mechanism 2 includes a limiting ring 201, with a threaded rod 202 rotatably connected to the inner wall of the limiting ring 201. A knob 203 is fixedly connected to the outer surface of the threaded rod 202. An L-shaped block 204 is fixedly connected to the outer surface of the base 101. The knob 203 can be rotated, which drives the threaded rod 202 to rotate. The threaded rod 202 then enables the device to proceed to the next transmission step. A bolt 205 is threadedly connected to the inner wall of the L-shaped block 204, and a bolt 205 is threadedly connected to the outer surface of the threaded rod 202. A threaded cylinder 206 is connected, and a connecting rod 207 is rotatably connected to the inner wall of the threaded cylinder 206. A moving block 208 is rotatably connected to the end of the connecting rod 207 away from the threaded cylinder 206, allowing the bolt 205 to be tightened within the L-shaped block 204. At this time, the bolt 205 will tightly fit against the knob 203, thus fixing the knob 203 and preventing the threaded rod 202 from rotating during device operation. A sliding groove 210 is provided inside the base 101, and a limit block 209 is slidably connected to the inner wall of the sliding groove 210. A soft pad 211 is fixedly connected to the top of the moving block 208. Two limit rings 201 are provided. Limit blocks 209 restrict the movement of the moving block 208, allowing it to slide only along the slide groove 210. This enables the moving block 208 to drive the soft pad 211 to clamp and fix the forging. The outer surface of the limit rings 201 is fixedly connected to the outer surface of the base 101. The bottom of the bolt 205 contacts the top of the knob 203. Several connecting rods 207 are provided. 201 fixes the position of the threaded rod 202 to prevent it from shifting within the device due to rotation, ensuring stable transmission. The outer surface of the moving block 208 is slidably connected to the inner wall of the base 101. Several slide grooves 210 are provided. The outer surface of the limiting block 209 is fixedly connected to the outer surface of the moving block 208. The slide grooves 210 restrict the movement trajectory of the limiting block 209, thereby limiting the movement of the moving block 208 and preventing it from shifting.

[0031] The testing mechanism 3 includes a motor frame 301 fixedly connected to the outer surface of the support frame 102. A motor 302 is fixedly connected to the inner wall of the motor frame 301. A threaded rod 303 is fixedly connected to the output shaft of the motor 302 via a coupling. A fixing block 304 is rotatably connected to the outer surface of the threaded rod 303. The motor frame 301 fixes the motor 302 to prevent the motor 302 from rotating due to rotation, ensuring stable transmission of the device. Several fixing blocks 304 are provided. The bottom of the fixing block 304 is fixedly connected to the top of the support frame 102. The outer surface of the threaded rod 303 is fixedly connected to the outer surface of the threaded rod 303. The threaded connection includes a movable block 306. The motor 302 can drive the threaded rod 303 to rotate. At this time, the rotation of the threaded rod 303 will cause the movable block 306 to move along the threaded rod 303, thereby enabling the device to proceed to the next transmission step. There are two movable blocks 306. The inner wall of the right movable block 306 is slidably connected to a limit rod 305. The outer surface of the limit rod 305 is fixedly connected to the inner wall of the fixed block 304. The limit rod 305 restricts the position of the movable block 306 to prevent the movable block 306 from being displaced due to rotation, ensuring that the device can perform detection smoothly.

[0032] A sliding frame 307 is fixedly connected to the bottom of the movable block 306. The inner wall of the sliding frame 307 is slidably connected to the outer surface of the support frame 102. A connecting block 308 is fixedly connected to the inner wall of the sliding frame 307. The connecting block 308 further restricts the position of the sliding frame 307 to prevent the sliding frame 307 from shifting on the support frame 102 and ensure the normal operation of the device. The outer surface of the connecting block 308 is slidably connected to the inner wall of the support frame 102. A connecting frame 309 is fixedly connected to the side of the sliding frames 307 that are close to each other. An X-ray scanner 310 is fixedly connected to the inner wall of the connecting frame 309. The connecting frame 309 can drive the X-ray scanner 310 to move, so that the X-ray scanner 310 can perform an all-round scan of the forging and perform a more comprehensive detection of the stress of the forging.

[0033] One specific application of this embodiment is:

[0034] When the operator needs to use the equipment, first place the forging between the four soft pads 211, then turn the knob 203. The knob 203 will then rotate the threaded rod 202. The rotation of the threaded rod 202 will cause the threaded cylinder 206 to move downwards along the threaded rod 202. The threaded cylinder 206 will then pull the connecting rod 207 downwards, which in turn will pull the moving block 208 closer together. Since the limiting block 209 can only slide within the groove 210, the moving block 208 can only move along the groove 210. The moving block 208 will then clamp the soft pads 211, achieving the effect of fixing the forging during testing. This effectively isolates the forging's position from external vibrations and the vibration of the testing equipment itself, preventing displacement due to insufficient fixing and ensuring the accuracy of the test results. At this point, the bolts can be... Tighten 205 inside the L-shaped block 204 to fix the knob 203. At this time, the motor 302 can be started. The motor 302 will cause the threaded rod 303 to rotate. Then, the rotation of the threaded rod 303 will cause the moving block 306 to move in the direction of the motor 302. Then, the moving block 306 will drive the sliding frame 307 to slide on the support frame 102. At this time, the sliding frame 307 will also drive the connecting block 308 to slide inside the support frame 102. Then, the connecting frame 309 will drive the fixed block 304 on the other side to slide on the limit rod 305. Then, the connecting frame 309 will drive the X-ray scanner 310 to move, so that the X-ray scanner 310 can scan the forging smoothly. This achieves the effect of ensuring that the geometric relationship between the equipment and the surface of the forging is strictly consistent, avoiding the introduction of systematic errors due to vibration or shaking.
