Description

Technical Field

[0001] This invention relates to the field of crankshaft magnetic particle inspection technology, and in particular to a multi-station crankshaft magnetic particle inspection machine. Background Technology

[0002] In the production process of crankshafts, magnetic particle testing is often required to understand the quality of the finished crankshaft. However, in the existing technology, traditional crankshaft testing usually uses single-station testing equipment. Before the next crankshaft is loaded for testing, it is necessary to wait for the previous crankshaft to unload, which increases the waiting time for testing and reduces the efficiency of magnetic particle testing. To address this issue, we propose a multi-station crankshaft magnetic particle testing machine. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as the fact that traditional magnetic particle inspection equipment uses a single station to clamp and fix the crankshaft, and after completing one magnetic particle inspection, it needs to wait for unloading and loading, which is inefficient. Therefore, a multi-station crankshaft magnetic particle inspection machine is proposed.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A multi-station crankshaft magnetic particle flaw detector includes four support rods, each with a worktable fixedly mounted on it. The four support rods are respectively fixed at the four corners of the worktable. Side plates are fixedly mounted on the worktable, and a top plate is fixedly mounted on each side plate. An electrically controlled telescopic seat is fixedly mounted on the lower wall of the top plate. A mounting base is fixedly connected to the output end of the electrically controlled telescopic seat. A flaw detection head is fixedly connected to the lower wall of the mounting base and is fixedly mounted on the mounting base via a fixing mechanism. A magnetic particle adding mechanism is provided on the top plate. A rotating ring is also rotatably mounted on the worktable. Several clamping platforms are circumferentially fixed on the rotating ring, each with a clamping mechanism. An opening is also provided on the worktable, corresponding to the inner ring of the rotating ring. A base plate is fixedly mounted on the lower wall of the worktable and connected to the lower wall of the worktable via a connecting plate. A collection box is fixedly placed on the base plate, corresponding to the opening on the worktable.

[0006] Preferably, the fixing mechanism includes two locking blocks. The lower wall of the mounting base has a slot corresponding to the flaw detection head. The two side walls of the slot have telescopic grooves corresponding to the locking blocks. The two locking blocks are slidably disposed in the two telescopic grooves, and the two locking blocks are connected to the inner wall of the telescopic grooves by telescopic springs. The two side walls of the flaw detection head have slots corresponding to the locking blocks. The side wall of the two locking blocks near the slot opening is inclined, and the two locking blocks are provided with corresponding pulling mechanisms.

[0007] Preferably, the pulling mechanism includes two pull rods, which are respectively fixedly mounted on the side wall of the two blocks near the telescopic spring, and the two pull rods are respectively slidably mounted through the side walls of the mounting base. Each of the two pull rods is fixedly connected to a handle at the end away from the block.

[0008] Preferably, the magnetic powder adding mechanism includes a magnetic powder box, which is fixedly mounted on a top plate. The lower wall of the magnetic powder box and the top plate each have a corresponding discharge port. A guide trough is fixedly connected to the discharge port on the top plate. The end of the guide trough near the workbench is inclined towards the lower side of the flaw detection head. The lower wall of the magnetic powder box is inclined towards the discharge port. A baffle is slidably mounted on the side wall of the magnetic powder box. The baffle is L-shaped, and its horizontal plate slides through the side wall of the magnetic powder box to block the discharge port. The vertical plate of the baffle is connected to the outer wall of the magnetic powder box via a return spring. A fan blade is rotatably mounted on the side wall of the side plate. A motor is fixedly mounted on the side wall away from the fan blade. The shaft of the fan blade rotatably passes through the side plate and is fixedly connected to the output end of the motor. A contact switch corresponding to the motor is fixedly mounted on the top plate, and the contact switch is positioned corresponding to the baffle.

[0009] Preferably, the clamping mechanism includes several clamping plates, which are arranged in pairs and slidably mounted on several clamping platforms via sliders. Each clamping platform has a groove corresponding to two sliders thereon, and each groove contains a control mechanism corresponding to a slider.

[0010] Preferably, the control mechanism includes a plurality of threaded rods, which are rotatably disposed in a plurality of sliding grooves. Each threaded rod rotatably passes through two sliders in its respective sliding groove. Each slider has a threaded through hole corresponding to the threaded rod. The threads at both ends of each threaded rod are arranged in opposite directions. One end of each threaded rod is rotatably connected to a rotating handle that passes through the side wall of the clamping table.

[0011] Compared with the prior art, the beneficial effects of this invention are as follows: The screw rod and slider work together to control the clamping plate, enabling rapid clamping and fixing of the crankshaft on the clamping platform. By setting multiple clamping platforms, magnetic particle testing can be performed on one crankshaft on one platform while unloading the previous crankshaft and loading and fixing the next crankshaft, greatly reducing the waiting time for loading and unloading crankshafts and thus improving the efficiency of magnetic particle testing. The rotating ring facilitates quick and easy delivery of the fixed crankshaft to the underside of the testing head. The pull rod controls the locking block; pulling the pull rod causes the locking block to slide out of the slot, allowing for rapid disassembly of the testing head. This allows for replacement of the crankshaft according to its model. The same model of flaw detection head allows for convenient and quick maintenance. A baffle blocks the magnetic powder box outlet. When the crankshaft rotates to the underside of the flaw detection head, the control unit opens, and the electronically controlled telescopic seat moves the flaw detection head down to fit the crankshaft. Then, the baffle is pulled, the contact switch is pressed, the motor is turned off, and the fan stops blowing air. Magnetic powder is allowed to fall onto the crankshaft through the guide chute to assist in flaw detection. When enough magnetic powder is available, the baffle is released, and under the action of the return spring, the baffle returns to its original position, blocking the outlet and stopping the discharge of magnetic powder. At this time, the motor starts, and the fan rotates, blowing away excess magnetic powder into the collection box. The magnetic powder remaining on the crankshaft corresponds to the flaws on the crankshaft, thus completing the magnetic powder flaw detection operation. Attached Figure Description

The mounting base 7 is equipped with two telescopic slots 26, and both locking blocks 25 are connected to the inner wall of the telescopic slots 26 via telescopic springs 27. The two side walls of the flaw detection head 8 are provided with corresponding slots for the locking blocks 25. The side walls of the two locking blocks 25 near the opening of the slot 24 are inclined, and each locking block 25 is equipped with a corresponding pulling mechanism. The pulling mechanism includes two pull rods 28, which are fixedly mounted on the side walls of the two locking blocks 25 near the telescopic springs 27, and slide through the two side walls of the mounting base 7. A handle 29 is fixedly connected to the end of each pull rod 28 away from the locking block 25. A magnetic powder adding mechanism is provided on the top plate 4, which includes a magnetic powder box 5 and magnetic powder... Box 5 is fixedly mounted on top plate 4. Both the lower wall of magnetic powder box 5 and the top plate 4 have corresponding discharge ports. A guide trough 9 is fixedly connected to the discharge port on top plate 4. The end of the guide trough 9 near the workbench 2 is inclined towards the lower side of the flaw detection head 8. The lower wall of magnetic powder box 5 is inclined towards the discharge port. A baffle 19 is slidably mounted on the side wall of magnetic powder box 5. The baffle 19 is L-shaped, and its horizontal plate slides through the side wall of magnetic powder box 5 to block the discharge port. The vertical plate of the baffle 19 is connected to the outer wall of magnetic powder box 5 via a return spring 20. A fan blade 22 is rotatably mounted on the side wall of side plate 3. A motor 23 is fixedly mounted on the side wall of side plate 3 away from the fan blade 22. The shaft of the fan blade 22 rotatably passes through the side plate 3 and... The output end of motor 23 is fixedly connected. A contact switch 21 corresponding to motor 23 is fixedly installed on top plate 4. The contact switch 21 is positioned corresponding to baffle 19. A rotating ring 10 is also rotatably installed on worktable 2. Several clamping platforms 11 are fixedly installed circumferentially on rotating ring 10. Each clamping platform 11 is equipped with a clamping mechanism, which includes several clamping plates 13. The clamping plates 13 are slidably installed on the clamping platforms 11 in pairs via sliders 12. Each clamping platform 11 has a groove 14 corresponding to the two sliders 12 on it. Each groove 14 is equipped with a control mechanism corresponding to the slider 12. The control mechanism includes several threaded rods 15, which are rotatably installed in the grooves 14.Each threaded rod 15 is rotatably inserted through two sliders 12 within the slide groove 14. Each slider 12 has a threaded through hole corresponding to the threaded rod 15. The threads at both ends of each threaded rod 15 are reversed. One end of each threaded rod 15 is rotatably inserted through the side wall of the clamping table 11 and fixedly connected to a handle 16. The worktable 2 also has an opening, which corresponds to the inner ring of the rotating ring 10. A base plate 17 is fixedly installed on the lower wall of the worktable 2. The base plate 17 is connected to the lower wall of the worktable 2 via a connecting plate. A collection box 18 is fixedly placed on the upper part, and the collection box 18 is set to correspond to the opening on the worktable 2. Through the cooperation of the threaded rod 15 and the slider 12, the clamping plate 13 is controlled, so that the crankshaft can be quickly clamped and fixed on the clamping table 11. By setting multiple clamping tables 11, the crankshaft on one clamping table 11 can be subjected to magnetic particle inspection while the previous crankshaft is unloaded and the next crankshaft is loaded and fixed, which greatly reduces the waiting time for loading and unloading crankshafts, thereby improving the efficiency of magnetic particle inspection. By setting a rotating ring 10 This design facilitates quick and easy placement of the fixed crankshaft to the underside of the flaw detection head 8. A pull rod 28 controls the locking block 25; pulling the rod 28 causes the locking block 25 to slide out of the slot, allowing for quick disassembly of the flaw detection head 8. This allows for the replacement of different models of the flaw detection head 8 according to the crankshaft model and facilitates convenient and quick maintenance of the flaw detection head 8. A baffle 19 blocks the discharge port of the magnetic powder box 5. When the crankshaft rotates to the underside of the flaw detection head 8, the electronically controlled extension and retraction of the flaw detection head 8 is activated. After the seat 6 moves the flaw detection head 8 down to fit against the crankshaft, it pulls the baffle 19, presses the contact switch 21, shuts off the motor 23, and stops the fan blades 22 from blowing air. This allows magnetic powder to fall onto the crankshaft through the guide chute 9 to assist in flaw detection. When there is enough magnetic powder, the baffle 19 is released, and under the action of the return spring 20, the baffle 19 returns to its original position, blocking the outlet and stopping the discharge of magnetic powder. At this time, the motor 23 starts, and the fan blades 22 rotate, blowing away excess magnetic powder and causing it to fall into the collection box 18. The magnetic powder remaining on the crankshaft corresponds to the flaws on the crankshaft, thus completing the magnetic powder flaw detection operation.

[0020] In this invention, during the magnetic particle inspection of the crankshaft, the threaded rod 15 and the slider 12 work together to control the clamping plate 13, thereby quickly clamping and fixing the crankshaft onto the clamping table 11. By setting multiple clamping tables 11, magnetic particle inspection of the crankshaft on one clamping table 11 can be performed simultaneously with unloading the previous crankshaft and loading and fixing the next crankshaft, greatly reducing the waiting time for loading and unloading crankshafts and thus improving the efficiency of magnetic particle inspection. The rotating ring 10 facilitates the quick and easy delivery of the fixed crankshaft to the underside of the inspection head 8. The pull rod 28 controls the locking block 25; pulling the pull rod 28 causes the locking block 25 to slide out of the slot, allowing for quick disassembly of the inspection head 8. This allows for the replacement of different types of crankshafts according to their model. The flaw detection head 8 is convenient and quick to maintain. By setting baffle 19, the discharge port of magnetic powder box 5 is blocked. When the crankshaft rotates to the lower side of the flaw detection head 8, the control of the electronic telescopic seat 6 drives the flaw detection head 8 to move down and fit against the crankshaft. Then, the baffle 19 is pulled, the contact switch 21 is squeezed, the motor 23 is turned off, and the fan blade 22 stops blowing air. The magnetic powder falls onto the crankshaft through the guide groove 9 to assist in flaw detection. When there is enough magnetic powder, the baffle 19 is released. Under the action of the return spring 20, the baffle 19 returns to its original position, blocking the discharge port and stopping the discharge of magnetic powder. At this time, the motor 23 is turned on, and the fan blade 22 rotates, blowing away the excess magnetic powder and letting it fall into the collection box 18. The magnetic powder left on the crankshaft corresponds to the flaws on the crankshaft, thus completing the magnetic powder flaw detection operation.
