During the crankshaft production process, burrs and sharp edges will be generated. The deburring device can effectively remove the burrs and sharp edges generated during the crankshaft processing process to ensure a smooth and flat surface.

[0003] When removing burrs from a crankshaft, the crankshaft to be deburred must first be fixed on an operating table. Traditionally, the crankshaft is fixed on the operating table using bolts, screws, or other fastening devices, and then the burrs on its exterior are removed using a grinding wheel.

[0004] Although this fixing method is simple, it also has some shortcomings: using bolts or screws to fasten the crankshaft may cause imbalance or instability during the processing. This instability may lead to quality problems in the crankshaft during processing and reduce the efficiency of crankshaft processing. Utility Model Content

[0005] In order to make up for the above deficiencies, the utility model provides a surface deburring device for crankshaft production, aiming to improve the problem of fastening using bolts or screws in the prior art, which may cause imbalance or instability of the crankshaft during processing.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Reference Figure 1 、 Figure 2 and Figure 4The present invention provides an embodiment of a surface deburring device for crankshaft production, comprising an operating table 1, a frame 3 fixedly connected to the upper portion of the operating table 1, a mounting bracket 5 fixedly connected to the interior of the frame 3, an adjusting component 7 provided on the exterior of the mounting bracket 5, mounting plates 10 fixedly connected to both sides of the interior of the mounting bracket 5, connecting rods 11 fixedly connected to the periphery of the exterior of the mounting plate 10, a plurality of connecting rods 11 fixedly connected to a mounting plate 12 in the middle, a cylinder 13 fixedly connected to the exterior of the mounting plate 12, a moving block 14 fixedly connected to the output end of the cylinder 13, and a moving block 14 fixedly connected to the exterior of the moving block 14. One end of each of the connecting plates 15 is rotatably connected, and through holes 17 are provided around the inside of the mounting disk 12. Fixed rods 18 are fixedly connected to the inside of multiple through holes 17, and sliders 16 are slidably connected to the outside of multiple fixed rods 18. The other ends of the multiple connecting plates 15 are rotatably connected to the outside of multiple sliders 16, and the outside of multiple sliders 16 are fixedly connected to mounting rods 19. The outside of multiple mounting rods 19 are fixedly connected to arc-shaped clamping plates 20. Protective pads 21 are provided inside the multiple arc-shaped clamping plates 20, and the material of the protective pads 21 is rubber. A chip outlet 4 is provided on the right side inside the frame 3.

[0026] When fixing the crankshaft, first place the two ends of the crankshaft in the middle of the four arc-shaped clamping plates 20 respectively. The arc-shaped clamping plates 20 can fit tightly against the surface of the crankshaft to ensure the stability of the fixation. Next, start the cylinder 13, and the cylinder 13 moves through the movable block 14 fixed at its output end. The movement of the movable block 14 drives the connecting plate 15 connected to the outside for rotation to move. During the movement of the four connecting plates 15, the four sliders 16 connected to the other end for rotation move relative to the outside of the four fixed rods 18. This relative movement method enables the four sliders 16 to synchronously and smoothly push the four mounting rods 19 to move relative to each other. The movement of the mounting rods 19 further drives the relative movement of the four arc-shaped clamping plates 20 fixed to the outside. Through the relative movement of the four arc-shaped clamping plates 20, one end of the crankshaft can be fixed. At the same time, the other end of the crankshaft is also fixed in the same way, and the above operation can be repeated. This automatic method of fixing the crankshaft not only avoids problems such as loosening or falling off of bolts or screws that may occur in traditional fixing methods, but also effectively reduces vibration and impact during the processing process, improving processing accuracy and stability.

[0027] Reference Figure 1 、 Figure 2 and Figure 3, the adjusting component 7 includes a first motor 701, which is arranged on the right side of the outside of the mounting frame 5, and the output end of the first motor 701 is fixedly connected to a screw rod 702, and the external thread of the screw rod 702 is connected to a movable plate 703, and both sides of the inside of the movable plate 703 are fixedly connected to electric push rods 704, and the output ends of the two electric push rods 704 are fixedly connected to an L-shaped plate 705, and the inside of the L-shaped plate 705 is fixedly connected to a second motor 706, and the output end of the second motor 706 is fixedly connected to a frosting disk 707. The right side of the outside of the mounting frame 5 is fixedly connected to a support plate 6, the first motor 701 is fixedly connected to the upper part of the support plate 6, and the two sides of the inside of the mounting frame 5 are fixedly connected to guide rods 9, and the movable plate 703 is slidably connected to the outside of the two guide rods 9. The cabinet door 2 is installed on the front side of the interior of the operating table 1, and the cabinet door 2 is fixedly connected to the outside of the handle. The controller 8 is installed on the right side of the outside of the mounting frame 5, and the controller 8 is electrically connected to the first motor 701 and the second motor 706.

[0028] When the position of the sanding disc 707 needs to be adjusted, the first motor 701 is activated, which drives the screw 702 fixed to the output end to rotate. The rotation of the screw 702 causes the external threaded connection to the movable plate 703 to move laterally outside the two guide rods 9. This method of movement is stable and precise, ensuring smooth and accurate movement of the movable plate 703. As the movable plate 703 moves, the two electric push rods 704 fixed inside also move with it. The main function of these two electric push rods 704 is to provide stable support and thrust, ensuring the smooth movement of the L-shaped plate 705. When the electric push rods 704 move, they drive the L-shaped plate 705 fixed to the output end to move. The movement of the L-shaped plate 705 further drives the movement of the second motor 706 fixed inside. The main function of the second motor 706 is to drive the sanding disc 707 to rotate, thereby achieving grinding and finishing of the crankshaft. By adjusting the position of the second motor 706, we can precisely control the position of the grinding disc 707. This facilitates adjustment of the position of the grinding disc 707 when deburring the crankshaft, allowing for more accurate grinding and trimming of the contact points. This helps ensure the machining quality and dimensional accuracy of the crankshaft.

[0029] Working principle: When fixing the crankshaft, first place the two ends of the crankshaft in the middle of the four arc-shaped clamping plates 20 respectively, and then start the cylinder 13. The cylinder 13 moves with the moving block 14 fixed at the output end, and the movement of the moving block 14 moves with the connecting plate 15 connected to the outside and rotating all around. The four connecting plates 15 move and the four sliders 16 connected to the other end move relative to the outside of the four fixed rods 18. When the four sliders 16 move relative to each other, they move with the four externally fixed mounting rods 19 relative to each other. The four mounting rods 19 move relative to each other and move the four externally fixed arc-shaped clamping plates 20 relative to each other. One end of the crankshaft can be fixed by the four arc-shaped clamping plates 20 relative to each other, and the other end of the crankshaft can be fixed by repeating the above operations. This realizes automatic fixation of the crankshaft and solves the problem of fastening with bolts or screws in the traditional fixing method. This will cause the crankshaft to be unbalanced or unstable during processing, thereby improving the efficiency of crankshaft processing. Then, when the position of the grinding disc 707 needs to be adjusted, the first motor 701 is started, and the first motor 701 rotates the screw rod 702 fixed at the output end. The screw rod 702 rotates and moves the external thread connected to the movable plate 703 laterally outside the two guide rods 9. When the movable plate 703 moves, the two electric push rods 704 fixed inside move. The two electric push rods 704 move and the L-shaped plate 705 fixed at the output end moves. The L-shaped plate 705 moves and the second motor 706 fixed inside moves. The second motor 706 moves and the grinding disc 707 fixed at the output end moves. This facilitates the adjustment of the position of the grinding disc 707 when deburring the crankshaft, thereby more accurately grinding and trimming the contact points. This helps to ensure the processing quality and dimensional accuracy of the crankshaft.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
