[0020] The length of the crankshaft that can be clamped by the clamping mechanism 4 can be adjusted by the cooperation of the motor 12 and the threaded rod 3 installed on the slide groove 12, so that the clamping mechanism 4 can fix crankshafts of different lengths. The movement of the mobile frame 5 can be realized by the cooperation of the motor 12 and the threaded rod 3 installed on the slide groove 13. The movement of the drilling mechanism 6 can be realized by the cooperation of the motor 12 and the slide groove 13 installed on the mobile frame 5. By moving the mobile frame 5 and the drilling mechanism 6, the device can drill holes at various positions of the crankshaft. The mobile frame 5 is moved by the synchronous rotation of the two slide grooves 13, which can ensure that the mobile frame 5 is moved. The stability during the movement process, the rotating mechanism 8 installed on the clamping mechanism 4 can rotate the crankshaft fixed on the clamping mechanism 4, so as to realize the drilling of various positions on the surface of the crankshaft, the rotating mechanism 8 installed on the drilling mechanism 6 can adjust the inclination angle of the drilling mechanism 6, so that the device can drill inclined holes on the surface of the crankshaft, the fixing mechanism 7 can fix the crankshaft during the drilling process of the device, and prevent the crankshaft from rotating during the drilling process of the device, resulting in the device being unable to accurately drill holes on the crankshaft, the number of fixing mechanisms 7 installed on the orifice plate 11 corresponds to the number of connecting shafts of the crankshaft, to ensure the fixing effect of the fixing mechanism 7.
[0021] Specifically, the drilling mechanism 6 includes a slider 61, an electric telescopic rod 1 62, a mounting block 63, an electric telescopic rod 2 64, a fixing ring 65, a motor 2 66, a drill 67 and a mounting frame 68. The slider 61 is slidably mounted on the groove of the mobile frame 5. The electric telescopic rod 1 62 is mounted on the bottom surface of the slider 61.

When the device is drilling, the tip of the drill 67 can be moved to the surface close to the position to be drilled on the crankshaft by controlling the length of the electric telescopic rod 1 62, and the motor 2 66 is started to drive the drill 67 to rotate. At this time, the electric telescopic rod 2 64 is controlled to extend, and the drill 67 will drill the required hole on the surface of the crankshaft. The position of the drill 67 is adjusted by the cooperation of the electric telescopic rod 1 62 and the electric telescopic rod 2 64 to avoid the stability of the drilling mechanism 6 being affected during drilling when the position of the drill 67 is adjusted only by the electric telescopic rod 1 62, resulting in the drilling accuracy of the device being affected. The rotating mechanism 8 can adjust the inclination angle of the drill 67, so that the device can drill an inclined hole on the surface of the crankshaft.
[0023] Specifically, a protrusion is provided on the side wall of the slider 61, a groove matching the protrusion of the slider 61 is provided on the side wall of the groove of the movable frame 5, a symmetrical support rod penetrating the slider 61 is provided on the top surface of the mounting block 63, a fixing ring 65 whose center overlaps with the center of the rotating shaft is provided on the outer side of the rotating shaft of the electric telescopic rod 2 64, a support rod with a side wall protrusion is provided on the top surface of the mounting frame 68, and a groove matching the side wall protrusion of the support rod of the mounting frame 68 is provided on the side wall of the main body of the electric telescopic rod 2 64.
[0024] The cooperation between the side wall protrusions of the slider 61 and the side wall grooves on the groove of the moving frame 5 can ensure the stability of the slider 61 during movement. The support rod of the mounting block 63 is slidably mounted on the slider 61 to ensure the stability of the mounting block 63 during the extension and retraction of the electric telescopic rod 1 62. During the drilling process of the drill 67, the support rod of the mounting block 63 can also ensure the stability of the mounting block 63. The fixing ring 65 is rotatably mounted on the side wall of the bottom surface groove of the mounting block 63. The installation position of the fixing ring 65 ensures that the fixing ring 65 does not affect the rotation of the electric telescopic rod 2 64. The fixing ring 65 can ensure the stability of the electric telescopic rod 2 64 during rotation. The cooperation between the side wall protrusions of the support rod of the mounting frame 68 and the side wall grooves of the electric telescopic rod 2 64 can ensure the stability of the mounting frame 68 during movement and drilling.
[0025] Specifically, the clamping mechanism 4 includes a moving block 41, a rotating frame 42 and a mounting ring 43. One moving block 41 is fixed on the side wall of the slide groove 12, and the other moving block 41 is installed on the threaded rod 3 of the slide groove 12 through a thread. The moving block 41 installed on the threaded rod 3 is penetrated by the orifice plate 11 and then slidably installed on the orifice plate 11. The rotating frame 42 is rotatably installed on the opposite surface of the slide groove 12. The mounting ring 43 is installed on the rotating frame 42 through the protrusion on the side wall, and the rotating mechanism 8 is installed on the rotating frame 42 installed on the fixed moving block 41.
[0026] The mounting ring 43 is used to mount the two ends of the crankshaft. The inner wall of the rotating frame 42 is provided with a groove that matches the protrusion on the outer wall of the mounting ring 43. The cooperation between the protrusion and the groove can ensure the stability of the mounting ring 43 after being installed on the rotating frame 42. The rotating frame 42 is connected to the rotating mechanism 8. When the rotating mechanism 8 rotates with the rotating frame 42, the mounting ring 43 installed on the crankshaft will drive the crankshaft to rotate, which is convenient for the user to adjust the position of the crankshaft. The movement of the slidingly installed moving block 41 can be achieved through the cooperation of the threaded rod 3 installed on the slide groove 12 and the sliding moving block 41, so as to adjust the distance between the moving blocks 41, so as to ensure that the clamping mechanism 4 can fix crankshafts of different lengths. The orifice plate 11 can ensure the stability of the moving block 41 during the movement process. By selecting mounting rings 43 of different sizes, it can be ensured that the clamping mechanism 4 can fix crankshafts of different diameters.
[0027] Specifically, the rotating mechanism 8 includes a motor three 81, a pinion 82, a large gear 83 and a sleeve 84.

The sleeve 84 is installed on the rotating shaft of the rotatable parts in the clamping mechanism 4 and the drilling mechanism 6. The motor three 81 is provided with a power-off brake.
[0028] The power-off brake can ensure that the extending shaft of the motor three 81 will not rotate after the motor three 81 stops running, thereby ensuring the stability of the mounting ring 43 and the electric telescopic rod two 64. The power of the motor three 81 can be transmitted to the sleeve 84 through the cooperation of the small gear 82 and the large gear 83. The sleeve 84 is respectively installed on the rotating shaft of the rotating frame 42 and the electric telescopic rod two 64, thereby realizing the adjustment of the inclination angle of the electric telescopic rod two 64 and the position of the crankshaft installed on the clamping mechanism 4 by the rotating mechanism 8. By driving the large gear 83 with the small gear 82, the accuracy of the rotating mechanism 8 in adjusting the inclination angle of the electric telescopic rod two 64 and the position of the crankshaft installed on the clamping mechanism 4 can be ensured, thereby ensuring the processing accuracy of the device.
[0029] Specifically, the fixing mechanism 7 includes an electric telescopic rod 3 71, a mounting seat 72 and a clamping block 73. The bottom surface of the mounting seat 72 is provided with several protrusions matching the holes of the orifice plate 11. The top surface of the mounting seat 72 is installed with the electric telescopic rod 3 71, and the clamping block 73 is installed on the telescopic end of the electric telescopic rod 3 71.
[0030] The height of the clamping block 73 can be adjusted by the electric telescopic rod 3 71 to ensure that no matter what height the connecting shaft of the crankshaft is at, the clamping block 73 can play a supporting and fixing role. The cross-sectional shape of the clamping block 73 is an arc with a notch facing upward, which ensures the fixing effect of the clamping block 73 while preventing the fixing mechanism 7 from affecting the drilling of the device. The cooperation between the bottom surface protrusion of the mounting seat 72 and the hole of the orifice plate 11 ensures that the user can fix the fixing mechanism 7 at the desired position.

When adjusting the position of the crankshaft, retract the electric telescopic rod 3 71 to release the fixation of the crankshaft by the fixing mechanism 7, start the motor 3 81 installed on the moving block 41, and transmit the power of the motor 3 81 to the sleeve 84 with the cooperation of the small gear 82 and the large gear 83, and rotate the rotating frame 42 through the sleeve 84 to adjust the position of the crankshaft, adjust the position of the fixing mechanism 7 so that the fixing mechanism 7 can continue to fix the crankshaft.
