[0025] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a drilling device for manufacturing automotive engine shaft components, such as... Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the drilling device for manufacturing automotive engine shaft parts includes a drilling table 1, a support plate 2 fixedly mounted on the drilling table 1, a top plate 3 fixedly mounted on the support plate 2, a drilling head 4 disposed above the drilling table 1, a fixed upright plate 5 fixedly mounted on the drilling table 1, a slide groove 6 formed on the drilling table 1, a movable upright plate 7 slidably mounted inside the slide groove 6, and an inner support mechanism disposed on one side of the fixed upright plate 5 and the movable upright plate 7 for fixing the parts.

[0027] The internal support mechanism includes a fixed sleeve 8 fixedly installed inside the fixed upright plate 5 and the movable upright plate 7, a first threaded rod 9 rotatably installed inside the fixed sleeve 8, a handwheel 10 fixedly installed on the first threaded rod 9, a movable sleeve 11 screwed onto the first threaded rod 9, a fixed block 12 fixedly installed on the fixed sleeve 8 and the movable sleeve 11, a rotating rod 13 rotatably installed on both sides of the fixed block 12, and an internal support plate 14 provided on the side surface of the first threaded rod 9.

[0028] The movable sleeve 11 has a threaded hole inside that matches the first threaded rod 9. The end of the rotating rod 13 away from the fixed block 12 is rotatably connected to one side of the inner support plate 14. Multiple fixed blocks 12 are provided, and the fixed blocks 12 are arranged in a ring array on the fixed sleeve 8 and the movable sleeve 11.

[0029] When using this drilling device for manufacturing automotive engine shaft components, which include crankshafts, camshafts, balance shafts, drive shafts, and intermediate shafts, the process is as follows: First, the drilling table 1 is placed in a suitable position. Then, one end of the drive shaft is inserted into the side surface of the first threaded rod 9 on the fixed plate 5. Next, the movable plate 7 is pushed along the slide groove 6 until it is fitted with the drive shaft. The other end of the drive shaft is then inserted into the side surface of the first threaded rod 9 on the movable plate 7. Afterward, the handwheel 10 is turned, causing the first threaded rod 9, which is fixedly connected to it, to rotate synchronously. The movable sleeve 11 screwed onto it moves along the first threaded rod 9. The movement of the first threaded rod 9 drives the multiple fixed blocks 12 fixedly connected to it to move synchronously. At this time, the rotating rod 13 rotates around the position rotatably connected to the fixed block 12 as the center. The rotation of the rotating rod 13 drives the multiple inner support plates 14 to move outward until they fit against the inner wall of the drive shaft, thus completing the fixation of the drive shaft. At this time, the drive shaft is drilled by the drilling head 4. When it is necessary to remove the drive shaft, simply turn the handwheel 10 in the opposite direction to stop the limit on the drive shaft. At this time, the drive shaft can be removed, reducing the damage to the anti-rust coating on the surface of the parts caused by clamping and improving the quality of the parts.

[0030] Furthermore, to facilitate the forward and backward movement of the punch head 4 for punching the drive shaft, such as... Figure 1 , Figure 2 and Figure 5 As shown, a fixed frame 15 is movably connected to the bottom of the top plate 3, a second threaded rod 16 is rotatably connected inside the fixed frame 15, and a limit rod 17 is fixedly connected inside the fixed frame 15.

[0031] The second threaded rod 16 has a sliding plate 18 screwed onto its side surface. The sliding plate 18 has a threaded hole that matches the second threaded rod 16. The limiting rod 17 passes through the sliding plate 18. The bottom of the sliding plate 18 is fixedly connected to the top of the punch head 4.

[0032] When using this drilling device for manufacturing automotive engine shaft parts, after the drive shaft is fixed by the internal support mechanism, the external motor is started. The output shaft of the motor drives the second threaded rod 16 to rotate synchronously. Through the rotation of the second threaded rod 16 and the cooperation between the two limit rods 17, the slide plate 18 moves along the limit rods 17. The movement of the slide plate 18 drives the drilling head 4, which is fixedly connected to it, to move synchronously, thereby realizing drilling at various positions of the drive shaft.

[0033] It should be noted that, in order to facilitate the left and right movement of the punch head 4 for punching the drive shaft, as follows: Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a stand 19 is fixedly connected to the top of the fixed frame 15, a drive wheel 21 is rotatably connected inside the stand 19, and a rotating wheel 20 is rotatably connected to the top of the fixed frame 15.

[0034] The top plate 3 has a movable groove 22 inside, and the drive wheel 21 and the rotating wheel 20 are both located inside the movable groove 22.

[0035] When the drilling device for manufacturing automotive engine shaft parts is in use, after the drive shaft is fixed by the internal support mechanism, the external motor is started. The output shaft of the motor drives the drive wheel 21, which is fixedly connected to it, to rotate synchronously. Through the rotation of the drive wheel 21 and the cooperation between the rotating wheel 20, the entire fixed frame 15 moves left and right along the top plate 3. Through the cooperation with the second threaded rod 16, the drilling head 4 moves back and forth and left and right.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
