Description

Technical Field

[0001] The utility model relates to the technical field of drilling equipment, and more specifically to a mechanical accessory drilling equipment. Background Art

[0002] In the engine system, in order to balance the unevenness of the crankshaft during engine operation, the existing engine flywheel is generally designed and installed at the rear end of the engine. During the production process of the flywheel, it is necessary to process mounting holes and heat dissipation holes on the flywheel to achieve the positioning installation of the flywheel and weight reduction and heat dissipation.

[0003] The existing publication number is CN108526526B, and the patent name is a patent document of a mechanical accessory drilling device. It discloses that a through hole is opened in the middle of the drilling machine for an electric push rod to pass through and engage. The electric push rod will swing up and down. However, because the inclination angle of the drilling machine needs to be adjusted, the drilling machine needs to be flexibly connected and there is an assembly gap. When drilling holes, the drill bit will vibrate due to the loose fixation of the drilling machine, affecting the drilling accuracy and even causing damage to the drill bit. In view of this, we propose a mechanical accessory drilling device. Utility Model Content

[0027] Example:

[0028] This embodiment provides an angle adjustment device, which is specially used to adjust the drilling angle of a mechanical accessory drilling device. Figure 1 , including a drilling machine 1, the drilling machine 1 is an electric drilling machine for drilling, and two connecting sleeves 5 are installed on the drilling machine 1 in parallel on the left and right. The connecting sleeve 5 is used as a connecting piece for installing a connecting frame 3. The lower part of the connecting sleeve 5 is hinged with the connecting frame 3. The connecting frame 3 and the drilling machine 1 can be rotatably connected by hinged means. A telescopic cylinder 2 is installed at the bottom of the connecting frame 3 on the left side. The telescopic cylinder 2 is an electro-hydraulic push rod. When drilling is required, the telescopic cylinder 2 is shortened to press the drilling machine 1 downward to drill the flying disc. After the drilling is completed, the telescopic cylinder 2 is extended to push the left end of the drilling machine 1 Lift it up to make the telescopic cylinder 2 avoid the flying disc and prevent wear. A fixing frame 4 is installed at the bottom of the connecting frame 3 on the right side. The fixing frame 4 can fix the connecting frame 3 on the right. At this time, the connecting frame 3 on the left side moves up and down, so as to realize the swing adjustment angle of the drilling rig 1. When the telescopic cylinder 2 is shortened, the connecting frame 3 and the connecting sleeve 5 are pressed and contacted. At this time, the connecting frame 3 and the connecting sleeve 5 are pressed against each other to offset the assembly gap between the connecting frame 3 and the connecting sleeve 5, realize the rigid connection between the connecting frame 3 and the connecting sleeve 5, stably fix the drilling rig 1, and ensure the stable position of the drilling rig 1 when drilling.

[0029] In a further embodiment, referring to Figure 2The connecting sleeve 5 includes an annular main body 51, which is sleeved on the outside of the drilling rig 1 to adapt to the cylindrical shape of the drilling rig 1 to ensure stable connection. Pins are installed on the front and rear side walls of the main body 51, and the pins extend forward and backward for rotationally connecting the connecting frame 3. A support ear 52 is provided at the lower left part of the main body 51, and the support ear 52 extends to the left. When the telescopic cylinder 2 is shortened, the support ear 52 and the connecting frame 3 can be abutted against each other to avoid the drilling rig 1 directly squeezing the connecting frame 3, avoid deformation of the drilling rig 1, and ensure stable use of the drilling rig 1.

[0030] In a further embodiment, referring to Figure 2 The connecting frame 3 includes an arc frame 31, which is made of a hard material. The arc frame 31 is in a U-shaped setting with an opening upward and has two top ends. The top of the arc frame 31 is hinged with a pin rod. After the connection, a gap can be ensured between the arc frame 31 and the main body 51 to ensure that the drilling rig 1 can swing smoothly. A support block 32 that cooperates with the support ear 52 is installed in the middle of the arc frame 31. The support block 32 is installed in a position that contacts the support ear 52. The support block 32 is made of wear-resistant material to avoid rapid wear of the support block 32.

[0031] In a further embodiment, referring to Figure 3 A mounting groove 33 is provided at the lower part of the arc frame 31. The mounting groove 33 is directly provided in the middle part of the arc frame 31 and is integrally milled on the arc frame 31, which is convenient for production. The support block 32 is slidably installed in the middle part of the mounting groove 33 up and down. The support block 32 can be disassembled for easy replacement, and the support block 32 can be moved up and down. After wear, the position of the support block 32 can be adjusted to adapt to the thickness of the wear, thereby ensuring that the position of the drilling rig 1 is consistent after each adjustment and ensuring good consistency of drilling.

[0032] In a further embodiment, referring to Figure 3 The screw hole 34 is provided on the inner wall of the mounting groove 33, and the screw hole 34 is arranged horizontally. A connecting rod 35 is screwed and installed in the screw hole 34. A threaded end is provided at the right end of the connecting rod 35 for screwing with the screw hole 34, so that the connecting rod 35 is detachable and easy to replace the connecting rod 35. The outer wall in the middle of the connecting rod 35 is arranged to be a smooth surface, and an adjusting member 36 is sleeved and installed on the outer side of the connecting rod 35. The adjusting member 36 is sleeved on the smooth surface of the connecting rod 35, which can ensure that the contact area between the connecting rod 35 and the inner wall of the adjusting member 36 is large, and the position of the adjusting member 36 is stable. An eccentric block is provided at one end of the adjusting member 36 near the support block 32, and the eccentric block can be rotated to realize that different positions of the eccentric block contact the bottom surface of the support block 32, thereby adjusting the height of the support block 32. A nut is provided at the end of the connecting rod 35 after adjustment. The nut can squeeze and fix the support block 32 and the adjusting member 36 to achieve stable position of the adjusting member 36 and the support block 32, and avoid changes in the position of the support block 32 during use.

[0033] In a further embodiment, referring to Figure 4A hexagonal sleeve is provided at one end of the adjusting member 36 away from the threaded hole 34. To facilitate the position adjustment of the adjusting member 36, a tool can be used in conjunction with the hexagonal sleeve to adjust the position of the eccentric block, which is convenient for adjustment. The hexagonal sleeve is provided on the outside of the connecting rod 35, and the hexagonal sleeve serves as a sleeve to increase the contact area with the connecting rod 35, thereby ensuring the stability of the position of the adjusting member 36, and can be directly pulled out to the left to replace the support block 32, which is convenient for maintenance.

[0034] In a further embodiment, referring to Figure 4 The bottom of the support block 32 is provided with an arc groove 37 that cooperates with the eccentric block. When the eccentric block rotates, the arc groove 37 can contact the eccentric block. The arc groove 37 is arc-shaped to achieve stable contact. The lower part of the support block 32 is provided with a through hole 38 for the hexagonal sleeve and the connecting rod 35 to pass through. The through hole 38 has a large vertical length, so that the support block 32 can move up and down smoothly, and when adjusting the position of the support block 32, the front and rear inner walls of the through hole 38 slide in contact with the front and rear outer walls of the hexagonal sleeve and the connecting rod 35, and the front and rear outer walls of the support block 32 slide in contact with the front and rear inner walls of the mounting groove 33 to prevent the mounting groove 33 from tilting.
