Description

Technical Field

[0001] The invention relates to the technical field of drilling, in particular to an externally mounted positioning drilling device for machining an automobile oil pan. Background Art

[0002] The automobile oil pan is an important part of the engine lubrication system. It is located at the bottom of the engine, like a container, and its main function is to store engine oil. Engine oil plays a vital role in the operation of the engine, such as lubrication, cooling, sealing and cleaning. The oil pan is generally disc-shaped and connected to the bottom of the engine cylinder by bolts to form a relatively closed space to store engine oil. There are usually two types of materials for the oil pan. One is stamped steel plate, which has low cost, good strength, and is easy to process and form. It is widely used in ordinary family car engines. The other is aluminum alloy. The aluminum alloy oil pan is lighter and has better heat dissipation performance than stamped steel plate. It is used in some high-performance engines or vehicles that are more sensitive to weight, because the lighter oil pan can reduce the overall weight of the vehicle, which helps to improve the vehicle's handling performance and fuel economy. When processing the automobile oil pan, it needs to be punched, so punching equipment is needed.

[0003] At present, the traditional punching device is easily affected by the vibration during the operation, which causes the punching tool to shake, and the overall equipment operation is not stable enough, resulting in inaccurate punching, affecting the overall punching quality.

[0033] As the moving module 44 drives the punch 45 to move toward the side close to the fixed module 52, the position of the punch 45 corresponds to the position of the circular hole 54, so that when the punch 45 punches a hole at the edge of the automobile oil pan blank, the punch 45 impacts the debris into the circular hole 54, not only performing the punching work but also discharging the debris in time.

[0034] The pushing assembly 56 includes a square supporting plate 561, which is fixedly installed at the side of the top of the fixed module 52 by screws, and a connecting shaft 562 is rotatably installed on the top of the square supporting plate 561, and a circular wheel 563 is fixedly installed on the outer side of the connecting shaft 562 and close to the guide bar 46, and a cylinder 564 is fixedly installed on the outer side of the circular wheel 563 and close to the semicircular protrusion 47, and a torque spring 565 is fixedly installed between the end of the connecting shaft 562 away from the circular wheel 563 and the square supporting plate 561, and a circular groove 566 is provided in the middle of the outer cylindrical surface of the cylinder 564, and a frame 567 is fixedly installed on the top of the outer cylindrical surface of the circular wheel 563, and a material pushing cone 568 is fixedly installed in the middle of the top of the frame 567. In the original state, the frame 567 is in a vertical state, and the material pushing cone 568 is at the top of the frame 567. After the punch 45 has completed punching the automobile oil pan blank, the movable module 44 can be driven to move to the side away from the fixed module 52 by the contraction of the telescopic end of the hydraulic cylinder 42, so that the punch 45 can be pulled out of the circular hole 54, and the slider 43 drives the guide bar 46 to move together, and the semicircular protrusions 47 evenly installed on the top of the guide bar 46 are engaged with the circular groove 566, so that the cylinder 564 is subjected to a pulling force in the circumferential direction, and under the rotation support of the connecting shaft 562, the circular wheel 563 drives the frame 567 to rotate counterclockwise, and the torque spring 565 is subjected to the torque force to elastically deform, and the frame 567 rotates counterclockwise, so that the ejector cone 568 is driven to rotate together, and the ejector cone 568 enters the inside of the tapered hole 55, so that the ejector force can be applied to the automobile oil pan in the cavity 53, and the automobile oil pan can be unloaded; When it is necessary to punch a new automobile oil pan blank again, the movable module 44 and the slider 43 are moved together, so that the guide bar 46 drives the semicircular protrusion block 47 to move in the opposite direction, and the cooperation between the semicircular protrusion block 47 and the circular groove 566 can be utilized again, so that the circular wheel 563 drives the frame 567 to rotate clockwise for reset.

[0039] The automobile oil pan discharged from the cavity 53 enters the interior of the receiving hopper 62 under the guidance of the guide plate 64, and makes the automobile oil pan contact with the flexible extension edge 66. The flexibility of the flexible extension edge 66 can weaken the impact force on the automobile oil pan, thereby protecting the automobile oil pan and facilitating the automobile oil pan to be discharged from the discharge port at the bottom of the receiving hopper 62.

The flexibility of the flexible extension edge 66 weakens the impact force on the automobile oil pan, thereby protecting the automobile oil pan and facilitating the automobile oil pan to be discharged from the discharge port at the bottom of the receiving hopper 62. When it is necessary to punch holes on a new automobile oil pan blank again, the movable module 44 and the slider 43 are moved together, so that the guide bar 46 drives the semicircular protrusion block 47 to move in the opposite direction, and the cooperation between the semicircular protrusion block 47 and the circular groove 566 can be utilized again, so that the circular wheel 563 drives the frame 567 to rotate clockwise for reset, and the above action can be repeated for batch punching.
