Technical Field
[0001] This utility model relates to the field of cylinder head processing technology, and in particular to a drilling machine for forming oblique oil holes in motorcycle cylinder heads. Background Technology
[0002] The drilling machine for forming oblique oil holes in motorcycle cylinder heads plays a vital role in the motorcycle manufacturing industry. As a key step in engine component processing, its performance has a decisive impact on the overall operating efficiency and safety of motorcycles. Especially in the core process of drilling oblique oil holes in motorcycle cylinder heads, existing drilling equipment and technologies have gradually revealed a series of obvious limitations and technical problems when dealing with cylinder heads of specific shapes and requirements.
[0003] Specifically, existing motorcycle cylinder head inclined oil hole forming drilling machines, such as the inclined cylinder joint oil hole drilling tool disclosed in utility model patent CN207788322U, have replaced manual positioning and clamping functions, thus avoiding the drawbacks of low positioning accuracy, unreliable clamping and poor operation safety of manual positioning.
[0004] However, existing motorcycle cylinder head inclined oil hole forming drilling machines are not convenient for flexible adjustment of the drilling position. This means that when dealing with motorcycle cylinder heads of different models or design requirements, it is necessary to frequently change fixtures or adjust machine parameters. This not only increases production preparation time but also significantly reduces drilling efficiency and flexibility. Furthermore, due to the inability to flexibly adjust the drilling position, traditional drilling equipment struggles to guarantee drilling accuracy for some complex structures or inclined oil holes with special angles, leading to unstable product quality, increased scrap rate, and higher production costs. These problems directly result in reduced production efficiency, increased operational complexity, and difficulty in meeting diverse and high-precision production demands. Therefore, to address the numerous shortcomings of existing technologies, we urgently need an innovative motorcycle cylinder head inclined oil hole forming drilling machine to solve these problems.

Detailed Implementation
[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0023] Please see Figure 1-5A drilling machine for forming inclined oil holes in a motorcycle cylinder head includes a frame 1, a support plate 11 slidably connected to the lower inner side of the frame 1, a top frame 2 fixedly connected to the top of the frame 1, and a support frame 6 provided on the upper inner side of the frame 1; a screw 3 is rotatably connected to the inner side of the top frame 2, and one end of the screw 3 is threadedly connected to a nut seat 4, with the bottom of the nut seat 4 fixedly connected to the top of the support frame 6; a fixed frame 18 is slidably connected to the inner side of the support frame 6, and the inner side of the fixed frame 18... A second motor 19 is fixedly connected by bolts, and a rotating rod 10 is rotatably connected to the bottom of the fixed frame 18. A drill bit 9 is fixedly connected to the bottom end of the rotating rod 10, and the top end of the rotating rod 10 passes through the bottom of the fixed frame 18 and is connected to the output shaft of the second motor 19. A clamping frame 14 is fixedly connected to the top of the bearing plate 11, and a hydraulic cylinder 17 is fixedly connected to the bottom of the frame 1 by bolts. The output shaft of the hydraulic cylinder 17 passes through the bottom of the frame 1 and is fixedly connected to the bottom of the bearing plate 11.
[0024] First, place the motorcycle cylinder head to be processed into the clamping frame 14, and ensure its secure fixation using the clamping assembly. Start the second motor 19, which rotates the drill bit 9 via the rotating rod 10, preparing for drilling. Depending on the required drilling position and angle, the lateral position of the drill bit 9 can be adjusted by rotating the screw 3, specifically by using the nut seat 4 to move the support frame 6; simultaneously, the second cylinder 20 pushes the fixed frame 18 to move, adjusting the longitudinal position of the drill bit 9. These adjustment mechanisms ensure that the drill bit 9 is accurately aligned with the drilling position. After all preset adjustments are completed, start the hydraulic cylinder 17, causing the support plate 11 to move up and down, thus moving the motorcycle cylinder head below the drill bit 9 for drilling.
[0025] Furthermore, clamping plates 15 are provided on both inner sides of the clamping frame 14, and first cylinders 16 are fixedly connected to both sides of the clamping frame 14 by bolts. The output shafts of the two first cylinders 16 pass through the side wall of the clamping frame 14 and are fixedly connected to one side of the two clamping plates 15 respectively. When the motorcycle cylinder head is placed in the clamping frame 14, the first cylinder 16 is activated, and its output shaft pushes the clamping plate 15 to move inward, thereby clamping and fixing the motorcycle cylinder head, achieving a stable clamping effect, ensuring that the motorcycle cylinder head will not shift during the drilling process, and improving processing accuracy and safety.
[0026] Furthermore, sliders 7 are fixedly connected to both sides of the fixed frame 18, and both sliders 7 are slidably connected to the side wall of the support frame 6 through the sliding groove 8. The fixed frame 18 achieves longitudinal sliding through the cooperation of the sliders 7 on both sides with the sliding groove 8 of the support frame 6. When the second cylinder 20 pushes the sliders 7, the fixed frame 18 can move smoothly along the sliding groove 8, thereby driving the drill bit 9 to adjust its longitudinal position, achieving the effect of accurately adjusting the longitudinal position of the drill bit 9, while avoiding drilling errors caused by shaking or offset.
[0027] Furthermore, two second cylinders 20 are fixedly connected to both sides of the support frame 6 by bolts, and the output shafts of the two second cylinders 20 pass through the side wall of the support frame 6 and are fixedly connected to one side of the two sliders 7 respectively. When the second cylinder 20 is activated, its output shaft pushes the slider 7 to move along the slide groove 8, thereby driving the fixed frame 18 and the drill bit 9 to adjust their positions precisely in the longitudinal direction. This achieves the effect of flexibly controlling the longitudinal movement of the drill bit 9, improving the equipment's adaptability to different drilling height requirements, and further enhancing the equipment's versatility and processing efficiency.
[0028] Furthermore, a first motor 5 is fixedly connected to one side of the outer wall of the top frame 2 by bolts. One end of the screw 3 is rotatably connected to the inner wall of the top frame 2, and the other end of the screw 3 is connected to the output shaft of the first motor 5 through a bearing sleeve through the side wall of the top frame 2. A protrusion 22 is fixedly connected to the top of the nut seat 4, and the protrusion 22 is slidably connected to the top of the top frame 2 through the movable groove 21. When the first motor 5 is started, the screw 3 is driven to rotate. The screw 3 drives the nut seat 4 to move through the thread engagement. At the same time, the protrusion 22 on the top of the nut seat 4 slides along the movable groove 21 of the top frame 2 to ensure the stability and accuracy of the lateral movement. This achieves the effect of quickly adjusting the lateral position of the drill bit 9, meets the multi-angle positioning requirements in the processing of complex inclined oil holes, and significantly improves the drilling flexibility and processing efficiency.
[0029] Furthermore, sliding blocks 12 are fixedly connected to both sides of the bearing plate 11, and both sliding blocks 12 are slidably connected to the inner wall of the frame 1 through sliding grooves 13. When the hydraulic cylinder 17 pushes the bearing plate 11 to move up and down, the sliding blocks 12 on both sides of the bearing plate 11 slide along the sliding grooves 13 on the inner wall of the frame 1, ensuring that the movement of the bearing plate 11 is smooth and without deviation, thereby improving the stability of the bearing plate 11 during the lifting process, avoiding processing errors caused by vibration or deviation, and further ensuring drilling quality and operational safety.
[0030] In summary:
[0031] First, the motorcycle cylinder head to be processed is placed in the clamping frame 14, and the clamping plate 15 is moved inward by the first cylinder 16 to ensure the motorcycle cylinder head is firmly fixed. The second motor 19 is started, and the drill bit 9 is rotated by the rotating rod 10 to prepare for drilling. According to the actual drilling position and angle requirements, the screw 3 is rotated by starting the first motor 5, and the nut seat 4 is moved laterally by the thread engagement; at the same time, the slider 7 is pushed by the second cylinder 20 to slide along the slide groove 8, thereby driving the fixed frame 18 and the drill bit 9 on it to adjust the position precisely in the longitudinal direction. These adjustment mechanisms ensure that the drill bit 9 can be accurately aligned with the drilling position. After all the preset adjustments are completed, the hydraulic cylinder 17 is started, so that the support plate 11 moves smoothly up and down along the sliding groove 13 in the frame 1 through the sliding blocks 12 on both sides, so that the motorcycle cylinder head is moved up to below the drill bit 9 for drilling. The clamping frame 14, the first cylinder 16, and the clamping plate 15 ensure stable clamping of the motorcycle cylinder head, preventing displacement during drilling and improving machining accuracy and safety. Secondly, the cooperation between the sliders 7 on both sides of the fixed frame 18 and the sliding grooves 8 of the support frame 6, along with the second cylinder 20, allows for precise longitudinal adjustment of the fixed frame 18 and the drill bit 9, preventing drilling errors caused by shaking or offset and enhancing the equipment's adaptability to different height requirements. Furthermore, the rotation of the screw 3 driven by the first motor 5 moves the nut seat 4, and combined with the design of the protrusion 22 and the movable groove 21, enables rapid lateral position adjustment of the drill bit 9, meeting the multi-angle positioning requirements in complex inclined oil hole machining and significantly improving drilling flexibility and processing efficiency. Finally, the cooperation between the sliding blocks 12 on both sides of the support plate 11 and the sliding grooves 13 on the inner wall of the frame 1 ensures stable lifting and lowering of the support plate 11 under the action of the hydraulic cylinder 17, preventing machining errors caused by vibration or deviation and further guaranteeing drilling quality and operational safety. In summary, this design not only solves the problem of difficulty in flexibly adjusting the drilling position in existing technologies, but also significantly improves production efficiency, product accuracy, and operational safety, making it particularly suitable for high-precision machining of inclined oil holes in motorcycle cylinder heads.
