Description

Technical Field

[0001] This utility model relates to the field of boring machine technology, and in particular to a boring machine for machining piston holes. Background Technology

[0002] Piston bore machining is a critical process in the manufacturing and repair of internal combustion engines. It primarily involves precisely boring pin holes on the piston body to ensure the assembly accuracy and operational stability between the piston and connecting rod. As one of the most precise machined parts in the piston assembly, the dimensional accuracy, form and position tolerances, and surface roughness of the piston bore have a decisive impact on the overall engine performance, power output, and service life. The boring machine, as the core equipment for this process, directly determines the machining quality and production efficiency of the piston bore through its structural design, machining accuracy, and auxiliary functions.

[0003] A boring machine for machining piston bores plays a crucial role in piston manufacturing. As a key piece of equipment for piston bore forming, its machining methods and supporting functions have a decisive impact on overall machining accuracy and production efficiency. Especially in the core boring process, existing boring machine equipment has gradually revealed a series of obvious limitations and technical problems when processing piston components made of high-precision, high-strength materials. Utility model patent CN216065660U discloses a combination boring machine for machining piston pin holes, including a worktable, a support plate on the worktable, a first motor on the support plate, a fixed platform connected to the first motor via a rotating shaft, a cover on the fixed platform, telescopic cylinders on both sides of the fixed platform located on the rotating shaft, a fixing hole matching the shape of the telescopic cylinder on the side of the fixed platform connected to the rotating shaft, lead screw slides mirrored on both sides of the fixed platform located on the worktable, an electric telescopic rod connected to the lead screw slides via a slider, a protective shell connected to the top of the electric telescopic rod, a drive shaft inside the protective shell, a drill bit on one end of the drive shaft near the fixed platform, a second motor on the other end of the drive shaft, and cylindrical internal drilling tools and truncated conical internal drilling tools respectively fixed on the drill bits on both sides of the fixed platform.

[0004] While this solution improves the convenience and efficiency of piston pin hole machining through combined cutting tools, it still has significant shortcomings in practical applications. Specifically, existing boring machines are not adept at effectively cleaning machining debris and residual impurities during piston hole machining. This leads to debris accumulation on the workpiece surface or inside the machine tool, affecting the accuracy and efficiency of subsequent machining and potentially scratching the machined surface, causing secondary contamination or quality defects. Furthermore, the lack of an effective chip removal and cleaning mechanism requires operators to frequently stop the machine for manual cleaning, increasing labor intensity and reducing automation. To address these shortcomings, we urgently need an innovative boring machine for piston hole machining. Utility Model Content

[0005] The purpose of this invention is to provide a boring machine for machining piston holes, which solves the problem that existing boring machines are not convenient for effectively cleaning the machining debris and residual impurities generated when machining piston holes, resulting in debris accumulation on the workpiece surface or inside the machine tool. This not only affects the accuracy and efficiency of subsequent machining, but may also scratch the machined surface, causing secondary pollution or quality defects.

[0006] To achieve the above objectives, this utility model provides a boring machine for machining piston holes, including a base, with the boring machine mounted on one side of the top of the base, and a support frame fixedly connected to one side of the boring machine, with a cleaning frame slidably connected to the inner side of the support frame.

[0021] 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.

[0022] Please see Figure 1-5 A boring machine for machining piston holes includes a base 1, with a boring machine 2 mounted on one side of the top of the base 1. A support frame 19 is fixedly connected to one side of the boring machine 2, and a cleaning frame 13 is slidably connected to the inner side of the support frame 19. A cleaning roller 14 is rotatably connected to the inner side of the cleaning frame 13, and a second motor 15 is bolted to one side of the outer wall of the cleaning frame 13. One end of the cleaning roller 14 passes through the side wall of the cleaning frame 13 and is connected to the output shaft of the second motor 15. A side frame 4 is fixedly connected to one side of the top of the support frame 19, and a first motor 8 is bolted to one side of the outer wall of the side frame 4. A screw 6 is rotatably connected to the inner side of the side frame 4, with one end of the screw 6 passing through the side wall of the side frame 4 and connected to the output shaft of the first motor 8. A nut seat 7 is threadedly connected to one end of the screw 6, and the bottom of the nut seat 7 is fixedly connected to the top of the cleaning frame 13. Grooves 20 are provided on both sides of the support frame 19.

[0023] First, the piston workpiece to be processed is fixed in the working area of ​​the boring machine 2. Then, the boring machine 2 is started to perform normal boring operations, cutting the pin hole on the piston body with high precision. During the processing, a large amount of metal chips and residual impurities are generated. If these chips are not cleaned in time, they can easily accumulate inside the machine tool or on the surface of the workpiece, affecting the quality and efficiency of subsequent processing. To solve this problem, when a single processing is completed or the predetermined cleaning time point is reached, the operator can activate the cleaning device set in the support frame 19 on one side of the boring machine 2. Specifically, the first motor 8 is started first, and its output shaft drives the screw 6 to rotate. Through the cooperation of the screw 6, the cleaning device is activated. The nut seat 7 moves linearly, causing the cleaning frame 13 connected to its top to slide along the inner side of the support frame 19, thereby covering the area to be cleaned. At the same time, the second motor 15 starts, and its output shaft drives the cleaning roller 14 to rotate, so that the cleaning roller 14 continuously cleans the debris in the support frame 19 as it moves with the cleaning frame 13. Under the action of centrifugal force and gravity, the debris is detached from the cleaning roller 14 and falls into the troughs 20 opened on both sides of the support frame 19, and is finally discharged to the outside of the machine tool. The entire cleaning process does not require machine shutdown or manual intervention, realizing the automatic collection and removal of processing debris, and ensuring the continuous and stable operation of the equipment.

[0024] Furthermore, a support frame 3 is fixedly connected to the top of the support frame 19, and a rotating rod 9 is rotatably connected to one side of the inner side of the support frame 3. A fan 10 is fixedly connected to one end of the rotating rod 9, and the other end of the rotating rod 9 is connected to one end of the screw 6 by a belt 12. When the first motor 8 drives the screw 6 to rotate, power is transmitted to the rotating rod 9 through the pulley 11 and the belt 12, causing the fan 10 to rotate synchronously. This design generates airflow while cleaning debris, helping to blow lightweight debris towards the trough 20, further improving cleaning efficiency and effectiveness.

[0025] Furthermore, one end of the screw 6 is rotatably connected to the inner wall of the side frame 4 via a rotating shaft, and the other end of the screw 6 passes through the side wall of the side frame 4 via a bearing sleeve. One end of the rotating rod 9 passes through the side wall of the bearing frame 3 via a bearing sleeve. Both the rotating rod 9 and the screw 6 are fitted with pulleys 11, and the two pulleys 11 are connected by a belt 12, which ensures the smoothness and reliability of the transmission process, reduces mechanical wear, extends the service life of the equipment, and realizes the function of synchronous movement of the fan 10 and the cleaning frame 13, improving the working coordination of the entire device.

[0026] Furthermore, a side plate 5 is fixedly connected to one side of the support frame 19, and a slider 16 is fixedly connected to one side of the cleaning frame 13. The slider 16 is slidably connected to the side plate 5 through the slide groove 17, which makes the cleaning frame 13 more stable and smooth when sliding along the inner side of the support frame 19, avoiding the problem of incomplete cleaning caused by shaking or deviation, and enhancing the accuracy and consistency of the cleaning operation.

[0027] Furthermore, one end of the cleaning roller 14 is rotatably connected to the inner wall of the cleaning frame 13 via a rotating shaft, and the other end of the cleaning roller 14 passes through the side wall of the cleaning frame 13 via a bearing sleeve, ensuring that the cleaning roller 14 can rotate smoothly and efficiently remove the debris attached to the inner side of the support frame 19 under the drive of the second motor 15. This prevents the motor load from increasing or being damaged due to excessive friction, and also ensures the continuity and stability of the cleaning work.

[0028] Furthermore, collection frames 18 are fixedly connected to the top of the base 1 on one side near each of the two drains 20, facilitating centralized processing and recycling. This not only maintains a clean working environment but also reduces the impact on subsequent processing, improving the overall safety and environmental friendliness of production. In addition, this design simplifies post-cleaning maintenance, reduces labor costs, and enhances the convenience and economy of equipment use.

[0029] In summary:

[0030] First, the piston workpiece to be processed is fixed in the working area of ​​the boring machine 2 mounted on one side of the top of the base 1. Then, the boring machine 2 is started to perform normal boring operations, cutting the pin hole on the piston body with high precision. During the processing, a large amount of metal chips and residual impurities are generated. If these chips are not cleaned in time, they can easily accumulate inside the machine tool or on the surface of the workpiece, affecting the quality and efficiency of subsequent processing. To solve this problem, when a single processing is completed or the predetermined cleaning time point is reached, the operator can activate the automatic cleaning device set in the support frame 19 on one side of the boring machine 2. Specifically, the first motor 8, which is fixed to the outer wall of the side frame 4 by bolts, is first started. Its output shaft drives the screw 6 to rotate. One end of the screw 6 is rotatably connected to the inner wall of the side frame 4 through a rotating shaft, and the other end passes through the side wall of the side frame 4 through a bearing sleeve to ensure smooth and reliable transmission. At the same time, one end of the screw 6 transmits power to the rotating rod 9 rotatably connected to the inner side of the support frame 3 through the pulley 11 and the wound belt 12, thereby driving the fan 10 to rotate synchronously and generate airflow. As the screw 6 rotates, the nut seat 7, which is threadedly connected to it, moves linearly, causing the cleaning frame 13, which is fixedly connected to its top, to slide along the inner side of the support frame 19. A sliding connection is formed between the side plate 5, which is fixedly connected to the side of the support frame 19 via a sliding groove 17, through a slider 16 fixedly connected to one side of the cleaning frame 13. This ensures the stability and smoothness of the cleaning frame 13 during movement, preventing incomplete cleaning due to shaking. Simultaneously, a second motor 15 is bolted to one side of the outer wall of the cleaning frame 13. Its output shaft drives the cleaning roller 14 to rotate. One end of the cleaning roller 14 is rotatably connected to the inner wall of the cleaning frame 13 via a rotating shaft, while the other end passes through the side wall of the cleaning frame 13 via a bearing sleeve, ensuring smooth rotation and stable operation. As the cleaning roller 14 moves with the cleaning frame 13, it continuously cleans the debris inside the support frame 19. Simultaneously, the airflow generated by the fan 10 blows lightweight debris towards the drainage grooves 20 on both sides of the support frame 19, making it easier for the debris to be discharged.The debris ultimately falls from the trough 20 into the collection frame 18 fixed near its sides at the top of the base 1, facilitating centralized processing and recycling. Through the coordinated arrangement of the first motor 8, screw 6, nut seat 7, and cleaning frame 13, the cleaning frame 13 achieves automatic reciprocating movement along the support frame 19, covering the entire area to be cleaned without manual intervention, significantly improving automation and cleaning efficiency. Secondly, the second motor 15 drives the cleaning roller 14 to rotate, effectively removing metal debris adhering to the inner wall of the support frame 19 under centrifugal force and mechanical contact, preventing debris accumulation from affecting subsequent processing accuracy. Thirdly, the fan 10, linked to the screw 6 via the belt 12, generates auxiliary airflow during the cleaning process, further enhancing the removal of debris. The cleaning frame 13 has excellent chip removal and dispersion capabilities, making it particularly suitable for removing fine particles and dust. Fourth, the design of the slider 16 and chute 17 makes the cleaning frame 13 more stable during movement, improving the precision and consistency of cleaning actions and avoiding cleaning dead zones caused by deviation. Fifth, the trough 20 combined with the collection frame 18 not only improves the chip removal efficiency but also achieves centralized collection and environmentally friendly treatment of chips, reducing environmental pollution and improving the cleanliness of the production site. Sixth, the entire transmission system uses pulleys 11, belts 12, and bearing sleeves, effectively reducing operating noise and mechanical wear, extending the equipment's service life, and ensuring coordinated movement between components and overall operational reliability.
