Description

Technical Field

[0001] This invention relates to the field of machining technology, and in particular to a tooling for horizontal milling of cylinder heads. Background Technology

[0002] In modern mechanical manufacturing, the cylinder head, as a key component of the engine, directly affects the engine's performance and reliability due to its machining quality. With the rapid development of the automotive industry and other related sectors, higher demands are placed on the precision, surface quality, and production efficiency of the cylinder head. Traditional tooling presents several problems in the milling process of cylinder heads. Firstly, insufficient precision in positioning the cylinder head leads to deviations during milling, affecting machining accuracy and consequently reducing overall engine performance. For example, some tooling cannot effectively secure the cylinder head, potentially causing slight displacement during machining, resulting in dimensions that do not meet design requirements. Secondly, traditional tooling offers limited and inflexible milling head adjustment methods. It is difficult to quickly and accurately adjust the position and angle of the milling head to adapt to different machining needs, which not only prolongs preparation time but also reduces production efficiency. Furthermore, waste materials and coolant generated during machining cannot be effectively treated and recycled. Accumulated waste affects the machining environment and quality, while wasted coolant increases production costs. For example, some tooling lacks a proper waste discharge channel, which can easily clog the machining area and affect the normal operation of the milling head; coolant is often discharged directly without being recycled, resulting in a waste of resources.

[0003] Furthermore, as market demand for engine diversification continues to increase, the types and specifications of cylinder heads are also becoming increasingly numerous. Traditional tooling is struggling to adapt to these diverse processing requirements, necessitating frequent tooling changes, which further reduces production efficiency and increases production costs.

[0004] Therefore, in order to meet the requirements of modern manufacturing industry for high precision, high efficiency, low cost and environmental protection in cylinder head milling, there is an urgent need for a new type of tooling for horizontal milling of cylinder heads that can solve the problems of the above-mentioned traditional tooling and improve the processing quality and production efficiency of cylinder heads. Summary of the Invention

[0005] Purpose of the invention: The purpose of this invention is to provide a function that can improve the accuracy and quality of cylinder head milling; another purpose of this invention is to provide efficient treatment of waste materials and coolant and recycling of coolant, thereby improving the overall efficiency of the machining system.

[0006] Technical solution: A tooling for horizontal milling of cylinder heads includes a cavity, a groove on the upper surface of the cavity, multiple material leakage holes on the upper surface of the groove, a sliding groove on the right side of the upper surface of the cavity, a support plate slidably connected inside the sliding groove, a reduction motor fixedly connected to the upper surface of the support plate, a cylinder fixedly connected to the top of the output end of the reduction motor, the top of the cylinder extending through to the top of the sliding groove and fixedly connected to a horizontal plate, sliding grooves symmetrically formed on the outer side wall of the horizontal plate, a slide frame slidably connected to the outer side walls of the two sliding grooves, a slot fixedly connected to the lower surface of the slide frame, and a milling head engaged inside the slot.

[0007] Furthermore, a rotating column is rotatably connected to the inner side wall of the carriage, and a toothed rotating cylinder is fixedly connected to the outer side wall of the rotating column. A moving groove is formed on the lower surface of the cross plate, and a conveying tooth is formed on the lower surface of the moving groove. The toothed rotating cylinder is meshed with the conveying tooth. A motor is fixedly connected to the front surface of the carriage, and the output end of the motor passes through the interior of the carriage and is fixedly connected to the front end of the rotating column.

[0008] Furthermore, a perforated plate is symmetrically fixedly connected to the left side of the carriage, and a vertical column is rotatably connected inside the perforated plate. An extension rod is fixedly connected to the outer wall of the vertical column. A water storage chamber is fixedly connected to the left side of the cavity. An arc groove is formed on the upper surface of the water storage chamber. An extension cavity is formed on the left side of the upper surface of the water storage chamber. A sliding rod is slidably connected inside the extension cavity. The upper surface of the sliding rod is fixedly connected to the lower surface of the extension rod.

[0009] Furthermore, a pumping rod is fixedly connected to the lower right side of the extension rod, the bottom end of the pumping rod extends into the interior of the water storage chamber, and the outer side wall of the pumping rod contacts the inner side wall of the arc groove.

[0010] Furthermore, a load-bearing plate is fixedly connected to the right side of the cavity, and a control air pump is fixedly connected to the upper surface of the load-bearing plate. The output end of the control air pump is fixedly connected to the sliding groove.

[0011] Furthermore, the cavity is symmetrically provided with inclined plates inside, and screening grooves are fixedly connected between the inclined plates. The outer side walls of the screening grooves are symmetrically fixedly connected with leakage holes, and the inner side walls of the screening grooves are symmetrically provided with fine sieve holes.

[0012] Furthermore, the front surface of the cavity is provided with an outlet, and the inside of the outlet is connected to a material receiving chamber, the inner sidewall of which is provided with a coarse sieve hole.

[0013] Furthermore, the extension rod includes a long cavity, an extension crossbar is slidably connected inside the long cavity, a water outlet is opened inside the extension crossbar, a water pipe is fixedly connected between the long cavity and the pumping rod, and a pumping nozzle is fixedly connected to the lower surface of the extension crossbar.

[0014] Furthermore, a water pump is fixedly connected to the left side of the cavity, and the left end of the input end of the water pump extends into the interior of the water storage cavity.

[0015] Beneficial Effects: This fixture precisely positions the cylinder head via grooves, ensuring its stability during machining and laying the foundation for subsequent precision processing. It offers high flexibility in adjusting the milling head's position and angle. Controlling the air pump to push the support plate through the sliding groove adjusts the milling head's lateral position; the geared motor drives the cylinder and cross plate to rotate, adjusting the milling head's angle to meet different machining needs; the motor drives the rotating column and toothed drum to rotate, causing the carriage to slide on the cross plate's groove, achieving precise adjustment of the milling head's longitudinal position. Through the coordinated work of these components, the milling head can be precisely adjusted in multiple dimensions in terms of position and angle. During machining, waste material is discharged through the drain holes in the grooves, preventing waste accumulation from affecting machining quality. The extension rod ensures that the water spray nozzle and milling head remain in the same position during movement. Simultaneously, the water spray nozzle sprays coolant to cool and clean the milling head and machining area, ensuring machining accuracy and the milling head's lifespan, thus effectively guaranteeing the milling quality of the cylinder head.

[0016] The tooling design is ingenious in handling waste and coolant. After the waste and coolant are mixed, they first fall into the cavity through the leakage holes in the groove, then enter the screening tank via an inclined plate. The fine sieve in the screening tank achieves initial separation, and the coolant flows out through the leakage holes. The remaining mixture enters the receiving chamber through the outlet, where the coarse sieve on the inner wall of the receiving chamber performs a second screening, intercepting larger waste particles, and allowing the coolant to flow out further. This multi-screening method achieves efficient separation of waste and coolant. The separated coolant is pumped back into the storage chamber, achieving coolant recycling and reuse, ensuring a continuous coolant supply during processing, reducing coolant waste, and lowering processing costs. Simultaneously, the waste is effectively collected in the receiving chamber, facilitating centralized cleaning, maintaining the normal working environment of the tooling, improving the overall efficiency and cleanliness of the processing system, and making the entire processing process more environmentally friendly and efficient.

[0025] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example

[0027] like Figures 1-7As shown, a tooling for horizontal milling of cylinder heads is provided, including a cavity 1. A groove 2 is formed on the upper surface of the cavity 1, and multiple material leakage holes 3 are formed on the upper surface of the groove 2. A sliding groove 4 is formed on the right side of the upper surface of the cavity 1. A support plate 5 is slidably connected inside the sliding groove 4. A geared motor 6 is fixedly connected to the upper surface of the support plate 5. A cylinder 7 is fixedly connected to the top of the output end of the geared motor 6. The top of the cylinder 7 extends through to the top of the sliding groove 4 and is fixedly connected to a horizontal plate 8. Sliding grooves 9 are symmetrically formed on the outer side wall of the horizontal plate 8. A slide 10 is slidably connected to the outer side wall of the two sliding grooves 9. A slot 11 is fixedly connected to the lower surface of the slide 10. A milling head 12 is engaged inside the slot 11. A rotating column 13 is rotatably connected to the inner side wall of the slide 10. A toothed rotating cylinder is fixedly connected to the outer side wall of the rotating column 13. 14. A moving groove 16 is provided on the lower surface of the horizontal plate 8. A conveying tooth 17 is provided on the lower surface of the moving groove 16. The toothed rotating cylinder 14 is meshed with the conveying tooth 17. A motor 18 is fixedly connected to the front surface of the slide 10. The output end of the motor 18 passes through the interior of the slide 10 and is fixedly connected to the front end of the rotating column 13. A load-bearing plate 27 is fixedly connected to the right side of the cavity 1. A control air pump 28 is fixedly connected to the upper surface of the load-bearing plate 27. The output ends of the control air pump 28 are all fixedly connected to the sliding groove 4. The extension rod 21 includes a long cavity 101. An extension crossbar 102 is slidably connected inside the long cavity 101. A water outlet 103 is provided inside the extension crossbar 102. A water pipe 104 is fixedly connected between the long cavity 101 and the water pumping rod 26. A water pumping nozzle 105 is fixedly connected to the lower surface of the extension crossbar 102.

[0028] First, the cylinder head to be processed is placed in the groove 2 on the upper surface of the cavity 1. The groove 2 is designed to accurately position the cylinder head and ensure its stability during processing. At this time, check whether the cylinder head is placed accurately to ensure the smooth progress of subsequent processing. Start the control air pump 28 on the load-bearing plate 27. The gas output by the control air pump 28 enters the sliding groove 4, pushing the support plate 5 to slide within the sliding groove 4. Since the support plate 5 is fixedly connected to components such as the reduction motor 6, cylinder 7, horizontal plate 8, slide 10, and milling head 12, the lateral position of the milling head 12 can be adjusted to a suitable starting position for machining. The reduction motor 6 is turned on, and its output drives the cylinder 7 to rotate. The horizontal plate 8 at the top of the cylinder 7 rotates accordingly, which in turn drives the slide 10 and milling head 12 mounted on the horizontal plate 8 to rotate, thereby adjusting the angle of the milling head 12 to meet different machining requirements. The motor 18 on the front surface of the slide 10 is started, and its output drives the rotating column 13 to rotate. The toothed rotating cylinder 14 on the outer wall of the rotating column 13 rotates accordingly. Because the toothed rotating cylinder 14 meshes with the transmission teeth 17 in the moving groove 16 on the lower surface of the horizontal plate 8, the slide 10 slides on the sliding groove 9 of the horizontal plate 8, achieving precise adjustment of the longitudinal position of the milling head 12. Once the position and angle of the milling head 12 are adjusted, the milling head 12 is started to mill the cylinder head placed in the groove 2. During the processing, the waste generated will fall through multiple material leakage holes 3 on the upper surface of the groove 2 to avoid the accumulation of waste affecting the processing quality. During the processing, the water pump rod 26 draws out the coolant, which enters the long cavity 101 of the extension rod 21 through the water pipe 104, and then sprays out from the water pump nozzle 105 through the water outlet hole 103 in the extension crossbar 102 to cool and clean the milling head 12 and the processing part, ensuring the processing accuracy and the service life of the milling head 12.

[0029] In this embodiment, a perforated plate 19 is symmetrically fixedly connected to the left side of the carriage 10. A vertical column 20 is rotatably connected inside the perforated plate 19. An extension rod 21 is fixedly connected to the outer wall of the vertical column 20. A water storage chamber 22 is fixedly connected to the left side of the cavity 1. An arc groove 23 is formed on the upper surface of the water storage chamber 22. An extension cavity 24 is formed on the left side of the upper surface of the water storage chamber 22. A sliding rod 25 is slidably connected inside the extension cavity 24. The upper surface of the sliding rod 25 is fixedly connected to the lower surface of the extension rod 21. A water-drawing rod 26 is fixedly connected to the right side. The bottom end of the water-drawing rod 26 extends into the interior of the water storage chamber 22. The outer side wall of the water-drawing rod 26 contacts the inner side wall of the arc groove 23. Inclined plates 29 are symmetrically opened inside the cavity 1. A screening tank 30 is fixedly connected between the inclined plates 29. A leakage hole 31 is symmetrically fixedly connected to the outer side wall of the screening tank 30. A fine sieve hole 32 is symmetrically opened on the inner side wall of the screening tank 30. A water pump 36 is fixedly connected to the left side inside the cavity 1. The left end of the input end of the water pump 36 penetrates into the interior of the water storage chamber 22.

[0030] The cylinder head is placed and fixed in the groove of cavity 1. At this time, the slide 10 is in the initial position, and the vertical column 20, extension rod 21 and other components on the perforated plate 19 on its left side are also in the corresponding initial positions. The water storage chamber 22 on the left side of cavity 1 has been filled with coolant. The bottom end of the water-drawing rod 26 on the lower surface of the extension rod 21 extends into the water storage chamber 22, and the outer wall contacts the arc groove 23. When the slide 10 moves, it drives the perforated plate 19, vertical column 20 and extension rod 21 to move. The extension rod 21 slides in the extension cavity 24 through the sliding rod 25, so that the position of the water-drawing rod 26 changes in the water storage chamber 22, while maintaining contact with the arc groove 23. When the milling head 12 is machining the cylinder head, the water-drawing rod 26 draws the coolant in the water storage chamber 22 and delivers it to the machining area through the extension rod 21 and other components to cool and lubricate the milling head and the machining surface. The waste material generated during machining mixes with the coolant and falls into the cavity 1 through the leakage hole 3 on the groove 2. The mixture flows through the inclined plate 29 and then enters the screening tank 30. The screening tank 30 separates waste and coolant through the fine sieve holes 32. The coolant flows out through the drain hole 31. The water pump 36 on the left side of the cavity 1 is started to pump the coolant separated by the screening tank 30 back into the water storage chamber 22, realizing the recycling and reuse of coolant, ensuring the continuous supply of coolant during the processing, and effectively treating waste and maintaining the normal working environment of the tooling.

[0031] In this embodiment, the front surface of the cavity 1 is provided with an outlet 33, the inside of the outlet 33 is connected to a material taking chamber 34, and the inner sidewall of the material taking chamber 34 is provided with a coarse sieve hole 35.

[0032] During cylinder head milling, the mixture of waste material and coolant undergoes initial separation in the screening tank 30 inside the cavity 1. The remaining mixture continues to flow within the cavity 1. At this point, the outlet 33 on the front surface of the cavity 1 comes into play. It connects to the material collection chamber 34, allowing the mixture to enter the material collection chamber 34 from the outlet 33. The coarse screen holes 35 on the inner wall of the material collection chamber 34 further screen the incoming mixture. Larger waste particles are intercepted by the coarse screen holes 35 within the material collection chamber 34, while the coolant that has passed through the coarse screen flows out through the holes 35, further separating the waste material and coolant. When a certain amount of waste material accumulates in the material collection chamber 34, it can be easily removed from the outlet 33 by withdrawing the material collection chamber 34 for centralized processing. This design ensures effective waste collection and easy cleaning, while also allowing for better separation of the coolant, which is then pumped back to the water storage chamber 22 by the water pump 36 for recycling, improving the overall efficiency and cleanliness of the machining system.

[0033] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
