Description

Technical Field

[0001] The utility model belongs to the technical field of power heads, in particular to a power head for turning special-shaped valve bodies. Background Art

[0002] In the field of machining, especially in the turning of special-shaped valve bodies, the power head is a key piece of equipment, and its performance directly impacts machining efficiency and quality. The cutting fluid system, a crucial component of the power head, plays a crucial role in reducing cutting temperatures, minimizing tool wear, and improving machining accuracy. However, existing cutting fluid systems in power heads present several practical challenges.

[0003] Existing cutting fluid systems for power heads are primarily divided into two types. The first type utilizes numerous cutting fluid pipelines to achieve a relatively comprehensive and efficient cutting fluid supply. The advantage of this approach is that the cutting fluid fully covers the machining area, effectively reducing cutting temperatures and protecting both the tool and the workpiece. However, its disadvantages are also obvious: the routing of cutting fluid pipelines is complex, requiring high maintenance and construction costs, and pipeline blockages or leaks can easily affect machining efficiency.

[0004] Another approach involves deploying a small number of cutting fluid lines to meet the cutting fluid supply needs within a limited area. This approach offers advantages in terms of simplicity, ease of maintenance, and low cost. However, its disadvantage is that the cutting fluid coverage area is limited, making it difficult to fully meet the cooling and lubrication requirements of complex workpieces such as special-shaped valve bodies, thus impacting machining quality and tool life.

[0005] Furthermore, when turning special-shaped valve bodies, the complex shape of the workpiece causes the contact area between the tool and the workpiece to constantly change during the cutting process, necessitating adjustments to the required amount and supply of cutting fluid. However, existing cutting fluid systems often lack the flexibility to adapt to machining requirements, leading to insufficient or wasted cutting fluid supply, further impacting machining efficiency and costs.

[0024] As attached Figure 1 To the attached Figure 4 As shown:

[0025] The utility model provides a power head for turning a special-shaped valve body, comprising a power head drive box 1, a drive component 2, a drive head 3, a power seat 4, a rotary cutting fluid system 5 and a cutting fluid nozzle pipe 6. The input end of the power head drive box 1 is fixed to the output end of the drive component 2 fixedly mounted on its outside. The output end of the power head drive box 1 is the drive head 3, and the drive head 3 is mounted together with the power seat 4. The rotary cutting fluid system 5 is respectively rotatably connected to the drive head 3 and fixedly connected to the power head drive box 1, wherein the cutting fluid nozzle pipe 6 is mounted on the outside of the rotary cutting fluid system 5.

[0026] Furthermore, the rotary cutting fluid system 5 includes a hood 51, a center tube 52, a moving tube 53, a serpentine drag chain 54, and a rotating cover 55. The hood 51 is fixedly connected to the power head drive box 1. The inner coil end of the serpentine drag chain 54 is fixed to the outer surface of the center tube 52, while the outer coil end is fixed to the inner surface of the rotating cover 55, which is rotatably mounted within the hood 51. The rotating cover 55 is not only rotatably connected to the center tube 52 and the hood 51, but is also fixedly connected to the moving tube 53, forming a stable rotating structure. This design allows the cutting fluid pipeline 50 to move freely as the rotating cover 55 rotates, ensuring that the cutting fluid can be continuously and stably supplied to the processing area.

[0027] Furthermore, the outer surface of the moving cylinder 53 is provided with a worm gear 56, which meshes with a worm 57 rotatably mounted within the upper portion of the hood 51. Either end of the worm 57 is secured to the output terminal of a drive motor 58 fixedly mounted externally above the hood 51. When the drive motor 58 is activated, the worm 57 rotates the worm gear 56, which in turn rotates the moving cylinder 53 and the rotating cover 55. This worm gear mechanism design not only offers a simple structure and stable transmission, but also enables precise rotational control, satisfying the precise adjustment requirements during machining.

[0028] Furthermore, a cutting fluid conduit 50 is installed within the serpentine drag chain 54. Its two ends are connected to a cutting fluid nozzle 59 and a cutting fluid nozzle 6, respectively, mounted on the exterior of the hood 51. Cutting fluid enters the conduit through the nozzle 59, is guided through the cutting fluid conduit 50 inside the serpentine drag chain 54, and is ultimately ejected from the cutting fluid nozzle 6, cooling and lubricating the machining area. This design ensures a continuous and stable supply of cutting fluid to the machining area while preventing accumulation and clogging of the conduit.

[0029] Furthermore, the cutting fluid nozzle pipe 6 is mounted on the surface of the rotating cover 55 and positioned around the power base 4. As the rotating cover 55 rotates, the cutting fluid nozzle pipe 6 can move in a circular trajectory around the power base 4. This design not only expands the coverage area of ​​the cutting fluid but also improves the utilization rate of the cutting fluid, ensuring effective cooling and lubrication during the machining process.

[0030] Furthermore, the inner end of the serpentine drag chain 54 wraps around the outer surface of the central tube 52 in no more than one turn, while the outer end rests on the inner surface of the moving tube 53 in an arc. This design ensures that the serpentine drag chain 54 does not interfere with either the central tube 52 or the moving tube 53 during movement, while providing ample space for movement. Furthermore, the same surface of the serpentine drag chain 54 contacts both the central tube 52 and the moving tube 53. This contact pattern not only reduces friction and wear but also improves the stability and durability of the entire cutting fluid system.

[0031] Furthermore, the central cylinder 52 is located inside the moving cylinder 53, and the spacing between the two allows the serpentine drag chain 54 to move in a spiral trajectory. This design not only ensures that the serpentine drag chain 54 can move freely with the rotation of the rotating cover 55, but also provides it with sufficient movement space and flexibility. This spacing also prevents excessive bending and squeezing of the cutting fluid pipeline 50 during movement, ensuring a smooth supply of cutting fluid.

[0032] The working principle is as follows: First, the input end of the power head drive box 1 is fixed to the output end of the external fixed drive component 2. The drive component 2 (such as a motor, etc.) provides power to drive the transmission mechanism inside the power head drive box 1. The output end of the power head drive box 1 is the drive head 3.

[0033] A rotating cutting fluid system 5 is incorporated into the power head 3 to provide a continuous supply of cutting fluid. This system comprises a hood 51, a central cylinder 52, a moving cylinder 53, a serpentine drag chain 54, and a rotating cover 55. The hood 51 is fixedly connected to the power head drive box 1, providing protection for the entire cutting fluid system. The central cylinder 52 is fixedly mounted within the hood 51 and rotatably connected to the drive head 3, ensuring that the cutting fluid system can adjust its position as the drive head rotates.

[0034] The inner coiled end of the serpentine drag chain 54 is fixed to the outer surface of the central cylinder 52, while the outer coiled end is fixed to the inner surface of a rotating cover 55 rotatably mounted within the hood 51. The rotating cover 55 is not only rotationally connected to the central cylinder 52 and the hood 51, but is also fixedly connected to the moving cylinder 53, forming a stable rotating structure. Thus, when the drive motor 58 is activated, the worm 57 rotates the worm gear 56, which in turn drives the moving cylinder 53 and the rotating cover 55 to rotate together. Because the ends of the serpentine drag chain 54 are fixedly connected to the central cylinder 52 and the rotating cover 55, respectively, the serpentine drag chain 54 moves freely as the rotating cover 55 rotates.

[0035] Meanwhile, a cutting fluid conduit 50 is provided inside the serpentine drag chain 54. The two ends of the conduit are connected to a cutting fluid nozzle 59 and a cutting fluid nozzle 6, respectively, mounted on the outside of the hood 51. Cutting fluid enters the conduit through the cutting fluid nozzle 59, is guided through the cutting fluid conduit 50 inside the serpentine drag chain 54, and is finally ejected from the cutting fluid nozzle 6, thereby cooling and lubricating the machining area.

[0036] In addition, the cutting fluid nozzle pipe 6 is mounted on the surface of the rotating cover 55 and is located around the power base 4. As the rotating cover 55 rotates, the cutting fluid nozzle pipe 6 can move in a circular trajectory around the power base 4, thereby expanding the coverage area of ​​the cutting fluid, improving the utilization rate of the cutting fluid, and ensuring the cooling and lubrication effect during the processing.

[0037] Throughout operation, the inner end of the serpentine drag chain 54 wraps around the outer surface of the central tube 52 in no more than one turn, while the outer end arcs against the inner surface of the moving tube 53. This design ensures that the serpentine drag chain 54 does not interfere with either the central tube 52 or the moving tube 53 during movement, while providing ample space for movement. Furthermore, the same surface of the serpentine drag chain 54 contacts both the central tube 52 and the moving tube 53. This contact pattern not only reduces friction and wear but also improves the stability and durability of the entire cutting fluid system.

[0038] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the scope of protection of the utility model.
