Description

Technical Field

[0001] This utility model relates to the field of lathes, and in particular to a chip removal structure for machining seals. Background Technology

[0002] As critical functional components in industrial equipment, the machining accuracy and surface integrity of seals directly affect subsequent sealing performance and service life. During lathe machining of seals, high-speed cutting is typically used for precision machining of their end faces, inner holes, or outer diameters, with particularly high requirements for the surface quality of sealing or mating surfaces. However, in traditional machining processes, metal chips generated during cutting tend to accumulate, bounce, or splash within the machining area. Some chips even directly adhere to or impact the machined surface, easily causing minor scratches or indentations, thus affecting the sealing accuracy of the seal and the subsequent assembly effect.

[0003] However, in traditional structures, the spray position and direction of coolant are mostly fixed, usually set at an angle above the tool or workpiece; this chip removal path is unstable, the flow field is not concentrated, and it is difficult to effectively guide the chips away from the cutting zone quickly; this not only reduces chip removal efficiency, but also exacerbates the risk of secondary interference of chips on the workpiece surface. Especially in the context of miniaturization, thinning of sealing components and increasingly higher requirements for surface finish, this type of chip removal method is becoming increasingly unsuitable for precision machining scenarios. Utility Model Content

[0004] This utility model provides a chip removal structure for processing sealing components, which is used to solve related technical problems in the background art.

[0005] The technical solution provided by this utility model is as follows: A chip removal structure for sealing component processing includes: a base, a protective sheet metal disposed on the base, a lathe tool holder disposed on the outside of the protective sheet metal, and a workpiece inside the protective sheet metal; the lathe tool in the lathe tool holder passes through the protective sheet metal to process the workpiece;

[0006] The tool holder has a liquid storage chamber inside, and two water outlets are opened on the side wall of the tool holder, which are connected to the liquid storage chamber. The two water outlets are located above and below the tool, respectively, and the cutting fluid from the water outlets is sprayed out in the feed direction of the tool tip.

[0007] In one embodiment, the liquid storage chamber is connected to the lathe cutting fluid supply system.

[0008] In one embodiment, a first nozzle is provided on the inner side of the protective sheet metal, the first nozzle is above the workpiece, and the cutting fluid of the first nozzle is sprayed onto the workpiece from top to bottom.

[0009] In one embodiment, the first nozzle is connected to the lathe cutting fluid supply system.

[0010] In one embodiment, a hob cutter holder is provided on the other side of the protective sheet metal, and the hob cutter in the hob cutter holder passes through the protective sheet metal for processing.

[0011] In one embodiment, a second nozzle is provided on the inner side of the protective sheet metal, and the second nozzle sprays cutting fluid onto the hob from above.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) The chip removal structure for sealing component processing of this utility model adopts a method of setting a liquid storage cavity in the tool holder and setting two water outlets above and below the tool. High pressure cutting fluid is sprayed out from both directions at the top and bottom along the feed direction of the tool tip, forming a liquid flow that is close to the horizontal of the tool. This achieves the purpose of quickly flushing the generated iron chips away from the tool tip and the workpiece surface during the cutting process, thereby preventing iron chips from being stuck on the workpiece surface during the processing and effectively avoiding scratches caused by contact. This solves the technical problem of workpiece surface scratches and affecting processing quality caused by poor chip removal, iron chip splashing and rebound in traditional lathe structures.

[0014] (2) The chip removal structure for sealing component processing of this utility model adopts the method of setting a first nozzle above the workpiece on the inner side of the protective sheet metal. High-pressure cutting fluid is sprayed from top to bottom to the non-machined area of ​​the workpiece, which not only enhances the cooling effect on the workpiece, but also pushes the chips attached to the non-machined surface of the workpiece to fall down. It forms a coordinated chip removal path with the cutting fluid sprayed from the tool holder outlet, achieving the purpose of efficient cooling and smooth chip removal at the same time. This achieves the technical effect of avoiding chip accumulation, reducing the risk of scratches, and ensuring processing quality. In turn, it solves the technical problems of low cooling efficiency and poor chip removal that easily damage the workpiece surface in traditional structures. Attached Figure Description

[0019] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0020] Example 1

[0021] like Figure 1-3 As shown, this utility model is a chip removal structure for sealing component processing, including: a base 1, a protective sheet metal 2, a lathe tool holder 3, and a workpiece. The protective sheet metal 2 is installed on the base 1 to isolate the cutting area from the operator area, improving safety; the lathe tool holder 3 is located on one side of the protective sheet metal 2, and the lathe tool 4 extends into the protective sheet metal 2 to perform cutting processing on the workpiece.

[0022] A liquid storage chamber 5 is provided inside the tool holder 3 to contain high-pressure cutting fluid. This liquid storage chamber 5 is connected to the cutting fluid supply system of the lathe to ensure a continuous supply of high-pressure fluid. Two water outlets 6 are provided on the side wall of the tool holder 3. The two water outlets 6 are located above and below the cutting tool 4, respectively, and both are connected to the liquid storage chamber 5.

[0023] Two outlets 6 spray high-pressure coolant from above and below the cutting tool 4 towards the feed direction of the tool tip, forming a synergistic cooling impact path. The high-pressure coolant can significantly reduce the cutting heat at the tool tip, while providing a stable liquid flow field, effectively carrying away the iron chips generated during the cutting process from the machining area.

[0024] When the cutting tool 4 cuts the workpiece, the cutting fluid is simultaneously sprayed from two outlets 6 at high pressure through the reservoir 5 inside the tool holder 3, acting on the upper and lower sides of the cutting tool 4 respectively. The spray direction is consistent with the feed direction of the tool tip. Through this fluid flow guidance method that is almost horizontal with the cutting tool 4, iron chips are guided by the cutting fluid to be discharged from the other side of the workpiece in the early stage of formation, avoiding their retention, rebound, or splashing onto the workpiece surface. This significantly reduces the risk of surface scratches and improves the surface finish and stability.

[0025] Example 2

[0026] This embodiment 2 further optimizes the first embodiment by providing a first nozzle 7 on the inner side of the protective sheet metal 2. The first nozzle 7 is located above the workpiece and is connected to the high-pressure cutting fluid supply system via a pipe. The nozzle sprays cutting fluid downwards, acting on the other side of the workpiece machining area and inside the protective sheet metal 2.

[0027] During the processing, the first nozzle 7 continuously sprays high-pressure cutting fluid from above onto the workpiece and protective sheet metal 2, which not only enhances the cooling effect on the processing area, but also pushes the chips downwards, forming a coordinated chip removal path with the cutting fluid sprayed from the outlet 6.

[0028] In this embodiment, the setting of the first nozzle 7 effectively improves the cooling efficiency of the workpiece and further optimizes the chip guiding direction, making the chip removal path smoother and effectively avoiding the impact of iron chips on the surface accuracy of the workpiece.

[0029] Example 3

[0030] Based on embodiment 1 or 2, a hob holder 8 is symmetrically arranged on the other side of the protective sheet metal 2. A hob 9 is arranged inside the hob holder 8. The hob 9 passes through the protective sheet metal 2 and extends into the interior to process the workpiece.

[0031] A second nozzle 10 is provided on the inner side of the protective sheet metal 2 corresponding to the position of the hob cutter 9. The second nozzle 10 is located above the hob cutter 9 and is used to spray high-pressure coolant from above onto the hob cutter 9.

[0032] When the hob 9 performs a cutting task, the cutting fluid sprayed from the second nozzle 10 is sprayed towards the head of the hob 9, directly acting on the tooth area of ​​the hob 9 to achieve continuous and efficient cooling and chip removal.

[0033] This embodiment expands the device's adaptability to various types of cutting tools. While ensuring the machining accuracy of the hob 9, it significantly improves chip removal efficiency, avoids the risk of iron chips accumulating in the backlash of the hob 9, and improves machining cycle time and tool life.
