Description

Technical Field

[0001] This utility model relates to the field of valve processing technology, and specifically to a cutting device for valve processing. Background Technology

[0002] Valves are devices used in fluid systems to control the direction, pressure, and flow rate of fluids. They enable the flow or stop of media (liquids, gases, powders) within piping and equipment and control their flow rate. In valve manufacturing, sealing grooves need to be machined into valve fittings so that a sealing ring can be placed inside, achieving a sealing effect after the fitting is installed in the valve. Currently, sealing grooves on fittings are usually machined individually. Since fittings typically require multiple sealing grooves, this results in relatively slow manufacturing efficiency. Therefore, there is an urgent need to design a cutting device for valve manufacturing to solve the above problems. Utility Model Content

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] like Figure 1-3As shown in the figure, a cutting device for valve processing provided by this utility model includes a worktable 1, a mounting shell 2 fixed on the top of the worktable 1, a rotating mechanism inside the mounting shell 2, a chuck 3 fixed to the outside of the rotating mechanism extending to the outside of the mounting shell 2, a workpiece body 4 fixed inside the chuck 3, a vertical rail 7 on one side of the mounting shell 2, a sliding groove 8 inside the vertical rail 7, a slider 9 slidably connected inside the sliding groove 8, a tool holder 10 fixed to one side of the outer wall of the slider 9, uniformly distributed grooving cutters 11 fixed to the bottom of the tool holder 10, and a feed mechanism for the movement of the tool holder 10 on the top of the vertical rail 7.

[0020] Specifically, in this embodiment, a workbench 1 is included, and a mounting shell 2 is fixed to the top of the workbench 1. A rotating mechanism is provided inside the mounting shell 2, and a chuck 3 is fixed to the outside of the mounting shell 2 through the output end of the rotating mechanism. The chuck 3 is rotated by the rotating mechanism. A workpiece body 4 is fixed inside the chuck 3. The workpiece body 4 is a valve accessory that needs to be machined with a sealing groove. A vertical rail 7 is provided on one side of the mounting shell 2. A sliding groove 8 is opened inside the vertical rail 7. A slider 9 is slidably connected inside the sliding groove 8. A tool holder 10 is fixed to the outer wall of one side of the slider 9. A grooving knife 11 is evenly distributed at the bottom of the tool holder 10. The number of grooving knives 11 is equal to the number of grooves that need to be cut on the workpiece body 4, usually three. A feeding mechanism for the movement of the tool holder 10 is provided at the top of the vertical rail 7. The feeding mechanism is used to drive the tool holder 10 to perform a feeding movement, and the feeding direction of the grooving knife 11 is in a straight line with the center of the workpiece body 4.

[0021] The present invention provides a cutting device for valve processing, which drives the chuck 3 that fixes the workpiece to rotate through a rotating mechanism, and drives the tool holder 10 with multiple grooving tools 11 to move through a feeding mechanism, so that the workpiece body 4 is more efficient in grooving, thereby improving the production efficiency of valve accessories.

[0022] In another embodiment of this utility model, the rotating mechanism includes a gear 12 connected to the inside of the mounting housing 2 by a bearing. A gear 14 is connected to the bearing inside the mounting housing 2, and the gear 14 meshes with the gear 12, enabling the gear 12 to drive the gear 14 to rotate at high speed. A motor 16 is fixed to one outer wall of the mounting housing 2, and the output shaft of the motor 16 is connected to the gear 12 via a key, allowing the motor 16 to drive the gear 12 to rotate. A gear 3 15 is connected to the bearing inside the mounting housing 2, and a gear 2 13 is fixed to one end of the gear 14. The gear 2 13 and gear 3 15... The meshing of gear 13 and gear 2 (diameter larger than gear 3, 15) allows gear 3, 15 to achieve a higher rotational speed. The output shaft of gear 3, 15 is fixed to chuck 3, enabling chuck 3 to rotate at speeds several times higher than the output speed of motor 16. Gear 1, 12 drives gear 14 and gear 2, 13, which in turn drives chuck 3 at high speed via gear 3, 15. This high-speed rotation of the workpiece body 4 results in higher surface quality during chip cutting, leading to a better surface finish and higher surface precision during grooving, thus improving the machining quality of valve fittings. A mounting bracket 5 is fixed to one outer wall of the mounting housing 2, and a vertical rail 7 is fixed to the bottom of the mounting bracket 5. The feeding mechanism includes a servo electric cylinder 6 fixed to the top of the mounting bracket 5. The output end of the servo electric cylinder 6 is fixed to the slider 9. The specific cutting parameters are as follows: the rotational speed of the workpiece body 4 is preferably 1500-2500 rpm, and the feed rate of the grooving cutter 11 is preferably 0.1-0.3 mm / rpm. The workpiece body 4 is made of brass, so the grooving cutter 11 adopts a 35° cutting edge to reduce the sticking phenomenon. Furthermore, both the servo electric cylinder 6 and the motor 16 are controlled by a control system based on existing technology. This allows the servo electric cylinder 6 to achieve a staged feed effect, thereby preventing chips from getting tangled in the tool and reducing the load on the tool. The top outer wall of the mounting shell 2 is integrally formed with an oil inlet 17, and the top of the oil inlet 17 is threadedly connected to a sealing cap 18. Lubricating oil is added to the inside of the mounting shell 2 through the oil inlet 17, which reduces the wear when gear 12, gear 14, gear 2 13 and gear 3 15 mesh with each other. Moreover, the chip cutting device of this utility model has a simplified structure compared with the existing CNC lathe. It is a special equipment for grooving parts, so the device has a lower cost and saves production costs.

[0023] Working principle: In use, the workpiece body 4 is correctly clamped by the chuck 3, and then the motor 16 drives the gear 12 to rotate. When the gear 12 rotates, it drives the gear column 14 to rotate at high speed, which in turn drives the gear 13 to rotate. When the gear 13 rotates, it drives the gear 15 and the chuck 3 to rotate at an even higher speed. Then, the servo cylinder 6 drives the slider 9 to move downward, which in turn drives the tool holder 10 and the grooving tool 11 to perform grooving on the workpiece.

[0024] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
