Description

Technical Field

[0001] The utility model relates to the technical field of sealing component processing, in particular to a milling machine for processing mechanical sealing components. Background Art

[0002] Milling machines mainly refer to machine tools that use milling cutters to process various surfaces of workpieces. Its working principle is mainly to drive the tool to rotate and cut through the spindle, and use the tool to rotate and cut on the surface of the workpiece, so that the surface of the workpiece can be processed with shape, size and position accuracy. Milling machines can process various complex shapes such as planes, grooves, toothed parts, spiral surfaces and various curved surfaces. Milling machines are widely used in machinery manufacturing, mold processing, aerospace, automobile manufacturing and other fields. Among them, milling machines are needed to cut workpieces when processing mechanical seals.

[0003] For example, the Chinese patent "A Milling Machine for Processing Mechanical Seals" with announcement number CN213319037U includes a base and a box body, wherein either end of the top of the base is fixedly connected to the box body, the end of the top of the base away from the box body is fixedly connected to a fixed block, and a slide groove is provided on the side of the middle of the box body close to the fixed block; a cylinder is fixedly connected to the center position of the top of the fixed block, and a lifting platform is fixedly connected to the driving end of the cylinder, and the end of the lifting platform close to the box body is slidably connected to the slide groove, a slide seat is slidably connected to the top of the lifting platform, and a workbench is slidably connected to the top of the slide seat; a machine head is fixedly connected to the top of the same side wall of the box body and the slide groove, and a spindle is rotatably connected to the center position of the bottom of the machine head.

[0004] Although the above-mentioned prior art can realize the processing of seals, in actual use, on the one hand, the position adjustment of the milling cutter is not flexible enough. When the processing position of the workpiece needs to be changed, the workpiece is first removed from the clamping mechanism and the position of the workpiece is adjusted before being re-fixed on the clamping mechanism. As a result, multiple disassembly and assembly may easily cause errors in the position of the workpiece, thereby reducing the processing accuracy of the workpiece. On the other hand, a large amount of debris is easily generated during the processing of the workpiece. The large amount of debris generated during the processing of the workpiece is cleaned by blowing, which makes it difficult to clean the debris attached to the workpiece, thereby reducing the debris cleaning effect. Therefore, it does not meet the existing needs. In this regard, we propose a milling machine for processing mechanical seals. Utility Model Content

[0005] The utility model aims to provide a milling machine for machining mechanical seals, so as to solve the problems that the position adjustment of the milling cutter proposed in the above background technology is not flexible enough and a large amount of debris is easily generated during the machining of the workpiece.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model can adjust the position of the milling cutter head through the mounting frame and the moving seat. When the processing position needs to be changed, the fourth motor is first turned on to make the output shaft of the fourth motor drive the second pulley to move in the limit groove. At this time, the mounting frame is moved together with the milling cutter head in the X-axis direction through the second pulley until the milling cutter head moves to a suitable position, and then the third hydraulic telescopic device is turned on to make the telescopic ends of the third hydraulic telescopic devices at both ends maintain synchronous and opposite motion states, and the moving seat is moved together with the milling cutter head in the Y-axis direction through the telescopic ends of the third hydraulic telescopic device until the milling cutter head moves to a suitable position, and finally the seal is processed by the milling cutter, so that the movement of the milling cutter head is more flexible.

[0017] 2. The utility model can clean the debris generated during the processing of the seal through the electric push rod and the circular brush. After the seal is processed for a period of time, the second motor is turned on to flip the seal. During the flipping process, some debris is detached from the seal by its own gravity until the seal is flipped 180°. At this time, the electric push rod and the third motor are turned on to extend the telescopic end of the electric push rod. The extension of the telescopic end of the electric push rod drives the rotating circular brush to move upward until the circular brush contacts the lower end of the seal and cleans the debris attached to the seal. At the same time, the upper end of the seal is processed by the milling cutter. After a period of time, the seal is flipped again. While cleaning the debris, the processing of the seal is not stopped, thereby speeding up the processing rate of the seal.

[0018] 3. The utility model uses the second motor and the C-shaped clamping strip to avoid human intervention in flipping the seal. After completing the processing of one side of the seal, the second motor is turned on, so that the output shaft of the second motor drives the C-shaped clamping strip to rotate until the C-shaped clamping strip rotates 180°. At this time, the seal rotates together with the C-shaped clamping strip until the other side of the seal is under the milling cutter head. The seal is then processed by the milling cutter, which reduces the intervention of operators during processing, thereby improving the processing efficiency of the seal.
