Description

Technical Field

[0001] The utility model relates to the technical field of shaft processing, in particular to a rough turning outer circle mechanism for shaft processing. Background Art

[0002] At present, the processing of external cylindrical surfaces can be divided into turning, grinding, rolling, etc., and can be divided into rough processing, fine processing, super fine processing, etc. according to the surface processing accuracy. In the domestic diesel machinery pump plunger pair processing industry, the external cylindrical processing of plungers generally adopts the following process flow: blank → rough grinding of external cylindrical → fine grinding of external cylindrical → polishing of external cylindrical → fine polishing of external cylindrical (matching grinding pairs). There are many external cylindrical grinding steps and the process route is long; the external cylindrical straight groove of the plunger working surface is generally milled with a milling cutter on a universal lifting milling machine before the parts are heat treated (the hardness of the parts is low).

[0003] To improve shaft machining, when rough turning the outer surface of a plunger mechanism, the milling cutter has a consistent grinding force and a single processing function. Different grinding angles and forces require the replacement of the milling cutter, making it difficult to meet the grinding process requirements. Among the disclosed technologies, the utility model patent CN215468335U discloses a rough turning mechanism for shaft blanks. The lathe is equipped with a shaft machining mechanism, which includes a connecting post, a circular base, a mounting shaft, a milling cutter, and a storage chamber. The connecting post is provided on the lathe, and the circular base is connected to the connecting post. Although the shaft machining functionality is increased to meet the processing requirements of different devices, the device still has shortcomings during use. For example, multiple milling cutters require multiple drive devices to provide the required kinetic energy for their rotation, and a single drive device cannot provide the required kinetic energy for the rotation of different milling cutters as needed, which leads to a high cost of the device. In addition, after the positions of the different milling cutters are adjusted, there is no position limit function for them, which easily causes displacement during subsequent milling operations, failing to meet the requirements of stable and safe machining, and the practical performance needs to be improved. Utility Model Content

[0004] The purpose of the present utility model is to provide a rough turning outer circle mechanism for shaft processing, so as to solve the problem proposed in the above background technology that multiple milling cutters need to be equipped with multiple driving devices to provide the required kinetic energy for their rotation, and it is impossible to use a single driving device to provide the required kinetic energy for rotation for different milling cutters as required, which leads to a high cost of the device. In addition, after the positions of different milling cutters are adjusted, there is a lack of position limiting function, and the subsequent milling cutters are prone to displacement during operation, which cannot meet the requirements of stable and safe processing, and the practical performance needs to be improved.

[0005] The top end of the push-pull rod is fixedly provided with a cylinder, and the top end of the push-pull rod is fixedly provided with a cylinder, and the cylinder is fixed with a top end connected to the contact surface of the lathe. The lower end of the cylinder is fixed with a cylinder, and the cylinder is fixed with a top end. The top end of the guide rail is fixedly provided with a toothed plate, and the bottom end of the guide rail is fixedly provided with a toothed plate, and the toothed plate is fixedly provided with a toothed plate.

[0006] Preferably, the top end of the outer wall of the protruding rod is a conical structure.

[0007] Preferably, an auxiliary component is provided above the outer wall of the column, and the auxiliary component includes a support plate, a connecting rod, an insertion rod, a compression spring and a button. The two support plates are respectively located on both sides of the outer wall of the column, a part of the support plate passes through the column, the top end of the support plate is fixedly connected to the connecting rod, the top end of the connecting rod is fixedly connected to the insertion rod, a compression spring is fixed between the two insertion rods, a part of the insertion rod passes through the column, and the outer end of the insertion rod is fixedly connected to the button.

[0008] Compared with the existing technology, the beneficial effects of the present invention are: the rough turning mechanism for the outer circle of the shaft has the following advantages over the traditional technology:

[0009] Through the cooperation between the lathe, base, workpiece, splint, milling cutter, enhancement component, joint, rotating rod, circular plate, push-pull rod and cylinder, the operator applies force to rotate the circular plate to adjust different milling cutters to be located directly above the workpiece, and then applies force downward to the strip plate so that it is sleeved on the outer wall of the adjacent protruding rod, which can limit the adjusted position of the milling cutter and enhance stability, so as to meet the subsequent stable and safe processing requirements, and then applies force to the knob to rotate the threaded barrel, and the third conical disk is pressed against the second conical disk and the outer wall of the first conical disk. At this time, the motor is started to rotate the vertical rod and the first conical disk. The transmission of the third conical disk can make the second conical disk, rotating rod and milling cutter pressed against it rotate together, and then the cylinder is controlled to make the milling cutter in the rotating state contact with the workpiece below it for grinding operation. A single motor can be used to provide the kinetic energy required for rotation for different milling cutters as needed, so as to reduce the cost of the device and enhance practical performance.

[0010] Through the cooperation between the column, the strip plate and the auxiliary components, the circular plate is rotated to adjust different milling cutters to be located directly above the workpiece. During the operation, after the strip plate slides upward on the outer wall of the column, the pressing force on the button can be released, and the compression spring is compressed and deformed, and the contact surface of the plate and the strip plate are pressed tightly, which can position the strip plate. When the circular plate is rotated to adjust different milling cutters to be located directly above the workpiece, there is no need to hold the strip plate with hands, which can provide certain convenience for the operator.
