Description

Technical Field

[0001] The invention relates to a whirlwind milling device with extrusion and polishing functions, belonging to the technical field of mechanical processing. Background Art

[0002] Whirlwind milling is one of the commonly used processing methods in the field of mechanical processing. The whirlwind milling device is an important component of the whirlwind milling. The existing whirlwind milling device includes a whirlwind milling head, which includes a tool holder body, a cutter disc and a tool. The cutter disc is installed in the middle of the tool holder body. The existing whirlwind milling only completes the milling of the workpiece. After milling the workpiece, the milled surface of the workpiece needs to be polished again. The processing of the entire workpiece actually includes two independent processes of milling and polishing. The workpiece is first milled on the whirlwind milling and then polished. The processing efficiency of the workpiece is low, and more manpower is consumed, and the economy of workpiece processing is poor. Summary of the Invention

[0003] The purpose of the present invention is to provide a whirlwind milling device with an extrusion polishing function, so as to solve the technical defect in the prior art that a workpiece needs to be polished after milling.

[0004] To solve the above problems, the technical solution adopted by the present invention is: a cyclone milling device with extrusion polishing function, including a machine base, which is used to be installed on a milling machine; a main shaft, the main shaft has through holes running through its two ends along its axial direction, the main shaft passes through the machine base and is rotatably installed on the machine base; a tool row, the tool row is installed at one end of the main shaft for milling the workpiece extending into the through hole; a drive motor, the drive motor is connected to the main shaft, and is used to drive the main shaft to rotate on the machine base; it also includes a follow-up tool calendering device, the follow-up tool calendering device is installed at the other end of the main shaft and rotates synchronously with the main shaft, the follow-up tool calendering device includes a pressing disc, the pressing disc is installed at the end of the main shaft and rotates synchronously with the main shaft; multiple pressing wheel brackets, multiple pressing wheel brackets are installed on the pressing disc and can move relative to the pressing disc toward or away from the center line of the through hole; a pressing wheel, the pressing wheel is rotatably installed on the pressing wheel bracket at one end close to the center line of the through hole, for contacting the workpiece surface and rotating relative to the workpiece surface to polish the workpiece surface. The calendering wheel in the present invention rests on the processed part of the workpiece. Since the overall main shaft of the calendering wheel rotates synchronously, it slides on the surface of the workpiece to grind the surface of the workpiece, so that the processed part of the surface of the workpiece is polished smooth. The present invention grinds the surface of the workpiece while milling the workpiece, and there is no need to grind the workpiece surface separately after milling is completed, which reduces the workpiece milling process, improves the workpiece milling efficiency, reduces the manpower investment in workpiece processing, and is economical.

[0005] As a further improvement of the present invention, a driven pulley is mounted on the end of the spindle for mounting the cutter row, a driving pulley is mounted on the output shaft of the drive motor, and the driving pulley and the driven pulley are connected by a transmission belt. In the present invention, the driving motor is connected to the spindle via the driving pulley, the driven pulley, and the transmission belt, so that the driving motor drives the spindle to rotate.

[0006] As a further improvement of the present invention, the main shaft is rotatably mounted on the machine base using two bearings. The present invention provides bearings, which reduce the resistance between the main shaft and the machine base, and the two bearings support the main shaft, so that the main shaft is evenly stressed and has good overall stability.

[0007] As a further improvement of the present invention, a plurality of sliding grooves are uniformly formed along the radial direction of the through hole on the end of the pressing disc remote from the main shaft. The calendering wheel bracket is mounted in the sliding grooves and can slide within the sliding grooves. A pressure cover is mounted on the end of the pressing disc where the sliding grooves are formed, for enclosing the pressing disc bracket in the sliding grooves. The present invention provides sliding grooves on the pressing disc to guide the sliding of the calendering wheel bracket on the pressing disc.

[0008] As a further improvement of the present invention, a mounting hole is formed on one end of the calendering roller bracket, away from the centerline of the through hole. A spring is disposed within the mounting hole. The ends of the spring are respectively connected to the bottom of the mounting slot and the calendering plate. The spring expands or contracts as the calendering roller bracket moves within the sliding slot. The spring is provided such that when the calendering roller bracket moves away from the workpiece, the spring is compressed. When the calendering roller bracket moves toward the workpiece, the spring expands, thereby providing power for the movement of the calendering roller bracket.

[0009] As a further improvement of the present invention, a guide groove is defined at each end of the calender roller bracket. A guide pin is disposed in the sliding groove and on the pressure cover. The opposing ends of the two guide pins extend into the two guide grooves, respectively. When the calender roller bracket moves within the sliding groove, the two guide pins move within the two guide grooves, respectively. The present invention, through the cooperation of the guide grooves and the guide pins, not only further guides the movement of the calender roller bracket, but also prevents the calender roller bracket from popping out of the sliding groove.

[0010] As a further improvement of the present invention, a fixing block is installed at one end of the sliding groove away from the center line of the through hole, and one end of the spring is connected to the fixing block. The present invention provides the fixing block to facilitate the fixing of the spring end.

[0011] As a further improvement of the present invention, a calendering wheel mounting groove is formed on one end of the calendering wheel near the centerline of the through hole, and the calendering wheel is rotatably mounted in the calendering wheel mounting groove using a pin. In the present invention, the calendering wheel is rotatably mounted in the calendering wheel mounting groove using the pin, which facilitates installation of the calendering wheel and reduces resistance to rotation of the calendering wheel.

[0012] In summary, the beneficial effects of the present invention are as follows: the present invention grinds and polishes the surface of the workpiece while milling the workpiece, and the grinding is also completed when the workpiece milling is completed, avoiding grinding the workpiece separately and improving the efficiency of the workpiece milling.
