Description

Technical Field

[0001] This utility model relates to the field of machining parts technology, and more specifically, to a side milling head device. Background Technology

[0002] A side milling head is a machine tool accessory that allows the tool's rotation center line to be angled with the spindle's rotation center line for machining workpieces. It is now widely used in various fields of machining, including aerospace, automotive, and mold making. Using a side milling head increases the machining range and adaptability of the machine tool without altering its structure, enabling machining operations that are difficult to perform using traditional methods. It also reduces the need for repeated workpiece clamping, improving machining accuracy and efficiency.

[0003] During the machining process of a side milling head, the side milling head generates a lot of heat, which requires the use of cutting fluid for cooling. Traditional side milling head devices have cutting fluid nozzles that are mostly located externally, and the spray direction of the cutting fluid nozzles is difficult to adjust, and there is also the problem that the nozzles can easily touch the workpiece being machined.

[0004] In addition, traditional side milling head devices are difficult to maintain after leaving the factory. With prolonged use, the internal gears and bearings will wear out more quickly, which will greatly reduce the service life of the side milling head device and thus increase the operating cost of the side milling head device.

[0005] Meanwhile, for machining workpieces with small inner diameters, traditional side milling heads also need to be reduced in size. However, due to the small internal gear size and module of small-sized side milling heads, the rated output torque is far from sufficient, and the machining strength cannot meet the requirements for machining hard materials. Although increasing the gear size of traditional side milling heads can solve the machining strength problem, the increased size still makes it impossible to machine workpieces with small inner diameters.

[0006] The purpose of this invention is to overcome the shortcomings and deficiencies of the prior art and provide a side milling head device. This side milling head device can not only adjust the direction of cutting fluid injection according to processing requirements, but also facilitate internal cooling of the side milling head device. This invention also provides a side milling head device that can reduce the wear of internal components, thereby extending the service life of the side milling head device and reducing its operating costs.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a side milling head device, characterized in that: it includes a main body, a driving component, a transmission component, and a side milling component with a cutting tool; the transmission component is disposed inside the main body and connected to the side milling component; the side milling component is located inside the main body and rotatably disposed on the main body, with the cutting tool extending out of the main body, and the cutting tool serving as a machining station; the driving component is connected to the main body and connected to the transmission component, thereby realizing the rotation of the cutting tool of the side milling component through the transmission component;

[0008] The side milling head device also includes a cutting fluid inlet and an adjustable spray nozzle. The main body is provided with a cutting fluid delivery channel, one end of which is connected to the cutting fluid inlet and the other end is connected to the nozzle. The nozzle is mounted on the main body and the spray direction of the nozzle is towards the machining station.

[0009] In the above-described design, when the cutting tool rotates to process the workpiece, the direction of the cutting fluid spray from the nozzle can be adjusted according to the processing requirements to achieve accurate and effective cooling of the workpiece. Furthermore, the cutting fluid delivery channel is located inside the main body, which can also cool the interior of the main body, thereby extending the service life of the side milling head device.

[0010] The conveyor channel is a passageway opened inside the main body. This design simplifies the structure of the side milling head device.

[0011] The nozzle is a spherical nozzle. The spherical nozzle allows for easy adjustment of the spray direction and eliminates the problem of contact with the workpiece during processing.

[0012] The side milling head device also includes at least one oiling component; the oiling component is disposed on the main body, with one end connected to the outside and the other end extending into the transmission component. This invention provides an oiling component to facilitate routine oiling and maintenance of gears and bearings, effectively reducing wear on gears and bearings, thereby extending the service life of the side milling head device and reducing its operating costs.

[0013] The oil injection assembly includes an oil delivery channel and an oil injection nozzle; the oil injection nozzle is disposed on the main body; the oil delivery channel is a channel opened inside the main body, one end of the oil delivery channel is connected to the oil injection nozzle, and the other end faces the transmission assembly.

This utility model solves the problem of difficult installation due to limited space by using fasteners to press the cutter against the side.

[0016] The upper part of the cutter barrel shaft has an umbrella-shaped structure; a sealing ring is provided at the step of the cutter barrel shaft. The umbrella-shaped structure at the upper part of the cutter barrel shaft of this invention allows a large amount of cutting fluid to be thrown out, preventing cutting fluid from entering the side milling head device, and the sealing ring can further improve the sealing performance.

[0017] The drive assembly includes a drive component and a mounting base; the mounting base is connected to the main body, and the cutting fluid inlet is located on the mounting base; the drive component is connected to the transmission assembly to enable the drive transmission assembly to work.

This significantly reduces the size of the side milling head device, making it suitable for processing workpieces with small inner diameters. Furthermore, the use of a spur gear set increases the gear module, resulting in greater processing strength for the side milling head device, enabling it to meet the processing requirements of hard materials.

Detailed Implementation

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Example

[0033] like Figures 1 to 6 As shown, the side milling head device of this utility model includes a main body 1, a drive assembly, a transmission assembly, and a side milling assembly with a cutting tool 2.
