Description

Technical Field

[0001] This utility model relates to the field of milling equipment technology, specifically to an angle milling head with increased working stroke. Background Technology

[0002] Angle milling heads, as machine tool accessories that can change the tool tilt angle to machine the sides, slopes, and complex curved surfaces of workpieces, have technological origins that can be traced back to the early era of machining. With the continuous development of the machinery manufacturing industry, the requirements for machining accuracy, efficiency, and flexibility have been increasing. Angle milling head technology has also undergone a development process from simple to complex, from manual to automatic, and from single-function to multi-function.

[0003] The existing technology still has the following drawbacks in its use: In existing technologies, angle milling heads typically employ a pair of spiral bevel gears for continuous transmission, which restricts machine tool travel and limits machining space. This necessitates the use of equipment with larger travel ranges for many workpieces, resulting in increased power consumption and significant resource waste due to equipment downtime. To address this, our company has developed a series of offset output side milling heads to increase the machine tool cutting range, improve equipment utilization, and reduce power consumption.

[0004] In view of this, we propose an angle milling head with increased working stroke to solve the existing problems. Summary of the Invention

[0005] The purpose of this invention is to provide an angle milling head with increased working stroke to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an angle milling head with increased working stroke, including a drive tool holder, a housing connected to the rear end of the drive tool holder, a rear cover provided at the upper end of the housing, multiple sets of shaft gears installed inside the rear cover, a first horizontal shaft gear connected to the shaft gear on the side near the drive tool holder, a second horizontal shaft gear connected to the shaft gear on the side away from the drive tool holder, a first horizontal shaft installed at the center of the first horizontal shaft gear, a second horizontal shaft installed at the center of the second horizontal shaft gear, a first arc bevel gear installed at the bottom of the first horizontal shaft, the first arc bevel gear meshing with the second arc bevel gear, and the second arc bevel gear installed inside the drive tool holder.

[0007] Preferably, multiple sets of bearing components are installed on the outer ring of the first horizontal shaft, and a bearing cap is installed on the upper end of each bearing component.

[0008] Preferably, an output shaft is provided at the lower end of the second horizontal axis, and a connecting mechanism is installed inside the output shaft.

[0009] Preferably, bearings are installed at both the upper and lower ends of the gear with shaft.

[0010] Preferably, a first threaded cap is provided at the upper end of the rear cover near the first horizontal axis, and a second threaded cap is provided at the upper end of the rear cover near the second horizontal axis.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention extends the power output gear in a direction offset from the tool center by extending the drive shaft of the angle milling head, and then uses a planar gear to output power to the tool clamping output shaft. This makes the tool clamping part larger than the spindle centerline, thereby increasing the effective cutting space of the machine tool. Attached Figure Description
