Description

Technical Field

[0001] This utility model relates to drilling and milling machine technology, specifically to a multi-head, multi-angle rotary CNC automatic drilling and milling machine. Background Technology

[0002] With the rapid development of modern manufacturing, the complexity and diversity of products are constantly increasing, placing higher demands on the machining accuracy, efficiency, and quality of parts. Traditional drilling and milling equipment, due to its single function and low degree of automation, is unable to meet the machining needs of large-scale, high-precision, and complex-shaped parts.

[0003] Currently, controlled parts are often irregular in shape and have a certain degree of curvature or special cross-sectional shape. When machining them on a drilling and milling machine, it is difficult to find a suitable positioning reference, and the clamping process is also relatively complicated. A lot of time is needed to adjust the position and posture of the parts to ensure machining accuracy. This leads to frequent machine stops for adjustment, reduces the actual machining time of the machine tool, and thus affects machining efficiency.

[0004] Therefore, there is an urgent need for multi-head, multi-angle rotary CNC automatic drilling and milling machines to solve the above problems. Utility Model Content

The clamping process is also relatively complicated, and a lot of time is required to adjust the position and posture of the parts to ensure machining accuracy. This leads to frequent machine stops for adjustment, reduces the actual machining time of the machine tool, and thus affects the machining efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0026] Specifically, one end of the control part is fitted onto the outside of multiple abutment plates 246. By activating the cylinder 241, the active rotating rod 244 will be pushed by the long rod 242. Under the action of this force, the active rotating rod 244 and the driven rotating rod 245 work together to adjust the position of the abutment plate 246 so that the abutment plate 246 can be tightly attached to the inner wall of the part, thus fixing the part.

[0029] This embodiment further defines the support component 3 based on embodiment 1. The support component 3 includes a hydraulic cylinder 31, a long plate 32 and an arc plate 33.

Multiple arc plates 33 are fixedly installed on the top of the long plate 32. The support component 3 also includes a ball bearing 34, which is rotatably installed on the arc surface of the arc plate 33.

[0030] Specifically, the hydraulic cylinder 31 is activated, and its output end drives the long plate 32 to move upward until the ball bearing 34 above the arc plate 33 is in close contact with the part, which can support the part. At the same time, the ball bearing 34 can reduce the friction between the part and the arc plate 33.

[0031] Working principle: In use, the control component is first installed. Specifically, one end of the control component is fitted onto the outside of multiple abutment plates 246. By activating the cylinder 241, the driving rod 244 is pushed by the long rod 242. Under the action of this force, the driving rod 244, together with the driven rod 245, adjusts the position of the abutment plate 246 so that the abutment plate 246 can be tightly pressed against the inner wall of the component, thus fixing the component. Activating the hydraulic cylinder 31 causes its output end to move the long plate 32 upward. When the ball bearing 34 above the arc plate 33 is in close contact with the part, it can support the part. At the same time, the ball bearing 34 can reduce the friction between the part and the arc plate 33. The control center 11 controls the moving center 12 and the processing device 13 to drill holes in the part. While drilling, the drive motor 251 can drive the sleeve rod 243 to rotate through the reduction sprocket group 252. Under the drive of the key block 253 and the keyway 254, the abutment plate 246 and the part can rotate, so as to process and drill holes in different positions of the part.

[0032] The CNC drilling and milling machine for plastic pipes is easy to operate and requires no programming. With its preset program library, graphical interface and one-button start, it is easy to operate and requires no programming. Operators can operate the machine without training.

[0033] This machine is equipped with a four-jaw chuck and can rotate at any angle via CNC setting to achieve automatic rotation and precise circumferential drilling and milling of pipes. This machine combines multiple functions such as drilling, chamfering, milling and grooving, and can realize multiple processing techniques in one machine. In today's situation of high labor costs, it saves a lot of time and doubles work efficiency, making it an ideal tool for batch drilling in large factories.

[0034] This machine adopts advanced CNC technology, enabling continuous drilling of multiple holes in a single clamping. It features a high-torque power head and precision square slide rails to improve efficiency and save labor costs. Whether for small-batch or large-batch production, it can efficiently complete processing tasks.

[0038] To further enhance the machining capabilities and market competitiveness of this machine tool, this utility model also has the following technical advantages:

[0039] Extra-long machining stroke: Overcoming the limitation of ordinary machine tools on the market with a machining stroke length of only 1.5 meters, this machine adopts a new guide rail and structural design to achieve a maximum machining stroke of up to 6 meters, which greatly expands the machining range of long workpieces.

[0040] Multi-head parallel processing: This machine is equipped with 10 drilling and milling heads, which can simultaneously perform multi-point drilling and milling on the same workpiece. Compared with traditional models that are only equipped with a single drilling and milling head and can only process one groove at a time, the processing efficiency is increased by more than 10 times, and the production cycle is significantly shortened.

[0041] Multi-faceted automatic rotation: The machine tool integrates an automatic workpiece rotation function. Through the combined action of the rotating internal support mechanism and the support components, it realizes automatic processing of the tube at different angles and on multiple sides. Only one clamping is required to complete the efficient and fully automatic processing of multiple rows of holes and grooves on the entire tube, while ensuring high-precision positioning.
