Description

Technical fields:

[0001] This utility model relates to the field of end milling technology for door and window profiles, specifically to a high-efficiency CNC end milling machine. Background technology:

[0002] End milling is an essential process in door and window manufacturing. For example, to assemble mullions with frame profiles, the ends of the mullions are typically milled to create an interface (groove) that matches the frame. A CNC end milling machine is a specialized processing device for milling the ends of door and window profiles. It usually includes a fixture to align and clamp the profile ends, followed by an end milling head. The end milling head can typically perform three translational movements in space to meet the end milling requirements of different profiles. For a specific structure, refer to a single-blade CNC end milling machine for door and window mullions, authorized announcement number: CN208628509U.

[0003] Single-end milling heads often have low working efficiency and cannot meet the requirements of high-efficiency end milling. To address this, existing technologies have also disclosed CNC end milling machines that use multiple end milling heads in combination, such as the high-efficiency CNC end milling machine for door and window mullions disclosed in Chinese Patent No.: CN210588090U. However, most existing multi-end milling head solutions suffer from problems such as large footprint, large mating distance, and large reciprocating stroke, and their processing efficiency needs further improvement.

[0004] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content:

[0005] The purpose of this utility model is to solve the problems existing in the prior art and provide a high-efficiency CNC end milling machine with advantages such as compact and reasonable structural design, small footprint, small reciprocating stroke, flexible combination of four end milling heads, and high end milling efficiency.

[0006] This utility model achieves the above objectives by adopting the following technical solutions:

[0007] A high-efficiency CNC end milling machine includes a base, on which a fixed support and a movable support are respectively provided at the front and rear. The fixed support is fixedly mounted on the base and has a clamp at its upper end. A guide rail is provided on the base along the X-axis, and the movable support is slidably mounted on the guide rail. The movable support includes a movable base plate, on which two vertical plates are spaced apart along the X-axis. A top plate is provided at the upper end of the two vertical plates. An X-axis drive mechanism for moving the movable support is provided on the movable base plate between the two vertical plates. An end positioning mechanism is provided between the two vertical plates. A two-axis translation mechanism is provided on the outer side of the vertical plates. The two-axis translation mechanism moves along the Z-axis and Y-axis. Two end milling heads are vertically spaced apart at the ends of the two-axis translation mechanism. Three of the four end milling heads are fixedly mounted, and the remaining one is rotatably mounted.

[0008] The X-axis drive mechanism includes a reducer mounted on a movable base plate. The reducer has a motor at its input end and a gear at its output end. A rack that meshes with the gear is mounted on the base along the X-axis direction.

[0009] The two-axis translation mechanism adopts a two-axis cross linear module, and a carrier plate is provided at the end of the two-axis translation mechanism. The end milling head is mounted on the carrier plate.

[0010] The end milling head includes a headstock, on which a spindle motor is vertically mounted, and on which an end milling cutter is mounted.

[0011] Two end milling heads are fixedly mounted vertically at intervals on one of the two carrier plates. On the other carrier plate, the upper end milling head is fixedly mounted, and the lower end milling head is mounted on the carrier plate through a rotating mechanism. The rotating mechanism includes a slewing bearing mounted on the carrier plate, and the end milling head is mounted on the slewing bearing. A rotary drive cylinder is rotatably mounted on the carrier plate, and the rotary drive cylinder is rotatably connected to the headstock on the end milling head through a piston rod joint.

[0012] The end positioning mechanism includes a mounting plate connected to two upright plates. An extension plate is provided on the mounting plate. A positioning guide rail is provided on the extension plate along the Y-axis. A positioning slide is slidably provided on the positioning guide rail. A positioning plate is provided on the positioning slide. A positioning drive cylinder is provided between the extension plate and the positioning slide.

[0013] The present invention, by adopting the above-described structure, can bring the following beneficial effects:

[0014] By designing a moving bracket, a compact design of four end milling heads is achieved, while they share the same X-axis movement. The two end milling heads located on one side can be adjusted independently in the Z and Y axes, and one of them can be rotated 90 degrees. This design not only meets the requirements of a compact design, but also fully leverages the advantages of various combinations of end milling heads, which helps to optimize the best end milling solution and significantly improve end milling efficiency.
