Self-pulling type right-angle milling head and multifunctional head comprising self-pulling type right-angle milling head

Abstract

The invention discloses a self-pulling type right-angle milling head and a multifunctional head comprising the self-pulling type right-angle milling head. The self-pulling type right-angle milling head comprises a right-angle milling head body and a sliding pillow end face connecting pad used for being installed with a host interface. Milling head pulling nails are distributed and installed aroundthe lower end face of the sliding pillow end face connecting pad. A pulling nail cap is arranged on the end portion of each milling head pulling nail. Multiple oil cylinder installing grooves are distributed and installed around the periphery of the upper end face of the right-angle milling head body. A pulling head oil cylinder structure used for locking the corresponding pulling nail cap is installed in each oil cylinder installing groove. The self-pulling type right-angle milling head is reasonable in structural design, the structure of the host interface is simplified greatly, all commonplaner type milling machines can obtain a five-face machining function by additionally installing the automatic milling head, and the assembling and arranging cost is low.

Description

technical field [0001] The invention relates to the technical field of numerically controlled milling heads, in particular to a self-pull right-angle milling head and a multifunctional head including the self-pull right-angle milling head. Background technique [0002] It is the strong desire of every machine tool manufacturer and machine user to realize the automatic five-sided machining function of the gantry boring and milling machine. However, most of the gantry machine tools on the market are still bare metal (without any milling head) or low configuration ( Only with manual right-angle milling head) status. The reasons: First, the current automatic milling head has too high requirements for machine tool manufacturers. Even if they do not manufacture the milling head part, they will also put forward high technical requirements for the interface of the ram end face, so for manufacturers with weak technical strength It is very difficult to realize, and it often leads to ...

[0002] It is the strong desire of every machine tool manufacturer and machine user to realize the automatic five-sided machining function of the gantry boring and milling machine. However, most of the gantry machine tools on the market are still bare metal (without any milling head) or low configuration ( Only with manual right-angle milling head) state

The reasons: First, the current automatic milling head has too high requirements for machine tool manufacturers. Even if they do not manufacture the milling head part, they will also put forward high technical requirements for the interface of the ram end face, so for manufacturers with weak technical strength It is very difficult to realize, and it often leads to the incompatibility of the ram between the pentahedron processing machine and the non-pentahedron processing machine, which brings great inconvenience to the production; the second is that the cost is too high. After the five-sided processing machine, the price of the whole machine tool is often greatly increased, which discourages most users! If the user completes some of the necessary types of milling heads (right-angle head, universal head, flat right-angle milling head), it often needs to increase the cost by 400,000-600,000 yuan. The cost ratio is too high

The above is the fundamental reason why five-sided machine tools are not popular at present. From a macro perspective, this is also a great waste of machine tool resources, and at the same time seriously affects the application range and efficiency of all CNC gantry milling machines.

[0003] At present, the interface of traditional pentahedron milling head is as follows: figure 1 As shown, the traditional structure needs to install a relatively complicated traditional ram connection pad 1' on the ram of the main engine. The side wall of the traditional ram connection pad 1' is equipped with a hydraulic quick plug 5', and the upper end face of the traditional right-angle milling head 3' Install the traditional pull stud 4', the traditional pull stud 4' and the traditional slider cylinder 2' installed on the lower end of the traditional ram connection pad 1' are locked and installed, or the internal structure of the ram needs to be changed for the traditional slider cylinder 2' In addition, such a structure often makes the cross-section of the ram relatively large, otherwise there is no way to arrange four traditional slider cylinders 2'. Faced with such a complicated connection structure, ordinary main engine manufacturers want to obtain five-sided processing functions , it is still very difficult, not to mention the manufacturer of the machine tool, not to mention the lack of technical ability, if the host does not consider the use of automatic milling head at all in terms of structure, then the opportunity to install automatic milling head will be completely lost
