Description
Technical Field
The utility model belongs to the technical field of the tool changing for the lathe, concretely relates to remove tool arm formula cutter exchange device.
Background
Existing numerically controlled machine tools are usually equipped with a tool magazine: the automatic tool changer comprises a tool bin capable of containing a certain number of tools and an automatic tool changer, and the tools in the tool bin and the tools on the spindle are exchanged under the control of a numerical control system.
One of the most common typical tool magazine formats includes a magazine having a volume, and a set of arm-type automatic tool changers attached to the sides of the magazine. The tool magazine is fixed in position, and the tool changing is completed by moving the main shaft to a specified position. This type of tool magazine is widely used in small and medium size machine tools and works well, but has a number of disadvantages once used in large machine tools.
The large machine tool has large stroke and wide processing area, the tool magazine must be arranged outside the processing area, and the main shaft needs to move by a large stroke to reach the tool changing area during tool changing. When the tool changing action is executed, the main shaft of the machine tool is required to be quickly moved to a tool changing point; because the moving parts of the large machine tool are generally high in mass, the transmission and supporting parts of the machine tool are easy to wear and damage due to the high-frequency and large-stroke rapid movement for the machining requiring frequent tool changing; meanwhile, as the stroke is large, a lot of time is consumed for the spindle to move to a tool changing point and then to transfer to a machining position after tool changing is finished, and the machining efficiency is reduced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a remove tool arm formula cutter exchange device for solve the above-mentioned problem that exists among the prior art.
In order to realize the purpose, the utility model adopts the following technical scheme:
a moving arm tool changer comprising:
the mounting base frame is mounted on the machine tool, and two ends of the mounting base frame are respectively arranged corresponding to the tool magazine and the main shaft of the machine tool;
the supporting and guiding mechanism is arranged on the installation base frame along the length direction of the installation base frame;
the transmission system is arranged on the support guide mechanism and can run along the support guide mechanism;
the transition tool sleeve is arranged on the transmission system and used for temporarily storing the tool to be replaced and the tool taken down from the main shaft; and
and the automatic tool changing arm is arranged on the transmission system and is used for executing the tool inserting, tool pulling and tool changing actions of the tool changing action.
As a specific technical scheme in the utility model, support guiding mechanism and be linear guide, sliding guide or linear bearing.
As a specific technical scheme in the utility model, transmission system is ball screw mechanism, rack and pinion mechanism, cylinder drive mechanism or hydro-cylinder drive mechanism.
Has the beneficial effects that: the automatic tool changing arm of the utility model is completely separated from the tool bin, the automatic tool changing arm is arranged on the movable transmission system, and the transmission system is provided with the transition tool sleeve; and (3) preselecting and pre-exchanging the next procedure near the tool bin by using a tool, exchanging the tool to the transition tool sleeve in advance, and moving the tool to the tool changing point closest to the main shaft to exchange the tool with the main shaft under the matching of the supporting guide mechanism and the transmission system. Because preselection and cutter are exchanged in advance to transition knife sleeve and can go on in step when the last procedure of processing carries out in advance, directly move transition knife sleeve and automatic tool changing arm position to the tool changing point nearest apart from the main shaft again when needing the tool changing, main shaft synchronous motion to tool changing point also simultaneously, will shorten the distance of main shaft and tool changing point under the processing state greatly like this, be favorable to shortening the tool changing time, and reduce the main shaft and frequently carry out long stroke fast moving and to lathe transmission and supporting component wearing and tearing and damage, improve lathe transmission and supporting component reliability and extension lathe precision life-span. When parts needing frequent tool changing are machined on large and medium-sized machine tools, the advantages are obvious, and the service life of the machine tool and the machining rhythm are obviously influenced.

Detailed Description
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the present invention will be briefly described below with reference to the accompanying drawings and the description of the embodiments or the prior art, and it is obvious that the following description of the structure of the accompanying drawings is only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the drawings without any inventive work. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto.
The embodiment is as follows:
as shown in fig. 1, the present embodiment provides a moving arm type tool changer including:
the mounting base frame 1 is used for supporting the whole device, the mounting base frame 1 is mounted on a machine tool, and two ends of the mounting base frame 1 are respectively arranged corresponding to a tool bin 6 and a main shaft 7 of the machine tool;
a supporting and guiding mechanism 2, which is mounted on the mounting base frame 1 along the length direction of the mounting base frame 1, and is used for supporting and guiding the moving parts of the device (such as a transmission system 3 mentioned below); the supporting guide mechanism 2 can be a linear guide rail (such as a BM series ball guide rail produced by Bagger corporation of Shinai Switzerland), a sliding guide rail or a linear bearing (such as an LM-UU series produced by NSK corporation of Japan) and the like, which are all the existing supporting guide mechanisms 2 and have stable structures;
the transmission system 3 is arranged on the support guide mechanism 2 and can run along the support guide mechanism 2; the transmission system 3 can be a ball screw mechanism, a gear rack mechanism, a cylinder transmission mechanism or an oil cylinder transmission mechanism, and the transmission system 3 and the support guide mechanism are in a corresponding matching relationship in a dimensional mode, so that the transmission system 3 can stably run along the support guide mechanism 2 to drive the transition tool sleeve 4 and the automatic tool changing arm 5 below to move;
