Abstract
The utility model discloses a quick tool changing device which comprises a tool base and a tool which is installed inside a tool installing cavity of the tool base. The tool base comprises tool chucks and a limiting face, wherein the tool chucks are located around an opening in the bottom of the tool installing cavity, and the limiting face is located at the top inside the tool installing cavity. The tool comprises a plurality of tool bits and a locating face, wherein the tool bits are distributed along the vertical direction, and the locating face is located at the top end. The locating face of the tool is arranged in the tool installing cavity and abuts against the limiting face. The quick tool changing device solves the problems in the prior art and is only composed of two components. The quick tool changing device is low in manufacturing cost and high in practicability.
Description
Technical field
The utility model relates to the electric main shaft rapid changing knife device on CNC milling machine or the grinding machine.
Background technology
Follow the development of numerical control plant equipment, the specification requirement of high density, high-precision numerically controlled processing equipment is more and more higher, efficient and the quality of the digital control processing of the quality of cutter and tool changing direct relation thereof.In known technology, tool changing mainly comprises the steps: 1, the cutter manual load is gone in the knife rest; 2, knife rest clamping cutter moves to reference platform; 3, knife rest relaxed state, cutter falls naturally, the end face touching reference platform of cutter; 4, behind the cutter touching reference platform, finish the action of contraposition, knife rest clamps cutter; 5, the knife rest clamp-on tool is returned to Working position.Be all will move to the operation that reference platform carries out tool setting after each tool changing, increased the working time of board; And need to arrange separately a reference platform space on the lathe and be used for aiming at cutter, increased the volume of board; On the other hand, in middle-size and small-size milling machine tooling, because the profile of some processing parts is complicated, thereby need carry out manual tool changing frequently, tool setting again again not only causes the decline of working (machining) efficiency after the tool changing, and makes operating personnel tired out easily.
Summary of the invention
In order to overcome the deficiency that prior art exists, the purpose of this utility model is to provide a kind of flexibility and reliability, rapid changing knife device simple in structure.
For reaching above purpose, the utility model provides a kind of rapid changing knife device, comprise the base of tool and be installed on cutter within the cutter installation cavity of the described base of tool, the described base of tool comprises the cutter chuck that is positioned at around the cutter installation cavity bottom opening and the confined planes that is positioned at cutter installation cavity inner top, described cutter comprises a plurality of cutter heads of vertically arranging and the locating surface that is positioned at the top, and the locating surface of described cutter is pressing on the described confined planes within the cutter installation cavity.
Further improve as the utility model, also comprise control module, described control module records the height and position information of a plurality of cutter heads respectively and controls the base of tool and move to switch cutter head according to instruction at vertical direction.
Further improve as the utility model, also comprise switch unit, described switch unit is used for according to instructing the described cutter chuck of control to unclamp or clamping to change cutter.
Only the invention has the beneficial effects as follows to be constituted by two assemblies, low cost of manufacture, practicality is stronger.
Description of drawings
Accompanying drawing 1 is the organigram according to rapid changing knife device of the present utility model.
Wherein: 1, cutter; 2, the base of tool; 21, cutter chuck; 22, confined planes; 11, first cutter head; 12, second cutter head; 13, locating surface.
The specific embodiment
Below preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
Shown in accompanying drawing 1, the rapid changing knife device among the figure comprises the base of tool 2, and the base of tool 2 inside have the cutter installation cavity that vertically extends, and is provided with cutter chuck 21 around the cutter installation cavity bottom opening, and cutter installation cavity inner top is provided with confined planes 22.Within the cutter installation cavity of the base of tool 2 cutter 1 is installed, cutter 1 comprises first cutter head 11 that is in the differing heights position and second cutter head 12 of vertically arranging, the top of cutter 1 has locating surface 13, the locating surface 13 of cutter 1 is pressing within the cutter installation cavity on the confined planes 22, and the clamping action by cutter chuck 21 is fixed in cutter 1 within the cutter installation cavity.
Also comprise control module and switch unit in the present embodiment, control module records the height and position information of first cutter head 11 and second cutter head 12 respectively and controls the base of tool 2 and move to switch cutter head according to instruction at vertical direction, and switch unit is used for according to instructing control cutter chuck 21 to unclamp or clamping to change cutter 1.Because with different tool length L1, L2, the endoporus depth H of cutter installation cavity has been carried out standardization, by means of the cutter upper surface location is installed, thereby the tool setting of cutter Z-direction does not change zero point, played the purpose of rapid manual tool changing, the tool setting precision is guaranteed by the tool length tolerance grade.For example in the present embodiment, record the height and position information of first cutter head 11 and second cutter head 12 and control the base of tool 2 and move to switch cutter head according to instruction at vertical direction by control module, thereby realize that different cutters are to the process of part; In addition, even change cutter by switch unit control, new each cutter head positional information of changing cutter of institute moves switch cutter head according to instruction at vertical direction by control module record and the control base of tool 2 equally, owing to only being made of two parts, it is low to have cost, the flexibility and reliability practical characteristics.
Above embodiment only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the people that is familiar with this technology understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this, all equivalences of doing according to the utility model spirit essence change or modification all is encompassed in the protection domain of the present utility model.
