Abstract
The invention relates to a cutter dismounting sleeve and a method using the same for quickly dismounting a cutter, belongs to the field of machine manufacturing, and solves the technical problem that the cutter is difficult to be replaced for a machine tool. The cutter dismounting sleeve comprises a bearing sleeve and a threaded sleeve, the bearing sleeve can sleeve a spindle of the machine tool, the upper end of the bearing sleeve is butted against a spindle mounting base while the lower end of the same is fixedly connected with the threaded sleeve, and an internal thread is matched with an external thread of the cutter. In use, the cutter dismounting sleeve sleeves the cutter, and then is rotated till the cutter of the machine tool is dismounted. The thread of the cutter dismounting sleeve is matched with the processed external thread on the cutter to rotate, mutual acting force between the spindle mounting base and the cutter dismounting sleeve are fully utilized to draw the cutter out of a spindle hole of the machine tool, the cutter dismounting sleeve is simple in structure and has high practical value in machine manufacturing and machining, damage to the cutter and the spindle mounting base is avoided in the cutter replacement process, and machining accuracy of the machine tool is guaranteed indirectly.
Description
Technical field
The invention belongs to mechanical manufacturing field, be specifically related to a kind of equipment that lathe, lathe etc. have been installed to cutter and unload fast cutter and method.
Background technology
Along with manufacturing development,, in greatly having promoted working (machining) efficiency, also there are some minor issues in a large amount of uses of the plant equipment such as lathe, lathe.In machining, conventionally need to be on lathe mounting cutter, normally cutter is packed into the spindle hole with tapering of lathe, then cutter is fixing and post-tensioning screw rod fixes vertical machine knife, conventionally complete after processing tasks, the reason of active force during due to processing work, cutter will be firmly secured in machine tool chief axis hole, when tool changing in the time unclamping the nut of post-tensioning screw rod, need to knock energetically screw rod tail, cutter is deviate from from spindle hole, complete the process of tool changing, this process is brought great inconvenience to tool changing person, the strength that processor short and small for height or that health is comparatively thin and weak will use whole body, sometimes also to stand on workbench and go to complete the process that cutter is drawn off to spindle hole, at needs comparatively frequently tool changing in the situation that, be inconvenient to greatly reduce production efficiency because of tool changing, the process that this rough power of this external application is unloaded cutter, the spindle hole of cutter and mounting cutter is all had to the infringement of distortion, affect the machining accuracy of lathe after tool changing.
Summary of the invention
For solving the technical problem of above-mentioned lathe tool changing tool difficulty, the invention provides a kind of vigor, unload cutter method easily and efficiently.
One is unloaded broach shell, it is characterized in that: comprise load sleeve and screw shell, described load sleeve can be enclosed within on the main shaft of lathe, and upper end is against on main shaft mount pad, and lower end is fixedly connected with screw shell, and described internal thread and the external screw thread of cutter match.
A method of unloading fast cutter, comprises following steps:
A. on cutter, process external screw thread;
B. process with cutter matches and unload broach shell;
C. in the time that needs unload cutter, will unload broach shell and be enclosed within on cutter, in the time arriving screw position, rotary unloading broach shell;
D. unload broach shell and rotate to load sleeve and be against after main shaft mount pad and continue rotation, until the cutter of lathe is removed.
The present invention coordinates rotation by the screw thread that unloads broach shell with the external screw thread of processing on cutter, and make full use of the main shaft mount pad of lathe and unload interactional power between broach shell, cutter is extracted to the spindle hole of lathe, simple in structure, in machine-building and processing, there is higher practical value, can greatly improve the operating efficiency of tool changing tool, in addition, by this device and method, avoid the infringement to cutter and main shaft mount pad in cutter changing process, indirectly ensure machine finish.
Brief description of the drawings
Drawing of the present invention is described as follows:
Fig. 1: unload the installation of broach shell and use schematic diagram;
Fig. 2: the cutter schematic diagram that unloads of the prior art;
Fig. 3: the structural representation that unloads broach shell;
In figure: 1. nut 2. main shaft mount pads 3. unload broach shell 4. cutter 5. post-tensioning screw rods
Detailed description of the invention
Below in conjunction with accompanying drawing, that the present invention is further illustrated is as follows:
One is unloaded broach shell, it is characterized in that: comprise load sleeve and screw shell, described load sleeve can be enclosed within on the main shaft of lathe, and upper end is against on main shaft mount pad 2, and lower end is fixedly connected with screw shell, and described internal thread and the external screw thread of cutter match.
More convenient for making to unload the use of broach shell, be installed with handle outward unloading broach shell, handle can drive and unload broach shell rotation.
A method of unloading fast cutter, comprises following steps:
A. on cutter 4, process external screw thread;
B. process with cutter matches and unload broach shell 3;
C. in the time that needs unload cutter, will unload broach shell 3 and be enclosed within on cutter 4, in the time arriving the screw position of cutter 4, rotary unloading broach shell;
D. unload broach shell 3 and rotate to load sleeve and be against the rear continuation of main shaft mount pad 2 rotation, until the cutter 4 of lathe is removed.
Before machine tooling, cutter 4 need to be arranged in spindle mounting hole, and screw in after cutter 4 with post-tensioning screw rod 5, the nut 1 of rotation post-tensioning screw rod tail end is fixed cutter.After machine tooling completes, back out nut 1, pack into and unload broach shell 3, rotary unloading broach shell 3, is against on main shaft mount pad its load sleeve, continues rotation, coordinates with the externally threaded of cutter by the screw thread that unloads broach shell 3, unloads bottom tool.
Protection scope of the present invention is not limited only to the disclosed technical scheme of detailed description of the invention part, all utilized with cutter on the screw thread rotation mode that matches of the external screw thread processed realize the device and method that unloads cutter and all fall into protection scope of the present invention.
Claims (3)
1. one kind is unloaded broach shell, it is characterized in that: comprise load sleeve and screw shell, described load sleeve can be enclosed within on the main shaft of lathe, upper end is against on main shaft mount pad (2), lower end is fixedly connected with screw shell, and described internal thread and the external screw thread of cutter match.
2. the broach shell that unloads according to claim 1, is characterized in that: be installed with handle outward unloading broach shell, handle can drive and unload broach shell rotation.
