Abstract
The utility model discloses a milling device which comprises two milling cutters, two fixed shafts, two gears and a rotary driving mechanism, wherein external threads are arranged at cutter shafts of the milling cutters; the two fixed shafts are shaped like hollow cylinders, internal threads matched with the external threads are arranged on the inner surfaces of the fixed shafts, and the cutter shafts of the milling cutters are fixedly arranged on the fixed shafts; the two gears are meshed with each other, and the two fixed shafts are respectively connected with the two gears fixedly; and the rotary driving mechanism is connected with one gear and drives the gear to rotate. According to the utility model, the two milling cutters can work simultaneously, thereby improving the machining efficiency of workpieces. When the end surfaces of the two milling cutters are positioned on two parallel horizontal planes, step surfaces can be directly machined. Through setting a gear ratio of the gear connected with the rotary driving mechanism to the other gear, the milling speed of the two milling cutters can be changed, and the machining to the step surfaces can also be achieved. The milling device is especially applicable to machining of the step surfaces.
Description
Technical field
The utility model relates to a kind of milling attachment.
Background technology
Milling refers to the multiple-cutting-edge tool cutting workpiece that uses rotation, and to work the work piece into needed shape, milling can realize the processing of plane, groove and various forming faces.During milling, main motion is done in the cutter rotation, and workpiece movable is done feed motion; Perhaps workpiece maintains static, and cutter, except rotating, is also done feed motion.Existing milling attachment all only has a cutter, and such design has limited the working (machining) efficiency of milling, and also underaction in use can not meet the needs of various processing.
Summary of the invention
For above-mentioned technical problem, the utility model provides a kind of two milling attachments that milling cutter is worked simultaneously, has improved the working (machining) efficiency of milling.
The technical scheme that the utility model provides is:
A kind of milling attachment comprises:
Two milling cutters, the cutter shaft position of each milling cutter is provided with external screw thread;
Two fixed axis, each fixed axis is hollow tube-shape, and inner surface is provided with the internal thread coordinated with external screw thread, and the cutter shaft of each milling cutter is fixed on each fixed axis;
Two gears that are engaged with each other, described two fixed axis are fixedly connected with two gears respectively;
Rotary drive mechanism, it is connected to one of them gear, drives this gear rotation.
Preferably, in described milling attachment, described two milling cutters are the homonymy setting.
Preferably, in described milling attachment, described two milling cutters are vertical setting, and the end face of two milling cutters is positioned on two parallel horizontal planes.
Preferably, in described milling attachment, an end-enclosed of described each fixed axis, and be provided with Compress Spring in the bottom of each fixed axis, the free end of Compress Spring contacts at the end of the cutter shaft of each milling cutter.
Preferably, in described milling attachment, the gear ratio of the described gear be connected with rotary drive mechanism and another gear is 10:1.
Preferably, in described milling attachment, described rotary drive mechanism is motor.
Milling attachment described in the utility model includes two milling cutters, the cutter shaft of two milling cutters is separately fixed on two fixed axis, and two fixed axis are connected with the gear be engaged with each other again, when rotary drive mechanism is worked, two milling cutters can be worked simultaneously, thereby have improved the working (machining) efficiency of workpiece.When the end face of two milling cutters is positioned on two parallel horizontal planes, just can directly carry out the processing of step surface.By setting the gear be connected with rotary drive mechanism and the gear ratio of another gear, changed the Milling Speed of two milling cutters, also can realize the processing to step surface.The utility model is particularly useful for the machine table terrace.
The accompanying drawing explanation
The structural representation that Fig. 1 is milling attachment described in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, can implements according to this with reference to the specification word to make those skilled in the art.
As shown in Figure 1, the utility model provides a kind of milling attachment, comprising: two milling cutters 5, and the cutter shaft position of each milling cutter is provided with external screw thread; Two fixed axis 4, each fixed axis is hollow tube-shape, and inner surface is provided with the internal thread coordinated with external screw thread, and the cutter shaft of each milling cutter is fixed on each fixed axis; Two gears that are engaged with each other, described two fixed axis are fixedly connected with two gears respectively; Rotary drive mechanism 1, it is connected to one of them gear 2, drives this gear 2 rotations.
In described milling attachment, described two milling cutters are the homonymy setting.
In described milling attachment, described two milling cutters are vertical setting, and the end face of two milling cutters is positioned on two parallel horizontal planes.
In described milling attachment, an end-enclosed of described each fixed axis, and be provided with Compress Spring in the bottom of each fixed axis, the free end of Compress Spring contacts at the end of the cutter shaft of each milling cutter.
In described milling attachment, the described gear be connected with rotary drive mechanism 2 is 10:1 with the gear ratio of another gear 3.
In described milling attachment, described rotary drive mechanism is motor.
Between the cutter shaft of milling cutter and fixed axis, for being threaded, when not needing to use two milling cutters, one of them can be disassembled.Simultaneously, screw thread has the length of one, by screwing in or screwing out milling cutter, can adjust the gap between the end of two milling cutters.
Bottom at fixed axis is provided with Compress Spring, and the free end of Compress Spring is conflicted in the end of cutter shaft, and the vibrations that are subject in process for milling cutter are cushioned and offset, and reduce the loss to milling cutter.
Although embodiment of the present utility model is open as above, but it is not restricted to listed utilization in specification and embodiment, it can be applied to the various fields of the present utility model that are applicable to fully, for those skilled in the art, can easily realize other modification, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend of describing.
