Description
Technical field
Gun turret milling machine feeding mechanism the present invention relates to one of mechanical processing industry with interpolation function, specifically one
The gun turret milling machine feeding mechanism of the achievable plane interpolation Milling Process of kind and three-dimensional interpolation Milling Process, is especially applied in milling machine
On numerical control transformation workbench X-axis and the hand feed of workbench Y-axis and auto-feed arbitrarily switch and lifting platform Z axis manually into
It gives in auto-feed switching, it is even more convenient.
Background technique
Currently, milling machine can be widely used for processing plane, at any angle inclined-plane, keyseat, ditch in mechanical processing industry
Slot etc. can also bore, hinge, bore hole.Milling machine table X-axis, Y-axis and lifting platform Z axis should fast move, work feed function
Energy.Fast moving can make workpiece reach Working position rapidly, shorten the non-processing time.The achievable various millings of work feed add
Work.
Traditional milling machine X, Y, Z axis feeding transmission system has purely manual, also has on the right side of the workbench (X-axis), lifting platform
Front side installs automatic feeder additional.Motor and lead screw direct connection will also be fed.The shortcomings that these structures is: structure is relatively multiple
Miscellaneous, at high cost, function is poor, and transmission accuracy is low, and high failure rate, service life is ultrashort, operates time-consuming and laborious.These structures are manual
It is inconvenient on NC postprocessing upgrading with inconvenience in automatic conversion, in the upper inconvenience that meets the market requirement, on modularized production not
Just.
In addition patent No. 1(201710032974.1 in the prior art) disclose a kind of milling machine table X-axis feeding transmission
System structure, the Milling Function which has realization is single, can not achieve the interpolation of slabbing processing
Movement.
In addition patent No. 2(201710032973.7 in the prior art) disclose a kind of milling machine table Y-axis feeding transmission
System structure, the Milling Function which has realization is single, can not achieve the interpolation of slabbing processing
Movement.
In addition patent No. 3(201120095845.5 in the prior art) disclose miniature numerical control drilling and milling machine vertical and horizontal feed machine
Structure compared with the present invention the problem is that, only by cnc mechanism realization automatic function, without manual function, once numerical control function
It can break down, cannot work, insufficiency.
In addition patent No. 4(201410325579.9 in the prior art) disclose tail stock feed arrangement and phase of the present invention
Than the problem is that, motor use direct connection structure, do not increase the function of torque, the outside of lathe is arranged in motor, not beautiful
It sees, takes up space big.
In addition patent No. 5(201420723648.7 in the prior art) disclose a kind of novel vertical CNC milling machine and this hair
It is bright compare the problem is that, only realize automatic function by cnc mechanism, without manual function, once numerical control function occur therefore
Barrier, cannot work, insufficiency.
Therefore, developing a kind of gun turret milling machine feeding mechanism with interpolation function is always new class anxious to be resolved
Topic.

The object of the present invention is to provide a kind of the gun turret milling machine feeding mechanism with interpolation function, invention solution gun turret milling
Bed feed mechanism Milling Function it is single, can not achieve the moving interpolation disadvantage of Milling Process, using manual direct connection structure, it can be achieved that
The gun turret milling machine feeding mechanism of the moving interpolation of slabbing processing, mechanism is provided with deceleration mechanism (gear or belt when automatic
Deceleration transmission), therefore torque is increased, power of motor can be made to reduce, therefore the mechanism saves the energy again, occupies little space, because
Handwheel is directly installed on lead screw, if user does not need power feed, as long as not filling motor when manufacture, therefore is manufactured more square
Just, using the milling machine of the feed mechanism, can hand feed processing again can power feed processing, X-coordinate and Y coordinate cooperate and make
With, it can be achieved that plane interpolation Milling Process, X-coordinate, Y coordinate and Z coordinate are used cooperatively, it can be achieved that the milling of three-dimensional interpolation adds
