Description
Technical field
The utility model is related to machine tool technology field, relates in particular to a kind of tool holder micrometer feed device.
Background technology
Tool holder is that the fretting performance of tool holder is that lathe or complex milling machine tool precision are critically important for clamping lathe tool
An index.The feeding of the tool holder of general lathe is to use screw rod transmission, and the precision of its amount of feeding receives wire rod thread helical pitch
Limitation, it is it is difficult to accomplish small feeding and high to the processing request of wire rod thread, so the fretting performance of existing tool holder
It is difficult to improve at low cost.
The content of the invention
The technical problems to be solved in the utility model is to provide the good tool holder of a kind of easy processing, low cost, fretting performance
Micrometer feed device.
In order to solve the above technical problems, the utility model is adopted the technical scheme that：
A kind of tool holder micrometer feed device, including：
One screw mandrel, the screw mandrel has two sections of screw threads, and the rotation direction of two sections of screw threads is identical, helical pitch is different；
One fixing nut, the fixing nut is arranged on the screw mandrel, with larger section of threaded adapter of helical pitch in the screw mandrel；
One traveling nut, the traveling nut is arranged on the screw mandrel, with helical pitch in the screw mandrel compared with segment threaded adapter；
Tool holder is installed on the traveling nut；
One line slide rail, the line slide rail is arranged in an axially parallel mode along the screw mandrel, and the traveling nut passes through slide nut
Block is slidably connected with the line slide rail；
One motor, the rotation output section of the motor is affixed with the screw mandrel.
Working method of the present utility model is：Motor drive screw mandrel rotate, screw mandrel in fixing nut with helical pitch compared with
The helical pitch feeding of big section screw thread, now, helical pitch feed reversing of the traveling nut with respect to screw mandrel with helical pitch compared with segment screw thread, then,
The final amount of feeding of traveling nut is the product that two sections of differences of lead rotate the number of turns with screw mandrel.
Therefore, the difference of two sections of helical pitches of screw thread is smaller, and the amount of feeding of traveling nut is smaller, and tool holder is got over can realize fine motion,
And the action response of tool holder can be smoothed out very much；Wire rod thread helical pitch need not be worked into very little in itself, to the processing of screw mandrel just
It is easier, processing cost also can be than relatively low.So, the spy such as the utility model has easy processing, low cost, fretting performance good
Point.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Each label is respectively in figure：
（1）Screw mandrel,（2）Fixing nut,（3）Traveling nut,（4）Line slide rail,（5）Motor,（6）Epimere screw thread,
（7）Hypomere screw thread,（8）Body of milling head,（9）Tool holder,（10）Nut slider.
Specific embodiment
To describe technology contents of the present utility model, structural feature, the objects and the effects in detail, below in conjunction with implementation
Mode simultaneously coordinates accompanying drawing to be explained in detail.
Referring to Fig. 1, a kind of tool holder micrometer feed device of the utility model can be applicable on milling machine, make turnning and milling
Combined machine, the tool holder micrometer feed device includes screw mandrel 1, fixing nut 2, traveling nut 3, line slide rail 4 and drives electricity
Machine 5.Screw mandrel 1 is vertically arranged, and screw mandrel 1 has the rotation direction phase of epimere screw thread 6 and hypomere screw thread 7, epimere screw thread 6 and hypomere screw thread 7
Together, helical pitch of the helical pitch of epimere screw thread 6 more than hypomere screw thread 7.Fixing nut 2 is arranged on screw mandrel 1 and is fixed on body of milling head 8,
Fixing nut 2 is adapted with the epimere screw thread 6 of screw mandrel 1.Traveling nut 3 is arranged on screw mandrel 1, the phase of hypomere screw thread 7 with screw mandrel 1
Adaptation；Tool holder 9 is also equipped with traveling nut 3, tool holder 9 is used to install lathe tool.Line slide rail 4 is vertically set on body of milling head
It is axially in parallel with screw mandrel 1 on 8；Traveling nut 3 is slidably connected by nut slider 10 with line slide rail 4.Motor 5
Rotate output section affixed with the upper end of screw mandrel 1, motor 5 also can form the company of slip by motor sliding block and line slide rail 4
Connect.
When 5 drive screw of motor 1 is rotated, screw mandrel 1 is together relatively fixed nut 2 and feeds with motor 5, meanwhile,
Because fixing nut 2, traveling nut 3 are located on two sections of screw threads that rotation direction is identical but helical pitch is different of screw mandrel 1 respectively, therefore movable screw
Female 3 will be along line slide rail 4 with respect to the feed reversing of screw mandrel 1, in this way, the actual feeding of traveling nut 3 equipped with tool holder 9 is two sections of spiral shells
The difference of the helical pitch of line, then, in the case where the processing request to the lead of screw mandrel 1 is not high, tool holder 9 just realizes high-precision
Degree ground fine motion, and start and stop smooth-going so that tool holder 9 is provided with very good fretting performance.
The above, is only a kind of preferred embodiment of the utility model, not to technical scope of the present utility model
Impose any restrictions, every any trickle amendment, equivalent change made to above example according to technical spirit of the present utility model
Change and modify, still fall within the range of the utility model technology.
