A kind of NC vertical lathe with two-sided cutting function
Technical field
The utility model relates to a kind of machining equipment, is specifically related to vertical lathe, relates in particular to a kind of NC vertical lathe with two-sided cutting function.
Background technology
Vertical lathe is that a kind of main shaft arranges that vertically workbench rotates in horizontal plane, and knife rest is made the lathe of vertical or oblique feeding, is mainly used in the workpiece that short large-scale, the heavy type of big, the length of processing diameter etc. is difficult for clamping on horizontal lathe.
The structure of existing vertical lathe comprises a pedestal; Along continuous straight runs is provided with a rotary table on this pedestal; On the said pedestal vertically (being Z-direction) also be provided with a column, be installed with a crossbeam on this column, this crossbeam upper edge X-direction sliding seat that is slidingly connected; This sliding seat upper edge Z-direction slide post that is slidingly connected, the lower end of said slide post has a processing head.During work, at first that clamping workpiece is fixing on workbench, control said sliding seat then said slide post is moved to the workpiece top, control said slide post again and move up and down said processing head, it is contacted, the beginning manufacturing procedure with surface of the work.Yet this existing vertical lathe finds to exist following problem in actual use: when the processing flat workpiece (like brake disc etc.), often need two faces of workpiece all be cut; Therefore on operation, need twice clamping, twice location be arranged to workpiece; In addition, when cutting, because the reason of the section bar characteristic (like intensity, toughness) of workpiece itself; Possibly when stressed, produce distortion; So can bring the workpiece depth of parallelism that processes poor, can produce the problem of machining accuracy aspects such as thin and thick is poor, end face run-out, and production capacity be lower.
Therefore, how to solve the deficiency that above-mentioned prior art exists, just become the utility model the problem that will study.
Summary of the invention
The purpose of the utility model provides a kind of NC vertical lathe with two-sided cutting function, to solve the problem that machining accuracy is low and production capacity is lower that existing vertical lathe can produce when the processing flat workpiece.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of NC vertical lathe with two-sided cutting function comprises a pedestal; Along continuous straight runs is established a rotary table on this pedestal; Said pedestal upper edge Z-direction also is provided with a column, and this column is provided with a crossbeam, this crossbeam upper edge X-direction sliding seat that is slidingly connected; This sliding seat upper edge Z-direction one first slide post that is slidingly connected, and the lower end of this first slide post has one first processing head; Wherein: said sliding seat upper edge Z-direction also slidely connects one second slide post, and this second slide post is parallel with said first slide post side by side; The lower end of said second slide post has one second processing head, and the application point of the application point of this second processing head and said first processing head is oppositely arranged on Z-direction; Effect has a drive unit on said second slide post; This drive unit comprises ball screw and motor; Said motor is fixedly arranged on the said sliding seat, and said ball screw is made up of screw rod, nut and ball, and said screw rod axially is provided with along Z; The output shaft of one of which end and said motor is in transmission connection, and said nut is fixedly connected with second slide post.
Related content in the technique scheme is explained as follows:
1. in the such scheme, said processing head is a cutter.
The utility model operation principle and advantage are following:
A kind of NC vertical lathe of the utility model with two-sided cutting function; Through Z-direction one second slide post that is slidingly connected in the sliding seat upper edge of original lathe; The lower end of this second slide post has one second cutter, and the application point of first cutter is oppositely arranged on this second cutter and first slide post, and effect has a drive unit on this second slide post; Make the utility model against existing technologies with this, the machining accuracy and the production capacity of flat workpiece all is greatly improved.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model embodiment.
In the above accompanying drawing: 1. pedestal; 2. rotary table; 3. column; 4. crossbeam; 5. sliding seat; 6. first slide post; 7. first cutter; 8. second slide post; 9. second cutter; 10. motor; 11. screw rod.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Embodiment: shown in accompanying drawing 1, a kind of NC vertical lathe with two-sided cutting function comprises:
One pedestal 1; Along continuous straight runs is established a rotary table 2 on this pedestal 1; Said pedestal 1 upper edge Z-direction also is provided with a column 3, and this column 3 is provided with a crossbeam 4, these crossbeam 4 upper edge X-directions sliding seat 5 that is slidingly connected; These sliding seat 5 upper edge Z-directions one first slide post 6 that is slidingly connected, and the lower end of this first slide post 6 has one first cutter 7; Wherein: said sliding seat 5 upper edge Z-directions also slidely connect one second slide post 8, and this second slide post 8 is parallel arranged side by side with said first slide post 6; The lower end of said second slide post 8 has one second cutter 9, and the application point of the application point of this second cutter 9 and said first cutter 7 is oppositely arranged on Z-direction.
Effect has a drive unit on said second slide post 8; This drive unit comprises ball screw and motor 10; Said motor 10 is fixedly arranged on the said sliding seat 5, and said ball screw constitutes (among nut and the ball figure sign) by screw rod 11, nut and ball, and said screw rod 11 axially is provided with along Z; The output shaft of one of which end and said motor 10 is in transmission connection, and said nut is fixedly connected with second slide post 8.
When workpiece is carried out two-sided cut, at first, with clamping workpiece on said rotary table 2; Secondly; Move said sliding seat 5 first cutter 7 of said first slide post 6 and second cutter 9 of said second slide post 8 are moved near the workpiece place, distance controls to the degree that is slightly larger than thickness of workpiece between the application point of the application point of first cutter 7 and second cutter 9 simultaneously, then; First cutter 7 and second cutter 9 are moved to the workpiece place; The one side of first cutter, 7 corresponding workpiece, 9 pairs of another sides of second cutter with workpiece, last; With fit two surfaces of workpiece of action head, so far the preparation of the two-sided cut of workpiece finishes respectively for said first cutter 7 and second cutter 9.
A kind of NC vertical lathe of the utility model with two-sided cutting function; Through Z-direction one second slide post that is slidingly connected in the sliding seat upper edge of original lathe; The lower end of this second slide post has one second cutter, and the application point of first cutter is oppositely arranged on this second cutter and first slide post, and effect has a drive unit on this second slide post; Make the utility model against existing technologies with this, the machining accuracy and the production capacity of flat workpiece all is greatly improved.
The foregoing description only is the technical conceive and the characteristics of explanation the utility model, and its purpose is to let the personage who is familiar with this technology can understand content of the utility model and enforcement according to this, can not limit the protection domain of the utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection domain of the utility model.
