A kind of gantry vertical and horizontal numerically controlled grinder
The present invention relates to the digital control processing field, particularly a kind of multi-functional gantry vertical and horizontal numerically controlled grinder.
Workpiece is owing to be subjected to the restriction of self shape, from under expect and machine, often need to carry out multiple operation processing such as milling, grinding, traditional processing method is that workpiece to be machined is installed in the processing of finishing an operation on a kind of lathe, again it is disassembled from this lathe, clamping is finished the processing of other operations to the other lathe, this not only needs to use many lathes, increase floor space, and in the process of workpiece dismounting and clamping again, certainly exist clamping and position error, machining accuracy is reduced; The process of dismounting and clamping has also influenced working (machining) efficiency simultaneously, has increased production cost virtually, for the big and low product of price request of those processing quantity, is difficult to satisfy processing request.
At present, the grinding machine of being sold on the market mainly contains internal and external grinding machine, surface grinding machine and curve surface grinder, is used for grinding inside and outside circle, plane and curved surface respectively.And the workpiece that need carry out grinding shape more complicated often, various curved surfaces, special-shaped border, hole, groove and die cavity etc. have been comprised, processing for these complicated surfaces, only depend on a grinding machine to be difficult to finish, need so just the problem of above-mentioned machining accuracy, working (machining) efficiency and production cost appear by means of other forms of lathe.
Summary of the invention:
Main purpose of the present invention is to overcome deficiency of the prior art, a kind of simple in structure, multifunctional numerical control grinding machine that machining accuracy is high is provided, both can utilize horizontal main axis to realize the grinding on curved surface, plane, and also can utilize vertical spindle to realize Milling Process such as punching, side cut, chamfering; Vertical spindle also can be installed bistrique simultaneously, realizes upright two grindings of crouching.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
A kind of gantry vertical and horizontal numerically controlled grinder is made up of lathe bed, column, workbench, crossbeam, main shaft etc., wherein, but the cross slide of move left and right is installed on the crossbeam; Cross slide and Z axle sliding floor are slidingly connected; Described main shaft comprises vertical and horizontal two main shafts; Horizontal main axis is fixedly installed in the bottom of Z axle sliding floor; Vertical spindle is installed in the gripping sleeve, and gripping sleeve and Z axle sliding floor are slidingly connected; Simultaneously telescopic cylinder is set above gripping sleeve, cylinder piston and gripping sleeve are fixedly connected.
Described gantry vertical and horizontal numerically controlled grinder, its horizontal main axis are servo principal axis, and its end connects with servomotor, and the other end is installed bistrique; Described vertical spindle is a high-speed electric main shaft; Can bistrique be installed in the vertical spindle lower end, realize upright, two grindings of crouching of lathe; Also can milling cutter be installed on vertical spindle, make Milling Process such as lathe can punch, side cut, chamfering; Simultaneously automatic tool changer is set, can realizes automated production corresponding to vertical spindle.
Compared with prior art, the invention has the beneficial effects as follows: described gantry vertical and horizontal numerically controlled grinder, volume is little, compact conformation is reasonable, on a machine tool, can realize the processing of multiple operation, made things convenient for the making of frock clamp, also save workpiece dismounting and time of clamping again, improved working (machining) efficiency; Also guarantee simultaneously the accuracy of clamping workpiece and location, improved machining accuracy.

The specific embodiment:
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:
In conjunction with Fig. 1, Fig. 2 and shown in Figure 3, gantry vertical and horizontal numerically controlled grinder is made up of lathe bed 1, column 2, workbench 3, crossbeam 4, vertical electric main shaft 5, horizontal main axis 6 etc., but the cross slide 7 of move left and right is installed on the crossbeam 4; Be fixed with guide rail 14 on the Z axle sliding floor 8, a facade of cross slide 7 is slidingly matched mutually with guide rail 14 by slide block 13 and connects, thereby Z axle sliding floor 8 is moved up and down with guide rail 14; Vertical electric main shaft 5 is installed in the gripping sleeve 9, and gripping sleeve 9 is slidingly connected by the fixed guide 16 on slide block 15 and the Z axle sliding floor 8; Simultaneously also be provided with telescopic cylinder 10 above gripping sleeve 9, cylinder piston and gripping sleeve 9 are fixedly connected, and during cylinder 10 work, cylinder piston can drive vertical electric main shaft 5 and move up and down along fixed guide 16; Horizontal main axis 6 is fixedly installed in the below of Z axle sliding floor 8, and the one end connects with servomotor 11, and the other end is installed bistrique 12, during servomotor 11 work, drives bistrique 12 rotations by horizontal main axis 6 and carries out grinding.
As shown in Figure 2, vertical electric main shaft 5 is in the top of fixed guide 16 under the effect of telescopic cylinder 10, and the position of bistrique 12 is lower than the processing end of vertical electric main shaft 5 at this moment, and horizontal main axis 6 work can be carried out the grinding on curved surface, plane or special-shaped border.
As shown in Figure 3, when Milling Process such as needs punch, side cut, chamfering, the piston of telescopic cylinder 10 stretches out, promote vertical electric main shaft 5 move downward to fixed guide 16 bottom, the processing end of vertical electric main shaft 5 is lower than the position of bistrique 12 at this moment, and vertical electric main shaft 5 gets final product work.
For realizing automated production, the automatic tool changer with respect to vertical electric main shaft 5 can be set on gantry vertical and horizontal numerically controlled grinder described in the invention also.
The present invention includes vertical spindle and horizontal main axis, but two main shaft sequential workings, thus realize multiple operation processing, saved the leading time, improved working (machining) efficiency, also improved machining accuracy simultaneously.
