Description

A kind of numerically control grinder

Technical field

The utility model relates to a kind of Computerized Numerical Control processing technology, relates in particular to a kind of numerically control grinder.

Background technology

Numerically control grinder is to utilize grinding tool surface of the work to be carried out the lathe of grinding.Most grinding machine is to use the emery wheel of at a high speed rotation to carry out grinding, and be to use other grinding tools such as oilstone, abrasive band and the free abrasive of minority are processed, as honing machine, superfinisher, abrasive belt grinding machine, grinder and polishing machine etc.Numerically control grinder has numerical control plane grinding machine, numerical control centerless grinder, numerical control internal and external grinding machine, digital control vertical grinding machine of universal, CNC jig grinding machine, numerical control formation grinding machine etc. again.

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.

The utility model content

The utility model corrects at above-mentioned problems, a kind of simple in structure, multifunctional numerical control grinding machine that machining accuracy is high is provided, it both can utilize horizontal main axis to realize the grinding on curved surface, plane, 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.

Concrete technical scheme is:

A kind of numerically control grinder, it comprises lathe bed, column, workbench, crossbeam and main shaft, and the cross slide of move left and right is installed on the described crossbeam; Described cross slide and Z axle sliding floor are slidingly connected; Described main shaft comprises vertical and horizontal two main shafts; Described horizontal main axis is fixedly installed in the bottom of described Z axle sliding floor; Described vertical spindle is installed in the gripping sleeve, and described gripping sleeve and described Z axle sliding floor are slidingly connected; Telescopic cylinder is set above gripping sleeve simultaneously, cylinder piston and gripping sleeve are fixedly connected, the utility model 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.

Described crossbeam is installed on the guide rail take-up housing, X is arranged to transmission mechanism on the described guide rail take-up housing, and link to each other with the guide rail base upper rail, described guide rail one side is one group of two linear rolling track, one side is the roller type rolling guide, or two sides are linear rolling track.The crossbeam of grinding machine is directly installed on the guide rail take-up housing, and structure is simple and clear, and center of gravity is low, and kinetic stability is good, and precision is good.Grinder head can be made shaping grinding and peripheral grinding, and function of use is many, can realize automatic grinding, is a kind of novel accurate grinding process equipment.

The specific embodiment

Describe the utility model by the following examples, should be noted that, cited embodiment should not understand the restriction to utility model.

As shown in the figure: the present embodiment numerically control 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 2 sliding floors 8, a facade of cross slide 7 is slidingly matched mutually with guide rail 14 by slide block 13 and connects, thereby 2 sliding floors 8 are 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 2 sliding floors 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 2 sliding floors 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.

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, this moment, the processing end of vertical electric main shaft 5 was lower than the position of bistrique 12, vertical electric main shaft 5 gets final product work.

Present embodiment comprises 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.

Obviously; foregoing is just in order to illustrate characteristics of the present utility model; and be not to restriction of the present utility model, the variation that the those of ordinary skill in relevant technologies field is made in the corresponding techniques field according to the utility model should belong to protection category of the present utility model.
