A kind of open side type Digit Control Machine Tool that has the cross slid platform workbench
Technical field
The utility model relates to the Computerized Numerical Control processing technology field, particularly a kind of open side type Digit Control Machine Tool that has the cross slid platform workbench.
Background technology
Have the open side type Digit Control Machine Tool of cross slid platform workbench owing to be subjected to the influence of cross sliding table structure, the height of workbench part partly wants high than the workbench of other structure lathes, therefore, under the same conditions, its column height also can correspondingly increase than other structure lathes.Yet, present pillar construction generally all is one-body molded, require under the bigger situation to stroke in lathe entry level or Z, the column of open side type Digit Control Machine Tool that has the cross slid platform workbench is because oversize and very difficult realization processing, on the one hand, process equipment commonly used can not satisfy its dimensional requirement, needs to select the equipment of large scale capacity to process, and has so just increased the production cost of column; On the other hand, because the processing type of column is more, the large scale equipment that has multiple processing type at present is also rarely found, and this equipment often costs an arm and a leg, the general industry and commerce that adds is difficult to bear, and therefore need just can finish its whole processing on multiple different equipment, and this just causes owing to clamping times has too much influenced machining accuracy, and dismounting clamping repeatedly also can reduce the working (machining) efficiency of column, is not suitable for producing in batches.
In addition, the existing open side type Digit Control Machine Tool that has the cross slid platform workbench all is directly to be installed on column on by carriage head, for the processing stand that guarantees head can be covered with whole workbench, that often chain-drive section is done is very big, make main shaft that very big overhanging be arranged, just produce a very big mobile cantilever beam at chain-drive section, like this, increased the weight of head on the one hand, its stability has been caused influence, on the other hand, main shaft is very big with respect to the arm of force of the mobile strong point, is unfavorable for that it keeps higher kinematic accuracy.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of cross slid platform work bench-type open side type Digit Control Machine Tool of being made up of split type column is provided, and under the very big situation of column requirement for height, also is easy to realize its processing; Simultaneously, cantilever beam is arranged on the column, has not only alleviated the weight of head moving-member, also guaranteed the kinematic accuracy of main shaft.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of open side type Digit Control Machine Tool that has the cross slid platform workbench, comprise that lathe bed, column, cross slid platform workbench and main shaft are first-class, the cross slid platform workbench is installed on the lathe bed, can move along front and back and left and right sides both direction; Main tapping is connected on the column by carriage, can vertically move; Wherein, described column is made up of upper pillar stand and lower pillar stand two parts, and upper pillar stand and lower pillar stand are fixedly connected, and lower pillar stand is fixed on the lathe bed, and the cross section of upper pillar stand is the convex shape structure; The point of attachment of described carriage and column is positioned on the convex surface of upper pillar stand.
Above-mentioned a kind of open side type Digit Control Machine Tool that has the cross slid platform workbench, the side of column is provided with automatic tool changer.
Above-mentioned a kind of open side type Digit Control Machine Tool that has the cross slid platform workbench, described upper pillar stand is a hollow structure, and is provided with the reinforcement muscle in upper pillar stand inside.
Above-mentioned a kind of open side type Digit Control Machine Tool that has the cross slid platform workbench, described lower pillar stand is a hollow structure, and at the inside and outside reinforcement muscle that is respectively arranged with of lower pillar stand.
Compared with prior art, the beneficial effects of the utility model are: the utility model adopts the pillar construction form of upper pillar stand and lower pillar stand combination, upper pillar stand and lower pillar stand are processed separately, on common machining center, can finish whole processing, the precision that only needs to guarantee two parts faying face gets final product, and has saved production cost, and has saved clamping link repeatedly, shorten process time, also guaranteed the uniformity of processing; In addition, upper pillar stand adopts the projective table type structure, is about to cantilever beam and has been arranged on the column, cantilever beam is a stationary structure, and stability improves greatly, and has alleviated the weight of head section, reduced the arm of force of main shaft, improved the kinematic accuracy of main shaft with respect to the mobile strong point.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail.
As shown in Figure 1, a kind of open side type Digit Control Machine Tool that has the cross slid platform workbench of the present utility model is made up of lathe bed 1, column 2, cross slid platform workbench 3, main tapping 4, carriage 5 and automatic tool changer 6 etc.Cross slid platform workbench 3 is installed on the lathe bed 1, can carry out all around along the cross slide rail and move; Column 2 is fixed on the lathe bed 1, and places the rear of cross slid platform workbench 3; Main tapping 4 is installed on the column 2 by carriage 5, can move up and down; Be to realize the tool changing automation, be provided with automatic tool changer 6 in a side of column 2.
As shown in Figure 2, column 2 is made up of upper pillar stand 21 and lower pillar stand 22 two parts, and upper pillar stand 21 and lower pillar stand 22 are hollow structure, and has longitudinal rib, radial rib, cross muscle and the sub-muscle of rice etc. to strengthen muscle in the internal placement of upper pillar stand 21 and lower pillar stand 22; The cross section of upper pillar stand 21 is the convex shape structure, and its projecting surface is used to install main tapping 4.During installation, upper pillar stand 21 is fixedly connected with lower pillar stand 22, and lower pillar stand 22 is fixed on the lathe bed 1.
The utility model adopts upper pillar stand and lower pillar stand structure combining form, solved the difficult problem that the high column of traditional integral type is difficult for processing, and last lower pillar stand all adopts hollow structure to add the form of strengthening muscle, when alleviating column weight, also can fully guarantee the rigidity of column.In addition by on upper pillar stand, processing the form of boss, the cantilever beam of cross slid platform work bench-type open side type Digit Control Machine Tool is arranged on the column, solved traditional not high problem of portable cantilever beam stability, and alleviated the weight of head section, reduced the arm of force of main shaft, improved kinematic accuracy with respect to the mobile strong point.
