Description
Technical field
The utility model relates to drilling machine technical field, relates in particular to a kind of rocking arm self-pulling type drilling machine.
Background technology
Plain radial drilling machine of the prior art is a kind of purposes lathe comparatively widely, can be used for that centering, miniature parts are holed, the work such as reaming, fraising and tapping hole, less workpiece can be arranged on workbench, and larger workpiece can be placed directly on lathe base or ground.It mainly comprises base, column, main spindle box, rocking arm and motor etc., and main spindle box can move on rocking arm, and with rocking arm the drilling machine around column revolving, rocking arm also can move up and down along column, to adapt to process the workpiece of differing heights.As China Patent No. " 200620082455.3 " discloses a kind of Novel radial drilling machine, its open day is on 04 18th, 2007, its technical scheme is that described radial drilling machine comprises workbench, main shaft, be provided with column in workbench one side, on column, arranging can be along the rocking arm of column up-down; on rocking arm, arranging can be along the main shaft cabinet of rocking arm horizontal sliding; above-mentioned rocking arm is provided with horizontal guide rail; main shaft cabinet arranges road wheel; road wheel stand on the upper walking surface of horizontal guide rail, and described horizontal guide rail comprises rail body and removable antifriction metal (AFM) tape; Antifriction metal (AFM) tape is attached in rail body, and the upper horizontal plane of this antifriction metal (AFM) tape is as upper walking surface.
But the prior art taking above-mentioned patent document as representative, in actual use, still exist following defect: one, be connected with column because rocking arm only has one end, and rocking arm can rotate and can move up and down along column around column, this just need to use, and volume is large, quality heavy and the stability of the whole radial drilling machine of column guarantee that rigidity intensity is high, not only cause the difficulty of processing of column large, also cause the cost of column higher.Two, because the weight of rocking arm and main spindle box is heavier, and rocking arm only has end to be set on column, when main spindle box moves on rocking arm and the vibration in main spindle box when work all can increase the pulling force of rocking arm to itself and column junction, the pulling force maximum particularly producing in the time that rocking arm end is worked when main spindle box, this just makes the junction unbalance stress of rocking arm and column, cause rocking arm easily to damage, reduced the service life of whole drilling machine.
Utility model content
The purpose of this utility model is to overcome the above-mentioned problems in the prior art, a kind of rocking arm self-pulling type drilling machine is provided, the utility model makes the junction of rocking arm and column stressed evenly, can strengthen the stability of rocking arm in the time of work, thereby reaches the whole drilling machine of the raising object in service life.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of rocking arm self-pulling type drilling machine, comprise base, column, main spindle box, rocking arm and self-powered platform, column and self-powered platform are all fixed on base, main spindle box is slidably connected on rocking arm; rocking arm and column are rotationally connected, and it is characterized in that: also comprise cross-tie, fixed cover and two steel cables, described fixed cover is rotatably connected on column top; described cross-tie is fixed in fixed cover, and the two ends of described steel cable are connected with the end of rocking arm end and cross-tie respectively.
Top, described rocking arm end is fixedly connected with the vertical pull bar vertical with rocking arm, and described rocking arm is connected with cross-tie with steel cable by vertical pull bar.
Described cross-tie is tapered rod, is inclined at column top, and heavy caliber end and the small-caliber end of described cross-tie lay respectively at fixed cover both sides, and small-caliber end is higher than heavy caliber end, and described steel cable is connected with the small-caliber end of cross-tie.
Employing the utility model has the advantage of:
One, in the utility model, by rotating fixed cover, a cross-tie is set on column top, hold the other end of rocking arm by the cooperation of pull bar and steel cable, not only make rocking arm better in the stability in the time that column rotates, also make the two ends of rocking arm to be supported, the pulling force producing when moving on rocking arm and work because of main spindle box because of main spindle box can be distributed in the support at rocking arm two ends comparatively equably, can either strengthen the stability of rocking arm in the time of work, make the machining accuracy of part higher, can effectively reduce again the spoilage of rocking arm, reach the whole drilling machine of the raising object in service life.Compared with the prior art that is representative with China Patent No. " 200620082455.3 ", because all there is support at the two ends of rocking arm, therefore adopt the column of small volume, lighter weight also can meet use, can effectively reduce the manufacturing cost of column.
Two, in the utility model, top, described rocking arm end is fixedly connected with the vertical pull bar vertical with rocking arm; rocking arm is connected with cross-tie with steel cable by vertical pull bar; because the volume of main spindle box is larger; in order to find processing stand accurately; need transverse shifting main spindle box when processing parts, therefore increases vertical pull bar and can avoid the steel cable tilting to hinder the movement of main spindle box.
Three, in the utility model, described cross-tie is tapered rod, is inclined at column top, and the small-caliber end of cross-tie is higher than heavy caliber end, this structure can prevent that column from tilting, and stablizes under the prerequisite of rocking arm in guarantee, makes the balance of whole column better.
