Description
Technical field
The utility model relates to drilling machine technical field, and relating in particular to a kind of base is semicircular radial 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 the workpiece of processing 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, in workbench one side, be provided with column, 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, it is characterized in that: 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 that the above-mentioned patent document of take is representative, in actual use, still exist following defect: one, because rocking arm only has one end, be connected with column, 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 when 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, it is semicircular radial drilling machine that a kind of base is provided, the utility model makes the junction of rocking arm and column stressed evenly, can strengthen the stability of rocking arm when work, thereby reach 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 base is semicircular radial drilling machine, it is characterized in that: comprise semi-circular base, lifting platform, head tree, auxiliary column, steady pin, main spindle box and rocking arm, in described semi-circular base, be provided with a semicircle chute, on the sidewall of described chute, be evenly provided with a plurality of fixing holes, described head tree is fixedly installed on the circle centre position of semi-circular base, described auxiliary column is slidably arranged in chute, on described auxiliary column, be provided with spacing hole, described main spindle box and rocking arm are slidably connected, one end and the head tree of described rocking arm are rotationally connected, the other end is fixedly connected with auxiliary column, described lifting platform is arranged on the rocking arm below between head tree and auxiliary column, during work, described steady pin is fixed on auxiliary column in chute through fixing hole and spacing hole successively.
Described lifting platform is comprised of square mesa and four self-locking jack, and described square mesa is arranged on base by four self-locking jack.
Employing the utility model has the advantage of:
One, in the utility model, because head tree is arranged on the center of semi-circular base, auxiliary column is arranged in semicircle chute, therefore coordinating by auxiliary column and head tree, the pulling force that can produce when moving on rocking arm because of main spindle box and working because of main spindle box is distributed to the junction of rocking arm and head tree, rocking arm and auxiliary column comparatively equably, can effectively reduce the spoilage of rocking arm, thereby reach the whole drilling machine of the raising object in service life.By lifting platform, can adjust to correct position by be processed, be conducive to processing.When main spindle box is started working, auxiliary column is fixed in chute by steady pin, and this structure can prevent that auxiliary column is shifted, and makes the stability of rocking arm when work better, is conducive to improve the machining accuracy of part.Compare for the prior art of representative with China Patent No. " 200620082455.3 ", because the two ends of rocking arm all can be supported, 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, because having, self-locking jack can support heavy workpiece and the speed stable advantage of jacking, and better to the supportive of workpiece when regulating workpiece height, therefore adopt self-locking jack to make the stability of workpiece on table top better.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Being labeled as in figure: 1, semi-circular base, 2, head tree, 3, auxiliary column, 4, main spindle box, 5, rocking arm, 6, steady pin, 7, chute, 8, table top, 9, self-locking jack, 10, roller.
