Description
Technical field
The utility model belongs to machine tool technology field, specifically, and the particularly wagon drill Compound Machining mechanism on lathe.
Background technology
At present, piston of automobile part processing excircles and drill centers need to complete by two lathes (two lathes or lathe+mono-drilling machine), and user configured lathe quantity is many so on the one hand, and equipment investment is higher; On the other hand, need clamping twice in process, not only complex operation, can affect working (machining) efficiency, and machining accuracy is also difficult to ensure.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of lathe wagon drill Compound Machining mechanism that can effectively improve working (machining) efficiency, guarantee machining accuracy.
The technical solution of the utility model is as follows: a kind of lathe wagon drill Compound Machining mechanism, in main shaft (1), be equipped with pull bar (2), the left end of this pull bar (2) is connected with the piston rod of angling cylinder (3), the right-hand member of pull bar (2) is connected with hydraulic chuck (5) by drag link sleeve (4), multiple jaws (6) are housed on this hydraulic chuck (5), in described pull bar (2), be equipped with the first drilling rod (7), the left end of this first drilling rod (7) stretches out outside pull bar (2), and the left end of the first drilling rod (7) is connected with the piston of centre drill oil cylinder (8), the right-hand member of described pull bar (2) is connected with the installation end of the second drilling rod (9), the drill bit of the second drilling rod (9) is through hydraulic chuck (5), and be positioned at the center of multiple jaws (6) circumference that surrounds, be set with bearing (10) in the bar portion of described the second drilling rod (9), this bearing (10) is positioned at bearing block (11), the outer circumference surface matched in clearance of the inner ring of bearing (10) and the second drilling rod (9), the outer ring of bearing (10) and bearing block (11) interference fit, described bearing block (11) is fixed on hydraulic chuck (5).
Adopt above technical scheme, piston of automobile part is clamped by the jaw on hydraulic chuck, and main shaft rotarily drives workpiece and rotates, and realizes size processing.The piston of centre drill oil cylinder moves right, and drives the first drilling rod and the second drilling rod to move right, and workpiece rotates under the drive of main shaft simultaneously, thereby realizes drill centers processing.As can be seen here, the utility model can be realized processing automobile outside piston and drill centers on lathe and once complete, and has reduced user and has configured lathe quantity, has greatly improved working (machining) efficiency, has guaranteed better machining accuracy.Between bearing and the second drilling rod cylindrical, it is matched in clearance, with inner hole of bearing seat be interference fit, this fit clearance value and magnitude of interference of strict guarantee in processing, workpiece is in the time that hydraulic chuck rotates, both guaranteed that the first drilling rod and the second drilling rod, not along with rotating (not allowing it to rotate in processing), had guaranteed again shift action and the kinematic accuracy of the second drilling rod.
For simplified structure, convenient for assembly, the piston bush of described centre drill oil cylinder (8) is loaded on the left end of the first drilling rod (7), both threaded engagement, the cylinder body of centre drill oil cylinder (8) is fixed on the headstock of lathe by support bar (12), and support bar (12) parallels with the first drilling rod (7).
For make two drilling rods in conjunction with closely, connect firm, the installation end of described the second drilling rod (9) is ledge structure, the installation end of the second drilling rod (9) stretches in the stepped hole that the first drilling rod (7) right-hand member matches, and the long bolt (13) wearing by center is between the two fixing.
In order to make structure compacter, the left end of described bearing block (11) stretches in the enlarging of drag link sleeve (4) right-hand member, is formed with annular boss at the right-hand member of bearing block (11), and this annular boss fixes by equally distributed screw and hydraulic chuck (5).
Beneficial effect: the utility model only needs clamping once just can realize processing automobile outside piston and drill centers on lathe once to complete, not only reduce user configured lathe quantity, and simple operation, greatly improve working (machining) efficiency, guarantee better machining accuracy.
