Abstract
The invention discloses a boring-rolling composite machining tool for an inner hole of an oil cylinder. The boring-rolling composite machining tool comprises a central spindle and a boring unit on the left end face of the central spindle, wherein a rolling unit, a bearing unit and a support unit are arranged on the outer peripheral face of the central spindle from left to right in sequence; the rolling unit consists of a retainer sleeved on the central spindle with a clearance, and a left roller and a right roller which are arranged on left and right raceways of the retainer; the bearing unit consists of a bearing seat fixedly sleeved on the central spindle, and a thrust bearing on the bearing seat; the support unit consists of a support seat fixedly sleeved on the central spindle, and an elastic support cushion fixedly sleeved on the peripheral face of the support seat; the boring unit comprises a cutter head fixed on the left end face of the central spindle, three slots uniformly distributed in the face of the cutter head along the radial direction, and boring cutters inserted in the slots; a locating mounting hole is formed in the middle part of the face of the cutter head along the axial direction; and an adjusting bolt is arranged inside the locating mounting hole. The boring-rolling composite machining tool has the advantage of ensuring the machining precision of boring.
Description
Technical field
The present invention relates to metal working tool, especially relate to the cylinder bore boring and roll compound cutting tool.
Background technology
At present, the normal manufacturing procedure that adopts has three kinds substantially in cylinder bore processing, and 1, heavy boring-half right boring-right boring-honing; 2, heavy boring-half right boring-right boring-roll extrusion; 3, heavy boring-half right boring-boring is rolled.Above-mentioned manufacturing procedure exists working (machining) efficiency lower, and machining accuracy, the unsettled deficiency of quality are especially particularly outstanding at the cylinder bore below 250 millimeters for diameter.
Summary of the invention
The object of the invention is to provide a kind of cylinder bore boring to roll compound cutting tool.
For achieving the above object, the present invention takes following technical proposals:
Compound cutting tool is rolled in cylinder bore boring of the present invention, comprises mandrel, is arranged on the boring unit on the described mandrel left side; On the mandrel outer peripheral face, be disposed with from left to right roll extrusion unit, bearing unit, support unit; Described roll extrusion unit is sleeved on retainer on the mandrel by the gap, and the left and right roller of spread configuration on the left and right raceway of described retainer forms; Described bearing unit is comprised of the thrust bearing that is fixedly set in the bearing block on the mandrel and be arranged on the described bearing block; Described support unit is comprised of the resiliency supported pad that is fixedly set in the supporting seat on the mandrel and be fixedly set on the described supporting seat side face; Described boring unit comprises the cutterhead that is fixed on the mandrel left side, radially uniform three slots boring cutter interior with being inserted into each slot that is opened on the described cutterhead card; Be positioned at every slot one side in the cutterhead card and be respectively equipped with a boss, on the sidewall of each boss, offer respectively slot corresponding to it screw that communicates and the set bolt of putting in the inner; Offer vertically the location and installation hole at cutterhead card middle part, on the inwall of described location and installation hole, offer respectively the screw that communicates with corresponding slot and the adjustment bolt of putting in the inner corresponding to every slot position place.
Between described retainer and described thrust bearing, be provided with the semicircle adjusting pad.
Described cutterhead is connected with the mandrel left side by flat key and is bolted; The point of a knife that is inserted into boring cutter in three slots is 75 ° of boring cutters distributing of interval 3mm successively vertically.
The invention has the advantages that and uniformly be installed in three on the cutterhead of described mandrel left side boring cutter, and three are positioned at different axial processing planes successively to boring cutter, thereby guaranteed that heavy boring, half right boring, three tooling step of right boring carry out successively, carry out processing for follow-up roll extrusion unit and prepare, thereby greatly improved processing work efficient.For guaranteeing can be normally stable the processing of cutter head, described cutterhead is connected with the mandrel left side by flat key and is bolted, thereby guaranteed that the cutter head boring processes the effective communication of required torque; For satisfying the roll extrusion unit to the requirement of boring unit accurate to dimension, boring cutter is inserted in each slot, adjust and whenever fix the radially processing dimension of boring cutter and by set bolt by adjusting bolt, thereby reach the machining accuracy that guarantees that boring is processed, for follow-up rolling and processing ready; Roll in the process in boring, by increase on right side, roll extrusion unit described support unit reduce boring roll compound tool since the deadweight affect the oil cylinder crudy, improved machining accuracy.
