Abstract

The utility model discloses a cylinder-bore boring and rolling device, which comprises a mandrel body, wherein a boring portion, a rolling portion, a supporting portion are sequentially left-to-right arranged on the periphery surface of the mandrel body. The boring portion comprises two or more than two rectangular orifices equipped on the periphery surface of the mandrel body, a boring cutter block positioned in the rectangular orifices, and a boring cutter installed on the boring cutter block. The rolling portion comprises a ball track which is package installed on the periphery surface of the mandrel body on the right side of the boring cutter block with interference fit, a roller retainer which is package installed on the periphery surface of the ball track, and a roller which is roll equipped in the rectangular orifices of the roller retainer along the circumferential direction with uniform distribution, wherein a thrust bearing is package installed on the mandrel body on the right side of the roller retainer. The supporting portion comprises a cradle cover which is package installed on the mandrel body on the right side of the thrust bearing and an arc bakelite block which is equipped on the periphery surface of the mandrel body with uniform distribution. The utility model has the advantages of that the utility model can finish the cylinder-bore fine boring and rolling with one-pass operation by using the general deep-hole boring machine.

Description

Cylinder Inner Hole Bores And Rolls Device

Technical field

The utility model relates to the process equipment of cylinder barrel endoporus processing, especially relates to Cylinder Inner Hole Bores And Rolls Device.

Background technology

At present to cylinder barrel endoporus such as hydraulic prop, jack processing take 1 more, employing pushes away boring+honing technique, its weak point is that working (machining) efficiency is extremely low; 2, adopt and to push away boring+rolling technology, its weak point be push away boring, roll extrusion need be processed separately with two lathes, the equipment that takies is many, processing is long non-cutting time, and the resetting of workpiece need.Machining accuracy is difficult to guarantee the processing cost height; 3, adopt and to push away boring+scraping+roll extrusion combination process,, on common deep hole boring machine, can't use, and the use of equipment, maintenance cost are very high though the working (machining) efficiency height needs to be equipped with exigent special purpose machine tool.

The utility model content

The utility model purpose is to provide a kind of machining accuracy and efficient height, utilizes common deep hole boring machine once to finish the Cylinder Inner Hole Bores And Rolls Device of right boring and roll extrusion.

For achieving the above object, the utility model can be taked following technical proposals:

Cylinder Inner Hole Bores And Rolls Device described in the utility model, it comprises the mandrel body, is successively set on boring part, roll station, support section on the external side face of described mandrel from left to right; Described boring partly is opened in the two or more rectangular openings on the external side face of mandrel for symmetry and is arranged on the interior boring cutter piece of described rectangular opening, and is installed in the boring cutter on the described boring cutter piece; Described roll station is for being sleeved on the raceway on the external side face of boring cutter piece right side mandrel with interference fit, with the roller retainer that is sleeved on the described raceway outer peripheral face, and be arranged on roller in the described roller retainer rectangular opening along circumferential uniform rolling, on the mandrel body on roller retainer right side, be set with thrust bearing; Described support section is support cover for seat and the uniform arc bakelite piece that is arranged on its outer peripheral face that is sleeved on the mandrel body of described thrust bearing right side.

Described roller is divided into three segment sections vertically from left to right, and left part is segmented into the cone that has a1=2-4 degree tapering, and the pars intermedia segmentation is a cylinder, and right part is segmented into the cone that has a2=25-35 degree tapering.

Two rows about being arranged on roller in the described roller retainer rectangular opening and being along circumferential uniform rolling.

The utility model advantage is to utilize common deep hole boring machine can once finish right boring and roll extrusion to the cylinder barrel endoporus.During use, the boring cutter of mandrel body left end (front end) at first carries out turning processing to the cylinder barrel endoporus, by the roller in the roller retainer rectangular opening hole inwall is carried out roll extrusion then, reaches the design size requirement thereby make the hole inner wall surface produce certain plastic deformation; The support section effect is that boring hobboing cutter head is not sagging when guaranteeing to machine the back push broach, to avoid the sliding injury workpiece.If the boring cutter piece is set to two of symmetry, can by adjust boring cutter on it make in position radially two boring cutters cutter-aligndimension small one and large one, bear 1/2nd of boring surplus separately, therefore can strengthen the revolution amount of feeding, thereby circularity, the linearity of working (machining) efficiency and right boring processing have been improved, for rolling and processing provides suitable, uniform processing surplus.Two rows about roller is set to, advantage is that front-seat roller is mainly born the roll extrusion task, back row's roller rolls again reducing the resilience of metal surface, and reduces the metal surface roughness.Roller left part segmentation (leading portion) has reduced the roll extrusion resistance for having the cone of 2-4 degree tapering, and right part segmentation (back segment) has reduced the friction of roller and rolling surface for having the cone of 25-35 degree tapering.
