Abstract
The utility model relates to a two roller inner hole fitting and rolling apparatus, which comprises a connecting rod, a rolling wheel, a mandril, a supporting rack, a spring, a small cylinder, a through hole, a key groove, a step, etc. The vertical through hole is arranged in the connecting rod in which the supporting rack connected with the mandrel and the small cylinder sheathed with the compression spring are arranged. The rolling wheel is arranged on the mandrel, and can be freely rotated, and the mandrel is arranged in the key groove, and can be moved up and down. The utility model can overcome the pit phenomenon and the peeling phenomenon occurring after the hole wall of the work piece is processed by the rigid rolling. The two roller inner hole fitting and rolling apparatus is especially suitable for inner hole fine machining on the large work pieces which are difficult to make the inner hole fine machining by utilizing the grinding technology and the boring technology.
Description
The utility model belongs to the manufacturing of the polishing rolling device in the machining.
In order to improve the crudy in metal works endoporus (especially larger-diameter hole), promptly reduce the surface roughness in hole, mainly adopt processes such as internal grinding, right boring.Because original internal rolling device all is the rigidity roll extrusion, promptly the axle base between two processing rollers must according to the size in workpiece aperture, by operator's manual setting, can't change in the process before rolling and processing begins.In addition, the rigidity roll extrusion can make the workpiece hole wall produce defectives such as " pit ", " peeling " after processing, causes workpiece quality to descend, thereby does not generally adopt rolling depression method to improve the crudy of endoporus.
The purpose of this utility model is to provide a kind of two-wheeled endoporus polishing rolling device, it has improved traditional internal rolling processing unit (plant), become the rigidity roll extrusion and be the elasticity roll extrusion, can overcome above-mentioned shortcoming, reduce the roughness of hole wall, promptly improve the surface smoothness of hole wall, thereby improve the crudy of workpiece, reach the requirement of design and use.
The utility model comprises that parts such as connecting rod, roller, axle, support, spring, nut, small cylinder, through hole, keyway and step constitute.
The utility model is described in detail as follows with reference to accompanying drawing:
Fig. 1 is a two-wheeled endoporus polishing rolling device generalized section.
As shown in the figure: the 1-connecting rod, the 2-roller, the 3-axle, the 4-support, 5-compresses spring, 6-nut, 7-small cylinder, 8-vertical through hole, 9-longitudinal hole, 10-keyway, 11-step, 12-axle rectangle end, 13-screw thread.
Connecting rod 1 is the ladder cylinder, and the head of connecting rod 1 (left end) is provided with a vertical through hole 8, and the afterbody (right-hand member) of the connecting rod 1 that is connected with machining tool has spiral shell mosquito 13, in a longitudinal hole 9 (alleviator weight) is arranged; Vertical through hole 8 is interior to compress spring 5 for two cylindrical shape supports 4 are installed up and down symmetrically, support 4 openings outwards and with the two ends of axle 3 are connected, the bottom of top support 4 is provided with small cylinder 7, and compression spring 5 is enclosed within on the small cylinder 7, in order to avoid radial-play; Roller 2 (2) is installed in axle 3 (2 s') centre, and axle 3 center-right sides have a step 11, is used for fixing an end face of roller 2, and axle 3 center-left sides are provided with nut 6, are used for fixing the other end of roller 2; Roller 2 can rotate on axle 3 freely; Offer the rectangle keyway 10 of symmetry on the hole wall of vertical through hole 8, the end, square-section 12 at the two ends on the axle 3 just in time is installed in the keyway 10 with mating, makes axle 3 can do suitable moving up and down in keyway 10.The material of roller of the present utility model adopts alloy tool steel 5CrMnMo or T10A usually, and quenching hardness is HRC52～55.
The utility model work the time be place it in by the hole of roll extrusion workpiece in, according to by the surplus size of hole rolling, but the size of automatic adjuster spring power, thereby make two rollers and tightly contacted, carry out the roll extrusion of hole face by the hole rolling hole wall.In the roll extrusion process, this rolling device rotates synchronously with the rotation of lathe main shaft, and two rollers also produce rotation, thereby has produced the elasticity rolling and processing to the workpiece hole wall.
The utility model can overcome " pit " and " peeling " phenomenon that workpiece hole wall processing back appears in the rigidity roll extrusion, processing work by roll extrusion after, the surface roughness in hole reduces by 2～3 grades, can reach Ra 1.6～0.40 (being that surface smoothness has improved 2～3 grades), improved simultaneously the wearability of workpiece significantly, fatigue resistance and service life, and can enhance productivity 50～60%, for being difficult to use grinding, boring technology is carried out the accurately machined heavy type of endoporus, large-scale workpiece, be more suitable for using this rolling device and carry out hole fine finishining, or polishing processing, therefore, can be widely used in mechanical processing industry.
