Problems solved by technology

The deficiency of this patent is obvious: it only has a single rolling function, but does not have the technical feature of turning function
It can be seen that in order to obtain the ideal conical surface effect, it is necessary to add a process, which obviously does not meet the energy-saving and efficient production standards.

Embodiment Construction

[0016] The present invention will be described in detail below in conjunction with the embodiments and drawings, but is not limited thereto.

[0017] A turning and rolling combination device for processing taper holes, comprising a tool bar 8, a hard alloy knife 7 and a support sleeve 2, the front end of the tool bar 8 is fixedly provided with bolts, and the support sleeve 2 is set on the bolts through a nut 1 It is fixedly connected with the knife bar 8, and the front half of the support sleeve 2 is provided with an upward adjustment knife hole 11 and a downward adjustment knife hole 12. The lower part of the lower adjustment knife hole 12 is inclined away from the knife bar 8. The lower adjustment knife hole 12 is coaxially aligned; the hard alloy knife 7 is set through the upper adjustment knife hole 11 and the lower adjustment knife hole 12, and the hard alloy knife handle is fixed by the fine adjustment screw 3, and the fine adjustment screw 3 is connected with the upper a...

Abstract

The invention relates to a combined turning rolling device used for processing a taper hole, wherein, two mechanically processing procedures are combined reasonably, so that the turning technology and the rolling technology can be achieved in the processing procedures during one cutting feed process, the matching quality can be improved, and processing cost is lowered; in addition, the surface roughness of an inner wall of the taper hole can be reduced to one to two stages by adopting the rolling technology, and the rigidity and the fatigue strength of an inner surface of the taper hole can be improved.

Description

technical field [0001] The invention relates to a turning and rolling combination device for processing taper holes, which belongs to the technical field of taper hole processing tools. Background technique [0002] The tapered holes processed by the current tapered hole processing technology are prone to technical defects such as excessive surface roughness and poor dimensional consistency. In order to reduce the surface roughness of the taper hole, the subsequent process often uses a grinder to grind the taper hole. Adding this process not only prolongs the construction period but also increases the production cost. [0003] Chinese patent CN201632807U discloses a tapered hole rolling tool, which is characterized in that rollers are arranged on the tapered surface of the rolling head, the rolling surface of the roller protrudes from the tapered surface of the rolling head, and the tapered hole is squeezed through the rolling surface The inner wall is rolled to improve the...
