Automatic interior-angle chamfering machine

Abstract

The invention provides an automatic interior-angle chamfering machine, relates to mechanical processing equipment, and in particular relates to a device for carrying out interior-angle chamfering on piston rings. The automatic interior-angle chamfering machine comprises a machine frame, a panel is arranged above the machine frame, a feeding device and a swaging device are arranged on the panel, a mould mounting opening is arranged on the panel, and a mould is arranged in the mould mounting opening. A hollow spindle is connected below the mold, the hollow spindle is connected with a spindle mounting seat through an upper cone roller bearing and a lower cone roller bearing, and the spindle mounting seat is connected with the panel. An upper bearing pressing cover is arranged above the upper cone roller bearing, and a lower bearing pressing cover is arranged under the lower cone roller bearing. The hollow spindle under the spindle mounting seat is connected with a spindle belt pulley, the spindle belt pulley is connected with a power device, and the hollow spindle under the spindle belt pulley is in threaded connection with a round nut. Cutter frame shafts penetrate through the hollow spindle at intervals, the upper ends of the cutter frame shafts are connected with a cutter frame, the cutter frame is connected with a cutter, and the cutter is arranged in the mould. The lower end of the cutter frame shaft is connected with a stepping motor through a connecting piece. The automatic interior-angle chamfering machine is high in efficiency and low in cost.

Description

technical field [0001] The invention relates to machining equipment, in particular to a device for chamfering inner corners of piston rings. Background technique [0002] The piston ring is a non-circular metal ring with an opening, and a metal elastic ring with a large outward expansion deformation, which is assembled into the cross-section and its corresponding annular groove. After the piston ring is finished, it must be chamfered inside the piston ring. The existing processing method is: the operator holds the piston ring to be processed, presses it into the ring grinding, turns on the pedal, rotates the main shaft, feeds the tool with the carriage, and takes out the processed ring after completion. This method depends entirely on the operation. The experience of the workers, the technology is backward, the randomness is large, the quality cannot be guaranteed, the labor intensity is high, and the work efficiency is low. There are also imported equipment, but the cost ...

Problems solved by technology

The existing processing method is: the operator holds the piston ring to be processed, presses it into the ring grinding, turns on the pedal, rotates the main shaft, feeds the tool with the carriage, and takes out the processed ring after completion. This method depends entirely on the operation. Inexperienced workers, outdated technology, large randomness, unguaranteed quality, high labor intensity, and low work efficiency

In addition, there are imported equipment, but the cost is high
