Automatic feeding device of spring grinding machine

Abstract

The invention relates to an automatic feeding device of a spring grinding machine. The automatic feeding device comprises a feeding platform, a linkage arm, a side swing arm, a movable feeding pipeline, a fixed feeding pipeline, a lifting seat, a first induction mechanism, a second induction mechanism, a lifting device and a first alarm mechanism, wherein the lifting device is arranged between thelifting seat and the feeding platform, and used for lifting the lifting seat upwards; a swing cavity penetrating through vertically is formed in the feeding platform; the linkage arm is used for linking the side swing arm with the lifting seat; the side swing arm horizontally swings in the swing cavity; a fixed feeding pipeline is arranged on the side swing arm; the two ends of the horizontal swing track of the side swing arm are respectively a first position and a second position; and when a spring to be processed is clamped between the tail end of the movable feeding pipeline and a clamp, the side swing arm is driven to swing to the second position, and the lifting seat is lifted by the lifting device to separate the spring to be processed from the clamp. By adopting the scheme, the automatic feeding device is high in feeding efficiency and capable of avoiding spring deformation and equipment damage.

Description

technical field [0001] The invention relates to the field of spring processing, in particular to an automatic feeding device for a spring grinding machine. Background technique [0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials are deformed under the action of external force, and return to their original shape after the external force is removed. Generally made of spring steel. The types of springs are complex and diverse, divided by shape, mainly cylindrical springs, scroll springs, leaf springs, special-shaped springs, etc. [0003] The spring grinding machine is a kind of equipment used to process the length of cylindrical springs. It usually includes a base, a turntable, a motor and a grinding device. The edge of the turntable is equidistantly provided with a plurality of fixtures for placing the springs to be processed, one of which is The position of the fixture corresponds to the grinding device, and the turntable r...

Problems solved by technology

[0004] Before the grinding device grinds the springs, the springs to be processed need to be placed in the fixtures. The traditional loading method is to manually place the springs in the fixtures. This loading method is inefficient and cannot be placed in time. The fixtures are all equipped with springs, which will reduce the efficiency. If you are tired and distracted during the placement process, it is easy to cause safety accidents

[0005] In order to solve the above problems, a vibrating plate is used instead of manual feeding. The discharge position of the vibrating plate is connected to one of the clamps through the transmission pipeline of the conveying spring, so as to realize the function of automatic feeding. However, this feeding method Although the problem of low placement efficiency is solved, there are still some disadvantages: ①The transmission pipe is a soft pipe, which is prone to a small amount of deformation, and this small amount of deformation will increase the amount of friction between the inner wall of the soft pipe and the outer circumference of the spring , which hinders the smooth feeding of the spring; ②The spring will be stuck at the end of the soft pipe in a small amount, causing half of it to be placed in the fixture, and the other end will remain in the soft pipe. As the turntable will continue to rotate, the spring will be in the soft pipe. The interaction between the pipe and the turntable continues to deform, resulting in deformed waste, and at the same time causing damage to the fixture and soft pipe, affecting the normal processing of the spring grinding machine
