Abstract
The invention discloses a cloud type lock spring winding tool. The invention solves the problem that the spring winding machine cannot process cloud-shaped lock springs through the cooperation of the winding die and multiple stations, overcomes the problems of poor product consistency, poor surface precision and low quality in manual processing, and provides the efficient and high-quality cloud-shaped lock spring winding die and method based on the multi-station numerical control spring winding machine.
Description
Technical Field
The invention belongs to the field of aviation machinery, and relates to a cloud-type lock spring winding tool.
Background
The cloud type lock spring is an aviation standard part with the standard number of HB2-54, is commonly used for fixing parts such as an aircraft interior trim panel, an electric appliance box cover and the like, and is very large in dosage. The structure of this part is two reverse spiral tower-shaped springs, and is less because of the complicated winding ratio of shape, and general class spring equipment can't process. At present, with the rapid development of the machine tool industry, a multi-station numerical control spring coiling machine appears, most of conventional springs are machined through the cooperative operation of all stations, but cloud type lock springs cannot be machined at present. At present, the manual forming method is adopted in the industry to process the part. However, the manual processing method has low efficiency, poor consistency of parts, easy scratch of the surfaces of the parts in the processing process and poor surface quality.
Disclosure of Invention
The purpose of the invention is: the invention solves the problem that a spring coiling machine cannot process a cloud-shaped lock spring, overcomes the problem in manual processing, and provides a cloud-shaped lock spring coiling tool.
The technical scheme of the invention is as follows: the cloud type lock spring winding tool comprises a guide plate, an upper die, a pressure spring (2), a lower die, a positioning boss 4, a winding round table, an upper die hollow shaft and a winding shaft;
the upper die hollow shaft and the winding shaft are arranged on the lower end face of the upper die; the winding shaft is rotatably arranged on the lower end face of the upper die; the lower end of the winding shaft is provided with a through groove vertical to the winding shaft;
the upper end surface of the lower die is provided with a guide plate, a pressure spring, a positioning boss and a winding round table; a spiral guide groove is formed in the cylindrical surface of the winding round table, and a protruding mandrel is formed on the upper end surface of the winding round table; when the spring is wound, the positioning boss is positioned on one side of the spring wire, and the winding round platform is positioned on the other side of the spring wire;
the lower end face of the upper die is opposite to the lower end face of the upper die, the upper die hollow shaft is sleeved on the mandrel for winding the circular truncated cone, and the upper die is rotationally arranged by taking the upper die hollow shaft as the center of a circle; when the upper die rotates, the winding shaft revolves around the winding round table, and the upper die can move upwards relative to the winding round table along the rotation axis while rotating
The guide plate is used for guiding and positioning the spring rod for winding the spring, and the pressure spring is used for pressing the spring rod on the upper end face of the lower die.
Furthermore, a mandrel or a clamping part is formed on the upper end surface of the positioning boss and used for positioning the wound spring.
Furthermore, the positioning boss and the winding round platform are inserted on the lower die and fixed with the lower die into a whole.
Further, in the axial direction of the rotation, the position of the through groove of the winding shaft is not higher than the spiral guide groove.
Further, the upper die is driven by a motor.
The using process is as follows:
1) the spring wire penetrates through the pressure spring and the guide plate, the positioning boss is located on one side of the spring wire, the winding round platform is located on the other side of the spring rod, the motor drives the upper die or the lower die to rotate, the through groove in the winding shaft drives the spring wire to rotate, and meanwhile, the upper die is driven by the motor to rotate and simultaneously ascend, so that the spring wire is upwards wound along the spiral groove of the winding round platform, and one end of the cloud-shaped spring is machined;
2) the spring wire is replaced, so that the unprocessed end is positioned between the winding round platform and the positioning boss, the upper die is driven by the motor to rotate and rise simultaneously, the spring wire is wound upwards along the spiral groove of the winding round platform, and the processing of the other end of the cloud-shaped spring is completed;
the invention has the advantages of
The spring winding machine solves the problem that a spring winding machine cannot process cloud-shaped lock springs through the cooperation of the winding die and multiple stations, and solves the problems of poor product consistency, poor surface precision and low quality in manual processing.
