Description

Technical Field

[0001] The utility model relates to the technical field of automatic assembly equipment, in particular to a spring blanking rotating device. Background Art

[0002] At present, in the automatic assembly process of automobile parts, a spring automatic assembly device is usually used to automatically assemble the spring into the hole of the part, thereby improving work efficiency while preventing processing defects such as wrong assembly and missing assembly. The spring automatic assembly device is already in the public state as a prior art.

[0003] The authorized patent with announcement number CN216326276U proposes "a spring automatic assembly blanking device, including a spring automatic feeding mechanism; the bottom of the spring automatic feeding mechanism is fixedly connected to a fixed base plate; the bottom left side of the spring automatic feeding mechanism is also fixedly connected to a feeding pipe; a blanking pipe is embedded and installed on the inner side of the bottom of the feeding pipe; a pipe clamp is fixedly installed on the outside of the blanking pipe by bolts; a connecting block is fixedly connected to the top right of the pipe clamp; a cylinder is fixedly installed on the lower right side of the fixed base plate through a connecting frame; the top of the cylinder is fixedly connected to the bottom of the connecting block". After implementation, "the feeding pipe in the utility model is used to feed the spring to The feeding tube is transported downward, and a drop tube that can slide up and down is also arranged on the inner side of the bottom of the feeding tube. When assembling the spring, the bottom of the drop tube can directly and closely contact the part hole, which can make the drop more stable. Moreover, when sliding up and down, the arc plate above the drop tube and the arc plate below the inner tube of the feeding tube can always ensure that their inner sides are connected with each other in the horizontal direction. That is to say, the inner wall is always smooth and vertical from top to bottom. Compared with the current spring assembly device, this device can limit and guide the spring through the cooperation of the feeding tube and the drop tube when the spring falls, and the drop tube is accurately sent to the assembly position through the cylinder. Therefore, the spring will not tilt after falling, and the fall is stable, without the need for later correction, and the assembly efficiency is greatly improved.

[0004] It can be seen from the above technical content that in order to avoid displacement and jamming of the spring assembly, the prior art adopts a blanking tube that can reciprocate and extend to penetrate into the installation hole to further expand the smooth flow channel. However, in the actual processing process, the distance margin between some processing holes and the spring is not much, and there is no space for the blanking tube to be assembled. It can be seen that the above prior art still has limitations in practicality. Utility Model Content

One end of the active discharging component passes through the extension tube and is connected to the electric push rod for transmission. The other end of the active discharging component can move toward the bottom port of the blanking pipe along the flow channel composed of the transition pipe and the blanking pipe under the transmission of the electric push rod.

[0009] Preferably, a sealing ring is provided at the fitting position between the bottom of the transition pipe and the top of the blanking pipe, and the central axis of the transition pipe coincides with the central axis of the blanking pipe.

[0010] Preferably, the meshing transmission component includes a second gear and a servo motor, the output end of the servo motor is transmission-connected to the top of the second gear, and one side of the second gear is meshingly transmitted with one side of the first gear.

[0011] Preferably, a weight-reducing groove is provided inside the second gear and inside the first gear, and the center of the first gear coincides with the central axis of the blanking tube.

[0012] Preferably, the top of the support sleeve and the bottom structure of the first gear are mounted with screws.

The utility model forms a blanking rotation mechanism through the provision of a transition tube, a blanking tube, a first gear, a second gear, and a servo motor, and forms an automatic limiting mechanism through the provision of a support sleeve, a limiting crank rod, an electromagnetic suction cup, and a magnet block. After the above two mechanisms are used together with a frame, in addition to meeting the blanking transfer requirements, before blanking, the servo motor drives the blanking tube and the spring inside the blanking tube to rotate synchronously through the second gear and the first gear, thereby utilizing the centrifugal effect of rotation to make the spring stay in a vertical state inside the blanking tube, thereby reducing the probability of poor processing of the spring during the blanking process.
