Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of processing feeding device, in particular to a one-way star wheel feeding device. BACKGROUND

[0002] With the rapid development of the automotive field, the star wheel as a key part of the gearbox system, its production technology and assembly process level, affect the development and progress of the entire gearbox field, then the general star wheel processing technology is: blanking--forging into gear blank--normalizing--rough turning outer circle and hole and end face (according to standard to leave processing allowance)--quenching and high temperature tempering--finely turning outer circle and hole and end face (to the finished size)--tooth making (tooth surface leaves grinding allowance)--induction heating of tooth part and surface quenching or carburizing quenching--tooth surface grinding--acceptance and delivery, the star wheel as an important part of the automobile gearbox, the quality of the star wheel directly affects the noise, stability and service life of the automobile, so the star wheel needs to achieve the dual goals of quality and noise, and realize high efficiency production.

[0003] In the workpiece processing process in the traditional manufacturing industry, the workpiece needs to be placed on the clamping tool of the processing equipment by artificial (i.e. feeding), and after the processing is completed, it also needs to be taken down from the clamping tool by artificial (i.e. discharging), so that the repeated operation realizes the processing of the workpiece. The speed of feeding and discharging is slow in this operation mode, which will affect the processing efficiency. There is also a mechanical hand for feeding to the clamping tool, but due to the different diameters of the two sections of the star wheel, if it is sent to the position of the mechanical hand by the conveyor belt, the star wheel will fall down in the conveying process if the small diameter end of the star wheel is on the conveyor belt, so that the mechanical hand cannot be clamped in place. Therefore, in order to ensure that the star wheel does not fall down during the conveying process of the conveyor belt, it is necessary to keep the large diameter end of each star wheel in contact with the transmission belt, that is, the large diameter end is at the bottom and the small diameter end is at the top. This method is only suitable for one-end clamping processing, and the other-end clamping processing (such as clamping the small end and processing the large end) needs to rely on a turnover mechanism, which causes more parts and control, resulting in increased cost. SUMMARY

[0004] In view of the deficiencies of the prior art, the one-way star wheel feeding device can orderly convey disordered workpieces and correct the positions of the workpieces, avoid the falling of the star wheel, and facilitate the subsequent clamping operation of the star wheel.

[0005] To achieve the purpose of orderly conveying disordered workpieces at a certain speed and correcting the positions of the workpieces, the present application provides the following technical scheme: a one-way star wheel feeding device, a support, the support is vertically installed on the top of the base;

[0006] A tray is rotatably mounted on a support, a top surface of the tray is provided with a plurality of accommodating holes for carrying a star wheel, and the accommodating holes are stepped holes with a large upper part and a small lower part;

[0007] A driver is mounted inside the base, and a rotation driven part for driving the tray to rotate around the support is arranged between the power output end of the driver and the tray.

[0008] Compared with the prior art, the one-way device star wheel feeding device has the following beneficial effects:

[0009] 1. The one-way device star wheel feeding device, by cooperation of the base, the tray and the rotation driven part, the base is installed below the discharge port, the workpiece falls into the accommodating hole on the tray through the pipeline, the driver is started, the rotation driven part is driven to rotate under the action of the driver, the tray is driven to rotate, the star wheel is clamped and sent out by the mechanical claw when the tray rotates to the specified position, so that the unordered workpiece is orderly transported at a certain speed.

[0010] 2. The workpiece enters the accommodating hole of the tray, and since the accommodating hole is a stepped hole with a large upper part and a small lower part, when the large end of the star wheel needs to be clamped and sent out by the mechanical claw, the small end of the star wheel is located in the small hole of the stepped hole, the large end of the star wheel is supported by the bottom of the large stepped hole, so that the large end of the star wheel is exposed from the tray, and the mechanical claw can clamp, when the small end of the star wheel needs to be clamped and sent out by the mechanical claw, the large end of the star wheel is supported by the bottom of the large stepped hole, so that the small end of the star wheel is completely exposed from the tray, and the mechanical claw can clamp. The size of the star wheel is adapted and limited by the stepped hole, so that the star wheel does not fall during transportation, and the subsequent clamping operation of the star wheel is facilitated.

[0011] Further, the top of the support sleeve is fixedly installed with an extension rod, one side of the extension rod is fixedly installed with a support rod, and the bottom of the support rod is movably installed with a baffle.

[0012] If the star wheel does not enter the accommodating hole smoothly due to special circumstances, part of the star wheel stays on the top outer surface of the tray, the star wheel contacts the baffle during rotation of the tray, the baffle pushes the star wheel, so that the star wheel enters the accommodating hole of the tray or falls off the tray, and the production process is not interrupted due to accumulation of the star wheel, so that the position of the star wheel is corrected. The height position of the baffle is adjusted by adjusting the top support sleeve to adjust the height of the extension rod, so that the baffle of the support rod can pass the star wheel normally located in the accommodating hole of the tray.
