Description

Technical Field

[0001] This utility model relates to a feeding device, specifically to a press-fit feeding machine for an oxygen sensor dust cover retaining ring assembly. Background Technology

[0002] To prevent dust accumulation, an oxygen sensor requires a dust cover at its inlet. To secure the dust cover, a retaining ring is pressed into the sensor's housing. The edge of the retaining ring deforms at a locking point, creating an interference fit with the housing to stabilize the dust cover. Because oxygen sensors are relatively small, gripping them with robotic arms or chucks is difficult. While vacuum suction is used for "clamping," this method is inefficient and prone to workpiece misalignment during loading. Utility Model Content

[0003] The present invention aims to provide a press-fit feeding machine for oxygen sensor dust cover retaining ring assembly with good feeding stability and high efficiency.

[0004] The oxygen sensor dust cover retaining ring assembly press-fitting and feeding machine in this solution includes a base frame with a support platform on the base frame; a lifting column is vertically and slidably mounted on the support platform, and a clamping device is provided on the lifting column; a feeding turntable mechanism includes a turntable and multiple kit devices, the turntable is horizontally rotatable on the platform of the support platform, and multiple kit devices are arranged circumferentially on the turntable, with the multiple kit devices evenly distributed on the turntable; the kit devices can overlap to fit multiple workpieces; a workpiece conveying device is located on the support platform on one side of the turntable, and the conveying device is equipped with a vacuum suction head; a through hole is opened in the center of the feeding turntable, and the lifting column passes through the through hole and is mounted on the support platform, with a sliding fit or a gap between the lifting column and the through hole.

[0005] Furthermore, the kit includes a fixed base, a sleeve rod, and a sleeve support. The fixed base is fixedly mounted on the turntable. The sleeve rod is vertically arranged and its bottom is fixedly mounted on the fixed base. The sleeve support is fitted onto the sleeve rod and falls to the bottom. The workpiece is overlapped on the body of the sleeve rod above the sleeve support.

[0006] Furthermore, the fixing base includes a base body, a connecting plate, a pressure cap, and a pressing handle. The base body and the connecting plate are L-shaped. The free end of the connecting plate is horizontally arranged and fixedly connected to the circumferential edge of the turntable by screws. The other end of the connecting plate is integrally formed into the base body. The base body is vertically arranged and has a slot. The bottom of the sleeve rod is inserted into the slot. The pressure cap is rotatably disposed at one end of the base body, and the pressing handle is disposed on the pressure cap.

[0007] Furthermore, the clamping device includes a fixed frame, a driver, and a three-jaw gripper. One end of the fixed frame is fixedly mounted on the top of the lifting column, and the other end of the fixed frame is fixedly mounted on the driver.

[0009] Furthermore, the end of the vacuum adsorption head is provided with a ring of adsorption holes.

[0010] The advantages of this invention are as follows: Due to the hollow annular shape and small size of the retaining ring of the workpiece to be assembled, the oxygen sensor dust cover retaining ring assembly press-fitting and feeding machine designed in this scheme adopts a dual method of sleeve rod positioning and vacuum adsorption, which can ensure the stability and positional accuracy of the workpiece feeding, making it less prone to displacement. Furthermore, the use of a turntable and overlapping nesting method for workpiece transfer and feeding improves production efficiency. Attached Figure Description

A clamping device 400 is provided on the lifting column 300 for pushing and feeding components.

[0022] See details Figure 1 and Figure 2 The feeding turntable mechanism 600 includes a turntable 601 and multiple kit devices. The turntable 601 is provided with kit devices at intervals around its circumferential edge, and the multiple kit devices are evenly distributed on the turntable 601.

The sleeve rod 603 is vertically oriented, with its bottom fixed to the fixed base 602. The sleeve support 604 is fitted onto the sleeve rod 603 and falls to the bottom. Workpieces are overlapped on the body of the sleeve rod 603 above the sleeve support 604. The clamping device 400 clamps the sleeve support 604, and as the lifting column 300 rises, the sleeve support 604 pushes the workpieces fitted on the sleeve rod 603 one by one to the top of the sleeve rod 603, where they are sucked up by the vacuum suction head 401 (described later) and transported to the pressing process via the track (described later).

[0024] The turntable 601 is horizontally rotatable on the platform 200. The turntable 601 is driven by a motor (not shown in the figure) located under the platform 200. A through hole is provided at the center of the feeding turntable 601. The lifting column 300 passes through the through hole and is mounted on the platform 200.
