Description

Technical Field

[0001] The utility model relates to the field of piston ring processing, in particular to a horizontal feeding device for an automatic piston ring trimming machine. Background Technique

[0002] In the existing automatic piston ring processing technology, especially in the grinding process of the piston ring by the trimming machine, which is the last processing process of the piston ring, it is particularly important to maintain the quality of the machined surface of the piston ring.

[0003] At present, most of the automatic feeding methods of piston rings are that the piston rings are horizontally placed and stacked into a stack, and the conveying of this method is that each piston ring is reciprocally pushed by a push plate below to the processing station; or the piston rings are vertically stacked in a V-shaped groove, and the vertical push plate pushes one piston ring to the processing station each time. When pushing, one end face of the piston ring slides against the slide plate of the machine tool. This forced feeding method of the piston ring is likely to cause defects such as bumps, scratches, etc. on the machined surface, affecting the appearance of the workpiece, and even scrapping the workpiece in severe cases.

[0004] Moreover, when the piston rings are vertically stacked in a V-shaped groove and pushed, the piston rings are squeezed, and it often occurs that it is difficult to push. Therefore, the working efficiency is not high.

[0005] Therefore, a horizontal feeding device for an automatic piston ring trimming machine is needed, which can realize automatic feeding during the processing process, avoid defects such as bumps, scratches, breakage, etc. during the feeding and conveying process, reduce the labor intensity of the operator, ensure the smooth transfer of the piston rings, and improve the working efficiency.

[0008] A horizontal feeding device for an automatic piston ring trimming machine includes a base, and a ring pushing device, a hanging rod, and a clamping and moving device are arranged above the base. Among them, the ring pushing device is located on the left side of the hanging rod, and the clamping and moving device is located on the front side of the hanging rod. The cross-section of the hanging rod is in an inverted T shape, and includes a hanging part, an inclined part, and a part to be clamped. Arc-shaped bosses are arranged on both sides of the connection point position between the hanging part and the inclined part.

[0009] There are two ring pushing devices, and each ring pushing device includes a cylinder. The cylinder is fixed on the base through a connecting column, and the output end of the cylinder is fixed to a pusher.

[0010] The clamping and moving device includes a laterally arranged side plate, which is fixed on the base through support columns.

A first slider that is adapted and slidable is arranged in the horizontal chute. The first slider is threadedly connected to the horizontal lead screw. One side of the first slider away from the horizontal chute is fixedly connected to a vertical side plate. On one side of the vertical side plate opposite to the hanging rod, there is a vertical chute. A vertical lead screw is arranged in the vertical chute. The bottom end of the vertical lead screw is connected to the inner wall of the vertical chute by a bearing, and the upper end is connected to the output end of a second motor outside the vertical side plate through a coupling. A second slider that is adapted and slidable is arranged in the vertical chute. The second slider is threadedly connected to the vertical lead screw.

[0019] By using an arc-shaped stepped pusher and jaws provided with rubber pads, it is ensured that the machined surface of the piston ring is effectively protected during the pushing and clamping processes, avoiding quality problems such as scratches and bumps, and significantly improving the product qualification rate.

[0020] Through the close cooperation of batch feeding, automatic pushing, and precise clamping, the efficient and automated feeding of piston rings is achieved. The piston rings can be quickly moved to the processing procedures of the piston ring trimming machine equipment, greatly improving production efficiency, reducing manual intervention, and lowering the labor intensity of operators.

One end of the lateral lead screw 11 is connected to the inner wall of the lateral sliding groove 10 by a bearing, and the other end is connected to the output end of the first motor 12 outside the side plate 9 through a coupling. Inside the lateral sliding groove 10, there is a first slider 13 that is adapted and slidable. The first slider 13 is threadedly connected to the lateral lead screw 11. The side of the first slider 13 away from the lateral sliding groove 10 is fixedly connected to a vertical side plate 14. On one side of the vertical side plate 14 opposite to the hanging rod 2, there is a vertical sliding groove 15. Inside the vertical sliding groove 15, there is a vertical lead screw 16. The bottom end of the vertical lead screw 16 is connected to the inner wall of the vertical sliding groove 15 by a bearing, and the upper end is connected to the output end of the second motor 17 outside the vertical side plate 14 through a coupling. Inside the vertical sliding groove 15, there is a second slider 18 that is adapted and slidable. The second slider 18 is threadedly connected to the vertical lead screw 16. The side of the second slider 18 away from the vertical sliding groove 15 is fixedly connected to a rotary cylinder 19. A ring-taking device is provided on the rotary cylinder 19.

[0030] The ring-taking device includes an opening and closing cylinder 20 fixed on the output end of the rotary cylinder 19 and a claw 22 provided on the output end of the opening and closing cylinder for clamping the piston ring 21. The claw 22 is provided in two parts that can move relative to each other along the opening and closing cylinder 20.

[0031] The hanging part 3 of the hanging rod 2 is used for batch mounting of the piston rings 21.

[0032] The pusher 8 is in an arc-shaped stepped shape, and the two pushers 8 are adapted to the outer side surfaces and the outer circumferential surfaces on both sides of the piston ring 21.
