Description

Technical Field

[0001] The present invention relates to the field of machining technology, and in particular to a conveying device and a method for segmenting circular rings with multiple diameters. Background Art

[0002] In some feed machinery and equipment, fan-shaped block connectors are used in some mechanisms. The technical requirements are that a circular ring is divided into several sections, and the diameter of the circular ring has various specifications. In the circular ring segmentation technology, wire cutting or sawing is mostly used. Both segmentation methods require auxiliary tooling to transport the circular ring.

[0003] There are two supporting methods for existing ring conveying devices: one is flat plate support; the other is roller support. Flat plate support can adapt to rings of various diameters, but it is laborious to rotate the ring after cutting and it is easy to grind the end surface of the ring, which is not suitable for parts with high processing requirements; roller support saves effort when rotating the ring, but because the position of the roller is fixed, it can only adapt to rings with less diameter changes. Summary of the invention

[0004] The object of the present invention is to provide a conveying device and a ring segmentation method that can adapt to the segmentation of multi-diameter rings. All rollers of the conveying device point to the same center of a circle. By adjusting the center position of the rollers, the rollers can support rings of different diameters to always rotate on their respective centers of the circle, thereby meeting the segmentation requirements of rings of different sizes, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0007] A further solution of the present invention is that the bracket is a frame structure as a whole, the bottom end of the bracket is connected to a foot cup, and one end of the bracket at the bottom of the notch is an open structure without a cross bar; a transition support plate is connected between the ends of the outer ring support plate and the inner ring support plate, and the transition support plate connects the outer ring support plate and the inner ring support plate to form an integral structure.

[0008] A further solution of the present invention is that the fixed roller includes a roller A and a roller shaft A; the roller A is rotatably connected to the outer wall of the roller shaft A through a bearing, and U-shaped brackets are connected to the outer ring support plate and the inner ring support plate, and both ends of the roller shaft A are placed on the brackets.

[0009] A further solution of the present invention is that the self-aligning rollers are symmetrically arranged on both sides of the fixed roller; the self-aligning rollers include a roller B and a roller shaft B, and the roller B is rotatably connected to the outer wall of the roller shaft B through a bearing; a turntable is connected to the workbench on the outer side of the outer ring support plate, a slot is provided at the top of the turntable, one end of the roller shaft B is connected to a rotating block, the bottom end of the rotating block is connected to an insertion rod, the insertion rod is gap-fitted in the slot, and the other end of the roller shaft B is connected to an L-shaped shaft frame.

[0010] A further solution of the present invention is that there are four centering rollers, two of which are located on each side of the fixed roller, and the distances between adjacent centering rollers and between adjacent centering rollers and the fixed roller are the same.

[0011] A further solution of the present invention is that the self-aligning mechanism includes a rotating shaft, two bearing seats are connected to the bottom end of the bracket, the rotating shaft is rotatably connected to the bearing seats, one end of the rotating shaft extends to the outside of the workbench and is connected to a handwheel; two L-shaped plates are connected to the bottom end of the workbench, and a support plate is connected between the L-shaped plates; one end of the rotating shaft is connected to a lead screw, both ends of the lead screw are rotatably connected between the bracket and the support plate, and the nut block is threadedly engaged with the lead screw; a sliding rod is connected between the support plate and the bracket, and both ends of the nut block are slidably connected to the sliding rod; the top end of the nut block is connected to a self-aligning shaft, and the shaft frame is rotatably connected to the self-aligning shaft.

[0017] S3. Cutting: The two clamps of the clamp clamp the ring, and the saw blade of the horizontal band saw works and moves downward to complete the cutting of the ring; after one cutting, the clamp is released, and the ring is rotated according to the required size. After cutting again, the required fan-shaped block connector can be obtained, and this cycle is repeated.

[0018] S4. Self-aligning: When cutting rings of different diameters, turn the hand wheel, the screw rotates to drive the nut block to move forward or reverse, and the self-aligning shaft pulls the roller shaft B to rotate along the hinge point at the outer end, thereby adjusting the center of the self-aligning roller, so that the rings of different diameters always rotate on their respective centers.
