Description

Technical Field

[0001] This utility model relates to sprocket processing technology, specifically to a sprocket synchronous deburring device. Background Technology

[0002] Existing deburring machinery often mimics manual operation, using steel or bristle brush wheels mounted on a rotating mechanism with an electric handle, fixed in place by a frame. Some sections require pneumatic or hydraulic cylinders for precise control of the workstation details. This setup is widely used due to its intuitiveness and ease of understanding. However, it suffers from the drawback of requiring individual grinding of each tooth groove, unlike manual deburring where workers can visually adjust positions to improve efficiency. Mechanical production lines must adhere to a predetermined path, further extending the processing cycle for a single tooth groove. Furthermore, there is the hidden problem of incomplete grinding in a single pass. To address this, a brush grinding machine is typically installed for every two adjacent tooth grooves. If increased efficiency is desired, this approach only requires increasing the number of brush grinding machines and mirroring their configuration, resulting in a poor cost-benefit ratio. Therefore, a more efficient deburring device is needed for sprockets with fully chamfered teeth. Summary of the Invention

[0003] This invention addresses the issue that existing deburring devices typically mimic or are modified from manual operations, resulting in excessively long processing times for sprockets that have undergone chamfering before deburring. Therefore, a synchronous deburring device for sprockets is designed.

[0004] This utility model provides a sprocket synchronous deburring device, including: a deburring barrel structure, a sprocket propulsion structure and a feeding gripper mechanism; the feeding gripper mechanism is disposed between the deburring barrel structure and the sprocket propulsion structure, and the deburring barrel structure and the sprocket propulsion structure are coaxially arranged. The deburring barrel structure includes: a lower fixing ring, the lower fixing ring having a number of teeth matching the sprocket to be deburred and a diameter larger than the sprocket to be deburred; a tooth side cleaning plate and a tooth groove cleaning plate are provided on the lower fixing ring, the tooth side cleaning plate and the tooth groove cleaning plate are alternately arranged; an guide triangle plate is provided on the lower side of the lower fixing ring, the guide triangle plate is matched with the tooth groove cleaning plate in the setting position. The toothed cleaning plate is hinged to the lower fixing ring; The upper fixing ring is sleeved on the outside of the tooth side cleaning plate and the tooth groove cleaning plate, and is individually connected to the outside of each tooth side cleaning plate or tooth groove cleaning plate by a return spring. The sprocket propulsion structure includes a vertically arranged hydraulic telescopic cylinder, and a sprocket mounting platform is provided on the telescopic end of the hydraulic telescopic cylinder. The telescopic axis of the hydraulic telescopic cylinder is coaxial with the deburring barrel-shaped structure.

[0005] Preferably, the sprocket mounting platform includes a first frustum, a second cylinder, and a third cylinder; the three are coaxial and integrally formed; the bottom of the first frustum and the diameter of the second cylinder are both matched with the inner diameter of the sprocket that needs to be deburred; the diameter of the third cylinder is larger than the diameter of the second cylinder.

[0006] Preferably, the tooth side cleaning plate is rectangular in shape with a polished inner surface. The tooth side cleaning plate includes an upper section and a lower section, with the upper section being less than or equal to the lower section. The upper section has auxiliary plates folded on both the left and right sides, and the angle formed by the auxiliary plates and the main body of the tooth side cleaning plate matches the teeth of the sprocket. The tooth groove cleaning plate consists of three grinding plates: left, middle, and right. The included angle between the three grinding plates forms the tooth groove size of the sprocket that needs to be deburred. The upper section of the tooth side cleaning plate is located on a plane circle with the central axis of the deburring barrel structure as the center, outside the tooth groove cleaning plate.

[0007] The width of the left and right plates of the toothed cleaning plate decreases from bottom to top.

[0008] Preferably, the feeding gripper mechanism includes: a rotary cylinder with its rotating shaft vertically arranged, a gripper cylinder horizontally arranged on the rotating surface of the rotary cylinder, and a gripper arm connected to the gripper of the gripper cylinder; the adjacent surfaces of the gripper arm are provided with arc surfaces to match the outer diameter of the sprocket being gripped.

[0009] A second pneumatic telescopic cylinder is provided at the bottom of the rotary cylinder, and the telescopic axis of the telescopic cylinder passes through the rotating shaft of the rotary cylinder. A guide rod is provided at the top of the rotary cylinder; Preferably, a second rotary cylinder is provided between the gripper cylinder and the rotary cylinder of the feeding gripper mechanism; the rotation axis of the second rotary cylinder intersects the rotation axis of the rotary cylinder at 90°; the cylinder body of the second rotary cylinder is set on the top of the rotary cylinder by an L-shaped fixing block, and the cylinder body of the gripper cylinder is set on the center of the rotation surface of the second rotary cylinder, which overlaps with the rotation axis of the second rotary cylinder.

[0010] Preferably, the top of the deburred barrel structure is also provided with a feeding gripper mechanism, the structure of which is the same as that of the feeding gripper mechanism.

[0011] This invention employs multiple friction plates and a push rod to achieve deburring through compression converted into friction. Unlike rotary grinding, the grinding discs in this application use a long strip structure, thus eliminating the most expensive rotary motor component, saving costs and simplifying the placement of the grinding discs. This allows for convenient arrangement of the number of grinding discs based on the number of teeth on the sprocket, achieving simultaneous deburring. An example is a bottom-loading, vertically pushed upwards for processing, and top-loading scheme. During the triangular plate introduction stage, the sprocket's tooth grooves are finely adjusted to ensure each tooth groove aligns with the tooth groove cleaning plate, or in other words, the teeth align with the tooth side cleaning plate. As the sprocket pushing structure continues to push the sprocket upwards, each tooth side cleaning plate and tooth groove cleaning plate compresses the sprocket, generating sufficient friction during the upward movement to deburr and grind the sprocket.

[0012] If one pass is insufficient for polishing, a selective polishing method can be chosen where the sprocket returns to the loading point after flipping, allowing for a second polishing of the flipped sprocket. This polishing method still takes less time than traditional tooth-by-tooth polishing. Attached Figure Description
