Description

Technical Field

[0001] This utility model belongs to the technical field of deburring devices, specifically a deburring device for metal chains with irregular cross-sections. Background Technology

[0002] Chemical deburring devices for irregularly shaped metal chains often utilize electrochemical principles, such as electrolytic deburring equipment. This involves fixing the tool cathode near the burr-covered area of ​​the workpiece, connecting the workpiece to the positive terminal of a DC power supply, and connecting the tool cathode to the negative terminal. Under the action of an electrolyte, the burrs undergo anodic dissolution and are removed. This device is widely used in pneumatic, hydraulic, engineering machinery, fuel injectors and pumps, automotive, and engine industries for deburring pump bodies, valve bodies, connecting rods, plunger needle valve assemblies, and other parts made of different metals. It is particularly suitable for removing burrs from hidden areas such as intersecting holes or complex-shaped parts. It boasts high production efficiency, with deburring time typically ranging from a few seconds to tens of seconds, meeting the demands of high-precision machining. However, when using existing chemical deburring devices, the chain tends to clump together inside the device after the operator puts it in, preventing the chain from fully contacting the chemical liquid phase. This results in incomplete deburring and poor performance. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a metal chain deburring device with an irregular cross section, which effectively solves the problem that when the operator puts the chain into the device, it will pile up into a clump, which prevents the chain from fully contacting the chemical liquid phase and thus causes the burrs to be not completely removed.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a metal chain deburring device with an irregular cross-section, comprising a reaction cylinder, four support feet fixedly and equidistantly installed at the bottom of the reaction cylinder, a discharge valve fixedly installed at the middle of the bottom of the reaction cylinder, a top plate fixedly installed on the surface of the reaction cylinder by three support rods, an electric push rod fixedly installed on the upper part of the top plate, the transmission end of the electric push rod penetrating downward through the top plate and fixedly installed with a mounting base, a servo motor fixedly installed at the bottom of the mounting base, a shaft fixedly installed at the output end of the servo motor, the bottom end of the shaft extending into the interior of the reaction cylinder and fixedly installed with a support arm, an inclined surface opened on the upper part of the inner wall of the reaction cylinder, four placement slots opened parallel and equidistantly on the upper part of the support arm, and a positioning component for positioning the metal chain provided inside the support arm.

[0005] Preferably, a bushing is rotatably mounted on the upper end of the shaft surface, and two slide rods are symmetrically fixedly mounted on the surface of the bushing, with both slide rods movably inserted into both sides of the top plate.

[0006] Preferably, the positioning component includes two connecting seats, each with a ball bearing rotatably mounted on its opposite side, and a first rectangular rod fixedly mounted on its opposite side. A first connecting plate is fixedly mounted on the opposite end of each of the two first rectangular rods, and a connecting rod is fixedly mounted on the lower part of each of the two first connecting plates. A second connecting plate is fixedly mounted on the opposite end of each of the two connecting rods, and a second rectangular rod is fixedly mounted on the opposite side of each of the two second connecting plates. Insert rods are fixedly mounted on the opposite sides of both the two second connecting plates and the two first connecting plates.

[0007] Preferably, a first pressure plate is fixedly installed at one end of each of the two first rectangular rods, a first spring is sleeved in the middle of each of the two first rectangular rods, a second pressure plate is fixedly installed at the opposite ends of each of the two second rectangular rods, a second spring is sleeved in the middle of each of the two second rectangular rods, and a rectangular sleeve is sleeved at the other end of each of the two first and two second rectangular rods. The tops of the four rectangular sleeves are fixedly connected to the inner top of the support arm, and the two ends of the two first springs are fixedly connected to the rectangular sleeves and the first pressure plate, respectively. The two ends of the two second springs are fixedly connected to the rectangular sleeves and the second pressure plate, respectively.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the operator places the chain links located in the middle of the four irregular cross-section metal chains on the placement slots of the four support arms, so that the two ends of the four irregular cross-section metal chains hang down and extend naturally; then, the electric push rod is activated to drive the mounting base and servo motor to move down. When the servo motor moves down, it drives the support arms into the interior of the reaction cylinder through the shaft, thereby driving the four irregular cross-section metal chains into the chemical solution of the reaction cylinder for reaction. At the same time as the shaft moves down, it also drives the two sliding rods to move down through the bushing, ensuring the stability of the shaft when it moves down. During the downward movement of the support arm, the inclined plane guides and pushes the two connecting seats to move towards each other smoothly through the two ball bearings. When the two connecting seats move towards each other, the two first rectangular rods drive the two first connecting discs to move towards each other. When the two first connecting discs move towards each other, they drive the two second connecting discs to move towards each other through the connecting rods. When the two second connecting discs move towards each other, they drive the two second rectangular rods to move. When the two second rectangular rods and the two first rectangular rods move towards each other, they slide along the inside of the rectangular sleeve and squeeze the first spring and the second spring through the two first pressure plates and the two second pressure plates. This ensures the stability of the movement of the two second rectangular rods and the two first rectangular rods while giving them the ability to elastically reset. When the two first connecting discs and the two second connecting discs move, they drive the insertion rod to insert into the middle of the chain link in the placement slot, thereby quickly positioning the irregular cross-section metal chain. Next, the servo motor is started to drive the shaft to rotate slowly. As the shaft rotates, it rotates along the inside of the bushing, ensuring the stability of the shaft rotation. When the shaft rotates, it drives the four irregularly shaped metal chains to rotate slowly through the support arm, so that the irregularly shaped metal chains react evenly and comprehensively with the chemical solution, thereby effectively removing burrs. This chemical deburring device allows the chains to fully contact the chemical liquid phase during use, thereby completely and effectively removing burrs, resulting in very good performance.
