Abstract
Description
Technical Field
[0001] This utility model belongs to the field of metal sheet polishing technology, specifically relating to an automatic metal sheet edge polishing device. Background Technology
[0002] Currently, most metal containers are formed using a stamping process from metal discs. Before the stamping process, the outer edges of the metal discs need to be ground to ensure a smooth and regular edge, meeting the precision requirements of subsequent stamping. The conventional grinding method involves placing the metal disc on a high-speed rotating support plate. A shaft driving the rotation is connected below the support plate, and an electromagnet is installed at the center of the support plate. During loading, a suction cup conveying mechanism concentrically places the metal disc above the support plate. Then, the electromagnet is energized to generate magnetic force, stably attracting and fixing the disc. Simultaneously, the shaft rotates at high speed, causing the support plate and metal disc to rotate synchronously at high speed. The grinding mechanism on one side gradually moves towards the edge of the disc until the grinding component is in close contact with the edge, using the high-speed rotation of the disc to complete the continuous grinding operation. After grinding, the electromagnet is de-energized, releasing the disc from its attraction. The suction cup conveying mechanism then transfers the successfully ground disc to the next process.
[0003] However, during long-term continuous grinding operations, a large amount of iron filings will be generated on the edge of the metal disc. Since the electromagnet is magnetic when energized, it will continuously attract the scattered iron filings. As the equipment is used for a longer period of time, a large amount of iron filings will gradually accumulate on the surface of the electromagnet. If it is not cleaned in time, the accumulated iron filings will affect the flatness of the electromagnet's attraction and the magnetic conduction, thereby reducing the attraction and fixation effect on the metal disc. This may cause problems such as the disc shifting or shaking when rotating at high speed, affecting the grinding accuracy and processing stability. Utility Model Content
[0004] The purpose of this invention is to provide an automatic metal sheet edge grinding device to solve the problems existing in the background art.
[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:
[0006] An automatic metal sheet edge grinding device includes a worktable, a rotating shaft driven and mounted on the upper side of the worktable, a support plate on the upper side of the rotating shaft, an electromagnet on the middle side of the support plate, a mounting frame on the upper side of the worktable, a sliding groove within the mounting frame, a sliding seat slidably mounted within the sliding groove, a grinding mechanism on the upper side of the sliding seat, a sealing frame on the side of the sliding groove away from the rotating shaft, a one-way air inlet valve on the rear side of the sealing frame, a one-way air outlet mechanism on the rear side of the sealing frame, the output end of the one-way air outlet mechanism pointing towards the upper surface of the electromagnet, a sliding plate slidably sealed and mounted within the sealing frame, a spring-loaded mechanism on the rear side of the sliding plate, and a contact mechanism matching the sliding seat on the other side of the sliding plate.
[0007] The contact mechanism includes two push rods, one end of which is connected to the slide plate, and the other end of which slides into the slide groove and is fitted with a top plate that matches the sliding seat. The mounting frame has two through holes through which the push rods pass and communicate with the inside of the sealing frame.
[0008] The rebound mechanism includes two telescopic rods and two first springs. The two telescopic rods are respectively connected to both sides of the slide plate, and the other end of each telescopic rod is connected to the inner wall of the sealing frame. The two first springs are respectively sleeved on the outer surface of the two telescopic rods.
[0009] The one-way air outlet mechanism includes a connecting pipe that communicates with the inside of the sealing frame, the connecting pipe is equipped with a one-way air outlet valve, and the end of the connecting pipe is equipped with a nozzle that points towards the electromagnet.
[0010] The workbench is provided with a support seat on one side of the rotating shaft. The upper side of the support seat is provided with a cavity. A second spring is provided in the cavity. A slider that slides up and down in the cavity is connected to the upper side of the second spring. A connecting rod that slides out of the support seat is provided on the upper side of the slider. The upper end of the connecting rod is connected to the nozzle.
[0011] The nozzle is equipped with a stabilizing wheel on its upper side.
[0012] Two limiting rods are installed inside the slide groove, and the two sides of the sliding seat are respectively sleeved on the outer surface of the two limiting rods.
[0013] A cylinder is also provided on the side of the mounting frame away from the rotating shaft, and the output end of the cylinder is connected to the sliding seat.
[0014] The grinding mechanism includes a motor mounted on the upper side of the sliding seat, and a grinding disc is mounted on the output end of the motor.
[0015] This utility model has the following technical advantages compared with the prior art:
[0016] In grinding operations, precise positioning and stable fixation of the metal disc are crucial. This device uses a suction cup feeding mechanism to precisely transport the metal disc to be ground onto the support plate, ensuring strict concentricity between them. Then, an electromagnet is energized, generating a stable magnetic force that firmly holds the metal disc in place. As the high-speed rotation of the shaft drives the metal disc to rotate, the electromagnet's continuous attraction effectively prevents radial displacement, wobbling, or slippage of the metal disc, providing a stable workpiece for the grinding mechanism. This ensures the precision of the grinding operation, resulting in a high-quality edge for the ground metal disc.
[0017] This device automates the entire process from loading, grinding, unloading, and cleaning. During loading, a suction cup conveying mechanism automatically transports and positions the metal disc. During grinding, the sliding seat, driven by a cylinder, smoothly feeds along the groove, ensuring full contact between the grinding mechanism and the edge of the metal disc for continuous grinding. It automatically resets upon completion. During unloading, the electromagnet is de-energized, and the suction cup conveying mechanism operates again to transfer the finished disc for unloading. Furthermore, the automatic cleaning function is triggered during the sliding seat's reset process after the metal disc is removed, requiring no additional manual intervention.
[0018] This device cleverly incorporates an automatic cleaning function. When the sliding seat resets, a contact mechanism drives the slide plate to slide within the sealed frame, and compressed air is blown onto the electromagnet surface through a one-way air outlet mechanism, thoroughly removing iron filings. When the sliding seat moves again, a rebound mechanism causes the slide plate to reset, creating negative pressure and drawing in outside air to replenish it, preparing for the next air blowing cleaning. This function effectively maintains the cleanliness of the device's interior.
[0019] The sliding groove is equipped with a limiting rod, and the two sides of the sliding seat are sleeved on the outer surface of the limiting rod, which effectively improves the sliding stability of the sliding seat and avoids deviation or jamming during reciprocating motion. The nozzle is connected to the support seat through the connecting rod, slider and second spring. When the metal disc is attracted to the electromagnet, the nozzle can move downward without affecting the processing of the metal disc. After the metal disc is removed, it can automatically reset. The design of the stabilizing wheel ensures flexible contact between the metal disc and the connecting rod when rotating, which further enhances the stability of the device operation and ensures the smooth progress of the grinding operation.

Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0029] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.
[0030] like Figure 1-4As shown, this utility model discloses an automatic metal sheet edge grinding device, comprising a worktable 1. The worktable 1 is characterized by: a rotating shaft 11 driven onto its upper side; a support plate 12 on the upper side of the rotating shaft 11; an electromagnet 13 in the middle of the support plate 12; a mounting frame 2 on the upper side of the worktable 1; a sliding groove 21 within the mounting frame 2; a sliding seat 22 slidably mounted within the sliding groove 21; a grinding mechanism on the upper side of the sliding seat 22; a sealing frame 23 on the side of the sliding groove 21 away from the rotating shaft 11; a one-way air inlet valve 24 on the rear side of the sealing frame 23; a one-way air outlet mechanism on the rear side of the sealing frame 23; the output end of the one-way air outlet mechanism pointing towards the upper surface of the electromagnet 13; a sliding plate 25 slidably and sealingly mounted within the sealing frame 23; a spring-back mechanism on the rear side of the sliding plate 25; and a contact mechanism matching the sliding seat 22 on the other side of the sliding plate 25.
[0031] The rotating shaft 11 stably drives the support plate 12 to rotate at high speed. During the feeding stage, the suction cup feeding mechanism accurately transports the metal disc to be ground onto the upper surface of the support plate 12, and the positioning control ensures that the metal disc and the support plate 12 are strictly concentrically arranged. At this time, the electromagnet 13 at the center position is energized, causing its surface to generate a stable magnetic attraction force, firmly adsorbing and fixing the metal disc. After the adsorption and positioning are completed, the rotating shaft 11 starts to rotate at high speed. Through the synchronous drive of the support plate 12 and the electromagnet 13, the metal disc is kept rotating smoothly at high speed. The continuous adsorption force provided by the electromagnet 13 can effectively prevent the metal disc from radially shifting, shaking or slipping during high-speed rotation, ensuring the accuracy and safety of the grinding operation.
[0032] The mounting frame 2 has a groove 21, and the sliding seat 22 is fitted inside the groove 21 and can reciprocate. During the grinding operation, the sliding seat 22 is smoothly fed along the groove 21 towards the support plate 12 until the grinding mechanism installed on the upper part of the sliding seat 22 is in full contact with the edge of the metal disc, and the side of the disc is continuously ground and trimmed. After the edge grinding process of the metal disc is completed, the sliding seat 22 moves in the opposite direction along the groove 21 to reset, and the rotation speed of the rotating shaft 11 gradually decreases until it stops completely. After the rotating shaft 11 stops, the electromagnet 13 is de-energized and demagnetized, releasing the adsorption and fixation on the metal disc. The finished disc is naturally placed on the support plate 12, and then the suction cup material conveying mechanism transfers the finished disc for unloading, so that the upper surface of the support plate 12 and the electromagnet 13 is completely exposed.
[0033] After the metal disc is removed, during the reset movement of the sliding seat 22, its end will engage with the corresponding contact mechanism. As the sliding seat 22 continues to move in the reset direction, it will push the slide plate 25 to slide directionally inside the sealing frame 23. At this time, the spring mechanism on the outside of the sealing frame 23 is compressed and undergoes elastic contraction, thereby compressing the air inside the cavity of the sealing frame 23. The compressed gas is blown out directionally through the one-way air outlet mechanism, and the airflow acts directly on the surface of the electromagnet 13. At this time, there is no metal disc obstructing the electromagnet 13, and the high-pressure airflow can fully sweep away the iron filings attached to its surface, completely blowing away the accumulated debris and achieving automatic cleaning. When the sliding seat 22 moves again in the grinding direction and away from the sealing frame 23, the spring mechanism loses pressure and gradually extends and resets, simultaneously driving the slide plate 25 to move back and reset. During the retraction of the slide plate 25, a negative pressure environment is formed inside the sealing frame 23, and outside air is then replenished and drawn into the cavity of the sealing frame 23 through the one-way air inlet valve 24, preparing for the next air blowing cleaning.
[0034] The contact mechanism includes two push rods 3, one end of which is connected to the slide plate 25, and the other end of which slides into the slide groove 21 and is fitted with a top plate 31 that matches the sliding seat 22. The mounting frame 2 is provided with two through holes 32 through which the push rods 3 pass and communicate with the interior of the sealing frame 23.
[0035] The push rod 3 connects the slide plate 25 and the top plate 31. When the sliding seat 22 contacts the top plate 31 during sliding, the top plate 31 drives the slide plate 25 to start moving through the push rod 3. The slide plate 25 can drive the spring mechanism to start compressing, and the air in the sealing frame 23 can be squeezed through the slide plate 25. With this design, when the sliding seat 22 stops contacting the top plate 31, the slide plate 25 can be reset under the action of the spring mechanism.
[0036] The rebound mechanism includes two telescopic rods 33 and two first springs 331. The two telescopic rods 33 are respectively connected to both sides of the slide plate 25, and the other end of the two telescopic rods 33 is connected to the inner wall of the sealing frame 23. The two first springs 331 are respectively sleeved on the outer surface of the two telescopic rods 33.
[0037] When the slide plate 25 begins to move and compress the air in the sealing frame 23 under the action of the top rod 3, it can drive the first spring 331 and the telescopic rod 33 to compress. When the slide plate 25 needs to be reset, it can be pushed to reset and move under the action of the first spring 331, forming a negative pressure inside the sealing frame 23 on the side away from the rotating shaft 11, drawing external gas into the sealing frame 23.
[0038] The one-way air outlet mechanism includes a connecting pipe 34 that communicates with the inside of the sealing frame 23, a one-way air outlet valve 35 is installed on the connecting pipe 34, and a nozzle 36 pointing to the electromagnet 13 is installed at the end of the connecting pipe 34.
[0039] When the gas in the sealing frame 23 is pumped out, it directly enters the connecting pipe 34. The connecting pipe 34 pumps the gas into the nozzle 36, which then delivers the gas into the nozzle 36. The nozzle 36 sprays the gas onto the surface of the electromagnet 13 to clean the surface of the electromagnet 13.
[0040] The workbench 1 has a support base 4 located on one side of the rotating shaft 11. The support base 4 has a cavity 41 on its upper side. A second spring 42 is installed in the cavity 41. A slider 43 is connected to the upper side of the second spring 42 and is slidably mounted in the cavity 41. A connecting rod 44 is provided on the upper side of the slider 43 and extends out of the support base 4. The upper end of the connecting rod 44 is connected to the nozzle 36.
[0041] The nozzle 36 is located on the upper side of the connecting rod 44. When the metal disc is attracted to the upper side of the electromagnet 13, it can contact the upper side of the connecting rod 44 from above, squeezing the connecting rod 44 to move downward. The connecting rod 44 pushes the slider 43 to move downward, causing the second spring 42 to start compressing. This ensures that when the metal disc is on the upper side of the electromagnet 13, the nozzle 36 will move downward. The nozzle 36 is located on the lower side of the support plate 12, so it will not affect the processing of the metal disc. When the metal disc is removed from the upper side of the electromagnet 13, the slider 43 can be driven to move upward under the action of the extension of the second spring 42. The slider 43 then drives the nozzle 36 to move upward and reset through the connecting rod 44.
[0042] A stabilizing wheel 45 is provided on the upper side of the nozzle 36. The stabilizing wheel 45 is designed to make close contact with the metal disc. When the metal disc rotates, the stabilizing wheel 45 starts to rotate, which can ensure that the metal disc does not make hard contact with the connecting rod 44.
[0043] Two limiting rods 5 are installed inside the slide groove 21, and the two sides of the sliding seat 22 are respectively fitted onto the outer surfaces of the two limiting rods 5. The design of the two sides of the sliding seat 22 being fitted onto the outer surfaces of the two limiting rods 5 can improve the sliding stability of the sliding seat 22.
[0044] A cylinder 51 is also provided on the side of the mounting frame away from the rotating shaft 11. The output end of the cylinder 51 is connected to the sliding seat 22. The extension and retraction of the cylinder 51 can drive the sliding seat 22 to slide.
[0045] The polishing mechanism includes a motor 52 located on the upper side of the sliding seat 22, and a polishing disc 53 is mounted on the output end of the motor 52.
[0046] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
