Description

Technical Field

[0001] This invention relates to the field of deburring technology, and more specifically to a device for treating burrs on stamped parts. Background Technology

[0002] Stamping is a forming process that uses pressure to deform sheet metal, strip, tube, and profile. Stamped parts come in various shapes, each with its own unique application, such as square, rhomboid, and ring shapes. Among these, ring-shaped stamped parts have a wider range of applications, covering multiple manufacturing fields. However, during the mass production of these ring-shaped stamped parts, some burrs inevitably form on their surface, which affects the product's usability and necessitates the use of burr removal equipment.

[0003] Existing deburring devices for stamped parts mainly consist of a stamped part fixing mechanism, a surface grinding mechanism, a hole grinding mechanism, and a conveying mechanism. The stamped part to be deburred is mounted on top of the fixing mechanism, and the hole grinding mechanism grinds the burrs on the inner ring sidewall of the annular stamped part. Afterward, it is removed and placed in the conveying mechanism, which then uses braking to pass the stamped part sequentially through multiple sets of surface grinding mechanisms for progressively deeper and finer grinding of the outer surface to remove surface burrs. Because the hole grinding mechanism and the surface grinding mechanism are relatively independent, after the hole grinding mechanism completes its work, workers still need to transfer the part to the next grinding stage, which involves a certain amount of physical labor and prevents integrated, all-around deburring.

[0004] Furthermore, although the conveying mechanism can deburr at a uniform speed, for stamped parts with many surface burrs, the lack of limiting components during the surface grinding process makes the position of the stamped parts unstable, which to some extent affects the uniform shaving of the stamped parts surface. In addition, during the grinding process, the grinding disc of the surface grinding mechanism is prone to overheating due to prolonged friction with the stamped parts, and the grinding process is not smooth enough, which to some extent wears down the grinding disc. Moreover, the burr waste generated by the stamped parts during the grinding process will fly around, affecting the workshop environment and posing certain safety hazards to the workers.

[0005] Therefore, there is an urgent need for a new type of device for handling burrs on stamped parts. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a device for burr removal of stamped parts to solve the problems existing in the background art.

[0017] Preferably, the output shaft of the second brake motor, the fixed pin head, and the movable pin seat are arranged on the same central axis of the device, that is, the center of the fixed pin head is accurately aligned with the movable pin seat, the bottom surface of the fixed pin head is provided with a small protrusion, and the top of the movable pin seat is provided with a hole groove that matches the outer volume of the fixed pin head.

[0018] Preferably, when the fixed pin head is fully inserted into the movable pin seat, the grinding disc reaches the grinding depth required for the surface of the stamped part.

[0019] Preferably, the side grinding mechanism includes an L-shaped frame, with a buffer pad fixedly connected to the top of the L-shaped frame and the bottom of the L-shaped frame fixedly connected to the outer wall of the main housing. One side of the buffer pad is connected to the grinding block via an elastic telescopic rod. The bottom of the grinding block is fixedly connected to the balance block via a longitudinal rod. The grinding block, longitudinal rod, and balance block are kept on the same longitudinal axis on the side closest to the main unit. The balance block is connected to the L-shaped frame via a main spring. The middle part of the L-shaped frame on the side closest to the longitudinal rod is engaged with a buckle fixedly connected to the inner side of the longitudinal rod via a hook lock.

[0020] Preferably, the grinding block, the longitudinal bar, and the balance block are kept on the same longitudinal axis on the side closest to the main unit, so as to ensure that the grinding depth of the grinding block is controlled by the cooperation of the longitudinal bar and the limiting mechanism.

[0022] Preferably, the opening and closing mechanism includes a U-shaped frame and two second electric push rods.

[0023] Preferably, the two sliding rods are movably connected to the U-shaped frame at one end near the U-shaped frame, and the side wall of the U-shaped frame is provided with a longitudinal groove that matches the end of the sliding rod.

[0024] The technical effects and advantages of this invention are as follows:

[0025] 1. This invention, by incorporating a main unit, a surface grinding mechanism, and a side grinding mechanism, facilitates the grinding of the side walls of the stamped part after it is placed on the worktable at the top of the main housing. The lower and upper covers then merge to form a sealed cavity for grinding the surface of the stamped part. When the surface grinding mechanism descends to the top of the stamped part, a fixed pin engages with the inner cavity of the movable pin seat. This fixed pin then drives the movable pin seat to rotate within the through-hole in the center of the annular stamped part, removing burrs from the through-hole. This achieves continuous, integrated, all-around, and uniform burr removal, further reducing manual labor.

[0026] 2. This invention, by incorporating a main unit, a surface grinding mechanism, and a circulating oil supply mechanism, facilitates the use of a movable pin to limit the stamped part placed on the top worktable of the main unit, with the central portion penetrated by the movable pin. The part is then ground by a grinding disc within a sealed cavity enclosed by the lower and upper covers. The resulting burrs and waste are collected within the defined area. During grinding, lubricating oil is supplied to the area enclosed by the lower cover and the grinding disc via an oil supply pipe. The lubricating oil then flows back to the inner cavity of the oil tank via a return oil pipe, completing the recovery of waste and the recycling of lubricating oil. The above-mentioned design offers several advantages: the movable pin ensures that the stamped part does not shift during grinding; it avoids environmental pollution caused by burrs and waste splashing everywhere and ensures the safety of workers; it reduces the surface temperature of the grinding disc while grinding the stamped part and lubricates the grinding process (protecting the friction disc and extending its service life); and it also achieves the recovery of burrs and scrap and the recycling of lubricating oil.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The burr removal device for stamped parts involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Reference Figure 1-2 The present invention provides a device for treating burrs on stamped parts, including a main unit 1, an opening and closing mechanism 2 installed on one side of the main unit 1, a surface grinding mechanism 4 installed on the top and bottom of the opening and closing mechanism 2 via a sliding rod 3, the bottom of the surface grinding mechanism 4 being movably connected to the main unit 1, a side grinding mechanism 5 installed on the other side of the main unit 1, and a circulating oil supply mechanism 6 installed on the back of the main unit 1.

[0039] In this embodiment, it should be specifically noted that this embodiment is based on... Figure 1 The perspective shown is the main perspective. The description of the circulating oil supply mechanism 6 being installed on the back of the main unit 1 is only for the purpose of distinguishing the installation position of the circulating oil supply mechanism 6 relative to the opening and closing mechanism 2 and the side grinding mechanism 5 on the outer surface of the main unit 1. This front and back perspective setting is fictitious, that is, the installation position of the circulating oil supply mechanism 6 can be the front or the back of the main unit 1.

[0040] Reference Figure 3 and Figure 4 The main unit 1 includes a main housing 101. The top surface of the outer wall of the main housing 101 is set as a workbench. The bottom of the main housing 101 is supported by a base 102. A braking assembly 103 is installed in the middle of the inner cavity of the main housing 101. A lower cover 104, which is fixedly connected to the sliding rod 3, is movably sleeved in the middle of the outer wall of the main housing 101. A limit mechanism 105 is installed on the top of the inner cavity of the main housing 101 near the side grinding mechanism 5. A movable pin seat 106 is movably sleeved on the top of the workbench set on the top of the outer wall of the main housing 101.

[0041] The braking assembly 103 includes a first brake motor 1031, a first gear 1032 is fixedly sleeved on the output shaft at the top of the first brake motor 1031, a bearing 1033 is fixedly sleeved on the center of the bottom surface of the inner cavity of the main housing 101, a transmission shaft 1034 is fixedly sleeved on the inner side wall of the bearing 1033, and the top of the transmission shaft 1034 passes through the top wall of the main housing 101 and is fixedly connected to the workbench placed on the top of the main housing 101. A second gear 1035 that meshes with the first gear 1032 is fixedly sleeved on the bottom of the surface of the transmission shaft 1034.

[0042] In this embodiment, it should be specifically explained that the top end of the drive shaft 1034 penetrates the wall of the main housing 101 and is in a movable sleeve relationship with it, thereby the drive shaft 1034 brakes and drives the worktable located on the top surface of the main housing 101 to rotate.

[0043] The top of the workbench has an insertion hole that matches the movable pin seat 106, so that the movable pin seat 106 can be movably inserted into the top of the workbench.

[0044] Reference Figure 3 and Figure 5 The limiting mechanism 105 includes a first electric push rod 1051, which is fixedly installed on the inner wall of the main housing 101 via a first support frame 1052. The movable end of the first electric push rod 1051 is fixedly connected to a limiting block 1053, and an infrared laser lamp 1054 is fixedly installed on the top of the limiting block 1053 on the side away from the first electric push rod 1051.

[0045] In this embodiment, it should be specifically noted that the installation position of the limiting mechanism 105 on the inner wall of the main housing 101 is determined by the setting position of the side grinding mechanism 5. The side wall of the main housing 101 is provided with an opening that matches the limiting block 1053, so that the moving end of the first electric push rod 1051 can be braked to drive the limiting block 1053 to extend out or retract from the inside of the main housing 101.

[0046] Reference Figure 3 and Figure 6 The surface polishing mechanism 4 includes a second brake motor 401. The second brake motor 401 is fixedly installed on the top of the upper cover 403 via a second support frame 402. The output shaft at the bottom of the second brake motor 401 is fixedly sleeved with a polishing disc 404 located inside the upper cover 403 via a coupling. A fixing pin 405 is fixedly sleeved at the center of the bottom of the polishing disc 404.

[0047] In this embodiment, it should be specifically noted that the output shaft of the second brake motor 401, the fixed pin head 405, and the movable pin seat 106 are arranged on the same central axis of the device. That is, the center of the fixed pin head 405 is accurately aligned with the movable pin seat 106. The bottom surface of the fixed pin head 405 is provided with a small protrusion, and the top of the movable pin seat 106 is provided with a hole groove that matches the outer volume of the fixed pin head 405. This facilitates the insertion of the fixed pin head 405 into the top of the movable pin seat 106, and the two are locked together. The fixed pin head 405 connected to the bottom of the grinding disc 404 drives the movable pin seat 106, which is locked with it, to rotate along the inner wall of the through hole in the center of the annular stamping part to remove burrs from the inner wall of the through hole.

[0048] When the fixed pin 405 is fully inserted into the movable pin seat 106, the grinding disc 404 reaches the grinding depth required for the surface of the stamped part.

[0049] Reference Figure 7 and Figure 8 The side grinding mechanism 5 includes an L-shaped frame 501. A buffer pad 502 is fixedly connected to the top of the L-shaped frame 501, and the bottom of the L-shaped frame 501 is fixedly connected to the outer wall of the main housing 101. One side of the buffer pad 502 is connected to the grinding block 504 via an elastic telescopic rod 503. The bottom of the grinding block 504 is fixedly connected to the balance block 506 via a longitudinal rod 505. The grinding block 504, the longitudinal rod 505, and the balance block 506 are kept on the same longitudinal axis on the side near the main unit 1. The balance block 506 is connected to the L-shaped frame 501 via a main spring 507. The middle part of the L-shaped frame 501 on the side near the longitudinal rod 505 is engaged with the buckle 509 fixedly connected to the inner side of the longitudinal rod 505 via a hook lock 508.

[0050] In this embodiment, it should be specifically noted that the grinding block 504, the longitudinal rod 505 and the balance block 506 are kept on the same longitudinal axis on the side close to the main unit 1, so as to ensure that the grinding depth of the grinding block 504 is controlled by the cooperation of the longitudinal rod 505 and the limiting mechanism 105.

[0051] The elastic telescopic rod 503 includes a cavity 5031, a movable rod 5032, and an auxiliary spring 5033. The movable rod 5032 is movably sleeved in the inner cavity of the cavity 5031. One end of the auxiliary spring 5033 is fixedly connected to the inner wall of the cavity 5031, and the other end is fixedly connected to the movable rod 5032, which serves to support and push the grinding block 504.

[0052] Reference Figure 3 and Figure 9 The opening and closing mechanism 2 includes a U-shaped frame 201 and two second electric push rods 202. The top and bottom of the U-shaped frame 201 are fixedly connected to the fixed ends of the two second electric push rods 202. The movable ends of the two second electric push rods 202 are fixedly connected to the side walls of the upper cover 403 and the lower cover 104 respectively through sliding rods 3.

[0053] In this embodiment, it should be specifically noted that the two sliding rods 3 are movably connected to the U-shaped frame 201 at one end, and the side wall of the U-shaped frame 201 is provided with a longitudinal groove that matches the end of the sliding rod 3, so as to ensure that the sliding rod 3 moves up and down along the longitudinal groove of the U-shaped frame 201 without falling off.

[0054] Reference Figure 1 and Figure 2 The circulating oil supply mechanism 6 includes an oil tank 601. The top of the oil tank 601 is fixedly connected to the lower cover 104 through a return oil pipe 602. The bottom of the oil tank 601 is fixedly connected to an oil supply pipe 603, and the top of the oil supply pipe 603 extends to the top wall of the upper cover 403 and passes through it. An oil pump 604 is provided at the bottom of the oil supply pipe 603.

[0055] Working principle of this invention:

[0056] S1, Side wall grinding stage: The movable pin 106 limits the stamping part placed on the top worktable of the main unit 1 and penetrated by the movable pin 106 in the middle, and the side wall is ground by opening the side grinding mechanism 5.

[0057] Specifically, the operation steps are as follows: the brake assembly 103 is turned on, the output shaft of the first brake motor 1031 drives the first gear 1032, which is fixedly sleeved with it, to rotate, the first gear 1032 drives the second gear 1035, which meshes with it, to rotate, and the second gear 1035 drives the transmission shaft 1034, which is fixedly sleeved with it, to rotate in the inner cavity of the main housing 101 through the bearing 1033.

[0058] Furthermore, before the side grinding mechanism 5 is activated, the hook end of the hook lock 508 is engaged in the buckle 509 fixedly connected to the side wall of the longitudinal rod 505. The pulling force provided by the hook lock 508 restricts the position of the grinding block 504 and the balance block 506, that is, it pulls the grinding block 504 and the balance block 506 closer to the side of the L-shaped frame 501. When the side grinding mechanism 5 is activated, the hook end of the hook lock 508 is removed from the buckle 509. At this time, the grinding block 504 and the balance block 506 move closer to the stamping part under the elastic force of the main spring 507 and the elastic telescopic rod 503. At this time, the limiting mechanism 105 is adjusted to the pre-grinding position. The grinding block 504 then touches the stamped part placed on the top of the main housing 101 and grinds its outer surface until the longitudinal rod 505 touches the limiting block 1053 outside the limiting mechanism 105. At this time, the grinding block 504 also reaches the critical value of grinding and cannot continue to grind deeper. This completes the deburring process of the side wall of the stamped part. After this process is completed, the buckle 509 on the side wall of the longitudinal rod 505 is dragged and re-engaged with the hook of the hook lock 508. At the same time, the first electric push rod 1051 is controlled to bring the first support frame 1052 back into the inner cavity of the main housing 101 (returned to process), preparing for the next stage.

[0059] S2. Surface and hole grinding stage: The lower cover 104 and the upper cover 403 are combined to form a sealed cavity for grinding the surface of the stamped part. When the surface grinding mechanism 4 descends to the top of the stamped part, the fixed pin head 405 is engaged in the inner cavity of the movable pin seat 106. Then the fixed pin head 405 drives the movable pin seat 106 to rotate in the inner wall of the through hole in the center of the annular stamped part to remove burrs from the inner wall of the through hole.

[0060] The specific operating steps are as follows: the second electric push rods 202 installed at the top and bottom of the U-shaped frame 201 are activated. Then, the movable ends of the two second electric push rods 202 drive the upper cover 403 and the lower cover 104 connected to them to converge towards the workbench at the top of the main box 101 through the sliding rod 3. After the top surface of the lower cover 104 is in contact with the bottom surface of the upper cover 403, the two second electric push rods 202 stop braking. At this time, the lower cover 104 and the upper cover 403 form a sealed chamber. At this time, the fixed pin head 405 is inserted into the inner wall of the movable pin seat 106, and the two are in a snap-fit ​​relationship.

[0061] Furthermore, the second brake motor 401, which is mounted on the top of the upper cover 403 via the second support frame 402, is activated for braking. The output shaft of the second brake motor 401 drives the grinding disc 404, which is fixedly sleeved with it, to rotate. The grinding disc 404 grinds the surface of the stamped part. At the same time, the fixed pin head 405 connected to the bottom of the grinding disc 404 drives the movable pin seat 106, which is engaged with it, to rotate along the inner wall of the through hole in the center of the annular stamped part to remove burrs from the inner wall of the through hole. The burrs and scraps generated during the grinding process are concentrated in the cavity enclosed by the lower cover 104 and the upper cover 403.

[0062] S3. Flushing and recycling stage: During the grinding process, lubricating oil is supplied to the enclosed area formed by the lower cover 104 and the grinding disc 404 through the oil supply pipe 603. Then, the burrs and scraps are flushed into the lower cover 104. After that, the lubricating oil flows back to the inner cavity of the oil tank 601 through the return oil pipe 602, completing the recycling of waste materials and the recycling of lubricating oil.

[0063] S4, the secondary surface grinding stage of the stamped part.

[0064] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
