Description

An automatic feeding and grinding device Technical Field

[0001] This utility model relates to the technical field of grinding devices, and in particular to an automatic feeding grinding device. Background Technology

[0002] After the cover-type workpiece is formed by aluminum die casting, the workpiece is provided with a mounting groove. There are four through holes on one side of the bottom of the mounting groove and two through holes on the other side. A positioning hole is provided in the middle of the bottom of the mounting groove. After the workpiece is formed, there are burrs at the positioning hole position, which need to be deburred and then polished.

[0003] The existing method requires manual deburring of the workpiece, followed by grinding with a grinder, and then using a file to sharpen or deburr the edges of the holes. This method is labor-intensive and results in poor grinding quality. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic feeding and grinding device. It solves the technical problem of multiple grinding steps for cover-type workpieces and the need for secondary removal of sharp edges on the workpiece's openings.

[0005] To achieve the above objectives, the solution adopted by this utility model is: an automatic feeding and grinding device, comprising;

[0006] A feeding device, comprising a feeding frame, a rotating mechanism, and a pallet frame, wherein the rotating mechanism is disposed between the pallet frame and the feeding frame, and drives the pallet frame to rotate, and the pallet frame is used to support and position multiple workpieces;

[0007] A hole edge cleaning mechanism is provided on the feeding device. The hole edge cleaning mechanism is equipped with a file, and the outer periphery of the file has a frosted structure.

[0008] A grinding mill device, spaced apart from the feeding device, is used to grind the edges and surfaces of workpieces;

[0009] A robotic arm assembly moves between the feeding device and the grinding device, gripping the workpiece from the feeding device and moving between the file and the grinding device.

[0010] In this solution, by setting up a feeding device, the workpiece is positioned on the feeding device. After the robotic arm component moves to grab the workpiece on the feeding device, it moves it to the file to deburr the positioning hole of the workpiece. After deburring, the robotic arm component drives the workpiece to the grinding device to grind it. Deburring and grinding are carried out automatically in one piece, which not only saves manpower but also makes the grinding effect better.

[0011] Preferably, the pallet frame is located above the feeder frame, and the pallet frame is provided with multiple positioning areas for accommodating and positioning workpieces at intervals around the rotation center line of the rotating mechanism.

[0012] In this solution, a rotating mechanism is set up to drive the pallet frame to rotate, so that each positioning area can move to the gripping position, and each workpiece can be moved to a fixed position, which is convenient for the robot arm component to grip and process it.

[0013] As a further preferred embodiment, the pallet frame is provided with two positioning areas in the same radial direction, and the length directions of the two positioning areas intersect.

[0014] In this solution, multiple workpieces can be positioned simultaneously by setting multiple positioning points, which can save processing time.

[0015] As a further preferred embodiment, each of the positioning areas is provided with a plurality of positioning posts, which are used for inserting and positioning the workpiece.

[0016] In this solution, the workpiece is positioned better by inserting a positioning pin into the positioning hole of the workpiece, making the positioning position of the workpiece more accurate and preventing it from moving around.

[0017] As a further preferred embodiment, the hole edge cleaning mechanism is located on the feeding rack and outside the rotation area of ​​the pallet rack.

[0018] In this solution, the workpiece is positioned by setting up a pallet frame, and the hole edge cleaning mechanism is set on the feeding frame, so that the file is placed near the pallet frame, which facilitates the deburring of the workpiece.

[0019] As a further preferred embodiment, the grinding mill device includes a grinding component and a grinding box. The grinding component is disposed inside the grinding box. After the robotic arm component grasps the workpiece, it transports it to the grinding component to grind the workpiece.

[0020] In this solution, a grinding component is used to grind the workpiece, making the edge surface of the workpiece smooth.

[0021] As a further preferred embodiment, the polishing assembly includes a first drive mechanism and a first polishing belt. The first drive mechanism is provided on one side of the polishing box, and the first polishing belt is provided on the first drive mechanism and connected to the first drive mechanism.

[0022] In this scheme, the first driving mechanism drives the first grinding belt to perform the first rough grinding of the workpiece.

[0033] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0034] As shown in Figures 1 and 2, this utility model discloses an automatic feeding and grinding device, which is mounted on a base platform 1. The automatic feeding and grinding device includes a feeding device 2, a hole edge cleaning mechanism 3, a grinding mill device 5, and a robotic arm assembly 6. The feeding device 2 is mounted on the base platform 1 and is used to position the workpiece 9. The hole edge cleaning mechanism 3 is mounted on the feeding device 2, and a file 4 is mounted on the hole edge cleaning mechanism 3. The outer periphery of the file 4 has a frosted structure. The grinding mill device 5, used for grinding the workpiece 9, is mounted on the base platform 1. The robotic arm assembly 6 is mounted on the base platform 1 and is used to grip the workpiece 9 from the feeding device 2 and move it to the file 4 to remove burrs.

[0035] Furthermore, as a preferred embodiment, the feeding device 2 includes a feeding rack 21 and a tray rack 22. The feeding rack 21 is provided on the base platform 1, and the upper end of the feeding rack 21 is provided with the tray rack 22. The tray rack 22 is used to position the workpiece 9, and the hole edge cleaning mechanism 3 is provided on the feeding rack 21.

[0036] Furthermore, as a preferred embodiment, the pallet frame 22 is provided with multiple positioning areas 23, and each positioning area 23 can position a workpiece 9.

[0037] Furthermore, as a preferred embodiment, each positioning area 23 is provided with a plurality of positioning posts 24, which are inserted into the through holes of the workpiece 9 to position it.

[0038] Furthermore, as a preferred embodiment, a rotating mechanism 25 is provided between the pallet frame 22 and the feeder 21, and the rotating mechanism 25 drives the pallet frame 22 to rotate.

[0039] Furthermore, as a preferred embodiment, it also includes a pressure plate 7, with a support 8 provided at the upper end of the base platform 1, and a pressure plate 7 provided at the upper end of the support 8, and the pressure plate 7 is inclined.

[0040] Specifically, in this embodiment, a feeding device 2, a grinding mill device 5, and a robotic arm assembly 6 are provided on the upper end of the base platform 1. The robotic arm assembly 6 is provided on one side of the feeding device 2, and the grinding mill device 5 is provided on one side of the robotic arm assembly 6. The feeding device 2 includes a feeding rack 21 and a pallet rack 22. The feeding rack 21 is located on the base platform 1, and a rotating mechanism 25 is provided on the upper end of the feeding rack 21.

[0041] As shown in Figures 2 to 4, a pallet frame 22 is provided on the rotating mechanism 25. The pallet frame 22 has multiple sections forming eight positioning areas. Each of the eight positioning areas is composed of two positioning zones 23 joined together horizontally and vertically. Each positioning zone 23 positions one workpiece 9. Two workpieces 9 can be placed in each of the eight positioning areas. The rotating mechanism 25 is a rotating motor. One position on the pallet frame 22 near the robot arm assembly 6 is the gripping area. The rotating mechanism 25 drives the pallet frame 22 to rotate any one of the positioning zones 23 to the gripping area for the robot arm assembly 6 to grip the workpiece 9 on it. Each positioning zone 23 has four positioning posts 24 on one side and two positioning posts 24 on the other side. A total of six positioning posts 24 are provided on each positioning zone 23. Similarly, each positioning area has twelve positioning posts 24. Each positioning post 24 is inserted into a through hole of the workpiece 9 to position the workpiece 9.

[0042] A hole edge cleaning mechanism 3 is provided on one side of the feeding rack 21. The hole edge cleaning mechanism 3 is an L-shaped plate, and a file 4 is connected to the upper end of the L-shaped plate. The outer periphery of the file 4 has a frosted structure, which is similar to the sanding surface of sandpaper. The frosted structure is existing technology. The diameter of the file 4 gradually increases from top to bottom. The workpiece 9 moves downward along the upper end of the file 4 under the grip of the robot arm assembly 6. During this process, the frosted structure on the outer periphery of the file 4 smooths the edge of the positioning hole, thereby removing the burrs near the formed positioning hole.

[0043] The robotic arm component 6 is existing technology, so it will not be described in detail here. The upper end of the base platform 1 is provided with a support 8, and the upper end of the support 8 is provided with a pressure plate 7. The pressure plate 7 is tilted. After the robotic arm component 6 grasps the workpiece 9 in the positioning area 23, it is first placed on the pressure plate 7 to flatten the workpiece 9. Flattening can prevent the robotic arm component 6 from not grasping the workpiece properly. After flattening, deburring and grinding are performed.

[0044] Specifically, in this embodiment, by setting up a feeding device 2, the workpiece 9 is positioned on the feeding device 2. After the robotic arm component 6 moves to grab the workpiece 9 on the feeding device 2, it moves it to the file component 4 to deburr the positioning hole of the workpiece 9. After deburring, the robotic arm component 6 drives the workpiece 9 to the grinding machine device 5 to grind it. Deburring and grinding are carried out automatically in one piece, which not only saves manpower but also makes the grinding effect better.

[0045] Specifically, in this embodiment, the workpiece 9 is positioned by setting a tray frame 22, and the hole edge cleaning mechanism 3 is set on the feeding frame 21, so that the file 4 is placed near the tray frame 22, which facilitates the deburring of the workpiece 9. By setting multiple positioning points, multiple workpieces 9 can be positioned simultaneously, which can save processing time. By setting positioning pins 24 and inserting them into the positioning holes of the workpiece 9, the workpiece 9 is positioned better, making the positioning position of the workpiece 9 more accurate and preventing cross-movement. By setting a rotating mechanism 25, the rotating mechanism 25 drives the tray frame 22 to rotate, so that each positioning area 23 can move to the gripping position, and each workpiece 9 can move to a fixed position, which is convenient for the robot arm component 6 to grip for subsequent processing. By setting a pressure plate 7, the workpiece 9 can be flattened before grinding, and the workpiece 9 can be gripped better in the subsequent grinding operation.

[0046] As shown in Figures 2 to 4, further, as a preferred embodiment, the grinding device 5 includes a grinding component 51 and a grinding box 52. The grinding box 52 is provided on the base platform 1, and the grinding component 51 is provided inside the grinding box 52. After the robotic arm component 6 grabs the workpiece 9, it is transported to the grinding component 51 to grind the workpiece 9.

[0047] Furthermore, as a preferred embodiment, the polishing assembly 51 includes a first drive mechanism 511 and a first polishing belt 512. The first drive mechanism 511 is provided on one side of the polishing box 52, and the first polishing belt 512 is provided on the first drive mechanism 511 and connected to the first drive mechanism 511.

[0048] Furthermore, as a preferred embodiment, the polishing assembly 51 also includes a second drive mechanism 513 and a second polishing belt 514. The second drive mechanism 513 is provided on the other side of the polishing box 52, and the second polishing belt 514 is provided on the second drive mechanism 513 and connected to the second drive mechanism 513.

[0049] Furthermore, as a preferred embodiment, a collection box 53 is provided below the polishing component 51.

[0050] Specifically, in this embodiment, a collection box 53 is provided at the upper end of the base platform 1. The collection box 53 has an opening at its upper end, and a polishing box 52 is provided on the side of the collection box 53. A polishing component 51 is provided inside the polishing box 52, and the polishing component 51 is located above the opening of the collection box 53. A first drive mechanism 511 and a first polishing belt 512 are provided on the left side of the polishing box 52, and a second drive mechanism 513 and a second polishing belt 514 are provided on the right side of the polishing box 52. A drive motor is provided inside the collection box 53, and the movable end of the drive motor is connected to a main pulley via a main belt.

[0051] Both the first drive mechanism 511 and the second drive mechanism 513 have individual pulleys. The individual pulleys on the rear side of the first drive mechanism 511 and the second drive mechanism 513 are connected to the main pulley via a rotating shaft. A first grinding belt 512 and a second grinding belt 514 are respectively installed on the individual pulleys of the first drive mechanism 511 and the second drive mechanism 513. The rotation of the drive motor drives the main belt transmission, thereby driving the main pulley to rotate, which in turn drives the first drive mechanism 511 and the second drive mechanism 513 to rotate. The first drive mechanism 511 and the second drive mechanism 513 respectively drive the first grinding belt 512 and the second grinding belt 514 for transmission. Both the outer walls of the first grinding belt 512 and the second grinding belt 514 are provided with sandpaper structures.

[0052] The first grinding belt 512 and the second grinding belt 514 are arranged in a straight line perpendicular to the base platform 1 on the side (i.e., the inner side) closest to the robot arm assembly 6, and this side of the first grinding belt 512 and the second grinding belt 514 extends out of the inner opening of the grinding box 52. The length of the collection box 53 is greater than the length of the grinding assembly 51 (i.e., the opening of the collection box 53 extends out of the grinding assembly 51), allowing waste chips generated during the grinding of the workpiece 9 to fall into the collection box 53 through the opening. An electrical box is installed on the base platform 1, and the electrical box is electrically connected to the robot arm assembly 6, the rotary motor, and the drive motor.

[0053] Specifically, in this embodiment, the workpiece 9 is polished by the polishing assembly 51 to make its edge surface smooth. The first driving mechanism 511 drives the first polishing belt 512 to perform a first-stage rough polishing of the workpiece 9. The second driving mechanism 513 drives the second polishing belt 514 to perform further fine polishing of the workpiece 9. The collection box 53 collects the polishing debris, making the worktable cleaner.
