Description

Technical Field

[0001] This invention relates to a multifunctional grinding equipment and grinding method, belonging to the field of grinding equipment. Background Technology

[0002] According to the processing requirements of the workpiece, after processing, the workpiece needs to be processed by cutting tools, polishing machines, vibratory grinders, belt sanders, and other processing equipment. Currently, when processing the workpiece, the corresponding processing equipment needs to be installed separately in the grinding equipment, and it is not possible to integrate cutting tools, polishing machines, vibratory grinders, belt sanders, and other processing equipment into one unit. In view of this, a rotary multi-station belt sander and its working method are disclosed in patent document with application number 202311178179.5. The above-mentioned prior art can only process the workpiece by using a belt sander, but cannot process the workpiece by using cutting tools, polishing machines, or vibratory grinders.

[0003] In view of this, a grinding device and its working method are disclosed in the patent document with application number 202011433521.8. The deburring mechanism C in the above-mentioned prior art is used to deburr the workpiece. The tool is fixedly set on the tool holder fixing seat C2. The tool selection can only be achieved by adjusting the robot's posture. The tool can only move back and forth and cannot rotate, which may result in the workpiece not being ground properly.

[0004] In view of this, a belt sander and its working method are disclosed in patent document application number 202011433529.4, in which the polishing wheel 211 is driven to rotate by the lower grinding rotating shaft 24; a robotic grinding and polishing workstation and its working method are disclosed in patent document application number 202111040641.6, which drives the sanding belt A5 to rotate cyclically on the grinding wheel assembly A2 and the tensioning and correction adjustment assembly A3 through the drive wheel assembly A4, thereby realizing the rotation of the grinding wheel assembly A2. The rotation speed of the polishing wheel in the above-mentioned prior art is limited by the speed of the belt sander and cannot operate independently.

[0005] In view of this, patent document with application number 202310467241.6 discloses a workpiece grinding equipment and grinding method. The aforementioned prior art requires the air grinder to be installed at the end of a robot when grinding a workpiece, and the robot moves the air grinder to the workpiece for grinding. When changing the sandpaper, the robot needs to move the air grinder to the sandpaper changing device B. In view of this, patent document with application number 202311198898 discloses a different method. Patent application document .3 discloses a grinding device and grinding method with detection function. Although the above-mentioned prior art uses a robot to move the workpiece to the grinding machine for grinding when using an air grinder, when changing sandpaper, the positions of the sandpaper sticking mechanism 82 and the sandpaper tearing mechanism 83 are fixed. Therefore, the air grinder needs to swing its arm to the sandpaper sticking mechanism 82 and the sandpaper tearing mechanism 83 to change the sandpaper. Since the position of the air grinder needs to be moved when using the air grinder to grind the workpiece or to change the sandpaper, it will be easily damaged and its service life will be reduced.

[0030] Furthermore, another technical objective of the present invention is to provide a grinding method for a multifunctional grinding device.

[0031] The above-mentioned technical objective of the present invention is achieved through the following technical solution.

[0032] A grinding method for a multifunctional grinding device, characterized in that the grinding method is as follows:

[0033] When the multi-station tool magazine is working, the rotary plate is driven to rotate by the rotary gear motor, which rotates the tool to be used so that it faces the robot. The robot holds the workpiece and places it at the tool to process the workpiece. When the workpiece is being processed by the tool, if the robot's posture cannot reach a certain position of the workpiece, the mounting base can be driven to rotate by the base gear motor, which in turn can realize the rotation of the tool magazine frame, thereby enabling multi-angle processing of the workpiece.

[0034] When the polishing machine is working, the active pulley rotates, which drives the driven pulley to rotate via the transmission belt. This, in turn, drives the polishing wheel to rotate via the polishing shaft. Loosening the adjusting nut and turning the adjusting bolt allows the tensioning shaft to move along the adjusting groove, which in turn allows the tensioning wheel to contact the transmission belt and tighten the transmission belt. After the tension adjustment is completed, tighten the adjusting nut. During the polishing process, if the robot's posture cannot reach a certain position of the workpiece, the mounting base can be rotated by the base reduction motor, which in turn allows the polishing frame to rotate, thus enabling multi-angle processing of the workpiece.

[0035] When the vibratory grinder is working, the robot places the workpiece at the air grinder, which then grinds the workpiece. When the sandpaper on the air grinder needs to be replaced, the robot drives the swing arm to swing the paper-tearing mechanism above the air grinder. The paper-tearing pressure plate is then inserted between the air grinder and the sandpaper attached to it. The paper-tearing pressure plate rotates along the paper-tearing axis, controlled by the paper-tearing clamping cylinder, pressing the sandpaper firmly onto the paper-tearing bracket. Simultaneously, the swing arm moves the paper-tearing bracket via the paper-tearing lifting cylinder, thus removing the sandpaper pressed between the paper-tearing bracket and the paper-tearing pressure plate. The sandpaper is torn off; after the sandpaper is torn off, the drive arm swings, swinging the sandpaper hopper above the air mill. The hopper cylinder controls the hopper body to descend, sticking the bottom sandpaper in the hopper body onto the air mill. The drive arm swings back to the initial position. When the air mill is grinding the workpiece, if a certain position of the workpiece cannot be processed due to the robot's inability to reach it, the mounting base can be rotated by the base reduction motor to adjust the angle of the vibratory mill frame, thereby enabling multi-angle processing of the workpiece.

[0036] When the belt sander is working, the robot places the workpiece on the sanding belt and grinds the workpiece. When the belt sander is grinding the workpiece, if the robot's posture cannot reach a certain position of the workpiece, the mounting base can be rotated by the base reduction motor to adjust the angle of the belt sander, thereby enabling multi-angle processing of the workpiece.

[0037] Compared with the prior art, the present invention has the following advantages: The multi-functional grinding equipment has a modular design of multi-station tool magazine, polishing machine, vibratory grinder, and belt sander. The multi-station tool magazine, polishing machine, vibratory grinder, and belt sander are integrated on the same base. The equipment can perform corresponding processing on the workpiece through the multi-station tool magazine, polishing machine, vibratory grinder, and belt sander, thus realizing multiple functions. The base can be fixed or rotated, which is convenient for cooperation with robots to enable multi-angle processing of workpieces.

[0038] This rotary multi-station tool magazine is used to remove burrs from ground workpieces. The required tool is rotated to the deburring station by rotating the rotating plate. The robot then holds the workpiece to the deburring station to perform the deburring process. When the tool needs to be changed, the rotating plate is driven to rotate, eliminating the need to adjust the robot's posture to move to the positions of multiple tools for corresponding processing. At the same time, if some areas cannot be processed during deburring, the tool magazine frame can be rotated by the mounting base to adjust the position of the tool, thereby achieving multi-angle deburring of the workpiece. The entire multi-station tool magazine can be installed as a module, making it convenient to install in grinding equipment.

[0039] The polishing wheel can be driven independently by the drive pulley, and its speed can be controlled by the polishing drive motor, which is limited by the speed of the belt sander. The modular design makes it easier to install the polishing machine in the grinding equipment. The number of polishing mechanisms can be determined according to actual needs, and multiple polishing mechanisms can be driven by the drive mechanism.

[0040] Whether grinding a workpiece or changing sandpaper, the position of the air grinder remains fixed. During grinding, the robot holds the workpiece and moves it to the air grinder for grinding. When changing sandpaper, the paper tearing mechanism and sandpaper hopper are moved to the air grinder to replace the sandpaper. The fixed position of the air grinder can prevent damage and thus extend its service life. The position of the sandpaper hopper and paper tearing mechanism can be changed by swinging the swing arm. The swing arm is mechanically limited by the limit block when swinging. Attached Figure Description

Figure 18-19 As shown, the tool magazine frame A1 can be installed on the base E via the tool magazine frame side plate A11, the tool magazine frame B1 can be installed on the base E via the polishing frame side plate B11, the vibratory grinder frame C1 can be installed on the base E via the vibratory grinder frame side plate C11, and the belt sander D can be installed on the base E, according to actual needs.

[0094] In this embodiment, the fixed base E includes a fixed base E1, a mounting base E2, and a mounting plate E3. There is at least one mounting plate E3. The vibratory mill frame side plate C11 is mounted on the mounting plate E3. The mounting plate E3 is mounted on the mounting base E2. The mounting base E2 is fixedly mounted on the fixed base E1.

[0095] In this embodiment, the rotating base E includes a fixed base E1, a mounting base E2, a mounting plate E3, and a base reduction motor E4. There is at least one mounting plate E3. The vibratory mill frame side plate C11 is mounted on the mounting plate E3. The mounting plate E3 is mounted on the mounting base E2. The mounting base E2 is rotatably mounted on the fixed base E1.

The fixed base E1 is provided with a cavity for mounting the base reduction motor E4, and the base reduction motor E4 is located inside the cavity.

[0096] The polishing method of the multi-functional polishing equipment in this embodiment is as follows:

[0097] When the multi-station tool magazine A is working, the rotary reduction motor A21 drives the rotating plate A22 to rotate, rotating the tool A3 to be used so that it faces the robot. The robot holds the workpiece and places it at the tool A3 to process the workpiece. When processing the workpiece with the tool A3, if the robot's posture cannot reach a certain position of the workpiece, the base reduction motor E4 drives the mounting base E2 to rotate, thereby realizing the rotation of the tool magazine frame A1. This allows for multi-angle processing of the workpiece.

[0098] When polishing machine B is working, the drive pulley B21 rotates, which drives the driven pulley B22 to rotate via the transmission belt B23. This, in turn, drives the polishing wheel B31 to rotate via the polishing shaft B32. Loosening the adjusting nut B45 and turning the adjusting bolt B44 allows the tensioning shaft B42 to move along the adjusting groove B46, which in turn allows the tensioning wheel B43 to contact the transmission belt B23 and tighten the transmission belt B23. After the tension adjustment is completed, tighten the adjusting nut B45. During the polishing process, if the robot's posture cannot reach a certain position of the workpiece, the mounting base E2 can be rotated via the base reduction motor E4, which in turn allows the polishing frame B1 to rotate, thus enabling multi-angle processing of the workpiece.

[0099] When the vibratory grinder C is working, the robot places the workpiece at the air grinder C3, which then grinds the workpiece. When the sandpaper on the air grinder C3 needs to be replaced, the robot drives the swing arm C2 to swing the paper-tearing mechanism C5 above the air grinder C3, inserting the paper-tearing pressure plate C54 between the air grinder C3 and the sandpaper attached to it. The paper-tearing pressure cylinder C56 controls the paper-tearing pressure plate C54 to rotate along the paper-tearing shaft C55, so that the paper-tearing pressure plate C54 presses the sandpaper onto the paper-tearing bracket C53. While the swing arm C2 is swinging, the paper-tearing lifting cylinder C52 moves the paper-tearing bracket C53, thereby removing the sandpaper pressed onto the paper-tearing bracket C53. 3. Tear off the sandpaper between the paper tearing plate C54 and the paper tearing plate C54; after the sandpaper is torn off, drive the swing arm C2 to swing the sandpaper hopper C4 above the air mill C3. The hopper cylinder C42 controls the hopper body C43 to descend, and sticks the bottom sandpaper in the hopper body C43 onto the air mill C3. Drive the swing arm C2 back to the initial position; when the air mill C3 is grinding the workpiece, if a certain position of the workpiece cannot be processed due to the robot's posture, the mounting base E2 can be rotated by the base reduction motor E4 to adjust the angle of the vibratory mill frame C1, thereby enabling multi-angle processing of the workpiece.

[0100] When the belt sander D is working, the robot places the workpiece on the sanding belt and grinds the workpiece. When the belt sander D is grinding the workpiece, if the robot's posture cannot reach a certain position of the workpiece, the mounting base E2 can be rotated by the base reduction motor E4 to adjust the angle of the belt sander D, thereby enabling multi-angle processing of the workpiece.
