Description

Technical Field

[0001] This application relates to the field of grinding and processing devices, and more particularly, to a grinding device. Background Art

[0002] A commercial vehicle overhead box door panel is installed on the overhead box body and has requirements for gaps and surface differences, which places high demands on the shape of the back of the door panel. Since the water jet cannot cut horizontally after the mold is formed, there will still be an ineffective edge of 2-3 mm left after water jet cutting. At present, after rough cutting with a water jet, the four sides are manually polished. Or for some other automotive components that require high-precision grinding, manual grinding is generally used at present.

[0003] However, manual grinding has the following disadvantages: (1) The manual grinding rhythm is slow, increasing the cost of the product; (2) The consistency of manual grinding is poor, and human factors are significant; (3) More dust is generated during grinding, causing a certain health hazard to personnel. Summary of the Utility Model

[0004] The purpose of this application is to provide a grinding device to improve the technical problems of slow manual grinding efficiency, poor consistency, and the health hazard of dust to personnel.

[0005] In a first aspect, an embodiment of this application provides a grinding device, including a loading platform, a grinding assembly, and a fence. The loading platform has a loading station and a processing station. A plurality of loading parts for fixing workpieces are arranged on the top of the loading platform. The loading platform is used for rotation so that each loading part can be switched between the loading station and the processing station; the grinding assembly is used for grinding the workpiece fixed on the loading part at the processing station; the fence surrounds and shields the grinding assembly and the processing station.

[0006] In the above implementation process, this application sets a loading platform and a grinding assembly. The loading platform has a loading station and a processing station. The loading platform rotates to switch each loading part between the loading station and the processing station. When a loading part rotates with the loading platform to the processing station, other loading parts are at the loading station. Workpieces can be fixed on the loading parts at the loading station at the same time, and the grinding assembly grinds the workpiece fixed on the loading part at the processing station; after grinding is completed, the loading platform rotates to switch the ground workpiece fixed on the loading part at the processing station to the loading station, and the ground workpiece can be removed. The workpiece fixed on the loading part at the loading station is switched to the processing station for grinding, so as to perform continuous loading, grinding, and unloading, with relatively high grinding efficiency; and the workpiece is positioned by the loading part and ground by the grinding assembly, with relatively high grinding consistency; at the same time, the grinding assembly and the processing station are surrounded and shielded by the fence, and the dust can be enclosed within the fence during grinding, preventing the dust from spreading outside and causing harm to the health of personnel.

[0007] In a possible implementation, a fence located between the feeding station and the processing station is provided with a passage for the load-carrying part to pass through, and a closing plate is arranged at the passage for selectively closing the passage.

[0008] In this application, a passage is provided in the fence between the feeding station and the processing station. When the load platform rotates to switch the load-carrying part between the feeding station and the processing station, the passage is opened so that the load-carrying part can pass through the passage to switch positions. When grinding is performed, the closing plate closes the passage to make the entire fence closed, so as to seal and isolate the dust generated during grinding.

[0009] In a possible implementation, a driving member is connected to the closing plate, and the driving member is used to drive the closing plate to move so as to open or close the passage.

[0010] In this application, the driving member drives the closing plate to move, thereby opening or closing the passage, which is convenient for control.

[0011] In a possible implementation, an electromagnetic valve is arranged between the closing plate and the fence to make the closing plate tightly close the passage.

[0012] In this application, by arranging an electromagnetic valve between the closing plate and the fence, when the closing plate closes the passage, the closing plate and the fence are tightly closed through the electromagnetic valve, so that the closing plate tightly closes the passage, avoiding dust flying out of the fence due to loosening of the closing plate during grinding.

[0013] In a possible implementation, the load-carrying part includes a fixing plate fixed to the load platform, and a load-carrying jig for fixing the workpiece is connected to the fixing plate.

[0014] In this application, by setting the load-carrying jig, the workpiece can be conveniently fixed to efficiently grind the workpiece.

[0015] In a possible implementation, positioning posts are arranged on the fixing plate, and mounting holes are formed in a side wall of the load-carrying jig close to the fixing plate, and the mounting holes are detachably inserted outside the positioning posts.

[0016] In this application, by arranging positioning posts on the fixing plate, the load-carrying jig is detachably connected to the positioning posts through the mounting holes, which is convenient for replacing the load-carrying jig. When grinding workpieces of different models, different models of corresponding load-carrying jigs are used to fix the workpieces. At the same time, when the load-carrying jig is connected to the positioning posts through the mounting holes, the positioning posts can quickly position the load-carrying jig, so that the fixing position of the load-carrying jig is kept consistent each time, which is beneficial to the consistency of subsequent grinding.

[0017] In a possible implementation, the load-carrying tool includes a load-carrying plate. A cavity is recessed in a side wall of the load-carrying plate away from the fixing plate. A sealing strip is disposed around the peripheral wall of the cavity. An exhaust pipe is connected to the bottom wall of the cavity to communicate the exhaust pipe with the cavity. The exhaust pipe is connected to a vacuum pump to evacuate the cavity, so that the workpiece is hermetically connected to the sealing strip.

[0018] In this application, by recessing a cavity in the load-carrying plate and disposing a sealing strip around the peripheral wall of the cavity, when the workpiece is placed on the load-carrying plate, the workpiece contacts the sealing strip to close the cavity. At this time, the cavity is evacuated to tightly connect and fix the workpiece to the load-carrying plate. The operation is convenient and can avoid damaging the workpiece.

[0019] In a possible implementation, a support frame is fixedly connected between the load-carrying plate and the fixing plate. One side of the positioning column away from the fixing plate is connected to the load-carrying plate. The height of the support frame is adapted to the height of the positioning column.

[0020] In this application, by fixedly connecting a support frame between the load-carrying plate and the fixing plate, a certain support strength can be provided for the load-carrying plate, which is beneficial to subsequent grinding of the workpiece fixed on the load-carrying plate.

[0021] In a possible implementation, the load-carrying platform is of a circular structure. The load-carrying platform is provided with three load-carrying parts, and the three load-carrying parts are arranged at equal intervals along the circumferential direction of the load-carrying platform.

[0022] In this application, by setting the load-carrying platform as a circular structure, it is beneficial to the rotation of the load-carrying platform. At the same time, by arranging three load-carrying parts at equal intervals along the circumferential direction on the load-carrying platform, feeding, grinding, and discharging can be carried out conveniently and efficiently.

[0023] In a possible implementation, the grinding assembly includes a manipulator, and a milling cutter is clamped at the working end of the manipulator.

[0024] In this application, the milling cutter is controlled by the manipulator for grinding, and the grinding has good consistency, high precision, and good grinding quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Embodiment

[0036] At present, for some automotive interior door panels and components with high styling requirements, they are generally rough-cut first and then finely polished manually. However, manual polishing is inefficient, and due to human factors, inconsistencies are likely to occur. At the same time, the dust generated during polishing is likely to cause health damage to personnel.

[0037] The present application aims to improve the technical problems of slow efficiency, poor consistency, and the health hazards caused by dust to personnel in the existing manual polishing, and proposes a polishing device, as Figure 1 shown, including a loading platform 1, a polishing assembly 2, and a fence 3. The loading platform 1 has a loading station and a processing station. A plurality of loading parts for fixing workpieces are arranged on the top of the loading platform 1. The loading platform 1 is used for rotation so that each loading part can be switched between the loading station and the processing station; the polishing assembly 2 is used for polishing the workpiece fixed on the loading part at the processing station; the fence 3 surrounds and shields the polishing assembly 2 and the processing station.

[0038] It should be noted that: the loading station and the processing station on the loading platform 1 are virtual stations, that is, a part of the area where the loading platform 1 is located is defined as the loading station, and a part of the area where the loading platform 1 is located is defined as the processing station. The loading station is mainly for installing or disassembling the workpiece on the loading part, and the processing station is mainly for polishing the workpiece on the loading part. When the loading platform 1 rotates, the loading station and the processing station do not change, but only the position of the loading part on the loading platform 1 changes, so that the position of the loading part can be rotated and switched from the loading station to the processing station, or from the processing station to the loading station.

[0039] By setting the loading platform 1 and the grinding component 2, the loading platform 1 has a feeding station and a processing station. The loading platform 1 rotates to switch each loading part between the feeding station and the processing station. When a loading part rotates with the loading platform 1 to the processing station, the other loading parts are located at the feeding station. Workpieces can be fixed on the loading parts at the feeding station at the same time, and the grinding component 2 grinds the workpieces fixed on the loading part at the processing station; after grinding, the loading platform 1 rotates to switch the ground workpieces fixed on the loading part at the processing station to the feeding station, and the ground workpieces can be taken off. The workpieces fixed on the loading part at the feeding station are switched to the processing station for grinding, so as to continuously feed, grind, and unload materials, and the grinding efficiency is relatively high; and the workpieces are positioned by the loading parts and the grinding component 2 performs grinding, so the grinding consistency is relatively high; at the same time, the grinding component 2 and the processing station are enclosed and blocked by the fence 3, and the dust can be enclosed within the fence 3 during grinding, avoiding the harm to human health caused by the dust floating outside.

[0040] In some embodiments, the fence 3 located between the feeding station and the processing station is provided with a passage 31 for the loading part to pass through, and a closing plate 32 is arranged at the passage 31. The closing plate 32 is used to selectively close the passage 31. When the loading platform 1 rotates to switch the loading part between the feeding station and the processing station, the passage 31 is opened so that the loading part can pass through the passage 31 to switch positions. When grinding is carried out, the closing plate 32 closes the passage 31 so that the entire fence 3 is closed to isolate and seal the dust generated during grinding.

[0041] Exemplarily, only one passage 31 is provided in the fence 3 between the processing station and the adjacent feeding stations on its left and right, and the loading parts on the adjacent feeding stations on the left and right of the processing station can both pass through the passage 31. Alternatively, one passage 31 is provided in the fence 3 between the processing station and the adjacent feeding station on its left, and one passage 31 is also provided in the fence 3 between the processing station and the adjacent feeding station on its right. One passage 31 is for one loading part to pass through. By respectively providing two passages 31, the width of each passage 31 can be set narrower, and then the closing plate 32 can be correspondingly set narrower, which is convenient for controlling the opening and closing.

[0042] In some embodiments, a driving member 33 is connected to the closing plate 32. The driving member 33 is used to drive the closing plate 32 to move so as to open or close the passage 31. The driving member 33 drives the closing plate 32 to move, thereby opening or closing the passage 31, which is convenient for control.

[0043] Exemplarily, the driving member 33 can be but is not limited to a cylinder or an electric push rod. The driving member 33 is electrically connected to the PLC, and the PLC is used to control the driving member 33 to drive the closing plate 32 to move.

[0044] In some embodiments, a solenoid valve is provided between the closing plate 32 and the fence 3 to tightly seal the closing plate 32 to the passage 31. When the closing plate 32 seals the passage 31, the closing plate 32 and the fence 3 are tightly closed through the solenoid valve, so that the closing plate 32 tightly seals the passage 31, preventing dust from flying out of the fence 3 due to the loosening of the closing plate 32 during grinding.

[0045] Exemplarily, the solenoid valve is electrically connected to the PLC, and the opening and closing of the solenoid valve are controlled by the PLC. When the passage 31 needs to be opened, the solenoid valve is controlled to open, and then the closing plate 32 is controlled to move to open the passage 31; when the passage 31 needs to be closed, the closing plate 32 is controlled to move to close the passage 31, and then the solenoid valve is controlled to close, so that the closing plate 32 can no longer move and tightly seals the passage 31.

[0046] In some embodiments, the loading part includes a fixing plate 11 fixed to the loading platform 1, and a loading jig 12 for fixing the workpiece is connected to the fixing plate 11. The loading jig 12 can conveniently fix the workpiece for efficient grinding of the workpiece.

[0047] Exemplarily, the model of the loading jig 12 is adapted to the model of the workpiece it fixes, and the appropriate loading jig 12 can be selected according to the workpiece to be ground actually.

[0048] In some embodiments, positioning posts are provided on the fixing plate 11, and mounting holes are formed in a side wall of the loading jig 12 close to the fixing plate 11. The mounting holes are detachably inserted outside the positioning posts. The loading jig 12 is detachably connected to the positioning posts through the mounting holes, facilitating the replacement of the loading jig 12. When grinding workpieces of different models, different models of workpieces are fixed by corresponding loading jigs 12 of different models; at the same time, when the loading jig 12 is connected to the positioning posts through the mounting holes, the positioning posts can quickly position the loading jig 12, making the fixing position of the loading jig 12 consistent each time, which is beneficial to the consistency of subsequent grinding.

[0049] Exemplarily, two positioning posts are symmetrically arranged on the fixing plate 11. Four or six positioning posts can also be symmetrically arranged. The number of positioning posts can be set according to actual needs.

[0050] In some embodiments, the load-carrying tool 12 includes a load-carrying plate 121. A cavity 122 is recessed in a side wall of the load-carrying plate 121 away from the fixed plate 11. A sealing strip 123 is disposed around the peripheral wall of the cavity 122. An exhaust pipe is connected to the bottom wall of the cavity 122 to communicate the exhaust pipe with the cavity 122. The exhaust pipe is connected to a vacuum pump to evacuate the cavity 122, so that the workpiece is hermetically connected to the sealing strip 123. When the workpiece is placed on the load-carrying plate 121, the workpiece contacts the sealing strip 123 to close the cavity 122. At this time, the cavity 122 is evacuated, so that the workpiece is tightly connected and fixed on the load-carrying plate 121. The operation is convenient, and damage to the workpiece can be avoided.

[0051] In some embodiments, a support frame 13 is fixedly connected between the load-carrying plate 121 and the fixed plate 11. One side of the positioning post away from the fixed plate 11 is connected to the load-carrying plate 121. The height of the support frame 13 is adapted to the height of the positioning post. The support frame 13 can provide a certain support strength for the load-carrying plate 121, which is beneficial to subsequent grinding of the workpiece fixed on the load-carrying plate 121.

[0052] In some embodiments, the load-carrying platform 1 is of a circular structure. The load-carrying platform 1 is provided with three load-carrying parts, and the three load-carrying parts are arranged at equal intervals along the circumferential direction of the load-carrying platform 1. Setting the load-carrying platform 1 as a circular structure is beneficial to the rotation of the load-carrying platform 1. At the same time, arranging three load-carrying parts at equal intervals along the circumferential direction of the load-carrying platform 1 can facilitate and efficiently perform loading, grinding, and unloading.

[0053] In some embodiments, the grinding assembly 2 includes a manipulator 21, and a milling cutter 22 is clamped at the working end of the manipulator 21. The milling cutter 22 is controlled by the manipulator 21 for grinding. The grinding has good consistency, high precision, and good grinding quality.

[0054] Exemplarily, the manipulator 21 adopts an offline programming method, which can better conform to the theoretical data.

[0055] During operation, first fix the workpiece to be polished on the matching carrier plate 121, and then connect the carrier plate 121 with the workpiece fixed thereon to the positioning post 111 on the fixed plate 11 at the loading station to fix the position of the carrier plate 121. Open the solenoid valve and control the driving member 33 to drive the closing plate 32 to move upward to open the passage 31 on the fence 3 between the loading station and the processing station. Then rotate the loading platform 1 to rotate and switch the loading station with the workpiece fixed thereon to the processing station. Then control the driving member 33 to drive the closing plate 32 to move downward, close the solenoid valve, and make the closing plate 32 tightly seal the passage 31 to seal the fence 3. Start the polishing assembly 2 to polish the fixed workpiece at the processing station; while polishing, the next workpiece to be polished can be fixed at the loading station outside the fence 3; after polishing, open the solenoid valve, control the driving member 33 to drive the closing plate 32 to move upward to open the passage 31 on the fence 3 between the loading station and the processing station again. Then rotate the loading platform 1 to switch between the loading station and the processing station. Then control the driving member 33 to drive the closing plate 32 to move downward, close the solenoid valve, and make the closing plate 32 tightly seal the passage 31 again to seal the fence 3. Start the polishing assembly 2 to polish the next workpiece at the processing station; the polished workpiece fixed at the loading station can be removed and stored; in this way, continuous feeding, polishing, and discharging can be cycled to perform polishing efficiently; and the workpiece is fixed by the carrier plate 121 and the carrier plate 121 is positioned by the positioning post 111, and the polishing assembly 2 performs polishing, so the polishing is more accurate and has higher consistency; at the same time, the polishing assembly 2 and the processing station are enclosed and sealed by the fence 3, and the dust can be enclosed within the fence 3 during polishing to avoid harm to the health of personnel caused by the dispersion of dust outside.

[0056] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application.
