Description

Technical Field

[0001] This utility model belongs to the field of sheet metal processing, specifically a sheet metal grinding machine. Background Technology

[0002] Sheet metal technology is currently widely used in many fields such as automobile manufacturing, aerospace, electronics and electrical appliances, and machinery and equipment manufacturing. Sheet metal technology not only improves the precision and surface quality of processed parts, but also improves production efficiency and product quality.

[0003] Existing sheet metal grinding equipment typically requires placing the workpiece inside the machine and turning on the grinding equipment during sheet metal operations. The grinding discs generate friction to perform sheet metal grinding work. However, multiple grinding discs or grinding pads cannot work simultaneously during grinding, which affects production efficiency.

[0004] Therefore, this utility model provides a sheet metal grinding machine. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The sheet metal grinding machine of this utility model includes a fine grinding belt, a triangular shaft installed inside the fine grinding belt, and the inner wall of the fine grinding belt wrapped around the upper surface of the triangular shaft; a rotating shaft is fixedly connected to the side of the triangular shaft, a first motor is fixedly connected to the side of the rotating shaft, a baffle is fixedly connected to the upper surface of the rotating shaft, and the first motor is sleeved inside the rotating shaft; a bracket is fixedly connected to the inner side of the baffle, a grinding frame is fixedly connected to the side of the bracket, a second motor is fixedly connected to the top of the grinding frame, and a coarse grinding disc is fixedly connected to the top of the second motor. With the setup of a coarse grinding disc and a second motor, the high-speed rotating coarse grinding disc quickly performs preliminary rough grinding on the surface of sheet metal items, making the surface unevenness more uniform. The grinding frame and support provide a stable working state for the coarse grinding disc. At the same time, the setup of the first motor allows the triangular shaft and fine grinding belt to operate at a slower grinding speed. The triangularly distributed shafts more smoothly drive the rotation of the fine grinding belt, enabling the fine grinding belt to perform fine grinding on the surface of the sheet metal items. The roughing work of the coarse grinding disc combined with the fine grinding work of the fine grinding belt allows the entire workflow to proceed simultaneously, improving processing efficiency and grinding quality.

[0007] Preferably, a conveyor shaft is fixedly connected to the inner side of the baffle, a conveyor chain is rotatably connected to the upper surface of the suction cup, a suction cup is fixedly connected to the upper surface of the conveyor chain, a third motor is rotatably connected to the side of the conveyor shaft, and the third motor is located outside the baffle and fixedly connected to the baffle; a metal leg is fixedly connected to the bottom of the baffle, a round foot is fixedly connected to the bottom of the metal leg, and a connecting rod is fixedly connected to the inner wall of the baffle. The evenly arranged arrangement of multiple suction cups allows items to be firmly adhered to the machine, preventing displacement during sheet metal grinding and avoiding safety hazards; the metal legs and round feet ensure the machine firmly grips the ground, and the connecting rod provides lateral pulling force, ensuring stable operation; the multiple grooves on the outer surface of the conveyor shaft allow for more flexible selection and loading of the conveyor chain, enabling the machine to grind parts of different sizes and increasing its application range.

[0008] Preferably, a small base is fixed to the inner wall of the baffle, and the small bases are evenly distributed. A first hydraulic rod is fixed to the side of the small base, and an arm support is fixed to the side of the first hydraulic rod. Arm shafts are fixed to both ends of the arm support, and a swing arm is hinged to the outer surface of the arm shaft. A fourth motor is fixed to the outer surface of the swing arm, and a side grinding ring is fixed to the output end of the fourth motor. The output end of the fourth motor is fitted into and passes through the inside of the swing arm. By setting up the side grinding ring, the edges of the item requiring sheet metal work can be ground simultaneously, improving work efficiency. The small bases allow for flexible control of the grinding position of the side grinding ring, increasing the machine's grinding range. The adjustable tension of the swing arm also increases the machine's grinding range.

[0009] Preferably, a dust cover is fixed to the top of the baffle, and multiple dustproof strips are fixed to the sides of the dust cover in a uniform distribution. The combined arrangement of the dust cover and dustproof strips prevents metal debris from splashing in four directions simultaneously, improving operator safety and protecting the hygiene of the working environment.

[0010] Preferably, a second hydraulic rod is fixedly connected to the inner wall of the dust cover, and a stabilizing disc is fixedly connected to the bottom of the second hydraulic rod. The stabilizing disc increases friction not only through the weight of the workpiece during sheet metal work, but also through the pressure of the stabilizing disc, thereby increasing the friction between the sheet metal workpiece and the grinding disc, further improving machine efficiency.

[0011] Preferably, a dust box is installed directly below the baffle, and a magnet is fixed to the inner surface of the dust box. When metal fragments fly and fall, the dust box can catch them. At this time, the magnet inside the dust box can attract the fragments, preventing the fragments from spreading and polluting the working environment. The combination of the dust box and the magnet can further improve the working environment around the machine and enhance the safety of the staff.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The sheet metal grinding machine of this utility model, through the setting of a coarse grinding disc and a second motor, allows the high-speed rotating coarse grinding disc to quickly and roughly grind the surface of the sheet metal, making the surface unevenness more uniform. The grinding frame and support provide a stable working state for the coarse grinding disc. At the same time, the setting of the first motor allows the triangular shaft and the fine grinding belt to be in a slow grinding state. The triangularly distributed triangular shaft drives the rotation of the fine grinding belt more smoothly, allowing the fine grinding belt to finely grind the surface of the sheet metal. The coarse grinding of the coarse grinding disc and the fine grinding of the fine grinding belt allow the entire process to be carried out simultaneously, improving processing efficiency and grinding quality.

[0014] 2. The sheet metal grinding machine of this utility model, through the evenly arranged arrangement of multiple suction cups, can firmly adhere the object to the machine, preventing it from shifting during sheet metal grinding and causing safety hazards; the metal legs and round feet allow the machine to firmly grip the ground, and the connecting rod provides lateral pulling force to the machine, making it run smoothly; the multiple grooves on the outer surface of the conveyor shaft make the conveyor chain more flexible in picking and selecting, allowing the machine to grind parts of different sizes and increasing its range of applications.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1 to 3As shown in the embodiment of this utility model, a sheet metal grinding machine includes a fine grinding belt 1, a triangular shaft 11 installed inside the fine grinding belt 1, and the inner wall of the fine grinding belt 1 wound around the upper surface of the triangular shaft 11; a rotating shaft 18 is fixedly connected to the side of the triangular shaft 11, a first motor 12 is fixedly connected to the side of the rotating shaft 18, a baffle 13 is fixedly connected to the upper surface of the rotating shaft 18, and the first motor 12 is sleeved inside the rotating shaft 18; a bracket 14 is fixedly connected to the inner side of the baffle 13, a grinding frame 15 is fixedly connected to the side of the bracket 14, a second motor 16 is fixedly connected to the top of the grinding frame 15, and a coarse grinding disc 17 is fixedly connected to the top of the second motor 16. During operation, when the item requiring sheet metal work reaches directly above the coarse grinding disc 17, the operator starts the second motor 16. At this time, the second motor 16 drives the coarse grinding disc 17 to rotate and begin sheet metal grinding. The three coarse grinding discs 17 are arranged in a triangle, with their upper surfaces horizontal, allowing for grinding of the item. The support 14 and grinding frame 15 provide stable support for the second motor 16, and the baffle 13 provides stable support for the support 14. After the second motor 16 has been running at high speed for a period of time, the machine is moved directly above the fine grinding belt 1. At this time, the operator starts the first motor 12, which drives the rotating shaft 18 to rotate. The rotating shaft 18 drives the triangular shaft 11 and the fine grinding belt 1 to rotate. The triangular shaft 11 is arranged in a vertical triangle, allowing for sheet metal grinding of the item. With the coarse grinding disc 17 and the second motor 16, the high-speed rotating coarse grinding disc 17 quickly performs preliminary rough grinding on the surface of the sheet metal item, making the surface unevenness more uniform. The grinding frame 15 and the support 14 provide a stable working state for the coarse grinding disc 17. At the same time, with the first motor 12, the triangular shaft 11 and the fine grinding belt 1 can be in a slow grinding state. The triangularly distributed triangular shaft 11 drives the rotation of the fine grinding belt 1 more smoothly, allowing the fine grinding belt 1 to perform fine grinding on the surface of the sheet metal item. The coarse grinding of the coarse grinding disc 17 and the fine grinding of the fine grinding belt 1 make the entire process work simultaneously, improving processing efficiency and grinding quality.

[0027] like Figure 4As shown, a conveyor shaft 22 is fixedly connected to the inner side of the baffle 13, a conveyor chain 21 is rotatably connected to the upper surface of the suction cup 2, a suction cup 2 is fixedly connected to the upper surface of the conveyor chain 21, a third motor 23 is rotatably connected to the side of the conveyor shaft 22, the third motor 23 is on the outer side of the baffle 13 and fixedly connected to the baffle 13; a metal leg 24 is fixedly connected to the bottom of the baffle 13, a round foot 25 is fixedly connected to the bottom of the metal leg 24, and a connecting rod 26 is fixedly connected to the inner wall of the baffle 13. Before starting the machine, select the installation position of the conveyor chain 21 on the conveyor shaft 22 according to the size of the sheet metal parts to be ground. The closer to the inside, the smaller the parts to be ground. Then, start the machine to make the third motor 23 rotate. The third motor 23 drives the conveyor shaft 22 and the conveyor chain 21 to rotate. Place the items to be ground horizontally on the upper surface of the suction cup 2. Due to the downward force of the object's own gravity, the multiple suction cups 2 will firmly adhere to the object at both ends and bring the object to the designated position. Then, stop the third motor 23 and start the internal sheet metal grinding work. After the grinding is completed, the third motor 23 can be started again to take the item away from the machine and then carry out the next round of transportation work. The evenly arranged suction cups 2 can firmly adhere items to the machine, preventing them from shifting during sheet metal grinding and causing safety hazards. The metal legs 24 and round feet 25 allow the machine to firmly grip the ground, while the connecting rod 26 provides lateral pulling force to ensure smooth operation. The multiple grooves on the outer surface of the conveyor shaft 22 make the conveyor chain 21 more flexible in selecting and loading parts, allowing the machine to grind parts of different sizes and increasing its application range.

[0028] like Figure 5As shown, a small base 36 is fixed to the inner wall of the baffle 13. The small bases 36 are evenly distributed. A first hydraulic rod 35 is fixed to the side of the small base 36. An arm support 34 is fixed to the side of the first hydraulic rod 35. An arm shaft 33 is fixed to both ends of the arm support 34. A swing arm 32 is hinged to the outer surface of the arm shaft 33. A fourth motor 31 is fixed to the outer surface of the swing arm 32. A side grinding ring 3 is fixed to the output end of the fourth motor 31. The output end of the fourth motor 31 is fitted into and passes through the inside of the swing arm 32. During operation, the first hydraulic rod 35 is fixed to the small base 36, which can extend and retract freely as needed to send the arm support 34 to the designated position. When the item to be polished is small, the first hydraulic rod 35 is extended, and vice versa for smaller items. At this time, the bottom of the swing arm 32 is fitted onto the arm shaft 33. The operator can control the opening and closing of the swing arm 32, and thus control the opening and closing of the side polishing ring 3. When the side polishing ring 3 clamps the side of the item to be sheet metalned, the fourth motor 31 is turned on, and the side polishing ring 3 begins to rotate to polish the edge of the item. At this time, the third motor 23 is controlled to rotate left and right, driving the item to move left and right. Multiple evenly arranged side polishing rings 3 will polish the side of the item simultaneously. By setting the side grinding ring 3, the edges of the items that need sheet metal work can be ground at the same time while grinding the upper surface of the items. This improves work efficiency. The small base 36 allows for flexible control of the grinding position of the side grinding ring 3, increasing the grinding range of the machine. The adjustable clamping mechanism of the swing arm 32 also increases the grinding range of the machine.

[0029] like Figures 6 to 7 As shown, a dust cover 4 is fixedly attached to the top of the baffle 13, and multiple dustproof strips 41 are fixedly attached to the sides of the dust cover 4 and are evenly distributed. During operation, when grinding is carried out inside the dust cover 4, metal shavings will be generated and fly everywhere. At this time, the dust cover 4 remains fixed to the baffle 13 and catches the metal shavings. The dustproof strips 41 do not obstruct the entry and exit of sheet metal items, but at the same time block the metal shavings. Through the coordinated arrangement of the dust cover 4 and the dustproof strips 41, the flying of metal shavings is prevented from four directions simultaneously, improving the safety of operators and protecting the hygiene of the working environment.

[0030] like Figures 6 to 7As shown, a second hydraulic rod 51 is fixedly connected to the inner wall of the dust cover 4, and a stabilizing plate 5 is fixedly connected to the bottom of the second hydraulic rod 51. During operation, when the conveyor chain 21 transports the sheet metal workpiece to directly above the fine grinding belt 1 or the coarse grinding disc 17, before the fine grinding belt 1 or the coarse grinding disc 17 starts working, the machine is operated to lower the second hydraulic rod 51. At this time, the stabilizing plate 5 will also lower, and the second hydraulic rod 51 will press down slightly against the sheet metal workpiece before the sheet metal grinding work is started. By setting the stabilizing plate 5, the friction between the sheet metal workpiece and the grinding disc is increased not only by its own weight, but also by the pressure of the stabilizing plate 5, thus further improving the machine's working efficiency.

[0031] like Figure 8 As shown, a dust box 6 is installed directly below the baffle 13, and a magnet 61 is fixed to the inner surface of the dust box 6. During operation, the dust box 6 is located directly below the fine grinding belt 1 and the coarse grinding disc 17. When metal shavings fly and fall, the dust box 6 can catch them. At this time, the magnet 61 inside the dust box 6 can attract the shavings, preventing the shavings from spreading and polluting the working environment. Through the combined arrangement of the dust box 6 and the magnet 61, the working environment around the machine can be further improved, and the safety of the workers can also be enhanced.

[0032] Working principle: When the item to be metallurgically processed reaches directly above the coarse grinding disc 17, the machine starts the second motor 16. At this time, the second motor 16 drives the coarse grinding disc 17 to rotate and begin metallurgical grinding. The three coarse grinding discs 17 are arranged in a triangle, with their upper surfaces horizontal, allowing for grinding of the item. The support 14 and grinding frame 15 provide stable support for the second motor 16, and the baffle 13 provides stable support for the support 14. After the second motor 16 runs at high speed for a period of time, it moves the machine directly above the fine grinding belt 1. At this time, the machine starts the first motor 12, which drives the rotating shaft 18 to rotate. The rotating shaft 18 drives the triangular shaft 11 and the fine grinding belt 1 to rotate. The triangular shaft 11 is arranged in a vertical triangle, allowing for metallurgical grinding of the item.

[0033] Before starting the machine, select the installation position of the conveyor chain 21 on the conveyor shaft 22 according to the size of the sheet metal parts to be ground. The closer to the inside, the smaller the parts to be ground. Then, start the machine to make the third motor 23 rotate. The third motor 23 drives the conveyor shaft 22 and the conveyor chain 21 to rotate. Place the items to be ground horizontally on the upper surface of the suction cup 2. Due to the downward force of the object's own gravity, the multiple suction cups 2 will firmly adhere to the object at both ends and bring the object to the designated position. Then, stop the third motor 23 and start the internal sheet metal grinding work. After the grinding is completed, the third motor 23 can be started again to take the item away from the machine and then carry out the next round of transportation work.

[0034] During operation, the first hydraulic rod 35 is fixed to the small base 36, which can extend and retract freely as needed to send the arm support 34 to the designated position. When the item to be polished is small, the first hydraulic rod 35 is extended, and vice versa for smaller items. At this time, the bottom of the swing arm 32 is fitted onto the arm shaft 33. The operator can control the opening and closing of the swing arm 32, and thus control the opening and closing of the side polishing ring 3. When the side polishing ring 3 clamps the side of the item to be sheet metalned, the fourth motor 31 is turned on, and the side polishing ring 3 begins to rotate to polish the edge of the item. At this time, the third motor 23 is controlled to rotate left and right, driving the item to move left and right. Multiple evenly arranged side polishing rings 3 will polish the side of the item simultaneously.

[0035] When grinding is carried out inside the dust cover 4, metal shavings will be generated and fly everywhere. At this time, the dust cover 4 is fixed to the baffle 13 and remains stationary to catch the metal shavings. The dust belt 41 will not block sheet metal items when they enter or exit, but will block metal shavings.

[0036] During operation, when the conveyor chain 21 transports the sheet metal item to the top of the fine grinding belt 1 or the coarse grinding disc 17, before the fine grinding belt 1 or the coarse grinding disc 17 starts working, the machine is operated to lower the second hydraulic rod 51. At this time, the stabilizing disc 5 will also lower, and the second hydraulic rod 51 will be in close contact with the sheet metal item and press down slightly before the sheet metal grinding work is started.

[0037] During operation, the dust box 6 is located directly below the fine grinding belt 1 and the coarse grinding disc 17. When metal shavings fly and fall, the dust box 6 can catch them. At this time, the magnet 61 inside the dust box 6 can attract the shavings and prevent the shavings from spreading and polluting the working environment.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
