They are widely used in electronics, electrical engineering, communications, automation control, transportation, aerospace, and military fields.

[0003] In existing technologies, during the processing of metal boxes, a robotic arm is needed to operate a grinding device to perform flexible grinding on the weld seams of the metal box. Although the robotic arm can operate the grinding device to perform relatively comprehensive grinding on the metal box, the bottom of the metal box cannot be ground. The worker needs to flip the box so that the robotic arm can operate the grinding device to grind the bottom of the metal box. This process is time-consuming and labor-intensive, which reduces the efficiency of flexible grinding of metal boxes. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology where, during the processing of metal boxes, a robotic arm is needed to operate a grinding device to perform flexible grinding on the weld seams of the metal box. Although the robotic arm can operate the grinding device to perform relatively comprehensive grinding on the metal box, the bottom of the metal box cannot be ground. The box needs to be flipped over by the worker so that the robotic arm can operate the grinding device to grind the bottom of the metal box. This process is time-consuming and labor-intensive, resulting in a decrease in the efficiency of flexible grinding of metal boxes.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a flexible grinding device for weld seams of metal boxes, comprising: a worktable, a robotic arm fixedly connected to one side of the worktable, a grinder provided at one end of the robotic arm, and further comprising:

[0006] Multiple fixed plates are fixedly connected to the top of the workbench. A movable rod 2 is movably connected to one side of each fixed plate near the top. A clamping plate is fixedly connected to one end of the movable rod 2. Connecting plates are provided around the workbench. The movable rod 2 is rotatably connected to the connecting plates. Two fixed blocks are symmetrically fixedly connected to one side of each of the two connecting plates. A worm gear is rotatably connected to the opposite side of each of the two fixed blocks. A motor 2 is fixedly connected to one side of each of the two fixed blocks. The output end of the motor 2 is fixedly connected to one end of the worm gear. A worm wheel is fixedly connected to one end of each of the two movable rod 2. The worm wheel is threadedly connected to the worm gear.

[0007] Preferably, a support frame is fixedly connected to the bottom of the workbench, and a rotating shaft is rotatably connected to the center of the bottom of the support frame. A disc is fixedly connected to one end of the rotating shaft, and a motor is fixedly connected to the bottom of the support frame. The output end of the motor is fixedly connected to the other end of the rotating shaft.

[0008] Preferably, the top of the disk is symmetrically and fixedly connected with multiple round rods one in pairs, and the outer surface of the round rods one is rotatably connected with a movable strip, and the top of the movable strip away from the round rods one is fixedly connected with round rods two.

[0009] Preferably, each of the four support arms of the support frame is slidably connected to a movable rod, the movable rod is fixedly connected to the connecting plate, and the movable rod is rotatably connected to a round rod.

[0010] Preferably, the top of the workbench is provided with a square groove, and a horizontal plate is fixedly connected to the opposite side of the square groove near the bottom inner wall.

[0011] Preferably, an electric telescopic rod is fixedly connected to the center of the horizontal plate, and a support plate is fixedly connected to one end of the electric telescopic rod.

[0012] Preferably, the clamping plate has multiple anti-slip grooves equidistantly spaced on one side.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. This utility model uses a controller to retract an electric telescopic rod, causing it to move a support plate downwards to a certain distance from the bottom of the metal box, preventing the metal box from colliding with the support plate during rotation. Then, based on the clamping plate holding the metal box, the controller starts a second motor at the corresponding position, causing its output shaft to drive a worm gear to rotate. With the meshing of the worm gear and worm wheel, the worm wheel rotates, synchronously driving the second movable rod and the clamping plate to rotate, flipping the metal box so that its bottom faces upwards. This facilitates the operation of a grinder by a robotic arm to grind the bottom of the metal box. This process is time-saving and labor-saving, thereby improving the efficiency of flexible grinding of the metal box.

[0015] 2. In this utility model, the controller starts the motor, causing its output shaft to drive the rotating shaft and disc to rotate. A force is applied to the movable bars via a pair of round rods, causing one of the adjacent movable bars to exert a pushing force on the connected movable rod 1 via a second round rod, causing the movable rod 1 to slide outwards. This simultaneously moves the connecting plate, the second movable rod, and the clamping plate outwards, moving the clamping plate away from two surfaces of the metal housing. Conversely, the other movable bar applies a pulling force to the connected movable rod 1 via a second round rod, causing the movable rod 1 to move inwards. This simultaneously moves the connecting plate, the second movable rod, and the clamping plate inwards, causing the clamping plate to press against the other two surfaces of the metal housing. The metal box is clamped and fixed in place. At this time, with the cooperation of the robotic arm and the grinder, the top, interior, and weld seams of two surfaces of the metal box can be ground. Then, the controller controls the motor to reverse, so that the clamping plate clamps and fixes two surfaces of the metal box, moving the clamping plate away from the other two surfaces of the metal box. In this way, the weld seams of the other two surfaces of the metal box can be ground. This clamping and fixing method can be used to fix the metal box. By changing the clamping surface of the clamping plate, it is convenient for the grinder to grind the weld seams of the top, interior, and surrounding surfaces of the metal box.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein, and therefore the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Examples, such as Figure 1-4 As shown, this utility model provides a flexible grinding device for weld seams of metal boxes, including: a workbench 1, a robotic arm 101 fixedly connected to one side of the workbench 1, a grinder 102 provided at one end of the robotic arm 101, and multiple fixed plates 304 fixedly connected to the top of the workbench 1. A movable rod 303 is movably connected to one side of the fixed plate 304 near the top, and a clamping plate 305 is fixedly connected to one end of the movable rod 303. Connecting plates 302 are provided around the workbench 1. The movable rod 303 is rotatably connected to the connecting plates 302. Two fixed blocks 4 are symmetrically fixedly connected to one side of each of the two connecting plates 302. A worm gear 401 is rotatably connected to the opposite side of each of the two fixed blocks 4. A motor 402 is fixedly connected to one side of each of the two fixed blocks 4. The output end of the motor 402 is fixedly connected to one end of the worm gear 401. A worm wheel 403 is fixedly connected to one end of each of the two movable rods 303, and the worm wheel 403 is threadedly connected to the worm gear 401.

[0025] Furthermore, such as Figure 1-4 As shown, a support frame 3 is fixedly connected to the bottom of the workbench 1. A rotating shaft 311 is rotatably connected to the center of the bottom of the support frame 3. A disc 306 is fixedly connected to one end of the rotating shaft 311. A motor 310 is fixedly connected to the bottom of the support frame 3. The output end of the motor 310 is fixedly connected to the other end of the rotating shaft 311. The motor 310 is started by the controller, so that its output shaft drives the rotating shaft 311 and the disc 306 to rotate.

[0026] Furthermore, such as Figure 1-4 As shown, multiple circular rods 307 are symmetrically and fixedly connected to each other on the top of the disk 306. A movable bar 308 is rotatably connected to the outer surface of the circular rod 307. A circular rod 309 is fixedly connected to the top of the movable bar 308 away from the circular rod 307. With the above arrangement, when the disk 306 rotates, a force can be applied to the movable bar 308 through the circular rod 307, so that the movable bar 308 rotates around the circular rod 307 at an appropriate angle.

[0027] Furthermore, such as Figure 1-4 As shown, the four arms of the support frame 3 are slidably connected with movable rod 301. Movable rod 301 is fixedly connected to the connecting plate 302. Movable rod 301 is rotatably connected to round rod 309. With the above arrangement, round rod 309 can rotate around movable rod 301 at an appropriate angle. When movable rod 301 is subjected to force, it will slide to one side, and simultaneously drive the connecting plate 302 to move.

[0028] Furthermore, such as Figure 1-4 As shown, a square groove 103 is provided on the top of the workbench 1. A horizontal plate 2 is fixedly connected to the opposite side of the square groove 103 near the bottom inner wall. The square groove 103 facilitates the installation of the horizontal plate 2.

[0029] Furthermore, such as Figure 1-4 As shown, an electric telescopic rod 202 is fixedly connected to the center of the horizontal plate 2. A support plate 201 is fixedly connected to one end of the electric telescopic rod 202. The electric telescopic rod 202 is started by the controller, so that it extends or retracts, driving the support plate 201 to move up or down an appropriate distance, thereby moving the metal box to the appropriate position.

[0030] Furthermore, such as Figure 1-4 As shown, multiple anti-slip grooves are equidistantly provided on one side of the clamping plate 305. The anti-slip grooves improve the stability of the clamping plate 305 in clamping the metal box.

[0031] Working principle: In use, the metal box is first placed on the support plate 201. Then, the controller starts the electric telescopic rod 202, causing it to extend or retract, moving the support plate 201 up or down an appropriate distance, thus moving the metal box to the desired position. Next, the controller starts the motor 310, causing its output shaft to drive the rotating shaft 311 and the disc 306 to rotate. The circular rod 307 applies a force to the movable bar 308, causing one of the adjacent movable bars 308 to exert a pushing force on the connected movable rod 301 through the circular rod 309, causing the movable rod 301 to slide outwards. The synchronous belt... The movable connecting plate 302, movable rod 2 303, and clamping plate 305 move outwards, moving the clamping plate 305 away from two surfaces of the metal box. Meanwhile, another movable bar 308 applies a pulling force to the connected movable rod 1 301 via the round rod 2 309, causing the movable rod 1 301 to move inwards. Simultaneously, this moves the connecting plate 302, movable rod 2 303, and clamping plate 305 inwards, clamping the clamping plate 305 to hold and fix the other two surfaces of the metal box. This clamps and fixes the metal box in place. At this time, with the cooperation of the robotic arm 101 and the grinder 102, the top, interior, and weld seams of two of the metal boxes can be ground. Then, by controlling the motor 310 to reverse, the clamping plate 305 can clamp and fix two surfaces of the metal box, moving the clamping plate 305 away from the other two surfaces of the metal box. This allows for continued grinding of the weld seams on the other two surfaces of the metal box. This clamping and fixing of the metal box, along with changing the clamping surface of the clamping plate 305, facilitates grinding of the weld seams on the top, interior, and surrounding surfaces of the metal box by the grinder 102. When grinding of the bottom of the metal box is required, the controller controls the electric telescopic rod 202 to retract, causing it to move the support plate 201 downwards. To prevent the metal box from rotating and colliding with the support plate 201, the metal box is positioned at a certain distance from the bottom of the metal box. Then, the clamping plate 305 holds the metal box, and the controller starts the motor 402 at the corresponding position, causing its output shaft to drive the worm gear 401 to rotate. With the meshing of the worm gear 401 and the worm wheel 403, the worm wheel 403 rotates, synchronously driving the movable rod 303 and the clamping plate 305 to rotate, thus flipping the metal box so that its bottom faces upward. This makes it easier for the robotic arm 101 to operate the grinder 102 to grind the bottom of the metal box. This process is more time-saving and labor-saving, thereby improving the efficiency of flexible grinding of the metal box.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
