Description

Technical Field

[0001] This utility model relates to the field of metal casing processing technology, and in particular to a grinding equipment for metal casing processing. Background Technology

[0002] In the manufacturing process of metal enclosures (such as chassis, electrical cabinets, control boxes, protective shells, etc.), welding and cutting (laser, plasma, shearing, etc.) are common processing steps. These steps inevitably produce processing residues at the edges and corners of the workpiece, such as weld reinforcement and weld scars, raised weld beads and irregular slag residues formed after welding, sharp edges and burrs.

[0003] For the grinding of edges and corners of metal casings, existing technologies mostly rely on manual hand-held grinding equipment. However, this manual grinding operation requires the operator to perform frequent physical movements, such as moving the grinding equipment up and down and left and right. After working for a long time, the grip of the grinding equipment can become unstable. Moreover, this grinding method cannot process an edge or corner simultaneously, which affects work efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a grinding device for processing metal casings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A grinding device for processing metal casings includes a worktable. A pair of support frames are rotatably mounted on one side of the worktable via a support shaft. A grinding roller is mounted in the middle of each support frame. The grinding roller is driven to rotate by a motor. In its natural state, there is a certain gap between each adjacent grinding roller. A pair of corner limiting blocks are symmetrically installed on the side away from the grinding roller. The corner limiting blocks are used to fit the side wall of the workpiece shell. Adjacent corner limiting blocks are connected as a whole by a U-shaped plate. The U-shaped plate achieves single linear movement through the sliding groove opened on the worktable. Multiple limiting rods are inserted through the middle of the U-shaped plate. The two ends of the limiting rods are supported and fixed by support blocks. The support blocks are connected to the U-shaped plate by springs.

[0006] In addition, a preferred structure is that a notch is provided on one side of the workbench, and support shafts are rotatably installed on both sides of the notch, with a support frame fixedly connected to the middle of each support shaft.

[0007] In addition, a preferred structure is that a motor is installed at the bottom of the support frame, the output end of the motor is connected to a grinding roller, and the other end of the grinding roller is rotatably installed in the middle of the support frame.

[0008] In addition, a preferred structure is that a pair of tension springs are installed at the bottom of the worktable, and the other end of the tension springs is connected to the bottom side of the support frame. When the support frame rotates around the support roller, the tension springs deform.

[0009] In addition, a preferred structure is that a pair of sliding grooves are provided in the middle of the workbench surface, and the two vertical sections of the U-shaped plate are slidably installed in the sliding grooves, and the two ends of the U-shaped plate are inclinedly provided with corner limiting blocks.

[0010] In addition, a preferred structure is that a pair of support blocks are installed on the bottom side of the workbench surface, the support blocks are connected by a pair of limiting rods, and a U-shaped plate is installed on the upper limit of the limiting rods.

[0011] The beneficial effects of this utility model are as follows: In this invention, a pair of corner limiting blocks are provided on the worktable to limit the two sides of the metal cover, ensuring that its corners are aligned with the grinding roller assembly during processing. The grinding roller assembly consists of a rotatable support frame, grinding rollers, and tension springs. The two grinding rollers simultaneously grind the entire surface of the workpiece corners, and the support frame adaptively rotates to match the corners. After grinding, the spring drives the corner limiting blocks to assist the workpiece in resetting and retracting. Compared with traditional manual operation, this invention avoids operational inconvenience, reduces workload, and ensures grinding efficiency. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-5 A grinding device for processing metal casings includes a worktable 1. A pair of support frames 4 are rotatably mounted on one side of the worktable 1 via a support shaft 43. A grinding roller 41 is assembled in the middle of each support frame 4. The grinding roller 41 is driven to rotate by a motor component 42. A certain gap is left between each adjacent grinding roller 41. A pair of corner limiting blocks 3 are symmetrically installed on the side away from the grinding roller 41. The corner limiting blocks 3 are used to fit the side wall of the workpiece shell. Adjacent corner limiting blocks 3 are connected into a whole by a U-shaped plate 31. The U-shaped plate 31 achieves single linear movement through the sliding groove 2 opened on the worktable 1. Multiple limiting rods 34 are passed through the middle of the U-shaped plate 31. The two ends of the limiting rods 34 are supported and fixed by the support blocks 32. The support blocks 32 and the U-shaped plate 31 are connected by springs 33. When the U-shaped plate 31 moves, the springs 33 deform.

[0016] A notch is provided on one side of the workbench 1, and a support shaft 43 is rotatably installed on both sides of the notch. A support frame 4 is fixedly connected to the middle of each support shaft 43, and the support frame 4 can rotate through the support shaft 43.

[0017] A motor component 42 is installed at the bottom of the support frame 4. The output end of the motor component 42 drives the grinding roller 41. The other end of the grinding roller 41 is rotatably installed in the middle of the support frame 4.

[0018] A protective cover 44 is provided on the upper part of the motor component 42 to block the processing debris falling from above.

[0019] A pair of tension springs 5 ​​are installed at the bottom of the workbench 1. The other end of the tension springs 5 ​​is connected to the bottom side of the support frame 4. When the support frame 4 rotates around the support roller 43, the tension springs 5 ​​deform.

[0020] A pair of sliding grooves 2 are provided in the middle of the workbench 1. The vertical sections of the two sides of the U-shaped plate 31 are slidably installed in the sliding grooves 2, and the two ends of the U-shaped plate 31 are inclinedly provided with corner limiting blocks 3.

[0021] A pair of support blocks 32 are installed on the bottom side of the workbench 1. The support blocks 32 are connected by a pair of limit rods 34. A U-shaped plate 31 is installed on the upper limit of the limit rods 34.

[0022] In this embodiment, the operator places the metal shell to be processed on the worktable with its corners facing the worktable 1, and pushes the workpiece until it is released from the corner limiting block 3 on the worktable. The corner limiting block 3 is set at an angle to limit the outer wall of the shell. At this time, the shell will move together with the corner limiting block 3, and the corner of the shell will gradually approach the grinding roller 41 until it is released. The two sides of the corner of the shell will contact the two grinding rollers 41 to achieve grinding.

[0023] Intuitively, continuing to push the housing allows the edges and corners of the housing to penetrate deeper between the two grinding rollers 41 for grinding to meet different grinding needs. When the two grinding rollers 41 are squeezed by the edges and corners, they will be passively rotated through the support shaft 43, forming an "outward unfolding" posture, thereby adaptively fitting the edges and corners of the housing.

[0024] The rotated support frame 4 will cause the tension spring 5 to undergo tensile deformation, and the reset operation of the support frame 4 is achieved through the deformation of the tension spring 5.

[0025] After the grinding is completed, as the operator retracts the housing, the corner limiting block 3, which is pushed, retracts under the deformation of the spring 33.

[0026] Furthermore, it can be intuitively understood that the grinding roller 41 will generate processing debris during processing. Some of the debris may fall into the slide groove 2. Since the sliding of the U-shaped plate 31 is mainly achieved by the limiting rod 34, and the slide groove 2 has a through structure that ensures that most of the debris falls off, the small amount of debris has minimal impact on the normal operation of the U-shaped plate 31. The existing loss is within the normal and reasonable range, which is easy to understand intuitively and will not be explained further.

[0027] Compared to traditional operation methods, this device avoids the need for operators to actively and repeatedly move the grinding equipment. Grinding can be performed simply by operating the workpiece, effectively reducing the workload. The integrated grinding roller 41 can effectively grind the edges and corners simultaneously and the entire surface, which significantly improves the grinding quality compared to manual operation.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
