[0001] This utility model relates to the field of shielding cover processing technology, and more specifically, it relates to a tooling for shielding cover processing. Background Technology
[0002] A shield is a protective structure used to isolate electromagnetic interference (EMI), radio frequency interference (RFI), physical contact, or environmental influences. It is widely used in electronics, electrical engineering, communications, medical, industrial equipment, and aerospace industries.
[0003] Tooling for shielding cover processing refers to specialized process equipment used for positioning, clamping, supporting, guiding, or inspecting during the manufacturing and processing of shielding covers (such as metal electromagnetic shielding covers, chassis, and shells). Its design directly affects the processing accuracy, consistency, efficiency, and yield of the shielding cover.
[0004] Existing tooling is not suitable for fitting shielding covers of different sizes, and the existing tooling mechanism lacks positioning, resulting in inconsistent processing positions when processing shielding covers of the same size, which affects the processing effect. Utility Model Content
[0005] (a) Technical problems to be solved To address the problems existing in the prior art, this utility model provides a tooling for processing shielding covers, thereby solving the technical problem mentioned in the background art that existing tooling is inconvenient to adapt and place well when facing shielding covers of different sizes.
[0006] Technical solution To achieve the above objectives, this utility model provides the following technical solution: A tooling for processing a shielding cover includes a workbench with four sets of support legs at the bottom. The top of the workbench has upright plates on the left and right sides. Each of the two sets of upright plates has a cylinder at its outer end. The output ends of the two sets of cylinders pass through the two sets of upright plates and are fitted with two sets of clamping plates. A positioning plate is provided on the rear side of the top of the workbench, and a drop outlet is provided in the middle of the workbench.
[0007] This utility model is further configured such that a sliding groove is provided on the rear side of the top of the workbench, a screw is rotatably disposed in the sliding groove, an adjusting block is threaded on the screw, the adjusting block is slidably connected to the sliding groove, the adjusting block is installed at the bottom of the positioning plate, a handle is provided at the rear end of the screw extending to the rear side of the workbench, a lever is rotatably disposed on the lower side of the rear end of the handle, and a lever is provided at the rear side of the top of the workbench, the lever corresponding to the position of the sliding groove. The position of the positioning plate is adjusted according to the size of the shielding cover. The lever drives the handle to rotate, the handle drives the screw to be threadedly connected to the adjusting block, and the adjusting block slides in the sliding groove of the workbench, thereby adjusting the position of the positioning plate. After the position of the positioning plate is adjusted, the shielding cover is placed on the top of the workbench, so that the shielding cover contacts and is positioned with the positioning plate, which facilitates the positioning of shielding covers of different sizes and ensures the processing consistency of shielding covers of uniform size.
[0008] The present invention is further configured such that a guide hopper is provided at the bottom end of the drop port of the workbench, and a collection box is provided at the output end of the guide hopper. When the shield is drilled, the debris after drilling is guided into the collection box through the drop port of the workbench and the guide hopper for collection, which facilitates the collection of debris generated during the processing of the shield.
[0009] The present invention is further configured such that two sets of support plates are provided inside the drop opening of the workbench, and the shielding cover can be supported by the two sets of support plates.
[0010] This utility model is further configured such that T-shaped blocks are provided at the front and rear ends of both sets of support plates, and T-shaped grooves are provided on the left and right sides of the front and rear ends of the drop outlet. The four sets of T-shaped blocks are slidably connected to the four sets of T-shaped grooves respectively. The outer ends of the four sets of T-shaped grooves are all connected to long grooves, and the outer ends of the four sets of T-shaped blocks are threaded with bolts. The four sets of bolts slide within the four sets of long grooves. When it is necessary to adjust the position of the two sets of support plates according to the size of the shielding cover, the four sets of bolts are loosened, and then the two sets of support plates drive the four sets of T-shaped blocks to slide within the four sets of T-shaped grooves on the worktable. When the two sets of support plates slide to the designated position, the four sets of bolts are rotated, and the four sets of bolts are threadedly connected to the four sets of T-shaped blocks, thereby fixing the two sets of support plates and facilitating the adjustment of the position of the two sets of support plates according to the size of the shielding cover.
[0011] The present invention is further configured such that vacuum pumps are provided on the left and right rear sides of the top of the workbench, and air guide pipes are provided at the input ends of the two sets of vacuum pumps. A chamber is provided inside the two sets of clamping plates, and the input ends of the two sets of air guide pipes are connected to the two sets of clamping plates. Multiple sets of suction cups are connected to the inner ends of the two sets of clamping plates. When the two sets of clamping plates move inward to clamp the shielding cover, the multiple sets of suction cups come into contact with the shielding cover. Then, the two sets of vacuum pumps are turned on, and the multiple sets of suction cups are evacuated, thereby clamping and fixing the shielding cover with the multiple sets of suction cups. This can improve the fixing effect of the shielding cover and avoid wear caused by direct contact between the clamping plates and the shielding cover.
[0012] The present invention is further configured such that the front end and the rear end of the adjusting block are provided with folding covers, and the two sets of folding covers are respectively connected to the front end and the rear end of the sliding groove of the worktable. By providing folding covers, the screw can be protected, and debris can be prevented from being introduced into the sliding groove of the worktable, causing the screw and the adjusting block to jam.

Includes a workbench with four sets of support legs at the bottom. Vertical plates are installed on the left and right sides of the top of the workbench. Cylinders are installed at the outer ends of both sets of vertical plates. The output ends of the two sets of cylinders pass through the two sets of vertical plates and are fitted with two sets of clamping plates. A positioning plate is installed on the rear side of the top of the workbench. A drop outlet is connected to the middle of the workbench. When a shielding cover is placed on the top of the workbench, the two sets of cylinders are opened, causing the two sets of clamping plates to move inwards to clamp and fix the shielding cover. This facilitates the clamping and fixing of shielding covers of different sizes.
[0014] 2. A screw is rotatably mounted in the sliding groove of the worktable. An adjusting block is threaded onto the screw. The adjusting block is installed at the bottom of the positioning plate. A handle is provided at the rear end of the screw extending to the rear side of the worktable. A lever is rotatably mounted on the lower rear end of the handle.

[0020] Please see Figure 1-5A tooling for processing a shielding cover includes a workbench 1, four sets of support legs 2 at the bottom of the workbench 1, upright plates 3 on the left and right sides of the top of the workbench 1, cylinders 4 at the outer ends of the two sets of upright plates 3, and two sets of clamping plates 5 passing through the two sets of upright plates 3 respectively. A positioning plate 6 is provided on the rear side of the top of the workbench 1, and a drop hole is provided in the middle of the workbench 1. In this embodiment, the shielding cover is placed on the top of the workbench 1, and then the two sets of cylinders 4 are opened. The two sets of cylinders 4 drive the two sets of clamping plates 5 to move inward to clamp and fix the shielding cover, which is convenient for clamping and fixing shielding covers of different sizes.
[0021] Please see Figures 1-3 As one embodiment of the positioning plate 6, the workbench 1 in this utility model is provided with a sliding groove at the rear of its top end. A screw 7 is rotatably provided in the sliding groove. An adjusting block 8 is threaded on the screw 7. The adjusting block 8 is slidably connected to the sliding groove. The adjusting block 8 is installed at the bottom end of the positioning plate 6. A handle 9 is provided at the rear end of the screw 7 extending to the rear side of the workbench 1. A handle 10 is rotatably provided at the lower rear end of the handle 9. A handle 11 is provided at the rear of the top end of the workbench 1. The handle 11 corresponds to the position of the sliding groove. Folding covers 20 are provided at both the front and rear ends of the adjusting block 8. The two sets of folding covers 20 are respectively connected to the front and rear ends of the sliding groove of the workbench 1. Specifically, the position of the positioning plate 6 is adjusted according to the size of the shielding cover. The handle 9 is rotated by the lever 10, and the handle 9 drives the screw 7 to be threadedly connected to the adjusting block 8. The adjusting block 8 slides in the sliding groove of the worktable 1, thereby adjusting the position of the positioning plate 6. After the position of the positioning plate 6 is adjusted, the shielding cover is placed on the top of the worktable 1 so that the shielding cover is in contact with the positioning plate 6 for positioning. This facilitates the positioning of shielding covers of different sizes and ensures the processing consistency of shielding covers of the same size. By setting the folding cover 20, the screw 7 can be protected to prevent debris from being introduced into the sliding groove in the worktable 1 and causing the screw 7 and the adjusting block 8 to jam.
[0022] Please see Figure 1 , Figure 2 and Figure 5 As one embodiment of the workbench 1, the bottom end of the drop port of the workbench 1 in this utility model is provided with a guide hopper 12, the output end of the guide hopper 12 is provided with a collection box 13, and two sets of support plates 14 are provided inside the drop port of the workbench 1. Specifically, when the shield is drilled, the debris after drilling is guided into the collection box 13 through the drop port of the workbench 1 and the guide hopper 12 for collection, which facilitates the collection of debris generated during the processing of the shield. The shield can be supported by two sets of support plates 14.
[0023] Please refer to Figures 1-4 As a further embodiment of the support plate 14: T-shaped blocks 15 are provided at the front and rear ends of both sets of support plates 14, and T-shaped grooves are provided on the left and right sides of the front and rear ends of the drop outlet. The four sets of T-shaped blocks 15 are slidably connected to the four sets of T-shaped grooves respectively. The outer ends of the four sets of T-shaped grooves are all connected to long grooves. The outer ends of the four sets of T-shaped blocks 15 are all threaded with bolts 16, and the four sets of bolts 16 slide in the four sets of long grooves. Specifically, when it is necessary to adjust the position of the two sets of support plates 14 according to the size of the shielding cover, the four sets of bolts 16 are loosened, and then the two sets of support plates 14 drive the four sets of T-blocks 15 to slide in the four sets of T-slots of the workbench 1. After the two sets of support plates 14 slide to the designated position, the four sets of bolts 16 are rotated, and the four sets of bolts 16 are threadedly connected to the four sets of T-blocks 15, thereby fixing the two sets of support plates 14, which makes it easy to adjust the position of the two sets of support plates 14 according to the size of the shielding cover.
[0024] This invention provides vacuum pumps 17 on the left and right rear sides of the top of the workbench 1. Each set of vacuum pumps 17 has an air guide pipe 18 at its input end. Each set of clamping plates 5 contains a chamber. The input ends of the air guide pipes 18 are connected to the clamping plates 5. Multiple suction cups 19 are connected to the inner ends of each set of clamping plates 5. When the clamping plates 5 move inward to clamp the shielding cover, the suction cups 19 contact the shielding cover. Then, the vacuum pumps 17 are turned on, and the suction cups 19 draw a vacuum, thereby clamping and fixing the shielding cover. This improves the fixing effect of the shielding cover and avoids wear caused by direct contact between the clamping plates 5 and the shielding cover.
[0025] In summary, when using the overall equipment: Place the shielding cover on the two sets of support plates 14 at the top of the workbench 1, so that the shielding cover contacts and is positioned with the positioning plate 6. Then open the two sets of cylinders 4, which drive the two sets of clamping plates 5 to move inward, and the multiple sets of suction cups 19 contact the shielding cover. Then open the two sets of vacuum pumps 17, and the multiple sets of suction cups 19 draw a vacuum, so that the multiple sets of suction cups 19 clamp and fix the shielding cover.
[0026] When the position of the positioning plate 6 needs to be adjusted according to the size of the shielding cover, the handle 9 is rotated by the lever 10. The handle 9 then drives the screw 7 to be threadedly connected to the adjusting block 8. The adjusting block 8 then slides in the sliding groove of the worktable 1, thereby adjusting the position of the positioning plate 6.
[0027] When the shield is drilled, the debris after drilling is guided into the collection box 13 through the drop outlet of the workbench 1 and the guide hopper 12.
[0028] When it is necessary to adjust the position of the two sets of support plates 14 according to the size of the shielding cover, loosen the four sets of bolts 16, and then let the two sets of support plates 14 drive the four sets of T-shaped blocks 15 to slide in the four sets of T-shaped grooves of the workbench 1. After the two sets of support plates 14 slide to the designated position, rotate the four sets of bolts 16, and the four sets of bolts 16 will be threadedly connected to the four sets of T-shaped blocks 15, thereby fixing the two sets of support plates 14.
