[0018] As Figures 1 to 3 shown, a screw end cover processing device includes a fixing bracket 1 with a U-shaped structure. A positioning component is detachably installed inside the fixing bracket 1. The positioning component includes a fixed seat 2. A storage groove is formed in the top surface of the fixed seat 2. A pressing plate 3 is arranged inside the storage groove. Two fixing grooves are symmetrically formed in the upper part inside the fixing bracket 1. Slide rails 8 are installed inside the fixing grooves. Fixed columns 9 slidably connected to the slide rails 8 are symmetrically fixed to both sides of the fixed seat 2. The fixed columns 9 are of I-shaped structure. A positioning block 10 is fixedly connected to the middle of the rear end of the fixed seat 2. Two mounting holes are formed in the positioning block 10. A slot adapted to the positioning block 10 is formed in the fixing bracket 1. And a jack corresponding to the position of the mounting hole is formed in the top surface of the fixing bracket 1. The jack penetrates through the slot, and a U-shaped positioning rod 11 is inserted into the jack. Support plates 12 for supporting and limiting the fixed seat 2 are fixedly connected to both sides inside the fixing bracket 1 below the fixing grooves.

[0019] Slide the fixing column 9 along the slide rail 8 into the interior of the fixing frame 1, so that the positioning block 10 is inserted into the slot, and the center lines of the mounting holes on the positioning block 10 and the jacks coincide. At this time, a positioning rod 11 can be inserted into the jack, and the connection and fixation of the fixed seat 2 and the fixing frame 1 can be realized. Both the fixing column 9 and the support plate 12 can play a role in supporting the fixed seat 2.

[0020] As Figure 3 and Figure 4 shown, a through groove is formed in the middle of the pressing plate 3, and a positioning cylinder 4 is fixedly connected to the outside of the through groove at the top. Limiting holes are provided in both the positioning cylinder 4 and the pressing plate 3. Ear plates 5 are fixedly connected to the corners on the front and rear sides of the pressing plate 3, and a threaded rod 6 passing through the ear plates 5 is fixedly connected to the top surface of the fixed seat 2. A nut 7 is installed on the threaded rod 6.

[0021] A rectangular groove communicating with the storage groove is formed in the bottom surface of the fixed seat 2. The length and width of the pressing plate 3 are the same as the length and width of the storage groove, and through holes corresponding to the positions of the limiting holes on the pressing plate 3 are formed in the fixed seat 2.

[0022] Place the screw rod end cover in the storage groove with the connecting part facing upward, cover the pressing plate 3. At this time, the positioning cylinder 4 is sleeved on the outside of the connecting part, and then the nut 7 is installed and tightened on the threaded rod 6 to realize the installation and fixation of the screw rod end cover; then the fixed seat 2 can be installed on the fixing frame 1.

[0023] In specific use, place the screw rod end cover in the storage groove and install the pressing plate 3. Slide the fixing column 9 along the slide rail 8 into the interior of the fixing frame 1 and fix it with the positioning rod 11. At this time, drilling operations can be performed on the connecting part and the installation part of the screw rod end cover through the limiting holes provided in the positioning cylinder 4 and the pressing plate 3. There is no need for manual marking of the drilling positions, and the phenomenon of the drill bit slipping on the surface of the screw rod end cover can be effectively reduced through the setting of the limiting holes, making the drilling safer and more stable.
