The second L-shaped frame 231 rises and falls synchronously with the first L-shaped frame 223. The anti-falling block 237 can prevent the two second springs 236 from breaking and causing the entire second L-shaped frame 231 to fall downward. The sliding block 29 can also be installed through the second L-shaped frame 231, so that the second L-shaped frame 231 can be further moved up and down stably under the limit of the guide column 28 on the support block 27.

At this time, the rotating end of the tightening mechanism 2 will elastically rest on the workpiece clamped by the clamping mechanism 1, so the tightening mechanism 2 will not hard squeeze the workpiece clamped by the clamping mechanism 1, so at this time the tightening mechanism 2 can both tighten the workpiece and will not damage the workpiece, thereby ensuring the safety of the workpiece tightening and improving the tightening efficiency.

[0045] The first slide rail 13 in the clamping mechanism 1 can be installed in a specified position and provide a sliding track for the first slider 12 on the base 11. Since a loading rack 14 is provided in the middle position of the top surface of the base 11, and electric clamps 15 are provided on the top surface of the base 11 and on both sides of the loading rack 14, the loading rack 14 can facilitate the staff to accurately place the workpiece, and then the two electric clamps 15 are operated to clamp and position the placed workpiece, thereby ensuring the stability of the subsequent tightening of the workpiece. The first electric push rod 17 can be fixed on the fixing frame 3 through the mounting frame 18, and its telescopic end can be connected to the base 11 through the connecting frame 16. Therefore, through the extension and retraction of the first electric push rod 17, the base 11 can be driven to move along the first slide rail 13 through the first slider 12, thereby adjusting the position of the base 11, so that the staff can place the workpiece on the loading rack 14, and can also move the placed workpiece to the bottom of the tightening mechanism 2, or move the tightened workpiece out, so that the staff can take it out conveniently.

Since a guide assembly 23 is provided at the bottom of the movable end of the lifting assembly 22, and the two sides of the top surface of the guide assembly 23 respectively pass through the two sides of the movable end of the lifting assembly 22, and at the same time, the fastening rod 25 runs through one side of the guide component 23, so the fastening rod 25 can be movably plugged through the guide component 23, so that the fastening rod 25 can rotate smoothly, and the lifting component 22 and the guide component 23 can be limited and guided through the second slide rail 26, so that the two can move up and down smoothly. Since a support block 27 is provided on one side of the bottom of the outer wall of the vertical plate 21, and guide columns 28 are fixedly plugged on both sides of the top surface of the support block 27, and the sliding block 29 on one side of the guide component 23 is plugged and connected with the two guide columns 28, the sliding block 29 can be limited and guided through the guide columns 28 on the support block 27, thereby improving the stability of the upward and downward movement of the guide component 23, and the lifting component 22 and the guide component 23 can be shielded and protected through the protective cover 210, thereby improving the safety of the use of the two.

[0047] The second electric push rod 222 in the lifting assembly 22 can be fixed on the vertical plate 21 through the support frame 221, and can also be installed and fixed to the first L-shaped frame 223. Then, through the first L-shaped frame 223, it can not only slide smoothly on the second slide rail 26 through the second slider 228, but also provide opening space for the two second through holes 225, the third through hole 226 and the two fourth through holes 227.

Through the motor frame 2241, the motor 24 can be installed, and the two fixed tubes 2243 can be installed and fixed through the two first through holes 2242. Then, through the movable column 2244, it can be plugged into the inner cavity of the fixed tube 2243 and can be fixed to the bottom surface of the first L-shaped frame 223 through the first fixing screw 2246. At the same time, the first spring 2248 inserted on it can be limited by the second fixing screw 2247. Since the bottom end of the first spring 2248 is against the top of the fixing tube 2243, under the action of the first spring 2248, when the fastening rod 25 is against the workpiece, the pressing force will be transmitted to the motor 24, and then can be transmitted to the motor frame 2241. Then the motor frame 2241 will move downward, and the first spring 2248 will provide it with a downward elastic force. Therefore, the fastening rod 25 is elastically against the workpiece at this time, so it will not damage the workpiece, and at the same time it can ensure the stability of the fastening rod 25 fastening the workpiece. The motor 24 can be conveniently installed through the third through hole 226, and the guide assembly 23 can be installed through the two fourth through holes 227, so that the guide assembly 23 can move downward synchronously with the guide assembly 23.

The limiting frame 233 can be used to penetrate and insert the fastening rod 25, and the rotating fastening rod 25 can be limited, thereby ensuring the stability of its rotation. Then, the two clamping frames 235 can be respectively fixed to the inner cavities of the two fourth through holes 227, and the two columns 234 can be movably inserted, and at the same time, the top of the second spring 236 sleeved on the column 234 can be fixedly connected. Since the bottom end of the second spring 236 is fixed on the upper surface of the second L-shaped frame 231, the pulling of the second spring 236 can make the second L-shaped frame 231 move upward and downward, thereby ensuring the stability of the second L-shaped frame 231. The second L-shaped frame 231 rises and falls synchronously with the first L-shaped frame 223. The anti-falling block 237 can prevent the two second springs 236 from breaking and causing the entire second L-shaped frame 231 to fall downward. The sliding block 29 can also be installed through the second L-shaped frame 231, so that the second L-shaped frame 231 can be further moved up and down stably under the limit of the guide column 28 on the support block 27. Since an internal threaded hole 239 is provided on the upper surface of the second L-shaped frame 231 and located between the two columns 234, and a stop column 2310 is rotatably connected to the inner cavity of the internal threaded hole 239, a certain distance can be maintained between the second L-shaped frame 231 and the second L-shaped frame 231, so that the two can be squeezed. At the same time, by rotating the stop column 2310, its position height in the internal threaded hole 239 can be adjusted, thereby improving its flexibility in use.

[0049] In summary, the device can perform fastening processing on the workpiece without damaging the workpiece, thereby ensuring the safety of the workpiece fastening and improving the fastening efficiency.
