[0002] High-strength bolts are a special type of bolts. Their characteristics make them an ideal choice in scenarios that require strength and durability. Simply put, high-strength bolts are bolts with extremely high tensile strength. They are specially processed and manufactured to withstand extremely high tension and shear forces without breaking. High-strength bolts require thread cutting on the outer wall during processing. A forming tool or a thread combing tool can be used to clamp and fix the bolt first, and then the clamping device can be rotated to make the outer wall of the bolt contact with the forming tool or thread combing tool to form threads. The following problems exist in the existing technology:

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] When it is necessary to clamp the cut high-strength bolt, the bolt is clamped into a clamping box 242 at the top of the front side of the turntable 23, and then the drive motor 22 is started to drive the entire turntable 23 to rotate clockwise, so that the clamping box 242 that clamps the bolt moves to the right, and the next clamping box 242 moves to the top of the front side of the turntable 23, and then the clamping operation is repeated until the first clamping box 242 that clamps the bolt moves to the bottom of the front side of the turntable 23 for cutting. After the thread of the bolt fixed in the bottom clamping box 242 is processed and falls off, the bolt in the next clamping box 242 can be moved to the bottom for thread cutting by rotating the turntable 23, and so on.

[0023] like Figure 3 As shown, a hanging plate 2421 is fixedly installed on one side of the inner wall of the clamping box 242 near the center of the turntable 23, and a limiting groove 2422 is provided on the front side of the hanging plate 2421. An electric telescopic rod 2423 is fixedly installed on one side of the inner wall of the clamping box 242 away from the center of the turntable 23. The electric telescopic rod 2423 is connected to an external power supply by a wire for power supply, and an arc-shaped clamping plate 2424 is fixedly installed on the top of the telescopic output end of the electric telescopic rod 2423. The arc-shaped clamping plate 2424 is positioned at the bottom of the clamping box 242. Below the limiting groove 2422, a fixing plate 2425 is provided on one side of the inner wall of the clamping box 242 near the center of the turntable 23, and the fixing plate 2425 is located at the rear side of the hanging plate 2421. A rotating motor 2426 is fixedly installed on the right side of the fixing plate 2425, and a flip plate 2427 is fixedly installed on the output shaft of the rotating motor 2426. A rubber block 2428 is fixedly installed on the front side of the flip plate 2427, and the rubber block 2428 is located at the rear side of the hanging plate 2421.

[0024] When installing the bolt, first push it into the limiting groove 2422 on the front side of the hanging plate 2421 in the inner cavity of the clamping box 242, then start the electric telescopic rod 2423 to move the arc clamping plate 2424 toward the limiting groove 2422 and clamp the bolt. After the bolt is processed, start the electric telescopic rod 2423 to lower and retract it, and at the same time start the rotating motor 2426 to drive the flip plate 2427 to flip forward quickly, and use the rubber block 2428 to knock the back side of the hanging plate 2421, so that the bolt falls forward into the collecting mechanism 4.

[0025] like Figure 4 , Figure 5As shown, the cutting mechanism 3 includes an L-shaped vertical plate 31, a hydraulic telescopic rod 32 is fixedly installed on the top of the L-shaped vertical plate 31, a thread comb 33 is fixedly installed on the output end of the hydraulic telescopic rod 32, and the left end of the thread comb 33 is located at the front side of the clamping box 242, and the collecting mechanism 4 includes a drop box 41, and the drop box 41 is located below the clamping box 242, and the inner wall of the drop box 41 is fixedly installed with an inclined screen 411 inclined forward, and a discharge hole 413 is opened at the lower front side of the drop box 41, and the discharge hole 413 is located at the front side of the inclined screen 411, and a bolt collection box 42 is fixedly installed on the front side of the drop box 41, and the bolt collection box 42 is located below the discharge hole 413, and a drawing hole is opened through the lower left side of the drop box 41, and a debris collection drawing box 412 is slidably arranged in the drawing hole;

[0026] By starting the hydraulic telescopic rod 32 on the top of the L-shaped vertical plate 31, the thread combing cutter 33 is driven to approach the bolt, and the rotating motor 241 is started at the same time to drive the overall clamping box 242 to rotate, so that the thread combing cutter 33 performs thread cutting when it contacts the rotating bolt. When the thread cutting of the high-strength bolt is completed and falls forward into the drop box 41, the aperture of the inclined screen 411 is not enough to drop the bolt, so the bolt will fall into the bolt collection box 42 along the inclined inclined screen 411 through the discharge hole 413, and the debris can fall into the debris collection pull-out box 412 through the inclined screen 411 for collection, and the debris collection pull-out box 412 can be pulled out for cleaning.

[0027] The working principle of the clamping device for high-strength bolt thread processing is described in detail below.

[0028] like Figure 1-5As shown, when it is necessary to clamp the cut high-strength bolt, the bolt is clamped into a clamping box 242 at the top of the front side of the turntable 23 and pressed into the limit groove 2422. Then, the electric telescopic rod 2423 is started to make the arc clamping plate 2424 move toward the limit groove 2422 and clamp the bolt. Then, the driving motor 22 is started to drive the entire turntable 23 to rotate clockwise, so that the clamping box 242 clamping the bolt moves to the right, and the next clamping box 242 moves to the top of the front side of the turntable 23. Then, the operation is repeated for clamping until the clamping box 242 that clamps the first bolt moves to the bottom of the front side of the turntable 23. Then, the hydraulic telescopic rod 32 on the top of the L-shaped vertical plate 31 is started to drive the thread combing cutter 33 to approach the bolt, and at the same time, the rotating motor 241 is started to drive the entire clamping box 242 to rotate, so that the thread combing cutter 33 contacts the rotating The thread cutting process is carried out when the bolt is rotated. After the bolt is processed, the electric telescopic rod 2423 is started to be lowered and retracted, and the rotating motor 2426 is started at the same time to drive the flip plate 2427 to flip forward quickly, and the rubber block 2428 is used to knock the back side of the hanging plate 2421, so that the bolt falls forward into the drop box 41. The aperture of the inclined screen 411 is not enough to drop the bolt, so the bolt will fall into the bolt collection box 42 through the discharge hole 413 along the inclined inclined screen 411, and the debris can fall into the debris collection pull-out box 412 through the inclined screen 411 for collection. When cleaning, just pull out the debris collection pull-out box 412, and after the thread processing of the bolt fixed in the bottom clamping box 242 is completed and falls, the bolt in the next clamping box 242 can be moved to the bottom for thread cutting by rotating the turntable 23, and so on.

[0029] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
