[0019] See also Figures 1 to 3A clamping tool for processing hexagonal bolts includes a base 1 and a vertical plate 3. A motor 4 is installed at the left end of the vertical plate 3. The output end of the motor 4 passes through the vertical plate 3 and is fixedly connected to a support plate 5. The left end of the support plate 5 is fixedly connected to a mounting plate 6. The front end of the mounting plate 6 is movably connected to two upper and lower distributed screw rods 7. The outer walls of the two screw rods 7 are threadedly connected to two symmetrically distributed sliders 8. The outer walls of the two sliders 8 are fixedly connected to a clamping plate 10 through a connecting rod 9.

[0020] The front ends of the two screw rods 7 are fixedly connected to the gears 11, the front end of the support plate 5 is movably connected to the drive plate 14, the upper and lower ends of the drive plate 14 are fixedly connected to the racks 12, and the two racks 12 are respectively engaged with the two gears 11;

[0021] A conveyor 17 is provided at the right end of the support plate 5 .

[0022] In this embodiment: when in use, the hexagonal bolts to be processed are transported by the conveyor 17, and when one of the hexagonal bolts moves between the two clamping plates 10 at the upper end, the electric push rod 16 is started to drive the cross plate 13 to move. When the cross plate 13 moves, the driving plate 14 and the two racks 12 are pulled to move. When the rack 12 moves, the two gears 11 meshed with it are driven to rotate, which will then drive the two screw rods 7 connected thereto to rotate in the opposite direction, so that the two sliders 8 at the upper end and the clamping plate 10 move relative to each other to clamp the hexagonal bolt, and the support plate 5 is driven to rotate by starting the motor 4. The rotation of the support plate 5 can drive the clamping plate 10 and the clamped hexagonal bolt to rotate 90 degrees, so that the hexagonal bolt is placed horizontally, and the hexagonal bolt is processed by the wire extruder. After the processing is completed, the motor 4 continues to drive the support plate 5 to rotate 90 degrees;

[0023] The electric push rod 16 is started to move the two sliders 8 and the clamping plate 10 at the lower end in opposite directions, so that the processed hexagonal bolts fall off.

[0024] As a technical optimization solution of the present invention, the front end of the driving plate 14 is fixedly connected to the horizontal plate 13, the left end of the support plate 5 is fixedly connected to the fixed plate 15, and the lower end of the fixed plate 15 is installed with an electric push rod 16. The output end of the electric push rod 16 passes through the fixed plate 15 and is fixedly connected to the horizontal plate 13.

[0025] In this embodiment, the horizontal plate 13 can be driven to move by the electric push rod 16 .

[0026] As a technical optimization solution of the present invention, a second electric push rod 2 is installed at the left end of the base 1 , and the output end of the second electric push rod 2 passes through the base 1 and is fixedly connected to the vertical plate 3 .

[0027] In this embodiment, the vertical plate 3 can be driven to move by the second electric push rod 2 .

[0028] As a technical optimization solution of the present invention, the right end of the slider 8 abuts against the support plate 5 .

[0029] In this embodiment, the right end of the slider 8 abuts against the support plate 5 to prevent the slider 8 from axially rotating.

[0030] As a technical optimization solution of the present invention, the upper end of the conveyor 17 is fixedly connected to two limit plates 18 located above the conveyor belt.

[0031] In this embodiment, the hexagonal bolt can be limited by the limiting plate 18 so that the plane of the hexagonal bolt is parallel to the clamping plate 10, which facilitates the auxiliary clamping operation of the clamping plate 10.

[0032] As a technical optimization solution of the present invention, both screw rods 7 are reverse double-threaded screw rods.

[0033] In this embodiment, the two sliders 8 connected to the screw rod 7 can be conveniently driven to move in opposite directions by the reverse double-thread screw rod.

[0034] Working principle: When in use, the hexagonal bolts to be processed are conveyed through the conveyor 17. When one of the hexagonal bolts moves between the two clamping plates 10 at the upper end, the electric push rod 16 is started to drive the cross plate 13 to move. When the cross plate 13 moves, it pulls the driving plate 14 and the two racks 12 to move. When the racks 12 move, they drive the two gears 11 meshing with them to rotate, which in turn drives the two screw rods 7 connected to them to rotate in the opposite direction, so that the two sliders 8 at the upper end and the clamping plate 10 move relative to each other, thereby clamping the hexagonal bolt.

[0035] After clamping, the second electric push rod 2 drives the vertical plate 3 to move to the left, so that the clamping plate 10 is away from the conveyor 17, and then the motor 4 is started to drive the support plate 5 to rotate. The rotation of the support plate 5 can drive the clamping plate 10 and the clamped hexagonal bolt to rotate 90 degrees, so that the hexagonal bolt is placed horizontally, and the hexagonal bolt is processed by the wire extruder. After the processing is completed, the motor 4 continues to drive the support plate 5 to rotate 90 degrees.

[0036] At the same time, the second electric push rod 2 drives the vertical plate 3 to move to the right, so that the other pair of clamping plates 10 is located at the upper end of the conveyor 17;

[0037] Then start the electric push rod 16 to drive the cross plate 13 to move. When the cross plate 13 moves, it pulls the driving plate 14 and the two racks 12 to move. When the rack 12 moves, the driving gear 11 and the screw rod 7 rotate. The two clamping plates 10 at the upper end move relative to each other to clamp the hexagonal bolts. At the same time, the two clamping plates 10 at the lower end move in the opposite direction to make the processed hexagonal bolts fall off.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
