[0002] Bolts are widely used as fasteners in the industrial field. For example, wind turbines require a large number of high-strength hexagonal bolts. Hexagonal bolts refer to fasteners composed of a head and a screw. Bolts are divided into iron bolts and stainless steel bolts according to their materials. When the hexagonal bolts are threaded, they are clamped and fixed using a hexagonal bolt processing clamping tool, and then clamped.

After processing one hexagonal bolt, the processed hexagonal bolt must be removed, and the next hexagonal bolt to be processed must be fixed before processing can continue, which wastes time in replacing the hexagonal bolts, thereby reducing the work efficiency of hexagonal bolt thread processing. Therefore, a clamping device for fastening bolt processing is proposed. Summary of the invention

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1: Please refer to Figure 1-Figure 5 The utility model provides a technical solution: a fastening bolt processing clamping device, comprising a vertical plate 1, a rotating drum 2 is rotatably penetrated on the outer surface of the vertical plate 1, a rotating disk 3 is fixedly connected to the outer surface of the rotating drum 2, four hexagonal grooves 4 arranged in a circumferential array are opened on the outer surface of the rotating disk 3, square grooves 5 are opened on the six sides of the hexagonal groove 4, a spring 6 is fixedly connected inside the square groove 5, a connecting plate 7 is fixedly connected to the other end of the spring 6, a clamping plate 8 is fixedly connected to the other end of the connecting plate 7, four mounting brackets 9 arranged in a circumferential array are fixedly connected to the outer surface of the rear side of the rotating disk 3, an electric push rod 10 is fixedly installed on the outer surface of the mounting bracket 9, and the output end of the electric push rod 10 is fixedly connected to the fixed cylinder 1 1. The rear outer surface of the connecting plate 7 is fixedly connected with a triangular plate 12. In this embodiment, the corresponding side of the head of the hexagonal bolt is placed in the hexagonal groove 4, and the electric push rod 10 is turned on. The electric push rod 10 drives the fixed cylinder 11 to move, so that the fixed cylinder 11 contacts the triangular plate 12. As the electric push rod 10 works, the electric push rod 10 drives the fixed cylinder 11 to squeeze the triangular plate 12, and the triangular plate 12 drives the connecting plate 7 to move the clamping plate 8 until the six clamping plates 8 clamp the six sides of the head of the hexagonal bolt, thereby fixing the hexagonal bolt, and then processing the hexagonal bolt, and then rotating the turntable 3 to rotate the next hexagonal bolt to be processed to the processing station for cyclic processing.

[0023] The bottom outer surface of the vertical plate 1 is connected to two symmetrically arranged fixing feet 13 by bolts, and the outer surfaces of the two fixing feet 13 are provided with fixing waist holes 14. In this embodiment, the fixing feet 13 are fixed to the processing machine by screwing the bolts into the fixing waist holes 14 as needed.

[0024] A C-shaped seat 15 is connected to the center of the bottom outer surface of the vertical plate 1 by bolts, and a threaded rod 16 is threaded through the bottom outer surface of the C-shaped seat 15, and an abutment plate 17 is provided on the top outer surface of the threaded rod 16. In this embodiment, the threaded rod 16 is rotated to drive the abutment plate 17 to move until the abutment plate 17 contacts the bottom of the side plate, and the device is clamped by the abutment plate 17 and the C-shaped seat 15, thereby completing the installation of the device.

[0025] A limit plate 18 is fixedly sleeved on the outer surface of the rear side of the rotating drum 2 located on the vertical plate 1, and a transverse plate is fixedly connected to the outer surface of the rear side of the rotating drum 2. Four limit holes 19 are opened on the outer surface of the limit plate 18 in a circular array. A latch 20 is movably inserted on the outer surface of the transverse plate, and the other end of the latch 20 is movably inserted in the corresponding limit hole 19. In this embodiment, after processing a hexagonal bolt, the latch 20 is removed so that the latch 20 is disengaged from the limit hole 19, the limit of the limit plate 18 is released, and the turntable 3 is rotated so that the turntable 3 rotates 90 degrees, and the next hexagonal bolt that has not been processed is processed.

[0026] The interior of the fixing tube 11 is a hollow conical shape that contracts inwardly. In this embodiment, the diameter of the fixing tube 11 decreases as it moves inwardly, so that when the fixing tube 11 contacts the triangular plate 12, the triangular plate 12 is driven to contract until the clamping plate 8 clamps the hexagonal bolt.

[0027] The outer surfaces of the C-shaped seat 15 and the abutment plate 17 are fixedly connected with anti-skid pads. In this embodiment, the anti-skid pads increase the friction between the abutment plate 17 and the C-shaped seat 15 and the surface of the processing machine, so that the device is stably fixed.

[0028] The outer surface of the clamping plate 8 is fixedly connected with a silicone pad. In this embodiment, the friction between the clamping plate 8 and the bolt is increased by providing the silicone pad, thereby reducing the possibility of the clamping plate 8 falling off during clamping.

[0029] Working principle: When the utility model is in use, the device is installed in a suitable position. During installation, the fixing foot 13 can be fixed on the processing machine by screwing the bolt into the fixing waist hole 14 as needed. At this time, the C-shaped seat 15 needs to be disassembled, or the fixing foot 13 can be disassembled, and the C-shaped seat 15 is aligned with the edge of the side plate of the processing machine, so that the top of the C-shaped seat 15 faces downward and fits the surface of the processing machine. The threaded rod 16 is rotated, and the threaded rod 16 drives the abutment plate 17 to move until the abutment plate 17 contacts the bottom of the side plate. The device is clamped by the abutment plate 17 and the C-shaped seat 15, thereby completing the installation of the device, and different installation methods can be selected according to actual needs, and then the hexagonal bolt is clamped. At this time, the corresponding edge of the head of the hexagonal bolt is placed on the hexagonal In the slot 4, the electric push rod 10 is turned on, and the electric push rod 10 drives the fixed cylinder 11 to move, so that the fixed cylinder 11 contacts the triangular plate 12. As the electric push rod 10 works, the electric push rod 10 drives the fixed cylinder 11 to squeeze the triangular plate 12, and the triangular plate 12 drives the connecting plate 7 to move the clamping plate 8 until the six clamping plates 8 clamp the six sides of the head of the hexagonal bolt, thereby fixing the hexagonal bolt, and then processing the hexagonal bolt. When the processing of the hexagonal bolt is completed, remove the pin 20, so that the pin 20 disengages from the limiting hole 19, release the limit of the limiting plate 18, rotate the turntable 3, so that the turntable 3 rotates 90 degrees, and processes the next hexagonal bolt that has not been processed, so that multiple hexagonal bolts can be fixed, thereby performing cyclic processing, and improving the processing efficiency of the hexagonal bolts.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
