[0023] 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.

[0024] like Figure 1-Figure 5 As shown, a spring hook drilling clamping mechanism comprises a mounting plate 1, on which a clamping member 2 is provided, the clamping member 2 comprises a movable block 22 and an adjusting block 25 for clamping the spring hook, a supporting block 28 for abutting against one end of the spring hook, a limiting plate 24 for limiting the vertical movement of the spring hook, and a swinging block 26 for abutting against the spring hook, the movable block 22 is movably mounted on the mounting plate 1, the limiting plate 24 is mounted on the movable block 22, and the supporting block 28 and the swinging block 26 are arranged on the mounting plate 1 opposite to each other.

[0025] The movement of the spring hook in the x direction is limited by positioning the abutment block 28 and the swing block 26, and the spring hook is clamped by the movable block 22 and the adjusting block 25 to limit the movement of the spring hook in the y direction. In addition, the movement of the spring hook in the z direction is achieved by the limiting plate 24, so that the spring hook is fixed by the matching connection of the movable block 22, the adjusting block 25, the abutment block 28, the limiting plate 24 and the swing block 26, and the processing of the movable block 22, the adjusting block 25, the abutment block 28, the limiting plate 24 and the swing block 26 is simpler, the processing accuracy requirement is low, and the processing cost is also lower.

[0026] Furthermore, the movable block 22 is provided with a first protrusion 23 , the adjusting block 25 is provided with a second protrusion 251 , and a gap for clamping the spring hook is formed between the first protrusion 23 and the second protrusion 251 .

[0027] A fixed block 21 is fixedly installed on the side of the mounting plate 1. The mounting plate 1 has a movable cavity 11 for the movable block 22 to slide. A first spring 27 is arranged between the fixed block 21 and the movable block 22. The first spring 27 always has a tendency to push the movable block 22 to move closer to the adjusting block 25. The other end of the movable block 22 is provided with a connecting rod 221 that passes through the mounting plate 1. The movable block 22 is driven to move by pushing the connecting rod 221.

[0028] Furthermore, a spring cavity 210 may be provided in both the fixed block 21 and the movable block 22 , and the first spring 27 may be better positioned and installed in the spring cavity 210 , thereby reducing the difficulty of assembly.

[0029] A rotating shaft 3 is provided on the swing block 26, and the rotating shaft 3 is fixedly mounted on the mounting plate 1. The swing block 26 swings around the axis of the rotating shaft 3. A limit block 4 for limiting the swing angle of the swing block 26 is also provided on the mounting plate 1. A mounting block 6 is installed on the mounting plate 1, and a positioning shaft 61 is installed in the mounting block 6. A second spring 5 is abutted between the positioning shaft 61 and the swing block 26. The second spring 5 always has a tendency to push the swing block 26 to swing to a side away from the mounting block 6. The swing block 26 is an "L"-shaped rod, so the long side and the short side of the swing block 26 are both limited by the limit block 4. A part of the swing block 26 is located outside the horizontal projection plane of the mounting plate 1, so it can better promote the movement of the swing block 26.

[0030] Furthermore, the connecting rod 221 and the swing block 26 are pushed by an external cylinder, thereby driving the swing block 26 to swing and the connecting rod 221 to move. In addition, the extreme position end point of the swing block 26 away from the fixed block 21 is at an equal distance in the y direction from the extreme position end point of the connecting rod 221 away from the fixed block 21. Therefore, when the cylinder contacts the swing block 26, it also contacts the connecting rod 221, thereby achieving the simultaneous driving of the swing block 26 and the sliding of the connecting rod 221.

[0031] Both the limit plate 24 and the adjustment block 25 are provided with a waist-shaped hole 250, and the limit plate 24 and the adjustment block 25 are fixedly installed on the mounting plate 1 through a connecting piece. The above-mentioned connecting piece is a bolt in the present application. In addition to the bolt, it can also be replaced by any connecting piece that can fix the limit plate 24 and the adjustment block 25 to the mounting plate 1, and the limit plate 24 and the adjustment block 25 can be adjustably fixedly installed on the mounting plate 1 along the waist-shaped hole 250, so that the adjustment block 25 and the limit plate 24 can be adjusted in the y direction according to spring hooks of different sizes and thicknesses, so that various spring hooks of different sizes or thicknesses can be adapted. By adjusting the position of the adjustment block 25, spring hooks of different thicknesses can be clamped, and by adjusting the position of the limit plate 24, spring hooks of different sizes can be clamped.

[0032] The limiting plate 24 includes a first limiting plate 241 and a second limiting plate 242 extending toward one side of the adjusting block 25, and there is a gap between the first limiting plate 241, the second limiting plate 242 and the upper surface of the mounting plate 1 for the spring hook to be placed in. The first limiting plate 241 and the second limiting plate 242 have different lengths. Since the shape of the spring hook is mostly gourd-shaped with one end larger than the other end, the first limiting plate 241 and the second limiting plate 242 have different lengths, so that a better effect can be achieved when fixing the spring hook.

[0033] A connecting block 252 is mounted on the mounting plate 1 , and an abutting rod 253 for positioning and mounting the adjusting block 25 is mounted on the connecting block 252 .

[0034] When in use, by pushing the swing block 26 and the connecting rod 221, the swing block 26 is driven to swing around the axis of the rotating shaft 3. At the same time, the connecting rod 221 drives the movable block 22 to move to the side close to the fixed block 21, so that the distance between the abutment block 28 and the swing block 26 becomes larger, and the gap between the first protrusion 23 and the second protrusion 251 becomes larger, so that the spring hook to be processed can be better placed. After loosening the swing block 26 and the connecting rod 221, the first spring 27 drives the movable block 22 to reset, so that the first protrusion 23 and the second protrusion 251 clamp the spring hook, and the second spring 5 drives the swing block 26 to reset, so that the swing block 26 abuts against the spring hook to be processed, and pushes the spring hook to be processed to abut against the abutment block 28, thereby achieving the function of fixing the spring hook to be processed.
