Description

Technical Field

[0001] The utility model relates to the technical field of clamping claws, in particular to a connecting rod material pulling claw. Background Art

[0002] Clamping jaws are essential components for clamping and positioning workpieces during machining. The jaws are typically evenly distributed on the chuck, with cross gears controlling the jaws' size to allow them to secure the workpiece.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Reference Figure 1-8 A connecting rod pulling claw comprises a wide claw pulling component 2, which is symmetrically arranged. A narrow claw pulling component 6 is symmetrically arranged on one side of the wide claw pulling component 2. A pulling component 7 is installed on the top of the wide claw pulling component 2 and the narrow claw pulling component 6. The pulling component 7 is used to push the wide claw component 1 and the narrow claw component 5 on the front side to move.

[0030] In addition, the material pulling assembly 7 includes a mounting base 8 , on which a cylinder 10 is provided. A transmission mechanism 9 is provided on the mounting base 8 on one side of the cylinder 10 , and the cylinder 10 is used to drive the transmission mechanism 9 .

[0031] Moreover, the transmission mechanism 9 includes a cylinder connecting block 91, on which a first connecting rod 92 is symmetrically rotatably arranged, and the other end of the first connecting rod 92 away from the cylinder connecting block 91 is rotatably connected to a second connecting rod 93 and a third connecting rod 94, one end of the second connecting rod 93 and one end of the third connecting rod 94 are both rotatably connected to the first connecting rod 92, and the other end of the third connecting rod 94 away from the second connecting rod 93 is rotatably connected to a connecting block 96, which is installed on the third connecting rod 94 on both sides, and the wide claw assembly 1 is installed on the connecting block 96 on the wide claw pulling assembly 2, and the narrow claw assembly 5 is installed on the connecting block 96 on the narrow claw pulling assembly 6. Transmission is performed through the transmission mechanism 9, so that a smaller cylinder 10 can be set, which can save costs.

[0032] In addition, a fixed support 95 is rotatably provided at the other end of the second connecting rod 93 away from the third connecting rod 94 . The fixed support 95 is mounted on the mounting seat 8 . The fixed support 95 is used to fix the first connecting rod 92 and the second connecting rod 93 .

[0033] Moreover, the wide jaw assembly 1 includes a long pad 11, a toothed long pad 12 is installed on one side wall of the long pad 11, and a first guide shaft 13 is symmetrically arranged on the other side wall of the long pad 11 away from the toothed long pad 12. The toothed long pad 12 can prevent the workpiece from slipping.

[0034] In addition, the wide jaw pulling assembly 2 includes a wide jaw 21, a pulling assembly 7 is installed on the upper surface of the wide jaw 21, a long roller 22 is rotatably provided on the wide jaw 21, and a pad 23 is vertically installed at the bottom of the wide jaw 21. The long roller 22 is located below the wide jaw assembly 1, and the pad 23 can increase the height of the wide jaw 21, so that the wide jaw assembly 1 can be higher than the narrow jaw assembly 5.

[0035] At the same time, the narrow jaw assembly 5 includes a narrow pad 51, a beveled pad 52 is installed on one side of the narrow pad 51, and a second guide shaft 53 is symmetrically arranged on the side wall of the narrow pad 51 away from the beveled pad 52. The beveled pad 52 can prevent the workpiece from slipping.

[0036] In addition, the narrow jaw pulling assembly 6 includes a narrow jaw 61, and a pulling assembly 7 is installed on the upper surface of the narrow jaw 61. A short roller 62 is rotatably provided on the narrow jaw 61. The short roller 62 is located below the narrow jaw assembly 5. The short roller 62 is convenient for cooperating with the workpiece to roll with it, thereby realizing the displacement of the workpiece.

[0037] At the same time, guide holes 82 are symmetrically opened on the blocks on both sides of the transmission mechanism 9 on the upper surface of the mounting seat 8. The first guide shaft 13 and the second guide shaft 53 are arranged to move at the guide holes 82. A through hole 81 is opened in the middle of the block on the mounting seat 8 on one side of the transmission mechanism 9. The piston rod on the output end of the cylinder 10 is located at the through hole 81. The cylinder 10 can effectively push the transmission mechanism 9 to move, thereby pushing the connecting block 96 to move.

[0038] Moreover, the piston rod of the cylinder 10 is connected to the cylinder connecting block 91, and mounting holes 83 are symmetrically opened on both sides of the through hole 81 on the mounting seat 8. The fixed support 95 is installed at the mounting hole 83, and the through hole 81 is used for the piston rod of the cylinder 10 to move.

[0039] At the same time, the outer cover of the pulling component 7 above the narrow jaw pulling component 6 is provided with a second sheet metal protective cover 4, and the outer cover of the pulling component 7 above the wide jaw pulling component 2 is provided with a first sheet metal protective cover 3. The first sheet metal protective cover 3 and the second sheet metal protective cover 4 can play an effective dust-proof role.

[0040] In this embodiment, when clamping the workpiece, a pair of wide jaw pulling assemblies 2 and a pair of narrow jaw pulling assemblies 6 can be installed on the chuck. When clamping the workpiece, each cylinder 10 synchronously extends the piston rod at its output end, and then pushes each cylinder connecting block 91, driving the first connecting rod 92 on both sides to rotate, and then makes the second connecting rod 93 and the third connecting rod 94 on both sides move, thereby pushing out the connecting block 96, so that the wide jaw assembly 1 and the narrow jaw assembly 5 can be extended synchronously.

[0041] After the wide jaw assembly 1 and the narrow jaw assembly 5 are extended, the long toothed pad 12 and the oblique toothed pad 52 can synchronously clamp the workpiece.

[0042] Moreover, the transmission mechanism 9 makes the cylinder 10 free from stress, because the cylinder 10 needs to bear a large reaction force when the piston rod pushes straight, so that the clamping stability and reliability can be guaranteed.

[0043] In the present invention, the pulling assembly 7 can be installed on the wide jaw pulling assembly 2 and the narrow jaw pulling assembly 6 at the same time, and in conjunction with the wide jaw assembly 1 and the narrow jaw assembly 5, the four surfaces can clamp the workpiece together, so that the workpiece is not easy to slip, ensuring the clamping stability and reliability, and the transmission mechanism 9 is driven by the cylinder 10, so that a smaller cylinder can be used, saving costs, and reducing the installation height, ensuring the clamping stability and reliability, and the transmission mechanism 9 can decompose and bear force, so that the cylinder 10 is not subjected to force, ensuring the clamping stability and reliability.

[0044] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
