Description

Technical Field

[0001] This application relates to the technical field of roll fixtures, and particularly to a clamping tooling for roll marking. Background Art

[0002] As Figure 1 shown in the roll 5, before leaving the factory, it needs to be marked, and the model and specific parameters are laser marked on the roll surface.

[0003] In the prior art, generally, the roll is manually placed under the marking machine for marking, and after marking, it still needs to be manually taken away. The manual placement has a large labor intensity and low production efficiency.

[0004] Therefore, it is urgent to develop a clamping tooling that can be used with the production line to achieve fully automated marking. Utility Model Content

[0005] The purpose of this application is to provide a clamping tooling for roll marking to solve the problems raised in the above background art.

[0006] To achieve the above purpose, this application provides a clamping tooling for roll marking, which adopts the following technical solutions:

[0007] A clamping tooling for roll marking includes a workbench and a clamping mechanism installed on the workbench. The clamping mechanism includes a servo motor, a turntable, and a plurality of clamping components evenly arranged on the periphery of the turntable. The turntable is rotatably installed on the workbench, and the servo motor is fixed at the bottom of the workbench and is used to drive the turntable to rotate;

[0008] The clamping component includes a connecting rod, a positioning arc block, a double-headed cylinder, and two rocker arms. The connecting rod is fixed on the side wall of the turntable, the positioning arc block is fixed at the end of the connecting rod, the two rocker arms are symmetrically hinged on both sides of the positioning arc block, a roller is rotatably connected to the rocker arm, a slider is slidably installed on the connecting rod along the length direction, the double-headed cylinder is fixed on the slider, and a connecting frame is fixed at the end of the output shaft of the double-headed cylinder. One end of the rocker arm is hinged on the connecting frame.

[0009] Preferably, the turntable is arranged near the edge of the workbench. The surface of the workbench is a smooth surface, and the marking machine is installed on the workbench.

[0010] By adopting the above technical solutions, the surface of the workbench is used as the loading area and the marking working area, and the side of the workbench is used for unloading.

[0011] Preferably, in order to improve the clamping effect, the inner wall of the positioning arc block is wrapped with a rubber pad, and the surface of the roller is wrapped with a rubber anti-slip layer.

[0012] The distance between the two hinge points on the rocker arm accounts for one-third of the total length of the rocker arm.

[0013] In summary, the present application includes at least one of the following beneficial technical effects: The clamping tooling for roll marking has a simple structure, is easy to manufacture, and can be used in conjunction with the production line. After automatic feeding or manual feeding, the double-headed cylinder in the clamping assembly extends to push the rocker arms on both sides to drive the rollers to press the roll tightly against the positioning arc block. The turntable drives it to rotate under the marking machine for marking. After the marking is completed, the turntable drives it to rotate to the outside of the workbench again. The double-headed cylinder shortens to drive the rocker arms on both sides away from the roll. After the roll loses the clamping force, it drops under its own gravity, realizing automatic blanking and greatly improving production efficiency. Description of the Drawings

[0018] The following further elaborates on the present application in conjunction with the attached Figure 2-3 drawings.

[0019] An embodiment of the present application discloses a clamping tooling for roll marking. Referring to Figure 2-3 , it includes a workbench 1 and a clamping mechanism installed on the workbench 1. The clamping mechanism includes a servo motor 2, a turntable 3, and four clamping assemblies 4 evenly arranged on the periphery of the turntable 3. The turntable 3 is rotatably installed on the workbench 1. The servo motor 2 is fixed to the bottom of the workbench 1 and is used to drive the turntable 3 to rotate. The turntable 3 is arranged near the edge of the workbench 1. The surface of the workbench 1 is a smooth surface, and a marking machine is installed on the workbench 1;

[0020] The clamping assembly 4 includes a connecting rod 41, a positioning arc-shaped block 42, a double-headed cylinder 43 and two rocker arms 44. The connecting rod 41 is fixed on the side wall of the turntable 3. The positioning arc-shaped block 42 is fixed at the end of the connecting rod 41. A rubber pad is wrapped on the inner wall of the positioning arc-shaped block 42. The two rocker arms 44 are symmetrically and hingedly arranged on both sides of the positioning arc-shaped block 42. A roller 45 is rotatably connected to the rocker arm 44. A slider 46 is slidably installed on the connecting rod 41 along the length direction. The double-headed cylinder 43 is fixed on the slider 46. A connecting frame 47 is fixed at the end of the output shaft of the double-headed cylinder 43. One end of the rocker arm 44 is hinged on the connecting frame 47.

[0021] To improve the clamping effect, a rubber anti-slip layer is wrapped on the surface of the roller 45.

[0022] Referring to Figure 2 and Figure 3 In order to enable the rocker arm 44 to rotate flexibly and have a strong clamping ability, the distance between the two hinge points on the rocker arm 44 accounts for one-third of the total length of the rocker arm 44.

[0023] The implementation principle of a clamping tool for roll marking in an embodiment of the present application is as follows:

[0024] This clamping tool can be matched in the production line. A feeding device and a conveyor belt are respectively arranged on both sides of the workbench 1. The conveyor belt is arranged on the side close to the turntable, and the feeding device is arranged on the side far from the turntable. The feeding device uses a conventional cylinder and a feeding conveyor belt to push the roll to the positioning arc-shaped block 42 (manual feeding is also possible. The operator only needs to place the roll beside the positioning arc block, and subsequent automatic blanking will be carried out).

[0025] After the roll is pushed to the positioning arc-shaped block 42, the double-headed cylinder 43 extends to push the rocker arms 44 on both sides to rotate. The rollers 45 on both sides touch the roll and push the roll against the positioning arc-shaped block 42. The two rollers 45 and the positioning arc-shaped block 42 can realize automatic centering clamping of the roll. After clamping is completed, the servo motor 2 drives the turntable 3 to rotate one station, and the marking machine marks the roll. After marking is completed, the servo motor 2 drives the turntable 3 to rotate one more station. At this time, the roll hovers outside the workbench 1. The double-headed cylinder 43 shortens to drive the rocker arms 44 on both sides away from the roll. After the roll loses the clamping force, it drops under its own gravity, and automatic blanking can be realized, greatly improving the production efficiency.

[0026] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
