Description

Technical Field

[0001] The utility model relates to the technical field of roller repair, in particular to a roller surface finishing tool. Background Art

[0002] Nowadays, the installation of various equipment is becoming more and more compact, especially the installation of various rollers. The space between the roller surfaces is narrow. When a roller surface is worn in actual production, if it is not repaired in time, the strip steel will be seriously scratched, resulting in the scrapping of the finished product and excessive damage to subsequent equipment.

[0003] In the related art, the roller surface is usually ground until the roller surface diameter is consistent. Each time the roller surface is ground, if there is damage such as grooves on the roller surface, the grinding and repair efficiency is low. Most of the time, the old roller body is returned to the factory for repair after replacing the new one, which affects the working cycle. Therefore, the existing technology needs to be improved.

[0006] The roller surface can be cut by the cutter head and finely ground by the grinding belt to ensure the roller surface is flat and uniform.

[0007] A driving motor is installed on the surface of the base, and the first slide and the driving motor are both equipped with a four-jaw chuck, and the driving motor drives the roller to rotate, so that the cutter head can cut the roller;

[0008] A translation driving structure is installed on the side of the base, and is used to push the second slide to move, so as to realize the movement and cutting of the cutter head.

[0009] Furthermore, a tool seat is installed on the piston rod of the electric cylinder, the tool head is connected to the tool seat, the upper end of the pull rod is fixedly connected to a clamp seat, and both ends of the grinding belt are connected to the corresponding clamp seats. The tool seat is provided to facilitate the replacement of the tool head, and the clamp seat can replace the grinding belt.

[0010] Furthermore, the translation drive structure includes a moving motor, the moving motor is connected to a screw, the screw is transmission-connected to a nut, the second slide is connected to the nut, and the moving motor, screw and nut constitute a linear moving structure of a ball screw to ensure smooth and precise movement of the cutter head.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) The roller can be clamped by two four-jaw chucks. When cutting the roller surface, the drive motor drives the roller to rotate, the electric cylinder controls the cutter head to cut the rotating roller, and the mobile motor controls the translation of the cutter head. The roller surface can be fully cut to ensure that the roller surface diameter is consistent. The roller with grooves can be repaired faster.

[0013] (2) The roller surface can be fine-ground by the grinding belt to ensure that the roller surface is smoother and less prone to excessive damage when put into use again. The mobile motor can also control the left and right movement of the grinding belt to fully fine-ground the roller surface.

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.

[0020] Example:

[0021] See also Figure 1-4 The utility model provides a technical solution: a roller surface finishing tool, comprising a base 1, two guide rails 2 are installed on the base 1, a first slide 3 and two second slides 6 are slidably connected on the guide rails 2, an electric cylinder 10 and a cylinder shell 7 are respectively installed on the two second slides 6, a cutter head 17 is installed on the electric cylinder 10, a pull rod 18 is installed inside the cylinder shell 7, a spring 19 is installed on the pull rod 18, and the spring 19 is in contact with the cylinder shell 7, and a grinding belt 9 is installed on the upper end of the pull rod 18;

[0022] like Figure 3 As shown, the lower end of the spring 19 presses against the lower end side of the pull rod 18, so that the pull rod 18 can smoothly pull down the grinding belt 9, and the pull rod 18 can move up and down to ensure that the grinding belt 9 can finely grind rollers of different sizes. The electric cylinder 10 is used to control the distance between the cutter head 17 and the roller, so that rollers of different sizes can be cut and the cutting accuracy can be precisely controlled;

[0023] A driving motor 5, wherein the driving motor 5 is installed on the surface of the base 1, and the first slide 3 and the driving motor 5 are both installed with a four-jaw chuck 4, and the four-jaw chuck 4 can be used to accurately clamp the roller, and the first slide 3 can slide on the guide rail 2, and rollers of different lengths can be clamped;

[0024] A translation drive structure is installed on the side of the base 1, and is used to push the second slide 6 to move, so that the cutter head 17 and the grinding belt 9 can slide, which is convenient for comprehensive grinding of the roller.

[0025] In this embodiment, if Figure 2 As shown, a tool holder 16 is installed on the piston rod of the electric cylinder 10, and the tool head 17 is connected to the tool holder 16. The tool head 17 is detachably assembled with the tool holder 16. After the tool head 17 is worn to the point of being unusable, it is convenient to replace the tool head 17.

[0026] In this embodiment, if Figure 1 As shown, the upper end of the pull rod 18 is fixedly connected to a clamp seat 8, and both ends of the grinding belt 9 are connected to the corresponding clamp seats 8. The two ends of the grinding belt 9 can be detached from the clamp seat 8, so that when the grinding belt 9 needs to be replaced, it is convenient to replace a new grinding belt 9.
