Description

Technical Field

[0001] The utility model relates to the technical field of special equipment for dynamic equipment sealing, and particularly relates to a gasket rapid cutting device. Background Art

[0002] At present, common sealing gaskets such as PTFE gaskets or asbestos gaskets on the market are usually sold in the form of finished products, which leads to the problems of high price and long supply cycle. During the maintenance process, if there are no ready-made spare parts, workers often need to use scissors for cutting, but this method has many deficiencies. The size of the cut gasket may not be precise enough, and the roundness is also difficult to guarantee. Moreover, narrow gaskets are more likely to break during the cutting process. These problems not only bring a lot of inconvenience to the maintenance work, but also prolong the maintenance time, thereby increasing the maintenance cost.

[0003] A gasket cutting tool disclosed in Chinese Patent CN218170561U has a scale provided at the upper end of a magnetic bracket. The scale is connected to the magnetic bracket through a bearing and is positioned by a circlip and a shaft shoulder; a magnetic knob is provided at the lower end of the magnetic bracket to adjust the opening and closing of the magnetism; a tool holder is provided on the scale. The scale passes through a sliding hole at the upper end of the tool holder, and the tool holder is fixed by a locking screw at the upper end of the tool holder; a hob is fixedly provided at the lower end of the tool holder.

[0004] PTFE gaskets or asbestos gaskets are usually of annular structure. When cutting PTFE gaskets or asbestos gaskets with the above cutting tool, it is necessary to first cut the outer diameter of the gasket by moving the tool holder on the scale, and then move the tool holder to cut the inner diameter of the gasket with the hob. Cutting one gasket requires two operations, which is time-consuming and laborious, and the working efficiency is low; when moving the tool holder, it is necessary to remove the magnetic bracket to prevent the hob from scratching the gasket to be cut. After the tool holder is moved to the predetermined cutting position, the magnetic bracket needs to be repositioned to ensure that its positions before and after are consistent. However, relying solely on the manual operation of the staff for positioning, it is often difficult to ensure that the position of the magnetic bracket does not deviate during the two operations. This inaccuracy of the position may cause the centers of the inner and outer diameters of the cut gasket not to coincide, thereby having an adverse effect on the quality of the gasket. Summary of the Utility Model

[0005] In order to solve the deficiencies of the prior art, improve the cutting accuracy and efficiency of gaskets, and reduce the errors caused by manual operation, the utility model provides a gasket rapid cutting device.

[0006] To achieve the above object, the technical solution of the present utility model is: A rapid gasket cutting device, including a magnetic bracket, a first scale is rotatably connected to the top of the magnetic bracket, a first tool holder that can slide along the first scale is arranged on the first scale, a first hob is arranged at the bottom of the first tool holder, a second scale is fixedly connected to one side of the first tool holder, a second tool holder that can slide along the second scale is arranged on the second scale, and a second hob is arranged at the bottom of the second tool holder.

[0007] Further, a first locking screw for fixing the first tool holder is arranged at the top of the first tool holder, and a second locking screw for fixing the second tool holder is arranged at the top of the second tool holder.

[0008] Further, the first scale and the second scale are located on the same vertical plane.

[0009] Further, a magnetic knob is arranged on the magnetic bracket, and the magnetic knob controls the opening or closing of the magnetism of the magnetic bracket.

[0010] Further, a plurality of bumps are arranged at the bottom of the magnetic bracket.

[0011] Further, the bumps are in an inverted conical structure.

[0012] Further, a bearing is arranged at the connection between the magnetic bracket and the first scale, and a snap ring is arranged at the top of the bearing.

[0013] Further, the number of the bearings is two, and the bearings are rolling bearings.

[0014] Further, both the first scale and the second scale are in a square columnar structure.

[0015] The beneficial effects achieved by the present utility model are:

[0021] In order to better understand the purpose, structure and function of the present utility model, the following will further describe in detail a quick gasket cutting device of the present utility model with reference to the attached drawings.

[0022] As Figures 1 to 2 shown, a quick gasket cutting device includes a magnetic support 1. The top of the magnetic support 1 is rotatably connected with a first scale 3. A bearing 11 is arranged at the connection between the magnetic support 1 and the first scale 3. The number of bearings 11 is two. The bearings 11 are rolling bearings. A snap ring 12 is arranged above the uppermost bearing 11. The snap ring 12 clamps the bearing 11 to prevent the bearing 11 from moving up and down. A first tool holder 4 that can move along the first scale 3 is arranged on the first scale 3. The first scale 3 is of a square column structure. The square column structure can prevent the first tool holder 4 from rotating around the first scale 3. A first locking screw 5 for fixing the first tool holder 4 is arranged on the first tool holder 4. A first hob 6 is arranged at the bottom of the first tool holder 4. The first hob 6 is used for cutting the inner diameter of the gasket. A second scale 7 is fixedly arranged on one side of the first tool holder 4. The second scale 7 and the first scale 3 are located in the same vertical plane. A second tool holder 8 that can move along the second scale 7 is arranged on the second scale 7. The second scale 7 is of a square column structure. The square column structure can prevent the second tool holder 8 from rotating around the second scale 7. A second locking screw 9 for fixing the second tool holder 8 is arranged on the second tool holder 8. A second hob 10 is arranged at the bottom of the second tool holder 8. The second hob 10 is used for cutting the outer diameter of the gasket. Among them, both the first hob 6 and the second hob 10 are rotatable tool heads, which can improve the cutting speed and quality. The cut gasket has a high roundness and no burrs.

[0023] A magnetic knob 2 is arranged on the magnetic support 1. The magnetic knob 2 controls the opening or closing of the magnetism of the magnetic support 1. When the magnetic knob 2 is rotated to the triangle, it is magnetic. When rotated to the circle, it is non-magnetic. By adjusting the magnetic support 1 to be magnetic, the magnetic support 1 can be adsorbed to an iron workbench, which is convenient for fixing the magnetic support 1. A plurality of convex blocks are arranged at the bottom of the magnetic support 1. The convex blocks are of an inverted conical structure as a whole. The convex blocks can increase the friction between the magnetic support 1 and the gasket and prevent the gasket from moving randomly during cutting.

[0024] In use, according to the length of the inner diameter of the gasket to be replaced, adjust the position of the first tool rest 4 on the first scale 3 so that the distance between the first hob 6 and the center of the magnetic support 1 is equal to the inner diameter of the gasket. Rotate the first locking screw 5 to fix the first tool rest 4. According to the length of the outer diameter of the gasket to be replaced, adjust the position of the second tool rest 8 on the second scale 7 so that the distance between the second hob 10 and the center of the magnetic support 1 is equal to the outer diameter of the gasket. Rotate the second locking screw 9 to fix the second tool rest 8. Lay the gasket base material flat on the iron workbench, make the bottom of the magnetic support 1 stick to the gasket base material, rotate the magnetic knob 2 to turn on the magnetism of the magnetic support 1, and fix the magnetic support 1 and the gasket base material on the iron workbench. Rotate the first scale 3 to drive the first hob 6 and the second hob 10 to cut the gasket base material. After cutting is completed, turn off the magnetism of the magnetic support 1, remove the magnetic support 1, and take out the cut gasket.
