Description

Technical Field

[0001] This utility model relates to the field of gasket processing technology, and in particular to a rounding mechanism for gasket processing. Background Technology

[0002] A gasket is a mechanical seal between two objects, typically used to prevent leakage caused by pressure, corrosion, and the natural thermal expansion and contraction of piping. Since machined surfaces are never perfect, gaskets fill in these irregularities. Gaskets are usually made of sheet materials such as paper, rubber, silicone rubber, metal, cork, felt, neoprene, nitrile rubber, fiberglass, or plastic polymers. Gaskets for specific applications may contain asbestos.

[0003] A gasket is a perforation in a thin sheet of paper, typically used for distributing loads to fasteners. Other uses include as spacers, springs, wear pads, pre-display devices, and locking mechanisms. Rubber gaskets are also used in faucets to cut off the flow of liquids or gases. Rubber or silicone gaskets can also be used to reduce fan vibration. Typically, the outer diameter of a gasket is about twice its inner diameter.

[0004] When processing gaskets, the wear of the cutting tools varies depending on the material of the gasket. After the cutting tools wear out, they need to be replaced. However, it is generally inconvenient to replace the tools in existing circular cutting machines, which makes the circular cutting machines inefficient when processing gaskets of different materials. Utility Model Content

[0008] A drive motor is provided at the top of the horizontal end of the L-shaped frame, and a mounting plate is fixedly provided at the output end of the drive motor. A cutting mechanism is provided on the side of the mounting plate away from the drive motor, and a lateral mounting block is provided on one side of the cutting mechanism.

[0009] Furthermore, in a preferred configuration, a lifting limit rod is provided at the horizontal end of the lateral mounting block, and the lifting limit rod is U-shaped, with a spring provided between the inner horizontal end of the lifting limit rod and the lateral mounting block.

[0010] Furthermore, in a preferred configuration, the bottom of the lateral mounting block has a mounting cavity, and the vertical end of the lifting limit rod extends through one side of the lateral mounting block to the inner wall of the mounting cavity.

[0011] Furthermore, in a preferred configuration, a knife handle is provided inside the mounting cavity, a cutting tool is provided at the bottom of the knife handle, and a limiting hole is provided on the side of the knife handle, with the limiting hole being compatible with the lifting limiting rod.

[0012] In addition, a preferred structure is that a mounting base is provided on the other side of the top of the worktable, and a processing fixture is provided on the top of the mounting base, with the middle of the processing fixture located directly below the drive motor.

[0013] In addition, a preferred structure is that a main controller is provided on one side of the worktable, and the dual-axis drive round cutting mechanism and the drive motor are connected to the main controller via electrical signals.

[0014] The beneficial effects of this utility model are as follows: First, the cutting mechanism at the bottom of the double-axis drive cutting mechanism at the top of the worktable cuts the pads on the processing fixture into circles. Then, the lifting limit rod on the side of the cutting mechanism and the spring make it easy to replace the cutting tool when processing pads of different materials. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A round cutting mechanism for gasket processing includes a worktable 1, a dual-axis driven round cutting mechanism 2 is provided on the top side of the worktable 1, and an L-shaped frame 5 is provided at the bottom of the end of the dual-axis round cutting mechanism 2.

[0022] The top of the horizontal end of the L-shaped frame 5 is provided with a drive motor 4, and the output end of the drive motor 4 is fixedly provided with a mounting plate 9. A cutting mechanism 3 is provided on the side of the mounting plate 9 away from the drive motor 4, and a lateral mounting block 31 is provided on one side of the cutting mechanism 3.

[0023] The lateral mounting block 31 is provided with a lifting limit rod 32 at its horizontal end. The lifting limit rod 32 is U-shaped, and a spring 33 is provided between the inner horizontal end of the lifting limit rod 32 and the lateral mounting block 31.

[0024] Meanwhile, the bottom of the lateral mounting block 31 is provided with a mounting cavity 37, and the vertical end of the lifting limit rod 32 penetrates one side of the lateral mounting block 31 to the inner wall of the mounting cavity 37.

[0025] In addition, a knife handle 34 is provided inside the mounting cavity 37, and a cutting knife 36 is provided at the bottom of the knife handle 34. A limiting hole 35 is provided on the side of the knife handle 34, and the limiting hole 35 is compatible with the lifting limiting rod 32.

[0026] Furthermore, a mounting base 6 is provided on the other side of the top of the worktable 1, and a machining fixture 7 is provided on the top of the mounting base 6, with the middle of the machining fixture 7 located directly below the drive motor 4.

[0027] Furthermore, a main controller 8 is provided on one side of the workbench 1, and the dual-axis drive round cutting mechanism 2 and the drive motor 4 are connected to the main controller 8 via electrical signals.

[0028] In this embodiment, when processing different gaskets, the gaskets need to be fixed on the processing fixture 7 for processing. When the gasket is placed on the processing fixture 7 set on the top of the worktable 1, the dual-axis drive round cutting mechanism 2 is driven by the main controller 8 for positioning processing, and the rotation of the drive motor 4 drives the cutting mechanism 3 to perform round cutting processing on the gasket on the processing fixture 7.

[0029] After multiple processing of the gasket, the cutting tool 36 will wear out, resulting in low efficiency of subsequent processing and difficulty in guaranteeing the size and roundness. Therefore, the cutting tool 36 on the cutting mechanism 3 needs to be replaced. First, ensure that the processing equipment is powered off. Hold the thicker part of the cutting tool 36 with one hand, and then pull the lifting limit rod 32 with the other hand. When the end of the lifting limit rod 32 is disengaged from the interior of the mounting cavity 37, the tool holder 34 inside the mounting cavity 37 will be disengaged from the mounting cavity 37. Then the cutting tool 36 can be removed.

[0030] When replacing the cutting tool, first insert the handle 34 of the new cutting tool 36 into the mounting cavity 37, and align the side of the mounting cavity 37 with the limiting hole 35 with the side of the lifting limiting rod 32. Then, pull the limiting rod 32 and use the restoring force of the inner spring 33 to insert the lifting limiting rod 32 into the mounting cavity 37, so that it coincides with the limiting hole 35 on the handle 34, so that the new cutting tool 36 is limited inside the cutting mechanism 3, making it easy to replace the cutting tool 36.

[0031] In this utility model, the cutting mechanism at the bottom of the double-axis driving cutting mechanism 2 at the top of the workbench 1 first cuts the pads on the processing fixture 7 into circles. Then, the lifting limit rod 32 on the side of the cutting mechanism 3 and the spring 33 work together to make it easy to change the cutting tool 36 when processing pads of different materials.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
