Description

Technical Field

[0001] The utility model relates to the technical field of chamfering wheels, in particular to a chamfering wheel with an anti-loosening structure. Background Art

[0002] A chamfering wheel is a tool used to chamfer the edge of a workpiece. It is usually made of metal or carbide and has a special chamfer shape. The main function of a chamfering wheel is to create chamfers on the edge of the workpiece in order to provide a smoother and safer surface. Chamfering can eliminate sharp edges on the edge of the workpiece, reduce the risk of cutting the workpiece, and improve its appearance quality. Chamfering wheels are widely used in metal processing, machinery manufacturing, aerospace and other fields.

[0003] When the chamfering wheels currently on the market are used, the cutter teeth installed on the surface of the chamfering wheel are generally fixed directly by a single screw. The installation between the cutter teeth and the chamfering wheel is not firm enough. After the chamfering wheel is used for a long time, the cutter teeth on the surface of the chamfering wheel are easy to loosen. Therefore, we propose a chamfering wheel with an anti-loosening structure. Utility Model Content

[0004] The purpose of the utility model is to provide a chamfering wheel with an anti-loosening structure to solve the problems raised by the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a chamfering wheel with an anti-loosening structure, comprising a chamfering wheel body, a mounting shaft and cutter teeth, a mounting shaft is welded to the lower middle part of the chamfering wheel body, and cutter teeth are arranged on the surface edge of the chamfering wheel body. A limiting assembly is arranged between the cutter teeth and the chamfering wheel body, and the limiting assembly comprises an active cavity, a guide groove, an mounting groove, a mounting block, a docking hole, a docking pin, a guide block, a threaded rod and a hexagonal block. The active cavity is provided below the chamfering wheel body, and a guide groove is provided above the chamfering wheel body near the active cavity, mounting grooves are provided above both sides of the chamfering wheel body near the active cavity, and mounting blocks are inserted into the mounting grooves.

[0006] Preferably, the upper end of the mounting block is connected to the inner wall of the cutter tooth, and a docking hole is provided on one side of the mounting block.

[0007] Preferably, docking pins are provided on both sides of the movable cavity, the docking pins penetrate the chamfering wheel body and are inserted into the docking hole, and the top end of the docking pins is connected to a guide block.

[0008] Preferably, the guide block is docked inside the guide groove, and a threaded rod penetrates the bottom of the two docking pins.

[0009] Preferably, the threaded rod is connected to both sides of the inner wall of the movable cavity through a bearing seat, and a hexagonal block is welded to the outer side of the middle part of the threaded rod.

[0010] Preferably, oil filling ports are provided on both sides of the installation shaft, and an oil storage cavity is provided below the installation shaft near the oil filling ports, and a lubrication channel is provided below the installation shaft near the oil storage cavity.

[0011] Preferably, the top end of the lubrication channel is connected to the bottom of the oil storage cavity, and a connecting block is provided on the outer side of the oil filling port.

[0012] Preferably, the inner wall of the connecting block is connected with a sealing seat, and the sealing seat is butt-plugged inside the oil filling port.

[0013] Compared with the prior art, the beneficial effect of the utility model is that the chamfering wheel with an anti-loosening structure is reinforced and assembled between the cutter teeth and the chamfering wheel body through a limit assembly to prevent the cutter teeth from shaking during use, so that the chamfering wheel has an anti-loosening structure, and oil filling ports are set on both sides of the mounting shaft to facilitate oil lubrication of the inner wall of the mounting shaft, thereby facilitating regular lubrication of the chamfering wheel.

[0014] 1. The chamfering wheel with an anti-loosening structure first inserts the mounting block at the bottom of the cutter teeth into the mounting groove on the chamfering wheel body to the limit position, then sets the matching hexagonal wrench on the outside of the hexagonal block and rotates the hexagonal block. The rotating hexagonal block drives the connected threaded rod to rotate synchronously. With the rotation of the threaded rod, the two docking pins set on the outside will move to both sides along the active cavity at the same time until the docking pins penetrate the chamfering wheel body and are plugged into the docking hole. The cutter teeth and the chamfering wheel body are reinforced and assembled by the set limit assembly to prevent the cutter teeth from shaking during use, so that the chamfering wheel has an anti-loosening structure;

[0015] 2. The chamfering wheel with an anti-loosening structure first pulls the connecting block and the sealing seat outward, and the oil filling port squeezes the movable rubber sealing seat until the connecting block is removed, and then the lubricating oil is injected from the opening of the oil filling port. The injected lubricating oil flows into the interior of the oil storage cavity, and flows from the lubrication channel through the oil storage cavity to the inner wall of the mounting shaft. Subsequently, the sealing seat and the oil filling port are docked and installed, and the opening of the oil filling port is sealed. By arranging the oil filling ports on both sides of the mounting shaft, the inner wall of the mounting shaft can be easily lubricated with oil, thereby facilitating regular lubrication of the chamfering wheel.
