Technical Field

[0001] The utility model relates to the technical field of end face chamfering tools, in particular to a chamfering machine. Background Art

[0002] At present, the chamfering machine used for end face chamfering mainly includes a chamfering machine body, a cutting tool is installed at the head of the chamfering machine body, and a power device for driving the cutting tool is installed in the chamfering machine body. When in use, the operator turns on the power device, holds the tail of the chamfering machine body, and controls the cutting tool to chamfer the end face to be processed.

[0003] Chinese utility model patent: Publication number CN202479617U discloses a chamfering machine, including a chamfering machine body, a cutting tool is installed at the head of the chamfering machine body, a power device for driving the cutting tool is installed in the chamfering machine body, a base plate is connected to the head of the chamfering machine body, the cutting tool is installed in the base plate, guide plates and angle adjustment devices are respectively provided on both sides of the cutting tool, the guide plate is fixed on the base plate, a plurality of roller bearings are embedded on the guide plate, and the rolling direction of the roller bearing is consistent with the movement direction of the reciprocating linear movement of the chamfering machine during chamfering.

[0004] In the existing technology, when CN202479617U is in use, a guide block and an angle adjustment device are respectively provided on both sides of the cutting tool. Therefore, when in use, the guide block can fit and slide against the end surface to be processed, which is not only convenient for the operator to chamfer and save time and effort, but also can ensure the chamfering accuracy by adjusting the angle adjustment device on the other side. At the same time, a number of roller bearings are embedded in the guide block, and the rolling direction of the roller bearings is consistent with the direction of reciprocating linear movement of the chamfering machine during chamfering. Therefore, the friction force when the guide block fits and slides against the end surface to be processed can be greatly reduced, thereby saving time and effort for the operator when chamfering.

[0005] However, it is difficult for the device in the prior art to perform rounded corner chamfering when performing end face chamfering operation, so a chamfering machine is needed to perform rounded corner chamfering operation on the end face of the workpiece. Utility Model Content

[0006] The utility model aims to provide a chamfering machine, which has the advantage of performing rounded corner chamfering operations on the end surface of a workpiece, and solves the problem that the device in the prior art is difficult to perform rounded corner chamfering operations.

[0007] To achieve the above object, the utility model provides the following technical solution: a chamfering machine, comprising an angle grinder body, a mounting frame fixedly mounted on the top of the angle grinder body, and limit frames rotatably mounted on both sides of the mounting frame, and further comprising a first limit roller and a second limit roller;

[0008] The first limiting roller and the second limiting roller are rotatably mounted at two ends of the limiting frame respectively.

[0009] When using a chamfering machine in the technical solution, the top of the angle grinder body is passed through the mounting frame, and the mounting frame is fixedly connected to the top of the angle grinder body by mounting screws. At this time, the tool body is transmission-mounted on the top of the angle grinder body, and the two limit frames are rotatably mounted by positioning bolts. When the end face of the workpiece is chamfered with rounded corners, the first limit roller and the second limit roller are respectively in contact with two adjacent faces of the workpiece. At this time, the tool body is in contact with the end face of the workpiece. By rotating the angle grinder body, the mounting frame is rotated between the two limit frames, thereby realizing the chamfering operation of rounded corners on the end face of the workpiece.

[0010] Preferably, the top of the angle grinder body passes through the mounting frame and is transmission-mounted with a tool body.

[0011] The top of the angle grinder body passes through the mounting frame and the tool body is installed thereon, so that the tool body can be rotated between two limit frames above the mounting frame, thereby realizing the chamfering operation on the end face of the workpiece.

[0012] Preferably, mounting screw holes are respectively provided on both sides of the upper surface of the mounting frame, and positioning bolts are respectively threadedly installed on both sides of the mounting frame.

[0013] Positioning bolts are respectively threadedly installed on both sides of the mounting frame, so that the limiting frame is movably installed through the positioning bolts, so that the limiting frame can rotate on both sides of the mounting frame.

[0014] Preferably, the two limit frames are distributed in a mirror-image manner on both sides of the top of the angle grinder body, and the two limit frames are rotatably connected to the mounting frame through positioning bolts on the mounting frame respectively.

[0015] By distributing the two limit frames in a mirror-image manner on both sides of the top of the angle grinder body, the workpiece can be positioned by the two limit frames during workpiece processing, thereby ensuring that the tool body arranged on the angle grinder body can maintain a corresponding distance from the end face of the workpiece.

[0016] Preferably, the first limiting roller and the second limiting roller form an angle of ninety degrees, and the first limiting roller and the second limiting roller are both designed with stainless steel material.

[0017] By placing the first limiting roller and the second limiting roller at an angle of ninety degrees, it is convenient to clamp the workpiece through the first limiting roller and the second limiting roller. At the same time, the first limiting roller and the second limiting roller are both designed with stainless steel material, thereby enhancing the wear resistance of the first limiting roller and the second limiting roller.

[0018] Preferably, a mounting screw is installed in the inner thread of the mounting screw hole, and the bottom end of the mounting screw passes through the mounting screw hole and is threadedly connected to the top of the angle grinder body.

[0019] The mounting frame and the angle grinder body are fixedly mounted by installing a mounting screw in the mounting screw hole, and passing the bottom end of the mounting screw through the mounting screw hole and being threadedly connected to the top of the angle grinder body.

[0020] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0021] The utility model sets a first limiting roller and a second limiting roller, and rotatably installs the first limiting roller and the second limiting roller at two ends of the limiting frame respectively. When performing specific operations, the top of the angle grinder body passes through the mounting frame, and the mounting frame is fixedly connected to the top of the angle grinder body by mounting screws. At this time, the tool body is transmission-mounted on the top of the angle grinder body, and the two limiting frames are rotatably installed by positioning bolts. When the end face rounding and chamfering operation is performed on the workpiece, the first limiting roller and the second limiting roller are respectively in contact with two adjacent faces of the workpiece. At this time, the tool body is in contact with the end face of the workpiece. By rotating the angle grinder body, the mounting frame is rotated between the two limiting frames, thereby realizing the rounding and chamfering operation on the end face of the workpiece, and achieving the effect of rounding and chamfering the end face of the workpiece.

[0032] Furthermore, the top of the angle grinder body 1 passes through the mounting frame 4 and is transmission-mounted with the tool body 3 .

[0033] The top of the angle grinder body 1 passes through the mounting frame 4 and is driven to mount the tool body 3, so that the tool body 3 can be rotated between the two limit frames 2 above the mounting frame 4, thereby realizing the chamfering operation on the end face of the workpiece.
