Description

Technical Field

[0001] The utility model relates to the technical field of four-jaw chucks, and more specifically, the utility model relates to a four-jaw chuck with a dust and chip prevention mechanism. Background Art

[0002] A four-jaw chuck is a mechanical device used for positioning and clamping workpieces. However, during its actual use, there are still some drawbacks. For example, during the processing of workpieces, a certain amount of dust and chips are often generated. And when the chuck clamps a workpiece, the jaws need to move to the clamping position. At this time, the chute for accommodating the movement of the jaws will be in an open state. Therefore, metal or non-metal dust and chips are likely to enter the inside of the chuck through the chute. Over time, these hard particles will interfere with the drive components inside the chuck, thus affecting the normal use of the four-jaw chuck. Summary of the Utility Model

[0003] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a four-jaw chuck with a dust and chip prevention mechanism to solve the problem that dust and chips in the prior art enter the inside of the jaws through the open chute, affecting its normal use.

[0004] To solve the above technical problems, the utility model provides the following technical solutions: A four-jaw chuck with a dust and chip prevention mechanism includes a fixed seat. An installation disk is rotatably installed on the surface of the fixed seat. A four-jaw chuck body is arranged on the surface of the installation disk. The four-jaw chuck with a dust and chip prevention mechanism further includes

[0005] A shielding cover, the inner wall of the shielding cover is attached to the surface of the four-jaw chuck body;

[0006] A clamping block, the clamping block is fixedly connected to the top surface of the shielding cover, and a fixing hole is formed on the surface of the clamping block;

[0007] A connecting plate, the connecting plate is slidably installed on the surface of the shielding cover;

[0008] An extension cover, the extension cover is fixedly connected to the bottom surface of the connecting plate, and the inner wall of the extension cover is attached to the surface of the four-jaw chuck body;

[0009] A connecting seat one, the connecting seat one is fixedly installed on the surface of the shielding cover. A spring is fixedly connected inside the connecting seat one. The bottom end of the spring is fixedly connected to a connecting column. The surface of the connecting column is attached to the inner wall of the connecting seat one. The bottom end of the connecting column is fixedly connected to a fixed end. The surface of the fixed end is fixedly connected to the surface of the connecting plate.

[0010] Among them, it further includes a threaded end and a clamping rod. The threaded end is threadedly installed inside the first connecting seat. One end of the threaded end is fixedly connected to one end of the clamping rod. The end of the clamping rod away from the threaded end is clamped inside the fixing hole.

[0011] Among them, it further includes an auxiliary component, and the auxiliary component is arranged on the surface of the mounting plate.

[0012] Among them, the auxiliary component includes a connecting frame, a mounting ring, a second connecting seat, an electric push rod, a socket seat, and a through hole. The bottom end of the connecting frame is fixedly connected to the periphery of the four-jaw chuck body. The mounting ring is rotatably installed on the surface of the mounting plate. The surface of the mounting ring is fixedly connected to the top of the connecting frame. The second connecting seat is fixedly connected to the periphery of the mounting ring. The electric push rod is arranged on the surface of the second connecting seat. The socket seat is fixedly connected to the end of the electric push rod away from the second connecting seat. The through hole is opened on the surface of the socket seat. The inside of the socket seat is sleeved with the inside of the clamping block.

[0013] The beneficial effects of the above technical solutions of the present utility model are as follows:

[0014] In the above solution, the electric push rod is set to contract, driving the shielding cover together with the extension cover to fit with the jaws on the surface of the four-jaw chuck body, and covering the chute for accommodating the movement of the jaws. When the jaws move, the spring arranged inside the first connecting seat drives the connecting column to move outward from the first connecting seat by its elastic action, thereby pushing the connecting plate, so that the extension cover can move synchronously with the jaws and continuously fit with the jaws to cover the chute again after the jaws move. Therefore, by covering the chute, it can prevent the dust and chips generated during the processing from entering the chuck through the chute, ensuring that the driving component is not affected by the dust and chips, so that the four-jaw chuck can be used normally;

[0015] Through the arranged mounting ring together with the socket seat, the shielding cover together with the corresponding components can be connected to the chuck and can rotate synchronously with the whole chuck. In addition, by extending the electric push rod, the shielding cover and the extension cover can be driven to separate from the surface of the four-jaw chuck body. Then, by rotating the threaded end, the clamping rod can be separated from the clamping block sleeved inside the socket seat. At this time, the dust-proof mechanism can be disassembled from the surface of the chuck for maintenance, thus achieving the effect of improving the practicality of the device.
