A mechanism for removing burrs from grooves in a hole, the mechanism includes a motor, and a rotary table connected to the motor shaft, and a wire brush is rotatably arranged on the rotary table; when the wire brush rotates relative to the rotary table, at least:

The deployment position protruding beyond the side edge of the turntable,

Gather in the convergent position inside the side edge of the rotary table;

A first limiting body and a second limiting body are respectively arranged on the rotating platform corresponding to the unfolding position and the converging position, and are respectively used to limit the maximum unfolding stroke and the converging stroke of the wire brush.

Further, a stepped screw is provided on the rotating platform, and the wire brush is arranged under the stepped screw to form a rotatable fit.

Further, the step screw is a hexagon socket head shoulder screw.

Further, the first limiting body is a blocking positioning pin, the second limiting body is an elastic limiting body, and the blocking positioning pin and the elastic limiting body are respectively arranged on both sides of the wire brush.

Further, the wire brush, the blocking positioning pin and the elastic limiter form a retractable deburring structure, and the rotary table is provided with two sets of retractable deburring structures, and the two sets of retractable deburring structures are symmetrical to the rotation center of the rotary table set up.

The beneficial effects of the utility model are:

The inner hole groove deburring mechanism of the utility model utilizes the action of centrifugal force to make the wire brush in the expanded position or the retracted position, which can quickly remove the inner groove burrs on the casting cavity parts, and can also quickly and completely withdraw the workpiece, and It can be installed vertically upwards, can also be hung downwards and installed horizontally.

detailed description

The utility model will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

As shown in Figures 1 and 2, a mechanism for removing burrs from grooves in holes includes a motor 1 and a rotary table 2 connected to the rotating shaft of the motor 1, and a wire brush 4 is rotatably provided on the rotary table 2 ; When the wire brush 4 rotates relative to the turntable 2, at least:

protruding from the expansion position outside the side edge of the turntable 2,

Gather in the converging position inside the side edge of the rotary table 2;

A first limiter and a second limiter are respectively provided on the rotary table 2 corresponding to the unfolding position and the converging position, which are respectively used to limit the maximum unfolding stroke and the converging stroke of the wire brush 4 .

A stepped screw 6 is provided on the rotary table 2, and the wire brush 4 is arranged under the stepped screw 7 to form a rotatable fit.

The step screw 6 is a hexagon socket head shoulder screw.

The first limiting body is the blocking positioning pin 5 , the second limiting body is the elastic limiting body 7 , and the blocking positioning pin 5 and the elastic limiting body 7 are respectively arranged on both sides of the wire brush 4 .

The wire brush 4, the blocking positioning pin 5 and the elastic limiter 7 form a retractable deburring structure, and the rotary table 2 is provided with two groups of retractable deburring structures. Centrosymmetrical setup.

Principle of the utility model

In the utility model, as shown in Figure 1, the motor 1 rotates clockwise to drive the rotary table 2 to rotate, and the rotary table 2 expands the wire brush 4 to extend to the burr point of the inner hole groove of the workpiece 3 through the action of centrifugal force. The blocking positioning pin 5 on the side limits the maximum expansion position of the wire brush 4, and the wire brush 4 starts to remove burrs; when the burrs are removed, as shown in Figure 2, the motor 1 rotates counterclockwise through the action of centrifugal force to make the wire brush 4. Fold and limit the maximum converging position of the wire brush 4 through the elastic limit body 7 to ensure that it completely withdraws from the workpiece 3, and the entire inner hole groove deburring process is completed.

In addition, it should be noted that, unless otherwise specified or pointed out, the terms "first", "second" and other descriptions in the specification are only used to distinguish each component, element, step, etc. in the specification, rather than to represent each Logical or sequential relationships among components, elements, and steps, etc.
