Description

Technical Field

[0001] The utility model relates to a sandblasting mechanism, in particular to a swing-type sandblasting mechanism. Background Art

[0002] After the equipment tools (such as milling cutters, drill bits, taps, etc.) are processed, in order to facilitate cutting, the cutting edges are relatively sharp, and they are prone to damage during use, affecting the service life of the tools. Therefore, after the tools are processed, a passivation treatment is required. In general passivation treatment, a sand-carrying nozzle blasts sand at the tool from one angle to passivate the cutting edge. It cannot blast sand at the cutting edge in all directions, resulting in uneven passivation surfaces of the tool and poor passivation effects. Therefore, it has become an urgent problem for those skilled in the art to develop a swing-type sandblasting mechanism. Content of the Utility Model

[0003] The utility model is to solve the above deficiencies and provides a swing-type sandblasting mechanism.

[0004] The above object of the utility model is achieved by the following technical solutions: A swing-type sandblasting mechanism includes a base and a sandblasting device. The sandblasting device is provided with a sandblasting nozzle. It is characterized in that: an arc-shaped guide rail and a sector-shaped direct drive motor stator are provided on the base. A slider capable of reciprocating along the arc-shaped guide rail is installed on the arc-shaped guide rail. The sandblasting device is fixed on the slider. A sector-shaped direct drive motor rotor cooperating with the sector-shaped direct drive motor stator is provided at the bottom of the sandblasting device. The sector-shaped direct drive motor rotor and the sector-shaped direct drive motor stator together form a sector-shaped direct drive motor.

[0005] Further, the sandblasting nozzle is located at the center of the arc of the arc-shaped guide rail.

[0006] Further, a support bearing is provided at the bottom of the sandblasting device.

[0007] The advantage of the utility model compared with the prior art is that: during the sandblasting process, driven by the sector-shaped direct drive motor of the utility model, the nozzle of the sandblasting device can change the sandblasting angle in the circumferential direction of the cutting edge of the tool. Combined with the 360-degree rotation of the tool fixture itself, the cutting edge of the tool can be passivated in all directions comprehensively, achieving a better passivation effect and extending the service life of the tool.

[0010] The following further details the utility model in conjunction with the drawings.

[0011] As Figure 1 , Figure 2 shown, a swing sandblasting mechanism includes a base 1 and a sandblasting device 2. The sandblasting device 2 is provided with a sandblasting nozzle 3. An arc-shaped guide rail 4 and a sector-shaped direct drive motor stator 5 are provided on the base 1. A slider 6 capable of reciprocating along the arc-shaped guide rail 4 is installed on the arc-shaped guide rail 4. The sandblasting device 2 is fixed to the slider 6. A sector-shaped direct drive motor rotor 7 cooperating with the sector-shaped direct drive motor stator 5 is provided at the bottom of the sandblasting device 2. The sector-shaped direct drive motor rotor 7 and the sector-shaped direct drive motor stator 5 together constitute a sector-shaped direct drive motor. The sandblasting nozzle 3 is located at the center of the circle of the arc-shaped guide rail 4. A support bearing 8 is provided at the bottom of the sandblasting device 2 to ensure the smoothness and stability of the sandblasting device 2 when swinging with the sandblasting nozzle 3 as the center. In the present utility model, the sandblasting device 2 is fixed on the slider 6 moving on the arc-shaped guide rail 4, and the sector-shaped direct drive motor provides power, enabling the entire sandblasting device 2 to swing with the sandblasting nozzle 3 as the center, thereby changing the sandblasting direction. At the sandblasting nozzle 3 is the outer circle of the tool. Therefore, the abrasive grains can passivate the tool edge at different angles, making the passivation more uniform and comprehensive, and greatly improving the passivation effect.
