Description

Technical Field

[0001] This utility model relates to the field of deburring equipment technology, and more specifically to an automatic deburring machine. Background Technology

[0002] During the powder metallurgy pressing process, a large number of burrs are generated around the blank. If the burrs can be removed at the blank stage, the surface quality of the sintered product will be significantly improved, which can greatly reduce the workload of subsequent passivation and polishing, and is conducive to improving product quality.

[0003] There are also some existing deburring devices, such as the utility model application with application number 202121252720.9, which discloses a deburring device for mold parts. The first cylinder pushes the connecting rod to move downward, which in turn moves the connecting plate downward, thereby moving the deburring assembly and the blowing assembly downward. The output end of the movable motor rotates, which drives the first drive rod to rotate, thereby driving the deburring brush to rotate. The deburring brush removes burrs from the mold parts, and the fan blade blows away the burr debris generated during the deburring process.

[0004] However, the existing deburring equipment is not suitable for deburring batches of products, and its precision control for deburring is also insufficient. Summary of the Invention

Detailed Implementation

[0018] The present invention will be further illustrated by specific embodiments below. However, these examples are only for illustrative purposes and are not intended to limit the scope of the present invention.

[0019] Example

[0020] like Figure 1 and 2 As shown, an automatic deburring machine includes a frame base, and an X-axis linear module, a Y-axis linear module, and a Z-axis linear module mounted on the frame base. The Z-axis linear module is equipped with a brush mechanism for driving the brush mechanism to move in the Z-axis direction. The brush mechanism is an electrically driven rotating brush mechanism, including a brush motor 11 and a brush head 13. In this embodiment, a disc-shaped brush head 13 is used, which rotates under the drive of the brush motor 11. The Y-axis linear module is equipped with a laser distance sensor 8, which automatically measures the distance from the blank 2 to the brush mechanism. Based on the distance measured by the laser distance sensor 8, the Z-axis linear module automatically adjusts the height of the brush mechanism to achieve the best deburring effect. The frame base is equipped with a graphite plate 1, on which several blanks 2 to be deburred are mounted. The deburring machine is also equipped with a purge air pipe 12, which is set together with the brush mechanism on the Z-axis linear module. The purge air pipe 12 is connected to compressed air and is used to simultaneously purge the blank 2 to be deburred. During the deburring process of the brush mechanism, a lot of debris is generated. By simultaneously purging with the purge air pipe 12, the debris can be removed in time, improving the deburring efficiency and avoiding the impact of debris residue on the blank 2 on the deburring effect.

[0021] The Y-axis linear module is equipped with the Z-axis linear module, which drives the Z-axis linear module to move in the Y-axis direction; the X-axis linear module is equipped with the Y-axis linear module, which drives the Y-axis linear module to move in the X-axis direction. Through the combined action of the XYZ three-axis linear modules, the brush mechanism can move freely above the graphite plate 1 to perform deburring operation on the blank 2 on the graphite plate 1.

[0022] The frame base includes several mutually perpendicularly arranged X-axis base frames 4 and Y-axis base frames 3; the X-axis linear module is disposed on the X-axis base frame, and the graphite plate 1 is disposed on the Y-axis base frame 3.

[0023] The X-axis linear module includes two X-axis guide rails 5, an X-axis stepper motor 16, and a drive shaft 15; the X-axis stepper motor 16 is used to drive the Y-axis linear module to move linearly on the X-axis guide rails 5; the X-axis guide rails 5 are mounted on the X-axis base frame 4 of the frame base.

[0024] The Y-axis linear module includes a Y-axis guide rail 6 and a Y-axis stepper motor 14. The Y-axis stepper motor 14 is used to drive the Z-axis linear module to move linearly on the Y-axis guide rail 6. The Y-axis guide rail 6 is perpendicularly arranged on the two X-axis guide rails 5 of the X-axis linear module.

[0025] The Z-axis linear module includes a Z-axis guide rail 17, a brush motor mounting plate 10, and a Z-axis stepper motor 9. The brush mechanism is slidably connected to the Z-axis guide rail 17 via the brush motor mounting plate 10, and the Z-axis stepper motor 9 is used to drive the brush mechanism to perform linear motion on the Z-axis guide rail 17.

[0026] The laser distance sensor 8 is fixed to the Y-axis guide rail 6 of the Y-axis linear module via the sensor mounting plate 7.

[0027] The working principle of the above-mentioned automatic deburring machine is as follows:

[0028] First, the staff places the graphite plate 1 and the blank 2 with deburring material on the Y-base 3. Then, they click the start button on the touch screen. The X-axis linear module drives the laser displacement sensor 8 to move above the blank 2 to measure the distance between the top of the blank 2 and the brush, and transmits the data to the system. The system automatically calculates the downward pressure of the brush and executes it by the Z-axis linear module. The system sends a signal to the X-axis and Y-axis linear modules to drive the brush head 13 to brush the entire blank 2 on the graphite plate 1 to remove burrs. While the brush mechanism is removing burrs, the blowing pipe simultaneously blows away the generated burrs, resulting in high deburring efficiency and good effect.

[0029] The above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model. The patent protection scope of the present utility model should be defined by the claims.
