Description

Technical Field

[0001] The utility model relates to the technical field of deburring machines, in particular to a multi-directional precision part deburring device. Background Art

[0002] For parts after machining, due to various reasons, burrs generally exist in production. Especially during the machining of micro-holes, burrs often appear around the holes. These burrs not only affect the appearance of the parts, but also affect the positioning of some processes and the assembly of products, thus affecting the performance of the products. After machining micro-holes (especially engineering plastic parts), burrs are often inevitable. In order to ensure that the products do not affect the final use performance, it is necessary to remove the burrs around the small holes.

[0003] In the Chinese utility model patent with the publication number of CN213615716U, a deburring machine for multi-directional deburring is disclosed. By setting the first electric telescopic rod, the extension of the two first electric telescopic rods drives the first moving plate to move downward, and then drives the first grinding wheel to move downward to contact the top of the workpiece. Subsequently, through the extension of the two second electric telescopic rods, the two second moving plates are driven to move relatively, and then drive the two second grinding wheels to contact both sides of the workpiece, so that the two second grinding wheels rotate, enabling multi-directional grinding, increasing the grinding surface of the workpiece, thereby reducing the number of times of turning over by the staff and accelerating the work efficiency.

[0004] Regarding the above related technologies, the inventor believes that there are the following defects: The device drives the second grinding wheels to both sides of the precision part for grinding through two second electric telescopic rods. After the grinding is completed, the two second electric telescopic rods are started again to make the two second grinding wheels leave the precision part, so that the second telescopic rods need to be started before and after the device works to perform deburring work on the surface of the precision part. When grinding the same batch of precision parts, it is very troublesome. Content of the Utility Model

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] By setting a lifting assembly in the present utility model, when the air cylinder is started, the lifting plate moves downward, and at the same time, the mounting plate drives the grinding disc to move downward. During this process, the lifting plate drives two connecting rods to move downward, causing the toothed plate to move downward, so that the transmission gear drives the bidirectional lead screw to rotate, making the two bearing seats drive the sleeve to move towards the surface of the precision part. Under the action of the thin gear, the two thick gears rotate, causing the bevel gear A to drive the two bevel gears B to rotate, and the fixed rod drives the sleeve to rotate through the moving rod, thereby realizing the simultaneous grinding of both sides and the top of the precision part. After the grinding is completed, the air cylinder drives the lifting plate to move upward, causing the two sleeves to move to both sides, realizing that the abutting discs on both sides can automatically abut against the surface of the precision part during grinding, and automatically move away from the precision part after the grinding is completed, facilitating the device to change the position of the precision part and replace the precision part, and improving the working efficiency of the device.

[0018] By setting an adjusting assembly in the present utility model, according to the size of the precision part, the bevel gear D is rotated, causing the bevel gear C to drive the threaded rod to rotate, so that the threaded cylinder drives the abutting disc to change in the horizontal direction, ensuring that when the grinding disc abuts against the top of the precision part, the abutting discs on both sides can just abut against the side of the precision part, enabling the device to adapt to precision parts of different sizes and expanding the application range of the device.

[0030] In the embodiment of the present application, the implementation principle of a multi-directional precision part deburring device is as follows: Start the cylinder 10, so that the lifting plate 6 moves downward, and at the same time the mounting plate 11 drives the grinding disc 13 to move downward.
