Description

Technical Field

[0001] The utility model relates to the technical field of milling flash processing, in particular to a robot plastic part milling flash device. Background Art

[0002] During the production of plastic parts, flash is easily formed at the opening and closing positions of the mold. The existence of flash will affect the quality and precision of the product. The purpose of milling flash is mainly to remove excess material or irregular parts on the edge of the product so that the product can meet the expected size and shape requirements.

[0003] In the existing technology, a six-axis robot is often used to move the milling cutter to mill the flash of the workpiece to be processed that is fixed on the fixture table. However, the flash material removed during the processing will directly fall onto the processing table, hindering subsequent processing operations. At this time, manual cleaning is required before subsequent processing can be carried out, resulting in a large amount of manpower required during the processing.

[0004] To this end, we propose a robotic plastic parts milling equipment to solve the above problems. Utility Model Content

[0005] The purpose of the present utility model is to provide a robot plastic parts milling flash device to solve the problems raised in the above background technology.

[0023] In the description of the present invention, it should be understood that terms such as "center," "longitudinal," "lateral," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" indicate positions or locations based on the positions or locations shown in the accompanying drawings. These terms are used solely to facilitate the description of the present invention and to simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0024] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-3 A robot plastic part milling equipment includes a milling flash manipulator 1, a workbench 2, a milling cutter 3 and a frame 4, wherein the milling cutter 3 is installed at the moving head end of the milling flash manipulator 1, the workbench 2 is installed on the frame 4, and the milling flash manipulator 1 is installed on the side of the frame 4. A discharge trough 21 is provided on the upper surface of the workbench 2, and the discharge trough 21 is connected up and down, and a fixture table 5 for fixing the workpiece to be processed is provided in the middle of the discharge trough 21. A material guide cylinder 6 is provided inside the frame 4, and the upper end of the material guide cylinder 6 is connected to the discharge trough 21, and a storage box 7 is provided under the material guide cylinder 6. The removed flash material can fall from the discharge trough 21, and then fall into the storage box 7 through the material guide cylinder 6 for unified collection and processing.

[0027] See also Figure 6Taking into account that the flash material is generally on the periphery of the workpiece to be processed, a pair of support plates 51 are provided on the jig table 5 for sliding. The pair of support plates 51 move from the middle to both sides so as to support the inside of the workpiece to be processed so that the flash faces outward, which is convenient for the milling cutter 3 to cut off. The bottom ends of the pair of support plates 51 are penetrated and threaded with screws 52. One end of the screw 52 is rotatably connected to the side wall of the jig table 5, and the other end is connected to a double-headed motor 53. At the same time, the thread directions of the two screws 52 are opposite, so that when the double-headed motor 53 drives the two screws 52 to rotate, the pair of support plates 51 approach or move away from each other. The grooves on the surface of the jig table 5 can limit the pair of support plates 51, thereby preventing the support plates 51 from deflecting and shifting.

[0028] Furthermore, the support plate 51 adopts a "Z"-shaped structure, and the distance between the upper ends of the pair of support plates 51 is greater than the distance between their lower ends, so that when the support plate 51 supports the workpiece to be processed from the inside, the lower edge of the workpiece to be processed can be as far away from the jig table 5 as possible, thereby reducing the possibility of burrs falling onto the jig table 5.

[0029] See also Figure 4-5 , considering that some hollow workpieces to be processed cannot fall directly on the support plate 51 for support, a number of support plates 8 are rotatably provided between the jig table 5 and the discharge trough 21, so that the hollow workpieces to be processed can be prevented from falling on the support plates 8, and a cylinder 9 is installed in the guide cylinder 6, and the bottom end of the cylinder 9 is installed on the crossbeam in the middle of the frame 4, and a connecting disk 10 is installed at the output end of the cylinder 9, and the connecting disk 10 and the number of support plates 8 are connected by a number of connecting rods 11, and the two ends of the connecting rod 11 are hingedly connected to the connecting disk 10 and the support plate 8, so that when the cylinder 9 is extended and retracted, the support plate 8 can be pulled upward to expand or downward to shrink by the connecting rod 11. When the support plate 8 shrinks, the discharge trough 21 can be emptied, and the fallen burrs can be directly discharged from the discharge trough 21. A support rod 12 is also installed outside the cylinder 9, and the top of the support rod 12 is fixed to the jig table 5 to support the jig table 5.

[0030] Furthermore, in order to improve the stability of the telescopic movement of the output shaft of the cylinder 9, a guide sleeve 13 is also installed on the periphery of the connecting plate 10, the support rod 12 is parallel to the cylinder 9, and the support rod 12 slides through the interior of the guide sleeve 13, thereby utilizing the sliding action of the guide sleeve 13 along the support rod 12 to limit the output shaft of the cylinder 9.

[0031] See also Figure 1-2 Considering that some waste chips are easy to splash when milling burrs, a panel 22 is vertically installed around the upper surface of the workbench 2 to block the scattered chips and reduce the possibility of splashing.

[0032] See also Figure 3In order to facilitate the cleaning of waste in the storage box 7, a straight rail 14 is installed at the bottom of the frame 4. A slider 15 is slidably connected to the straight rail 14, and the slider 15 is fixed to the bottom of the storage box 7, so that the storage box 7 can slide out horizontally relative to the frame 4, making it easy to take out the storage box 7.

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
