[0039] Specifically, see Figure 5 The bottom wall of the vertical slide plate 22 is fixedly connected to a downward pressing mounting plate 26 through a connecting rod 29, the bottom wall of the downward pressing mounting plate 26 is fixedly connected to a contoured recessed block 23, the downward pressing mounting plate 26 is fixedly connected to a plurality of suction cup mounting seats 27, the suction cup mounting seats 27 are fixedly connected to a suction cup cylinder 271, and the piston rod of the suction cup cylinder 271 is fixedly connected to a material taking suction cup 272.

[0040] Specifically, see Figure 5 The downward pressing mounting plate 26 is fixedly connected to two suction cup mounting seats 27, and two suction cup cylinders 271 are symmetrically distributed in the transverse direction. Both suction cup cylinders 271 are inclined downward from outside to inside.

[0041] Specifically, see Figure 5 The downward pressing mounting plate 26 is fixedly connected with a side wall positioning vertical plate 28 , and a positioning inclined surface 281 is provided on the inner side of the side wall positioning vertical plate 28 . The positioning inclined surface 281 is inclined outward from top to bottom, and an avoidance hole 282 is provided on the side wall positioning vertical plate 28 .

[0042] Specifically, see Figure 2 , Figure 3 The base is fixedly connected to a cylinder mounting seat 41, and the cylinder mounting seat 41 is provided with an inclined top plate 42. The edge of the inclined top plate 42 on the lower side is hinged to the cylinder mounting seat 41, and the edge of the inclined top plate 42 on the upper side is connected to the cylinder mounting seat 41 by screws.

[0043] Specifically, Figure 3 A guide track 311 is provided on the top wall of the stroke cylinder 31 , and the drilling rig mounting seat 32 is slidably connected to the guide track 311 .

[0044] Specifically, see Figure 1 The base is fixed with a transverse slide rail 51 and a rodless cylinder 52, the rodless cylinder 52 is arranged in the transverse direction, and the transverse slide rail 51 is slidably connected with a transverse slide 53. The positioning fixture 1 is fixed to the top wall of the transverse slide 53. The base is provided with a discharge port 54, which is located below the pressing mounting plate 26.

[0045] Specifically, a loading robot arm 6 is fixedly connected to the base, the loading robot arm 6 is provided with a loading slide 61, and the loading slide 61 is fixedly connected to a loading suction cup (not shown in the figure).

[0046] The working principle of the bottom nozzle drilling and milling device of the hemispherical cup plastic part of the utility model is as follows:

[0047] See Figure 1 , the transverse slide 53 first moves to position B, and the loading fixture (position A) places the hemispherical cup body plastic part 7 to be drilled and milled ( Figure 1 The base is fixedly connected with a loading robot arm 6, which is provided with a loading slide 61, and the loading slide 61 is fixedly connected with a loading suction cup (not shown in the figure). When the loading suction cup places the hemispherical cup body plastic part 7 ( Figure 1 After being adsorbed by the hemispherical cup body plastic part 7 (not shown), the loading slide 61 drives the hemispherical cup body plastic part 7 to move upward, and then moves horizontally to above the horizontal movement slide 53 at position B.

[0048] Combination Figure 6 The positioning fixture 1 is fixed to the top wall of the transverse slide 53. The positioning fixture 1 is provided with a profiling convex portion 11. The profiling convex portion 11 is in a hemispherical shape and is used to place the hemispherical cup body plastic part 7. After the loading suction cup (not shown in the figure) places the hemispherical cup body plastic part 7 on the profiling convex portion 11, the transverse slide 53 moves from position B to Figure 1 Position shown.

[0049] Then, the downward pressure cylinder 25 drives the vertical slide plate 22 to move downward, driving the profiling concave block 23 to move downward. The bottom wall of the profiling concave block 23 is provided with a profiling concave surface 231, and the shape of the profiling concave surface 231 corresponds to the shape of the top wall of the hemispherical cup body plastic part 7. After the vertical slide plate 22 moves down to the right position, the profiling concave surface 231 presses the top wall of the hemispherical cup body plastic part 7, and at the same time, the positioning inclined surface 281 moves down to abut against the plane side wall 72 of the hemispherical cup body plastic part 7, thereby positioning the hemispherical cup body plastic part 7 together with the profiling convex part 11.

[0050] Then, see Figure 3The stroke cylinder 31 drives the drilling machine mounting seat 32 to move forward, so that the front end of the drilling and milling cutter rod 331 passes through the avoidance hole 282 set in the side wall positioning vertical plate 28, and drills and mills the water inlet position 71 of the hemispherical cup body plastic part 7 (see Figure 7 ).

[0051] After the drilling and milling of the water inlet position 71 is completed, the stroke cylinder 31 drives the drilling machine mounting seat 32 to reset, so that the drilling and milling cutter rod 331 is withdrawn from the avoidance hole 282, and then, Figure 5 The two suction cup cylinders 271 drive the material taking suction cups 272 to extend outward, and the two material taking suction cups 272 both contact the outer wall of the hemispherical cup body plastic part 7, thereby jointly adsorbing the hemispherical cup body plastic part 7.

[0052] Then, the pressing cylinder 25 drives the pressing mounting plate 26 to move upward and reset, thereby driving the hemispherical cup body plastic part 7 to move upward and thus separate from the contoured protrusion 11. Then, the rodless cylinder 52 drives the lateral sliding table 53 from Figure 1 The position shown is moved to position B, so as not to block the hemispherical cup body plastic part 7. Then, the material taking suction cup 272 stops sucking air, so that the hemispherical cup body plastic part 7 falls into the discharge port 54 under the action of gravity, and is then output by the conveyor belt (not shown in the figure).

[0053] The drilling and milling device for the bottom sprue of a hemispherical cup-shaped plastic part of the utility model is provided with automated mechanisms such as a transverse slide 53, a loading robot arm 6, and a material taking suction cup 272. It can automatically load materials in cooperation with a drilling rig 33, and then drill and mill the sprue of the product, thereby avoiding a series of manual processing processes on the sprue, thereby reducing the amount of labor, and at the same time improving the consistency of the processing of the sprue position 71, and improving the surface quality of the processing of the sprue position 71.

Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
