Description

Technical Field

[0001] The utility model relates to the field of machining equipment, in particular to a trimming machine for the water inlet and outlet of an arc-shaped eye mask frame. Background Art

[0002] For an arc-shaped eye mask frame formed by injection molding, its surface has an irregular large arc surface and is prone to deformation. Therefore, when trimming its water inlet and outlet, if a three-axis manipulator is used to assist in trimming, the trimming effect is poor. Therefore, the injection molding water inlet and outlet of the arc-shaped eye mask frame are generally removed by manual trimming. However, it is not easy to fix the arc-shaped eye mask frame during manual trimming, resulting in difficulty for workers to accurately trim the area to be cut, and it is easy to form a serrated structure in the area to be cut. In addition, manual trimming not only has extremely low processing efficiency, but also is not conducive to controlling the processing quality of the arc-shaped eye mask frame. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a trimming machine for the water inlet and outlet of an arc-shaped eye mask frame, which can accurately position the arc-shaped eye mask frame when trimming the water inlet and outlet, is convenient for controlling the processing quality and has high processing efficiency.

[0005] Compared with the prior art, the trimming machine for the arc-shaped eye mask frame provided by the utility model accurately positions the arc-shaped eye mask frame by arranging a positioning support plate with a profiling groove on the positioning mechanism, and further fixes the arc-shaped eye mask frame when the trimming knife trims the water inlet and outlet of the arc-shaped eye mask frame by arranging a lifting bracket with an adjustable position in the vertical direction above the positioning mechanism, arranging a trimming knife for trimming the water inlet and outlet on one side of the lifting bracket facing the positioning mechanism, and arranging a profiling pressing plate for fixing the arc-shaped eye mask frame in the profiling groove, so as to avoid the arc-shaped eye mask frame from shifting when trimming the water inlet and outlet, and further control the processing quality. In addition, the positioning mechanism is slidably arranged on the base, so that it is more convenient and fast to load and unload materials when trimming the water inlet and outlet, and there is no need to spend extra time manually fixing the arc-shaped eye mask frame during the trimming process. Therefore, compared with manual trimming, the processing efficiency of the trimming machine for the arc-shaped eye mask frame provided by the utility model is extremely high.

[0011] Specifically, a slide rail is provided on the base, and a connecting slider cooperating with the slide rail is provided on the positioning mechanism so that the positioning mechanism can slide relative to the base. Such a setting makes the positioning mechanism slide more smoothly, improving the reliability of use.

[0021] Next, in combination with specific embodiments and the drawings, the technical solutions in the embodiments of the present application will be clearly and completely described, and the technical solutions of the present utility model will be elaborated. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments.

[0022] Please refer to Figure 2 and Figure 3 , the gate cutting machine 100 for the arc-shaped eye mask frame provided by the present utility model includes a lifting bracket 1, a cutting knife 2, a positioning mechanism 3 and a base 4. The positioning mechanism 3 is slidably arranged on the base 4, the lifting bracket 1 is movably arranged above the positioning mechanism 3 so as to be close to or away from the positioning mechanism 3, and the cutting knife 2 is arranged on one side of the lifting bracket 1 facing the positioning mechanism 3. Specifically, the positioning mechanism 3 includes a positioning support plate 30, a first mounting plate 31 and a second mounting plate 32. The positioning support plate 30 is mounted on the first mounting plate 31, and the second mounting plate 32 is arranged between the first mounting plate 31 and the base 4 and the second mounting plate 32 can slide relative to the base 4. The positioning support plate 30 is provided with a profiling groove 301 for positioning the arc-shaped eye mask frame 200, and the shape of the profiling groove 301 is the same as the shape of the arc-shaped eye mask frame 200. On the side of the lifting bracket 1 facing the positioning mechanism 3, there is also a profiling pressing plate 5 for fixing the arc-shaped eye mask frame 200 in the profiling groove 301.

[0023] Further, please refer to Figure 2, on one side of the lifting bracket 1 facing the positioning mechanism 3, a guiding column 6 is further provided, and on one side of the first mounting plate 31 of the positioning mechanism 3 facing the lifting bracket 1, a guiding hole 311 matching with the guiding column 6 is further provided. In this embodiment, the number of the guiding columns 6 and the guiding holes 311 is four each, and the guiding holes 311 are symmetrically arranged on both sides of the positioning support plate 30, and two guiding holes 311 are provided on each side. Such a setting can guide the lifting bracket 1 to move in a specific direction, so that the cutting knife 2 is more precise during cutting, ensuring the processing quality.

[0024] Further, please refer to Figure 3 , the cutting knife 2 has an annular cutting edge 21 matching with the positioning support plate 30, and the annular cutting edge 21 is convex. Such a setting facilitates cutting in cooperation with the shape of the arc-shaped eye mask frame 200, making the cutting smoother and more efficient. The profiling pressing plate 5 is arranged around the cutting knife 2 and has the same shape as the annular cutting edge 21, also being convex. And on one side of the positioning support plate 30 facing the profiling pressing plate 5 is concave. Such a setting can enable the profiling pressing plate 5 to fully press on the arc-shaped eye mask frame 200, so as to fully fix the arc-shaped eye mask frame 200 in the profiling groove 301. At the same time, in order to prevent the profiling pressing plate 5 from damaging the arc-shaped eye mask frame 200, the profiling pressing plate 5 is made of a flexible material, which further increases the friction between the profiling pressing plate 5 and the arc-shaped eye mask frame 200.

[0025] Furthermore, please refer to Figure 3 , the profiling pressing plate 5 is vertically position-adjustably arranged on the lifting bracket 1. Specifically, a plurality of adjusting bolts 51 are provided on the profiling pressing plate 5 to adjust the relative distance between the profiling pressing plate 5 and the lifting bracket 1. Such a setting facilitates adjusting the position of the profiling pressing plate 5 according to the specifications of the arc-shaped eye mask frame 200, so as to be applicable to the processing of arc-shaped eye mask frames 200 of various specifications.

[0026] Furthermore, the arc-shaped eye mask frame water inlet and outlet cutting machine 100 further includes a first driving mechanism (not shown in the figure) for driving the lifting bracket 1 to move and a second driving mechanism for driving the positioning mechanism 3 to slide. The output end of the first driving mechanism is connected to the lifting bracket 1 to drive the lifting bracket 1 to move. The second driving mechanism includes a control center 70, a hydraulic rod 71, a driving slider 72, and two connecting hoses 73 for accommodating hydraulic medium. Both ends of the hydraulic rod 71 are respectively connected to one end of the two connecting hoses 73, and the other ends of the two connecting hoses 73 are connected to the control center 70. The driving slider 73 is sleeved between both ends of the hydraulic rod 71 and is connected to the second mounting plate 32. The control center 70 can drive the driving slider 72 to reciprocate by controlling the flow of the hydraulic medium. Specifically, when the hydraulic medium flows into the hydraulic rod 71 from one of the connecting hoses 73, the hydraulic medium drives the driving slider 72 to slide in a direction away from the hydraulic medium inlet end, thereby driving the second mounting plate 32 to slide. To facilitate controlling the sliding of the driving slider 72, the second driving mechanism 7 further includes a first start button 74, a second start button 75, and a brake button 76. The first start button 74, the second start button 75, and the brake button 76 are all electrically connected to the control center 70. The first start button 74 is used to drive the driving slider 72 to slide in a first direction (i.e., the direction indicated by arrow A), the second start button 75 is used to drive the driving slider 72 to slide in a second direction (i.e., the direction indicated by arrow B), and the brake button 76 is used to brake the driving slider 72.

[0027] Furthermore, a slide rail 41 is provided on the base 4, and a connecting slider 321 that cooperates with the slide rail 41 is provided on the second mounting plate 32 of the positioning mechanism 3 so that the positioning mechanism 3 can slide relative to the base 4. Such a setting makes the positioning mechanism 3 slide more smoothly and improves the reliability of use. To buffer the sliding of the connecting slider 321 on the slide rail 41, a buffer device 8 is further provided on one side of the base 4. The buffer device 8 includes a kinetic energy absorption end 81 and a body 82. The kinetic energy absorption end 81 extends out of the body 82 and can abut against the side surface of the second mounting plate 32 to absorb part of the kinetic energy and prevent the connecting slider 321 from disengaging from the slide rail 41.

[0028] The following is a description of the working principle of the arc-shaped eye mask frame gate cutting machine 100 provided by the present utility model. First, the positioning mechanism 3 is moved to a position convenient for placing the arc-shaped eye mask frame 200 on the positioning plate 30 by the second driving mechanism. Then, the arc-shaped eye mask frame 200 to be processed is placed in the profiling groove 301 of the positioning plate 30. Then, the arc-shaped eye mask frame 200 is moved to directly below the cutting knife 2 by the second driving mechanism. After that, the first driving mechanism is started to drive the cutting knife 2 to descend, so as to cut off the gate 201 of the arc-shaped eye mask frame 200. After cutting off the gate 201, after the cutting knife 2 is reset, the processed arc-shaped eye mask frame 200 is moved to a position convenient for taking materials by the second driving mechanism, and the processed arc-shaped eye mask frame 200 is taken out from the profiling groove 301. Then, the arc-shaped eye mask frame 200 to be processed is placed in the profiling groove 301, and the foregoing cutting process is continued to be repeated.

[0029] Compared with the prior art, the arc-shaped eye mask frame gate cutting machine 100 provided by the present utility model accurately positions the arc-shaped eye mask frame 200 by providing a positioning plate 30 with a profiling groove 301 on the positioning mechanism 3, and also by providing a lifting bracket 1 that can move closer to or away from the positioning mechanism 3 above the positioning mechanism 3, and providing a cutting knife 2 for cutting the gate 201 and a profiling pressing plate 5 for fixing the arc-shaped eye mask frame 200 in the profiling groove 301 on one side of the lifting bracket 1 facing the positioning mechanism 3, so as to further fix the arc-shaped eye mask frame 200 when the cutting knife 2 cuts off the gate 201 of the arc-shaped eye mask frame 200, and avoid the arc-shaped eye mask frame 200 from shifting when cutting off the gate 201, thereby controlling the processing quality. In addition, the positioning mechanism 3 is slidably arranged on the base 4, so that it is more convenient and fast to place and take materials when cutting off the gate 201, and there is no need to spend extra time manually fixing the arc-shaped eye mask frame 200 during the cutting process. Therefore, compared with manual cutting, the processing efficiency of the arc-shaped eye mask frame cutting machine 100 provided by the present utility model is extremely high.

[0030] The foregoing disclosed content is only the preferred embodiment of the present utility model, and of course it cannot be used to limit the scope of rights of the present utility model. Therefore, equivalent changes made according to the scope of the patent application of the present utility model still fall within the scope covered by the present utility model.
