[0038] At the same time, at least two groups of clamping mechanisms 4 are arranged on the turntable 31, and the clamping mechanisms 4 are used to clamp the injection molded parts. Under the action of at least two groups of clamping mechanisms 4, the turntable 31 is set with multiple stations to process multiple groups of injection molded parts;
[0039] refer to Figure 3 and Figure 5 As shown, the clamping mechanism 4 includes a base 41 fixedly mounted on the turntable 31, and a guide rod 43 fixedly mounted on the corner end of the base 41. The guide rod 43 is provided with at least two groups, and a pressure plate 42 is slidably mounted on the guide rod 43. The pressure plate 42 is suitable for approaching or moving away from the base 41. A spring 44 is sleeved on the guide rod 43. The spring 44 is located between the base 41 and the pressure plate 42, so that when the pressure plate 42 is approached to the base 41 by an external force, after the external force disappears, the pressure plate 42 is suitable for resetting through the cooperation of the spring 44;
[0040] A bolt 46 is mounted on the pressing plate 42, and the threaded section of the bolt 46 is located at the bottom of the pressing plate 42. A threaded hole (not shown in the figure) matching the bolt 46 is opened on the base 41. The bolt 46 is suitable for being screwed into the threaded hole and pressing the pressing plate 42. A rotating shaft 45 is mounted on the base 41. The rotating shaft 45 passes through the turntable 31 and the base 41. The top of the rotating shaft 45 matches the injection molded part. An opening matching the injection molded part is opened on the pressing plate 42, so that the end of the injection molded part protrudes from the pressing plate 42.
[0041] When the injection molded part needs to be fixed, the injection molded part is first sleeved on the rotating shaft 45, and then the bolt 46 is rotated. The bolt 46 is suitable for being screwed into the threaded hole and pressing the pressing plate 42, so that the pressing plate 42 approaches the base 41 and presses the injection molded part on the rotating shaft 45. Through the opening on the pressing plate 42, the end of the injection molded part is extended out of the pressing plate 42;
[0042] like Figure 4-Figure 5 As shown, a rotating unit 34 is provided at the bottom of the turntable 31, and the rotating unit 34 is used to drive the rotating shafts 45 on the turntable 31 to rotate. The rotating unit 34 includes an outer gear ring 341 with a bearing installed at the bottom of the turntable 31, and the bottom surface of the outer gear ring 341 is connected to the bearing of the workbench 11, and a driving wheel 342 is meshed at the inner ring of the outer gear ring 341, and a third motor 344 is installed on the hanger 32, and the output end of the third motor 344 is fixedly connected to the driving wheel 342 to drive the driving wheel 342 to rotate;
[0043] A driven wheel 343 is meshed on the outer ring of the outer gear ring 341. The driven wheel 343 is fixed to the bottom end of the rotating shaft 45. Under the action of the third motor 344, the driving wheel 342 is driven to rotate. The outer gear ring 341 is rotated synchronously through the meshing action between the driving wheel 342 and the outer gear ring 341. The meshing action between the outer gear ring 341 and the driven wheel 343 drives the driven wheel 343 to rotate, thereby driving the injection molded parts on the rotating shaft 45 to rotate.
[0044] When the injection molded parts on the clamping mechanism 4 need to be trimmed, first the second motor 33 drives the turntable 31 to rotate, so that the workstations on the turntable 31 are switched, and the clamping mechanism 4 is placed directly below the two sets of cutters 24;
[0045] In which: during the rotation of the turntable 31, the third motor 344 is in a standby state (in the present application, the third motor 344 is a servo motor, which is not limited here), so that the output end of the third motor 344 is in a locked state, and indirectly the driving wheel 342 is in a locked state at this time, and through the meshing action of the driving wheel 342 and the outer gear ring 341, the outer gear ring 341 is also in a locked state. When the turntable 31 rotates, since the rotating shaft 45 is installed with a bearing, and through the cooperation of the driven wheel 343, the driven wheel 343 rolls and moves along the outer ring of the outer gear ring 341, and the rotating shaft 45 rotates to a certain extent during this process;
[0046] After the clamping mechanism 4 on the turntable 31 is in place, the third motor 344 drives the driving wheel 342 to rotate, and under the action of the outer gear ring 341, drives the driven wheel 343 to rotate, and indirectly drives the rotating shaft 45 to rotate, so that the injection molded part rotates under the drive of the rotating shaft 45;
[0047] Then the screw rod 54 is rotated to drive the cutter 24 under the table 53 to approach the injection molded part. After the cutter 24 is in place, the first motor 23 drives the cutter 24 to rotate, and then the driving gear 253 rotates. Under the mutual meshing action of the two sets of racks 251 and the gear 253, the two sets of racks 251 move relatively, and indirectly drive the two sets of slides 22 to approach each other, so that the two sets of cutters 24 are relatively close to each other, so as to synchronously trim and cut both sides of the rotating injection molded part, thereby achieving the purpose of synchronously trimming and cutting both sides of the injection molded part.
[0048] To sum up, through the meshing action of the gear 253 and the two sets of racks 251, when the gear 253 rotates, the two sets of racks 251 are suitable for relative movement, and indirectly drive the cutters 24 under the two sets of slides 22 to move, so as to achieve the purpose of synchronous trimming of both sides of injection molded parts of different widths. At the same time, by setting at least two sets of clamping mechanisms 4 on the turntable 31, the purpose of clamping multiple groups of injection molded parts is achieved, and under the drive of the driving wheel 342, and through the meshing action of the outer gear ring 341 with the driving wheel 342 and the driven wheel 343, the rotating shaft 45 above the driven wheel 343 is rotated, thereby achieving the purpose of all multi-station injection molded parts being able to rotate, and solving the problem of easy offset during the trimming process of injection molded parts.
[0049] The above is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any improvements and modifications within the spirit and principles of the present application and without departing from the principles of the present application shall also be deemed to be within the scope of protection of the present application.
