Detailed Implementation

[0017] like Figures 1 to 5 As shown, a processing device for clamping finished products in one operation includes a support frame 1, a lower module 2, a station switching mechanism 3, and a clamping mechanism 4.

[0018] Furthermore, an upper positioning frame 11 is fixed on the support frame 1; A support block 12 is fixed on the support frame 1; The positioning frame 11 has a first mounting slot and a second mounting slot.

[0019] Furthermore, the lower module 2 is provided with at least two sets, and each set is provided with an ejection mechanism 21; The lower module 2 has a mold groove at the top and a connecting groove at the bottom. The connecting groove has a through hole that communicates with the mold groove. The connecting groove has a positioning hole on its side wall. The mold groove has a texture. The ejection mechanism 21 includes: A threaded sleeve 2101 is provided in the connecting groove, and a screw 2102 is provided on the internal thread of the threaded sleeve 2101. Ejector plate 2103 is rotatably mounted on top of screw 2102. The ejector plate 2103 has the same texture as the mold groove and is connected to the texture in the mold groove. The secondary telescopic tube 2104 has its fixed end fixedly connected to the support plate 31, while its telescopic end is fixed to the top plate 2103. The first bevel gear 2105 is fixed on the threaded sleeve 2101; The transmission rod 2106 is rotatably disposed in the positioning hole. One end of the rod is fixed with a second bevel gear 2107, which meshes with the first bevel gear 2105. The other end is fixed with a driven gear 2108. The first arc-shaped rack 2109 is fixed to the support frame 1 by the first vertical plate and is used to drive the driven gear 2108. The second arc-shaped rack 2110 is fixed to the support frame 1 by the second vertical plate and is installed in the opposite direction to the first arc-shaped rack 2109, and is used to drive the driven gear 2108. The teeth of the first arc-shaped rack 2109 are arranged facing upwards, and the teeth of the second arc-shaped rack 2110 are arranged facing downwards, so that the rotation direction of the driven gear 2108 when it is engaged with the first arc-shaped rack 2109 is opposite to the rotation direction when it is engaged with the second arc-shaped rack 2110.

[0020] Furthermore, the workstation switching mechanism 3 is mounted on the support frame 1 for alternating switching between the lower modules 2, including a support plate 31, with the two lower modules 2 symmetrically distributed on the support plate 31, and the threaded sleeve 2101 rotatably mounted on the support plate 31. The support block 12 on the support frame 1 provides longitudinal support force to the support plate 31 to ensure that the support plate 31 is not deformed by force when clamping; Also includes: The drive motor 32 is fixed to the bottom of the support frame 1 by a stand. The output shaft of the drive motor 32 is fixed with a cylindrical rod 33. The cylindrical rod 33 is rotatably mounted on the support frame 1 and is fixedly connected to the support plate 31. The drive motor 32 is a servo motor. Trigger component 34, used to control the start and stop of drive motor 32, includes: Distance sensor 3401 is fixed in the second mounting slot; The receiver board 3402 is fixed to the top of the lower module 2 and is used to cooperate with the distance sensor 3401. The PLC controller is used to receive feedback from the distance sensor 3401 and control the drive motor 32. The minimum distance between the distance receiver and the receiving board 3402 is set as the starting point for the PLC controller to start the drive motor 32. Whenever the PLC controller receives this feedback value, it controls the drive motor 32 to start. The drive motor 32 is controlled by a PLC controller and a start switch. The start switch is located on the side of the support frame 1 and is used by the operator as a control medium to start the drive motor 32. When the blank is placed in the mold groove, the operator can control the drive motor 32 to work through the start switch.

[0021] Furthermore, the clamping mechanism 4 is provided on the positioning frame 11 and includes a pressure mold 41 for engaging the lower module 2; It also includes an electric push rod 42, which is fixed in the first mounting slot, and the output end of the electric push rod 42 is fixedly connected to the lower module 2.

[0022] A processing device that can produce finished products in one clamping operation, the working principle of which is as follows: 1) Place the blank in the mold groove of the lower module 2, and drive the cylindrical rod 33 to rotate through the drive motor 32, thereby driving the support plate 31 to move the lower module 2 on it, so that the lower module 2 with the newly placed blank moves to the bottom of the pressure mold 41.

[0023] 2) As the support plate 31 moves, the driven gear 2108 at the lower module 2, which is gradually moving away from the mold 41, meshes with the first arc-shaped rack 2109 during the movement. Under the cooperation of the first arc-shaped rack 2109, it rotates. The driven gear 2108 drives the transmission rod 2106 to rotate, and the transmission rod 2106 drives the second bevel gear 2107 to rotate, which in turn drives the first bevel gear 2105 to rotate, causing the threaded sleeve 2101 to be driven, which in turn drives the screw 2102 to move, causing the ejector plate 2103 to move upward under the limitation of the secondary telescopic tube 2104, and ejecting the finished workpiece. Another driven rack at the lower module 2 will mesh with the second arc-shaped rack 2110 during the movement. The driven gear 2108 rotates under the cooperation of the second arc-shaped rack 2110 and the rotation direction is opposite to that of the driven gear 2108 driven by the first arc-shaped rack 2109. At this point, the drive screw 2102 moves downward, thereby driving the top of the ejector plate 2103 to be flush with the bottom wall of the mold cavity.
