[0034] Next, refer to Figures 1-3 Describe a workpiece cover pressing fixture according to an embodiment of the present utility model.

[0035] As Figures 1-3 shown, the workpiece cover pressing fixture includes a frame 100. A workbench 110 is provided on the frame 100. The workbench 110 is fixed to the surface of the frame 100 by bolts. The frame 100 is provided with a control panel, and the control panel can control the operation of the device.

[0036] It further includes a commutation mechanism, two groups of positioning fixtures 310, a pressing mechanism, and a protective baffle 430.

[0037] The commutation mechanism is arranged inside the frame 100. The commutation mechanism includes a commutation disc 210 and a commutation drive assembly (not shown in the drawings). The commutation drive assembly is arranged inside the frame 100. The output shaft of the commutation drive assembly extends to the workbench 110 and is connected to the commutation disc 210. The commutation drive assembly is used to drive the commutation disc 210 to rotate on the surface of the workbench 110. The commutation drive assembly can drive the commutation disc 210 to rotate 180 degrees each time.

[0038] Two groups of positioning jigs 310 are respectively arranged on both sides of the rotation disk 210. The included angle between the two positioning jigs 310 is 180 degrees. When the rotation disk 210 rotates 180 degrees self - rotatably, the positions of the two positioning jigs 310 are switched with each other, realizing the interchange of two working positions. Every time the rotation disk 210 rotates 180 degrees, the two positioning jigs 310 are successively located directly below the pressing drive assembly 410.

[0039] The pressing mechanism is arranged above the rotation disk 210 and includes a pressing drive assembly 410 and a mounting frame. The mounting frame is arranged on the workbench 110, and the pressing drive assembly 410 is mounted on the mounting frame, and the output end of the pressing drive assembly 410 extends telescopically towards the end face of the rotation disk 210 for pressing the workpiece in the positioning jig 310. After the workpiece cover in the positioning jig 310 below the pressing mechanism is pressed in place, it is switched to the blanking station at the staff's position under the drive of the rotation drive assembly, while the positioning jig 310 originally at the blanking station enters below the pressing mechanism for the next round of pressing operation. The positioning jigs 310 at the two working positions work alternately and simultaneously. While one side is performing the pressing operation, the other side disassembles the finished product and loads a new workpiece, shortening the waiting time for the two pressing operations, improving the production beat of the equipment, and greatly improving the production efficiency.

[0040] One end of the protective baffle 430 is fixed to the mounting frame, and the other end extends towards the rotation disk 210. The positions of the two working positions are separated by the protective baffle 430, playing a protective role to avoid the workpiece at the pressing station being ejected accidentally and injuring the staff, improving the operation safety of the equipment, and also being able to prevent the staff's hand from reaching into the pressing station, reducing potential safety hazards.

[0041] In some embodiments of the present utility model, as Figures 1-3 shown, a positioning pin (not shown in the attached drawings) is provided on the output shaft of the rotation drive assembly, and a corresponding positioning hole 211 is provided in the middle of the rotation disk 210. The rotation disk 210 is installed by inserting the positioning hole 211 into the positioning pin.

[0042] Specifically, the output shaft of the rotation drive assembly and the rotation disk 210 are connected to each other through the mutual matching of the positioning pin and the positioning hole 211 to ensure the correct installation angle of the rotation disk 210.

[0043] In some embodiments of the present utility model, as Figure 1 and Figure 2 shown, the mounting frame includes two support columns 421 and a cross - beam plate 422. The two support columns 421 are respectively located on both sides of the rotation disk 210, and the two ends of the cross - beam plate 422 are respectively connected to the tops of the two support columns 421.

[0044] Specifically, the support column 421 is threadedly fastened to the surface of the workbench 110 and is located on both sides of the transposition disk 210 to prevent interference between the transposition disk 210 and the support column 421 during the rotation of the transposition disk 210. The crossbeam plate 422 is installed above the support column 421, and the crossbeam plate 422 is used to carry the press-in driving assembly 410.

[0045] Further, a mounting hole (not shown in the drawings) is provided in the middle of the crossbeam plate 422. The cylinder block of the press-in driving assembly 410 is disposed on the crossbeam plate 422, and the output shaft passes through the mounting hole and is connected to a press-in plate 411. The press-in driving assembly 410 drives the press-in plate 411 to approach the positioning fixture 310.

[0046] Specifically, the cylinder block of the press-in driving assembly 410 is fixedly installed on the crossbeam plate 422, and its output shaft extends and retracts in the direction of the transposition disk 210 through the mounting hole. A press-in plate 411 is provided below the crossbeam plate 422. The press-in plate 411 is connected to the output shaft of the press-in driving assembly 410. The press-in plate 411 adopts a detachable structure and is used in cooperation with the positioning fixture 310. When different positioning fixtures 310 are replaced, the press-in plate 411 is also correspondingly replaced.

[0047] Further, as Figures 1-3 shown, the press-in plate 411 is provided with a press-in block 412 and a positioning post 413. The positioning fixture 310 is provided with a positioning blind hole 311 at the position corresponding to the positioning post 413. Specifically, during the press-in operation, the positioning post 413 and the positioning blind hole 311 are first inserted to ensure that the press-in block 412 is aligned with the fixture area of the positioning fixture 310. Subsequently, the press-in driving assembly 410 continuously pushes the press-in block 412 downward to squeeze the cover body of the workpiece by the press-in block 412.

[0048] In some embodiments of the present invention, as Figure 1 and Figure 2 shown, the distance between the top end face of the positioning fixture 310 and the bottom end face of the protective baffle 430 is 2 cm to 4 cm. Specifically, the distance between the positioning fixture 310 and the protective baffle 430 can prevent the workpiece of the positioning fixture 310 from colliding with the bottom of the protective baffle 430 during the rotation of the transposition disk 210.

[0049] In some embodiments of the present invention, as Figure 1 and Figure 3 shown, the protective baffle 430 is located between the two positioning fixtures 310. The two sides of the protective baffle 430 are respectively set as a blanking area and a press-in area. Specifically, the protective baffle 430 separates the two areas, ensuring the safety of the blanking area of the staff and reducing potential safety hazards at the same time.

[0050] In some embodiments of the present utility model, the protective baffle 430 is made of a transparent material. In this embodiment, the protective baffle 430 is made of transparent acrylic material, and the staff can observe the workpiece processing situation of the positioning jig 310 in the pressing area through the protective baffle 430.

[0051] Furthermore, the thickness of the protective baffle 430 is 5 mm to 8 mm. Using a protective baffle 430 with a moderate thickness neither affects the staff's observation of the pressing area nor affects the protective performance of the protective baffle 430.

[0052] Furthermore, the protective baffle 430 is detachably connected to the crossbeam plate 422. The damaged protective baffle 430 can be replaced at any time, reducing the maintenance cost.

[0053] In the description of this specification, the descriptions with reference to terms such as "one embodiment", "some embodiments", "schematic embodiments", "examples", "specific examples", or "some examples" etc. mean that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present utility model. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example.
