Description

Technical Field

[0001] This utility model relates to the field of wood frame production technology, specifically to a wood frame rotating clamping device. Background Technology

[0002] Some wooden frames consist of two side panels and multiple cross panels between them. Nails are needed at the joints between the side panels and the cross panels to ensure a reliable connection. While the nailing process is automated by a robotic arm, the nailing equipment only has one frame loading station. After loading, the robotic arm must nail each joint individually. Once all joints are nailed, the frame must be manually removed from the loading station, and another frame to be nailed must be placed there. Because the nailing equipment only has one loading station, the nailing and loading processes must alternate, resulting in waiting time and low efficiency in the nailing process.

A positioning pin 15 is slidably inserted through the guide sleeve 14. A pin cylinder 16 is fixedly connected to the pin cylinder seat 13. The piston rod of the pin cylinder 16 is coaxially fixedly connected to the positioning pin 15.

[0030] Specifically, an input gear 17 is fixedly fitted onto the lower end of the rotating shaft 12. A transverse slide rail 18 is fixedly connected to the top wall of the base cavity, and a reciprocating rack 19 is slidably connected to the transverse slide rail 18. A transverse cylinder 191 is fixedly connected to the top wall of the base cavity, and the piston rod of the transverse cylinder 191 is fixedly connected to the reciprocating rack 19.

[0031] Specifically, a lower mounting frame 4 is fixed to the top wall of the inner cavity of the base. The lower mounting frame 4 is U-shaped. The left and right frame bars of the lower mounting frame 4 are fixed with forward-extending air pressure buffers 41. The lower end of the rotating shaft 12 is fixed with a limit bar 121.

[0033] Specifically, the upper inner edge of the movable clamp 35 is provided with a strip-shaped notch, and the side wall of the strip-shaped notch is fixed with a strip by screws.

[0034] Specifically, a strip is fixed to the upper rear edge of the front positioning plate 37 by screws.

[0035] Specifically, the top wall of the turntable 21 is fixedly connected to the upper mounting frame 24, and the middle partition 22 is installed inside the upper mounting frame 24. The middle partition 22 is a PC board.

[0036] Specifically, a slip ring 42 is fixedly connected to the lower side of the limiting strip 121. The lower end of the slip ring 42 is fixedly connected to the lower mounting frame 4. The slip ring 42 is coaxially arranged with the rotating shaft 12, which is a hollow shaft.

[0037] The working principle of this utility model is as follows:

[0038] See Fig. 1 The wooden frame 5 consists of two side panels and multiple horizontal panels positioned between them. First, the multiple panels are initially glued together to form the wooden frame 5. Then, the wooden frame 5 is placed in the wooden frame clamp 3 for clamping. Before clamping, the bottom wall of the wooden frame 5 is placed against the top edges of the left vertical panel 31 and the right vertical panel 32, the front wall of the wooden frame 5 is placed against the strip on the front positioning plate 37, and the right edge of the bottom wall of the wooden frame 5 is placed against the strip on the fixing clamp 34. Then, the clamping cylinder 36 moves the movable clamping plate 35 inward, thereby clamping the wooden frame 5.

[0039] The nailing mechanism (not shown in the figure) of this utility model is used to nail the two side plates at the positions corresponding to the edges of the horizontal plate, thereby fixing the side plates to the horizontal plate.

[0040] The two wooden frame clamps 3 are symmetrical about the central axis of the turntable 21, and there is a partition 22 between the two wooden frame clamps 3. This allows the worker to pick up or load materials from the rear wooden frame clamp 3 while the front wooden frame 5 is being nailed. After the nailing of the front wooden frame 5 is completed, the turntable 21 rotates 180° to swap the positions of the wooden frame 5 that has been loaded and the wooden frame 5 that has been nailed. This facilitates worker operation and achieves seamless connection between loading and unloading, thereby improving work efficiency.

[0041] The transverse cylinder 191 serves as the power source. Its piston rod is fixedly connected to the reciprocating rack 19, thereby driving the input gear 17 (turntable 21) to alternately rotate 180° forward and 180° backward. After the turntable 21 rotates 180° forward or backward, the limit bar 121 swings to touch the pneumatic buffer 41 on either side, providing a cushioning effect. Subsequently, the pin cylinder 16 drives the positioning pin 15 to move upward relative to the guide sleeve 14 and partially insert into a positioning socket 23, thereby locking the turntable 21.

Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
