[0001] The present application relates to the technical field of screw feeding equipment, and in particular to a rotary hook screw machine. Background Art

[0002] The rotary hook is an important component of a sewing machine. Among sewing equipment, the most common sewing machine is the one that uses lockstitch stitching.

[0003] Since a plurality of screws need to be installed on the outer wall of the rotary hook, usually, the screws on the rotary hook need to be installed manually by a worker, which is a time-consuming and labor-intensive process and there is still room for improvement. Utility Model Content

[0004] In order to facilitate the installation of screws on the outer wall of a rotary hook, the present application provides a rotary hook screw machine.

[0005] The present application provides a rotary hook screw machine, which adopts the following technical solution:

[0006] A rotary hook screw machine comprises a workbench placed on a table, one side of the workbench is fixedly connected to a support frame arranged perpendicular to the workbench;

[0007] A clamping assembly, mounted on the workbench, for clamping the rotary hook;

[0008] A rotating assembly, mounted on the workbench and connected to the clamping assembly, for driving the clamping assembly to rotate;

[0009] A storage table is fixedly connected to the workbench, and the storage table is provided with a plurality of mounting slots for placing screws;

[0010] A feeding assembly is installed on the support frame and is used to take out the screws in the installation slot and install them in the rotary hook on the clamping assembly;

[0011] The first sliding assembly is installed on the support frame, and the loading assembly is connected to the first sliding assembly and is used to drive the loading assembly to move.

[0012] By adopting the above technical solution, the staff places the screws in the installation slot on the storage table, and the first sliding component drives the loading component to move and align the screws, thereby moving the screws and installing them in the rotary shuttle on the clamping component. The rotating component can drive the rotary shuttle to rotate circumferentially, thereby facilitating the installation of screws in multiple directions, making it possible to automate the screw installation work, reduce the manual operation steps of the staff, and save time and effort.

[0013] Optionally, the clamping assembly includes:

[0014] A three-jaw chuck fixedly connected to the rotating assembly;

[0015] A mounting block is fixedly connected to a side of the three-jaw chuck away from the rotating assembly, the mounting block is provided with a placement groove for the rotary hook to be engaged, and the mounting block is provided with a sliding groove that passes through the outer circumferential side wall and is connected to the placement groove;

[0016] A fixing screw is slidably connected in the slide groove, and one end of the fixing screw extends into the rotary hook and is used to fix the rotary hook;

[0017] The claws of the three-jaw chuck extend into the slide slot, and one end of the claws of the three-jaw chuck extending into the slide slot is fixedly connected to the fixing screw, so as to drive the fixing screw into the rotary hook.

[0018] By adopting the above technical solution, the structure of the clamping assembly is specifically disclosed. After the staff clamps the rotary hook into the placement groove on the mounting block, the clamping claws on the three-jaw chuck push the fixing screw into the rotary hook, thereby further clamping the rotary hook and improving the clamping stability of the rotary hook.

[0019] Optionally, a side of the mounting block away from the three-jaw chuck is fixedly connected to a limiting column located in the placement groove, and a limiting surface that abuts against the fixing screw is formed on the limiting column.

[0020] By adopting the above technical solution, a limiting surface is provided on the limiting column, so that the limiting column can be clamped in the rotary hook to preliminarily fix the rotary hook. The three limiting surfaces cooperate with each other to form a triangular surface, so that the fixing screw extends into the rotary hook and abuts against the limiting surface, which makes it easier for the three-jaw chuck to control the fixing screw to fix the rotary hook, thereby improving the clamping efficiency of the clamping assembly on the rotary hook.

[0021] Optionally, the mounting block is provided with an abutting surface for abutting against the rotary hook.

[0022] By adopting the above technical solution, the setting of the abutment surface allows part of the outer wall of the rotary hook to abut against the abutment surface, reducing the possibility of the rotary hook rotating in the circumferential direction before the fixing screw clamps the rotary hook, making it easier for the fixing screw to extend into the rotary hook, thereby improving the clamping efficiency.

[0023] Optionally, the rotating assembly includes:

[0024] A fixing frame connected to the workbench;

[0025] A rotary cylinder is fixedly connected to the fixing frame, and a piston rod of the rotary cylinder passes through the fixing frame and is fixedly connected to a side of the three-jaw chuck away from the mounting block, for driving the three-jaw chuck to rotate circumferentially.

[0026] By adopting the above technical solution, the specific structure of the rotating assembly is disclosed. The rotating cylinder can drive the three-jaw chuck to rotate circumferentially, thereby driving the rotary shuttle to rotate circumferentially, making it convenient for the loading assembly to rotate and install screws in multiple positions on the outer wall of the rotary shuttle.

[0027] Optionally, the first sliding assembly includes:

[0028] An inline linear module is fixedly connected to the workbench, and the inline linear module includes a first movable platform for mounting the fixing frame, and is used to drive the fixing frame to move along the length direction of the inline linear module;

[0029] The first drive motor is fixedly connected to the side of the workbench away from the support frame. The linear module also includes a screw for driving the mobile platform to move. The output shaft of the first drive motor is connected to the screw through a transmission belt to drive the linear module to open and close.

[0030] By adopting the above technical solution, the specific structure of the first sliding assembly is disclosed. The first drive motor drives the screw on the linear module to rotate through a belt, so that the first movable platform drives the shuttle on the clamping assembly to move close to or away from the staff, making it easier for the staff to remove or install the shuttle.

[0031] Optionally, the first sliding assembly further includes:

[0032] The limiting frame is fixedly connected to one side of the workbench close to the supporting frame. The straight line module is located in the limiting frame. The limiting blocks are fixedly connected to the two opposite inner side walls of the limiting frame.

[0033] By adopting the above technical solution and setting up the limit frame, when the first mobile platform moves to the end of the slide rail on the straight line mold, the limit block on the limit frame can abut against the first mobile platform, thereby reducing the possibility of the first mobile platform moving excessively and detaching from the slide groove, and improving the movement stability of the first mobile platform.

[0034] Optionally, the second sliding assembly includes:

[0035] A cross sliding module is fixedly connected to the support frame and is located above the storage table. The cross sliding module includes a second movable platform for installing the loading assembly.

[0036] By adopting the above technical solution, the specific structure of the second sliding component is disclosed. The cross sliding module can drive the loading component to move up and down, thereby moving closer to or away from the screw; it can also drive the loading component to move left and right, thereby realizing the horizontal movement of the loading component to the top of the clamping component, thereby improving the movement efficiency of the loading component.

[0037] Optionally, the feeding assembly includes:

[0038] A mobile frame is slidably connected to the second mobile platform,

[0039] a second drive motor fixedly connected to the second mobile platform, wherein a rotating rod is coaxially provided on an output shaft of the second drive motor;

[0040] The suction head is fixedly connected to the movable frame and is located above the mounting slot. The suction head is fixedly connected to an air pipe for adsorbing the screw in the mounting slot. One end of the rotating rod extends into the suction head and abuts against the screw, so as to drive the screw in the suction head to rotate.

[0041] By adopting the above technical solution, the specific structure of the loading assembly is disclosed. Under the action of the air pressure in the trachea, the suction head absorbs the screws on the storage table into the suction head. When the loading assembly is located above the rotary hook, after the trachea is ventilated, the second drive motor can drive the rotating rod to rotate circumferentially, thereby threading the screw in the suction head to the rotary hook, thereby improving the efficiency of automatic tightening of the screw.

[0042] Optionally, a connecting platform is fixedly connected to one side of the workbench close to the supporting frame, and a slot for the storage platform to be connected is provided on the connecting platform.

[0043] By adopting the above technical solution, the setting of the connecting platform and the card slot can further raise the height of the storage table, thereby reducing the distance between the storage table and the loading assembly, and at the same time can make the storage table more stably installed on the connecting platform, thereby improving the installation stability of the storage table.

[0044] In summary, this application includes at least one of the following beneficial technical effects:

[0045] 1. The first sliding assembly drives the loading assembly to move the screws in the installation slot into the rotary hook. The rotating assembly can drive the rotary hook to rotate circumferentially, thereby facilitating the installation of screws in multiple directions. This enables automated screw installation, reduces manual operation steps, and saves time and effort.

[0046] 2. The abutment surface allows part of the outer wall of the rotary hook to abut against the abutment surface, reducing the possibility of the rotary hook rotating in the circumferential direction before the fixing screw clamps the rotary hook, making it easier for the fixing screw to extend into the rotary hook, thereby improving the clamping efficiency;

[0047] 3. The setting of the connecting platform and the card slot can further raise the height of the storage platform, thereby reducing the distance between the storage platform and the loading assembly. At the same time, it can make the storage platform more stably installed on the connecting platform, thereby improving the installation stability of the storage platform.
