[0021] The following further describes the present application in detail with reference to the Figures 1-4 accompanying drawings.

[0022] Embodiment 1

[0023] The embodiment of the present application discloses a positioning mechanism of a button sewing machine. Refer to Figures 1-2 , a positioning mechanism of a button sewing machine, includes a cover plate 1. A cavity is formed in the middle of the cover plate 1. A plurality of guide slots are formed on both sides of the cavity. A driving assembly 2 is installed on the cover plate 1. The driving assembly 2 includes a turntable 201 rotatably arranged in the cavity. Two arc-shaped grooves are formed on the turntable 201. The two arc-shaped grooves are distributed along the circumferential direction. Guide posts 202 are slidably installed in the two arc-shaped grooves respectively. A clamping arm for clamping a button is installed on the guide post 202. By rotating the turntable 201 to drive the guide post 202 to pull the two clamping arms to move towards each other or away from each other, the clamping and releasing of the button are completed.

[0024] Refer to Figure 1 , the input shaft of the turntable 201 passes through the cover plate 1 and is connected with a driving source 203. The driving source 203 can be selected as a driving motor or a rotary cylinder according to needs. By driving the turntable 201 to rotate through the driving source 203, the guide post 202 is driven to move, and the clamping arm is pulled to move, so as to clamp and release the button.

[0025] Refer to Figure 2, when the clamping arms are misaligned clamping arms, the long clamping arm 3 includes two L-shaped rods 301 respectively sleeved on the guide posts 202. The two L-shaped rods 301 are respectively slidably installed in the corresponding guide notches. The two guide notches on the cover plate 1 are distributed parallel to the X-axis and penetrate through the two side walls of the cover plate 1. The L-shaped rods 301 are limited by the guide notches to ensure the smoothness of movement and prevent the L-shaped rods 301 from shifting during the movement of the guide posts 202. Clamping buckle grooves 302 are formed at the ends of the L-shaped rods 301. A cloth pressing rod 4 is installed on the cover plate 1, and button-holing holes are formed inside the two clamping buckle grooves 302 on the cloth pressing rod 4. By driving the turntable 201 to rotate through the driving source 203, the guide posts 202 are driven to move along and pull the L-shaped rods 301 to move, so that the two L-shaped rods 301 approach or move away from each other to clamp the mushroom buttons from the fixture.

[0026] Embodiment 2

[0027] This application embodiment discloses a positioning mechanism of a button-holing machine. Refer to Figures 3-4 , a positioning mechanism of a button-holing machine, includes a cover plate 1. A cavity is formed in the middle of the cover plate 1, and a plurality of guide notches are formed on both sides of the cavity. A driving assembly 2 is installed on the cover plate 1. The driving assembly 2 includes a turntable 201 rotatably arranged in the cavity. Two arc-shaped grooves are formed on the turntable 201. The two arc-shaped grooves are distributed along the circumferential direction. Guide posts 202 are slidably installed in the two arc-shaped grooves respectively. Clamping arms for clamping buttons are installed on the guide posts 202. By rotating the turntable 201 to drive the guide posts 202 to pull the two clamping arms to move towards each other or away from each other, the clamping and releasing of the buttons are completed.

[0028] Refer to Figure 4 , the input shaft of the turntable 201 passes through the cover plate 1 and is connected with a driving source 203. The driving source 203 can be selected as a driving motor or a rotary cylinder according to needs. By driving the turntable 201 to rotate through the driving source 203, the guide posts 202 are driven to move and pull the clamping arms to move for the clamping and releasing of the buttons.

[0029] Refer to Figure 3 , when the clamping arms are symmetrically distributed clamping arms, the two guide notches on the cover plate 1 are collinearly distributed along the X-axis. The short clamping arm 6 includes two L-shaped plates 601 respectively sleeved on the guide posts 202. The two L-shaped plates 601 are respectively slidably installed in the corresponding guide notches. Clamping buckle grooves 602 are formed at the ends of the two L-shaped plates 601. The L-shaped plates 601 are limited by the guide notches to ensure the smoothness of movement and prevent the L-shaped plates 601 from shifting during the movement of the guide posts 202. Clamping buckle grooves 602 are installed at the ends of the L-shaped plates 601.

[0030] Refer to Figure 4, a moving groove is formed on one side of the cover plate 1 close to the button nailing notch. Two L-shaped plates 601 are slidably installed in the moving groove. The moving groove guides the translation of the L-shaped plates 601 to ensure the smoothness of the movement. A second pressing rod 5 is installed on the cover plate 1. A button nailing notch is formed on the second pressing rod 5, and the button nailing notch is located inside the two L-shaped plates 601. The driving source 203 drives the turntable 201 to rotate, and then drives the guide post 202 to move along the pulling L-shaped rod 301, so that the two L-shaped rods 301 approach or move away from each other to clamp the mushroom button from the fixture;

[0031] Compared with the first solution, the avoidance part of the second solution can be not affected by 1, realizing the shortening of the overall length of the clamping arm and making the overall structure more compact.
