[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1-Figure 3The utility model provides an embodiment: a semi-automatic pinning machine, including a support frame 6 and an adjustment component, the bottom of the support frame 6 is fixedly connected to a mounting plate 8, the middle of the mounting plate 8 is fixedly connected to a cylinder 2 7, the output end of the cylinder 2 7 is fixedly connected to a moving plate 10, the front side of the moving plate 10 is fixedly connected to a front plate 11, the front side of the front plate 11 is fixedly connected to a plurality of assembly heads 12, the rear side of the moving plate 10 is fixedly connected to a plurality of cylinders 3 9, the output end of the cylinder 3 9 is fixedly connected to a moving block 13, the other end of the moving block 13 is fixedly connected to a push pin 14, and the push pin 14 is slidably connected to the middle of the assembly head 12;

[0030] Specifically, the support frame 6 and the mounting plate 8 provide support for the PIN installation machine. When in use, the position of the support frame 6 is adjusted by adjusting the component to change the position of the assembly head 12. Then, after the assembly head 12 is aligned with the workpiece, the moving block 13 is pushed by driving the cylinder three 9, and then the push pin 14 moves synchronously to push out the PIN pin located inside the assembly head 12, thereby completing the assembly operation of the PIN pin.

[0031] Reference Figure 1-Figure 2 The adjustment component includes a shell 1, which is located above the support frame 6. A motor 3 is fixedly connected to the outside of the shell 1, a threaded rod 2 is fixedly connected to the output end of the motor 3, a slider 4 is threadedly connected to the outer periphery of the threaded rod 2, a cylinder 5 is fixedly connected to the top of the slider 4, and the support frame 6 is fixedly connected to the output end of the cylinder 5; a limit strip 19 is fixedly connected to the inside of the shell 1, and limit slots 20 are provided on the upper and lower sides of the slider 4, and the slider 4 is slidably connected to the outer periphery of the limit strip 19 through the limit slots 20;

[0032] Specifically, when the driving motor 3 is working, the threaded rod 2 can be rotated, and then under the action of the limit groove 20 and the limit strip 19, the slider 4 can be moved inside the shell 1, which can drive the cylinder 15 and the support frame 6 to move, so as to adjust the horizontal position of the support frame 6. After the horizontal position is adjusted, the cylinder 15 can be used to drive the support frame 6 to move up and down, so as to adjust the vertical position of the support frame 6, so as to facilitate the docking of the assembly head 12 and the PIN needle with the workpiece, thereby realizing the semi-automatic assembly of the PIN needle, which can avoid the low assembly efficiency and large errors caused by manual operation, and greatly improve the assembly quality.

[0033] Reference Figure 3 The outer side of the front plate 11 is fixedly connected with a fixed plate 2 18, the outer side of the moving block 13 is fixedly connected with a fixed plate 15, the other end of the fixed plate 15 is rotatably connected with a connecting plate 16, the other end of the connecting plate 16 is rotatably connected with a baffle 17, and the middle part of the baffle 17 is rotatably connected to the outer side of the fixed plate 2 18;

[0034] Specifically, when the moving block 13 moves forward, the fixed plate 15 can push the connecting plate 16 to move. Because the connecting plate 16 and the baffle 17 rotate, the connecting plate 16 and the baffle 17 will be squeezed and rotated during the movement of the connecting plate 16. At this time, the baffle 17 will also rotate along the rotation center point of the fixed plate 2 18, thereby separating the other end of the baffle 17 from the front side of the assembly head 12. Conversely, when the moving block 13 is retracted, the baffle 17 can be rotated to the front side of the assembly head 12 to block and protect the PIN needle and the port of the assembly head 12.

[0035] Reference Figure 3-Figure 4 , a plurality of positioning rods 21 are fixedly connected to the outer side of the movable plate 10, and the positioning rods 21 are slidably connected to the middle part of the mounting plate 8; an arc-shaped guide surface is provided on the inner side of the assembly head 12, and the diameter of the push pin 14 is adapted to the inner diameter of the assembly head 12; there is a gap between the inner side of one end of the baffle 17 away from the connecting plate 16 and the assembly head 12;

[0036] Specifically, when the movable plate 10 and the front plate 11 move forward, they can be restricted by the positioning rod 21, so as to ensure the stability of the front plate 11, and further ensure the assembly quality of the assembly head 12; at the same time, the arc-shaped guide surface on the inner side of the assembly head 12 can guide the end of the push pin 14 when the push pin 14 enters, so as to better push the PIN pin out of the middle of the assembly head 12, and further improve the assembly quality; finally, a gap is set between the baffle 17 and the end of the assembly head 12 to avoid the baffle 17 affecting the PIN pin when the PIN pin is installed.

[0037] Working principle: When in use, the PIN needle to be assembled is placed in the middle of the assembly head 12, and then the motor 3 is driven to drive the threaded rod 2 to rotate, so that the slider 4 drives the support frame 6 to move as a whole, and cooperates with the cylinder 1 5 to adjust the position of the assembly head 12. After adjusting to a suitable position, the cylinder 2 7 is driven to work to push out the moving plate 10, so that the assembly head 12 and the workpiece to be assembled with the PIN needle are docked, and then the moving block 13 is pushed out by driving the cylinder 3 9, and the PIN needle located in the middle of the assembly head 12 is pushed out in cooperation with the push pin 14, so as to complete the assembly of the PIN needle;

[0038] At the same time, after the PIN needle is placed in the middle of the assembly head 12, the cylinder three 9 is retracted to drive the moving block 13 to retract. At this time, the distance between the fixed plate one 15 and the fixed plate two 18 increases. Under the action of the connecting plate 16, the baffle 17 can be rotated along the fixed plate two 18, and then the other end of the baffle 17 can be rotated to the front end of the assembly head 12, so as to block the front end of the assembly head 12 to prevent the PIN needle from falling during the movement. Secondly, when the cylinder three 9 pushes out the moving block 13 and the push pin 14, the baffle 17 rotates in the opposite direction, thereby moving out from the end of the assembly head 12 to avoid affecting the normal assembly of the PIN needle.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
