[0019] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention. On the contrary, the embodiments of the present invention include all variations, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0020] The following describes a pin sawing device according to an embodiment of the present invention in conjunction with the accompanying drawings.

[0021] like Figures 1-4 As shown, the pin shaft sawing device of the embodiment of the present invention includes a device body 1, an electric telescopic rod 2, a slide 3 and a control component 4, wherein the electric telescopic rod 2 is fixed to the device body 1 through a mounting plate, the slide 3 is installed on the output end of the electric telescopic rod 2, and the slide 3 is slidably connected to the device body 1.

[0022] It should be noted that the device body 1 adopts the existing technology, which is the device body 1 in application number 201922416421.3. Its structure and function are the same, both of which are used to transport the pin raw materials, and the slide 3 also has the same principle as the above-mentioned slide 3, both of which are structures for sawing the pin raw materials.

[0023] The control component 4 includes a fixed cylinder 41, a sliding rod 42, a sliding disk 43, a return spring 44, a synchronization disk 45, a trigger switch 46, multiple insertion holes 47, a trigger rod 48 and a unloading mechanism 49, wherein the fixed cylinder 41 is installed on the device body 1, and the sliding rod 42 slides through the fixed cylinder 41.

[0024] It should be noted that when the sliding rod 42 is inserted into the insertion holes 47 at different positions, the pins of different lengths can be controlled to be sawed off, and the position of the sliding rod 42 can be adjusted according to actual needs.

[0025] A sliding plate 43 is mounted on one end of a sliding rod 42 and slides within a fixed cylinder 41. A synchronization plate 45 is mounted on the other end of the sliding rod 42. A return spring 44 is sleeved on the sliding rod 42, with one end of the return spring 44 connected to the fixed cylinder 41 and the other end of the return spring 44 connected to the synchronization plate 45.

[0026] It should be noted that the reset spring 44 always maintains a pulling working state, so that when the synchronizing disc 45 loses its acting force, the reset spring 44 can be used to reset the synchronizing disc 45 .

[0027] The trigger switch 46 is mounted on the sliding plate 43 . A plurality of insertion holes 47 are provided in a linear array on the fixed cylinder 41 . The trigger rods 48 are slidably disposed in the corresponding insertion holes 47 .

[0028] It should be noted that the operation of the device body 1, the electric telescopic rod 2 and the rotating motor 491 is controlled by the trigger switch 46. After the trigger rod 48 contacts the trigger switch 46 once, the trigger switch 46 first controls the output end of the electric telescopic rod 2 to drive the slide knife 3 to move back and forth once to complete the sawing of the pin shaft raw material, and then controls the output end of the rotating motor 491 to rotate to one side to complete the pushing of the sawed pin shaft. When the trigger rod 48 and the trigger switch 46 contact, the device body 1 stops running, and when there is no contact, the device body 1 continues to run.

[0029] The unloading mechanism 49 is provided on the device body 1 , and the unloading mechanism 49 is located above the fixed cylinder 41 .

[0030] Specifically, in the actual operation process, the pins need to be produced continuously, that is, the raw materials of the pins need to be sawed continuously.

[0031] The cam 46 is then released to the touch screen 46, and the cam 46 is ...

[0032] By automatically sawing the pin raw material after it extends to a certain length, the pin can be produced automatically, reducing the steps of manual operation, simplifying the production steps, and improving production efficiency. At the same time, the production length of the pin can be controlled, increasing the adaptability to the pin production needs.

[0033] In one embodiment of the present invention, Figure 4 As shown, the trigger switch 46 and the trigger rod 48 are located on the same straight line, and a rubber plug is installed on the trigger rod 48.

[0034] It should be noted that the rubber plug on the trigger rod 48 is intended to improve the stability of the trigger rod 48 after it is inserted into the insertion hole 47 .

[0035] In one embodiment of the present invention, Figure 2 As shown, the unloading mechanism 49 includes a rotating motor 491 and a pushing plate 492, wherein the rotating motor 491 is mounted on the device body 1. The pushing plate 492 is mounted on the rotating shaft of the rotating motor 491.

[0036] Specifically, during actual operation, if the pin does not fall after the pin raw material is sawed off, the output end of the rotating motor 491 drives the push plate 492 to rotate, so that the push plate 492 pushes the sawed pin to achieve the purpose of assisting the pin to fall.

[0037] In one embodiment of the present invention, Figure 1 As shown, a collection box (not shown) is provided on one side of the device body 1, and the collection box is located on one side of the unloading mechanism 49.

[0038] In summary, the pin sawing device of the embodiment of the utility model automatically saws the pin raw material after the pin raw material extends to a certain length, so that the automated production of the pin can be achieved, the steps of manual operation are reduced, the production steps are simplified, and the production efficiency is improved. At the same time, the production length of the pin can be controlled, and the adaptability to the pin production needs is increased.
