Detailed ways

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in FIG. 1-3, a pin feeding device of the present invention includes a driving device 210, a clamping device 220 and a pin feed holder 230. One end of the clamping device 220 is connected to the driving device 210, and the driving device is connected. 210 may be a cylinder or cylinder and the clamping device 220 is slidably coupled to the pin feed socket 230.

The clamping device 220 includes a pin feed plate 221, one end of which is connected to the output end 211 of the driving device 210, and the other end has one or more clamping ends, preferably, the pin feeding plate 221 There are two clamping ends at one end. The clamping device 220 further includes one or more clamping arms 222. Preferably, the pin feeding plate 221 includes two clamping arms 222. The middle of the clamping arms 222 is rotatably connected to the pin feeding plate 221 by a torsion spring and a pin. One end of the clamp arm 222 and the two clamping end portions of the pin feed plate 221 form a clamping portion for clamping the pin shaft, each of the clamping portions can respectively clamp the pin shaft, and the other end of the clamping arm 222 protrudes from the pin shaft. The plate 221 is pressed by the other end of the clamp arm 222 toward the center line of the pin feed plate 221, and the clamp arm 222 is rotated by the middle pin, one end is away from the pin feed plate 221, and the clamping portion is opened, when the pressing force is lost. After The clamping portion is closed by the action of the torsion spring.

The pin feed holder 230 includes a base 231 and a cover plate 232. The cover plate 232 is disposed at one end of the base 231 to form a rectangular parallelepiped through hole through which the clamping device 220 can pass. The remaining portion of the base 231 is a flat plate for the clamping device 220 to be Slide above.

As shown in FIGS. 3 and 4, in order to make the clamping device 220 more stable to the pin clamping, a reinforcing plate 223 is further included, and the reinforcing plate 223 is fixed to the bottom of the clamping device 220 to make the clamping arm 222 rotate more stably; further The base 231 is provided with a recess 233, and the depth of the recess 233 is less than or equal to the thickness of the reinforcing plate 223, so that the clamping device 220 can slide in the groove and does not affect the rotation of the clamp arm.

When the invention is in use, the clamping device 220 is reciprocated by the driving device 210. In the initial position, the clamping portion is opened due to the action of the rectangular parallelepiped through hole of the pin feeding base 230, and the pin receives the pin through the pin feeding tube. Feeding into the clamping portion, the driving device 210 slides the clamping device 220 along the rectangular through hole, removes the rectangular parallelepiped through hole, the clamping arm 222 has no pressing force, the clamping portion is clamped, and the pin is sent to the clamping device 220 to the pin After the assembly is completed, the driving device 210 pulls back the clamping device 220. The clamping portion is directly separated from the pin by the pulling force of the driving device 210, and the clamping arm 222 enters the rectangular through hole, and the clamping portion is opened.

In order to make the clamp arm 222 enter the rectangular parallelepiped through hole more smoothly, the end of the clamp arm 222 close to the rectangular parallelepiped through hole is provided with a curvature. In addition, the wrapping angle of the clamping portion of the clamping device 220 to the pin shaft is greater than 180° and less than 330°, so that the stability of the clamping device 220 to the pin shaft clamping can be ensured, and the separation can be made smoother.
