In this embodiment, the position limiting cap 50 is assembled with the first clamping piece 20, the second clamping piece 30 and the torsion spring 40 at the same station; in other embodiments, the position limiting cap 50 may be assembled by a single station, a single process, or manually; in other embodiments, instead of the limiting cap 50, the end of the frame rod 101 may be pressed to form a limiting portion to limit the falling of the clip.

The process of the automatic clothes hanger clamp assembling equipment 100 for fixing the clamp and the limiting cap 50 on the hanger body 10 at the assembling station is as follows: the first clamping piece 20 and the second clamping piece 30 are respectively conveyed to two clamping piece mounting seats 22 and 32 of the clamping piece opposite-pushing mechanism; the torsion spring 40 is conveyed into the receiving block 442; the limiting cap 50 is conveyed to the placing groove 510; at this time, the two clip installation seats 22 and 32 of the clip opposite-pushing mechanism move towards each other, so that the first clip 20 and the second clip 30 are butted together, and the torsion spring 40 is stamped between the two clips by the punch 42; the frame moving mechanism 12 drives the frame 10 to insert into the rod head insert 35 and to pass through the lugs 302 of the two clamping pieces and the spiral part 401 of the torsion spring 40; the limit cap push rod 52 pushes the limit cap 50 to be stamped on the end part of the frame rod 101 in an interference fit manner; the parts are reset, the frame reversing rotary table 111 drives the clamping seat 11 and the frame 10 clamped on the clamping seat 11 to rotate 180 degrees on the horizontal plane, so that the other end of the frame rod 101 is aligned to the assembling station, and the process is repeated, and the assembly of the clamp and the frame 10 is completed.

As can be seen from the above description of the specific embodiment, the torsion spring conveying device 4 of the clothes hanger clamp according to the present invention extrudes the two torsion bars 402 of the torsion spring 40 to elastically deform before conveying the torsion spring 40 to the assembly station, and pushes the spiral portion 401 of the torsion spring 40 by the punch 42 to push the torsion spring 40 in the elastically deformed state to the assembly station, so as to reduce the difficulty of assembling the torsion spring in the assembly station in cooperation with other components, and improve the production efficiency and yield. The automatic assembling equipment 100 for the clothes rack clamp comprises a rack body conveying device 1, a first clamping piece conveying device 2, a second clamping piece conveying device 3, a torsion spring conveying device 4 and a limiting cap conveying device 5, all the parts are conveyed and assembled together automatically, the automation degree is high, and the production efficiency of the clothes rack clamp is greatly improved.

The above description is only for the specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention.
