The utility model will be described in detail by embodiment below.
Plunger is arranged on the top of the shank 1 in a kind of floating pin, including shank 1, shank fixation hole 2 and shank baffle 3
4, plunger groove 5 is set between the plunger 4 and shank 1, the plunger groove 5 is radially-inwardly recessed along 4 bottom of plunger,
Pin shaft 6 is additionally provided between the plunger 4 and shank 1, the pin shaft 6 is the smooth cylindrical structure in surface, 6 edge of pin shaft
Shank 1 is inserted radially into shank 1, and the cylinder side wall of pin shaft 6 can expose in plunger groove 5.
Specifically, the plunger groove 5 has trench bottom surfaces 51, material strip 9 is usually taken and is set in trench bottom surfaces 51, in plunger
It is moved in groove 5, bottom surface slot 52 is provided in the trench bottom surfaces 51, the bottom surface slot 52 is radial logical along trench bottom surfaces 51
To the semi-circular cross-section groove in 51 center of circle of trench bottom surfaces, pin shaft 6 is inserted into the bottom surface slot 52, and the trench bottom surfaces 51 have
There is the outer groove 521 being exposed in plunger groove 5, and be deep into the inside groove 522 inside shank 1, likewise, when pin shaft 6 is inserted into
To after the bottom surface slot 52, it may have expose in the exposed parts in plunger groove 5 and the insertion section being inserted into inside shank 1
Point.When material strip 9 is usually taken set moved in trench bottom surfaces 51 when, the pin shaft 6 will play the role of idler wheel, at the bottom
It is rolled in face slot 52, the line for being transformed to material strip 9 between material strip 9 and pin shaft 6 with the face contact of trench bottom surfaces 51 contacts, and subtracts significantly
The friction between material strip 9 and plunger groove 5 and noise are lacked.Further, it is also set between 52 upside of the pin shaft 6 and bottom surface slot
It is equipped with gap 53, further reduces the friction between pin shaft 6 and bottom surface slot 52.
Specifically, also setting up fixation hole 7 at the top of the plunger 4, it is additionally provided with fixing piece 8 in the fixation hole 7,
The fixing piece 8 is inserted into the fixation hole 7, and one end of the fixing piece 8 is against the insertion that pin shaft 6 is inserted into inside shank 1
On part, so that the bottom of the fixing piece 8 is contacted with pin shaft 6, pin shaft 6 is removably secured to by fixing piece 8
On shank 1.
Further, also set up annular groove 61 on the insertion portion of the pin shaft 6 so that the bottom of the fixing piece 8 with
When pin shaft 6 contacts, the bottom of the fixing piece 8 can be placed in the annular groove 61.Since pin shaft 6 is in rotation, due to vibration
Movement is used and the shaking of material strip itself, pin shaft 6 can be made to have a case that move generation to the outside of bottom surface slot 52, with the time
Passage, the meeting moved outside pin shaft 6 is more obvious, so that pin shaft 6 has the risk for dropping out bottom surface slot 52.It, will in the utility model
Annular groove 61 is set on the insertion portion of pin shaft 6, and the bottom of fixing piece 8 is placed in the annular groove 61, is thus played
The effect for preventing pin shaft 6 from translating, greatly reduces the risk that pin shaft 6 drops out bottom surface slot 52.
Further, described 8 one end of fixing piece can be arranged on circlip 73, in this case, in the fixation
The first fixing groove 71 and the second fixing groove 72 is respectively set in the two sides in hole 7, so that holding is fixed on institute respectively at the both ends of circlip 73
It states in the first fixing groove 71 and the second fixing groove 72, the top of the fixing piece 8 is against in the spring body of the circlip 73.Further
, it can be by the length of the setting fixing piece 8, so that circlip 73 has downward elastic force to fixing piece 8, so that fixing piece
8 can more steadily holding in annular groove 61.
Further, the fixing piece 8 can be arranged on plug screw 74, and the hole got through is arranged on plug screw 74, so that
Fixing piece 8 is mounted on plug screw 74 by the hole.In this case, the top of fixation hole 7 is provided with plug screw 74, it is described solid
The top for determining part 8 is against on plug screw 74, can be realized by adjusting position of the plug screw 74 in fixation hole 7 to the tight of fixing piece 8
Gu and the function of loosening.
Further, two floating pins provided by the utility model are oppositely arranged, in the plunger groove 5 of two floating pins
Between take and set material strip 9, that is, a set of floating pin guide system is formed, when the material strip 9 is transported in the plunger groove 5 of two floating pins
When dynamic, since the lower part of plunger groove 5 is provided with the pin shaft 6 that can be rotated, the material strip 9 is substantially the rotation in pin shaft 6
Under be carried forward transmission, substantially reduce the friction between material strip 9 and plunger groove 5 in this way, realize the bottom by plunger groove 5
Frictional drive is optimized for pin shaft rotation transmission, solves the wear problem of feeding friction noise and floating pin.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent substitution, improvement and etc. done should be included in the utility model
Within the scope of protection.
