Technical field
The utility model relates to electric spark machining field, in particular to a kind of blind rivet and the electric spark anchor clamps with this blind rivet.
Background technology
The existing employed anchor clamps of spark erosion equipment are made up of clamping fixture seat, blind rivet and chuck usually; Because blind rivet can not be realized flexible clamping; Do not reserve suitable nargin; Regular meeting makes quality of fit reduce because of the excessive mating surface excessive compression that causes clamping fixture seat and chuck of external force normally using often, and the serious anchor clamps that also can make damage.
The utility model content
The utility model aims to provide a kind of blind rivet and the electric spark anchor clamps with this blind rivet, to improve the positioning accuracy of clamping fixture seat and chuck.
To achieve these goals, an aspect according to the utility model provides a kind of blind rivet, comprising: screw, and its first end is the end of thread, second end is the chuck link; Pull bar is sleeved on the screw, and near the end of thread; Drag link sleeve is sleeved on the pull bar with a gap, and near the chuck link; And seal, be sleeved on the pull bar.
Further, be provided with first boss and second boss vertically continuously at an end of pull bar, drag link sleeve is sleeved on second boss with a gap, and the end face of the end face of drag link sleeve and first boss fits.
Further, the pull bar outer surface is provided with annular groove, and seal is installed in this annular groove.
Further, seal is an O-ring seals.
According to another aspect of the utility model, a kind of electric spark anchor clamps are provided, comprise clamping fixture seat and chuck, this clamping fixture seat is connected through blind rivet with chuck, and this blind rivet is above-mentioned blind rivet.
Further, blind rivet is connected with clamping fixture seat through the end of thread of screw.
Further, chuck is sleeved on the outside of the pull bar of blind rivet, and through seal and blind rivet interference fit.
Blind rivet according to the utility model; Be sleeved on a gap through drag link sleeve blind rivet the time can be finely tuned in tension; Avoid clamping fixture seat to occur deformed damaged under external force, in the accurate location of realizing clamping fixture seat and chuck, also help the service life that prolongs clamping fixture seat.
The electric spark anchor clamps that the utility model provides are because of having above-mentioned blind rivet, thereby the accurate location of having realized clamping fixture seat and chuck has guaranteed machining accuracy.
Description of drawings
The Figure of description that constitutes the application's a part is used to provide the further understanding to the utility model, and illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model.In the accompanying drawings:
Fig. 1 is the structural representation of the blind rivet of the utility model;
Fig. 2 is the structural representation of pull bar;
Fig. 3 is the structural representation of drag link sleeve; And
Fig. 4 is the intention of the syndeton of blind rivet and clamping fixture seat.
The specific embodiment
Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.Below with reference to accompanying drawing and combine embodiment to specify the utility model.
An embodiment according to the utility model provides a kind of blind rivet, and is as shown in Figure 1, comprising: screw 10, its first end are that the end of thread 11, the second ends are chuck link 13; Pull bar 30 is sleeved on the screw 10, and near the end of thread 11; Drag link sleeve 50 is sleeved on the pull bar 30, and near chuck link 13; And seal 70, be sleeved on the pull bar 30.
Blind rivet according to the utility model embodiment; Be sleeved on a gap through drag link sleeve 50 blind rivet the time can be finely tuned in tension; Avoid clamping fixture seat to occur deformed damaged under external force, in the accurate location of realizing clamping fixture seat and chuck, also help the service life that prolongs clamping fixture seat.
Referring to figs. 2 and 3; As can be seen from Figure 2; End at pull bar 30 is provided with first boss 31 and second boss 33 vertically continuously, and drag link sleeve 50 shown in Figure 3 is sleeved on second boss 33 with a gap, and the end face of the end face of drag link sleeve 50 and first boss 31 fits.
It can also be seen that from Fig. 2 pull bar 30 outer surfaces are provided with annular groove 35, seal 70 promptly is installed in this annular groove 35, and in the present embodiment, seal 70 adopts O-ring seals.
According to another embodiment of the utility model, a kind of electric spark anchor clamps are provided, as shown in Figure 4, the clamping fixture seat 90 of these electric spark anchor clamps is connected with an end of above-mentioned blind rivet, and particularly, the end of thread 11 of screw 10 is connected on the clamping fixture seat 90.
The electric spark anchor clamps also comprise the chuck that does not illustrate in the drawings, and chuck is sleeved on the outside of the pull bar 30 of blind rivet, and through seal 70 and blind rivet interference fit.
From above description, can find out that the utility model the above embodiments have realized following technique effect:
In the embodiment of the utility model; Blind rivet is sleeved on a gap through drag link sleeve blind rivet can be finely tuned when straining; Avoid clamping fixture seat to occur deformed damaged under external force, in the accurate location of realizing clamping fixture seat and chuck, also help the service life that prolongs clamping fixture seat.
In addition, the electric spark anchor clamps that the utility model embodiment provides are because of having above-mentioned blind rivet, thereby the accurate location of having realized clamping fixture seat and chuck has guaranteed machining accuracy.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
