Specific embodiment
The utility model is further illustrated below by way of specific embodiment:
As shown in Figure 1, Figure 2 and shown in Fig. 4, a kind of floating punch drill is from top to bottom successively arranged for connecting with bench drill
Connector, the floating platform for offsetting lateral stress and the drill bit for being punched out 300.
The floating platform includes rectangular outer cover 100, which has opening directed downwardly, which opens
Mouth is installed with bottom plate 101 on end face, which is connected and fixed by bolt and 100 open end of outer cover, the fixation bottom plate
Four balls 102 for surrounding 101 center of bottom plate and being spaced apart with predetermined distance are equipped at 101 upper surface, to constitute
Second ball platform.
It is from top to bottom successively arranged top plate 103 and float plate 200 inside the outer cover 100, the shape and outer cover of the top plate 103
100 inner cavity is adapted, and the roof 104 of the outer cover 100 is equipped with surround roof center and be spaced apart with predetermined distance four
A bolt hole, leveling bolt 107 pass through the bolt hole and offset with the upper surface of top plate 103, and the lower surface of the top plate 103 is equipped with
Four balls 102 for surrounding roof center and being spaced apart with predetermined distance, to constitute the first ball platform, the float plate
200 are located between the first ball platform and the second ball platform.
The float plate 200 is rectangular, inner cavity undersized of the size than outer cover 100, every side wall of the float plate 200
Both ends are equipped with the bolt hole for facing outer cover inner wall, and elastic spring 201 is fixed by bolts on bolt hole, as shown in figure 3, should
Elastic spring 201 is Z-shape, is made of the first support chip 202 and the second support chip 203 being parallel to each other, wherein the first support
Piece 202 is fixed by bolts on the side wall of float plate 200, and the inner wall of the second support chip 203 and outer cover 100 offsets.
Mounting hole 109 is equipped at the center of the float plate 200, drill bit 300 passes through the fixing bolt across the mounting hole 109
110 are connected to the bottom of the float plate 200, which is equipped with the aperture 108 more bigger than 300 outer diameter of drill bit, drill bit 300
It is extended downwardly at aperture 108 from from the bottom plate 101, the bottom of the drill bit 300 is equipped with drilling rod 301.
The connector is set on the cylindrical body portion 105 of 104 upper surface of roof, which is in the roof 104
Center, the leveling bolt 107 are distributed around the cylindrical body portion 105.
In use, the cylindrical body portion 105 is connected with the grappling fixture of bench drill, driving bench drill moves down to be bored for spinning head
Hole can be carried out certain sliding, therefore in floating platform since the float plate 200 is located between ball platform
In 200, the vibration of bench drill will be converted into the in-plane displancement of float plate 200, and since the float plate 200 is by being located at its week
What elastic spring 201 and outer cover inner wall at wall offseted, the displacement cross force of float plate 200 is most of by elastic spring 201
Deformation power is offset, and finally since drill bit 300 is directly to be connected with float plate 200, cross force is by elastic spring 201
After counteracting, the cross force being finally applied directly on drilling rod 301 is greatly reduced, to reduce the possibility of drill rod breaking, is mentioned
High reliability, carries out improving whole working efficiency.
In addition, not neat so that float plate 200 alice occurs or swings up and down to avoid installing because of ball individual difference exclusive or
The case where, the utility model can also allow user by using the leveling bolt 107 to offset with top plate to locating for ball
Plane is finely adjusted, and then is eliminated float plate alice or the phenomenon that swing up and down, improved use reliability.
More than to sum up, the utility model reduces the probability of drill rod breaking compared to existing punching drill bit, improves reliable
Property, and then improve working efficiency when drilling.
But those of ordinary skill in the art it should be appreciated that more than embodiment be only with illustrating this reality
With novel, and it is not used as the restriction to the utility model, as long as in the spirit of the utility model, to above
Variation, the modification of the embodiment will all be fallen in the Claims scope of the utility model.
