The tool holder ejection device in the claw pulling mechanism can generate thrust to overcome the bonding adhesive force generated between the tool holder body and the transition body of the ram, thereby completing the dismounting process of the tool holder body by means of self gravity.
Description
Technical Field
The invention relates to the field of machine tools, in particular to a tool holder ejection device in a claw pulling mechanism.
Background
At present, in order to enhance the composite function of a tool rest and increase the working efficiency, a plurality of machine tool manufacturers increase tool magazines so as to reduce the replacement time of tools. Generally, machine tools with small bearing capacity adopt ISO50 or BT50 taper shanks as medium devices for replacing cutters, and for machine tools with large bearing capacity, because the cutting force requirement of a tool rest is large, the common taper shank type tool changing mode cannot meet the use requirement of the machine tools, the claw pulling mechanism is applied as a convenient option. Draw claw mechanism to the taut effect of cutter holder obvious, and can bear great cutting force, nevertheless because the effect of power, the cutter holder body produces the laminating viscous force with the transition body of ram easily for under drawing the claw state of relaxing, the cutter holder body still can't be dismantled, need draw the claw back of relaxing, produce thrust in the transition body and overcome this laminating viscous force, this release mechanism that just needs a kind of power satisfies the dismantlement demand of cutter holder body.
Disclosure of Invention
In order to overcome the defect that the tool holder body cannot be detached after the pull claw of the conventional pull claw mechanism is released, the invention provides the tool holder ejection device in the pull claw mechanism.
The technical scheme of the invention is as follows: the utility model provides a draw cutter holder ejecting device in claw mechanism, includes transition body, cutter clamp body, and the transition body is fixed at the ram tip, the downthehole ejection mechanism that is fixed with in transition body center, ejection mechanism includes ring flange, ejector pin, and the ring flange passes through the screw connection on the transition body, is equipped with the spring between ejector pin one end and the ring flange, and the other end and the contact of cutter clamp body, ring flange end connection have the gland, and the gland carries on spacingly to the ejector pin.
The outer surface of the ejector rod is provided with a boss, and when the ejector rod is ejected out by the elastic force of the spring, the gland is pressed on the boss.
And a detection switch is arranged on the contact surface of the transition body and the knife clamp body.
And a claw pulling mechanism is connected between the transition body and the tool holder body.
The tool holder body is connected with an end cover, and the end cover is matched with the pull claw mechanism.
The invention has the following beneficial effects: by adopting the scheme, when the tool holder body needs to be detached, the ejection mechanism can generate downward thrust to overcome the bonding adhesive force between the tool holder body and the transition body of the ram, and the tool holder body is separated from the transition body under the action of self gravity, so that the detachment process of the tool holder body is completed, the ejection requirement of the tool holder body for automatically replacing the tool holder is met, and the tool holder is simple in structure, safe and reliable.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is an enlarged view of the ejection mechanism.
In the figure, 1-a transition body, 2-a claw pulling mechanism, 3-an end cover, 4-a cutter clamp body, 5-an ejection mechanism, 6-a detection switch, 7-a clamping screw, 8-a flange plate, 9-a compression screw, 10-a gland, 11-an ejector rod and 12-a spring.
Detailed Description
The invention is further described below with reference to the accompanying drawings:
as shown in fig. 1 and 2, the tool holder ejection device in the pull claw mechanism comprises a transition body 1 and a tool holder body 4, wherein the transition body 1 is fixed at the end part of a ram, an ejection mechanism 5 is fixed in a central hole of the transition body 1, the pull claw mechanism 2 is connected between the transition body 1 and the tool holder body 4, the pull claw mechanisms 2 are uniformly distributed on the end surface of the transition body 1, an end cover 3 is connected to the position, corresponding to the pull claw mechanism 2, on the tool holder body 4 through threads, and the end cover 3 is matched with the pull claw mechanism 2 and can bear enough tension.
The ejection mechanism 5 comprises a flange plate 8 and an ejector rod 11, the flange plate 8 is connected to the transition body 1 through a screw 7, a counter bore is formed in the center of the flange plate 8, the ejector rod 11 is located in the counter bore in the center of the flange plate 8, a spring 12 is arranged between one end of the ejector rod 11 and the flange plate 8, and the other end of the ejector rod is in contact with the tool holder body 4. The end part of the flange plate 8 is connected with a gland 10, the outer surface of the ejector rod 11 is provided with a boss, the gland 10 can limit the ejector rod 11 through the boss, namely, when the ejector rod 11 is ejected under the elastic force of the spring 12, the gland 10 can be tightly pressed on the boss. And a detection switch 6 is also arranged on the contact surface of the transition body 1 and the cutter holder body 4.
When the claw pulling mechanism 2 is in a tensioning state, the tool holder body 4 is tightly pressed on the ejector rod 11 in the ejection mechanism 5, the ejector rod 11 is displaced inwards under the action of pressure, the spring 12 is extruded to deform, and outward thrust is generated, but the thrust is tightly limited by the claw pulling mechanism 2. When the cutter holder body needs to be disassembled, the pull claw mechanism 2 is separated from the locking relation with the end cover 3 under the action of hydraulic oil, the force generated by the deformation of the spring 12 in the ejection mechanism 5 is released, the ejector rod 11 is pushed to move outwards, the cutter holder body 4 moves downwards under the pushing of the ejector rod 11, the cutter holder body 4 overcomes the adhesion viscous force, the transition body 1 is separated under the action of self gravity, and the disassembling process of the cutter holder is completed.
