Abstract
The utility model discloses a chuck of machine tool, including base and looping -in seat, the looping -in seat sets up on the base surface, the base bottom surface is equipped with two symmetrical spouts, the base is placed on two slide rails corresponding with the spout through the spout, set up three hydraulic pressure mounting hole along its circumference on the looping -in seat, and three hydraulic pressure mounting hole is equilateral triangle and distributes, all be provided with the hydraulic stem in the three hydraulic pressure mounting hole, the output shaft of three hydraulic stem is all towards looping -in seat center, the tip that the looping -in seat was kept away from to the output shaft of three hydraulic stem all is connected with the cardboard. This chuck of machine tool steps up the article through the hydraulic stem when using, and the hydraulic stem has firm output and the big function of clamping -force volume, the device simple structure, and the centre gripping is stable and firm, has solved traditional lathe chuck and has probably pressed from both sides not firm foundry goods, leads to the work piece to squint often to make the foundry goods not hard up problem appear.
Description
Technical field
The utility model relates to machine chuck technical field, is specially a kind of chuck of machine tool.
Background technology
Traditional chuck is generally made up of chuck body, movable jaw and claw driving mechanism part, is that a kind of utilization is distributed on moving radially of movable jaw on chuck body, the machine tool accessories of Workpiece clamping and location.There are through hole in chuck body central authorities, to pass through workpiece.Chuck is usually arranged on lathe, cylindrical grinder and internal grinder and uses, and also can coordinate with various indexing means, for milling machine and drilling machine.In process, along with lathe spindle drives foundry goods High Rotation Speed, the cutter added on upper tool post also carries out cutting movement to foundry goods simultaneously, it is insecure that traditional claw there will be holding workpiece, and chuck probably presss from both sides loosely foundry goods, often causes workpiece variation, thus make foundry goods occur the phenomenon loosened, affect the machining accuracy of foundry goods, for this reason, we propose a kind of chuck of machine tool.
Utility model content
The purpose of this utility model is to provide a kind of chuck of machine tool, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of chuck of machine tool, and comprise base and annular mount pad, annular mount pad is arranged on susceptor surface, base end face is provided with two symmetrical chutes, and base is placed on two slide rails corresponding with chute by chute.
Annular mount pad arranges three hydraulic installalion holes along its circumference, and three hydraulic installalion holes are equilateral triangle distribution, hydraulic stem is provided with in three hydraulic installalion holes, the output shaft of three hydraulic stems is all towards annular mount pad center, and the output shaft of three hydraulic stems is all connected with clamp away from the end of annular mount pad.
Preferably, clamp is circular arc, and when three hydraulic stems are all in the longest, now three circular arc cards are spliced into annular soon mutually.
Preferably, annular mount pad is supported by pole by base dual-side.
Preferably, pole and annular mount pad are structure as a whole.
Compared with prior art, the beneficial effects of the utility model are: this chuck of machine tool in use, by hydraulic stem, object is stepped up, hydraulic stem has stable output and function that gripping strength is large, this apparatus structure is simple, and clamping is stable and firm, solves traditional machine chuck and may press from both sides loosely foundry goods, often cause workpiece variation, thus make foundry goods occur the problem loosened.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1, base, 2, slide rail, 3, pole, 4, annular mount pad, 5, hydraulic stem, 6, clamp, 7, hydraulic installalion hole.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model provides a kind of technical scheme: a kind of chuck of machine tool, comprise base 1 and annular mount pad 4, annular mount pad 4 is arranged on base 1 surface, annular mount pad 4 is supported by pole 3 by base 1 dual-side, pole 3 and annular mount pad 4 are structure as a whole, pole 3 can allow between annular mount pad 4 and base 1 more stable, base 1 bottom surface is provided with two symmetrical chutes, base 1 is placed on two slide rails 2 corresponding with chute by chute, dragging base 1 can make this device move along slide rail, widen the distance with machine tool.
Annular mount pad 4 arranges three hydraulic installalion holes 7 along its circumference, and three hydraulic installalion hole 7 distributions in equilateral triangle, hydraulic stem 5 is provided with in three hydraulic installalion holes 7, the output shaft of three hydraulic stems 5 is all towards annular mount pad 4 center, the output shaft of three hydraulic stems 5 is all connected with clamp 6 away from the end of annular mount pad 4, clamp 6 is circular arc, and when three hydraulic stems 5 are all in the longest, now three circular arc cards fast 6 are spliced into annular mutually.In use, stepped up by object by hydraulic stem 5, hydraulic stem 5 has stable output and function that gripping strength is large, and this apparatus structure is simple, and clamping is stable and firm.
Although illustrate and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present utility model and spirit, scope of the present utility model is by claims and equivalents thereof.
