Abstract
Three jaw self-centering electric chucks, gear is fixedly connected with parcel, helical grooves are machined on parcel, it is meshed with the helical protrusion on slide, slide is inserted into the guide groove of disk body, and upper end is fixedly connected with claw, and disk body is fixedly connected with machine tool chief axis, baffle ring is stuck in the outside of parcel, is fixed on disk body.Machine tool body is equipped with micromotor device, motor driven gear rotation, and parcel is passed in and out with movable slider along the guide groove on disk body, to realize claw to workpiece release and pinching action.The material of disk body is No. 45 steel.Disk body replaces HT250 cast iron using No. 45 structural steel, greatly reduces disk body thickness, saves material, reduces manufacturing cost.The utility model has the beneficial effects that it is easy to operate, the operating time is saved, is improved work efficiency, cost is reduced, maintenance and maintenance are also very convenient.
Description
Technical field
The utility model relates to a kind of chuck of machine tool, in particular to three jaw self-centering electric chucks of a kind of lathe.
Background technique
Chuck is the mechanical device for being used to clamp workpiece on lathe.Utilize the radial direction for the movable jaw being evenly arranged on chuck body
It is mobile, the machine tool accessories of Workpiece clamping and positioning.Chuck is typically mounted on lathe, cylindrical grinder and internal grinder and uses,
It can also cooperate with various indexing means, be used for milling machine and drilling machine.It can be divided into from chuck jaw number: two-jaw(ed)chuck, three-jaw card
Disk, chuck, six dog chucks and special chuck.Scroll chuck in the prior art is mostly mechanical chuck, mechanical chuck
Volume is thick, and weight is big, and manufacturing expense is high, and using manually clamping workpiece, production efficiency is low, and labor intensity is big.
Utility model content
The technical issues of the utility model is solved is customer service the deficiencies in the prior art, and it is electronic to provide a kind of three jaw self-centerings
Chuck.
The technical solution adopted in the utility model is three jaw self-centering electric chucks, and gear is fixedly connected with parcel, parcel
On be machined with helical grooves, be meshed with the helical protrusion on slide, slide is inserted into the guide groove of disk body, and upper end and claw are solid
Fixed connection, disk body are fixedly connected with machine tool chief axis, and baffle ring is stuck in the outside of parcel, is fixed on disk body.Machine tool body is equipped with
Micromotor device, motor driven gear rotation, parcel is passed in and out with movable slider along the guide groove on disk body, to realize claw
To workpiece release and pinching action.
The material of disk body is No. 45 steel.Disk body replaces HT250 cast iron using No. 45 structural steel, subtracts disk body thickness significantly
It is few, material is saved, manufacturing cost is reduced.
The utility model has the beneficial effects that easy to operate, save the operating time, improve work efficiency, reduce at
This, maintenance and maintenance are also very convenient.
Detailed description of the invention
Fig. 1 is the three jaw self-centering electric chuck main views of the utility model；
Fig. 2 is the cross-sectional view of Fig. 1.
In the figure, it is marked as 1- gear, 2- parcel, 3- slide, 4- disk body, 5- claw, 6- baffle ring
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.The electronic card of three jaw self-centerings as depicted in figs. 1 and 2
Disk, gear 1 are fixedly connected with parcel 2, are machined with helical grooves on parcel 2, are meshed with the helical protrusion on slide 3, slide 3
It is inserted into the guide groove of disk body 4, upper end is fixedly connected with claw 5, and disk body 4 is fixedly connected with machine tool chief axis, and baffle ring 6 is stuck in parcel
2 outside is fixed on disk body 4.Machine tool body is equipped with micromotor device, and motor driven gear rotation, parcel, which drives, to be slided
Block is passed in and out along the guide groove on disk body, to realize claw to workpiece release and pinching action.
The material of disk body 4 is No. 45 steel.Disk body replaces HT250 cast iron using No. 45 structural steel, subtracts disk body thickness significantly
It is few, material is saved, manufacturing cost is reduced.
