Abstract
The utility model relates to the technical field of machine tool accessories, and provides an electric chuck which uses a torque motor to directly drive an Archimedes spiral line disk, so the racks on the back face of the claw is driven to make the claw move in the radial direction along the chuck body. Then the purpose of clamping or loosening the processed workpieces can be achieved.
Description
The utility model relates to the machine tool accessories technical field.
Chuck is the annex of machining lathe, with it workpiece to be machined is clamped, and makes the center line of processing work consistent with the machine tool chief axis centre of gyration.At present, the chuck major part of using is the mechanical type chuck, operating personnel rotate bevel pinion by spanner and drive the bevel gear wheel rotation of meshing with it, because the spiral of Archimedes dish at the bevel gear wheel back side is meshed with the tooth bar at the claw back side, thereby each claw is moved radially along chuck body, processing work is clamped or unclamp, operating personnel are not only time-consuming but also require great effort like this.Electric chuck is adopted by people thereupon, at existing electric chuck because other parts are many, complex structure, and the machine tool chief axis endoporus is equipped with power transmission shaft, so workpiece to be machined can not be sent into from lathe spindle hole rear portion, particularly incompatibility adds section chief's bar.
The purpose of this utility model is in order to overcome above-mentioned shortcoming, designs a kind of simple in structurely, realizes the processing work automatic card-loading, reduces labor intensity of operating staff, raises labour productivity.
To achieve these goals, the utility model proposes and a kind ofly directly drive the spiral of Archimedes dish with torque motor and rotate, drive the tooth bar at the claw back side.Claw is moved radially along chuck body, reach the technical scheme that clamps or unclamp the processing work function.
Electric chuck of the present utility model comprises by band spiral of Archimedes dish, chuck body, claw and being formed, and it is characterized in that directly being driven by the rotor of the stator that is fixed in the torque motor on the chuck body with the torque motor that is connected with band spiral of Archimedes dish with screw with the spiral of Archimedes dish.Be that the stator of torque motor is fixed in the groove on the chuck body, the rotor of torque motor is connected with band spiral of Archimedes dish with screw.Or the rotor of torque motor and chuck body are affixed, and the stator of torque motor is connected with band spiral of Archimedes dish.
Owing to adopted above-mentioned technical scheme with the direct rotating band spiral of Archimedes of torque motor dish, compare with existing electric chuck, saved complicated speed changing structure, thereby the structure of electric chuck is simplified greatly, while positioning accuracy height, enlarge the range of application of electric chuck, improved labor productivity.
Description of drawings:
Accompanying drawing is the structure chart of electric chuck.
Wherein: 1 is ring flange, and 2 is screw, and 3 is the rotor brush, and 4 is conducting ring, and 5 is brush, and 6 is power supply lead wire, and 7 is chuck body, and 8 is stator, and 9 is rotor, and 10 are band spiral of Archimedes dish, and 11 is claw, and 12 is thrust rolling bearing, and 13 is the collar.
Below in conjunction with embodiment shown in the drawings the utility model is described in detail.
The utility model is to be with the rotation of spiral of Archimedes dish 10 directly to be driven by torque motor, the stator 8 of torque motor is affixed with the groove tight fit on the chuck 7, the rotor 9 usefulness screws 2 of torque motor are connected with band spiral of Archimedes dish 10, spiral of Archimedes dish 10 relatively rotates by two radial thrust bearings, 12 location with chuck body 7, the inner ring of bearing is loaded on the central shaft of chuck body 7, the outer ring of bearing is loaded in the hole of band spiral of Archimedes dish 10, with the collar 13 separately, with snap ring and bearing cap axial restraint with two radial-thrust bearings.Chuck body 7 usefulness screws are connected with ring flange 1, and ring flange 1 is connected with machine tool chief axis in use.When torque motor when power supply lead wire 6 is connected with dc source, electric current through power supply lead wire 6, brush 5, conducting ring 4 to rotor brush 3, torque motor rotor 9 is rotated, driving spiral of Archimedes dish 10 rotates, the claw 11 that makes and be meshed with the spiral of Archimedes dish moves radially along chuck body 7, reaches chucking or unclamps workpiece to be machined.
