Abstract
An automatic fixture for processing disc workpieces with center holes belongs to machine fixtures, and is characterized in that a transitional disc is mounted in a taper hole at the front end of a spindle, one end of the transitional disc is provided with a conical handle while the other end is a positioning cone, an expansion sleeve with an inner taper hole is mounted on the positioning cone, a hydraulic power cylinder is mounted at the rear end of the spindle, a draw bar is arranged in a hole of the spindle, one end of the draw bar is connected with the hydraulic power cylinder while the other end is provided with a thrust plate, the thrust plate is fixed via locking nuts, and an end surface of the thrust plate contacts with an end surface of the expansion sleeve. The automatic fixture has the advantages of simple structure, convenient and fast use, easy and feasible adjustment, and capability of meeting processing requirements of parts with different dimensions.
Description
Technical field
The utility model belongs to jig, relates to a kind of automatic fixture of processing cellular type workpiece in the disk.
Background technology
At present, cellular type workpiece in the processing disk generally is the external diameter with traditional gripper chuck clamping of workpieces on lathe, perhaps uses chuck tensioner inner diameter of workpiece, and this clamping all is manually, also needs centering, and can not realize location and clamping automatically.If the perforate shape of carrying out on the outer circle diameter is processed, traditional chuck just holds and can't use.
Summary of the invention
The purpose of this utility model just provides the anchor clamps of cellular type workpiece in a kind of automatic location, the self-holding processing disk.
The solution that realizes the utility model purpose is to comprise main shaft 6, chuck 2, transition disc 5 particularly is installed in the taper hole of main shaft 6 front ends, one of transition disc 5 is taper shank, the other end is a locating cone, the ringfeder 13 of internal taper hole is installed on the locating cone, the rear end of main shaft 6 is equipped with hydraulic power oil cylinder 8, pull bar 7 is installed in the hole of main shaft 6, one of pull bar 7 is connected with hydraulic power oil cylinder 8, the other end is equipped with thrust button 3, thrust button 3 is fixing by locking nut 4, and the end face of thrust button 3 contacts with the end face of ringfeder 13.
Transition disc 5 also is connected with chuck 2 by bolt 11.
The utility model has the advantages that simple in structure, convenient to use, adjust feasiblely easily, and a cover jig can satisfy the part processing of different size specification.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1-workpiece, 2-chuck, 3-thrust button, 4-locking nut, 5-transition disc, 6-main shaft, 7-pull bar, 8-hydraulic power oil cylinder, 9-pine nut, 10-synchronous pulley, 11-bolt, 12-chuck jaws, 13-ringfeder.
The specific embodiment
Hydraulic power oil cylinder 8 is installed in main shaft 6 rear ends at main spindle box, a pull bar 7 that passes spindle hole is arranged, pull bar 7 one ends are connected with hydraulic power oil cylinder 8, the other end is connected with thrust button 3, thrust button 3 is fixed on the pull bar 7 by locking nut 4, one of transition disc 5 is taper shank, be installed in the taper hole of main shaft 6 front ends, and be connected with chuck 2 by bolt 11, the other end of transition disc 5 is locating cones, the ringfeder 13 of internal taper hole is installed on the locating cone, and the end face of thrust button 3 contacts with the end face of ringfeder 13, and the inner hole sleeve of workpiece 1 is on the cylindrical of ringfeder 13.
During work, workpiece 1 is installed on the ringfeder 13, when hydraulic power oil cylinder 8 when move the rear end of main shaft 6, drive pull bar 7 and move backward, pull bar 7 drives thrust button 3 and also moves backward, and thrust button 3 just promotes ringfeder 13 and moves backward, because between the locating cone of ringfeder 13 and transition disc 5 is cone match, so ringfeder 13 has certain radial displacement simultaneously in diametric(al), be exactly this slight displacement, make can be completely fixed between the workpiece 1 relative transition disc 5.And transition disc 5 is fastening by bolt 11 by conical bore location and chuck 2 with machine tool chief axis 6, and chuck 2 puts together on main shaft again; Therefore realized the synchronous fully of transition disc 3 and machine tool chief axis 6.Drive workpiece 1 and together rotate when main axis rotation, at this moment knife rest can be finished processing to workpiece according to program.Otherwise when hydraulic power oil cylinder 8 moved forward, pull bar 7 pushed away forward, drove thrust button 3 reaches, and ringfeder 13 is loosened, and throws off fully between workpiece 1 and the transition disc.
Locking nut 4 is synchronous in order to guarantee pull bar 7 and thrust button 3, and its position and degree of tightness power can be adjusted flexibly; Chuck jaws 12 is used for the chucking of other roller class workpiece; Synchronous pulley 10 on the machine tool chief axis 6 is that encoder transmission signal is used, and stop nut 9 all belongs to the normal configuration part of lathe.
The utility model only need be joined the corresponding tensioner cover 13 of size and exchange according to the interior hole size of different workpieces, can satisfy chucking all size workpiece 1.And the utility model can be installed on the numerically controlled lathe, and hydraulic system is associated with control system, and chucking loosens and can finish by program, can realize automation mechanized operation of the present utility model.
