Accompanying drawing is a structural representation of the present utility model.
Wherein: 1, support, 2, sliding axle, 3, cylinder, 4, control valve, 5, clamp adjustable mechanism, 6, fixture block, 7, left and right adjusting mechanism, 8, pressure head, 9, the angle micro-adjusting mechanism, 10, base.
The specific embodiment
As shown in drawings, clamping device of the present utility model comprises base 10, support 1, pneumatic clamping mechanism, clamps adjustable mechanism 5 and left and right adjusting mechanism 7.Left and right adjusting mechanism 7 is installed on the base 10, and support 2 is installed on the left and right adjusting mechanism 7 on the base 10, and in effect lower carriage 2 move left and right on the guide rail of base 10 of left and right adjusting mechanism 7, left and right adjusting mechanism 7 adopts spiral travel mechanisms.The effect of left and right adjusting mechanism 7 is the positions, the left and right sides that are used for adjusting pressure head 8 and coil solder joint, drives support 2 and upper-part move left and right thereof by hand screw rod.
Clamp the bottom surface that adjustable mechanism 5 is installed in base 10, its effect is that whole clamping device is fixed on the armature spindle, and fixture block 6 is installed below, convenient and flexible installation, enough clamping forces is arranged.Because the groove of leaving on the armature spindle is along the circumference radial distribution,, guarantee to be fit to groove angle radially by rotatable U type supporting and the axle that clamps on the adjustable mechanism 5 so adapt to separation by the fixture block of removable adjustment.
Sliding axle 2 vertically is installed in the support 2, can in support 2, move forward and backward, the front end of sliding axle 2 is equipped with pneumatic clamping mechanism, this pneumatic clamping mechanism is made up of cylinder 3, control valve 4 and pressure head 8, the air inlet/outlet of cylinder 3 and control valve 4 are connected by pipeline, and pressure head 8 is installed in the piston rod end of cylinder 3.The compressed air that this pneumatic clamping mechanism working pressure is 0.5～0.8MPa is as power source, the stroke of cylinder 3 is 200mm, according to the needed cylinder bore of soldering calculation of pressure of soldering processes, control valve 4 is the two-position five-way hand-operated direction valve, the control breakdown action.
The effect of sliding axle 2 parts is that pressure head can be moved forward and backward, from first coil in last coil distance, thereby can guarantee the welding of whole rotor coil.Placed linear bearing in support 2, sliding axle will have enough intensity, to guarantee to bear the pressure of cylinder 3.Determine the length of sliding axle 2 to the distance of a last coil according to first coil.
Angle micro-adjusting mechanism 9 is installed on the support 1, its function is to be used for adjusting more accurately the circumferential locations of pressure head 8 and coil solder joint, mainly plays the angle adjustment effect, has guaranteed the consistent of pressure head and welding position.Angle micro-adjusting mechanism 9 also adopts spiral travel mechanism, realizes by screw rod and nut.
