description

When raging polygonal parts and castle nuts in large-scale series production it has so far been found annoying that the mech. Dividing attachments still have to be operated manually for clamping and filing, for this reason I developed one Device that combines a pneumatic clamping device and a pneumatic dividing device in one housing. The device can be included semi-automatically in the workflow of the respective machine.

Me puncture of the device is divided:;

1. Into the pneumatic tension. \

2. In the pneumatic sub-device.

1, tension

Me pneumatic clamping device for collets consists of a cylinder (b) rotatably mounted in the housing (a), dör in its front part accommodates the pressure sleeve (c). The union nut (d) is screwed on from the outside. The clamping cylinder becomes radial on its outer diameter by two O-rings sealed to the housing. The air supply for the clamping cylinder is located in the housing between the O-rings. At the From here, the compressed air flows into the grooves around the cylinder (b) and through the bore (e) under the tensioning piston (f), which applies the pressure via the pressure sleeve (e) to the clamping process Collet transmits. When releasing: (venting) press the Springs (g) return the tensioning piston to its starting position. Of the The clamping process is actuated via a three-way valve. _ -.,:

2. Filing facility :

The hollow spindle (h) and the graduated disk (i) are on the Base plate Q) of the clamping cylinder flanged on. On the Hollow spindle (h) is the gearwheel (k) with its face Coupling teeth rotatably and axially displaceably mounted. The frontal side The toothed coupling ring (1) is connected to the hollow spindle (h) on a feather key. The index facility consists of the index cylinder (m) -, the piston (n) with the Index bolt and the shift fork (o), which are inserted into the grooves of the Gear (k) engages. The piston (n) is coupled to a three-way valve spool (p) and the base piece (q.) Of the index cylinder also serves as its valve housing. The V Both holding cylinders (r and r 1) are guided in the housing (a) and flanged. Their piston rods (s and s Ϊ) grip with their = Toothing in the gear (k). The pistons: (t and t1> are pressed onto the piston rods, ■

Claims (4)

P.A, 27159e * 2if.L63: The piston rod (s 1) is bored and takes up the return spring (u), which is guided through a miter rod (v) from the side of the housing. The Reyolveransehlag is located opposite the switching cylinder (r). The stop shaft (w) carries the stop bolts (x) on its head piece for the possible divisions in the device. The shaft of the stop shaft (w) is designed as a three-way valve slide. Me guide bushing (y) also serves as valve housing and is flanged to housing (a). It also takes the locking bolt (z) with spring, which fixes the set pitch in the respective center of a stop bolt, and the eückholbolzen (al) with leather to retract the stop shaft. The adjusting ring (bi) is clamped onto the stop shaft and has engraved the possible divisions in the device on its outer diameter. By turning the adjusting ring, the number of the required division must be brought into line with the line mark on the miter bushing. Control sequence A control pulse from a three-way valve reverses the main control valve (el) and initiates the automatic pole control. The upper side of the index piston is pressurized via the main control valve (el) and the lower side is vented, whereby the gear wheel (k) is brought into engagement in the coupling ring (1) with the aid of the switching table (o). The two switching pistons (tu. t 1) are acted upon via the three-way valve (p), with the sub-spindle performing the division set on the turret stop. When the piston rod (s) hits the stop pin (x) in the working position, it actuates the stop shaft, which is designed as a three-way valve, whereby an air pulse reverses the main control valve (el). The lower side of the index cylinder is acted upon by the main control valve (el) and its upper side is vented. During this process, the gear wheel (k) is disengaged from the coupling ring (1) and the index plate (i) is locked in place by the index bolt The return spring (u) is vented and the pistons are pushed back to their original position. The switching process can be initiated again from the disconnection * zap rubble, claim (utility model) 1.) Preßluftbetätigfeer Zangenspannstoek with automatic dividing device, characterized in that the clamping piston door clamps the pliers into the frontally toothed work spindle is included. 2.) Air-operated collet vice with automatic part device, characterized in that a Hevolver flange shaft with three-way reversing valve installed which is provided with a dial on which the possible divisions in the device are engraved. 3) Compressed air operated collet vice with automatic: dividing device, characterized in that the switching mechanism τ is operated by two cylinders working in opposite directions. 4.) Air-operated collet vice with automatic dividing device, characterized in that the index piston (h) couples the sliding wheel (k) to the sub-spindle. :
