Description

one

The model is attuned to the machine tool industry and can be used in cutting machines.

. CaveSpN on reversible threading machine for a cutting machine, in the case of which the friction clutch and reversing mechanism 1 are placed.

The lack of a known head is its low workability.

The purpose of the invention is the expansion of technical capabilities.

This is due to the fact that the reverse mechanism is molded in the form of a ball-bearing planetary gearbox with a retarded carrier, and the body is a caaS head {a step for interacting with the frame.

The drawing shows a schematic head.

It has a housing 1, in the hole of which the ball bearing is mounted 2. In the hole of the ball bearing 2 enters a shishndri Eska, a neck stack {step 3, in a spline (or keyway)

2

The hole of which includes the slotted (or “full”) end of the drive shaft 4. At the same end of the running shaft, there is a drive half coupling 5 of the forward stroke and is secured with a washer 6 with a screw. The cover 7 with screw 8 is fastened to housing 1 and rests on the outer ring of a ball-rim 2. The nut 9 is screwed onto the threaded neck of the drive shaft 4 and through the sleeve 10 when it is screwed into the ball-head 2 body 3 to the glass 3, the radar gun is pressed into the glass 3, the radar is drawn into the glass 3, and the cord is attached to the glass 3, the cord is routed, and the cord is attached to the glass 3, 3, the radar gun is attached to the glass 3, the radar, and the cord is attached to the glass 3, 3, the outer cover of the ball pod 2 to the glass 3, the radar, and the cord, is attached to the glass 3, 3, the outer cover of the ball pod 2 to the glass 3, the outer radar 4, the radial of the pod 2, is fixed to the glass 3, the outer radius of the radial pod 2, 3, to the glass 3, is attached to the barrel 3 of the outer shaft 4, to the glass 3, fixed in glass 3, and the inner ring - on the neck of the leading coupling half 12 reverse. Under the inner ring of the bearing 11, a thrust ball holder 13 is installed. Krypika 14, whose fingers of the lead are ground: in the space between the balls of the bearing 11, is attached to the body 1 with screws 15. The shank of the double-sided coupling half (driven shaft) 16 enters the hole in the cover 14. the driven half coupling 16 is fitted with a tap holder 17 fixed by a pin 18. Lever 19 is attached to housing 1. Reversing is reversed {зна means the head of the workpiece: tiller 1 Кон Кон Кон Conical shaft of the drive shaft 4 insert into the spindle In the machine, the lever 19 rests on the machine stand, the arB WWk6flep rafeftii is installed and the sleeve with the tap is closed. The rotation from the machine tool is transmitted to the drive shaft 4 heads and through a joint (or keyway) connection to the drive coupling half 5 of the direct drive / stroke and glass 3. The ball bearing ring Tl, fixed in glass 3 laypyitaiw, transfers the bearing ball to the rotation wheel. Rotating around its axis and not being able to rotate around the axis of the bearing, the balls are per (give the rotation of the inner bearing ring Not fixed on the inner bearing ring of the driving half coupling 12 reverse. - V, Thanks to parasitic elements (balls), the inner bearing ring 11 from the leading coupling half 12 will be in the direction opposite to the direction of the cup 3 and, consequently, the leading coupling half 5 of the forward stroke. When moving the spindle of the glass with the reversible die-cutting head down (for threading), the friction surfaces of the drive half coupling 5 of the forward stroke and the driven two-sided coupling half close. When moving the spindle of the glass up (for removal of the tap), the friction fastener 01 | the stroke and the driven two-way half coupling 16, while the tap-holder with the tap changes 716736 direction of rotation. The gap between the washer 6, the leading half coupling 5 of the forward stroke, the cup 3, the bearing 2 and the sleeve 10 is eliminated by a nut 9. During the return stroke, the tension required in the bearing elements And is adjusted by the screw 8 of the shaft 7, the bearing 2, cup 3, bearing 11, thrust pod11ShpNIK 13, cover 14, screw 15 and case I. The reactive torque transmitted to the case t from the ball bearing balls 11 through the finger of the cradle 14 and the cover 14 is intensified by the moment from force. Emerging at the free end of the lever 19 from the frame of the machine. About rmu la and 3 rev s e n i Reverse threading head to a machine tool, in the case of which a friction clutch and reversing mechanism are placed, which, in order to expand technological capabilities, the reversing mechanism is designed as a ball bearing planetary the gearbox with braked water and the head body is equipped with a cable for interacting with the machine bed.

Claims (1)

Reversible die head works ^g slodutoschym "way. ' The tapered shank of the drive shaft 4 is inserted into the bore of the spindle of the drilling machine, the lever 19 abuts against the stand of the machine, and a sleeve with a tap is fixed to the “a”. Rotation from the machine spindle is transmitted to the drive shaft 4 of the head through a spline (or key) connection - to the driving half-coupling 5 of the forward / reverse cup 3. The outer ring of the ball bearing 1Ϊ- fixed in the cup 3 rotates and rotates the bearing balls. Rotating around its axis and not being able to rotate around the axis of the bearing, the balls transmit rotation to the inner ring of the bearing 11 and the drive back coupling half 12 fixed in the inner ring of the bearing. · „Thanks to spurious elements (balls), the inner ring of the bearing 11 with the driving coupling half 12 will rotate in the direction opposite to the direction of the cup 3 and, therefore, the driving coupling half 5 of the forward stroke. When moving the spindle of the cup with the reversible thread-cutting head down (for threading), the friction surfaces of the leading coupling half 5 of the forward stroke of the driven double-sided coupling half 16 are closed. When the cup spindle is moved up (for ³⁰ tap removal), the friction surfaces of the leading reverse coupling half 12 and the driven two-way half coupling 16 are closed, while the counter-tap with the tap 716736 4 has the direction of rotation. 6, the leading coupling half 5. which 3, bearing 2 The clearance between the forward stroke washer and the flange by the sleeve 10 is eliminated by the nut 9. During the reverse stroke, the tightness in the elements of the bearing 11 necessary for transmitting torque is adjusted by screws 8 through the cover 7, bearing 2, cup 3, bearing 11, thrust bearing 13, cover 14, 15 screws and 1 'housing The reactive torque transmitted to the housing I from the balls of the ball bearing 11 through the fingers of the leash of the cover 14 and the cover 14 is balanced by the moment arising from the force arising at the free end of the lever 19 from the machine frame. A reversible thread-cutting head to a metal-cutting machine, in the case of which a friction clutch and a reversing mechanism, differing in? M, are placed, which, in order to expand the technological capabilities of ²⁵ capabilities, the reversing mechanism is made in the form of a ball-bearing planetary gear with a braked carrier, and the head housing is equipped with a lever for interacting with the machine bed.
