Problems solved by technology

When this structure is used for chip removal of long iron chips, it is easy for the iron chips to be entangled on the spiral blade, causing problems such as unsmooth and stuck spiral chip removal; It floats on the upper end of the spiral blade, which affects the efficiency of chip removal. With the transportation of long iron chips, it is more likely to have problems such as poor chip removal

Embodiment 1

[0029] Such as Figure 1-2 As shown, a spiral chip removal device for a lathe includes a semicircular groove 1 at the bottom. The bottom of the groove 1 is covered with a steel plate with a thickness of 8 mm. A first motor 2 is installed at one end of the groove 1. The first The motor 2 is a geared motor, and a collection box 3 is placed under the other end. A screw shaft 4 is arranged in the pit 1. A screw blade 5 is welded and fixed on the screw shaft 4. One end of the screw shaft 4 is connected to the The first motor 2 is connected, the other end is not fixed, is in a free state, and is suspended on the upper side of the collection box 3, the end of the pit 1 close to the collection box 3 is inclined downward, and the inclination angle of the pit 1 is ≤5°.

[0030] The usage method of this embodiment: after the turning iron filings fall into the pit 1, the first motor 2 drives the screw shaft 4 to rotate, and the screw shaft 4 drives the spiral blade 5 to rotate, pushing th...

Embodiment 2

[0032] This implementation is basically the same as Embodiment 1, the difference is that: Figure 3-5 As shown, a semicircular groove pit 1 is made at the back of the lathe bed, and a plurality of chip inlets 7 are provided on the side wall of the screw shaft 4 close to the side of the lathe bed, and a plurality of chip inlets 7 are provided on the side wall of the other side The scraping mechanism of the transmission, the chip inlet 7 and the scraping mechanism are all arranged along the axial direction of the screw shaft 4, and the scraping mechanism includes a supporting plate 8 arranged along the axial direction of the screw shaft 4, and the supporting plate 8 is close to the side of the first motor 2 One end is equipped with driving wheel 9, and the other end is equipped with driven wheel 10, and the belt 11 of transmission is set on driving wheel 9 and driven wheel 10, and belt 11 is driven by second motor 21, and the output end of second motor 21 and driving wheel 9 A p...

Embodiment 3

[0036] This embodiment is basically the same as Embodiment 2, the difference is: as Figure 6 As shown, a torque sensor 20 is arranged between the first motor 2 and the universal joint 6, and the torque sensor 20, the first motor 2 and the second motor 21 are all electrically connected to the controller, and the controller adopts a PLC controller. The second motor 21 is a driving motor.

Abstract

The invention provides a spiral chip removal device and chip removal method for a lathe. The chip removal device comprises a groove pit of which the bottom is semicircular. A steel plate is pasted and wrapped to the bottom of the groove pit. A first motor is arranged at one end of the groove pit. A collection box is arranged below the other end of the groove pit. A spiral shaft is arranged in the groove pit and is provided with a spiral vane. One end of the spiral shaft is connected with the first motor through a universal coupling. The other end of the spiral shaft is a free end and suspends above the collection box. The end, close to the collection box, of the groove pit is downwards inclined. The inclination angle of the groove pit is smaller than or equal to 5 degrees. One end of the spiral shaft is connected with the first motor through the universal coupling, the other end of the spiral shaft is the free end, the spiral shaft is attached to the steel plate at the bottom of the groove pit through dead weight, winding of long iron chips is prevented, thus chip removal is smooth, automatic chip removal is achieved through the whole spiral chip removal device, labor intensity is relieved substantially, and efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of lathe processing, in particular to a spiral chip removal device and a chip removal method for a lathe. Background technique [0002] Lathes such as C61200 heavy-duty lathes produce small and long iron filings during processing. The existing spiral chip removal device is mainly for small particle iron filings. If it is used for long iron filings, long iron filings usually appear. The entanglement of chips will affect the efficiency of chip removal. When the amount of iron chips is large or the iron chips are entangled, it will cause greater resistance to the screw conveyor rod, which will easily cause the screw conveyor rod to jump in the screw chip removal device, which will cause greater damage to the motor. damage. [0003] CN105058156A discloses a spiral chip removal machine for machine tools, which consists of a geared motor, a universal joint, a rotating shaft, a spiral blade, a chip guide groove an...
