Detailed Description
As shown in fig. 1-2, a portable steel tube derusting tool comprises a main bearing, wherein a steel wire brush 3 is fixed on the inner surface of the main bearing in a circle, and an inner ring 2 of the main bearing is connected with a motor shaft of a handheld electric tool 5 through a transmission mechanism and is driven by the motor to rotate;
that is to say, when in use, the main bearing outer ring 1 does not move, but the main bearing inner ring 2 rotates, so as to drive the steel wire brush 3 to rotate and wipe off rust on the steel pipe 6. The steel pipe 6 to be derusted needs to be arranged in the main bearing in a penetrating way and closely contacted with the steel wire brush 3, and the difficulty is that any accessory for blocking the steel pipe 6 to be derusted cannot exist in the axial direction of the annular steel wire brush 3, and the annular steel wire brush 3 is required to rotate. To solve this problem, a main bearing is used as a mounting base for the wire brush 3, the inner ring of which is rotatable and the outer ring of which is fixed, enabling the mounting of equipment including a transmission.
Here, since the gear mechanism needs to be arranged offset from the axis of the main bearing, the following bevel gear 42 gear mechanism is preferred which can serve a reversing effect:
the transmission mechanism comprises a transmission rod 4, one end of which is sleeved with a bevel gear 42, the axis of the transmission rod 4 is vertical to the axis of the main bearing, and the bevel gear 42 is fixedly connected with the transmission rod 4; gear teeth meshed with the bevel gear 42 are machined on one side face of the main bearing inner ring 2, the main bearing inner ring 2 is provided with gear teeth which are sequentially marked as a transmission side, a limit bearing 41 is arranged on the side face, close to the transmission side, of the main bearing outer ring 1, and the transmission rod 4 penetrates through the bevel gear 42 at the rear end part of the limit bearing 41 to be meshed with the transmission side; the transmission rod 4 is connected with the inner ring of the limit bearing 41 in a welding mode, and the outer ring of the limit bearing 41 is connected with the main bearing outer ring 1 in a welding mode.
Of course, the transmission rod 4 can also be directly inserted between the main bearing outer ring 1 and the main bearing inner ring 2, gear teeth are machined on the periphery of the main bearing inner ring 2, and then the main bearing inner ring 2 is driven to rotate by a common gear sleeved on the transmission rod 4, so that the handheld electric tool 5 and the steel pipe 6 have certain interference.
The connection mode of the transmission rod 4 and the hand-held electric tool 5 needs to be slightly adjusted according to different types of the hand-held electric tools 5, and the two most commonly used hand-held electric tools 5 are an electric hand drill and an angle grinder.
When the hand-held power tool 5 is a hand drill for removing drill rods, the end of the drive rod 4 remote from the bevel gear 42 is inserted into a chuck of the hand drill for holding drill rods. Thus, the transmission rod 4 is inserted into a chuck of the electric hand drill to be clamped for use.
When the hand-held power tool 5 is an angle grinder without a grinding sheet, one end of the transmission rod 4 far away from the bevel gear 42 is an internal threaded sleeve which is in threaded fit with the end of a motor shaft of the angle grinder. Therefore, the internal thread sleeve is sleeved on the shaft of the angle grinder to be used.
In this embodiment, the main bearing and the limit bearing 41 are both ball bearings. The utility model discloses the special bearing that does not need to use, it can to have conventional ball bearing.
The steel pipe 6 to be derusted is in interference fit with the steel wire brush 3. Thereby allowing the rust removal of the steel pipes 6 of different outer diameters.
