Abstract
The utility model discloses a maintenance-free wedge-shaped clamping mechanism of a full-rotation drilling machine, which comprises an inclined slide plate arranged at the inner side of a gear ring at the outer side of a sleeve of the full-rotation drilling machine; the straight sliding plate is arranged on the outer side of the casing of the full-slewing drilling machine; a wedge-shaped slideway is formed between the oblique sliding plate and the straight sliding plate, and a wedge-shaped fixture block with the upper end connected with the movable connecting rod is arranged in the wedge-shaped slideway; the motion surface of the wedge-shaped fixture block is provided with a wear-resistant alloy plate embedded with a plurality of columnar graphite points. By adopting the structure, the wear-resistant alloy plate inlaid with a plurality of columnar graphite points is arranged on the motion surface of the wedge-shaped clamping block (namely the butt joint surface of the wedge-shaped clamping block, the oblique sliding plate and the straight sliding plate), and the columnar graphite points can play a good lubricating role, so that the motion is smooth and the friction resistance is reduced even if lubricating oil is not injected into the motion surface frequently. The drilling machine effectively avoids the occurrence of corrosion, deadlocking and unsmooth movement, reduces the maintenance intensity and time, improves the working efficiency of the drilling machine and reduces the use cost.
Description
Technical Field
The utility model belongs to the technical field of the complete rotary drill machine accessory, a full rotary drill machine non-maintaining wedge clamping mechanism is related to.
Background
At present, the main clamping device of the full-rotary drill generally adopts a wedge-shaped clamping mechanism, the technical core of the main clamping device requires that a wedge-shaped clamping block can smoothly move up and down in a wedge-shaped slideway, but because the working environment of the clamping mechanism is severe, corrosion, blockage and unsmooth movement often occur, so that the working efficiency of the drill is reduced, and the use cost is increased.
Disclosure of Invention
The utility model aims at providing a simple structure, reasonable in design can effectively overcome the full rotary drill non-maintaining wedge clamping mechanism of current full rotary drill owner clamping device weak point.
The utility model adopts the technical proposal that: the mechanism comprises an inclined sliding plate which is arranged on the inner side of a gear ring on the outer side of a sleeve of the full-slewing drilling machine; the straight sliding plate is arranged on the outer side of the casing of the full-slewing drilling machine; a wedge-shaped slideway is formed between the oblique sliding plate and the straight sliding plate, and a wedge-shaped fixture block with the upper end connected with the movable connecting rod is arranged in the wedge-shaped slideway; the method is characterized in that: the motion surface of the wedge-shaped fixture block is provided with a wear-resistant alloy plate embedded with a plurality of columnar graphite points.
By adopting the structure, the wear-resistant alloy plate inlaid with a plurality of columnar graphite points is arranged on the motion surface of the wedge-shaped clamping block (namely the butt joint surface of the wedge-shaped clamping block, the oblique sliding plate and the straight sliding plate), and the columnar graphite points can play a good lubricating role, so that the motion is smooth and the friction resistance is reduced even if lubricating oil is not injected into the motion surface frequently. The drilling machine effectively avoids the occurrence of corrosion, deadlocking and unsmooth movement, reduces the maintenance intensity and time, improves the working efficiency of the drilling machine and reduces the use cost.
Drawings
FIG. 1 is a schematic view of the present invention;
fig. 2 is a schematic structural diagram of the wear-resistant alloy plate of the present invention.
Detailed Description
As shown in the figure, the utility model discloses an install the inboard slide 8 that appears to one side of ring gear 1 in the full rotary drill sleeve pipe 10 outside. And the straight sliding plate 7 is arranged on the outer side of the casing 10 of the full slewing drilling machine. A wedge-shaped slideway 9 is formed between the oblique sliding plate 8 and the straight sliding plate 7, and a wedge-shaped clamping block 2 with the upper end connected with the movable connecting rod 5 is arranged in the wedge-shaped slideway 9. The motion surface of the wedge-shaped fixture block 2 (namely the butt joint surface of the wedge-shaped fixture block 2, the oblique sliding plate 8 and the straight sliding plate 9) is provided with a wear-resistant alloy plate 3 embedded with a plurality of columnar graphite points 6. The wear-resistant alloy plate 3 is installed on the wedge-shaped fixture block 2 through a bolt 11.
The utility model discloses a working process does: the oil cylinder 4 supplies oil, the piston of the oil cylinder moves up and down, the wedge-shaped fixture block 2 is driven by the movable connecting rod 5 to move up and down in the wedge-shaped slideway 9, the radial position of the wedge-shaped fixture block 2 is changed, the drill sleeve 10 is clamped, the clamping force of a drill is transmitted to the drill sleeve 10, and the drill sleeve 10 rotates in the circumferential direction and moves up and down.
