Abstract
The utility model provides a water cooling mechanism of an engineering driller, and belongs to the technical field of electric power tools. The water cooling mechanism of the engineering driller solves the problems that serious abrasion is produced between an existing sealing ring and a main shaft, the aging failure easily happens on the sealing ring, water flows out of the head portion of a drilling machine, and the cooling effect is affected. The water cooling mechanism of the engineering driller comprises a water passing device, an output shaft axis cavity and a sealing device. The water passing device comprises a faucet and a copper elbow pipe, wherein one end of the copper elbow pipe is connected with the faucet, and the other end of the copper elbow pipe is inserted into the output shaft axis cavity from the tail end of an output shaft. The sealing device is arranged between the output shaft and the copper elbow pipe. On one hand, the sealing device plays a role of sealing, and on the other hand, the sealing device plays a role of supporting the copper elbow pipe. Compared with a traditional rhinestone engineering driller, the water cooling mechanism of the engineering driller has the advantages that improvement is made on the water inflowing manner, the cooling water directly enters from the tail end of the output shaft and is sprayed out from the front end of the output shaft through the water pressure, the pressure subjected by a sealing ring is small, the abrasion of the sealing ring is improved, and the sealing effect is good.
Description
Technical field
The utility model belongs to the electric tool technical field, relates to a kind of engineering driller, particularly a kind of water-cooled body of engineering driller.
Background technology
The hand-held engineering driller is a kind of boring electric tool commonly used, when operation, because the friction of drill bit and workpiece and cutting produce a large amount of heats, and cooling in time.The cooling structure of knowing altogether at present is to connect a water jacket below gearbox, the space that makes the outer formation of output shaft can hold certain water gaging, external water pipe, the water source introduced the mode with water jets under high pressure sprays in the head, compare water with traditional engineering driller and bore the temperature that can reduce drill bit, increase the wear-resisting of machinery, can come out boring the sluicings such as rock ballast that fall simultaneously, make the boring flatness more smooth, reduced spreading of dust simultaneously.
As authorize public number for disclosing a kind of hand-held engineering driller in the patent of CN2693385Y, the sealing structure for water of this utility model comprises outer hydraulic gland, sealing ring, hole back-up ring and main shaft, outer hydraulic gland is enclosed within on the main shaft, main shaft inside is hollow structure, the axle body outer ring is annular water inlet, current enter annular water inlet by the water storage cavity between outer hydraulic gland and the main shaft, and with sealing ring this water storage cavity are sealed, and prevent that current from entering gearbox inside.But because the high-speed rotation of main shaft, sealing ring can produce bigger wearing and tearing with main shaft, and the easy ageing failure of sealing ring makes water flow out from the rig head, influences cooling effect.Even more serious is that the interior hydraulic pressure of water storage cavity is bigger, and cooling water also may enter gearbox, and bearing and gear are damaged, and causes rig to be scrapped.
Summary of the invention
The purpose of this utility model is at the above-mentioned existing state of the art, and a kind of water-cooled body that does not have the engineering driller of leakage, life-span length is provided.
The purpose of this utility model can realize by following technical proposal: a kind of water-cooled body of engineering driller, comprise water flowing device, chamber, output shaft axle center and sealing device, it is characterized in that, described water flowing device comprises tap and copper bend pipe, one of copper bend pipe connects tap, the other end is inserted in the chamber, output shaft axle center from the tail end of output shaft, and sealing device is arranged between output shaft and the copper bend pipe.Sealing device can play sealing function on the one hand, can play the effect of supporting the copper bend pipe on the other hand.
In the water-cooled body of above-mentioned engineering driller, described sealing device is water seal, and hydraulic gland is on the copper bend pipe.
In the water-cooled body of above-mentioned engineering driller, described tap is connected on the head capsule of engineering driller.
In the water-cooled body of above-mentioned engineering driller, described copper bend pipe is S type structure in output shaft radial cross-section position.Above-mentioned S type structure can be walked around parts such as inner shaft, avoids the collision with some parts.
Compare with traditional water driller journey rig, this design improves water intake mode, and cooling water is directly entered from the tail end of output shaft, relies on hydraulic pressure to spray from front end, and the sealing ring pressure is less, has reduced the wearing and tearing of sealing ring, good sealing effect.

The specific embodiment
Shown in Fig. 1～3, the water-cooled body of this engineering driller comprises water flowing device, chamber 51, output shaft axle center and sealing device, the water flowing device is made up of tap 1, doubling-up 2 and copper bend pipe 3, tap 1 is arranged on the rig head capsule 4, copper bend pipe 3 one ends are communicated with tap 1, the other end is inserted in the chamber, output shaft axle center 51 from the tail end of output shaft 5, and the interface that tap 1 and copper bend pipe 3 are located in doubling-up 2 is anti-its side leakage.
Sealing device is water seal 7, and between output shaft 5 and copper bend pipe 3 and be set on the copper bend pipe 3, water seal 7 can be played sealing simultaneously and support 3 effects of copper bend pipe, and the outside of water seal 7 is established a back-up ring 6 and carried out spacing.As shown in Figure 2, copper bend pipe 3 is S type structure in output shaft 5 radial cross-section positions.
Fetch boiling water leading 1, cooling water feeds chamber, output shaft axle center 51 by copper bend pipe 3 from output shaft 5 afterbodys, after directly passing chamber, output shaft axle center 51, spray from output shaft 5 front ends, can realize refrigerating function in the time of rig work, reduce the temperature of drill bit friction, make the brill cutter be difficult for not easy fracture of rust, drill bit, the assorted bits that the current that spray when drill bit is worked also can be taken away in the hole make the work hole wall more smooth.
