Abstract
The utility model relates to an electric engineering drilling machine with a drilling machine shaft which is uneasy to be abraded. A shaft protective sleeve is fixedly sleeved on the drilling machine shaft of the electric engineering drilling machine and a limber hole is communicated with a transverse cooling water way of the front segment of the drilling machine shaft. Oil seals at two sides of the limber hole and the transverse cooling water way contact with the shaft protective sleeve to generate the friction, thus avoiding the oil from directly abrading the drilling machine shaft and extending the service life of the drilling machine shaft. The cooling water way of the electric engineering drilling machine is strictly closed, has low cost of the shaft protective sleeve, is easy to be replaced after being abraded and has good use effect.
Description
Technical field
The utility model relates to electric tool, specifically is a kind of electronic engineering driller.
Background technology
In engineering construction, the application of electronic engineering driller is very extensive.Be the cooling drill bit, rig axle front end has cooling water channel to communicate with water intaking valve, for preventing cooling water infiltration gear-box and motor and spattering, is equipped with oil sealing in the horizontal cooling water channel both sides of rig axle outward.But because the water infiltration lubricating oil is to the unlubricated effect of contact-making surface between oil sealing and the rig axle, the rig axle in a short time promptly can be by oil sealing heavy wear, and to making cooling water channel poorly sealed, cooling water infiltration gearbox etc. make the rig cisco unity malfunction.Need operations such as built-up welding, turning, quenching and repair the rig axle, time-consuming, cost is quite high.Higher as more renewing rig axle cost.
Summary of the invention
The utility model is exactly that service life is short for the rig axle that solves existing electronic engineering driller is is easily worn and torn by water seal, the defective that maintenance cost is high and a kind of electronic engineering driller that designs.
The rig beam warp gearbox of the electronic engineering driller of the utility model links to each other with motor; horizontal cooling water channel and vertical cooling water channel are arranged in the rig axle leading portion; the rig axle is fixing suit protective shaft jacket tube outward; there is the limbers to communicate on the protective shaft jacket tube with horizontal cooling water channel on the rig axle; there is oil sealing both sides, limbers on the protective shaft jacket tube; the spacer ferrule that the band limbers is arranged between the oil sealing, protective shaft jacket tube can pin or screw fixedly connected with the rig axle.The protective shaft jacket tube is interior, the horizontal cooling water channel of rig axle both sides also can block water seal, as the O RunddichtringO.
The utility model has the cooling water channel of electronic engineering driller of protective shaft jacket tube tight-closed; because the friction that becomes between rig axle surface and the water seal is the friction between protective shaft jacket tube and the oil sealing; avoided rig axle surface to be worn and torn by oil sealing; thereby prolonged the working life of rig axle, reduced use cost.Adopt protective shaft jacket tube cost low, the back that is worn is changed also very convenient.
Description of drawings
Fig. 1 has the electronic engineering driller structural representation of protective shaft jacket tube for the utility model
Among the figure, 1 drill motor, 2 gearboxes, 3 rig axles, 4 oil sealings, 5 protective shaft jacket tubes, 6 spacer ferrules, 7 limbers, 8O RunddichtringO, 9 vertical water cooling roads, 10 horizontal water cooling roads, 11 limbers, 12 cooling water valves, 13 felt collar oil sealings, 14 spring flanges, 15 screws.
The specific embodiment
Figure 1 shows that the utility model preferred embodiment, shown in the rig axle 3 of electronic engineering driller link to each other with drill motor 1 through gearbox 2, horizontal cooling water channel 10 and vertical cooling water channel 9 are arranged in rig axle 3 leading portions.On the rig axle 3, with the fixing suit protective shaft jacket tube 5 of screw 15, have limbers 11 to communicate with horizontal cooling water channel 10 on the rig axle 3 on the protective shaft jacket tube 5, there is oil sealing 4 11 both sides, limbers on the protective shaft jacket tube 5, and the spacer ferrule 6 of band limbers 7 is arranged between the oil sealing 4.On the rig axle 3 in the protective shaft jacket tube 5, the horizontal cooling water channel 10 both sides seal O RunddichtringO 8 that blocks water, rig axle 3 bearings have the felt collar oil sealing 14 of band spring flange 15 outward.Laterally cooling water channel 10 7,11 communicates with cooling water valve 12 through the limbers.
Claims (2)
1, a kind of electronic engineering driller; rig beam warp gearbox links to each other with motor; horizontal cooling water channel and vertical cooling water channel are arranged in the rig axle leading portion; there is oil sealing horizontal cooling water channel both sides on the rig axle; laterally cooling water channel communicates with water intaking valve; it is characterized in that the last fixedly suit protective shaft jacket tube (5) of said rig axle (3); protective shaft jacket tube (5); on have limbers (11) to communicate with horizontal cooling water channel (10) on the rig axle (3), there is oil sealing (4) both sides, limbers (11) on the protective shaft jacket tube (5).
2, electronic engineering driller according to claim 1 is characterized in that rig axle (3) in the said protective shaft jacket tube (5) goes up horizontal cooling water channel (10) the both sides seal (8) that blocks water.
