By means of the cooling device for the machine tool, effective active cooling on the speed change mechanism and the operating mechanism can be performed; temperatures of the speed change mechanism and the operating mechanism, and temperature of lubricating grease of the speed change mechanism or the operating mechanism can be prevented from being too high; and increasing abrasion of a transmission mechanism and machine failure can be avoided.
Description
Technical field
The utility model belongs to motor and gear, operating mechanism's forced air inlet cooling device of electric tool, garden instrument and similar means machine.
Background technology
On toolroom machine, only motor is cooled off at present.There is not special cooling for gear and operating mechanism.In use; When understanding because of work such as gear and operating mechanisms; Producing high temperature can't cool off, and makes that the toolroom machine temperature raises, motor load strengthens, ability to work descends, continuous working period shortens, even causes machine gear or operating mechanism's lubricant grease temperature too high; Transmission mechanism wearing and tearing aggravation, machine failure etc.Also can cause machine surface temperature and motor temperature of outgoing air too high, cause the user to grip uncomfortable even situation such as scald.Such problem not only lets the user feel to bother very much, has also increased the return of goods risk that therefore manufacturing enterprise produces.
The utility model content
The purpose of the utility model is to provide the cooling device that uses on a kind of toolroom machine
The technical solution that realizes the utility model purpose is: a kind of cooling device of toolroom machine; Comprise casing, motor, fan, motor is fixed in the casing, and fan is fixed on the output shaft of motor; Be provided with the motor cooling air inlet in casing motor stiff end one side; On casing, be provided with motor cooling air outlet around the fan, on casing, be provided with gear or operating mechanism's cooling air inlet around placement gear or the operating mechanism, gear or operating mechanism's cooling air outlet are set around the fan on casing; Division board is set on the casing; The arrangement zone of gear or operating mechanism is kept apart with fan, have air vent on the division board, settle the zone to be connected gear or operating mechanism with the low-pressure area of fan.
The utility model compared with prior art; Its remarkable advantage: initiatively cooling can be carried out effectively to gear iso-variable velocity mechanism and operating mechanism in (1); Can prevent that gear and operating mechanism's temperature are too high, the toolroom machine temperature raises, motor load strengthens, ability to work descends, continuous working period shortens and cause, even causes machine gear or operating mechanism's lubricant grease temperature too high; Transmission mechanism wearing and tearing aggravation, machine failure etc.(2) avoid causing machine surface temperature and motor temperature of outgoing air too high, cause the user to grip uncomfortable even situation such as scald.(3) have simple in structure, practical reliable, low cost and other advantages.
Below in conjunction with accompanying drawing the utility model is described in further detail.

The specific embodiment
In conjunction with Fig. 1 and Fig. 3, the cooling device of the utility model toolroom machine comprises casing 1, motor 3, fan 4; Motor 3 is fixed in the casing 1; Fan 4 is fixed on the output shaft of motor 3, and motor cooling air inlet 2, motor cooling air outlet 5, gear or operating mechanism's cooling air inlet 10, gear or operating mechanism's cooling air outlet 6 are arranged on the casing 1, are the parts of casing 1 structure; Promptly be provided with motor cooling air inlet 2 in casing 1 motor stiff end one side; On casing 1, be provided with motor cooling air outlet 5 around the fan 4, on casing 1, be provided with gear or operating mechanism's cooling air inlet 10 around placement gear or the operating mechanism, gear or operating mechanism's cooling air outlet 6 are set around the fan 4 on casing 1; 7 division boards are set on the casing 1; The arrangement of gear or operating mechanism zone 9 is kept apart with fan 4, have air vent 8 on the division board 7, settle zone 9 to be connected gear or operating mechanism with the low-pressure area 11 of fan 4.Gear or operating mechanism's cooling air outlet 6 can be set to same air outlet with motor cooling air outlet 5 or be provided with respectively.A cooling air inlet is set specially as gear or operating mechanism's cooling air inlet 10 on casing 1, or the slit through machine is as gear or operating mechanism's cooling air inlet 10.In the casing 1 wind deflector and choke plate can be set.
In conjunction with Fig. 2 and Fig. 4, the fan 4 of the cooling device of the utility model toolroom machine is that a fan or two or more combination of fans constitute.The central area of fan 4 forms low-pressure area 11 when work, form higher-pressure region 12 in the periphery.Under the effect of ambient atmos at pressure, get into low-pressure area 11 during work, the air of low-pressure area 11 is got rid of into higher-pressure region 12 under action of fan, flows to outside air by higher-pressure region 12 again.The fan of combination is that separately higher-pressure region 12 is relative, and low-pressure area 11 separately is relative.
In conjunction with Fig. 3; In the cooling device of the utility model toolroom machine; The central area of fan forms low-pressure area 11 during fan 4 work; The air of machine intimate flows to fan low-pressure area 11, and external air pressure is greater than the air pressure of machine intimate, so outside air is getting into machine intimate through the motor cooling air inlet on the casing 12 and gear or operating mechanism's cooling air inlet 10 under the effect of pressure.And flow to the air of fan low-pressure area 11; Under the effect of fan 4 rotations, got rid of into higher-pressure region 12; Higher-pressure region 12 air pressures are higher than external air pressure, and the air of higher-pressure region 12 is discharged to outside the machine through motor cooling air-out 5 and gear or operating mechanism's cooling air outlet 6.Outer cold empty of machine gets into machine and flows through around motor 3 and gear or the operating mechanism 9, heat taken away be discharged to outside the machine, forms an air cool cycles, realizes cooling to motor 3 and gear or operating mechanism 9.
