The utility model discloses a driving device used for a pipe contracting apparatus comprising a motor, a first transmission mechanism and a second transmission mechanism. The first transmission mechanism comprises a large belt pulley and a first reduction gear, which are arranged coaxially. The second transmission mechanism comprises a second large reduction gear and a second reduction gear, which are arranged coaxially. The large belt pulley and a small belt pulley disposed on a motor output shaft are in a transmission connection. The second large reduction gear is engaged with the first reduction gear. A large gear is sleeved on an outer sleeve of the pipe contracting apparatus, and the second reduction gear is engaged with the large gear. In the utility model, the motor can be used to drive the outer sleeve to rotate along a central axis of a clamping assembly fixing seat, the roller can be rotated to press the pipe orifice inwardly, thereby the pipe orifice can be uniformly narrowed, the mechanization degree can be stronger, and the labor intensity of workers can be reduced.
Description
Technical field
The utility model relates to a kind of mouth of pipe manufacture field, particularly a kind of drive unit that is used for pipe reduction device.
Background technique
Pipe and outer tube added man-hour in riser and evaporating pipe all comprised, need be with outer tube sleeve outside interior pipe; And the mouth of pipe of outer tube and the tube wall of interior pipe are welded together, but generally, because many-sided factors such as needs of refrigeration coupling; The internal diameter of outer tube need cause that very big gap is arranged between the inner and outer pipes greater than the external diameter of interior pipe, has caused the inconvenience of welding; As weld badly, in use cause leak of liquid, initiation potential easily; Cause outward appearance not attractive in appearance in addition.
The spy has researched and developed a kind of pipe reduction device; Concrete visible the applicant in utility application number is: " CN201010600472.2 "; The model utility name is called the patent application prospectus of " a kind of pipe reduction device ", but this device rotate to be manual rotation, not too convenient; Labor strength is high, and mechanization degree is not high.
The model utility content
The utility model provides a kind of drive unit that pipe reduction device provides power that can be to the deficiency that exists in the above-mentioned existing technology, drives draw assembly and rotates around central shaft, thereby reduced labor strength, has improved efficient.
The technological scheme of the utility model is achieved in that
The drive unit that is used for pipe reduction device; Described drive unit comprises motor, first driving mechanism and second driving mechanism; Described first driving mechanism comprises the coaxial mounted big belt pulley and first reduction gear; Described second driving mechanism comprises the coaxial mounted second deceleration gearwheel and second reduction pinion teeth, and described big belt pulley is in transmission connection with the small belt pulley that is installed on the motor output shaft, described second deceleration gearwheel and the engagement of first reduction gear; Outer sleeve outer fixing at pipe reduction device is arranged with gearwheel, described second reduction pinion teeth and gearwheel engagement.
Adopted the beneficial effect of the utility model of technique scheme to be:
The utility model is at first clamped pipe with the clamping assembly, holds then and rotatable handle moves down to promote roller base, makes roller push against the mouth of pipe, starts motor then, makes outer sleeve along the longitudinal center's axis rotation that clamps the assembly fixed base; The rotatable handle inward that stops then again makes the roller pressed inward mouth of pipe again, and then starts motor, makes the constantly inside compressing mouth of pipe of roller rotation, thereby can dwindle the mouth of pipe uniformly; Mechanization degree is stronger, has alleviated working strength of workers.
