Abstract
The utility model discloses an automatic indexing means of roots fan wheel processing belongs to roots fan processing equipment technical field, which comprises a frame one side is equipped with the base, and the opposite side is equipped with the graduated disk, and positioning core axle one end is run through the graduated disk and is fixed on the base fixed connection fastening external member on the positioning core axle be equipped with scalable bracing piece in the fastening external member, scalable bracing piece passes through the bracket connection roller, through locating the scalable bracing piece that faces the central point of roller axis and put on the fastening external member, increases scalable bracing piece to fan wheel's support intensity, through adjusting scalable bracing piece height, pushes up tight fan wheel constantly, guarantees that fan wheel keeps the position unchangeable when rotatory, improves and mills the precision, this indexing means simple structure, convenient to use, and the location is accurate.
Description
Technical Field
The utility model belongs to the technical field of roots's fan processing equipment, especially, automatic indexing means of roots's fan impeller processing.
Background
The Roots blower is a positive displacement blower, and has two three-blade impellers rotating relatively in the sealed space between casing and wall board to compress and convey gas. No matter where the two impellers rotate, a certain minimum clearance can be kept, thereby ensuring that the leakage of the gas is within the allowable range,
at present, when a Roots blower impeller is machined, after a curved surface line is machined, the to-be-machined rotor needs to rotate by a certain angle, then another curved surface line is machined continuously, the indexing auxiliary device becomes necessary equipment, and a workpiece is clamped on a chuck to be rotated, indexed and positioned. However, the conventional indexing aid can only clamp one end of the rotor by abutting against two ends of the rotor, so that the rotor is inclined due to unbalanced stress during rotation.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defect that the rotation adds holds unstability among the prior art, the utility model provides an automatic indexing means of roots fan impeller processing.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides an automatic indexing means of roots's fan wheel processing which characterized in that: the positioning device comprises a frame, wherein a base is arranged on one side of the frame, an index plate is arranged on the other side of the frame, one end of a positioning mandrel penetrates through the index plate and is fixed on the base, a fastening external member is fixedly connected to the positioning mandrel, a telescopic supporting rod is arranged in the fastening external member, and the telescopic supporting rod is connected with a roller shaft through a bracket.
Preferably, the base and the index plate are rotatably connected with the frame through a rotating bearing.
Preferably, the index plate is provided with a positioning hole, and the rack is provided with an insertion hole matched with the positioning bolt.
Preferably, the telescopic supporting rods are uniformly distributed in the fastening sleeve at equal intervals along the circumference.
Preferably, the telescopic supporting rod is opposite to the central position of the axis of the roll shaft.
Compared with the prior art, the utility model discloses the beneficial effect who has:
the supporting strength of the fan impeller by the telescopic supporting rod is increased by the telescopic supporting rod arranged on the fastening sleeve part and opposite to the central position of the axis of the roller shaft;
the fan impeller is constantly pressed tightly by adjusting the height of the telescopic supporting rod, so that the fan impeller is kept unchanged in position during rotation, and the milling precision is improved;
the indexing device has the advantages of simple structure, convenient use and accurate positioning.
