Be provided with stage clip (17) in described handle (16), the step surface in an end of this stage clip (17) and the handle (16) connects, and the other end of stage clip (17) is connected on the bearing (15).Stage clip plays axial location, makes between handle and the bearing to have the gap, has improved so on the one hand the flexibility that rotating shaft is rotated, on the other hand, under the effect of spring, rotating shaft can not be rotated when applying external force nobody, thereby has further improved the reliability that lapping tape substitutes wearing and tearing.
Be provided with the 3rd transition wheel (18) in the dead astern of described the second transition wheel (7), the dead astern of First Transition wheel (6) is provided with regulating wheel (19), described regulating wheel (19) is positioned at the back upper place of the 3rd transition wheel (18), and described abrasive band (4) are walked around from regulating wheel (19) and the 3rd transition wheel (18).Above structure can further increase the length in abrasive band, to improve the radiating effect in abrasive band; Regulating wheel plays the tensioning abrasive band, to prevent the abrasive band pine band occurs.
Described regulating wheel (19) is installed in the upper end of swing arm (20), the upper front lower rear-inclined setting of this swing arm (20), the lower end of swing arm (20) and riser (8) are hinged, the top of described swing arm (20) is connected with the lower end of spring (21), and the upper end of spring (21) is connected with switch.When moving switch, switch can drive spring, and the length of spring is changed, and swing arm can turn an angle around hinge like this, thereby changes the position of regulating wheel, to regulate as required the rate of tension in abrasive band.
Described riser (8) is the straight plate structure of " F " shape, and moulding is simple so on the one hand, and processing and fabricating is easy, and cost is low; Be conducive on the other hand the contact lever front end and the sponge bistrique is unsettled, for the layout of parts and the grinding of workpiece provide convenience.Side at riser (8) is installed electric cabinet (22); so that centralized arrangement electrical equipment; the opposite side of riser (8) is equipped with the guard shield (23) that shape size with it adapts; described guard shield (23) enters First Transition wheel (6), the second transition wheel (7), the 3rd transition wheel (18), regulating wheel (19), driving wheel (3), hair band wheel (12) and take-up pulley (13) cover wherein; guard shield can be protected wherein each wheel; both improve security, and can play effect attractive in appearance again.Described handle (16) stretches out outside the guard shield (23), like this more convenient operation.
Described lathe bed (1) is frame structure, and processing and fabricating is easy, and steadiness is good.
The abrasive dust that produces for the ease of drawing grinding, in lathe bed (1), be provided with sweep-up pipe (24), the lower end of this sweep-up pipe (24) is positioned at the back of lathe bed (1), the middle part of operation panel (5) is passed in the upper end of sweep-up pipe (24), and be positioned at sponge bistrique (10) under.
Be fixed with portable lamp bearing (25) at the top of described riser (8), the upper installment work lamp (26) of this portable lamp bearing (25).Portable lamp plays illumination, can make things convenient for the staff to observe and operate.
Beneficial effect: the utility model is by using sponge material as bistrique, so that the diameter of bistrique, has solved the problem of the little and difficult grinding of compressor vanelets intrados radius of curvature effectively less than 10mm; Between sponge bistrique and abrasive band lapping tape is set, lapping tape works to replace the wearing and tearing of sponge bistrique as the intermediate materials in sponge bistrique and abrasive band, has increased widely thus the service life of sponge bistrique.
