Detailed description of the invention
See Fig. 1 ~ 6, a kind of grinding descaling machine compensation mechanism that the present invention relates to, described compensation mechanism includes housing 1, manual override mechanism 2 and compensation hydraulic mechanism 3 are installed in described housing 1, manual compensation can be carried out respectively regulate and compensation hydraulic adjustment, described manual override mechanism 2 includes the worm gear structure be installed in housing 1, and the worm screw 2.1 in worm gear structure stretches on one end of being placed in outside housing 1 and is set with a regulating handle 2.3, for manual, worm screw 2.1 is regulated, worm gear 2.2 central coaxial in described worm gear structure revolves and is equipped with a screw mandrel 2.4, this screw mandrel 2.4 one end is connected with grinding mechanism, compensate for the emery wheel promoted on grinding mechanism, the other end is set with a cover cylinder 2.5(and can plays dust-proof effect of Denging), described screw mandrel 2.4 and worm gear 2.2 form one and are similar to the screw mechanism that feed screw nut coordinates, for the rotary motion of worm gear 2.2 being converted to the rectilinear motion of screw mandrel 2.4, and the outer wall of screw mandrel 2.4 is provided with a flat key groove 2.6 along its axis direction, this flat key groove 2.6 forms a flat key structure (concretely with housing 1, on the shell wall of housing 1, cross-under has bolt to insert above-mentioned flat key groove 2.6 to form a flat key structure), thus screw mandrel 2.4 can only be moved linearly under the operation of this flat key structure, the hydraulic jack 3.1 of described compensation hydraulic mechanism 3 is fixed on housing 1, and the piston rod of hydraulic jack 3.1 is rack piston bar 3.2, the ratchet 3.3 of described compensation hydraulic mechanism 3 is set on worm screw 2.1, described worm screw 2.1 is also set with gear 3.5, and gear 3.5 is meshed with the tooth bar on rack piston bar 3.2, the ratchet 3.4 forming ratchet and pawl arrangement with ratchet 3.3 is installed on gear 3.5,
The principle of above-mentioned compensation mechanism is:
One, manual compensation, worm screw 2.1 is driven to rotate by regulating handle 2.3, worm gear 2.2 is driven to move in a circle, thus make to carry out rectilinear motion with the screw mandrel 2.4 of worm gear 2.2 threaded engagement, meanwhile, under the cooperation of flat key effect, this screw mandrel 2.4 can only carry out rectilinear motion, thus the grinding mechanism promoting to be connected with screw mandrel 2.4 moves, on grinding mechanism emery wheel can mobile carry compensate;
Two, compensation hydraulic, primer fluid compressing cylinder 3.1, namely rack piston bar 3.2 promotes ratchet 3.3 by gear 3.5 and ratchet 3.4 and rotates, simultaneously due to the existence of ratchet 3.4, when closedown hydraulic jack 3.1 also there will not be the phenomenon fallen back, ensure that the precision of Compensation Regulation; The ratchet 3.3 rotated can drive worm screw 2.1 to rotate, and operating principle is afterwards the same with manual compensation.
Above-mentioned detailed description of the invention is only an optimization scheme, and those skilled in the art conceive the variation and improvement done according to the present invention, all within the protection domain of this patent.
