when the pneumatic regulating valve with the special-shaped curved surface is clamped, the clamping part on one tooth row is firstly abutted against the surface of the valve body, for example, the clamping part on the surface of the tooth row 7, at the moment, along with the continuous movement of the gear I5, the tooth row 7 cannot move, the gear I5 rolls along the surface of the tooth row 7 which cannot move, the other tooth row 8 is driven to move towards the surface of the valve body in an accelerating way in the rolling process until the pneumatic regulating valve with the special-shaped curved surface is clamped by the other clamping part, and the tooth row 7 and the tooth row 8 are driven to move relatively in the rolling process of the gear I5, but meanwhile, the gear I5 always moves in a translation way towards the direction of the valve body, so that the force of the tooth row 7 and the tooth row 8 moving towards the direction is always kept in the relative movement process, and the two clamping parts can finally clamp the pneumatic regulating valve with the special-shaped curved surface, and the practicability of the clamp is improved;
step S3: the support frame 4 moves, the first moving block 14 is driven to move along the second sliding groove 102 through the connecting rod 401, the first two sliding blocks 18 are driven to move away from or approach to each other through the two rotating plates 17, so that the two moving plates 19 are driven to move simultaneously, the abutting plate 30 abuts against flanges on two sides of the regulating valve, the regulating valve is prevented from transversely shaking, the stability of the clamp is further improved, after the abutting plate 30 abuts against the regulating valve, the vibration detector 31 can detect valve body vibration data of the pneumatic regulating valve under the condition of different opening degrees, and whether the valve body is damaged is judged according to the data detection result;
step S4: through two movable plates 19 removal, drive two drive plates 24 and remove, the arc piece second 25 is continuous intermittent type and a plurality of arc piece first 131 butt in the drive plate 24 removal process for the drive plate 24 is following the vertical reciprocating motion of the in-process that movable plate 19 removed, and through tooth portion 26 and gear second 27's meshing relationship, drive bull stick 20 and photoelectric sensor 22 reciprocal swing, thereby carry out even detection valve body's in-process of removal running state to the regulation valve surface, reduce the dead angle that appears, can in time discover the trouble and repair, the maintenance effect has been improved.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
