2results about How to "Offset torque" patented technology

The utility model relates to a kind of shock absorption technology technical field, concretely relates to a kind of vibrating screen rubber shock absorbing spring. Including by a plurality of compression unit series into one's body shock absorber, shock absorber upper end is fixed with upper sleeve, upper sleeve upper portion is internally machined with internal thread, upper sleeve lower end is internally machined with four edge hole, shock absorber lower end is fixed with lower sleeve, lower sleeve is slidably provided with connecting rod, connecting rod penetrates lower sleeve, connecting rod upper end is fixed with four edge head, four edge head can be connected in four edge hole after going up, connecting rod lower end is machined with four edge block. By the four edge head of connecting rod top and the clamping design of the four edge hole of upper sleeve, rigid fixation of upper sleeve is realized in bolt tightening process. This structure can effectively offset the torque generated when bolt rotates, avoid the deformation or damage of rubber shock absorbing spring due to stress distortion, while ensuring axial centering during threaded connection, greatly improve installation efficiency.

The utility model relates to the field of welding alternate platform discloses a double position alternate platform of large -scale casting automatic welding house, including bearing frame, bearing frame rotatable setting in the upper of mounting base, the inner wall fixed with drive motor of mounting base, the output shaft one end of drive motor is fixed with the bottom surface of bearing frame, both ends of bearing frame all are fixed with the placing table, the left and right sides of placing table all are fixed with the pneumatic cylinder, the telescopic link one end of pneumatic cylinder extends to the placing table, the telescopic link one end of pneumatic cylinder is fixed with the clamping plate, two clamping plates between the setting have two fixed plates. In the utility model, through the cooperation of pneumatic cylinder, clamping plate, fixed plate, sleeve and connecting plate, the casting of different models can be clamped and fixed in multiple directions, the casting is kept in the center position of placing table, the accuracy of casting welding is guaranteed, and the offset of welding position in the welding vibration of casting is prevented.
