The invention discloses a cable traction device. The cable traction device comprises a rack, a clamping mechanism, a traction mechanism, a transmission mechanism and a motor, wherein the rack is usedfor supporting and connecting all mechanisms; when traction operation is started, the clamping mechanism is started to fix a cable to a traction position and has a guiding function on cable traction;the motor is started to drive two screw rods in the traction device to rotate through a transmission device; and forward force and backward force generated by reverse rotation of the two screw rods are used for controlling traction of the cable in two directions respectively. The cable traction device is simple in structure, convenient to use and high in transmission efficiency, has certain application universality, can reduce the labor intensity and improve the construction quality, and has high practical value.

The invention relates to the technical field of robots, and provides a clamping mechanism. The clamping mechanism comprises a clamping seat and a rotating wheel, and a first clamping groove and a second clamping groove of which notches are communicated with each other are formed in the clamping seat; the rotating wheel is rotationally connected to the clamping seat around an axis, and a first clamping groove and a second clamping groove of which notches are communicated are formed in the rotating wheel; and in the rotating process of the rotating wheel, the rotating wheel has a first clamping state that the first clamping groove and the first clamping groove are matched to form a clamping space used for clamping a clamped object, and a second clamping state that the second clamping groove and the second clamping groove are matched to form a locking space used for limiting the clamped object to freely slide in the axial direction of the rotating wheel. The clamping mechanism not only can be used for clamping the clamped object, but also can switch the clamping state, so that the clamped object can freely slide in the axial direction of the clamped object and cannot fall off from the locking space; and moreover, in the switching process of the rotating wheel between the first clamping state and the second clamping state, switching can be completed without taking out the clamped object, and use is more convenient.

The invention discloses a main transmission mechanism of an all-electric servo numerical control turret punch press. The main transmission mechanism comprises a servo motor, a crankshaft, a connection rod, a sliding block, a frame and a fixing frame. The crankshaft is connected with the sliding block. The input end of the crankshaft penetrates through the frame and is fixedly connected with a motor rotor in a rigid mode. The motor rotor and a motor stator are hinged through a front bearing and a rear bearing. The motor stator is coaxially sleeved with the fixing frame, and at least one elastic assembly is arranged between the motor stator and the fixing frame. Each elastic assembly comprises multiple suspension components, first torsion components and second torsion components, wherein the first torsion components and the second torsion components are distributed in symmetry. By means of the structure, the servo motor is flexibly connected with the frame, the axial size is compact, and the load inertia of the mechanism is small. Radial deformation in any direction can happen and is not large in rigidity. When the radial deformation in any direction happens, the suspension components have an energy consumption effect. Torsion deformation around the axial direction is avoided, torsion rigidity is infinite, and the main transmission mechanism can be applied to occasions of high speed and heavy loads.
