The invention relates to a clamp, in particular to a clamping device which is applicable for a rotation body with external surfaces of rotating body and used for screwing threads; the clamping device comprises a cylinder, a first connecting rod, a second connecting rod, an upper clamping block and a lower clamping block; the cylinder is arranged on a cylinder supporter; one end of the cylinder connecting rod is connected with the output end of the cylinder and the other end thereof is respectively connected with one end of the first connecting rod and the second connecting rod by a pin shaft; the lower clamping block is connected with the other end of the first connecting rod by the pin shaft; the other end of the second connecting rod is pivotally connected on the fixed base; the cylinder is pivotally connected on the cylinder supporter; the cylinder supporter is arranged on a frame; the upper clamping block is fixed on the frame; the lower clamping block can reciprocate upwards and downwards correspondingly to the upper clamping block; the fixed base is arranged on the frame; the clamping parts of the upper clamping block and the lower clamping block are respectively provided with a concave trough; the clamping device has large clamping force, uses a connecting rod reinforcement mechanism and the driving cylinder with small diameter so as to realize large clamping force, firmly and reliably clamps the workpiece, saves the operation space and site, and has small volume, light weight and low manufacturing cost.

The invention discloses a composite injection foaming rubber midsole material and a manufacturing method thereof. The material comprises the following raw materials in parts by weight: 25-35 parts of EVA (ethylene-vinyl acetate) C1 (26-28% of VA), 5-15 parts of EVA C2 (40% of VA), 25-35 parts of OBCS, 25-35 parts of POE (polyolefin elastomer), 3-5 parts of anti-wear agent, 2-4 parts of nano calcium carbonate, 0.8-1.0 part of ZNO, 0.7-0.8 part of zinc stearate, 1-2 parts of R-103, 5-10 parts of toner, 0.4-0.5 part of stearic acid, 1.1-1.2 parts of DCP (dicumyl peroxide) and 0.8-0.85 part of AC. The material can be directly used in an EVA injection technique.

The invention discloses a robot finger mechanism. The robot finger mechanism comprises a motor, a lead screw, a machine base, a nut, a sleeve, an upper rod, a lower rod, an outer side rod, a flexibleforce measuring rod set and a swing finger, the flexible force measuring rod set comprises an upper shaft, a guide sleeve, a spring, an end cover, a force sensor and a lower shaft, and the flexible force measuring rod set slides in the sleeve; one end of the upper shaft and the spring are arranged in the cavity of the guide sleeve, the two ends of the upper shaft are rotationally linked with the swing finger and are slidably linked with the guide sleeve correspondingly, and the other end of the guide sleeve is fixedly connected with the end cover; the two ends of the spring abut against a large cylinder of the upper shaft and the end cover, the two ends of the force sensor are fixedly connected with the end cover and the lower shaft correspondingly, and the other end of the lower shaft isrotationally linked with the machine base; the two ends of the lower rod are correspondingly linked with the nut and the sleeve in a rotating mode, the two ends of the side rod are correspondingly androtationally linked with the machine base and the sleeve, and the two ends of the upper rod are rotationally linked with the sleeve and the swing finger correspondingly; and the motor drives the nutto slide in a machine base guide groove so that the robot finger can be bent or opened. According to the robot finger mechanism, the flexible, safe and large-load grabbing capacity is achieved while the grabbing force is sensed.
