A vibration damping device for use in a work glove includes a planar plastic body having palm, thumb and finger areas, and a plurality of resilient, compressible projections extending outwardly from at least one surface of the body. Planar areas or webs in the knuckle and finger joint areas of the body make the device flexible for easy grasping of a tool and bunching of projections in such areas. Bunching of the projections is also avoided or reduced by arranging the projections in parallel, arcuate rows extending from the thumb side rearwardly toward the wrist end of the body.

The invention discloses an improved inner-pushing type clamping device for a numerical control tube bending machine and belongs to the field of numerical control tube bending machines. The improved inner-pushing type clamping device solves the problems that an oil cylinder of an existing clamping device for a numerical control tube bending machine is poor in rotation sealing in the autorotation process and is likely to leak oil, and the service life is short. The improved inner-pushing type clamping device comprises a flexible chuck, an oil cylinder and a component, wherein the flexible chuck and the oil cylinder are connected through the component. The component for connecting the flexible chuck and the oil cylinder comprises a chuck pushing bush and a rotating rod. The oil cylinder comprises a cylinder body and a piston rod arranged in the cylinder body, and the chuck pushing bush is arranged at the stretching-out end of the piston rod, is fixed relative to the piston rod in the axial direction and can relatively rotate around the axis. The rotating rod is arranged in the piston rod, and is connected with the chuck pushing bush in the connecting mode that the rotating rod and the chuck pushing bush can rotate synchronous and move relatively in the axial direction. The flexible chuck is arranged at one end of the rotating rod. By means of the improved inner-pushing type clamping device, the problem of oil leakage caused by poor rotation sealing of the oil cylinder can be solved, so that the working stability of the clamping device is improved, and the service life is prolonged.

The invention discloses a double-twist machine winding displacement guide rod pair parameter configuration method. The method comprises the following steps that 1) according to the diameter d of a winding wire rod, a guide rod and a matched guider thereof are selected; 2) the total lead S of the guide rod is calculated; 3) the thread pitch p is calculated; 4) the guide rod large diameter d, guiderod intermediate diameter d2, guide rod small diameter d1 and thread width U are determined; 5) the lead angle psi is calculated; 6) the positive pressure F and strength P of the guider are calculated; 7) the row spacing h of the winding wire rod is calculated; 8) the reversing radius R1 of the guider and the reversing radius R2 of the guide rod are calculated; 9) three-dimensional modeling is performed according to the various determined dimension parameters of the guide rod and matched guider, and all the dimension parameters of the guide rod and matched guider are finally corrected according to three-dimensional verification results until the guide rod and the guider run flexibly without sticking. The winding displacement guide rod pair configured by the method has reasonable parameters, the wire rod winded by the designed winding displacement guide rod pair is uniform and orderly, no wire disorder or reel swelling exists after layer-by-layer winding and full winding, and the qualified rate of the twisted wire rod is greatly increased.

The invention discloses a rotary table driving device for a bottle making machine. The rotary table driving device comprises a part A rotary table driving device arranged on a bedplate, and / or a part B rotary table driving device arranged on the bedplate.
