6results about How to "Reduce inertial load" patented technology

The present invention relates to a parallel-driven three-degree-of-freedom motion platform, comprising a workbench, wherein a fixed frame is arranged on the workbench, a vertical frame is arranged on the fixed frame, a horizontal frame is arranged on the vertical frame, a rotating frame is rotatably connected to the horizontal frame, a connecting wheel group is arranged on the rotating frame, and a driving mechanism is arranged on one side of the fixed frame; a transmission wheel group is arranged on the fixed frame and the vertical frame; when the parallel-driven three-degree-of-freedom platform moves, the load is borne by four driving motors at the same time, thereby reducing the rated power of the motor to one-fourth of the original; the driving motor is installed on the outside of the motion structure, and when the motion structure is adjusted, the driving motor does not need to move with the motion structure, thereby reducing the inertial load of the motion structure, improving the stability of the motion structure, and also improving the efficiency of the motion structure adjustment.

This application provides an automated pneumatic drilling machine, comprising: a frame, horizontally placed on the ground with a base platform at the top; a sliding assembly, including a slide rail horizontally mounted on the base platform and a stamping table slidably mounted on the slide rail; a workpiece, horizontally placed on the stamping table; a pneumatic stamping assembly, suspended above the base, with a stamping plate at one end; and drill bits evenly arranged on the stamping plate. By densely arranging drill bits on the stamping plate and using the pneumatic stamping assembly to drive all drill bits to synchronously press down and drill holes, a single stamping operation can complete the hole positions that would require dozens or even hundreds of steps in traditional equipment. Compared to manual operation, it completely eliminates repetitive positioning time, significantly increasing productivity. The stamping table on the slide rail is driven by a servo motor, and the movement path is programmed and controlled by a PLC control terminal, resulting in high workpiece positioning accuracy and avoiding positional deviations during manual drilling operations.

The invention relates to the technical field of pistons, and provides a lightweight forged steel piston which comprises a piston head, a piston skirt and a piston pin seat, and is characterized in that a piston face window is formed in the piston skirt and provided with a fence type weight reduction cavity, and the fence type weight reduction cavity is located above a piston pin hole; the fence type weight reduction cavity penetrates through the piston skirt part in the direction of the piston pin hole; two sides of the piston pin hole are respectively provided with a main thrust side skirt wall and a secondary thrust side skirt wall, and the center of the piston pin hole is deviated towards the main thrust side skirt wall; the outer circle of a piston skirt part which is circumferentially connected with the piston outer pin seat and the piston face window is retracted inwards and is in smooth transition connection with the main thrust side skirt wall and the secondary thrust side skirt wall respectively; and the thickness of the main thrust side skirt wall is greater than that of the secondary thrust side skirt wall. According to the technical scheme, the weight of the piston is reduced, meanwhile, noise and vibration generated when the diesel engine works are reduced, meanwhile, the cooling effect is good, and movement of the piston in the air cylinder is more stable.

This utility model discloses a rotary engine cylinder block with a sleeve, comprising a rotary engine cylinder block and a wear-resistant cast iron cylinder liner. The rotary engine cylinder block has a circular mounting hole; the wear-resistant cast iron cylinder liner is detachably press-fitted into the mounting hole, and the wear-resistant cast iron cylinder liner has a cylinder bore with an inner surface shaped like the number "8". This utility model, through the detachable press-fit method of interference fit between the rotary engine cylinder block and the wear-resistant cast iron cylinder liner, not only ensures structural stability and prevents vibration displacement, but also enhances heat conduction through tight metal bonding, allowing heat from the cylinder liner to be quickly transferred to the cylinder block, thus comprehensively optimizing the basic performance of the cylinder block.

This utility model discloses a quadruped robot. The lower leg mechanism includes a foot pad mounting base, a support rod, and a sleeve. A first protective sleeve is fixed to the outer periphery of the support rod. The sleeve is fitted onto the first protective sleeve and slides within it, with the first protective sleeve at least covering the sliding range of the sleeve. A fixing post extending from the top of the foot pad mounting base towards its bottom is provided. The fixing post has an axially formed mounting hole, the opening of which is located at the top of the foot pad mounting base. The support rod is at least partially inserted into the mounting hole and fixedly connected to the foot pad mounting base. A reinforcing structure is provided at the top of the foot pad mounting base to enhance the strength of the edge of the mounting hole. Multiple support members are spaced apart between the fixing post and the inner wall of the foot pad mounting base. The advantages of this utility model are: enhanced strength of the entire lower leg mechanism and effective reduction of its weight, better adapting to the demands of high-speed movement.

This invention discloses a multifunctional high-toughness robot cable and its manufacturing process, relating to the field of cable technology. It includes a main power cable unit, comprising, from the inside out, a conductor assembly, an insulation layer, a shielding layer, a filling layer, an isolation layer, and a sheath layer. The conductor assembly comprises multiple graphene-reinforced silver-plated copper alloy conductor wires, each with a diameter of 0.05-0.10 mm. These conductor wires are bundled and twisted together to form a double-stranded structure, with a bundle pitch of 10-15 mm and a twist pitch of 20-30 mm, the twisting directions of which are opposite. The insulation layer is a gradient composite structure of silicone rubber and XLPE, consisting of an inner silicone rubber layer, a gradient transition layer, and an outer XLPE layer, from the inside out. The inner silicone rubber layer has a thickness of 0.3-0.5 mm, the outer XLPE layer has a thickness of 0.2-0.3 mm, and the gradient transition layer has a thickness of 0.05-0.1 mm. A functional layer is also included, positioned around the periphery of the main power cable unit, together forming the multifunctional high-toughness robot cable structure. The cable of this invention features high toughness, multifunctionality, and high market adaptability.
