A twin rotation driving apparatus is provided, including a base body, an axle unit pivotally connected to the base body for carrying a workpiece, a first driving unit disposed on the base body and having a first gear set connected to the axle unit and a first motor coaxially connected to the first gear set, and a second driving unit disposed on the base body and having a second gear set connected to the axle unit and a second motor coaxially connected to the second gear set. The twin rotation driving apparatus includes two motors and two gear sets. Therefore, smaller motors can be included in the twin rotation driving apparatus, and the twin rotation driving apparatus is compact and can still generate great enough torques.

The invention relates to polysebacic acid 1, 3-propylene glycol ester-block-polysuccinic acid butanediol block polyester, wherein the general formula is shown in the specification, the molecular weight is in a range from 10000 to 50000. The molecular weight of the polyester provided by the invention is in the range from 10000 to 50000, the thermodynamic property of the polyester is equivalent to that of PBS (Polybutylene Succinate), the degradation performance is remarkably improved, the melting point is greater than 100 DEG C, the thermal stability is better, and the processing space is wider, so that the polyester can be used in the field of high molecular materials such as food package, agricultural plastic mulching films and medical sutures, and has a wide application prospect.

The invention discloses an automatic wok which comprises a wok body, a three-oblique-blade paddle type stirrer as well as a transmission device and a power device for driving the three-oblique-blade paddle type stirrer to operate, wherein the wok body is a cylindrical pan, an enveloping surface formed by the movement of the blades in the three-oblique-blade paddle type stirrer covers the whole wok bottom, the three-oblique-blade paddle type stirrer comprises a stirring shaft, an impeller coaxially arranged on the stirring shaft and three handles circumferentially and uniformly arranged on the impeller, a blade is arranged on each handle, and the distances from the lower end surfaces of the three blades to the wok bottom are increased in turn. According to the automatic wok disclosed by the invention, the setting mode of blades on the traditional stirrer is improved so that the food heating in the wok is more uniform and the stirring efficiency of food frying is improved.

The invention relates to the technical field of machining, in particular to an irregularly-shaped hole machining device for a large machine. The irregularly-shaped hole machining device comprises a bottom frame, an installation table is welded to the bottom frame, the installation table is fixedly provided with a first guide rail through bolts, and the first guide rail is slidably provided with afirst moving base. The irregularly-shaped hole machining device has the advantages that through the cooperation of the installation table and a main installation rack, the device can provide a largermachining space, the limitations of a traditional machine tool to the size of a workpiece are broken through, therefore, irregularly-shaped holes in large machine parts can be automatically and efficiently machined instead of manual operation, and much less manpower is occupied. The device can achieve drilling, boring and milling formation of the irregularly-shaped holes through the cooperative work of a plurality of drilling devices in the main installation rack and a plurality of different cutters in the drilling devices, therefore, the irregularly-shaped holes can be directly machined and formed in a single one device, the time for repeated loading and transfer is saved, and the production efficiency is further improved.

The invention discloses a dual-rotation driving device, which comprises: a base body; a shaft unit pivotally connected to the base body to carry workpieces; a first and a second drive unit arranged on the base body; the first and second drive units Each has a motor and a gear set, each of the motors is coaxially connected with each of the gear sets, and each of the gear sets is connected with the shaft unit. Through the design of two motors and two gear sets, the present invention can generate larger torque with smaller motors and smaller volume.

The invention discloses a multi-station synchronous rear axle bearing press-fitting device. The device comprises a workbench and a rear axle die, the rear axle die comprises a plurality of bearing seats, the bearing seats are internally provided with to-be-pressed bearings, at least one side of the two axial side faces of each bearing seat is provided with a pressure applying oil cylinder, each pressure applying oil cylinder comprises an oil cylinder shell and a piston rod, pressure applying blocks attached to the side faces of the to-be-pressed bearings are arranged at the ends, facing outwards, of the piston rods, the piston rods are coaxial with the to-be-pressed bearings, the axis of each to-be-pressed bearing is parallel to the working upper plane of the workbench, a limiting assemblyand a positioning assembly for positioning the rear axle die are arranged on the workbench, and the pressure applying oil cylinders are fixed on the limiting assembly. The device has the advantages that when re-machining is carried out after pre-positioning, fixing of the rear axle die is completed by the pressure applying oil cylinders and the pressure applying blocks, the machining space is enlarged, positioning and machining are convenient, the machining precision of the to-be-pressed bearings and the bearing seats is improved, the to-be-pressed bearings are prevented from being eccentricto the bearing seats, the plurality of to-be-pressed bearings can be synchronously machined through the pressure applying oil cylinders, so that the working efficiency of bearing press-fitting is improved.
