The invention relates to a nursing bed, particularly to a multifunctional electric nursing bed. The multifunctional electric nursing bed comprises a bed frame, a bed board, a bed body pull-up moving mechanism, a vertical lifting convenient mechanism and a lower bed board positioning mechanism, wherein the bed board comprises a seat board, a lower bed board and a back board, the back board moves upwards and backwards during the sitting process and consistent with the movement principle of ergonomics, the pressure of the back board on the back of the human body when people sit up can be completely eliminated, the seat board is inclined downwards towards rear wheels, and the slippage of the human body is effectively prevented; the bed frame comprises an upper bed frame, a main sit frame and a lower bed frame, the upper bed frame drives the back board to sit up by virtue of the bed body pull-up moving mechanism, the lower bed frame is linked to be laid down, the movement amplitude of the gravity center of the bed body is reduced, the distance between the front wheel and the rear wheel is smaller, the lateral width of the bed body at a sit-up state is less than 0.7m, so that the multifunctional electric nursing bed is convenient for entering / exiting from an ordinary room door. The multifunctional electric nursing bed has characteristics of economical performance, practicability, stability and durability, and is not only applicable to large-sized institutions and fields such as hospitals, nursing home and the like, but also suitable for ordinary families to use.

The invention discloses an inner hole automatic chamfering device. The inner hole automatic chamfering device comprises a base plate; a fixed base is mounted on the base plate; a mold cavity base is mounted on the fixed base; the mold cavity base is connected with a rocking rod module for driving the mold cavity base to move; a mold cavity is mounted on the mold cavity base; a through hole is formed in the base plate, and is provided with a motor; a gear positioning plate is arranged above the motor; a gear set is mounted on the gear positioning plate; an output shaft of the motor penetrates through the gear positioning plate, and is connected with the gear set; the gear positioning plate is mounted on a support column module; the support column module is connected with the base plate; a detachable chamfering blade is mounted on the gear set; and the chamfering blade is positioned above the mold cavity. The inner hole automatic chamfering device is simple in operation and convenient touse, and can be suitable for machined parts with multiple inner hole diameters.

The invention relates to a self-buckled special chamfering device for a stator core, which comprises a pressing mechanism for pressing both ends of the stator core, a chamfering cutter component, a displacement driving mechanism for driving the chamfering cutter component to move close to or away from the excircle position at one end of the stator core, and a rotary driving mechanism for driving the chamfering cutter component to rotate around the excircle at one end of the stator core to chamfer the excircle at the end of the stator core. The technical scheme of the invention has the effects of improving the machining efficiency and lowering the production cost.
