Electric drill equipment capable of automatically adjusting speed according to hardness

Abstract

The invention discloses electric drill equipment capable of automatically adjusting the speed according to the hardness. The electric drill equipment comprises a moving box, a reciprocating pushing cavity with an upward opening and a rightward opening is formed in the moving box, a clamping box is slidably connected to the lower wall of the reciprocating pushing cavity left and right, and a hinged plate located on the left side of the clamping box is slidably connected to the lower wall of the reciprocating pushing cavity left and right; and the lower wall of the reciprocating pushing cavity is rotationally connected with a crankshaft located on the left side of the hinged plate, a spring block is fixedly connected to the right end face of the hinged plate, a spring cavity is formed in the spring block, the right wall of the spring cavity communicates with a sliding cavity with a rightward opening, a clamping cavity with an upward opening is formed in the clamping box, and the left wall and the right wall of the clamping cavity are rotatably connected with a two-way screw. According to the electric drill equipment capable of automatically adjusting the speed according to the hardness, a drill bit can be driven to perform left-right reciprocating motion while being fed towards one side at a constant speed, so that the drill bit is prevented from being clamped, and meanwhile, the movement of a push block is controlled through the compression state of a spring.

Description

technical field [0001] The invention relates to the related fields of electric drills, in particular to an electric drill equipment with automatic speed regulation according to hardness. Background technique [0002] An electric drill is a drilling tool that uses electricity as power. It is the most demanded electric tool product. When using an electric drill, it often encounters the problem that the object is hard and difficult to drill. At this time, it is usually necessary to adjust the speed of the drill bit. This often It is necessary to pause the drilling work to adjust, and when the hardness of the object is difficult to determine, it needs to be adjusted repeatedly, which greatly wastes time. Some existing belt-driven electric drilling equipment is difficult to drive more stably. And it generally does not have the function of anti-jamming. The electric drill equipment with automatic speed regulation according to the hardness explained in the present invention can sol...
