This utility model discloses a cable stripping device for electrical construction, relating to the field of cable stripping technology. The utility model includes a support, a base, a seat body fixedly connected to the top of the base, two fixed components fixedly connected inside the seat body, a cutting component disposed between the two fixed components, and a rotating component rotatably connected inside the seat body. The cutting component includes a rotating ring, four second mounting seats equidistantly fixed circumferentially around the outside of the rotating ring, each second mounting seat having a threaded sleeve rotatably connected inside, an adjusting screw threaded inside the threaded sleeve, a blade holder fixedly connected to the bottom of the adjusting screw, a stripping blade installed inside the blade holder, a sliding rod fixedly connected to the top of the adjusting screw, and two limiting rods fixedly connected to the outside of the second mounting seats. This utility model, by configuring stripping blades with two different cutting angles, can achieve circumferential and axial longitudinal cutting of the cable sheath, improving cutting efficiency and ensuring cutting accuracy.

The invention discloses a cooling fan machining screw locking machine with a positioning function, and relates to the technical field of screw locking machines, the cooling fan machining screw locking machine comprises a screw locking machine assembly, the screw locking machine assembly comprises a shell, a horizontal adjusting piece is fixed to the top of the shell, and a vertical adjusting piece is arranged at the movable end of the horizontal adjusting piece. Positioning, automatic shaping, multiple clamping and universal adjustable integrated operation of cooling fan machining can be achieved, the screw locking machining precision, efficiency and equipment adaptability are greatly improved, after a workpiece is placed into the tool, automatic clamping and shaping are achieved, a shaping groove is formed in the tool, subsequent workpieces can be directly and rapidly aligned, repeated calibration is not needed, and the machining efficiency is improved. And the depth of the shaping groove is flexibly adjusted, machining of cooling fans of different heights is adapted, the cooling fans are automatically clamped while the fan cover plate is fixed, it can be guaranteed that the cooling fans are centered and aligned, workpiece displacement in the screw locking process is effectively avoided, operation is easy and convenient, running is reliable, and manual positioning and clamping operation is greatly reduced.

The utility model provides assembly line visual inspection equipment, and relates to the technical field of visual inspection. A part is placed at the top end of the base, a frame body of a concave structure is fixed to the top end of the base, two second guide rods are arranged on the frame body in a sliding mode, one ends of the right sides of the two second guide rods are welded to a mounting frame, the mounting frame is of a concave structure, an air spraying pipe is rotationally arranged on the mounting frame, and the air spraying pipe is connected with an external air supply pump through a rotating connector. A second hydraulic cylinder is fixed to the right end face of the frame body, and the extending end of the second hydraulic cylinder is fixed to the mounting frame. The spraying holes are formed in the lower portion of the outer wall of the air spraying pipe in a fan-shaped array mode, and dust on parts can be cleaned more efficiently and widely during air spraying. When the mounting frame drives the air ejector pipe to move left and right, meshing transmission of the gear and the tooth row enables the air ejector pipe to rotate back and forth, the cleaning range is further expanded, and the cleaning effect is improved. And meanwhile, a second hydraulic cylinder drives a mounting frame and an air spraying pipe to reciprocate left and right, and the cleaning range of the parts is increased again.

The utility model relates to the related technical field of precision investment casting shells, in particular to a precision investment casting shell dewaxing groove which comprises a supporting frame, a lifting mechanism and a clamping mechanism, and the clamping mechanism comprises a fixing plate connected with one side of the bottom of the lifting mechanism; the two-way screw rod is rotationally connected with the fixing plate; the rotary table is connected with the center of the surface of the two-way screw rod; the internal thread ring is in threaded connection with the surface of the two-way screw rod; the driving plate is connected with the bottom of the internal thread ring; the arc-shaped plate is connected with the bottom of the driving plate; according to the utility model, the arc-shaped plate avoids the inclination possibility of the investment precision casting shell, and the bidirectional screw rod is used for simultaneously adjusting the position of the internal thread ring, so that the centering of the investment precision casting shell is ensured, and the problem of non-uniform heating caused by position deviation of the investment precision casting shell is avoided; the problems in the prior art are solved.
