The utility model discloses a drill bit processing open blade device, the utility model relates to drill bit processing technical field. This drill bit processing open blade device includes the base, the top of base is provided with the open blade mechanism, polishes the component, sets up at the top of base, is used for polishing to the drill bit, adjusting component, including the movable frame movable mounting in the top of base, the rear side fixed mounting of movable frame has the adjusting cylinder, the inside fixed mounting of movable frame has the step motor, when the connecting block rotates with transmission frame, the limit rod is affected by radial force, the inside end gathers to transmission frame center axis, finally with the end round structure and tightly the drill bit outer circumferential surface, realizes clamping, and the screw rotation transmission has the continuity of adjustable, when the driving motor rotates different number of turns, the screw drives the transmission block to move different distance, makes transmission frame rotation angle change, and then changes the gathering degree of limit rod, to adapt to the drill bit of different diameter, to expand the scope of application.

The present application relates to the technical fields of compressor piston rod maintenance, and provides a reciprocating compressor piston rod protection device, which comprises a base, the left side of the base is connected with a bottom plate, the upper part of the bottom plate is provided with an oil tank, an oil pipe connected to the gear oil pump is output from the oil tank, an oil pipe connected to the electromagnetic reversing valve is output from the gear oil pump, an oil pipe connected to the throttle valve is output from the electromagnetic reversing valve, an oil pipe connected to the hydraulic control check valve is output from the throttle valve, an oil pipe connected to the balance valve is output from the hydraulic control check valve, and an oil pipe connected to the lifting oil cylinder is output from the balance valve. The piston rod is placed horizontally between the concave bracket and the upper and lower flaps, and the piston rod in the upper and lower flaps is converted from the horizontal state to the vertical state through the lifting action of the lifting oil cylinder, so that the deflection of the piston rod is prevented from changing, the probability of failure of the piston rod during operation is reduced, and the problem of difficult hoisting when the piston rod is vertically placed is solved.

This utility model relates to the field of machining technology, and in particular to a crankshaft lathe faceplate with a support and locking device. The faceplate body is equipped with a support device, and a ring is provided around the circumference of the faceplate body. At least one locking device is provided around the faceplate body, comprising two opposing clamping members for locking the ring. Each clamping member is equipped with a pin as a fulcrum and can swing around it. Each clamping member has a piston at its tail as a drive for its swing. The pistons of the two clamping members are arranged oppositely, with opposite pushing directions. In this embodiment of the utility model, a ring is provided at the edge of the faceplate body, and a locking device is provided around the faceplate body, comprising two clamping members that can lock the ring. Each clamping member is equipped with a piston, and the piston's pushing action can quickly lock the ring, thereby locking the faceplate. This prevents changes in the angle of force on the workpiece during crankshaft journal machining, thus ensuring crankshaft machining accuracy.

The utility model relates to the technical field of shaft structures, and discloses an aviation launcher high-stability rotating shaft structure which comprises a base, two sets of supporting plates are arranged on the upper side of the base, rotating shafts are connected to the opposite sides of the two sets of supporting plates, a first motor is installed on the upper side of the base, and the transmission end of the first motor is connected with a rotating rod. A speed reducer is arranged on the left side of the first motor, the rotating rod is connected with the input end of the speed reducer, the output end of the speed reducer is connected with the rotating shaft, and a limiting device is arranged on the left side of the first motor. And therefore, the angle change of other workpieces on the outer side of the rotating shaft is avoided, the use stability and efficiency of the device are improved, the practicability of the device is improved, and the stability and accuracy of a model airplane launching experiment are reduced.
