The invention provides a grinding device, and belongs to the technical field of grinding equipment. A grinding assembly comprises a grinding wheel mounting frame, a grinding wheel and a motor, whereinthe grinding wheel and the motor are mounted on the grinding wheel mounting frame, the motor drives the grinding wheel to rotate, and the grinding wheel mounting frame is connected with an insertingpost on a bottom plate in an inserting mode and fixed through a locking nut; a pipe fitting clamping assembly comprises a first clamping arm, a second clamping arm, a fixing support, a bidirectional threaded rod and a guide rod; the fixing support is fixed on the bottom plate, the guide rod and the bidirectional threaded rod are arranged on the fixing support in parallel, and the bidirectional threaded rod comprises a first threaded section and a second threaded section which are opposite in threaded rotation direction; the first clamping arm is mounted on the first threaded section, and the second clamping arm is mounted on the second threaded section and simultaneously arranged on the guide rod in a sleeve mode; the first clamping arm and the second clamping arm form a clamping space fora pipe fitting to be ground, and the pipe fitting to be ground is opposite to the grinding surface of the grinding wheel. The grinding device provided by the invention can improve the grinding efficiency and grinding effect of a port of the pipe fitting.
Description
technical field [0001] The invention relates to the technical field of grinding equipment, in particular to a grinding device. Background technique [0002] In industrial production, the end faces of pipe fittings are often ground to form flat end faces or grooves to facilitate the connection between pipe fittings. [0003] In the prior art, operators often use their hands to hold one end of the pipe fitting, and the other end is in contact with the grinding wheel; the pipe fitting can be polished by turning the grinding wheel. Due to the high speed of the grinding wheel, when the pipe fittings held by the operator are grinding the ports of the pipe fittings, the ports of the pipe fittings will jump on the grinding wheel; especially when beveling the ports of the pipe fittings, the pipe fittings need to be set at an inclination relative to the grinding wheel. The operator has high requirements for the stability of the pipe fittings. [0004] Therefore, when the operator ho...
