Embodiment Construction
[0009] Such as figure 1 , 2 As shown, the grinding machine includes a base 1, a casing 2, a workpiece box assembly 3, a grinding head box assembly 4 and a protective cover door 5, and the workpiece box assembly 3 and the grinding head box assembly 4 are installed on the base 1 through a linear guide rail 6 arranged in a horizontal direction. Above, the linear guide rails 6 of the workpiece box assembly 3 and the grinding head box assembly 4 are arranged vertically to each other, and the workpiece box assembly 3 and the grinding head box assembly 4 are driven by a horizontal drive mechanism 7 composed of a screw nut pair to move along the linear guide rail 6. A semi-enclosed casing 2 is arranged on the base 1, and a protective cover door 5 with the same structure is arranged on the outer side of the casing 2 close to the grinding head box assembly 4 and the workpiece box assembly 3.
[0010] The upper guide column 8 is installed on the upper part of the protective cover door 5...

The invention relates to a safety protection mechanism for an inner and outer corner grinder of a piston ring. The safety protection mechanism is characterized by comprising a base, a shell, a workpiece box component, a grinding head box component and a protective cover door, wherein upper and lower guide pillar and guide sleeve structures are arranged between the protective cover door and the shell, the protective cover door is driven to close by a driving cylinder, the driving cylinder is controlled to open by a safety control box, a travel switch for controlling the driving cylinder to close is arranged on the shell or the protective cover door, a signal of the travel switch is accessed to a programmable logic controller of the grinder. The driving cylinder needs to be started by pressing buttons by both hands, so as to drive the protective cover door to close, and a safety accident caused by that an operator in a dangerous area starts the grinder mistakenly is avoided; the workpiece box component and the grinding head box component are driven to move in place by a horizontal driving mechanism while the protective cover door moves simultaneously, and the processing efficiency is improved; and after the signal of the travel switch is received by the programmable logic controller, grinding is started, and the accident that a grinding wheel is burst and splashed to hurt people caused by starting a grinding head when the protective cover door is not closed is avoided.
Description
technical field [0001] The invention relates to a piston ring inner and outer angle grinder, in particular to a piston ring inner and outer angle grinder safety protection mechanism. Background technique [0002] Piston ring is the core part inside the fuel engine and is widely used in various power machinery. It completes the sealing of fuel gas together with the cylinder, piston, cylinder wall, etc. The early piston ring was formed by casting, but with the advancement of technology , high-power steel piston rings were born, and with the continuous improvement of engine function and environmental requirements, the quality requirements for piston rings are also getting higher and higher. [0003] In the process of processing piston rings with a piston ring internal and external angle grinder, the grinding head may be used for grinding, and the grinding wheel may burst, and some operators may not enter the grinding machine according to the operating procedures during the proc...
