Abrasive belt grinding machine for casting head cutting and grinding assembly line of vehicle casting

Abstract

The invention relates to an abrasive belt grinding machine for a casting head cutting and grinding assembly line of a vehicle casting. The abrasive belt grinding machine comprises a mounting frame andan abrasive belt grinding mechanism, and the abrasive belt grinding mechanism comprises an abrasive belt rack, an abrasive belt main beam, an abrasive belt driving motor, a driving wheel, a driven wheel and an abrasive belt. A flexible grinding assembly is arranged between the abrasive belt main beam and the abrasive belt rack, the flexible grinding assembly comprises a flexible swing arm, bearing columns are arranged at the two ends of the flexible swing arm, the flexible swing arm is movably connected with the abrasive belt main beam and the abrasive belt rack through the bearing columns, the abrasive belt main beam is made to swing left and right in the abrasive belt rack through the flexible swing arm, a floating grinding assembly is arranged between the driven wheel and the abrasivebelt main beam, the floating grinding assembly comprises a movable support, a swing base and a floating motor, the floating motor is provided with a buffer guide wheel, an arch-shaped groove is formedin the middle of the swing base, the buffer guide wheel is arranged in the arch-shaped groove, therefore, the driven wheel swings leftwards and rightwards through the movable support, the movable support is provided with a return tension spring, and the movable support returns after grinding through the return tension spring.

Description

technical field [0001] The invention relates to the field of casting processing, in particular to an abrasive belt grinder for a casting riser cutting and grinding line for vehicles. Background technique [0002] Castings are metal shaped objects obtained by various casting methods, that is, the smelted liquid metal is poured into the pre-prepared mold by pouring, injection, suction or other casting methods, and after cooling, it is polished and other subsequent processing methods , the obtained objects have a certain shape, size and performance. Many parts of the car, such as: engine cylinder block, cylinder head, piston, flywheel housing and part of the shell, gearbox shell, chassis, etc. need to be made into castings Then assemble the car products. [0003] In the casting process, due to the needs of the process, the body of the casting has some "redundant" structural parts in addition to the shape and specifications of the workpiece itself. This part is usually called t...

Problems solved by technology

However, during the grinding process of casting products, due to the hard contact between the abrasive belt and the casting, it is very easy to produce inconsistent grinding dimensions due to insufficient grinding or excessive grinding, resulting in frequent rework of casting products after grinding
