Problems solved by technology

[0003] Precision castings need to be polished after casting to remove the burrs on the outer wall. The existing grinding device will shake during the grinding process, resulting in a decrease in precision castings, and the metal particles produced by grinding are difficult to collect. For this reason, the present invention proposes a grinding device for precision castings and its positioning and clamping mechanism that can solve the above problems

Abstract

The invention discloses a positioning and clamping mechanism. The positioning and clamping mechanism comprises a workbench, a fixing frame, first lining rods and second lining rods; two sets of first sliding rails are arranged at the upper end of the workbench at intervals; each set of first sliding rails is slidably connected to two sets of movable blocks, telescopic columns are arranged at the upper ends of the movable blocks, and the upper ends of the telescopic columns are connected to a bearing plate; the fixing frame is arranged at the upper end of the workbench, a movable plate is movably arranged in the middle of the fixing frame, and racks are arranged on the two sides of the movable plate; the two sets of first lining rods are symmetrically arranged on the front side of the fixing frame with respect to the central axis of the movable plate as the symmetry axis; the two sets of second lining rods are symmetrically arranged on the front side of the fixing frame with respect to the central axis of the movable plate as the symmetry axis and are positioned on the outer sides of the first lining rods; and the movable plate moves forwards along the fixing frame, a rack is meshed with a transmission gear and the transmission gear is meshed with a gear ring, the two sets of clamping arms are driven to rotate at the positions close to each other, the two sides of the precision casting abut against each other, and the movable plate abuts against the rear side of the precision casting. Meanwhile, a polishing device for the precision casting is also provided.

Description

technical field [0001] The invention relates to the technical field of precision casting production, in particular to a grinding device for precision castings and a positioning and clamping mechanism thereof. Background technique [0002] Precision casting refers to the general term for the process of obtaining precise size castings. It is a metal forming object obtained by various casting methods. Compared with the traditional sand casting process, the size of the casting obtained by precision casting is more accurate and the surface finish is better. It mainly includes : Investment casting, ceramic casting, metal casting, pressure casting, lost foam casting. [0003] Precision castings need to be ground and polished after casting to remove the burrs on the outer wall. The existing grinding device will shake during the grinding process, which will reduce the precision of precision castings, and the metal particles generated by grinding are difficult to collect. For this re...
