Problems solved by technology

The rough machining of the water plugging holes in the cylinder body is the prerequisite for the leak test of the cylinder body. In the existing production, the rough machining of the water plugging holes in the cylinder body is usually processed by a horizontal machining center or a vertical machining center, and the investment in equipment is large. It also consumes a lot of energy

Abstract

The invention discloses a fixture for conducting rough machining on water plugging holes of an engine cylinder block. An engine cylinder block to be machined is placed on a supporting plate. The engine cylinder block can conduct slippage on a base along with the supporting plate, so that feeding and discharging of a cylinder block piece are facilitated. When machining is conducted, a clamping device clamps the engine cylinder block to the supporting plate, meanwhile a locking portion locks the supporting plate and the base, it is guaranteed that in the drilling process of a drill bit is guaranteed, the cylinder block cannot waggle, and drilling deviation is avoided. A guide device plays a guide function on the drill bit of a radial drilling machine, and drilling accuracy is guaranteed.

Description

technical field [0001] The invention belongs to a jig used for cutting and manufacturing, in particular to a jig used for rough machining of water plugging holes in engine cylinder blocks. Background technique [0002] The rough machining of the engine block is mainly to process the transition datum or fine datum of the cylinder block, and to verify the quality of the casting of the cylinder block, so as to effectively avoid the flow of the cylinder block with casting defects such as air shrinkage holes and trachoma to the engine Host factory. The rough machining of the water plugging holes in the cylinder body is the prerequisite for the leak test of the cylinder body. In the existing production, the rough machining of the water plugging holes in the cylinder body is usually processed by a horizontal machining center or a vertical machining center, and the investment in equipment is large. At the same time, the energy consumption is also quite large. Therefore, it is part...
