Fixture for rough machining of water plugging hole in engine block
ActiveCN104959856BWon't shakeEasy loadingDrilling/boring measurement devicesWork clamping meansEngineeringCylinder block
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.

Circular arc surface drilling machining tool applied to numerical control machine tool
InactiveCN109108323AHigh precisionAdjustable distanceBoring/drilling machinesNumerical controlMachine tool
The invention discloses a circular arc surface drilling machining tool applied to a numerical control machine tool. The circular arc surface drilling machining tool comprises a supporting frame body,a placement frame, an auxiliary buckle plate, a lower pressing plate and a drilling device. A motor is fixedly connected to the bottom surface of the supporting frame body, and a rotating shaft of themotor penetrates through the bottom surface of the supporting frame body and is fixedly connected to the bottom surface of the placement frame. A plurality of partition plates are fixedly connected to the surface of the placement frame, connecting rings are fixedly connected between every two adjacent partition plates, and limiting sliding grooves are formed in the surfaces of the partition plates. Butting grooves are formed in the side walls of the partition plates, inserting-connecting holes are formed in the surfaces of the butting grooves, and the inserting-connecting holes connected withinserting-connecting rods arranged on the plate surface of the auxiliary buckle plate in an inserting mode. According to the circular arc surface drilling machining tool applied to the numerical control machine tool, circular arc plates are arranged and placed in a front-and-back aligned mode, drilling treatment of three circular arc plates when a drill bit drills at a time is realized, and the opening efficiency of the circular arc plates is greatly improved.
