Problems solved by technology

[0004] The shortcomings of the existing technology are that on the one hand, it is necessary to use a hydraulic linkage to hold the positioning device to position the cylinder block, which increases the complexity of the fixture and the manufacturing cost. On the other hand, the use of the fixture is limited, such as when the machine tool is not equipped with a gas-liquid interface device. , it is necessary to connect a gas-hydraulic station outside the machine tool, which greatly affects the operability and convenience

Abstract

The invention discloses an air cylinder clamp. The air cylinder clamp comprises a base, spindle hole semicircular location blocks, clamping units and a cylinder hole slider linkage opening unit. Location end surface matched with to-be-located air cylinder front and rear stop spindle semicircular holes are arranged on the spindle hole semicircular location blocks. The clamping units are arranged on base location bosses on the inner sides of the spindle hole semicircular location blocks and comprise clamping supports, T-shaped screw pairs and clamping pressing blocks. A middle block bearing stop location block is provided with air cylinder bearing block location sides. The cylinder hole slider linkage opening unit comprises a base column and a cylinder hole slider component arranged at the top end of the base column. The air cylinder clamps clamp the air cylinder from the end and the sides, the measurement probe spot measurement function of a machining center spindle is used for finding reference coordinate values of machining of air cylinder process location pin holes, and accordingly, accurate machining of air cylinder process location pin holes is achieved, and the air cylinder hole wall thickness uniformity is guaranteed finally.

Description

technical field [0001] The invention relates to the field of positioning tooling, in particular to a clamp for a cylinder block. Background technique [0002] Such as figure 1 and figure 2 As shown in the figure, the cylinder block of the dry cylinder liner of the diesel engine, because the coolant does not directly contact the cylinder liner, in order to ensure the cooling effect of the diesel engine cooling system, the uniformity control of the wall thickness of each cylinder hole is highly required (wall thickness a=b). Due to the existence of casting errors, there will be deviations in the wall thickness of the blank cylinder bore of each cylinder block. The uniformity of the wall thickness among the cylinder bores must be guaranteed by machining, and the position accuracy of the process positioning reference of the cylinder block is directly determined. The position accuracy of the cylinder bore is determined, which directly determines the final wall thickness of the...
