Description

Technical Field

[0001] This utility model relates to the field of cylinder bore machining technology, and in particular to a tooling for positioning and machining cylinder bearing holes. Background Technology

[0002] Cylinder bore positioning machining refers to the process of ensuring that the position and orientation of the cylinder are correctly aligned with other components when the cylinder is installed on the engine, and performing precise machining. It is widely used in the field of automobile engine manufacturing, such as the machining of crankcase cylinder bores. When fixing the cylinder with conventional tooling, it is inconvenient to machine the cylinder fixed on the base plate, thus affecting the use effect of the tooling.

[0003] The prior art CN220807018U discloses a tooling for locating and machining cylinder bearing holes, including a diamond pin, a locating shaft, a locating seat, a base plate, a pressure head, a hydraulic cylinder, and a hydraulic cylinder base. The diamond pin and locating shaft are assembled onto the locating seat, which is then fixed to the base plate. The locating shaft is installed, and the pressure head is connected to the hydraulic cylinder. The hydraulic cylinder and its base are then fixed together to the base plate. The hydraulic cylinder is released, and the cylinder spark plug orifice is aligned with the cylinder. The cylinder bore is inserted along the guide head of the locating shaft. The diamond pin is inserted into the M6 ​​threaded hole on the cylinder flange. The cylinder is inserted until the flange surface is in complete contact with the locating plane of the locating seat. The clamping hydraulic cylinder drives the pressure head to fix the cylinder to the base plate, thereby improving the tooling's effectiveness.

[0004] In normal use, the diamond pin and positioning shaft are assembled onto the positioning seat, and the positioning seat is fixed to the base plate. Due to the different specifications and dimensions of the cylinders, the positioning shaft is installed. In the existing technology, when processing cylinders of different specifications and dimensions, it is inconvenient for workers to disassemble and install the positioning shaft or change the specifications of the positioning shaft, which makes it inconvenient to fix cylinders of different specifications and dimensions with tooling. Utility Model Content

[0005] The purpose of this utility model is to provide a tooling for locating and machining cylinder bearing holes. It solves the problem that when assembling the diamond pin and locating shaft onto the locating seat and fixing the locating seat onto the base plate, the existing technology makes it inconvenient for operators to disassemble and install the locating shaft or change its specifications when machining cylinders of different sizes. This makes it difficult to fix the tooling for cylinders of different sizes.

[0006] To achieve the above objectives, this utility model provides a tooling for locating and machining cylinder bearing holes, including a base and structural components. The structural components include a fixed block, a positioning shaft, a vertical block, a hydraulic cylinder, a pressure head, a moving block, an adjusting component, and a lifting component. The vertical block is slidably mounted on one side of the base. The positioning shaft is fixedly connected to the vertical block and located on the side of the vertical block away from the base.

[0010] The vertical block has a positioning groove, which is located on the side of the vertical block close to the fixed block and cooperates with the fixed block.

[0011] This utility model discloses a tooling for locating and machining cylinder bearing holes. A positioning shaft, suitable for the cylinder specifications, drives a vertical block into the mounting groove of a base. An adjusting motor drives an adjusting screw to rotate on the base. When the adjusting screw rotates, it drives a moving block to move on the base.

The lifting component adjusts the position and height of the hydraulic cylinder 105, and the hydraulic cylinder 105 drives the pressure head 106 to fix the cylinder on the base 101. This allows the tooling to be used to fix cylinders of different specifications and sizes.

[0021] The vertical block 104 is slidably mounted on one side of the base 101.

The lifting component is connected to the bottom of the hydraulic cylinder 105. The lower right side of the pressure head 106 is connected to the output end of the hydraulic cylinder 105. By using the positioning shaft 103, which is suitable for the cylinder specification, to drive the vertical block 104 into the mounting slot of the base 101, the adjusting component drives the moving block 107 to move the fixed blocks 102 on the base 101, driving the fixed blocks 102 to insert into the positioning slot of the vertical block 104, fixing the vertical block 104 on the base 101, and then installing the positioning shaft 103. Conversely, disassembly is performed, and the cylinder bore of the cylinder is guided into the head of the positioning shaft 103. The lifting component adjusts the position and height of the hydraulic cylinder 105. The hydraulic cylinder 105 drives the pressure head 106 to fix the cylinder on the base 101, thereby enabling the tooling to fix cylinders of different specifications and sizes.
