Description

Technical Field

[0001] This utility model relates to the field of mechanical remanufacturing technology, specifically a repair device for scratches on the inner and outer surfaces of a cylinder body. Background Technology

[0002] Remanufacturing is an industry that uses high technology to repair and transform waste products. It targets damaged or soon-to-be-scrapped parts. Based on performance failure analysis and life assessment, remanufacturing engineering is designed and a series of related advanced manufacturing technologies are adopted to make the quality of remanufactured products reach or exceed that of new products. Remanufacturing engineering is a systematic project that takes into account the entire life cycle management of product parts. It uses original parts and remanufacturing forming technology (including advanced surface engineering technology and other processing technologies) to restore the size, shape and performance of the parts and form remanufactured products.

[0003] The remanufacturing of cylinder blocks includes processes such as target object inspection, remanufacturing component classification, and remanufacturing technology selection. Most of these processes are carried out on machine tools, while most other processes can be completed in environments other than machine tools. For example, target object inspection includes roundness, cylindricity, flatness, straightness, line profile, surface profile, fatigue spalling, corrosion pitting, cracks, scratches, crack flaw detection, coating, and welding. However, cylinder blocks are heavy, and flipping them requires the assistance of machine tools, which occupies machine tools. Therefore, this application is made. Utility Model Content

The frame 1 is provided with a horizontally movable cylinder clamping component 7 and a cylinder translation component 6. A honing machine 9 is mounted on the tail mounting bracket 8. The hydraulic cylinder is lifted and moved to the top of the equipment by a crane. The chuck 3 clamps the piston rod end of the hydraulic cylinder, and the translation component 6 clamps and fixes the outer side of the cylinder barrel. Concentricity calibration is performed using a micrometer. The drive motor a5 drives the chuck 3 to rotate via the gearbox 4, causing the hydraulic cylinder to rotate. In the detection of roundness, cylindricity, flatness, straightness, line profile, surface profile, fatigue spalling, corrosion pitting, cracks, scratches, crack flaw detection, coating, and welding, it can completely replace the basic functions of machine tool positioning and rotation.

[0020] In a preferred embodiment, the cylinder clamping component 7 includes a sliding clamp 701, a movable bracket 702, a roller clamp 703, and a control screw 704. The frame 1 is made of H-beam. The sliding clamp 701 is movably clamped on the frame 1. A slidable movable bracket 702 is mounted on the sliding clamp 701. A rotatable roller clamp 703 is mounted on one side of the movable bracket 702, and the other side is connected to the sliding clamp 701 via the control screw 704. There are two cylinder clamping components 7, which are respectively mounted on the two sides of the frame 1, for a total of four cylinder clamping components. The rectangular roller clamp 703 clamps and positions the hydraulic cylinder. The roller clamp 703 can rotate by rolling. After being clamped and fixed on the outside of the cylinder barrel, the drive motor a5 drives the chuck 3 to rotate through the gearbox 4, thereby driving the cylinder to rotate. The roller clamp 703 rotates automatically during the rotation of the cylinder, achieving the rotational requirement of the cylinder while positioning. The movable bracket 702 can be adapted to cylinders of different diameters under the adjustment of the control screw 704, and can be adjusted and assisted in the concentricity calibration process of the micrometer.

[0021] In a preferred embodiment, the sliding clamp 701 is horizontally movable to the frame 1 via the slide rail 11. The movable configuration of the sliding clamp 701 can accommodate cylinders of different lengths.

[0022] In a preferred embodiment, each movable support 702 is rectangular, and there are two movable supports 702 symmetrically distributed vertically. The movable supports 702 pass through the sliding clamp 701 and can slide relative to each other. The roller clamp 703 and the control screw 704 are located on both sides of the sliding clamp 701, and there are two roller clamps 703, which are symmetrically distributed front and back. Each roller clamp 703 is equipped with two roller clamps 703 symmetrically distributed vertically, so as to perform four-point positioning of the cylinder and stabilize and limit the cylinder.

[0023] In a preferred embodiment, the control screw 704 is threadedly connected to the movable bracket 702, and the control screw 704 is rotatably connected to the sliding clamp 701 via a bearing. Rotating the control screw 704 drives the movable bracket 702 to move, and controlling the roller clamp 703 to clamp the cylinder. The roller clamp 703 is a hollow roller and is rotatably connected to the movable bracket 702 via a bearing.

The threaded sleeve 603 is internally threaded with the drive screw 601, which is rotatably connected to the bearing and bearing housing 602. After the cylinder clamping component 7 clamps the cylinder, the cylinder clamping component 7 can be translated by the cylinder translation component 6, which drives the cylinder clamping component 7 to move horizontally and extend and retract the cylinder, facilitating operation and measurement by the operator.

[0025] In a preferred embodiment, one end of the drive screw 601 is connected to the output shaft of the drive motor b12, which is fixed on the frame 1.
