[0002] In the field of mechanical processing, traditional boring machines often struggle to meet the high precision and efficiency requirements for machining special-shaped workpieces. Existing boring machines typically use simple blocks and fixtures to secure the workpiece, but these structures have limitations in positioning accuracy, clamping speed, and adaptability. For example, traditional blocks and fixtures may not be able to quickly adapt to workpieces of varying shapes and sizes, resulting in extended preparation times before machining. Furthermore, due to insufficient positioning accuracy, the workpiece may shift or deform during machining, affecting machining quality. Furthermore, traditional clamping mechanisms can damage the workpiece surface, reducing its surface quality.

[0003] In order to solve the above problems, the utility model proposes a piston boring machine for processing special-shaped workpieces, which aims to improve the positioning accuracy, processing efficiency and surface quality of the workpieces while reducing operation risks and maintenance costs.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figure 1-2This utility model provides a technical solution: a piston boring machine for machining irregularly shaped workpieces. In modern manufacturing, the demands for machining irregularly shaped workpieces are becoming increasingly stringent, requiring not only precision but also efficiency and equipment innovation. To meet these demands, a piston boring machine specifically designed for machining irregularly shaped workpieces has emerged. The design of this boring machine fully considers the unique characteristics of irregularly shaped workpieces. Through a series of sophisticated mechanical structures and an innovative clamping mechanism, it achieves high-precision workpiece positioning and efficient machining.

[0018] First, the boring machine's worktable 1 is the foundation of the entire machine. It must possess sufficient strength and stability to withstand the cutting forces and vibrations during the entire machining process. The worktable 1 is designed from high-strength cast iron and undergoes precision machining and heat treatment to ensure excellent flatness and stability. The first and second stops 2 and 3 are located on the worktable 1, which together form the initial positioning system for the workpiece.

[0019] The first stopper 2 utilizes an L-shaped design, effectively limiting workpiece movement in both directions and ensuring stability during machining. The second stopper 3, however, utilizes a plate-shaped design. Two second stops 3 are arranged so that their extensions align with the two right-angled edges of the first stopper 2, further enhancing workpiece positioning accuracy. The presence of two second stops 3 further stabilizes workpiece vertical positioning and facilitates the rapid replacement of workpieces of varying sizes.

[0020] To achieve high-precision machining on the boring machine, the worktable 1 is equipped with a first linear slide 4 and a second linear slide 5. The extensions of these two sets of slides are perpendicular to each other, forming a precise coordinate system that enables the boring machine to perform high-precision linear motion. Both the first and second linear slides 4 and 5 are equipped with support blocks 6. The design of these support blocks not only ensures the stability of the slides but also adapts to the requirements of different machining positions.

[0021] A locking rod 7 is threaded onto the support base 6. The lower end of the locking rod 7 abuts the corresponding slide rail. Rotating the locking rod 7 allows for quick securing and release of the slide rail, significantly improving machining efficiency. A toggle clamp 8 is located at the upper end of the support base 6. An L-shaped pressure block 9 is attached to the end of the toggle clamp 8. The pressure angle of the L-shaped pressure block 9 is aligned with the second stop 3, further improving workpiece positioning accuracy.

[0022] In order to protect the clamping surface from damage, the clamping surfaces of the first stopper 2 and the second stopper 3 are both provided with protective pads 10. The material of the protective pads 10 is usually selected from a material with moderate hardness and a certain degree of elasticity, such as rubber or polyurethane, which can protect the workpiece surface and reduce the damage to the workpiece surface caused by the clamping force.

[0023] Cam bearing followers 11 are installed at the ends of both the horizontal and vertical plates of the L-shaped clamp 9. This design enables bidirectional clamping of the workpiece. By rotating the cam, the cam bearing followers 11 can quickly clamp and release the workpiece, significantly improving machining efficiency. Furthermore, the design of the cam bearing followers 11 also takes into account the uniform distribution of clamping force, ensuring workpiece stability during machining.

[0024] In order to further protect the cam bearing follower 11, a polyurethane protective layer 12 is provided on its exterior. The polyurethane protective layer 12 not only prevents the metal parts from corrosion, but also absorbs some vibrations, reduces noise, and improves the comfort of the processing environment.

[0025] In addition, to accommodate workpieces of varying shapes and sizes, the boring machine is equipped with adjustable supports and fixtures. Through simple adjustments, it can quickly adapt to the processing requirements of different workpieces. This design greatly improves the versatility and flexibility of the boring machine, enabling it to meet the processing needs of a variety of complex workpieces.

[0026] The boring machine's control system uses an advanced CNC system that enables high-precision automatic positioning and machining path control. The CNC system automatically adjusts the boring machine's motion trajectory and speed based on the workpiece's machining requirements, ensuring high precision and efficiency during the machining process.

[0027] In short, the design of this piston boring machine for processing special-shaped workpieces fully considers the needs of modern manufacturing. Through a precise mechanical structure, innovative clamping mechanism and advanced CNC system, it achieves high-precision and high-efficiency processing of special-shaped workpieces. The emergence of this boring machine not only improves processing efficiency and reduces production costs, but also provides strong technical support for the development of modern manufacturing.

[0028] Working Principle: During operation, the boring machine table 1 serves as the foundation for the entire machine, securing and supporting other components. First and second stops 2 and 3 are mounted on the boring machine table 1 to position and secure the workpiece. Two second stops 3 are provided, and their extensions align with the two right-angled edges of the first stops 2, ensuring a stable workpiece position during machining.

[0029] A first linear guide rail 4 and a second linear guide rail 5 are mounted on the boring machine table 1, their extensions perpendicular to each other. They provide a path for the support base 6 to move, enabling precise positioning of the workpiece. The support base 6 is threaded onto the linear guide rails and equipped with a locking rod 7. The lower end of the locking rod 7 abuts against the corresponding guide rail, securing the support base 6 in place and preventing it from moving during machining.

[0030] A toggle clamp structure 8 is mounted on the upper end of the support base 6. An L-shaped pressure block 9 is mounted at its end. The L-shaped pressure block 9 is positioned adjacent to the second stop 3 to further secure the workpiece. Protective pads 10 are installed on the clamping surfaces of both the first and second stops 2, 3 to protect the workpiece surface from damage.

[0031] Cam bearing followers 11 are installed at the ends of the horizontal and vertical plates of the L-shaped clamp 9. These followers provide bidirectional clamping of the workpiece, ensuring stability during machining. A polyurethane protective layer 12 protects the cam bearing followers 11 from damage and reduces the risk of damage to the workpiece.

[0032] In summary, the piston boring machine ensures the stability and precision of special-shaped workpieces during the machining process through a series of positioning, clamping and protection components, while protecting the workpieces and equipment from damage.
