Description

Technical Field

[0001] The present invention relates to the technical field of precision machining, and in particular to a cutting device for machining a plunger pump cylinder. Background Art

[0002] As the core component of the hydraulic system, the plunger pump cylinder faces the following common industry challenges in its processing:

[0003] 1. The contradiction between precision and deformation, specifically manifested as follows: the cylinder body is mostly a thin-walled deep-hole structure (wall thickness is usually <10mm), and traditional external clamping fixtures are prone to clamping deformation. Cutting vibration further causes roundness deviation (>0.05mm) or dimensional fluctuations, affecting sealing and life.

[0004] 2. The efficiency of multiple processes is low, which is manifested in the following aspects: internal hole boring, end milling, radial drilling and other processes need to be completed in sequence. Each process requires re-clamping and positioning. The processing time accounts for more than 40% of the total working hours, and the cumulative repeated positioning error is more than 0.1mm.

[0005] 3. Equipment functional limitations, specifically: general machine tools lack multi-axis linkage capabilities, complex features (such as inclined oil holes and stepped inner cavities) require multiple adjustments to the workpiece posture or replacement of special equipment, and the degree of flexibility is low.

[0006] 4. The cost of specification adaptation is high. Specifically, the inner diameter (Φ30–Φ150mm) and height (50–300mm) of different cylinder models vary greatly. Traditional fixture and tool replacement takes up to 30 minutes per time, which restricts small-batch and high-variety production.

[0007] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Summary of the Invention

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] This invention utilizes an integrated workbench design to achieve full automation of the machining process. Specifically, the cutting workbench integrates four functional modules: conveying, clamping, steering, and machining, reducing equipment footprint and optimizing production processes. Each process, including cylinder loading, internal clamping, transfer positioning, two-stage clamping, multi-directional machining, and unloading, is fully automated, significantly reducing manual intervention.

[0037] The present invention can achieve precise positioning and anti-deformation control of the plunger pump cylinder. Specifically,

[0038] The present invention adopts a two-stage clamping system. When loading, the support tray and the annular limit plate provide basic positioning, and four sets of electric telescopic clamps achieve preliminary fixation to support and position the lower part of the cylinder body; during processing, the positioning fork arm is extended by the electric-controlled telescopic module to perform secondary reinforcement on the upper part of the cylinder body, effectively suppressing deformation caused by cutting vibration.

[0039] The present invention has multi-degree-of-freedom machining capabilities. Specifically, the steering transmission assembly drives the second transmission wheel via a transmission belt, driving the support tray and workpiece to rotate around the axis, enabling rotational positioning. The lifting and telescopic cylinder achieves vertical displacement of the workpiece, adapting to different machining height requirements, thereby achieving flexible adjustment of the workpiece posture. The rotary tool holder (driven by a stepper motor) cooperates with the traverse slide to feed horizontally to complete inner wall cutting. The side tool holder / center tool holder (driven by a rotary drive motor) cooperates with the lifting slide to feed vertically to complete end face or deep hole cutting. The rolling drive motor controls the overall rotation of the steering mounting seat to achieve machining at any position in the circumferential direction, thereby realizing multi-directional motion adjustment of the tool.

[0040] This invention enables efficient tool switching and multifunctional machining. Specifically, by flipping the base 180° and rotating it counterclockwise, radial tools (rotating toolholders) and axial tools (side toolholders / center toolholders) can be switched. The modular toolholder design (side toolholders, center toolholders, and rotating toolholders) supports the installation of multiple tool types to meet the needs of different processes. Furthermore, multiple processes such as radial boring and axial drilling / milling can be completed in a single clamping operation, reducing re-positioning errors.

[0041] The limiting right-angle plate provided in the present invention cooperates with the limiting slot of the lifting slide to ensure that there is no deviation during the lifting process; the constraint plate guides the horizontal movement of the transverse slide to ensure feeding accuracy; the sprocket transmission mechanism realizes the synchronous drive of multiple conveying rollers to ensure the stability of loading; the top supporting triangular prism is telescopically set on the central square column, which can be adapted to the internal support clamping of cylinders with different inner diameters; the annular limiting plate supporting the pallet is combined with the electric telescopic clamping block to be compatible with a variety of outer diameter sizes.
