Description

Technical Field

[0001] The utility model belongs to the technical field of honing machines, and particularly relates to a deep-hole honing machine for processing hydraulic cylinder barrels. Background Art

[0002] Honing machines are mainly used for precision finishing and ultra-precision finishing of the inner holes of precision parts. During the honing process of workpieces, special honing oil is used for cooling, and the deformation is also small, so high dimensional accuracy, geometric accuracy and surface roughness can be obtained. It is an important process means for efficiently processing precision inner holes and long holes. And because the workpiece and the honing head make relative reciprocating and rotating movements during honing, the machined surface of the workpiece has crosshatch patterns, which is conducive to maintaining the lubricating oil film and eliminating the phenomenon of embedded abrasive after grinding, thereby improving the service life. It is mainly used in the manufacturing of automotive parts and hydraulic component enterprises.

[0003] At present, most of the existing deep-hole honing machines clamp workpieces by hydraulic pressing, which is easy to cause workpiece deformation and affect product quality. And honing oil mainly includes two categories: lubricating oil and cutting oil. For hydraulic cylinder barrels with both ends open, lubricating oil needs to be injected from both ends during honing to facilitate lubrication, cooling and slag discharge. At present, it is mostly manual oil injection, which is labor-consuming and has certain safety risks.

[0004] Therefore, it is urgent to improve. Content of the Utility Model

The specific steps are as follows: by controlling the output shaft of the reduction motor to rotate forward or reverse, the bidirectional screw rod is driven to rotate, and then the two slides are driven to move closer or farther away from each other, so as to adjust the spacing between the two support frames, that is, adjust the spacing between the two support wheels; then the hydraulic cylinder is moved between the two support frames and the reserved The hydraulic cylinder is passed under the fixed belt, and then the front and rear ends of the hydraulic cylinder are placed on the two supporting wheels of the corresponding side clamping assembly respectively to ensure that the axis of the hydraulic cylinder coincides with the axis of the honing head. Then the winding motor is controlled to drive the traction wheel to wind up and tighten the fixed belt so that the fixed belt can be tied from the top of the hydraulic cylinder. After that, the support plate and the grinding rod box are driven forward by the stepper motor, and the inside of the hydraulic cylinder is honed by the honing head.
