Description

Technical Field

[0001] The utility model belongs to the technical field of honing tools, and particularly relates to a honing tool for non-circular hole machining. Background Technique

[0002] Precision machining of non-circular special-shaped inner holes is an inner hole machining technology with great implementation difficulty. The biggest difference between it and circular inner hole machining is that non-circular inner hole machining not only needs to control the size of the inner hole diameter of the part, but also needs to control the contour accuracy of the inner hole of the part. High-precision non-circular cross-section machining often adopts a micro-feed mechanism, generally realized by methods such as elastic deformation, mechanical profiling, eccentric spindle or eccentric tool bar.

[0003] A honing tool for non-circular hole machining according to a formula (publication number: CN 105234800B): includes a tool body, a wedge-shaped tool expanding component installed on the inner wall of the tool body, the tail of this component is connected to an axial feed component, a main oilstone seat connected to the wedge-shaped tool expanding component, a compensation mechanism composed of a compensation oilstone seat, an actuator group, a support rod and a tool retracting spring ring, a compensation oilstone is installed on the compensation oilstone seat, the compensation oilstone seat and the support rod are connected to the actuator group, and the tool retracting spring ring is pressed against both ends of the compensation oilstone seat, the support rod and the main oilstone seat.

[0004] In the above application, through the mutual cooperation of the wedge-shaped tool expanding component and the actuator component, when the wedge-shaped tool expanding component processes the inner hole for a long time, it is difficult to solve the function of lubricating it, resulting in excessive wear of the wedge-shaped tool expanding component and reducing the service life of the tool. Therefore, we propose a honing tool for non-circular hole machining. Content of the Utility Model

[0005] The purpose of the utility model is to provide a honing tool for non-circular hole machining. Through the mutual cooperation between components such as the oil tank, oil delivery channel and oil outlet of the lubrication mechanism, the staff first adds lubricating oil to the inside of the oil tank through the oil filling port, then starts the motor to make the lubricating oil inside the oil tank enter the oil chamber under extrusion force, and then lubricates the fixed blade and the moving blade through the oil delivery channel and the oil outlet. When the force rod is not stressed, the extrusion plate is reset through the second return spring. Such a design realizes the effect of indirectly lubricating the blade, can reduce the cutting force, friction and power consumption, reduce tool wear, and solves the existing problems.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

The function of providing an oil outlet on the side of the fuel tank is to convey lubricating oil into the fuel tank.

[0014] Further, the bottom of the force rod is located on the displacement track of the knocking rod. The number of the oil delivery channels is set to ten and they are circumferentially arranged in an array along the circumferential surface of the tool rest. The function of the bottom of the force rod being located on the displacement track of the knocking rod is to ensure that when the knocking rod rotates, it can knock the force rod. The function of setting the number of the oil delivery channels to ten and arranging them in a circumferential array along the circumferential surface of the tool rest is to lubricate each tool evenly.

[0016] Through the mutual cooperation among components such as the motor, the fixed blade and the movable blade of the blade adjusting mechanism of the utility model, when a honing tool needs to be used, the staff can adjust the honing tool according to the processing requirements. By starting the motor, the movable blade is pushed by the annular push plate and slides inside the moving groove, thereby adjusting the size of the inner hole processing. When the annular push plate leaves the bottom of the movable blade, the movable blade is reset through the first reset spring. Such a design realizes the effect of automatically adjusting the processing size and effectively improves the flexibility of the honing tool.

[0017] Through the mutual cooperation among components such as the fuel tank, the oil delivery channels and the oil outlet of the lubricating mechanism of the utility model, the staff first adds lubricating oil into the fuel tank through the oil outlet. Then, by starting the motor, the lubricating oil inside the fuel tank is subjected to extrusion force and enters the oil storage chamber. Then, the fixed blade and the movable blade are lubricated through the oil delivery channels and the oil outlet. When the force rod is not stressed, the extrusion plate is reset through the second reset spring. Such a design realizes the effect of indirectly lubricating the blade, which can reduce the cutting force, friction and power consumption and reduce the tool wear.
