Description
Technical Field
The utility model belongs to the mechanical cutting tool field, concretely relates to honing head for vertical honing machine.
Background
The inlet honing head matched with the inlet vertical honing machine is novel in structure and higher in honing precision, but has several problems:
1. once the inlet honing head is worn out, no honing head is available. The reasons are two: firstly, it is unrealistic to purchase the original-package imported honing head, because its purchase price is very high, and the manufacturing cycle is very long. In order to meet the requirements of processing various products in small batch, honing heads with various diameters and length specifications are needed, so that the purchase price of the honing head is extremely high, and the requirement of the processing progress of the product cannot be met; secondly, the purchase of domestic honing heads has a great problem. The german manufacturer of the vertical honing machine is bought by a certain company in China, and the domestic honing head is cheap relative to the imported honing head, but the purchase price of each honing head is still not cheap, and the honing head is also a great expense. The honing efficiency of honing the oilstone is extremely low, and the requirement of the production progress of the product cannot be met through multiple times of honing test verification after the formula of the oilstone is improved for multiple times.
2. The imported honing head has small wear limit of oilstone, and the oilstone and the honing sleeve need to be replaced frequently during use, so that the purchase cost is high. When the push rod for the expanding cutter is used for honing blind hole products, the taper of the push rod is small, and the lower end face of the push rod is flush with the lower end face of the honing head body, the oilstone is expanded by about 0.5mm (diameter direction) only on the basis of 0. After the oilstone is worn to exceed 0.5mm, the tool cannot be expanded and used any more, otherwise, the tool is collided, and the precision of the honing head and even the precision of the honing machine are damaged.
3. The imported honing head has high manufacturing precision, and the localization of the structure is very difficult. Such as: three grooves for mounting the expanding cutter block on the honing head body are uniformly arranged at 120 degrees, cannot be machined by a common slow-running wire cutting method, must be machined by special methods such as electric sparks and the like, and needs extremely high machining precision; the honing head body, especially the push rod in the honing head body is a super-thin long rod, the processing strength and the rigidity are not enough, but the processing precision is high, and the processing difficulty is high.
4. The imported honing head is not strong enough and is very fragile, and the precision of the imported honing head is damaged and even broken due to careless cutter collision in the honing process, so that the imported honing head cannot be used continuously.
In summary, based on the interface and the use requirement of the honing machine for installing the honing head, the honing head with the universal tool shank, the large wear limit of the oilstone, the easy manufacture, the low manufacturing cost, the high honing precision, the durability and the autonomous controllable honing technology needs to be designed.

The handle and the honing head body of the honing head are designed in a separated mode, so that the handle can be repeatedly used, the manufacturing cost is saved, the processing difficulty of the whole slender rod honing head body is reduced, and the manufacturing period is shortened.
2. A conventional oilstone seat type structure is adopted. The honing device has the advantages of mature structural design technology and manufacturing process, high honing precision, good stability, shorter manufacturing period, and lower manufacturing difficulty and manufacturing cost.
3. The wear limit of the oilstone is large. Under the condition of ensuring the strength of the feed cone of the expanded oilstone, the maximum taper is selected as far as possible, and the axial movement of the maximum taper can obtain a large cutter expanding amount by a small distance, so that a large oilstone abrasion limit is obtained.
4. The spring is replaced by a sealing ring. Because the honing head has small diameter and compact structure, parts such as the honing head body, the feeding cone, the oilstone seat, the spring and the like need to be arranged in a very small space range. In order to ensure enough strength of the honing head, the ring groove for mounting the spring cannot be too large, and a very small spring is required. And the elasticity and the durability of the undersized spring are poor, and the oilstone seat cannot be pressed back after the spring is used for a period of time. Therefore, in the embodiment, the spring is replaced by the common O-shaped sealing ring, and the O-shaped sealing ring is a wearing part and is prepared and replaced frequently.
5. And the two-section oilstone is used for realizing the honing of the blind hole. In order to recover the oilstone seat and the oilstone by using the spring, annular grooves are usually processed on the end surface of the bottom of the blind hole honing head body and the end part of the oilstone seat, and the spring or the sealing ring is placed on the annular grooves. However, the strength of the small-diameter honing head can be greatly weakened by the design, so that the honing head cannot meet the requirements on deformation and honing precision. Therefore, the structural design is innovated, and an annular groove for placing the sealing ring is arranged on the outer circle close to the end surface of the bottom of the honing head body. The problem of insufficient strength of the honing head is avoided through the two-section oilstone structure, and meanwhile, the processing difficulty and the manufacturing cost are reduced.
