Description

Honing head structure

Technical Field

The application relates to the field of honing, in particular to a honing head structure.

Background

The traditional honing head mainly aims at the ultra-precision grinding design structure of the inner hole of a hydraulic oil cylinder barrel and a straight through hole part, and at present, no honing head specially designed for blind holes, particularly spherical blind holes, exists.

Disclosure of Invention

The application provides a honing head structure, it can effectively realize reducing the step of manual work processing sphere blind hole to the precision finishing of sphere blind hole.

The application particularly relates to a honing head structure which comprises a core bar, a support sleeve, a rolling bearing, an end face bearing, a honing head body, precision polishing gauze and a pressing piece; the support sleeve is sleeved on the periphery of the core rod, and a rolling bearing and an end face bearing are respectively arranged between the support sleeve and the core rod; one end of the core rod is connected with a grinding head body, the grinding head body comprises a linear part and a spherical part, the periphery of the spherical part is sleeved with precision polishing gauze, and the spherical part and the precision polishing gauze are tightly combined through a pressing piece.

Preferably, the rolling bearing and the end face bearing are respectively located at two end positions inside the support sleeve.

Preferably, one end of the core bar, which is far away from the honing head body, is provided with a connecting piece connected with a honing rod of the honing machine.

Preferably, the longitudinal width of the straight line part is 1/2-1 times of the spherical radius of the spherical part.

Preferably, the support sleeve is a nylon support sleeve.

This application honing head structure adopts the bistrique body to be provided with straight line portion and sphere portion, utilizes the periphery cover of sphere portion to establish the precision finishing gauze to this precision finishing who realizes the sphere blind hole reduces manual operation's step.

When the honing head structure is used, the use method is as follows: the honing rod of the honing machine is connected with the core rod, and the honing rod rotates to drive the grinding head body to rotate so as to realize the spherical grinding of the inner hole. Compare in current manual operation mode, interior blind hole tip is interior sphere, and hole and interior sphere all need honing process, and after this hole processing technology was the honing, interior sphere ground with self-control frock hand, and the quality is extremely unstable, and endoscopy is often reworked. After the spherical honing head is applied, the processing period is obviously shortened, and the processing quality and the matching precision are improved.

Drawings

In order to more clearly explain the technical solution of the present application, the drawings needed to be used in the embodiments will be briefly described below, and it is obvious to those skilled in the art that other drawings can be obtained according to the drawings without any creative effort.

Figure 1 is a schematic cross-sectional view of a honing head construction according to the invention.

Detailed Description

For the sake of understanding, the following description will be made with reference to the drawings on the structure of the switch power supply system for rail systems according to the present application.

As shown in fig. 1, fig. 1 is a schematic cross-sectional view of a honing head structure according to the invention. The honing head structure comprises a core bar 1, a support sleeve 3, a rolling bearing 2, an end face bearing 4, a grinding head body 5, precision polishing gauze 6 and a pressing piece 7; the support sleeve 3 is sleeved on the periphery of the core rod 1, and a rolling bearing 2 and an end face bearing 4 are respectively arranged between the support sleeve 3 and the core rod 1; one end of the core bar 1 is connected with a grinding head body 5, the grinding head body 5 comprises a linear part 5-1 and a spherical part 5-2, the periphery of the spherical part 5-2 is sleeved with a precision polishing gauze 6, and the spherical part 5-2 and the precision polishing gauze 6 are tightly combined through a pressing piece 7.

The rolling bearing 2 and the end face bearing 4 are respectively positioned at two ends inside the supporting sleeve 3; one end of the core bar 1 far away from the grinding head body 5 is provided with a connecting piece connected with a honing rod of the honing machine; the longitudinal width of the straight line part 5-1 is 1/2-1 times of the spherical radius of the spherical surface part 5-2; the support sleeve 3 is a nylon support sleeve. With the preferred arrangement, the damage probability of the structure of the obtained honing head is reduced, and the service life is longer.
