Technical Field
The utility model relates to a honing equipment field, especially a terminal surface honing sword.
Background
Honing is a finishing process of finishing a finish-machined surface with a whetstone (also called a honing bar) mounted on a honing head. The contact area between the honing and the hole surface is large, and the processing efficiency is high. Under certain conditions, the size precision of the hole after the plane honing can be processed to be IT 7-4 level. The main improvement of the honing machine at the present stage is to increase the processing speed or to increase the stability in the whole machine processing so as to improve the product quality.
In the field of mechanical equipment processing, for a matching coupling part of a friction pair, an extreme pressure oil film (such as between an engine cylinder hole and a piston ring) is formed on the surface of the friction pair to keep long-term and stable running. For many end face friction pairs, when an extreme pressure oil film is formed on a friction surface, patterns are ground on the end face of a part and certain lines and depth are kept, and for parts which are relatively regular, a universal cylindrical grinding machine or an end face grinding machine can be used for solving the problem. However, for irregular parts and small batches of parts, the investment in a universal cylindrical grinding machine or face grinding machine is expensive, and a special fixture is required. The machining precision is not easy to guarantee, and the manufacturing cost is high. The existing equipment lacks processing equipment for the end surface friction pair surfaces of irregular parts and small-batch parts.

Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
Example 1
An end face honing tool is designed to comprise a step-shaped tool shank shaft 1, a sliding key groove is arranged on the tool shank shaft 1, a positioning end cover 8 and the tool shank shaft 1 connected with a power source are arranged at the shaft end on one side of the sliding key groove, a spring 5 is arranged at the other end of the sliding key groove, and a floating tool body 3 is arranged at the other end of the spring 5; the floating cutter body 3 is cylindrical, the inner wall of the floating cutter body is sleeved outside the cutter handle shaft 1, a floating cutter head 6 is arranged on the end face of the plugging end of the floating cutter body, at least two through holes are formed in the floating cutter body 3 for installing positioning keys, and the corresponding positioning keys are arranged between the through holes and the sliding key 4 grooves; and a limiting nail 2 for limiting the rotation of the floating cutter body 3 is arranged between the positioning end cover 8 and the floating cutter head 6 so as to form a buffer gap A between the floating cutter body 3 and the positioning end cover 8. The limit nail 2 is arranged in a mounting hole reserved in the positioning end cover 8 in a sleeved mode and is in threaded connection with the floating tool bit 6 and the positioning key.
The working process comprises the following steps of firstly determining the type of a spring 5, the length of a floating tool bit 6 and the diameter and the length of a tool shank shaft 1 according to the condition of a machined plane, forming a set of table standards in a long-term process, taking reference at any time to ensure that when a surface with a certain depth is machined, the length of the floating tool bit 6 is enough to enable the floating tool bit 6 to go deep into the depth surface, the elasticity of the spring 5 is enough to support a buffer gap and reset, then installing the floating tool bit 6 at the plugging end of the floating tool bit 6 according to the machining requirement, installing a key connection for positioning, playing a role of auxiliary positioning by a positioning nail to ensure the formation of the buffer gap A, finally determining the rotating direction and the rotating speed of the floating tool bit 6 according to the condition of a machined.
The floating cutter head 6 is cuboid, the length of the floating cutter head is larger than the radius of the blocking end of the floating cutter body 3, the floating cutter head and the radius form an inclination angle larger than 10 degrees and are arranged at the blocking end, and at least 3 floating cutter heads 6 are arranged on the further blocking end. This design can ensure high efficiency and high precision honing while maintaining the stability of the floating cutter head 6 in the working process.
The buffer gap a is less than 2 cm. In this embodiment, the thickness is maintained within 0.5 cm. When the floating tool bit 6 enters the cutting surface, the tool bit can retreat by 0.5cm under the impact force, so that the floating tool bit 6 is protected, and the service life of the floating tool bit 6 is prolonged.
