Abstract
The invention relates to a spray gun suitable for shot blasting for long and deep holes and inner holes of bent parts. A quick positioning block is arranged above an L-shaped connection frame, a V-shaped block is arranged below the connection frame, the upper portion of a spray gun body penetrates through the quick positioning block, and the lower portion of the spray gun body is attached to the interior of a V-shaped groove of the V-shaped block and positioned through a clamp arranged on the side end face of the V-shaped block. A nozzle is connected to the lower end of the spray gun body through a flexible joint, the opening of the nozzle is located in the outer periphery, the bottom of the nozzle is provided with a reflecting surface inclining upwards by 45 degrees, and the refraction position of the reflecting surface to the axis of the spray gun corresponds to the opening position of the nozzle. According to the spray gun, by adopting the special nozzle structure, the spray gun can be applied to shot blasting for the inner holes of the bent tubular parts and meet the requirement for the strength of shot blasting for the inner holes.
Description
Technical field
The invention relates to a kind of spray gun and ball blasting method thereof that is applicable to long deep hole, crooked class inner bore of part shot-peening, belongs to a kind of piece surface treatment process.
Background technology
Shot-peening is that to be widely used be the surface reinforcing method below a kind of recrystallization temperature, has been widely used at present the inner bore shot blasting intensive treatment of aircraft various stressed members, particularly undercarriage.In shot-peening process, bending area is difficult to 100% and covers, and repeatedly occurs that shot peening strength is unstable, causes undercarriage cannot meet drawing requirement, has had a strong impact on manufacturing schedule and a large amount of parts is scrapped.
Summary of the invention
The technical problem that the invention will solve is to provide a kind of spray gun and ball blasting method thereof that is applicable to long deep hole, crooked class inner bore of part shot-peening, this spray gun adopts special nozzle structure, can carry out shot-peening to the endoporus of bent tube form part, meet the requirement of inner bore shot blasting intensity.
For overcoming the above problems, the concrete technical scheme of the invention is as follows: a kind of spray gun that is applicable to long deep hole, crooked class inner bore of part shot-peening, above L-type link, be provided with quick locating piece, the below of link is provided with vee-block, the top of spray gun is through quick locating piece, below is fitted in the V-shaped groove of vee-block, and locates by the clip arranging on vee-block side end face; Lower end at spray gun connects nozzle by flexible joint, and the opening of nozzle, on excircle, and is provided with the reflecting surface of the 45° angle that is inclined upwardly in the bottom of nozzle, and reflecting surface is corresponding with nozzle opening position to the refraction position of spray gun axis.
The top of described nozzle is inserted in flexible joint, and is provided with chamfering at upper end of nozzle inwall.
Utilize above-mentioned spray gun to carry out the method for shot-peening, comprise the following steps:
1) spray gun is positioned by vee-block, and guarantee that spray gun overlaps with the V-shaped groove center line of vee-block, is then positioned at spray gun top on link by quick locating piece;
2) shot-peening part is vertically fixed in work chamber, according to different parts, the move distance of spray gun and the length of flexible joint is set;
3) the vertical sliding frame that is dynamically connected, drives the nozzle of spray gun and bottom to extend into inner bore of part, until reach shot-peening part bottom;
4) when nozzle moves up, start shot-peening, bullet stream vertically sprays from the opening of nozzle by the reflecting surface of 45° angle, and nozzle rotates and be vertical mobile, thereby completes the bead of part inwall.
This spray gun that is applicable to long deep hole, crooked class inner bore of part shot-peening, by the inclined-plane perflectometer that increases unidirectional 45 ° in nozzle, makes the inclined plane of shot-peening stream impact effect head change direction, the inwall of impingement holes.
Upper end of nozzle inwall is provided with chamfering, can reduce the kinetic energy loss of bullet, can effectively prevent that nozzle from being impacted to coming off by bullet.Reduce the wearing and tearing of flexible region simultaneously, guarantee the service life of nozzle.
The method of utilizing above-mentioned spray gun to carry out shot-peening adopts above-mentioned steps, nozzle not only can be extend into the endoporus of crooked part, and shot blasting effect is good, can meet shot peening strength requirement.
