Description

Horizontal tail large shaft shot blasting clamp

Technical Field

The utility model relates to an aviation peening anchor clamps field, concretely relates to big axle peening anchor clamps of horizontal tail.

Background

The horizontal tail large shaft of the airplane is an important structural member for connecting the airplane body and the horizontal tail, and the reliability of the horizontal tail large shaft directly influences the safe use of the airplane. The failure property of the horizontal tail large shaft is generally corrosion fatigue fracture, cracks originate from the positioning welding point between the bushing and the cylinder body, and the cracks are initiated at the welding point too early under the action of working load. The surface defect is one of the dangerous factors for the breakage of the large shaft, and the shot blasting process is a surface strengthening process and can effectively improve the mechanical strength, the wear resistance, the fatigue resistance, the corrosion resistance and the like of the horizontal tail large shaft.

In the shot blasting process, in order to improve the process efficiency of shot peening treatment, a tool clamp of a product is a very important process auxiliary, and the quality of the clamp directly determines the shot blasting effect of the product and the labor condition of an operator.

SUMMERY OF THE UTILITY MODEL

In order to solve the big axle of horizontal tail of aircraft and in peening process, need carry out even shot-peening strengthening in putting into shot-peening strengthening equipment with the product is vertical, simultaneously under the prerequisite of guaranteeing product size precision and peening effect, effectively guarantee that the product does not empty, not receive the anchor clamps scratch and collide with, the utility model provides a big axle shot-peening anchor clamps of horizontal tail.

The technical scheme of the utility model as follows: a horizontal tail large shaft shot blasting clamp is of a symmetrical structure and comprises a vertical seat, 2 clamping hands and a protective sleeve;

the vertical seat comprises a base 1, 2 welding plates 2, a support 3, 2 angle irons 4 and 4 angle irons 5; four corners of the base 1 are respectively provided with a U-shaped groove; the 4 angle steels 5 are arranged in a rectangular shape, and one end of each angle steel is vertically welded on the base 1; in the width direction, the other end of each two angle steels 5 is vertically welded with an angle iron 4, and the middle of the vertical side of the angle iron 4 is provided with an open slot; the end part between the two angle irons 4 is welded through the welding plate 2; a gap is formed between the support 3 and the base 1, and two ends of the gap are respectively fixed on the angle steel 5; the middle of the support 3 is provided with a through hole.

The clamping hands are positioned on the angle iron 4, and an inner hole formed by combining the two clamping hands is of a circular hole structure; each clamping hand comprises 2 corner fastening blocks 6, a handle 7 and a clamping head 8; the handle 7 is positioned in an open slot of the angle iron 4; the chuck 8 is screwed on the handle 7; the two sides of the chuck 8 are respectively welded with an angle-shaped fastening block 6, and the angle-shaped fastening block 6 is provided with an open U-shaped groove; the bolt 12 and the nut 13 pass through the U-shaped groove and are used for connecting the two clamping hands;

the protective sleeves comprise a long protective sleeve 9 and a short protective sleeve 10; the long protective sleeve 9 passes through a through hole on the support 3, and the bottom end of the long protective sleeve is connected to the base 1 through a screw 11; the short protective sleeve 10 is used to protect a product.

The gap between the support 3 and the base 1 is selected to be 30mm.

The two sides of each of the 2 clamping hand components are respectively connected with the clamping hand towards the center in a clamping way through an opening U-shaped groove of the angle-shaped fastening block 6 on the clamping head 8 by bolts 12 and nuts 13; the handle 7 is positioned in the open slot on the angle iron 4 to limit left and right and front and back.

The critical aperture of the long protective sleeve 9 and the short protective sleeve 10 is determined by the characteristics of the matched product and the size of the shaft diameter.

The utility model has the advantages that: the utility model discloses satisfying under the above-mentioned technical requirement prerequisite, adopting a simple high-efficient clamp to press from both sides tightly, fixed method, designed a big axle peening anchor clamps of horizontal tail, make the product keep accurate and stable position in peening equipment, strengthen providing effective guarantee for stable even acceptance peening of peening in-process product. The clamp is suitable for shot blasting procedures of the large horizontal tail shafts with various shaft diameter sizes, the clamp is used for realizing the rapid clamping of the large horizontal tail shafts in the shot blasting procedures, products are effectively prevented from being toppled over, scratched and collided by the clamp, and the efficiency and the quality of shot blasting are improved.
