Description

A new test jig for shot peening cleaning of thin plates

technical field

The invention relates to the technical field of mechanical manufacturing, in particular to a novel thin-plate shot-blasting fixture for testing.

Background technique

Shot peening is to spray high-speed projectiles onto the surface of the workpiece to cause plastic deformation on the surface of the workpiece and form a strengthening layer with a certain thickness. It is one of the effective methods to improve the fatigue life of parts. Shot peening can also use the impact and friction of iron shot Function, remove rust and other pollution on the metal surface, and get a certain roughness, revealing the true color of the metal. The angle between the nozzle and the test piece has a certain influence on the surface roughness of the test piece after shot peening. In order to obtain a surface with different roughness, it is necessary to adjust the angle between the nozzle and the test piece during the shot peening process. Adjustment, the current method of adjusting the required angle is obtained by adjusting the inclination of the nozzle. The process requires loosening the nut and then tightening the nut. The process is cumbersome and easy to damage, so that the nozzle will loosen due to the relatively large jet reaction force during the working process. Therefore, it is extremely important to obtain the required angle between the nozzle and the test piece by adjusting the angle of the test piece. The design of a new type of thin plate shot peening fixture for testing will solve the above problems well.

Contents of the invention

The object of the present invention is to provide a new type of thin-plate shot-peening fixture for testing that can more conveniently and quickly adjust the distance between the test piece and the nozzle during the shot-peening process.

The technical solution adopted in the present invention is: a new type of thin plate shot blasting cleaning fixture for testing, including clamping elements, angle instrument boards, pin shafts and rotating bottom plates, characterized in that: the clamping elements include long grooves, clamping blocks , test piece groove, long bolts and clamping nuts; through holes are provided on the two side walls of the long groove, through holes are provided on the clamp block, and the long groove and the clamp block pass through the long bolts connected, the specimen groove is fixed on the long groove, and the clamping nut cooperates with the long bolt; 9 through holes are evenly distributed on the angle instrument panel, and there are holes of a certain depth on both sides of the rotating bottom plate. light hole; the angle instrument panel is connected with the rotating base plate through a pin shaft.

The technical features of the present invention are: the long groove is fixed on the rotating bottom plate; a rectangular groove with a certain depth is arranged in the middle of the test piece groove; the through holes on the long groove are symmetrical about the center line.

The technical feature of the present invention is that one end of the rotating bottom plate is relatively fixed to the position of the angle instrument panel, and the other end can rotate freely.

The technical feature of the present invention is that the total scale of the angle instrument panel is 90 ^° .

The beneficial effects of the invention are: 1) simple structure, convenient installation and use; 2) adjusting the angle between the test piece and the nozzle by adjusting the position of the pin shaft, which is more convenient and quick, and improves the versatility and adaptability of the machine.

Description of drawings

Fig. 1 is a three-dimensional structure diagram of an embodiment of the present invention.

Fig. 2 is a three-dimensional schematic view of a sample holder according to an embodiment of the present invention.

Among them, 1 is a long groove, 2 is a clamp block, 3 is a rotating bottom plate, 4 is a test piece groove, 5 is an angle instrument plate, 6 is a pin shaft, 7 is a long bolt, and 8 is a clamping nut.

Detailed ways

The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings.

As shown in FIG. 1 , a novel thin plate shot peening fixture for testing of the present invention includes a clamping element, an angle gauge plate 5 , a pin shaft 6 and a rotating bottom plate 3 . Wherein, the clamping element includes a long groove 1, a clamp block 2, a specimen groove 4, a long bolt 7 and a clamping nut 8; the two side walls of the long groove 1 are provided with through holes, and the clamp The block 2 is provided with a through hole, the long groove 1 is connected with the clamp block 2 through the long bolt 7, the test piece groove 4 is fixed on the long groove 1, and the clamping nut 8 is connected with the long groove 1. The bolts 7 cooperate; 9 through holes are evenly distributed on the angle meter plate 5, and light holes of a certain depth are provided on both sides of the rotating bottom plate 3;

In the present invention, the long groove 1 is fixed on the rotating bottom plate 3; a rectangular groove with a certain depth is provided in the middle of the test piece groove 4; the through hole on the long groove 1 is symmetrical about the center line.

In the present invention, one end of the rotating bottom plate 3 is relatively fixed to the angle plate 5 , and the other end can rotate freely.

In the present invention, the total scale of the angle instrument panel 5 is 90 ^° .

The working process of the present invention is: as shown in Figure 1, fix the long groove 1 on the rotating bottom plate 3, then fix the test piece groove 4 on the long groove 1, and then put the cut test piece into the test piece. In the rectangular groove in the middle of the part groove 4, at this time, the clamp block 2 is close to the two sides of the test piece, and the clamp block 2 is adjusted at the same time so that its through hole is aligned with the through hole on the long groove 1, and then the long bolt 7 Go through the through hole on one side of the long groove 1 and the through hole of the clamp block 2 in sequence. At this time, screw the clamping nut onto the long bolt 7, and then pass the long bolt 7 through the through hole on the other side of the long groove 1, and then pass the screw Tighten the clamping nut 8 to realize the clamping of the test piece, and finally adjust the angle of the rotating bottom plate 3 by adjusting the pin shaft 6, and then obtain the required angle between the nozzle and the test piece.

The above description is only a specific embodiment of the present invention, but not a limitation of the present invention.
