Description
Technical Field
The utility model belongs to the technical field of the mechanical skill and specifically relates to a hang down straightness adjustment appurtenance for rotatory self tapping riveting.
Background
FDS (spin self-tapping riveting) is a novel connection process and can realize the quick connection of aluminum-aluminum and steel-aluminum. The screw generates heat through high-speed rotation, penetrates through the plate, is extruded and screwed into the plate to be connected under the action of huge axial pressure, and finally forms threaded connection between the plate and the screw, while the base material at the central hole is extruded out to form an annular sleeve at the bottom of the lower plate, so that the heat generated when the screw is used for self-tapping is fully utilized, and a tight connection joint is formed.
Although the FDS has high connection efficiency, the traditional verticality teaching is manually and visually taught, and the condition that a rivet is completely vertical to a part during riveting cannot be guaranteed, so that a mechanical device is needed for accurately adjusting the verticality.
Disclosure of Invention
The utility model discloses an overcome prior art not enough, provide a hang down straightness adjustment appurtenance for rotatory self tapping riveting, through the instrument of specialty, easy and simple to handle the precision is high, guarantees that the rivet is perpendicular with the part in arbitrary direction.
In order to realize above-mentioned purpose, design a straightness adjustment appurtenance that hangs down for rotatory self tapping riveting, including the connecting rod, its characterized in that: the top of the connecting rod is connected with the detection block, and the bottom of the connecting rod is connected with the pressure head; the detection block is in an arc panel structure, and a plurality of round holes are uniformly distributed at the upper part and the lower part of the detection block; the pressure head be spoon form structure, be located the middle part of pressure head and be equipped with convex recess, convex recess embeds is equipped with movable bobble.
The pressure head, the connecting rod and the detection block are of an integrated connection structure.
The round holes on the upper part and the lower part of the detection block are internally connected with small detection needles which are in needle-shaped cylinder structures.
The upper part of the connecting rod is a circular arc-shaped connecting rod, and the lower part of the connecting rod is a vertical connecting rod.
The pressure heads positioned around the circular arc-shaped groove are respectively provided with a positioning hole.
Compared with the prior art, the utility model, a hang down straightness adjustment appurtenance for rotatory self tapping riveting is provided, through the instrument of specialty, easy and simple to handle the precision high, guarantees that the rivet is perpendicular with the part in arbitrary direction.
The verticality precision of the FDS can be improved, the board head slipping frequency is reduced, the service life of the board head is prolonged, and the cost is reduced; the probability of the rivet slipping is reduced, and the service life of other spare parts such as the positioning copper guide sleeve is prolonged; the production efficiency is improved, and the generation of reworked products is reduced.

Referring to fig. 2, 1 is a pressure head, 2 is a connecting rod, 3 is a round hole, 4 is a detection small needle, and 5 is a detection block.
Detailed Description
The invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 to 4, the top of the connecting rod 2 is connected with the detection block 5, and the bottom of the connecting rod 2 is connected with the pressure head 1; the detection block 5 is in a circular arc panel structure, and a plurality of circular holes 3 are uniformly distributed at the upper part and the lower part of the detection block 5; the pressure head 1 be spoon form structure, be located the middle part of pressure head 1 and be equipped with convex recess, convex recess embeds is equipped with movable bobble.
The pressure head 1, the connecting rod 2 and the detection block 5 are of an integrated connection structure.
The round holes positioned at the upper part and the lower part of the detection block 5 are connected with small detection needles 4, and the small detection needles 4 are in needle-shaped cylindrical structures.
The upper part of the connecting rod 2 is a circular arc-shaped connecting rod, and the lower part of the connecting rod 2 is a vertical connecting rod.
The pressure heads 1 positioned around the arc-shaped groove are respectively provided with a positioning hole.
The FDS connecting device comprises a pressure head 1, a connecting rod 2 and a detection block 5, wherein the detection block 5 is provided with a round hole 3 for detecting the connection of a small needle 4. The pressure head 1 is provided with an arc-shaped groove, a movable small ball is arranged in the groove, and the pressure head 1 is completely attached to the spherical surface of the movable small ball when the riveter presses down, so that the pressure head 1 is completely and vertically attached to a part. Then, the detection small needle 4 is inserted into the round hole 3 on the detection block 5, and the verticality of the riveter is judged according to the depth of the detection small needle 4 inserted into the round hole 3.
The method comprises the following specific operations: the rivet nose of riveter is torn open, presses down and presses the air cylinder, and the riveter tightly pushes down the utility model discloses the movable bobble in the convex recess of the pressure head 1 of instrument makes the utility model discloses the instrument tightly pastes the part, then inserts through detecting little needle 4 and detect the straightness that hangs down that the degree of depth detected the riveter in the round hole 3 on the piece 5.
The traditional verticality teaching is realized by manual visual observation, and the precision of the verticality cannot be guaranteed. Novel straightness teaching that hangs down uses dedicated demonstrator instrument, and easy and simple to handle the precision height guarantees that the rivet is perpendicular with the part in arbitrary direction.
