To achieve these goals, the technical scheme taked of the utility model is:
Shape tube riveting joint provided by the utility model, described shape tube is the structure that has corner, described riveting joint comprises the forcing press joint, described riveting joint is established locating piece, described locating piece is fixed on the described forcing press joint, described riveting joint is established two clamps that are used to clamp described shape tube, and described clamp is installed on the described locating piece by the clamp rotating shaft; Establish stage clip between described two clamps.
Establish the locating slot of the end location that is used for described shape tube on the described locating piece.
Described riveting joint is provided with jacking block, is provided with the dish spring between described jacking block and described forcing press joint.
Be provided with elasticity in the described locating slot and bump pearl.
A spacer pin is respectively established in two outsides of described two clamps, and described spacer pin is fixedly mounted on the described locating piece.
The utility model adopts technique scheme, and the use spring mechanism is controlled the clamping of clamp and opened, and is simple in structure; At shape tube Center of Pressure tail end the dish spring of some is housed, had both guaranteed to bear enough big riveting power, can absorb the slight pressure stroke after riveting puts in place again; Bump the angle orientation that pearl had both been satisfied shape tube by locating slot and elasticity, leave the suitable space of riveting process again.
Description of drawings
Below expressed content of each width of cloth accompanying drawing of this specification and the mark among the figure are briefly explained:
Fig. 1 is the schematic top plan view of structure shown in Figure 2;
Fig. 2 is a structural representation of the present utility model.
Be labeled as among the figure:
1, forcing press joint, 2, locating piece, 3, clamp, 4, clamp, 5, jacking block, 6, the clamp rotating shaft, 7, elasticity bumps pearl, 8, spacer pin, 9, the dish spring, 10, stage clip, 11, shape tube, 12, locating slot.
The specific embodiment
Contrast accompanying drawing below, by description to embodiment, to effect and operation principle, the manufacturing process of the mutual alignment between the shape of the specific embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present utility model, technical scheme had more complete, accurate and deep understanding to help those skilled in the art.
The of the present utility model structure expressed as Fig. 1, Fig. 2, the utility model is a kind of shape tube riveting joint, described shape tube 11 is for having the structure of corner, and described riveting joint comprises forcing press joint 1, and described forcing press joint 1 is fastenedly connected by its installing handle and forcing press.
In order to solve the problem that exists at the described present known technology of this specification background technology part and to overcome its defective, realize the goal of the invention that press-fit of shape tube in the cavity part, the technical scheme that the utility model is taked is:
Shape tube riveting joint provided by the utility model is established locating piece 2, described locating piece 2 is fixed on the described forcing press joint 1, described riveting joint is established clamp 3, the clamp 4 that is used to clamp described shape tube 11, and described clamp 3, clamp 4 are installed on the described locating piece 2 by clamp rotating shaft 6; Establish stage clip 10 between described clamp 3, the clamp 4.The effect of stage clip 10 is to make clamp 3, clamp 4 play the effect of clamping.
The utility model adopts spring mechanism control to clamp and opens, and clamp mechanism is effectively clamped shape tube 11, and is simple in structure, easy to operate.
Establish the locating slot 12 of the end location that is used for described shape tube 11 on the locating piece 2 described in the utility model.
Be provided with elasticity in the described locating slot 12 and bump pearl 7.
By the effect that locating slot 12 and elasticity are bumped pearl 7, both satisfied the angle orientation of shape tube 11, leave the suitable space of riveting process again.
Riveting joint described in the utility model is provided with jacking block 5, is provided with dish spring 9 between described jacking block 5 and described forcing press joint 1.
At the Center of Pressure of shape tube 11 tail end the dish spring 9 of some is housed, had both guaranteed to bear enough big riveting power, can absorb the slight pressure stroke after riveting puts in place again;
A spacer pin 8 is respectively established in two outsides of clamp 3 described in the utility model, clamp 4, and described spacer pin 8 is fixedly mounted on the described locating piece 2.When clamp 3, clamp 4 shrink too smallly under the effect of stage clip 10, make shape tube 11 can't inject clamped position between clamp 3, the clamp 4, at this moment, two spacer pins 8 just can make it keep certain stretching degree until the effect that stops.
Using method of the present utility model:
As the manual holes for clamping of the tail end of shape tube 11 being aimed at riveter joint 1, and the tilting section of shape tube 11 is aimed at locating slot 12 holders go into to put in place, at this moment the clamp 4 on the clamp 3 on the left side and the right will be under the elastic force effect of stage clip 10, around clamp rotating shaft 6 rotations, the end that stage clip 10 is installed opens, and the other end of clamp 3 and clamp 4 is with shape tube 11 clampings and hold tightly.
The effect of spacer pin 8 is when clamping shape tube 11 not, and restriction clamp 3 and clamp 4 are under the effect of stage clip 10, and its pinching end is unlikely to close up fully.
In this process, two clamp rotating shafts 6 are respectively the pivot of clamp 3 and clamp 4.
Two spacer pins 8 guarantee shape tube 11 is clamped in the design centre.
When forcing press is worked, shape tube 11 progressively is pressed into the air throttle cavity.
When shape tube 11 rivetings put in place, when forcing press continued micro-stroke, shape tube 11 tail ends passed to dish spring 9 by its absorption by jacking block 5 with pressure.Can bear maximum riveting power when the design of dish spring 9 should be able to be satisfied operate as normal, absorb unnecessary pressure when crossing stroke.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or design of the present utility model and technical scheme are directly applied to other occasion without improving, all within protection domain of the present utility model.
