[0032] Above the lower positioning surface 302, there is a vertically movable riveting head 100. When the riveting portion 403 is placed on the lower positioning surface 302 and the pole column 500 is embedded in the pole column groove 303, the reference plate 300 and the positioning plate 200 clamp the housing 400 in opposite directions so that the housing 400 is fixed in a stationary state. The riveting head 100 presses the pole column 500 downward to rivet and fix the pole column 500 to the housing 400.

[0033] For the above-provided pole column and housing riveting device, the lower positioning surface 302 and the pole column groove 303 are arranged on the reference plate 300.

[0035] The rotating structure 201 can be a bolt or the like. By rotating the rotating structure 201, the positioning plate 200 can move towards or away from the reference plate 300. When the positioning plate 200 moves towards the reference plate 300, the positioning plate 200 and the reference plate 300 clamp and fix the housing 400 facing each other. When the positioning plate 200 moves away from the reference plate 300, the positioning plate 200 and the reference plate 300 release the clamped and fixed housing 400.

[0036] In this embodiment, there is a clamping interval between the positioning plate 200 and the reference plate 300. The side of the riveting portion 403 extends outward to form a lower positioning wall 402. When the riveting portion 403 is placed on the lower positioning surface 302 and the pole column 500 is embedded in the pole column groove 303, the lower positioning wall 402 is placed in the clamping interval.

[0037] After the lower positioning wall 402 is embedded in the clamping interval, the rotating structure 201 rotates, causing the positioning plate 200 to move towards the reference plate 300, and the positioning plate 200 and the reference plate 300 clamp and fix the housing 400 facing each other. When it is necessary to disengage the lower positioning wall 402 from the clamping interval, the rotating structure 201 can be rotated to cause the positioning plate 200 to move away from the reference plate 300, increasing the clamping interval.

[0038] In this embodiment, a positioning groove 301 is formed on the reference plate 300.

The housing 400 has a positioning section 401, and the riveting portion 403 is formed at the bottom of the positioning section 401. When the riveting portion 403 is placed on the lower positioning surface 302, the positioning section 401 is embedded in the positioning groove 301, and both sides of the positioning section 401 are laterally abutted against the side walls of the positioning groove 301.

[0039] By forming the positioning groove 301, the entire positioning section 401 is embedded in the positioning groove 301, the riveting portion 403 abuts against the lower positioning surface 302, the positioning section 401 is embedded in the positioning groove 301, and both sides of the positioning section 401 are laterally abutted against the side walls of the positioning groove 301, realizing the positioning of the bottom and both sides of the positioning section 401, so that the positioning of the housing 400 is more stable.

[0040] In this embodiment, the top of the reference plate 300 has an upper positioning surface 305, and the upper positioning surface 305 is arranged adjacent to the top opening; the housing 400 has a positioning step 404 arranged downward, and the positioning step 404 is arranged adjacent to the positioning section 401; when the riveting part 403 is placed on the lower positioning surface 302, the positioning step 404 abuts against the upper positioning surface 305 from top to bottom.

[0042] In this embodiment, the positioning plate 200 has a hollow area 202 for the riveting head 100 to penetrate, and the hollow area 202 is arranged opposite to the positioning groove 301. In this way, after the positioning plate 200 and the reference plate 300 clamp the housing 400 for positioning and fixing, the riveting head 100 penetrates into the hollow area 202 from top to bottom, and by entering the positioning groove 301, the pole 500 is riveted, avoiding interference during the movement of the riveting head 100.

[0043] In this embodiment, the positioning plate 200 has a side pressing part 203, the reference plate 300 has a side pressing surface 304 facing the side pressing part 203, and the above-mentioned clamping interval is formed between the side pressing surface 304 and the side pressing part 203; the side part of the positioning step 404 extends downward with an upper positioning wall 405. When the positioning step 404 abuts against the upper positioning surface 305 from top to bottom, the upper positioning wall 405 is placed in the clamping interval.

When the positioning plate 200 moves relative to the reference plate 300, the positioning pin 306 moves relative to the guiding hole 206. Through the movable cooperation between the positioning pin 306 and the guiding hole 206, the movement of the positioning plate 200 relative to the reference plate 300 can be positioned and guided, avoiding the phenomenon of misaligned movement.

[0047] In this embodiment, the reference plate 300 is provided with mounting holes, which are arranged directly opposite to the guiding holes 206. The inner end of the positioning pin 306 is movably placed in the mounting hole to form an inner movable section 3061.

The elastic ring 3065 is circumferentially extruded in the guiding hole 206 and is in a compressed deformation state.

[0050] During the process of the positioning plate 200 moving towards or away from the reference plate 300, the positioning pin 306 moves relative to the positioning plate 200 and the reference plate 300 respectively. The inner elastic column 3063 elastically deforms axially, and the elastic ring 3065 rolls along the width of the annular groove 3064.

[0051] In this way, when the positioning plate 200 moves towards or away from the reference plate 300, the outer movable section 3062 is used to guide the movement of the positioning plate 200. Moreover, the inner movable section 3061 is movably connected to the mounting hole of the reference plate 300 through the inner elastic column 3063. The outer movable section 3062 is movably inserted into the guiding hole 206 and has a plurality of elastic rings 3065 in rolling fit, so that the whole positioning pin 306 is in an axially elastic state, and the outer movable section 3062 is in a circumferentially elastic state, which can prevent the outer movable section 3062 from being stuck in the guiding hole 206.

[0052] During the process of the positioning plate 200 moving relative to the reference plate 300, the positioning pin 306 has an automatic elastic adjustment function in the axial and circumferential directions. Moreover, when the relative position between the positioning plate 200 and the reference plate 300 is fixed, the elastic adjustment function can automatically reset, so as to realize elastic adjustment during the movement process, and has an elastic reset and fixing function in the fixed state.
