[0040] Reference Figures 1 to 9, specific embodiment 1, the embodiment 1 provides a flattening device for the end flattening of a throttle bolt, comprising a bottom plate 200, the bottom plate 200 is provided with a vertical plate 204, the vertical plate 204 is connected with a first driving mechanism 201, the movable end of the first driving mechanism 201 is connected with an upper pressing head 202, the bottom plate 200 is also provided with a first fixed block 205, the top of the first fixed block 205 is provided with a lower pressing head 206, the upper pressing head 202 and the lower pressing head 206 correspond to the upper and lower sides of the throttle bolt 103 respectively, the first driving mechanism 201 drives the lower movement of the upper pressing head 202, cooperates with the lower pressing head 206 to exert pressure on the throttle bolt 103, the end 104 (i.e. the end of the bolt rod far away from the nut) of the throttle bolt is flattened, after flattening, a flat part 105 with an area larger than the cross-sectional area of the screw rod is formed, the flat part 105 can effectively prevent the bolt from falling off from the throttle shaft, and the safety of the throttle body 100 product is greatly improved. The throttle bolt 103 is used for connecting and fixing the throttle blade 102 with the throttle shaft 101.

[0041] The flattening device also comprises a supporting mechanism 300 for supporting the throttle body 100, the supporting mechanism 300 comprises a third mounting plate 301, the third mounting plate 301 is provided with a positioning block 302, the top of the positioning block 302 is provided with a positioning inclined surface 303 for fixing the throttle body 100, and the positioning inclined surface 303 is provided with a first positioning pin 306 embedded in the mounting hole of the throttle body 100. The throttle body 100 is placed on the positioning inclined surface 303, the first positioning pin 306 is embedded in the mounting hole of the throttle body 100, the throttle passage 106 is ensured to be in an inclined state (at this time, the throttle passage 106 is perpendicular to the positioning inclined surface 303 of the positioning block 302), and the bolt on the throttle shaft is in a vertical state, the nut of the bolt is on the upper side, and the end 104 of the bolt is on the lower side, so that the bolt cannot fall out of the screw hole of the throttle shaft before being pressed. The positioning block 302 and the third mounting plate 301 are detachably connected, so that the positioning block 302 can be replaced conveniently.

[0042] The third mounting plate 301 can be indirectly connected with the first mounting plate 504.

[0043] The positioning block 302 is provided with a first through hole 304 penetrating through the upper and lower sides, the third mounting plate 301 is provided with a third through hole 305 penetrating through the upper and lower sides, the first through hole 304 and the third through hole 305 are in position correspondence, and the lower pressing head 206 is located in the first through hole 304 and the third through hole 305, so that the lower pressing head 206 can be embedded in the throttle passage 106 and aligned with the end 104 of the throttle bolt.

[0044] The third mounting plate 301 is provided with a second positioning pin 308 for fixing the positioning block 302, and the second positioning pin 308 increases the positional accuracy between the third mounting plate 301 and the positioning block 302, so as to avoid the positional change of the two, such as the movement of the positioning block 302 on the third mounting plate 301, which affects the positional correspondence in the vertical direction of the first through hole 304 and the third through hole 305.

[0045] The flattening device also comprises an elastic buffering mechanism 400, which comprises an elastic member. The third mounting plate 301 is further provided with a second mounting plate 501 below, and the third mounting plate 301 and the second mounting plate 501 are connected through the elastic member. The elastic member can support the throttle body 100 and also provide pressure buffering for the throttle shaft and the throttle body 100. For example, during the process of pressing the throttle bolt 103 by the upper pressing head 202 and the lower pressing head 206, the throttle shaft with the throttle body 100 moves downward until the throttle bolt end portion 104 abuts against the lower pressing head 206, and then the throttle bolt end portion 104 is flattened. The throttle body 100 compresses the elastic member through the positioning block 302 and the third mounting plate 301, the elastic member buffers the pressure received by the throttle shaft and the throttle body 100, and avoids the bending of the throttle shaft or the damage of the throttle body 100. Moreover, during the flattening process of the throttle bolt 103, the elastic member can always ensure that the throttle shaft 101 abuts against the nut of the throttle bolt 103, and ensure that the throttle bolt end portion 104 is always exposed outside the throttle shaft 101, which is convenient for the subsequent flattening of the throttle bolt end portion 104 to form the flat portion 105.

[0046] Preferably, the third mounting plate 301 and the second mounting plate 501 are connected through four groups of uniformly distributed elastic members, which dispersively distribute the pressure of the third mounting plate on the second mounting plate 501. The elastic forces of the four groups of elastic members (such as four groups of springs) can be the same or different, and the elastic forces are superimposed on each other to adjust the total upward elastic force of the second mounting plate 501 as a whole. The third mounting plate 301 is provided with four guide rods 307, and the second mounting plate 501 is provided with four guide holes 503. Each group of elastic members comprises a spring 401, and the corresponding guide rod 307 is inserted into the corresponding guide hole 503 after being embedded in the inner circle of the spring 401. When the third mounting plate 301 moves downward, the spring 401 is compressed, the spring 401 is compressed along the corresponding guide rod 307, and the corresponding guide rod 307 moves downward along the corresponding guide hole 503. The space between the second mounting plate 501 and the first mounting plate 504 provides space for the downward movement of the guide rod 307. Each guide rod 307 is connected to a corresponding bearing after passing through the guide hole 503 of the second mounting plate 501.

[0047] The second installation plate 501 is provided with a second through hole 502 which is vertically through the second installation plate 501 and corresponds to the first through hole 304 and the third through hole 305 in position. The lower pressing head 206 is located in the second through hole 502, so as to facilitate the lower pressing head 206 to be embedded in the throttle passage 106 and to be aligned with the throttle bolt end portion 104.

[0048] The flattening device further comprises a translation mechanism 500 and a first installation plate 504 provided on the bottom plate 200. The translation mechanism 500 comprises a slide rail 505 provided on the first installation plate 504 and parallel to the direction of the throttle shaft. The second installation plate 501 is slidably connected to the slide rail 505 through a slide block 506. The first installation plate 504 on one side of the slide rail 505 is further provided with a second fixing plate 510. The second fixing plate 510 is provided with a second driving mechanism 513. The second driving mechanism 513 is connected to the second installation plate 501 at the movable end. The movable end of the second driving mechanism 513 carries the second installation plate 501 to translate along the slide rail 505, so that both of the throttle bolts 103 can be located between the upper pressing head 202 and the lower pressing head 206, and the flattening operation of the two throttle bolt end portions 104 can be completed. The moving process is also more stable. The first installation plate 504 on the other side of the slide rail 505 is further provided with a first fixing plate 507. The first fixing plate 507 is provided with a first stop portion 508 and a first buffer 509 on the side facing the slide rail 505. The first stop portion 508 and the first buffer 509 correspond to the second installation plate 501. When the movable end of the second driving mechanism 513 is about to approach the first fixing plate 507, the first buffer 509 abuts against the second installation plate 501, so as to help the second installation plate 501 to slow down. The first stop portion 508 helps the second installation plate 501 to stop moving, so as to avoid the slide block 506 of the second installation plate 501 from being separated from the slide rail 505. The second fixing plate 510 is provided with a second stop portion 511 and a second buffer 512 on the side facing the slide rail 505. The second stop portion 511 and the second buffer 512 correspond to the second installation plate 501. When the movable end of the second driving mechanism 513 is about to retract, the second buffer 512 abuts against the second installation plate 501, so as to help the second installation plate 501 to slow down. The second stop portion 511 helps the second installation plate 501 to stop moving, so as to avoid the slide block 506 of the second installation plate 501 from being separated from the slide rail 505.

[0049] The first installation plate 504 is provided on the bottom plate 200. The first fixing block 205 is fixed on the first installation plate 504.

[0050] Preferably, the flattening device comprises a control mechanism, which controls the operation of the first driving mechanism 201 and the second driving mechanism 513; the active end of the first driving mechanism 201 is further provided with a pressure sensor 203 for detecting the pressure condition of the upper pressing head 202, and the pressure sensor 203 feeds back the pressure condition of the upper pressing head 202 to the control mechanism, so as to realize automatic operation of the flattening device for the end flattening of the throttle bolt, and if the pressure of the upper pressing head 202 fed back by the pressure sensor 203 is too large, the control mechanism controls the first driving mechanism 201 to move upward, so as to avoid damaging the throttle shaft.

[0051] The bottom plate 200 is fixed on the workbench plate 600.
