[0021] An application of a flattening device for flattening the end of a throttle bolt, using the above-mentioned flattening device for flattening the end of a throttle bolt, the specific steps are as follows:

[0022] S1. The throttle body is placed on the positioning block, and the first positioning pin of the positioning block is embedded in the mounting hole of the throttle body. The scanner scans the QR code or barcode of the throttle body. Before the throttle bolt is flattened, the scanner feeds back the relevant information to the control mechanism after scanning. The control mechanism determines or checks whether the throttle body meets the requirements of a qualified product in the aforementioned process. If it does not meet the requirements, the control mechanism controls the alarm to sound an alarm. If it meets the requirements, the subsequent throttle bolt flattening operation is continued.

[0023] S2, the control mechanism controls the second driving mechanism to move the second mounting plate on the slide rail so that one of the throttle bolts is located directly above the lower pressure head;

[0024] S3, the control mechanism controls the first driving mechanism to move the upper pressure head downward, and when the upper pressure head contacts the top nut of the throttle bolt, the upper pressure head continues to move downward, and the throttle shaft and the throttle body also move downward synchronously and compress the spring until the upper pressure head and the lower pressure head press the throttle bolt tightly, and the throttle shaft and the throttle body stop moving downward. At this time, under the action of the spring, the throttle shaft always contacts the bottom of the nut of the throttle bolt, and the lower pressure head cooperates with the lower pressure head to continue to apply pressure to the throttle bolt until the end of the throttle bolt is flattened to form a flat portion;

[0025] S4, the control mechanism controls the first driving mechanism to move the upper pressure head upward, and under the action of the spring, the throttle shaft and the throttle body are lifted by the third mounting plate and the positioning block, and the throttle bolt with the flattened end leaves the lower pressure head, and the control mechanism controls the second driving mechanism to move the second mounting plate horizontally on the slide rail, so that the other throttle bolt is located directly above the lower pressure head, and after repeating step S3, the operation of flattening the ends of the two throttle bolts is completed;

[0026] S5. The control mechanism controls the first driving mechanism to move the upper pressure head upward. Under the action of the spring, the throttle shaft and the throttle body are lifted again by the third mounting plate and the positioning block. The other throttle bolt with the flattened end also leaves the lower pressure head, and the throttle body is removed from the positioning block.

[0027] Further, in step S3, the pressure sensor detects the pressure of the upper pressure head and feeds back to the control mechanism;

[0028] In step S3, the CCD camera collects images of the throttle body and feeds them back to the control mechanism, which stores them.

[0029] In view of the above technical features, the present invention has the following beneficial effects:

[0030] 1. A flattening device for flattening the end of a throttle bolt of the present invention applies pressure to the bolts for connecting the throttle plate and the throttle shaft through an upper pressure head and a lower pressure head, so as to flatten the end of the throttle bolt (i.e., the end of the bolt rod away from the nut). After flattening, a flat portion having an area larger than the cross-sectional area of ​​the screw rod is formed. The flat portion can effectively prevent the bolt from falling off the throttle shaft (such as the bolt hole on the throttle shaft that matches the bolt), thereby greatly improving the safety of the throttle body product.

[0031] 2. The flattening device of the present invention is used for flattening the end of a throttle bolt. In the process in which the upper pressure head and the lower pressure head apply pressure to the throttle bolt through the elastic buffer mechanism, the elastic buffer mechanism helps the throttle shaft and the throttle body to move downward adaptively, thereby protecting the throttle shaft and the throttle body from being crushed.

[0032] 3. The flattening device of the present invention is used for flattening the end of a throttle bolt. The flattening device moves the throttle body through a translation mechanism, so that the two bolts on the throttle shaft can be located between the upper pressure head and the lower pressure head in sequence, thereby completing the flattening operation of the throttle bolt.

[0033] 4. The flattening device for flattening the end of a throttle bolt of the present invention detects the pressure of the upper pressure head through a pressure sensor to avoid damaging the throttle shaft. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the appended claims of the application equally.

[0053] A flattening device for flattening the end of a throttle bolt, characterized in that: the flattening device comprises a frame 700, a workbench 600 is provided in the middle of the frame 700, a flattening device for flattening the end of a throttle bolt 103 and a scanner (not shown in the attached drawings) for scanning a two-dimensional code or a barcode of a throttle body 100 are provided on the workbench 600, the flattening device comprises a bottom plate 200, a vertical plate 204 is provided on the bottom plate 200, the vertical plate 204 is connected to a first driving mechanism 201, the movable end of the first driving mechanism 201 is connected to an upper pressure head 202, and the bottom plate 200 is also provided with a first fixing block 205, a lower pressure head 206 is provided on the top of the first fixing block 205, and the upper pressure head 202 and the lower pressure head 206 correspond to the upper and lower parts of the throttle bolt 103 respectively. The first driving mechanism 201 drives the upper pressure head 202 to move downward, and cooperates with the lower pressure head 206 to apply pressure to the throttle bolt 103, and flattens the end 104 of the throttle bolt (i.e., the end of the bolt rod away from the nut), and after flattening, a flat portion 105 with an area larger than the cross-sectional area of ​​the screw is formed. The flat portion 105 can effectively prevent the bolt from falling off the throttle shaft, greatly improving the safety of the throttle body 100 product. The throttle bolt 103 is used to connect and fix the throttle plate 102 with the throttle shaft 101.

[0054] The flattening device further comprises a supporting mechanism 300 for supporting the throttle body 100, the supporting mechanism 300 comprises a third mounting plate 301, a positioning block 302 is provided on the third mounting plate 301, a positioning inclined surface 303 for fixing the throttle body 100 is provided on the top of the positioning block 302; a first positioning pin 306 for embedding into the mounting hole of the throttle body 100 is provided on the positioning inclined surface 303. The throttle body 100 is placed on the positioning inclined surface 303, and the first positioning pin 306 is embedded in the mounting hole of the throttle body 100, ensuring that the throttle passage 106 is tilted upward (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, with the nut of the bolt on the top and the bolt end 104 at the bottom, so that the bolt will not fall out of the screw hole of the throttle shaft before being pressed. The positioning block 302 is detachably connected to the third mounting plate 301 , so that the positioning block 302 can be easily replaced.

[0055] The third mounting plate 301 may be indirectly connected to the first mounting plate 504 .

[0056] The positioning block 302 is provided with a first through hole 304 which passes through from top to bottom, and the third mounting plate 301 is provided with a third through hole 305 which passes through from top to bottom. The first through hole 304 and the third through hole 305 correspond in position, and the pressing head 206 is located in the first through hole 304 and the third through hole 305, so that the pressing head 206 can be embedded in the throttle channel 106 and aligned with the end 104 of the throttle bolt.

[0057] The third mounting plate 301 is provided with a second positioning pin 308 for fixing the positioning block 302. The second positioning pin 308 increases the position accuracy between the third mounting plate 301 and the positioning block 302 to avoid changes in the positions of the two. For example, the positioning block 302 moves on the third mounting plate 301, affecting the position correspondence between the first through hole 304 and the third through hole 305 in the vertical direction.

[0058] The flattening device also includes an elastic buffer mechanism 400, which includes an elastic member. A second mounting plate 501 is also provided below the third mounting plate 301. The third mounting plate 301 and the second mounting plate 501 are connected by an elastic member. The elastic member can support the throttle body 100 and provide pressure buffering for the throttle shaft and the throttle body 100. For example, when the upper pressure head 202 and the lower pressure head 206 press the throttle bolt 103, the throttle shaft moves downward with the throttle body 100 until the throttle bolt end 104 abuts against the lower pressure head 206, and the throttle bolt end 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 on the throttle shaft and the throttle body 100 to avoid bending the throttle shaft or damaging the throttle body 100. Moreover, during the process of the throttle bolt 103 being flattened, the elastic member can always ensure that the throttle shaft 101 is in contact with the nut of the throttle bolt 103, ensuring that the throttle bolt end 104 is always exposed outside the throttle shaft 101, so that the throttle bolt end 104 is subsequently flattened to form a flat portion 105.

[0059] Preferably, the third mounting plate 301 and the second mounting plate 501 are connected by four groups of elastic members evenly distributed to disperse the pressure of the third mounting plate 301 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 combined to adjust the total upward elastic force of the second mounting plate 501. The bottom of 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 includes a spring 401. 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, and 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 guide rod 307 to move downward. Each guide rod 307 passes through the guide hole 503 of the second mounting plate 501 and is connected to the corresponding bearing.

[0060] The second mounting plate 501 is provided with a second through hole 502 which passes through from top to bottom. The second through hole 502 corresponds to the first through hole 304 and the third through hole 305. The pressing head 206 is located in the second through hole 502, so that the pressing head 206 can be embedded in the throttle passage 106 and aligned with the end 104 of the throttle bolt.

[0061] The flattening device also includes a translation mechanism 500 and a first mounting plate 504 arranged on the bottom plate 200. The translation mechanism 500 includes a slide rail 505 arranged on the first mounting plate 504 and parallel to the throttle axis. The second mounting plate 501 is slidably connected to the slide rail 505 through a slider 506. A second fixing plate 510 is also provided on the first mounting plate 504 on one side of the slide rail 505. The second fixing plate 510 is provided with a second driving mechanism 513. The movable end of the second driving mechanism 513 is connected to the slide rail 505. The second mounting plate 501 is connected to the second driving mechanism 513, and the movable end of the second driving mechanism 513 brings the second mounting plate 501 to move along the slide rail 505, so as to help the two throttle bolts 103 to be located between the upper pressing head 202 and the lower pressing head 206, and complete the flattening operation of the two throttle bolt ends 104, and the moving process is also smoother; the first mounting plate 504 on the other side of the slide rail 505 is also provided with a first fixing plate 507, and the first fixing plate 507 is provided with a first stop portion 508 and a side surface of the first fixing plate 507 facing the slide rail 505. The first buffer 509, the first stop portion 508 and the first buffer 509 correspond to the second mounting plate 501. When the movable end of the second driving mechanism 513 extends out, before approaching the first fixed plate 507, the first buffer 509 abuts against the second mounting plate 501 to help the second mounting plate 501 to decelerate. The first stop portion 508 helps the second mounting plate 501 to stop moving to prevent the slider 506 of the second mounting plate 501 from separating from the slide rail 505. The second fixed 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 mounting plate 501. When the movable end of the second driving mechanism 513 retracts, before approaching the second fixed plate 510, the second buffer 512 abuts against the second mounting plate 501 to help the second mounting plate 501 to decelerate. The second stop portion 511 helps the second mounting plate 501 to stop moving to prevent the slider 506 of the second mounting plate 501 from separating from the slide rail 505.

[0062] The first mounting plate 504 is disposed on the bottom plate 200 , and the first fixing block 205 is fixed on the first mounting plate 504 .

[0063] Preferably, the flattening device includes a control mechanism, which controls the operation of the first drive mechanism 201 and the second drive mechanism 513; the movable end of the first drive mechanism 201 is also provided with a pressure sensor 203 for detecting the pressure condition of the upper pressure head 202, and the pressure sensor 203 feeds back the pressure condition of the upper pressure head 202 to the control mechanism, thereby realizing automatic operation of the flattening device for flattening the end of the throttle bolt. If the pressure of the upper pressure head 202 fed back by the pressure sensor 203 is too large, the control mechanism controls the first drive mechanism 201 to move upward to avoid damaging the throttle shaft.

[0064] The base plate 200 is fixed on the work table plate 600 .

[0065] Preferably, a CCD camera 701 is also provided on the frame 700 , and the CCD camera 701 is used to collect images of the throttle body 100 and feed back the collected image information to the control mechanism.

[0066] A waste collection trough 702 is also provided below the workbench 600 , and the waste collection trough 702 is fixed on the frame 700 .

[0067] An application of a flattening device for flattening the end of a throttle bolt, using the above-mentioned flattening device for flattening the end of a throttle bolt, the specific steps are as follows:

[0068] S1. The throttle body 100 is placed on the positioning block 302, and the first positioning pin of the positioning block 302 is embedded in the mounting hole of the throttle body 100. The scanner scans the QR code or barcode of the throttle body 100. Before the flattening operation of the throttle bolt 103, the scanner feeds back the relevant information to the control mechanism after scanning, and the control mechanism judges or checks whether the throttle body 100 meets the requirements of a qualified product in the aforementioned process. If it does not meet the requirements, the control mechanism controls the alarm to sound an alarm. If it meets the requirements, the subsequent flattening operation of the throttle bolt 103 is continued;

[0069] S2, the control mechanism controls the second driving mechanism to move the second mounting plate 501 on the slide rail so that one of the throttle bolts 103 is located directly above the lower pressure head 206;

[0070] S3, the control mechanism controls the first driving mechanism 201 to move the upper pressure head 202 downward. When the upper pressure head 202 abuts against the top nut of the throttle bolt 103, the upper pressure head 202 continues to move downward, and the throttle shaft 101 and the throttle body 100 also move downward synchronously and compress the spring 401 until the upper pressure head 202 and the lower pressure head 206 press the throttle bolt 103 tightly, and the throttle shaft 101 and the throttle body 100 stop moving downward. At this time, under the action of the spring 401, the throttle shaft 101 always abuts against the bottom of the nut of the throttle bolt 103, ensuring that the end of the throttle bolt 103 is always exposed outside the throttle shaft 101, so that the end of the throttle bolt 103 is subsequently flattened to form a flat portion 105, and the lower pressure head 206 cooperates with the lower pressure head 206 to continue to apply pressure to the throttle bolt 103 until the end of the throttle bolt 103 is flattened to form a flat portion 105;

[0071] In step S3, the pressure sensor 203 detects the pressure of the upper pressure head 202 and feeds back to the control mechanism;

[0072] In step S3, the CCD camera 701 collects images of the throttle body 100 and feeds the images back to the control mechanism, which stores the images.

[0073] S4, the control mechanism controls the first driving mechanism 201 to move the upper pressure head 202 upward, and under the action of the spring 401, the throttle shaft 101 and the throttle body 100 are lifted by the third mounting plate 301 and the positioning block 302, and the throttle bolt 103 with the flattened end leaves the lower pressure head 206, and the control mechanism controls the second driving mechanism to move the second mounting plate 501 on the slide rail, so that the other throttle bolt 103 is located directly above the lower pressure head 206, and after repeating step S3, the operation of flattening the ends of the two throttle bolts 103 is completed;

[0074] S5. The control mechanism controls the first driving mechanism 201 to move the upper pressure head 202 upward. Under the action of the spring 401, the throttle shaft 101 and the throttle body 100 are lifted again by the third mounting plate 301 and the positioning block 302. The other throttle bolt 103 with the flattened end also leaves the lower pressure head 206, and the throttle body 100 is removed from the positioning block 302.

9. Application of a flattening device for flattening the end of a throttle bolt, using the flattening device for flattening the end of a throttle bolt as claimed in claim 8, the specific steps are as follows: S1. The throttle body (100) is placed on the positioning block (302), and the first positioning pin (306) of the positioning block (302) is embedded in the mounting hole of the throttle body (100). A scanner scans the two-dimensional code or bar code of the throttle body (100). Before the flattening operation of the throttle bolt (103), the scanner feeds back relevant information to the control mechanism after scanning. The control mechanism determines or checks whether the throttle body meets the requirements of being a qualified product in the aforementioned process. If it is not a qualified product, the control mechanism controls the alarm to sound an alarm. If it is a qualified product, the subsequent throttle bolt flattening operation is continued. S2, the control mechanism controls the second driving mechanism (513) to move the second mounting plate (501) on the slide rail (505) in a horizontal direction, so that one of the throttle bolts (103) is located directly above the lower pressure head (202); S3, the control mechanism controls the first driving mechanism (201) to move the upper pressure head (202) downward, and when the upper pressure head (202) contacts the top nut of the throttle bolt (103), the upper pressure head (202) continues to move downward, and the throttle shaft (101) and the throttle body (100) also move downward synchronously and compress the spring (401) until the upper pressure head (202) and the lower pressure head (206) press the throttle bolt (103), and the throttle shaft (101) and the throttle body (100) stop moving downward. At this time, under the action of the spring (401), the throttle shaft (101) always contacts the bottom of the nut of the throttle bolt (103), and the lower pressure head (206) cooperates with the lower pressure head (202) to continue to apply pressure to the throttle bolt (103) until the end (104) of the throttle bolt is flattened to form a flat portion (105); S4, the control mechanism controls the first driving mechanism (201) to move the upper pressure head (202) upward, and under the action of the spring (401), the throttle shaft (101) and the throttle body (100) are lifted by the third mounting plate (301) and the positioning block (302), and the throttle bolt (103) with the flattened end leaves the lower pressure head (206), and the control mechanism controls the second driving mechanism (513) to move the second mounting plate (501) on the slide rail (505) in a horizontal direction, so that the other throttle bolt (103) is located directly above the lower pressure head (206), and after repeating step S3, the operation of flattening the ends of the two throttle bolts is completed; S5. The control mechanism controls the first driving mechanism (201) to move the upper pressure head (202) upward. Under the action of the spring (401), the throttle shaft (101) and the throttle body (100) are lifted again by the third mounting plate (301) and the positioning block (302). The other throttle bolt (103) with the flattened end also leaves the lower pressure head (206), and the throttle body (100) is removed from the positioning block (302).
