DETAILED DESCRIPTION

[0078] 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.

[0079] See also Figures 1 to 18 , Specific embodiment 1, this embodiment 1 provides a welding device for a throttle shaft, including a fixed angle device for adjusting the circumferential angle of the throttle shaft 101, a welding mechanism 500 and a control mechanism for welding the throttle shaft 101 and the reset gear assembly 105, and the control mechanism controls the operation of the fixed angle device and the welding mechanism 500.

[0080] The angle fixing device includes a first driving mechanism 301, an upper pressure head 302, a first base plate 206, a second base plate 210, a lower pressure head 201 and an elastic member 205. The second base plate 210 is located below the first base plate 206. The first base plate 206 is provided with a first through hole 207. The bottom of the lower pressure head 201 and the second base plate 210 are connected by the elastic member 205. The elastic member 205 (such as a spring) is located in the first through hole 207.

[0081] The first driving mechanism 301 (such as a cylinder) drives the upper pressure head 302 to press the throttle body 100 placed on the top of the first bottom plate 206, and the first bottom plate 206 and the upper pressure head 302 press and fix the throttle body 100. The lower pressure head 201 is embedded in the throttle passage 103, and the inclined surface 202 of the pressure head 201 presses the throttle plate 102 on the throttle shaft 101 from bottom to top under the action of the elastic member 205. At this time, the force of the lower pressure head 201 on the throttle plate 102 is controllable and elastic, and the throttle shaft 101 will not be bent, so that the circumferential rotation of the throttle shaft 101 is realized, and the angle of the throttle shaft 101 is adjusted without damaging the throttle shaft 101.

[0082] A slope 202 is provided on the top of the lower pressure head 201, and the slope 202 corresponds to the throttle plate 102 of the throttle body 100. The slope 202 is used to flip the throttle plate 102. The flipping of the throttle plate 102 simultaneously drives the circumferential rotation of the throttle shaft 101, thereby adjusting the angle of the throttle shaft 101 until the throttle plate 102 fits with the slope 202. At this time, the circumferential rotation angle of the throttle shaft 101 reaches a specified angle (i.e., the angle at which the throttle shaft 101 can be welded with the reset gear assembly 105), which facilitates the subsequent welding of the throttle shaft 101 with the reset gear assembly 105, and the welding angle is accurate. A groove 203 is provided in the middle of the inclined surface 202, and the groove 203 corresponds to the throttle shaft 101 of the throttle body 100, that is, the throttle shaft 101 is embedded in the groove 203, and the inclined surfaces 202 of the lower pressure head 201 on both sides of the groove 203 respectively fit the throttle plates 102 on both sides of the throttle shaft 101, ensuring that the throttle plates 102 can fit the inclined surfaces 202 of the lower pressure head, ensuring that the inclined surfaces 202 of the lower pressure head 201 can adjust the angle of the throttle shaft 101 more accurately, thereby realizing the precise angle setting function of the throttle shaft 101.

[0083] A third bottom plate 212 is also provided below the second bottom plate 210. The second bottom plate 210 and the third bottom plate 212 are connected by a support pad 213. The second bottom plate 210 is provided with a second guide hole 211 that runs through from top to bottom. A second guide rod 204 is provided at the bottom of the lower pressure head 201. The second guide rod 204 is located in the first through hole 207 and moves up and down in the second guide hole 211. A space is formed between the second bottom plate 210 and the third bottom plate 212 to facilitate the movement of the second guide rod 204. The design of the second guide rod 204 and the second guide hole 211 is to ensure that the lower pressure head 201 maintains vertical movement under the action of the elastic member 205, and the force pressing on the throttle plate 102 always remains vertically upward, ensuring the accuracy of the lower pressure head 201's function of setting the angle of the throttle shaft 101. In this embodiment 1, two second guide rods 204 are provided, corresponding to the two sides of the elastic member 205, respectively, so that the guiding effect is more stable.

[0084] The angle setting device also includes a first fixed plate 303, the third base plate 212 is fixed on the first fixed plate 303, the first fixed plate 303 is also provided with a plurality of support columns 304, the top of the support column 304 is connected to the first mounting plate 305, the first mounting plate 305 fixes the first driving mechanism 301, the movable end of the first driving mechanism 301 is connected to the first connecting plate 306, the bottom of the first connecting plate 306 is connected to the upper pressure head 302, and the upper pressure head 302 corresponds to the mounting hole 104 of the throttle body 100.

[0085] The upper end of the upper pressing head 302 passes through the first mounting hole 308 of the first connecting plate 306 and is fixed by the first fixing block 307 . The height of the upper pressing head 302 can be adjusted, and it is suitable for pressing and fixing throttle bodies 100 of different models.

[0086] At least three first padding blocks 208 for supporting the throttle body 100 are provided on the first base plate 206, wherein the tops of two first padding blocks 208 are provided with first positioning pins 209 for embedding into the mounting holes 104 of the throttle body 100. For example, the throttle body 100 is placed on the first padding blocks 208, wherein the two first positioning pins 209 are respectively embedded into two mounting holes 104 of the throttle body 104 (such as two mounting holes 104 at opposite corners), and the heights of the three first padding blocks 208 can be adjusted to ensure that the central axis of the channel of the throttle body 100 is in a vertical state, and the axis of the throttle shaft 101 is in a horizontal state. Preferably, the upper pressure head 302 and two of the first cushion blocks 208 are located on the same side of the throttle body 100, and the throttle body 100 is kept pressed and fixed in a relatively vertical direction as much as possible to avoid dispersing pressure and damaging the throttle body 100 or causing the throttle body 100 to tilt after being pressed; at the same time, such a design can also effectively prevent the throttle body 100 from being installed upside down, thereby playing an error-prevention function.

[0087] The lower pressure head 201 is cylindrical in shape, and the shape of the lower pressure head 201 matches that of the throttle channel 103, which not only ensures that the lower pressure head 201 can be embedded in the throttle channel 103, but also maximizes the area of ​​the inclined surface 202 on the top of the lower pressure head 201, helps to more accurately adjust the flip angle of the throttle plate 102, helps to adjust the circumferential rotation angle of the throttle shaft 101, and more accurately realizes the fixed angle function of the throttle shaft 101.

[0088] The angle determination device also includes a detection mechanism for detecting the position of the throttle plate 102, the detection mechanism includes a first laser measuring head 318 and a second laser measuring head 319 for detecting the position of the throttle plate 102, the height difference between the bottom end of the first laser measuring head 318 and the bottom end of the second laser measuring head 319 matches the inclined surface 202 of the lower pressure head 201, that is, the inclined angle of the corresponding straight line between the bottom end of the first laser measuring head 318 and the bottom end of the second laser measuring head 319 is the same as the inclined angle of the top inclined surface 202 of the lower pressure head 201, for example, the first laser measuring head 31 8 corresponds to one side area of ​​the throttle plate 102 (the higher side), and the bottom end of the second laser measuring head 319 corresponds to the other side area of ​​the throttle plate 102 (the lower side). As long as the bottom end of the first laser measuring head 318 can detect the one side area of ​​the throttle plate 102 and the bottom end of the second laser measuring head 319 can detect the other side area of ​​the throttle plate 102, it can be determined that the throttle plate 102 is flipped to the specified position. At this time, the circumferential angle of the throttle shaft 101 is also adjusted to the specified angle, which is convenient for the subsequent precise welding between the throttle shaft 101 and the reset gear assembly 105.

[0089] The projection of the straight line where the first laser measuring head 318 and the second laser measuring head 319 are located is perpendicular to the projection of the throttle shaft 101 , so as to ensure the accuracy of the first laser measuring head 318 and the second laser measuring head 319 in calculating the flip angle of the throttle plate 102 by detecting the position information of the throttle plate 102 .

[0090] The first connecting plate 306 is further provided with two second mounting holes 309, through which the first laser measuring head 318 and the second laser measuring head 319 are respectively passed through the two second mounting holes 309 and clamped by two clamping blocks 310, so that the heights of the first laser measuring head 318 and the second laser measuring head 319 can be adjusted through the clamping blocks 310, or the heights of the first laser measuring head 318 and the second laser measuring head 319 can also be adjusted separately, so as to match throttle bodies 100 of different specifications or meet the angle setting requirements of throttle shafts 101 of different inclination angles.

[0091] The tops of the two clamping blocks 310 are connected to the first connecting block 311, and the two ends of the first connecting block 311 are respectively connected to a first guide rod 312. The first guide rod 312 passes through the first guide hole 313 on the first connecting plate 306 and is locked by the locking limit block 314, ultimately to ensure that the first laser measuring head 318 and the second laser measuring head 319 can move vertically up and down.

[0092] A pressing block 315 is further provided at the bottom of the first connecting block 311. A third guide hole 316 is provided at the position of the pressing block 315 corresponding to the first guide block, and the first guide rod 312 passes through the third guide hole 316. Side grooves 317 are further provided on both sides of the pressing block 315, which are respectively embedded in the first laser measuring head 318 and the second laser measuring head 319. The pressing block 315 is used for the installation and positioning of the first laser measuring head 318 and the second laser measuring head 319 to increase stability.

[0093] The steps for using the angle-fixing device are as follows: first, the mounting hole 104 of the throttle body 100 is aligned with the first positioning pin 209 and then placed on the three first pad blocks 208; the lower pressure head 201 is synchronously embedded in the throttle channel 103 and corresponds to the throttle plate 102 to adjust the angle of the throttle shaft 101; the control mechanism controls the first driving mechanism 301 to drive the first connecting plate 306 to move downward, the upper pressure head 302 presses the throttle body 100, the first laser measuring head 318 and the second laser measuring head 319 are synchronously moved downward to detect the position of the throttle plate 102, and the relevant information is fed back to the control mechanism (such as PLC), and the control mechanism determines whether the position of the throttle plate 102 is accurate, and then determines whether the angle of the throttle shaft 101 is accurate.

[0094] The welding device further includes a workbench 700 , and the first fixing plate 303 is fixed on the workbench 700 .

[0095] The welding equipment also includes a limiting mechanism 400 for limiting the reset gear assembly 105, the limiting mechanism 400 includes a fourth bottom plate 401, a first slide rail 402 is provided on the fourth bottom plate 401, a second fixed block 404 can be slidably connected to the first slide rail 402 through a first slider 403, a first vertical plate 405 is provided on the second fixed block 404, and the first vertical plate 405 is provided with a vertical second driving mechanism 407 (such as a second cylinder, the movable end of the second cylinder moves up and down in the vertical direction), the movable end of the second driving mechanism 407 is connected to the first limiting rod 408, and the second fixed plate 501 moves forward and backward along the slide rail with the first limiting rod 408, so as to approach or move away from the reset gear assembly 105, the first limiting rod 408 is moved up and down by the second driving mechanism 407. When the first limiting rod 408 is against the reset gear assembly 105 (such as the gear of the reset gear assembly 105), the reset gear assembly 105 is fixed at a specified position. The so-called specified position refers to the reset gear assembly 105 rotating to a corresponding angle, which can meet the angle and position for welding with the throttle shaft 101. At this time, if the angle and position of the reset gear assembly 105 are not fixed by the first limiting rod 408, the reset gear assembly 105 will rotate to other positions under the action of the reset spring 106, and other positions cannot be used for the welding operation between the reset gear assembly 105 and the throttle shaft 101.

[0096] The second fixing block 404 is also provided with a stop bolt 410, which is threadedly connected to the second fixing block 404, and the bottom of the stop bolt 410 corresponds to the top surface of the fourth bottom plate 401. When the first limiting rod 408 abuts against the reset gear assembly 105 (such as the gear of the reset gear assembly 105), the stop bolt 410 is tightened, and the bottom of the stop bolt 410 abuts against the fourth bottom plate 401, so that the second fixing block 404 is stationary on the first slide rail 402, and the angle of the reset gear assembly 105 is prevented from changing, and the reset gear assembly 105 is prevented from rotating before welding.

[0097] Preferably, a plurality of first fixing holes 406 of different heights are provided on the first vertical plate 405, and the second driving mechanism 407 is a second cylinder, which is connected to the first fixing hole 406 of the first vertical plate 405 via an L-shaped fixing bracket 409. By selecting the first fixing holes 406 of different heights, the height of the second cylinder is adjusted to meet the limiting requirements of the reset gear assembly 105 in the throttle body 100 of different models or specifications.

[0098] The fourth bottom plate 401 is connected to the first fixing plate 303 .

[0099] The welding mechanism 500 includes a second fixed plate 501, on which a second vertical plate 502 is provided, a slide base 503 is provided on one side of the second vertical plate 502, two second mounting plates 504 are provided on both sides of the slide base 503, a second slide rail 505 and a screw rod 506 are provided in parallel between the two second mounting plates 504, the screw rod 506 is provided with a slide plate 515, the slide plate 515 is slidably connected to the second slide rail 505 through a second slider 507, and the slide plate 515 is also connected to the welding machine 513 through a bridge plate 509. For example, in this embodiment 1, two second slide rails 505 are provided, and the upper and lower parts of the slide plate 515 are connected respectively through corresponding second sliders 507, and the two second slide rails 505 correspond to the upper and lower parts of the screw rod 506, respectively, to improve the stability of the movement of the slide plate 515.

[0100] The two second mounting plates 504 are further provided with a cover plate 508, which is used to prevent dust and protect the power mechanism of the welding machine 513 (such as the screw rod 506, the slide plate 515, the second slide rail 505 and the second slider 507, etc.), and the cover plate 508 is located between the slide plate 515 and the bridge plate 509;

[0101] A scale part 510 is provided on the top of the slide base 503, and an indication part 511 is provided on the top of the slide plate 515. The indication part 511 corresponds to the scale of the scale part 510, and can intuitively reflect the movement of the welding machine 513, making the moving welding machine 513 more convenient and accurate.

[0102] One end of the screw rod 506 passes through one of the second mounting plates 504 and is connected to the screw bolt 512 . By rotating the screw bolt 512 , the screw rod 506 rotates to realize the movement of the welding machine 513 , that is, the welding machine 513 is close to the throttle body 100 or away from the throttle body 100 .

[0103] The second fixed plate 501 is fixed on the workbench 700; the workbench 700 is also provided with a strip hole 701 for limiting the movement of the welding machine 513. A protrusion 514 is provided at the bottom of the welding machine 513. When the screw rod 506 drives the welding machine 513 to move through the slide plate 515, the protrusion 514 moves in the strip hole 701. The design of the strip hole 701 avoids the protrusion 514 of the welding machine 513. Under the requirement that the welding machine 513 welds the throttle shaft 101 and the reset gear assembly 105, the strip hole 701 cooperates with the protrusion 514 to further limit the movement distance (i.e., the movement amount) of the welding machine 513, ensuring that the maximum movement range of the welding machine 513 does not exceed the stroke of the screw rod 506.

[0104] The direction of the strip hole 701 is parallel to the axial direction of the throttle shaft 101 and the direction of the screw rod 506, in order to ensure that the welding machine 513 can move smoothly and complete the welding operation.

[0105] The welding device also includes a scanner 600 for scanning the barcode or QR code of the throttle body 100. The scanner 600 is fixed on the workbench 700 through a bracket 601. The scanner 600 feeds back the scanning information to the control mechanism. Before the first limit rod 408 limits the reset gear assembly 105 and the welding machine 513 welds the throttle shaft 101 and the reset gear assembly 105, the barcode or QR code of the throttle body 100 is first scanned, and the control mechanism determines whether the throttle body 100 is a qualified product in the previous process, and performs a preliminary screening of the throttle body 100 to be welded, so as to avoid the waste of processing time and raw materials caused by setting the angle and welding of unqualified products.

[0106] An application of a welding device for a throttle shaft 101, using the above-mentioned welding device for a throttle shaft 101, the specific steps are as follows:

[0108] S2. If the throttle body 100 is a qualified product in the previous process, the operator adjusts the angle of the reset gear assembly 105 to the corresponding angle, moves the second fixed block 404 along the first slide rail 402 to the vicinity of the reset gear assembly 105, and then tightens the stop bolt 410. The stop bolt 410 is pressed on the fourth bottom plate 401 to fix the position of the second fixed block 404 on the first slide rail 402, and then adjusts the height of the first limit rod 408 through the second cylinder so that the first limit rod 408 is against the gear of the reset gear assembly 105. At this time, the first limit rod 408 keeps the angle of the reset gear assembly 105 at the corresponding angle, which is convenient for the subsequent welding operation of the throttle shaft 101 and the reset gear assembly 105.

[0109] S3, the operator screws the bolt 512 to drive the slide plate 515 to move along the second slide rail 505 through the screw rod 506, and the slide plate 515 moves the welding machine 513 to the corresponding position to facilitate the subsequent welding operation of the throttle shaft 101 and the reset gear assembly 105;

[0110] S4, the control mechanism controls the first cylinder to move the upper pressure head 302, the upper pressure head 302 and the first bottom plate jointly press the throttle body 100, the inclined surface of the lower pressure head 201 adjusts the angle of the throttle plate 102, and indirectly adjusts the circumferential rotation angle of the throttle shaft 101 to a corresponding angle, at which time the relative position of the throttle shaft 101 and the reset gear assembly 105 is a welding position;

[0111] S5. The control mechanism controls the welding machine 513 to weld the connection position between the throttle shaft 101 and the reset gear assembly 105 to complete the welding operation.

When the throttle body 100 is placed on the first base plate 206, before welding, the third driving mechanism 807 moves the third fixed block 804 to the right, controls the annular limiting portion 809 to press the reset gear assembly 105 to prevent the reset gear assembly 105 from falling off, and after welding, the third driving mechanism 807 moves the third fixed block 804 to the left, controls the annular limiting portion 809 to release the reset gear assembly 105, and facilitates the removal of the throttle body 100 after welding.
