[0028] 1. This utility model discloses a throttle shaft angle-setting device. An upper pressure head and a first base plate press the throttle body together, while a lower pressure head is embedded in the throttle passage (or "throttle intake channel"). The inclined surface at the top of the lower pressure head presses the throttle plate, adjusting the flip angle of the throttle plate and causing the throttle shaft to rotate circumferentially. This ultimately achieves throttle shaft angle adjustment. As long as the throttle plate is in contact with the inclined surface of the lower pressure head, the circumferential angle of the throttle shaft is adjusted to the specified angle. This facilitates subsequent welding of the throttle shaft and reset gear assembly, more efficiently and accurately determining the angle of the throttle plate, achieving a highly efficient throttle shaft angle-setting function, and improving the efficiency of throttle shaft angle preparation before welding.

The lower pressure head is connected to the second base plate through an elastic element. The elastic element increases the pressing force of the lower pressure head acting on the throttle body from bottom to top. Because the elastic pressure of the elastic element can prevent bending or damage to the throttle body, it will not increase the pressure on the throttle body and will avoid damage to the throttle body.
[0030] 3. The throttle shaft fixing device of this utility model is further provided with a detection mechanism for detecting the position of the throttle plate. The first laser measuring head and the second laser measuring head of the detection mechanism are respectively used to detect the position of the throttle plate on both sides of the throttle shaft, so as to ensure that the throttle plate is flipped into place and the circumferential fixing angle of the throttle shaft is accurate.

[0048] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.
[0049] See Figures 1 to 14Specific embodiment 1: This embodiment 1 provides a throttle body angle fixing device, including a first drive 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 element 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 element 205. The elastic element 205 (such as a spring) is located in the first through hole 207.
[0050] The first drive mechanism 301 (e.g., a cylinder) drives the upper pressure head 302 to press against the throttle body 100 placed on top of the first base plate 206. The first base 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 channel 103. Under the action of the elastic element 205, the inclined surface 202 of the pressure head 201 presses against the throttle plate 102 on the throttle shaft 101 from bottom to top. At this time, the force exerted by the lower pressure head 201 on the throttle plate 102 is controllable and elastic, and will not bend the throttle shaft 101. This achieves the circumferential rotation of the throttle shaft 101 and adjusts the angle of the throttle shaft 101 without damaging the throttle shaft 101.
[0051] The top of the pressure head 201 is provided with an inclined surface 202, which corresponds to the throttle plate 102 of the throttle body 100. The inclined surface 202 is used to flip the throttle plate 102. When the throttle plate 102 flips, it drives the throttle shaft 101 to rotate circumferentially, thereby adjusting the angle of the throttle shaft 101 until the throttle plate 102 is in contact with the inclined surface 202. At this time, the circumferential rotation angle of the throttle shaft 101 reaches the specified angle (that is, the angle at which the throttle shaft 101 can be welded to the reset gear assembly 105), which facilitates the subsequent welding of the throttle shaft 101 to the reset gear assembly 105, and the welding angle is accurate. A groove 203 is provided in the middle of the inclined surface 202. The groove 203 corresponds to the throttle body 100 throttle shaft 101. That is, the throttle shaft 101 is embedded in the groove 203. The inclined surfaces 202 of the lower pressure head 201 on both sides of the groove 203 respectively fit the throttle plate 102 on both sides of the throttle shaft 101, ensuring that the throttle plate 102 can fit the inclined surface 202 of the lower pressure head, ensuring that the angle adjustment of the inclined surface 202 of the lower pressure head 201 on the throttle shaft 101 is more accurate, and realizing the precise angle setting function of the throttle shaft 101.
[0052] A third base plate 212 is provided below the second base plate 210. The second base plate 210 and the third base plate 212 are connected by a support pad 213. The second base plate 210 has a second guide hole 211 that runs vertically through it. A second guide rod 204 is provided at the bottom of the pressing head 201. The second guide rod 204 is located in the first through hole 207 and moves vertically within the second guide hole 211. A space is formed between the second base plate 210 and the third base 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 pressing 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 pressing head 201's angle-fixing function on the throttle shaft 101. In this embodiment 1, there are two second guide rods 204, corresponding to both sides of the elastic member 205, resulting in a more stable guiding effect.
[0053] The angle-fixing device also includes a first fixing plate 303, a third base plate 212 fixed on the first fixing plate 303, the first fixing plate 303 is also provided with a number of support columns 304, the top of the support columns 304 is connected to a first mounting plate 305, the first mounting plate 305 fixes the first drive mechanism 301, the movable end of the first drive mechanism 301 is connected to a first connecting plate 306, the bottom of the first connecting plate 306 is connected to an upper pressure head 302, and the upper pressure head 302 corresponds to the mounting hole 104 of the throttle body 100.
[0054] The upper end of the upper pressure 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 pressure head 302 can be adjusted, which is suitable for pressing and fixing different models of throttle body 100.
[0055] The first base plate 206 is provided with at least three first elevation blocks 208 for supporting the throttle body 100, two of which have first positioning pins 209 on their tops for embedding into the mounting holes 104 of the throttle body 100. For example, by placing the throttle body 100 on the first elevation blocks 208, with the two first positioning pins 209 respectively embedded into two mounting holes 104 of the throttle body 100 (e.g., two diagonally opposite mounting holes 104), the height of the three first elevation blocks 208 can be adjusted to ensure that the central axis of the throttle body 100 channel is vertical and that the axis of the throttle shaft 101 is horizontal. Preferably, the upper pressure head 302 and two of the first shims 208 are located on the same side of the throttle body 100, so as to keep the throttle body 100 pressed and fixed in a relatively vertical direction as much as possible, avoiding pressure dispersion, damage to the throttle body 100, or skewing of the pressed throttle body 100; at the same time, this design can also effectively prevent the throttle body 100 from being installed backwards, thus playing a role in preventing errors.
[0056] The pressure head 201 is cylindrical in shape and matches the shape of the throttle passage 103. This ensures that the pressure head 201 can be embedded in the throttle passage 103 and maximizes the area of the inclined surface 202 at the top of the pressure head 201. This helps to more accurately adjust the flip angle of the throttle plate 102 and adjust the circumferential rotation angle of the throttle shaft 101, thereby more accurately achieving the angle-fixing function of the throttle shaft 101.
[0057] The angle-fixing 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 tilt angle of the straight line corresponding to the bottom ends of the first laser measuring head 318 and the second laser measuring head 319 is the same as the tilt angle of the inclined surface 202 at the top of the lower pressure head 201. For example, the first laser measuring head 318... The bottom of the first laser measuring head 318 corresponds to one side area (the higher side) of the throttle body plate 102, and the bottom of the second laser measuring head 319 corresponds to the other side area (the lower side) of the throttle body plate 102. As long as the bottom of the first laser measuring head 318 can detect one side area of the throttle body plate 102, and the bottom of the second laser measuring head 319 can detect the other side area of the throttle body plate 102, it can be determined that the throttle body plate 102 has been flipped to the designated position. At this time, the circumferential angle of the throttle body shaft 101 is also adjusted to the designated angle, which facilitates the precise welding between the throttle body shaft 101 and the reset gear assembly 105.
[0058] 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. This is also to ensure the accuracy of the calculation of the throttle plate 102 flip angle by the first laser measuring head 318 and the second laser measuring head 319 through detecting the position information of the throttle plate 102.
[0059] The first connecting plate 306 is also provided with two second mounting holes 309. The first laser measuring head 318 and the second laser measuring head 319 pass through the two second mounting holes 309 respectively and are clamped by two clamping blocks 310. The clamping blocks 310 enable the height of the first laser measuring head 318 and the second laser measuring head 319 to be adjusted, or the height of the first laser measuring head 318 and the height of the second laser measuring head 319 can also be adjusted separately, to match different specifications of throttle body 100 or to meet the angle requirements of throttle shaft 101 with different tilt angles.
[0060] The tops of the two clamping blocks 310 are connected to the first connecting block 311. Each end of the first connecting block 311 is 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, this is to ensure that the first laser measuring head 318 and the second laser measuring head 319 can move vertically up and down.
[0061] The bottom of the first connecting block 311 is also provided with a pressure block 315. The pressure block 315 is provided with a third guide hole 316 corresponding to the position of the first guide block. The first guide rod 312 passes through the third guide hole 316. The pressure block 315 is also provided with side grooves 317 on both sides, into which the first laser measuring head 318 and the second laser measuring head 319 are respectively embedded. The pressure block 315 is used for the installation and positioning of the first laser measuring head 318 and the second laser measuring head 319, thereby increasing stability.
[0062] The steps for using a throttle body shaft angle setting device are as follows: First, the mounting hole 104 of the throttle body 100 is aligned with the first positioning pin 209 and placed on three first raising blocks 208. The lower pressing head 201 is simultaneously embedded into the throttle channel 103 and aligns with the throttle plate 102 to adjust the angle of the throttle body shaft 101. The control mechanism controls the first driving mechanism 301 to drive the first connecting plate 306 to move downward, and the upper pressing head 302 presses against the throttle body 100. The first laser measuring head 318 and the second laser measuring head 319 move downward simultaneously to detect the position of the throttle plate 102 and feed the relevant information back to the control mechanism (such as a PLC). The control mechanism then determines whether the position of the throttle plate 102 is accurate, and thus determines whether the angle of the throttle body shaft 101 is accurate.
[0063] Specific embodiment 2, this embodiment 2 provides a throttle body angle fixing device, characterized in that: the angle fixing device includes a first drive mechanism 301, an upper pressure head 302, a first base plate 206, and a lower pressure head 201, the bottom of the lower pressure head 201 being connected to the first base plate 206;
[0064] The top of the lower pressure head 201 is provided with an inclined surface 202 for flipping the throttle plate 102 to adjust the angle of the throttle shaft 101. The inclined surface 202 corresponds to the throttle plate 102 of the throttle body 100. The middle of the inclined surface 202 is provided with a groove 203, which corresponds to the throttle shaft 101 of the throttle body 100. The first drive mechanism 301 drives the upper pressure head 302 to press against the throttle body 100 placed on the top of the first base plate 206. The lower pressure head 201 is embedded in the throttle channel 103. The inclined surface 202 of the lower pressure head 201 presses the throttle plate 102 on the throttle shaft 101 from bottom to top.
[0065] The angle-fixing device also includes a first fixing plate 303, a first base plate 206 fixed on the first fixing plate 303, the first fixing plate 303 is also provided with a plurality of support columns 304, the top of the support columns 304 is connected to a first mounting plate 305, the first mounting plate 305 fixes a first drive mechanism 301, the movable end of the first drive mechanism 301 is connected to a first connecting plate 306, the bottom of the first connecting plate 306 is connected to an upper pressure head 302, and the upper pressure head 302 corresponds to the mounting hole 104 of the throttle body 100.
[0066] In this embodiment 2, the pressure head 201 can also rotate the throttle plate 102, thereby achieving the function of fixing the angle of the throttle shaft 101. The pressure head 201 and the first base plate 206 press the throttle body 100 together.
[0067] The angle-fixing device also includes a detection mechanism and a control 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.
[0068] The control mechanism controls the operation of the first drive mechanism 301;
[0069] The first laser measuring head 318 and the second laser measuring head 319 feed back information to the control mechanism, which then determines whether the position of the throttle plate 102 is accurate, and further determines whether the angle of the throttle shaft 101 is accurate.
