[0033] 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.

[0034] See Figures 1 to 4 In specific embodiment 1, this embodiment 1 provides a positioning fixture for laser marking of a throttle body, including a transverse fixing plate 2 and a longitudinal fixing plate 1 connected to each other. For example, the bottom of the longitudinal fixing plate 1 is connected to the upper surface of the transverse fixing plate 2. The longitudinal fixing plate 1 is provided with a first moving mechanism for moving the throttle body 6 up and down. The first moving mechanism includes two positioning pins for fixing the throttle body 6 and a distance adjusting mechanism for adjusting the distance between the two positioning pins.

[0035] The first moving mechanism includes a first slide rail 1-1 and a second slide rail 1-2 arranged longitudinally on the longitudinal fixed plate 1. The first slide rail 1-1 and the second slide rail 1-2 are parallel. The positioning pins include a first positioning pin 3-6 and a second positioning pin 4-6. The distance adjustment mechanism includes a first slide groove 3-1 and a second slide groove 4-1.

[0036] The first slide rail 1-1 is connected to the first connecting block 3 via the first slider 1-7. The first connecting block 3 can slide up and down along the first slide rail 1-1 to adjust its height. The second slide rail 1-2 is connected to the second connecting block 4 via the second slider 1-8. The second connecting block 4 can slide up and down along the second slide rail 1-2 to adjust its height. The first slide rail 1-1 has a first limiting block 1-5 at its top to prevent the first slider 1-7 from slipping off the top of the first slide rail 1-1. The second slide rail 1-2 has a second limiting block 1-6 at its top to prevent the second slider 1-8 from slipping off the top of the second slide rail 1-2.

[0037] The first connecting block 3 has a transverse first sliding groove 3-1 on the side facing away from the first slide rail 1-1. The first sliding groove 3-1 connects to the third connecting block 3-5. The third connecting block 3-5 has a first positioning pin 3-6 on the side facing away from the first sliding groove 3-1. The first positioning pin 3-6 can slide laterally (e.g., left and right) along the first sliding groove 3-1 through the third connecting block 3-5. The second connecting block 4 has a transverse second sliding groove 4-1 on the side facing away from the second slide rail 1-2. The second sliding groove 4-1 connects to the fourth connecting block 4-5. The fourth connecting block 4-5 has a second positioning pin 4-6 on the side facing away from the second sliding groove 4-1. The second positioning pin 4-6 can slide laterally (e.g., left and right) along the second sliding groove 4-1 through the fourth connecting block 4-5.

[0038] The third connecting block 3-5, carrying the first positioning pin 3-6, moves horizontally within the first slide groove 3-1, while the fourth connecting block 4-5, carrying the second positioning pin 4-6, moves horizontally within the second slide groove 4-1. Adjusting the distance between the first positioning pin 3-6 and the second positioning pin 4-6 allows them to be inserted into the corresponding mounting holes of different throttle body 6 products, enabling the installation of throttle body 6 products of different specifications onto the positioning fixture. Simultaneously, by synchronously moving the first positioning pin 3-6 and the second positioning pin 4-6 horizontally, the horizontal position of the throttle body 6 can be adjusted, ensuring that the throttle body 6 is positioned directly below the laser marking machine for easier laser marking. Then, the first connecting block 3, along with the first positioning pin 3-6, moves up and down along the first slide rail 1-1, and the second connecting block 4, along with the second positioning pin 4-6, moves up and down along the second slide rail 1-2. By adjusting the height of the first connecting block 3 and the height of the second connecting block 4, the throttle body 6 moves up and down, and the overall height of the throttle body 6 is adjusted to ensure that the marking area of ​​the throttle body 6 (such as the marking area 6-1 of the dust cover) is placed at the specified height, which is convenient for the laser marking machine to mark.

[0039] The longitudinal fixing plate 1 has a third slide groove 1-3 and a fourth slide groove 1-4 at both ends. The first positioning block 3-3 is fixed in the third slide groove 1-3 on one side of the longitudinal fixing plate 1 by the first screw 3-4. At the same time, the first positioning block 3-3 abuts against the first connecting block 3. The first positioning block 3-3 and the first slide rail 1-1 together clamp the first connecting block 3, which has reached the specified height, to achieve positioning of the first connecting block 3 and ensure that the first connecting block 3 will not slide accidentally in the vertical direction on the first slide rail 1-1. The second positioning block 4-3 is fixed in the fourth slide groove 1-4 on the other side of the longitudinal fixing plate 1 by the second screw 4-4. At the same time, the second positioning block 4-3 abuts against the second connecting block 4. The second positioning block 4-3 and the second slide rail 1-2 together clamp the second connecting block 4, which has reached the specified height, to achieve positioning of the second connecting block 4 and ensure that the second connecting block 4 will not slide accidentally in the vertical direction on the second slide rail 1-2.

[0040] The first connecting block 3 has a first positioning hole 3-2. The third screw 3-7 is threaded into the first positioning hole 3-2 and then abuts against the third connecting block 3-5, positioning the third connecting block 3-5 and ensuring that the first positioning pin 3-6 does not accidentally slide horizontally. Preferably, there are three first positioning holes 3-2, evenly distributed on the top of the first connecting block 3, each positioning the third connecting block 3-5 at a different horizontal position. The second connecting block 4 has a second positioning hole 4-2. The fourth screw 4-7 is threaded into the second positioning hole 4-2 and then abuts against the fourth connecting block 4-5, positioning the fourth connecting block 4-5 and ensuring that the second positioning pin 4-6 does not accidentally slide horizontally. Preferably, there are three second positioning holes 4-2, evenly distributed on the top of the second connecting block 4, each positioning the fourth connecting block 4-5 at a different horizontal position.

[0041] Below the transverse fixing plate 2, there is a base plate 5. The top of the base plate 5 has a third slide rail 5-1. The transverse fixing plate 2 is connected to the third slide rail 5-1 via a third slider 5-2. The third slide rail 5-1 is parallel to the first positioning pin 3-6 and the second positioning pin 4-6. There are two third slide rails 5-1, arranged parallel to each other on the base plate 5. The base plate 5 slides back and forth on the third slide rail 5-1, adjusting the front and rear positions of the transverse fixing plate 2 and the longitudinal fixing plate 1 to ensure that the throttle valve 6, fixed by the first positioning pin 3-6 and the second positioning pin 4-6, is located directly below the laser marking machine, facilitating laser marking.

[0042] One or both ends of the transverse fixing plate 2 are provided with a third positioning block 2-1. The third positioning block 2-1 is provided with a third positioning hole. The fifth screw 2-2 is threadedly connected to the third positioning hole and abuts against the base plate 5. This is used to position the transverse fixing plate 2 at the designated position on the base plate 5, preventing accidental sliding on the third slide rail 5-1 and ensuring that the throttle valve 6 is located directly below the laser marking machine. There are two third positioning blocks 2-1, located on both sides of the transverse fixing plate 2. Both ends of the transverse fixing plate 2 are simultaneously fixed to the position of the base plate 5.

[0043] A reinforcing plate 2-3 is provided between the longitudinal fixing plate 1 and the transverse fixing plate 2 to increase the connection stability between the longitudinal fixing plate 1 and the transverse fixing plate 2.

[0044] This embodiment 1 provides a positioning fixture for laser marking of throttle valves. By adjusting the horizontal distance between the first positioning pin 3-6 and the second positioning pin 4-6, throttle valves 6 of different specifications or models can be installed. Then, the height of the throttle valve 6 can be adjusted by the first slide rail 1-1 and the second slide rail 1-2, and the front and rear position of the throttle valve 6 can be adjusted by moving the transverse fixing plate 2 in the front and back direction. In other words, the position of the throttle valve 6 can be adjusted in three dimensions to ensure that the marking area of ​​the throttle valve 6 (such as the marking area 6-1 of the dust cover) is located at a specified height directly below the laser marking machine, which facilitates the laser marking machine to mark throttle valves 6 of different specifications or models.
