Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of throttle processing and fixing, in particular to a device for processing electronic throttle. BACKGROUND
[0002] In the process of the transformation of the automobile industry from "mechanical control" to "electronic control and intelligence", electronic throttle gradually replaces traditional mechanical pull line throttle and becomes the "core execution center" of the engine electronic control system. From the perspective of structural design, the special-shaped shell of the electronic throttle is the key to realizing functional integration: the port part is responsible for docking with the intake pipe, and the four evenly arranged mounting seats on the side are fixed by bolts to ensure that the ports are flush; the electric control driving part integrates the motor, the reduction gear set and the sensor to form an independent driving unit. Although this "functional division + special-shaped structure" design meets the electronic control requirements, it also poses a process difficulty for production assembly, especially the fixing process of the valve plate and the center shaft. The "port part (low cross section) + electric control driving part (high cross section)" of the electronic throttle shell forms an asymmetric structure, and the traditional "step table + manual support" positioning method has natural defects: the step table can only roughly limit the shell through the height difference between the upper and lower parts, and cannot constrain the circumferential rotation and radial deviation of the shell. When manually supporting, the worker needs to concentrate the force of one hand on the electric control driving part to ensure the stability of the shell, and the center shaft, as the rotating carrier of the valve plate, needs to be kept horizontal through the limit of the jigger, so as to ensure that the screw holes of the valve plate and the center shaft are completely aligned. The hand holding the jigger also needs to hold the jigger to limit and support the center shaft, and the other hand of the worker needs to put the screw into the screw hole aligned with the valve plate and the center shaft, and then complete the assembly of the screw through the electric screwdriver. During the screw tightening process, the slight movement of the shell or the center shaft will be transmitted to the worker's hand through the jigger, causing the jigger to deviate, and then causing the center shaft to tilt. At this time, the screw hole alignment deviates, and the end of the electric screwdriver is easy to scratch the surface of the valve plate or the sensor mounting surface inside the shell. The worker needs to complete "supporting the shell (offsetting the center of gravity)" and "holding the jigger to limit the center shaft" with one hand, and the force directions of the two actions are perpendicular to each other, which is easy to cause hand muscle fatigue, and then causes the action precision to decrease, affecting the quality of the product.

The valve seat pressing assembly is further provided on the rear slider for pressing down the material; Valve plate limiting assembly: The processing table is also equipped with a valve plate limiting assembly that supports materials.
[0005] To ensure that the valve plate of the electronic throttle is in a horizontal position, the present invention improves upon this invention by including a crossbeam, a lifter, a lift seat, bolts, and a limit frame. The middle part of the processing table is provided with a hollow hole, and the left and right sides of the crossbeam are connected to the sidewalls of the hollow hole. The output end of the lifter passes through the crossbeam and is connected to the lift seat. The lift seat is provided with a U-shaped limit frame, and bolts connected to the limit frame are provided at the four corners of the lift seat.
[0006] To facilitate the stable movement of the two sets of first forward and reverse toothed rods, the present invention is improved in that the driver includes a cover, a first motor, a worm gear and a worm. The cover is provided on one side above the processing table. The worm and two worm gears are provided inside the cover. The worm meshes with the two worm gears. The first forward and reverse toothed rods pass through the first sliding frame and the cover and are connected to the center of the worm gear. The output end of the first motor passes through the cover and is connected to the worm.
[0007] To ensure the stability of the slide's movement, the present invention is improved by providing symmetrical slide rails on both the front and rear sides of the processing table, with the hollowed-out holes located between the two slide rails, and a track groove adapted to the slide rails located below the slide.
[0008] To facilitate longitudinal clamping of the electronic throttle body, the present invention is improved in that the valve seat pressing assembly includes a third slide frame, a third motor, a screw, a lifting plate, and an upper support. The third slide frame is provided above the rear slide block, and a third slide groove is provided on the front side of the third slide frame. The screw is rotatably disposed in the third slide groove. The output end of the third motor passes through the third slide frame and is connected to the screw. One end of the lifting plate extends into the third slide frame and is threadedly connected to the screw. An upper support is provided below the other end of the lifting plate.
[0009] Preferably, the lower support includes a lower stud, a lower connecting seat, and a lower positioning rod. The front slider and the rear slider are both provided with lower studs. The lower positioning rod is provided below the lower stud and is threadedly connected to the lower stud. The lower stud, the lower connecting seat, and the lower positioning rod are arranged concentrically. The outer diameter of the lower positioning rod is smaller than the outer diameter of the lower connecting seat.
[0010] Preferably, the upper support includes an upper stud, an upper connecting seat, and an upper positioning rod. The upper stud is provided below the lifting plate, and the corresponding upper stud is located above the lower stud of the corresponding rear slider.

[0014] (III) Beneficial Effects Compared with the prior art, the present invention provides an apparatus for processing electronic throttle valves, which has the following beneficial effects: This electronic throttle body machining device uses a driver (worm gear + first motor) to synchronously drive two sets of first positive and negative toothed rods to rotate, causing the left and right symmetrical slide plates to move towards each other along the first slide groove. The valve seat bearing assembly above the slide plate moves with the slide plate and can automatically adjust the spacing according to the length of the electronic throttle body. When the second positive and negative toothed rods in the second slide frame rotate, they drive the front slide plate, the rear slide plate, and the lower support component below to move towards each other. The lower positioning rod of the lower support component can be inserted into the mounting seat on the periphery of the housing port to complete the radial and circumferential limiting of the valve body. The third motor drives the screw of the valve seat pressing assembly to rotate, which in turn drives the lifting plate and the upper support to descend. The upper and lower positioning rods are aligned vertically and press the housing together to avoid uneven force when manually supporting it, which could cause the housing to shake. At the hollowed-out hole in the center of the processing table, the lifting device drives the lifting seat to rise, and the U-shaped limit frame lifts the valve plate on the central shaft from below, keeping the valve plate horizontal, in preparation for the subsequent screw fixing of the central shaft and the valve plate. The valve plate limiting assembly independently undertakes the central shaft limiting function, eliminating the need for manual holding of the lever, and the equipment leaves ample processing space above the electronic throttle body to be processed.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] Please see Figures 1-8An apparatus for processing electronic throttle valves includes a processing table 1, and further includes: The centering assembly includes a first sliding frame 2, a sliding plate 3, a first positive and negative thread rod 4, and a driver. The machining table 1 has first sliding frames 2 symmetrically arranged on its front and rear sides. A first sliding groove is provided on the adjacent side of the two first sliding frames 2. The first positive and negative thread rod 4 is rotatably arranged within the first sliding groove. The machining table 1 also has a driver that drives the two first positive and negative thread rods 4 to rotate. Two sliding plates 3 are symmetrically arranged on the left and right sides of the machining table 1. The front and rear ends of the sliding plates 3 extend into the corresponding first sliding grooves and are threadedly connected to the first positive and negative thread rods 4. The driver includes a cover 15 and a first motor 16. The machining table 1 has a worm gear 17 and a worm 18. A cover 15 is provided on one side above the machining table 1. The cover 15 contains a worm 18 and two worm gears 17. The worm 18 meshes with the two worm gears 17. The first positive and negative toothed rod 4 passes through the first slide frame 2 and the cover 15 and is connected to the center of the worm gears 17. The output end of the first motor 16 passes through the cover 15 and is connected to the worm 18. Slide rails 19 are symmetrically arranged on the front and rear sides of the machining table 1. The hollow hole is arranged between the two slide rails 19. A track groove adapted to the slide rails 19 is provided below the slide plate 3. The first motor 16 of the driver is started, and the output end of the motor drives the worm 18 inside the cover 15 to rotate. The worm 18 simultaneously meshes with two worm gears 17 (transmission ratio 1:30, to ensure synchronization), thereby driving the two sets of first positive and negative thread rods 4 (inside the first sliding frame 2 on the front and rear sides) to rotate synchronously. Since the left and right sections of the first positive and negative thread rods 4 have opposite thread directions, the left and right slide plates 3 connected to them move towards each other along the first slide groove. The track groove below the slide plate 3 slides and engages with the slide rail 19 of the processing table 1, restricting the slide plate 3 to only move laterally (without vertical movement). The valve seat bearing assembly above the slide plate 3 moves with the slide plate 3 and can automatically adjust the spacing according to the length of the electronic throttle body (compatible with 50-150mm specifications). In this embodiment, the valve seat bearing assembly includes a second slide frame 5, a second motor 6, a second positive and negative thread rod 7, a front slider 8, a rear slider 9, and a lower support member. The slide plate 3 is provided with a second slide frame 5, and a second slide groove is provided on the second slide frame 5. The second positive and negative thread rod 7 is rotatably disposed in the second slide groove. Lower support members are symmetrically arranged on the front and rear sides above the second positive and negative thread rod 7. A front slider 8 is provided below the lower support member on the front side, extending into the second slide groove and threadedly connected to the second positive and negative thread rod 7. A front slider 8 is provided below the lower support member on the rear side, extending into the second slide groove and threadedly connected to the second positive and negative thread rod 7. The rear slider 9, connected by threads, starts the second motor 6, which drives the second positive and negative thread rod 7 in the second slide frame 5 to rotate (the front and rear sections of the thread rotate in opposite directions), causing the front slider 8, the rear slider 9 and the lower support above to move towards each other. The lower support includes a lower stud 24, a lower connecting seat 25 and a lower positioning rod 26. The front slider 8 and the rear slider 9 are both provided with lower studs 24. The lower positioning rod 26 is provided below the lower connecting seat 25 which is threaded to the lower stud 24. The lower stud 24, the lower connecting seat 25 and the lower positioning rod 26 are arranged concentrically. The outer diameter of the lower positioning rod 26 is smaller than the outer diameter of the lower connecting seat 25. The lower positioning rod 26 of the lower support is inserted into the mounting seat around the electronic throttle port to limit the four sets of mounting seats around the electronic throttle port. In actual use, it is necessary to select a lower connecting seat 25 with a lower positioning rod 26 of appropriate specification and connect it to the lower stud 24 according to the hole diameter of the mounting seat around the electronic throttle port. Depending on the requirements, the lower connecting seat 25 and the lower stud 24 can also be connected by plugging and magnetic block. As long as the lower connecting seat 25 and the lower positioning rod 26 can stably support the mounting seat of the electronic throttle port, it is sufficient. In this embodiment, the rear slider 9 is further provided with a valve seat pressing assembly for pressing down materials. The valve seat pressing assembly includes a third slide frame 20, a third motor 21, a screw 22, a lifting plate 23, and an upper support. The third slide frame 20 is provided above the rear slider 9. A third slide groove is provided on the front side of the third slide frame 20. The screw 22 is rotatably disposed in the third slide groove. The output end of the third motor 21 passes through the third slide frame 20 and is connected to the screw 22. One end of the lifting plate 23 extends into the third slide frame 20 and is threadedly connected to the screw 22. An upper support is provided below the other end of the lifting plate 23. The upper support includes an upper stud 27, an upper connecting seat 28, and an upper positioning element. The upper positioning rod 29 has an upper stud 27 located below the lifting plate 23. The upper stud 27 is located above the lower stud 24 of the corresponding rear slider 9. The upper positioning rod 29 has an upper connecting seat 28 that is threadedly connected to the upper stud 27. The upper stud 27, the upper connecting seat 28, and the upper positioning rod 29 are arranged concentrically. The outer diameter of the upper positioning rod 29 is smaller than the outer diameter of the lower connecting seat 25. The upper positioning rod 29 and the lower positioning rod 26 have rounded edges 32 on their adjacent sides. The third motor 21 of the valve seat pressing assembly is activated. The motor drives the screw 22 in the third slide frame 20 to rotate. The lifting plate 23, which is threadedly connected to the screw 22, moves downward along the third slide groove, causing the upper support component below to descend synchronously. The upper positioning rod 29 and the lower positioning rod 26 are aligned vertically. Finally, the upper positioning rod 29 is inserted into the corresponding hole of the electric control drive part of the housing (or pressed against the upper surface of the housing), and cooperates with the lower positioning rod 26 to form a rigid clamping between the upper and lower parts. At this time, the limiting and fixing of the electronic throttle housing is completed. The rounded 32 design on the side of the upper positioning rod 29 and the lower positioning rod 26 near each other avoids scratching the surface of the housing mounting seat. At the same time, the rigid clamping completely eliminates the vertical movement of the housing, solving the core pain point of "uneven force causing housing shaking" when manually supporting it, and providing a stable foundation for subsequent screw tightening. At this time, the central shaft and valve plate inside the electronic throttle body are not limited. Therefore, the processing table 1 is also equipped with a valve plate limiting component to support the material.
[0019] In this embodiment, the limiting assembly includes a crossbeam 10, a lifter 11, a lifting seat 12, bolts 13, and a limiting frame 14. The middle part of the processing table 1 is provided with a hollow hole. The left and right sides of the crossbeam 10 are connected to the sidewalls of the hollow hole. The output end of the lifter 11 passes through the crossbeam 10 and is connected to the lifting seat 12. The lifting seat 12 is provided with a U-shaped limiting frame 14. Bolts 13 connected to the limiting frame 14 are provided at the four corners of the lifting seat 12. Support legs 30 are also provided at the four corners below the processing table 1. Guide rods 31 passing through the crossbeam 10 are symmetrically provided on the left and right sides below the lifting seat 12. The lifting device 11 (such as an electric push rod or hydraulic cylinder) is activated, and the output end drives the lifting seat 12 to move upward along the guide rod 31 (through the crossbeam 10 to ensure vertical lifting). The U-shaped limit bracket 14 on the lifting seat 12 extends from the cutout hole of the processing table 1 until the top wall of the limit bracket 14 is in contact with the left and right sides of the valve plate. The bolts 13 at the four corners of the lifting seat 12 facilitate the replacement of the limit bracket 14 with the corresponding electronic throttle valve plate, ensuring that the valve plate is in a horizontal position without the need for manual holding of the lever, avoiding the conflict of the traditional "one hand supporting + one hand limiting" action. A flexible rubber pad can be installed on the inner wall of the limit bracket 14, which can not only stably support the central shaft, but also avoid scratching the surface of the valve plate, while ensuring that the screw holes of the valve plate and the central shaft are fully aligned, preparing for screw assembly. In this embodiment, the first motor 16, the second motor 6 and the third motor 21 can all be servo motors: ASD-B2-0721-B, used with a Roots encoder, which can accurately control the number of rotations of the corresponding output shaft, and with the transmission ratio of the corresponding transmission system, can control the position of the corresponding lower support and upper support. Lifter 11 can be equipped with an electric push rod: DT300; A controller can be installed on the processing table 1 to synchronously control multiple motors and the lifting device 11 to work together. The controller can be a PLC: S7-1200 (1214C). The first positive and negative thread rod 4, the second positive and negative thread rod 7, and the screw 22 are treated with 40Cr tempering. They are used in conjunction with the bronze nuts of the slide plate 3, the front slide block 8, the rear slide block 9, and the lifting plate 23 to reduce the thread meshing gap and avoid the "creeping phenomenon" caused by vibration. The slide rail 19 and the track groove are hardened (HRC58-62) and lubricated with grease (high temperature lithium grease) to reduce the sliding friction coefficient (≤0.03) and ensure that the slide plate 3 moves smoothly without jumping. As needed, elastic bellows-type dust covers can be added to the first slide frame 2, the second slide frame 5, and the third slide frame 20 to avoid the impact of dust on the equipment. In order to prevent the two free ends of the limit frame 14 from squeezing and deforming the valve plate, in addition to adding friction pads to the two free ends of the limit frame 14, the top wall of the limit frame 14 can be made with a contour groove to make the limit frame 14 stably support the valve plate and the central shaft and ensure the limit of the central shaft and the valve plate.
