Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to an integrated device for testing and pressing electronic throttle valve shafts. Background Technology

[0002] Electronic throttle bodies have become increasingly widely used with the development of automotive technology, gradually replacing traditional mechanical throttle bodies. Electronic throttle bodies are used to build electronic throttle control systems, which can achieve optimal torque output across the entire engine range, precisely control throttle opening, and improve engine emissions performance. Therefore, precise control of throttle opening is crucial. Current electronic throttle bodies have two shafts, requiring two press-fitting processes. Due to the different lengths of the two shafts, current technology generally uses two separate devices, requiring multiple handling and positioning operations, which is time-consuming and labor-intensive. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an integrated device for pressing and testing electronic throttle valve shafts, which can complete the pressing of multiple valve shafts at one time, improve assembly efficiency, and ensure correct pressing.

[0004] Specifically, this utility model discloses an integrated testing and inspection device for electronic throttle body shaft press fitting, comprising:

[0005] The frame is equipped with positioning components for fixing the valve body;

[0006] The detection component, mounted on the frame, is used to detect whether the long shaft is placed in the correct orientation;

[0007] A press-fit assembly for press-fitting a long shaft and a short shaft to a valve body includes a press-fitting plate and a press-fitting drive. The press-fitting plate is provided with a long shaft limiting block and a short shaft limiting block for limiting the long shaft and the short shaft. The press-fitting drive provides pressure to press the long shaft and the short shaft into place.

[0008] The advantage of adopting the above technical solution is that it realizes the integration and detection of the long and short shafts of the electronic throttle valve, improves assembly efficiency, and ensures accurate assembly position.

[0009] Furthermore, a press-fit groove is provided inside the short shaft limiting block, and an air suction hole is provided inside the press-fit groove, with an air suction hole connected to an air pipe.

[0010] The advantage of adopting the above technical solution is that, before installation, the short shaft is placed in the short shaft limiting block and fixed by suction. This ensures that the installation of the short shaft will not be offset, which facilitates press-fitting.

[0011] Furthermore, the press-fit drive is vertically fixed on the frame, and a press-fit head is provided at the output end. The press-fit head moves up and down reciprocally. When pressing down, the press-fit head passes through the long shaft limiting block and the short shaft limiting block to press the long shaft and the short shaft onto the valve body.

[0012] The advantage of adopting the above technical solution is that the pressing head provides downward pressure to press the short shaft and the long shaft, ensuring that the pressing is in place.

[0013] Furthermore, the pressing plate is connected to a horizontal moving component and a vertical moving component, and a connecting plate is provided on the frame. Both the horizontal moving component and the vertical moving component are mounted on the connecting plate, which are used to drive the pressing plate to move horizontally and vertically.

[0014] The advantage of adopting the above technical solution is that it enables the horizontal and vertical movement of the pressing plate, and allows the pressing of two bearings to be completed with one pressing head, eliminating the need for secondary handling and effectively improving pressing efficiency.

[0015] Furthermore, the detection assembly includes a mounting plate, a detection camera, and a supplementary light. The detection camera is mounted on the mounting plate, and the supplementary light is mounted on the frame.

[0016] The advantage of adopting the above technical solution is that the detection camera is used to realize long axis retrograde detection, and the supplementary light is set to enable use in dim environments.

[0017] Furthermore, the positioning component is provided with a positioning plate, the positioning plate is provided with a positioning block, and clamping elements are provided on both sides of the positioning plate.

[0018] The advantage of adopting the above technical solution is that the positioning block plays the role of positioning the valve body, ensuring accurate press-fitting position.

[0019] Furthermore, the clamping component includes a clamping shaft, which is connected to a telescopic rotary cylinder, which is installed on both sides of the positioning plate.

[0020] The advantage of adopting the above technical solution is that the setting of the clamping shaft presses the valve body against the positioning plate, ensuring that the valve body does not shake.

[0021] Furthermore, the positioning component is equipped with a movable plate, the movable plate is connected to a movable module, and the movable module drives the positioning component to move between the detection component and the pressing component.

[0022] The advantage of adopting the above technical solution is that the moving module drives the moving plate to move, which in turn drives the entire positioning assembly to move, causing the valve body to move, thus completing the testing and pressing in one go.

[0023] Furthermore, the positioning plate is also provided with a support column for supporting the product, and a support base is connected to the lower side of the support column.

[0024] The advantage of adopting the above technical solution is that the support column provides support for the valve body, preventing product damage during press-fitting.

[0025] Furthermore, the positioning block is fixedly connected to the positioning plate and is provided with a positioning surface for receiving the product and contacting the outer surface of the valve body.

[0026] The advantage of adopting the above technical solution is that the positioning surface is designed to contact the valve body, thus playing a good positioning role. Attached Figure Description

Detailed Implementation

[0036] The present invention will now be described in further detail with reference to the accompanying drawings.

[0037] like Figure 1-3 As shown, this utility model discloses an integrated testing and inspection device for electronic throttle body shaft press-fitting, comprising:

[0038] Frame 1 is equipped with a positioning assembly for fixing the valve body;

[0039] The detection component 2, mounted on the frame 1, is used to detect whether the placement direction of the long shaft 12 is correct;

[0040] A press-fit assembly for press-fitting the long shaft 12 and the short shaft 13 to the valve body includes a press-fitting plate 3 and a press-fitting drive component 4. The press-fitting plate 3 is provided with a long shaft limiting block 31 and a short shaft limiting block 32 for limiting the long shaft 12 and the short shaft 13. The press-fitting drive component 4 provides pressure to press the long shaft 12 and the short shaft 13 into place. The long shaft 12 is used to install the valve plate and drive the valve plate to open and close, thereby realizing the opening and closing of the entire valve body. Since the valve body is provided with a gear set for transmission, the short shaft 13 is used to fix the gear and is installed on the same side as the long shaft 12.

[0041] The advantage of adopting the above technical solution is that it realizes the integration and detection of the long axis 12 and short axis 13 of the electronic throttle valve, improves assembly efficiency, and ensures accurate assembly position.

[0042] Among them, such as Figure 4 As shown, a pressing groove 321 is provided inside the short shaft limiting block 32. The short shaft limiting block 32 is locked to the lower side of the pressing plate 3. The entire pressing groove 321 is set as a cylindrical groove facing downward. A through hole for the pressing head 41 is provided in the middle of the top of the pressing groove 321. Suction holes 322 are provided around the top of the pressing groove 321. Multiple suction holes 322 are provided in the short shaft limiting block 32 and converge to form a connection port on its outer side. A connector is provided at the connection port and connected to an air pipe 35. The air pipe 35 is connected to a valve and a vacuum generating device. The short shaft 13 is fixed in the short shaft pressing groove 321 by suction.

[0043] Furthermore, the press-fitting drive component 4 is vertically fixed on the frame 1. The press-fitting drive component 4 can be a pneumatic cylinder or a hydraulic cylinder, etc., and a press-fitting head 41 is provided at the output end. The press-fitting head 41 moves up and down reciprocally. The long shaft limiting block 31 is also provided with a through hole in the middle for the press-fitting head 41 to pass through, such as... Figure 5 As shown, the long shaft limiting block 31 has a positioning groove for positioning the long shaft 12 inside. When pressed down, the long shaft limiting block 31 descends, and the top of the long shaft 12 extends into the positioning groove. Then, the pressing head 41 descends, passing through the long shaft limiting block 31 and the short shaft limiting block 32 to press the long shaft 12 and the short shaft 13 onto the valve body. After installation, as shown... Figure 6 As shown, both the pressing plate 3 and the pressing head 41 are equipped with position sensors to sense the position of the pressing plate 3 and the pressing head 41, ensuring accurate pressing position. The position sensors can be contact or non-contact types as needed.

[0044] Furthermore, the pressing plate 3 is connected to a horizontal moving assembly 5 and a vertical moving assembly 6. A connecting plate 11 is provided on the frame 1. Both the horizontal moving assembly 5 and the vertical moving assembly 6 are mounted on the connecting plate 11 and are used to drive the pressing plate 3 to move horizontally and vertically. Both the horizontal moving assembly 5 and the vertical moving assembly 6 include cylinders. A vertical guide rail is also installed on the connecting plate 11. A slider is provided on the guide rail, and a vertical moving plate 33 is provided on the slider. The cylinder drives the vertical moving plate 33 to move vertically. The vertical moving plate 33 is also equipped with... The horizontal guide rail and slider are arranged horizontally. The cylinder on the horizontal moving assembly 5 is horizontally fixed on the vertical moving plate 33. It also includes a horizontal moving plate 34 that moves along the horizontal guide rail. The output end of the cylinder is connected to the horizontal moving plate 34, which drives the horizontal moving plate 34 to move horizontally. The horizontal and vertical movement of the pressing plate 3 is realized by the extension and retraction of the two cylinders, so that the pressing head 41 is aligned with the long axis limit block 31 and the short axis limit block 32. The pressing of two shafts is completed by one pressing head 41, without the need for secondary handling, which effectively improves the pressing efficiency.

[0045] In some implementations, the detection component 2 includes a fixed plate 21, a detection camera 22, and a supplementary light 23. The detection camera 22 is mounted on the fixed plate 21, and the supplementary light 23 is mounted on the frame 1. The detection camera 22 is an industrial camera that captures images and transmits the images to a display screen mounted on the frame 1 for comparison with the correct image in the system. One end of the long axis 12 is smooth, and the other end may have numbers or letters. If there are characters at the end of the long axis 12 during shooting, the orientation of the long axis 12 is correct and the pressing operation continues. If there are no characters, the installation is reversed, prompting the staff to check.

[0046] In some implementation schemes, such as Figure 3 As shown, the positioning assembly includes a positioning plate 7, which is vertically positioned. The positioning plate 7 has a positioning block 71 and multiple positioning pins 75 fixed on it. The positioning block 71 is fixedly connected to the positioning plate 7 and has a positioning surface for receiving the valve body and contacting the outer surface of the valve body. The positioning plate 7 also has clamping components on both sides. The clamping components include a clamping shaft 72, which is connected to a telescopic rotary cylinder 73. The telescopic rotary cylinder 73 is fixed on both sides of the positioning plate 7 and is symmetrically arranged. The valve body to be pressed is received by the positioning block 71, limited by the positioning pins 75, and then clamped by the clamping components to ensure that the valve body is fixed in position. When the valve body is fixed, the positions of the long shaft 12 and the short shaft 13 are facing upward.

[0047] Furthermore, the positioning component is equipped with a movable plate 8, which is connected to a movable module. The movable module drives the positioning component to move between the detection component 2 and the pressing component. The movable module can be a lead screw motor module, which provides precise movement and convenient control.

[0048] In addition, the positioning plate 7 is also provided with a support column 74 for supporting the product. The support column 74 is connected to a support base on its lower side. The support base is fixed on the movable plate 8. The support column 74 is installed in the support base. When fixing the valve body, the top of the support column 74 contacts the valve body, which plays a good supporting role.

[0049] In the working process, the valve body is first manually placed on the positioning plate 7 and limited by the positioning pin 75 and the positioning block 71. The clamping shaft clamps the valve body, and the long shaft 12 is placed in the hole on the valve body where the long shaft 12 needs to be installed. Since the short shaft 13 is shorter, it is easy to be misaligned and damage the valve body during pressing. The short shaft 13 is placed in the short shaft limiting block 32 and fixed by suction. Then, the detection camera 22 takes a picture of the long shaft 12 to check whether the long shaft 12 is placed in the wrong direction. If it is placed correctly, the positioning component moves the valve body to the underside of the pressing component. First, the long shaft... The limiting block 31 descends to limit the top of the long shaft 12, and then the pressing head 41 descends to press the long shaft 12. Then the positioning component moves so that the position of the short shaft 13 to be pressed on the valve body is below the pressing head 41. At this time, the pressing plate 3 first moves horizontally to align the short shaft limiting block 32 with the valve body, and then descends. Then the pressing head 41 descends to press the short shaft 13. The pressed product is then manually removed for the next pressing. The pressing of two shafts is completed at one time, reducing handling, avoiding reverse pressing, ensuring assembly quality, and providing high assembly efficiency.

[0050] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
