Description

Technical Field

[0001] This utility model relates to the field of electronic throttle technology, specifically to an electronic throttle assembly and testing device. Background Technology

[0002] With the development of automotive technology, electronic throttle bodies have been increasingly widely used, 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. In existing technologies, electronic throttle bodies use a valve shaft to control valve opening and closing, with gears welded onto it. The rotation of these gears is driven by a motor. During installation, the gears are welded first, followed by motor installation, and then the gear welds and motor voltage are inspected. This process involves multiple steps, is cumbersome, requires multiple handling operations, and is time-consuming and labor-intensive. There is an urgent need for an integrated device that can perform weld inspection, motor installation, and inspection. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides electronic throttle assembly and testing equipment, which realizes the inspection of electronic throttle welds, motor installation and testing, and combines multiple installation and testing processes to improve production efficiency and save costs.

[0004] Specifically, this utility model discloses an electronic throttle body assembly and testing device, comprising:

[0009] The advantages of adopting the above technical solution are that it enables the inspection of weld seams of electronic throttle valves, motor installation and motor inspection, and combines multiple installation and inspection processes, reducing product handling, improving processing efficiency and saving costs.

[0010] Furthermore, the fixing base includes a side plate, the side plate is provided with a plurality of fixing blocks for receiving the product, and the side plate is also provided with a plurality of positioning posts.

[0011] The advantage of adopting the above technical solution is that the fixing block on the side plate plays a supporting role, while the positioning column plays a positioning role.

[0012] Furthermore, a connecting plate is connected to the top of the detection head, and the connecting plate is connected to a horizontal moving module and a vertical moving module. The horizontal moving module is mounted on the frame and drives the vertical moving module to move.

[0013] The advantage of adopting the above technical solution is that when testing is required, the detection head moves and descends to perform ventilation testing.

[0014] Furthermore, the detection head has an internal cavity and an air inlet on its side, which communicates with the cavity inside the detection head. An air inlet pipe is connected to the outside of the air inlet, and a flow meter is installed on the air inlet pipe.

[0022] Furthermore, the side plate is provided with a clamping assembly, including a clamping block and a cylinder, wherein the clamping block is connected to the cylinder and the cylinder is mounted on the side plate.

[0023] The advantage of adopting the above technical solution is that the clamping block is used to press the product firmly onto the side plate, so that the entire product is fixed and will not move during assembly, thus ensuring the installation quality.

[0024] Furthermore, the frame is also provided with a receiving platform, the receiving platform is provided with a receiving seat, and the receiving seat is provided with a limiting cavity for limiting the motor.

Detailed Implementation

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

[0037] like Figure 1-5 As shown, this utility model discloses an electronic throttle assembly and testing device, comprising:

[0038] The frame 1 is equipped with a mounting base 2 for fixing the product;

[0039] The weld inspection device includes an inspection head 3, used for air-flushing inspection of weld quality, the location of which is as follows: Figure 5 Point A in the diagram indicates the welding position between the electronic throttle valve shaft and gear 12. Gear 12 should be a sector gear.

[0040] Motor mounting device for assembling motor 11;

[0041] The motor testing device performs power-on testing on the installed motor 11.

[0042] The advantages of adopting the above technical solution are that it realizes the inspection of the weld of the electronic throttle valve, the installation and inspection of the motor 11, and combines multiple installation and inspection processes, reducing product handling, improving processing efficiency, and saving costs.

[0043] Furthermore, the mounting base 2 includes a side plate 21, which is provided with multiple fixing blocks 22 for receiving the product. The side plate 21 is also provided with multiple positioning posts 23. The side plate 21 is vertically fixed to the frame 1. The fixing blocks 22 are fixed to the side of the side plate 21. There are two fixing blocks 22. The upper surface of the fixing blocks 22 is provided with a curved surface that matches the shape of the product for receiving the product. The positioning posts 23 are fixed to the side plate 21 by locking. The product is provided with positioning holes. When fixed, the installation position of the motor 11 on the product faces upward, and the welding position of the gear 12 and the valve shaft also faces upward, which facilitates weld inspection and motor 11 installation.

[0044] In addition, the side plate 21 is provided with a pressing assembly, including a pressing block 8 and a cylinder 81. The pressing block 8 is connected to the cylinder 81, which is mounted on the side plate 21. The cylinders 81 are symmetrically mounted on the fixed base 2. When the pressing cylinder extends, there is enough space between it and the side to pick up the product. When it retracts, the pressing block contacts the product and presses the product onto the side plate 21.

[0045] The advantage of adopting the above technical solution is that the clamping block 8 is used to press the product onto the side plate 21, so that the entire product is fixed and secure and will not move during assembly, thus ensuring installation quality.

[0046] Furthermore, a connecting plate 31 is connected to the top of the detection head 3. The connecting plate 31 is connected to a horizontal moving module 32 and a vertical moving module 33. The horizontal moving module 32 is mounted on the frame 1 and drives the vertical moving module 33 to move. The horizontal moving module 32 can be a horizontally mounted cylinder. A horizontally mounted guide rail is mounted on the frame 1, and a sliding plate 35 is mounted on the guide rail. The horizontal cylinder is fixed on the frame 1, and its output end is connected to the sliding plate 35, driving the sliding plate 35 to move. The vertical moving module 33 includes a cylinder that is vertically fixed on the sliding plate 35. Its extended end is connected to the detection head 3, driving the detection head 3 to descend. The bottom of the detection head 3 contacts the surface of the gear 12.

[0047] Furthermore, the detection head 3 has a cylindrical cavity 31 inside, which is used to accommodate the weld seam connecting the product valve shaft and the gear 12. The detection head 3 has an air inlet on its side, which is connected to the cavity 31 inside the detection head 3. An air inlet pipe is connected to the outside of the air inlet, and a flow meter 34 is installed on the air inlet pipe. The air inlet pipe is connected to an air source and a valve for air supply. The flow meter 34 is a gas flow meter. A sealing ring is installed at the bottom of the detection head 3. During the test, the detection head 3 is connected to the gear 12. At this time, the welding position of the gear 12 is located inside the detection head. The air inlet pipe is filled with air. If the displayed value of the flow meter 34 is within the set range, it means that there is no air leakage in the weld seam, indicating that the gear 12 is welded well.

[0048] In some implementations, the motor mounting device includes a motor feeding assembly and a screw-locking assembly. The motor feeding assembly includes a feeding robot 4 mounted on the frame 1 for transferring the motor 11 to the mounting location. The screw-locking assembly includes an automatic torque wrench 6 for locking the motor 11 to the product. The feeding robot 4 is equipped with grippers at its end, which pneumatically grip the motor 11 and then place the motor 11 in the product motor 11 mounting position. The feeding robot 4 can be three-axis, four-axis, etc., and can move and extend. The entire structure and working principle of the feeding robot 4 are existing technologies. The grippers and their control methods, working principles, etc., are also existing technologies and will not be described in detail here. The automatic torque wrench 6 is used to automatically tighten the screws on the motor, fixing the motor to the valve body. The screws for installing the motor are pre-locked in the motor's mounting holes during loading and are not yet tightened. During installation, they only need to be tightened using the automatic torque wrench. At the same time, the automatic torque wrench is also connected to a movable module, which can be a lead screw motor module to achieve multiple locking points. The automatic torque wrench 6 also has a bracket for installation. The entire structure of the automatic torque wrench is existing technology, and its specific structure will not be described here.

[0049] Furthermore, the motor testing device includes a probe mounting plate 7 and testing probes 71. The upper side of the probe mounting plate 7 has a sliding cylinder that drives the probe mounting plate 7 to move up and down. Two testing probes 71 are mounted on the probe mounting plate 7 and are respectively connected to the positive and negative terminals of the motor 11. The upper end of the testing probe 71 is connected to a wire, which is connected to an output power supply to provide power. It also has a display panel that can display the voltage and current. If the displayed voltage and current are within the normal range, it indicates that the motor 11 can work normally.

[0050] Furthermore, the frame 1 is also provided with a receiving platform 9, and the receiving platform 9 is provided with a receiving seat 91. The receiving seat 91 is provided with a limiting cavity for limiting the motor 11. The limiting cavity is provided to straighten the position of the motor 11 so that the positive and negative poles of the motor 11 face upward and are in the correct position, which facilitates the gripping and installation by the robot arm.

[0051] In some implementations, a rotating plate 92 is provided at the bottom of the fixed base 2. The rotating plate 92 is rotatably mounted on the frame 1, which drives the fixed base 2 to move. The bottom of the rotating plate 92 is provided with a bearing and a rotating spindle. The rotating spindle is driven by a motor to rotate, so that the entire rotating plate 92 rotates. A partition plate 5 is provided on the frame 1. The weld detection device and the feeding robot 4 for the feeding motor are located on the front of the partition plate 5. The motor detection device and the automatic torque wrench 6 are installed on the rear side and are driven to rotate by the rotating plate 92, which reduces the space occupied by the entire equipment.

[0052] The working process is as follows: First, the operator places the product to be installed on the fixed base 2 and secures it. Then, the clamping block 8 is used to tighten it. Next, the operator places the motor 11 on the receiving base 91. The loading robot 4 picks up the motor 11 and places it on the product's motor fixing position. At this time, the detection head 3 descends and contacts the side of the gear 12 on the product. Air is introduced through the air inlet pipe, and the flow meter detects the air volume and flow rate changes to judge the welding quality of the weld. Then, the rotating plate 92 rotates to the rear, and the automatic torque wrench 6 locks the motor 11 to the product for fixation. Then, the detection probe 71 descends to perform power-on testing. After the test is completed, the rotating plate 92 rotates, and the operator removes the completed product and places the product to be processed in for further assembly. The entire equipment control process can be achieved by sensing the position of the product and various mechanisms through multiple sensors, such as photoelectric switches and ultrasonic sensors, or by controlling each action through manual buttons. This application allows one machine to complete weld inspection, motor assembly, and motor inspection, improving assembly efficiency and ensuring a high yield rate.

[0053] 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.
