Description

Technical Field

[0001] This utility model relates to the field of electronic throttle manufacturing equipment, specifically to a motor fixing and testing device for electronic throttles. Background Technology

[0002] The electronic throttle body houses a motor, which needs to be secured to the housing with screws. After securing, the motor's output current waveform must be tested to ensure it is correct. Traditional manufacturing equipment assembles the motor and housing in one workstation, and tests the motor in another. This design requires a secondary transfer of the assembled product, reducing work efficiency. Furthermore, the two different workstations have low integration, resulting in equipment redundancy and increased costs.

[0003] Therefore, it is necessary to provide a motor mounting and testing device for electronic throttle valves. Summary of the Invention

[0004] This utility model provides a motor fixing and testing device for electronic throttle valves, which effectively solves the problems of low efficiency and high cost in the assembly and testing of existing electronic throttle valve motors.

[0005] The technical solution adopted in this utility model is:

[0006] An electronic throttle motor fixing and testing device includes a frame, a quick-change fixture mounted on the frame, a screw-locking mechanism mounted on the frame, and a positioning testing mechanism mounted on the frame. The quick-change fixture includes a first guide rail mounted on the frame along the Y-axis, a fixture slidably mounted on the first guide rail, and a first cylinder mounted on the frame for driving the fixture to move along the first guide rail. The positioning testing mechanism includes a vertical plate mounted on the frame, a second guide rail and a third guide rail vertically mounted on the vertical plate and arranged along the Y-axis, a screw-locking guide assembly slidably mounted on the second guide rail, a motor testing assembly slidably mounted on the third guide rail, a second cylinder fixedly mounted on the frame for driving the screw-locking guide assembly to rise and fall, and a third cylinder for driving the motor testing assembly to rise and fall.

[0007] Furthermore, the screw-locking mechanism includes a screw-digging feeder mounted on the frame, a robotic arm mounted on the frame, and a screw gun mounted on the robotic arm.

[0008] Furthermore, the screw clamping guide includes a second frame body slidably mounted on the second guide rail, a clamping plate connected to the second frame body, a second knob screw connecting the second frame body and the clamping plate, a clamping head mounted on the lower end face of the clamping plate for clamping the motor, and a nail-passing hole mounted on the clamping plate.

[0009] Furthermore, the motor testing assembly includes a No. 3 frame body slidably mounted on the No. 3 guide rail, a No. 3 plate connected to the No. 3 frame body, a No. 3 knob screw connecting the No. 3 plate and the No. 3 frame body, a probe mounted on the No. 3 plate, and a tester mounted on the frame and electrically connected to the probe.

[0010] Furthermore, the quick-change tooling also includes a limiting component mounted on the frame for limiting the fixture. The limiting component includes a No. 4 cylinder mounted on the frame along the X direction and a limiting head mounted on the output end of the No. 4 cylinder. The side of the fixture is provided with two limiting grooves arranged along the Y direction to cooperate with the limiting head. When the fixture corresponds to the screw clamping guide assembly, the limiting component cooperates with one of the limiting grooves. When the fixture corresponds to the motor testing assembly, the limiting component cooperates with the other limiting groove.

[0011] Furthermore, the fixture includes an upper plate, a lower plate slidably mounted on a first guide rail, a stand mounted on the upper plate, a fifth guide rail vertically mounted on the stand, a vertical plate slidably mounted on the fifth guide rail, a fifth cylinder mounted on the upper plate for driving the vertical plate to rise and fall, several positioning pins mounted on the vertical plate, and a clamp for fixing the electronic throttle valve to the positioning pins.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] like Figure 1 As shown, the electronic throttle motor fixing and testing device provided in the embodiments of this application includes a frame 1, a quick-change fixture 2 mounted on the frame 1, a screw-locking mechanism 3 mounted on the frame 1, and a positioning testing mechanism 4 mounted on the frame 1. The quick-change fixture 2 includes a first guide rail 21 mounted on the frame 1 along the Y-axis, a fixture 22 slidably mounted on the first guide rail 21, and a first cylinder 23 mounted on the frame 1 for driving the fixture 22 to move along the first guide rail 21. The positioning testing mechanism 4 includes a vertical plate 41 mounted on the frame 1, a second guide rail 42 and a third guide rail 43 vertically mounted on the vertical plate 41 and arranged along the Y-axis, a screw-locking material guide assembly slidably mounted on the second guide rail 42, a motor testing assembly 45 slidably mounted on the third guide rail 43, a second cylinder 46 fixedly mounted on the frame 1 for driving the screw-locking material guide 44 to rise and fall, and a third cylinder 47 for driving the motor testing assembly 45 to rise and fall.

[0020] For ease of understanding, motor mounting refers to attaching the motor to the housing of the electronic throttle body with screws. Both before and after motor mounting are semi-finished products. From now on, the semi-finished products on the fixture will be referred to as finished products.

[0021] In actual use, when the output end of cylinder 23 extends, fixture 22 aligns with screw clamping guide 44. At this time, cylinder 46 drives screw clamping guide assembly to move down to the height of pressing the electronic throttle. Subsequently, screw clamping mechanism 3, with the cooperation of screw clamping guide assembly, clamps the screw onto the motor and housing of the electronic throttle. When the output end of cylinder 23 retracts, fixture 22 aligns with motor testing assembly 45. At this time, cylinder 47 drives motor testing assembly 45 to move down and connect with the motor to test whether the motor starts normally.

[0022] In the above design, by arranging the screw clamping guide 44 and the motor test assembly 45 along the Y direction, and by using the extension and retraction of the first cylinder 23 to make the fixture 22 correspond to the screw clamping guide 44 and the motor test assembly 45 respectively, the electronic throttle can quickly perform screw clamping and motor testing, improve work efficiency, save equipment volume, and thus reduce costs.

[0023] Specifically: such as Figure 1 As shown, the screw-locking mechanism 3 includes a screw-digging feeder 31 mounted on the frame 1, an assisting arm robot 32 mounted on the frame 1, and a screw gun 33 mounted on the assisting arm robot 32.

[0024] In actual use, the manual moving assistant arm robot 32 moves the screw gun 33 so that the screw gun 33 can pick up the screws in the nail digging feeder 31. Then, the manual moving assistant arm robot drives the screw gun 33 to move so that the screw gun 33 can move the picked-up screws to the screw fastening position to fasten the screws.

[0025] In the above design, the screw-locking mechanism 3 adopts a semi-automatic method, which can save costs while ensuring smooth screw-locking.

[0026] Specifically: such as Figure 2 As shown, the screw clamping guide 44 includes a second frame body 441 slidably mounted on the second guide rail 42, a clamping plate 442 connected to the second frame body 441, a second knob screw 443 connecting the second frame body 441 and the clamping plate 442, a clamping head 444 mounted on the lower end face of the clamping plate 442 for clamping the motor, and a nail hole 445 mounted on the clamping plate 442. The output end of the second cylinder 46 is connected to the second frame body 441.

[0027] In actual use, when the fixture 22 corresponds to the screw clamping guide 44, the second cylinder 46 drives the second frame body 441 to move down, so that the clamping head 444 clamps the product, and then the screw clamping mechanism 3 drives the screw to pass through the screw hole 445 to lock the screw.

[0028] In the above design, the screw clamping guide 44 can press and fix the product to be clamped using the clamping head 444, and can also guide the screw using the screw hole 445, facilitating the smooth clamping of the screw. When processing different models of products, different clamping plates 442 are replaced.

[0029] Specifically: such as Figure 2 As shown, the motor testing assembly 45 includes a frame body 451 slidably mounted on a guide rail 43, a plate 452 connected to the frame body 451, a knob screw 453 connecting the plate 452 and the frame body 451, a probe 454 mounted on the plate 452, and a tester mounted on the frame 1 and electrically connected to the probe 454. The tester may be an oscilloscope.

[0030] In actual use, the motor is powered on after the probe 454 contacts the motor, and the oscilloscope displays the current waveform after the motor is powered on. The user then judges whether the current waveform is qualified.

[0031] The above design enables rapid testing of the motor's power-on capability, and allows for the replacement of different No. 3 452 boards to adapt to different product models.

[0032] Specifically: such as Figure 1 and Figure 3 As shown, the quick-change tooling 2 also includes a limiting member 24 disposed on the frame 1 for limiting the fixture 22. The limiting member 24 includes a No. 4 cylinder disposed on the frame 1 along the X direction and a limiting head disposed at the output end of the No. 4 cylinder. The side of the fixture 22 is provided with two limiting grooves 220 arranged along the Y direction to cooperate with the limiting head. When the fixture 22 corresponds to the screw clamping guide assembly, the limiting member 24 cooperates with one of the limiting grooves 220. When the fixture 22 corresponds to the motor testing assembly 45, the limiting member 24 cooperates with the other limiting groove 220.

[0033] In actual use, when the product on fixture 22 is being tested for screw tightening or motor operation, cylinder No. 4 drives the limit head to extend, causing the limit head to lock into the corresponding limit groove 220.

[0034] In the above design, the stability of the fixture 22 can be improved by setting the limiting component 24 during operation, ensuring that the screw tightening and motor testing can be carried out smoothly.

[0035] Specifically, the fixture 22 includes an upper plate 221, a lower plate 222 slidably mounted on a first guide rail 21, a stand 223 mounted on the upper plate 221, a fifth guide rail 224 vertically mounted on the stand 223, a vertical plate 225 slidably mounted on the fifth guide rail 224, a fifth cylinder 226 mounted on the upper plate 221 for driving the vertical plate 225 to rise and fall, several positioning pins mounted on the vertical plate 225, and a clamp 227 for fixing the electronic throttle valve to the positioning pins. The lower plate 222 is provided with several grooves, and the lower end face of the upper plate 221 is provided with positioning posts that are adapted to the grooves.

[0036] In actual use, the electronic throttle is fixed to the positioning post using clamp 227. During motor testing, the vertical plate 225 can be raised using cylinder 226 (number 5), and the motor testing assembly 45 can be lowered using cylinder 47, bringing the motor into contact with the motor testing assembly 45. Alternatively, cylinder 226 can remain stationary, and cylinder 47 can be used to lower the motor testing assembly 45 to contact the motor. The purpose of cylinder 226 raising and lowering the vertical plate 225 is to accommodate the processing requirements of other workstations.

[0037] In the above design, the structural design and specific implementation of the fixture 22 facilitate the fixing of the product, and the upper plate 221 and above structure can be removed from the lower plate 222 and transferred to other workstations.

[0038] Specifically: such as Figure 3 As shown, the clamp 227 includes a sixth cylinder 271 mounted on a vertical plate 225, a positioning block 272 mounted on the vertical plate 225, a first rod 273 hinged to the positioning block 272, and a second rod 274 whose two ends are respectively hinged to one end of the first rod 273 and the output end of the sixth cylinder 271.

[0039] In actual use, when it is necessary to fix the product, the output end of cylinder 271 extends, causing rod 274 to rotate, which in turn drives rod 273 to rotate, thus pressing the product firmly.

[0040] In the above design, the structural design and specific implementation of the clamp 227 facilitate the continuous and stable clamping of the product using the power provided by air pressure.

[0041] In further detail, it should be understood that the above description is only a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
