[0020] 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.
[0021] like Figure 1 and Figure 2As shown, the electronic throttle body hot riveting device provided in the embodiments of this application includes a frame 1, a feeding mechanism 2 mounted on the frame 1, and a hot riveting mechanism 3 mounted on the frame 1 for hot riveting the product in the feeding mechanism 2. The hot riveting mechanism 3 includes a bracket 31 mounted on the frame 1, a lifting frame 32 slidably mounted on the bracket 31, a drive assembly 33 mounted on the bracket 31 for driving the lifting frame 32 to rise and fall, and a plurality of hot riveting evaluation components 34 mounted at the lower end of the lifting frame 32. The hot riveting evaluation components 34 include... It includes a connecting block 341 fixedly mounted at the lower end of the lifting frame 32, a first linear guide rail 342 vertically mounted on the connecting block 341, a hot riveting gun 343 slidably mounted on the first linear guide rail 342, a first cylinder 344 mounted on the connecting block 341 for driving the hot riveting gun 343 to slide along the first linear guide rail 342, a displacement sensor 345 mounted on the connecting block 341, a vertical elastic pressure member 346 mounted on the connecting block 341, and a pressure sensor 347 mounted on the hot riveting gun 343 that cooperates with the vertical elastic pressure member 346.
[0022] It should be noted that, as Figure 4 As shown, this application involves hot riveting the body (housing 100, valve plate, and gear) of an electronic throttle valve to a magnet 200, specifically hot riveting the gear to the magnet 200. The body containing the magnet 200 is referred to as the product. In this application, the hot riveting mechanism 3 and the feeding mechanism 2 are controlled by a PLC control system.
[0023] In actual use, the body containing the magnet 200 is placed on the feeding mechanism 2, which then transports the product to the hot riveting position. Subsequently, the driving component 33 drives the lifting frame 32 downwards, causing the lifting frame 32 to move the hot riveting evaluation component 34 downwards to perform hot riveting on the magnet 200. During hot riveting, the first cylinder 344 drives the hot riveting gun 343 downwards along the first linear guide rail 342, causing the hot riveting gun 343 to move downwards synchronously. During the downward movement of the hot riveting gun 343 and during the hot riveting process, the vertical elastic pressure member 346 generates elastic tension, gradually reducing the pressure on the pressure sensor 347. The displacement sensor 345 senses an increase in the distance from the hot riveting gun 343. Riveting is completed when both the pressure sensor 347 and the displacement sensor 345 sense the preset values. The product is then transported out of the riveting position by the feeding mechanism 2 for manual unloading.
[0024] In the above design, by setting up a driving component 33 to drive multiple hot riveting evaluation components 34 to simultaneously perform hot riveting on multiple hot riveting points of the product, the problem of uneven heat deformation of the magnet 200 caused by point riveting can be effectively solved. By using displacement sensor 345 and pressure sensor 347 to monitor the hot riveting, the hot riveting process can be monitored from two directions: the displacement of the hot riveting gun 343 and the force during hot riveting, thereby improving the accuracy of hot riveting.
[0025] Specifically: such as Figure 3 As shown, the vertical elastic pressure member 346 includes a guide post 461 slidably disposed on the connecting block 341, a pressure head 462 fixedly disposed on the lower end face of the guide post 461, and a spring 463 sleeved on the guide post 461. The two ends of the spring 463 abut against the upper end face of the pressure head 462 and the lower end face of the connecting block 341, respectively. The lower end face of the pressure head 462 abuts against the sensing end of the pressure sensor 347.
[0026] In actual use, as the hot riveting gun 343 moves downward, the guide post 461 moves downward, the spring 463 stretches, and the pressure head 462 remains in contact with the sensing end of the pressure sensor 347. The pressure on the pressure sensor 347 gradually decreases during the stretching of the spring 463.
[0027] In the above design, the structural design and specific implementation of the vertical elastic element can effectively achieve continuous contact with the pressure sensor 347, enabling the pressure sensor 347 to sense pressure.
[0028] Specifically: such as Figure 2 As shown, the lifting frame 32 includes several linear bearings 321 vertically arranged on the support 31, several lifting shafts 322 respectively sleeved in the linear bearings 321, a connecting frame 323 connecting the lower ends of the lifting shafts 322, a connecting plate 324 connecting the upper ends of two adjacent lifting shafts 322 arranged along the Y direction, and a proximity switch 325 arranged on the connecting plate 324. The driving component 33 is a second cylinder, and the output end of the second cylinder is fixedly connected to the connecting frame 323. The hot riveting evaluation component 34 is arranged on the lower end face of the connecting frame 323.
[0029] In actual use, the output end of cylinder number two extends to drive the connecting frame 323 downward, causing the connecting frame 323 to drive the lifting shaft 322 to slide downward within the linear bearing 321, so that the hot riveting evaluation component 34 connected to the lower end of the connecting frame 323 performs hot riveting on the product. After the hot riveting is completed, the output end of cylinder number two drives the connecting frame 323 upward, causing the connecting frame 323 to drive the lifting shaft 322 to reset.
[0030] In the above design, the structural design of the lifting frame 32 and its specific implementation facilitate the stable lifting of the hot riveting evaluation component 34 through the cooperation of the lifting shaft 322 and the linear bearing 321. The distance between the lifting shaft 322 and the upper surface of the bracket 31 during the lifting process is sensed by the proximity switch 325 to detect whether the movement of the lifting frame 32 is in place.
[0031] Specifically: such as Figure 1As shown, the feeding mechanism 2 includes a second linear guide rail 21 arranged along the Y-axis on the frame 1, a support fixture 22 slidably arranged on the second linear guide rail 21, and a linear module 23 fixedly arranged on the frame 1 for driving the support fixture 22 to slide along the second linear guide rail 21.
[0032] In actual use, the product is supported by the support fixture 22, and then the linear module 23 drives the support fixture 22 to move to the predetermined hot riveting position for hot riveting. After the hot riveting is completed, the linear module 23 drives the support fixture 22 to move out of the hot riveting position.
[0033] In the above design, the structural design and specific implementation of the feeding mechanism 2 can effectively achieve stable delivery of the product.
[0034] Specifically: such as Figure 4 As shown, the support fixture 22 includes a base plate 221 slidably connected to the second linear guide rail 21, a vertical plate 223 disposed on the base plate 221, a support block 224 disposed on one side of the vertical plate 223, a support shaft 225 disposed on the vertical plate 223 for supporting the product, and a number of clamping components disposed on the vertical plate 223 for clamping the product. The clamping components include a positioning block 227 disposed on the vertical plate 223, a rotating pressure rod 228 hinged to the positioning block 227, a third cylinder 229 disposed on the vertical plate 223, and a rotating block 226 whose two ends are respectively hinged to the output end of the third cylinder 229 and one end of the rotating pressure rod 228. The rotating pressure rod 228 is used to clamp the product.
[0035] During actual product loading, the clamping device opens, and the lower end of the product is supported by the support block 224. The support shaft 225 supports the through hole of the housing. Then, the housing is fixed by the clamping device. The clamping process is as follows: the output end of the third cylinder 229 extends, causing the rotating rod to rotate. The rotating rod drives one end of the rotating pressure rod 228 to rotate around the hinge point with the positioning block 227, so that the other end of the rotating pressure rod 228 presses the housing and clamps the product with the vertical plate 223.
[0036] In the above design, the structural design and specific implementation of the support fixture 22 can effectively fix the product.
[0037] Specifically: such as Figure 1 and Figure 5 As shown, the frame 1 is also equipped with a barcode scanning mechanism 4. The barcode scanning mechanism 4 includes a support rod 41 mounted on the frame 1, a first rod 42 extending along the X-axis, a first clamp 43 connecting the support rod 41 and the first rod 42, a second rod 44 extending along the Y-axis, a second clamp 45 connecting the first rod 42 and the second rod 44, a mounting plate 46 mounted on the second rod 44, and a barcode scanner 47 mounted on the mounting plate 46.
[0038] In actual use, by adjusting the position of clamp 43 on rod 42 and support rod 41, the height and X-axis position of barcode scanner 47 are adjusted. By adjusting the position of clamp 45 on rod 44, the Y-axis position of barcode scanner 47 is adjusted. The barcode scanner 47 then scans the QR code on the surface of the hot-riveted product.
[0039] In the above design, the structural design and specific implementation of the scanning mechanism 4 can effectively realize the scanning of the product to record the product's processing information, which facilitates product traceability.
[0040] Specifically: such as Figure 1 As shown, a defective product storage box 5 is also provided on the frame 1.
[0041] In the above design, the defective product storage box 5 stores products that fail the heat riveting test.
[0042] 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.
