Various components of the electronic throttle are installed in the electronic throttle body. The components of the electronic throttle include an impeller shaft and a throttle shaft. The electronic throttle body is provided with an impeller shaft mounting position and a throttle shaft mounting position. During installation, the impeller shaft needs to be pressed into the impeller shaft mounting position, and the throttle shaft needs to be pressed into the throttle shaft mounting position. The operation method in the prior art is as follows: the operator manually holds the electronic throttle body, and then manually presses the impeller shaft and the throttle shaft into the impeller shaft mounting position and the throttle shaft mounting position respectively.

[0020] The present invention provides a press-fitting device for processing an electronic throttle body shaft. It has the following beneficial effects:

[0021] 1. The press-fitting equipment for processing the electronic throttle body shaft has a lateral alignment component that clamps and centers the side position of the throttle body, and then the oppositely arranged limit components clamp and center the front and back positions of the throttle body, thereby achieving a stable clamping and limiting of the throttle body as a whole. Then, the electric turntable drives the fixing rod to rotate, and the fixing rod drives the square plate to rotate 90 degrees, so that the front position of the electronic throttle body is rotated to the position directly below the inner groove shell, and the impact guide mechanism transports the throttle shaft and the impeller shaft to the position directly above the electronic throttle body, and the hydraulic cylinder drives the inner groove shell to impact downward to press the shaft, which solves the problem that the existing fixture cannot be used to firmly clamp the electronic throttle body with an irregular appearance.

[0022] 2. The press-fitting equipment for processing the electronic throttle body shaft uses a linear guide to control the extension plate to approach the throttle body. Two rectangular frames approach the throttle body from the front and back sides respectively, thereby determining the press-fitting point of the throttle body. The four sides of the throttle body are clamped and limited, making the throttle shaft of the electronic throttle body and the impeller shaft more accurate when installed. The rubber edge is in direct contact with the surface of the throttle body, which increases the movement resistance of the throttle body surface and avoids the relative movement of the throttle body and the clamping structure when the electric turntable drives the throttle body to rotate, resulting in misalignment of the press-fitting point.

[0023] 3. The pressing equipment for processing the electronic throttle body shaft places the impeller shaft and the throttle shaft inside the guide slide assembly. When placing them, the baffle is used to limit the bottom ends of the impeller shaft and the throttle shaft, and the surfaces of the impeller shaft and the throttle shaft are clamped by a three-jaw chuck. Subsequently, the baffle is removed, and the second screw slide drives the guide slide to move to the position directly below the inner groove shell. The hydraulic cylinder controls the inner groove shell to impact downward, so that the impeller shaft and the throttle shaft are impacted to the pressing point of the electronic throttle body, which solves the problem that the installation of the impeller shaft and the throttle shaft are two separate processes, which requires the setting of two workers' operating stations.

[0024] 4. In the press-fitting equipment for processing the electronic throttle body shaft, the sphere is first rotated and installed in the inner groove position of the fixed cylinder, and then the two perforated shells are sleeved on the fixed cylinder in opposite directions, and the two fixed cylinders are fixed to realize the rotational installation of multiple spheres. After the impeller shaft and the throttle shaft are limited and guided, the three-jaw chuck clamps the surface of the impeller shaft and the throttle shaft. Then, during the press-fitting process, the impeller shaft and the throttle shaft are quickly pushed downward, and the sphere guides the shaft stably to prevent the impeller shaft and the throttle shaft from being deflected, and the press-fitting stability of the electronic throttle body is higher.

[0025] 5. The press-fitting equipment for processing the electronic throttle body shaft, after the electronic throttle body is positioned, the circular throttle structure is placed inside the U-shaped plate, the electromagnet is energized to attract the magnetic patch, the U-shaped plate clamps the surface of the throttle, and the lifter drives the U-shaped plate to move downward to the inside of the electronic throttle body. During press-fitting, the positions of the pulley and the throttle are reliably positioned, the rotation guides of multiple balls replace the sliding friction guides, the moving resistance of the pulley shaft and the throttle shaft is smaller, it is easier to press-fit and not easy to get stuck, so that the electronic throttle body press-fitting has higher accuracy.

[0042] When in use, the outer surface structure of the electronic throttle body is irregular, and the bottom of the electronic throttle body is placed on the top of the square plate 26. At this time, the position of the electronic throttle body is uncertain, and the mounting surfaces of the throttle shaft and the impeller shaft are parallel to the impact direction of the hydraulic cylinder 4. The lateral alignment component 28 clamps and centers the side position of the throttle body, and then the oppositely arranged limit components 29 clamp and center the front and back positions of the throttle body, thereby achieving a stable clamping and limiting of the throttle body as a whole.

[0045] When in use, the outer surface of the electronic throttle body has a special shape, but the four sides are generally rectangular structures. The first screw slide 281 is provided with two output ends, and the two output ends respectively control the clamping half pipe 282 and the slotted plate 283 to approach the throttle body. The structure of the clamping half pipe 282 and the slotted plate 283 is coordinated with the side position of the throttle body. The opposite movement of the clamping half pipe 282 and the slotted plate 283 pushes the throttle body to the position to be pressed. Subsequently, the linear guide 291 controls the extension plate 29 2 is close to the throttle body, and the two rectangular frames 293 are respectively approached from the front and back of the throttle body to determine the pressing point of the throttle body. The four sides of the throttle body are clamped and limited, so that the throttle shaft of the electronic throttle body and the pulley shaft are installed more accurately. The rubber edge 294 is in direct contact with the surface of the throttle body, which increases the movement resistance of the throttle body surface and avoids the throttle body and the clamping structure from moving relative to each other when the electric turntable 24 drives the throttle body to rotate, resulting in misalignment of the pressing point.

[0046] The third embodiment: Figure 3 , Figure 8 As shown, the output end of the electric turntable 24 is fixedly connected to a fixing rod 25, the end surface of the fixing rod 25 is fixedly connected to a square plate 26, a rectangular hole 27 is opened on the surface of the square plate 26 near the edge, and a lateral alignment component 28 and a limit component 29 are fixedly connected to the bottom of the square plate 26;

[0047] The clamping and positioning mechanism 2 further includes a support platform 21, which is fixedly mounted on the bottom of the inner side of the body 1, the inner side of the support platform 21 is fixedly connected to a docking platform 23, and the top of the support platform 21 is fixedly connected to an air nozzle 22;

[0049] When in use, the square plate 26 supports the electronic throttle body, the lateral alignment component 28 slides on the inner side of the rectangular hole 27, and the limit component 29 slides on the inner side of the rectangular hole 27, thereby clamping and limiting the side position and the front and back positions of the electronic throttle body respectively, and the electric turntable 24 drives the electronic throttle body to flip 90 degrees, so that the pressing point of the electronic throttle body is driven to the position directly below the inner tank shell 5, and the impeller shaft and the throttle shaft are placed inside the guide slide component 77.

Subsequently, the baffle is withdrawn, and the second screw slide 6 drives the guide rail 71 to move to the position directly below the inner groove shell 5. The hydraulic cylinder 4 controls the inner groove shell 5 to impact downward, and the plunger rod 73 moves downward to squeeze the spring 75, and the fixed plate 72 moves downward as a whole, so that the impeller shaft and the throttle shaft are impacted to the pressing point of the electronic throttle body, which solves the problem that the installation of the impeller shaft and the throttle shaft is two separate processes, and two workers need to set up operating stations.

There are two open hole shells 774.

[0051] When in use, the wheel shaft and the throttle shaft are slid through the two three-jaw chucks 76 respectively. At this time, the bottom of the bottom ring 772 contacts the baffle plate. The obstruction of the baffle plate limits the bottom of the wheel shaft and the throttle shaft. The surface of the ball 773 is in close contact with the surface of the wheel shaft and the throttle shaft. When the wheel shaft and the throttle shaft move downward, the ball 773 rotates on the inner side of the fixed cylinder 771, so that the wheel shaft and the throttle shaft are centered and guided.

There are two linear guide rails 291, which are respectively fixedly mounted on both sides of the first screw slide 281. The limit assembly 29 also includes an extension plate 292. The bottom end of the extension plate 292 is fixedly mounted on the output end of the linear guide rail 291. The top end of the extension plate 292 is fixedly connected to a rectangular frame 293. A rubber edge 294 is fixedly connected to the side of the rectangular frame 293 away from the extension plate 292.

[0055] The fixed cylinder 771 is fixedly installed at the bottom of the three-jaw chuck 76, and the bottom of the fixed cylinder 771 is fixedly connected with a bottom ring 772. The sliding guide assembly 77 also includes a sphere 773, and the sphere 773 is rotatably installed on the inner side of the fixed cylinder 771. The outer side of the fixed cylinder 771 is sleeved with an open hole shell 774, and there are two open hole shells 774.

[0056] When in use, the support platform 21 supports multiple air nozzles 22 near the top of the square plate 26. The air nozzles 22 allow the gas to be compressed and then impacted to the top of the square plate 26, so that impurities on the surface of the square plate 26 are blown away, preventing the impurities from being retained and causing the press-fit position of the electronic throttle body to deviate. The device uses a rectangular frame 293 to clamp the front position of the electronic throttle body. The rectangular structure allows the wheel to be pressed and fixed without interfering with the press-fit point. When the electronic throttle body is positioned, the circular structure The throttle is placed inside the U-shaped plate 286, and the electromagnet 287 is energized to attract the magnetic patch. The U-shaped plate 286 clamps the surface of the throttle, and the lifter 284 drives the U-shaped plate 286 to move downward to the inside of the electronic throttle body. During press-fitting, the positions of the pulley and the throttle are reliably positioned, and the rotation guides of the multiple balls 773 replace the sliding friction guides. The movement resistance of the pulley shaft and the throttle shaft is smaller, which makes it easier to press-fit without getting stuck, thereby making the electronic throttle body press-fitting more accurate.
