Description

Technical Field

[0001] This utility model relates to the field of electronic throttle body manufacturing, specifically to an assembly device for an electronic throttle body bearing assembly. Background Technology

[0002] The electronic throttle body requires a hinge to be installed on its housing. The hinge rotates to open and close the valve plate, thus regulating flow. The hinge and housing are connected by a bearing, with a C-ring on the hinge for bearing positioning. In traditional assembly, the shaft pressing mechanism and the bearing pressing mechanism are separate, resulting in a complex structure. Furthermore, during assembly, the lower end of the shaft is typically blocked by a fixed plug at the lower end of the housing shaft hole. However, this plug, being a fixed support structure, cannot provide reverse lifting force during press-fitting. This causes the shaft to easily shift or tilt when the bearing is pressed in after the plug deforms, affecting assembly accuracy and potentially leading to damage to the bearing or shaft due to uneven stress.

[0003] Therefore, it is necessary to provide an assembly device for an electronic throttle bearing assembly. Summary of the Invention

[0022] 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.

[0023] like Figure 1 As shown, the electronic throttle bearing assembly assembly device provided in the embodiments of this application includes a frame 1, a material box assembly 2 disposed on the frame 1, a tooling 3 disposed on the frame 1, and a pressing mechanism 4 disposed on the frame 1 above the tooling 3, and a top shaft mechanism 5 disposed on the frame 1 for use below the tooling 3. The pressing mechanism 4 includes a bracket 41 disposed on the frame 1, a lifting frame 42 disposed on the bracket 41, a driving assembly 43 disposed on the bracket 41 for driving the lifting frame 42 to move up and down, and a material picking and pressing assembly 44 disposed at the lower end of the lifting frame 42. The top shaft mechanism 5 and the material picking and pressing assembly 44 abut against the lower end and upper end of the shaft 300 of the bearing assembly, respectively.

[0024] The material box assembly 2 contains a C-type card 400, a shaft 300, and a bearing 100. For example... Figure 6 As shown, the bearing assembly is a structure consisting of shaft 300, bearing 100, and C-type clip 400. The electronic throttle valve is a semi-finished product with a housing; for ease of understanding, it will be referred to as body 200 below. Body 200 and tooling 3 are provided with holes, allowing the top shaft mechanism 5 to abut against the lower end of shaft 300 through the holes. This application uses a PLC control system to control tooling 3, pressing mechanism 4, and top shaft mechanism 5.

[0025] In actual use, the main body 200 is placed and fixed on the tooling 3. The bearing 100 is manually placed in the material handling and pressing assembly 44, and then the assembled C-type clip 400 and shaft 300 are placed in the main body 200, so that the bearing 100 and shaft 300 are concentric. Subsequently, the drive assembly 43 drives the material handling and pressing assembly 44 to descend, and the top shaft mechanism 5 moves upward, pressing the shaft 300 and C-type clip 400 into the main body 200. The lower end of the shaft 300 abuts against the top shaft mechanism 5, and at the same time, the bearing 100 is pressed into the shaft 300 and into the product.

[0026] In the above design, the bearing 100 to be assembled is manually placed in the material handling and pressing assembly 44, and the material handling and pressing assembly 44 presses the bearing 100 into the shaft 300 inside the body 200. At the same time, the material handling and pressing assembly 44 and the top shaft mechanism 5 apply pressure to the upper and lower ends of the shaft 300 respectively, so as to ensure stability after the shaft 300 and the body 200 are assembled to the predetermined position, which facilitates the assembly of the bearing 100 and the shaft 300. It can effectively realize the rapid assembly of the body 200, the shaft 300, the C-type clip 400 and the bearing 100.

[0027] Specifically: such as Figure 2 and Figure 3 As shown, the material feeding and pressing assembly 44 includes a floating connector 401 disposed at the lower end of the lifting frame 42, a flange 402 disposed at the lower end of the floating connector 401, a pressure sensor 403 disposed at the lower end face of the flange 402, a first connecting plate 404 disposed at the lower end face of the pressure sensor 403, a first sleeve 405 disposed on the first connecting plate 404, a plurality of first pins 300 406 slidably disposed on the first connecting plate 404, a second connecting plate 407 fixedly connected to the lower end of the first pins 300 406, a second sleeve 408 disposed at the upper end face of the second connecting plate 407 and a third sleeve 409 disposed at the lower end face of the second connecting plate 407, and a sleeve for... A first spring 410 is mounted on the second sleeve 408 and its two ends abut against the first connecting plate 404 and the second connecting plate 407 respectively. A hollow shaft 411 is mounted on the first connecting plate 404 and located inside the first sleeve 405. A groove is mounted inside the hollow shaft 411. A pressure rod 412 is slidably mounted inside the hollow shaft 411. A second spring 413 is mounted inside the hollow shaft 411. The two ends of the second spring 413 abut against the lower end face of the pressure sensor 403 and the upper end face of the pressure rod 412 respectively. The lower end of the hollow shaft 411 extends into the third sleeve 409. A spherical plunger 414 extending radially is mounted on the third sleeve 409.

[0028] The lower end of the pressure rod 412 is tapered, and the upper end of the shaft 300 has a tapered groove that mates with the tapered shape. Pressing the lower end of the pressure rod 412 into the tapered groove enables concentric positioning of the shaft 300. The upper end of the pressure rod 412 is located above the retaining groove, which prevents the pressure rod 412 from disengaging from the hollow shaft 411.

[0029] In actual use, the bearing 100 is manually inserted into the third sleeve 409, so that the bearing 100 compresses the ball head of the spherical plunger 414 and is positioned above the spherical plunger 414. Then, the spherical bearing 100 resets and limits the lower end of the bearing. Subsequently, the material feeding and pressing assembly 44 descends, so that the lower end of the third sleeve 409 abuts against the body 200. The first pin 300 406 moves upward relative to the first connecting plate 404, the first spring 410 is compressed, the pressure rod 412 presses down on the shaft 300, and the second spring 413 is compressed. As the downward movement continues, the shaft 300 is fully pressed into the predetermined position of the body 200 and limited by the top shaft mechanism 5. The first sleeve 405 presses the bearing 100 down from above along the axial direction of the shaft 300. After the bearing 100 pushes the spherical plunger 414 outward, it is fully assembled with the shaft 300, so that the bearing 100 is pressed into the shaft 300 to form an interference fit. Once the pressure sensor 403 detects that the pressure is within the acceptable range, the drive assembly 43 then drives the material feeding and pressing assembly 44 to move upward and reset.

[0030] In the above design, the structural design and specific implementation of the material feeding and pressing component 44 can effectively realize the pressing of the interference fit between the bearing and the shaft 300. By sensing the combined force of the downward drive component 43 and the upward force of the top shaft 300 component through the pressure sensor 403, the pressure on the bearing and the shaft 300 is monitored, thereby improving the accuracy of the bearing assembly and the body 200.

[0031] Specifically: such as Figure 1 As shown, the third sleeve 409 is also provided with a radial through hole located above the spherical plunger 414, and the bracket 41 is provided with a photoelectric switch 45 corresponding to the radial through hole.

[0032] In actual use, after the bearing 100 is manually placed inside the No. 3 sleeve 409, the signal from the photoelectric switch 45 detects the presence of the bearing 100 through the radial through hole before subsequent clamping and assembly can be carried out.

[0033] In the above design, the photoelectric switch automatically detects whether the bearing is in place, which can ensure that the subsequent assembly of bearing 100 and shaft 300 will not reduce the assembly accuracy due to incorrect bearing 100 position.

[0034] Specifically: such as Figure 1 and Figure 4 As shown, the top shaft mechanism 5 includes a mounting plate 51 mounted on the frame 1, a first linear guide rail 52 vertically mounted on the mounting plate 51, a sliding plate 53 slidably mounted on the first linear guide rail 52, a linear module 54 mounted on the mounting plate 51 for driving the sliding plate 53 to rise and fall, and a top material shaft 55 mounted on the sliding plate 53. The tooling 3 is provided with a clearance hole for the top material shaft 55 to be positioned.

[0035] In actual use, when it is necessary to hold the lower end of shaft 300 in place, the linear module 54 drives the sliding plate 53 to move upward along the first linear guide rail 52, so that the top material shaft 55 moves upward along the sliding plate 53. The top material shaft 55 passes through the clearance hole and enters the hole of the body 200 to abut against the lower end of shaft 300.

[0036] In the above design, the structural design and specific implementation of the top shaft mechanism 5 can effectively support the lower end of the shaft 300 during the assembly process, preventing deviations in the assembly of the shaft 300 and the body 200.

[0037] Specifically: such as Figure 5 As shown, the tooling 3 includes a support plate 301, a fixed base 302 fixedly mounted on the support plate 301, a second linear guide rail 303 vertically mounted on the fixed base 302, a vertical plate 304 slidably mounted on the second linear guide rail 303 and having a horizontal through hole, a support block 305 mounted on the vertical plate 304, a clamping member 306 mounted on the vertical plate 304, a guide block 307 mounted at the lower end of the support block 305, and a clamping member 306 mounted on the fixed base. The support shaft 300308, which is oriented in the normal direction and passes through the horizontal through hole, the horizontal plate 309, which is set on the vertical plate 304, and the third spring 310, which is respectively abutted against the lower end face of the horizontal plate 309 and the upper end face of the support plate 301. The support block 305 is provided with a first vertical through hole, and the guide block 307 is provided with a second vertical through hole corresponding to the first vertical through hole. The top material shaft 55 is slidably connected to the first vertical through hole and the second vertical through hole.

[0038] It should be noted that the main body 200 has a cavity, with an air inlet and an air outlet on both sides of the cavity. The support shaft 300308 extends into the cavity. The clamping member 306 includes a cylinder, a fixed block, and a connecting rod mounted on the fixed block. The cylinder drives the connecting rod to rotate around the fixed block, thereby opening and closing the clamping member 306, thus realizing the picking up, placing, and clamping of the product.

[0039] In actual use, the body 200 is placed horizontally on the support block 305, allowing the support shaft 300308 to extend into the cavity. The body 200 is then clamped by the clamping member 306. When assembling the shaft 300, bearing 100, and body 200, the body 200 is subjected to pressure, causing the support block 305 to move downwards, compressing the third spring 310 until the support shaft 300308 contacts the inner wall of the cavity. During the assembly of the shaft 300 and bearing 100, the ejector shaft 55 passes through the first and second vertical through holes into the hole in the housing, supporting the lower end of the shaft 300 within the hole.

[0040] In the above design, the structural design and specific implementation of the tooling 3 facilitate the effective fixing of the body 200, thereby facilitating the assembly of the body 200 and the bearing assembly.

[0041] Specifically: such as Figure 1 As shown, the tooling 3 also includes several quick clamps 311 mounted on the frame 1 for clamping the support plate 301. The frame 1 is also provided with positioning posts, and the support plate 301 is provided with positioning holes that cooperate with the positioning posts.

[0042] In actual use, the tooling 3 parts other than the quick clamp 311 are transferred to achieve quick change of tooling 3. After tooling 3 is placed on the frame 1 and positioned with the positioning post, the carrier plate 301 is fixed on the frame 1 by the quick clamp 311.

[0043] In the above design, the structural design of tooling 3 facilitates quick replacement of tooling 3, thereby improving production efficiency.

[0044] Specifically: such as Figure 7 As shown, the driving component 43 is an electric cylinder. The lifting frame 42 includes several linear bearings 421 vertically mounted on the support 41, several guide posts 422 slidably mounted on the linear bearings 421, and a connecting plate 423 connecting the lower ends of the guide posts 422. The material feeding and pressing component 44 is located on the lower end of the connecting plate 423. A connecting rod is provided between the upper ends of two adjacent guide posts 422. The output end of the electric cylinder is connected to the upper end of the connecting plate 423.

[0045] In actual use, the connecting plate 423 is raised and lowered by an electric cylinder, which in turn causes the connecting plate 423 to raise and lower the guide column 422.

[0046] In the above design, the structural design and specific implementation of the lifting clamp and drive assembly 43 can effectively realize the lifting drive of the material feeding and pressing assembly 44.

[0047] 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.
