Description
Technical Field
[0001] This utility model relates to the field of throttle assembly, specifically to an electronic throttle pin and bushing pressing device. Background Technology
[0002] An electronic throttle valve is a controllable valve. It requires the assembly of a pin and bushing onto the housing. The pin and bushing are assembled in different positions, necessitating a two-stage process. Traditional assembly methods use a fixture to separately secure the housing during bushing insertion. However, this method can easily cause the outer frame to loosen under pressure from the fixture, leading to housing damage, reduced yield, and decreased assembly efficiency.

Detailed Implementation
[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 As shown, the electronic throttle pin and bushing pressing device provided in the embodiments of this application includes a frame 1, a pin pressing mechanism and a bushing pressing mechanism disposed on the frame 1. The pin pressing mechanism includes a first fixture 2 disposed on the frame 1 and a first pressing component 3 disposed on the frame 1. The bushing pressing mechanism includes a second fixture 4 disposed on the frame 1, a second pressing component 5 disposed on the frame 1 and a top material component 6 disposed on the frame 1. The top material component 6 is vertically corresponding to the pressing component.
[0022] In actual use, the outer casing 100 is first fixed to fixture 2. Then, the pin is manually pre-installed on the outer casing 100. Subsequently, the first pressing component 3 presses down the pre-installed pin, thus assembling the pin with the outer casing 100. Then, the outer casing 100 is transferred to fixture 4 and fixed. The bushing is manually pre-installed on the outer casing 100. The outer casing 100 is supported by the top material component 6. Then, the second pressing component 5 presses down the bushing, thus completing the assembly of the bushing with the outer casing 100.
[0023] In the above design, the throttle body housing 100 can be quickly assembled with the pin and bushing. Furthermore, the top material assembly 6 can provide a lifting force to the housing 100 during the bushing assembly process in the direction of the second pressing assembly 5, preventing the housing 100 from becoming loose and affecting the bushing pressing, thereby improving the accuracy of the bushing pressing.
[0024] Specifically: such as Figure 2 As shown, the first fixture 2 includes a first fixing plate 21 fixedly mounted on the upper surface of the frame 1, several first quick clamps 22 mounted on the first fixing plate 21, a first support base 23, a first guide rail 24 vertically mounted on the first support base 23, a slide plate 25 slidably mounted on the first guide rail 24, a bearing block 26 mounted on the slide plate 25 for lifting the outer shell 100, a limiting block 27 mounted at the lower end of the slide plate 25, and two ends respectively connected to the lower end surface of the limiting block 27 and the... The upper end face of the first fixing plate 21 abuts against the spring 28, several first pressing parts 29 and first positioning posts are arranged on the slide plate 25, and the slide plate 25 is also provided with a first through hole extending in the Y direction. The support seat is provided with a support post 20 that passes through the through hole and extends into the outer shell 100. The first quick clamp 22 shown is used to fix the first support seat 23 on the first fixing plate 21. When the outer shell 100 is not pressed down by the first pressing component 3, the support post 20 does not contact the inner wall of the outer shell 100.
[0025] In actual use, the No. 1 quick clamp 22 is used to fix the No. 1 support seat 23. After the outer shell 100 is positioned by the No. 1 positioning post and fixed by the No. 1 pressing component 29, the pin is manually pre-installed on the outer shell 100. During the pressing process of the No. 1 pressing component 3, the outer shell 100 is subjected to downward pressure, which drives the slide plate 25 to move down along the No. 1 guide rail 24 in sync. The spring 28 is compressed, so that the inner wall of the outer shell 100 abuts against the support post 20. After the No. 1 pressing component 3 continues to press down, the pin is assembled with the shaft hole of the outer shell 100.
[0026] In the above design, the structure of the first fixture 2 can reduce the impact on the outer shell 100 during the assembly of the pin by using the floating of the sliding plate 25, and at the same time, it can fix the outer shell 100 from the inside by using the support column 20, thereby improving the assembly efficiency and reducing the probability of damage to the outer shell 100 during the assembly process.
[0027] Specifically: such as Figure 3As shown, the second fixture 4 includes a second fixing plate 41 fixedly mounted on the upper end face of the frame 1, several second quick clamps 42 mounted on the second fixing plate 41, a second support seat 43, a support shaft 44 mounted on the second support seat 43 for supporting the outer shell 100, several second pressing parts 45 and second positioning posts mounted on the second support seat 43. The second fixing plate 41 and the second support seat 43 are provided with vertical holes for avoiding the top material assembly 6. The second quick clamps 42 are used to fix the support seat on the second fixing plate 41.
[0028] In actual use, the outer casing 100 is positioned on the second support base 43 using the second positioning post, and then the outer casing 100 is pressed tightly using the second pressing component 45. The bushing is then manually pre-installed on the outer casing 100. During the bushing pressing process, the outer casing 100 is supported from the inside by the support shaft 44. The top material assembly 6 supports the outer casing 100 from below through the vertical hole.
[0029] In the above design, the structural design and specific implementation of the No. 2 fixture 4 facilitates cooperation with the top material mechanism and the No. 2 pressing component 5 to press the bushing into the outer shell 100.
[0030] Specifically: such as Figure 2 , Figure 3 and Figure 4 As shown, the No. 1 pressing component 29 and the No. 2 pressing component 45 have the same structure. The No. 2 pressing component 45 includes a No. 2 cylinder 451 set on the No. 2 support seat 43, an L-shaped block 452 set on the No. 2 support seat 43, a pressing rod 453 hinged to the L-shaped block 452, and a No. 3 rod 454 whose two ends are respectively hinged to the output end of the No. 2 cylinder 451 and one end of the pressing rod 453. The hinge point between the L-shaped block 452 and the pressing rod 453 is located between the two ends of the pressing rod 453. The output end of the No. 2 cylinder 451 extends out and drives the No. 3 rod 454 and the pressing rod 453 to rotate.
[0031] When it is necessary to fix the outer casing 100, after the outer casing 100 is positioned by the second positioning pin, the output end of the second cylinder 451 extends, driving the third rod 454 to rotate. During the rotation of the third rod 454, the pressure rod 453 rotates, and the rotation of the pressure rod 453 presses one end of the pressure rod 453 against the outer casing 100. When it is necessary to release the outer casing 100, the second cylinder 451 resets, causing the third rod 454 to rotate and drive the pressure rod 453 to disengage from the outer casing 100.
[0032] In the above design, the structural design and specific implementation of the first pressing component 29 and the second pressing component 45 facilitate the fixing of the outer shell 100.
[0033] Specifically: such as Figure 1As shown, the No. 1 pressing assembly 3 includes a No. 1 support 31 mounted on the frame 1, a No. 1 lifting frame 32 mounted on the No. 1 support 31, a No. 1 electric cylinder 33 mounted on the No. 1 support 31 for driving the No. 1 lifting frame 32 to rise and fall, and a No. 1 pressing head 34 mounted on the lower end face of the No. 1 lifting frame 32.
[0034] In actual use, after the outer shell 100 in the first fixture 2 is fixed, the pin is pre-installed, and then the electric cylinder drives the first lifting frame 32 to move down, so that the first lifting frame 32 drives the first pressure head 34 to move down to achieve downward compression of the pin until the pin and the outer shell 100 are assembled. Then the first electric cylinder 33 drives the first lifting frame 32 to drive the first pressure head 34 to reset.
[0035] In the above design, the structural design and specific implementation of the first pressing component 3 facilitate the rapid pressing of the pin into the outer shell 100.
[0036] Specifically: such as Figure 5 As shown, the second pressing assembly 5 includes a second support 51 mounted on the frame 1, a second lifting frame 52 mounted on the second support 51, a second electric cylinder 53 mounted on the second support 51 for driving the second lifting frame 52 to rise and fall, a guide frame 54 mounted at the lower end of the second lifting frame 52, a second pressing head 55 slidably and vertically connected to the guide frame 54, and an elastic element 56 sleeved on the second pressing head 55. The second pressing head 55 is provided with a limiting protrusion 57, and the two ends of the elastic element 56 abut against the limiting protrusion 57 and the guide frame 54, respectively.
[0037] In actual use, after the outer shell 100 is fixed in the second fixture 4 with the bushing pre-installed, the second electric cylinder 53 drives the second lifting frame 52 to move down, so that the second lifting frame 52 drives the guide frame 54 and the second pressure head 55 to move down synchronously. When the second pressure head 55 contacts the bushing and continues to move down, the elastic element 56 is compressed. The downward speed of the second pressure head 55 is lower than the downward speed of the second lifting frame 52, so that the second pressure head 55 slowly squeezes the bushing until the bushing and the outer shell 100 are assembled.
[0038] In the above design, the structural design and specific implementation of the second pressing component 5 facilitate the use of the elastic element 56 to reduce the impact of the second pressing head 55 on the bushing when the bushing is pressed into the outer shell 100.
[0039] Specifically: such as Figure 1 and Figure 3 As shown, the top material assembly 6 includes a mounting bracket 61 disposed in the frame 1, a third cylinder 62 vertically disposed on the mounting bracket 61, and a top rod 63 disposed at the output end of the third cylinder 62. The top rod 63 passes through the upper end face of the frame 1 and the second fixture 4 and abuts against the outer shell 100.
[0040] In actual use, when the outer casing 100 is fixed on the second fixture 4 in preparation for bushing assembly, the third cylinder 62 drives the push rod 63 to rise, so that the push rod 63 supports the outer casing 100 from below.
[0041] In the above design, the structural design and specific implementation of the top material component 6 can effectively support the outer shell 100.
[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.
