Description

Technical Field

[0001] This utility model relates to the field of electronic throttle valve manufacturing, specifically to a valve plate mounting device for an electronic throttle valve. Background Technology

[0002] An electronic throttle valve consists of a housing, a valve hinge that rotates the valve plate and is assembled with the housing, and other components. During the production of an electronic throttle valve, the assembly precision of the valve plate and valve hinge directly affects the product's sealing and control performance. Traditional assembly processes rely heavily on manual adjustment of the valve plate position and detection of valve hinge runout (runout is an unintended displacement or loosening of mechanical components (such as shafts, pistons, guide rails, etc.) in the axial direction. This movement is usually due to small clearances allowed by design or non-ideal phenomena caused by assembly / wear, which may affect the accuracy, stability, and lifespan of the equipment), resulting in low efficiency and poor consistency. While existing automated equipment can improve efficiency, the detection and adjustment of valve hinge axial runout are still not precise enough, leading to poor fit between the valve plate and housing after installation, easily causing airtightness defects or movement jamming.

[0003] Therefore, it is necessary to provide a valve plate mounting device for an electronic throttle valve. Summary of the Invention

[0004] This utility model provides a valve plate mounting device for an electronic throttle body, which effectively solves the problem of low detection efficiency of valve shaft movement in the existing electronic throttle body production process.

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

[0006] The valve plate mounting device for an electronic throttle valve includes a frame, a fixture mounted on the frame, a door hinge movement detection mechanism mounted on the frame, a valve plate adjustment mechanism mounted on the frame for adjusting the valve plate in the fixture, and a screw locking mechanism mounted on the frame for locking the valve plate to the door hinge. The door hinge movement detection mechanism includes a left push-locking mechanism located at one end of the door hinge and a right push-sensing locking mechanism located at the other end of the door hinge.

[0021] 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.

[0022] like Figure 1 and Figure 6 As shown, the electronic throttle valve plate mounting device provided in the embodiment of this application includes a frame 1, a fixture 2 mounted on the frame 1, a door hinge movement detection mechanism mounted on the frame 1, a valve plate adjustment mechanism 3 mounted on the frame 1 for adjusting the valve plate 200 in the fixture 2, and a screw locking mechanism 4 mounted on the frame 1 for locking the valve plate 200 to the door hinge 100. The door hinge movement detection mechanism includes a left push locking mechanism 5 mounted on the frame 1 at one end of the door hinge 100 and a right push sensing locking mechanism 6 located at the other end of the door hinge 100.

[0023] It should be noted that the electronic throttle valve of this application is a semi-finished product, including a housing 300, a door hinge 100, and a valve plate 200. The door hinge 100 is pre-assembled with the housing 300, and for ease of understanding, it will be referred to as a semi-finished product from now on. The function of this application is to assemble the valve plate 200 with the door hinge 100. This application also includes a PLC control system, which controls the automatic operation of the door hinge movement detection mechanism, the fixture 2, the valve plate adjustment mechanism 3, and the screw locking mechanism 4.

[0024] In actual use, the semi-finished product is placed and fixed on fixture 2, then the valve plate 200 is placed on the door hinge 100. The valve plate adjustment mechanism 3 then adjusts the valve plate 200 to a horizontal position. Subsequently, the left push-locking mechanism 5 completes the play adjustment of the door hinge 100. The right push-sensing locking mechanism 6 senses the amount of movement of the door hinge 100, and then the screw-locking mechanism 4 locks the valve plate 200 onto the door hinge 100. The product is then removed from fixture 2.

[0025] The above design can detect whether the movement of the door hinge 100 is qualified, reduce and improve the accuracy of the door hinge 100 and the housing 300, thereby improving the installation accuracy of the valve plate 200.

[0026] Specifically: such as Figure 2 As shown, the left push-locking mechanism 5 includes a first linear guide rail 51 arranged along the X-axis on the frame 1, a first plate 52 slidably arranged on the linear guide rail, an electric cylinder 53 fixedly arranged on the frame 1 for driving the first plate 52 to move along the first linear guide rail 51, a fixed box 54 arranged on the first plate 52 and having a sliding hole, a first push rod 55 slidably connected to the fixed box 54 through the sliding hole, a first cylinder A56 fixedly arranged on the first plate 52 for driving the first push rod 55 to move, and a clamping mechanism for clamping the first push rod 55 arranged on the fixed box 54. Clamping assembly 57; The right push-sensing locking mechanism 6 includes a support 61 mounted on the frame 1, a second mounting box 62 mounted on the support 61, a second push rod 63 slidably mounted on the second mounting box 62 along the X-axis, a clamping member 64 mounted on the second mounting box 62 for clamping the second push rod 63, an eighth cylinder 67 mounted on the support 61 for driving the second push rod 63 to move, a sensing plate 65 fixedly mounted on the second push rod 63, and a displacement sensor 66 fixedly mounted on the support 61 for detecting the displacement of the sensing plate 65.

[0027] It should be noted that the driving force of electric cylinder 53 is greater than that of cylinder A56 (number one) and cylinder 67 (number eight). Cylinder 67 (number eight) is a single-acting cylinder with a compression spring inside, which can drive the output end to reset.

[0028] In actual use, clamping member 64 and clamping assembly 57 open, the output end of cylinder 8 67 extends to drive push rod 63 to push the right side of door hinge 100, and the output end of cylinder 1 A56 extends to drive push rod 55 to move to the right, so that door hinge 100 is centered. At this time, the sensing value of right-push-locking mechanism 6 is zero, and the air pressure of cylinder 8 67 is not locked, while cylinder 1 A56 is locked. Then, electric cylinder 53 drives plate 52 to move to the right, which drives cylinder 1 A56 to drive door hinge 100 to move to the right, so that push rod 63 and sensing plate 65 move to the right by a corresponding distance. At this time, displacement sensor 66 senses the position change of sensing plate 65, which is the axial clearance. Subsequently, electric cylinder 53 moves to the left to the preset displacement, causing cylinder A56 to move push rod 55 synchronously. The output of cylinder 67, driven by a compression spring, pushes push rod 63 to the left, causing the two ends of door hinge 100 to abut against push rods 55 and 63, thus adjusting the displacement of door hinge 100. Then, the locking mechanism locks push rod 63, and the locking assembly locks push rod 55. The screw-locking mechanism 4 screws onto valve plate 200 and door hinge 100.

[0029] In the above design, the structural design of the left push-locking mechanism 5 and the right push-sensing locking mechanism 6 facilitates the detection of the movement of the door hinge 100. At the same time, the door hinge 100 is fixed by the first push rod 55 and the second push rod 63 to ensure the stability of the door hinge 100 when locked with the valve plate 200, thereby improving the assembly accuracy.

[0030] Specifically: such as Figure 3 As shown, both sides of the first push rod 55 are provided with planes. The clamping assembly 57 includes two first pressure rods 572 symmetrically arranged on the first mounting box and corresponding one-to-one with the two planes, and two first cylinders B571 symmetrically arranged on the first mounting box for driving the two first pressure rods 572 to move along the Y-axis.

[0031] In actual use, when it is necessary to lock the first push rod 55, the two first cylinders B571 drive the two first pressure rods 572 to abut against the two planes respectively, so that the first push rod 55 is fixed.

[0032] In the above design, the structural design and specific implementation of the clamping assembly 57 and the first push rod 55 facilitate the prevention of the door hinge 100 from moving to the left during the locking process by fixing the first push rod 55.

[0033] Specifically: such as Figure 1As shown, the screw-locking mechanism 4 includes a screw feeder 41 mounted on the frame 1, a mounting base 42 mounted on the frame 1, a linear module 43 mounted on the mounting base 42 along the X-axis, a movable plate 44 fixedly mounted on the output end of the linear module 43, a No. 7 cylinder 45 mounted on the movable plate 44 along the Z-axis, a connecting frame mounted on the output end of the No. 7 cylinder 45, and a screw gun 46 mounted on the connecting frame. The head of the screw gun 46 corresponds vertically to the door hinge 100.

[0034] It should be noted that the screw gun 46 is automatically fed by the screw feeder 41, which is an existing structure and technology.

[0035] In actual use, screws are automatically supplied to screw gun 46 by screw feeder 41, and linear module 43 drives moving plate 44 to move along X-axis direction so that screw gun 46 is aligned with the hole to be locked on valve plate 200. Then, cylinder No. 7 drives screw gun 46 to move down to lock valve plate 200 to door hinge 100.

[0036] In the above design, the structural design and specific implementation of the screw locking mechanism 4 can effectively realize the automatic locking of the valve plate 200 and the door hinge 100.

[0037] Specifically: the clamping member 64 has the same structure as the clamping assembly 57, and the second push rod 63 has the same structure as the first push rod 55.

[0038] Specifically: such as Figure 4 and Figure 5 As shown, the fixture 2 includes a base 21 mounted on the frame 1 and having a vertical through hole, positioning pins 22 mounted on the base 21 for positioning the product, and several pressing components 23 mounted on the base 21. Each pressing component 23 includes a fixing block 231 mounted on the base 21, a pressing block 234 rotatably mounted on the fixing block 231, a third cylinder 232 mounted on the fixing block 231 for driving the pressing block 234 to rotate and press the product, and compression springs 233 whose two ends respectively abut against the pressing block 234 and the fixing block 231. The compression springs 233 abut against the lower end of the pressing block 234, and the output end of the third cylinder 232 is located at the upper end of the compression spring 233. The valve plate adjustment mechanism 3 adjusts the valve plate 200 through the vertical through hole. It should be noted that the outer shell 300 of the semi-finished product has positioning holes.

[0039] In actual use, the third cylinder 232 disengages from the pressure block 234, causing the compression spring 233 to apply pressure to the lower end of the pressure block 234. Since the hinge point between the pressure block 234 and the fixing block 231 is located in the middle of the pressure block 234, the pressure block 234 opens under the elastic force of the compression spring 233. The semi-finished product is then positioned on the housing through the positioning pin 22 and positioning hole. Subsequently, the third cylinder 232 drives the upper end of the pressure block 234, causing the pressure block 234 to rotate and press against the housing. When it is necessary to remove the material, the third cylinder 232 disengages from the pressure block 234, causing the compression spring 233 to open the pressure block 234.

[0040] In the above design, the structural design and specific implementation of the fixture 2 facilitate the automatic clamping and automatic release of the product.

[0041] Specifically: such as Figure 4 As shown, the valve plate adjustment mechanism 3 includes a fixed frame located below the frame 1, a No. 5 cylinder 31 and a No. 6 cylinder 32 arranged along the Y-axis on the fixed frame, a No. 5 push rod 33 and a No. 6 push rod 34 slidably connected to the fixed frame, the output end of the No. 5 cylinder 31 being connected to the lower end of the No. 5 push rod 33, and the output end of the No. 6 push rod 34 being connected to the lower end of the No. 6 push rod 34, the No. 6 push rod 34 and the No. 5 push rod 33 being located on both sides of the door hinge 100, and the upper ends of the No. 6 push rod 34 and the No. 5 push rod 33 being raised to abut against the valve plate 200 on both sides of the door hinge 100.

[0042] In actual use, after the valve plate 200 is placed on the door hinge 100, the output ends of cylinders 6 and 5 drive the push rods 34 and 33 to rise respectively, making contact with the areas of the valve plate 200 on both sides of the door hinge 100, so that the areas on both sides of the door hinge 100 are horizontal, that is, the entire valve plate 200 is horizontal. Then the screws are tightened.

[0043] In the above design, the structural design and specific implementation of the valve plate adjustment mechanism 3 facilitate the adjustment of the valve plate 200 to a horizontal position, thereby improving the assembly accuracy of the valve plate 200 and the door hinge 100.

[0044] 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.
