Description

TECHNICAL FIELD

[0001] The utility model relates to the field of automobile throttle, especially a bowl plug press fitting device for throttle. BACKGROUND

[0002] In the production process of the throttle, a bowl plug needs to be press fitted into the end part of the throttle shaft on the throttle body to seal one side of the throttle shaft.

[0003] The bowl plug used is shown in the drawing, which is internally provided with a bowl plug groove, and the outer contour of the lower part of the bowl plug is slightly arc-shaped. Figure 1 When the operator manually butts the bowl plug against the corresponding mounting hole on the throttle body (i.e. directly places the lower part of the bowl plug against the hole of the mounting hole), the bowl plug may not be accurately placed on the corresponding press fitting position of the mounting hole due to manual operation. Meanwhile, after the bowl plug is butted against the mounting hole, the pressing block is directly started to press down, which causes the lower part of the bowl plug to easily deviate laterally in the process of the pressing block applying force downward from top to bottom to press fit the bowl plug, thereby causing the press fitting to be out of position or to fail. SUMMARY

[0004] The utility model aims at providing a bowl plug press fitting device for throttle, which solves the technical problem that the bowl plug easily deviates laterally in the press fitting process. The utility model has simple structure and lower cost.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] A bowl plug press fitting device for throttle, comprising a bottom plate, the upper end of the bottom plate is provided with a positioning mechanism, the upper part of the positioning mechanism is provided with a pressing block mechanism;

[0007] The positioning mechanism comprises a side stand, a throttle body support positioning assembly, a bowl plug positioning assembly and a throttle body side pressing assembly;

[0008] The throttle body support positioning assembly comprises two positioning support blocks which are connected to the front side wall of the side stand and are distributed left and right, an avoiding groove is arranged between the two positioning support blocks, the avoiding groove is through from below and is open at the front side;

[0009] The bowl plug positioning assembly comprises a guide plate connected to the front side wall of the side stand and a top pressing rod slidingly connected with the guide plate; the lower end of the top pressing rod is located directly above the avoiding groove, and the lower end side wall of the top pressing rod is radially provided with an elastic component;

[0010] The throttle body side pressing assembly comprises a side pressing block and a driving component one which drives the side pressing block to push towards the avoiding groove;

[0011] The pressing mechanism comprises a pressing block above the top pressing rod and a driving component two for moving the pressing block up and down.

[0012] Further, it also comprises a sliding plate and a driving component three for moving the sliding plate;

[0013] The sliding plate is slidably connected with the bottom plate; the side vertical plate is fixedly connected with the upper end of the sliding plate, and the driving component two is fixedly connected with the upper end of the sliding plate.

[0014] Further, it also comprises a support plate and four support columns; the driving component two is fixedly connected with the support plate, and the support plate is fixed on the top of the positioning mechanism through the four support columns.

[0015] Further, the outer wall of the top pressing rod is provided with a groove, and the guide plate is provided with a wave bead screw matched with the groove.

[0016] Further, the elastic component is a rubber ring.

[0017] Further, the driving component one is a side pressing cylinder; and the driving component two is a servo motor.

[0018] Compared with the prior art, the bowl-shaped plug pressing device for the throttle valve has the following beneficial effects:

[0019] In the utility model, the elastic component is arranged on the lower end side wall of the top pressing rod in the radial direction; and the lower end of the top pressing rod is located directly above the avoiding groove. During operation, the bowl-shaped plug can be sleeved on the periphery of the elastic component. Since the elastic component is distributed in the radial direction and has a certain expansion tension, the bowl-shaped plug can be expanded between the outer wall of the top pressing rod and the bowl-shaped plug, so that the relative fastening state of the bowl-shaped plug and the top pressing rod is realized, and the transverse position of the bowl-shaped plug can be quickly defined. During operation, the mounting hole is located directly below the lower end of the top pressing rod. During the pressing process of the top pressing rod, the bowl-shaped plug cannot fall off because it is always sleeved on the periphery of the lower end of the top pressing rod, and the bowl-shaped plug cannot easily displace in the transverse direction. Therefore, the top pressing rod can press into the mounting hole below by aligning the bowl-shaped plug with the mounting hole below, so that the bowl-shaped plug is accurately and quickly pressed into the mounting hole below.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0030] As shown in Figures 1-7 , the utility model provides a bowl-shaped plug pressing device for throttle, including bottom plate 10, the upper end of bottom plate 10 is equipped with positioning mechanism, the upper portion of positioning mechanism is equipped with pressing block mechanism.

[0031] In the embodiment, positioning mechanism as shown in Figure 3 、 4 .

[0032] As shown in Figure 3 、 4 , in the embodiment, the positioning mechanism includes side vertical plate 22, throttle body support positioning assembly, bowl-shaped plug positioning assembly and throttle body side pressing assembly.

[0033] In this embodiment, the throttle body supporting and positioning assembly comprises two positioning supporting blocks 24 connected to the front side wall of the side stand 22 and distributed left and right, and an avoiding slot 241 is arranged between the two positioning supporting blocks 24, which penetrates downward and opens at the front. The avoiding slot 241 is used for avoiding the throttle valve plate and the throttle shaft which have been pre-assembled with the throttle body. In operation, the throttle valve plate is rotated and then inserted from front to back to align with the avoiding slot 241, so that half of the throttle valve plate and the throttle shaft are arranged in the avoiding slot 241, and at the same time, the throttle body 60 is pressed against the front wall of the limiting baffle 23, at this time, the throttle body 60 is supported by the upper ends of the two positioning supporting blocks 24. As shown in Figure 4 , the limiting baffle 23 is fixedly connected to the front side wall of the side stand 22, and the throttle body 60 is sleeved on the outer circle of the two positioning supporting blocks 24.

[0034] In this embodiment, the bowl-shaped plug positioning assembly comprises a guide plate 29 connected to the front side wall of the side stand 22 and a pressing rod 28 in sliding connection with the guide plate 29; the lower end of the pressing rod 28 is located directly above the avoiding slot 241, and the lower end side wall of the pressing rod 28 is provided with an elastic component in the radial direction. As shown in Figure 5 , in this embodiment, the elastic component is an O-shaped rubber ring 40 arranged on the lower end side wall of the pressing rod 28 in the radial direction. Specifically, the rubber ring 40 is located in the annular clamping groove 282 formed in the lower end side wall of the pressing rod 28.

[0035] As shown in Figure 5 , it is a structural schematic view of the pressing rod 28 in this embodiment. The rubber ring 40 is sleeved in the annular clamping groove 282, and the outer circle of the rubber ring 40 protrudes transversely from the clamping groove lower edge 283 of the annular clamping groove 282, as shown in Figure 5 , 7 , when the bowl-shaped plug 50 is sleeved on the lower end of the pressing rod 28 from bottom to top, the rubber ring 40 can be in close contact with the inner wall of the bowl-shaped plug groove 51; at the same time, when the bowl-shaped plug 50 is pressed into the mounting hole 61 and the pressing rod 28 is reset and moves upward, the pressing rod 28 is separated from the bowl-shaped plug 50, and the rubber ring 40 is blocked by the clamping groove lower edge 283 and cannot be easily separated from the pressing rod 28. Of course, we can also take advantage of the elastic characteristics of the rubber ring 40 itself, select a rubber ring 40 with a slightly smaller inner diameter, and then tighten it in the annular clamping groove 282 to enhance the connection strength between the rubber ring 40 and the pressing rod 28.

[0036] Specifically, in operation, we will sleeve the bowl-shaped plug 50 on the outer circle of the rubber ring 40, as shown in Figure 6As shown, due to the elasticity of the rubber ring 40, when the cup-shaped plug 50 is fitted onto the outer ring of the rubber ring 40, the rubber ring 40 expands tightly between the cup-shaped plug 50 and the outer wall of the push rod 28, thus temporarily connecting the cup-shaped plug 50 to the lower end of the push rod 28 without it falling off. Simultaneously, since the mounting hole 61 on the throttle body 60 is located directly below the lower end of the push rod 28 after the throttle body 60 presses backward against the front wall of the limiting baffle 23, the cup-shaped plug 50 fitted onto the outer ring of the rubber ring 40 is located directly above the mounting hole 61.

[0037] When the top pressure rod 28 is located directly below the pressing block 30, the pressing block 30 presses the top pressure rod 28 downward, which can accurately press the cup-shaped plug 50 into the mounting hole 61. During the operation, since the cup-shaped plug 50 is sleeved on the outer ring of the rubber ring 40, the lateral position of the cup-shaped plug 50 is relatively stable during the downward movement of the top pressure rod 28 and the downward pressure, and there will be no excessive lateral displacement.

[0038] Preferably, such as Figure 5 As shown, a groove 281 is also provided on the side wall of the top pressure rod 28. The groove 281 is annular, as shown in the figure. Figure 4 As shown, a ball screw 284 matching the groove 281 is provided on the side wall of the guide plate 29. A guide sleeve is also provided between the guide plate 29 and the top pressure rod 28. The ball screw 284 can pass through the guide plate 29 and the guide sleeve and be engaged in the groove 281.

[0039] When the ball screw 284 is engaged in the groove 281 (elastic engagement), the longitudinal force applied to the top pressure rod 28 stops. At this time, the position of the top pressure rod 28 is temporarily locked, and the top pressure rod 28 will not fall downwards. The cup-shaped plug 50 is located at a preset height directly above the mounting hole 61. When the top pressure rod 28 moves downwards under the pressure of the pressing block 30, the ball screw 284 exits the groove 281, and the top pressure rod 28 can move downwards.

[0040] like Figure 3 As shown, in this embodiment, the pressing mechanism includes a pressing block 30 located above the top pressing rod 28 and a second driving component that drives the pressing block 30 to move up and down. In this embodiment, the second driving component is a servo motor 33, which is fixedly connected to the support plate 31, and the pressing block 30 is connected to the moving end of the servo motor 33.

[0041] Meanwhile, the support plate 31 is fixed above the positioning mechanism by four support columns 32, such as Figure 2 As shown.

[0042] In this embodiment, the throttle body side-pressure assembly includes a side-pressure block 25 and a drive component 1 that pushes the side-pressure block 25 towards the clearance groove 241. This drive component 1 is a side-pressure cylinder 26. The function of the throttle body side-pressure assembly is to push the throttle body 60 backward, causing the throttle body 60 to press tightly against the front wall of the limiting baffle 23, thereby ensuring that the throttle body 60 is locked between the side-pressure block 25 and the limiting baffle 23, and will not easily shift during operation. Figure 4 As shown, driven by the side pressure cylinder 26, the side pressure block 25 presses back against one end of the throttle body 60, pushing it toward the front wall of the limit baffle 23.

[0043] like Figure 4 As shown, in this embodiment, both the side pressure cylinder 26 and the side upright plate 22 are fixed to the upper end of the sliding plate 20, while the lower end of the sliding plate 20 is slidably connected to the slide rail 27 via a slider. The slide rail 27 is fixed to the upper end of the base plate 10 via a fixing plate 11, thereby indirectly realizing the sliding connection between the sliding plate 20 and the base plate 10. In this embodiment, the sliding plate 20 is driven by the driving component three, namely the push cylinder 21. Under the drive of the push cylinder 21, the sliding plate 20 can move along the slide rail 27 in the front-back direction.

[0044] During operation, the operator is positioned in front of the base plate 10. When the sliding plate 20 moves forward under the drive of the push cylinder 21, it can simultaneously move the throttle body support and positioning assembly, the cup-shaped plug positioning assembly, and the throttle body side pressure assembly forward, i.e., towards the operator. After moving into position, the operator can easily place the cup-shaped plug 50 on the outer ring of the rubber ring 40 at the lower end of the top pressure rod 28, and place the throttle body 60 on the outer ring of the positioning support block 24. Then, the side pressure cylinder 26 is activated, and the side pressure block 25 presses the throttle body 60 towards the rear limit baffle 23.

[0045] Then, the push cylinder 21 is activated, which drives the sliding plate 20 to move backward until the top pressure rod 28 is directly below the pressing block 30. After the top pressure rod 28 is directly below the pressing block 30, the servo motor 33 is activated, and the pressing block 30 presses down, pressing the top pressure rod 28 downward and pressing the cup-shaped plug 50 into the mounting hole 61 below.

[0046] After the cup-shaped plug 50 is fitted onto the outer ring of the rubber ring 40 at the lower end of the top pressure rod 28, before the push cylinder 21 drives the sliding plate 20 to move backward, we ensure that the ball screw 284 is engaged in the groove 281 (elastic engagement). This temporarily locks the relative position between the top pressure rod 28 and the guide plate 29, preventing the top pressure rod 28 from falling down. At the same time, the cup-shaped plug 50 is located at a preset height directly above the mounting hole 61.

[0047] After the bowl-shaped plug 50 is pressed into the mounting hole 61, the pressing block 30 is reset to move upward, and the sliding plate 20 is driven by the push cylinder 21 to move forward again; after the sliding plate 20 stops, the operator can manually pull the pressing rod 28 upward, and the rubber ring 40 is separated from the bowl-shaped plug groove 51; when the wave bead screw 284 enters the groove 281, the pressing rod 28 is loosened, and the upward force is no longer applied to the pressing rod 28. At the same time, after the side pressing cylinder 26 drives the side pressing block 25 to move back to the direction away from the throttle body 60, the operator removes the pressing completed throttle body 60 from the pressing device.

[0048] The pressing device in the embodiment can quickly and accurately press the bowl-shaped plug 50 into the mounting hole 61 on the throttle body 60, and the operation is simple and fast.
