[0026] The technical solutions in the embodiments of the utility model will be clearly 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 scope of protection of the utility model.

[0027] As shown in Figures 1-7 , the utility model provides a sealing ring press fitting device for throttle dust cover.

[0028] The sealing ring press fitting device for throttle dust cover comprises a base plate 1, and the upper end of the base plate 1 is provided with a side stand 2 and a dust cover limiting block 3.

[0029] As shown in Figure 1 , the upper end of the dust cover limiting block 3 is further provided with a dust cover limiting groove 31 with an upward opening; and the side stand 2 is connected with a press fitting mechanism. Figure 2 、 3 As shown.

[0030] In the embodiment, the press fitting mechanism is connected to the side wall of the side stand 2, and comprises a mounting block one 43, a driving component one 41 for driving the mounting block one 43 to move up and down, a sealing ring pressing block 48 in sliding connection with the side wall of the mounting block one 43, a driving component two 44 for driving the sealing ring pressing block 48 to move up and down, a connecting block 45 fixedly connected with the mounting block one 43, and a profiling pressing block 46 connected with the connecting block 45.

[0031] Specifically, as shown in Figure 2 , the rear end of the mounting block one 43 is provided with a sliding block one, which is in sliding connection with a slideway one 42 on the side wall of the side stand 2, and the slideway one 42 extends longitudinally, thereby realizing the up and down sliding connection between the mounting block one 43 and the side stand 2.

[0032] Similarly, the rear end of the sealing ring pressing block 48 is connected with a mounting block two 49. The rear end of the mounting block two 49 is provided with a sliding block two which is in sliding connection with a sliding rail two 47 on the front side wall of the mounting block one 43. The sliding rail two 47 extends longitudinally, the sealing ring pressing block 48 is fixedly connected with the mounting block two 49, the sliding block two is fixedly connected with the mounting block two 49, and the sliding block two slides up and down along the sliding rail two 47, thereby indirectly realizing the up and down sliding connection of the sealing ring pressing block 48 and the mounting block one 43.

[0033] Specifically, in the embodiment, the profiling pressing block 46 realizes the fixed connection with the mounting block one 43 through the connecting block 45, the driving component two 44 is fixedly connected with the connecting block 45, and the moving end of the driving component two 44 is connected with the upper end of the mounting block two 49. When the mounting block one 43 is driven by the driving component one 41 to move up and down, the connecting block 45, the profiling pressing block 46, the mounting block two 49 and the sealing ring pressing block 48 will be simultaneously driven to move up and down synchronously.

[0034] The driving component two 44 can separately drive the sealing ring pressing block 48 to move up and down. Specifically, when the mounting block one 43 is in a stationary state, the driving component two 44 drives the mounting block two 49 to move downward, thereby driving the sealing ring pressing block 48 to move downward. The sealing ring pressing block 48 which is sleeved on the outer circle of the profiling pressing block 46 can move downward relative to the profiling pressing block 46, so as to push downward the sealing ring 7 (as shown in Figure 4 ) which is sleeved on the outer wall of the profiling pressing block 46 and located below the sealing ring pressing block 48, so that the sealing ring 7 which is originally sleeved on the outer wall of the profiling pressing block 46 is separated downward from the profiling pressing block 46.

[0035] In the embodiment, the driving component one 41 and the driving component two 44 can be air cylinders.

[0036] As shown in Figure 1 , 2 , the profiling pressing block 46 and the sealing ring pressing block 48 are both located above the dust cover limiting groove 31. Specifically, the structure diagram of the sealing ring pressing block 48 is as shown in Figure 6 , an upper and lower through pressing block through groove 481 for the profiling pressing block 46 to pass through is arranged in the sealing ring pressing block 48. That is, when the profiling pressing block 46 is placed in the pressing block through groove 481, the sealing ring pressing block 48 is sleeved on the outer circle of the profiling pressing block 46. At this time, the gap between the outer wall of the profiling pressing block 46 and the sealing ring pressing block 48 is small, but they can move relative to each other, as shown in Figure 4 . At this time, we can sleeve the sealing ring 7 on the outer wall of the profiling pressing block 46, and make the sealing ring 7 located below the sealing ring pressing block 48, and the lower end of the sealing ring 7 is higher than the lower end of the profiling pressing block 46, as shown in Figure 4 . In Figure 4In this state, the sealing ring 7 is located directly below the sealing ring pressing block 48. When the sealing ring pressing block 48 is pressed down, the lower end face of the sealing ring pressing block 48 can press against the upper end face of the sealing ring 7.

[0037] Preferably, in this embodiment, a limiting post 51 and an elastic element 52 are provided below the mounting block 43; a limiting post 53 and an elastic element 54 are provided below the mounting block 49. The heights of the limiting post 51 and the limiting post 53 are fixed, which can be used to limit the downward movement height of the mounting block 43 and the mounting block 49 respectively, thereby avoiding excessive pressure on the dust cover 6 by the contour pressing block 46 and the sealing ring pressing block 48.

[0038] In this embodiment, after being fitted onto the outer ring of the contouring block 46, the shape of the sealing ring 7 is locked. Simultaneously, the contouring block 46 moves the sealing ring 7 downwards until it presses against the upper end of the inner baffle 62 of the slot. Furthermore, a clearance groove 461 is provided at the lower end of the contouring block 46. When the lower end of the contouring block 46 presses against the upper end of the inner baffle 62 of the slot, the clearance groove 461 can accommodate other components in the dust cover assembly that protrude from the upper surface of the inner baffle 62 of the slot. For example, the upper surface of some insert pieces may be higher than the upper surface of the inner baffle 62 of the slot.

[0039] At the same time, such as Figures 1-3 As shown, the upper end of elastic element 1 52 is higher than the upper end of limiting post 1 51, and the upper end of elastic element 2 54 is higher than the upper end of limiting post 2 53. Elastic element 1 52 and elastic element 2 54 can be used to buffer the mounting block 1 43 and mounting block 2 49 respectively during the downward movement process.

[0040] The usage of the sealing ring press-fitting device for the throttle body dust cover in this embodiment is briefly as follows:

[0041] First, as Figure 7 The dust cover assembly shown (i.e., the module consisting of the dust cover, ribbon cable, and PCB) is placed into the dust cover limiting groove 31, as shown. Figure 2 As shown in the image.

[0042] Then, the sealing ring 7 is fitted onto the outer wall of the conforming pressure block 46, with the sealing ring 7 positioned below the lower pressure block 48, and the lower end of the sealing ring 7 higher than the lower end of the conforming pressure block 46, as shown in the following figure. Figure 4 The state shown.

[0043] Next, drive component 41 is activated, and the contouring block 46 and the sealing ring lower block 48 move down synchronously until the lower end of the contouring block 46 presses against the upper end of the inner side baffle 62 of the slot; at this time, the lower end of the sealing ring 7 is positioned above the sealing ring slot 61.

[0044] like Figure 7As shown, the dust cover 6 is provided with a ring of clamping groove inner baffle 62, the outer side of the clamping groove inner baffle 62 is a sealing ring clamping groove 61.

[0045] Fourthly, the driving part two 44 is started to drive the mounting block two 49 to move downwards, and in turn drives the sealing ring lower pressing block 48 to move downwards, pushes the sealing ring 7 which is sleeved on the outer wall of the profiling pressing block 46 and located below the sealing ring lower pressing block 48 downwards, so that the sealing ring 7 which is originally sleeved on the outer wall of the profiling pressing block 46 is separated from the profiling pressing block 46 downwards and is pressed into the sealing ring clamping groove 61 below.

[0046] Through the sealing ring pressing device in the embodiment, the sealing ring can be quickly and accurately pressed into the dust cover.
