[0002] The throttle is a valve component in the automobile engine that controls the air intake. It can regulate the air intake of the engine. Therefore, after the throttle is manufactured, its air flow needs to be tested.

[0003] During testing, the throttle valve needs to be fixed with a tool, and then the desorption pipe hole and the injector mounting hole on the throttle valve housing are blocked with a plug to ensure that the gas only flows through the throttle valve's ventilation pipe.

[0004] The existing tooling generally places the throttle on a base, and then uses a cylinder to vertically press down the top of the throttle to clamp and fix the throttle (avoiding the throttle's ventilation pipe), and then uses other cylinders to push the blockage to seal the desorption tube hole and the injector respectively. However, this work uses a large number of cylinders, resulting in a complex structure and high cost. Utility Model Content

[0005] The main purpose of the utility model is to provide a throttle air flow detection tooling, wherein the second sealing component can seal the injector mounting hole of the throttle along the inclination angle thereof, thereby causing the throttle to be subjected to an oblique force, and this oblique force can press the throttle down and fix it in the positioning hole, thereby eliminating the need for an additional throttle pressing component, simplifying the throttle working structure, and reducing manufacturing costs.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1-3 As shown, a throttle air flow detection tool includes a base 1, a positioning hole 2 matching the throttle is opened on the top of the base 1, a first plugging component 4 for plugging the throttle desorption tube hole is fixed on the top of one side of the base 1, and a second plugging component 3 is obliquely arranged on the other side of the base 1, and the second plugging component 3 is used for obliquely plugging the injector mounting hole of the throttle.

[0027] In this embodiment, if Figure 1 As shown, insert the throttle valve vent pipe into the positioning hole 2 and ensure that the throttle valve desorption pipe hole and the injector installation hole are aligned with the first plugging component 4 and the second plugging component 3 respectively;

[0028] The second plugging assembly 3 includes a first linear drive device 301 obliquely connected to the base 1, a connecting plate 302 is fixed to the driving end of the first linear drive device 301, a rod body 303 is arranged on the connecting plate 302, and a first plug 304 matching the throttle injector mounting hole is fixed to the bottom end of the rod body 303;

[0029] When blocking the fuel injector mounting hole of the throttle, since the fuel injector mounting hole is at a certain tilt angle relative to the base 1, the first linear drive device 301 drives the first plug 304 to move along the corresponding tilt angle, so that the first plug 304 blocks the fuel injector mounting hole. At this time, the throttle is subjected to an oblique force, and this oblique force can press the throttle down and fix it in the positioning hole 2, so there is no need to add an additional pressing component for the throttle;

[0030] Furthermore, since a rubber ring 5 is disposed at the bottom of the positioning hole 2 , under the action of the oblique force, the air vent at the bottom of the throttle valve will be in close contact with the rubber ring 5 .

[0031] Among them, Figure 1 As shown, the rod body 303 is threadedly connected to the connecting plate 302, so the length of the rod body 303 extending downward relative to the connecting plate 302 is adjustable, thereby changing the degree of deformation of the first plug 304 when blocking the injector mounting hole, ensuring that the first plug 304 can completely block the injector mounting hole.

[0032] Among them, Figure 1 As shown, the first blocking component 4 includes a mounting plate 401 connected to the base 1, the mounting plate 401 is L-shaped, and a second linear drive device 403 is horizontally installed on the vertical plate of the mounting plate 401, the driving end of the second linear drive device 403 points to the base 1 and is fixed with a second plug 402 matching the throttle desorption tube hole, when the second linear drive device 403 drives the second plug 402 to move horizontally, the second plug 402 can block the throttle desorption tube hole, and because the first plug 304 blocks the injector mounting hole, the gas can only enter and discharge from the throttle ventilation pipe, thereby facilitating the detection of the throttle air flow.

[0033] The first plug 304 and the second plug 402 are both made of rubber.

[0034] The first linear drive device 301 and the second linear drive device 403 are pneumatic cylinders or electric cylinders.

[0035] Among them, Figure 2 As shown, a groove 8 is provided at the bottom of the base 1, and a ventilation component 7 is arranged in the groove 8. The ventilation component 7 includes a ventilation hole 701 provided at the top of the groove 8, and the ventilation hole 701 is connected to the bottom of the positioning hole 2. The ventilation hole 701 is threadedly connected with a ventilation pipe 702. Therefore, the gas in the positioning hole 2 can be discharged through the ventilation pipe 702, and a trachea quick-plug connector 703 is fixed on the ventilation pipe 702 located in the groove 8. Therefore, after connecting the pipeline of the detection equipment to the trachea quick-plug connector 703, the gas can pass through the throttle by using negative pressure, and then the volume of the gas passing through the throttle per unit time is measured to calculate the air flow rate of the throttle. This is the prior art and will not be elaborated here.

[0036] Among them, Figure 3 As shown, a limiting plate 9 is arranged on the periphery of the vent pipe 702, and a sealing ring 10 is connected to the end face where the limiting plate 9 contacts the top of the groove 8, and the vent pipe 702 is threadedly connected to the vent hole 701. When the limiting plate 9 contacts the top of the groove 8, it indicates that the vent pipe 702 is connected in place, and the sealing ring 10 can improve the sealing between the vent pipes 702 and the vent pipes 702.

[0037] Working principle, first, insert the throttle valve's air pipe into the positioning hole 2 and ensure that the throttle valve's air valve desorption tube hole and the injector mounting hole are aligned with the first blocking component 4 and the second blocking component 3 respectively, then, drive the first plug 304 to move along through the first linear drive device 301, so that the first plug 304 blocks the injector mounting hole, at this time, the throttle valve is subjected to an oblique force, under the action of this oblique force, the throttle valve will be pressed down and fixed into the positioning hole 2, so that there is no need to add an additional pressing component for the throttle valve, next, use the second linear drive device 403 to drive the second plug 402 to move horizontally, so that the second plug 402 can block the throttle valve's desorption tube hole, and because the first plug 304 blocks the injector mounting hole, the gas can only enter and discharge from the throttle valve's air pipe, which facilitates the detection of the throttle valve's air flow.

[0038] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
