Abstract
The utility model discloses negative-pressure exhaust gas recycle (EGR) valve leakage detection craft equipment, which comprises a base provided with more than two mounting holes and is characterized in that an L-shaped support is connected with the base fixedly, a longitudinal cylinder and a transverse cylinder are arranged on the L-shaped support, a pressure head is arranged on a piston rod of the longitudinal cylinder, a sealing head is arranged on a piston rod of the transverse cylinder, a blind hole used for positioning and a baffle are arranged on a position of the base below the longitudinal cylinder, and a detection hole which is in communication with the blind hole is arranged on a side wall of the base. The negative-pressure EGR valve leakage detection craft equipment can accomplish two detection processes, so that the detection efficiency is improved, the deviation is small, and the labor cost is saved.
Description
Technical field
The utility model relates to a kind of frock that detects the valve seat and the orienting sleeve leakage parameters of suction type EGR valve.
Background technology
The EGR technology, promptly EGR Technology (Exhaust Gas Recycle) is the emission-control equipment that is provided with to harmful gas (NOx).It gets into combusted cylinder after a part of exhaust cycle is got into draft tube and fresh air mixes once more, and to increase the thermal capacity of combination gas, the maximum temperature when reducing burning suppresses the generation of NOx.In said process; Suction type EGR valve is as the executive component of a key; Brought into play enormous function, the EGR valve is adjusted the open degree of valve according to the negative pressure signal of engine real work load conversion in good time and accurately; Thereby adjustment gets into the exhausted air quantity of engine, plays the purpose of adjustment engine coda discharging then.
Suction type EGR valve product in process of production owing to receive parts quality, influences such as assembly technology; The existence of substandard product is arranged all the time; Showing as of substandard product: the curved line relation of input signal and output pressure is not linear, causes the aperture variation of vacuum tightness and EGR valve irregular, if this type of substandard product is used on automobile; Will cause being short of power of automobile, discharge the appearance of problems such as exceeding standard.
Flow out for fear of substandard product, suction type EGR valve production firm all can be detected the product of producing one by one, and in testing process; Because the requirement of properties of product also will guarantee the requirement of product detection of negative pressure when guaranteeing not damage product appearance, promptly the leakage parameters to valve seat and orienting sleeve detects; Existing detection frock generally is divided into two, and detection needs two procedures to accomplish, and such shortcoming is: efficient is too low; Error is big, and human cost is high.
The utility model content
The purpose of the utility model is the above-mentioned deficiency to prior art, and a kind of suction type EGR valve Leak Detection frock is provided, and it can be accomplished twice and detect operation, thereby improves detection efficiency, and error is less, can practice thrift human cost.
For achieving the above object, the suction type EGR valve Leak Detection frock of the utility model comprises the base that is provided with two above mounting holes; It is characterized in that on base, being fixedly connected with L bracket; One vertical cylinder and lateral cylinder is installed on L bracket, on the piston rod of vertical cylinder, is provided with pressure head, on the piston rod of lateral cylinder, be provided with seal head; On the base below vertical cylinder, also be provided with the blind hole and the baffle plate of location, on the sidewall of base, be provided with the detection hole that communicates with blind hole.
During use, connect leakage instrument from detecting the hole, leakage instrument connects data output device; The product that assembles is put into blind hole and baffle plate, drive vertical cylinder action and make pressure head descending, product is pressed on the base; Begin to detect seat leakage this moment, after this step action is accomplished, drive the lateral cylinder action seal head is stretched out; Side flange face seal with product; Make product cavity be in vacuum state, at this moment the testing product orienting sleeve leaks, after detection is accomplished; The action of two cylinders makes seal head and pressure head reply previous original state, and the testing staff can take out the outward appearance that does not injure product with product very easily; The utility model can be accomplished twice and detect operation, thereby improves detection efficiency, can practice thrift human cost;
As the further improvement of the utility model, on the base end face around the blind hole, be provided with seal groove, be provided with O-ring seal in the seal groove; O-ring seal can improve the sealing of product, thereby reduces measuring error;
In sum, the utility model can be accomplished twice and detect operation, thereby improves detection efficiency, and error is less, can practice thrift human cost.
Description of drawings
Fig. 1 is the front view of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed explanation.
By shown in Figure 1; This suction type EGR valve Leak Detection frock, comprise the base 1 that is provided with four mounting holes 5, with the L bracket 2 that base 1 connects firmly through bolt, a vertical cylinder 3 and a lateral cylinder 4 is installed on L bracket 2; On the piston rod of vertical cylinder 3, be provided with pressure head 6; On the piston rod of lateral cylinder 4, be provided with seal head 7, on the base below vertical cylinder 3, also be provided with the blind hole 8 and the baffle plate 9 of location, on the base end face around the blind hole 8, be provided with seal groove; Be provided with O-ring seal 10 in the seal groove, on the sidewall of base 1, also be provided with the detection hole 11 that communicates with blind hole 8.
During use, through mounting hole 5 base 1 is loaded on the worktable, connects leakage instrument from detecting hole 11, leakage instrument connects data output device; The product that assembles is put into blind hole 8 and baffle plate 9, drive vertical cylinder 3 actions and make pressure head 6 descending, product is pressed on the base 1; Begin to detect seat leakage this moment, after this step action is accomplished, drive lateral cylinder 4 actions seal head 7 is stretched out; Side flange face seal with product; Make product cavity be in vacuum state, at this moment the testing product orienting sleeve leaks, after detection is accomplished; 4,3 actions of two cylinders make seal head 7 and pressure head 6 reply previous original state, and the testing staff can take out the outward appearance that does not injure product with product very easily; The utility model can be accomplished twice and detect operation, thereby improves detection efficiency, can practice thrift human cost; O-ring seal 10 can improve the sealing of product, thereby reduces measuring error.
