Technical field

The utility model relates to a kind of pick-up unit, a kind of specifically actuator pick-up unit.

Background technology

Speed regulating actuator is a vitals of engine; The power output of speed regulating actuator and delivery stroke have material impact to the control of engine speed; If the power output of speed regulating actuator and delivery stroke be not in claimed range; Then can influence client's normal use, reduce product quality, even cause unacceptable product to come into the market.And so far, also do not have special pick-up unit that the power output and the delivery stroke of speed regulating actuator are detected simultaneously.

Summary of the invention

The purpose of the utility model is for solving the problems of the technologies described above, provide a kind of simple in structure, easy and simple to handle, the actuator pick-up unit that can be simultaneously the power output and the delivery stroke of the actuator under the duty be detected.

Technical scheme comprises base; Said base is provided with fixing part that is used for fixing actuator and the test section that is used to detect displacement and push-pull effort; Said test section comprises gear train and pull and push dynamometer; The rear end of said gear train contacts with the push rod of pull and push dynamometer, also is provided with pointer on the gear train, and correspondence is provided with scale on the base of said pointer below.

Said gear train comprises drive link and the spring guidepost that is connected the drive link rear end, and the push rod front end of said pull and push dynamometer is equipped with pushing block, and said pushing block front end is connected with the spring that can be inserted in the spring guidepost, and said pointer is arranged on the spring guidepost.

The bottom of said pull and push dynamometer is connected with slide block, and the take-up housing on said slide block and the base is slidingly matched, and also is equipped with on the said slide block to make slide block be fixed in take-up housing upper limit screw.

Said fixing part comprises support bar, supporting seat and the rack-mount spacing screw rod on the base, and said support is fixed on the base.

Low price and push-pull effort the most commonly used are taken into account pointer to be loaded on the gear train; Through gear train the power output of actuator is passed to pull and push dynamometer; Utilize pointer and scale to measure delivery stroke simultaneously; Pull and push dynamometer indicates input power simultaneously, can realize measuring simultaneously the power output of actuator and the purpose of delivery stroke like this.And; Because when actuator is installed on the engine; With the gear train of engine also is to be connected through spring; Therefore to utilize spring to connect drive link and pull and push dynamometer also be for the actual working state of Simulation execution device as much as possible, so that data measured satisfies as far as possible accurately requirement really to the utility model.The utlity model has advantage simple in structure, easy and simple to handle, as can to measure actuator power output and delivery stroke, measurement data accuracy good simultaneously; Can't detect actuator power output and delivery stroke before utilizing the utility model thoroughly to solve to dispatch from the factory in the past, thereby influence the problem of the quality of finished product.The actuator power output and the delivery stroke that after the utility model detects, dispatch from the factory meet the demands fully, and qualification rate 100% is applicable to that the power output of various actuators (speed regulating actuator) and delivery stroke detect.

Embodiment

Below in conjunction with accompanying drawing the utility model is further explained:

With reference to Fig. 1 and Fig. 3; Base 1 is provided with fixing part and test section; Said fixing part comprises support bar 2, supporting seat 17 and the support 3 that is installed on the base, and said spacing screw rod 4 vertically passes support 3 (spacing screw rod 4 and support 3 threaded engagement), and said test section comprises gear train and pointer pull and push dynamometer 8; Said gear train comprise front end can with chuck 15 contacts of actuator 14, the drive link 5 that the rear end is connected with spring guidepost 6; Said pointer 12 is arranged on the spring guidepost 6, and correspondence is provided with scale 13 on the base 1 of said pointer 12 belows, and push rod 16 front ends of said pointer pull and push dynamometer 8 are provided with pushing block 18; The front end of said pushing block 18 is connected with and can be inserted in spring and leads 6 springs 7 in post; The bottom of said pointer pull and push dynamometer 8 is connected with slide block 9, and said slide block 9 is slidingly matched with the take-up housing 10 that is positioned on the base 1, also is equipped with on the said slide block 9 to make slide block 9 be fixed on the stop screw 11 on the take-up housing 10; Said drive link 5 can horizontal slip in pilot hole on the support bar 2 or gathering sill, and needs to guarantee the push rod 16 coaxial settings of drive link 5 and pointer pull and push dynamometer 8.

Method of application:

One. the pick-up unit adjustment

Actuator 14 erect place on the supporting seat 17, be provided with highly need assurance actuator 14 chuck 15 can with the preceding end in contact of drive link 5, tighten caging bolt 4 then downwards, caging bolt 4 is pressed on actuator 14 downwards on the base 1; Promote the slide block 9 on the take-up housing 10 then forward gently; Push rod 16 front ends of pointer pull and push dynamometer 8 are inserted on the spring guidepost 6 through the spring 7 that pushing block 18 connects; And contact with it (answering this moment control spring 7 not have compression); At this moment, the stop screw of tightening on the slide block 9 11 is fixed on the take-up housing 10 slide block 9, slowly adjusts the position of pushing block 18, spring 7, spring guidepost 6 and drive link 5 on the pointer pull and push dynamometer once more; Make the two ends of drive link mechanism all can keep fully contacting respectively with between chuck 15 and the spring 7 (requirement, the pointer that spring 7 does not have compression and pointer pull and push dynamometer 8 should remain on zero-bit always).

Two. detection method

During detection; The switch knob of pointer pull and push dynamometer 8 is switched to the TRACK mark; The initial position that pointer 12 on the record spring guidepost 6 is indicated on scale 13; Actuator 14 is connected with the 24V direct supply that has reometer; Open direct supply and it is transferred to and detect required electric current, check the numerical value that on current value that the displacement on the scale 13, reometer show and pointer pull and push dynamometer 8, shows at pointer 12 under this state in the 10s rapidly, cut off direct supply and also write down above-mentioned numerical value.As required, can repeat aforesaid operations same actuator 14 is carried out repeated detection, to reduce the error that waits other factors to produce because of the testing staff.
