Abstract
The utility model relates to Engine Block Test and inspection technology field.This testing apparatus comprises by stand, cylinder, has the accelerator that two pulleys are formed, traction rope, gathering sill, control box, and travel switch is formed; Wherein stand comprises cylinder mounting plane and engine mounting plane, and bearing diagonal, and control box comprises gauge tap sum counter, and principle utilizes cylinder and pulley blocks to pull engine primer.Control pulling rope length with travel switch, record starter endurance life with counter.The utility model can improve and pulls speed, and simulating hand draws start rope; Control pull distance, after preventing engine rope from all pulling out, form dead point, and automatically can record and pull number of times.
Description
Technical field
The utility model relates to Engine Block Test and inspection technology field.Mainly for the endurance life of small-sized hand pulling starter.
Background technology
General Requirements starter is not less than 5000 times-10000 times endurance life.If with manually drawing starter, labour intensity is very big.Existing two schemes replaces manual operation at present, and one utilizes swing-bar mechanism, is tied up on fork by engine start rope.Fork rotates, and drives start rope pull-out and puts back to.Another kind directly draws start rope with cylinder, only has a pulley rotation.
But there is following defect in current two schemes.1. can not determine the length of pull-out.2. fork can not ensure the direction that stay cord pulls out.3. the power of fork pull-out is too large, accurately can not reflect the actual endurance life of start rope.4. can not count.5. the speed pulling out start rope can not with artificial coupling, than artificial pull-out speed slow about 1/2.
Utility model content
In order to solve the problems of the technologies described above, the utility model devises a kind of engine primer durability test desk, to solve the defect that prior art exists.
The technical solution of the utility model is: this test board comprises stand, speed increasing mechanism and control device composition, described stand comprises cylinder mount frame and motor mounts, described speed increasing mechanism comprises traction rope, fixed pulley, travelling block and cylinder, fixed pulley is fixedly installed on cylinder mount frame, travelling block is fixed on cylinder push-rod front end, cylinder is fixedly installed on cylinder mount frame, described traction rope is wire-wrapped on two pulleys, traction rope lower end connects engine starting handle, the other end is fixed on cylinder mount frame, described control device comprises control box, cylinder, counter and two travel switches, control box respectively with cylinder, two travel switch electrical connections, counter is electrically connected with two travel switches, described two travel switches are installed on cylinder respectively.
This test board also comprises cylinder guidance mechanism, and described cylinder guidance mechanism comprises guide plate and guide pole, and guide plate is provided with gathering sill, and guide pole is fixed on cylinder push-rod front end and is through in gathering sill.
Described two travel switches are stroke sensor.
Bearing diagonal is provided with between described cylinder mount frame and motor mounts.
The beneficial effects of the utility model are: the utility model engine primer durability test desk: by adjusting the distance of two travel switches, control the length of pull-out start rope.The distance that pull-out length equals 2 times; Secondly, the direction of start rope is controlled by the pulley position of fixing completely, so can control the direction of stay cord; Moreover the power of pull-out can be controlled by the air pressure of cylinder; And there is counter can accurate metering stay cord number of times.Finally, the speed of pulling force is two speeds of cylinder rectilinear motion, can simulate the state of manual stay cord completely.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As Fig. 1-3 shows: the utility model test board comprises stand, speed increasing mechanism and control device composition, stand comprises cylinder mount frame 1 and motor mounts 10, speed increasing mechanism comprises traction rope 6, fixed pulley 7, travelling block 5 and cylinder 3, fixed pulley 7 is fixedly installed on cylinder mount frame 1, travelling block 5 is fixed on cylinder 3 push rod front end, cylinder 3 is fixedly installed on cylinder mount frame 1, traction rope 6 is wire-wrapped on two pulleys, traction rope 6 lower end connects engine starting handle, and the other end is fixed on cylinder mount frame 1.
Control device comprises control box 11, cylinder 3, counter 12 and two travel switches 2, travel switches 4, control box 11 is electrically connected with cylinder 3, two travel switches 2, travel switches 4 respectively, counter 12 is electrically connected with two travel switches, and two travel switches 2, travel switches 4 are installed on cylinder 3 respectively.
This test board also comprises cylinder guidance mechanism, and cylinder guidance mechanism comprises guide plate 13 and guide pole 14, and guide plate 13 is provided with gathering sill 15, and guide pole 14 is fixed on cylinder push-rod front end and is through in gathering sill 15.The setting of guide plate 13 can make cylinder push-rod lead when push-and-pull, prevents it from offseting.
Two travel switches 2, travel switches 4 are stroke sensor, by stroke sensor control cylinder stretching distance, and sensing data can be passed to rolling counters forward.
Be provided with bearing diagonal 9 between cylinder mount frame 1 and motor mounts 10, bearing diagonal 9 can strengthen the intensity between cylinder mount frame and motor mounts, provides stand in cylinder larger tensile strength when stretching.
Principle of work of the present utility model is:
Engine primer 8 (selecting chain saw engine primer to be example in embodiment) to be installed on motor mounts 10 and fixing, with traction rope 6 connecting engine starting handle.Adjust two travel switches 2 (stroke sensor), travel switch 4 (stroke sensor) distance on cylinder 3.Adjustment cylinder 3 admission pressure.Starting switch, cylinder 3 meeting pulling traction rope 6, and then drive the starting handle of engine 8.When cylinder piston moves to the travel switch 2 of A position, A position travel switch 2 by information feed back to control box 11, the counter motion of control box 11 control cylinder 3.Engine starting handle return.When cylinder piston moves to the travel switch 4 of B position, B position travel switch 4 by information feed back to control box 11, control box 11 control cylinder post-tensioning once more.Iterative cycles like this draws starter.
And counter 12 is according to the signal of two travel switches, the number of times pulled can be recorded.
The above is only preferred implementation of the present utility model, for those skilled in the art, under the prerequisite not departing from the utility model principle, can also make some improvement, and these improvement also should be considered as protection domain of the present utility model.
