Description

A kind of arc welding gun switch endurance quality test board
Technical field
The utility model relates to a kind of electromechanical equipment of test gas protection welding machine semi-automatic gun switch performance, mainly is applicable to the endurance quality test of arc welding gun switch, belongs to the annex testing apparatus category of welding gear.
Background technology
At present, the test equipment function and the specification of switch are all more complete both at home and abroad, but for the test experiments that only need carry out a kind of simple function; Need not adopt the equipment that has than full functionality to accomplish; On the contrary, simple test only needs to adopt simple equipment just can realize, like this; Both can save expensive installation cost input, and can reach the purpose of test again.
Summary of the invention
The purpose of the utility model is to provide a kind of arc welding gun switch endurance quality test board, and this test board just is based on a kind of equipment of the endurance quality test of Butt welding gun switch, not only simply but also practical.
For realizing that above-mentioned purpose adopts following technical scheme:
A kind of arc welding gun switch endurance quality test board comprises worktable, it is characterized in that: have a motor through securing member be contained in worktable below; Have a hole on the worktable, the output shaft of motor passes this hole and is equipped with a cam, and cam is assemblied on the motor output shaft through key; There are two guide holders to be fixed on the worktable; Have a push rod to pass the center pit of two guide holders respectively, the diameter of push rod is less than the center-hole diameter of guide holder, and push rod can be done rectilinear motion freely under the guide effect of guide holder; One end of said push rod contacts with cam face, and the other end of push rod is provided with clamp device; Compression spring is enclosed within on the push rod, and compression spring one end contacts with a guide holder, and the other end withstands the straight pin that is assemblied on the push rod; The effect of spring is that the end of push rod is closely contacted with the outer round surface of cam.
On said worktable, be equipped with motor output shaft near switch, link to each other with counter near switch, motor rotates a circle, just showing on the counter increases by a circle.
Described motor is provided with speed-regulating switch, is used for controlling rotating speed of motor.
This reality is novel when motor rotates; The outer round surface of cam is owing to the eccentric closely change in location of the push rod of contact generation straight line that makes with it; The moving circle of motor revolution, push rod with regard to to-and-fro movement once, the arc welding gun switch that makes clamped device be held carries out logical and disconnected process once; Through the control of motor speed and motor being rotated the control of the number of turns, just realized the purpose that the switch number of times of Butt welding gun switch is controlled.

Embodiment
Shown in Fig. 1-5, a kind of arc welding gun switch endurance quality test board comprises worktable; Have a motor 3 through securing member be contained in worktable 1 below, have a hole on the worktable 1, the output shaft of motor 3 passes this hole and is equipped with a cam 2; Cam 2 is assemblied on motor 3 output shafts through key, on said worktable 1, also be equipped with motor 3 output shafts near switch, link to each other with counter 10 near switch; Motor 3 rotates a circle; Just showing on the counter 10 increases by a circle, and motor 3 also is provided with speed-regulating switch 9, is used for controlling the rotating speed of motor 3; There are two guide holders 7 to be fixed on the worktable 1; There is a push rod 4 to pass the center pit of two guide holders 7 respectively; The diameter of push rod 4 is less than the center-hole diameter of guide holder 7; Push rod 4 can be done rectilinear motion freely under the guide effect of guide holder 7, an end of said push rod 4 contacts with cam 2 surfaces, and the other end of push rod 4 is provided with clamp device 8; Compression spring 6 is enclosed within on the push rod 4, and compression spring 6 one ends contact with a guide holder 7, and the other end withstands the straight pin 5 that is assemblied on the push rod 4; The effect of spring 6 is that the end of push rod 4 is closely contacted with the outer round surface of cam 2.
Welding gun 11 is held device and grips welding gun 11 belows placement rubber blanket 12 before the utility model test; When the motor generation rotatablely moves; Cam is and then motor generation rotation also, because the exocentric structure of cam, then the distance of push rod end and rotating shaft center produces periodic variation according to certain rules; Because the reacting force of length of spring compressed and the guide effect of guide holder; Push rod just moves reciprocatingly along straight line, when the end of push rod contacts the electric shock switch of welding gun, and switch conduction; Leave the contact switch of welding gun when push rod after, arc welding gun switch breaks off, and the motor revolution is moving once, push rod also thereupon straight reciprocating motion once, the also corresponding make and break process that carries out a time of the switch contact of welding gun.
During test, set the number of times that long duration test needs through counter earlier, regulate rotating speed of motor then and test; When testing time did not reach set point number, counter did not move, and motor is rotated further; Test is proceeded, when testing time reaches set point number, and the counter action; The motor outage, testing experiment stops, thereby realizes the automatic control to the test overall process.
