Description
Technical field
The present invention relates to a kind of proving installation, particularly relate to a kind of metal connecting piece life detector.
Background technology
Metal connecting piece is used for the consolidation of daily household vapour, connection function, particularly the gate flap support of the garage door pulling force that in use metal connecting piece is subject to repeatedly easily produces fatigue breakdown, therefore certain quantitative requirement is had to the number of times of gate flap support stretching resistance, must test to obtain with endurance testing device the number of times of its stretching resistance to metal connecting piece before the gate flap support of garage door dispatches from the factory, not have special life detector can test the number of times of the gate flap support stretching resistance of garage door easily at present.
Summary of the invention
The technical matters that the present invention solves is: provide a kind of structure simple metal connecting piece life detector, can test the number of times of stretching resistance when metal connecting piece is subject in outside pulling force situation repeatedly easily.
Technical scheme of the present invention is: a kind of metal connecting piece life detector, it is characterized in that, comprise base plate and the air pump being arranged on described plate upper surface, first connecting rod, second connecting rod, first guide rail, second guide rail and the slide block be slidably arranged on the first guide rail, described first guide rail and the second guide rail parallel, one end of described first connecting rod is provided with the clamping part for installing metal connecting piece, this clamping part is arranged on described base plate by rotating shaft, the other end of first connecting rod and one end of described second connecting rod hinged, the other end and the described slide block of second connecting rod are hinged, described slide block is also provided with the extension spring for applying pulling force to metal connecting piece, described second guide rail is bolted first pole changer and the second pole changer with spacing distance, described slide block is mobile between the first pole changer and the second pole changer also can be touched with the first pole changer, the second pole changer respectively, and the first pole changer and the second pole changer are connected to a counter respectively by signal wire, the piston rod end of described air pump and the middle part of described first connecting rod hinged.
Described first pole changer and the second pole changer are connected to an air pressure converter respectively by tracheae.
Described first pole changer and the second pole changer are connected to described air pump respectively by tracheae.
The invention has the beneficial effects as follows: clamping part when the present invention uses, metal connecting piece being arranged on first connecting rod, then the end of the extension spring be connected on slide block is connected with metal connecting piece, after air pump starts, the piston rod of air pump pushes first connecting rod, first connecting rod is around axis of rotation, the end of the first connecting rod rotated is owing to being hinged with second connecting rod, now second connecting rod promotes slide block towards the side's slip away from rotating shaft until touch the second pole changer being positioned at the first guide rail far-end, then the piston rod retraction of air pump, now touching signal is transferred to counter by the second pole changer, while the piston rod retraction of air pump, band movable slider returns and slides and touch the first pole changer, then the piston rod of air pump stretches out, now touching signal is transferred to counter by the first pole changer, extension spring applies pulling force to metal connecting piece in the process, by counter records extension spring, metal is connected to the number of times applying pulling force simultaneously, thus whether testing out metal connecting piece, to bear the number of times of pulling force up to standard, convenient, judge that whether metal connecting piece product is qualified accurately.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
See Fig. 1, Fig. 2, a kind of metal connecting piece life detector, comprise base plate 1 and the air pump 2 being arranged on described base plate 1 upper surface, first connecting rod 3, second connecting rod 4, first guide rail 5, second guide rail 6 and the slide block 7 be slidably arranged on the first guide rail 5, described first guide rail 5 and the second guide rail 6 parallel, one end of described first connecting rod 3 is provided with the clamping part 3 ' for installing metal connecting piece, this clamping part 3 ' is arranged on described base plate 1 by rotating shaft 8, the other end of first connecting rod 3 and one end of described second connecting rod 4 hinged, the other end and the described slide block 7 of second connecting rod 4 are hinged, described slide block 7 is also provided with the extension spring 9 for applying pulling force to metal connecting piece, described second guide rail 6 is bolted the first pole changer 10a and the second pole changer 10b with spacing distance, described slide block 7 is mobile between the first pole changer 10a and the second pole changer 10b also can be touched with the first pole changer 10a, the second pole changer 10b respectively, and the first pole changer 10a and the second pole changer 10b is connected to a counter 11 respectively by signal wire, the piston rod end of described air pump 2 and the middle part of described first connecting rod 3 hinged.Described first pole changer 10a and the second pole changer 10b is connected to an air pressure converter 12 respectively by tracheae, and described first pole changer 10a and the second pole changer 10b is connected to described air pump 2 respectively by tracheae.When the piston rod of air pump 2 shrinks mobile to the right, slide block 7 moves right shake-up first pole changer 10a, because the first pole changer 10a is connected to air pressure converter 12, pneumatic pressure converter 12 make the piston rod of air pump 2 this moment immediately convert moving direction namely stretch out movement left, now slide block 7 is moved to the left shake-up second pole changer 10b, because the second pole changer 10b is also connected to air pressure converter 12, pneumatic pressure converter 12 makes the piston rod of air pump 2 once more change moving direction namely to shrink movement to the right, slide block 2 moves right and again touches the first pole changer 10a, therefore the first pole changer 10a in the present invention, second pole changer 10b and air pressure converter 12 can control the piston rod stretching motion repeatedly of air pump 2 automatically, make slide block about 6 move around to realize extension spring and pulling force is applied to metal connecting piece.When the present invention uses, metal connecting piece 13 is arranged on the clamping part of first connecting rod, then the end of the extension spring be connected on slide block is connected with metal connecting piece, after air pump starts, the piston rod of air pump pushes first connecting rod, first connecting rod is around axis of rotation, the end of the first connecting rod rotated is owing to being hinged with second connecting rod, now second connecting rod promotes slide block towards the side's slip away from rotating shaft until touch the second pole changer being positioned at the first guide rail far-end, then the piston rod retraction of air pump, now touching signal is transferred to counter by the second pole changer, while the piston rod retraction of air pump, band movable slider returns and slides and touch the first pole changer, then the piston rod of air pump stretches out, now touching signal is transferred to counter by the first pole changer, extension spring applies pulling force to metal connecting piece in the process, by counter records extension spring, number of packages web member is applied to the number of times of pulling force simultaneously, thus whether testing out metal connecting piece, to bear the number of times of pulling force qualified, thus it is convenient, judge that whether metal connecting piece product is qualified accurately.
