The device using method step of detection springs performance is as follows:
1) regulating device: choose the locking hook assembly 20 that size and length is applicable to according to for surveying spring, load in the center pit of main shaft 4, unclamp the dog screw 19 in stroke collision block 18, shift motion collision block 18 vertically, it is the tensile elongation required for surveying spring by the distance adjustment between stroke collision block 18 and spacing flange 17, stroke collision block 18 is fixed on main shaft 4 by screwed in place screw 19, and after correcting, assignment gives the data processor 22 of having started shooting;
2) object hung by dress, pull handle handle: pick up the spring for detecting, its one end is hung on the drag hook of pulling force inductor 21, the other end advances in the crotch of locking hook assembly 20, hold handle-bar grip 15, pull downwards and draw, until the right flank of stroke collision block 18 touches the left surface of spacing flange 17, at this moment also pull motionless with torque wrench handle 15 again, loose one's grip and decontrol handle-bar grip 15;
3) hit enter key, see display screen: the enter key knocking data processor 22, display screen occurs the information of this detection, N (spring code name), Δ L (its length increment), the value of K (stiffness factor of spring);
4) take off object: stir resilience pin, take down the spring detected, knock " N " key of data processor, input is next for surveying spring numbering, puts the spring for detecting;
5) repetitive operation: repeat step 2), 3) and step 4), when the spring that will change different model detects, knock " Y " key, the all information with batch spring have been surveyed in display, knock " N " key again, program is run and is rotated back into input amount of tension Δ L, and operation repeats step 1), 2), 3) and step 4).
The course of work of the present utility model: when wanting detection springs, the locking hook assembly 20 that size and length is applicable to is chosen according to for surveying spring, load in the center pit of main shaft 4, unclamp the dog screw 19 in stroke collision block 18, shift motion collision block 18 vertically, it is the tensile elongation (being defined as preseting length Δ L here) required for surveying spring by the distance adjustment between stroke collision block 18 and spacing flange 17, stroke collision block 18 is fixed on main shaft 4 by screwed in place screw 19, after correction, the numerical value assignment of Δ L is given the data processor 22 of having started shooting.
Pick up the spring for detecting, its one end is hung on the drag hook of pulling force inductor 21, the other end advances in the crotch of locking hook assembly 20, hold handle-bar grip 15, pull downwards and draw, handle-bar grip 15 drives forked connecting rod 7 moving axis 13 that rotates to rotate counterclockwise, moving contact 8 is with by forked connecting rod 7, make two contacts upward sliding in the rail groove of push pedal 9, push pedal 9 one thrust is to the right applied in the process of sliding, push pedal 9 thrust be subject to the right drives main shaft 4 to axially move to the right, main shaft 4 moves right the spring driving locking hook assembly 20 to haul for detecting and moves right, spring for detecting is elongated gradually, while main shaft 4 moves right, also dress stroke collision block 18 has thereon been driven to move right, until the right flank of stroke collision block 18 encounters the left surface of spacing flange 17, stroke collision block 18 retard motion to the right, the main shaft 4 be attached thereto stops moving right, the locking hook assembly 20 being contained in main shaft 4 end also stopped and moves right, at this moment the length be elongated for surveying spring just equals preseting length Δ L, also pull motionless with torque wrench handle 15 again, loose one's grip and decontrol handle-bar grip 15.Rebounded by the spring 3 compressed when main shaft 4 moves right always, promote main shaft 4 to left movement, main shaft 4 drives and is contained in locking hook assembly 20 above it, stroke collision block 18 and push pedal 9 to left movement, restore to the original state gradually for surveying spring, push pedal 9 promotes the contact 8 be contained on forked connecting rod 7, contact 8 is along the rail groove slide downward in push pedal 9, forked connecting rod 7 is made to drive handle-bar grip 15 moving axis 13 that rotates to rotate clockwise, when the shaft shoulder of main shaft 4 contacts the right flank of spacing flange 17, main shaft 4 motion left terminates, and handle-bar grip 15 gets back to original position.
Be elongated to preseting length Δ L gradually for surveying spring, return to gradually again in the whole process of original length, pulling force inductor 21 is always at the pulling force sympathetically suffered by spring, and pass to data processor 22 in real time, data processor 22 calculates the value of device of spring stiffness coefficient K in the operation of spring Performance measurement software, knock the enter key of data processor 22, represent that test terminates, display screen there is the information of this detection, N (spring code name), the value of Δ L (its length increment), K (stiffness factor of spring).
Stir resilience pin 24, take down the spring detected, putting the next spring for detecting, repeating aforesaid operations; When changing different batches, the detection of dissimilar spring, also will again choose locking hook assembly 20, the position of adjustment stroke collision block 18, the numerical value of calibration setup length Δ L, assignment, to data processor 22, puts the spring of next group for detecting.
The course of work of locking hook assembly 20: when the one end for detection springs is advanced in the crotch of locking hook assembly 20, because the design of anti-avulsion bearing pin 23 end is domatic, suffered thrust sector is transmitted vertically, axial thrust makes anti-avulsion bearing pin 23 compress, and little spring 26 moves right, contracting is to room, abdominal cavity 25, domatic end is away from the hook end of main hook body 28, until the passage that the spring carrier arm for detecting is formed from anti-avulsion bearing pin 23 and main hook body 28 enters the crotch of main hook body 28, thrust suffered by anti-avulsion bearing pin 23 is removed, little spring 26 rebounds, promote anti-avulsion bearing pin 23 to left movement, make the end of anti-avulsion bearing pin 23 near the hook end of anti-avulsion bearing pin 23, close the open ports at main hook body 28 crotch place, prevent from deviating from when detecting for surveying spring.
When having detected spring, resilience pin 24 is stirred to the right, anti-avulsion bearing pin 23 is compressed, and little spring 26 moves right, contracting, to room, abdominal cavity 25, takes off tested spring, decontrols resilience pin 24, little spring 26 rebounds, and promotes anti-avulsion bearing pin 23 to left movement, returns to closed state.
