Abstract
The utility model relates to the technical improvement to a spring fatigue screening testing device. The testing machine comprises a body, clamp plates arranged in the body and electromagnets arranged in the body, and the number of the electromagnets can be at least two pairs, which can be symmetrically distributed at the upper and lower sides of a drive plate. The drive plate is positioned between the upper and lower clamp plates which are parallel, the ambient edge of the drive plate is provided with a slot, and balance blocks are uniformly embedded in the slot; a machine base is arranged outside the body, and the body is connected mutually with the machine base through an anti-rattler spring below the body. The utility model has the characteristics of simple structure and low cost.
Description
The utility model belongs to a kind of technological improvement to spring fatigue filler test equipment.
The enterprise of professional production spring need carry out Stromeyer test to the spring of producing mostly, and whether the spring of being produced with check meets the requirements.At present, general spring fatigue test machine is broadly divided into two classes both at home and abroad: mechanical type and electromagnetic type.
Wherein, the DV8-S2 type testing machine that mechanical type such as West Germany produce, about 5 kilowatts of driving power, speed reaches 2500 times/minute, can lay 320 springs at every turn, but needs with special starter gear and lubricating system, complex structure, cost height.Another kind of electromagnetic type as the Wuxi 2SS-041B of oil nozzle oil pump factory type testing machine, about 1.5 kilowatts of driving power, speed 3200 times/minute can be placed 224 springs at every turn.Upper and lower two-layer spring-load characteristic is not quite similar, and drive plate is subjected to the spring torsion influence, has the phenomenon of tiltedly shaking.
The purpose of this utility model is the spring fatigue test machine of a kind of simple in structure, cheap, testing machine function admirable of design.
Its main technical schemes comprises body and is installed on intrinsic clamping plate and electromagnet, it is characterized in that electromagnet has two pairs of upper and lower both sides that are symmetrically distributed in drive plate at least, and drive plate is between upper and lower two parallel clamping plate.
The edge of drive plate has groove, is embedded with counterbalance weight in groove equably.At this external organic block, body utilizes antirattle spring and the support below it to interconnect.
The screw rod that the two clamping plates utilization is evenly arranged interconnects, and two sections opposite screw threads of hand of spiral is arranged on the every screw rod, and be connected with upper and lower two clamping plates respectively, is fastenedly connected a handwheel below screw rod.Tried spring and be positioned evenly over the both sides of electromagnet.
The utility model has the advantages that because electromagnet has two pairs of both sides that are symmetrically distributed in drive plate at least, make can place to be tried spring more, test rate is higher, thereby improved production efficiency, simultaneously, because the contact area of electromagnet and drive plate increases, thereby has reduced the influence of spring torsion to drive plate, makes the experimental performance of testing machine better; Offer groove around the drive plate, and after in groove, placing several counterbalance weights equably, can guarantee that all are tried the amplitude uniformity of spring; After between body and support antirattle spring being set, can effectively avoid vibration problems.
Fig. 1 is a structural drawing of the present utility model.
Fig. 2 is the A-A view of Fig. 1.
As shown in the figure: utilize antirattle spring 7 to connect body 8 in the bottom of support 9, the clamping plate 2 that two parallel horizontal positioned are arranged at the middle part of body 8, and utilize two screw rods 5 that it is interconnected, two sections screw threads that direction is opposite are arranged on screw rod 5, respectively with last, the threaded engagement of following two clamping plates 2 connects, be fastenedly connected a handwheel 4 in the lower end of screw rod 5, last, 2 of following two clamping plates have drive plate 3, this drive plate 3 around fluted 11, and in the groove 11 on each limit, settle a counterbalance weight 6 equably, last, following two clamping plates 2 inboards connect two pairs of electromagnet 1 respectively symmetrically, each comprises electromagnet 1, two of following symmetry are tried the both sides that spring 10 is positioned at electromagnet 1.
During work, rotate handwheel, make by screw rod that clamping plate are upper and lower to be moved, make and tried spring and clamp or unclamp, when being rotated counterclockwise handwheel, clamping plate to predetermined value, continue the application of force with length of spring compressed, and clamping plate are fastened.Power supply is to the electromagnet interleaved power, and upper and lower two electromagnet alternately apply electromagnetic attraction to drive plate, make the upper and lower vibration of drive plate, and spring is alternate compression, elongation just.The frequency generation resonance of the elastic system of forming when power supply alternative frequency and drive plate and spring, system just produces resonance, and peak swing appears in drive plate, makes spring also obtain peak swing.The size of this amplitude, relevant with the size of source current and voltage.Drive plate has an amplitude balance system, is made of 4 counterbalance weights, is used for regulating the center of gravity of drive plate, keeps whole spring amplitude uniformities.
