When adopting technique scheme, by rotating handwheel, rotating screw bolt, realizes moving up and down of screw rod.The pressing plate that screw rod rotated down connects is placed in suitable height, and operation stationary jaw and floating claw are separately fixed at the upper and lower side of valve spring, are fixed valve spring.After fixing, by rotating handwheel, operated clamp presses down, and because pressing plate is slidably arranged on guide pole, can only slide up and down along guide pole.Because valve spring fixes on pressing plate, by pressing plate, valve spring is compressed, and then reach the object of detection.After having operated, reverse rotation handwheel, lays down the pressure on valve spring after pressing plate being moved to certain position, unclamp floating claw and stationary jaw, take off valve spring.
Further prioritization scheme, the bottom of described screw rod is T-shaped head, described pressing plate offers the T-slot coordinated with T-shaped head.Above-mentioned setting can realize relative motion and the function of screw rod and pressing plate by simple structure.
Further prioritization scheme, is provided with three floating claws below described pressing plate, described base is provided with three stationary jaws.Three floating claws and three stationary jaws are set, good fixation can be played to valve spring on the one hand, moreover the quantity of claw is also unsuitable too much or very few.
Further prioritization scheme, described guide pole is provided with scale.The amount of movement that scale intuitively can see pressing plate is set, simple and convenient.
Further prioritization scheme, is provided with the boss in insertion valve spring below described pressing plate.During operation, by boss insertion valve spring, coordinate floating claw to carry out the spacing of horizontal direction to valve spring, the acting force that floating claw is subject to can be reduced.
Further prioritization scheme, described base is provided with the limiting stand in insertion valve spring.During operation, by limiting stand insertion valve spring, coordinate stationary jaw to carry out the spacing of horizontal direction to valve spring, the acting force that stationary jaw is subject to can be reduced.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model valve spring fixing device for experiment embodiment.
Reference numeral: base 1, pole 2, cross bar 3, nut 31, guide pole 4, pressing plate 5, floating claw 51, stationary jaw 11, valve spring 6, depression bar 7, handwheel 71.
Embodiment
As shown in Figure 1, the utility model valve spring fixing device for experiment, comprises base 1, base 1 is fixed with vertical pole 2, and pole 2 top is welded to connect the cross bar 3 of level, is formed the space frame structure of rectangle by pole 2 and cross bar 3.Also be fixed with vertical guide pole 4 between cross bar 3 and base 1, the top of guide pole 4 is fixed on cross bar 3.Guide pole 4 is positioned at the inner side of pole 2, guide pole 4 is slidably connected with pressing plate 5.Pressing plate 5 has been rotationally connected a depression bar 7 by needle bearing, and depression bar 7 bottom is T-shaped head, pressing plate offers the T-slot coordinated with T-shaped head, makes depression bar 7 that dynamic pressure plate 5 can be with to slide up and down along guide pole 4.The upper end of depression bar 7, through cross bar 3, is run through at the middle part of cross bar 3 and is fixed with a nut 31, depression bar 7 is processed with screw thread, depression bar 7 through nut 31 and with nut 31 threaded engagement.Be fixed with a handwheel 71 on the top of depression bar 7, depression bar 7 can be driven to rotate by rotating handwheel 71, and then make depression bar 7 can with the nut 31 on cross bar 3 for benchmark moves up and down.The below of pressing plate 5 is provided with three floating claws 51; Floating claw 51 is bolted on pressing plate 5 by vertical.Unclamping bolt by rotating, making floating claw 51 around screws, and then the position of floating claw 51 can be adjusted, make it clamp and fix valve spring 6.After the adjustment of position, tight a bolt by rotating, floating claw 51 is fixed on clip position.Inner side base 1 being positioned at guide pole 4 is also provided with three stationary jaws 11.Stationary jaw 11 is bolted on base 1.Unclamping bolt by rotating, making stationary jaw 11 around screws, and then the position of stationary jaw 11 can be adjusted, make it clamp and fix valve spring 6.After the adjustment of position, tight a bolt by rotating, stationary jaw 11 is fixed on clip position.Floating claw 51 and stationary jaw 11 are symmetrical arranged with the vertical center line of pressing plate 5 respectively.This setting can ensure that the valve spring 6 clamped is positioned at the center of pressing plate 5, prevents because the problem of physical dimension, valve spring 6 unbalance stress in the process of experiment.Guide pole 4 is provided with scale.The amount of movement that scale intuitively can see pressing plate is set, simple and convenient.The boss in insertion valve spring is provided with below pressing plate 5.During operation, by boss insertion valve spring 6, coordinate floating claw 51 pairs of valve springs 6 to carry out the spacing of horizontal direction, the acting force that floating claw 51 is subject to can be reduced.Base 1 is provided with the limiting stand in insertion valve spring 6.During operation, by limiting stand insertion valve spring 6, coordinate stationary jaw 11 pairs of valve springs 6 to carry out the spacing of horizontal direction, the acting force that stationary jaw 11 is subject to can be reduced.
During use, first the height and position of stationary jaw 11 is adjusted, then valve spring 6 bottom is placed on stationary jaw 11 makes it be gripped.Again the top of valve spring 6 is arranged on floating claw 51 and is fixed, time fixing, make the end face of valve spring 6 withstand on the lower surface of pressing plate 5.Operation handwheel 71, drives depression bar 7 rotate and move up and down.Under the drive of depression bar 7, pressing plate 5 also moves up and down.When pressing plate 5 moves down, valve spring 6 compressive deformation is made by pressing plate 5 tube squeezing valve spring 6, due under the constraint of stationary jaw 11 and floating claw 51, valve spring 6 can not move or swing by occurred level, can only vertically compress, and then can experimental data be gathered, detect its mechanical property.
In the utility model, by rotating handwheel 71, rotating depression bar 7, realizing moving up and down of depression bar 7.The pressing plate 5 that depression bar 7 rotated down connects is placed in suitable height, and operation stationary jaw 11 and floating claw 51 are separately fixed at the upper and lower side of valve spring 6, are fixed valve spring 6.After fixing, by rotating handwheel 71, operated clamp 5 presses down, and because pressing plate 5 is slidably arranged on guide pole 4, can only slide up and down along guide pole 4.Because valve spring 6 fixes on pressing plate 5, compressed by pressing plate 5 pairs of valve springs 6, and then reach the object of detection.After having operated, reverse rotation handwheel 71, lays down the pressure on valve spring 6 after pressing plate 5 is moved to certain position, unclamp floating claw 51 and stationary jaw 11, take off valve spring 6.
Above is only preferred implementation of the present utility model; should be understood that; for a person skilled in the art; without departing from the concept of the premise utility; some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
