Detailed description of the invention
For making those skilled in the art better understand the technical solution of the utility model, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Spring fitting fixture in the utility model embodiment realizes spring elongation operation by the relative movement of the clamping part at slide construction clamp springs two ends, realizes follow-up spring fitting in small space.Fig. 1 is the utility model embodiment spring fitting clamp structure schematic diagram, and Fig. 2 is that the utility model embodiment spring fitting fixture is installed and needed schematic diagram after extension spring.
Can find out from Fig. 1 and Fig. 2, the spring fitting fixture of the present embodiment has slide rail 1 and the slide block 3 being arranged on slide rail 1, can only sliding along the bearing of trend of slide rail 1.On one end that two clamping parts are fixedly mounted on slide rail 1 respectively and slide block 3, by slide block 3 relatively slide rail 1 slide and realize the relative movement of two clamping parts.
Found out by Fig. 1, groove shapes be arranged to by slide rail 1, slide block 3 be arranged to fit the O-ring seal form of groove to be socketed on slide rail 1, can along slide rail 1 surface sliding.An end face part of slide rail 1 is provided with relatively-stationary first clamping part 2; Slide block 3 is fixedly installed the second clamping part 4.First clamping part 2 and the second clamping part 4 all have the two ends of jaws for clamp springs, realize the stretching of spring.
Can expect, adopt and arrange the method that slide block 3 drives spring elongation, ARTIFICIAL FORCE or other form External Force Actings, on slide block 3, without the need to using the instrument extension springs such as screwdriver, carry out installation operation comparatively easily.
For improve further extension spring operation convenience, prevent spring retraction from surprisingly bouncing back, adopt the mode moving slider 3 of gears meshing in the present embodiment and form self-locking.As Fig. 1 and Fig. 3, wherein slide rail 1 has bearing block linear gear rack 11, slide block 3 being provided with gear 31, the gear shaft 32 installing gear 31 and undertaking gear shaft 32.Gear shaft 32 is arranged on bearing block, can roll relative to slide block 3; Gear 31 is connected by flat key with gear shaft 32; Gear 31 and tooth bar engagement.When External Force Acting is on gear shaft 32, gear shaft 32 driven gear 31 rotates, and gear 31 and linear gear rack 11 engagement rotation move relative to linear gear rack 11, are moved by power transmission belt movable slider 3 by bearing block.Certainly, the connected mode of gear shaft 32 and gear 31 is not limited to flat key, also can be spline joint or interference fit connection.
Because each contact point when gear 31 and linear gear rack 11 engage is all in path of contact, and path of contact and tooth bar horizontal-extending direction form the angle of engagement, and the elastic recoil power of spring can only the extension side of linearly tooth bar 11, not at the active force perpendicular to tooth bar direction, therefore pinion 31 initiatively cannot be driven to rotate relative to linear gear rack 11, slide block 3 also just cannot be made to move relative to slide rail 1; Achieve the self-locking of slide block 3 at ad-hoc location.
Operate control for convenience, the gear 31 in the present embodiment realizes rotating by manual drive mode.Rocking arm 34 and crank 33 is provided with in one end of gear shaft 32; Rocking arm 34 is fixedly connected with gear shaft 32; Crank 33 drives rocking arm 34 to rotate and just can gear shaft 32 rotate.According to principle of moments, rocking arm 34 is longer, that driven wheel 31 rotates, the external force acted on crank 33 can be less, but crank 33 radius of gyration is larger; In order to reach optimum service efficiency, can according to the length of practical situations determination rocking arm 34.
Certainly, automatic power-actuated form driven wheel 31 also can be adopted in other embodiments to rotate, be fixedly connected with gear shaft 32 as directly arranged motor.
Above-described embodiment turns the form of sliding by rolling and achieves the rotation of slide block 3 relative to slide rail 1, certainly also can adopt to swing to turn the movement that the form of sliding realizes slide block 3.Now, the type of drive of ratchet mechanism can be adopted.
Different from the ratchet mechanism of transmission, ratchet mechanism does not adopt circular ratchet, but the ratchet of lineal layout.Be specially, linear ratchet is arranged on slide rail, slide block is hinged with rocking bar, on rocking bar, is hinged with the ratchet coordinated with ratchet; When rocking bar opposing slider 3 forward swings (when rocking bar moves away from the first clamping part), ratchet is driven to slide on ratchet; When rocking bar is relative to slide block backswing, makes ratchet fasten ratchet and produce active force, the reaction force of ratchet generation simultaneously promotes ratchet and then band movable slider moves.
Above ratchet mechanism is adopted to be only achieve slide block single-way moving, not self-locking.For realizing self-locking, the detent with click-fit also should be set.Detent is also articulated with on slide block, and is pressed on ratchet by holddown spring; When rocking bar forward swings, detent ratchet surface slide and periodically fasten ratchet, prevent rocking bar forward from swinging time slide block under the effect of recoil of spring pulling force, produces reverse movement.
For realizing the slide block return after spring fitting, holddown spring is pulled to make detent and ratchet depart from ratchet surface just slidably slide block.In addition, the annexation also can removed between detent and spring or slide block makes spring lose efficacy and removes detent active force.
It should be noted that owing to may use spring fitting fixture in all angles herein, during use, ratchet need be fitted ratchet surface, therefore under the condition of necessity, also need arrange another spring compression ratchet between ratchet and rocking bar.
According to general knowledge, when the actual tensile elongation of spring exceedes setting maximum tension length, spring lost efficacy or elastic modelling quantity larger change occurs and cannot meet normal work requirements.And when adopting the above spring fitting fixture arranged, operating personnel accurately can not judge whether spring is stretched to correct position.For this reason, also on slide rail 1, limiting component 5 is provided with in the present embodiment.Limiting component 5 is fixed on the ad-hoc location of slide rail 1 by the tensile elongation needed for extension spring.Alert spring fitting operation can be carried out when slide block 3 no longer slides after limiting component 5.
In the present embodiment, limiting component 5 is fixed on slide rail 1 by housing screw 51.Limiting component 5 has screwed hole, and stop screw is arranged in screwed hole and pushes against slide rail 1 by screw thread rotation mode.This is not the spacing sole mode of limiting component 5, and pin fixed form also can be adopted to fix limiting component 5; So, cotter slot or pin hole should be set at the ad-hoc location of slide rail 1; Limiting component 5 also arranges pin hole; Pin is inserted in slide rail 1 through the pin hole on limiting component and achieves a fixed connection.
Aforementioned is only consider how to realize driving slide block 3 to make the second clamping part 4 relative to the mobile problem of the first clamping part 2, for the two ends of spring also should be fastened in the jaws of the first clamping part 2 and the second clamping part 4 by the stretching realizing spring.
The present embodiment adopts the clamping of the method for resilient clamp to need the two ends of extension spring, and the first clamping part 2 is identical with the second clamping part 4 structure.Therefore only the first clamping part 2 is introduced below.For forming jaws, the first clamping part 2 has the fixing right pliers plate of movable left pliers plate 21 22 (described herein be fixed as relatively with the first clamping part 2 or slide rail 1 fixing) and annular shell fragment 23, left pliers plate 21 and right pliers plate 22 hinged.At the bayonet socket 26 that two clamp piece jointed shaft places are provided with cannelure 25 and are communicated with cannelure 25.The two ends of annular shell fragment 23 have plush copper 24.Annular shell fragment 23 to be arranged in cannelure 25 and to make plush copper 24 be connected in bayonet socket 26, size because of cannelure 25 be less than annular shell fragment 23 free time gear 31, the resilience of annular shell fragment 23 makes to push against left pliers plate 21 and right pliers plate 22 outside two plush coppers 24 respectively, make two clamp pieces rotate around jointed shaft and clamp at clamp mouth part.When needing extension spring to operate, external force move left pliers plate 21 form jaws after can mounting spring.
Certainly, adopt elastic component to make the clamping of two clamp pieces form jaws and be not limited to above annular shell fragment 23, also can at the common back-moving spring of two clamp piece arranged outside.Consider the mode of moment loading, back-moving spring should be arranged on the free end of two clamp pieces as far as possible.
It shall yet further be noted that the form of above employing elastic component should ensure that the frictional force between clamping part jaws and spring is greater than the elastic force needing extension spring.
Separately also can adopting other mode fixing springs at clamping part, as adopted the method for pinching screw, using pinching screw to be pressed on two clamping parts by needing extension spring.No matter separately also it should be noted that it is adopt the method for elastic component clamping or the method for pinching screw all should ensure the to be stretched holding portion of spring plastic deformation not to occur, prevent spring strength from reducing.
