Description
Technical field
The utility model relates to a kind of spring processing work, is specifically related to a kind of spring fixed length machine.
Background technology
Mostly existing spring elongation definite length device is a joint spring housing to be connected on a cylinder, then adopts two identical drawing mechanisms to stretch at both ends of the spring.But two ends adopt two drawing mechanisms, the extensibility leading both ends of the spring is inconsistent, and spring center offsets.
If there is the problems referred to above, the overall material of the spring used is uneven, and this will directly cause coefficient of elasticity inaccurate, and under the prerequisite of different deformation amount, the coefficient of elasticity of spring is unstable.For the instrument of precision, according to itself elastic performance of spring unstable, will directly cause instrument serviceability unstable.A kind of open-mouth ruler for measuring minimum range between two braking rail that such as Chinese patent CN202304706 provides, comprise open-mouth ruler main body, handle, stayed mast, mobile contact, fixed contact, digital display rule and spring elongation mechanism, handle is positioned at the centre position of plane in open-mouth ruler main body, digital display rule is placed on the upper plane of open-mouth ruler main body, spring elongation mechanism is positioned at open-mouth ruler body interior, stayed mast is positioned at the below of handle and is connected with spring elongation mechanism, spring tension mechanism is connected with mobile contact, stayed mast controls mobile contact indirectly, the opposite side being positioned at open-mouth ruler main body mobile contact is provided with fixed contact.
As Chinese patent CN202304706, utilize spring carry out the device measured, the instability of spring performance itself directly impact can measure structure.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of spring fixed length machine can carrying out Uniform Tension to spring.
For solving the problems of the technologies described above, the utility model provides following technical scheme:
Spring fixed length machine, comprise frame and be located at locating piece frame being respectively used to two ends, fixing spring left and right, the upper end of described locating piece is equipped with press block, described press block is located at the top of spring, be provided with a wedge above described press block, wedge is inclined-plane towards the surface of two press blocks, and two inclined-planes are symmetrical along the perpendicular bisector of line between two locating pieces, two joint, inclined-planes have angle portion, and described angle portion is located at the lower end of wedge; Described wedge is connected with a hydraulic stem by a connecting rod, and be hinged in the middle part of described connecting rod on fixture, described locating piece is slidably connected in frame.
Adopt the utility model spring fixed length machine, there is following effect:
1, owing to adopting wedge to compress two locating pieces, and wedge is inclined-plane towards the surface of two press blocks, and two inclined-planes are symmetrical along the perpendicular bisector (vertical line on mid point) of line between two locating pieces, so just can exert a force to two locating pieces equivalently.
2, described locating piece is slidably connected in frame, and the resistance that such frame can provide is less, provides reaction force after being mainly stretched by spring itself to wedge; The suffered power at the left and right two ends of spring is comparatively balanced.
3, when spring elongation is to when determining length, hydraulic stem feed-disabling or rollback, be retained between two locating pieces after a period of time by wedge, and the natural length of spring will be changed.Whole process need realizes the control to its length by the control of hydraulic stem.But no matter how hydraulic stem regulates, described wedge all can carry out equivalent action to press block, can not produce the spring of coefficient of elasticity instability.
Further, described fixture is an otic placode being fixed on body of wall, and described hydraulic stem is hinged on connecting rod.
If fixture is located in frame, frame is difficult to provide the space (because connecting rod utilizes lever principle to wedge effect, so connecting rod must have longer length) of installing connecting rod, so select contiguous body of wall as the installation site of otic placode.
Further, described hydraulic stem is by the telescopic sleeving rod of Driven by Hydraulic Cylinder.
Adopt telescopic sleeving rod to belong to a kind of conventional selection in prior art, be easy to realize.
Further, the middle part of described locating piece is slidably connected in frame by keyway cooperation, and each locating piece bottom is all fixed with a block, and described block is fixed on two locating pieces one side in opposite directions.
Avoid spring-return power excessively strong, spring, by the angle portion of press block compressing wedge, makes it compressive deformation; So devise the block be between two locating pieces, for security protection, make to there is certain safe distance between two locating pieces.
