Technical field
The utility model is related to spring detection device technology fields, more particularly to a kind of to be used for what spring lateral stiffness was tested
Auxiliary device.
Background technology
The lateral stiffness of spring is an important indicator for weighing spring-mass.
Substantially spring lateral stiffness testing machine, testing machine mainly wraps used by existing spring lateral stiffness measures
Include three platen, lower support plate and transverse moving mechanism parts.Test method is：Spring is placed on lower support vertically
On plate, then the upper platen of control is pushed applies static axial force F to spring, then controls lower support plate by transverse moving mechanism
It is deviated to the positive direction of the y-axis of x-y plane, offset is from 0 to rA1When, measure corresponding cross force QA1；Offset is from rA1To rB1
When, measure corresponding cross force QB1, then control lower support plate and be returned to equilbrium position, then control lower support plate to x-y plane
Negative direction of the y-axis offset, offset is from 0 to rA2When, measure corresponding cross force QA2, offset is from rA2To rB2When, it measures and corresponds to
Cross force QB2, then according to formula：Kj=（（QB1-QA1）/（rB1-rA1）+（QB2-QA2）/（rB2-rA2））÷ 2 can be calculated
Lateral stiffness value.
But in measurement process, upper platen remains stationary as, only lean on lower support plate move, lower support plate rely primarily on and
Frictional force between spring drives spring to deviate, and sliding is easy to happen between spring and lower support plate, causes to deviate numerical quantity
Deviation occurs, to which last calculated numerical value can be caused inaccurate.

Specific implementation mode
The utility model is described in further detail below in conjunction with attached drawing.
As shown in Figure 1, a kind of auxiliary device for the test of spring lateral stiffness, including one piece of circular substrate 1, in base
The center location setting of 1 upper surface of plate is additionally provided with three in circular hole there are one the circular hole for processing in the upper surface of substrate 1
The inverted T shaped groove 2 of spaced set in circumferential direction, three inverted T shaped grooves 2 are all along the radial direction setting of substrate 1.Also, in substrate 1
Upper surface is additionally provided with multiple annular shallow slots 8 concentric with it to eliminate its internal stress.
Connection bolt 3 is embedded in inverted T shaped groove 2, the nut portion of connection bolt 3 is rectangle, and inverted T shaped groove 2
Sipes part groove width be more than connection bolt 3 nut portion maximum width, the groove depth of the sipes part of inverted T shaped groove 2 is big
In the thickness of the nut portion of connection bolt 3 so that connection bolt 3 is in slot when moving, need not always with cell wall it
Between rub, consequently facilitating mobile connection bolt 3.
Abutting block 5 is threaded on connection bolt 3 to be pushed against by abutting block 5 when testing spring 4 to be measured
Spring 4 to be measured be fixed with prevent spring 4 to be measured test when substrate 1 between slide.Spiral shell is gone back on connection bolt 3
Line is connected with fixing nut 6, and when fixing nut 6 screws, the nut portion of connection bolt 3 is pushed against the ladder cell wall of inverted T shaped groove 2
On, fixing nut 6 compresses hungry abutting block 5 on the top surface of the substrate 1, to which the position for pushing against block 5 be fixed.
Fixed spring 4 to be measured is pushed against in order to facilitate block 5 is pushed against, pushes against block 5 for pushing against the transversal of 4 side of spring to be measured
Face setting then pushes against block 5 when pushing against spring 4 to be measured and being fixed, pushing against block 5 can ensure there are 2 points of abuttings in order to V-shaped
Spring 4 to be measured facilitates and determines whether the position for pushing against block 5 glances off, to facilitate institute when determining that spring 4 to be measured is pushed against
Locate position.Horizontal stripe teeth 7 is additionally provided with to block spring to be measured on pushing against the one side that block 5 is used to push against spring 4 to be measured
4, enhancing pushes against abutting ability of the block 5 to spring 4 to be measured, is slided to prevent from pushing against between block 5 and spring to be measured 4.
Since the size of spring 4 to be measured is had nothing in common with each other, so the position for adjusting abutting block 5 is needed to carry out spring 4 to be measured
It is fixed, and to ensure that the certain surface for pushing against block 5 can be accurately pushed against on spring 4 to be measured, so also in the following table for pushing against block 5
Face is provided with the limited block 9 being slidably connected in inverted T shaped groove 2, passes through the position-limiting action of limited block 9 so that pushing against block 5 cannot send out
Raw rotation, so that when abutting block 5 is moved along inverted T shaped groove 2, certain surface can be directed at spring 4 to be measured always.
When the lateral stiffness to spring 4 to be measured is tested, substrate 1 is fixed in lower support plate, and substrate 1 is by be measured
Reaction when spring 4 to be measured deviates when the power and substrate 1 that spring 4 pushes are with lower support plate transverse shifting to substrate 1
Power, so only be used to be embedded the locating piece 10 positioned in lower support plate provided with several in the lower surface of substrate 1, to
Facilitate the installation and removal of substrate 1.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can as needed make the present embodiment the modification of not creative contribution after reading this specification, but
As long as all being protected by Patent Law in the right of the utility model.
