Description
Technical field
This utility model relates to the external spring welding procedure structure of a kind of linear electric machine, more specifically, it relates to one
Plant spring Welding Structure.
Background technology
The critical component spring of linear electric machine, owing to vibration cycles number of times needs up to 109, it is easy to produce fatigue disconnected
Splitting, the most how to avoid spring breakage, improving life of product is the problem that producer must solve.Existing spring is formed in one
Structure, because being limited by mould, spring inner gap need to meet mould processing request, and spring inner space exists the most
Waste.Being limited by space, internal stress when spring works is difficult to be reduced to less level, and therefore resisting fatigue is broken simultaneously
Split limited in one's ability.The inventing of Publication No. CN104471848A disclosed a kind of for linear motor on March 25th, 2015
Leaf spring, wherein said spring has interior fastening part, outer fastening part and connects interior fastening part and outer fastening part
Spring arm.Spring arm spirals around the center of area of interior fastening part, and leaf spring is flat in its extension plane, makes
Obtaining the ratio between width and the height of leaf spring of leaf spring and have the value of at least about 1.33, hangs down in the direction wherein measuring height
Directly in the direction measuring width.Specifically, leaf spring can be made up of single sheet material so that interior fastening part, spring arm and outer
Fastening part is integral with one another.But it is relatively low that this leaf spring there is also spring inner space availability ratio, during elastic deformation, inside should
Power is higher, the problem of easy fatigue fracture.
Utility model content
Existing linear electric machine contained spring makes trouble, and is restricted by manufacturing process, and spring inner space availability ratio is relatively
Low, during elastic deformation, internal stress is higher, easy fatigue fracture, and for overcoming these defects, this utility model provides a kind of knot
Structure is simple, and spring inner space availability ratio is higher, internal stress relatively end during elastic deformation, the simplification of indefatigability fracture linear
Motor spring structure.
The technical solution of the utility model is: the linear electric machine spring structure of a kind of simplification, is located at the subiculum of linear electric machine
Between frame and oscillating mass block, this spring structure includes many single spring bars, and single spring bar is respectively arranged at two ends with bottom bracket
Connection strap and oscillating mass block connection strap, the bottom bracket connection strap circular array of all single spring bars is also connected in bottom bracket
On, oscillating mass block connection strap is connected on oscillating mass block.Owing to this spring structure is with linear by many single spring bars
Motor is assembled, the integral type spring contrast processed with existing mould, it is not necessary to limited by mould, not only process more
Easily, and each single spring interspace can control less owing to reducing gap between each spring, inside spring structure
Being fully used in space, can be used to increase the width of spring, improves the mechanical property of spring.
As preferably, single spring bar is curved, and oscillating mass block connection strap is the most curved, and oscillating mass block connection strap
The concave curved portion of concave curved portion and single spring bar be positioned at the same side of single spring bar.Single spring bar and oscillating mass block connect
Bar is the most curved, can be arranged in the shape mated with the space structure between bottom bracket, oscillating mass block, fully profit more easily
Use space.
As preferably, between bottom bracket connection strap and bottom bracket, equal between oscillating mass block connection strap and oscillating mass block
For Welding Structure.Linear electric machine inner space is extremely limited, and fixes bottom bracket connection strap and oscillating mass block by welding manner
Connection strap, structure is the simplest, and space hold is the least.
The beneficial effects of the utility model are:
Reduce linear electric machine spring structure difficulty of processing.This utility model is filled by the relatively simple spring of many root architectures
Join and form, it is not necessary to the spring processing mold that exploitation is complicated, thus handling ease and cost are lower.
Improve the space availability ratio of spring inner.This utility model is assembled, not like integral type by many springs
Spring is limited by mould, and between spring, gap can reduce as far as possible, thus improves the space availability ratio of spring inner.
Improve spring fatigue crack-resistant performance.This utility model is high due to space availability ratio, and the space of saving may be used to add
The width of big spring bar, such spring is in same purpose power, while same deformation, compared with existing spring, it is possible to decrease internal
Stress, reduces the spring failure probability caused because of fatigue damage.

Detailed description of the invention
The utility model is described in further detail for specific embodiment below in conjunction with the accompanying drawings.
Embodiment 1:
As shown in Figure 2 and Figure 3, the linear electric machine spring structure of a kind of simplification, it is located at bottom bracket and the vibration matter of linear electric machine
Between gauge block, this spring structure includes three single spring bars 1, and single spring bar 1 is respectively arranged at two ends with bottom bracket connection strap 2 He
Oscillating mass block connection strap 3, the bottom bracket connection strap 2 of all single spring bars 1 the most equidistantly arranges and is connected in subiculum
On frame, oscillating mass block connection strap 3 is connected on oscillating mass block.Single spring bar 1 is curved, oscillating mass block connection strap 3
The most curved, and the concave curved portion of the concave curved portion of oscillating mass block connection strap 3 and single spring bar 1 is positioned at the same of single spring bar 1
Side.Between bottom bracket connection strap 2 and bottom bracket, between oscillating mass block connection strap 3 and oscillating mass block, it is Welding Structure.
When three single spring bars 1 are with linear electric machine assemble welding, welding position includes bottom bracket solder joint 4, oscillating mass
Block solder joint 5.Test shows, when existing spring is deformed under 1N power effect, internal stress reaches at the two ends of spring
720MPa, and when this spring structure produces the deformation close with existing spring under 1N power effect, internal stress is at spring
Two ends are reduced to 559MPa, and therefore this spring structure is less susceptible to fatigue fracture.
Embodiment 2:
Single spring bar 1 is four.Remaining is with embodiment 1.
