Description
Technical field
The present invention relates to the technical fields of automobile parts assembly tool, specifically disclose a kind of flexure spring mounting device.
Background technique
The application field of spring is very extensive, including the traffic transport industries such as automobile, motorcycle, diesel engine and railway, also
Including daily necessities industry and irommongery, instrument and meter and electric Spring Industry etc..Currently, traffic transport industry is spring application
Most important in field, most promising market.
With the economic development and improvement of people's living standards, people are also being continuously increased the demand of automobile, because
This, automobile manufacture industry is also evolving and improves.In automobile production manufacturing process, for the peace of spring in automobile parts
Dress then mainly uses hand assembled spring.Such as in clutch install contraction spring when, using by hand installation spring to from
In the hole of clutch.And it is slow to pacify spring-loaded speed by hand, influences working efficiency, and for operators, workload is very
Huge, hand is easy injury due to excessively working, unfavorable to the health of operator.In addition, hand assembled can not have
The quality of effect control product, such as it is possible that spring neglected loading or the phenomenon that filling more.
Summary of the invention
The invention is intended to provide a kind of flexure spring mounting device, to solve the above-mentioned installment work of spring in the prior art effect
The low problem of rate.
In order to achieve the above object, base case of the invention are as follows: a kind of flexure spring mounting device, including the first gas
Cylinder, a pair of of fixation wall, a pair of of wedge-shaped catch and a pair of wedge-shaped pushing block.First cylinder is equipped with piston, and the piston is connected with
Spring conductor rod and two piston rods, described two piston rods are located at the two sides of spring conductor rod；The spring conductor rod is to stretch
Contracting bar, and spring conductor rod is equipped with baffle；The pair of fixation wall is arranged by center axial symmetry of spring conductor rod in bullet
Spring guide rod two sides, every side fixation wall are equipped with spring and the second cylinder；The spring is connected with one end of wedge-shaped catch, and two
The other end of wedge-shaped catch offsets, and the part to offset forms wedge-shaped part；Partition is equipped in second cylinder, the partition will
Second cylinder interior is divided into the two chambers communicated；First piston and second piston, institute are respectively equipped in described two chambers
It states first piston to be connected with piston rod, the second piston is connected with connecting rod, and connecting rod is connected with wedge-shaped pushing block.
The working principle of this base case is: flexure spring is set on spring conductor rod, and flexure spring one end is against
On baffle；Spring conductor rod is elongated, spring conductor rod is made to pass through the workpiece position that wedge-shaped part arrives at flexure spring to be installed；First
Cylinder push the spring guide rod moves in the horizontal direction, and flexure spring offsets with wedge-shaped catch；At this point, the first cylinder continues to push away
Dynamic spring conductor rod moves in the horizontal direction, and baffle compressed flexible spring, flexure spring is then provided with elastic-restoring force；?
While one cylinder push the spring guide rod is mobile, piston rod is also moved horizontally, and piston rod pushes the first of the second cylinder
Piston sliding, air-flow pours in another chamber of the second cylinder at this time, pushes second piston sliding, and second piston pushes connecting rod,
Connecting rod makes wedge-shaped pushing block mobile toward wedge-shaped part direction, and final wedge shape pushing block squeezes wedge-shaped part and moves on into wedge-shaped part,
So that two wedge-shaped catch are mobile toward the two sides of spring conductor rod, flexure spring is discharged；Flexure spring is returned using the elasticity of itself
Multiple power, pops up along spring conductor rod, is mounted in workpiece to be installed.After flexure spring is installed, the first cylinder drives spring
Guide rod and piston rod homing, also homing, wedge-shaped catch offset to form wedge-shaped part each components again.
The beneficial effect of this base case is: compared to installing flexure spring by hand, the device in this programme utilizes the
One cylinder also makes the second gas using the first cylinder while push the spring guide rod makes flexure spring obtain elastic-restoring force
Gas in the jar circulates, and changes the direction of transfer of power, realizes the release of flexure spring, make flexure spring pop up and it is automatic
It is installed in workpiece to be installed, shortens the set-up time of flexure spring, improve work efficiency, and reduce operator's
Work the amount of labour.In addition, removing plays a part of being oriented to outside flexure spring installation path since spring conductor rod is telescopic rod,
When flexure spring needs to be installed on axis, spring conductor rod front end offsets with the axis, when cylinder push the spring guide rod, spring
Guide rod offsets with the axis and shrinks, and reduces the installation stroke of flexure spring, saves the set-up time.
Further, the wedge-like tip of the wedge-shaped catch is equipped with arc groove, and the radius of the arc groove is more than or equal to
The radius of spring conductor rod.In this way, clearance fit state is changed by line contact condition between spring conductor rod and wedge-shaped pushing block,
To facilitate the sliding of spring conductor rod, the top of wedge-shaped catch is avoided to scratch spring conductor rod.
Further, the surface of the wedge-shaped catch is equipped with slideway.To facilitate flexure spring sliding on the surface of wedge-shaped catch
It is dynamic.
Further, gasket is equipped in the slideway.It is directly contacted to avoid flexure spring and wedge-shaped catch, scratches wedge shape gear
Block.
Further, the baffle is prepared for flexible material.Flexible material can generate elastic shape when being squeezed
Become restoring force, further provides elastic force for flexure spring.
