Description
Technical field
The utility model relates to mechanical assembly technique fields, and in particular to a kind of elastic cylindrical pin beats pin tooling.
Background technique
Elastic cylindrical pin is also known as spring catch, design feature: a kind of hollow cylindrical body without a head, axially grooved, two head ends
There is chamfering in portion.Elastic cylindrical pin need to have good elasticity and anti-shearing force.Outer diameter need to be than assembly aperture slightly when this kind of pin is chosen
Greatly a bit, pin has shrinkage, while the reaction force after contraction can allow pin tightly to cooperate with inner hole.Be usually used in part it
Between positioning, connection, fixation etc..For elastic cylindrical pin due to smaller, it is manual operations that installation is mostly, operator one hand steered bullet
Property straight pin or clipped with pliers, another hand is driven into location hole with hand hammer, if installation is exerted oneself unevenness by hand,
Elastic cylindrical pin plastic deformation will lead to pin failure；Secondly the safety of operation is poor, and operator is accidentally easy for pounding
When hand, the especially assembly lesser elastic cylindrical pin of length it is easier that this phenomenon occurs.
China Patent No. CN201020601171.7 discloses a kind of assembling device for elastic cylindrical pin, by extension sleeve
Magnet adsorb straight pin, then by squeezing elastic cylindrical pin with the red needle of fixes sleeve sliding connection, but due to elasticity
Straight pin is straight trough open-type, outer circle be not it is very regular, squeezed with red needle, the bad guarantee Elastic Circular in assembling process
The verticality of pin, it may occur that the accident of elastic cylindrical pin abjection reduces working efficiency, secondly magnet installation to a certain extent
In the radial through-hole of extension sleeve, elastic cylindrical pin is straight trough open-type, therefore the magnetic force of open end is lower than other end face, also easily
During causing needle to squeeze elastic cylindrical pin, elastic cylindrical pin offsetting dip not can guarantee elastic cylindrical pin and installation part
Between exact position requirement；Furthermore the device needs external impulsive force device force, is not available when assembly space is narrow,
Applicable surface is narrow.
Utility model content
In view of the deficiencies of the prior art, what the utility model provided a kind of elastic cylindrical pin beats pin tooling, passes through bar shaped
The guiding role of magnet absorption and pilot hole ensure that elastic cylindrical pin free dropping and will not be in always in assembling process
Vertical state improves assembly efficiency and quality.
In order to solve the above technical problems, the following technical solution is employed for the utility model:
A kind of elastic cylindrical pin beats pin tooling, comprising: percussion pin shaft, the sleeve, fixing seat set gradually from top to bottom,
The sleeve is fixedly connected with pin shaft is tapped, and the lower end of the sleeve offers circular through hole and square through hole, described round logical
Hole is connected to square through hole, and bar magnet is equipped in the square through hole, and the fixed seating is connected on the outside of sleeve, passes through spiral shell
Nail is fixed, and the fixing seat bottom end is equipped with circular through hole with the through-hole of diameter and coaxial line.
Further, for the sleeve in up big and down small step-like, the thick step end of the sleeve is hollow tubular, interior
It is machined with the internal screw thread being adapted to percussion pin shaft lower end external screw thread.
Further, plane at symmetrical 4 is machined on the thick step end outer circumference surface of the sleeve.
Further, the upper end for tapping pin shaft is provided with percussion boss, taps the radial dimension of boss not less than set
The radial dimension of cylinder, and the top surface for tapping boss is plane.
Further, the percussion pin shaft is quenched to obtain, to improve hardness.
The beneficial effects of the utility model are:
1. the utility model passes through the cooperation of bar magnet and circular through hole, the verticality of elastic cylindrical pin ensure that, increase
Strong assembly precision；Bar magnet adsorbs elastic cylindrical pin, makes elastic cylindrical pin in assembling process, is close to always round logical
Hole, holding vertically move down, ensure that the concentricity of elastic cylindrical pin and mounting hole in this way, improve assembling quality, and bar shaped
Magnet is identical as circular through hole height, therefore elastic cylindrical pin can be made to be constantly subjected to magnetic force during circular through hole moves down
Attract, guarantees that elastic cylindrical pin will not be popped up because of stress, reduce the probability of happening of industrial accident.
2. in assembling process, elastic cylindrical pin need to be only put into circular through hole by operator, assembled with hand hammer, for
The shorter elastic cylindrical pin of length assembles better effect.
3. the utility model beat pin tooling it is compact and flexible, the volume of tooling is greatly saved, solves in assembly space
When narrow the problem of assembly difficulty.
