Description

The automatic internal-and external diameter regulating mechanism of spring

Technical field

The utility model relates to a kind of regulating mechanisms, the specially automatic internal-and external diameter regulating mechanism of spring, belong to spring correction Technical field.

Background technique

Spring is a kind of elastomeric objects for storing mechanical energy.Spring is usually made of spring steel.There are many springs to design.In In routine use, which is commonly referred to as spring.It can control the movement of parts using its elasticity, mitigate impact or shake Dynamic, size of stored energy, measuring force etc..It is widely used in machine, in instrument, spring one end and movable work when installation Part is connected, and the other end is fixed on ground by spring pedestal or another can not be on movable workpiece, so that movable work Part has the effect of bumper and absorbing shock, and spring needs to be corrected according to different needs, and when correction ensures that internal-and external diameter reaches mark Quasi- value.

General spring when correction by the spring after compressing the deformation burnt of high temperature so that the internal-and external diameter of spring is sent out Raw expansion, is adjusted, and traditional regulating mechanism can not reduce the internal-and external diameter of spring, uses inconvenience, and extend bullet By the direct compressed spring top of pressing plate when the internal-and external diameter of spring, leads to spring each section discontinuity, will lead to camber of spring, It influences to use.

Utility model content

The purpose of this utility model is that can not carry out extension spring to solve above-mentioned regulating mechanism reduces spring Internal-and external diameter and spring only have when expanding internal-and external diameter top to be led to discontinuity deformation occurs to influence to use by pressing plate compression Problem and provide spring automatic internal-and external diameter regulating mechanism, have and adjust more convenient, the advantages of spring is unlikely to deform.

The utility model is achieved through the following technical solutions above-mentioned purpose, the automatic internal-and external diameter regulating mechanism of spring, including The spring bracing is installed at the top of pedestal, spring bracing and spring body, the pedestal, and the spring body is socketed in The spy of several internal diameters is set on the side wall that the outer wall of spring bracing, the spring bracing and the spring body fit Push plate is installed in needle, the top of the spring bracing, and the bottom end of hydraulic stem, the hydraulic stem peace are connected at the top of the push plate Mounted in the output end of hydraulic cylinder, the both ends of the push plate are respectively provided with sliding groove, and the inside of the sliding groove is respectively provided with mounting blocks, institute It states mounting blocks and is connected with the sliding groove far from one end of the hydraulic stem by compressed spring, the bottom weldering of the mounting blocks Connect fixing clamp arm, the fixing clamp arm welds several limit plates on the side wall of spring body, between the limit plate Outer diameter probe is respectively mounted inside gap, the outer diameter probe passes through electric wire with the internal diameter probe and is connected with external controller It connects.

Preferably, the spring bracing forms cylindrical structure, and internal diameter probe by two symmetrical support columns It is separately mounted on the outer wall of support column.

Preferably, sliding seat is welded in the bottom of the support column, and two symmetrical slidings are welded on the surface of the pedestal Rail, the support column between sliding seat and pedestal by being movably connected.

Preferably, one end that two sliding seats are located remotely from each other is connected with the output end of electric pushrod, the electricity Dynamic push rod is mounted on the both ends of pedestal.

Preferably, the spacing between two neighbouring limit plates is greater than the spring filament diameter of spring body, and outer Diameter probe is fitted in the surface of spring body.

Preferably, the outer diameter probe is used to incude the outer diameter of spring body, and internal diameter probe is for incuding spring body Internal diameter.

Compared with prior art, the utility model has the beneficial effects that the utility model is easy to use, and it is compact-sized, lead to It crosses and spring body is covered into the push plate that installation can move up and down above spring bracing outer wall, spring bracing, push plate bottom Two fixing clamp arms can sliding laterally are installed, fixing clamp arm is pushed by spring force and close to each other is clipped in spring body On, several limit plates of fixing clamp arm inner wall are stuck in the top and the bottom of every section spring silk of spring body, push plate push when Wait limit plate homogeneous compaction spring, limit plate extension spring when moving up, so that uniform force when spring deformation, spring Spring silk be unlikely to deform, between adjacent limit plate install outer diameter probe, for incude spring body outer diameter variation, spring supporting Frame can be spliced by two support columns, and the sliding seat of support column bottom end controls close to each other or separation by electric pushrod, Support column outer wall that internal diameter probe is installed, for incuding the internal diameter of spring body, therefore can be certainly when the internal-and external diameter of spring is up to standard The dynamic control device stops working.
