Description

A kind of back-moving spring with fixing hole
Technical field
The utility model relates to spring technical field, is related specifically to a kind of back-moving spring with fixing hole.
Background technology
Along with the development of machinery manufacturing industry, lathe for machinery production gets more and more, then in these mechanical machine tools, the overwhelming majority has liftout attachment, and liftout attachment inside is all provided with back-moving spring, such as punch press, after punch and die have coordinated punching press, need liftout attachment to eject stamping forming stamping parts, so need back-moving spring promote top board, thus make shaping after stamping parts eject die.
And the back-moving spring overwhelming majority of prior art is simply arranged in liftout attachment, back-moving spring can not well be located at liftout attachment, and then use back-moving spring comparatively large at liftout attachment inter deterioration, thus reduce the service life of back-moving spring and the stability in liftout attachment inside.
But for the deficiencies in the prior art, developer be necessary development a kind of reasonable in design, structure simple, comparatively stable in liftout attachment inside, wear extent is less, the back-moving spring with fixing hole of long service life.
Summary of the invention
For solving prior art Problems existing, the utility model object provide a kind of reasonable in design, structure simple, comparatively stable in liftout attachment inside, wear extent is less, the back-moving spring with fixing hole of long service life.
For solving above technical problem, the utility model comes to be realize by the following technical solutions: a kind of back-moving spring with fixing hole, comprises the back-moving spring body being arranged on existing liftout attachment inside;
Described back-moving spring body comprises spring body, and described spring body entirety is cylindrical;
Also comprise and be arranged on spring body one end and the upper insertion rod cooperatively interacted with existing upper patchhole and be arranged on the other end and the lower insertion rod that cooperatively interacts of existing lower patchhole;
Described lower insertion rod offers fixing hole, and described fixing hole and existing fixed bar cooperatively interact, and it are fixed on firmly on existing liftout attachment.
In a preferred embodiment of the present utility model, described spring body, upper insertion rod and the one-shot forming of lower insertion rod bonding jumper.
In a preferred embodiment of the present utility model, described spring body and upper insertion rod are that circular arc is excessively connected.
In a preferred embodiment of the present utility model, described spring body and lower insertion rod are that circular arc is excessively connected.
In a preferred embodiment of the present utility model, described spring body everywhere pitch is all identical.
The beneficial effects of the utility model are; Compared with prior art, the utility model is located at the back-moving spring body of existing liftout attachment inside; Back-moving spring body comprises spring body, and spring body entirety is cylindrical; Also comprise and be arranged on spring body one end and the upper insertion rod cooperatively interacted with existing upper patchhole and be arranged on the other end and the lower insertion rod that cooperatively interacts of existing lower patchhole; Lower insertion rod offers fixing hole, but fixing hole and existing fixed bar cooperatively interact, and then it is fixed on existing liftout attachment firmly, thus avoid the wearing and tearing that back-moving spring relative movement on liftout attachment causes, also improve the stability of back-moving spring on liftout attachment simultaneously.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is one of assembling schematic diagram of the utility model and liftout attachment;
Fig. 3 is the assembling schematic diagram two of the utility model and liftout attachment;
Numeral and the corresponding component title represented by letter in figure:
1. go up insertion rod 2. spring body 3. times insertion rod 4. fixing hole 5. bonding jumpers 6. to have fixed bar 100. and have liftout attachment 200. back-moving spring body.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
Shown in Fig. 1-Fig. 3, the utility model is a kind of back-moving spring with fixing hole, comprises the back-moving spring body 200 being arranged on existing liftout attachment 100 inside.
In the present embodiment, back-moving spring body 200 comprises spring body 2, and spring body 2 is overall cylindrical, and spring body 2 everywhere pitch is all identical, thus it is comparatively even to make each place of back-moving spring receive pressure, and then improves the service life of back-moving spring.
Also comprise in the present embodiment and be arranged on spring body 2 one end and the upper insertion rod 1 cooperatively interacted with existing upper patchhole and be arranged on the other end and the lower insertion rod 3 that cooperatively interacts of existing lower patchhole, and spring body 2 is excessively connected for circular arc with upper insertion rod 1, spring body 2 is excessively connected for circular arc with lower insertion rod 3, thus avoid the larger destruction of bringing to back-moving spring of right angle connection stress, thus improve the mechanical strength of back-moving spring.
In the present embodiment, lower insertion rod 3 offers fixing hole 4, fixing hole 4 and existing fixed bar 6 cooperatively interact, and it are fixed on existing liftout attachment firmly, thus improve the stability of back-moving spring on liftout attachment.
Spring body 2, upper insertion rod 1 and lower insertion rod 3 bonding jumper 5 one-shot forming in the present embodiment, thus further increase mechanical strength and the stability of back-moving spring entirety.
The utility model is located at the back-moving spring body of existing liftout attachment inside in sum; Back-moving spring body comprises spring body, and spring body entirety is cylindrical; Also comprise and be arranged on spring body one end and the upper insertion rod cooperatively interacted with existing upper patchhole and be arranged on the other end and the lower insertion rod that cooperatively interacts of existing lower patchhole; Lower insertion rod offers fixing hole, but fixing hole and existing fixed bar cooperatively interact, and then it is fixed on existing liftout attachment firmly, thus avoid the wearing and tearing that back-moving spring relative movement on liftout attachment causes, also improve the stability of back-moving spring on liftout attachment simultaneously.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
