Abstract
The utility model discloses an offsetting spring structure which comprises a spring and a guide rod. The offsetting spring structure is characterized in that an adjusting collar penetrates through the lower end of the guide rod, can move along the guide rod and is fixed corresponding to the guide rod, and a support block penetrates through the upper end of the guide rod, and the spring penetrates through the guide rod and is arranged between the adjusting collar and the support block. In the offsetting spring structure, the spring penetrates through the guide rod so that the motion of the spring is guided, and the direction of restoration motion is ensured; the adjusting collar is arranged at the lower end of the guide rod, and thus positions can be adjusted according to practical conditions to further change the compressive deformation of the spring so as to change the elasticity of the spring, ensure the accuracy of the restoration motion and reduce the energy consumption.
Description
Technical field
The utility model relates to a kind of device of realizing mechanical return, relates in particular to a kind of structure of Returnning spring.
Background technique
In the machinery, use the device that makes the machinery realization reset through regular meeting, such as, the machined components of horizontal reciprocating movement, it can realize that parts move by Electric actuator between the position of two settings; And some reciprocating in vertical direction main equipments also are by taking Electric actuator to realize that it moves between the position of two settings.The said equipment has strict demand to two desired locations that parts arrive, and therefore, must control by Electric actuator.
Need to-and-fro motion for some, the equipment that but reciprocating scope is not had strict demand, more be by taking elastic element, for example, between equipment and reciprocating another endpoint location, spring is set, like this, when needs equipment during to the motion of another end points, an external force is provided, and equipment overcomes spring force and moves under external force; And when needing equipment to return, then only rely on the elastic force of spring.The advantage of this kind equipment is simple in structure, and is cheap, but shortcoming also is apparent in view, as: because the lasting use of spring can cause elastic force to change, and then make reciprocating equipment return inaccurate; Have to be exactly, the existing spring reset structure that adopts all is directly both ends of the spring to be fixed on endpoint location and the equipment usually again, and the reseting movement of equipment can't lead, and of a specified duration resetting is prone to deviation.
The model utility content
The purpose of this utility model provides a kind of Returnning spring structure of simple in structure, elasticity adjusting, to overcome the shortcoming of prior art.
Returnning spring structure described in the utility model, comprise a spring, also comprise a guide rod, an adjustment sleeve is run through in described guide rod lower end, this adjustment sleeve can move and relative fixed with it along guide rod, a support block is run through in described guide rod upper end, and described spring is through this guide rod, and places between adjustment sleeve and the support block.
In the Returnning spring structure described in the utility model, described guide rod top is a boss, and described support block is between this boss and spring.
In the Returnning spring structure described in the utility model, described guide rod bottom has screw thread.
In the Returnning spring structure described in the utility model, described guide rod lower end has screw thread, and described adjustment sleeve is threaded with this guide rod.
In the Returnning spring structure described in the utility model, described guide rod lower end has a plurality of locating slots, and described adjustment sleeve offers positioning hole, and a locating column runs through described positioning hole and inserts in the locating slot.
In the Returnning spring structure described in the utility model, described support block and guide rod surface of contact are provided with self oiling bearing.
In the Returnning spring structure described in the utility model, be provided with between described boss and the support block and compress lining ring.
In the Returnning spring structure described in the utility model, the described lining ring that compresses is fixedly connected on support block.
In the Returnning spring structure described in the utility model, spring can make the spring motion be led to some extent through guide rod, has guaranteed the directivity of reseting movement; And the adjustment sleeve that is provided with in the guide rod lower end then can carry out position regulation according to actual use condition, and then the compressive deformation of spring is changed, thereby changes the elastic force of spring, has guaranteed the accuracy of device reset motion, and has had the minimizing energy consumption concurrently.
Description of drawings
Fig. 1 is the structural representation of Returnning spring structure described in the utility model.
Embodiment
Those skilled in the art below in conjunction with accompanying drawing Returnning spring structure described in the utility model are described further, so that can implement after reading this specification according to this.
As shown in Figure 1, Returnning spring structure described in the utility model comprises:
The upper end of described guide rod 6 is through a support block 2, this support block 2 and guide rod 6 relative fixed.
The lower end of described guide rod 6 is through an adjustment sleeve 4, and this adjustment sleeve 4 can move and relative fixed with it along guide rod 6, and described spring 3 is placed between adjustment sleeve 4 and the support block 2.
Because spring 3 is through guide rod 6, therefore, its to-and-fro motion is led to some extent, guaranteed reciprocating directivity, and, in actual use, the particular location can regulate of adjustment sleeve 4 on guide rod 6, like this, the amount of deformation of spring 3 also can change thereupon, thereby realizes the elastic force of spring 3 is regulated.
In the Returnning spring structure described in the utility model, boss 1 can be arranged in the top of guide rod 6, and described guide rod 6 runs through support block 2, run through spring 3 again, that is to say that support block 2 realizes spacing to support block 2 by the boss 1 that is provided with between boss 1 and spring 3.
At the surface of contact of described support block 2 with guide rod 6, also be the inside of support block 2, self oiling bearing 7 can be set.
Can be provided with between described boss 1 and the support block 2 and compress lining ring 8.And the described lining ring 8 that compresses is fixed with support block 2.
Returnning spring structure described in the utility model can be applied in the various machinery, when reality is used, usually guide rod 6 is connected with described machinery, for this reason, can screw thread be set in the bottom of guide rod 6.As the machinery among Fig. 19, the through hole on the machinery 9 is passed in the bottom of described guide rod 6, again with nut 5 with itself and machinery 9 relative fixed.
In the Returnning spring structure described in the utility model, the position of described adjustment sleeve 4 on guide rod 6 can be regulated.Its concrete mean of calculating has multiple, such as, in the lower end of guide rod 6 screw thread is set, and adjustment sleeve 4 is connected with guide rod 6 by internal thread.For another example, in the lower end of guide rod 6 a plurality of locating slots are set, and positioning hole is set on the described adjustment sleeve 4, make a locating column run through described positioning hole again, and insert locating slot, thus the position regulation and the location of realizing adjustment sleeve 4.
Returnning spring structure described in the utility model, realize spring 3 reciprocating guiding by guide rod 6, and the adjustment sleeve 4 that is provided with on the guide rod 6, adjusted position according to actual needs then, and then the elastic force of Regulation spring 3, guaranteed that device reset is accurate, and made the equipment work that resets, reduced the consumption of energy in resonance point.
