Description
Technical Field
The utility model relates to a device especially relates to a heighten self-lock device, and its mainly used cutting machine cutter altitude mixture control also can be used to occasions such as compressed air pressure adjustment, flow control.
Background
An adjusting mechanism on the existing cutting equipment is mainly self-locked through friction force, and is easy to loosen and poor in reliability particularly in a vibration environment; the generally adopted mechanical structure is that the height is adjusted through a bolt pair, the bolt pair is easy to loosen in a vibration environment, and the structure is unreliable.
The chinese patent publication No. 207814184U, 09/04 in 2018, discloses a utility model named "a tightening type locking bolt pair". The nut comprises a nut body and a holding mechanism which is arranged on one end face of the nut body and can be adjusted to hold the bolt rod tightly; although the patent uses the auxiliary bolt and the nut to be screwed on the bolt rod for fastening, the bolt rod can be tightly embraced by the enclasping mechanism by adjusting the enclasping mechanism, so that the nut is not easy to loosen and the anti-loosening effect is obvious; but the cutting vibration environment is easy to loosen and can not realize self-locking, so the cutting vibration environment has the defects.
Therefore, it is particularly necessary to provide a height-adjusting self-locking device which is not easy to loosen in a vibration environment, has good reliability, and can be adjusted and self-locked.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the above-mentioned not enough that exists among the prior art, and provide a structural design is simple reasonable, and altitude mixture control is reliable and stable, realizes the auto-lock, improves reliability and interchangeability, convenient operation's height-adjusting self-lock device.
The utility model provides a technical scheme that above-mentioned problem adopted is: this heightening self-locking device is including heightening the screw rod and heightening the nut, heightening both matches of screw rod and heightening nut, its characterized in that: the positioning plate is connected with the height-adjusting screw rod, and the positioning pin is contacted with the positioning plate under the action of the spring; the whole structure is simple and reasonable in design, the self-locking rotation freedom degree is realized by adopting the positioning disc and the positioning pin, and the height adjustment is stable and reliable.
As preferred, set up a waist hole in the middle of the positioning disk, the equipartition sets up a plurality of location shrinkage pools on the positioning disk.
Preferably, the flat position of height-adjusting screw head is installed in the waist downthehole in the middle of the positioning disk.
As preferred, the locating pin passes through the spring action and matches with the corresponding location shrinkage pool of positioning disk.
Compared with the prior art, the utility model, have following advantage and effect: overall structure design is simple reasonable, adopts positioning disk and locating pin to come the auto-lock rotation degree of freedom, and altitude mixture control is reliable and stable, and after the cutting bed has increased this device, cutter altitude mixture control does not take place the condition not hard up and running position after certain position, and the reliability obtains improving by a wide margin.

In the drawing, a cutter execution part A, a height-adjusting screw rod 1, a height-adjusting nut 2, a positioning disc 3, a positioning pin 4, a spring 5, a waist hole 6, a positioning concave hole 7 and a flat position 8.
Detailed Description
The present invention will be described in further detail by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and are not intended to limit the present invention.
Examples are given.
Referring to fig. 1 to 4, the self-lock device that increasees of this embodiment includes heightening screw 1, heightening nut 2, positioning disk 3, locating pin 4 and spring 5, and heightening screw 1 matches with heightening nut 2 both, and positioning disk 3 links to each other with heightening screw 1, and locating pin 4 contacts with positioning disk 3 through the effect of spring 5.
A waist hole 6 is arranged in the middle of the positioning disc 3, and a plurality of positioning concave holes 7 are uniformly distributed on the positioning disc 3; the head flat position 8 of the height-adjusting screw rod 1 is arranged in a waist hole 6 in the middle of the positioning disc 3; the positioning pin 4 is matched with a corresponding positioning concave hole 7 of the positioning disc 3 through the action of a spring 5.
The working process of the height-adjusting self-locking device of the embodiment is as follows: heightening screw 1 is fixed on cutter executing part A, heightening nut 2 is rotated, the height of cutter executing part A (namely the cutter) is adjusted, flat position 8 at the head of heightening screw 1 is installed in waist hole 6 in the middle of positioning disc 3, the rotational freedom degree is limited, positioning pin 4 is pushed against the concave hole of positioning disc 3 under the action of spring 5, the rotational freedom degrees of heightening nut 2 and heightening screw 1 are also limited, heightening self-locking action is completed, and the reliability is greatly improved.
This embodiment is through on current structure basis, including positioning disk 3 and locating pin 4 structure, realizes the auto-lock, improves the reliability, satisfies the user demand.
And will be apparent to those skilled in the art from the foregoing description.
In addition, it should be noted that the specific embodiments described in the present specification may be different in the components, the shapes of the components, the names of the components, and the like, and the above description is only an example of the structure of the present invention. All the equivalent changes or simple changes made according to the structure, characteristics and principle of the utility model are included in the protection scope of the utility model.
