Abstract
The utility model provides an servomotor coupling mechanism, including piston rod, hookup screw rod, nut and lug, the nut with the lug passes through threaded connection, the hookup screw rod is including the head screw rod, middle part screw rod and the afterbody screw rod that connect gradually, the head screw rod is equipped with screw through-hole, and passes through threaded connection with the piston rod, the afterbody screw rod is equipped with second screw through-hole, and pass through threaded connection with the lug, the rotation direction of screw through-hole and second screw through-hole is opposite, screw through-hole, second screw through-hole and through-hole are on axis with, when the hookup screw rod is rotatory, because the setting of positive and negative screw thread, under the circumstances that the lug does not rotate, can remove about with the rotation of hookup screw rod, after the installation distance of having adjusted the servomotor, screw up nut to second screw through-hole direction, locking hookup screw rod and lug.
Description
Technical Field
The utility model relates to a technical field is connected to the screw rod, mainly used servomotor specifically is kinds of servomotor coupling mechanisms.
Background
The servomotor can be used for a microminiature power station, and has the advantages of small cylinder diameter and compact structure. Generally, the installation distance of the servomotor is not adjusted greatly, but larger deviation sometimes occurs, and the conventional operation needs to unscrew the pin shaft first to screw the lifting lug so as to reduce or enlarge the installation distance, which is too time-consuming.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the technical problem that a connecting mechanism needs to be manually disassembled when the distance between the servomotor and the lifting lug is adjusted in the prior art is solved.
The utility model provides an servomotor coupling mechanism, including piston rod, hookup screw rod, nut and lug, the nut with the lug passes through threaded connection, the hookup screw rod is including the head screw rod, middle part screw rod and the afterbody screw rod that connect gradually, the head screw rod is equipped with screw through-hole, and with the piston rod passes through threaded connection, the afterbody screw rod is equipped with second screw through-hole, and with the lug passes through threaded connection, the rotation direction of screw through-hole with the second screw through-hole is opposite, screw through-hole, second screw through-hole and the through-hole is on the same axis.
When the connecting screw rod rotates, due to the arrangement of the positive threads and the negative threads, the lifting lug can move left and right along with the rotation of the connecting screw rod under the condition that the lifting lug does not rotate, and after the installation distance of the servomotor is adjusted, the nut is screwed to the direction of the second thread through hole to lock the connecting screw rod and the lifting lug.
Since the th threaded through hole and the second threaded through hole are difficult to distinguish under the condition of the same size, the problem is solved by the improvement of the step , specifically, the diameter of the second threaded through hole is larger than that of the th threaded through hole, and the diameter of the through hole is larger than that of the second threaded through hole.
Drawings
The present invention will be further described in with reference to the following drawings and examples.
FIG. 1 is a schematic structural diagram of the present invention
FIG. 2 is a schematic view of the structure of the coupling screw
In the figure, 1 is a piston rod, 2 is a connecting screw rod, 3 is a nut, 4 is a lifting lug, 21 is a head screw rod, 22 is a middle screw rod, 23 is a tail screw rod, 211 is an th threaded through hole, 221 is a through hole, 231 is a second threaded through hole
Detailed Description
The invention will now be described in greater detail with reference to the accompanying drawings, which are simplified schematic drawings that illustrate, by way of illustration only, the basic structure of the invention and, therefore, only show the elements that are relevant to the invention.
As shown in FIG. 1, the utility model discloses an kinds of servomotor coupling mechanisms, including piston rod 1, coupling screw 2, nut 3 and lug 4, nut 3 passes through threaded connection with lug 4, as shown in FIG. 2, coupling screw 2 includes head screw 21, middle part screw 22 and tail screw 23 that connect gradually, head screw 21 is equipped with positive thread through-hole 211, and passes through threaded connection with piston rod 1, tail screw 23 is equipped with reverse thread through-hole 231, and passes through threaded connection with lug 4, the diameter of reverse thread through-hole 231 is greater than the diameter of positive thread through-hole 211, and the direction of rotation is opposite, middle part screw 22 is equipped with the through-hole, the diameter of through-hole 221 is greater than the diameter of reverse thread through-hole 231, positive thread through-hole 211, reverse thread through-hole 231 and through-hole 222 are on the same axis.
The diameters of the two threaded through holes are different, so that the two threaded through holes are convenient for workers to distinguish, and the time is saved; the arrangement of the through hole provides space for adjusting the screw thread; when the connecting screw rod rotates, the lifting lug moves left and right along with the rotation of the connecting screw rod under the condition that the lifting lug does not rotate, and after the installation distance of the servomotor is adjusted, the nut is screwed to the direction of the reverse thread through hole to lock the connecting screw rod and the lifting lug.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
