By adopting the technical scheme, a more reliable and convenient connection mode between the piston rod and the hanging head is realized.
Description
Technical Field
The utility model belongs to the technical field of the hydraulic cylinder technique and specifically relates to a connection structure of piston rod and hanging head.
Background
The existing hydraulic cylinder piston rod and the hanging head are directly connected by screwing threads, and the hanging head cannot be screwed down from the piston rod during maintenance due to thread seizure caused by corrosion or uneven stress and the like when the hydraulic cylinder piston rod and the hanging head are actually used (especially large-diameter threads). Finally, only one of the piston rod or the hanging head can be selected for scrapping treatment.
There is therefore a need for an improved connection between a piston rod and a suspension head.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: in order to solve the problems of the prior art in the background art, an improved connection structure of a piston rod and a suspension head is provided.
The utility model provides a technical scheme that its technical problem adopted is: a connecting structure of a piston rod and a hanging head comprises a piston rod, a connecting block and a hanging head, wherein the piston rod and the hanging head are connected through the connecting block; the left end and the right end of the connecting block are respectively provided with a first fastening nut and a second fastening nut, the connecting block, the first fastening nut and the second fastening nut are all split nut structures, and the connecting parts are clamped through clamping bolts; the piston rod and the hanging head are in threaded connection with the connecting block from the left side and the right side respectively.
By adopting the technical scheme, a more reliable and convenient connection mode between the piston rod and the hanging head is realized.
Furthermore, the connecting threads among the connecting block, the piston rod and the hanging head are trapezoidal threads;
through adopting above-mentioned technical scheme, trapezoidal thread can satisfy the requirement of higher intensity and rigidity, is applicable to the transmission of mechanism.
Furthermore, the connecting block and the piston rod of the utility model are connected by right-handed screw threads, and the connecting block and the hanging head are connected by left-handed screw threads;
through adopting above-mentioned technical scheme, effectively prevent that the screw thread from becoming flexible.
Furthermore, the split nut structure of the utility model is two parts of symmetrical split, and is fixed after adjusting the gap through the clamping bolt, the first fastening nut and the second fastening nut;
through adopting above-mentioned technical scheme, can adjust the clearance, can not sting in addition, convenient dismantlement, only need when dismantling piston rod and hanging the head loosen the clamp bolt on first fastening nut, connecting block, the second fastening nut can, convenient and fast.
The beneficial effects of the utility model are that the utility model discloses a connecting block cooperation fastening nut and the clamping bolt of a subdivision nut structure realize the piston rod and hang being connected between the head, compare the direct threaded connection among the conventional art, and this kind of connection structure is more reliable, also convenient the dismantlement simultaneously, is difficult to take place to sting and dies, and overall structure is simple moreover, convenient processing, and the processing cost is low.

Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic drawings, which illustrate the basic structure of the present invention in a schematic manner, and thus show only the components related to the present invention.
Fig. 1 to fig. 3 show an embodiment of a connection structure between a piston rod and a suspension head according to the present invention, which includes a piston rod 1, a connection block 2 and a suspension head 3, wherein the piston rod 1 and the suspension head 3 are connected through the connection block 2; the left end and the right end of the connecting block 2 are respectively provided with a first fastening nut 4 and a second fastening nut 5, the connecting block 2, the first fastening nut 4 and the second fastening nut 5 are all of symmetrical split nut structures, and the joints are clamped through clamping bolts 6; the piston rod 1 and the hanging head 3 are in threaded connection with the connecting block 2 from the left side and the right side respectively.
Wherein, the connecting thread between the connecting block 2 and the piston rod 1 and the hanging head 3 is a trapezoidal thread; the connecting block 2 is in right-hand threaded connection with the piston rod 1, and the connecting block 2 is in left-hand threaded connection with the hanging head 3;
the working principle is as follows: adjusting gaps of a connecting block 2, a first fastening nut 4 and a second fastening nut 5 of a symmetrical split nut structure through a clamping bolt 6 and the first fastening nut 4 and the second fastening nut 5, and then fixing; the piston rod 1 is connected with the left side of the connecting block 2 through right-handed threads, and the hanging head 3 is connected with the right side of the connecting block 2 through left-handed threads.
Trapezoidal thread is applicable to the structure transmission, and overall structure can adjust the clearance, can not sting moreover, and convenient the dismantlement only needs when dismantling piston rod 1 and hanging head 3 with the clamp bolt 6 on first fastening nut 4, connecting block 2, the second fastening nut 5 loosen can, convenient and fast.
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.
