An oil cylinder comprises the stop pipe. In this way, the utility model discloses locking pipe for hydro-cylinder and hydro-cylinder thereof can be convenient for equip, reduce the processingamount, and processing is simple, reduction in production cost.
Description
Technical Field
The utility model relates to a hydro-cylinder field especially relates to a locking pipe for hydro-cylinder and hydro-cylinder thereof.
Background
Some hydro-cylinders inside need to arrange very long stopper pipe, the effect of stopper pipe: on the basis of ensuring the installation distance required by a customer and the exposed piston rod, if the stroke is longer than the stroke required by the customer, a stop pipe is required to share a part of the stroke, so that the stroke, the exposed part and the installation distance required by the customer are ensured. In actual production, when the oil cylinder is assembled, the long stop tube is generally difficult to assemble on the piston rod, particularly the piston rod with a small rod diameter, the inner hole of the stop tube is difficult to process, the coaxiality cannot be well guaranteed, and the assembly is difficult.
Disclosure of Invention
The utility model discloses the main technical problem who solves provides a locking pipe for hydro-cylinder and hydro-cylinder thereof, can be convenient for equip, reduce the processingquantity, processing is simple, reduction in production cost.
In order to solve the technical problem, the utility model discloses a technical scheme be: the utility model provides a locking pipe for hydro-cylinder, establishes the locking pipe on the piston rod including the cover, both ends fixedly connected with dog about the locking pipe, the dog has the protruding structure that stretches out towards the axial direction of locking pipe, protruding structure stretches out in the hole of locking pipe to protruding structure is connected with the cooperation of piston rod, makes the clearance have between the hole of locking pipe and the outer wall of piston rod.
In a preferred embodiment of the present invention, the stoppers are fixedly connected to the left and right ends of the stopper tube by welding.
In a preferred embodiment of the present invention, the cross section of the protruding structure is trapezoidal, and the inner section of the protruding structure slightly protrudes from the inner hole of the stopping tube.
For solving the technical problem, the utility model discloses a another technical scheme is: the oil cylinder comprises the stop pipe, the stop pipe is sleeved on a piston rod of the oil cylinder, and an inner hole of the stop pipe is arranged in a clearance with the outer wall of the piston rod.
The utility model has the advantages that: the utility model discloses locking pipe for hydro-cylinder and hydro-cylinder thereof can be convenient for equip, reduce the work load, and processing is simple, reduction in production cost.
Drawings
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the description of the embodiments are briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained without inventive work, wherein:
FIG. 1 is a schematic view of a preferred embodiment of a stopper tube of the present invention;
FIG. 2 is a schematic view showing a structure of a cylinder having the stopper tube;
the parts in the drawings are numbered as follows: 1. stop tube, 2, dog, 3, protruding structure, 4, hydro-cylinder, 5, piston rod.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1 and 2, a stop tube for an oil cylinder includes a stop tube 1 sleeved on a piston rod 5, the left and right ends of the stop tube 1 are fixedly connected with stoppers 2, each stopper 2 has a protrusion structure 3 extending in the axial direction of the stop tube 1, the protrusion structure 3 extends out of an inner hole of the stop tube 1, and the protrusion structure 3 is connected with the piston rod 5 in a matching manner, so that a gap is formed between the inner hole of the stop tube 3 and the outer wall of the piston rod 5.
The stoppers 2 are fixedly connected to the left and right ends of the stopper tube 1 by welding.
In addition, the cross section of the convex structure 3 is trapezoidal, and the inner section of the convex structure 3 slightly extends out of the inner hole of the stop pipe 1.
The structure of the stop pipe is optimized, and for the oil cylinder with the smaller diameter of the piston rod 5 and the longer stop pipe 1, the structure is adopted, so that firstly, the pipe body part of the stop pipe 1 does not need to be processed, the processing difficulty is avoided, and the processing amount is reduced; secondly, the inner hole of the tube body is far larger than the rod diameter of the piston rod 5, so that the problem of difficult assembly is avoided; thirdly, the stop blocks 2 welded at two ends of the stop tube 1 are finish-machined and matched with the piston rod 5, the machining amount is small, the machining is simple, and a guide ring or an O-shaped ring can be added at the positioning end to ensure the coaxiality.
An oil cylinder comprises the stop pipe 1, wherein the stop pipe 1 is sleeved on a piston rod 5 of an oil cylinder 4, and an inner hole of the stop pipe 1 is arranged in a clearance with the outer wall of the piston rod 5.
Be different from prior art, the utility model discloses locking pipe for hydro-cylinder and hydro-cylinder thereof can be convenient for equip, reduce the processingamount, and processing is simple, reduction in production cost.
The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all of which utilize the equivalent structure or equivalent flow transformation made by the content of the specification of the present invention, or directly or indirectly applied to other related technical fields, all included in the same way in the patent protection scope of the present invention.
