Abstract
The utility model relates to an oil cylinder, and particularly relates to an overlap removing oil cylinder for a movable type flash welding machine. The overlap removing oil cylinder includes an oil cylinder body and a piston rod extending out of the oil cylinder body, and a detachable connecting part is arranged at the end of the exposed end of the piston rod. After the overlap removing oil cylinder is used, the detachable connecting part can be replaced as needed, so that the service life of the overlap removing oil cylinder is greatly prolonged.
Description
Technical field
The utility model relates to a kind of oil cylinder, and especially a kind of portable flash welder is with pushing away knurl oil cylinder.
Background technique
In the on-the-spot steel rail laying of the circuits such as railway, subway, need to use mobile steel rail flash welder, last step of mobile steel rail flash welder automatic welding pushes away celectome excision overlap for pushing away the drive of knurl oil cylinder.Existing push away knurl oil cylinder piston rod generally by round steel wire, be processed into; Add and first will carry out straightening, blanking, turning, quenching, cylindrical grinding man-hour, then electroplate, polishing; But in use there is following deficiency: the one, because the piston rod poor rigidity of processing with round steel wire adds man-hour yielding under cutting force effect, whole process for long piston rod disqualification rate is high, work efficiency is low; The 2nd, the diameter exposing due to piston rod is large, and oil cylinder internal piston shank diameter is little, pushes away knurl oil cylinder assembling difficulty large, and need to use special tooling; The 3rd, push away knurl cylinder piston rod and push away the impact that celectome connection part is subject to frictional force, extruding force, crooked moment of torsion, easy to wear, easily extrusion, maintain and replace cost is high.
Model utility content
The purpose of this utility model is: the problem existing for above-mentioned prior art, by architecture advances, propose to be a kind ofly convenient to process, can increase the service life, be convenient to maintain and replace, be applicable to that overlap excises push away knurl oil cylinder.
In order to reach above object, the knurl oil cylinder that pushes away of the present utility model, comprises cylinder body and the piston rod from stretching out in cylinder body, and the end of piston rod exposed junction is fixed with detachable connection part.
Preferred version of the present utility model is:
Further, detachable connection part comprises attachment post, and the outer end of piston rod has axially extended thread head, and one end of attachment post adjacent piston bar is screwed and is connected with the thread head of piston rod by axial screw thread hole.
Further, one end of attachment post adjacent piston bar also has the counterbore that holds piston rod end.
Further, detachable connection part comprises attachment post and connecting head, and the outer end of piston rod and connecting head all has axially extended thread head, and the two ends of attachment post have respectively the interior threaded hole screwing with piston rod and connecting head.
Further, between connecting head and attachment post, be also fixed with profile of tooth lock washer.
Further, on the screw thread hole wall of attachment post, be embedded with Cock screw and positioning ball, the end sidewalls that piston rod screws in attachment post is provided with first ring connected in star, when piston rod and attachment post screw while setting station, Cock screw compresses positioning ball, and positioning ball is just embedded in first ring connected in star, positioning ball compressing piston rod, prevent the thread looseness of piston rod and attachment post, there is certain coupling mechanism force.
The utility model beneficial effect is: the utility model can meet service condition, can reduce production costs again, and easy to process, polishing effect good; After use, can be by take the circumstances into consideration changing the section of removably connecting, thus greatly extend the life-span that pushes away knurl oil cylinder.
