Abstract

The welding splash protection structure of the hydraulic cylinder comprises a cylinder barrel, a cylinder bottom component, a screw and an oil pipe which are matched with each other; wherein, be equipped with the screw thread on the position of oil port hole on the cylinder, plug up the oil port hole in the screw thread on the screw in cylinder when welding cylinder bottom subassembly, take out welding oil pipe with the screw after having welded, the utility model discloses adopting neotype welding protective structure to design, the welding splashes the problem that gets into the hydro-cylinder.

Description

Welding splash protection structure of hydraulic oil cylinder

The technical field is as follows:

the utility model belongs to the technical field of the hydro-cylinder processing, a hydraulic cylinder welding protective structure that splashes that is suitable for among hydraulic cylinder bottom of a jar subassembly and the cylinder body welding process that contains oil pipe is related to.

Background art:

at present, in aerial work platforms and environmental engineering products, due to the continuous upgrading of the safety requirements of the products, the requirements on a hydraulic system are higher and higher. For hydraulic oil cylinder products, the working mechanism of the hydraulic oil cylinder product requires cleanliness reaching the NAS1638 standard 8 level due to the requirement of working property. This requires that the operating mechanism not allow weld spatter to enter the interior of the cylinder.

In the prior art, the welding process of the oil cylinder bottom assembly is not good in protection, welding slag often splashes into the oil cylinder, the splashing is not well cleared when the assembly is cleaned, and once the splashing is in the oil cylinder, the hydraulic oil cylinder is pulled to cause inner leakage or a valve core of a hydraulic system is clamped to cause faults such as action failure.

The invention content is as follows:

the utility model aims to overcome above-mentioned shortcoming, provide a hydraulic cylinder welding protective structure that splashes, it can effectively prevent welding process to splash the welding slag and get into the hydraulic fluid port downtheholely.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the welding splash protection structure of the hydraulic cylinder comprises a cylinder barrel, a cylinder bottom component, a screw and an oil pipe which are matched with each other; the screw is screwed into the upper thread of the cylinder barrel to block the oil hole when the cylinder bottom assembly is welded, and the welded oil pipe is taken out of the screw after welding.

Adopt above-mentioned technical scheme, the utility model discloses adopting neotype welding protective structure design, the welding splashes the problem that gets into the hydro-cylinder.

Description of the drawings:

the accompanying drawings, which are described herein, serve to provide a further understanding of the invention and constitute a part of this specification, and the exemplary embodiments and descriptions thereof are provided for explaining the invention without unduly limiting it. In the drawings:

FIG. 1 is a schematic view of the thread processing of the oil port hole of the cylinder barrel of the present invention;

FIG. 2 is a schematic view of the cylinder barrel of the present invention screwed in the screw and welded with the cylinder bottom assembly;

fig. 3 is the utility model discloses take out screw welding oil pipe schematic diagram.

The specific implementation mode is as follows:

in order to make the technical problem, technical solution and advantageous effects to be solved by the present invention clearer and more obvious, the following description of the present invention with reference to the accompanying drawings and embodiments is provided for further details. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

As shown in fig. 1-3, in order to implement the embodiment of the present invention, the welding splash protection structure for the hydraulic cylinder comprises a cylinder barrel 1, a cylinder bottom component 2, a screw 3 and an oil pipe 4 which are mutually matched; wherein, be equipped with the screw thread on the position of oil port hole 11 on cylinder 1, screw 3 is screwed in the screw thread on cylinder 1 and is blockked up oil port hole 11 when welding cylinder bottom subassembly 2, takes out welding oil pipe 4 with screw 3 after the welding.

The utility model discloses structure manufacturing procedure: firstly, processing threads in an oil port hole of a cylinder barrel 1; secondly, screwing in the screw 3; thirdly, welding the cylinder bottom assembly 2; fourthly, taking out the screw 3; and fifthly, welding the oil pipe 4.

The utility model is suitable for an use when new product and batch production in the pneumatic cylinder trade, be a hydraulic fluid port welding structure of preventing splashing, adopting neotype welding protective structure design, the welding splashes the problem that gets into the hydro-cylinder.

While the foregoing description shows and describes the preferred embodiments of the present invention, it is to be understood that the invention is not limited to the forms disclosed herein, but is not intended to be exhaustive or to exclude other embodiments and may be used in various other combinations, modifications, and environments and is capable of changes within the scope of the inventive concept as expressed herein, commensurate with the above teachings, or the skill or knowledge of the relevant art. But that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the invention, which is to be limited only by the claims appended hereto.

Claims

1. Hydraulic cylinder welding protective structure that splashes, its characterized in that: the device comprises a cylinder barrel, a cylinder bottom component, a screw and an oil pipe which are matched with each other; the screw is screwed into the upper thread of the cylinder barrel to block the oil hole when the cylinder bottom assembly is welded, and the welded oil pipe is taken out of the screw after welding.
