Abstract
The utility model discloses a novel cylinder head connecting component structure for a hydraulic cylinder, belonging to the field of a hydraulic cylinder. The novel cylinder head connecting component structure comprises a cylinder barrel, a gland, a guide sleeve, a clamping key and a group of inner hexagon screws, wherein a clamping key slot is machined at an internal hole of the cylinder barrel; the external edge of the clamping key and two end surfaces of the upper part of the clamping key are embedded in the clamping key slot; two end surfaces of the lower part of the clamping key are matched with the guide sleeve and a gland positioning slot respectively; the guide sleeve and the gland are connected with each other by the group of inner hexagon screws; after the inner hexagon screws are screwed down, the guide sleeve and a positioning hole in the middle part of the gland are fastened in the guide sleeve and the positioning slot of the gland by the clamping key. The novel cylinder head connecting component structure has the benefits of breaking through a traditional threaded connection structure of an original cylinder barrel and an original guide sleeve, and solving the difficult problems of the traditional threaded connection structure such as inconvenience of assembly and disassembly, easily burning of threads, requirement on the machining type of turning for large-specification nonstandard threads, low machining efficiency, and inconvenience for large-scale batch production. For the novel cylinder head connecting component structure, the quality level of products is improved, the machining cost of the products is reduced, and the structure is compact and novel, the machining efficiency is high, and the assembly and disassembly are convenient.
Description
Technical field
The utility model relates to a kind of oil hydraulic cylinder, specifically be a kind of oil hydraulic cylinder with novel cylinder head connection part structure, be applicable to that mainly kiloton and the supporting supporting leg class of above tonnage crawler-type crane oil hydraulic cylinder guide sleeve thereof connect with cylinder barrel.
Background technique
At present, conventional threads formula linkage structure is all adopted in kiloton and the supporting supporting leg class of above tonnage crawler-type crane oil hydraulic cylinder cylinder head thereof connection (guide sleeve is connected with cylinder barrel).The shortcoming of conventional threads formula linkage structure is: loading and unloading are inconvenient, screw thread is easily burnt to death, and big specification and nonstandard screw thread need be joined car, and work efficiency is low, are unfavorable for extensive, property production in batches.
Summary of the invention
The utility model provides a kind of oil hydraulic cylinder with novel cylinder head connection part structure, and purpose is in order to overcome the above-mentioned deficiency of conventional threads formula linkage structure.
The utility model is to realize with following technological scheme: a kind of oil hydraulic cylinder is with novel cylinder head connection part structure, comprise cylinder barrel, card key, guide sleeve and gland, described cylinder barrel endoporus is processed with circlip groove, card key outer rim and both upper ends thereof face and embeds in the circlip groove, and the bottom both ends of the surface of card key embed in the locating slot of guide sleeve, gland; It is fastening that guide sleeve and gland are connected with one group of socket head screw, and the card key with guide sleeve and gland interfix after socket head screw is tightened is fastened in the locating slot of guide sleeve and gland.。
Owing to adopted said structure, break through original cylinder barrel and the guide sleeve linkage structure with the conventional threads formula, solved that the loading and unloading of conventional threads formula linkage structure are inconvenient, screw thread is easily burnt to death, big specification and nonstandard screw thread need be joined car, work efficiency is low, is unfavorable for a difficult problem extensive, the production of batch property.Improved simultaneously product quality level, reduced the processing cost of product.
The beneficial effects of the utility model are: compact structure, novelty, and the work efficiency height, easy to loading and unloading.
Description of drawings
Below in conjunction with accompanying drawing and example the utility model is further specified.
Fig. 1 is the utility model cylinder head structural representation.
Among the figure: 1, one group of socket head screw, 2, gland, 3, the card key, 4, guide sleeve, 5, cylinder barrel.
Embodiment
As shown in Figure 1, oil hydraulic cylinder comprises cylinder barrel 5, card key 3, guide sleeve 4 and gland 2 with novel cylinder head linkage structure; Cylinder barrel 5 endoporus be processed with circlip groove, card key 3 outer rims and on both ends of the surface embed in the circlip groove, 3 times both ends of the surface of card key embed in guide sleeve 4, gland 2 locating slots; One group of socket head screw 1 of guide sleeve 4 and gland 2 usefulness is connected, and after socket head screw 1 is tightened the card key 3 of guide sleeve 4 with gland 2 interfixes is fastened in the locating slot of guide sleeve 4 and gland 2.
