Abstract
The utility model discloses a high pressure oil cylinder, and relates to the technical field of production of high pressure oil cylinders. A rear earring consists of a ring body and a plug which are connected; a cylinder body consists of a large inner cavity section and a small inner cavity section which are integrated; the plug of the rear earring is in threaded connection with the free end of the large inner cavity section of the cylinder body; a plunger consists of a large external diameter section and a small external diameter section which are integrated; the large external diameter section of the plunger is matched with the large inner cavity section of the cylinder body; the small external diameter section of the plunger is matched with the small inner cavity section of the cylinder body; and an inner screw hole is formed in the center of the free end of the small external diameter section of the plunger. The plug of the rear earring replaces the sealed end of the cylinder body in the conventional product, so that the cylinder body is convenient to process, and the production raw material cost of the cylinder body is saved; and the cylinder body and a front cylinder cover are integrated, so that material cost is saved, and the problem that the requirement on the connecting strength of the cylinder body and the cylinder cover is high is solved.
Description
Technical field
The utility model relates to a kind of production technical field of high-voltage oil cylinder.
Background technique
The mode of structure of traditional oil cylinder is adopted in high-voltage oil cylinder design at present mostly, and processing technology also adopts existing mature technology mostly.Existing high-voltage oil cylinder great majority all are to adopt cylinder body and cylinder cap separated type, and cylinder cap and cylinder body are used the bolt ways of connecting.This structure cylinder cap boundary dimension is big, cost is high, and cylinder body and cylinder cap join strength require high.The inner chamber of cylinder block of high-voltage oil cylinder adopts the honing processing technology mostly, and cylinder surface hardness is low, and is easy to wear, and working life is short.Plating hard chromium on surface was handled after the oil cylinder plunger often adopted quenching with Subsequent tempering.Chromium coating is easy to wear behind the frequent movement, takes off chromium, and plunger surface is prone to plucking, leakage of oil.
Summary of the invention
The utility model purpose is in order to overcome the defective of existing technology, to propose the better high-voltage oil cylinder of a kind of product technology performance.
The utility model comprises cylinder body, plunger and back earrings; It is characterized in that said back earrings is made up of interconnective ring body and plug; Said cylinder body is made up of big inner chamber section and little inner chamber section that the phase interconnect is provided with, and the plug of said back earrings is threaded in the free end of the big inner chamber section of said cylinder body; Said plunger is made up of big outer diameter section and small outer diameter section that the phase interconnect is provided with, and the big inner chamber section of the big outer diameter section of said plunger and said cylinder body cooperatively interacts, and the little inner chamber section of the small outer diameter section of said plunger and said cylinder body cooperatively interacts; Free end center at the small outer diameter section of said plunger is provided with inner bolt hole.
The utility model has substituted the sealed end of cylinder body in the existing product with the plug of back earrings, makes the processing of cylinder body more convenient, also saves cylinder body raw materials cost.Cylinder body and front end housing design is as a whole, saved cost of material, overcome the high problem of requirement of strength that cylinder body is connected with cylinder cap simultaneously.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Embodiment
As shown in Figure 1, the utility model is mainly formed by drawing together cylinder body 1, plunger 2 and back earrings 3.
Cylinder body 1 is made up of big inner chamber section 1-1 and little inner chamber 1-2 section that the phase interconnect is provided with, and the free end of big inner chamber section 1-1 is provided with internal thread 1-3.
The big inner chamber section 1-1 of the big outer diameter section 2-1 of plunger 2 and cylinder body 1 cooperatively interacts, and the little inner chamber section 1-2 of the small outer diameter section 2-2 of plunger 2 and cylinder body 1 cooperatively interacts.
The plug 3-2 of back earrings 3 is provided with the outside thread that matches with the big free-ended internal thread 1-3 of inner chamber section 1-1, is threaded in the free end of the big inner chamber section 1-1 of cylinder body 1 through outside thread.
