Description

The hose coupling of hydraulic system

Technical field

The utility model relates to hose coupling field, in particular to a kind of hose coupling of hydraulic system.

Background technique

Current hydraulic system hose coupling is generally had the tube filler group of Hexagonal jacket seat by hex nut, sleeve and middle part At, it is complicated at the vehicle cutting process of, Hexagonal jacket by cutting technique vehicle since Hexagonal jacket seat is structure as a whole with tube filler, than Compared with waste cutter, and the process time is longer, and since Hexagonal jacket and tube filler are structure as a whole, and hex nut needs pass through button Pressure technique could be fixed with the tail portion of tube filler, and sleeve is also required to that fixation could be withheld with tube filler by once withholding, complex process, Higher cost.

Summary of the invention

Goal of the invention: aiming at the problems existing in the prior art, the hose that the utility model provides a kind of hydraulic system connects The assembling of hose coupling each section need to only can be realized in head by once withholding, and save production cost.

Technical solution: the utility model provides a kind of hose coupling of hydraulic system, including nut, receiver, sleeve And tube filler, the nut, the receiver and the sleeve are successively covered from tail portion to head in the outside of the tube filler, described Nut limits at the limit convex edge of the tube filler tail portion, and receiver one end adjacent with the sleeve has cooperation recessed Slot, sleeve one end adjacent with the receiver have cooperation convex edge, and the cooperation convex edge covers outside the mating groove The other end of side wall, the sleeve is open end, and the head of the tube filler is located in the sleeve.

Further, the middle part lateral wall of the tube filler have the first annular knurl distributed along its axial direction, the receiver with Pass through the first annular knurl defined position between the tube filler.The setting of first annular knurl is so that position between receiver and tube filler Stablize, convenient for the smooth realization of subsequent withholding of technology.

Further, first also withholds screw thread on the head lateral wall of the tube filler；In the inside of the sleeve Also have second to withhold screw thread on wall.First withhold screw thread and second withhold screw thread setting be to increase outside the head of tube filler Frictional force between side wall and hose inner sidewall, the inner sidewall of sleeve and the lateral wall of hose, in this way after withholding of technology, The more consolidation that can just withhold between tube filler, hose and sleeve three guarantees sealing effect and stability between three.

The utility model additionally provides a kind of production method of the hose coupling of above-mentioned hydraulic system, comprising the following steps: S1: prepare the tube filler of the tail portion with limit convex edge, the nut, one end have mating groove the receiver and One end has the sleeve of cooperation convex edge；S2: the nut is covered on the outside on wall from the head of the tube filler, and by institute Nut limit is stated at the limit convex edge of the tube filler tail portion；S3: the receiver is covered outside it from the head of the tube filler On side wall, and the receiver is placed in the middle part of the tube filler；S4: the sleeve is covered outside it from the head of the tube filler On side wall, and the cooperation convex edge of the sleeve is covered on the mating groove lateral wall of the receiver；S5: by the receiver Overlapping with the sleeve in the mating groove with the cooperation convex edge, which is buckled, to be forced together.

Further, in the S1, the middle part lateral wall of the tube filler return the car out it is distributed along its axial direction first rolling Flower；In the S3, by the receiver from first annular knurl that the head of the tube filler covers on lateral wall in the middle, Therebetween pass through the first annular knurl defined position.

Further, it in the S1, also gets on the bus out in the head lateral wall of the tube filler and first withholds screw thread.

Further, in the S1, second is also produced on the inner sidewall of the sleeve and withholds screw thread.

The utility model has the advantages that in the utility model, nut in the hose coupling of hydraulic system directly from the head of tube filler cover to Tail portion limit convex is at, without passing through withholding of technology；Pass through mating groove between receiver and sleeve and cooperates the overlapping of convex edge And connect, then both it may be implemented by once withholding by nut, receiver, sleeve and tube filler four in the part of the two overlapping Person, which assembles, to complete, and production method is very easy；Since receiver and tube filler are independent from each other structure, receiver can directly lead to It crosses cold heading technique to be prepared, tube filler is also easier to realize by vehicle cutting process, saves cutter, saves cost.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the hose coupling of hydraulic system；

Fig. 2 is hose coupling and the hose buckling of hydraulic system to the structural schematic diagram after together.

Specific embodiment

The utility model is described in detail with reference to the accompanying drawing.

Present embodiments provide for a kind of hose couplings of hydraulic system, as shown in Figure 1, the connector is mainly excellent by nut 1( Select octagon nut), the preferred Hexagonal jacket seat of receiver 2(), sleeve 3 and tube filler 4 form, 1 set of the nut tail portion in tube filler 4 limits By the limit convex along 401 limits at convex edge 401；2 sets of the receiver middle parts in tube filler 4 are arranged on the middle part lateral wall of tube filler 4 Position is limited by the first annular knurl 402 between the middle part lateral wall of first annular knurl 402 distributed along its axial direction, receiver 2 and tube filler 4 It sets；3 sets of the sleeve heads in tube filler 4, the one end adjacent with sleeve 3 of receiver 2 have mating groove 201, sleeve 3 and receiver 2 adjacent one end have cooperation convex edge 301, cooperate 301 sets of convex edge on 201 lateral wall of mating groove；The head of tube filler 4 is located at In sleeve 3, the one end of sleeve 3 far from receiver 2 is open end, also has first to withhold screw thread on the head lateral wall of tube filler 4 403, have on the inner sidewall of sleeve 3 second to withhold screw thread 302.

The hose coupling of above-mentioned hydraulic system the production method is as follows:

S1: going out tail portion using cutting technique vehicle has first distributed along its axial direction first along 401, middle part with limit convex Annular knurl 402, head have the first tube filler 4 for withholding screw thread 403；Nut 1 is prepared using cold heading technique；Use cold heading technique system Standby one end out has the receiver 2 of mating groove 201；And inner sidewall is prepared using cold heading technique and withholds screw thread with second 302, one end has the sleeve 3 of cooperation convex edge 301；

S2: nut 1 is covered on wall on the outside from the head of tube filler 4, and the limit of nut 1 is arrived to the limit of 4 tail portion of tube filler At convex edge 401；

S3: receiver 2 is set on the first annular knurl 402 in the middle part of 4 lateral wall of tube filler from the head of tube filler 4；

S4: sleeve 3 is covered on the outside on wall from the head of tube filler 4, and by 301 sets of the cooperation convex edge of sleeve 3 in sleeve On 201 lateral wall of mating groove of seat 2；

S5: the overlapping by receiver 2 and sleeve 3 in mating groove 201 and cooperation convex edge 301, which is buckled, to be forced together.

When using the hose coupling, one end of hose 14 to be withheld is inserted between sleeve 3 and tube filler 4 first, i.e., it is soft The inner sidewall of pipe 14 is enclosed in the head lateral wall of tube filler 4, and the inner sidewall of sleeve 3 is wrapped in the lateral wall of hose 14, then leads to The crimping device crossed in embodiment 2 carries out withholding connection to hose 14 and hose coupling, after withholding as shown in Figure 2.

Above embodiment is only to illustrate the technical ideas and features of the present invention, and its object is to allow be familiar with this skill The people of art can understand the content of the utility model and implement accordingly, not limit the protection scope of the present invention.
