Compared with the prior art, when being used in a certain type valve body, the connection deadman has complicated structure, simple manufacture process, convenience in assembly, long service life, and foreseeable greater economical and social value.
Description
Technical field
The utility model relates to the automobile-used overload hydraulic valve body of concreting and connects dead man relevant structural design and applied technical field, provides the automobile-used overload hydraulic valve body of a kind of concreting to connect dead man especially.
Background technique
In the existing technology, the driving lever material pieces is generally gray cast iron (HT200).This kind material pieces intensity is high, wear-resisting, and certain toughness is arranged, and is generally used for making the cylinder block, cylinder head of base, frame, worktable, fuselage, gear case body, valve body and the internal-combustion engine of various machines etc.
In the using process of most hydraulic valve, traditional valve body connects with needs driving lever complex structure, be difficult for assembling, and working life is very short.Therefore, people expect to obtain a kind of technique effect better coagulation soil and build automobile-used overload hydraulic valve body and connect dead man.
Summary of the invention
The purpose of the utility model provides a kind of technique effect better coagulation soil and builds automobile-used overload hydraulic valve body connection dead man.
The automobile-used overload hydraulic valve body of a kind of concreting of the utility model connects dead man, and material is a gray cast iron; It is characterized in that: it specifically is made up of the fixing part 2 of tabular dead man body 1 and tubulose; Wherein, dead man body 1 is fixed on the outer wall of fixing part 2 and the two constitutes an integral body, and dead man body 1 place plane parallel is in the cross-sectional direction of tubulose fixing part 2; Simultaneously, also have attachment hole 3 in following position:
On the tube wall away from dead man body 1 one sides on the fixing part 2; Dead man body 1 is away from the proximal end of fixing part 2.
The automobile-used overload hydraulic valve body of said concreting connects dead man, it is characterized in that: tabular dead man body 1 offers an end external frame of attachment hole 3 for semicircle, and attachment hole 3 apertures on the dead man body 1 are φ 10 ± 0.01mm;
For the aperture tapped hole of φ 10mm away from the attachment hole on the tube wall of dead man body 1 one sides 3 on the fixing part 2.
Further preferred the requirement is: in the fixing part 2 of said tubulose, bore is φ 20 ± 0.01mm, and external diameter of pipe is φ 40mm.
The automobile-used overload hydraulic valve body of said concreting connects in the dead man, and tabular dead man body 1 specifically is to be formed by fixedly connecting the different two-part of thickness, and wherein: the segment thickness away from fixing part 2 is less relatively.
In terms of existing technologies, the utility model in the using process of certain type valve body, its complex structure, preparation process is simple, and is easy to assembly, and long service life.It has foreseeable comparatively huge economy and social value.
Description of drawings:
Fig. 1 connects dead man structural representation plan view for the automobile-used overload hydraulic valve body of concreting;
Fig. 2 is the plan view corresponding with Fig. 1.
Embodiment:
The automobile-used overload hydraulic valve body of a kind of concreting connects dead man (concrete structure please with reference to accompanying drawing 1, shown in 2), and material is a gray cast iron; It specifically is made up of the fixing part 2 of tabular dead man body 1 and tubulose; Wherein, dead man body 1 is fixed on the outer wall of fixing part 2 and the two constitutes an integral body, and dead man body 1 place plane parallel is in the cross-sectional direction of tubulose fixing part 2; Simultaneously, also have attachment hole 3 in following position:
On the tube wall away from dead man body 1 one sides on the fixing part 2; Dead man body 1 is away from the proximal end of fixing part 2.
The automobile-used overload hydraulic valve body of said concreting connects in the dead man, and tabular dead man body 1 offers an end external frame of attachment hole 3 for semicircle, and attachment hole 3 apertures on the dead man body 1 are φ 10 ± 0.01mm;
For the aperture tapped hole of φ 10mm away from the attachment hole on the tube wall of dead man body 1 one sides 3 on the fixing part 2.
In the fixing part 2 of said tubulose, bore is φ 20 ± 0.01mm, and external diameter of pipe is φ 40mm.
The automobile-used overload hydraulic valve body of said concreting connects in the dead man, and tabular dead man body 1 specifically is to be formed by fixedly connecting the different two-part of thickness, and wherein: the segment thickness away from fixing part 2 is less relatively.
The shape of part and dimension analysis: this part is a driving lever; Play interconnect function; The center line in Φ 20 holes of part and the center line in Φ 10 holes will have certain parallelism requirement, and the tolerance that requires parallelism is 0.01, and the center line in Φ 20 holes and the squareness tolerance of bottom surface are 0.02.The machining accuracy in two holes of part is higher, and roughness is 1.6, and the roughness on other planes is 3.2.Two hole deviation of centre distance are 0.02, and the deviation of tapped hole and bottom surface is 0.1, and the deviation of upper and lower surfaces is 0.1, and the deviation in Φ 20, Φ 10 holes is 0.01.
