Abstract
The invention relates to a T-shaped key structure, which comprises a T-shaped key body in a long stripe structure, wherein a plurality of screw bolt holes are formed in the T-shaped key body at intervals, a lubricating process groove is formed at a lug boss part of the T-shaped body, and lubricating grooves are respectively formed at the two sides of a projected part positioned at the upper part of the T-shaped key body, and extend to the lubricating process groove. The T-shaped key structure has the advantages that the structure is reasonable, the manufacturing is convenient, the lubricating grooves are respectively formed at the two sides of the projected part of the upper part of the T-shaped key body, a better lubricating effect is realized, the defect that garbage can be clamped on a contact surface because the lubricating effect is poor in the prior art is overcome, the connection reliability is improved, the service life of the T-shaped key is prolonged, and the cost is reduced.
Description
Technical field
The present invention relates to the hole enlargement equipment technical field, especially a kind of for the T-shaped bond structure of hole enlargement cone and voussoir connection work is installed.
Background technique
At present, in hole enlargement equipment, T-shaped key is the parts that in hole enlargement equipment, cone and voussoir inclined-plane are slidably connected, in prior art, T-shaped key is general T type structure, only play the effect of cone and voussoir connected element, unlubricated function, lubrication effect is poor, in assembly process, easily there are the impurity such as rubbish to be stuck on surface of contact, affect the work that is connected of cone and voussoir, shorten the working life of T-shaped key, cost is high.
Summary of the invention
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of T-shaped bond structure rational in infrastructure, thereby makes its high lubricating effect, improves the working life of T-shaped key, and functional reliability is good, and cost is low.
The technical solution adopted in the present invention is as follows:
A kind of T-shaped bond structure, comprise T-shaped key body, described T-shaped key body growth strip structure, and on described T-shaped key body, interval has a plurality of bolts hole, and the boss place of described T-shaped key body is provided with the lubricating process groove; The both sides that are positioned at T-shaped key body top projection have lubrication groove, and described lubrication groove extends to the lubricating process groove.
As further improvement in the technical proposal:
Be positioned at T-shaped key body one end and have auxiliary hole;
Described lubricated lubricating process groove becomes arc structure;
Described T-shaped key body adopts copper product;
Described T-shaped key body adopts the beryllium copper of copper alloy material.
Beneficial effect of the present invention is as follows:
The present invention is rational in infrastructure, easy to make, by distinguish the processing and lubrication groove in projection both sides, T-shaped key body top, reach lubrication effect preferably, avoid in prior art lubrication effect poor and cause having rubbish to be stuck in the defect on contact surface, improved connection reliability, extended the working life of T-shaped key, reduced costs.
The present invention adopts the beryllium copper material, has high wear resistance, good lubrication, long service life, and cost is low.

The plan view that Fig. 2 is Fig. 1.
The left view that Fig. 3 is Fig. 1.
The partial enlarged drawing that Fig. 4 is A section in Fig. 3.
Wherein: 1, auxiliary hole; 2, bolt hole; 3, T-shaped key body; 4, lubrication groove; 5, lubricating process groove.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the T-shaped bond structure of the present embodiment, comprise T-shaped key body 3, T-shaped key body 3 growth strip structures, and on T-shaped key body 3, interval has a plurality of bolts hole 2, and the boss place of T-shaped key body 3 is provided with lubricating process groove 5; The both sides that are positioned at T-shaped key body 3 top projections have lubrication groove 4, and lubrication groove 4 extends to lubricating process groove 5.
Be positioned at T-shaped key body 3 one ends and have auxiliary hole 1.
Lubricated 5 one-tenth arc structures of lubricating process groove.
T-shaped key body 3 adopts copper product.
T-shaped key body 3 adopts the beryllium copper of copper alloy material.Itself have good lubricating and wear-resisting, and oil absorption is good, heat conduction amount is fast, high temperature resistant, and various intensity also meets T-shaped key job requirement.
Adopt the T-shaped key of tin bronze, 3000～5000 steel pipes of actual use have been scrapped with regard to wearing and tearing later, and adopt the actual usage quantity of T-shaped key of beryllium copper to reach 20000～50000 steel pipes, long service life.
The present invention adopts beryllium copper, reduces the characteristic that cone and T-shaped key directly contact the friction of formation, by being strict with T-shaped key self size, it is connected to the gap value on the surperficial and voussoir inclined-plane of assurance cone with cone with voussoir.In addition, on T-shaped key body 3, added lubrication groove 4, reached lubrication effect, avoided in prior art having the impurity such as rubbish and be stuck in contact surface, improved connection reliability, increased the service life.
Above description is explanation of the invention, is not that limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification to the restriction of invention.
