[0002] At present, in the expansion equipment, the T-shaped key is a part that slides and connects the cone and the wedge in the diameter-expanding equipment. In the prior art, the T-shaped key is a common T-shaped structure, which only serves as a connection between the cone and the wedge. The role of the parts, no lubrication function, poor lubrication effect, easy to have garbage and other impurities stuck on the contact surface during the assembly process, affecting the connection between the cone and the wedge, shortening the service life of the T-shaped key, and high cost

Embodiment Construction
[0019] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.
[0020] like figure 1 , figure 2 , image 3 and Figure 4 As shown, the T-shaped key structure of the present embodiment includes a T-shaped key body 3, and the T-shaped key body 3 has an elongated strip structure, and a plurality of bolt holes 2 are spaced apart on the T-shaped key body 3, and the T-shaped key body 3 A lubricating process groove 5 is provided at the boss; lubricating grooves 4 are respectively opened on both sides of the protruding part on the upper part of the T-shaped key body 3, and the lubricating groove 4 extends to the lubricating process groove 5.
[0021] A process hole 1 is arranged at one end of the T-shaped key body 3 .
[0022] The lubricating process groove 5 forms an arc structure.
[0023] T-shaped key body 3 adopts copper material.
[0024] The T-shaped key body 3 is made of beryllium copper made of ...

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 [0001] The invention relates to the technical field of diameter expansion equipment, in particular to a T-shaped key structure used for installing a diameter expansion cone and a wedge connection work. Background technique [0002] At present, in the expansion equipment, the T-shaped key is a part that slides and connects the cone and the wedge in the diameter-expanding equipment. In the prior art, the T-shaped key is a common T-shaped structure, which only serves as a connection between the cone and the wedge. The function of the parts has no lubrication function, and the lubrication effect is poor. During the assembly process, impurities such as garbage are likely to be stuck on the contact surface, which affects the connection between the cone and the wedge, shortens the service life of the T-shaped key, and is costly. Contents of the invention [0003] Aiming at the shortcomings in the above-mentioned existing production technology, the applicant provid...
