The utility model is further set to: described the first cavity wall thickness is greater than 0.5mm.
By adopting technique scheme, strengthen the first cavity wall intensity, strengthen the stability of frock.
The utility model is further set to: described the first kerf width equals the first cavity diameter, and described the second otch equals the second cavity diameter.
By adopting technique scheme, be conducive at utmost ensure the contact-making surface of frock and brake steady pin.
The utility model is further set to: described the first cavity and the second cavity faying face are provided with chamfering.
By adopting technique scheme, prevent that the first cavity and the second cavity faying face from producing stress and concentrating in the process press-fiting, cause destroying frock.

Detailed description of the invention
Referring to figs. 1 through Fig. 5, a kind of pad axle of the utility model frock embodiment is described further.
In a kind of pad axle frock depression bar 1, be provided with cavity, cavity is cylindrical cavity, cavity axial direction is consistent with depression bar axial direction, cavity comprises the first cavity 3 and the second cavity 4, the first cavity 3 diameters are less than the second cavity 4 diameters, the first cavity 3 communicates with the second cavity 4, the first cavity 3 is through the end face of depression bar 1, the sidewall of depression bar 1 is provided with otch, otch is through the sidewall of depression bar, otch comprises the first otch 5 and the second otch 6, the first otch 5 is positioned on the sidewall of the first cavity 3, the second otch 6 is positioned on the sidewall of the second cavity 4, the first otch 5 width are less than the second otch 6 width, the first otch 5 communicates with the second otch 6, so just can avoid hydraulic cylinder to directly act on the first bearing pin cap, make stress point transfer to the second bearing pin cap, effectively solve and press-fited the difference due to stressed position in process and make the first bearing pin body generation deformation.
Wherein depression bar 1 is cylinder, and cylindrical cavity is concentric with depression bar 1, and the first cavity 3 walls are provided with quench hardened case, in the process press-fiting, make the strength-enhanced of the first cavity wall, promotes the durability degree of depression bar.
The upper end sidewall of depression bar 1 is provided with decorative pattern, and decorative pattern is latticed decorative pattern, in the process press-fiting, holds depression bar upper end, and being provided with decorative pattern can increase the frictional force between depression bar and palm, makes frock be difficult for skidding off hand.
The first cavity 3 wall thickness are greater than 0.5mm, the first otch 5 width equal the first cavity diameter, the second otch 6 equals the second cavity 4 diameters, making can be more smooth in the process press-fiting, the first cavity 3 and the second cavity 4 faying faces are provided with chamfering 9, thereby prevent that the first cavity 3 and the second cavity 4 faying faces from producing stress and concentrating in the process press-fiting, cause destroying frock.
The fixed pin shaft 8 that wherein brakes comprises the first bearing pin cap 81, the second bearing pin cap 82, the first bearing pin body 83, the second bearing pin body 84, the first bearing pin cap 81, the second bearing pin cap 82, the first bearing pin body 83 and the second bearing pin body 84 are all cylindrical structure, wherein the first bearing pin cap 81 length are less than the first bearing pin body 83 length, the second bearing pin cap 82 length are less than the first bearing pin cap 81 length, the first bearing pin cap 81 is fixedly connected with the second bearing pin cap 82 upper surfaces by the first bearing pin body 83, the second bearing pin body 84 is fixedly connected with the second bearing pin cap 82 lower surfaces, the first bearing pin body and the first cavity are suitable.
