Detailed Description

The invention will be described in more detail with reference to the following examples, which are given by way of illustration.

As shown with reference to figures 1-3,

a hub bearing end face spline molding riveting cutter comprises a cutter body 1 and splines 2 annularly distributed on the cutter body 1; a plurality of through holes 3 for mounting bolts are arranged on the cutter body 1 around the spline 2, the through holes 3 are arc-shaped, the through holes 3 are uniformly distributed on a concentric track of the spline 2, and the arc shape of the through holes 3 is matched with the concentric track; a step 4 for assembling a bolt is arranged in the through hole 3, and the bolt head of the bolt is assembled with external equipment through the step 4; and a notch 5 for a bolt head of a bolt to pass through is arranged at the end part of the step 4, which is close to the side edge of the circular arc-shaped through hole 3.

Spline 2 on the cutter body 1 is used for the riveting shaping, a plurality of through-hole 3 and evenly distributed with the concentric distribution of spline 2 are on the orbit of concentric circles, have even fixed action, and step 4 in the through-hole 3 in the cooperation, can utilize step 4 and bolt to cooperate, install cutter body 1 on external equipment, because step 4 still has a breach 5, can aim at cutter body 1 with the bolt and peg graft cutter body 1 and bolt cooperation after breach 5 when installing cutter body 1, thereafter rotate cutter body 1, let the tiehead of bolt enter into and carry out the complex state with step 4 and can realize preinstallation, cutter body 1 can not drop this moment, can be with stable the installing on equipment of cutter body 1 along with screwing of bolt. This structure has the assembly fast, from the effect of taking the location, when switching cutter body 1, can the current required cutter body 1 type of quick replacement to the assembled state is reliable and stable.

In order to make the punching and riveting function of the spline 2 stronger, the circular truncated cone 6 is arranged on the cutter body 1, a circular groove is formed in the axis of the circular truncated cone 6, the spline 2 is located on the end face of the circular truncated cone 6, and the recess 12 of the spline 2 is formed by penetrating the circular truncated cone 6 from one side close to the center to the edge. Only one is shown in the figure.

The round platform 6 can increase the strength on the one hand, and on the other hand provides more outstanding position, and it is more convenient to work when can letting punch and rivet. And the sunken 12 of spline 2 forms the state of dark interior shallowly of outside, can let the material of wheel hub bearing terminal surface gather to the axle center when shaping spline 2, strengthens intensity, and then improves load-carrying capacity.

Furthermore, the end of the step 4 away from the notch 5 is provided with a recess 12 for the head of the bolt to be inserted. The position of breach 5 can supply the bolt head embedding of bolt, rotates after the breach 5 that the bolt passed cutter body 1, and it is relative with sunken 12 position to reach the bolt head, then screws the bolt, can let the bolt imbed sunken 12 in, can further improve the stability of assembly after the bolt screws, can avoid the bolt to slide.

More specifically, the step 4 is provided with an inclined surface 7 for guiding the bolt head of the bolt to be attached to the step 4 at a position corresponding to the notch 5. Only one is shown in the figure.

The inclined plane 7 of breach 5 department can cooperate and tie the head, when cutter body 1 rotated, can let inclined plane 7 guide bolt, can not appear tying head and step 4 and appear colliding with and lead to fish tail bolt or lead to the assembly smooth and easy inadequately.

Furthermore, the tool also comprises an adapter 8 which is matched with the tool body 1 for installation, and a cylindrical rotating shaft 9 is concentrically arranged on one surface of the tool body 1, which corresponds to the adapter 8, and the circular track of the through hole 3; and a slot 10 with a shape matched with the shape is arranged on the adaptor 8 corresponding to the position of the rotating shaft 9.

Wherein slot 10 and pivot 9's cooperation, not only can make things convenient for the cooperation of cutter body 1 through-hole 3 and bolt when rotating, can also improve cutter body 1's radial strength, and slot 10 and pivot 9's shape adaptation, after in pivot 9 inserts slot 10, possess radial fixed action, reduce cutter body 1's swing, and help the alignment of breach 5 and bolt, let both can fix fast, because pivot 9 and slot 10's cooperation installation is more convenient, consequently also can reduce the alignment degree of difficulty between breach 5 and the bolt. Preferably, a magnet 11 is disposed in the slot 10 of the adaptor 8 and is engaged with the rotating shaft 9, and when the rotating shaft 9 is inserted into the adaptor 8, the rotating shaft 9 and the magnet 11 attract each other. Utilize setting up magnet 11 in the slot 10 to let and possess the adsorption between adaptor 8 and the cutter body 1, let pivot 9 can adsorb on adaptor 8, and then avoid cutter body 1 to drop when the installation and lead to the damage.

The above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited to the above embodiments, and all technical solutions that belong to the idea of the present invention belong to the scope of the present invention. It should be noted that modifications and embellishments within the scope of the invention may occur to those skilled in the art without departing from the principle of the invention, and are considered to be within the scope of the invention.
