Background

Roller bearings are one type of rolling bearings, and are one of the components widely used in modern machinery. In the process of finish machining of a rolling ring of a roller bearing, because the rolling ring needs to be drilled in the radial direction and the axial direction, the traditional method is that the rolling ring is firstly installed on a machine tool, after holes in one direction are drilled, the rolling ring is disassembled to change the direction and then is installed on the machine tool to drill holes in the other direction, the installation and disassembly processes are complicated, the working efficiency is low, and the position precision of the holes in the two directions is influenced due to certain errors caused by different times of installation; although the existing tool or fixture can realize radial and axial punching in one-time installation, the structure is complex, the manufacturing cost is high, and the installation and disassembly processes are complicated. Therefore, a device which has a simple structure, low cost, high assembly and disassembly efficiency and can radially and axially punch in a single installation is needed.

Disclosure of Invention

An object of the utility model is to overcome the aforesaid not enough, provide a simple structure, need not to install many times and dismantle and can accomplish the circle class of the radial, axial processing of punching of rolling circle and punch and use frock.

The purpose of the utility model is realized like this:

a tool for punching circles comprises a base, a supporting plate vertically and fixedly arranged on the base, a plurality of positioning columns uniformly distributed on the supporting plate, and positioning sleeves sleeved on the positioning columns; the positioning columns are positioned on the same circumference; the outer circle of the positioning sleeve is positioned on the circumference of a concentric circle which is consistent with the positioning column, the center of the concentric circle is provided with a positioning screw rod, and a clamping rod and a rotary clamping nut are sequentially sleeved on the positioning screw rod;

the utility model relates to a circle punching tool, the central line of a positioning column is vertical to the plane of a supporting plate, and the central line of the positioning column is parallel to the plane of a base;

the utility model relates to a ring punching tool, the length of the clamping rod is larger than the excircle diameter of the rolling ring;

the utility model relates to a circle punching tool, wherein the base is provided with an installation hole site;

the utility model relates to a circle class punches and uses frock, be equipped with the strengthening rib between backup pad and the base.

When the clamping device works, the rolling ring is sleeved on the outer ring of the positioning sleeve, the inner ring of the rolling ring is ensured to be in close contact with the outer ring of the positioning sleeve, the clamping rod is sleeved on the positioning screw rod and presses the rolling ring, and the clamping nut is screwed to enable the fixed position of the rolling ring not to be sent; mounting the tool for clamping the rolling ring on a chuck of a machining center through a mounting hole; the chuck is rotated to ensure that the rolling ring is in a horizontal state, a vertical drill bit of a machining center drills out an axial counter bore on the edge of the rolling ring, then the chuck is rotated to enable the rolling ring to rotate by a certain angle, and a side milling head is utilized to drill out a radial counter bore in the direction towards the outer side of the inner side of the rolling ring, so that the punching operation is completed.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses simple structure, cost are low, roll the convenient quick of circle installation dismantlement, make through rotatory frock roll the circle by the axial position conversion of punching radially punch the position, realized that the single installation can accomplish radial axial and punch, improved and rolled the circle work efficiency that punches.
