Description

A special sleeve device for machining outer circle of boring machine

technical field

The utility model relates to a special sleeve device for machining an outer circle of a boring machine, which belongs to the technical field of machine tool machining tools.

Background technique

The ends of most large workpieces are short cylinders. Due to the large volume of the workpieces, small horizontal lathes cannot process the outer circle of the short cylinders at the ends, nor can ordinary boring machines be able to process them.

Utility model content

In order to solve the above-mentioned deficiencies in the prior art, the utility model provides a special sleeve device for machining the outer circle of a boring machine, which realizes the outer circle machining of a large workpiece by adding a sleeve device on the boring machine.

The technical scheme adopted by the utility model to solve the technical problem is as follows: a special sleeve device for machining an outer circle of a boring machine, which includes a sleeve, a tool seat, a boring machine tool handle, and a bolt; the sleeve is cylindrical, one end is closed, and the other end is open , The tool holder of the boring machine is tapered, the closed end of the sleeve and the tool holder of the boring machine are coaxially fixed and welded together, one side of the tool holder is longitudinally provided with a groove, and there are two threaded holes on the front. Bolts are arranged inside, and the opposite surfaces of the grooves of the cutter seat are fixed and welded on the end surface of the single side wall of the open end of the sleeve.

Install the boring machine tool holder of the sleeve device into the boring bar of the boring machine to connect it with the main shaft of the boring machine. The turning tool shank is inserted into the groove of the tool seat, the bolt is screwed into the screw hole on the front of the tool seat, and the bolt is tightened so that the turning tool shank is clamped in the groove. The spindle of the boring machine rotates, so that the turning tool on the tool holder feeds on the outer circle of the workpiece along the rotation direction of the spindle for processing.

The beneficial effects of the utility model are as follows: the special sleeve device for machining the outer circle of the boring machine is simple to manufacture and convenient to use, especially for machining large quantities of workpieces, which is simple and efficient, and greatly improves the production efficiency.

Detailed ways

As shown in Figure 1, a special sleeve device for machining an outer circle of a boring machine includes a sleeve 1, a tool holder 2, a boring machine tool holder 3, and a bolt 4; the sleeve 1 is cylindrical, one end is closed, and the other end is open. The handle 3 is tapered, the closed end of the sleeve 1 and the boring machine handle 3 are coaxially fixed and welded together, one side of the tool seat 2 is longitudinally provided with a groove, and the front has two threaded holes, the threaded holes are connected with the groove, and the thread Bolts 4 are arranged in the holes, and the opposite surfaces of the grooves of the cutter seat 2 are fixed and welded on the end surface of the single side wall of the open end of the sleeve 1 .

Specific operation method:

As shown in Figure 2, install the tool holder 3 of the boring machine into the boring bar 7 of the boring machine to connect with the spindle of the boring machine, install the tool holder of the turning tool 5 into the groove of the tool holder 2, and tighten the bolt 4 to clamp the turning tool 5. Turning tool holder; the rotation of the spindle of the boring machine makes the turning tool on the tool holder 2 feed on the outer circle of the workpiece 6 along the rotation direction of the spindle, so as to realize the outer circle of the workpiece processed by the boring machine.
