Abstract

The invention relates to a method for machining a groove in a hole. The method includes the steps that (1) a part is installed on an eccentric bushing so as to be driven by adhesive tape to rotate, a digging knife installed in an eccentric bushing hole is driven by a handle to rotate, and a blade of the digging knife gradually extends out of a groove of the cut part; (2) a mechanism is installed on a sleeve of a boring mill, the sleeve forwards moves so that a positioning sleeve is stopped by an end face of a workpiece, a stretchable knife rod does not forwards move any more through a locking nut, an outer sleeve, a thrust ball bearing, a stopping mat, a deep groove ball bearing, a sliding sleeve and a pin, a main shaft of the boring mill rotates to forwards move, the boring cutter moves in the radial direction under the effect of an inclined hole in a cutter body, and a groove in a large part hole is bored; and (3) deep and wide grooves in the hole are bored through mechanisms installed at the front end of the main shaft of the boring mill and a boring bar of the main shaft, a boring mill working table is moved to install a groove boring cutter at the position of the groove in the large part hole in the working table in an aligned manner, a gear rotates through an axial rack installed on the boring bar of the main shaft, the radial rack is driven to move, radial cutter feeding of the groove boring cutter is achieved, and cutting of the groove in the hole is completed. A qualified groove in a round hole can be rapidly and conveniently machined, the cost is low, and the efficiency is high.

Description

The processing method of hole inside groove

Art

The present invention relates to the processing method of engineering goods parts, especially the processing method of hole inside groove.

Background technology

In machine-building some box parts endoporus in have need processing groove, as circlip for hole groove, O type ring recess.Be not suitable with and process on lathe.Boring machine adds man-hour, requires that boring cutter has the function of radial feed.Some boring machines do not have this mechanism, even if some boring machines have depth-feed mechanism, mechanism changes cumbersome, and if do not designed mechanism supporting with it, the efficiency of processing parts is low, of poor quality.

Summary of the invention

The object of the invention is the defect overcoming prior art, the processing method of several holes inside groove is provided, certainly can process the groove in circular hole fast, reliably.

The object of the invention is to realize as follows: the processing method of hole inside groove relates to part, dig cutter, eccentric bushing, adhesive tape, handle, cutter hub, sliding sleeve, pin, deep groove ball bearing, thrust ball bearing, workpiece, boring cutter, positioning sleeve, locking nut, overcoat, gear pad, Telescopic knife bar, main shaft, boring bar, axial tooth bar, gear, radial tooth bar, boring tool and large part, it is characterized in that: the 1) processing of aperture inside groove: part is contained on eccentric bushing and uses adhesive tape driven rotary, the cutter that digs be contained in eccentric trepanning rotates under the drive of handle, the blade digging cutter stretches out the groove cutting part gradually, 2) with groove narrow, shallow in depth-feed mechanism boring macropore hole in piece part: mechanism is contained on the sleeve of boring machine, the sleeve positioning sleeve that travels forward is blocked by the end face of workpiece, by locking nut. overcoat, thrust ball bearing, gear pad, deep groove ball bearing, sliding sleeve and pin make Telescopic knife bar no longer travel forward, boring spindle is rotating and moves forward, under the effect of the inclined hole on cutter hub, boring cutter moves radially, and the groove boring in macropore hole in piece part is become, 3) processing method of dark, the sipes in hole: with dark, sipes in the mechanism's bore hole be contained on boring spindle front end and main shaft boring bar, moving boring machine workbench aims at the position of the groove in dress large hole in piece part on the table boring tool, the axial tooth bar be contained on main shaft boring bar makes pinion rotation, radial tooth bar is driven to move, and then make boring tool radial feed, complete the cutting of the groove in hole.

The invention has the beneficial effects as follows, can process the groove in qualified circular hole quickly and easily, cost is low, efficiency is high.

Detailed description of the invention

1) processing of aperture inside groove: in Fig. 1, Fig. 2, the endoporus of part (1) only has φ 6 millimeters, and the maximum gauge of groove 9.2 millimeters, can not complete by common processing method.On special equipment, part (1) is contained on eccentric bushing (3), by adhesive tape (4) driven rotary, the cutter (2) that digs be contained in eccentric bushing (3) hole rotates under the drive of handle (5), the blade digging cutter (2) stretches out gradually, cuts the groove of part (1).Terminate back handle (5) and get back to origin-location, exit within digging the cylindrical of blade plant eccentric bushing (3) of cutter (2);

2) with narrow in depth-feed mechanism boring macropore hole in piece part, shallow groove: in figure 3, mechanism is contained on the sleeve of boring machine driving shaft, sleeve travels forward, positioning sleeve (13) is blocked by the end face of workpiece (11), by locking nut (14). overcoat (15), thrust ball bearing (10), gear pad, 16), deep groove ball bearing (9), sliding sleeve (7) and pin (8) make Telescopic knife bar (17) no longer travel forward, boring spindle is rotating and moves forward, under the effect of the inclined hole on cutter hub (6), boring cutter (12) moves radially, groove boring in workpiece (11) hole is become, after completion, sleeve is return, and boring cutter (12) resets.

3) processing method of dark, the sipes in hole: in the diagram, because the groove in hole is not only dark but also wide, process it and could realize with special device.With the device of boring bar (19) taper hole be contained on boring spindle (18) front end and main shaft, dark, sipes in bore hole: moving boring machine workbench aims at the position of the groove in dress large part (24) hole on the table boring tool (23), the axial tooth bar (20) be contained on main shaft boring bar (19) makes gear (21) rotate, drive radial tooth bar (22) mobile, make boring tool (23) radial feed, complete the cutting of the groove in hole.Reset stepped back by boring bar (19), and large part (24) is return.
