Abstract
The invention discloses a machine tool for machining annular grooves at the outside diameter of a split lock bearing, which is characterized in that a positive and negative double cutter block is arranged on a special cutter rest of a machine tool spindle; an auxiliary base plate is transversely arranged on an operating surface of the machine tool, and a wheel seat is placed on the auxiliary base plate of a rotating disk of the operating surface and can rotate freely; two pressing plates are pressed on a workpiece and fixed on the wheel seat, the center of the workpiece is concentric with the machine tool spindle, and the workpiece, the wheel seat and the auxiliary base plate are arranged in an evenly-divided circular groove of an indexable cylindrical surface on the operating surface of the machine tool; when the machine tool spindle is provided with the positive and negative double cutter block, the circular grooves are machined, a circular groove can be machined and formed at one time, and the next circular groove is machined after the workpiece rotates a bisector; and two rounding chamfers of an outer opening of the circular groove are machined by a 90-degree dual-blade alloy cutter, and can be turned and molded at one time. The machine tool of the invention has the advantages of simple structure, good machining quality, high efficiency, capability of adapting to batch production, low cost, and capability of being most suitable to be applied to small and medium-sized enterprises or professional production, and is convenient in operation.
Description
Technical field
The present invention relates to the bearing process equipment, be specifically related to a kind of subdivision locking bearing outer-diameter ring shape groove machining tool.
Background technology
For LSL type subdivision locking bearing, the processing locking slot is a technical barrier.
1. be placed on and do on the boring machine that the tire working (machining) efficiency is too low, processing cost is too high;
2. be placed on CQ6180 and add on the lathe and process, floral disc adds bent plate on the needs, adopts narrow cutter turning, shakes big, unstable, the bad measurement of inner and outer rings size, operating efficiency is too low, and is high to operator's technical merit requirement, labour intensity is big, more incompatible batch process, and production efficiency is low.
Summary of the invention
The present invention discloses a kind of subdivision locking bearing outer-diameter ring shape groove machining tool, solve the problems of the technologies described above, specifically take following technical scheme: double-pole piece or is installed anyway 90 ° of alloy knife pieces of twolip on the lathe cutterhead, but workpiece is installed on the platen face in the branch circular groove such as calibration periphery.
Described cutter piece should the row of mill be cut groove, is met the interior outside dimension of processed cannelure, and front edge is by flat, reconditioning relief angle.
Described cutterhead inserts spindle taper hole, and usefulness hang spring bar is tight at the rear end of main shaft handle with cutterhead;
A horizontal subbolster above the described Lathe bench face, placenta is fixed on the rotating disc subbolster of work top, can rotate freely; Two pressing plates are pressed on the workpiece on placenta, and workpiece centre is concentric with main shaft.
Helpful being of the present invention: but since workpiece be fixed on the Lathe bench face in the branch cannelure such as calibration periphery, at lathe spindle the double-pole piece being installed anyway processes simultaneously, machine tool structure is simple, easy and simple to handle, crudy good, efficient is high, adapt to produce in batches, and cost is low, the application of the most suitable medium-sized and small enterprises or professional production.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Fig. 1 is the processing critical piece
Fig. 2 is the concrete schematic diagram of implementing
Among the figure: workpiece 1, outer shroud chamfering 2, interior ring chamfering 3, cannelure 4, pressing plate and bolt 5, cutter piece 6, cutterhead seat 7, main shaft 8, hang spring bar and emitted 9, subbolster 10, placenta 11, feeding handwheel 12.
The specific embodiment
As shown in Figure 1, workpiece 1 size (dimensional units is mm, and is as follows) scope: external diameter φ 200～600, height 30～200, outer shroud φ 40～70, interior ring φ 30～50.Can process the many five equilibriums and the cannelure 4 of five equilibrium not at workpiece 1 external diameter.
Embodiment:
Processing work 5 sizes:
Outer groove: φ 65+0.10 (circumference six five equilibriums);
Inner groove: φ 50+0.10 (circumference six five equilibriums);
Cannelure groove depth: 7.6+0.1;
Outer shroud chamfering: 2.9 * 45 °;
Interior ring chamfering: 2.1 * 45 °.
As shown in Figure 2, the present invention divides the transformation of the way and operation two parts to prevailing C620 lathe:
1. the chuck on the lathe spindle 8 is dismantled, utilize main shaft 8 taper holes that special-purpose cutterhead seat 7 is installed, two W18Gr4 cutter pieces, 6 positive and negative being installed on cutterhead seat 7 knife rests, cutter piece 6 is arranged well at cutlery grinding machine sharpening in advance and is cut groove, the back is milled to the interior outside dimension of processed cannelure 4 on the M1432 grinding machine, again with abrasive wheel end face with the front edge of cutter by putting down, hand grinding relief angle on abrasive machine at last, cutterhead seat 7 is inserted main shafts 8 taper holes, emitted 9 the rear end of cutterhead seat 7 at main shaft 8 fastened with hang spring bar and quilt.
With the last end carriage complete removal of lathe rotating disc, on carriage, utilize two silk holes below the former knife rest, subbolster 10 is in the above horizontal; Placenta 11 is placed on the rotating disc subbolster 10 of work top, utilize two hang springs on the rotating disc and the boring in the middle of the subbolster 10, find main shaft 8 centers accurately and align, 3 fixing placentas 11, the opening part of placenta 11 cooperates with workpiece 5 internal diameters, can rotate freely; But workpiece 5, subbolster 10 and placenta 11 are installed on the Lathe bench face in the branch circular groove such as calibration periphery.
2. be carved with bisector on the placenta 11, for example to circumference six bisectors, be pressed on the workpiece 5 tightly on carcass 11 by two pressing plates and bolt 6, workpiece 5 centers are concentric with main shaft 8.Axial feed handwheel 12 is increased to φ about 450, and cutter piece 6 contacts with workpiece 5, and determine cannelure 4 degree of depth, puts one 300 Steel Ruler on guide rail, rotates handwheel 12 feedings gently, and the cutter head cutting fluid is for foot, but groove of machine-shaping once.Unclamp pressing plate and bolt 6 after returning, five equilibrium of workpiece 5 rotations is clamping platen and bolt 6 again, processes next cannelure 4.After this batch workpiece 5 processed, last workpiece 5 was not opened pressing plate and bolt 6, enters subsequent processing.
Following operation is the outer shroud chamfering 2 and the interior ring chamfering 3 of processing cannelure 4 collar extensions; With two cutter pieces, 6 dismountings of cutterhead seat 7, change 90 ° of alloy knifes of a twolip on a cutter groove therein, a sword makes a sword to the external diameter peak to the internal diameter peak, all is 45 with cannelure 4 faces.Main shaft 8 rotating speeds about 200 commentaries on classics/min, a turning moulding.
