Abstract

The utility model provides a lathe for processing circular grooves on an outside diameter of a split locking bearing. A special cutter head rest of a main shaft of the lathe is provided with reverse and forward double-blade block; the working table top of the lathe is transversely provided with an auxiliary base plate; a mould seat is arranged on a rotating disk auxiliary base plate on the working table top and is capable of freely rotating; two pressing plates are pressed on a workpiece and are fixed on the mould seat; the center of the workpiece is concentric with the main shaft; the workpiece, the mould seat and the auxiliary base plate are arranged in divisibility excircle surface equant circular grooves on the working table top of the lathe; the main shaft of the lathe is provided with the reverse and forward double-blade block to carry out processing at the same time, and thus, one circular groove can be processed and molded at a time; the next one circular groove is processed after the workpiece rotates by one halving; and two chamfers of the outside mouths of the circular grooves are processed by a double-edge 90 degree alloy knife and are turned and molded at a time. The lathe has the advantages that the structure is simple, the processing quality is high, the efficiency is high, the manufacturing cost is low, and the operation is simple and convenient, is suitable for volume production, and is most suitable for small and medium-sized enterprises or specialized production.

Description

Subdivision locking bearing outer-diameter ring shape groove machining tool

Technical field

The utility model relates to the bearing process equipment, is 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 utility model provides 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 utility model: 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 utility model is described in further detail.

Fig. 1 is the workpiece front elevational schematic;

Fig. 2 is the workpiece schematic top plan view;

Fig. 3 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 and Figure 2, 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:

Workpiece 1 size:

Outer shroud: φ 65+0.10 (circumference six five equilibriums);

Interior ring: 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 3, the utility model 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 1 internal diameter, can rotate freely; But workpiece 1, 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 1 tightly on carcass 11 by two pressing plates and bolt 6, workpiece 1 center is concentric with main shaft 8.Axial feed handwheel 12 is increased to φ about 450, and cutter piece 6 contacts with workpiece 1, 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 1 rotation is clamping platen and bolt 6 again, processes next cannelure 4.After this batch workpiece 1 processed, last workpiece 1 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.
