Description
Technical field
The utility model belongs to bearing retainer process tool technical field, is primarily related to a kind of special-shape bearing holding
Frame pocket hole hold depth tool.It is mainly used in the processing of cylinder roller bearing cage pocket hold depth.
Background technology
There are two types of processing methods for usual bearing retainer pocket hole hold depth:Bronze material retainer hold depth is generally by idler wheel
The deformation methods such as extruding, rolling, make cage bar be plastically deformed, are dropped out from retainer internal diameter or outer diameter with lockking roller;Steel
Retainer (40CrNiMoA) is at the internal diameter or outer diameter boss of retainer pocket hole both sides mostly, and design is arc-shaped with R
Slot bends groove edge, to lock rolling element, is allowed to become inseparable component with retainer.The general method for using milling
Process internal diameter or outer diameter R slots (i.e. hold depth pawl).
The hold depth of special-shape bearing retainer is to design processing " W " type groove in retainer inner radius, due to material hardness height
(40CrNiMoA steel alloys), the deformation method of idler wheel extruding, rolling can not be used to be processed, and " W " type groove recess is in internal diameter
On the inside of step, if the method using milling is processed, milling cutter will be interfered with step in workpiece, influence processing flow;If right
" W " type groove uses electrical discharge machining, and surface may be caused to generate micro-crack, cannot be satisfied product quality requirement, therefore existing
Processing technology cannot achieve the processing of " W " type groove, and make " W " type groove is processed into a great problem.
Utility model content
Thus the purpose of this utility model generates, propose a kind of special-shape bearing retainer pocket hole hold depth tool, leads to
Design specialized cutting tool, cutter holder are crossed, solves the processing problem of special-shape bearing retainer internal diameter " W " type groove, is realized special-shaped
The processing of bearing retainer internal diameter " W " type groove.
To achieve the above object, the technical solution adopted in the utility model is:A kind of special-shape bearing retainer pocket hole hold depth
Tool, including the top of cutter holder, cutting tool, the cutter holder is staight shank, lower part is folder cutter groove, and presss from both sides cutter groove
Opening sets screw positioned at the side of cutter holder on the cutter holder, and shank portion and the folder cutter groove of the cutter pass through screw
The outside of folder cutter groove is extended in connection, tool bit part, and front end has cutting tooth.
Further, the folder cutter groove is round outside but spuare inside structure.
Further, the tool bit part of the cutter is taper, and the cutting tooth is located at the front end of taper cutter head.
Further, width with workpiece " W " groove depth shape of the cutting tooth matches.
Further, the anterior angle angle of the cutter is 0 °~3 °, relief angles are 20 °~30 °
Further, the handle of a knife of the cutter is rectangle structure.
Further, the staight shank with machining center main shaft on the cutter holder top are connect by ER elastic collets.
The utility model is mainly different for the steel of " W " type groove by design specialized cutting tool, cutter holder solution internal diameter
Type bearing retainer processes problem, and the anisotropic bearing that material hardness can be avoided excessively high using high rigidity cutting tool is being processed
The problem of " W " type groove can not process, using the function of the quick forward and back of machining center, to workpiece diameter when can effectively avoid processing
Interference, cutting tool movement locus is accurately set using macroprogramming, can avoid processing when caused by product quality
It influences, which can effectively improve anisotropic bearing machining level and ability, and processes and lead in steel retainer pocket hole hold depth
Realize innovation in domain.

Specific implementation mode
In conjunction with attached drawing, the utility model is further described by way of embodiment.
As shown in Figure 1, a kind of special-shape bearing retainer pocket hole hold depth tool described in the present embodiment is existing
Cutter 3 is connected with by cutter holder 2 on the central principal axis 1 of machining center.The top of the cutter holder 2 be φ 12mm staight shanks 7, under
Portion be round outside but spuare inside folder cutter groove 5, and press from both sides cutter groove 5 opening positioned at cutter holder 2 side, the cutter holder 2 axial direction and
Radial direction be both provided with screw 6 for connect with clamp-on tool 3, wherein axial bolt is two, radial screw is one.The folder
The staight shank 7 on 2 top of knife device is connect with machining center main shaft 1 by ER elastic collets, easy to disassemble.The cutter 3 selects tungsten high
Fast steel (W18Cr4V) makes, and handle of a knife 8 is rectangle structure, sectional dimension 10mm × 10mm × 38mm, with linear cutter, knife
Head is taper, in taper cutter head front end there is cutting tooth 9, the width of the cutting tooth 9 to match with workpiece " W " groove depth shape.
The anterior angle angle of the cutting tool is 0 °~3 °, relief angles are 20 °~30 °.8 part of handle of a knife of the cutter 2 is by folder knife
The opening of 2 side of device inserts in folder cutter groove 5, is fixed to clamp by two axial bolts and a radial screw of cutter holder 2.Institute
It is the prior art to state machining center, can be RFMV105 (3+2) machining center.
When the utility model is used, after cutting tool being fixed with cutter holder, on clamping work in-process heart main shaft, while profit
Control retainer pocket hole decile with C indexing, when work, machining center carries out precision programming with macroprogram, cutting tool with
