Abstract
Cylindrical roller bearing retainer square hole cutting jig belongs to the cylindrical roller bearing retainer processing technology field. It includes chuck and chuck complex anchor clamps seat, the chuck head is three lamella structures of open type, three lamella structure fit ins of open type set up the internal expanding dabber, internal expanding dabber afterbody and chuck threaded connection, the chuck sets up the round locating hole with cooperation department of anchor clamps seat, setting and arbitrary one through -hole that the locating hole corresponds in the anchor clamps seat, the through -hole sexual copulation locking ball of being hit by a bullet, locking ball and the cooperation of locating hole joint, the chuck afterbody cup joints and sets up regulating spring, regulating spring one end and the cooperation of anchor clamps seat, the other end cooperates with the spring holder that sets up on the chuck. Can fix the cylindrical roller bearing retainer column rule cutting process that goes forward side by side through these anchor clamps, this chuck head be three lamella structures of open type simultaneously, can be fit for not unidimensional holder and process, and the chuck can rotational positioning, has guaranteed the machining precision.
Description
Technical field
The utility model belongs to cylinder roller bearing retainer processing technique field, is specifically related to cylinder roller bearing retainer square hole cutting clamper.
Background technology
Some is not suitable for broaching processing because of reasons such as its wall thickness, square hole are little cylinder roller bearing copper retainer square hole. Therefore, in the time that cylinder roller bearing copper retainer is carried out to square hole working, need to adopt line cutting processing mode to process, but in prior art, can not ensure that the special fixture of retainer precision is for the line cutting processing of retainer.
Utility model content
The problem existing for prior art, the purpose of this utility model is that design provides the technical scheme of cylinder roller bearing retainer square hole cutting clamper.
Described cylinder roller bearing retainer square hole cutting clamper, the clamping fixture seat that it is characterized in that comprising chuck and be socketed in chuck afterbody, described chuck head is open type three valve structures, in described open type three valve structures, be equipped with internal expanding mandrel, described internal expanding mandrel afterbody is threaded with chuck, described chuck and clamping fixture seat cooperation place arrange a circle hole, the through hole corresponding with any one locating hole is set in described clamping fixture seat, described through hole Elastic coordinates locking ball, described locking ball coordinates with locating hole clamping, described chuck afterbody socket arranges regulating spring, described regulating spring one end coordinates with clamping fixture seat, the other end coordinates with the spring base being arranged on chuck.
Described cylinder roller bearing retainer square hole cutting clamper, is characterized in that described internal expanding mandrel and open type three valve structure auxiliary sections are cone structure.
Described cylinder roller bearing retainer square hole cutting clamper, is characterized in that on described through hole, being fixedly installed location regulates spiral shell, and described location tightens screw and connects normal dog, and described normal dog connects locking ball.
Above-mentioned cylinder roller bearing retainer square hole cutting clamper, simple in structure, reasonable in design, can fix the cylinder roller bearing retainer line cutting processing of going forward side by side by this fixture, this chuck head is open type three valve structures simultaneously, can be applicable to the retainer processing of different size, chuck can rotate location, has ensured machining accuracy.

Detailed description of the invention
Further illustrate the utility model below in conjunction with Figure of description.
As shown in the figure, cylinder roller bearing retainer square hole cutting clamper comprises chuck 3 and the clamping fixture seat 5 that is socketed in chuck 3 afterbodys. Chuck 3 heads are open type three valve structures 302, adopt this flexible head, can make the retainer 1 of its clamping different inner diameters. In open type three valve structures 302, be equipped with internal expanding mandrel 2. Internal expanding mandrel 2 is cone structure with open type three valve structure 302 auxiliary sections, carrys out tensioner regulate open type three valve structures 302 by this conical surface, and internal expanding mandrel 2 afterbodys are threaded with chuck 3. For the ease of regulating internal expanding mandrel 2, the head end of internal expanding mandrel 2 is also provided with interior six sides, and with rotate screw thread with spanner. Chuck 3 arranges a circle hole 301 with clamping fixture seat 5 cooperation places, and the through hole 501 corresponding with any one locating hole 301 is set in clamping fixture seat 5. On through hole 501, be fixedly installed location and tighten screw 7, location tightens screw 7 and connects normal dog 6, and normal dog 6 connects locking ball 4, and locking ball 4 coordinates with locating hole 301 clampings. Locate the locking degree that tightens screw 7 and regulate locking ball 4 by adjustment. Chuck 3 afterbody sockets arrange regulating spring 8, and regulating spring 8 one end coordinate with clamping fixture seat 5, and the other end coordinates with the spring base 9 being arranged on chuck 3. By regulating regulating spring 8 to adjust the fitness of chuck 3 and clamping fixture seat 5, so that chuck 3 is can flexible rotating again can not gap too large.
When use, retainer 1 is socketed on open type three valve structures 302 of chuck 3, and by regulating internal expanding mandrel 2 fastening retainers 1, fixing laggard line cutting. In the time need to carrying out the cutting of next square hole, pull clamping fixture seat 5, rotary chuck 3, makes next locating hole 301 and locking ball 4 clamping location on chuck 3.
