Abstract
The utility model belongs to a jig fixture which is used for processing draw holes of a centering roller bearing solid cage, which mainly comprises a transitional rotary table (2), a supporting plate (3), a pressure plate (5), a gantry (6) and a pressure column (7), wherein the transitional rotary table (2) is fixed on a machine tool guide way, the bearing plate (3) is fixed on the transitional rotary table (2), the pressure plate (5) is arranged on the upper portion of the bearing plate (3), the gantry acts on the pressure plate (5) through the pressure column (7), wherein the upper flat surface of the transitional rotary table is an inclined surface which has an angle (a) with the bottom level surface, the bottom surface of the supporting plate (3) is corresponding with the upper flat surface of the transitional rotary plate (2), a positioning shaft is arranged on the transitional rotary table, and a through groove is arranged in the supporting plate. The fixture utilizes the included angle between a pocket and the end surface to enable a broaching tool to be extended from the other end surface of a work piece after the broaching tool broaches a hole, and forces the broaching tool to cut the work piece tooth by tooth to complete the broaching process of the work piece, thereby the accuracy of each terms after the hole is broached satisfies the requirements of the product.
Description
Technical field
The utility model belongs to technical field of bearings, relates generally to a kind of frock clamp that is used for the processing of self-aligning roller bearing solid cage pulling eye.
Background technology
Self-aligning roller bearing retainer great majority in the past is a stamping parts, and material mostly is mild steel greatly, and also some adopts brass, bronze and aluminum alloy materials, and structure is end face bore mode or shaped as frame retainer, and its scope of application is restricted.Along with the development of national defense industry, also can appear at various occasions to high speed, high strength, high-precision bearing, this just requires our higher requirement of having selected for use to bearing material.Now adopt solid-drawn retainer structure, machined material is 40CrNiMoA, and the characteristics of this material are that intensity is higher, anti-wear performance is good, the machining property extreme difference, and material more in the past has tangible difference, especially as pulling eye retainer material, and the retainer required precision is high.Self-aligning roller bearing solid-drawn retainer structure as shown in Figure 1, characteristics are that outer image is bowl-shape, and pocket hole profile cross section is taper, and two sides are arc surface, and the dimensional accuracy height has brought bigger difficulty for like this design processing of technology, frock and cutter.
Summary of the invention
The purpose of this utility model provides a kind of frock clamp that is used for the processing of self-aligning roller bearing solid cage pulling eye, and it can be processing retainer pocket pore area and comes conveniently.
The technical scheme that its technical problem that solves the utility model adopts is: it mainly is made of transition rotating disk, supporting disk, platen, portal frame and compression leg, the transition rotating disk is fixed on the machine tool guideway, supporting disk is fixed on the transition rotating disk, platen is arranged on supporting disk top, depression bar acts on the platen by portal frame, wherein the last plane of transition rotating disk is the inclined-plane that an angle is arranged with the bottom level mask, the bottom surface of supporting disk is consistent with the last plane gradient of transition rotating disk, the transition rotating disk is provided with locating shaft, is provided with one and runs through groove in supporting disk.
The utility model utilizes the angle of pocket hole and end face that below, broaching tool broaching Kong Houcong workpiece other end is drawn, and forces broaching tool to pursue the tooth cutting workpiece, finishes the broaching process of workpiece.Thereby make every precision behind the pulling eye reach the requirement of product.
Description of drawings
Accompanying drawing 1 is a self-aligning roller bearing solid cage pocket hole schematic diagram.
Accompanying drawing 2 is that the B of Fig. 1 is to view.
Accompanying drawing 3 is a structural representation of the present utility model.
Among the figure: 1, machine tool guideway 2, transition rotating disk, 3, supporting disk, 4, workpiece, 5, platen, 6, portal frame 7, depression bar, 8, broaching tool, 9, locating shaft, 10, run through groove.
The specific embodiment
In conjunction with the accompanying drawings, specific embodiment of the utility model is described.
As shown in Figure 3: the main transition rotating disk 2 of the utility model, supporting disk 3, platen 5, portal frame 6, depression bar 7 constitute, transition rotating disk 2 is fixed on the machine tool guideway, supporting disk 3 is fixed on the transition rotating disk 2, platen 5 is arranged on supporting disk 3 tops, depression bar 7 acts on the platen 5 by fixing portal frame 6, be provided with a locating shaft 9 at the middle part of transition rotating disk 2, the bottom surface of supporting disk is consistent with the last plane gradient of transition rotating disk, the last plane of supporting disk 3 is parallel with 1 of machine tool guideway, is provided with one and runs through groove in supporting disk 3.Transition rotating disk 2 is fixedlyed connected with machine tool guideway 1 with screw by locating shaft, and its working face becomes a angle with guide pass, and the locating shaft 9 on it has angle a with the machine tool guideway mask; Supporting disk 3 is felt relieved by locating shaft 9, and adopts bolt and transition rotating disk 2 to fix, and at this moment the angle of the workpiece support face of supporting disk 3 and guide pass is a angle equally; The groove that runs through in the supporting disk 3 becomes a angle with the workpiece support face, it is more bigger than pocket hole dimension that it runs through the well width size, effect is that broaching tool 8 is not interfered with supporting disk in the broaching process, and a cydariform step similar to retainer internal diameter shape arranged in the broaching tool porch, be in order to prevent the distortion of workpiece 4 in the broaching process, at this moment, run through groove 10 by back, anchor clamps location and machine tool guideway maintenance level, thereby guarantee that broaching tool moves in the horizontal direction.Its using method is after leader before the broaching tool passes the pocket hole of workpiece to be processed, and broaching tool 8 moves from right to left, makes broaching tool can carry out the broaching in a hole.Utilize the angle of pocket hole and end face that below, broaching tool broaching Kong Houcong workpiece other end is drawn, force broaching tool to pursue the tooth cutting workpiece, finish the broaching process of workpiece.
