Description

Steering nut numerical control raceway milling machine toolsetting special tooling
Technical field
The utility model relates to mechanical, and particularly a kind of steering nut numerical control raceway milling machine toolsetting special tooling refers to a kind of steering nut numerical control raceway milling machine toolsetting special tooling that can reduce the workpiece waste product especially.
Background technology
The numerical control internal thread milling machine manufacturing procedure of steering nut is with CNC special purpose milling machine processing steering nut internal thread raceway, and the engaging tooth of internal thread raceway and steering nut has strict relative position requirement, because cutter for same is the special screw thread milling cutter; When more renewing cutter or refacing cutter; For Working position effectively being aimed at, when changing cutter, must carry out tool setting by the use-proved (performance-proved) pro-duct workpiece at every turn; Need this moment to use and produce the size that processes this operation with blank; And carry out measuring position, diameter dimension verification qualified after, just accomplish tool setting, have the generation of a waste product like this at least and caused waste.In order to solve the problem of above-mentioned generation waste product and waste, adopt the utility model overall appearance toolsetting special tooling consistent to substitute workpiece with processing work, meet the needs of production.
The utility model content
The purpose of the utility model is to provide a kind of steering nut numerical control raceway milling machine toolsetting special tooling; Be installed on the CNC special purpose milling machine during this frock toolsetting; Production miller headstock one end is provided with broach shell, and handle of a knife is installed on the broach shell, and handle of a knife connects the moulding internal thread milling cutter of a processing adjustment cover; The fixing one outer mold that can use repeatedly on the production miller headstock of the milling machine other end; The interior adjustment cover that edge can be changed at any time in the outer mold; And outer mold and interior adjustment are sheathed on the concentric axis; Interior adjustment cover and the diameter of work size that needs to process and consistent with the shape and the relative position size of workpiece engaging tooth, the profile of outer mold and institute's processing parts profile are consistent; Should be provided with and the consistent V-type groove of institute's processing parts profile by outer mold, the location clamp that is used for accurate location and clamping work pieces is clamped in the groove face of the V-type groove of outer mold.
During tool setting, adjustment cover in the processing of moulding internal thread milling cutter.Then, according to the qualified parameter of diameter dimension, shape and the relative position of interior adjustment cover, the cutter of adjustment moulding internal thread milling cutter on equipment mended parameter (being the position compensation rate), the batch machining production of realization workpiece.
The advantage of the utility model is:
1, outer mold can use repeatedly, has reduced the workpiece waste product;
2, interior adjustment cover can be changed at any time, can effectively guarantee the relative position between the engaging tooth of internal thread raceway diameter and itself and steering nut.
Description of drawings
Fig. 1 is the cutaway view sketch map of the outer mold rough of the utility model.
Fig. 2 is the cutaway view sketch map of the outer mold processing of the utility model back state.
Fig. 3 is the toolsetting view of the utility model.
Fig. 4 is the toolsetting state enlarged diagram of the utility model.
Fig. 5 is the utility model machining state sketch map.
The figure number implication: 1. outer mold, 2. in adjustment cover, 3. production miller headstock, 4. broach shell, 5. handle of a knife, 6. moulding internal thread milling cutter, 7. location clamp, 8.V type groove, 9. production miller main spindle box.
The specific embodiment
Shown in accompanying drawing 1 to accompanying drawing 5; Be the cutaway view sketch map of the utility model rough, cutaway view sketch map, toolsetting view, toolsetting state enlarged diagram and the machining state sketch map of processing back state; By can clearly be seen that be installed on the CNC special purpose milling machine during this frock toolsetting, an end of production miller headstock 3 is provided with broach shell 4 among the figure; Handle of a knife 5 is installed on the broach shell 4, and handle of a knife 5 connects the moulding internal thread milling cutter 6 of adjustment cover 2 in the processing; The fixing one outer mold 1 that can use repeatedly on the production miller main spindle box 9 of the production miller other end; The interior adjustment cover 2 that edge can be changed at any time in the outer mold 1; And outer mold 1 is located on the concentric axis with interior adjustment cover 2; In adjustment cover 2 and the diameter of work size that needs processing and consistent with the shape and the relative position size of workpiece engaging tooth, the profile of outer mold 1 is consistent with institute processing parts profile.Should be provided with and the consistent V-type groove 8 of institute's processing parts profile by outer mold 1, the location clamp 7 that is used for accurate location and clamping work pieces is clamped in the groove face of the V-type groove 8 of outer mold 1.
Shown in accompanying drawing 3 to accompanying drawing 5; Toolsetting view, toolsetting state enlarged diagram and machining state sketch map for the utility model; By can clearly be seen that among the figure, handle of a knife 5 is installed on the broach shell 4, handle of a knife 5 connects the moulding internal thread milling cutter 6 of adjustment cover 2 in the processing; The outer mold 1 that the production miller headstock 3 of the milling machine other end fixing can use repeatedly, the interior adjustment cover 2 that edge can be changed at any time in the outer mold 1, and outer mold 1 overlaps 2 with interior adjustment and be located on the concentric axis, the profile of outer mold 1 is consistent with institute processing parts profile.Rely on vertical forces to be clamped in the groove face of the V-type groove 8 of outer mold 1 by production miller one location clamp 7 self-contained, that be used to locate clamping; Accurately location and clamping work pieces, make workpiece the internal thread raceway diameter dimension and be in the tram with respect to the position dimension of engaging tooth, the adjustment tool position is to qualified; After accomplishing tool setting; Interior adjustment cover 2 is unloaded, and outer mold 1 continues to use, and carries out the batch machining of steering nut internal thread raceway.During each tool changing, adopt this frock, can effectively stop the waste product that causes because of toolsetting.
