The special top clamping device is composed of a poking block, a locating seat, a tip, a tip sleeve, conical roller bearings and locating tapered rods, wherein locating tapered rods are movably mounted in the tip sleeve through symmetrically arranged conical roller bearings, the poking bolt is arranged on the tip sleeve, the locating seat is arranged on one side of the tip sleeve, the poking block is mounted at the end head of the locating seat through a fixing bolt, and the locating seat between the poking block and the tip sleeve is sleeved with the tip. According to the special top clamping device for grinding the outer circle of the gear shaft, the poking rod of a traditional heart carrier is replaced by the poking block as the transmission medium, so that the time for assembling and disassembling the heart carrier by an operator is saved; compared with prior art, the special top clamping device for grinding the outer circle of the gear shaft has the advantages of ecumenical cost, rapid in clamping interval and good in stability, saves clamping time, ensures product machining accuracy and does not damage products in clamping, thus being particularly applicable to machining grinding gear shafts of gear rack steering device.
Description
Technical field
The utility model relates to a kind of Special top clamp device of grinding worm axle cylindrical, belongs to automobile steering device parts Fixture Design technical field.
Background technology
Increasingly competitive along with automobile industry, improves product processing beat and automaticity, reduces labor intensity and has become at present the subject matter that each auto parts and components manufacturer pays close attention to.
In the gear shaft Grinding Process of existing rack and pinion steering gear, the installation way of grinding worm axle bearing position is mainly heart carrier clamping, uses heart carrier clamping workpiece to mainly contain the shortcoming of the following aspects:
1, operator need to repeat continuous upper and lower chuck, the time of waste lifting workpiece;
2, the action of lower chuck in operator's operation repeatedly, need to operate thousands of every day, and labour intensity is high.
3, heart carrier screw clamping workpiece place can crush workpiece too firmly, and too soft dynamics not can not clamping work pieces.
Above 3 is the ubiquitous problems of axial workpiece such as numerically control grinder processing gear shaft.
In order to eliminate above shortcoming, be necessary to research and develop a kind of time that can save the upper and lower heart carrier of operator, can ensure again processing precision of products (size and axiality), not make again the center special of the grinding worm axle cylindrical that does not use heart carrier clamping that product crushes simultaneously.
Summary of the invention
The purpose of this utility model is: provides a kind of simple in structure, easy to operate, both saved the clamping time, can ensure again processing precision of products, do not make again product crush simultaneously, and the Special top clamp device of cheap grinding worm axle cylindrical.
The utility model is to realize by following technical solution above-mentioned purpose:
A Special top clamp device for grinding worm axle cylindrical, it is made up of shifting block, positioning seat, top, tailstock sleeve, taper roll bearing and locating cone bar; It is characterized in that: in tailstock sleeve, be movably installed with locating cone bar by symmetrically arranged taper roll bearing, on locating cone bar between taper roll bearing, packing ring is installed, on the tailstock sleeve corresponding with packing ring, be provided with and stir bolt, tailstock sleeve one side is provided with positioning seat, the termination of positioning seat is provided with shifting block by set bolt, on positioning seat between shifting block and tailstock sleeve, be set with toply, be toply fixedly connected with tailstock sleeve.
The utility model beneficial effect is compared with prior art:
The utility model replaces the driving lever of traditional heart carrier taking shifting block be driving medium, save the time of the upper and lower heart carrier of operator, there is compared to existing technology cost economic, clamping beat is fast, the advantage of good stability, both saved the clamping time, can ensure again processing precision of products, not make again product crush, the gear shaft grinding that is specially adapted to rack and pinion steering gear is used simultaneously.
Brief description of the drawings
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is side-looking structural representation of the present utility model.
In figure: 1, shifting block, 2, positioning seat, 3, top, 4, tailstock sleeve, 5, taper roll bearing, 6, locating cone bar, 7, packing ring, 8, stir bolt, 9, set bolt.
Detailed description of the invention
The Special top clamp device of this grinding worm axle cylindrical, it is made up of shifting block 1, positioning seat 2, top 3, tailstock sleeve 4, taper roll bearing 5 and locating cone bar 6.In tailstock sleeve 4, be movably installed with locating cone bar 6 by symmetrically arranged taper roll bearing 5, on the locating cone bar 6 between taper roll bearing 5, packing ring 7 be installed, packing ring 7 mainly works to separate two bearings.On the tailstock sleeve 4 corresponding with packing ring 7, be provided with and stir bolt 8.Tailstock sleeve 4 one sides are provided with positioning seat 2, and the termination of positioning seat 2 is provided with shifting block 1 by set bolt 9, be set with top 3, top 3 and be fixedly connected with tailstock sleeve 4 on the positioning seat 2 between shifting block 1 and tailstock sleeve 4.
The Special top clamp device locating cone bar 6 of this grinding worm axle cylindrical is the center support of top clamp device, top 3 and tailstock sleeve 4 of carbide alloy material are welded, taper roll bearing 5 and packing ring 7 are housed on the locating cone bar 6 in tailstock sleeve 4, thereby the axiality that makes locating cone bar 6, taper roll bearing 5, tailstock sleeve 4 and top 3 is benefited and ensured, and use taper roll bearing 5 can ensure still to ensure the position in axle center after bearing wear.
When the Special top clamp device of this grinding worm axle cylindrical uses, be installed on by locating cone bar 6 in the center hole of machine tool headstock.The shifting block 1 of this Special top clamp device is the shifting part of gear shaft (workpiece) internal tooth, and clamping is sleeved in the internal tooth of gear shaft shifting block 1, rotates with driven gear axle.When work, the top collaborative gear shaft that withstands of top 3 and the numerically control grinder other end of this Special top clamp device, in the time that lathe driving lever rotates, drive and stir bolt 8 and rotate, thus drive tailstock sleeve 4, top 3 and shifting block 1 rotate with boat, thus by the feeding grinding gear shaft product of grinder wheel.
The Special top clamp device of this grinding worm axle cylindrical is applicable to the gear shaft product processing of different model, solve the loaded down with trivial details problem of existing gear shaft clamping heart carrier, save the time of lifting workpiece, reduced labour intensity, also avoided heart carrier to crush the risk of workpiece simultaneously.
