Description
Technical Field
The utility model relates to a machining field, in particular to lathe deep hole processingequipment.
Background
Deep hole machining is machining of the diameter ratio of the length of a hole to the diameter of the hole to be larger than 10. The depth-diameter ratio L/d of the common deep hole is more than or equal to 100 in most cases. Such as cylinder bores, axial bores for shafts, rocket bodies, and barrels for various artillery pieces, etc. Some of these holes require high machining accuracy and surface quality, and some of the materials to be machined have poor machinability, which often becomes a difficult problem in production.
In present BTA, in order to guarantee BTA's accuracy, often practical more accurate BTA machine tool, this kind of lathe though can solve BTA's this difficult problem, but its equipment precision is high, and the cost of maintenance in earlier stage investment and later stage is all higher, is not conform to the economic value of little medium-sized enterprise.
SUMMERY OF THE UTILITY MODEL
The utility model provides a lathe BTA device, its simple structure, convenient operation, investment cost is low, convenient popularization.
In order to achieve the above object, the utility model adopts the following technical scheme:
the utility model provides a lathe BTA device, removes the tailstock including installing the lathe on the lathe guide rail, the lathe removes the tailstock and includes movable block and installation axle, the dop is installed and the installation is equipped with the drill bit on the dop to the front end of installation axle, install the epaxial adapter sleeve that is equipped with of cup jointing, two sides of adapter sleeve are equipped with the stop collar, be equipped with on the stop collar and be used for the fixed mounting with installation axle, the outside of adapter sleeve is equipped with the connecting block for with the blade disc fixed connection of lathe, be equipped with the connecting piece that is used for blade disc and connecting block to be connected on the blade disc.
As an improvement, the lower end of the mounting shaft is provided with a limiting groove.
As an improvement, the connecting piece is clamped in the limiting groove.
The utility model has the advantages that:
the utility model discloses simple structure, high durability and convenient use, after the lathe leaves the factory, lathe chuck's center and the upper end of blade disc are high, can be very fast accomplish the heart with connecting block and blade disc are fixed together, the adapter sleeve uses the stop collar of both sides to carry on spacing fixed, rather than the mode of using the direct fixation stop collar, can reduce the influence to installing the axle stress, guarantee the accuracy to the heart, and both sides all are equipped with the mounting, can offset stress each other, can guarantee that chuck center and installation axle center are on same straight line, guarantee drilling quality, original lathe tailstock is that there is the position to be injectd, influence the tailstock stroke, now use the tailstock that removes, can guarantee the stroke, thereby can carry out deep hole machining, the whole input cost of lathe is low, the later maintenance is few, can save the input cost.
