Abstract
The utility model discloses the technique relates to a special fixture, specifically is used for automatic boring grab of economical numerical control lathe for one kind. The utility model provides an economical numerical control lathe low because of the unable manual drilling efficiency of automated programming, the poor problem of precision, be used for the automatic boring grab of economical quadruplex position numerical control lathe, this set anchor clamps comprise clamp cover seat and taper hole cover, it installs on the numerical control lathe knife rest to press from both sides the cover seat, and compress tightly on the knife rest with the bolt, the taper hole cover is in the same place through welded connection with clamp cover seat, the taper hole cover is the taper hole that has morse taper, taper hole cover afterbody has the U -shaped groove, the U -shaped groove is used for the tang of solid fixed cone handle drill bit, prevent that the drill bit from rotating because of the atress, taper hole cover afterbody U -shaped groove is link up, be favorable to taking out the drill bit, the taper hole is sheathe in and is processed out a plane A, available percentage table alignment boring grab, make taper hole axis and main shaft axis coincidence, taper hole cover left side excircle is used for the alignment taper hole and the alignment of shafts, make taper hole and lathe main shaft axle concentric. The utility model discloses simple structure can be applied to all economical leading knife rest numerical control lathe's automatic drill spot facing work.
Description
Technical field
This utility model belongs to mechanical manufacturing field, relates to a kind of fixture utilizing low-cost type CNC lathe to carry out automatic drilling.
Background technology
Low-cost type CNC lathe is developed by engine lathe, is generally knife-carrier before four stations, and operator scheme is controlled feeding by digital control system, automatically processes.Low-cost type CNC lathe is holed, has no difference with holing on engine lathe, still rely on installation drill bit on tail stock, carry out Drilling operation by rotating tailstock handwheel.Because tailstock does not have auto-feed function, relying on manual length feed, not only the labor intensity of operator is big, and production efficiency is low, and the degree of depth in the hole come outbreak out also is not easily controlled.
As processed the bulk article of class with holes with numerically controlled lathe, still need to pay substantial amounts of physical work, and size can not well control, also do not manifest the feature that numerically controlled lathe automaticity is high.
Summary of the invention
This utility model technology in order to for and solve the problems referred to above, this utility model is by changing installation way, utilizing is arranged on knife rest by drill bit by fixture, utilizes the automatic displacement of knife rest and the function of supporting plate energy automatic traction knife rest auto-feed to remove to realize automatic drilling, reduces cost of labor.Utilize numerically controlled lathe to carry out hole type parts automated production by boring grab, improve production efficiency, reduce production cost, it is ensured that product quality.
For achieving the above object, the present invention designs a kind of special automatic drilling fixture on low-cost type CNC lathe, including:
Fixture is made up of chuck seat and taper hole set, chuck seat is arranged on Tool-rest of Numerical Control Lathe, and with bolt presses on knife rest, taper hole set and chuck seat are by being welded together, taper hole set is the taper hole with Morse's taper, taper hole set afterbody has individual U-lag, U-lag is used for fixing the tang of taper-shank drill, prevent drill bit because of Forced rotation, taper hole set afterbody U-lag is through, be conducive to taking out drill bit, taper hole puts and processes a plane A, available dial gauge centering boring grab, taper hole axis is made to overlap with main-shaft axis, taper hole set left side cylindrical is used for centering taper hole and the alignment of shafts, make taper hole and machine tool chief axis axle concentric.
The effect that this utility model obtains:
1, simple in construction, easy for installation, clamping is reliable, and positioning precision is high.
2, this new technique is widely portable to the processing of low-cost type CNC lathe automatic drilling.
3, fixture is easy to adjust, is applicable to the Drilling operation of 2,3, No. 4 taper-shank drills of Mohs.
