Problems solved by technology

The hard protection uses the collision torque to judge, and the detection accuracy of the torque is not very high, which will lead to the phenomenon that no alarm will be issued even if the collision force is large

Embodiment Construction

[0009] Depend on figure 1 As we know, the spring floating electric spindle protection seat includes a connecting column 1, a spindle mounting plate 2, a motor mounting plate 3, a spring 4, a motor 5 and an inductive switch 6, and the spring 4 connects the two spindle mounting plates 2 and the motor mounting plate 3. Expand, lock and fix by elastic force, the motor 5 is installed on the motor mounting plate 3, and the whole machine head is mounted on the machine tool through the spindle mounting plate 2; the signal detection of the spindle is detected by the inductive switch 6.

[0010] Depend on figure 2 It is known that it is a schematic diagram of the structure of the tool head 7 of the machine tool spindle after the offset occurs. When the force of the machine tool touching the workpiece is greater than the force of safe processing or the cutting force is too large and exceeds the positioning force of 4 springs and 1 connecting column 1, the tool will be pushed to its ori...

Abstract

The invention discloses a spring floating type electric main shaft protection seat, which comprises a connection column (1), a main shaft mounting plate (2), a motor mounting plate (3), a spring (4), a motor (5), an electric induction switch (6) and a main shaft cutter head (7), and is characterized in that the electric induction switch (6) detects a working signal of the cutter head (7); the main shaft cutter head (7) is stressed to laterally move to drive the motor mounting plate (3) and the electric induction switch (6) to deviate; and furthermore, a signal sending instruction cuts off power, and a machine tool stops working. By the spring floating type electric main shaft protection seat, when force of the machine tool touching a workpiece is greater than safety machining stress, the connection column and the motor mounting plate laterally move because the main shaft cutter head is stressed, and the electric induction switch deviates up and down; and an induction signal is interrupted, so that a machine tool main shaft can be protected.

Description

technical field [0001] The invention belongs to the deburring equipment of special-shaped aluminum castings such as engines, the fine processing equipment of hardware parts and the electric spindle of welding equipment or the mounting seat of welding gun. It is an automatic machine tool suitable for micro-processing. The lateral force on the spindle of this series of machine tools is not very large, such as deburring machine tools, automatic mold lettering, line chamfering machine tools, mold special-shaped surface polishing machine tools, automatic welding machine tools, etc. Background technique [0002] The main shafts of some existing precision machining machine tools are mostly protected by hard contact (it means that whether to take protective measures is judged by the torque of the machine tool head after it hits the workpiece). Due to the complex internal structure of the spindle and motor of these fine machining machine tools, the precision requirements are very hig...
