Abstract
The invention provides a device for detecting the terminal position of a tool changing arm of a machining center, wherein a proximity switch is arranged on a tool changer spindle box through a switch connecting support and is positioned above the terminal position of the tool changing arm; metal induction heads are symmetrically arranged on the upper planes at the two ends of the tool changing arm; when the tool changing arm is located at the terminal position, the metal induction head is just located below the proximity switch, a position signal induced by the proximity switch is fed back to a numerical control system of the equipment, and the tool changing arm is the correct position of a tool changing completion terminal at the moment; and if the inductive switch and the inductive block are not aligned, other actions are completely terminated when the numerical control system sends an interlocking command. According to the invention, the position sensing device is arranged at the terminal position of the tool changing arm, and the position signal sensed by the proximity switch is fed back to the numerical control system of the equipment, so that the indication is the correct position of the tool changing completion terminal, the imagination that the tool changing arm can collide with the spindle box is completely prevented, the operation safety of the tool changing arm is ensured, and the equipment fault is avoided.
Description
Technical Field
The invention belongs to the field of final mechanical position detection of tool changing arms of cam type tool changing mechanisms of various vertical and horizontal machining centers, and particularly relates to a device for sensing and detecting the terminal position of the tool changing arm of a machining center.
Background
At present, the manufacturing industry in China is rapidly developed, various vertical and horizontal machining centers are continuously filled in every corner of the machining field, the tool changing faults of a tool magazine are 80% of the faults of the machining centers, and a motor drives a set of divider and a set of cam to rotate and displace in an equal division mode after rotation, so that the tool changing action of a tool changing arm is realized. However, all position detection in the middle, various imported or domestic tool magazines, the same or different, is to detect the tool changing position of the tool arm by a chain wheel device in the middle link, if any link goes wrong, for example: the chain breaks, the tool changing arm is connected and skids, and the like, although the middle detection switch is in the normal position, the final stop position of the tool changing arm after the switch deviates, the system can give a next processing instruction, and the spindle box and the tool changing arm collide to cause equipment accidents.
Disclosure of Invention
The invention provides a device for detecting the position of a terminal of a tool changing arm of a machining center, which aims to prevent equipment accidents caused by the fact that the tool changing arm collides with a spindle box.
Therefore, the technical scheme of the invention is as follows: machining center tool change arm terminal position response detection device, its characterized in that: a switch connecting support is arranged on the tool magazine spindle box, a proximity switch is arranged on the switch connecting support, and the proximity switch is positioned above the terminal position of the tool changing arm; metal induction heads are symmetrically arranged on the upper planes at the two ends of the tool changing arm; when the tool changing arm is located at the terminal position, the metal induction head is just located below the proximity switch, a position signal induced by the proximity switch is fed back to a numerical control system of the equipment, and the tool changing arm is the correct position of a tool changing completion terminal at the moment; and if the inductive switch and the inductive block are not aligned, other actions are completely terminated when the numerical control system sends an interlocking command.
The technical scheme is further limited as follows: the metal induction head is a metal screw, a threaded hole is formed in the cutter changing arm, and the metal screw is directly in threaded connection with the threaded hole; the structure of the induction head is simple and easy to implement and convenient to install.
The invention has the beneficial effects that: according to the invention, the position sensing device is arranged at the terminal position of the tool changing arm, and the position signal sensed by the proximity switch is fed back to the numerical control system of the equipment, so that the indication is the correct position of the tool changing completion terminal, the imagination that the tool changing arm can collide with the spindle box is completely prevented, the operation safety of the tool changing arm is ensured, and the equipment fault is avoided.
Drawings
Fig. 1 is a schematic structural view of the present invention.
Fig. 2 is a schematic view of an improved structure of the tool changing arm in the invention.
Detailed Description
The invention is further described below with reference to the accompanying drawings.
As shown in fig. 1 and 2, in the device for detecting the end position of the tool changing arm in the machining center, a switch connecting support 2 is mounted on a tool magazine spindle box 1 (through screws), a proximity switch 3 is mounted on the switch connecting support 2, and the proximity switch 3 is located above the end position of the tool changing arm 6; metal induction heads 5 are symmetrically arranged on the upper planes of the two ends of the tool changing arm 6 from left to right; when the tool changing arm 6 is located at the terminal position, the metal induction head 5 is located under the proximity switch (the tool changing arm 6 rotates 180 degrees, the tool changing arm 6 reaches the terminal position, the other metal induction head 5 is located under the proximity switch 3), the position signal sensed by the proximity switch is fed back to the numerical control system of the equipment, and the tool changing arm is the correct position of the tool changing finishing terminal; if the inductive switch and the inductive block are not aligned, other actions are completely terminated when the numerical control system sends an interlocking instruction, so that the running safety of the equipment is ensured.
As can be seen from fig. 1 and 2, the metal inductive head 5 is a metal screw, a threaded hole 7 is arranged on the tool changing arm 6, and the metal screw is directly connected to the threaded hole in a threaded manner; the structure of the induction head is simple and easy to implement and convenient to install.
The above description of the embodiments is the best mode of the invention; on the basis of the conception of the present invention, simple replacement and combination of technical features by those skilled in the art should fall into the scope of the present invention.
