Detailed description of the invention
The utility model is further illustrated below in conjunction with the drawings and specific embodiments.
Fig. 1 is the main view of internal screw thread quick tool setting device in this example；
Fig. 2 is the side view of internal screw thread quick tool setting device in this example；
Fig. 3 is that internal screw thread quick tool setting device carries out the schematic diagram to knife in this example.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combines and is specifically illustrating, and the utility model is further described.
Referring to Fig. 1 and 2, it illustrates the composed structures for the internal screw thread automatic tool setting device that this example provides.As seen from the figure,
The internal screw thread automatic tool setting device mainly includes mounting seat 1, guide rod 2, cylinder 3, cylinder mounting base 4, measuring head installation bottom
Plate 5, stop screw 6, measuring head 8.
Wherein, basic components of the mounting seat 1 as whole device, for carrying other building blocks.The mounting seat 1
Specific structure and lathe grinding wheel stand at the top of match, and guarantee enough intensity.The whole peace of the mounting seat 1 of such structure
At the top of lathe grinding wheel stand, top surface is as placement surface for disposing other building blocks.
Guide rod 2 is integrally provided on the placement surface of mounting seat 1, is oriented to for the movement to cylinder mounting base 4.
Two guide rods 2 are used in the present apparatus, it is symmetrical between two guide rods 2 to be installed on 1 left and right sides of mounting seat, to protect
Demonstrate,prove cylinder mounting base 4 mobile stabilization and reliability.
Cylinder mounting base 4 is the transmission parts in the present apparatus, is movably placed on guide rod 2.Specifically, this reality
Cylinder mounting base 4 is mounted on two guide rods 2 by linear bearing in example, and can be moved along guide rod 2.
Cylinder 3 is the power source in the present apparatus, is placed on the placement surface of mounting seat 1 relative to cylinder mounting base 4,
And it drives end to connect with cylinder mounting base 4, thus cylinder mounting base 4 can be driven to be moved along guide rod 2.
Stop screw 6 corresponds to the shift motion of cylinder mounting base 4, is mounted as a whole on 1 lower part of mounting seat, for gas
The shift motion of cylinder mounting base 4 is limited, to cooperate other components to run.
Measuring head mounting base 5 is mounted as a whole in cylinder mounting base 4, for disposing measuring head 8, to drive measuring head 8
It is mobile towards workpiece 7.In order to ensure reliability, the measuring head mounting base 5 is whole using rectangle structure in this example, and
Horizontal vertical is placed in cylinder mounting base 4, i.e., vertical with the moving direction of cylinder mounting base 4.The measuring head peace so disposed
Bottom plate 5 is filled, top is integrally stretched out outside mounting seat 1.
Measuring head 8 is mounted as a whole on the top of measuring head mounting base 5, and is tilted a certain angle.To guarantee device
Performance, the preferred LP2 inductance type measurement head of measuring head 8 in this example, when being placed in measuring head 5 top of mounting base, top
Diagonally downward, and between measuring head mounting base 5 it is in 30-45 ° of angle, is tested in order to cooperate with workpiece 7.
According to the internal screw thread quick tool setting device that above scheme is constituted, there is one using outer diameter face in nut design drawing
The initial angle of plane and screw thread has a corresponding fixed relationship, and the center by measuring this plane determines screw thread indirectly
Initial angle, to calculate processing starting point.
The present apparatus in specific application, can configure corresponding control device as needed as a result, Lai Shixian internal screw thread from
It moves to knife.
The control device specifically controls cylinder 3 and measuring head 8 in attachment device, and realization can be directed to any installation spiral shell
Mother automatically determines processing starting point, is not necessarily to manual confirmation, and processing non-cutting time is substantially reduced and reduces due to mistake
Rejected part caused by operation is greatly improved production efficiency and dimensional accuracy in this way, can larger reduction production cost.
Here the independent PLC of setting can be used to realize or using the controller on existing lathe come real in control device
Existing, concrete composition structure is the prior art for a person skilled in the art, be will not be repeated here herein.
For the internal screw thread quick tool setting device of above-mentioned structure, illustrates that it is directed to the nut of any installation below, carry out
Automatically determine the process of processing starting point (referring to Fig. 3).
When nut installs, control device carries out aim at tool operation, and control cylinder 3 first drives cylinder mounting base 4, by gas
Cylinder mounting base 4 drives measuring head mounting base 5 to move downward along guide rod 2, when cylinder mounting base 4 and stop screw 6 contact
When, the side head of measuring head 8 just mills the top of flat position in workpiece 7.
At this moment the main shaft (C axis) of clamping workpiece 7 does clockwise movement by Serve Motor Control, until the side of measuring head 8
The left side that head and workpiece 7 mill flat position contacts and acquires current C shaft position A, then C axis counterclockwise movement, until measuring head 8
Side head and workpiece 7 mill the right of flat position and contact and acquire current C shaft position B, by formula (A+B)/2 calculate C axis A,
The median of B location, the corresponding C axial coordinate of this median have fixed relationship with the initial angle of screw thread always；Then pass through
Formula scales calculate C axis and Z axis (axis and C axis moving interpolation stroke threaded line that Z axis is parallel to 7 axis of workpiece) plus
Work starting point.
After measurement, cylinder 3 drives cylinder mounting base 4, and cylinder mounting base 4 drives measuring head mounting base 5 along leading
Moved up to bar 2 it is upper, make measuring head 8 far from workpiece reach home, so far automatic measurement terminates.
Basic principles, main features, and advantages of the present invention has been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
