the linear driving module 1 includes a movable block 1.1, a mounting base 1.2, a servo motor (not shown), and a linear module (not shown), and the linear driving module mainly functions to provide high-precision linear motion for the push rod 2, and the linear module may be a screw-nut mechanism, a rack-and-pinion mechanism, or other linear motion mechanisms. The mounting base 1.2 is fixedly connected with the main body of the linear driving module 1, the movable block 1.1 is connected with the mounting base 1.2 through the dovetail groove 1.3 (one of the movable block 1.1 and the mounting base 1.2 is provided with the dovetail groove, and the other is provided with a bulge matched with the dovetail groove in shape), one end of the push rod 2 is hinged with the movable block 1.1, and the extending direction of the dovetail groove 1.3 is parallel to the rotating axis (the hinged axis of the push rod 2). Through setting up dovetail 1.3, can adjust the relative position of movable block 1.1 and installation base 1.2 (need utilize the fastener to fix the relative position after adjusting the relative position), articulate like this and can be suitable for the band saw blade of different width in push rod 2 of movable block 1.1, ensure that the tooth piece 3 that pushes away can accurately the butt in the root of tooth support 4.
Still including grating chi 6, grating chi 6 is used for the position of real-time recording linear drive module 1 (for the position of taking notes movable block 1.1 and installation base 1.2), utilizes the position of the linear drive module 1 of location that grating chi can be accurate, and then accurate control pushes away the accurate motion of tooth piece 3, ensures that the removal of the back of the band saw blade is accurate controllable.
In order to ensure the feeding precision of the band saw blade, the device adopts a position recording method, a proper main control chip is selected, the servo motor drives the tooth pushing piece 3 to push the back material 7 of the band saw blade in a position control mode, and the real-time position of the tooth pushing piece is fed back to the main control chip through the external grating ruler 6, so that the precise control of a full closed loop is realized. The main control chip is communicated with the human-computer interface through RS485, and the real-time position of the pushing tooth piece 3 can be displayed in the human-computer interface. The system control flow chart is shown in fig. 5. In the whole saw band feeding process, the main control chip continuously receives the displacement feedback signals of the grating ruler, so that the displacement can be adjusted in real time in the feeding process to realize accurate feeding of the saw band.
As shown in FIG. 4, the method for feeding the back material of the band saw blade by adopting the device mainly comprises the following steps:
1) the tooth pushing plate 3 is in a waiting position (on fig. 4), that is, the tooth pushing plate 3 is located between the tooth holder to be welded and the next tooth holder, and this position is marked as a waiting position X1;
2) the linear driving module 1 drives the tooth pushing sheet 3 to move along a straight line, the tooth pushing sheet 3 pushes the tooth to be welded to be supported to a welding position (in fig. 4), and the grating ruler records the current position X2;
3) the linear driving module 1 drives the pushing tooth piece 3 to move along a straight line, the pushing tooth piece 3 moves backwards for a certain distance to a welding waiting position (shown in fig. 4), the pushing tooth piece 3 is still positioned between a tooth support to be welded and the next tooth support, and the position is marked as X3; at this time, whether the position of the tooth support to be welded is correct is judged, and if the position is correct, a welding mechanism (not shown) executes the welding operation of the tooth support to be welded; if the position of the tooth support to be welded exceeds the correct position, the back material of the band saw blade is retreated for a certain distance and then corrected, and the linear driving module drives the tooth pushing piece to retreat to the welding waiting position after correction;
4) the linear driving module 1 drives the tooth pushing sheet 3 to move along a straight line, and the tooth pushing sheet 3 moves backwards to cross (the push rod 2 rotates upwards slightly) the next tooth support to a waiting position;
and (5) continuously repeating the steps 1) to 4) to finish the automatic welding of the whole band saw blade.
Because the welding position is always unchanged, even if the tooth pitches of the back materials of the band saw blades are different, the grating ruler only records the position of the push rod, so that the change of the welding position caused by the different tooth pitches is not needed to be worried about, and the advancing distance L1 of the push rod from the waiting position to the welding position is X2-X1; and the distance L2 from the position of the pushing blade 3 at the time of welding to the waiting position of the next welding is X3-X1. Therefore, the method of the invention can be completely suitable for welding the variable-pitch band saw blade, and ensures the accuracy of the welding position. Through setting up the welding wait position that pushes away the tooth piece, can finely tune the correction in the position of taking the saw blade backing material fast on the one hand, on the other hand pushes away the tooth piece and can not take place to interfere with welding mechanism when guaranteeing the welding.
