In general, the saw is one of the tools widely used in the industrial field from the structure in which the sharp sawtooth is engraved on one edge of the steel sheet so as to be able to cut wood, metal, stone, and plastic. Furthermore, saws are divided into various kinds according to the materials to be processed and machined parts, but the saw blades are separately produced and used according to the kinds thereof, and they are mainly used for wood processing in the woodworking field.

Here, the saw blade is machined so as to have teeth of various sizes and intervals having opposite inclination angles at one end thereof. Since the saw blade is subjected to various machining processes such as sawtooth formation, various types of saw blades can be smoothly A saw blade machining device configured to be machined can be used.

As a conventional art disclosed in relation to the saw blade machining apparatus described above, in the Korean Utility Model Publication No. 1802 (Mar. 03, 1994), the front and rear working plates are fixed to a moving body, A top fixing device is provided on the left and right operating plates sandwiched between the engaging grooves of the front and rear operating plates, the driving shaft of the motor is fitted to the supporting bracket fixed to the front of the operating plate, one cam of the driving shaft is brought into contact with the bearing of the fixing frame, The cam is brought into contact with the bearing on the bottom of the operating element, and the upper portion thereof is brought into contact with the pushing rod which is engaged with the operating spring so that when the rotating body rotates, the pushing rod moves and pushes the guiding piece, A saw blade for manufacturing an excellent product by machining a saw blade according to a constant movement Factory values are known.

That is, when the abrasive member 120 of the grinding unit 100 is abraded toward the workpiece positioned on the jig member 220, the abrasion detecting unit 300 detects the abrasion amount of the abrasive member 120, .

The abrasion detecting unit 300 may be constructed using an infrared ray sensor or the like and may be constructed using a digital infrared ray sensor to effectively transmit a measurement signal to the controller 400. [

The abrasion detecting unit 300 senses the abrasion amount of the abrasive member 120 and transmits a detection signal to the control unit 400 so that the abrasive member 120 can be always detected. 120 may be periodically detected.

The abrasion detecting unit 300 periodically senses the abrasion amount of the abrasive member 120 in accordance with the grinding process of the workpiece from the grinding unit 100. This reduces the amount of power consumed, It is preferable to reduce errors.

The wear detection unit 300 transmits a detection signal to the controller 400 at a predetermined number of times from the polishing process of the workpiece by the polishing member 120. The control unit 400 ) To transmit the detection signal.

For example, when the control unit 400 sets the cycle of the detection signal of the abrasion detecting unit 300 to three cycles, the abrasive member 120 of the grinding unit 100 finishes polishing the three workpieces The abrasion detecting unit 300 senses the abrasion amount of the abrasive member 120 and transmits a signal to the controller 400.

In the case where a signal is transmitted with less than three times of polishing, the system error phenomenon or power consumption due to too frequent signal transmission is large. In the case where the signal is transmitted after the number of times of polishing exceeds 5, the processing accuracy is lowered.

As shown in FIG. 2, the control unit 400 applies a control signal to move the grinding unit 100 in accordance with a signal input from the wear detection unit 300.

Although not shown in the drawings, the controller 400 includes a controller that can operate the respective components of the present invention. The controller 400 receives the control signal from the controller, and controls the grinding unit 100 and the clamp unit 200 in response to the control signal.

If the amount of wear input from the wear detection unit 300 is equal to or greater than the predetermined dimension, the control unit 400 controls the front and rear conveying means 140 of the grinding unit 100 such that the amount of wear of the abrasive member 120 And applies a control signal that moves toward the clamp unit (200).

For example, the control unit 400 sets and stores a reference value for a wear amount of the abrasive member 120, and the front and rear conveying means 140 of the grinding unit 100 may compensate the clamp unit 200 And controls the movement of the abrasive member 120 according to the detection signal from the abrasion detection unit 300 according to the movement of the abrasive member 120 and the movement of the abrasive member 120 according to the forward /

As described above, when the control unit 400 is configured, it is possible to always maintain a normal grinding state by controlling the grinding member 120 from the front and rear conveying means 140 of the grinding unit 100 to compensate the movement thereof.

Next, the operating relationship of the saw blade automatic polishing machine having the wear compensation function according to the preferred embodiment of the present invention will be described.

The workpiece is attached and fixed on the jig member 220 of the clamp unit 200 after applying power to the grinding unit 100 and the clamp unit 200 in a state in which each drive configuration is operable, (100) and the clamp unit (200).

At this time, the clamp unit 200 selects one of a linear machining process and a curved machining process according to the workpiece to be fixed on the jig member 220, and sets the machining mode by the lift-and-unlocking means 250.

Here, as shown in FIG. 10A, since the elevation guiding means 230 is set to the locked state by using the elevation locking means 250, the straight type movement can be performed only by the left and right conveying means 240 And the workpiece fixed on the jig member 220 linearly moves left and right in a state in which the abrasive member 120 of the grinding unit 100 is in contact with the workpiece.

On the other hand, as shown in FIG. 10 (b), since the elevation guiding means 230 is set in the unlocked state from the elevation locking means 250, the elevation frame 233 is lowered by its own weight When the guide plate 263 of the guide means 260 contacts the bearing member 261 and moves linearly by the left and right conveying means 240 along the guide surface 264 of the guide plate 263, 230 are moved up and down so that the workpiece fixed on the jig member 220 moves in a curved shape in left and right and up and down directions in contact with the abrasive member 120 of the grinding unit 100. Thus, the workpiece is curved.

The grinding unit 100 is driven by the driving force of the rotating means 130 so that the polishing member 120 rotates and advances from the forward and rearward conveying means 140 toward the clamp unit 200, 220, the abrading member 120 is brought into contact with the cutting surface of the workpiece.

When the abrasive member 120 of the grinding unit 100 abrades the workpiece placed on the jig member 220 of the clamp unit 200 while the abrasive member 120 is abraded, And transmits a signal to the control unit 400. [0033] FIG.

The control unit 400 applies a control signal to the front and rear conveying units 140 of the grinding unit 100 according to the amount of wear input from the wear detection unit 300, 200 to the jig member 220 so as to maintain continuous precision processing.

That is, according to the saw blade automatic grinding apparatus having the wear compensation function according to the present invention configured as described above, since the grinding operation for the cutting surface of the saw blade is automated, it is possible to reduce the labor cost, It is possible to greatly improve the productivity. Further, since the amount of wear of the abrasive member touching the workpiece is sensed and controlled to compensate movement, it is possible to improve the quality of the product and produce the good product by increasing the precision of the product while increasing the numerical accuracy by the processing device.

While the preferred embodiments of the saw blade automatic grinding machine having the wear compensation function according to the present invention have been described above, the present invention is not limited thereto, and various modifications may be made within the scope of the claims, And it is also within the scope of the present invention.
