Technical Field
[0001] This utility model relates to the field of saw blade processing technology, and in particular to a chamfering positioning device for a blanking saw. Background Technology
[0002] Commonly used sawing machines include circular saws, band saws, bow saws, and friction saws. Circular saws use circular saw blades; band saws come in vertical, horizontal, and tilting types; bow saws are suitable for small batches of bar stock with a diameter of 100mm or less; friction saws are mainly used for cutting steel, including tungsten or aluminum-containing steel, nickel-chromium steel, and chromium-silicon steel. They provide accurate cutting lengths, smooth blank ends, and good perpendicularity, making them extremely widely used. Various steels and non-ferrous metals can be sawed at room temperature, especially in precision forging processes. The disadvantages of sawing are lower productivity and higher saw blade wear.
[0003] In related technologies, after prolonged use, the saw blade of a cutting saw is prone to damage. Continued use will result in uneven workpiece ends, requiring the use of a chamfering device to remove burrs from the saw blade. However, some existing positioning components cannot effectively tighten the saw blade when fixing it, causing the saw blade to wobble during chamfering and grinding, thus affecting the chamfering effect.
[0004] Therefore, it is necessary to provide a chamfering positioning device for a blanking saw to solve the above-mentioned technical problems. Utility Model Content

The T-shaped sliders are threadedly connected to a lead screw, whose two ends are respectively movably connected to both sides of the U-shaped base. One end of the lead screw passes through one side of the U-shaped base, and the end of the lead screw is fixedly connected to the center of the turntable. The T-shaped slider is fixedly connected to a square tube, and a connecting block is fixedly connected to the upper side of the square tube. The connecting block has symmetrical through slots. The two ends of the square frame are slidably connected to the corresponding through slots. An S-type tension / compression sensor, model LFS-02, is fixedly connected to one side of the connecting block.
[0009] Preferably, the clamping assembly includes two lead screw grooves, which are respectively fixedly connected to the upper side of the U-shaped base. Two pairs of sliders are respectively provided in each of the two lead screw grooves. The inner ends of the two lead screw grooves are respectively movably connected to one end of a corresponding bidirectional lead screw. Each of the two bidirectional lead screws has two sections of threads with opposite directions. The two bidirectional lead screws are respectively threadedly connected to a corresponding pair of sliders. One end of each of the two bidirectional lead screws passes through one side of the corresponding lead screw groove. The ends of the two bidirectional lead screws are respectively fixedly connected to the center of a corresponding knob.

[0012] Compared with related technologies, the beneficial effects of this utility model are:
[0013] 1. Place the saw blade between the two guide rods, inserting the two rods into the round holes at both ends of the saw blade.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0028] A chamfering positioning device for a cutting saw includes a U-shaped base, and further includes a pulling component 1, a clamping component 3, and a control and display module 5. The pulling component 1 for detecting the tension of the saw blade 2 is provided above the U-shaped base 4, and the clamping component 3 for fixing the saw blade 2 is provided above the U-shaped base 4.
[0029] The traction assembly 1 includes two linear guide rails 12, which are respectively fixedly connected to the U-shaped base 4. The two linear guide rails 12 are respectively slidably connected to corresponding ball bearing sliders 17. The two ball bearing sliders 17 are respectively fixedly connected to T-shaped sliders 16. The T-shaped sliders 16 are threadedly connected to a lead screw 110. The two ends of the lead screw 110 are respectively movably connected to both sides of the U-shaped base 4. One end of the lead screw 110 passes through one side of the U-shaped base 4. At the center of the fixed connection turntable 11, the T-shaped slider 16 is fixedly connected to the square tube 18, and the upper side of the square tube 18 is fixedly connected to the connecting block 14. The connecting block 14 is provided with symmetrical through slots 19. The two ends of the square frame 13 are slidably connected to the corresponding through slots 19. An S-type tension-compression sensor 15 is fixedly connected to one side of the inner wall of the square frame 13. The model of the S-type tension-compression sensor 15 is LFS-02. One end of the S-type tension-compression sensor 15 is fixedly connected to one side of the connecting block 14.
[0030] The clamping assembly 3 includes two lead screw grooves 35, which are fixedly connected to the upper side of the U-shaped base 4. Two pairs of sliders 32 are respectively provided within each of the two lead screw grooves 35. One end of a corresponding bidirectional lead screw 33 is movably connected to the inner ends of each of the two lead screw grooves 35. Each of the two bidirectional lead screws 33 has two sections of threads with opposite directions. Each of the two bidirectional lead screws 33 is threadedly connected to a corresponding pair of sliders 32. One end of each of the two bidirectional lead screws 33 passes through one side of the corresponding lead screw groove 35. The ends of each of the two bidirectional lead screws 33 are fixedly connected to the center of a corresponding knob 34. Guide rods 31 are fixedly connected to the opposite sides of the corresponding pair of sliders 32. The two guide rods 31 pass through the square tube 18.
[0031] One side of the square frame 13 is fixedly connected to a protrusion 23, and the other protrusion 23 is fixedly connected to the upper side of the lead screw groove 35. The two protrusions 23 are respectively fixedly connected to the corresponding insert rods 22 on one side.
[0032] The control and display module 5 is fixedly connected to the upper side of the U-shaped base 4.
[0033] The control and display module 5 is electrically connected to the S-type tension / compression sensor 15.
[0034] Working principle: First, place the saw blade 2 between the two guide rods 31, so that the two insertion rods 22 are inserted into the round holes 21 at both ends of the saw blade 2. Then, connect the power supply of the control and display module 5 to the external power supply. The display of the control and display module 5 is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail. Then, rotate the turntable 11. The turntable 11 drives the lead screw 110 to rotate. The lead screw 110 drives the T-shaped slider 16 to slide. The T-shaped slider 16 drives the ball slider 17 to slide along the linear guide rail 12. At the same time, the T-shaped slider 16 drives the connecting block 14 to move through the square tube 18. The connecting block 14 drives the square tube 14 to move through the through slot 19. As frame 13 moves, the square frame 13 applies a pulling force to the saw blade 2 through the insert rod 22 and the round hole 21. Under the action of the reaction force, the square frame 13 applies a pressure to the S-type tension-compression sensor 15. The force on the saw blade 2 and the S-type tension-compression sensor 15 are equal. During the pulling process, the S-type tension-compression sensor 15 feeds back the pressure signal to the control chip of the control and display module 5, so that the display screen of the control and display module 5 displays the value. When the preset value is reached, the rotating disk 11 stops rotating. At this time, the saw blade 2 can be tightened. The setting of the S-type tension-compression sensor 15 and the control and display module 5 allows the observation of the tension value on the saw blade 2, effectively preventing the saw blade 2 from being broken.
[0035] Then turn the two knobs 34. The two knobs 34 will drive the two-way lead screws 33 to rotate. The two-way lead screws 33 will drive the corresponding pair of sliders 32 to slide, so that the corresponding pair of sliders 32 will drive the guide rods 31 to clamp the saw blade 2. At this time, stop turning the knobs 34 to fix the saw blade 2, and then start the subsequent operation.
[0036] Beneficial effects: The saw blade 2 is placed between two guide rods 31, and the two insert rods 22 are respectively inserted into the round holes 21 provided at both ends of the saw blade 2. Through the pulling component 1, the S-type tension and compression sensor 15 feeds back the pressure signal to the control chip of the control and display module 5, so that the display screen of the control and display module 5 displays the value. When the preset value is reached, the saw blade 2 can be tightened. The setting of the S-type tension and compression sensor 15 and the control and display module 5 can observe the tension value of the saw blade 2, effectively preventing the saw blade 2 from being broken. Through the clamping component 3, the guide rods 31 clamp and fix the saw blade 2, and then the subsequent operation begins.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
