Description

Technical Field

[0001] This utility model relates to the field of diamond wire saw technology, specifically a diamond wire saw that is easy to tension. Background Technology

[0002] In the fields of high-precision processing of hard and brittle materials such as stone processing and semiconductor wafer cutting, the tension of diamond wire saws affects cutting accuracy and equipment stability. Traditional wire saw tensioning devices mostly use bolt and nut or spring structures, which are difficult to adjust and maintain stably. Bolt and nut tensioning requires repeated tightening of the nut, which is cumbersome and tension control depends on manual experience. It is easy to cause problems such as wire saw breakage due to over-tightening or cutting deviation due to over-loosening. Although spring tensioning devices can provide a certain degree of elasticity and buffering, the spring is prone to fatigue failure under long-term cutting vibration, resulting in tension decay and wire saw slippage, which affects cutting quality and efficiency. Existing tensioning devices lack an effective one-way locking mechanism. During the cutting process, the reverse force generated by the resistance of the material can easily loosen the tensioning components, causing tension fluctuations. This not only reduces cutting accuracy but also shortens the service life of the wire saw due to frequent loosening and re-tightening. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a diamond wire saw that is easy to tension. Through a one-way locking mechanism and a segmented adjustment design, the tension force can be controlled and quickly adjusted, thereby improving the stability of the cutting process and the service life of the wire saw.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a diamond wire saw that is easy to tension, comprising a wire saw frame, a connecting rod slidably connected to the inner wall of the wire saw frame, a first fixing clamp fixedly connected to the outer wall of the bottom of the connecting rod, an internally threaded cylinder fixedly connected to the inner wall of the wire saw frame, an adjusting rod threadedly connected to the inner wall of the internally threaded cylinder, and a tensioning device fixedly connected to the outer wall of the wire saw frame; the tensioning device includes a connecting device, a movable device rotatably connected to the outer wall of the connecting device, and a second fixing clamp fixedly connected to the outer wall of the bottom of the movable device;

[0007] Preferably, the connecting device includes a connecting block, the inner wall of which is slidably connected to a ratchet via a limiting groove, the outer wall of which is fixedly connected to an anti-detachment ring, the inner wall of which is rotatably connected to an adjusting screw, the outer wall of the top of the connecting block being fixedly connected to the outer wall of the wire saw frame, and the outer wall of the adjusting screw being rotatably connected to the inner wall of the connecting screw. By utilizing the one-way locking mechanism of the ratchet and pawl, the tension of the wire saw can be finely adjusted. Under the action of the torsion spring, the pawl engages with the teeth of the ratchet, effectively preventing the wire saw from loosening and avoiding the reciprocating loosening problem that is prone to occur in traditional tensioning devices.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-6 This utility model provides a technical solution: a diamond wire saw that is easy to tension, including a wire saw frame 1, a connecting rod 2 slidably connected to the inner wall of the wire saw frame 1, a first fixing clamp 6 fixedly connected to the outer wall of the bottom of the connecting rod 2, an internal threaded cylinder 4 fixedly connected to the inner wall of the wire saw frame 1, an adjusting rod 5 threadedly connected to the inner wall of the internal threaded cylinder 4, and a tensioning device 3 fixedly connected to the outer wall of the wire saw frame 1; the tensioning device 3 includes a connecting device 31, a movable device 32 rotatably connected to the outer wall of the connecting device 31, and a second fixing clamp 33 fixedly connected to the outer wall of the bottom of the movable device 32. First, the two ends of the wire saw are clamped and fixed by the first fixing clamp 6 and the second fixing clamp 33 respectively. Rotating the adjusting rod 5, the threaded engagement between its outer wall and the inner wall of the internal threaded cylinder 4 drives the connecting rod 2 to slide along the inner wall of the wire saw frame 1, thus initially adjusting the basic tension of the wire saw;

[0023] The connecting device 31 includes a connecting block 311. A ratchet 313 is slidably connected to the inner wall of the connecting block 311 through a limiting groove 312. An anti-detachment ring 314 is fixedly connected to the outer wall of the ratchet 313. An adjusting screw 315 is rotatably connected to the inner wall of the anti-detachment ring 314. The outer wall of the top of the connecting block 311 is fixedly connected to the outer wall of the wire saw frame 1. The outer wall of the adjusting rod 5 is rotatably connected to the inner wall of the connecting rod 2.

[0024] The movable device 32 includes a rotating rod 321, with a threaded hole 322 in its wall. A connecting shell 323 is fixedly connected to the outer wall of the top of the rotating rod 321, and a fixing rod 324 is fixedly connected to the inner wall of the connecting shell 323. A torsion spring 325 is sleeved on the outside of the fixing rod 324, and a pawl 326 is rotatably connected to the end of the fixing rod 324 away from the connecting shell 323. A limit rod 327 is fixedly connected to the inner wall of the connecting shell 323. The user drives the rotating rod 321 to rotate around the outer wall of the connecting block 311. Inside the connecting housing 323 at the top of the rotating rod 321, the pawl 326 is always engaged with the teeth of the ratchet 313 under the action of the torsion spring 325, forming a one-way transmission structure: when the rotating rod 321 rotates along the teeth of the ratchet 313, the pawl 326 passes over the ratchet 313. At this time, the rotating rod 321 further tensions the cutting line by pulling the second fixed clamp 33. At this time, the pawl 326 is blocked by the ratchet 313, making it difficult for the rotating rod 321 to return, thus ensuring the tension level and allowing the wire saw to maintain tension.

[0025] One end of the torsion spring 325 is fixedly connected to the inner wall of the connecting shell 323, and the other end of the torsion spring 325 is fixedly connected to the inner wall of the pawl 326. The outer wall of the rotating rod 321 is rotatably connected to the outer wall of the connecting block 311. The inner wall of the rotating rod 321 is threadedly connected to the outer wall of the adjusting screw 315 through the threaded hole 322. When the wire saw needs to be loosened, the adjusting screw 315 is rotated in the opposite direction, so that the adjusting screw 315 drives the ratchet 313 to move into the limiting groove 312 of the connecting block 311 until the ratchet 313 enters the limiting groove 312 and then disengages from the meshing range of the pawl 326. At this time, the pawl 326 loses its obstruction, and the rotating rod 321 can be freely rotated to loosen the wire saw to a degree that is easy to remove.

[0026] When using this diamond wire saw, first clamp and fix both ends of the wire saw with the first fixing clamp 6 and the second fixing clamp 33 respectively. Rotate the adjusting rod 5, and the threaded engagement between its outer wall and the inner wall of the inner threaded cylinder 4 will drive the connecting rod 2 to slide along the inner wall of the wire saw frame 1 to initially adjust the basic tension of the wire saw.

[0027] When the tensioning device 3 is working, the user drives the rotating rod 321 to rotate around the outer wall of the connecting block 311. Inside the connecting shell 323 at the top of the rotating rod 321, the pawl 326 is always engaged with the teeth of the ratchet 313 under the action of the torsion spring 325, forming a one-way transmission structure: when the rotating rod 321 rotates along the teeth of the ratchet 313, the pawl 326 passes over the ratchet 313. At this time, the rotating rod 321 further tensions the cutting line by pulling the second fixed clamp 33. At this time, the pawl 326 is blocked by the ratchet 313, making it difficult for the rotating rod 321 to return, thus ensuring that the tension is reached and the wire saw maintains tension. When the pawl 326 slides along the tooth surface of the ratchet 313, the elastic potential energy stored in the torsion spring 325 ensures that the pawl 326 is always engaged with the next tooth, preventing the wire saw from loosening.

[0028] When the wire saw needs to be loosened, rotate the adjusting screw 315 in the reverse direction. This causes the adjusting screw 315 to move the ratchet 313 into the limiting groove 312 of the connecting block 311 until the ratchet 313 enters the limiting groove 312 and disengages from the pawl 326. At this point, the pawl 326 is no longer obstructed, and the rotating rod 321 can be freely rotated to loosen the wire saw to a level that facilitates removal. After adjustment, rotate the adjusting screw 315 in the forward direction again to disengage the ratchet 313 from the limiting groove 312 and move it back to the pawl 326 engagement position. Due to the obstruction of the limiting rod 327, space is provided for the ratchet 313 to move, restoring its engagement with the pawl 326.

[0029] This wire saw achieves fine-tuning and stable maintenance of tension through a one-way locking mechanism of ratchet 313 and pawl 326, avoiding the reciprocating loosening problem of traditional tensioning devices 3. The cooperation between anti-detachment ring 314 and limit rod 327 ensures no axial deviation during rotation, thereby ensuring the stability of ratchet 313 and improving the reliability of the tensioning structure. Compared with traditional wire saws, its segmented tension adjustment improves operating efficiency and facilitates tensioning by personnel. The one-way locking mechanism effectively prevents the wire saw from slipping or breaking during cutting, extending the service life of the wire saw.
