Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, and in particular to a tension stabilizing device for single-wire cutting equipment. Background Technology

[0002] Single-wire cutting equipment uses a high-speed metal cutting wire to cut hard and brittle materials. When the cutting wire contacts the workpiece, it must maintain a constant tension to ensure the straightness of the cutting trajectory and the processing accuracy. During long-term high-load pulling and friction, the cutting wire will undergo plastic deformation, resulting in elongation and decreased tension. Insufficient tension will cause the cutting wire to bend in an arc shape inside the workpiece. Severe tension fluctuations will directly cause ripples on the cut surface or even cause wire breakage.

[0003] Existing single-wire cutting equipment often uses a motor to directly drive the tension wheel for wire winding and unwinding adjustment. After the motor stops outputting torque, it cannot resist the reverse tension generated by the cutting wire. The elastic restoring force of the cutting wire will cause the tension wheel and motor shaft to rotate in the opposite direction, resulting in the tension value after adjustment not being able to maintain stability. The transmission structure, which lacks mechanical self-locking function, makes it difficult to achieve dynamic balance control of cutting tension. At the same time, the existing tension wheel and shaft are mostly connected by interference fit or multiple bolts. When replacing a tension wheel with severe surface wear, the operator needs to disassemble a large number of parts. The cumbersome disassembly and assembly process increases the downtime of the equipment for maintenance.

[0004] Therefore, this utility model proposes a tension stabilizing device for single-wire cutting equipment to address the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems existing in the tension stabilization device of single-wire cutting equipment, such as the lack of self-locking function for cutting tension, easy fluctuation of tension value due to reverse tension of cutting wire after the motor stops, and cumbersome disassembly and replacement process of tension wheel with low maintenance efficiency, this utility model aims to provide a tension stabilization device for single-wire cutting equipment with improved structure that can effectively solve the above problems.

[0006] This utility model provides a tension stabilizing device for a single-wire cutting equipment, including: a frame, a cutting device fixedly connected inside the frame, an inspection door hinged to the front surface of the frame, and a U-shaped block fixedly connected to the bottom of the frame; it also includes a tension stabilizing mechanism disposed inside the U-shaped block.

[0007] The tension stabilizing mechanism includes a motor fixedly connected to the bottom of the inner wall of the U-shaped block, a worm gear fixedly connected to the output end of the motor, a rotating shaft rotatably connected to the inner wall of the U-shaped block, a worm wheel fixedly connected to one end of the rotating shaft, the worm wheel meshing with the worm gear, a tensioning wheel detachably connected to the outer wall of the rotating shaft via a quick-release mechanism, and multiple guide wheels rotatably connected to the inner side wall of the U-shaped block. The quick-release mechanism includes a limiting groove formed on the outer wall of the rotating shaft and a limiting block fixedly connected to the inner side wall of the tensioning wheel, with the limiting block slidably connected to the limiting groove.

[0008] Furthermore, the motor drives the rotating shaft and tension wheel to rotate through the cooperation of the worm and worm wheel. The quick release mechanism restricts the relative rotation of the tension wheel and the rotating shaft through the cooperation of the limiting groove and the limiting block. The guide wheels are distributed along the cutting path of the cutting device to guide the cutting line.

[0009] Preferably, a fixing block is slidably connected inside the limiting groove, and a bolt is threaded through the top of the fixing block. The end of the bolt abuts against the inner wall of the limiting groove, and the fixing block is located outside the limiting block to axially limit the tensioning wheel.

[0010] Preferably, a fixing groove is provided on one side of the outer wall of the U-shaped block, and a fixing plate is embedded inside the fixing groove. The end of the rotating shaft away from the worm gear is rotatably connected to the side wall of the fixing plate.

[0011] Preferably, each of the four corners of the outer wall of the fixing plate is threaded with two bolts, the bolts penetrating the fixing plate and threaded into the inside of the side wall of the U-shaped block.

[0012] Preferably, the outer wall of the guide wheel is provided with an annular groove for limiting the displacement of the cutting line, and multiple guide wheels are distributed around the tension wheel along the cutting device's cutting path.

[0013] Preferably, the U-shaped block has a hollow structure, and the U-shaped block is fixedly installed at the center of the bottom surface inside the frame, while the motor is horizontally installed on the inner bottom wall of the U-shaped block.

[0016] Preferably, the worm gear axis is perpendicular to the shaft axis, and the shaft passes through the central through hole of the tensioner.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model solves the problem in the prior art where the tension adjustment mechanism for cutting wire is prone to reverse rotation due to the reverse tension of the cutting wire after the motor stops by setting a transmission method in which the motor drives the worm gear to rotate the worm wheel and the shaft. By utilizing the mechanical self-locking characteristics of the worm gear mechanism, it achieves the effect of precise tension adjustment and maintaining dynamic balance and stable control after adjustment, effectively preventing the cutting wire from loosening and improving cutting accuracy.

[0019] 2. This utility model solves the problem of cumbersome disassembly and replacement steps and low maintenance efficiency of the tension wheel as a vulnerable part after wear by setting a quick-release mechanism including a limiting groove, a limiting block and a fixing block between the rotating shaft and the tension wheel, and cooperating with the embedded fixing plate to support the end of the rotating shaft. It achieves the effect of quickly completing the axial locking and anti-rotation connection of the tension wheel, and greatly improving the convenience of equipment maintenance while ensuring the structural transmission stability.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Example:

[0030] Please refer to Figures 1 to 6 This utility model provides a tension stabilizing device for a single-wire cutting equipment, which aims to solve the structural defects of the existing technology, such as the lack of self-locking stability in the tension adjustment of the cutting wire and the cumbersome disassembly and maintenance of the tensioning wheel 505.

[0031] Please refer to Figure 1 and Figure 2 The tension stabilizing device of the single-wire cutting equipment includes a frame 1 and a cutting device 2 fixedly connected to the upper part of the frame 1. A U-shaped block 4 is fixedly connected to the bottom of the frame 1. The U-shaped block 4 is located in the lower part of the frame 1 and adopts a hollow structure design. The U-shaped block 4 provides an independent installation chamber for the internal transmission components. The front surface of the frame 1 is hinged with an inspection door 3. The inspection door 3 is divided into upper and lower groups, which correspond to the operating spaces of the cutting device 2 and the U-shaped block 4 respectively. A handle is fixedly installed on the front surface of the inspection door 3 to facilitate the operator to open it.

[0032] Please refer to Figure 3 and Figure 4 The U-shaped block 4 is internally equipped with a tension stabilizing mechanism 5. The tension stabilizing mechanism 5 includes a motor 501 fixedly connected to the bottom of the inner wall of the U-shaped block 4. The motor 501, as a power source, is horizontally mounted on the inner bottom wall of the U-shaped block 4. A worm gear 502 is fixedly connected to the output end of the motor 501. The worm gear 502 rotates with the motor 501 and serves as the active transmission component. A rotating shaft 503 is rotatably connected to the inner wall of the U-shaped block 4. A worm wheel 504 is fixedly connected to one end of the rotating shaft 503. The worm wheel 504 meshes with the worm gear 502. The axial direction of the worm gear 502 is parallel to the axial direction of the rotating shaft 503. The worm gear 504 and worm 502 are perpendicular to each other. The worm gear 504 and worm 502 mesh to transmit the rotational motion of the motor 501 to the rotating shaft 503 and use the mechanical self-locking characteristic to maintain the tension stability when stationary. The outer wall of the rotating shaft 503 is connected to the tension wheel 505 through the quick release mechanism 6. The rotating shaft 503 passes through the central through hole of the tension wheel 505. The inner side wall of the U-shaped block 4 is rotatably connected to multiple guide wheels 506. The outer wall of the guide wheel 506 is provided with an annular groove for limiting the displacement of the cutting line. The multiple guide wheels 506 are distributed around the tension wheel 505 along the cutting path of the cutting device 2.

[0033] Please refer to Figure 5 and Figure 6 The quick-release mechanism 6 has a limiting groove 601 formed on the outer wall of the rotating shaft 503. The limiting groove 601 extends along the axial direction of the rotating shaft 503 and has a depth and width adapted to the internal fitting structure of the tensioning wheel 505. At the same time, a limiting block 602 is fixedly connected to the inner side wall of the tensioning wheel 505. The shape and size of the limiting block 602 are adapted to the limiting groove 601. In the assembled state, the limiting block 602 slides and engages inside the limiting groove 601, which can limit the circumferential rotation of the tensioning wheel 505 relative to the rotating shaft 503, thereby ensuring that the rotating shaft 503 can stably drive the tensioning wheel 505 to rotate synchronously to adjust the tension of the cutting line.

[0034] To prevent the tensioning wheel 505 from detaching axially during operation, a fixing block 603 is slidably connected inside the limiting groove 601. The fixing block 603 is located outside the limiting block 602 to axially limit the tensioning wheel 505. A bolt 604 is threaded through the top of the fixing block 603. The end of the bolt 604 abuts against the inner wall of the limiting groove 601. By tightening the bolt 604, a clamping force can be generated to firmly lock the fixing block 603 in any position within the limiting groove 601, thereby preventing the tensioning wheel 505 from sliding outward. This ensures the stability of the connection and enables the quick disassembly and replacement of the tensioning wheel 505.

[0035] As a preferred embodiment, to enhance the support stability of the cantilever end of the pivot 503 and prevent bending under stress, please refer to... Figure 4 and Figure 5 A fixing groove 606 is provided on one side of the outer wall of the U-shaped block 4. A fixing plate 605 is embedded inside the fixing groove 606. The end of the rotating shaft 503 away from the worm gear 504 is rotatably connected to the side wall of the fixing plate 605. The fixing plate 605 and the U-shaped block 4 are connected by a multi-point fastening method. Specifically, bolts 607 are threaded at the four corners of the outer wall of the fixing plate 605. The shank of the bolts 607 passes through the fixing plate 605 and is threaded inside the side wall of the U-shaped block 4, effectively sharing the radial load generated by the rotating shaft 503 when the tension wheel 505 is under force, and ensuring the coaxiality and smooth operation of the entire transmission shaft system.

[0036] Working principle:

[0037] During the installation and debugging phase before cutting, the operator first opens the inspection door 3 hinged to the front surface of the frame 1, moves the tension wheel 505 to the installation position of the U-shaped block 4 at the bottom of the frame 1, and uses the quick-release mechanism 6 to install the tension wheel 505 onto the rotating shaft 503 inside the U-shaped block 4. Specifically, the operator aligns the limiting block 602 fixed on the inner wall of the tension wheel 505 with the limiting groove 601 opened on the outer wall of the rotating shaft 503 and pushes it in axially, so that the limiting block 602 slides and engages inside the limiting groove 601 to prevent the two from colliding. For rotation, the fixing block 603 is then slid into the limiting groove 601 and placed on the outside of the limiting block 602. By tightening the bolt 604 on the top of the fixing block 603, the end of the bolt 604 abuts against the inner wall of the limiting groove 601, thereby firmly locking the fixing block 603 in the limiting groove 601 and forming an axial block against the tensioning wheel 505. At the same time, by tightening the bolt 607, the fixing plate 605 embedded in the fixing groove 606 is fastened to the side wall of the U-shaped block 4, so that the end of the rotating shaft 503 is stably supported in the fixing plate 605.

[0038] After installation, the motor 501 located inside the U-shaped block 4 is started. The output end of the motor 501 drives the worm gear 502 to rotate. The worm gear 502 drives the worm wheel 504 and the rotating shaft 503 to rotate synchronously. The rotating shaft 503 drives the tension wheel 505 to rotate to adjust the tension of the cutting wire. Utilizing the self-locking characteristic of the transmission between the worm wheel 504 and the worm gear 502, the tension wheel 505 can maintain its position locked after the motor 501 stops, thereby maintaining stable tension. During the tension adjustment process, the cutting wire passes through multiple guide wheels 506 rotatably connected to the inner wall of the U-shaped block 4 in sequence. The guide wheels 506 use the annular groove on the outer wall to guide and limit the cutting wire to prevent lateral deviation. Finally, the cutting device 2 located in the upper part of the frame 1 is started to precisely cut the object.
