Description

Technical Field

[0001] This utility model belongs to the field of wire abrasive cutting technology, and in particular relates to an auxiliary support guide wheel mechanism for a wire abrasive cutting machine. Background Technology

[0002] Wire cutting, also known as diamond wire cutting, is a machining method that uses a high-speed reciprocating "steel wire" with diamond abrasive particles on its surface as a cutting tool to cut hard and brittle materials through a grinding action. Wire cutting has advantages such as strong cutting ability, minimal cutting damage, high cutting precision, and the ability to process large-sized workpieces, and therefore it is widely used in industries such as photovoltaics, semiconductors, LEDs, magnetic materials, scientific research and laboratories, and gemstone processing.

[0003] A search revealed a wire cutting device (publication number CN211805449U) on the Chinese Patent website. This device avoids the problem of excessively high cutting speeds causing the wire to break or fracture, resulting in wasted resources. However, conventional wire cutting devices on the market often have a large distance between guide wheels to accommodate larger workpiece sizes, leading to increased wire bowing. When cutting smaller workpieces, this increased bowing creates significant cutting resistance, reducing cutting accuracy and efficiency. Therefore, this utility model provides an auxiliary support guide wheel mechanism for wire cutting machines, which is of great significance in addressing these issues. Utility Model Content

[0004] This invention provides an auxiliary support guide wheel mechanism for a wire cutting machine. The high-speed moving abrasive wire continuously grinds the workpiece or material until it is cut off. The Y-axis adjusting seat drives the second stud, along with the auxiliary guide wheel, to translate along the Y-axis adjusting groove. This changes the distance between the two auxiliary guide wheels. When cutting smaller workpieces or materials, the distance between the two auxiliary guide wheels can be shortened, reducing the arc of the wire and effectively decreasing cutting resistance, thereby greatly improving cutting accuracy and efficiency. During cutting, the electric telescopic rod drives the Z-axis adjusting plate, along with the two auxiliary guide wheels. The two auxiliary guide wheels are translated together along the Z-axis to adjust their heights according to the thickness of the auxiliary guide wheels until they are level with the heights of the main guide wheels. This ensures that the sand thread passes over each main guide wheel and auxiliary guide wheel simultaneously during winding, keeping the tension of the sand thread uniform during high-speed movement. At the same time, the X-axis adjustment plate can drive the entire auxiliary support assembly to translate along the inner wall of the fixed cylinder along the X-axis. The auxiliary guide wheels can then tighten or loosen the sand thread to adjust the tension according to the length of the sand thread, thus preventing the tension of the sand thread from being too high or too low. In summary, this solves the problems in the background technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model discloses an auxiliary support guide wheel mechanism for a wire cutting machine, comprising a base, a wire frame fixedly connected to the top of the base, and a motor mounted on the base. A first pulley is fixedly connected to the top of the output shaft of the motor. A pair of fixed plates are fixedly connected to the top of the wire frame, and the fixed plates are symmetrically distributed on the front and rear sides of the wire frame. Each fixed plate has a main guide wheel installed at both ends. A first wheel axle is fixedly connected to the bottom of the main guide wheel. The first wheel axle is rotatably connected to the fixed plate through a bearing, and a second pulley is fixedly connected to the bottom of the first wheel axle. The second pulley has the same diameter and thickness as the first pulley, and their heights are flush. A transmission belt drives the second pulley and the first pulley. A ring of abrasive wire is wound around the outer side of each main guide wheel. A fixed cylinder is fixedly connected to one side of the wire frame. An X-axis adjustment groove is opened on the top of the fixed cylinder, and an auxiliary support component is installed inside the fixed cylinder.

[0007] The auxiliary support assembly includes an X-axis adjusting plate inserted into a fixed cylinder. An electric telescopic rod is mounted on the bottom of one end of the X-axis adjusting plate, and a first stud is fixedly connected to the top of the other end of the X-axis adjusting plate. The first stud passes through an X-axis adjusting groove, and a first nut is threaded onto the first stud to mate with it. The top of the output shaft of the electric telescopic rod passes through the X-axis adjusting plate and is fixedly connected to a Z-axis adjusting plate. The Z-axis adjusting plate is rectangular, with a pair of Y-axis adjusting grooves at both ends. Y-axis adjusting seats are mounted on both top ends of the Z-axis adjusting plate. A second wheel axle is fixedly connected to the top of the Y-axis adjusting seat, and a pair of second studs are fixedly connected to the bottom of the Y-axis adjusting seat. A second nut is threaded onto the second studs to mate with it. An auxiliary guide wheel is mounted on the top of the Y-axis adjusting seat, and the auxiliary guide wheel is rotatably connected to the second wheel axle via a bearing. The sanding thread passes around the outer sides of the two auxiliary guide wheels.

[0008] Furthermore, the front and rear sides of the wire frame are both L-shaped, and a pair of reinforcing ribs are fixedly connected to both sides of the wire frame. The reinforcing ribs are triangular and symmetrically distributed on the front and rear sides of the wire frame, and the top of the reinforcing ribs is fixedly connected to the bottom of the fixing plate.

[0009] Furthermore, the diameters and thicknesses of each of the main guide wheels are equal, and the heights of each of the main guide wheels are level. The diameters and thicknesses of each of the auxiliary guide wheels are equal, and the diameter of the auxiliary guide wheel is smaller than that of the main guide wheel.

[0010] Furthermore, each of the main guide wheels and each auxiliary guide wheel has a groove on its outer side, and the bottom of the groove is arc-shaped.

[0011] Furthermore, the fixed cylinder is a square cylindrical structure, the X-axis adjusting plate is rectangular, and its width and thickness are equal to the inner wall length and width of the fixed cylinder, respectively. The X-axis adjusting groove is rectangular, and its width is equal to the diameter of the first stud.

[0012] Furthermore, the Y-axis adjustment groove is rectangular and symmetrically distributed at both ends of the Z-axis adjustment plate, and the width of the Y-axis adjustment groove is equal to the diameter of the second stud, and the center of each second stud corresponds one-to-one with the center of each Y-axis adjustment groove.

[0013] The present invention has the following advantages over the prior art:

[0014] (1) The auxiliary guide wheel is used instead of the main guide wheel, and the wire bow can be adjusted according to the workpiece size, resulting in high cutting accuracy and efficiency: The high-speed moving abrasive wire can continuously grind the workpiece or material until it is cut off. The Y-axis adjustment seat can drive the second stud together with the auxiliary guide wheel to move along the Y-axis adjustment groove in the Y-axis direction. At this time, the distance between the two auxiliary guide wheels will change. When it is necessary to cut a small workpiece or material, the distance between the two auxiliary guide wheels can be shortened. At this time, the wire bow is reduced, which can effectively reduce the cutting resistance and thus greatly improve the cutting accuracy and efficiency.

[0015] (2) By translating in the Y and Z directions, it can flexibly adapt to different cutting scenarios: During cutting, by driving the electric telescopic rod, the Z-axis adjustment plate and the two auxiliary guide wheels can be translated in the Z-axis direction together, so as to adjust the height of the two auxiliary guide wheels according to the thickness of the auxiliary guide wheels, until the height of the two auxiliary guide wheels is level with the height of each main guide wheel, so as to ensure that when winding the sand thread, the sand thread passes around each main guide wheel and auxiliary guide wheel at the same time, so that the tension of the sand thread remains uniform when moving at high speed. At the same time, the X-axis adjustment plate can drive the entire auxiliary support assembly to translate in the X-axis direction along the inner wall of the fixed cylinder. At this time, the sand thread can be tightened or loosened by the auxiliary guide wheels, so as to adjust the tension according to the length of the sand thread, thereby avoiding the tension of the sand thread being too large or too small.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] Please see Figure 1-7As shown, an auxiliary support guide wheel mechanism for a wire cutting machine according to this utility model includes a base 1, a wire frame 2 fixedly connected to the top of the base 1, and a motor 3 mounted on the base 1. A first pulley 4 is fixedly connected to the top of the output shaft of the motor 3. A pair of fixing plates 5 are fixedly connected to the top of the wire frame 2, symmetrically distributed on the front and rear sides of the wire frame 2. Each fixing plate 5 has a main guide wheel 6 mounted at both ends. A first wheel shaft 7 is fixedly connected to the bottom of the main guide wheel 6. The first wheel shaft 7 is rotatably connected to the fixing plate 5 through a bearing, and a second pulley 8 is fixedly connected to the bottom end of the first wheel shaft 7. The diameter of the second pulley 8 is the same as that of the first pulley 4. The thickness and height are equal, and the second pulley 8 and the first pulley 4 are connected by a transmission belt 9. A ring of sand wire 10 is wound around the outside of each main pulley 6. The first pulley 4 can be rotated by the drive motor 3. When the first pulley 4 rotates, it can drive the second pulley 8 and one of the main pulleys 6 to rotate through the transmission belt 9. When the main pulley 6 rotates, it will drive the sand wire 10 to move in a high speed in one direction and drive each main pulley 6 to rotate together. A fixed cylinder 11 is fixedly connected to one side of the wire frame 2. An X-direction adjustment groove 12 is opened on the top of the fixed cylinder 11, and an auxiliary support component is installed inside the fixed cylinder 11.

[0030] The auxiliary support assembly includes an X-axis adjusting plate 13, which is inserted into the fixed cylinder 11. An electric telescopic rod 14 is installed at one bottom end of the X-axis adjusting plate 13, and a first stud 15 is fixedly connected to the top end of the other end of the X-axis adjusting plate 13. The first stud 15 passes through an X-axis adjusting groove 12, and a first nut 16 is threaded onto the first stud 15 to mate with it. The top end of the output shaft of the electric telescopic rod 14 passes through the X-axis adjusting plate 13 and is fixedly connected to a Z-axis adjusting plate 17. The Z-axis adjusting plate 17 is rectangular, with a pair of Y-axis adjusting grooves 18 at both ends. Y-axis adjusting seats 19 are installed at both ends of the top of the Z-axis adjusting plate 17, and a second wheel axle 2 is fixedly connected to the top of the Y-axis adjusting seats 19. 0, and a pair of second studs 21 are fixedly connected to the bottom of the Y-axis adjusting seat 19. The second studs 21 are threaded with a second nut 22 that matches them. An auxiliary guide wheel 23 is installed on the top of the Y-axis adjusting seat 19. The auxiliary guide wheel 23 is rotatably connected to the second wheel shaft 20 through a bearing. The abrasive wire 10 passes around the outside of the two auxiliary guide wheels 23 respectively. When the abrasive wire 10 moves at high speed in one direction under the drive of the main guide wheel 6, it can drive the two auxiliary guide wheels 23 to rotate together. When the workpiece or material moves towards the auxiliary guide wheel 23 through the feeding mechanism and comes into contact with the abrasive wire 10, the high-speed moving abrasive wire 10 can continuously grind the workpiece or material until the workpiece or material is cut off.

[0031] The front and rear sides of the wire frame 2 are both L-shaped, and a pair of reinforcing ribs 24 are fixedly connected to both sides of the wire frame 2. The reinforcing ribs 24 are triangular and symmetrically distributed on the front and rear sides of the wire frame 2. The top of the reinforcing ribs 24 is fixedly connected to the bottom of the fixing plate 5. The bottom of the fixing plate 5 can be supported by the reinforcing ribs 24 to ensure that the top surface of the fixing plate 5 and the wire frame 2 always remain parallel, thereby preventing the fixing plate 5 from bending and deforming due to long-term stress, which would cause the main guide wheels 6 to tilt.

[0032] The diameters and thicknesses of the main guide wheels 6 are equal, and their heights are aligned. The diameters and thicknesses of the auxiliary guide wheels 23 are also equal, with the diameter of the auxiliary guide wheels 23 being smaller than that of the main guide wheels 6. By driving the electric telescopic rod 14, the Z-axis adjustment plate 17, along with the two auxiliary guide wheels 23, can be moved in the Z-axis direction to adjust the height of the two auxiliary guide wheels 23 according to their thickness, until the height of the two auxiliary guide wheels 23 is aligned with the height of the main guide wheels 6. This ensures that when winding the sand thread 10, the sand thread 10 simultaneously passes over each main guide wheel 6 and auxiliary guide wheel 23, so that the tension of the sand thread 10 remains uniform during high-speed movement. The electric telescopic rod 14 has a stroke of 50-100mm and a stroke accuracy of ±0.1mm, and its precise position can be controlled by an external PLC control system.

[0033] Each main guide wheel 6 and each auxiliary guide wheel 23 has a groove 25 on its outer side. The bottom of the groove 25 is arc-shaped. When the sand thread 10 is wound around the outer side of the main guide wheel 6 and the auxiliary guide wheel 23, it can fit into the groove 25. At this time, the groove 25 can play a limiting role to prevent the sand thread 10 from deviating and becoming detached when moving at high speed.

[0034] The fixed cylinder 11 has a square cylindrical structure, the X-axis adjusting plate 13 is rectangular, and its width and thickness are equal to the length and width of the inner wall of the fixed cylinder 11, respectively. The X-axis adjusting groove 12 is rectangular, and its width is equal to the diameter of the first stud 15. The X-axis adjusting plate 13 can drive the entire auxiliary support assembly to translate along the inner wall of the fixed cylinder 11 in the X-axis direction. When the length of the sanding wire 10 remains unchanged, the sanding wire 10 can be tightened or loosened by the auxiliary guide wheel 23 so as to adjust the tension of the sanding wire 10 as needed, thereby avoiding excessive or insufficient tension. After the tension adjustment is completed, the first nut 16 can be threaded onto the first stud 15 and tightened to fix the X-axis position of the two auxiliary guide wheels 23.

[0035] The Y-axis adjustment groove 18 is rectangular and symmetrically distributed at both ends of the Z-axis adjustment plate 17. The width of the Y-axis adjustment groove 18 is equal to the diameter of the second stud 21. The center of each second stud 21 corresponds one-to-one with the center of each Y-axis adjustment groove 18. Each second stud 21 can pass through its corresponding Y-axis adjustment groove 18. The second nut 22 is then threaded onto each second stud 21 and tightened. The Y-axis adjustment seat 19, together with the auxiliary guide wheel 23, is fixedly installed on the Z-axis adjustment plate 17 through the mutual cooperation between the second stud 21 and the second nut 22. On the section plate 17, the Y-axis adjustment seat 19 can drive the second stud 21 and the auxiliary guide wheel 23 to move along the Y-axis adjustment groove 18 in the Y-axis direction. At this time, the distance between the two auxiliary guide wheels 23 will change. When it is necessary to cut a small workpiece or material, the distance between the two auxiliary guide wheels 23 can be shortened. At this time, the bow line is reduced, which can effectively reduce the cutting resistance and thus greatly improve the cutting accuracy and efficiency. After the distance adjustment is completed, the second nuts 22 on each second stud 21 can be tightened to fix the distance between the two auxiliary guide wheels 23.

[0036] All standard parts used in the application documents can be purchased from the market. All components in this application document can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The electrical components mentioned in this document are all electrically connected to the external main controller and power supply, and the main controller is a conventional known device that can play a control role.

[0037] The working principle of this utility model is as follows:

[0038] In use, this invention drives a motor 3 to rotate a first pulley 4. When the first pulley 4 rotates, it drives a second pulley 8, along with one of the main pulleys 6, to rotate via a transmission belt 9. When the main pulley 6 rotates, it drives the abrasive wire 10 to move at high speed in one direction, simultaneously rotating each main pulley 6 and each auxiliary guide wheel 23. When the workpiece or material moves towards the auxiliary guide wheel 23 via the feeding mechanism and comes into contact with the abrasive wire 10, the high-speed abrasive wire 10 continuously grinds the workpiece or material until it is cut. During cutting, the electric telescopic rod 14 drives the Z-axis adjustment plate 17, along with the two auxiliary guide wheels 23, to translate along the Z-axis. This allows the height of the two auxiliary guide wheels 23 to be adjusted according to their thickness until they are level with the height of each main pulley 6. This ensures that when the abrasive wire 10 is wound, it simultaneously passes over each main pulley 6 and auxiliary guide wheel 23, maintaining uniform tension during high-speed movement. Meanwhile, the X-axis adjusting plate 13 can drive the entire auxiliary support assembly to translate along the inner wall of the fixed cylinder 11 in the X-axis direction. At this time, the auxiliary guide wheel 23 can tighten or loosen the abrasive wire 10 so as to adjust the tension according to the different lengths of the abrasive wire 10, thereby avoiding excessive or insufficient tension of the abrasive wire 10. After the tension adjustment is completed, the first nut 16 can be threaded onto the first stud 15 and tightened to fix the X-axis position of the two auxiliary guide wheels 23. In addition, the Y-axis adjusting seat 19 can drive the second stud 21 together with the auxiliary guide wheel 23 to translate along the Y-axis adjusting groove 18. At this time, the distance between the two auxiliary guide wheels 23 will change. When it is necessary to cut small workpieces or materials, the distance between the two auxiliary guide wheels 23 can be shortened. At this time, the bow line is reduced, thereby effectively reducing the cutting resistance and greatly improving the cutting accuracy and efficiency. After the distance adjustment is completed, the second nut 22 can be threaded onto each of the second studs 21 and tightened to fix the distance between the two auxiliary guide wheels 23.
