[0002] Diamond wire cutting machine tools, also known as diamond sand wire cutting machine tools, diamond wire saw machines, etc. Its working principle is that the diamond wire cutting machine tool uses the reciprocating motion of the sand wire to make the sand wire and the workpiece produce cutting to achieve the purpose of processing. Diamond wire cutting machine tools can be used to cut various metal and non-metal composite materials, parts to be cut, rock materials, gems, single crystal silicon, silicon carbide, polycrystalline silicon, refractory bricks, ceramics, epoxy boards, ferrites, etc., and are particularly suitable for cutting high-value, easy-to-break, brittle crystals of different hardness. Diamond wire cutting machine tools include single-wire cutting machine tools and multi-wire cutting machine tools. The sand wire used is also called diamond sand wire, corundum wire or diamond wire, which refers to the use of electroplating technology or resin bonding methods to fix diamond abrasives on a metal wire matrix.

[0003] When installing the diamond wire on an existing diamond wire cutting machine, it is often necessary to fix both ends of the diamond wire, but most of them use nuts to press the diamond wire for tightening, which is not convenient to operate. At the same time, when the cutting machine is in operation, the diamond wire is prone to loosening, causing both ends of the diamond wire to fall off, resulting in wire entanglement or even causing the diamond wire to fail to operate. Summary of the invention

[0004] The purpose of the present invention is to provide a wire fixing device which is convenient to operate and can prevent the diamond wire from loosening and falling off, and a diamond wire cutting machine tool thereof.

[0005] In order to achieve the above-mentioned purpose, the present invention provides a fixing line device, including a connecting shaft installed on a shaft ring, an upper shaft cover is fixedly installed on one end of the connecting shaft, a lower shaft cover is slidingly sleeved on the connecting shaft, the upper shaft cover is clamped with the lower shaft cover, and an elastic component is connected to the end of the lower shaft cover facing away from the upper shaft cover, and the elastic component is arranged along the sliding direction of the lower shaft cover.

[0006] As a preferred solution, there are at least two elastic components, and the elastic components are arranged at intervals along the circumference of the lower shaft cover.

[0007] As a preferred solution, adjacent elastic components are arranged at equal intervals.

[0008] As a preferred solution, the outer wall of the lower shaft cover protrudes radially to form a hand-operated portion.

[0009] As a preferred solution, the hand-operated portion is arranged around the outer wall of the lower shaft cover.

[0010] As a preferred solution, the lower shaft cover is provided with a closing tooth at one end facing the upper shaft cover, and the upper shaft cover is provided with an embedding groove for engaging with the closing tooth at one end facing the lower shaft cover, and the closing tooth and the embedding groove are arranged correspondingly.

[0011] As a preferred solution, at least two closing teeth are provided, the number of the embedding grooves is arranged corresponding to the number of the closing teeth, and the closing teeth are distributed at intervals along the circumference of the lower shaft cover.

[0012] A diamond wire cutting machine comprises a fixed wire device and a base, a cutting motor is mounted on the base, an output end of the cutting motor is connected to a shaft ring, a main winding shaft is coaxially mounted on the shaft ring, the shaft ring is provided with a fixed wire device, a middle winding shaft is mounted on the base, and a lower winding shaft is mounted below the middle winding shaft.

[0013] As a preferred solution, two fixing wire devices are provided, and the fixing wire devices are arranged at intervals along the circumference of the shaft ring.

[0014] As a preferred solution, a bracket is included, the base is installed on the bracket, a fixing plate is installed on the base, and the fixing plate and the base are respectively installed against the cutting motor.

[0015] Compared with the prior art, the wire fixing device of the embodiment of the present invention has the following beneficial effects: the lower shaft cover is pushed and squeezed along the connecting shaft toward the end away from the upper shaft cover to separate the lower shaft cover from the upper shaft cover, the diamond wire is wound on the connecting shaft between the upper shaft cover and the lower shaft cover, the diamond wire is pulled out from between the upper shaft cover and the lower shaft cover, and the lower shaft cover is pushed toward the upper shaft cover through the rebound of the elastic component, so that the upper shaft cover and the lower shaft cover are clamped, and the elastic component clamps the diamond wire.

At the same time, the fixing effect is good, and the diamond wire is prevented from loosening and falling off, ensuring the normal operation of the machine.

[0016] Compared with the prior art, a diamond wire cutting machine tool in an embodiment of the present invention has the beneficial effect that one end of the diamond wire is fixed by a fixing wire device, and the other end is wound along the main winding shaft, the middle winding shaft and the lower winding shaft, and finally returns to the fixing wire device for fixing, thereby effectively ensuring the stability of the diamond wire and preventing the diamond wire from falling off during operation. This solves the problem that when installing the diamond wire in the existing diamond wire cutting machine tool, both ends of the diamond wire need to be fixed, but most of them use nuts to press the diamond wire for tightening, which results in the diamond wire being easily loosened when the cutting machine tool is in operation, resulting in both ends of the diamond wire falling off, causing wire entanglement and even causing the diamond wire to fail to operate.

[0027] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] In the description of the present invention, it should be understood that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" used in the present invention to indicate the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0029] In the description of the present invention, it should be understood that the terms "connected", "connected", "fixed" and the like used in the present invention should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or a welding connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] like Figures 1 to 3 As shown, a fixing line device 50 of a preferred embodiment of an embodiment of the present invention includes a connecting shaft 51 installed on a shaft ring 22, an upper shaft cover 70 is fixedly installed on one end of the connecting shaft 51, a lower shaft cover 60 is slidably sleeved on the connecting shaft 51, the upper shaft cover 70 is snap-connected with the lower shaft cover 60, an elastic component 52 is connected to one end of the lower shaft cover 60 facing away from the upper shaft cover 70, and the elastic component 52 is arranged along the sliding direction of the lower shaft cover 60.

[0031] The wire fixing device 50 of the present invention pushes and squeezes the elastic component 52 along the connecting shaft 51 toward the end away from the upper shaft cover 70, so that the lower shaft cover 60 is separated from the upper shaft cover 70, and the diamond wire is wound on the connecting shaft 51 between the upper shaft cover 70 and the lower shaft cover 60, and the diamond wire is pulled out from between the upper shaft cover 70 and the lower shaft cover 60. Through the rebound of the elastic component 52, the lower shaft cover 60 is pushed toward the upper shaft cover 70, so that the upper shaft cover 70 and the lower shaft cover 60 are clamped, and the elastic component 52 clamps the diamond wire. The diamond wire can be fixed by only pushing the lower shaft cover 60 to move and then releasing it, which improves the convenience of operation and the control efficiency. At the same time, the fixing effect is good, and the diamond wire is prevented from loosening and falling off, ensuring the normal operation of the machine.

[0032] Specifically, the connecting shaft 51, the upper shaft cover 70 and the lower shaft cover 60 are coaxially installed.

[0033] Further, such as Figures 1 to 3 As shown, there are at least two elastic components 52, and the elastic components 52 are arranged at intervals along the circumference of the lower shaft cover 60. The more the number of elastic components 52, the greater the force of the elastic components 52 on the lower shaft cover 60 toward the upper shaft cover 70, so that the fixing effect of the diamond wire is better, and the loosening and falling of the diamond wire is prevented.

[0034] Further, such as Figures 1 to 3 As shown, adjacent elastic components 52 are arranged at equal intervals to make the force of the spring component on the lower shaft cover 60 more uniform, ensure the uniformity of the force of the circumferential connection between the lower shaft cover 60 and the upper shaft cover 70, and prevent the diamond wire from loosening or falling off. Preferably, the elastic component 52 is a spring.

[0035] Further, such as Figure 3 As shown, the outer wall of the lower shaft cover 60 protrudes radially to form a hand-operated portion 61. The protruding setting of the hand-operated portion 61 improves the operation recognition and accuracy of the lower shaft cover 60, and makes it easier to move the lower shaft cover 60 away from the end of the upper shaft cover 70 to achieve squeezing of the elastic component 52.

[0036] Further, such as Figure 3 As shown, the hand-operated part 61 is arranged around the outer wall of the lower shaft cover 60, so that the outer circumference of the lower shaft cover 60 is surrounded by the hand-operated part 61, ensuring that the lower shaft cover 60 can be operated by the hand-operated part 61 from all angles of the outer circumference. Preferably, the hand-operated part 61 is annular, and the annular hand-operated part 61 is directly mounted on the connecting shaft 51, and the annular hand-operated part 61 and the connecting shaft 51 are welded to complete the assembly of the hand-operated part 61 and the connecting shaft 51, which simplifies the assembly process and improves the assembly production efficiency.

[0037] Further, such as Figure 3 As shown, a closing tooth 62 is provided at one end of the lower shaft cover 60 facing the upper shaft cover 70, and an embedding groove 71 is provided at one end of the upper shaft cover 70 facing the lower shaft cover 60 for engaging with the closing tooth 62, and the positions of the closing tooth 62 and the embedding groove 71 are arranged correspondingly. When the diamond cutting machine shakes during use, the closing tooth 62 is engaged with the embedding groove 71, and the closing tooth 62 and the embedding groove 71 cannot rotate relative to each other, thereby ensuring that the diamond wire is wound around the connecting shaft 51, and at the same time, the closing tooth 62 and the embedding groove 71 press the diamond wire passing through between the closing tooth 62 and the embedding groove 71 through the force of the elastic component 52, effectively ensuring the fixing stability of the diamond wire and preventing the diamond wire from loosening and falling off during operation.

[0038] Further, such as Figure 3 As shown, at least two closing teeth 62 are provided, the number of embedded grooves 71 is provided corresponding to the number of closing teeth 62, and the closing teeth 62 are distributed at intervals along the circumference of the lower shaft cover 60. The more the number of closing teeth 62 is provided, the better the fixing stability of the diamond wire is, and the diamond wire is prevented from loosening and falling off due to circumferential movement between the lower shaft cover 60 and the upper shaft cover 70. Preferably, the closing tooth 62 is rectangular, and the inner wall shape of the embedded groove 71 matches the closing tooth 62. The closing tooth 62 is rectangular, so that there are more turning points after the closing tooth 62 is engaged with the embedded groove 71, which improves the fixing stability of the diamond wire and prevents the diamond wire from loosening and falling off.

[0039] like Figures 1 to 3As shown, a diamond wire cutting machine tool includes a fixed wire device 50 and a base 10, a cutting motor 20 is installed on the base 10, an output end of the cutting motor 20 is connected to a shaft ring 22, a main winding shaft 21 is coaxially installed on the shaft ring 22, the shaft ring 22 is provided with a fixed wire device 50, a middle winding shaft is installed on the base 10, and a lower winding shaft 44 is installed below the middle winding shaft. One end of the diamond wire is fixed by a wire fixing device 50, and the other end is wound along the main winding shaft 21, the middle winding shaft and the lower winding shaft 44, and finally returns to the wire fixing device 50 for fixing, which effectively ensures the stability of the diamond wire and prevents the diamond wire from falling off during operation. This solves the problem that when installing the diamond wire in the existing diamond wire cutting machine, the two ends of the diamond wire need to be fixed, but most of them use nuts to press the diamond wire for tightening, which causes the diamond wire to loosen easily when the cutting machine is in operation, causing the two ends of the diamond wire to fall off, causing the wire to be tangled or even causing the diamond wire to fail to operate.

[0040] Further, such as Figure 2 As shown, two fixing wire devices 50 are provided, and the fixing wire devices 50 are arranged at intervals along the circumference of the shaft ring 22. Specifically, the middle winding shaft includes a middle winding shaft 13 and a middle winding shaft 2 14, and the lower winding shaft 44 includes a lower winding shaft 1 45 and a lower winding shaft 2 46. One end of the diamond wire is fixed to one of the fixing wire devices 50, and the other end is successively passed through the main winding shaft 21, the middle winding shaft 2 14, the lower winding shaft 2 46, the lower winding shaft 1 45 and the middle winding shaft 1 13, and finally fixed by another fixing wire device 50. The two ends of the diamond wire are fixed by different fixing wire devices 50 respectively to avoid the diamond wires from being entangled with each other and affecting normal use.

[0041] Further, such as Figure 1 As shown, the bracket 11 includes a base 10 mounted on the bracket 11, a fixing plate 12 is mounted on the base 10, the fixing plate 12 and the base 10 are respectively mounted against the cutting motor 20, and the bracket 11 supports the base 10. Specifically, the cutting motor 20 is placed on the top surface of the base 10, and the fixing plate 12 is mounted against the back of the cutting motor 20 to fix the cutting motor 20 and prevent the cutting motor 20 from shaking during use, thereby improving the cutting accuracy.

[0042] The working process of the present invention is as follows: by pushing the lower shaft cover 60 toward one side of the elastic component 52, the elastic component 52 is squeezed, and the lower shaft cover 60 is separated from the upper shaft cover 70, and the first end of the diamond wire is wound on the connecting shaft 51 between the upper shaft cover 70 and the lower shaft cover 60, and the push on the lower shaft cover 60 is released. Under the rebound force of the elastic component 52, the lower shaft cover 60 moves toward the upper shaft cover 70, and then clamps one end of the diamond wire to complete the fixation of one end of the diamond wire, and the second end of the diamond wire passes through the main winding shaft 21, the middle winding shaft 14, the lower winding shaft 2 46, the lower winding shaft 1 45 and the middle winding shaft 1 13 in sequence. The fixing method of the second end of the diamond wire is the same as the first end fixing operation method, and then the fixation of the diamond wire is completed.

[0043] In summary, an embodiment of the present invention provides a fixed wire device 50 and a diamond wire cutting machine tool thereof, including a fixed wire device 50 and a base 10, a cutting motor 20 is installed on the base 10, the output end of the cutting motor 20 is connected to a shaft ring 22, a main winding shaft 21 is coaxially installed on the shaft ring 22, the shaft ring 22 is provided with a fixed wire device 50, a middle winding shaft is installed on the base 10, and a lower winding shaft 44 is installed below the middle winding shaft. One end of the diamond wire is fixed by a wire fixing device 50, and the other end is wound along the main winding shaft 21, the middle winding shaft and the lower winding shaft 44, and finally returns to the wire fixing device 50 for fixing, which effectively ensures the stability of the diamond wire and prevents the diamond wire from falling off during operation. This solves the problem that when installing the diamond wire in the existing diamond wire cutting machine, the two ends of the diamond wire need to be fixed, but most of them use nuts to press the diamond wire for tightening, which causes the diamond wire to loosen easily when the cutting machine is in operation, causing the two ends of the diamond wire to fall off, causing the wire to be tangled or even causing the diamond wire to fail to operate.

[0044] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
