Description

Technical Field

[0001] The present invention relates to the technical field of cutting equipment, and in particular to an auxiliary support device for crystal rod cutting and a single-wire cutting machine. Background Art

[0002] Single-wire cutting machines are mainly used for head removal, truncation, squaring, small-quantity slicing and multiple-cut processing of hard and brittle materials such as sapphire, silicon carbide, tungsten alloy, molybdenum alloy, crystal, scintillating crystal, semiconductors, ceramics, ferroelectric crystals, and magnetic materials. They are driven by precision servo motors and reducers, as well as a top-down wire movement method, to achieve more accurate and uniform wire feeding, thereby improving processing efficiency and surface quality.

[0003] However, the processing table of the existing single-wire cutting machine usually adopts a V-groove structure to stably support the column of the crystal rod, but the processing table of the V-groove structure can only support the segmentation of the crystal rod. When cutting the end face of the crystal rod, since the end face of the crystal rod cannot be stably placed in the V-groove, the cutting surface will have serious edge collapse when the cutting line cuts through the end face of the crystal rod. At the same time, the cutting block formed after cutting will fall into the inside of the processing table due to loss of center of gravity, thereby causing a large area of ​​collision on the surface of the cutting block, seriously affecting the qualified rate of the product. To solve this problem, the practice in the prior art is to design another single-wire cutting machine specifically for cutting the end face of the crystal rod, that is, one single-wire cutting machine is specifically used for segmented cutting of the crystal rod column, and the other cutting machine is specifically used for block cutting of the end face of the crystal rod. However, designing another single-wire cutting machine specifically for cutting the end face of the crystal rod will greatly increase the processing cost. At the same time, the crystal rod needs to be transported between the two single-wire cutting machines, resulting in further increase in labor costs. Summary of the invention

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0040] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0041] like Figure 1 and Figure 4 As shown, the present invention provides an auxiliary support device for crystal rod cutting (hereinafter referred to as the auxiliary support device), which is detachably arranged on a groove processing table 5, wherein the groove processing table 5 is provided with a processing groove and a cutting seam 6, and optionally, the processing groove is a V-shaped groove. Specifically, the auxiliary support device includes a first support device 1 and a second support device 2, and the first support device 1 and the second support device 2 are respectively arranged on both sides of the cutting seam 6. Specifically, the first support device 1 includes a first support platform 11, and the first support platform 11 can provide a horizontal first support surface, and the second support device 2 includes a second support platform 21, and the second support platform 21 can provide a horizontal second support surface, and the first support surface and the second support surface are arranged coplanar.

[0042] When the first support device 1 and the second support device 2 are placed on the slot processing table 5, the auxiliary support device is in a working state. At this time, the first support platform 11 and the second support platform 21 can stably support the end face of the crystal rod, so that the stability of the single-wire saw when cutting the end face of the crystal rod is improved, thereby avoiding serious edge collapse and falling of the cut block after the end face of the crystal rod is cut through. When the first support device 1 and the second support device 2 are removed from the slot processing table 5, the auxiliary support device is in an idle state. At this time, the processing groove of the slot processing table 5 can stably support the cylindrical surface of the crystal rod, so that the single-wire saw can cut the cylindrical surface of the crystal rod in sections.

[0043] Optionally, in consideration of material, weight, cost, etc., the first supporting device 1 and the second supporting device 2 in this embodiment are made of PVC material. It is understandable that in some other embodiments, the auxiliary supporting device can also be made of other materials as needed, which is not limited here.

[0044] To ensure that the first supporting device 1 can be stably placed on the grooved processing table 5 and facilitate the detachable connection between the two, as shown in FIG. Figure 1 As shown, the first supporting device 1 also includes a first limiting structure 12, which is arranged below the first supporting platform 11. The first limiting structure 12 can be connected to the groove processing table 5 in a limiting manner, thereby limiting the movement of the first supporting device 1 on the groove processing table 5.

[0045] Alternatively, if Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the grooved processing table 5 includes a first processing table 51 arranged on one side of the cutting seam 6, and the first processing table 51 is provided with a first transverse groove 511 and a first oblique groove 512 at intervals. According to the specific structure of the first processing table 51, the first limiting structure 12 includes a first limiting plate 121, a second limiting plate 122, a third limiting plate 123, a fourth limiting plate 124 and a fifth limiting plate 125, and the first limiting plate 121, the second limiting plate 122, the third limiting plate 123, the fourth limiting plate 124 and the fifth limiting plate 125 are all arranged on the bottom surface of the first processing table 51, wherein the first limiting plate 121 and the second limiting plate 122 are respectively fitted with the two outer side surfaces of the first processing table 51 in the length direction, the third limiting plate 123 is clamped in the first transverse groove 511, the fourth limiting plate 124 is fitted with the cross section of the first processing table 51 forming the cutting seam 6, and the fifth limiting plate 125 is clamped in the first oblique groove 512.

[0046] By setting the first limiting plate 121, the second limiting plate 122, the third limiting plate 123, the fourth limiting plate 124 and the fifth limiting plate 125, the first support device 1 can be firmly fixed on the first processing table 51, thereby realizing the first support device 1 to stably support the end face of the crystal rod, and the connection method between the limiting plate and the groove makes it very convenient to disassemble the first support device 1 and the groove processing table 5. At the same time, the limiting plate designed according to the structure of the groove processing table 5 itself is not only simple in structure, but also can further reduce the production cost of the auxiliary support device. Of course, in other embodiments, if the number or shape of the grooves provided on the first processing table 51 changes, the number and shape of the limiting plates can also be flexibly adjusted.

[0047] To ensure that the second supporting device 2 can be stably placed on the grooved processing table 5 and facilitate the detachable connection between the two, as shown in FIG. Figure 1 As shown, the second support device 2 also includes a second limiting structure 22, which is arranged below the second support platform 21. The second limiting structure 22 can be connected to the groove processing table 5 to limit the movement of the second support device 2 on the groove processing table 5.

[0048] Alternatively, if Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the grooved processing table 5 also includes a second processing table 52 arranged on the other side of the cutting seam 6, and the second processing table 52 is provided with a second transverse groove 521 and a third transverse groove 522 at intervals. According to the specific structure of the second processing table 52, the second limiting structure 22 includes a sixth limiting plate 221, a seventh limiting plate 222, an eighth limiting plate 223 and a ninth limiting plate 224, and the sixth limiting plate 221, the seventh limiting plate 222, the eighth limiting plate 223 and the ninth limiting plate 224 are arranged on the bottom surface of the second processing table 52, wherein the sixth limiting plate 221 is clamped in the third transverse groove 522, the seventh limiting plate 222 is clamped in the second transverse groove 521, and the eighth limiting plate 223 and the ninth limiting plate 224 are respectively fitted with the two inner side surfaces of the second processing table 52 in the length direction.

[0049] By setting the sixth limiting plate 221, the seventh limiting plate 222, the eighth limiting plate 223 and the ninth limiting plate 224, the second support device 2 can be firmly fixed on the second processing table 52, thereby realizing the second support device 2 to stably support the end face of the crystal rod, and the connection method between the limiting plate and the groove makes it very convenient to disassemble the second support device 2 and the groove processing table 5. At the same time, the limiting plate designed according to the structure of the groove processing table 5 itself is not only simple in structure, but also can further reduce the production cost of the auxiliary support device. Of course, in other embodiments, if the number or shape of the grooves provided on the second processing table 52 changes, the number and shape of the limiting plates can also be flexibly adjusted.

[0050] It is understandable that in some other embodiments, the first limiting structure 12 and the second limiting structure 22 are not limited to limiting plate structures, and can be adaptively designed according to the structure of the groove processing table 5 itself. As long as the first supporting device 1 and the second supporting device 2 can be stably limited on the groove processing table 5, no limitation is made here.

[0051] In order to improve the stability of the crystal rod on the first supporting device 1 and the second supporting device 2, as Figure 1 As shown, in this embodiment, a first limiting assembly 3 is further provided on the first supporting device 1, and a second limiting assembly 4 is further provided on the second supporting device 2. The first limiting assembly 3 and the second limiting assembly 4 can limit the crystal rod. It can be understood that the limiting here can be a circumferential limiting or a limiting from top to bottom on the end surface.

[0052] When the crystal rod needs to be limited circumferentially, continue to refer to Figure 1 As shown, the first limiting assembly 3 includes a first support rod 32 and a first clamp 33, wherein the first support rod 32 is arranged on the first support platform 11, and the first clamp 33 is arranged on the first support rod 32. The second limiting assembly 4 includes a second support rod 42 and a second clamp 43, wherein the second support rod 42 is arranged on the second support platform 21, and the second clamp 43 is arranged on the second support rod 42. By setting the first limiting assembly 3 and the second limiting assembly 4, when the end face of the crystal rod is cut, a limiting space for limiting the crystal rod is formed between the first clamp 33 and the second clamp 43, and the crystal rod is placed in the limiting space to prevent the crystal rod from moving on the first support platform 11 and the second support platform 21 during the cutting process, and further avoid the edge collapse and the falling of the cutting block after the end face of the crystal rod is cut through.

[0053] Further optionally, if Figure 1As shown, in this embodiment, the first support platform 11 is also provided with a first slide rail 111, and the first limit assembly 3 also includes a first slider 31, wherein the first support rod 32 is arranged on the first slider 31, and the first slider 31 is slidably arranged on the first slide rail 111. The second support platform 21 is provided with a second slide rail 211, and the second limit assembly 4 also includes a second slider 41, wherein the second support rod 42 is arranged on the second slider 41, and the second slider 41 is slidably arranged on the second slide rail 211. By setting the first limit assembly 3 to be slidably arranged on the first support platform 11 and the second limit assembly 4 to be slidably arranged on the second support platform 21, it is possible to limit the crystal rods of different diameters, thereby improving the applicability of the auxiliary support device. It is understandable that in some other embodiments, only one of the first limit assembly 3 and the second limit assembly 4 can be slidable, and the other can be fixed, as long as the crystal rods of different diameters can be clamped, and no limitation is made here.

[0054] Further optionally, if Figure 1 As shown, in this embodiment, the first clamp 33 is slidably disposed on the first support rod 32, and the second clamp 43 is slidably disposed on the second support rod 42. By setting the height of the first clamp 33 and the second clamp 43 to be adjustable, when limiting the crystal rods of different heights, the height of the first clamp 33 and the second clamp 43 can be changed so that they are located in the middle of the crystal rod, thereby achieving a better limiting effect. It is understandable that in some other embodiments, the first support rod 32 can also be set as a telescopic rod, and the first clamp 33 is set at the movable end of the first support rod 32; or the second support rod 42 is a telescopic rod, and the second clamp 43 is set at the movable end of the second support rod 42. As long as the height of the first clamp 33 and the second clamp 43 can be adjusted, there is no limitation here.

[0055] Further optionally, if Figure 1 As shown, in this embodiment, the first clamping jaw 33 is detachably connected to the first support rod 32, and the second clamping jaw 43 is detachably connected to the second support rod 42. By arranging the first clamping jaw 33 to be detachably connected to the first support rod 32 and the second clamping jaw 43 to be detachably connected to the second support rod 42, when limiting the position of the crystal rods with different cylinders, the first clamping jaw 33 and the second clamping jaw 43 adapted to the cylinder of the crystal rod can be replaced, thereby achieving effective limiting of the cylinder of the crystal rod. At the same time, when the first clamping jaw 33 and the second clamping jaw 43 are damaged, they can also be conveniently repaired or replaced. It can be understood that in some other embodiments, only one of the first clamping jaw 33 and the second clamping jaw 43 can be detachably connected, which is not limited here.

[0056] Furthermore, in this embodiment, the clamping surface of the first clamping jaw 33 is provided with a first gasket, and the clamping surface of the second clamping jaw 43 is provided with a second gasket. The material of the first gasket and the second gasket can be rubber, silicone or soft plastic, etc., as long as it can avoid damage or contamination to the surface of the crystal rod, and no limitation is made here. By providing the first gasket and the second gasket, it can be avoided that the first clamping jaw 33 and the second clamping jaw 43 will avoid contamination or damage to the surface of the crystal rod when limiting the position of the crystal rod.

[0057] The present invention also provides a single-wire cutting machine, which includes a slot processing table 5 and an auxiliary support device for cutting a crystal rod as described above, wherein the auxiliary support device is detachably placed on the slot processing table 5, and the slot processing table 5 is provided with a V-shaped groove for supporting the cylindrical surface of the crystal rod. The single-wire cutting machine can realize two processing and cutting methods: cutting the cylindrical surface of the crystal rod and cutting the end surface of the crystal rod. Specifically, when the crystal rod needs to be cut on the cylindrical surface, the auxiliary support device is not placed on the slot processing table 5, and the crystal rod is directly placed on the slot processing table 5 for cutting. When the crystal rod needs to be cut on the end surface, the auxiliary support device is placed on the slot processing table 5, and then the crystal rod is placed on the auxiliary support device for cutting.

[0058] The single-wire cutting machine provided by the present invention can realize switching between two different processing methods, namely, crystal rod column cutting and crystal rod end face dicing, on one single-wire cutting machine by selecting whether to place an auxiliary supporting device or not. Compared with the prior art which requires two single-wire cutting machines to respectively perform crystal rod column cutting and crystal rod end face dicing, the processing cost is reduced. At the same time, both cutting methods can be completed on one single-wire cutting machine, without the need to carry the crystal rod back and forth, thereby simplifying manual loading and unloading operations, and shortening the operation time from the original 50s to 15s, thereby greatly saving labor costs.

[0059] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
