Description

[Technical field]

[0001] The invention relates to the technical field of wire saw machines, in particular to an improved wire saw machine. [Background technology]

[0002] A wire saw machine is a device that uses high-speed linear motion of a diamond wire saw to achieve material cutting. It is suitable for cutting various hard materials (such as glass, ceramics, etc.). It is currently mainly used in building materials, plate cutting and other fields.

[0003] like Figure 1 As shown, the existing wire saw machine usually includes two supporting columns 1', a supporting platform 2', two flywheel mechanisms 3', two lifting mechanisms 4' and a wire saw blade (not shown), the supporting column 1' is arranged on the supporting platform 2', each flywheel mechanism 3' is assembled and connected with a supporting column 1' through a lifting mechanism 4', and the wire saw blade is wound between the two flywheel mechanisms 3' to form a closed loop connection; wherein, as shown in FIG. Figure 2 As shown, each lifting mechanism 4' includes a lifting outer frame 41', a screw 42', 8 cylindrical rollers 43' and a plurality of auxiliary wheels 44'. The lifting outer frame 41' is slidably assembled on the supporting column 1' through the cylindrical rollers 43' and the auxiliary wheels 44'. The cylindrical rollers 43' and the auxiliary wheels 44' are both against the outside of the supporting column 1'. The supporting column 1' and the lifting outer frame 41' are connected through the screw 42'. However, the above existing lifting mechanisms have the following defects: 1. The cylindrical rollers and the supporting columns are in contact with the plane through the cylindrical surface, and the lifting stability is poor, which will affect the cutting accuracy; 2. The overall structure is complex, the cost is high, and the installation is inconvenient.

[0004] Of course, in response to the problem of poor lifting stability, the Chinese utility model patent with application number CN201911200123.9 discloses a tree-shaped lifting U-shaped slide rail type stereoscopic car park, which specifically discloses a solution of using hollow square tubes and V-shaped rollers to improve stability, but the position of the V-shaped roller cannot be adjusted. Once the V-shaped roller fails to accurately fit the hollow square tube, the friction between the V-shaped roller and the hollow square tube will increase, which will not only cause a large working friction noise and affect the smoothness of lifting, but also the V-shaped roller and the hollow square tube are prone to wear and damage due to excessive friction; in addition, the V-shaped roller in this solution is located on the side facing each other of the two hollow square tubes, and the V-shaped roller has only one-sided support, which not only has poor support stability, but also the V-shaped roller will affect the setting of the diagonal tie rod between the two hollow square tubes.

[0005] In view of the above-mentioned problems, the inventor of this case conducted in-depth research on the issue, which led to the creation of this case. [Summary of the invention]

[0054] A lifting guide protrusion 11 is formed in the middle of both sides of the support column 1 along the vertical direction, and the lifting guide protrusion 11 cooperates with the lifting mechanism 2 so that the lifting mechanism 2 can perform lifting movement along the lifting guide protrusion 11;

At the same time, a walking wheel adjustment assembly 27 is provided between the support shaft 26 and the first walking wheel 23. During use, the walking wheel adjustment assembly 27 can be used to adjust and correct the position of the first walking wheel 23 so that the groove of the first walking wheel 23 can be accurately matched with the lifting guide protrusion 11 on the support column 1. In this way, on the one hand, the working friction noise between the first walking wheel 23 and the lifting guide protrusion 11 can be effectively reduced, while ensuring the smoothness of lifting and lowering. On the other hand, the wear and damage caused by excessive friction between the first walking wheel 23 and the lifting guide protrusion 11 can be reduced, thereby helping to improve the service life; in addition, both ends of the support shaft 26 are connected to the movable outer frame 21, so that both ends of the first walking wheel 23 can be effectively supported, which can ensure the support stability of the entire first walking wheel 23.

[0057] In some embodiments of the present invention, in order to better achieve accurate adjustment of the position of the first running wheel 23, the running wheel adjustment assembly 27 includes an adjustment sleeve 271 and a first nut member 272;

[0058] An assembly through hole 232 is provided in the middle of the first walking wheel 23 along the axial direction of the support shaft body 26, and expanded straight sections 233 are formed at both ends of the assembly through hole 232, that is, the diameter of the expanded straight section 233 is larger than the diameter of the assembly through hole 232, and a bearing 273 is installed in the expanded straight section 233, and the support shaft body 26 passes through the bearing 273 and the assembly through hole 232; a limited step surface 234 is formed at one end of the two expanded straight sections 233 facing each other, and the bearing 273 abuts against the limited step surface 234; in the specific implementation of the present invention, the diameter of the assembly through hole 232 is designed to be larger than the diameter of the support shaft body 26, so that after assembly, the entire first walking wheel 23 will not directly contact the support shaft body 26, which can avoid the support shaft body 26 from causing adverse effects on the rotation of the first walking wheel 23;

[0059] The support shaft 26 is slidably provided with an adjustment sleeve 271 at both ends of the first traveling wheel 23, one end of the adjustment sleeve 271 abuts against the bearing 273, and a gap 274 is left between the other end of the adjustment sleeve 271 and the inner wall of the movable outer frame 21, so that the adjustment sleeve 271 can move to adjust the position of the first traveling wheel 23, and the outer wall of the other end of the adjustment sleeve 271 is formed with a first external thread section 2711, and the first nut member 272 is screwed on the first external thread section 2711, and the first nut member 272 abuts against the inner wall of the movable outer frame 21. When the walking wheel adjustment assembly 27 of the present invention is used in practice, when the groove of the first walking wheel 23 cannot be precisely matched with the lifting guide protrusion 11 on the supporting column 1, the first nut member 272 on one of the adjusting sleeves 271 can be rotated toward the inner wall of the movable outer frame 21, and the first nut member 272 on the other adjusting sleeve 271 can be rotated away from the inner wall of the movable outer frame 21. The adjusting sleeve 271 can be used to push the first walking wheel 23 and the bearing 273 together for fine-tuning of the position, thereby ensuring that the groove of the first walking wheel 23 can be precisely matched with the lifting guide protrusion 11 on the supporting column 1.

[0060] Furthermore, the adjusting sleeve 271 is provided with a sealing member 281 at one end close to the bearing 273, and an oil storage chamber 282 is formed between the sealing member 281 and the bearing 273, and the oil storage chamber 282 is used to store lubricating grease; the outer portion of the sealing member 281 is provided with a sealing end cover 283, and the sealing end cover 283 is locked and connected with the end face of the first running wheel 23, and the sealing end cover 283 can rotate together with the first running wheel 23 during operation.

[0061] The present invention provides a seal 281 on the outer side of the bearing 273 and forms an oil storage chamber 282 between the seal 281 and the bearing 273, so that during specific use, the bearing 273 can be lubricated by the lubricating grease stored in the oil storage chamber 282, ensuring that the bearing 273 will not affect the smooth rotation of the first running wheel 23 due to rust or other reasons; at the same time, a sealing end cover 283 is sleeved on the outside of the seal 281, and the sealing end cover 283 can cooperate with the seal 281 to play the role of oil seal and seal, that is, on the one hand, it can prevent the lubricating grease in the oil storage chamber 282 from leaking to the outside, and on the other hand, it can prevent external dust from entering the bearing 273 and causing adverse effects on the bearing 273.

[0062] Furthermore, at least two first nut members 272 are screwed onto the first external thread section 2711, and a spring sheet 275 is provided between the two first nut members 272. When the present invention is used, it is necessary to make the first nut members 272 on both sides of the spring sheet 275 contact the spring sheet 275, so that after the position of the first nut member 272 is adjusted, the elastic force generated by the spring sheet 275 can be used to tighten the first nut members 272 on both sides, so that the first nut members 272 will not be loosened during operation, thereby effectively preventing the first running wheel 23 from being loosened during operation.

[0063] Furthermore, in order to facilitate the assembly operation of the support shaft 26, the bearing 273, the first travel wheel 23, etc., the improved wire saw machine 100 further includes a second nut member 29; one end of the support shaft 26 passes through the movable outer frame 21 and is locked and connected with the movable outer frame 21 through the fixing plate 261, that is, the fixing plate 261 is fixedly connected to one end of the support shaft 26, and the fixing plate 261 and the movable outer frame 21 are locked and connected by bolts or screws; the other end of the support shaft 26 passes through the movable outer frame 21 and is formed with a second external thread section 262, and the other end of the support shaft 26 is locked on the movable outer frame 21 by the second nut member 29, that is, the second nut member 29 is screwed on the second external thread section 262, and the second nut member 29 is pressed against the outer wall of the movable outer frame 21. In the specific implementation of the present invention, at least two second nut members 29 can be arranged outside the second external thread section 262 to better lock the other end of the support shaft 26 on the movable outer frame 21.

[0064] In some embodiments of the present invention, the surface of the first running wheel 23 is provided with a first V-shaped groove 231, and the surface of the lifting guide protrusion 11 is formed with a V-shaped guide surface (not shown) matched with the first V-shaped groove, and the V-shaped guide surface is in contact with the groove wall of the first V-shaped groove 231. The present invention has at least the following beneficial effects by designing the first running wheel 23 and the lifting guide protrusion 11 to cooperate with each other using the first V-shaped groove 231 and the V-shaped guide surface: 1.

As a specific embodiment of the present invention, the first square tube 12 and the second square tube 13 are square tubes with equal side lengths, so that during the specific manufacturing, only square tubes of the same specification need to be used, which makes the manufacturing more convenient, and can ensure that the structure between the support column 1 and the lifting mechanism 2 is more compact, while keeping the lifting guide protrusions 11 on both sides of the support column 1 symmetrical, which helps to further improve the stability of the lifting; the movable outer frame 21 is a rectangular outer frame that is closed on all sides and has openings at the top and bottom, which is convenient for movably mounting the movable outer frame 21 on the outside of the support column 1, and enables the first running wheels 23 in the movable outer frame 21 to more reliably hold the support column 1, while also making the overall structure more compact and beautiful; in addition, the two first running wheels 23 are respectively located on both sides of the support column 1, and will not be interfered with by the connecting piece 14 between the first square tube 12 and the second square tube 13.

[0067] More specifically, the first square tube 12 has a third angle 124 facing the second square tube 13, and a fifth side 125 and a sixth side 126 forming the third angle 124; the second square tube 13 has a fourth angle 134 facing the first square tube 12, and a seventh side 135 and an eighth side 136 forming the fourth angle 134; at the same time, since the first square tube 12 and the second square tube 13 are both square tubes, a fifth angle 127 is formed between the first side 122 and the fifth side 125, and a sixth angle 128 is formed between the second side 123 and the sixth side 126; a seventh angle 137 is formed between the third side 132 and the seventh side 135, and an eighth angle 138 is formed between the fourth side 133 and the eighth side 136;

[0068] An assembly space 15 is formed between the third angle 124 and the fourth angle 134, and the screw rod 22 is installed in the assembly space 15. By forming the assembly space 15 between the third angle 124 and the fourth angle 134 and installing the screw rod 22 in the assembly space 15, the present invention can, on the one hand, make the screw rod 22 in the middle position of the entire support column 1, so as to more stably drive the movable outer frame 21 to be raised and lowered; on the other hand, it is convenient to hide the screw rod 22, and make the structure of the entire support column 1 more concise and beautiful.

[0069] The fifth side 125 and the seventh side 135 are located on the back side of the supporting column 1, and the back side of the supporting column 1 refers to the side facing away from the flywheel mechanism 3, and a connecting seat 25 is arranged between the fifth side 125 and the seventh side 135, one end of the connecting seat 25 is fixedly connected to the movable outer frame 21, and the other end of the connecting seat 25 is threadedly connected to the screw rod 22, so that when the screw rod 22 rotates, the connecting seat 25 can drive the movable outer frame 21 to perform lifting movement together, thereby driving the flywheel mechanism 3 and the rope saw blade to perform lifting movement; when the present invention is implemented, two connecting seats 25 can be arranged between the fifth side 125 and the seventh side 135 of each supporting column 1, and one of the connecting seats 25 is connected to the upper end inside the movable outer frame 21, and the other connecting seat 25 is connected to the lower end inside the movable outer frame 21, so as to ensure that the screw rod 22 can be reliably connected to the movable outer frame 21.

[0070] The first angle 121, the second angle 131, the third angle 124 and the fourth angle 134 are all rounded corners, and a rounded corner avoidance groove 235 is formed on the first walking wheel 23 at the position corresponding to the rounded corner, and the rounded corner avoidance groove 235 is used to avoid the rounded corner, thereby ensuring that the V-shaped guide surface can reliably fit with the groove wall of the first V-shaped groove 231; the angular bisectors of the first angle 121, the second angle 131, the third angle 124 and the fourth angle 134 are on the same straight line to ensure that the lifting guide protrusions 11 located on both sides of the support column 1 are symmetrical, which helps to make the movable outer frame 21 able to be lifted and lowered more smoothly.

[0071] The present invention designs a support column 1 including a first square tube 12, a second square tube 13 and a connecting piece 14, and connects the first square tube 12 and the second square tube 13 together through the connecting piece 14 to form a whole, and directly forms a lifting guide protrusion 11 by using the edges and corners of the first square tube 12 and the second square tube 13; since various square tubes already exist in the prior art, by adopting the technical solution of the present invention, it is convenient to directly use the existing square tubes to manufacture the support column 1 without the need to specially open the mold and manufacture the support column 1, so that the manufacturing of the entire support column 1 is simpler and more convenient, and the manufacturing cost is lower; at the same time, the structure of the entire support column 1 is very simple, and the assembly operation between the support column 1 and the lifting mechanism 2 is also very simple and fast to install, which can improve the equipment installation efficiency.

[0072] More specifically, in order to reliably combine the first square tube 12 and the second square tube 13, the connecting member 14 includes an upper connecting plate 141, a lower connecting plate 142 and a middle connecting plate 143;

[0073] The upper ends of the first square tube 12 and the second square tube 13 are connected to the upper connecting plate 141, and the lower ends of the first square tube 12 and the second square tube 13 are connected to the lower connecting plate 142; the sixth side 126 of the first square tube 12 and the eighth side 136 of the second square tube 13 are connected through a plurality of middle connecting plates 143, and a recessed portion 1431 is formed on the middle connecting plate 143 at a position corresponding to the assembly space 15, so that the middle connecting plate 143 will not affect the rotation of the screw rod 22.

[0074] When the present invention is implemented, in order to further improve the supporting strength of the supporting column 1, the improved wire saw machine 100 also includes a supporting beam 4, an auxiliary supporting frame 5 and a supporting platform (not shown); the two ends of the supporting beam 4 are respectively connected to the upper connecting plates 141 at the upper ends of the two supporting columns 1, and the lower connecting plates 142 at the lower ends of the two supporting columns 1 are connected to the supporting platform; the back of each of the supporting columns 1 is equipped with an auxiliary supporting frame 5, and the upper end of the auxiliary supporting frame 5 is connected to the supporting beam 4, and the lower end of the auxiliary supporting frame 5 is connected to the supporting platform.

[0075] In some embodiments of the present invention, two first traveling wheels 23 are provided in the movable outer frame 21 corresponding to each of the lifting guide protrusions 11, and each of the first traveling wheels 23 is rotatably connected to the movable outer frame 21 through a supporting shaft 26. In specific implementation, one of the first traveling wheels 23 can be set at the upper end of the movable outer frame 21, and the other first traveling wheel 23 can be set at the lower end of the movable outer frame 21; in this way, only four first traveling wheels 23 need to be provided on both sides of each supporting column 1. Therefore, compared with the existing rope saw machine in which each supporting column needs to be provided with 8 cylindrical rollers and a number of auxiliary wheels, the overall structure can be effectively simplified and the overall cost can be reduced.

[0076] In some embodiments of the present invention, a dust cover 6 is provided on the front of the support column 1, and the front of the support column 1 refers to the side facing the flywheel mechanism 3. Since the support column 1 is provided with a screw rod 22 between the first square tube 12 and the second square tube 13, by providing the dust cover 6 on the front of the support column 1, a dustproof effect can be achieved, so that dust is not easily attached to the screw rod 22.

[0077] In some embodiments of the present invention, please refer to Figures 10 to 12 As shown, the improved wire saw machine 100 further includes a guide wheel mechanism 7 disposed on the movable outer frame 21;

[0078] The guide wheel mechanism 7 includes a guide wheel assembly 71, a support outer frame 72, a support beam 73, a travel track 74, a second travel wheel 75 and a second drive assembly 76;

[0079] The guide wheel assembly 71 is connected to one end of the support beam 73, so that the support beam 73 can drive the guide wheel assembly 71 to move; the support outer frame 72 is fixed to the front side of the movable outer frame 21, the support beam 73 passes through the support outer frame 72, the walking track 74 is arranged on the support beam 73 along the length direction, the second walking wheel 75 is rotatably arranged in the support outer frame 72, and the second walking wheel 75 is movably arranged on the walking track 74; the second driving assembly 76 is connected to the support beam 73, and the support beam 73 is driven by the second driving assembly 76 to drive the guide wheel assembly 71 to move, so as to adjust the position of the guide wheel assembly 71; wherein, the guide wheel assembly 71 is a component that all existing rope saw machines need to use, and its specific structure is well known to those skilled in the art, so the present invention will not elaborate on the guide wheel assembly 71 in detail.

[0080] As for the guide wheel assembly 71, the existing rope saw machines all use the guide column and the screw rod to drive the guide wheel assembly 71 to move, which has the problem that the overall structure is relatively complex and the cost is high, and the guide column is easy to get stuck due to surface wear and rust after being used for a period of time, making it difficult for the screw rod to smoothly push the guide wheel assembly 1 to move, thereby causing the problem that the entire guide wheel mechanism is easy to deform and damage. However, the present invention uses the travel track 74 and the second travel wheel 75 to drive the guide wheel assembly 71 to move, which not only makes the structure of the entire guide wheel mechanism simpler, more convenient to install, and lower in cost, but also even if the travel track 74 is worn and rusted on the surface, the rolling effect on the second travel wheel 75 is also very small, and the guide wheel mechanism 7 will not be deformed or damaged, thereby helping to improve the service life of the entire guide wheel mechanism 7.

[0081] More specifically, the top and bottom of the support beam 73 are provided with the walking tracks 74, and at least two second walking wheels 75 are movably provided on each of the walking tracks 74; the surface of the second walking wheel 75 is ringed with a second V-shaped groove 751, and a V-shaped track surface 741 matching the second V-shaped groove 751 is formed on the walking track 74.

[0082] The present invention arranges travel tracks 74 at the top and bottom of the support beam 73, and each travel track 74 is equipped with at least two second travel wheels 75. At the same time, the second travel wheel 75 is designed to have a second V-shaped groove 751, and the travel track 74 has a V-shaped track surface 741 that matches the second V-shaped groove 751. This can ensure the stability of the support beam 73 and the guide wheel assembly 1 during movement, and is not prone to shaking or swaying, thereby helping to improve processing accuracy.

[0083] More specifically, the second driving assembly 76 includes a rack 761, a driving motor 762 and a driving gear 763; the rack 761 is arranged on the support beam 73 along the length direction; the driving motor 762 is arranged on the supporting outer frame 72, the driving gear 763 is connected to the output shaft of the driving motor 762, and the driving gear 763 is meshed with the rack 761. When working, the driving motor 762 can be used to drive the driving gear 763 to rotate. Since the rack 761 is arranged on the support beam 73 along the length direction, under the action of the driving gear 763, the rack 761 can drive the support beam 73 to move and adjust; and in specific use, the forward and reverse rotation of the driving motor 762 can be used to drive the support beam 73 forward and backward, thereby driving the guide wheel assembly 71 to move forward and backward.

[0084] More specifically, the rack 761 is disposed on one side of the bottom of the support beam 73. By disposing the rack 761 at the bottom of the support beam 73, dust adhering to the rack 761 and the driving gear 763 during operation can be reduced, so that the driving gear 763 can better drive the rack 761 to drive the support beam 73 to move.

[0085] Although the specific implementation modes of the present invention are described above, those skilled in the art should understand that the specific implementation modes described are only illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included in the scope of protection of the claims of the present invention.
