Description

Technical Field

[0001] This invention relates to the technical field of stone processing equipment, and in particular to a bridge-type stone cutting machine. Background Technology

[0002] Stone cutting machines are used to process quarried stone into slabs. When cutting stone, it is essential to keep the saw blade moving smoothly to avoid instability such as blade deviation, shaking, or jumping, in order to achieve a smooth cut surface and high cutting efficiency. However, when traditional stone slicing processing uses stone saws to cut large stones, the saw blade assembly consists of multiple large saw blades. This heavy and bulky assembly still struggles to effectively overcome instability issues such as shaking and jumping under high-intensity and high-speed operation. The saw blade cannot cut smoothly back and forth on the same horizontal plane, resulting in poor flatness of the stone cut surface, poor cutting quality, low cutting efficiency, and easy deformation and damage of the saw blade, ultimately affecting the overall cutting performance.

[0003] Currently available bridge-type stone cutting machines include two side beams, two crossbeams mounted on the side beams, a middle frame passing through the two crossbeams, and a saw blade cutting assembly located on one side of the middle frame. The two crossbeams can move back and forth on the side beams, and the middle frame moves left and right on the two crossbeams, driving the saw blade cutting assembly to move left and right to cut the stone. The saw blade cutting assembly also moves up and down on one side of the middle frame to cut the stone. However, existing bridge-type stone cutting machines have the following drawbacks:

[0004] 1. To ensure the smooth lateral movement of the middle frame on the two crossbeams, driving the saw blade to cut the stone, existing bridge-type stone cutting machines require improved structural strength and load-bearing capacity of the crossbeams and middle frame. Since the stone to be cut is very large, a large stone cutting machine is needed, necessitating the lengthening of the crossbeams to assemble the saw blade cutting assembly. However, lengthening the crossbeams reduces their overall structural strength and load-bearing capacity. Furthermore, because the large and heavy saw blade cutting assembly is located on one side of the middle frame, the two crossbeams experience different stresses during stone cutting; the crossbeam closer to the saw blade cutting assembly experiences greater stress, while the one farther away experiences less. Additionally, the partition in the middle frame creates two through holes for the two crossbeams to pass through, resulting in uneven stress on both sides of the middle frame, and the structure of the partition assembled within the middle frame is relatively unstable. Ultimately, this leads to weak structural strength and load-bearing capacity of the crossbeams and middle frame, resulting in poor cutting stability.

[0005] 2. Each crossbeam is equipped with a linear guide rail and a rack parallel to the linear guide rail. The inner top surface of each through hole is equipped with a linear guide rail seat parallel to the linear guide rail, a linear guide rail slider located on the bottom surface of the linear guide rail seat and slidingly engaged with the linear guide rail, and a gear meshing with the rack. Each gear is driven by a motor to rotate and mesh with the rack, moving the middle frame left and right on the crossbeam. When the middle frame and the two crossbeams move and cooperate, two motors, two sets of gears and racks, as well as two sets of linear guide rail seats, linear guide rail sliders, and linear guide rail components are required. The assembly of the components is large and the space of the through hole is small. The assembly structure of the linear guide rail seat, linear guide rail slider, linear guide rail, gears, and racks is complicated and inconvenient to assemble, resulting in high cost of cutting equipment. Moreover, the two motors drive two sets of gears and racks respectively, which may cause asynchronous driving problems, resulting in asynchronous forward and backward movement of the middle frame, tilting and deviation of the saw blade, and failure to achieve the goal of a flat cutting surface and high cutting efficiency.

[0006] 3. In existing bridge-type stone cutting machines, the horizontal movement of the middle frame is limited by a structure consisting of a linear guide seat, a linear guide slider, and a linear guide. The linear guide seat is locked to the bottom surface of the top plate of the middle frame, and the linear guide is locked to the crossbeam. Because the bottom surface of the top plate of the middle frame is located on the inside, its levelness cannot be guaranteed during production. Therefore, during assembly, the linear guide seat is directly locked to the middle frame by positioning bolts. This locking structure is prone to unevenness at both ends of the linear guide seat, and the narrow assembly space makes it difficult to adjust. The difference in verticality and horizontality of the linear guide seat results in poor assembly accuracy between the linear guide slider and the linear guide, making it impossible to move horizontally smoothly. The saw blade will jump up and down, resulting in poor cutting stability and low cutting efficiency.

[0007] In view of this, the inventor, in order to address the numerous shortcomings and inconveniences caused by the imperfect structural design of the aforementioned stone cutting machine, has conceived and actively researched and improved the design to develop this invention. Summary of the Invention

[0008] The purpose of this invention is to provide a bridge-type stone cutting machine with strong crossbeams and middle frames, high load-bearing capacity, and simple assembly structure. During high-speed and high-power cutting, it can maintain cutting stability and avoid phenomena such as saw blade shaking, jumping, trembling, and deviation. The overall cutting performance is high, the cutting surface is flatter, and the cutting efficiency is higher.

[0009] To achieve the above objectives, the solution of the present invention is:

[0010] A bridge-type stone cutting machine includes two side beams, a crossbeam slidably mounted on the two side beams at both ends, a middle frame passing through the crossbeams, and a saw blade cutting assembly mounted on the middle frame. The crossbeams have two parallel first support beams and a second support beam, the two first support beams being connected together by multiple connecting rods, and the second support beam being mounted above the connecting rods. Linear rails are respectively mounted on the two first support beams, and a rack is mounted on the second support beam. The two linear rails and the rack are parallel to each other in the extension direction of the crossbeam. The middle frame is integrally formed, and the inner top surface of the middle frame is provided with two linear rail seats that are parallel to the two linear rails vertically, a linear rail slider mounted on the bottom surface of the linear rail seats and slidingly engaged with the linear rails, and a gear meshing with the rack. The gear is driven by a first drive mechanism mounted on the top surface of the middle frame to rotate and mesh with the rack, moving the middle frame left and right on the crossbeam.

[0011] The first support beam is provided with a rail assembly base for assembling the rail, and the second support beam is provided with a rack assembly base for assembling the rack. The two rail assembly bases and rack assembly bases are arranged in parallel.

[0012] The longitudinal height of the two linear guide assembly bases on the crossbeam is higher than that of the rack assembly base on the crossbeam.

[0013] The first support beam has a bottom side plate and four first side plates extending upward from the four sides of the bottom side plate. A first assembly plate is provided on the upper part of the space enclosed by the four first side plates. The linear guide assembly base is formed on the first assembly plate. The highest position of the first side plate protrudes above the first assembly plate, and the four first side plates surround the mating structure formed by the linear guide and the linear guide slider. The second support beam has a second assembly plate abutting against the connecting rod and four second side plates extending upward from the four sides of the second assembly plate. The rack assembly base is formed on the second assembly plate, and the four second side plates surround the mating structure formed by the rack and the gear.

[0014] The connecting rod is a rectangular tube; the connecting rod has a first connecting rod and a second connecting rod spaced apart, the width of the first connecting rod being smaller than the width of the second connecting rod.

[0015] The middle frame has a top plate, a bottom plate, and two side plates. The top plate of the middle frame is provided with a set of limiting mechanisms for each rail seat. Each set of limiting mechanisms has two rows of multiple limiting holes that are equally spaced in the extension direction of the crossbeam, multiple equal-height blocks that are respectively set in each limiting hole, and multiple first bolts that pass through the equal-height blocks and are locked onto the rail seat. The bottom end of the equal-height block extends out of the limiting hole and abuts against the rail seat.

[0016] The contour block has a vertical part extending into the limiting hole and a horizontal ring platform mounted on the top surface of the middle frame top plate. The vertical part is provided with a first through hole corresponding to the limiting hole. A first bolt passes through the first through hole and is locked to the rail seat. The bottom end of the vertical part extends out of the bottom end of the limiting hole and abuts against the rail seat. The middle frame top plate is provided with a plurality of first countersunk holes surrounding the circumference of the limiting hole. The horizontal ring platform is provided with a second through hole corresponding to the first countersunk hole. A second bolt passes through the second through hole and is locked in the first countersunk hole to lock the contour block to the middle frame top plate.

[0017] The top plate of the middle frame is also provided with a set of positioning mechanisms for each rail seat. Each set of positioning mechanisms has at least two positioning holes located on the center line between the two rows of limiting holes and multiple third bolts that pass through the positioning holes and are locked onto the rail seat. The top plate of the middle frame is provided with multiple second countersunk holes surrounding the circumference of the positioning holes. The third bolt has a screw part that locks into the positioning hole and a nut part that is mounted on the top plate of the middle frame. The nut part is provided with a third through hole corresponding to the second countersunk hole. The third bolt passes through the positioning hole and is locked onto the rail seat. A fourth bolt passes through the third through hole and is locked into the second countersunk hole to lock the third bolt onto the top plate of the middle frame.

[0018] The bottom surface of the top plate of the middle frame is provided with intersecting ribs; and the front and rear ends of the top plate of the middle frame extend outward and protrude from the end faces of the side plates of the middle frame. Reinforcing plates are provided between the front and rear ends of the top plate of the middle frame and the two side plates of the middle frame, respectively. The reinforcing plates have a first straight edge connected to the top plate of the middle frame, a second straight edge connected to the side plates of the middle frame, and an inclined edge connecting the first and second straight edges. The bottom plate of the middle frame is provided with intersecting reinforcing grids. The inner side surface of the side plate of the middle frame is provided with two reinforcing structures at the top and bottom. The reinforcing structures have rectangular grooves recessed into the inner side surface of the side plate of the middle frame and two connecting reinforcing ribs distributed along the diagonal of the rectangular grooves.

[0019] Two sleeves are respectively provided on the outer sides of the two middle frame side plates. Guide posts are respectively fitted inside the four sleeves. A first plate is provided at the top of the four guide posts and a second plate is provided at the bottom of the four guide posts. A first vertical gear protruding from the middle frame side plates and a second drive mechanism driving the first vertical gear to rotate are provided above the top plate of the middle frame. A column is locked on one side of the second plate. A first vertical rack that meshes with the first vertical gear is provided on the column. A clearance slot is provided on the first plate for the column to move up and down to make room. The saw blade cutting assembly is provided on one side of the second plate. The second drive mechanism drives the first vertical gear to rotate and mesh with the first vertical rack to move up and down, thereby moving the first plate and the second plate up and down, and in turn driving the saw blade cutting assembly to move up and down to cut the stone.

[0020] With the above structure, the crossbeam and middle frame of the bridge-type stone cutting machine of this invention have high structural strength, high load-bearing capacity, and simple assembly structure. During high-speed, high-force cutting, it can maintain cutting stability, avoiding saw blade shaking, jumping, vibrating, and deviation. Overall cutting performance is high, the cut surface is smoother, and cutting efficiency is higher. The bridge-type stone cutting machine of this invention has the following advantages:

[0021] 1. The crossbeam of this invention is composed of two first beams connected by connecting rods to form a whole. The two first beams not only restrict the parallel setting of the two rails, allowing the middle frame to move horizontally and smoothly, but also eliminate the need for leveling the two rails and rack during assembly, making assembly more convenient. Moreover, the multiple connecting rods enhance the structural strength and load-bearing capacity of the crossbeam when it is lengthened, preventing a decrease in structural strength and load-bearing capacity due to lengthening. The two first beams are connected together to distribute the force, and the force on the first beam closer to the saw blade cutting assembly can be distributed to the first beam farther away from the saw blade cutting assembly, making the force on the two first beams more balanced, further improving the overall structural strength and load-bearing capacity of the crossbeam. The middle frame is integrally cast, resulting in stronger structural strength and more balanced force distribution. The middle frame moves smoothly on the crossbeam, driving the saw blade cutting assembly to move smoothly to cut the stone, resulting in better cutting stability. This avoids the problem of weak structural strength and low load-bearing capacity of the two crossbeams and middle frame when used together in existing double crossbeams and middle frames, which affects the stability of movement.

[0022] 2. The two sets of linear rails and linear rail sliders of the present invention are driven to slide by the gears and racks of the first driving mechanism. This not only makes the two sets of linear rails and linear rail sliders move synchronously, but also ensures that the middle frame moves more smoothly and steadily, thereby driving the saw blade cutting assembly to move horizontally and smoothly to cut the stone, resulting in a flatter cut surface and higher cutting efficiency; it also reduces the setting of the driving mechanism, simplifies the assembly structure, and reduces equipment costs.

[0023] 3. The strong structural strength and high load-bearing capacity of the crossbeam and middle frame of the present invention make the two structures work together better, which can improve the verticality and horizontality of the two sets of linear guides, linear guide sliders and linear guide seats, and the assembly accuracy is high. During high-speed and high-force cutting, it can maintain cutting stability and avoid the saw blade from shaking, jumping, vibrating and deviating. The overall cutting performance is high, the cutting surface is flatter and the cutting efficiency is higher. Attached Figure Description

Detailed Implementation

[0045] To further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0046] Please see Figures 1 to 16This invention discloses a bridge-type stone cutting machine, comprising two side beams 10, a crossbeam 1 slidably mounted on the two side beams 10 at both ends, a middle frame 2 passing through the crossbeam 1, and a saw blade cutting assembly 20 mounted on the middle frame 2; the crossbeam 1 has two parallel first support beams 11 and a second support beam 12, the two first support beams 11 being connected together by multiple connecting rods 13, and the second support beam 12 being mounted above the connecting rods 13; linear guides 14 are respectively mounted on the two first support beams 11, and the second support beam... 12 is provided with a rack 15, and the two linear rails 14 and the rack 15 are parallel to each other in the extension direction of the crossbeam 1; the middle frame 2 is integrally formed, and the inner top surface of the middle frame 2 is provided with two linear rail seats 21 that are parallel to the two linear rails 14 respectively, a linear rail slider 22 that is provided on the bottom surface of the linear rail seat 21 and slides with the linear rail 14, and a gear 23 that meshes with the rack 15. The gear 23 is driven by the first driving mechanism 3 provided on the top surface of the middle frame 2 to rotate and mesh with the rack 15 and move, causing the middle frame 2 to move left and right on the crossbeam 1.

[0047] The crossbeam 1 and middle frame 2 of this invention's bridge-type stone cutting machine have high structural strength, high load-bearing capacity, and simple assembly structure. During high-speed, high-force cutting, they maintain cutting stability, avoiding saw blade shaking, jumping, vibrating, and deviation. Overall, the cutting performance is high, the cut surface is smoother, and the cutting efficiency is higher. This bridge-type stone cutting machine has the following advantages:

[0048] 1. The crossbeam 1 of this invention is composed of two first support beams 11 connected by connecting rods 13 to form a whole. The two first support beams 11 not only restrict the parallel arrangement of the two linear rails 14, allowing the middle frame 2 to move horizontally and smoothly; but also eliminate the need to adjust the level of the two linear rails 14 and the rack 15 during assembly, making assembly more convenient; moreover, the multiple connecting rods 13 strengthen the structural strength and load-bearing capacity of the crossbeam 1 when it is lengthened, preventing the crossbeam 1 from reducing its structural strength and load-bearing capacity due to lengthening; the two first support beams 11 are connected together to distribute the force, close to the saw blade cutting assembly 20. The force on the first beam 11 can be distributed to the first beam 11 away from the saw blade cutting assembly 20, making the force on the two first beams 11 more balanced, and further improving the overall structural strength and load-bearing capacity of the crossbeam 1; the middle frame 2 is integrally cast, and the middle frame 2 has stronger structural strength and more balanced force. The middle frame 2 moves smoothly on the crossbeam 1, driving the saw blade cutting assembly 20 to move smoothly to cut the stone, resulting in better cutting stability; this can avoid the situation where the two crossbeams and the middle frame are weak in structural strength and have low load-bearing capacity, which affects the stability of movement when the existing double crossbeams and middle frame are used together;

[0049] 2. The two sets of linear rails 14 and linear rail sliders 22 of the present invention are driven to slide by the gears 23 and racks 15 transmitted by the first driving mechanism 3. This not only makes the two sets of linear rails 14 and linear rail sliders 22 move synchronously, but also ensures that the middle frame 2 moves more smoothly and steadily, thereby driving the saw blade cutting assembly 20 to move horizontally and smoothly to cut the stone, resulting in a flatter cutting surface and higher cutting efficiency; it also reduces the number of driving mechanisms, simplifies the assembly structure, and reduces equipment costs.

[0050] 3. The crossbeam 1 and the middle frame 2 of the present invention have strong structural strength and high load-bearing capacity, which makes the cooperation structure of the two better. It can improve the verticality and horizontality of the cooperation structure of the two sets of linear rails 14, linear rail sliders 22 and linear rail seats 21, and the assembly accuracy is high. During high-speed and high-force cutting, it can maintain cutting stability and avoid the saw blade from shaking, jumping, vibrating and deviating. The overall cutting performance is high, the cutting surface is flatter, and the cutting efficiency is higher.

[0051] The first support beam 11 of the present invention is provided with a rail assembly base 111 for assembling the rail 14, and the second support beam 12 is provided with a rack assembly base 121 for assembling the rack 15. The two rail assembly bases 111 and rack assembly bases 121 are arranged in parallel. This can restrict the parallel arrangement of the two rails 14 and the rack 15, eliminating the need for parallel adjustment during assembly and making assembly more convenient. The longitudinal height of the two rail assembly bases 111 on the crossbeam 1 is higher than the longitudinal height of the rack assembly base 121 on the crossbeam 1 (that is, the longitudinal height of the rail 14 and rail slider 22 mating structure is higher than the longitudinal height of the gear 23 and rack 15 mating structure), so that the two rails 14 and rack 15 are located on the three parallel sides of the triangular prism, forming a triangular stability structure. This ensures high verticality and horizontality of the rail 14 and rail slider 22, gear 23 and rack 15 mating structures, resulting in high assembly accuracy. This makes the horizontal movement of the middle frame 2 and the crossbeam 1 more stable, improving the overall cutting performance.

[0052] The first support beam 11 of the present invention has a bottom side plate 112 and four first side plates 113 extending upward from the four sides of the bottom side plate 112. A first assembly plate 114 is provided on the upper part of the space enclosed by the four first side plates 113. The linear guide assembly base 111 is formed on the first assembly plate 114. The highest position of the first side plate 113 protrudes above the first assembly plate 114, and the four first side plates 113 surround the mating structure formed by the linear guide 14 and the linear guide slider 22. The second support beam 12 has a second assembly plate 122 abutting against the connecting rod 13 and four second side plates 123 extending upward from the four sides of the second assembly plate 122. The rack assembly base 121 is formed on the second assembly plate 122, and the four second side plates 123 surround the mating structure formed by the rack 15 and the gear 23.

[0053] In this invention, the longitudinal position of the first assembly plate 114 is higher than that of the second assembly plate 122, so that the two linear guides 14 and the rack 15 are located on the three parallel sides of the triangular prism, forming a triangular stability structure, and the middle frame 2 moves smoothly on the crossbeam 1, resulting in better cutting stability.

[0054] The connecting rod 13 of the present invention is a rectangular tube, which can strengthen the structural strength of the connecting rod 13, thereby strengthening the structural strength and load-bearing capacity of the crossbeam 1 and improving cutting stability. The connecting rod 13 has a first connecting rod 131 and a second connecting rod 132 arranged at intervals. The width of the first connecting rod 131 is smaller than the width of the second connecting rod 132. Connecting rods 13 with different widths can make the structural strength of the crossbeam 1 better. The connecting rods 13 located at both ends of the first support beam 11 are the first connecting rods 131. Furthermore, a reinforcing connecting plate 133 is provided in the middle of the interior of the connecting rod 13 to strengthen the structural strength of the connecting rod 13.

[0055] The first support beam 11 of the present invention has a reinforcing partition plate 115 in the middle of the four first side plates 113, and the bottom side plate 112 and the first side plate 113 connected to the connecting rod 13 are respectively provided with a plurality of rectangular holes; the reinforcing partition plate 115 can enhance the structural strength and load-bearing capacity of the first support beam 11, and has good cutting stability and high cutting efficiency.

[0056] In this invention, the two first support beams 11 of the crossbeam 1 are respectively supported and fixed at both ends by two sliding seats 101, and the sliding seats 101 are slidably disposed on the side beam 10; the crossbeam 1 slides smoothly on the side beam 10, driving the saw blade cutting assembly 20 to move back and forth.

[0057] The middle frame 2 of the present invention has a top plate 211, a bottom plate 212, and two side plates 213. The top plate 211 is provided with a set of limiting mechanisms 4 corresponding to each rail seat 21. Each limiting mechanism has two rows of multiple limiting holes 41 evenly spaced along the extension direction of the crossbeam 1, multiple equal-height blocks 42 respectively disposed within each limiting hole 41, and multiple first bolts 43 passing through the equal-height blocks 42 and locked onto the rail seat 21. The bottom end of each equal-height block 42 extends out of the limiting hole 41 and abuts against the rail seat 21. A leveling block 42 is provided inside the limiting hole 41. The leveling block 42 ensures that the bottom of the leveling block 42 is on the same horizontal plane, which makes the verticality and horizontality of the rail seat 21 after it is assembled into the middle frame 2 high, thereby improving the assembly accuracy between the rail slider 22 and the rail 14. There is no need to adjust the verticality and horizontality of the rail seat 21 during assembly, making assembly more convenient. During cutting, the saw blade will not jump up and down, and the saw blade cutting assembly 20 can move horizontally smoothly to cut the stone, resulting in high cutting stability, a smoother cutting surface, and high cutting efficiency.

[0058] The equalizing block 42 of the present invention has a vertical part 421 extending into the limiting hole 41 and a transverse ring platform 422 mounted on the top surface of the middle frame top plate 211. The vertical part 421 is provided with a first through hole 4211 corresponding to the limiting hole 41. A first bolt 43 passes through the first through hole 4211 and is locked to the rail seat 21. The bottom end of the vertical part 421 extends out of the bottom end of the limiting hole 41 and abuts against the rail seat 21. The first bolt 43 passes through the first through hole 4211 and is locked to the rail seat 21, which not only firmly locks the middle frame 2, the equalizing block 42 and the rail seat 21 together, but also... The setting of the leveling block 42 improves the verticality and horizontality of the rail seat 21, resulting in high precision in the fit between the rail seat 21, the rail slider 22, and the rail 14. This makes the middle frame 2 move more smoothly and steadily on the crossbeam 1, improving cutting performance. It also avoids unevenness at both ends of the rail seat 21, ensuring better stability of the middle frame 2 on the crossbeam 1. The vertical part 421 of the leveling block 42 passes through the limiting hole 41. The wall of the limiting hole 41 protects the vertical part 421 of the leveling block 42 and restricts the vertical part 421 to remain vertical, effectively improving the horizontality of the rail seat 21.

[0059] The top plate 211 of the middle frame of the present invention is provided with a plurality of first countersunk holes 44 surrounding the circumference of the limiting hole 42. The transverse ring platform 422 is provided with a second through hole 4221 corresponding to the first countersunk hole 44. The second bolt 45 passes through the second through hole 4221 and is locked in the first countersunk hole 44 to lock the level block 42 on the top plate 211 of the middle frame.
