Description

Technical Field

[0001] The utility model relates to the technical field of stone processing equipment, in particular to a crossbeam structure of a bridge-type stone cutter. Background Art

[0002] The existing stone cutter is a machine for processing the stone from the mine in sheets. When cutting the stone, the saw blade should be kept moving steadily to cut the stone, and the saw blade should be avoided from deviating, shaking, jumping and other unstable problems, so as to achieve the purpose of smooth cutting surface and high cutting efficiency. However, when the traditional stone slicing processing adopts the stone cutter to cut large stones, since a plurality of large saw blades are assembled on the saw blade cutting assembly, the very heavy and large saw blade cutting assembly is still difficult to effectively overcome the unstable problems such as shaking and jumping in high-intensity and high-speed operation. The saw blade cannot cut back and forth steadily on the same horizontal plane, the flatness of the stone cutting surface is poor, the cutting quality is poor and the cutting efficiency is low, and the saw blade is easily deformed and damaged, which ultimately affects the overall cutting performance.

[0003] The bridge-type stone cutters currently available on the market include two side beams, two cross beams arranged on the two side beams, a middle frame passing through the two cross beams, and a saw blade cutting assembly arranged on one side of the middle frame.

Among them, the two cross beams on the existing stone cutter are welded together by multiple connecting rods to ensure that the two cross beams are arranged in parallel, so that the saw blade cutting assembly Move left and right smoothly to cut the stone; the end face of the connecting rod is against the side of the beam, and then the end face of the connecting rod is welded to the side of the beam by welding; however, in this welding structure, the welding surface of the beam and the connecting rod is a plane, that is, the connection surface of the two is a vertical plane. When the beam is subjected to force, the force is concentrated on the welding surface, which is prone to loosening and breaking, reducing the overall structural strength and bearing capacity of the beam, the saw blade cutting assembly has poor cutting stability, cannot move smoothly horizontally, the saw blade will jump up and down, and the cutting efficiency is low.

[0004] In view of this, the designer has conducted in-depth research and actively studied and improved the design to develop and design this case in view of the many deficiencies and inconveniences caused by the imperfect design of the crossbeam structure of the above-mentioned stone cutter.

Detailed Embodiment

[0028] In order to further explain the technical solution of the present utility model, the present utility model will be elaborated in detail below through specific embodiments.

[0029] Please refer to Figures 1 to 8, the present utility model discloses a crossbeam structure of a bridge-type stone cutting machine. The crossbeam structure has two first support beams 11 arranged in parallel and a second support beam 15. The two first support beams 11 are connected together by a plurality of connecting rods 12, and the second support beam 15 is erected above the connecting rods 12; linear guides 14 are respectively arranged on the two first support beams 11, and a rack 16 is arranged on the second support beam 15. The two linear guides 14 and the rack 15 are parallel to each other in the extending direction of the crossbeam; each of the first support beams 11 has an inner side plate 111 and an outer side plate 112 arranged in parallel. A plurality of through holes 1111 for the plurality of connecting rods 12 to pass through are arranged on the inner side plate 111, and at least one slot 1121 is arranged on the outer side plate 112 corresponding to each connecting rod 12; both ends of each connecting rod 12 are respectively provided with an abutting portion 121 abutting against the inner side surface of the outer side plate 112 and a plugging portion 122 plugged into the slot 1121 of the corresponding outer side plate 112, and welding fixation is performed at the connection between the abutting portion 121 and / or the plugging portion 122 and the outer side plate 112.

[0030] When the two first support beams 11 and the connecting rod 12 of the bridge-type stone cutting machine of the utility model are assembled and fixed, first, both ends of the connecting rod 12 respectively pass through the through holes 1111 of the inner side plates 111 of the two first support beams 11. Secondly, the insertion part 122 of the connecting rod 12 is inserted into the slot 1121 of the outer side plate 112 of the first support beam 11, and the abutting part 121 abuts against the inner side surface of the outer side plate 112 of the first support beam 11. Then, welding and fixing are carried out at the connection between the abutting part 121 and / or the insertion part 122 and the outer side plate 112. Finally, the second support beam 15 is erected above the connecting rod 12. The second support beam 15 is provided with a rack 16. Two linear guides 14 are respectively arranged on the first support beams 11. The two linear guides 14 and the rack 16 are parallel to each other in the extending direction of the cross beam 1. Among them, the two first support beams 11 and the plurality of connecting rods 12 are fixed together by two methods of insertion and welding, so that the connection structure between the first support beam 11 and the connecting rod 12 is more firm and stable. Furthermore, the structural strength of the entire cross beam 1 is strong and the load-bearing capacity is high. During the high-speed and high-strength cutting process, the cutting stability can be maintained, the cutting surface is flatter, and the cutting efficiency is higher. Moreover, the abutting part 121 of the connecting rod 12 abuts against the inner side surface of the outer side plate 112, the welding position of the abutting part 121 is on the inner side surface of the outer side plate 112, and the stress position is on the inner side surface of the outer side plate 112.

Therefore, the insertion and assembly position and the welding position are not in the same vertical plane, the stress is dispersed, and the loosening and fracture caused by the concentrated stress at the welding joint of the first support beam 11 and the connecting rod 12 are avoided, so that the saw blade cutting assembly cannot cut the stone smoothly on the cross beam 1. Moreover, the insertion and assembly relationship between the connecting rod 12 and the first support beam 11 can limit the relative position relationship between the connecting rod 12 and the first support beam 11, and the assembly accuracy and assembly efficiency are high. The displacement during the welding process is avoided, so that the two first support beams 11 cannot be arranged in parallel, and it can be ensured that the two first support beams 11 are arranged in parallel, and the saw blade cutting assembly can move horizontally and cut the stone smoothly. The insertion part 122 is inserted into the slot 1121, and welding can be carried out from the position of the slot 1121 on the outer side surface of the outer side plate 112, and the welding is more convenient and fast.
