Description

Technical Field

[0001] The utility model belongs to the technical field of stone processing machinery, in particular to a bridge type cutting machine. Background Art

[0002] Slate is made of natural stone and inorganic clay through a special process. Its hardness is relatively high, so it is usually necessary to use a large cutting machine to cut it during processing. In the demand of the slate market, the processing of slate requires cutting the four perimeters of the slate to precise angles and accurately chamfering the edges to be spliced. Only in this way can the cut slates meet the requirement of approximately 90° diagonal splicing between each other. In actual production, it is usually processed to between 42 and 44 degrees, so that there is space in the middle for the adhesive to flow in when the two slates are spliced ​​together, making the splicing of the slates more convenient.

[0003] Currently, the China Patent Network discloses a multifunctional rock slab cutting machine [Authorization Announcement No.: CN215359239U], which includes a frame, a worktable, a worktable tilting mechanism, a cutting mechanism, a transverse drive device, and a longitudinal drive device. The cutting mechanism is laterally movable and mounted on a crossbeam. The cutting mechanism includes a base, a rotating shaft rotatably mounted on the base, a cutting head connected to the rotating shaft and located below the base, a drive assembly disposed in the base and connected to and driving the rotating shaft, and a positioning mechanism disposed on the base for limiting the rotation angle of the rotating shaft. The cutting blade has a cutting angle adjustment structure, specifically comprising a tilting assembly disposed on the housing, connected to and driving the motor fixing plate to tilt. The tilting assembly includes a rotating shaft rotatably mounted in the housing, a swing arm connected to one end of the rotating shaft, a tilting cylinder connected to and driving the swing arm to rotate, and a cylinder seat disposed on the housing for mounting the tilting cylinder. The motor fixing plate is connected to the rotating shaft, and the tilting cylinder is hingedly connected to the cylinder seat. During chamfering, the tilting cylinder drives the swing arm to rotate, driving the rotating shaft to rotate, thereby driving the motor fixing plate to tilt, thereby changing the cutting angle of the cutting blade to chamfer the cut edge of the rock slab.

[0004] The above-mentioned multifunctional rock slab cutting machine has the following defects: the cutting angle adjustment of the cutting blade depends entirely on the movement stroke of the piston rod of the flip cylinder. For example, when the cutting angle of the cutting blade needs to be adjusted to 45°, the extension length of the piston rod needs to be precisely controlled. This method has high requirements for the control of the extension stroke of the piston rod, and errors are very likely to occur, resulting in low cutting angle adjustment accuracy. Utility Model Content

[0005] The purpose of the present invention is to solve the above problems in the existing technology and propose a bridge type cutting machine. The technical problem to be solved by the present invention is: how to solve the problem of low cutting angle adjustment accuracy of the existing cutting blade.

[0006] The purpose of this utility model can be achieved through the following technical solutions:

[0007] A bridge-type cutting machine comprises a mounting base and a cutting head rotatably connected to the mounting base via a rotating shaft, the cutting head having a cutting blade, and a cylinder fixed on the mounting base for driving the cutting head to swing up and down. The machine is characterized in that a positioning block is provided on the cutting head, and a limiting block is provided on the mounting base. When the cutting head rotates and drives the cutting blade to rotate to an inclined state, the positioning block abuts against the limiting block.

[0008] In the initial state, the cutting blade is in a vertical state. When the angle of the workpiece needs to be adjusted, the cylinder drives the cutting head to swing downward. The existing workpiece is usually a stone slab, etc. When installed on the countertop, it is usually necessary to cut the stone slab with a chamfer of about 45 degrees. Therefore, the cutting head can be driven by the cylinder to swing, so that the cutting blade is adjusted from a vertical state to an inclined state, and swung until the positioning block 1 abuts against the limit block 1. The cutting head is limited, thereby limiting the rotation of the cutting head, ensuring that the cutting head is positioned after rotating to a fixed angle. In this way, there is no need to control the movement stroke of the piston rod of the cylinder, which improves the convenience and accuracy of the cutting blade angle adjustment, thereby ensuring the cutting accuracy.

[0009] In the above-mentioned bridge-type cutting machine, the positioning block 1 has a protruding positioning portion 1, and the limiting block 1 is provided with a limiting groove 1, and the positioning portion 1 can be embedded in the limiting groove 1.

[0010] When the cutting head rotates to a certain angle, the cutting blade is in an inclined state. At this time, the positioning part 1 is embedded in the limiting groove 1. The limiting groove 1 limits the positioning part 1 to prevent the positioning part 1 from shifting. At the same time, it also positions the cutting head, so that the cutting head has better stability during the stone cutting process and avoids the cutting head from shaking left and right.

[0011] In the above-mentioned bridge-type cutting machine, a strip-shaped hole 1 is opened on the mounting seat, a bolt 1 is passed through the strip-shaped hole 1, and the bolt 1 is fixedly connected to a limiting block 1.

[0012] When bolt 1 is loosened, bolt 1 can move in strip hole 1, thereby driving limit block 1 to move along the length direction of strip hole 1, adjusting the position of limit block 1, and then adjusting the rotation angle of the cutting head, so that the rotation angle of the cutting head can be dynamically adjusted within a certain range to meet the needs of different cutting angles.

[0013] In the above-mentioned bridge-type cutting machine, a second positioning block is provided on the cutting head, and a second limiting block is provided on the mounting seat. When the cutting head is rotated upward by a certain angle so that the cutting blade is in a vertical state, the second positioning block abuts against the second limiting block.

[0014] The cutting head rotates and resets so that the cutting blade returns to a vertical state from an inclined state. After the cutting head rotates back a certain angle, the positioning block 2 abuts against the limit block 2, indicating that the cutting head is reset in place, thereby ensuring that the cutting blade can be accurately reset.

[0015] In the above-mentioned bridge-type cutting machine, the second positioning block has a second protruding positioning portion, and the second limiting groove is provided on the second limiting block, and the second positioning portion can be embedded in the second limiting groove.

[0016] When the cutting head rotates to a certain angle, the cutting blade is in a vertical state. At this time, the positioning part 2 is embedded in the limiting groove 2. The limiting groove 2 limits the positioning part 2 to prevent the positioning part 2 from being offset. At the same time, it also positions the cutting head, so that the cutting head has better stability during the stone cutting process and avoids the cutting head from shaking left and right.

[0017] In the above-mentioned bridge-type cutting machine, a second strip-shaped hole is opened on the mounting seat, a second bolt is passed through the second strip-shaped hole, and the second bolt is fixedly connected to the second limiting block.

[0018] When bolt two is loosened, bolt two can move in strip hole two, thereby driving limit block two to move along the length direction of strip hole two, adjusting the position of limit block two, and then adjusting the rotation angle of the cutting head when it is reset, further increasing the rotation angle adjustment range of the cutting head to meet the needs of different cutting angles.

[0019] In the above-mentioned bridge-type cutting machine, the cutting head includes a mounting bracket, the mounting seat has a mounting cavity, the mounting bracket is located in the mounting cavity, and the left and right sides of the mounting bracket are connected to the mounting seat through the rotating shaft.

[0020] The cutting head is rotatably connected to the mounting base through the mounting bracket. The hinges on the left and right sides facilitate the installation between the mounting bracket and the mounting base, and improve the stability of the mounting bracket's rotation.

[0021] In the above-mentioned bridge-type cutting machine, an articulated seat 1 is provided on the upper surface of the mounting bracket, an articulated seat 2 is provided on the top surface of the mounting cavity, the oil cylinder is arranged in the mounting cavity, the piston rod of the oil cylinder is hinged to the articulated seat 1, and the rear end of the oil cylinder is hinged to the articulated seat 2.

[0022] The oil cylinder is arranged in the installation cavity, making the overall structure more compact, small in size and more space-saving.

[0023] Compared with the prior art, the bridge-type cutting machine of the present invention has the following advantages: when the cutting blade needs to be adjusted in angle, the oil cylinder drives the cutting head to swing downward, so that the cutting blade is adjusted from a vertical state to an inclined state. At this time, positioning block 1 abuts against limit block 1, thereby limiting the rotation of the cutting head, ensuring that the cutting head is positioned after rotating to a fixed angle. In this way, there is no need to control the movement stroke of the piston rod of the oil cylinder, which improves the convenience and accuracy of the cutting blade angle adjustment, thereby ensuring the cutting accuracy.

DETAILED DESCRIPTION

[0031] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0032] like Figure 1 As shown, the bridge-type cutting machine includes a mounting base 1 and a cutting head 3 rotatably connected to the mounting base 1 via a rotating shaft 2 .

[0033] Specifically, if Figure 1-5As shown, the cutting head 3 has a cutting blade 30, and the cutting head 3 includes a mounting bracket 31. The mounting base 1 has a mounting cavity 13. The mounting bracket 31 is located in the mounting cavity 13. The left and right sides of the mounting bracket 31 are connected to the mounting base 1 through the rotating shaft 2. A cylinder 4 is fixed to the mounting base 1 to drive the cutting head 3 to swing up and down. The cylinder 4 is arranged in the mounting cavity 13. The upper surface of the mounting bracket 31 is provided with an articulated seat 14. The top surface of the mounting cavity 13 is provided with an articulated seat 2 15. The cylinder 4 is arranged in the mounting cavity 13. The piston rod of the cylinder 4 is hinged to the articulated seat 14, and the rear end of the cylinder 4 is hinged to the articulated seat 2 15. In this embodiment, there are two cylinders 4, and the two cylinders 4 are respectively arranged near the left and right side walls of the mounting cavity 13.

[0034] like Figure 2 As shown, a positioning block 5 is provided on the cutting head 3, and a limiting block 6 is provided on the mounting seat 1. The positioning block 5 has a raised positioning portion 50, and a limiting groove 60 is provided on the limiting block 6. The positioning portion 50 can be embedded in the limiting groove 60. In this embodiment, the positioning block 5 is provided on the inner wall of the mounting cavity 13, and the left and right side walls of the mounting cavity 13 are both provided with positioning blocks 5. The limiting block 6 is provided on the upper surface of the mounting bracket 31. Similarly, limiting blocks 6 are provided on the left and right sides of the upper surface of the mounting bracket 31. In the initial state, the cutting blade 30 is in a vertical state. When the angle of the cutting blade 30 needs to be adjusted, the cylinder 4 drives the cutting head 3 to swing downward by a certain angle, so that the cutting blade 30 is adjusted from a vertical state to an inclined state. At this time, the positioning part 50 is embedded in the limiting groove 60, thereby limiting the rotation of the cutting head 3, ensuring that the cutting head 3 is positioned after rotating a fixed angle. In this way, there is no need to control the movement stroke of the piston rod of the cylinder 4, which improves the convenience and accuracy of the angle adjustment of the cutting blade 30, thereby ensuring the cutting accuracy.

[0035] like Figure 5 and Figure 6 As shown, the cutting head 3 is provided with a positioning block 2 9, and the mounting base 1 is provided with a limiting block 2 10. When the cutting head 3 is rotated upward by a certain angle so that the cutting blade 30 is in a vertical state, the positioning block 2 9 abuts against the limiting block 2 10. The positioning block 2 9 has a raised positioning portion 2 90, and the limiting block 2 10 is provided with a limiting groove 2 100. The positioning portion 2 90 can be embedded in the limiting groove 2 100. The cutting head 3 is rotated and reset so that the cutting blade 30 returns to a vertical state from an inclined state. After the cutting head 3 is rotated back by a certain angle, the positioning portion 2 90 is embedded in the limiting groove 2 100, indicating that the cutting head 3 is reset in place, thereby ensuring that the cutting blade 30 can be accurately reset.

[0036] like Figure 2 and Figure 3As shown, the mounting base 1 is provided with a strip-shaped hole 7, through which a bolt 8 is passed. Bolt 8 is fixedly connected to the stop block 6. When bolt 8 is loosened, bolt 8 moves within the strip-shaped hole 7, thereby driving the stop block 6 to move along the length of the strip-shaped hole 7. Adjusting the position of the stop block 6, and thus adjusting the rotation angle of the cutting head 3, allows the rotation angle of the cutting head 3 to be dynamically adjusted within a certain range to meet the requirements of different cutting angles.

[0037] like Figure 4 and Figure 5 As shown, the mounting base 1 is provided with a second strip-shaped hole 11, through which a second bolt 12 is passed. The second bolt 12 is fixedly connected to the second limit block 10. When the second bolt 12 is loosened, the second bolt 12 can move within the second strip-shaped hole 11, thereby driving the second limit block 10 to move along the length of the second strip-shaped hole 11. Adjusting the position of the second limit block 10 can adjust the rotation angle of the cutting head 3 when it is reset, further increasing the rotation angle adjustment range of the cutting head 3 to meet the needs of different cutting angles.

[0038] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
