Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Example:

[0024] See also Figure 1-3 The present embodiment provides a positioning device for marble cutting, including a cutting table 1, a cutting mechanism 2 is fixedly installed at the rear end of the top of the cutting table 1, a cutting groove 101 is opened on the cutting table 1 at the cutting mechanism 2, the cutting mechanism 2 includes a cutting machine and a horizontal moving module, which is used to cut the marble on the cutting table 1. This is a prior art and will not be described in detail here. A positioning baffle 3 is fixedly installed on one side of the top of the cutting table 1, a fixing mechanism 4 is installed at the front end of the cutting table 1, and an auxiliary moving component 5 is arranged at the bottom of the cutting table 1.

[0025] Specifically, when cutting marble, the marble to be cut is placed on the top of the cutting table 1, one end of the marble is positioned on the positioning baffle 3, and then the marble is moved to adjust its cutting position, and the friction between the marble and the cutting table 1 is reduced by the auxiliary moving component 5, which facilitates the adjustment of the marble cutting position and improves the convenience of adjustment. After the marble position is adjusted, the marble is positioned and fixed on the cutting table 1 by the fixing mechanism 4 to prevent the marble cutting position from being offset, thereby improving the cutting quality.

[0026] In this embodiment, if Figure 2 As shown, the fixing mechanism 4 includes a fixing frame 401 fixedly connected to the cutting table 1, a material pressing assembly arranged inside the fixing frame 401, and an adjusting assembly for adjusting the height of the material pressing assembly. When positioning and fixing the marble to be cut, the adjusting assembly is used to adjust the height of the material pressing assembly, so that the marble is pressed and fixed by the material pressing assembly, which has the effect of positioning and fixing the marble to be cut.

[0027] In this embodiment, if Figure 2 As shown, the pressing assembly includes a horizontal plate 402 arranged inside a fixed frame 401, a plurality of vertical plates 403 are fixedly connected to the bottom of the horizontal plate 402 along the length direction, the vertical plates 403 are vertically arranged to the horizontal plate 402, and a plurality of pressing blocks 404 are fixedly connected to the bottom of the vertical plate 403 at equal intervals, the pressing blocks 404 are made of rubber, and pressure is applied to multiple points of the marble through the plurality of pressing blocks 404 to improve the positioning and fixing effect of the marble.

[0028] In this embodiment, if Figure 2 As shown, the adjustment assembly includes a threaded sleeve 405 fixedly connected to the fixing frame 401, a threaded rod 406 threadedly connected to the inside of the threaded sleeve 405, the bottom end of the threaded rod 406 is rotatably connected to the horizontal plate 402, and the top of the threaded rod 406 is fixedly connected with a rotating handle 407. The operator drives the threaded rod 406 to rotate in the threaded sleeve 405 by rotating the rotating handle 407, thereby facilitating the adjustment of the overall height of the pressing assembly and facilitating the positioning and fixing of the marble.

[0029] In this embodiment, if Figure 2 As shown, guide rods 408 are symmetrically arranged on both sides of the threaded rod 406, and guide sleeves 409 are fixedly installed on the fixed frame 401 corresponding to the guide rods 408. The bottom end of the guide rod 408 is fixedly connected to the cross plate 402, and the top end of the guide rod 408 passes through the guide sleeve 409 and is slidably connected to the guide sleeve 409. During the height adjustment of the pressing assembly, the pressing assembly slides in the guide sleeve 409 through the guide rods 408, which plays a role of limiting and guiding the height adjustment, thereby improving the stability of the height adjustment of the pressing assembly.

[0030] In this embodiment, if Figure 1 and Figure 3As shown, the auxiliary moving component 5 includes a lifting plate 501, and a plurality of fixed columns 502 are arranged and fixedly installed on the top of the lifting plate 501. The top of the fixed column 502 is rollingly connected with a ball 503. A through hole 102 is opened on the cutting table 1 for the fixed column 502 to pass through. When the cutting position of the marble to be cut is adjusted, the lifting plate 501 is in an ascending state, and the fixed column 502 is passed through the through hole 102, so that the ball 503 protrudes from the upper surface of the cutting table 1. The ball 503 supports and lifts the marble to be cut. When the marble to be cut moves to adjust its position, the rolling friction between the marble to be cut and the ball 503 greatly reduces the friction of the marble movement and improves the convenience of adjusting the position of the marble.

[0031] In this embodiment, if Figure 2 As shown, a linkage member 6 is arranged between the pressing assembly and the lifting plate 501, and the linkage member 6 includes a U-shaped frame 601 fixedly connected to both sides of the horizontal plate 402, and a lifting plate 602 is fixedly connected between the tops of the two U-shaped frames 601, and the lifting plate 602 is located below the lifting plate 501. When the pressing assembly is in a state where the marble is not pressed and fixed, the pressing assembly is in a higher horizontal position. At this time, the pressing assembly drives the U-shaped frame 601 and the lifting plate 602 to move upward synchronously, and lifts the lifting plate 501, so that the ball 503 protrudes from the upper surface of the cutting table 1, which is convenient for moving and adjusting the position of the marble and is not easy to scratch the marble. When the pressing assembly is in a state where the marble is lowered to position and fix the marble, the pressing assembly drives the U-shaped frame 601 and the lifting plate 602 to move downward synchronously. At this time, the lifting plate 501 moves downward synchronously with the lifting plate 602, so that the fixing column 502 and the ball 503 are separated from the through hole 102, thereby placing the marble on the table surface of the cutting table 1, which is helpful for the positioning and fixing operation of the marble.

[0032] In this embodiment, if Figure 3 As shown, sliding holes 5011 are provided at the four corners of the lifting plate 501, and a limiting slide bar 504 is slidably connected in the sliding hole 5011. The top of the limiting slide bar 504 is fixedly connected to the cutting table 1, and the bottom end of the limiting slide bar 504 is threadedly connected to the limiting nut 505. When the lifting plate 501 is lifted and lowered, the lifting plate 501 is slidably connected to the limiting slide bar 504, thereby improving the stability of the movement of the lifting plate 501 and ensuring the accuracy of the alignment of the fixed column 502 and the through hole 102.

[0033] In this embodiment, if Figure 1 As shown, a scale mark line is provided on one side of the positioning baffle 3 close to the fixing mechanism 4 to facilitate the precise adjustment of the marble cutting position.

[0034] Working principle: When in use, place the marble to be cut on the top of the cutting table 1, and position one end of the marble against the positioning baffle 3. At this time, the material pressing assembly is in a state of not pressing and fixing the marble, and the material pressing assembly is in a relatively high horizontal position. The material pressing assembly drives the U-shaped frame 601 and the lifting plate 602 to move upward synchronously, and lifts the lifting plate 501, so that the ball 503 protrudes from the upper surface of the cutting table 1. The ball 503 supports and lifts the marble to be cut, and then adjusts the cutting position of the marble. After the adjustment of the marble position is completed, The operator drives the threaded rod 406 to rotate in the threaded sleeve 405 by turning the rotating handle 407, and moves the pressing assembly downward. The pressing assembly drives the U-shaped frame 601 and the lifting plate 602 to move downward synchronously, and the lifting plate 501 moves downward synchronously with the lifting plate 602, so that the fixing column 502 and the ball 503 are disengaged from the through hole 102, thereby placing the marble on the table surface of the cutting table 1, and applying pressure to the marble at multiple points through the pressing assembly, thereby improving the positioning and fixing effect of the marble, preventing the marble cutting position from shifting, and improving the cutting quality.

[0035] All technical features in this embodiment can be freely combined according to actual needs.

[0036] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
