DETAILED DESCRIPTION
[0022] like Figure 1 and 2 As shown, a special-shaped stone cutting clamp includes a fixed clamping plate mechanism and at least one group of movable clamping plate mechanisms. In this embodiment, two groups of movable clamping plate mechanisms are arranged, and the fixed clamping plate mechanism and the movable clamping plate mechanism are arranged opposite to each other. The fixed clamping plate mechanism is fixed on the cutting machine base, and the movable clamping plate mechanism can move relative to the fixed clamping plate mechanism.
[0023] The fixed clamping plate mechanism includes an end fixed base plate 1 and a fixed support mechanism 2 arranged at the lower end of the end fixed base plate 1. The end fixed base plate 1 is arranged vertically, and the fixed support mechanism 2 is arranged horizontally. The end fixed base plate 1 and the fixed support mechanism 2 form an "L"-shaped structure. In this embodiment, a connecting seat 101 is provided at the lower end of the end fixed base plate 1. A threaded hole 102 is provided on the connecting seat 101. The connecting seat 101 is used to connect with the cutting machine base to achieve a detachable connection of the fixed clamping plate mechanism. The movable clamping plate mechanism includes an end movable base plate 13 and a movable support mechanism 3 arranged at the lower end of the end movable base plate 13. The end movable base plate 13 and the movable support mechanism 3 are vertically connected to form an "L"-shaped structure.
[0024] The fixed support mechanism 2 includes a plurality of limit rods 201, and the movable support mechanism 3 is provided with a plurality of limit slots 301 cooperating with the limit rods 201. The limit slots 301 are open slots. By inserting the limit rods 201 into the limit slots 301, the nesting cooperation of the fixed support mechanism 2 and the movable support mechanism 3 is achieved. In this embodiment, preferably, as Figure 3~4 As shown, protrusions 202 are provided on both sides of the limiting rod 201, and the inner wall of the limiting groove 301 is provided with grooves 302 that cooperate with the protrusions 202. Through the cooperation between the protrusions and the grooves 302, the movable supporting mechanism 3 can be prevented from moving up and down and limited up and down.
[0025] The end fixed base plate 1 and the end movable base plate 13 are connected by an adjusting screw 4 and an adjusting nut 5. By rotating the adjusting nut 5, the distance between the end fixed base plate 1 and the end movable base plate 13 is adjusted, so that the fixed clamping plate mechanism and the movable clamping plate mechanism move relative to each other.
[0026] like Figure 1~2 and Figure 5 As shown, the front clamping plate 6 is provided on the opposite sides of the end fixed base plate 1 and the end movable base plate 13. The front clamping plate 6 is the main component for clamping the stone. The front clamping plate 6 is connected to the corresponding end fixed base plate 1 or the end movable base plate 13 through a connecting mechanism 7. In this embodiment, the connecting mechanism 7 includes a connecting column 701. One end of the connecting column 701 is connected to the front clamping plate 6 by screws, and the other end is connected to the end fixed base plate 1 or the end movable base plate 13 by screws. By replacing the connecting column 701 of different lengths, the distance between the front clamping plate 6 and the end fixed base plate 1 or the end movable base plate 13 can be conveniently adjusted. The end fixed base plate 1, the end movable base plate 13, and the front clamping plate 6 are all provided with a plurality of through holes for the clamping rod 8 to pass through. The fixed clamping plate mechanism and the movable clamping plate mechanism both include a plurality of groups of clamping rods 8, which are arranged in an array. The clamping rod 8 is provided with a limiting mechanism 9 and a clamping spring 10. The clamping spring 10 is arranged between the limiting mechanism 9 and the end fixed base plate 1 or between the limiting mechanism 9 and the end movable base plate 13. The limiting mechanism 9 may be an annular protrusion or a spring collar. The limiting mechanism 9 serves to tighten the clamping spring 10. In the present embodiment, the limiting mechanism 9 uses a spring collar to facilitate position adjustment.
[0027] During specific use, the relative distance between the fixed clamping plate mechanism and the movable clamping plate mechanism is adjusted by rotating the adjusting nut 5, thereby driving the front end clamping plates 6 of the fixed clamping plate mechanism and the movable clamping plate mechanism to move toward each other. When the clamping rod 8 contacts the stone and moves outward, the clamping spring 10 is compressed to form a clamping force on the stone. The adjusting nut 5 is continued to be rotated until multiple groups of clamping rods 8 are in contact with the stone. Since multiple groups of clamping rods 8 are provided, the stone can be fixed at multiple points, thereby improving the clamping effect and meeting the clamping requirements of stones of different sizes and shapes.
[0028] Preferably, Figure 1 and 6 As shown, the fixed clamping plate mechanism and the movable clamping plate mechanism both include a movable clamping plate 11, which is arranged between the front end clamping plate 6 and the end fixed base plate 1 or between the front end clamping plate 6 and the end movable base plate 13. A clamping hole 1101 is arranged on the movable clamping plate 11 corresponding to the clamping rod 8. The clamping hole 1101 is a strip hole, which is arranged horizontally and has a width greater than the diameter of the clamping rod 1101. A clamping tooth 1102 is arranged at the bottom of the clamping hole 1101, and an insertion rod 1103 is arranged at the bottom of the movable clamping plate 11. Plug holes corresponding to the insertion rod 1103 are arranged on the fixed support mechanism 2 and the movable support mechanism 3, and a spring is arranged on the insertion rod 1103. A limiting tooth 801 corresponding to the clamping tooth 1102 is arranged on the outer side of the clamping rod 8. The spring pushes the movable clamping plate 11 upward, and the limiting tooth 801 cooperates with the clamping tooth 1102 to limit the movement of the clamping rod 8.
[0029] During use, when clamping the stone, the movable clamping plate 11 is pressed downward, the clamping tooth 1102 disengages from the limiting tooth 801, and the movement limit of the clamping rod 8 is released. The adjusting nut 5 is rotated to adjust the relative distance between the fixed clamping plate mechanism and the movable clamping plate mechanism. When the front end clamping plate 6 and the clamping rod 8 complete the clamping of the stone, the pressure on the movable clamping plate 11 is released. Under the action of the spring, the movable clamping plate 11 moves upward, and the limiting tooth 801 cooperates with the clamping tooth 1102 to limit the movement of the clamping rod 8, thereby locking the clamping rod 8 to prevent the clamping rod 8 from moving randomly due to cutting vibration and to prevent the stone from loosening during cutting.
[0030] Preferably, a rotating clip 14 is provided at the upper end of the end fixed base plate 1 and the end movable base plate 13. The rotating clip 14 is rotatably mounted on the top of the end fixed base plate 1 or the end movable base plate 13 through a rotating shaft 15. When the rotating clip 14 rotates to the upper side of the movable clamping plate 11, the movable clamping plate 11 is limited up and down. After the movable clamping plate 11 is pressed downward, the rotating clip 14 is rotated to press it on the upper side of the movable clamping plate 11, so that the movable clamping plate 11 does not need to be pressed all the time.
[0031] Furthermore, a spring limiting plate 12 is provided between the movable clamping plate 11 and the front end clamping plate 6. The spring limiting plate 12 is arranged close to the movable clamping plate 11. The spring limiting plate 12 is provided with a through hole for the clamping rod 8 to pass through. The clamping spring 10 is arranged between the limiting mechanism 9 and the spring limiting plate 12. By providing the spring limiting plate 12, the clamping spring 10 can be reliably supported to prevent the clamping spring 10 from moving up and down with the movable clamping plate 11 and affecting the tightening force.
[0032] The spring limiting plate 12 is provided with limiting slots 1201 cooperating with the connecting column 701 . The limiting slots 1201 are arranged at four corners and cooperate with the connecting column 701 . The spring limiting plate 12 is limited by installing the connecting column 701 .
[0033] The clamp improves the fixing effect when cutting irregular shaped stones, reduces the looseness that may occur during cutting, improves the accuracy of cutting sampling, and reduces the waste caused by looseness during cutting.
