Description

Technical Field

[0001] This utility model relates to the field of mechanical processing technology, and in particular to a clamping mechanism for a stone straight edge chamfering machine. Background Technology

[0002] Straight edge chamfering is the most basic type of chamfering in stone processing. It involves cutting the edge of the stone straight to form a straight chamfer. Straight edge chamfering is suitable for various types of stone and has a wide range of applications, including building corners, step edges, and other decorative scenarios.

[0003] In actual use, the existing stone straight edge beveling machine has been found to have the following shortcomings:

[0004] Existing stone chamfering machines require mechanical positioning of the stone during chamfering, achieved through clamps and guide rails. Each clamp needs to be fixed to one of the four ends of the stone. This means that after processing and adjustment, the clamps must be removed one by one before processing the next set of stones. The next set of stones requires re-mechanical positioning, resulting in long clamping and fixing times when processing stone continuously, which affects the overall processing efficiency.

[0005] Therefore, this application provides a clamping mechanism for a stone straight edge beveling machine to meet the requirements. Utility Model Content

[0006] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology, and to propose a clamping mechanism for a stone straight edge beveling machine.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A clamping mechanism for a stone straight edge beveling machine includes: a base, a track, a first CNC drive machine, a crossbeam, a second CNC drive machine, a transmission motor, a beveling disc, a frame, a placement rack, a slider, a support frame, a baffle, an electric telescopic rod, a vacuum suction cup, a connecting pipe, and a vacuum generator. The top of the base is mounted on the track, and the first CNC drive machine is mounted on the outer side of the track. A crossbeam is mounted on the top of the first CNC drive machine, and the second CNC drive machine is mounted at the upper outer end of the crossbeam. A transmission motor is mounted at the upper end of the second CNC drive machine. A chamfered disc is installed at the lower end of the drive motor. A frame is installed at the upper inner side of the base. A slide rail is provided along the inner edge of the frame. A placement frame is installed at the upper inner side of the frame. A slider is installed on the slide rail of the frame. A support frame is welded to the other end of the slider. A baffle is installed in the middle of the inner side of the support frame. An electric telescopic rod is installed on the side of the baffle. A vacuum suction cup is installed at the output end of the electric telescopic rod. A connecting pipe is installed at the bottom of the vacuum suction cup. A vacuum generator is installed at the lower inner side of the base.

[0009] Preferably, the placement rack is rectangular and there are two sets of placement racks, which are horizontally mounted on the upper end of the slide rail.

[0010] Preferably, the support frame is rectangular and is mounted on the frame via a slider, and the support frame is slidably connected to the frame via the slider and the slide rail.

[0011] Preferably, the support frame is provided in two sets, and the two sets of support frames are horizontally mounted on the upper end of the slide rail.

[0012] Preferably, the support frame is located at the lower end of the placement frame, and the support frame and the placement frame are arranged in a "well" pattern.

[0013] Preferably, two sets of electric telescopic rods are installed on the inner side of the support frame. The two sets of electric telescopic rods are located at the left and right ends of the baffle, respectively, and the output end of the electric telescopic rods extends to the end of the support frame.

[0014] Preferably, the vacuum suction cup extends upward to the upper end of the support frame, and the opening of the vacuum suction cup is oriented upward.

[0015] Preferably, the vacuum suction cup is connected to the vacuum generator's extraction pipe via a connecting pipe.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects:

[0017] In the above solution, a support frame is installed at the lower end of the placement rack. An electric telescopic rod and a vacuum suction cup are installed inside the support frame. The vacuum suction cup is connected to a vacuum generator via a connecting pipe. The output end of the electric telescopic rod can drive the vacuum suction cup to extend and retract, thereby adjusting the position of the vacuum suction cup. The stone is placed on the rack with its edges exposed at the outer end of the rack and its bottom against the vacuum suction cup. After the vacuum suction cup on the support frame contacts the stone, the vacuum generator is activated to draw air, creating negative pressure inside the suction cup, thus firmly holding the stone in place. This allows for quick fixation of the stone, enabling chamfering along the stone's edges and improving the efficiency of stone processing.

[0018] In the above solution, the stone is fixed at the bottom by a vacuum suction cup, which exposes the edge of the stone. There is no need to adjust the position of the clamping mechanism, so the stone can be continuously chamfered, which effectively improves the efficiency of stone processing.

[0019] In the above solution, after processing is completed, the vacuum generator is turned off, so that the air pressure inside the vacuum suction cup changes from negative to zero or slightly positive. The vacuum suction cup then detaches from the bottom of the stone, which can quickly loosen the stone and facilitate chamfering of the next piece of stone, thus improving the efficiency of stone processing.
