Arc-shaped cutting machine for paving marble slabs on roads

Abstract

The invention discloses an arc-shaped cutting machine for paving marble slabs on roads. The arc-shaped cutting machine comprises a base, a workbench, a power transmission mechanism, a stand column, acutting mechanism and a rotary supporting frame. The stand column is fixed to one end of the base, and the workbench is fixed at the other end of the base; one end of the rotary supporting frame is sleeved with the stand column through a shaft sleeve, the power transmission mechanism is fixed to the other end of the rotary supporting frame, the cutting mechanism is fixed to the bottom of the powertransmission mechanism, the power transmission mechanism comprises a power box and a transmission box, and a motor is mounted in the power box; a cam, a connecting rod, a guide sleeve and a U-shapedsleeve are arranged in the transmission box; the cutting mechanism comprises a knife rest, a cutter and a locking ring; the threaded end of the knife rest is connected into a center threaded hole at the bottom of the U-shaped sleeve through threads, and a cutter clamping groove is formed at the other end of the knife rest; the cutter is arranged in the cutter clamping groove; and the locking ringis sleeved with the cutter clamping groove and fixedly connected to one end of the knife rest. The arc-shaped cutting machine can stably conduct arc cutting on stones, meanwhile, the stones with different thicknesses can be cut, time and labor are saved, and the using requirement is met.

Description

technical field [0001] The invention belongs to the technical field of stone processing for road paving, in particular to an arc cutting machine for road paving marble slabs. Background technique [0002] In urban modernization, urban traffic occupies an important position as infrastructure construction, and corresponding auxiliary roads will be set up on both sides of the main driveway for pedestrians; in terms of road paving, marble, pavement bricks, permeable bricks, etc. are often used, especially marble slabs The thickness is 3-5cm, the texture is hard, and cutting is time-consuming and laborious; and sometimes it is necessary to surround the roots of green trees or sewer wellheads for enveloping pavement, and arc cutting and transformation of stone materials are required. The following questions: [0003] 1) The existing cutting methods are mostly aimed at linear cutting, and it is difficult to perform arc cutting according to the demand; [0004] 2) Most of the exis...

AI Technical Summary

Problems solved by technology

[0002] In the construction of urban modernization, urban traffic occupies an important position as an infrastructure construction, and corresponding auxiliary roads will be set up on both sides of the main driveway for pedestrians; in road paving, marble, pavement bricks, permeable bricks, etc. are often used, especially marble slabs The thickness is 3-5cm, the texture is hard, and cutting is time-consuming and laborious; and sometimes it is necessary to surround the roots of green trees or sewer wellheads for enveloping pavement, and arc cutting and transformation of stone materials are required. The following questions:

[0003] 1) The existing cutting methods are mostly aimed at linear cutting, and it is difficult to perform arc cutting according to the demand;

[0004] 2) Most of the existing cutting methods use hand-held electric cutting machines for stone cutting, especially the commonly used marble slabs. Due to the influence of the diameter of the cutting piece, the arc-shaped route cutting cannot be achieved during cutting; often it takes multiple times The cut surface similar to the required arc cut can be achieved by grinding after straight cutting, and the irregular cutting will easily make the gap larger and unsightly; at the same time, the marble slab cannot be fixed, which is prone to safety accidents

[0005] 3) Existing curve saw cutting cannot achieve arc cutting of marble over 3cm
