Description

Technical Field

[0001] The present invention relates to the technical field of stone corner stone cutting, and mainly relates to a corner stone cutting device which has both large and small disc saws and can realize bidirectional rotation, that is, a bidirectional rotating dual-independent drive blade saw cutting assembly for stone cutting. Background Art

[0002] Cutting machines are well-established processing machines, widely used for cutting materials. The most common are stone cutters, which are typically used to cut large blocks of rough stone into slabs of the desired thickness. In actual stone construction applications, corner profiles are often required, such as stairs, door and window moldings, decorative wall corners, skirtings, bar counters, sinks, and large curbstones. Because existing stone cutters cannot directly process corner profiles, they are labor-intensive, time-consuming, and wasteful. Therefore, when required, workers typically glue two slabs together at the corner. However, these angular stones suffer from issues such as aging and shedding of the glue, which affects their aesthetics, is difficult to construct, and suffers from poor mechanical strength.

[0003] At present, when cutting stones, especially when bridge cutting equipment uses disc cutting, it is often necessary to cut the same seam of the stone with large and small cutters. When this operation is performed, it is often necessary to stop the machine to replace the large and small cutters. The process is time-consuming, reduces work efficiency, and is very inconvenient to use. Moreover, when it is necessary to cut corner stones with an inclination angle greater than or less than a right angle, it is also necessary to adjust the angle of the stone, which is tedious, laborious and time-consuming. Moreover, the current cutting method causes the cutting seam of the stone to be thicker, which increases the loss of stone and causes a certain amount of waste. Summary of the Invention

[0004] In order to solve the shortcomings and defects of the above-mentioned existing technologies, the inventors have designed a cutting device for integrated cutting and shaping of corner stones with long surfaces in one go after research and development. The device can switch between large and small disk saws without replacing the disk saw, and can adjust the up and down tilt of the disk saw and the height rotation and lifting function of the large and small disk saws according to needs. This two-way cutting assembly is suitable for installation and use on various types of bridge cutting equipment to achieve high efficiency of the cutting process. It has a wide range of applications and is convenient and easy to operate and adjust.

[0005] Specifically, the present invention is implemented as follows: a cutting assembly of a bidirectional rotating dual-independently driven blade saw for stone cutting, which is pressed on the bridge cutting guide column through a bridge cutting guide column connecting plate, and the adjustment spindle is installed below the bridge cutting guide column connecting plate in an installation manner with adjustable up and down tilt angles, and the front and rear ends of the motor connecting plate are both sleeved on the end shafts at both ends of the adjustment spindle through a rotating seat, and can be tilted with the adjustment spindle as the rotating axis, two cutting motors are symmetrically installed on both sides of the adjustment spindle above or below the motor connecting plate, and the cutting motors are directly connected to two large and small disk saws respectively, both disks are located in the cutting surface direction and the rotation direction is perpendicular to the axial direction of the adjustment spindle, the tail end of the motor connecting plate is fixedly connected to the non-rotating part of the rotating power device, and the rotating shaft of the rotating power device is fixedly connected to the end shaft of the adjustment spindle.

[0006] Furthermore, the rotary power device includes a rotary motor, which is connected and installed with a reducer, and the reducer is connected to a rotary seat at the rear end of the motor connecting plate through a connecting flange.

[0007] Furthermore, a pair of rotating adjustment seats are extended downward from the front end of the bottom of the bridge cutting guide column connecting plate, and an adjustment positioning hole is provided at the rear end. A section of adjustment shaft protruding outward is provided on both side surfaces of the front end of the adjustment spindle, and the adjustment shafts are respectively installed in the rotating adjustment seats. An upward extending arc-shaped adjustment fixing seat is installed directly above the rear end of the adjustment spindle, and the arc-shaped adjustment fixing seat is installed on the adjustment positioning hole in an adjustable tightness manner.

[0008] Furthermore, the motor connecting plate is a plate-like body with a wide front end and a narrow rear end. Two openings are dug into the front end portion of the plate in symmetrical areas on both sides of the central axis. The motor connecting plate is respectively installed with a rotating seat at the front and rear ends along the center line. The front end of the motor connecting plate is installed with a saw blade cover that covers the upper half of the two disk saws at the same time.

[0009] Furthermore, when the motor connecting plate is horizontal, the centers of the two circles are located on the same horizontal line, and the distances between the two centers and the rotation axis of the motor connecting plate are equal.

[0010] Furthermore, the rotary power device is relatively fixedly connected to the motor connecting plate. When the rotary power device rotates, the two rotate synchronously with respect to the adjustment main shaft around its axis in a forward direction or reverse direction.

[0011] Furthermore, the adjustment spindle is provided with motor connecting plate limit seats on both sides of one end close to the cutting motor, and the motor connecting plate limit seats are provided with a stabilizing limit screw that can be adjusted in height longitudinally. The stabilizing limit screw contacts the surface of the motor connecting plate to achieve a limiting and stabilizing effect on the motor connecting plate.

[0012] The working principle and beneficial effects of the present invention are introduced as follows: This bidirectional rotary cutting assembly is used to be installed on a bridge cutting machine for use, and its purpose is to perform horizontal cutting of the longitudinal surface of the stone. It is characterized by having two independently driven large and small disk saws on the same cutting line. The large and small disk saws are directly connected and installed on the cutting motor, and the cutting motor is fixedly installed on the motor connecting plate. The front and rear ends of the motor connecting plate are passed through the rotating seat sleeve to realize movable installation on the adjustment spindle, and the adjustment spindle is installed on the bridge cutting guide column through the bridge cutting guide column connecting plate. The rear end of the motor connecting plate is connected to the non-rotating part of the rotary power device, and the rotating shaft of the rotary power device is fixedly connected to the end shaft of the adjustment spindle and cannot rotate. Therefore, when the rotating motor of the rotary power device is started, because the rotating shaft is fixed , it can only drive the entire non-rotating parts to rotate around the rotating shaft, thereby driving the motor connecting plate to rotate synchronously to adjust the height and tilt angles of the two disc saws. The rotation direction can be controlled by the forward and reverse rotation of the rotating motor, that is, the height change between the large and small disc saws relative to the stone can be adjusted. Therefore, this cutting assembly has a variety of cutting modes. When the large and small disc saws are relatively horizontal, the effect of the large and small disc saws cutting the same seam at the same time can be achieved simultaneously. The small disc saw opens the seam first, and the large disc saw performs a deep cut on the basis of the shallow seam. It can cut a certain depth of cut seam in one cutting stroke. When a deeper cutting seam is required, the tilt angle is adjusted to make the large disc saw tilt downward toward the stone, so as to cut a deeper cut seam. Therefore, this equipment can meet the cutting needs of integrated corner stones of various thicknesses. The spindle can be adjusted by adjusting the relative position of the arc-shaped adjustment mount on the rotary adjustment mount, thereby adjusting the horizontal inclination of the entire cutting assembly. This adjustment adjusts the angle between the disc saw and the vertical line, forming an inclined cutting surface. This can be used to cut special-shaped corner stones with acute or obtuse angles between the corner surfaces. Another important aspect is that the structure of the large and small discs of the present invention can narrow the blade gap, reducing stone loss. When used with a transverse cutting band saw, the device can naturally narrow the blade gap. When used with a transverse cutting band saw, it can cut integrated corner stones with unequal thicknesses and variable angles. The cutting head assembly of the present invention features a narrow blade gap, reduced stone loss, and adjustable angles, allowing for cutting of unequal thicknesses according to market demand. This invention further significantly reduces the loss of precious stone. The present invention further improves the cutting efficiency of integrated corner stones, reduces stone waste, and meets the needs of various cutting styles and sizes.

DETAILED DESCRIPTION

[0030] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0031] Example 1: A cutting assembly of a bidirectional rotating dual-independently driven blade saw for stone cutting, which is installed on the bridge cutting guide column 1 through the bridge cutting guide column connecting plate 2, and the adjusting spindle 3 is installed below the bridge cutting guide column connecting plate 2 in an installation manner with adjustable up and down tilt angles, and the front and rear ends of the motor connecting plate 4 are both inserted into the end shafts at both ends of the adjusting spindle 3 through the rotating seat 4-1, and can be tilted on both sides with the adjusting spindle 3 as the rotating axis, and two cutting motors 4-2 are symmetrically installed on both sides of the adjusting spindle 3 above or below the motor connecting plate 4, and the cutting motors 4-2 are directly connected to two large and small disk saws 4-3 respectively, and the two disk saws 4-3 are both located in the cutting surface direction and the rotation direction is perpendicular to the axial direction of the adjusting spindle 3, the tail end of the motor connecting plate 4 is fixedly connected to the non-rotating part of the rotating power device, and the rotating shaft 5-1 of the rotating power device is fixedly connected to the end shaft of the adjusting spindle 3.

[0032] During actual use, the position of the adjustment hole is adjusted so that the adjustment spindle remains at the desired angle. In this embodiment, the horizontal angle is maintained as an example, and the adjustment hole is locked and fixed. The motor connecting plate 4 is used to mount two cutting motors. At the same time, the rotary power device includes a rotating motor 5, which is connected and mounted with a reducer 5-2. The reducer 5-2 is connected to the rotating seat 4-1 at the rear end of the motor connecting plate 4 via a connecting flange 5-3, thereby driving the motor connecting plate to rotate synchronously to adjust the height and tilt angle of the two disk saws. The rotation direction can be controlled by rotating the rotating motor forward and reverse, that is, the height difference between the large and small disk saws relative to the stone can be adjusted.

[0033] The bridge-cutting guide post connecting plate 2 has a pair of downwardly extending rotational adjustment seats 3-1 at its front end, and an adjustment positioning hole 3-2 at its rear end. The front end of the adjustment spindle 3 is provided with an outwardly protruding adjustment shaft 3-3 on each side, each mounted within the rotational adjustment seats 3-1. Just above the rear end of the adjustment spindle 3 is an upwardly extending curved adjustment fixing seat 3-4, which is adjustable in tension within the adjustment positioning hole 3-2. The motor connecting plate 4 is a plate-like body with a wider front end and a narrower rear end. Two openings 4-4 are symmetrically cut into the front end of the plate, located on either side of the central axis. Rotating seats 4-1 are mounted at the front and rear ends of the motor connecting plate 4 along its centerline. A saw cover 4-5 is mounted at the front end of the motor connecting plate 4, covering the upper halves of both saw discs 4-3. The openings 4-4 are designed to prevent the adjustment shaft 3-3 from contacting the motor connecting plate 4 during rotation, thereby restricting its rotation. The rotating base 4-1 is used to connect the rotation system and the motor connecting plate 4, so that the two are linked to each other for rotation. This structure realizes the installation of a disc saw structure with adjustable axial rotation angle on the bridge cutting guide column 1. Without affecting the cutting performance and cutting effect of the disc saw, the axial angle can be adjusted under the condition of movable adjustment. The tilt angle of the large and small disc saws can be controlled. It can achieve a deeper cutting depth and cooperate with the process of cutting in sequence between the large and small disc saws to effectively avoid stone loss in the stone cutting gap, thereby improving the cutting process and reducing stone loss.

[0034] In terms of specific structural details, preferably, when the motor connecting plate 4 is horizontal, the centers of the two circles are located on the same horizontal line and are equidistant from the rotation axis of the motor connecting plate 4. The rotary power device and the motor connecting plate 4 are fixedly connected relative to each other. When the rotary power device rotates, the two rotate synchronously with respect to the adjustment spindle 3 about its axis in the forward or reverse direction.

[0035] Preferably, the adjustment spindle 3 is further provided with a motor connecting plate limit seat 3-5 on both sides of one end close to the cutting motor 4-2. The motor connecting plate limit seat 3-5 is provided with a stabilizing limit screw 3-6 that can be adjusted in height longitudinally. The stabilizing limit screw 3-6 contacts the surface of the motor connecting plate 4 to achieve a limiting and stabilizing effect on the motor connecting plate 4. Since the disk saw will produce vibration during the cutting process and transmit it to the motor connecting plate 4, in order to ensure the cutting quality, the stabilizing limit screw 3-6 installed on the motor connecting plate limit seat 3-5 is manually screwed so that its bottom end contacts the motor connecting plate 4. This is done at both ends, so that the vibration amplitude of the motor connecting plate 4 during the cutting process is limited, thereby effectively maintaining the stability of the motor connecting plate 4, that is, ensuring the stability of the disk saw, improving the smoothness of the cutting process, reducing the loss of stone, and improving the cutting quality.

[0036] It should be understood that the above-described specific embodiments of the present invention are merely illustrative or illustrative of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included within the scope of protection of the present invention. In addition, the appended claims are intended to cover all variations and modifications that fall within the scope and metes and bounds of the appended claims, or equivalents thereof.
