Description

Technical Field

[0001] This utility model relates to the field of manually operated single-rail machines, and in particular to a single-rail cutting machine used in the construction industry for marking cutting lines on ceramic parts and dividing ceramic parts along the cutting lines. Background Technology

[0002] Regarding the guide device for the blade holder head, there are basically two types of manual ceramic cutting machines currently known. One type is a cutting machine with two parallel guide rails, in which the blade holder head moves between the two guide rails; the other type is a single-rail cutting machine with a single guide rail, in which the blade holder head moves longitudinally on the single guide rail. The latter type of cutting machine is more closely related to this utility model.

[0003] In the second type, in known manual ceramic cutting machines, the only guide rail for moving the blade holder head is set on one side of the longitudinal plane in the middle of the cutting blade.

[0004] The same applicant for this utility model disclosed the background technology of this type of cutting machine in patent document WO2024110674, which is the closest prior art to this application.

[0005] The manual ceramic cutting machine described in the background section includes: a worktable for supporting the ceramic part to be cut, and a tool holder head that can move along a single longitudinal guide rail. The guide rail is located on one side of the tool holder head, and its two ends are fixed sequentially on supports at opposite ends of the worktable and are offset laterally relative to a vertical plane that coincides with the longitudinal path of the cutting tool.

[0006] The tool holder head is equipped with: a drive handle, a cutting tool for marking cutting lines on the ceramic part, and a spacer for dividing the ceramic part along the pre-marked cutting lines.

[0007] The aforementioned tool holder head is mounted on a component that can move along the aforementioned longitudinal guide rail. A horizontal axis allows the tool holder head to rotate so that the cutting tool and the spacer can move closer to or further away from the ceramic part to be cut, and provides the tool holder head with a lateral distance relative to the longitudinal guide rail.

[0008] In the aforementioned document, the spacer for dividing the ceramic parts along the cutting line is mounted on a horizontal axis and can be moved between a working position and a non-working position by a relatively complex mechanism consisting of a connecting rod and a drive rod mounted on the handle of the cutting machine.

[0009] Traditionally, in ceramic cutting machines of the above type, the cutting tool includes a rotatable cutting wheel mounted on a handle, the outer side of which has a groove or longitudinal plane for mounting a non-rotating housing within the housing of the blade holder head; the cutting tool is fixed in this position by fastening screws that act laterally on the handle supporting the cutting wheel.

[0010] The handle of the cutting tool has a centrally located longitudinal groove at one end, in which the cutting wheel is installed. Therefore, when marking the cutting line on the ceramic part, the handle itself makes the cutting wheel difficult to see, thereby increasing the risk of mismarking.

[0011] The same applicant of this utility model disclosed a cutting tool of this type in patent document EP1306178. Its disadvantage is that a certain gap is required to install it into the housing of the blade holder head. Moreover, due to insufficient tightening or loosening of the fastening screws, the stability of the cutting tool relative to the blade holder head may be affected, which is detrimental to the stability of the cutting wheel and the accuracy of marking the cutting line on the ceramic part.

[0012] Therefore, in order to overcome the above-mentioned defects, it is necessary to develop a single-rail ceramic cutting machine of the above type, which can simplify the cutting machine and improve the accuracy of marking the cutting lines. Utility Model Content

[0013] The single-rail cutting machine of this application is a type that includes a longitudinal guide rail for moving the blade holder head in the longitudinal direction, the cutting wheel has high visibility, the blade holder head slides through a ball bearing, and the longitudinal guide rail is made of aluminum extrusion process, which has the advantages of good vertical and horizontal rigidity.

[0014] Specifically, the single-rail cutting machine for ceramic parts of this utility model includes: a support platform for supporting the ceramic part to be cut, a single longitudinal guide rail mounted on the support platform and laterally offset to one side of the support platform, and a tool holder head mounted on a movable member located on one side of the longitudinal guide rail via a horizontal rotation shaft. The movable member is provided with a first bearing and a second bearing for moving along the longitudinal guide rail, such that the longitudinal guide rail is laterally offset to an asymmetrical position relative to the tool holder head. The tool holder head includes: a drive handle, a cutting wheel for marking a cutting line parallel to the longitudinal guide rail on the ceramic part, a spacer mounted on the tool holder head via a rotation shaft for dividing the ceramic part along the cutting line, and a holding device for holding the spacer in a non-working position.

[0015] The technical features of this single-rail cutting machine can perfectly solve the above-mentioned shortcomings, simplify the cutting machine, optimize the separation device, and provide higher stability and accuracy when marking cutting lines on the ceramic parts through the cutting wheel.

[0016] According to the present invention, the cutting wheel is directly mounted on the blade holder head body via a rotating shaft. Therefore, the cutting wheel does not have a rod or handle for mounting to the blade holder head via fastening elements.

[0017] In this invention, the bottom of the blade holder head is provided with an extension integrally formed with the blade holder head, and the end of the extension is used to directly mount the cutting wheel through the rotating shaft.

[0018] The tool holder head defines an extension for mounting the cutting wheel, avoiding the installation and attachment problems of existing cutting tools, which have handles that support the cutting wheel and are mounted to the tool holder head by screws or fastening elements. It also avoids gaps and errors that occur when these cutting tools mark the cutting line.

[0019] The cutting wheel is mounted on one side of the extension of the cutter head, specifically on the side away from the longitudinal guide rail. Therefore, the entire cutting wheel can be seen from this side of the cutting machine, which makes it easier and more accurate to position the cutting wheel when marking cutting lines on the ceramic part.

[0020] Therefore, the proposed solution can mark the cutting lines on the ceramic part more accurately and with higher quality.

[0021] The spacer of the ceramic part is mounted on the tool holder head via a horizontal rotating shaft and can rotate between two working positions. One working position is in which the spacer is arranged vertically and approximately perpendicular to the ceramic part to be divided. The other working position is in which the spacer is in contact with the lower surface of the tool holder head and does not touch the non-working position of the ceramic part when the cutting wheel marks the dividing line.

[0022] The rotation axis of the spacer is mounted on the horizontal rotation axis of the tool holder head near the tool holder head and toward the drive handle. In this way, when the ceramic part is being cut, the drive handle and the tool holder head assembly form a double lever, thereby increasing the force applied to the drive handle and directly transmitting the force to the spacer.

[0023] According to the present application, the cutting machine includes a magnetic device for holding the spacer in the non-working position, including a magnet disposed on the spacer, wherein when the spacer is in the non-working position, the magnet applies a magnetic force to a screw mounted on the lower surface of the blade holder head.

[0024] This solution is simple and easy to implement, and simplifies the spacer assembly, avoiding the need for linkages or other additional components to position the spacer in the working and non-working positions.

[0025] When the magnetic force of the magnet holds the spacer in the non-working position, it can be set to the working position simply by manually rotating the spacer. Attached Figure Description

[0026] To supplement the description herein and to aid in a better understanding of the features of this invention, a set of drawings are provided, illustrating the following by way of example rather than limitation:

[0028] Figure 2 for Figure 1 A magnified view of a portion of the image;

[0029] Figure 3 and Figure 4 The figure above shows a partial cross-sectional view of a single-rail cutting machine, in which the spacers of the ceramic parts are in the non-working position and the working position, respectively.

[0030] Figure 5 for Figure 3 The image shows a side sectional view of a single-rail cutting machine. Detailed Implementation

[0031] The single-rail cutting machine shown in the attached figure includes: a support table (1) for supporting the ceramic part to be cut, a cutter head (2) with a drive handle (21), a cutting wheel (3) for marking cutting lines on the ceramic part, a spacer (4) for dividing the ceramic part along the cutting lines, and a single longitudinal guide rail (5) that is laterally offset relative to a vertical plane, the vertical plane being coincident with the longitudinal path of the cutting wheel (3) and located in the middle longitudinal region of the worktable (1).

[0032] The blade holder head (2) is mounted on a movable member (6) via a horizontal rotating shaft (22). The movable member (6) is provided with a first bearing (61) and a second bearing (62) that move along the longitudinal slide rail of the longitudinal guide rail (5), so that the movable member (6) can only move along the longitudinal guide rail (5). The horizontal rotating shaft (22) allows the blade holder head (2) to rotate, thereby moving the cutting wheel (3) and the spacer (4) closer to or further away from the ceramic part to be cut.

[0033] like Figures 2 to 4As shown, the tool holder head (2) includes an extension (24) integrally formed at the bottom with the tool holder head (2), and the cutting wheel (3) is directly mounted on the extension (24) via a rotating shaft (31).

[0034] The spacer (4) is mounted to the tool holder head (2) via a rotating shaft (41), the rotating shaft (41) allowing it to be in a certain position. Figure 3 The non-working positions shown are Figure 4 The work location is shown.

[0035] The rotating shaft (41) is installed in a region of the tool holder head (2), close to the horizontal rotating shaft (22) of the tool head (2) and against the drive handle (21), such that when the ceramic part is being cut, the handle (21) and the tool holder head (2) assembly form a double lever, which increases the force applied to the handle (21) and transmits the force directly to the spacer (4).

[0036] The holding device that holds the spacer (4) in the non-working position is magnetic and includes a magnet (42) disposed on the spacer (4) that applies a magnetic force to a screw (23) mounted on the lower surface of the tool holder head (4) when the spacer (4) is in the non-working position.

[0037] The magnetic force of the magnet (42) on the screw (23) enables the spacer (4) to remain in place. Figure 3 The non-working position shown indicates that the spacer (4) should be set to... Figure 4 When in the vertical working position shown, simply rotate the spacer (4) manually until the magnetic force of the magnet (42) is overcome.

[0038] exist Figure 5 In the illustrated embodiment, the cutting wheel (3) is preferably mounted on one side of the extension (24) of the blade holder head (2), especially on the side away from the longitudinal guide rail (5), so that the cutting wheel (3) can be fully seen from the aforementioned side of the cutting machine, and it helps to more accurately position the cutting wheel (3) on the ceramic part in the area where the cutting line needs to be marked.

[0039] In the Figure 5 In the movable part (6), the first bearing (61) is disposed in a vertical plane and does not move vertically relative to the slide rail (51) of the longitudinal guide rail (5). The first bearing (61) bears a vertical load when marking the cutting line on the ceramic part and subsequently dividing it under the action of the spacer (4).

[0040] The second bearing (62) of the movable component (6) is disposed in an inclined or horizontal plane and moves in the track (52) of the longitudinal guide rail (5) without lateral movement, thereby ensuring the lateral stability of the cutting wheel (3) and the spacer (4) located in a laterally offset and asymmetrical vertical plane relative to the longitudinal guide rail (5).

[0041] Having fully described the features of this application and a preferred embodiment, it is hereby declared that modifications may be made to the material, shape, size, and arrangement of the described elements without altering the scope of protection claimed by this invention.
