Description

Technical Field

[0001] The invention relates to the field of manual tool manufacturing, in particular to a manual tile cutter. Background Art

[0002] The existing manual tile cutting machine includes: a base for supporting the tile to be cut, a cutting head that can move along a plurality of longitudinal guide rails fixed above the base and is manually controlled, and a combination angle square installed at one longitudinal end of the base, wherein the combination angle square forms a side support limiter for the tile to be cut.

[0003] Such machines require that the combination square be placed perpendicular to the cutting line defined by the cutting head as the cutting head moves along the longitudinal guide rail.

[0004] The misalignment of the combination square relative to the perpendicular to the cutting line may be caused by different reasons, for example, due to machine manufacturing defects during production, or external forces causing the position of the combination square to deform relative to its fixing point on the base.

[0005] In either case, the deviation of the combination square from the perpendicular to the cutting line will cause problems, especially for large cutting machines, where a small angular deviation may cause an error of several millimeters to accumulate on the side farthest from the combination square during the cutting process, causing the cut large slab of tile to be discarded because it is unusable, thereby wasting the operator's time and wasted materials.

[0006] The cutting machine of the prior art uses a complex, fragile, and inconvenient operating system to adjust the position of the combination square relative to the base, which leads to errors in calibrating the cutting machine, resulting in damaged parts and long adjustment time.

[0007] Another problem is that before using the cutting machine, the operator cannot visually confirm whether the combination square is perpendicular to the cutting line, which causes the above-mentioned cutting errors to occur frequently.

[0008] Therefore, a manual tile cutter is needed, which has technical features that can solve the above technical problems, especially, it can quickly, reliably and simply install the combination square to the relative position of the base, and the verticality can be confirmed visually. Summary of the invention

[0009] The manual tile cutting machine equipped with an adjustable combination angle ruler of the present invention comprises: a combination angle ruler installed on a longitudinal end of a supporting base to support the tile object to be cut, and a manually controlled cutting head, which can move along a plurality of longitudinal guide rails; the cutting machine has technical features that can solve the above-mentioned technical problems, and provides an appropriate way to quickly, reliably and simply adjust the combination angle ruler relative to the base position, and fix it after convenient adjustment.

[0010] To this end, according to the present invention, the manual tile cutting machine equipped with an adjustable combination square also includes an adjusting component for adjusting the verticality of the combination square relative to the cutting line of the cutting machine, and a fixing component for fixing the combination square to the base after convenient adjustment.

[0011] Therefore, any error of the combination square caused by reasons such as manufacturing error of parts can be calibrated through the adjustment and fixing components of the combination square, and errors in cutting of the tile object can be prevented.

[0012] According to the present invention, the cutting machine also includes a rotating shaft located on the combination square and arranged transversely relative to the base; and the fixing part of the combination square includes at least one fixing screw installed on the base of the cutting machine, and the fixing screw passes through the long hole on the combination square and the transverse rotating shaft of the combination square. Before the fixing screw is tightened, the rotating shaft can be rotated toward both sides of the base, thereby adjusting the verticality of the combination square relative to the cutting line of the cutting machine.

[0013] In the description of the present invention, the combination square is rotated laterally on the rotating shaft to achieve position adjustment; the combination square may include at least two long holes and be equipped with corresponding fixing screws to adjust the position of the combination square and make it perpendicular to the cutting line of the cutting machine.

[0014] In order to control the movement of the combination square relative to the base during the position adjustment process and ensure accurate calibration, the adjustment component includes: an elastic element acting on the combination square and guiding it to rotate toward one side of the base and a manually adjusted screw for controlling the combination square to rotate in the opposite direction of the elastic element.

[0015] Another technical feature of the present invention is that the cutting machine includes a visual confirmation component for confirming the perpendicularity of the combination square and the cutting line, so that the operator can visually judge whether the position of the combination square is perpendicular to the cutting line or whether the position of the combination square needs to be adjusted to make it perpendicular to the cutting line without using additional appliances or tools, thereby preventing errors in cutting the tile object.

[0016] According to the present invention, the visual confirmation component includes: a longitudinal mark located on the cutting machine base and parallel to the cutting line, and a visual indicator fixed on the combination square, when the combination square is perpendicular to the cutting line, the visual indicator is aligned with the longitudinal mark.

[0022] like Figure 1 As shown, the manual tile cutting machine equipped with an adjustable combination angle ruler comprises: an adjustable combination angle ruler (1) installed at one of the longitudinal ends of the base (2) to support the tile object to be cut, and a manually controlled cutting head (3), wherein the cutting head (3) can move along a plurality of longitudinal guide rails (4) fixed above the base (2) and arranged at intervals.

[0023] By moving the cutting head (3) along the guide rail (3), a longitudinal cutting line (L1) is obtained on the tile object (not shown) placed on the base (2), and the side surface of the tile object abuts against the support line (L2) formed by the front end of the combination square (1).

[0024] The cutting machine comprises a rotating shaft (5) located on the combination square (1) and arranged transversely relative to the base (2), and used for adjusting its verticality relative to the cutting line (L1).

[0025] The rotating shaft (5) is very close to the intersection of the cutting line (L1) of the cutting machine and the supporting line (L2) of the tile object against the combination square (1).

[0026] Figure 2 Shown is a fixing component for fixing the combination angle square (1) on the cutting machine base (2), wherein the fixing component is composed of a fixing screw (11) mounted on the cutting machine base (2) and passing through a long hole (12) on the combination angle square (1).

[0027] In the example shown, the combination square (1) includes four long holes (12) so that the combination square (1) can be rotated laterally relative to the rotating shaft (5), so that before tightening the screw (11) and fixing it relative to the base (2), the combination square (1) and the cutting line (L1) of the cutting machine are perpendicular to each other.

[0029] In this embodiment, the manually adjustable screw (14) and the elastic element (13) are mounted on the combination square (1) and act on a main rod (21) of the base (2). Figure 2 and Figure 4 As shown in the cross-sectional view in FIG. 1 , the main rod (21) is at the same position as the cutting line (L1) of the cutting machine.

When the combination square (1) is perpendicular to the cutting line (L1), the visual indicator (15) is aligned with the longitudinal mark (22).
