TOOLHOLDER GUIDE SYSTEM IN MANUAL CERAMIC CUTTERS

Abstract

A toolholder guide system in manual ceramic cutters, including parallel guides for the longitudinal movement of a toolholder that has a handle for the actuation thereof and carries a cutting tool for scoring a ceramic part. The guides are formed by a profile, for example made of aluminium, each guide having upper and lower steel rods, disposed longitudinally, forming races for bearing carriages disposed on the sides of the toolholder. Each bearing carriage has two end bearings disposed at the same height and at least one intermediate bearing disposed at a lower height than the two end bearings.

1-3. (canceled)

4. A toolholder guide system in manual ceramic cutters, comprising parallel guides for longitudinal movement of a toolholder that comprises a handle for the actuation thereof and carries a cutting tool for scoring a ceramic part; wherein the guides are formed by a profile, made of aluminium; each guide comprising upper and lower steel rods, disposed longitudinally, forming races for bearing carriages disposed on the sides of the toolholder; each bearing carriage comprises two end bearings disposed at the same height, which come in contact with the upper steel rod of the guide corresponding to the same side, and at least one intermediate bearing disposed at a lower height than the two end bearings, which comes in contact with the lower steel rod of the corresponding guide.

5. The guide system according to claim 4, wherein the profile forming the guides has an overall C shape, the steel rods being disposed between wings defined by said profile.

6. The guide system, according to claim 1, wherein the guides incorporate steel bars with an increased resistance to bending.

Description

DESCRIPTION OF THE FIGURES

[0014] As a complement to the description provided herein, and for the purpose of helping to make the characteristics of the invention more readily understandable, the present specification is accompanied by a set of drawings, which, by way of illustration and not limitation, represent the following:

[0015] FIG. 1 shows a partial perspective view and cross section of an exemplary embodiment of the toolholder guide system in manual ceramic cutters according to the invention.

[0016] FIG. 2 shows an elevation view of the guide system of the previous figure.

PREFERRED EMBODIMENT OF THE INVENTION

[0017] In the embodiment shown in the attached figures, the toolholder (1) has an actuation handle (11) and, as is common in ceramic cutter machines, it carries a cutting tool (12) and a separator (13) for ceramic parts already scored with the cutting tool.

[0018] The toolholder guide system (1) comprises two parallel guides (2) formed by an aluminium profile in a general C shape and disposed to face each other, each of the guides (2) comprising a pair of upper and lower steel rods (21, 22), disposed longitudinally and located between wings defined by the aforementioned profile (2); said steel rods (21, 22) forming races for bearing carriages (3) mounted on the sides of the toolholder (1).

[0019] As can be observed in FIG. 1, each bearing carriage (3) comprises two end bearings (31, 32) disposed at the same height and that come in contact with the upper steel rod (21) of the guide (2) corresponding to the same side, and an intermediate bearing (33) disposed at a lower height and that comes in contact with the lower steel rod (22) of the corresponding guide (2).

[0020] In the exemplary embodiment shown in the attached figures, the aluminium profile forming the guides (2) incorporates steel bars (23) in the inside thereof in order to increase the resistance to bending of the guides, especially in large cutters.

[0021] Having sufficiently described the nature of the invention, in addition to an example of a preferred embodiment, it is hereby stated for the relevant purposes that the materials, shape, size and layout of the described elements may be modified, provided that it does not imply altering the essential characteristics of the invention claimed below.
