Background Art

[0002] The prior patent CN 101456223B of the present application, named "special sliding rod carriage for tile cutting machine", includes a sliding rod carriage, which is characterized in that: the rail surfaces on both sides of the sliding rod are structurally designed to be isosceles open trapezoids, and the roller surfaces of the bearings on the upper inclined surface and the lower inclined surface of the angle respectively coincide with the isosceles open trapezoidal inclined surfaces on both sides of the sliding rod, and the sliding rod carriage frame in the sliding rod carriage is in a main view of two angles relative to each other, the upper part is connected as a whole, and the lower part is open, and the upper inclined surface and the lower inclined surface constituting each of the two angles are respectively provided with 2 or more bearings, and the roller surfaces of the bearings on the upper inclined surface and the lower inclined surface are staggered, and the two sides constituting each of the two angles are composed of an upper inclined surface and a lower inclined surface, and the angle α of each angle in the two angles is 80°~100°, and the end of the sliding rod carriage connected to the handle head is a groove, and the two walls of the groove are provided with relative axial holes. This patent is mainly used for I-shaped slide rails, and the upper and lower surfaces of the two side surfaces of the I-shaped slide rails need to be inclined. The manufacturing difficulty is relatively large, and it is relatively difficult to ensure the consistency of precision. It is difficult to achieve a gap-free fit between the slide frame and the slide rail. Summary of the invention

[0003] Design purpose: To avoid the shortcomings of the background technology, a new single-rail slide for tile cutting machines is designed, which can not only realize the gapless fit between the slide and the slide rail in a fool-proof assembly, but also effectively improve the cutting efficiency, cutting accuracy, cutting quality, and is easy to operate.

[0004] Design scheme: In order to achieve the above design objectives. 1. The design that the left slide housing and the right slide housing are respectively provided with three-point bearings with a triangular distribution is one of the technical features of the present invention. The purpose of such a design is: since the three-point bearings with a triangular distribution refer to a single bearing located in the middle of the pin shaft and two bearings located at both ends of the pin shaft that are distributed in a triangular shape, that is, three points determine a plane, according to the principle of "three points determine a plane", three fulcrums (bearings) are used to ensure that the slide and the slide rail are on the same plane, thereby achieving precise matching and stable sliding without gaps between the slide and the slide rail surface. 2. The design of the plastic pin shaft seat being clamped on the pin shaft is the second technical feature of the present invention. The purpose of such design is: since the bayonet surface of the plastic pin seat is provided with a groove and the outer side of the groove wall is arc-shaped and the plastic pin seat is elastic, the arc shape is not only conducive to the slight deformation of the plastic pin seat after being subjected to force, but also reduces the contact area with the slide rail surface, ensures the plane contact between the plastic pin seat and the slide rail surface, and at the same time serves the purpose of assisting the positioning of the pin; secondly, by utilizing the elasticity of the plastic pin seat and the slight deformation of the plastic pin seat after being subjected to the force between the slide housing and the slide rail, the tolerance and assembly error of the spare parts are eliminated, the gap between the left and right sides of the slide is eliminated, and the purpose of fool-proof assembly and no gap between the left and right sides of the slide is achieved, thereby effectively improving the cutting accuracy. 3. The design of the one-line distribution of the front and rear bearings in the upper and lower parts of the slide housing cavity is the third technical feature of the present invention. The purpose of this design is: since the front and rear bearings are distributed in a straight line, that is, two bearings are located on the pin shaft, one in front and one behind, and move on the upper and lower surfaces of the slide rail, while ensuring that there is no gap between the upper and lower parts of the slide. Because of all the bearings, it can be well ensured that the slide can move smoothly and without gaps, effectively improving the cutting accuracy.

[0005] Technical solution: A new type of single-track slide for a tile cutting machine, including a left slide shell and a right slide shell, the left slide shell and the right slide shell constitute a slide frame shell, and the left slide shell and the right slide shell are respectively provided with three-point bearings with triangular distribution, and the three-point bearings ensure that the left slide shell and the right slide shell are on the same plane with the slide rail.

[0006] Compared with the background technology, the present invention, firstly, realizes the gapless fit between the slide and the slide rail in a fool-proof assembly; secondly, effectively improves the cutting efficiency, cutting accuracy, cutting quality, and facilitates operation while reducing the manufacturing cost and assembly difficulty.

[0012] Example 1: Refer to the attached Figure 1-5 . A new type of single-track slide for a tile cutting machine includes a left slide shell 1 and a right slide shell 2, which are connected to each other by screws 5 and nuts 12 to form a slide shell, and three-point bearings 7 and 8 distributed in a triangle are respectively provided in the left slide shell 1 and the right slide shell 2, and the three-point bearings ensure that the left slide shell 1 and the right slide shell 2 are on the same plane with the slide rail 3. The mating surfaces of the two sides of the slide rail 3 and the three-point bearings 7 and 8 are flat. The three-point bearings 7 and 8 distributed in a triangle refer to a single bearing 7 located in the middle of the pin shaft and two bearings 8 located at both ends of the pin shaft, which are distributed in a triangle. The plastic pin shaft seat 6 is clamped on the pin shaft. The pin shaft buckle 9 is used to fix the pin shaft, and the specific structure is shown in Figure 4 . A groove 6-1 is formed on the bayonet surface of the plastic pin seat 6, and the outer side of the groove wall is in an arc shape 6-2, and the open end face of the groove wall is a plane 6-3. The upper and lower parts of the housing cavity of the carriage housing are respectively provided with front and rear bearings 10 and 11 distributed in a straight line, and the front and rear bearings distributed in a straight line are respectively matched with the upper and lower surfaces of the slide rail 3 without clearance.
