Description
Technical Field
[0001] The utility model belongs to the field of manual tile cutting machines, in particular to a manual tile cutting machine using a profile inlaid circular guide rail combined guide rail. Background Art
[0002] The structure of the existing manual tile cutter (referred to as the cutter) mainly includes a handle, a base plate, a guide rail, a slider and a cutter wheel. The guide rail has a square cross section. The guide rail is arranged parallel to the base plate through a bracket. The slider is slidably arranged on the guide rail. The guide rail passes horizontally through the slider. The handle is hinged to the slider. The rear end of the handle is a hand-held part, which is located above the guide rail. The front end of the handle is located below the guide rail and is provided with a rotatably connected cutter wheel. When in use, the tile is placed on the base plate, the hand-held part of the handle is pressed down, so that the cutter wheel contacts the tile, and the handle is pushed. The handle moves along the guide rail through the slider, driving the guide wheel to move along the tile, marking and cutting the tile.
[0003] In the existing cutting machine, the guide rail is made of solid steel as a whole, such as cut from long flat steel strips. The material is hard, and the raw material has high density, long length, and large overall weight. Not only is the processing difficult, but the cutting machine is also heavy and difficult to operate.
[0004] In existing cutting machines, in order to ensure the straightness of the guide rail, the guide rail needs to be ground. Affected by the processing accuracy, the cross-sectional size of the guide rail will have an error of several tens of wires, that is, a gap will be formed between the guide rail and the slide rail. In order to reduce the movement resistance of the slider and ensure the marking accuracy, bearings connected to the slider are set on all four sides of the guide rail, and springs are set between the bearings and the slider. The springs give pressure to the bearings to move inward so that the bearings fit the guide rails. The large number of springs required increases the difficulty of assembling the cutting machine and pushes up the production cost of the cutting machine.
[0005] Therefore, the existing cutting machines have the defects of being difficult to process, difficult to operate, difficult to assemble and having high production costs. Utility Model Content

[0012] In the aforementioned manual tile cutting machine using a profile inlaid with a circular guide rail combination guide rail, a reinforcing rib plate is provided at the bottom of the profile, and the reinforcing rib plate is located between the two lower circular guide rails.

DETAILED DESCRIPTION
[0027] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.
[0028] Embodiment 1. A manual tile cutting machine using a profile inlaid circular guide rail combined guide rail is improved on the basis of the existing cutting machine, including a handle 18, a bottom plate, a guide rail, a slide block 1 and a cutter wheel, etc. The guide rail is slidably connected to the slide block 1, and has the following characteristics: Figures 1 to 5 As shown,
[0029] The guide rail includes a hollow structure profile 2, the profile 2 is made of aluminum alloy, and two support ribs 17 are arranged inside the profile 2 in an eight-shaped arrangement inside the profile 2, and the upper and lower ends of the support ribs 17 are fixed to the profile 2. The bottom width of the profile 2 is inwardly recessed on both sides to form a bottom groove 3, and a lower circular guide rail 4 is penetrated in the bottom groove 3, and the bottom of the lower circular guide rail 4 is exposed outside the bottom groove 3, and the lower circular guide rail 4 is formed by cutting round steel.
[0030] The slider 1 is a U-shaped structure, the opening of the slider 1 is downward, the profile 2 passes through the slider 1, and two second bearings 6 are provided on the lower side of the lower circular guide rail 4. The second bearings 6 are respectively located directly below the lower ends of the two supporting ribs 17. The two second bearings 6 are respectively close to the front and rear sides of the slider 1. The second bearings 6 are connected to the slider 1 through the second pin shaft 16. The second bearing 6 is a U-shaped bearing, and the rolling arc surface of the second bearing 6 cooperates with the lower circular guide rail 4.
[0031] A first bearing 5 is provided on the inner side of the slider 1. The first bearing 5 is located directly above the upper end of the supporting rib 17. The first bearing 5 is located in the middle of the slider 1 in the front-to-back direction and the middle of the width direction. The first bearing 5 is a U-shaped bearing. The top of the profile 2 bulges upward to form a protrusion 7 with a circular arc surface. The rolling arc surface of the first bearing 5 cooperates with the top surface of the protrusion 7.
[0032] A reinforcing rib plate 10 is provided at the bottom of the profile 2. The reinforcing rib plate 10 is U-shaped and is located between the two lower circular guide rails 4. Both side plates of the reinforcing rib plate 10 are fixed to the profile 2. The reinforcing rib plate 10 and the supporting rib plate 17 are integrally formed on the profile 2 during the extrusion process.
[0033] The first bearing 5 is provided with a first pin 11 in the axial direction, the first pin 11 passes through the two side plates of the slider 1, the first pin 11 is clearance-matched with the slider 1, and both ends of the first pin 11 are provided with limit caps 12. The top of the slider 1 is provided with two adjustment holes 13, the two adjustment holes 13 are respectively located on both sides of the axial direction of the first bearing 5, a set screw 14 is provided in the adjustment hole 13, and a compression spring 15 connected to the first pin 11 is provided at the inner end of the set screw 14.
[0034] Working principle of embodiment 1: the compression spring 15 drives the first pin 11 to move downward, driving the first bearing 5 to press against the guide rail, and eliminating the gap between the guide rail and the slider 1 in the height direction. Since the rolling arc surface of the first bearing 5 matches the top surface of the protrusion 7, and the rolling arc surface of the second bearing 6 matches the lower circular guide rail 4, the slider is fixed in the upward position of the guide rail width, and the cutting machine will not bend when marking. The function of the compression spring 15 is to prevent the bearing from derailing.
[0035] The two supporting ribs 17 and the bottom plate of the profile 2 form a stable triangular supporting structure, which greatly increases the structural strength of the profile 2 and improves the bending resistance of the profile 2, which is beneficial to increasing the service life of the cutting machine.
[0036] like Figure 4 As shown, the first bearing 5 and the second bearing 6 form a triangular structure in the front view direction (i.e., the up and down direction), as shown in FIG. Figure 5 As shown, since the first bearing 5 and the second bearing 6 also form a triangular structure in the left viewing direction (i.e., the front-to-back direction), and in the top viewing direction (i.e., the left-to-right direction), the first bearing 5 and the two second bearings 6 on the two lower circular guide rails 4 respectively form two triangular structures, so that the guide rails and the slider 1 have good structural stability, which can ensure the use accuracy of the cutting machine.
[0037] In Example 1, a hollow aluminum profile is used as the guide rail body, and the lower circular guide rail 4 of the guide rail friction part is tightly rolled into the bottom groove 3. On the basis of ensuring the strength accuracy of the guide rail, the weight of the guide rail is greatly reduced, and by utilizing the high precision and high straightness of the profile itself, no secondary grinding is required, and the cost is also greatly reduced.
[0038] Embodiment 2. Different from Embodiment 1, the top of the profile 2 is recessed inward to form a top groove 8, and an upper circular guide rail 9 matching with the first bearing 5 is inserted into the top groove 8. The top of the upper circular guide rail 9 is exposed outside the top groove 8. The upper circular guide rail 9 is formed by cutting round steel, and the upper circular guide rail 9 is tightly pressed into the top groove 8 by a roller. The rolling arc surface of the first bearing 5 matches with the top surface of the upper circular guide rail 9.
[0039] Compared with Example 1, the upper circular guide rail 9 is used in Example 2 to replace the protrusion 7 in Example 1. The advantage of Example 2 is that the top of the profile 2 has better wear resistance and longer service life, but relatively more assembly steps are required. In Example 1, the protrusion 7 is integrally formed with the profile 2, reducing the number of assembly steps.
