Description

Technical Field

[0001] The utility model relates to the field of production and processing of tile cutting machines, in particular to a guide rail straightness measuring tool for a manual tile cutting machine. Background Art

[0002] Ceramic tiles are a type of acid- and alkali-resistant porcelain or stone material used in construction or decoration, made from refractory metal oxides and semi-metal oxides through a process of grinding, mixing, pressing, glazing, and sintering. Ceramic tiles are produced in relatively large sizes, and are subsequently cut into corresponding sizes using a tile cutter based on the actual needs. There are two types of tile cutters: automatic and manual. Automatic tile cutters are relatively expensive, heavy, and have limited space requirements. Therefore, many people choose manual tile cutters.

[0003] The guide rail of a manual tile cutting machine is one of the indispensable components for guiding and supporting the movement of the tile marking and breaking mechanism. If the straightness of the guide rail is insufficient, the size of the tile will not meet the requirements after marking and breaking, resulting in a low yield rate and waste of tiles. However, it is difficult to identify the straightness of the existing guide rails during incoming materials and assembly. Conventional methods use three-coordinate measurement, but the measurement efficiency of the three-coordinate measuring instrument is relatively low, so only random inspections can be carried out on each batch of incoming materials. The longest length of the guide rail is 1800mm. The guide rail is made by aluminum extrusion. The 1800mm and 0.5 straightness guide rails made by the existing aluminum extrusion die have insufficient straightness, which leads to large cutting arcs or even out-of-tolerance problems after assembly, which affects the cutting experience and assembly efficiency. Therefore, how to quickly measure each guide rail is a direction that technicians in this field need to work on. Summary of the Invention

[0004] The purpose of the utility model is to provide a guide rail straightness measuring fixture for a manual tile cutting machine. By using this structure, the rapid measurement of the guide rail straightness is improved, thereby ensuring the quality of the tile cutting machine, further improving the tile marking and cutting effect, increasing product yield, and reducing construction costs.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a guide rail straightness measuring fixture for a manual tile cutting machine, including a reference platform, a slide rail, a slider and a universal micrometer. The slide rail is installed on the reference platform, the front end surface of the reference platform is arranged parallel to the slide rail, the slider is slidably set on the slide rail, the universal micrometer is detachably installed on the slider, and the guide rail to be measured is installed on the front end surface of the reference platform.

[0006] In the above technical solution, there are two sliders, and a universal micrometer can be installed on each slider.

[0007] In the above technical solution, two rows of screw holes are provided at intervals in front and back on the top of the reference platform, which are first screw holes and second screw holes respectively. Multiple first screw holes are arranged at intervals from left to right, and multiple second screw holes are arranged at intervals from left to right. The first screw holes are arranged in front of the second screw holes; the slide rail is installed on the reference platform through bolts and multiple first screw holes or second screw holes.

[0008] In the above technical solution, a plurality of positioning screw holes are provided on the front end surface of the reference platform, and the plurality of positioning screw holes are spaced from left to right. The guide rail to be measured is detachably mounted on the front end surface of the reference platform via positioning bolts and the positioning screw holes.

[0009] In the above technical solution, the guide rod to be measured is located on the front end surface of the reference platform through a quick clamp.

[0010] In the above technical solution, a stop bolt is provided on each of the side walls or the top of the slide rail, and the slide block is arranged between the two stop bolts.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0018] Example 1: See Figure 1 、 2 As shown, a guide rail straightness measuring fixture for a manual tile cutting machine includes a reference platform 1, a slide rail 2, a slider 3 and a universal micrometer 4. The slide rail 2 is installed on the reference platform 1, and the front end surface of the reference platform 1 is arranged parallel to the slide rail 2. The slider 3 is slidably set on the slide rail 2, and the universal micrometer 4 is detachably installed on the slider 3. The guide rail 5 to be measured is installed on the front end surface of the reference platform 1.

[0019] In this embodiment, the slide rail is a slide rail with high straightness accuracy that has been pre-processed and tested. It is installed on the reference platform, and the slider is slidably set on the slide rail. Then the universal micrometer is installed on the top of the slider. When the guide rail to be measured needs to be tested, the guide rail to be measured is installed on the front end surface of the reference platform. Since the front end surface of the reference platform is parallel to the slide rail, when the guide rail to be measured is installed on the front end surface of the reference platform, the side wall of the guide rail to be measured is against the front end surface of the reference platform. At this time, the front end surface of the guide rail to be measured is equivalent to the guide rail installation position of the tile cutting machine, and the front end surface of the reference platform is used as the base. Accurate, then after the universal micrometer is reset to zero, the test end of the universal micrometer is placed on one of the side surfaces of the guide rail to be measured, and then the slider is moved on the slide rail to drive the universal micrometer to move, so that the universal micrometer and one side surface of the guide rail to be measured move and contact, until the universal micrometer and one side surface are in contact, the detection of one side surface of the guide rail to be measured can be completed. During the process of the universal micrometer and one side surface of the guide rail to be measured, the inspector observes the value of the universal micrometer to determine whether the straightness of the side surface is qualified (whether the deformation range is within the predetermined range). After the detection of one side surface is completed, the end of the universal micrometer contacts the other side surface, and the universal micrometer is reset to zero at the same time, and then the above action is repeated for rapid testing. This cycle is repeated until the rapid measurement of multiple sides is completed, thereby quickly identifying whether the guide rail to be measured is qualified. If the straightness of a certain working sliding surface of the guide rail is insufficient, it can be reworked until it is qualified, which can reduce costs.

[0020] See also Figure 1 、 2 As shown, the sliders 3 are two pieces, and a universal micrometer 4 can be installed on each slider 3.

[0021] In this embodiment, two sliders are provided, so that a universal micrometer can be installed on each slider. In this way, two operators can move from the two ends of the slide rail to be measured toward the middle of the guide rail to be measured and perform measurements at the same time. In this way, the measurement efficiency is high.

[0022] See also Figure 2 As shown, the top of the reference platform 1 is provided with two rows of screw holes spaced apart from each other, namely, first screw holes 6 and second screw holes 7. The first screw holes 6 are spaced apart from each other from left to right, and the second screw holes 7 are spaced apart from each other from left to right. The first screw holes 6 are located in front of the second screw holes 7. The slide rail 2 is mounted on the reference platform 1 via bolts 8 and the first screw holes 6 or the second screw holes 7. The diameter of the first screw holes is different from the diameter of the second screw holes.

[0023] In this embodiment, two rows of screw holes are provided, and slide rails of corresponding widths can be installed according to actual conditions. The slide rails can be connected to the first screw holes through bolts, or they can be connected to the second screw holes through bolts. The installation can be performed according to the bolts that match the corresponding slide rails.

[0024] At the same time, in the present invention, the length of the slide rail can be less than the length of the reference platform, or greater than the length of the reference platform. Preferably, the length of the reference platform is greater than 1800 mm, and the length of the slide rail is greater than the longest length of the guide rail to be measured, that is, the length of the slide rail will be greater than 1800 mm, so that guide rails of different lengths to be measured can be detected.

[0025] Among them, a plurality of positioning screw holes 9 are provided on the front end surface of the reference platform 1, and the plurality of positioning screw holes 9 are spaced from left to right. The guide rail 5 to be measured is detachably installed on the front end surface of the reference platform 1 through the positioning bolts 10 and the positioning screw holes 9.

[0026] In this embodiment, a positioning screw hole is provided on the front face of the reference platform, and the side wall of the guide rail to be measured is against the front face of the reference platform. The guide rail to be measured has a hole position for installation and fixing, and multiple holes are directly opposite the positioning screw holes. Then, positioning bolts are passed through the holes and connected with the positioning screw holes to quickly fix the guide rail to be measured and the reference platform. In this way, at least three positioning bolts can be installed. If only three positioning bolts are used, two of them are located at the ends of the guide rail to be measured, and one is located in the middle of the guide rail to be measured. In this way, the three bolts can stably limit the position of the guide rail to be measured on the front face of the reference platform, and the restricted position of the guide rail to be measured is more balanced, preventing measurement defects of the guide rail to be measured caused by installation problems (if multiple positioning bolts are used to limit the left end to the middle of the guide rail to be measured, and its right end is not limited by a positioning bolt, the right end of the guide rail to be measured may be deformed by weight, thereby causing measurement failure of the guide rail to be measured; or if the ends of the guide rail to be measured are fixed and the middle is not fixed, the middle part may also be deformed, resulting in measurement failure).

[0027] More preferably, a stop bolt (not shown) is provided on each sidewall or top of the slide rail, and the slider is positioned between the two stop bolts. The stop bolts are provided to limit the slider's movement, preventing the slider from falling off the slide rail or tipping over due to operator error, potentially damaging the micrometer, or causing the slider to shift relative to the slide rail due to damage to the slider, thereby affecting measurement accuracy.

[0028] Example 2: A guide rail straightness measurement system for a manual tile cutter. This example's structure is similar to that of Example 1, differing in that the guide rail to be measured is secured to the front face of the reference platform via a quick-release clamp. This method uses a quick-release clamp to connect the guide rail to the reference platform, facilitating quick installation and removal.

[0029] In the description of the present invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," "outer," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In the description of the present invention, "plurality" means two or more, unless otherwise expressly and specifically defined.

[0030] In this utility model, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, they can be fixedly connected, detachably connected, or integrated; they can be mechanically connected or electrically connected; they can be directly connected or indirectly connected through an intermediate medium. For example, the two can be connected by abutting or touching to form a mechanical abutment or abutment. The two can also be directly hung or hung through an intermediate medium. It can also be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this invention can be understood according to specific circumstances.
