Abstract
Description
Technical Field
[0001] This utility model relates to a track pusher, and more particularly to a three-point positioning track pusher. Background Technology
[0002] As a core decorative material in home decoration, kitchen and bathroom renovation, and small commercial projects, the cutting precision of tiles directly determines the aesthetics, sealing, and structural stability after installation. Especially in scenarios such as whole-house tiling, splicing of inside and outside corners, and finishing of irregular openings, the straightness error needs to be strictly controlled during the tile cutting process. Otherwise, problems such as uneven gaps, misaligned splicing, and chipped edges and corners are likely to occur, seriously affecting the construction quality.
[0003] Manual tile cutters have become the mainstream choice for home decoration and small-scale construction projects due to their advantages such as environmental friendliness, portability, and low operating costs. Among them, the track-guided cutter, as an advanced version of the manual tile cutter, guides the blade through a metal track, which improves cutting accuracy compared to traditional trackless manual cutters. Existing track-guided cutters mostly use a single-rail or simple double-rail structure, with a rigid fit between the slider and the track. This results in inaccurate positioning, and over time, wear on the track and slider further widens the gap, leading to a gradual deterioration of the error and affecting tile cutting accuracy. Utility Model Content
[0004] The purpose of this invention is to provide a three-point positioning track pusher. It improves the stability of the slider during operation through three-point positioning, and the use of round steel and U-shaped bearings enhances wear resistance.
[0005] The technical solution of this utility model is as follows: a three-point positioning track pusher, comprising: a track assembly and a pusher assembly movable relative to the track assembly. The pusher assembly includes a slider seat, with a horizontal mounting surface and a vertical mounting surface on the lower side of the slider seat. One or more sets of rollers are provided on the vertical mounting surface via a mounting assembly. The roller sets include a first roller and a second roller located at different heights on the vertical mounting surface. One or more sets of third rollers are provided on the lower side of the horizontal mounting surface via a mounting assembly. A cutting assembly is provided on the upper side of the slider seat.
[0006] In the aforementioned three-point positioning track pusher, the number of roller groups is greater than two, and the roller groups are distributed in a linear symmetrical array.
[0007] In the aforementioned three-point positioning track pusher, there are two sets of rollers, which are symmetrically distributed around the center of the slider seat.
[0008] In the aforementioned three-point positioning track pusher, the mounting assembly includes an eccentric nut and a set screw disposed on a horizontal mounting surface and a vertical mounting surface. One side of the eccentric nut is provided with a washer and a fixing screw for fixing the first roller, the second roller and the third roller.
[0009] In the aforementioned three-point positioning track pusher, the first roller, the second roller, and the third roller are U-shaped bearings.
[0010] In the aforementioned three-point positioning track pusher, the track assembly includes a track body, which has a guide groove and a mounting groove arranged in the length direction. The guide groove has round steel corresponding to the first roller, the second roller and the third roller, and the mounting groove has a mounting nut, which has a hand-tightening screw.
[0011] In the aforementioned three-point positioning track pusher, the track body has pin holes at both ends, and the pin holes are equipped with fixing pins for connecting adjacent track bodies.
[0012] In the aforementioned three-point positioning track pusher, the fixing pin is a knurled pin.
[0013] In the aforementioned three-point positioning track pusher, the number of pin holes is three sets.
[0014] In the aforementioned three-point positioning track pusher, the number of the third rollers is the same as the number of roller sets.
[0015] Compared with the prior art, the present invention has the following advantages: This application improves the stability of the pusher assembly during operation by setting the first, second, and third rollers to cooperate with the round steel in the track assembly. Furthermore, the U-shaped bearing and the round steel have good wear resistance, which reduces the error caused by wear of the track pusher during long-term operation. The length of the track assembly can be adjusted by the cooperation of the pin hole and the fixing pin, which makes it more applicable and easier to transport. Attached Figure Description

Detailed Implementation
[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.
[0019] Example 1. A three-point positioning track pusher, configured as follows: Figure 1-4 As shown, it includes: a track assembly 1 and a pusher assembly 2 that can move relative to the track assembly 1.
[0020] The pusher assembly 2 includes a slider seat 2.1. The slider seat 2.1 has a horizontal mounting surface 2.2 and a vertical mounting surface 2.3 on its lower side. A set of rollers 2.4 is provided on the vertical mounting surface 2.3 through a mounting assembly. The rollers 2.4 include a first roller 2.5 and a second roller 2.6 located at different heights on the vertical mounting surface 2.3. A third roller 2.7 is provided on the lower side of the horizontal mounting surface 2.2 through a mounting assembly. A cutting assembly 2.8 is provided on the upper side of the slider seat 2.1.
[0021] The mounting assembly includes an eccentric nut 3 and a set screw 4 disposed on the horizontal mounting surface 2.2 and the vertical mounting surface 2.3. The eccentric nut 3 has a washer 5 and a fixing screw 7 on one side for fixing the first roller 2.5, the second roller 2.6 and the third roller 2.7.
[0022] The first roller 2.5, the second roller 2.6 and the third roller 2.7 are U-shaped bearings 6.
[0023] The number of the third roller 2.7 is the same as the number of roller sets 2.4.
[0024] The track assembly 1 includes a track body 1.1, in which a guide groove 1.2 and a mounting groove 1.6 are provided along the length direction. The guide groove 1.2 is provided with round steel 1.3 corresponding to the first roller 2.5, the second roller 2.6 and the third roller 2.7. The mounting groove 1.6 is provided with a mounting nut 1.7 and a hand-tightening screw 1.8.
[0025] The track body 1.1 has pin holes 1.4 at both ends, and the pin holes 1.4 are provided with fixing pins 1.5 for connecting adjacent track bodies 1.1.
[0026] The fixing pin 1.5 is a knurled pin.
[0027] The number of pin holes 1.4 is 3 sets.
[0028] The principle of this utility model: The track assembly 1 of this application can be composed of multiple sets of track bodies 1.1. The track bodies 1.1 are connected by fixing pins 1.5 and pin holes 1.4. There are 3 sets of pin holes 1.4 and fixing pins 1.5, which improves the positioning effect and avoids misalignment during splicing, resulting in curved lines. The pusher assembly 2 can move along the track assembly 1 to cut the tiles. This application can achieve three-point positioning through the combined action of the first roller 2.5, the second roller 2.6, and the third roller 2.7, so that the error of the pusher assembly 2 is small when it moves. The setting of the eccentric nut 3 can eliminate the gap between the slider seat 2.1, the U-shaped bearing 6 and the round steel 1.3, making the movement of the pusher assembly 2 along the track assembly 1 smoother and more straight, and the lines drawn by the cutting wheel are more accurate. The use of round steel 1.3 and U-shaped bearing 6 can improve the wear resistance of this application, avoid the increase of error due to wear during long-term use, and make the tile cutting quality better.
[0029] Example 2. Based on Example 1, the number of roller groups 2.4 is greater than two groups, and the roller groups 2.4 are distributed in a linear symmetrical array.
[0030] Example 3. Based on Example 1, the number of roller sets 2.4 is two sets, and the two sets of roller sets 2.4 are symmetrically distributed around the center plane of the slider seat 2.1.
[0031] Example 4. Based on Example 1, the number of roller sets 2.4 is greater than or equal to two sets, and the roller sets 2.4 are parallel to each other.
