Description

Technical Field

[0001] The utility model relates to the field of cutting equipment, in particular to a slide rail assembly for a cutting machine. Background Art

[0002] The tabletop cutting machine is a commonly used plate cutting equipment in the plate processing industry. It is used for flush cutting of ceramic tiles. It includes a tabletop, a slide rail above the tabletop and a cutting head mounted on the slide rail. The tabletop is provided with a limiter, and the plate is cut by driving the cutting head to move on the plate.

[0003] The existing slide rails usually adopt the form of pulleys, which use rollers to engage with the rails for movement. After long-term use, the rollers themselves wear greatly and the wear occurs in multiple parts such as the axis and surface. After long-term use, shaking and twisting occur, causing the overall accuracy to become very poor. A better method will be to use linear rails. In the linear rail method, the slider and the slide rail are matched through balls. This form with a small sliding contact surface has good linear accuracy in a low-vibration working environment, but the slider of the linear rail is directly fixed to the cutting machine head. After long-term use, the high-speed rotation of the saw blade and the vibration generated by cutting can easily cause the slide rail to shake and twist, resulting in misalignment and random displacement of the contact surface, which reduces the accuracy of the cutting head moving on the slide rail. In addition, both forms cannot further adjust the matching clearance of the slider after loosening and can only be replaced. Therefore, it is necessary to design a stable slide rail to solve the problems existing in the existing slide rails for cutting machines. Utility Model Content

[0004] In view of the above problems, the utility model provides a slide rail assembly for a cutting machine, which structure includes a rail member and a slider member slidably equipped with the rail member, wherein the rail member is provided with an inner groove recessed inwardly, and rail parts are provided on both sides of the inner groove, and the slider member slides with the rail parts of the inner groove; the slider member includes a base and a movable block detachably mounted on the base, the base and the movable block are provided with mating surfaces engaged with the rail parts on the outer sides, and a sliding layer for contact cooperation is provided on the mating surfaces; an adjustment block is provided between the base and the movable block for adjusting the distance between the mating surfaces on both sides of the base and the movable block, and a reference surface is provided on the base, and the movable block cooperates with the base with the reference surface as a contact reference.

[0005] Furthermore, the track portion is convex on the inner wall of the inner groove, and the matching surface matching therewith is concave on the base and the movable block; the convex track portion has at least two planes or one curved surface for contacting with the matching surface.

[0006] Furthermore, the sliding layer is a solid self-lubricating material, and the sliding layer is melted onto the matching surfaces of the base and the movable block to form a structural layer.

[0007] Furthermore, the cross-section of the track portion is triangular or trapezoidal and has two planes at the upper and lower ends that contact the mating surface, and a recessed clearance groove is provided in the middle of the contact surface to avoid the contact between the upper and lower planes of the track portion.

[0008] Furthermore, a vertical wall structure is provided on one side of the reference plane close to the mating surface of the base, the adjusting block is installed between the wall structure and the movable block, the outer surface of the wall structure and the back surface of the movable block are both inclined, and the two surfaces of the adjusting block in contact with the wall structure and the movable block are both inclined; the adjusting block and the movable block are connected to the base by bolts, and the movable block moves outward on the reference plane when the adjusting block is driven by the bolts to move downward.

DETAILED DESCRIPTION

[0019] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] Examples, such as Figure 1-Figure 3 As shown: The utility model provides a slide rail assembly for a cutting machine. For the cutting machine, the structure of the slide rail assembly includes a track member 1 and a slider member 2 slidably equipped with the track member 1. The track member 1 is used as a guide structure to allow the slider member 2 to carry the machine head and slide on the track member 1;

[0021] Specifically, the track member 1 is provided with an inner groove 1a which is recessed inwards, and track portions 1b are provided on both sides of the inner groove 1a. The top surface of the inner groove 1a does not directly contact the top of the track member 1, but a transverse structural beam is provided to connect the front and rear ends of the track member 1 to increase the strength of the track member 1. The slider member 2 is slidably matched with the track portion 1b of the inner groove 1a. When in use, the inner groove 1a opens downward, and the slider member 2 is assembled from the bottom to the inside of the track member 1. The slider member 2 includes a base 21 and a movable block 22 detachably mounted on the base 21. The base 21 is provided with a reference surface 21a, and the movable block 22 uses the reference surface 21a as a contact reference with the base 21. The base 21 is matched with each other, and a matching surface 2a that is engaged with the track portion 1b is provided on the outer side of the base 21 and the movable block 22, and a sliding layer 2b for contact matching is provided on the matching surface 2a. An adjustment block 23 is provided between the base 21 and the movable block 22 for adjusting the distance between the matching surfaces 2a on both sides of the base 21 and the movable block 22. By setting the opening of the inner groove 1a of the track member 1 to the top surface, the cables and other parts on the top surface of the track member 1 will not affect the track portion 1b and the slider member 2 on the inner side of the track member 1, and the slider member 2 is set in an assembled form, which is not only convenient for installation and adjustment, but also convenient for replacement;

[0022] In this embodiment, a vertical wall structure is provided on one side of the reference surface 21a close to the mating surface 2a of the base 21, which is used to connect to the part where the mating surface 2a is located, so as to form a base 21 with sufficient strength. The adjusting block 23 is installed between the wall structure and the movable block 22. The outer surface of the wall structure and the back surface of the movable block 22 are both inclined. The two surfaces of the adjusting block 23 that contact the wall structure and the movable block 22 are both inclined, and the adjusting block 23 and the movable block 22 are connected to the base 21 by bolts. Therefore, when the adjusting block 23 is driven by the bolts to move downward, the movable block 22 moves outward on the reference surface 21a, thereby increasing the distance between the mating surfaces 2a on both sides, so as to be installed in the track member 1.

[0023] In this embodiment, the track portion 1b is convex on the inner wall of the inner groove 1a, and the matching surface 2a matched therewith is concave on the base 21 and the movable block 22, and the convex track portion 1b has at least two planes or one curved surface for contacting with the matching surface 2a, that is, the convex track portion 1b can be semicircular, triangular or trapezoidal in cross section, etc.;

[0024] In this embodiment, the track portion 1b has a triangular or trapezoidal cross section and has two planes at the upper and lower ends that contact the mating surface 2a. The slider 2 slides on the track portion 1 by fitting the mating surface 2a against the two planes of the track portion 1b. Moreover, a recessed clearance groove is provided in the middle of the contact surface to avoid the contact portion of the upper and lower planes of the track portion 1b, thereby ensuring that no unnecessary friction is generated between the upper and lower contact surfaces and the track portion 1b. For example, the track portion 1b has a triangular cross section and the upper and lower mating surfaces 2a are directly connected. When in contact, the sharp portion of the front end of the triangle will hit the connection of the mating surfaces 2a, thereby increasing the wear of the sharp portion and making it easy for one of the two mating surfaces 2a to be out of contact. For this reason, the clearance groove can avoid the sharp portion.

[0025] At the same time, the sliding layer 2b is a solid self-lubricating material. The sliding layer 2b can be a material with a certain thickness that is installed on the mating surface 2a through welding, fusion, etc., or it can be coated on the mating surface 2a to form a self-lubricating material layer. In this embodiment, the sliding layer 2b is melt-coated on the mating surface 2a of the base 21 and the movable block 22 to form a structural layer. Solid self-lubricating materials known to those skilled in the art include certain engineering plastics used to make integral parts, such as polytetrafluoroethylene, polyacetal, polyformaldehyde, polycarbonate, polyamide, polysulfone, polyimide, chlorinated polyether, polyphenylene sulfide and polyester terephthalate, etc., which have a low friction coefficient, good forming processability and chemical stability. When in contact with the track portion 1b, the self-lubricating material can slide on the track portion 1b through its wear resistance and self-lubricating properties. In this way, the slider member 2 can cooperate with the track portion 1b in the form of surface contact, thereby obtaining a larger sliding cooperation contact surface to obtain a more stable cooperation effect, making the sliding process smoother.

[0026] In this embodiment, a plurality of grooves perpendicular to the length direction of the track portion 1b are provided on the surface where the mating surface 2a contacts the track portion 1b, and the sliding layer 2b is divided into a plurality of blocks by the grooves, which can increase the adaptability to the contact surface and also allow the sliding layer 2b to obtain a certain heat dissipation space. When technical personnel in this field need to increase the lubricating oil, the lubricating oil can be stored in the sliding layer 2b through the grooves.

[0027] During the specific implementation, the track member 1 is installed on the equipment, and then the adjusting block 23 is connected to the base 21 by bolts, and then the matching surface 2a of the base 21 is aligned with a track portion 1b of the inner groove 1a of the track member 1, so that the sliding layer 2b is attached thereto, and the entire base 21 is raised to a horizontal level, and then at the track portion 1b on the other side, the movable block 22 is inserted from the side of the base 21 between the base 21, the adjusting block 23 and the track portion 1b, and then the bolts of the adjusting block 23 are tightened so that the movable block 22 and the track portion 1b are abutted to the required tightness, and then the movable block 22 is pre-fixed with the base 21 by bolts, and then tightened after being adjusted to the required horizontal degree, so that the slider member 2 can slide on the track member 1, and a more stable sliding effect can be obtained through large-area contact, and a self-lubricating sliding layer 2b is used for sliding friction contact, so that there is good lubricity contact between the slider member 2 and the track member 1;

[0028] In this embodiment, a lower head mounting surface 21b is provided at the bottom end of the base 21, and upper head mounting surfaces 21c are provided on both sides of the base 21, thereby fixing the head including the controller downward from the top of the track member 1 to both sides of the base 21. Thanks to the downward opening of the inner groove 1a of the track member 1, the cables and other parts on the top surface of the track member 1 will not affect the track portion 1b and the slider member 2 on the inner side of the track member 1. Then, the cutting knife part is fixed to the bottom surface of the base 21, and then the track member 1 is installed on the cutting equipment. After the driving structure and circuit are connected, it can be used.

[0029] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
