Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, specifically to a fixed fixture for a high-precision laser cutting machine. Background Technology

[0002] Laser cutting is a common cutting technology in machine tools today. It mainly uses a high-power-density laser beam to irradiate the material to be cut, which quickly heats the material to its vaporization temperature and evaporates to form a hole. As the beam moves on the material, the hole continuously forms a very narrow kerf, completing the cutting of the material. During cutting, a fixture is needed to fix the bottom of the object to be cut. Once fixed, the workpiece cannot be moved. When cutting at different angles, the workpiece needs to be removed and re-fixed, which affects processing efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a fixed fixture for a high-precision laser cutting machine. It has a simple structure, is easy to install, and can be fixed at any position on the cutting machine. During cutting, it can fix the workpiece and rotate it at any time. It has good performance and a wide range of applications.

[0004] To solve the above-mentioned technical problems, this utility model provides a fixed fixture for a high-precision laser cutting machine, including a positioning table. A lifting cylinder is provided at the bottom of the positioning table. A first moving track is provided on the positioning table. A moving plate is provided on the first moving track. A second moving track is provided on the moving plate. A moving seat is provided on the second moving track. A rack is provided on the moving seat. Mounting shaft seats are provided on both sides of the rack. A rotating shaft is provided between the mounting shaft seats. A gear adapted to the rack is sleeved on the rotating shaft. A clamping cylinder is connected to one side of the rotating shaft. A clamping block is provided at the output end of the clamping cylinder.

[0005] Furthermore, the movable plate is provided with a mounting groove corresponding to the position of the second movable track, and both the movable plate and the bottom of the movable seat are provided with auxiliary moving blocks.

[0006] Furthermore, connecting plates are provided on the sides of both the movable base and the movable plate.

[0007] Furthermore, both the positioning platform and the moving plate are provided with positioning holes.

[0008] Furthermore, two clamping blocks are symmetrically arranged, and each clamping block includes two clamping arms.

[0009] The beneficial effects of this utility model are as follows: When using this device, the lifting cylinder is fixed on the bottom worktable. First, the workpiece is clamped using clamping blocks. Then, the clamping cylinder is activated. The lifting cylinder can drive the positioning table to move up and down to adjust the overall height of the device. The positioning table can be equipped with a drive device connected to a moving plate, and the moving plate can also be equipped with a drive device connected to a moving seat. The drive device can be a conventional device such as a motor or cylinder, which can drive the moving plate and the moving seat to move along the first and second moving tracks to adjust the horizontal position and rotation angle of the workpiece (the movement of the rack can drive the gear to rotate to achieve the rotation of the workpiece).

[0012] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0013] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0014] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0015] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0016] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0017] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.
