Description

Technical Field

[0001] This utility model relates to the field of linear modules, and in particular to a high-load-bearing linear guide rail and a high-speed machine tool module. Background Technology

[0002] As a core transmission component in automated equipment and CNC machine tools, the linear motion module's load-bearing capacity and motion accuracy directly affect the performance of the machining system. Especially in the field of multi-axis high-speed machine tools, the moving module needs to achieve rapid and stable reciprocating motion under heavy load conditions, which places higher demands on the structural rigidity, assembly accuracy, and dynamic stability of the linear guide mechanism.

[0003] Traditional linear modules typically employ a guide rail slider and lead screw structure for drive. This type of structure is prone to slight vibrations due to assembly gaps during long-term high-load operation, leading to a decrease in positioning accuracy. Some improved solutions attempt to enhance rigidity by optimizing the slider's cross-sectional shape, but due to the limitations of the split design, its load-bearing capacity and resistance to eccentric loads remain bottlenecks. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, one of the objectives of this utility model is to provide a high load-bearing linear guide rail to improve motion stability under high load.

[0005] The second objective of this invention is to provide a high-speed machine tool module that includes the aforementioned high-load-bearing linear guide rail, so as to improve motion stability under high loads.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A high-load-bearing linear guide rail includes a linear guide rail and a synchronous slider that slides linearly along the linear guide rail under the drive of a drive mechanism.

[0008] The synchronous slider is connected to at least one guide slider of the linear guide rail;

[0009] The synchronous slider is also connected to the screw structure of the drive mechanism. The extension direction of the screw structure is in the same direction as the length direction of the linear guide rail, so that the synchronous slider is synchronously pulled by the screw structure and guided by the guide rail.

[0010] Furthermore, the linear guide rail also includes a first guide rail and a second guide rail, the first guide rail and the second guide rail being respectively placed on both sides of the synchronous slider, and the guide slider is provided on both the first guide rail and the second guide rail;

[0011] The bottom of the synchronization slider has a downward protruding gap that is embedded between the guide sliders, so that the gap is tightly connected to the guide sliders on both sides.

[0012] Furthermore, the space between the two parts is provided with a hole for fitting onto the screw nut, and the screw nut and the synchronous slider adopt a single-sided fixing structure.

[0013] Furthermore, the synchronizing slider has upwardly extending side wings on both sides.

[0014] Furthermore, the distal end of the screw structure is fixed to the housing of the module, and the proximal end is fixed to a reinforcing bracket located inside the housing.

[0015] A high-speed machine tool module includes a high-load-bearing linear guide rail as described above, wherein the high-load-bearing linear guide rails are located in pairs in the bottom movable base of the high-speed machine tool module to control the translation of the module.

[0016] Furthermore, it also includes a first rotation module for controlling the rotation of the cutter head along the vertical axis and a second rotation module for oscillating about the longitudinal axis.

[0017] The beneficial effects of this utility model are as follows:

[0018] The present invention provides a high load-bearing linear guide and a high-speed machine tool module, which minimizes the gap between the synchronous slider and the guide slider in the linear module, so that the three parts are tightly joined together. While ensuring the high-speed and precise movement of the equipment, the load-bearing performance is improved, so that it can be applied to the moving module at the bottom of a multi-axis high-speed machine tool.

[0024] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. The above description is for the purpose of simplifying the description of this utility model and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0025] Exemplary embodiments of this application will now be described with reference to the accompanying drawings. However, it should be understood that this application can be presented in many different ways and is not limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide further additional embodiments. Throughout the drawings, the same reference numerals denote the same or functionally identical elements.

[0026] Figure 1 and Figure 2 A high-load-bearing linear guide is shown, including a first guide rail 14, a second guide rail 15 constituting the linear guide mechanism, and a guide slider 17 disposed on the first guide rail 14 and the second guide rail 15, a motor 11 constituting the drive mechanism, and a screw structure disposed at the output end of the motor 11, consisting of a threaded crossbar 19 and a nut 18 sleeved on the threaded crossbar 19.

[0027] Reference Figure 3 The threaded crossbar 19 is arranged in the same direction as the length extension direction of the first guide rail 14 and the second guide rail 15. A synchronous slider 16, driven by a drive mechanism, is connected to the guide sliders 17 on the first guide rail 14 and the second guide rail 15. The bottom of the synchronous slider 16 has a downwardly protruding gap 16b. When the synchronous slider 16 is assembled with the guide slider 17, the gap 16b is embedded between the two sides of the synchronous slider 16, making the gap 16b and the synchronous slider 16 tightly connected, increasing the stability of the synchronous slider 16 during sliding. The nut 18 is inserted from one side into the through hole 16c in the gap 16b. This one-sided mounting and fixing structure is beneficial for assembly and can maintain motion stability while the synchronous slider 16 is clamped by the guide sliders 17 on both sides. The synchronous slider 16 is provided with upwardly protruding side wings 16a for connecting with the machine tool arm.

[0028] In a preferred embodiment, the hole 16c is designed to be semi-open, which further facilitates machining and assembly.

[0029] The near end of the threaded crossbar 19 is connected to the motor 11, and the far end is rotatably fixed to the housing 10a via a bearing 13b. To further improve the reliability of the near end, the near end is fixed in conjunction with the bearing 13a by an independent reinforcing bracket 12.

[0030] Combination Figure 4 This high-load-bearing linear module 10 is mainly used in multi-axis high-speed machine tool modules. A pair of high-load-bearing linear modules 10 are placed in a movable base structure to control the back-and-forth movement of the cutter head 60. The module also includes a first rotating module 40 for controlling the rotation of the cutter head 60 along the vertical axis and a second rotating module 50 for oscillating around the longitudinal axis. Due to the large load-bearing capacity at the bottom and the need to ensure high-speed and precise movement of the equipment, the gap between the synchronous slider 16 and the guide slider 17 is minimized to the greatest extent possible, so that the three parts are tightly joined together as one unit.
