[0019] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.
[0020] Embodiment 1
[0021] Reference Figures 1 to 3 As shown, the first embodiment provides a movable crossbeam with a composite guide rail structure (hereinafter referred to as the movable crossbeam), which is used to carry the slide of the processing machine tool and cooperate to make corresponding movements.
[0022] The movable crossbeam of this embodiment includes a movable crossbeam body 1, and has a first surface 11 and a second surface 12 which are opposite to each other along its X-axis direction. The first surface 11 is provided with a first hard rail 2 and a steel-insulated guide rail 3 extending along the Y-axis direction of the movable crossbeam body 1, and the second surface 12 is provided with a second hard rail 5 and a slider mounting groove 6 extending along the Z-axis direction of the movable crossbeam body 1. The slider mounting groove 6 is used to assemble the linear rail slider of the processing machine tool. The movable crossbeam body 1 is provided with a transverse linear rail 4 extending along the Y-axis direction of the movable crossbeam body 1 at its upper end 13 in the Z-axis direction.
[0023] In this embodiment, the specific moving beam body 1 is a rectangular structure, and the X-axis direction is defined as the thickness direction of the moving beam body 1, the Y-axis direction is defined as the length direction of the moving beam body 1, and the Z-axis direction is defined as the width direction of the moving beam body 1. In normal operation, the moving beam body 1 is assembled on the track of the column of the processing machine tool in a sliding connection manner, and the width direction of the moving beam body 1 is parallel to the track direction of the column. At the same time, the slide seat of the processing machine tool is slidably connected to the moving beam body 1.
[0024] More specifically, there are two first hard rails 2, two second hard rails 5 and two slider mounting grooves 6, and one steel-embedded guide rail 3 is provided. The two first hard rails 2 are spaced apart, the steel-embedded guide rail 3 is located between the two first hard rails 2, and the steel-embedded guide rail 3 is adjacent to one of the first hard rails 2.
[0025] Through the combined cooperation of the horizontal linear guide 4, the first hard guide 2, and the steel-inlaid guide rail 3, a composite guide rail structure combining hard and linear guide surfaces is formed on the side where the first surface 11 is located, thereby ensuring that the carriage of the machining tool can move along the Y-axis direction of the moving beam body 1, and when the carriage of the machining tool is under machining, the moving beam body 1 has sufficient rigidity to resist the load brought during machining. Moreover, the horizontal linear guide 4 can ensure that the moving speed of the carriage on the moving beam body 1 is fast enough and has good positioning accuracy and machining accuracy.
[0026] In addition, two second hard guides 5 and the slider mounting grooves 6 are respectively located on both sides of the moving beam body 1 in the Y-axis direction to ensure that the supporting forces received by the moving beam body 1 during ascending and descending in the Z-axis direction are symmetrical and the motion posture is stable.
[0027] Corresponding nut seats 7 are respectively arranged between the second hard guide 5 and the slider mounting groove 6 on each side. Both of the two nut seats 7 are used to connect the lead screws on the columns of the machining tool to drive the moving beam body 1 to ascend and descend along the Z-axis direction on the tracks of the columns.
[0028] After the linear guide slider of the machining tool is assembled in the slider mounting groove 6, a sliding connection with a smaller contact surface is formed through the linear guide track of the column of the machining tool in cooperation with the linear guide slider, and a sliding connection with a larger contact surface is formed through the cooperation of the second hard guide 5 and the hard guide track of the column of the machining tool, so as to form a composite guide rail structure combining hard and linear guide surfaces on the side where the second surface 12 is located, and have sufficient rigidity to resist the load brought during machining when performing machining along the Z-axis direction on the tracks of the column.
[0029] By arranging the first hard guide 2 and the steel-inlaid guide rail 3 on the first surface 11 of the moving beam body 1 and arranging the horizontal linear guide 4 on the upper end 13 of the moving beam body 1, it is ensured that the carriage of the machining tool can move along the Y-axis direction on the moving beam body 1. At the same time, by arranging the second hard guide 5 on the second surface 12 of the moving beam body 1 and the slider mounting groove 6 for assembling the linear guide slider of the machining tool, it is ensured that the moving beam body 1 can move along the Z-axis direction on the tracks of the column of the machining tool. Furthermore, the moving beam of this embodiment has a composite guide rail structure combining hard rails and linear rails, which can ensure sufficient rigidity, while ensuring a high moving speed, and the machining tool has good machining accuracy, stability, and accuracy of the machining position, and can also accept workpieces to be machined with complex shapes, and is convenient for maintenance and has low maintenance costs.
[0030] Of course, in other embodiments, the set numbers of the first hard guide 2, the steel-inlaid guide rail 3, the horizontal linear guide 4, the second hard guide 5, and the slider mounting groove 6 are not limited to this, and the specific set numbers are determined by the dimensions and structures of the moving beam body 1 and the machining tool.
[0031] In addition, transverse linear guides 4 can also be provided at both the upper end 13 and the lower end of the moving crossbeam body 1, or a transverse linear guide 4 can be provided solely at its lower end, and thus the cooperation with the slide can also be achieved for movement.
[0032] Further preferably, the guide rail area of the inserted steel guide rail 3 is smaller than that of the first hard guide rail 2, so as to ensure that the inserted steel guide rail 3 has both a linear guide rail surface and a hard guide rail surface, and further ensure the rigidity, moving speed and moving accuracy of the moving crossbeam body 1.
[0033] Embodiment 2
[0034] Embodiment 2 provides a processing machine tool, which at least includes the moving crossbeam with a composite guide rail structure in Embodiment 1.
