Description

Technical Field

[0001] This invention relates to a horizontal machining center, belonging to the field of CNC machine tool technology. Background Technology

[0002] Current portal frame structures lack sufficient rigidity to support the spindle box when it is extended, resulting in structural instability. For example, in a drilling and milling device for a horizontal machining center disclosed in CN 116765834 A, the common support point for the second sliding member and the slide saddle is located on the front side of the slide block. This means that along the length of the second sliding member, there is only one support point, leading to insufficient rigidity. As the second sliding member extends, with increasing weight distribution, the slide saddle will inevitably undergo slight deformation due to the single support point, causing a slight sag at the front end of the second sliding member. The longer the second sliding member extends, the more pronounced this sag becomes, ultimately reducing machining accuracy. Therefore, in horizontal machining centers or five-axis machining centers with this structure, the forward and backward travel of the second sliding member is relatively short, and the overall rigidity is poor when cutting workpieces with the second sliding member extended, allowing only light cuts and not heavy cuts. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a horizontal machining center that can provide multi-point support to ensure that the spindle box will not tilt when extended, thereby improving support rigidity and machining accuracy. Furthermore, all moving parts are relatively light, while heavy components such as the support base do not need to be moved, which is more conducive to improving the machine's rapid movement response speed and improving machining efficiency.

[0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A horizontal machining center, comprising:

[0005] The base has a sagittal axis as the x-axis, a coronal axis as the z-axis, and a vertical axis as the y-axis;

[0006] A support base is fixed on the base, and a working square hole is formed in the middle of the support base along the z-axis direction;

[0007] Multiple first guide rails are arranged along the y-axis and fixed at intervals along the z-axis on the inner wall of the same side of the working square hole.

[0008] A slide block, which is slidably connected to multiple first guide rails;

[0009] The second guide rail includes guide rail A and guide rail B, both arranged along the z-axis direction. The first sliding end of the connector is slidably connected to the first guide rails. The guide rail A is slidably connected to the second sliding end of the connector along the z-axis direction, and the guide rail B is slidably connected to the slide block along the z-axis direction.

[0010] A spindle box, which is fixedly connected to guide rail A and guide rail B;

[0011] A first driving mechanism is mounted on the support base and its driving end drives the slide to move along the first guide rail.

[0012] A second drive mechanism is mounted on the slide and its drive end drives the spindle box to move along the guide rail A and the guide rail B.

[0013] A drive mechanism is installed inside the spindle box and its output shaft extends out of the spindle box. A cutting tool can be mounted on the output shaft of the drive mechanism and drive the cutting tool to rotate to process the workpiece.

[0014] The beneficial effects of the present invention are as follows: multiple first guide rails are arranged at intervals along the z-axis direction, the slide block is slidably connected to the multiple first guide rails, the first drive mechanism drives the slide block to move along the y-axis direction, and the spindle box slides along the z-axis direction through guide rail A and guide rail B. For the sliding direction of the spindle box, the multiple first rails provide multiple support points for the slide block, which improves the rigidity of the slide block and greatly improves the problem of sagging and reduced cutting accuracy caused by insufficient rigidity after the spindle box is extended, and also makes the spindle box have a longer stroke range.

[0015] The spindle box is slidably connected to the first track via guide rail A to prevent the spindle box from tilting to the side and improve the connection rigidity of the spindle box. It is also slidably connected to the slide block via guide rail B to improve stability and cutting accuracy.

[0016] Multiple first guide rails, guide rail A and guide rail B are connected to form multiple connection points, which improves the overall connection strength of the slide and the spindle box and prevents it from maintaining precise cutting accuracy when the center of gravity changes during movement.

[0017] The slide only supports the spindle box from below and does not enter between the spindle box and the first guide rail. This allows the spindle box to be closer to the first guide rail. The closer the spindle box is to the first guide rail, the better the rigidity of the first guide rail's support for the spindle box will be when subjected to force.

[0018] Based on the above technical solution, the present invention can be further improved as follows.

[0019] Furthermore, the first driving mechanism includes a first motor, a first screw, and a first nut. The first motor is fixed to the top of the support base. The support base has a through hole corresponding to the output shaft of the first motor, which communicates with the working square hole. The first screw is arranged along the y-axis direction, and its upper end is connected to the output shaft of the first motor through a first coupling. Its lower end is rotatably connected to the bottom of the support base through a first rotating connector. The first nut is fixed on the slide and threadedly connected to the first screw.

[0020] The beneficial effects of adopting the above-mentioned further solution are: the first nut is fixed on the slide, the first motor drives the first screw to rotate, the first screw is screwed to the first nut, which can drive the first nut to move along the first screw, thereby driving the slide to move along the first guide rail.

[0021] The two sliders are separated by a gap, which not only provides good support for the spindle box, but also allows the first screw to be closer to the spindle box for better driving effect.

[0022] Furthermore, the first rotating connector includes a first bearing and a first bearing housing, the first bearing housing is fixed to the bottom of the support base, the outer ring of the first bearing is fixed to the first bearing housing, and the first screw is fixed to the inner ring of the first bearing.

[0023] Furthermore, the second drive mechanism includes a second motor, a second screw, and a second nut. The second motor is fixed on the slide. The second screw is arranged along the z-axis and one end is connected to the output shaft of the second motor via a second coupling. The other end is rotatably connected to the slide via a second rotating connector. The second nut is fixed on the spindle box and threadedly connected to the second screw.

[0024] The beneficial effects of adopting the above-mentioned further solution are: the second nut is fixed on the spindle box, the second motor drives the second screw to rotate, the second screw is screwed to the second nut, which can drive the second nut to move along the second screw, thereby driving the spindle box to move along the guide rail A.

[0025] Furthermore, the second rotating connector includes a second bearing and a second bearing housing, the second bearing housing is fixed on the slide, the outer ring of the second bearing is fixed on the second bearing housing, and the second screw is fixed on the inner ring of the second bearing.

[0026] Furthermore, the connector includes two sliders, and there are two first guide rails. The first sliding ends of the two sliders are slidably connected to the two first guide rails, and the guide rail A is slidably connected to the second sliding ends of the two sliders.

[0027] The beneficial effects of adopting the above-mentioned further solution are: it facilitates the sliding connection of guide rail A to the two first guide rails; the two first guide rails, guide rail A and guide rail B are connected to form two connection points, which improves the overall connection strength of the slide and the spindle box.

[0028] The two first guide rails arranged along the z-axis have different orientations: the top surface of one first guide rail faces forward, and the top surface of the other first guide rail faces to the side. This can better take into account the forces in different directions and improve stability.

[0029] Furthermore, the driving mechanism is a drive motor, the spindle box has a mounting hole at its end along the z-axis direction, the drive motor is installed in the spindle box and its output shaft passes through the mounting hole, and the tool is installed on the output shaft of the drive motor.

[0030] Furthermore, it also includes a workpiece processing table, which is mounted on the base and corresponds to the output shaft of the drive motor.

[0031] Furthermore, the workpiece processing table includes two third guide rails, a CNC rotary table, a worktable, and a rotary motor. The two third guide rails are fixed on the base along the x-axis. The CNC rotary table is slidably connected to the two third guide rails. The worktable is rotatably connected to the CNC rotary table via a rotating shaft. The rotary motor is mounted on the CNC rotary table, and its output shaft is drively connected to the rotating shaft. It also includes a third drive mechanism, which is mounted on the base and used to drive the CNC rotary table to move on the third guide rails.

[0032] The beneficial effects of adopting the above-mentioned further solution are: when machining a workpiece, the workpiece is fixed on the worktable and moves along the x-axis with the CNC turntable, while the rotary motor drives the worktable to rotate, turning each side of the workpiece that needs to be machined to the output shaft of the drive motor holding the tool in sequence, thus completing the machining of the workpiece's periphery.

[0033] Furthermore, the third drive mechanism includes a third motor, a third screw, and a third nut. The third motor is mounted on the base. One end of the third screw is connected to the output shaft of the third motor via a third coupling, and the other end is rotatably connected to the base via a third rotating connector. The third nut is fixed on the CNC rotary table and is threadedly connected to the third screw. Attached Figure Description

The base 1 has a sagittal axis as the x-axis, a coronal axis as the z-axis, and a vertical axis as the y-axis. The support 2 is fixed on the base 1, and a working square hole 21 is opened in the middle of the support 2 along the z-axis direction. Multiple first guide rails 3 are arranged along the y-axis direction and fixed at intervals along the z-axis direction on the inner wall of the working square hole 21 on the same side.
