Description

Technical Field

[0001] This utility model relates to the field of CNC machine tools, and in particular to a high-precision horizontal slant guide rail CNC machine tool. Background Technology

[0002] CNC machine tools, short for numerical control machine tools, are automated machine tools equipped with a program control system. This control system can logically process programs with control codes or other symbolic instructions, decode them, represent them with coded numbers, and input them into the CNC device via an information carrier. After processing, the CNC device sends out various control signals to control the machine tool's movements, automatically machining parts according to the shape and dimensions required by the drawings.

[0003] Currently, CNC machine tools generally use guide rails to guide the movement of parts to be machined. Typically, two guide rails are placed flat on the machine tool, and the seat of the fixed part is slidably connected to the guide rails and driven by external force to approach the machining device. Then the machining device processes the part. However, it has been found that the seat may have poor stability when moving, resulting in the seat not being fully displaced, causing deviations in the machining of the part on the seat, affecting the accuracy of the part, and needs to be improved. Utility Model Content

[0004] To address the issue of unstable movement that may occur when parts are moving, this application provides a high-precision horizontal slant guide rail CNC machine tool.

[0005] The high-precision horizontal slant guide CNC machine tool provided in this application adopts the following technical solution:

[0006] A high-precision horizontal slant guide rail CNC machine tool includes a machine tool, a first mounting base disposed on the machine tool, and a drive assembly disposed on the first mounting base. A high rail and a low rail are respectively provided on the edges of both sides of the first mounting base, with the high rail located above the low rail. A slider is slidably connected to both the high rail and the low rail. A machining seat is fixed to the slider, and a machining turntable is rotatably connected to the machining seat. The machining turntable is used to fix parts, and a rotary motor for driving the machining turntable to rotate is provided on the machining seat. The drive assembly includes a threaded screw rotatably connected to the first mounting base and a servo motor disposed on the first mounting base. The machining seat is threadedly connected to the threaded screw, and the servo motor is used to drive the threaded screw to rotate.

[0007] By adopting the above technical solution, the common guide rails are laid flat on the top surface of the machine tool in pairs on the same horizontal plane, and then sliders are set on the guide rails, and finally the seat of the part is installed on the slider. This application sets a first mounting seat with different heights on both sides and installs a high rail and a low rail of the same specifications but different heights on both sides. Then, the slider and the machining seat are installed. When machining parts, multiple parts are installed on the machining turntable on the machining seat. Then, the drive component drives the parts to move closer to the machining device. Since the threaded screw has high precision and the servo motor can be preset according to the stroke of the slider, the high-precision horizontal inclined guide rail CNC machine tool of this application has high movement stability (the threaded connection of the machining seat of the threaded screw and the guidance of the high and low rails are more stable than the guidance of the double flat rails), so as to improve the problem of unstable movement when the parts move.

[0008] Preferably, the processing base has guide rails on both sides, the length direction of the guide rails is perpendicular to the length direction of the high rail, a movable base is slidably connected to the guide rails, the movable base is provided with a connecting base, the processing turntable and the motor are mounted on the connecting base; the movable base is provided with an adjustment component for driving the connecting base to move.

[0009] By adopting the above technical solution, a guide rail is set and the position of the moving seat on the guide rail is adjusted by the adjustment component to realize the adjustment of the width direction of the connecting seat on the moving seat, so that the machining turntable on the connecting seat can be set to correspond to the machining device, which facilitates the subsequent movement of the machining seat on the first mounting seat to the machining device.

[0010] Preferably, the adjustment assembly includes a first mounting block fixed to the movable base, a second mounting block fixed to the movable base, a threaded rod rotatably connected to the first mounting block and the second mounting block, and a drive motor disposed on the movable base, wherein the movable base is threadedly connected to the threaded rod.

[0011] By adopting the above technical solution, when the drive part moves in the width direction, the drive motor drives the threaded rod to rotate to drive the connecting seat to move, thereby driving the machining turntable on the connecting seat to move, so as to realize the adjustment of the machining turntable.

[0012] Preferably, the slider is provided with a sliding protrusion, and the high rail and the low rail are provided with sliding grooves for the sliding protrusion to slide.

[0013] By adopting the above technical solution, sliding protrusions and sliding grooves are set to improve the stability of the slider moving on the high rail and the low rail.

[0014] Preferably, the sliding protrusion has abutting inclined surfaces distributed on both sides, and the abutting inclined surfaces abut against the groove wall of the sliding groove.

[0015] By adopting the above technical solution, the sliding protrusion commonly used to improve movement stability is usually a cuboid. By increasing the contact surface (i.e. the abutting slope) of the sliding protrusion, the contact area between the sliding protrusion and the high rail and the low rail is increased, thereby improving the stability and accuracy of the slider movement.

[0016] Preferably, the machine tool is provided with a second mounting seat, the length direction of the second mounting seat is the same as the length direction of the first mounting seat, and mounting rails are provided on both sides of the second mounting seat.

[0017] By adopting the above technical solution, a second mounting base is set up and equipped with mounting rails to guide the movement of other components on the machine tool, which can serve as a second option for guiding the movement of parts and improve the practicality of the machine tool.

[0018] Preferably, the second mounting base has a waste trough at one end away from the end of the machine tool, and the machine tool has a discharge ramp that slopes downward toward the waste trough.

[0019] By adopting the above technical solution, a waste trough is set up to collect the waste generated during processing, preventing excessive accumulation of waste on the machine tool and affecting the guiding accuracy of the high rail, low rail and mounting rail. In addition, the downward slope of the unloading ramp facilitates the automatic falling of waste into the waste trough for collection.

[0020] The main technical effects of this utility model are reflected in the following aspects:

[0021] 1. This utility model improves the stability of parts transmission by setting high and low rails and rotating a threaded screw to drive the parts to move.

[0022] 2. This utility model increases the contact area between the sliding protrusion and the high and low rails by setting an abutting inclined surface, thereby improving the stability and accuracy of the slider movement;

[0023] 3. This utility model collects waste generated during processing by setting up a waste trough, preventing excessive accumulation of waste on the machine tool and affecting the guiding accuracy of the high rail, low rail and mounting rail. Attached Figure Description
