Abstract
Description
Technical Field
[0001] This utility model relates to the field of CNC grinding machine technology, specifically a grinding mechanism for a CNC grinding machine. Background Technology
[0002] CNC grinding machines are important equipment in the field of precision machining. They combine grinding technology and CNC technology, enabling them to complete the grinding of various complex-shaped parts with high precision and high efficiency.
[0003] CNC grinding machines consist of several major parts, including a headstock module, a tailstock module, a protective module, a cooling system, and a grinding mechanism. However, the existing grinding mechanism has a small travel range. Increasing the travel range of the grinding mechanism will increase the overall size of the equipment and occupy more floor space, making it difficult to meet usage requirements. Utility Model Content
[0004] The purpose of this utility model is to provide a grinding mechanism for a CNC grinding machine, which aims to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: the grinding mechanism of the CNC grinding machine includes a worktable, a base is provided on the worktable, the base has a mounting surface, the mounting surface of the base is inclined, a slide is provided on the mounting surface of the base, the slide is slidably connected to the base, a movable stage is provided on the upper surface of the slide, the movable stage is slidably connected to the slide, the slide and the base, as well as the slide and the movable stage, are respectively driven by ball screw pairs, a reduction motor is provided on the movable stage, a chuck is provided at the output end of the reduction motor, a drive module is connected to the chuck, a grinding wheel is provided at the output end of the drive module, and a grinding wheel cover is provided on the drive module.
[0006] Preferably, a support frame is provided at the lower end of the grinding wheel cover, a material box is provided inside the support frame, and a through groove is provided at one end of the material box.
[0007] Preferably, the slide table and the base, as well as the slide table and the movable table, are slidably connected by linear guide rails.
[0008] Preferably, the geared motor is positioned in the middle of the movable platform.
[0009] Preferably, the workbench is provided with a flow guide groove.
[0010] The beneficial effects of this utility model are:
[0011] The mounting surface of the base in this grinding mechanism is inclined, which increases the length of the slide table and thus the travel of the movable table on the slide table. This also increases the travel of the grinding wheel. With the increased travel of the grinding wheel, the parts of the slide table and movable table that protrude from the back of the worktable are significantly lower than when the mounting surface of the base is horizontal. This makes reasonable use of the space above the worktable, making the equipment more compact and reducing its floor space. Attached Figure Description

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0017] like Figure 1-3 As shown, a grinding mechanism of a CNC grinding machine includes a worktable 3, a base 4 on the worktable 3, the base 4 having a mounting surface, the mounting surface of the base 4 being inclined, a slide 5 on the mounting surface of the base 4, the slide 5 being slidably connected to the base 4, a movable table 6 on the upper surface of the slide 5, the movable table 6 being slidably connected to the slide 5, the slide 5 and the base 4 being connected to each other and the slide 5 and the movable table 6 being respectively driven by ball screw pairs 7, a reduction motor 8 on the movable table 6, a chuck 9 on the output end of the reduction motor 8, a drive module 10 connected to the chuck 9, a grinding wheel 11 on the output end of the drive module 10, and a grinding wheel cover 12 on the drive module 10.
[0018] The CNC grinding machine also includes a headstock module 1 and a tailstock module 2. The headstock module 1 and tailstock module 2 are installed on the worktable 3. The headstock module 1 and tailstock module 2 are used to clamp and fix the workpiece. At the same time, the headstock module 1 is used to control the workpiece to rotate. Since the headstock module 1 and tailstock module 2 are both existing technologies, their specific structures will not be described in detail.
[0019] Because the mounting surface of the base 4 is inclined, the length of the slide 5 can be increased, thereby increasing the stroke of the movable table 6 on the slide 5, which also increases the stroke of the grinding wheel 11. With the increased stroke of the grinding wheel 11, the parts of the slide 5 and the movable table 6 that protrude from the back of the worktable 3 will be significantly lower than when the mounting surface of the base 4 is horizontal. This makes reasonable use of the space above the worktable 3, making the equipment more compact and reducing the floor space occupied by the equipment.
[0020] Each set of ball screws is individually controlled by a servo motor. The movement of the servo motor can drive the slide 5 to move on the base 4 and drive the movable table 6 to move on the slide 5, thereby changing the spatial position of the grinding wheel 11 and making it convenient to move the grinding wheel 11 to a suitable position for grinding the outer surface of the workpiece.
[0021] The geared motor 8 can drive the drive module 10 to rotate via the chuck 9. The drive module 10 includes a motor and a gear reduction module. The drive module 10 can drive the grinding wheel 11 to rotate at high speed. When the outer surface of the workpiece is ground by the grinding wheel 11, the side of the grinding wheel 11 is perpendicular to the upper surface of the movable table 6. When it is necessary to chamfer the two ends of the workpiece, the geared motor 8 can drive the drive module 10 to rotate. By controlling the rotation of the drive module 10, the grinding wheel 11 is driven to rotate. After the grinding wheel 11 has completed its rotation, it is in an inclined state, which can chamfer the ends of the workpiece.
[0022] Furthermore, a support frame 13 is provided at the lower end of the grinding wheel cover 12, and a material box 14 is provided inside the support frame 13. A through groove 15 is provided at one end of the material box 14. The through groove 15 is connected to the pipe of an external suction device. When the grinding wheel 11 grinds the surface of the workpiece, the sand particles and iron filings produced can enter the material box 14. At the same time, the external suction device is activated and the sand particles and iron filings in the material box 14 are sucked out through the pipe and the material box 14 to avoid the sand particles and iron filings accumulating in the material box 14.
[0023] Furthermore, the slide table 5 is slidably connected to the base 4 and to the movable table 6 via linear guide rails 16.
[0024] Furthermore, the reduction motor 8 is positioned in the middle of the movable platform 6. When the reduction motor 8 moves to the highest position with the movable platform 6, the position of the reduction motor 8 still does not exceed the upper end of the slide table 5, thereby ensuring that the slide table 5 can provide continuous support for the reduction motor 8.
[0025] Furthermore, the worktable 3 is provided with a guide channel 17. When grinding the workpiece, cooling water is needed to cool the workpiece and the grinding wheel 11. The guide channel 17 can collect the cooling water and let it flow out from the worktable 3.
[0026] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
