DETAILED DESCRIPTION
[0018] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model are described in detail below with reference to the drawings.
[0019] As Figure 1and Figure 2 As shown, the CNC grinding machine provided in the embodiments of this application includes a mounting base 8 and a clamping mechanism disposed on the mounting base 8. It also includes a first grinding mechanism 1, a second grinding mechanism 2, a first lead screw module drive mechanism 3 disposed on the mounting base 8 for driving the first grinding mechanism 1 to move along the Y-axis, and a second lead screw module drive mechanism 4 for driving the second grinding mechanism 2 to move along the Y-axis. The first grinding mechanism 1 and the second grinding mechanism 2 have the same structure. Figure 3 As shown, the No. 1 grinding mechanism 1 includes a No. 1 seat 11 driven by a No. 1 lead screw module, a No. 1 linear guide rail 12 arranged on the No. 1 seat 11 along the Z-axis direction, a grinding component 13 slidably arranged on the No. 1 linear guide rail 12, a No. 1 worm gear connecting the grinding component 13 and the No. 1 seat 11 for driving the grinding component 13 to rise and fall, and a No. 1 handwheel 14 arranged on the No. 1 seat 11 for driving the No. 1 worm gear transmission.
[0020] In actual use, the shaft to be ground is clamped by a clamping mechanism. Then, the No. 1 lead screw drive module drives the No. 1 grinding mechanism 1 to move to a predetermined position, and the No. 2 lead screw drive module drives the No. 2 grinding mechanism 2 to move to a predetermined position. Grinding mechanism 1 and grinding mechanism 2 can be operated simultaneously, or one of them can operate at the same time. Grinding mechanism 1 and grinding mechanism 2 operate on the same principle. When grinding mechanism 1 is operating, the No. 1 handwheel 14 drives the No. 1 worm gear transmission, causing the No. 1 worm gear to lift and lower the grinding assembly 13 to the predetermined position for grinding.
[0021] In the above design, one or both of the No. 1 grinding mechanism and the No. 2 grinding mechanism can be used simultaneously, which can effectively improve work efficiency.
[0022] Specifically: such as Figure 3 As shown, the grinding assembly 13 includes a mounting frame 131 slidably connected to a linear guide rail 12, a rotating shaft 132 rotatably mounted on the mounting frame 131 along the Y-axis, a grinding wheel 133 coaxially fixed at one end of the rotating shaft 132, a driven pulley coaxially fixed at the other end of the rotating shaft 132, a motor 135 fixedly mounted on the mounting frame 131, a driving pulley coaxially fixed on the rotating shaft of the motor 135, and a synchronous belt 134 that is drively connected to the driving pulley and the driven pulley.
[0023] In actual use, the first handwheel 14 is rotated to drive the first worm gear transmission, which causes the mounting frame 131 to rise and fall. The first motor 135 drives the first drive pulley to rotate, and the first synchronous belt 134 drives the first driven pulley and the rotating shaft 132 to rotate, thereby realizing the rotation of the grinding wheel 133.
[0024] In the above design, the structural design and specific implementation of the grinding component 13 facilitate rapid and stable grinding.
[0025] Specifically: such as Figure 1 , Figure 2 and Figure 4 As shown, the clamping mechanism includes a left positioning component 51 disposed at one end of the side of the mounting base 8 and a right positioning component 52 disposed at the other end of the side of the mounting base 8. The left positioning component 51 includes a second motor 511 disposed on the mounting base 8, a second drive pulley coaxially fixed on the output shaft of the second motor 511, a left clamping seat 512 fixed on the mounting base 8, a left positioning column 513 rotatably disposed on the left clamping seat 512, a disc coaxially disposed on the left positioning column 513 and a second driven pulley, a screw 514 disposed on the disc, and a second synchronous belt 515 that is drivenly connected to the second drive pulley and the second driven pulley.
[0026] It should be noted that a clamp is provided on one side of the bottom cutter shaft to be ground, and the clamp can move synchronously after contacting the screw 514.
[0027] In actual use, the bottom tool shaft to be ground is clamped and positioned from both ends by the left positioning component 51 and the right positioning component 52, and then fed by rotation. The working principle of the left positioning component 51 is as follows: the positioning hole at the left end of the bottom tool shaft to be ground is positioned by the left positioning pin 513, and the second driving pulley is driven to rotate by the second motor 511. Under the transmission action of the second synchronous belt 515, the second driven pulley is driven to rotate synchronously. When rotating, the disc will drive the screw 514 to contact the included angle on the outer wall of the bottom tool shaft to be ground, and then drive the entire bottom tool shaft to be ground to rotate.
[0028] In the above design, the structure of the clamping mechanism facilitates the rotation of the bottom tool shaft to be ground.
[0029] Specifically: such as Figure 1 , Figure 2 and Figure 5 As shown, the right positioning assembly 52 includes a right clamping seat 521 slidably disposed on the mounting base 8 along the Y-axis direction, a right positioning column 522 rotatably disposed on the right clamping seat 521, a second worm gear connecting the mounting base 8 and the right clamping seat 521, and a second handwheel 523 disposed on the mounting base 8 for driving the second worm gear transmission.
[0030] In actual use, by rotating the second handwheel 523, the second worm gear transmission is driven, which causes the second worm gear to move the right clamping seat 521 in the Y-axis direction, thereby changing the distance between the left positioning component 51 and the right positioning component 52, which facilitates the feeding and unloading of the workpiece or the clamping of the workpiece.
[0031] In the above design, the structural design and specific implementation of the right positioning component 52 can effectively realize the feeding and unloading of the workpiece or the clamping of the workpiece.
[0032] Specifically: such as Figure 2 As shown, the mounting base 8 is also provided with a second linear guide rail 7 extending along the Y-axis direction, and both the first grinding mechanism 1 and the second grinding mechanism 2 are slidably connected to the second linear guide rail 7.
[0033] In the above design, the design of the second linear guide 7 facilitates smoother movement of both the first grinding mechanism 1 and the second grinding mechanism 2 in the Y-axis direction.
[0034] In further detail, it should be understood that the above description is only a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
