[0021] Example

[0022] See also Figures 1 to 4 In the embodiment of the utility model, a feeding device for a CNC lathe that is easy to adjust includes a mounting frame 1, and a front and rear slide rail 2 is arranged on the inner wall below the mounting frame 1. A rack 3 is slidably arranged on the slide rail 2. A gear 4 is also rotatably arranged inside the mounting frame 1, and the gear 4 and the rack 3 are meshed with each other. At this time, rotating the gear 4 can drive the rack 3 to move. A clamping plate 6 is also arranged on the top of the rack 3 through a mounting block. Under the action of the clamping plate 6, when the gear 4 rotates, the rack 3 is used to drive the left and right clamping plates 6 to move closer or farther away, so that the clamping plate 6 can clamp and fix the workpiece to be processed, thereby facilitating the subsequent feeding of the workpiece. In addition, it can also better meet the clamping and fixation of workpieces of different sizes, thereby improving the applicability of the device to a certain extent. A first electric push rod 7 is also provided on the left outer wall of the mounting frame 1 through the mounting plate 8. The end of the telescopic arm of the first electric push rod 7 is connected to the rack 3 through the connecting plate 5. The first electric push rod 7 is used to drive the front rack 3 to move, and then the front rack 3 drives the gear 4 to rotate, and then the right clamping plate 6 is driven to move through the rear rack 3, so that the clamping plate 6 can clamp and fix the workpiece, thereby ensuring the fixing quality of the device for the workpiece. A limiting block is also provided at the bottom of the clamping plate 6, and a limiting groove used in conjunction with the limiting block is provided on the mounting frame 1. Under the action of the limiting block and the limiting groove, the sliding quality of the clamping plate 6 is guaranteed, so that the clamping plate 6 can better clamp and fix the workpiece. 6. A through hole for the first electric push rod 7 to pass through is provided on the side wall of the mounting frame 1.

[0023] A second electric push rod 9 is also provided on the top of the mounting frame 1, and a push plate 10 is provided at the end of the telescopic arm on the top of the second electric push rod 9. Under the action of the push plate 10, the workpiece clamped by the clamping plate 6 can be pushed, so that the device can better feed the workpiece.

[0024] A plurality of telescopic rods 11 are evenly arranged at the bottom of the mounting frame 1, a base 12 is arranged at the end of the telescopic arm at the bottom of the telescopic rod 11, and two front and rear sliding rods 13 are arranged inside the base 12. Two left and right first hinge blocks 14 are slidably arranged on the sliding rod 13, a connecting rod 15 is hingedly arranged on the first hinge block 14, and a second hinge block 16 is hingedly arranged at the top end of the connecting rod 15, and the second hinge block 16 is slidably connected to the mounting frame 1. When it is necessary to adjust the height of the device, the first hinge block 14 is moved through the inside of the box, and the height of the mounting frame 1 is adjusted by using the connecting rod 15 and the second hinge block 16, so as to adjust the height of the device, so that the device can better meet the actual use needs, thereby improving the applicability of the device and ensuring the use efficiency and quality of the device.

[0025] A bidirectional screw 17 is also rotatably arranged inside the base 12, and a fixing plate 18 is also arranged between the front and rear first hinge blocks 14, and the bidirectional screw 17 penetrates the fixing plate 18 and is threadedly connected to the fixing plate 18. At this time, rotating the bidirectional screw 17 can drive the left and right first hinge blocks 14 to move closer or farther away, and then the height of the mounting frame 1 is adjusted by using the connecting rod 15. A motor 1701 is also arranged on the right outer wall of the base 12, and the power output shaft of the motor 1701 is connected to the bidirectional screw 17 through a coupling. The motor 1701 can be used to drive the left and right first hinge blocks 14 to move closer through the bidirectional screw 17, thereby adjusting the height of the mounting frame 1 through the connecting rod 15 and the second hinge block 16, so that the device can better meet actual usage requirements.

[0026] During actual use, the first electric push rod 7 is used to drive the front rack 4 to move, and then drive the gear 4 to rotate. Since the gear 4 is meshed with the front and rear racks 3, the rotation of the gear 4 will drive the front and rear racks 3 to move synchronously, thereby driving the left and right clamping plates 6 to move toward or away from each other, thereby clamping or releasing the workpiece. When the workpiece is firmly clamped by the clamping plate 6, the second electric push rod 9 starts to work, and the telescopic arm at its top pushes the push plate 10 to move forward, thereby pushing the workpiece on the clamping plate 6 to move forward, thereby feeding the workpiece. When the height of the device needs to be adjusted to adapt to different working environments or workpiece requirements, the start motor 1701 drives the bidirectional screw 17 to rotate. Since the bidirectional screw 17 is threadedly connected to the first hinge block 14 on the fixed plate 18, the rotation of the screw will drive the left and right first hinge blocks 14 to move toward or away from each other. The movement of the first hinge block 14 is converted into a lifting movement of the mounting frame 1 through the hinge action of the connecting rod 15 and the second hinge block 16, thereby realizing the overall height adjustment of the device.
