[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic internal polishing machine for precision parts, comprising a main frame, with a working positioning platform and a feeding platform respectively provided at the front and rear ends of the top of the main frame. The bottom of the working positioning platform is slidably connected to a slide rail fixedly provided on the top of the main frame via a slider. A first servo motor is fixedly provided at one end of the top of the feeding platform. A first moving screw is fixedly provided at the output end of the first servo motor via a coupling. A polishing component is provided on the first moving screw. The polishing component includes a slide rail seat, which is threadedly connected to the first moving screw. A lifting motor is rotatably provided on the front side of the slide rail seat via a rotary motor. An angle positioning seat is fixedly provided on the front side of the lifting motor. A second servo motor is fixedly mounted on the front side of the angle positioning seat via a mounting bracket. A universal chuck is fixedly provided at the bottom end of the second servo motor.

[0006] A dustproof shell is fixedly installed at the top edge of the main frame, and a PLC control panel is electrically connected to the right side of the main frame via wires.

[0007] A third servo motor is fixedly installed at the rear end position of the top middle of the main frame, and the front end of the third servo motor is threadedly connected to one of the sliders through a second moving lead screw.

[0008] Compared with the prior art, the beneficial effects of the present invention are:

[0009] This utility model features an angle positioning seat that, in conjunction with a rotating motor, can rotate to accommodate products with angled holes. The universal chuck achieves a perfect fit with the inner wall of the product. Driven and controlled by a PLC control panel, it enables automated polishing. The system can be programmed and defined according to the characteristics of different product models, and archived for secondary use, reducing labor costs and increasing production efficiency.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-3This utility model provides a technical solution: an automatic internal polishing machine for precision parts, including a main frame 1. A working positioning platform 2 and a feeding platform 3 are respectively provided at the front and rear ends of the top of the main frame 1. The bottom of the working positioning platform 2 is slidably connected to the slide rail fixedly provided at the top of the main frame 1 by a slider. A first servo motor 4 is fixedly provided at one end of the top of the feeding platform 3. A first moving screw 6 is fixedly provided at the output end of the first servo motor 4 by a coupling. A polishing component 5 is provided on the first moving screw 6. The polishing component 5 includes a slide rail seat 51. The slide rail seat 51 is threadedly connected to the first moving screw 6. A lifting motor 52 is rotatably provided on the front side of the slide rail seat 51 by a rotary motor. An angle positioning seat 53 is fixedly provided on the front side of the lifting motor 52. A second servo motor 55 is fixedly installed on the front side of the angle positioning seat 53 by a mounting bracket 54. A universal chuck 56 is fixedly provided at the bottom end of the second servo motor 55. The universal chuck 56 is located directly above the working positioning platform 2.

[0016] A dustproof shell 7 is fixedly installed at the top edge of the main frame 1, and a PLC control panel 8 is electrically connected to the right side of the main frame 1 via wires.

[0017] A third servo motor 10 is fixedly installed at the rear end position of the top middle of the main frame 1. The front end of the third servo motor 10 is threadedly connected to one of the sliders through the second moving lead screw 9.

[0018] Working principle: After the workpiece is placed on the work positioning platform 2, the PLC control panel 8 controls the first servo motor 4 to drive the first moving lead screw 6 to rotate, thereby moving the slide rail seat 51. At this time, the lifting motor 52 can drive the angle positioning seat 53 to rise and fall, while the rotary motor can rotate the lifting motor 52, thereby driving the universal chuck 56 to work.
