Description

Technical Field

[0001] This utility model belongs to the field of milling machine positioning fixture technology, specifically relating to a multi-angle milling machine rapid positioning fixture. Background Technology

[0002] A milling machine quick positioning fixture is a tooling fixture specifically designed for milling machine processing. Its core function is to enable the quick clamping and precise positioning of the workpiece on the milling machine, and to maintain the workpiece position efficiently and stably to meet the accuracy and efficiency requirements of milling processing.

[0003] However, the quick positioning fixture for milling machines has certain limitations in actual use. When the workpiece needs to be adjusted at multiple angles, the ease of operation is not good. Although it can achieve quick clamping and accurate positioning, angle adjustment often requires manual operation of the indexing plate or multiple calibrations. Especially when frequently switching between different angles, the slow response of the locking mechanism and the cumbersome fine-tuning steps can lead to an extension of the processing gap and affect the efficiency of mass production.

[0004] To address the aforementioned issues, this application proposes a multi-angle milling machine rapid positioning fixture. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides a multi-angle milling machine quick positioning fixture, which features convenient multi-angle adjustment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-angle milling machine rapid positioning fixture, comprising a base plate, a collar fixedly connected to the upper surface of the base plate, a rotating ring rotatably connected inside the collar, a controller and a first brake motor respectively disposed below the base plate, the power output end of the first brake motor passing through the base plate and the collar in sequence and fixedly connected to the bottom surface of the rotating ring, two telescopic frames and two first electric push rods respectively disposed on the outer surface of the rotating ring, a second electric push rod disposed above each telescopic frame, a rotating bearing fixedly connected to the outer surface of each second electric push rod, a fixed frame fixedly connected to the outer surface of the outer ring of each rotating bearing, the bottom surface of each fixed frame fixedly connected to the telescopic end of the telescopic frame, a limit ring fixedly connected to the telescopic end of each second electric push rod, a second brake motor disposed on the side of the two telescopic frames that are far apart from each other, and the power output ends of the two second brake motors fixedly connected to the ends of the two second electric push rods that are far apart from each other.

[0027] Specifically, a mounting plate 5 is fixedly connected to the right side of the controller 3. The upper surface of the mounting plate 5 is fixedly connected to the bottom surface of the base plate 1. In this embodiment, the controller 3 can be fixed by the mounting plate 5. At the same time, the controller 3 is a digital computing and operating electronic system designed for industrial environments. It stores instructions through a programmable memory and is used to perform logical operations, sequential control, timing, counting and arithmetic operations, etc. It controls various types of machinery or production processes through digital or analog input and output to realize industrial automation control.

[0028] Specifically, two support plates 9 are fixedly connected to the outer surface of the rotating ring 7. The upper surface of each support plate 9 is fixedly connected to the bottom surface of the telescopic frame 8 and the first electric push rod 12. In this embodiment, the support plates 9 can fix the telescopic frame 8 and the first electric push rod 12 to the rotating ring 7, so that the telescopic frame 8 and the first electric push rod 12 can be used stably.

[0029] Specifically, each of the first electric push rods 12 has a connecting plate 13 fixedly connected to its telescopic end. The two connecting plates 13 are fixedly connected to the sides of the telescopic ends of the two telescopic frames 8 that are far apart from each other. In this embodiment, the connecting plates 13 can fix the first electric push rods 12 to the telescopic ends of the telescopic frames 8, so that the first electric push rods 12 can drive the telescopic frames 8 to telescopic.

[0030] Specifically, a connecting seat 11 is fixedly connected to the right side of the first brake motor 10. The upper surface of the connecting seat 11 is fixedly connected to the bottom surface of the base plate 1. In this embodiment, the first brake motor 10 can be fixed by the connecting seat 11, and the first brake motor 10 can be made firm.

[0031] Specifically, a connecting frame 16 is fixedly connected to the upper surface of each second brake motor 15, and the inner top wall of each connecting frame 16 is fixedly connected to the upper surface of the fixed frame 17. In this embodiment, the second brake motor 15 can be fixed to the fixed frame 17 through the connecting frame 16, so that the second brake motor 15 can rotate stably.

[0032] Specifically, protective rings 20 are fixedly connected to the sides of the two limiting rings 19 that are close to each other. Each protective ring 20 is made of rubber. In this embodiment, the soft material of the protective rings 20 can protect the surface of the limiting rings 19 and the workpiece.

[0033] The working principle and usage process of this utility model are as follows: First, check the status of each component of the device to ensure that the braking functions of the first brake motor 10 and the second brake motor 15 are normal, the rotating ring 7 rotates smoothly within the collar 2, the telescopic frame 8, the first electric push rod 12, and the second electric push rod 14 extend and retract flexibly, and the protective ring 20 is undamaged. Then, reset each component to its initial position using the controller 3, so that the two limit rings 19 are in their maximum open state, and the angle adjustment mechanism returns to zero. Next, place the workpiece to be processed between the two limit rings 19. Operate the controller 3 to start the first electric push rod 12 and the second electric push rod 14. The first electric push rod 12 drives the telescopic frame 8 to retract via the connecting plate 13, simultaneously adjusting the height. The second electric push rod 14 extends and retracts simultaneously, bringing the two limit rings 19 closer together and adjusting them to a height suitable for the workpiece, until the rubber protective ring 20 tightly adheres to the workpiece surface, completing the workpiece clamping and fixing. To prevent displacement during processing, when the horizontal angle needs to be adjusted, the target angle is input through the controller 3. The first brake motor 10 drives the rotating ring 7 to rotate around the vertical axis within the collar 2. After reaching the preset angle, the braking device of the first brake motor 10 immediately locks the rotating shaft to ensure angle stability. When adjusting the vertical angle, the controller 3 controls the second brake motor 15 to start, driving the second electric push rod 14 to rotate around the horizontal axis around the rotating bearing 18. The fixed frame 17 is connected to the telescopic frame 8 to provide rotational support. After reaching the target angle, the second brake motor 15 locks, achieving vertical positioning. During processing, if the angle needs to be switched, the above angle adjustment steps can be repeated directly through the controller 3 without disassembling the workpiece. After processing, the controller 3 controls each electric push rod to reset, the limit ring 19 opens, the workpiece is removed, and finally, the iron filings on the surface of the device are cleaned to complete the operation, further realizing the convenience and precision of multi-angle processing.
