Description

Technical Field

[0001] This utility model relates to the field of mechanical production and processing technology, and in particular to a rotatable milling fixture. Background Technology

[0002] In existing milling processes, the fixtures used are mostly fixed and cannot be rotated to adapt to the milling angle of the tool. When using robotic milling, it is difficult to perform high-precision milling operations and achieve accurate milling of complex curved surfaces and surfaces with specific angles. Summary of the Invention

[0003] The purpose of this invention is to provide a rotatable milling fixture to address the actual situation encountered in the above-mentioned milling processes. This solves the problem that the existing milling fixture cannot be adjusted, resulting in a limited robot milling angle and an inability to complete complex curved surface milling. It also effectively improves the accuracy and efficiency of milling.

[0004] The technical solution adopted in this utility model is as follows: A rotatable milling fixture includes a base, a fixture, a rotating arm, a limiting rod, a transmission assembly, and a support assembly. The fixture comprises a fixture body and a fixture base plate integrally connected. The transmission assembly and the support assembly are fixedly mounted on both sides of one side and the middle of the other side of the base, respectively. The transmission assembly includes a servo motor, a motor mount, and a coupling. The servo motor is fixed to the motor mount, and the motor mount is fixed to the base. The support assembly includes a bearing, a rotating shaft, and a support seat. The rotating shaft is mounted on the support seat via the bearing. The support base is fixed on the base. One end of the coupling is connected to the spindle of the servo motor, and the other end is connected to the rotating shaft. One end of the rotating arm is fixed on the rotating shaft of the support assembly on one side of the base, and the other end is fixedly connected to the bottom side of the fixture base plate. One end of the limiting rod has a support surface, and the other end is fixed on the rotating shaft of the support assembly on the other side of the base. The limiting block also has a support surface corresponding to the support surface of the limiting rod, and has a slot. It is fixed to the bottom side of the fixture base plate. The limiting rod and the limiting block correspond to form a limiting and positioning structure.

Detailed Implementation

[0010] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described below are merely illustrative of this utility model. Key terms that need attention in these descriptions, including "swivel arm," "limiting rod," "limiting block," and "support surface," are simply customary names used for ease of description and to simplify the description; therefore, they should not be construed as limitations on this utility model.

[0011] like Figure 1-2As shown, the rotatable milling fixture of this utility model includes a base 5, a fixture, a rotating arm 12, a limiting rod 10, a transmission assembly, and a support assembly. The fixture includes a fixture body 1 and a fixture base plate 11 that are integrated together. The transmission assembly and the support assembly are fixedly installed on both sides of one side (rear side) and the middle of the other side (front side) of the base 5, respectively. The transmission assembly includes a servo motor 3, a motor base 6, and a coupling 7. The servo motor 3 is fixed on the motor base 6, and the motor base 6 is fixed on the base 5. The support assembly includes a bearing 8, a rotating shaft 9, and a support seat 13. The bearing 8 is a rolling bearing. The rotating shaft 9 is mounted on the support seat 13 through the bearing 8. The support seat 13 is fixed on the base 5. One end of the coupling 7 is connected to the spindle of the servo motor 3, and the other end is connected to the rotating shaft 9. In this embodiment, the rotating shaft 9 and the spindle of the servo motor 3 are concentric (i.e., the axes of the rotating shaft 9 and the spindle of the servo motor 3 form the same straight line). One end of the rotating arm 12 is fixed to the rotating shaft 9 of the rear support assembly of the base 5, and the other end is fixedly connected to the bottom of one side (rear side) of the fixture base plate 11. One end of the limiting rod 10 is provided with a support surface, and the other end is fixed to the rotating shaft 9 of the front support assembly of the base 5. The limiting block 14 is also provided with a support surface corresponding to the support surface of the limiting rod 10, and is provided with a slot. It is fixed to the bottom of the other side (front side) of the fixture base plate 11. The limiting rod 10 and the limiting block 14 correspond to form a limiting and positioning structure.

[0012] The working principle and usage of this rotatable milling fixture: First, the fixture body 1 is restored to the closed state of horizontal position by driving the servo motor 3 (e.g., Figure 1 (As shown), next, place the product body 2 onto the fixture body 1, ensuring all limit switches are in place and locked; finally, perform a vacuum operation to lock the product 2. At this time, the robot milling cutter 4 begins to complete the milling operation in the horizontal state of the fixture. Then, for parts where milling is difficult in the horizontal state of the fixture, the fixture needs to be rotated through an angle α, which is generally 60-100 degrees, to cooperate with the robot milling cutter 4 to complete the milling work of specific milling angles or complex curved surfaces to meet the milling requirements.

[0013] When the robotic milling cutter 4 cannot complete milling at a specific angle, it sends a signal to the controller to start the servo motors 3 on both sides of the base 5, which rotate and lift the fixture base plate 11. The fixture is then driven by the rotating arms 12 on both sides of the fixture base plate 11. After reaching the limit angle α and being in the open state, the limiting rod 10 of the limiting and positioning structure is driven by the servo motor 3 in the middle of the base 5. Finally, its supporting surface is in contact with the supporting surface of the limiting block 14 on the fixture base plate 11, and the limiting rod 10 is limited and positioned by the slot of the limiting block 14 to prevent the fixture from sinking and causing positional deviation. When the milling angle meets the requirements, the robotic milling cutter 4 receives a signal feedback and performs milling operation in the corresponding area to complete the entire milling production.

[0014] The above description is only a general embodiment of this utility model. For those skilled in the art, there are various other embodiments with modifications and variations, which will not be elaborated here. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model are included within the protection scope claimed by this utility model.
