Description

Technical Field

[0001] This utility model relates to the field of tooling fixture equipment technology, and in particular to a five-axis linkage fixture with multi-station rotary oil circuit distribution. Background Technology

[0002] With the development of the fixture industry, various types of fixtures have been widely used. However, these products still have some problems in practical use. For example, fixtures on the market usually adopt a single-station or fixed-rotation structure design, which makes it difficult to achieve independent rotation control of each station in multi-station machining scenarios. This leads to problems such as low machining efficiency, insufficient flexibility, and poor adaptability to different machining needs.

[0003] Existing patent document CN2019224735582 discloses a clamping device for lathe spindle machining. It achieves product clamping by setting a chuck in the CNC equipment and using a hydraulic cylinder as the drive source. However, the design of this fixture focuses on clamping under mechanical transmission and lacks support for independent rotation at each station, thus lacking flexibility when facing diverse machining tasks.

[0004] Therefore, it is necessary to design a five-axis linkage fixture with multi-station rotary oil circuit distribution to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a five-axis linkage fixture with multi-station rotary oil circuit distribution to overcome the above-mentioned shortcomings of the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A multi-station five-axis linkage fixture with rotary oil circuit distribution, comprising: Mounting bracket, tooling mounting bracket mounted on the mounting bracket via bearings, first driving device for driving the tooling mounting bracket to rotate, several sets of clamping assemblies disposed on the tooling mounting bracket, and rotary oil supply mechanism respectively connected to the clamping assemblies and driving the clamping assemblies to rotate. The rotary oil supply mechanism includes a rotary joint, an outer cylinder sleeved around the outer periphery of the rotary joint, and a mounting plate for mounting the outer cylinder.

[0007] Preferably, the clamping assembly includes a multi-jaw chuck, a pull rod assembly for driving the multi-jaw chuck to clamp or release, and a hydraulic cylinder connected to the pull rod assembly and driving the pull rod assembly to extend or retract. The hydraulic cylinder is connected to the rotary oil supply mechanism through a hydraulic pipeline.

[0008] Preferably, an annular oil cavity is formed between the inner hole of the rotary joint and the outer cylinder, and the annular oil cavity is connected to the clamping assembly through an oil passage.

[0009] Preferably, the rotary joint has an oil inlet on its side; the oil inlet is connected to an external hydraulic power source via a hose.

[0010] Preferably, the mounting plate is provided with a plurality of positioning pins, which are fixedly connected to the mounting plate by interference fit, and the top of the positioning pin is provided with a tapered guide surface.

[0011] Preferably, the clamping assembly is fixedly mounted on the rotary joint by bolts.

[0012] The beneficial effects of this utility model are: by setting a rotary oil supply mechanism, this technical solution distributes hydraulic oil to the hydraulic cylinder of each clamping component, realizing independent driving of multi-station clamping components; each clamping component can independently complete clamping or releasing operations according to processing requirements, significantly improving the flexibility of the fixture.

Detailed Implementation

[0014] Reference Figures 1 to 2 A multi-station five-axis linkage fixture with rotary oil circuit distribution, comprising: Mounting bracket 1, tooling mounting frame 2 mounted on the mounting bracket 1 via bearings, a first driving device for driving the tooling mounting frame 2 to rotate, several sets of clamping assemblies 3 disposed on the tooling mounting frame 2, and a rotary oil supply mechanism 4 respectively connected to the clamping assemblies 3 and driving the clamping assemblies 3 to rotate. The clamping assembly 3 includes a multi-jaw chuck 8, a pull rod assembly for driving the multi-jaw chuck 8 to clamp or release, and a hydraulic cylinder 7 connected to the pull rod assembly and driving the pull rod assembly to extend and retract. The hydraulic cylinder 7 is connected to the rotary oil supply mechanism 4 through a hydraulic pipeline. The piston rod of the hydraulic cylinder 7 is fixedly connected to the bottom of the pull rod assembly, and the top of the pull rod assembly is threadedly connected to the drive end of the multi-jaw chuck 8. Thus, the extension and retraction of the hydraulic cylinder 7 drives the pull rod assembly to move up and down, thereby driving the multi-jaw chuck 8 to perform clamping or releasing operations. The rotary oil supply mechanism 4 includes a rotary joint 5, an outer cylinder 6 sleeved around the outer periphery of the rotary joint 5, and a mounting plate for mounting the outer cylinder 6. An annular oil cavity is formed between the inner bore of the rotary joint 5 and the outer cylinder 6, and this annular oil cavity is connected to the hydraulic cylinder 7 via an oil passage. An oil inlet is provided on the side of the rotary joint 5; the oil inlet is connected to an external hydraulic source via a hose. A sealing ring is provided in the inner bore of the rotary joint 5, and the sealing ring is fixed to the inner wall of the rotary joint 5 by a pressure ring. The sealing ring is made of polytetrafluoroethylene (PTFE) and is used to prevent hydraulic oil leakage.

[0015] The mounting plate is provided with several locating pins, which are fixedly connected to the mounting plate by interference fit. The top of the locating pin is provided with a tapered guide surface to facilitate the installation and positioning of the rotating oil supply mechanism 4.

[0016] The clamping assembly 3 is fixedly mounted on the rotary joint 5 by bolts.

[0017] To further ensure the usability of the hydraulic cylinder, a pressure sensor is installed on the cylinder body of hydraulic cylinder 7. The pressure sensor is connected to an external controller via a signal line to monitor the working pressure of hydraulic cylinder 7 in real time. When the working pressure of hydraulic cylinder 7 exceeds the set range, the pressure sensor feeds the data back to the external controller. The controller adjusts the parameters of the hydraulic system based on the feedback data to ensure the stable operation of the clamp.

[0018] In actual use, the workpiece is placed between the arc-shaped clamping plates of the multi-jaw chuck 8. The hydraulic cylinder 7 receives hydraulic oil from the rotary oil supply mechanism 4 through the hydraulic pipeline. The piston rod of the hydraulic cylinder 7 pushes the pull rod assembly downward, which in turn drives the drive end of the multi-jaw chuck 8, causing the arc-shaped clamping plates to retract inward, thus completing the clamping operation of the workpiece. When it is necessary to release the workpiece, the piston rod of the hydraulic cylinder 7 moves upward, and the pull rod assembly drives the drive end of the multi-jaw chuck 8, causing the arc-shaped clamping plates to open outward, thereby releasing the workpiece.

[0019] The overall rotation of the tooling mounting frame 2 is driven by the first drive device. The servo motor drives the tooling mounting frame 2 to rotate around its central axis, thereby achieving overall angle adjustment of the workpiece. At the same time, the rotary joint 5 of the clamping assembly 3 rotates, and the clamping assembly 3 on it rotates synchronously, thereby achieving angle adjustment of the clamping assembly 3. In addition, the X / Y / Z drive module built into the CNC equipment is used to achieve five-axis drive.

[0020] The advantages of this utility model are that, by setting up a rotary oil supply mechanism, hydraulic oil is distributed to the hydraulic cylinder of each clamping component, realizing independent driving of multi-station clamping components; each clamping component can independently complete clamping or releasing operations according to processing requirements, which significantly improves the flexibility of the fixture.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
