Description

Technical Field

[0001] This application relates to the field of clamping fixtures, and more specifically, to a rotary clamping fixture for machining parts. Background Technology

[0002] During the processing of parts, rotary clamping fixtures are often used. However, many rotary clamping fixtures are designed with certain specifications. Therefore, different specifications of rotary clamping fixtures need to be selected for parts of different sizes. This requires disassembling and replacing the parts of the rotary clamping fixture with suitable parts. Disassembly and reassembly waste time, mainly because the rotary clamping fixtures of certain specifications have low compatibility. Utility Model Content

[0003] To overcome the above shortcomings, this application provides a rotary clamping fixture for parts processing, which aims to improve the problem that the parts that need to be disassembled and replaced with suitable parts are wasted time during disassembly and reinstallation. The main issue is that rotary clamping fixtures of a certain specification have low compatibility.

[0004] This application provides a rotary clamping fixture for machining parts, including a rotating frame and a clamping assembly. The clamping assembly includes a rotating ring, a sliding bar, a transverse bidirectional slide rail, a longitudinal bidirectional slide rail, and clamping rods. The rotating end of the rotating ring is rotatably connected to the rotating frame. Multiple sliding bars and clamping rods are spaced apart. The sliding bar is slidably connected to the upper part of the rotating frame and is drively connected to the rotating end of the rotating ring. The clamping rod is slidably connected to one side of the sliding bar and rotatably connected to the sliding bar. The bottoms of two clamping rods are rotatably connected to the two sliding ends of the transverse bidirectional slide rail, and the bottoms of the other two clamping rods are rotatably connected to the two sliding ends of the longitudinal bidirectional slide rail. Both the transverse bidirectional slide rail and the longitudinal bidirectional slide rail are located on one side of the rotating frame.

[0005] In one specific implementation, the rotating frame includes a base frame, an upright frame, a ring frame, a support plate, and a first motor. The bottom of the upright frame is rotatably connected to the base frame, the ring frame is fixedly connected to one side of the upper part of the upright frame, the support plate is fixedly connected to the upper part of the upright frame, the first motor is fixedly connected to the base frame, and the output end of the first motor is drively connected to the upright frame.

[0006] In one specific implementation, the first motor output end is provided with a first gear, and the upright is provided with a first gear ring, the first gear being meshed with the first gear ring.

[0007] In one specific implementation, the rotating ring includes a second motor and a circle, the circle being rotatably connected to the ring frame, the second motor being fixedly connected to the upright frame, and the output end of the second motor being drively connected to the circle.

[0008] In one specific implementation, the output end of the second motor is provided with a second gear, and the circle is provided with a second gear ring, the second gear being meshed with the second gear ring.

[0009] In one specific implementation, the circle is provided with a spiral strip, the sliding strip is provided with teeth, and the teeth are connected to the spiral strip in a driving manner.

[0010] In one specific implementation, the clamping rod has a groove, and the sliding bar has a round block inserted inside the groove.

[0011] In one specific implementation, both the transverse bidirectional slide rail and the longitudinal bidirectional slide rail include a third motor, a bidirectional threaded rod, and a slider. The sliders are symmetrically arranged. The third motor is fixedly connected to the upright. The output end of the third motor is drivenly connected to the bidirectional threaded rod. The bidirectional threaded rod is rotatably connected to the upright. The slider is slidably connected to the upright. The slider is threadedly connected to the bidirectional threaded rod. The slider is rotatably connected to the bottom of the clamping rod.

[0012] Beneficial Effects: This application provides a rotary clamping fixture for parts processing. During use, the positions of multiple sliding bars are adjusted according to the different sizes of the parts. The rotating end of the rotating ring drives the movement of the sliding bars. At this time, the multiple sliding bars move towards the upper center of the rotating frame, or towards a direction away from the upper center of the rotating frame. While adjusting the movement of the sliding bars, the sliding ends of the transverse and longitudinal bidirectional slide rails move synchronously with the movement of the sliding bars. After adjusting the positions of the sliding bars and clamping rods, the parts can be placed between the multiple clamping rods, also placed on the upper part of the rotating frame. The sliding ends of the transverse and longitudinal bidirectional slide rails drive the movement of the clamping rods to clamp the parts. Furthermore, the rotating end of the rotating frame drives the rotating ring, sliding bars, and clamping rods to rotate synchronously. Throughout the entire process, the spacing between the clamping rods can be adjusted according to the different specifications of the parts, thus adapting to the clamping and processing of different parts and improving the adaptability of the rotary clamping fixture.

[0023] The working principle of this rotary clamping fixture for machining parts is as follows: The positions of multiple sliding bars 220 are adjusted according to the different volumes of the parts. The rotating end of the rotating ring 210 drives the movement of the sliding bars 220. At this time, the multiple sliding bars 220 move towards the upper center of the rotating frame 100, or move away from the upper center of the rotating frame 100. While adjusting the movement of the sliding bars 220, the sliding ends of the transverse bidirectional slide rail 230 and the longitudinal bidirectional slide rail 240 move synchronously following the movement of the sliding bars 220. The positions of the sliding bars 220 and the clamping rod 250 are then adjusted. Then, the parts can be placed between multiple clamping rods 250, which are also placed on the upper part of the rotating frame 100. The sliding ends of the transverse bidirectional slide rail 230 and the longitudinal bidirectional slide rail 240 drive the movement of the clamping rods 250 to clamp the parts. The rotating end of the rotating frame 100 can drive the rotating ring 210, the sliding bar 220 and the clamping rods 250 to rotate synchronously. During the entire use, the spacing between the clamping rods 250 can be adjusted according to the different specifications of the parts, so as to adapt to the clamping and processing of different parts, thereby improving the adaptability of the rotary clamping fixture.
