[0002] A CNC machining support fixture is a device used to fix workpieces and plays a crucial role in the CNC machining process. It ensures the positional accuracy and stability of the workpiece during machining, thereby improving machining quality and efficiency. In existing CNC machining processes, when different workpieces need to be clamped, the previous fixture needs to be disassembled and then a new fixture needs to be installed, which is a relatively complicated operation and affects machining efficiency. Therefore, we propose a CNC machining support fixture. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Example 1:

[0025] A preferred embodiment of the CNC machining support fixture provided by this utility model is, for example... Figures 1 to 6 As shown: A CNC machining support fixture includes a base 1 and a combined fixture. The combined fixture includes a first fixture 4 and a second fixture 5. A support plate 1 2 and a support plate 2 3 are fixedly installed on the top of the base 1 near both sides. The bottom of the first fixture 4 and the top of the second fixture 5 are in contact with each other. A hydraulic cylinder 8 is fixedly installed on one side of the support plate 1 2. A mounting plate 9 is fixedly installed on one end of the piston rod of the hydraulic cylinder 8. A connecting shaft 11 is fixedly installed on the inner side of the mounting plate 9. A fixed frame 10 is rotatably connected to one end of the connecting shaft 11 through a bearing seat. A motor 12 is fixedly installed on one side of the support plate 2 3. A rotating shaft 13 is fixedly installed on the output end of the motor 12. The rotating shaft 13 movably passes through the support plate 2 3 and is rotatably connected to the support plate 2 3 through a bearing. A fixed frame 2 14 is fixedly installed on one end of the rotating shaft 13. The fixed frame 10 and the fixed frame 2 14 are respectively engaged on both sides of the combined fixture. A limit mechanism 7 is provided on both the support plate 1 2 and the support plate 2 3.

[0026] The limiting mechanism 7 includes two U-shaped limiting frames 601. The U-shaped limiting frames 601 movably pass through the support plate 2, and the outer wall of the fixed frame 10 is provided with a limiting groove 602. The U-shaped limiting frames 601 are inserted into the limiting groove 602. A limiting rod 603 is fixedly installed on the outer side of the support plate 2. A rod hole 604 is provided on the U-shaped limiting frame 601. The limiting rod 603 movably passes through the rod hole 604. A baffle 606 is fixedly installed at one end of the limiting rod 603. A spring 605 is fixedly connected between the baffle 606 and the U-shaped limiting frame 601. The spring 605 surrounds the outer wall of the limiting rod 603.

[0027] Specifically, in the above technical solution, when using the CNC machining support fixture, the first fixture 4 and the second fixture 5 are combined and installed. When it is necessary to clamp different workpieces and change fixtures, the handle 607 can be pulled outward, causing the handle 607 to move the U-shaped limiting frame 601 outward, compressing the spring 605 of the U-shaped limiting frame 601, causing the U-shaped limiting frame 601 to disengage from the limiting groove 602, so that the U-shaped limiting frame 601 no longer limits the fixed frame 10 and the fixed frame 2 14. At this time, the motor 12 can be started, causing the motor 12 to drive the fixed frame 2 14 to rotate 180° through the rotating shaft 13, so that the second fixture 5 is in the machining position, and then the U-shaped limiting frame 601 can be released. 1. At this time, the U-shaped limiting frame 601 will be inserted into the limiting groove 602 again under the reset force of the spring 605, limiting and fixing the first fixed frame 10 and the second fixed frame 14, thereby completing the conversion between the first fixture 4 and the second fixture 5. Through the above structure, two fixtures to be used can be installed at the same time. When different workpieces need to be clamped and processed, the motor 12 can be started directly to directly switch between the two fixtures, which greatly improves the processing efficiency and solves the problem that in the existing CNC processing process, when different workpieces need to be clamped, the previous fixture needs to be disassembled and then a new fixture needs to be installed, which is more complicated and affects the processing efficiency.

[0028] Furthermore, a handle 607 is fixedly installed between the two U-shaped limiting frames 601, and the U-shaped limiting frames 601 are adapted to the limiting grooves 602;

[0029] The design incorporates a handle 607, which allows personnel to directly pull the two U-shaped limit frames 601, thus facilitating operation.

[0030] Furthermore, both the inner walls of the first fixed frame 10 and the second fixed frame 14 are fixedly installed with a locking block 15, and the outer walls of the first clamp 4 and the second clamp 5 are provided with a slot 16, in which the locking block 15 is engaged.

[0031] By setting a locking block 15, the locking block 15 is inserted into the locking slot 16 to limit and fix the first clamp 4 and the second clamp 5, thereby further improving the stability of the connection between the first clamp 4 and the second clamp 5.

[0032] Furthermore, the number of locking blocks 15 on the first fixed frame 10 and the second fixed frame 14 is four, and the number of locking slots 16 on the first clamp 4 and the second clamp 5 is four, and the locking blocks 15 are compatible with the locking slots 16.

[0033] Example 2:

[0034] Based on Embodiment 1, a preferred embodiment of the CNC machining support fixture provided by this utility model is, for example... Figures 1 to 6As shown: Both support plate 2 and support plate 3 are provided with a limiting mechanism 7 on their outer sides. The limiting mechanism 7 includes a limiting block 701, which is slidably connected to the outer wall of support plate 2. A magnetic plate 704 is magnetically connected to the top of the limiting block 701, and the magnetic plate 704 is fixedly installed on the outer side of support plate 3.

[0035] Specifically, in the above technical solution, after the U-shaped limiting frame 601 is disengaged from the limiting groove 602, the limiting block 701 can be directly pushed downwards, so that the limiting block 701 is stuck between the U-shaped limiting frame 601 and the support plate 2, so that the limiting block 701 limits the U-shaped limiting frame 601. At this time, the personnel can directly release their hands without having to keep pulling the handle 607, saving manpower and making it easier for personnel to operate. The structure is simple and highly practical.

[0036] Furthermore, the limiting block 701 is made of iron, and a T-shaped slider 702 is fixedly installed on the inner side of the limiting block 701. A T-shaped groove 703 is opened on the outer side of the support plate 2, and the T-shaped slider 702 is slidably connected to the T-shaped groove 703.

[0037] By setting T-shaped slider 702 and T-shaped groove 703, the limiting block 701 can be fixedly slid on the support plate 2.

[0038] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
