Description

Technical Field

[0001] This utility model relates to the field of ceramic fixture technology, and in particular to a fixture for processing equipment for ceramic preform components. Background Technology

[0002] Ceramic preforms, due to their high strength, high temperature resistance, corrosion resistance, and excellent insulation properties, are widely used in the manufacture of various core components. Before being put into practical use, ceramic preforms need to undergo precision processing such as cutting, grinding, and drilling using specialized processing equipment. Stable clamping and flexible angle adjustment of the ceramic preforms during processing are key steps to ensure processing accuracy and avoid damage to the workpiece.

[0003] However, most existing fixtures are designed for single workpieces with fixed clamping spacing and clamping range. When processing ceramic preforms of different sizes and specifications, it is necessary to replace the entire set of fixtures or make complex structural adjustments, which not only increases the cost of equipment investment but also prolongs the process changeover time and results in low production efficiency. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a clamping device for processing ceramic preform components, which effectively solves the problem that existing clamping devices are mostly designed for single workpieces and have fixed clamping spacing and clamping range.

[0005] The technical solution adopted by this utility model to solve the above problems is as follows: A fixture for processing ceramic preform components includes a base. A self-locking deflection assembly is provided on the upper end of the base. The self-locking deflection assembly includes a mounting column rotatably connected to the base. A plurality of mounting frames are fixedly installed at equal intervals on the mounting column. A clamping assembly for clamping ceramic preforms is provided on the mounting frame. The clamping assembly includes a pair of first fixing posts fixedly installed at the front end of the mounting frame. A second fixing post corresponding to the first fixing posts is slidably provided at the rear end of the mounting frame. The second fixing posts are all fixedly installed on a mounting rod. One end of the mounting rod is rotatably connected to a support rod rotatably connected to the base.

[0006] The self-locking deflection assembly includes a worm gear rotatably connected to the base, a rotating rod coaxially fixedly connected to the mounting column, and a worm wheel meshing with the worm gear fixedly connected to one end of the rotating rod.

[0007] The lower end of the second fixing column is provided with a pin that is slidably connected to the inner wall of the mounting frame, and the ceramic preform is disposed between the first fixing column and the second fixing column.

[0008] The inner wall of the mounting bracket is provided with a sliding groove that matches the pin. The pin slides along the length of the sliding groove, and the length of the sliding groove is greater than the movement distance of the second fixed column from clamping the ceramic preform to the released state.

[0009] Both the first and second fixing posts are wrapped with an elastic buffer layer at the end near the ceramic preform, and the elastic buffer layer is made of rubber.

[0010] The number of mounting brackets is 4, and the included angle between adjacent mounting brackets is equal.

[0011] Compared with the prior art, this utility model has the following advantages: The ceramic preform is clamped and fixed using the first and second fixing posts. The distance between the second and first fixing posts can be adjusted by changing the rotation angle of the mounting column according to the size of the ceramic preform, thereby achieving precise clamping of ceramic preforms of different sizes and specifications. This facilitates subsequent processing, eliminates the need to change the fixture, and effectively improves production efficiency. Attached Figure Description

Detailed Implementation

[0013] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0014] like Figure 1-4As shown, a fixture for processing ceramic preform components includes a base 1. A self-locking deflection assembly is provided on the upper end of the base 1. The self-locking deflection assembly includes a mounting column 6 rotatably connected to the base 1. Several mounting frames 10 are fixedly installed at equal intervals on the mounting column 6. The mounting frames 10 are provided with clamping components for clamping ceramic preforms 8. The clamping components include a pair of first fixing posts 9 fixedly installed at the front end of the mounting frames 10. A second fixing post 11 corresponding to the first fixing post 9 is slidably provided at the rear end of the mounting frames 10. The second fixing posts 11 are all fixedly installed on mounting rods 7. One end of the mounting rods 7 is rotatably connected to a support rod 2 rotatably connected to the base 1.

[0015] The self-locking deflection assembly includes a worm gear 4 rotatably connected to the base 1, a rotating rod 13 coaxially fixedly connected to the mounting column 6, and a worm wheel 5 meshing with the worm gear 4 fixedly connected to one end of the rotating rod 13.

[0016] like Figure 4 As shown, a handle 3 is provided at the end of the worm 4. The worm 4 meshes with the worm wheel 5 at the end of the rotating rod 13, which is coaxial with the mounting column 6. By rotating the worm 4, the worm wheel 5 and the rotating rod 13 are driven to rotate synchronously. When the rotating rod 13 rotates, it will drive the mounting column 6 to rotate. Several mounting brackets 10 on the mounting column 6 will deflect synchronously. Since the meshing structure of the worm 4 and the worm wheel 5 has a self-locking characteristic, after the worm 4 stops rotating, the angle of the mounting column 6 and the mounting brackets 10 will remain fixed, without the need for an additional locking mechanism, thus ensuring the stability of the workpiece angle during the processing.

[0017] The lower end of the second fixing column 11 is provided with a pin 12 that is slidably connected to the inner wall of the mounting bracket 10, and the ceramic preform 8 is disposed between the first fixing column 9 and the second fixing column 11.

[0018] like Figure 2 and 3 As shown, by setting the pin 12, the movement trajectory of the second fixed column 11 can be precisely constrained, avoiding the second fixed column 11 from shifting or tilting when it moves with the mounting rod 7, ensuring that the second fixed column 11 always remains relatively parallel to the first fixed column 9, thereby ensuring that the clamping force on the ceramic preform 8 is evenly distributed, and preventing workpiece damage or decreased processing accuracy due to clamping misalignment.

[0019] The inner wall of the mounting bracket 10 is provided with a sliding groove that matches the pin 12. The pin 12 slides along the length of the sliding groove, and the length of the sliding groove is greater than the moving distance of the second fixing column 11 from clamping the ceramic preform 8 to the released state.

[0020] like Figure 2As shown, the length of the sliding groove is greater than the moving distance of the second fixed column 11 from clamping to releasing, which can ensure that the second fixed column 11 can slide to a sufficiently far position when releasing the workpiece, providing sufficient loading and unloading space for ceramic preforms 8 of different sizes, avoiding the inability to smoothly put in or take out the workpiece due to insufficient sliding stroke, and also reserving an operating margin for subsequent adjustment of the clamping distance to adapt to various specifications of workpieces.

[0021] The first fixing post 9 and the second fixing post 11 are both wrapped with an elastic buffer layer 14 at the end near the ceramic preform 8. The elastic buffer layer 14 is made of rubber.

[0022] like Figure 2 As shown, the rubber material has a high coefficient of friction. Compared with a smooth metal surface, it can significantly increase the friction between the first fixing post 9, the second fixing post 11 and the ceramic preform 8, prevent the workpiece from slipping or shifting during processing, and ensure that the workpiece is always in a precise clamping position, thereby indirectly ensuring processing accuracy. At the same time, the elastic buffer layer 14 can adapt to the slight unevenness of the surface of the ceramic preform 8, and fill the tiny gaps through deformation, further enhancing the clamping fit and stability.

[0023] The number of mounting brackets 10 is 4, and the included angle between adjacent mounting brackets 10 is equal.

[0024] like Figure 1 As shown, by setting multiple mounting brackets 10, multiple ceramic preforms 8 can be processed simultaneously, and the included angles are the same, which can avoid mutual interference during the processing of ceramic preforms 8.

[0025] The working process of this utility model is as follows: The ceramic preform 8 to be processed is placed between the first fixed post 9 and the second fixed post 11, ensuring that the workpiece is centered and fits against the elastic buffer layer 14 of the first fixed post 9. By operating the handle 3 at the end of the worm gear 4, the worm gear 4 meshes with the worm wheel 5 at the end of the rotating rod 13 coaxial with the mounting rotating post 6, driving the worm wheel 5 and the rotating rod 13 to rotate synchronously. When the rotating rod 13 rotates, it will drive the mounting rotating post 6 to rotate, and the four mounting brackets 10 on the mounting rotating post 6 will deflect synchronously. Since the meshing structure of the worm gear 4 and the worm wheel 5 has a self-locking characteristic, after the worm gear 4 stops rotating, the angle of the mounting rotating post 6 and the mounting brackets 10 will remain fixed, without the need for an additional locking mechanism, ensuring the stability of the workpiece angle during the processing.

[0026] Since one end of the support rod 2 is fixed and rotatably mounted on the base 1, the mounting rod 7 at one end of the second fixed column 11 will cause the support rod 2 at one end of the mounting rod 7 to deflect as the mounting rotating column 6 rotates. Since the distance between the mounting rod 7 and the pivot point between the support rod 2 and the base 1 becomes shorter, the support rod 2 drives the second fixed column 11 to slide upward along the inner wall of the mounting frame 10 under the action of the pin 12, thereby shortening the distance between the second fixed column 11 and the first fixed column 9. The ceramic preform 8 is clamped and fixed by the first fixed column 9 and the second fixed column 11. The distance between the second fixed column 11 and the first fixed column 9 can be adjusted by changing the rotation angle of the mounting rotating column 6 according to the size of the ceramic preform 8, thereby achieving precise clamping of ceramic preforms 8 of different sizes and specifications, facilitating subsequent processing, eliminating the need to change the fixture, and effectively improving production efficiency.

[0027] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
