Description

Technical Field

[0001] The utility model belongs to the technical field of graphite processing parts, and in particular relates to a tooling for preventing deformation of thin-walled parts. Background Art

[0002] Graphite is a carbon-containing inorganic material with unique physical and chemical properties. Its structure and properties make it widely used in many fields, including graphite parts produced using graphite as raw material.

[0003] The existing processing of graphite parts generally relies on CNC machine tools. However, when clamping and fixing the graphite parts, the conventional three-jaw chuck will cause extrusion deformation on the outside of the graphite parts themselves. Especially when processing relatively thin graphite parts, it will cause damage to the graphite parts themselves, thereby reducing the processing and production efficiency of graphite parts. For this reason, we have proposed a thin-walled part anti-deformation tooling to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to provide a thin-walled component anti-deformation tooling to solve the problems existing in the background technology.

[0005] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0006] The anti-deformation tooling for thin-walled parts includes a mounting plate, a circular through groove is opened in the middle of the upper end of the mounting plate, a plurality of mounting grooves are opened on the upper end of the mounting plate, and each of the mounting grooves is evenly distributed around the circular through groove, a graphite strip is pasted inside each of the mounting grooves, a plurality of card slots are opened on the upper end of each of the graphite strips, a plurality of evenly distributed fixing holes are opened on the upper end of the mounting plate, three pressure blocks are provided on the upper end of each of the pressure blocks, a through hole is opened on the upper end of each of the pressure blocks, and the fixing holes are threadedly connected with fixing bolts that pass through each of the through holes respectively.

[0007] Furthermore, the inner wall of the circular through groove is provided with anti-slip grooves.

[0008] Furthermore, each of the card slots is arranged in a stepped shape.

[0009] Furthermore, one end of each of the graphite strips overlaps with the inner wall of the circular through groove, and the other end of each of the graphite strips overlaps with the outer side of the mounting plate.

[0010] Furthermore, the three pressing blocks are distributed in a triangle.

[0011] Furthermore, threaded holes are formed on the upper ends of the three pressing blocks, and each of the threaded holes is close to the outer side of the mounting plate.

[0012] Furthermore, each of the fixing holes gradually moves from the outer ring at the upper end of the mounting plate toward the center.

[0013] The beneficial effects of the utility model are:

[0014] 1) By arranging the mounting plate, the graphite strip and the pressure plate to cooperate with each other, the thin-walled graphite parts can be clamped and fixed, thereby facilitating the subsequent processing of the thin-walled graphite parts.

[0015] 2) By providing a plurality of graphite strips and opening a plurality of stepped slots on each graphite strip, it is convenient to clamp graphite parts of different sizes, thereby improving the application range of processing graphite parts.

[0016] 3) By arranging one end of the graphite strip to coincide with the circular through groove and the other end to coincide with the outer side of the mounting plate, it is convenient to quickly position the replaced graphite strip, so that the graphite part can be directly inserted into the slot, and the graphite part can be directly processed, thereby shortening the preparation time before processing the graphite part, and then improving the processing efficiency of subsequent graphite parts.

[0024] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0025] Embodiment 1:

[0026] like Figure 1-Figure 2As shown, the anti-deformation tooling for thin-walled parts includes a mounting plate 100, a circular through groove 101 is opened in the middle of the upper end of the mounting plate 100, a plurality of mounting grooves 102 are opened on the upper end of the mounting plate 100, and each mounting groove 102 is evenly distributed around the circular through groove 101, a graphite strip 103 is pasted inside each mounting groove 102, a plurality of card slots 104 are opened on the upper end of each graphite strip 103, a plurality of evenly distributed fixing holes 105 are opened on the upper end of the mounting plate 100, three pressing blocks 106 are provided on the upper end of each pressing block 106, a through hole 107 is opened on the upper end of each pressing block 106, and the fixing holes 105 are threadedly connected with fixing bolts that pass through each through hole 107 respectively.

[0027] The three-jaw chuck on the CNC machine tool can clamp the mounting plate 100 through the circular through groove 101, and the graphite strip 103 is pasted inside the mounting groove 102, which is convenient for the staff to replace the graphite strip 103. After the graphite strip 103 is installed, each slot 104 can be specially processed according to the size of the graphite parts to be clamped. Each graphite strip 103 can clamp the outside of the graphite part to prevent the graphite part from flying out when the three-jaw chuck is rotated, thereby affecting the processing of the graphite part. The fixing bolt can pass through the through hole 107 and be threadedly connected with the corresponding fixing hole 105 until each pressing block 106 abuts against the graphite part, thereby pressing the graphite part into the corresponding slots 104 on each graphite strip 103. In this way, thin-walled graphite parts can be processed, thereby preventing the thin-walled graphite parts from being deformed or damaged by being clamped, affecting the processing of the graphite parts.

[0028] Before processing the thin-walled graphite parts: first, insert the three-jaw chuck into the circular through groove 101, so that the mounting plate 100 can be clamped and fixed, and then, the graphite strips 103 are pasted inside each slot 104, and each graphite strip 103 is processed first according to the size of the graphite parts to be processed, and the corresponding slots 104 are opened, so that the graphite parts can be placed in the corresponding slots 104, so that the graphite parts are directly located at the central axis position of the three-jaw chuck, and the staff does not need to adjust the positioning, and the processing can be carried out directly. Finally, by screwing the fixing bolt, one end of the fixing bolt passing through the through hole 107 is threadedly connected with the corresponding fixing hole 105, and the direction of each pressing block 106 is adjusted so that each pressing block 106 points to the center of the circular through groove 101 until each pressing block 106 abuts against the graphite parts, so that the graphite parts can be completely clamped and fixed, thereby ensuring that the graphite parts will not be deformed or damaged when clamping the graphite parts, thereby improving the efficiency of graphite part processing.

[0029] In this embodiment, the outer side of the graphite parts can be clamped and restricted by the grooves 104 opened at the upper ends of the graphite strips 103, and then the fixing bolts drive the pressure blocks 106 to abut against the graphite parts, and the mounting plate 100 is used to clamp the graphite parts, so as to prevent the graphite parts from being damaged or deformed before processing, thereby affecting the efficiency of graphite part processing.

[0030] Embodiment 2:

[0031] Based on the first embodiment, the components on the thin-walled component anti-deformation tooling are further described. Figure 1-Figure 4 As shown, the inner wall of the circular through groove 101 is provided with anti-slip grooves.

[0032] Each of the card slots 104 is arranged in a stepped shape.

[0033] One end of each graphite strip 103 overlaps with the inner wall of the circular through groove 101 , and the other end of each graphite strip 103 overlaps with the outer side of the mounting plate 100 .

[0034] The three compacts 106 are distributed in a triangle.

[0035] A threaded hole 108 is formed at the upper end of each of the three pressing blocks 106 , and each threaded hole 108 is close to the outer side of the mounting plate 100 .

[0036] The fixing holes 105 gradually move from the outer ring at the upper end of the mounting plate 100 to the center.

[0037] In this embodiment, when the three-jaw chuck abuts against the inner wall of the circular groove 101, the anti-slip grooves on the inner wall of the circular groove 101 can increase the friction between the three-jaw chuck and the mounting plate 100 to prevent the three-jaw chuck from falling off when the three-jaw chuck rotates.

[0038] Each slot 104 is arranged in a stepped shape, so that graphite parts of various sizes can be processed without the need for workers to frequently replace each graphite strip 103, which can not only improve the processing efficiency of graphite parts, but also reduce the workload of workers.

[0039] When it is necessary to replace the processed graphite strip 103, it is only necessary to overlap one end of the replaced graphite strip 103 with the inner wall of the circular through groove 101 and the other end with the outer side of the mounting plate 100, so that the clamped graphite part can be quickly positioned on the center axis, and the graphite part can be directly processed, thereby improving the processing efficiency of the graphite parts.

[0040] The three pressing blocks 106 distributed in a triangular shape can better abut against the graphite parts, so that the clamping pressure on the graphite parts is equal, thus preventing the graphite parts from being squeezed, deformed or damaged.

[0041] An abutment rod can be threadedly connected inside the threaded hole 108, and the abutment rod will abut against the surface of the mounting plate 100, so as to support the corresponding pressing blocks 106, so that the unsupported side of each pressing block 106 close to the circular through groove 101 can be tightly abutted against the graphite part, thereby preventing shaking during the processing of the graphite part and affecting the processing of the graphite part.

[0042] The fixing holes 105 are not only evenly distributed on the circumference of the mounting plate 100, but also distributed between the outer ring and the inner ring of the mounting plate 100, so that they can be flexibly adjusted according to the size of the graphite parts to be processed, which is suitable for the processing of different parts.
