Description

Technical Field

[0001] This utility model relates to the field of parts processing technology, specifically to a tooling fixture for disc-shaped parts and a drilling device for disc-shaped parts. Background Technology

[0002] In the field of accelerator tube machining, disc-shaped parts generally have a thin-walled structure, which makes them prone to deformation during clamping. Once deformed, it not only affects the machining accuracy of the tuning hole but may also lead to the scrapping of the part, increasing production costs. At the same time, the irregular shape makes it difficult for existing clamping methods to effectively fix the part, and the part is prone to loosening and displacement during machining, resulting in positional deviations and dimensional errors of the tuning hole. Utility Model Content

[0003] This utility model is based on the inventor's discovery and understanding of the following facts and problems:

[0004] In accelerator tube manufacturing, tuning holes are located circumferentially on disk-like parts, serving to precisely adjust the accelerator tube's resonant frequency and energy transfer efficiency. While this design functionally meets the high-performance requirements of accelerator tubes, it presents unprecedented challenges to clamping and securing them during manufacturing. Because the tuning holes are distributed circumferentially, disk-like parts lack sufficient support surfaces and clamping points in this direction, making traditional clamping methods ineffective. However, failure to securely clamp and fix the disk-like parts can significantly reduce the machining accuracy of the tuning holes, leading to issues such as hole diameter deviation and inconsistent hole spacing, thereby affecting the accelerator tube's resonant characteristics and energy transfer stability.

[0005] Therefore, embodiments of this utility model propose a tooling fixture for disc-shaped parts and a drilling device for disc-shaped parts, which can efficiently fix and tune the processing of holes in disc-shaped parts, and help ensure the stability of the parts during the processing.

[0006] The tooling fixture for disc-shaped parts provided in this embodiment of the utility model includes a base and a clamping assembly. The base includes a bottom plate and multiple side plates, which are spaced apart on the bottom plate. The bottom plate and the multiple side plates enclose a fixing cavity. The side plates are provided with mounting holes that communicate with the fixing cavity. The fixing cavity is used to place disc-shaped parts. A drilling guide cavity is provided between two adjacent side plates. The clamping assembly is provided in a one-to-one correspondence with the mounting holes. The clamping assembly includes a contact ball, an elastic element, and a fixing post. The two ends of the elastic element are connected to the contact ball and the fixing post respectively. The fixing post and the contact ball are located at the two ends of the mounting holes. At least a portion of the contact ball protrudes into the fixing cavity. The contact ball is used to abut against the disc-shaped parts.

[0007] In summary, the disc-shaped parts tooling fixture provided by this utility model achieves high-precision and high-efficiency fixing and processing of disc-shaped parts through the cooperation of the base and the clamping assembly. Furthermore, the clamping assembly can achieve multi-angle clamping methods, which helps ensure the stability of the parts during processing, while the drilling guide cavity further improves the precision and accuracy of drilling operations.

[0008] In some embodiments, the mounting hole includes a first hole segment and a second hole segment connected to each other, wherein the diameter of the first hole segment is smaller than the diameter of the abutment ball, and the diameter of the second hole segment is greater than or equal to the diameter of the abutment ball.

[0009] In some embodiments, the mounting hole further includes a threaded hole section, the threaded hole section and the first hole section are disposed opposite each other on both sides of the second hole section, and the fixing post is provided with an external thread section that matches the threaded hole section.

[0010] In some embodiments, the clamping assembly further includes an anti-loosening washer fitted onto the fixing post.

[0011] In some embodiments, the end of the fixing post is provided with a cross groove.

[0012] In some embodiments, the base plate has heat dissipation holes in the middle.

[0013] In some embodiments, the base plate has a lower surface with anti-slip texture, the anti-slip texture having intersecting grid-like protrusions, the height of the protrusions being 0.5-1mm.

[0014] In some embodiments, the base plate has an upper surface opposite to the lower surface, the upper surface is provided with reinforcing ribs, the radial cross section of the reinforcing ribs is trapezoidal, and the height of the reinforcing ribs is set to 1 mm to 2 mm.

[0015] In some embodiments, the side plate has a first plane and a second plane disposed opposite to each other, the first plane and the second plane being parallel to each other, and the first plane and the second plane being used to cooperate with the grippers on the drilling equipment.

[0016] In addition, the drilling equipment for disc-shaped parts provided by this utility model includes a processing platform and a disc-shaped part tooling fixture as described in any of the above embodiments.

[0023] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] like Figures 1 to 3 As shown, an embodiment of the present invention provides a tooling fixture for disc-shaped parts, which includes a base 10 and a clamping assembly 20. The base 10 includes a base plate 11 and a plurality of side plates 13. The plurality of side plates 13 are spaced apart on the base plate 11. The base plate 11 and the plurality of side plates 13 enclose a fixing cavity 15. The side plates 13 are provided with mounting holes 14, which are connected to the fixing cavity 15. The fixing cavity 15 is used to place disc-shaped parts. A drilling guide cavity 17 is provided between two adjacent side plates 13. The clamping assembly 20 is provided in a one-to-one correspondence with the mounting hole 14. The clamping assembly 20 is located in the mounting hole 14. The clamping assembly 20 includes a contact ball 21, an elastic element 23 and a fixing post 25. The two ends of the elastic element 23 are connected to the contact ball 21 and the fixing post 25 respectively. The fixing post 25 and the contact ball 21 are located at the two ends of the mounting hole 14 respectively. At least part of the contact ball 21 protrudes into the fixing cavity 15. The contact ball 21 is used to contact the disc-type part 100.

[0025] Specifically, multiple side plates 13 are spaced equally around the central axis of the base plate 11 and fixed to the base plate 11, thus collectively enclosing a closed or semi-closed fixing cavity 15. The shape and size of the fixing cavity 15 match the outer contour of the disc-shaped part 100 to be processed, ensuring that the part is accurately placed within it. A drilling guide cavity 17 is also provided between two adjacent side plates 13, which can guide the drilling equipment to operate along a predetermined path, avoiding processing errors caused by offset.

[0026] The elastic element 23 is tightly connected at both ends to the contact ball 21 and the fixing post 25, respectively. When not subjected to external force, the elastic element 23 is in its natural state. At this time, under the action of the elastic element 23, at least a portion of the contact ball 21 protrudes into the fixing cavity 15, forming slight contact with the surface of the disc-shaped part 100 placed therein. When the disc-shaped part 100 is placed into the fixing cavity 15, as the fixing post 25 moves further towards the fixing cavity 15, the elastic element 23 is compressed, thereby pushing the contact ball 21 to fit more tightly against the surface of the disc-shaped part 100, achieving multi-angle, all-around stable clamping. This not only ensures the positional stability of the disc-shaped part 100 during processing but also avoids deformation or damage to the part due to excessive clamping force.

[0027] In summary, this utility model's tooling fixture for disc-shaped parts achieves high-precision and high-efficiency fixing and processing of disc-shaped parts through the cooperation of the base 10 and the clamping assembly 20. Furthermore, the clamping assembly 20 can achieve multi-angle clamping methods, which helps ensure the stability of the parts during processing, while the drilling guide cavity 17 further improves the precision and accuracy of drilling operations.

[0028] like Figure 2 As shown, in this embodiment, two side plates 13 are provided, which can provide a more stable support structure for the tooling fixture. The two side plates 13 are symmetrically arranged on the base plate 11. Through the tight connection between the base plate 11 and the side plates 13, not only can the shaking or displacement of the disc-shaped part 100 during the processing be effectively prevented, but also the drilling equipment can maintain stable positioning during operation, thereby improving processing accuracy and efficiency. Optionally, the side plates 13 can be integrated with the base plate 11.

[0029] Furthermore, the side plate 13 may be provided with a scale to facilitate determining the position of the tuning hole in the disk-type part 100.

[0030] like Figure 1 and Figure 3As shown, in some embodiments, the mounting hole 14 includes a first hole segment 142 and a second hole segment 144 connected to each other. The diameter of the first hole segment 142 is smaller than the diameter of the abutment ball 21, and the diameter of the second hole segment 144 is greater than or equal to the diameter of the abutment ball 21. When the abutment ball 21 attempts to pass through the first hole segment 142 under the action of the elastic member 23, it is subject to certain restrictions, thereby ensuring that the abutment ball 21 can be stably held within the mounting hole 14 when not compressed by external force, and will not fall out accidentally. At the same time, it also ensures that the abutment ball 21 receives sufficient support force during clamping to achieve effective clamping of the disc-type part 100.

[0031] The diameter of the second hole 144 is greater than or equal to the diameter of the contact ball 21, providing sufficient space for the contact ball 21 to move. When the clamping assembly 20 clamps the disc-shaped part 100, the elastic element 23 is compressed, and the contact ball 21 can move freely within the second hole 144 until it is tightly fitted against the surface of the part. This design ensures effective transmission of clamping force while avoiding problems such as obstructed movement of the contact ball 21 or excessive compression of the elastic element 23 due to an excessively small hole diameter.

[0032] Optionally, the elastic element 23 can be a spring.

[0033] Furthermore, the mounting hole 14 also includes a threaded hole section 146, which is positioned opposite to the first hole section 142 on both sides of the second hole section 144. The fixing post 25 is provided with an external thread section 252 that matches the threaded hole section 146. That is, by rotating the fixing post 25, it can be precisely moved along the threaded hole section 146, thereby achieving fine adjustment of the clamping assembly 20. This design not only facilitates the assembly and disassembly of the fixture, but also makes the adjustment of the clamping force more flexible and accurate.

[0034] Furthermore, the clamping assembly 20 also includes an anti-loosening washer, which is fitted onto the fixing post 25. During the operation of the clamp, the anti-loosening washer can effectively prevent the fixing post 25 from loosening due to vibration or external force, thereby ensuring that the clamping assembly 20 always maintains a stable clamping state. At the same time, the anti-loosening washer can also play a certain buffering role, reducing damage to the surface of the part caused by excessive clamping force.

[0035] In this embodiment, the end of the fixing post 25 is provided with a cross groove 254. During the assembly or use of the tooling fixture, when it is necessary to adjust the position or clamping force of the clamping assembly 20, the operator can easily rotate the fixing post 25 using a screwdriver or special tool that matches the cross groove 254. This allows the rotation of the fixing post 25 to be more stable and powerful, and the rotation angle can be precisely controlled, thereby achieving fine adjustment of the clamping assembly 20.

[0036] In some embodiments, the base plate 11 is provided with heat dissipation holes 112 in the middle, which can effectively address the problem of heat accumulation that may occur during long-term operation of the tooling fixture, and also reduce the weight of the tooling fixture.

[0037] In some embodiments, the base plate 11 has a lower surface 114, which is provided with anti-slip texture. The anti-slip texture has cross-grid protrusions with a height of 0.5-1mm, which not only improves the friction between the base plate 11 and the placement surface, but also significantly enhances the stability of the tooling fixture during operation.

[0038] Specifically, these anti-slip patterns are designed as a cross-grid-like raised structure. Compared to patterns in a single direction or with a simple shape, this structure can more effectively distribute pressure and increase the contact area, thus providing a more uniform and powerful anti-slip effect. Whether on smooth metal surfaces, wooden workbenches, or other materials, this cross-grid-like anti-slip pattern ensures that tooling fixtures remain stable and prevents processing errors or safety accidents caused by accidental slippage.

[0039] Furthermore, the height of these protrusions is precisely controlled between 0.5-1mm; for example, the height can be set to 0.5mm, 0.7mm, 0.8mm, or 1mm. This height selection is not arbitrary but rather the optimal solution derived after extensive experimentation and practical application verification. If the protrusion height is too low, it may not provide sufficient friction, resulting in poor anti-slip performance; conversely, if the protrusion height is too high, it may increase the contact resistance between the base plate 11 and the placement surface, affecting the flexible movement and adjustment of the tooling fixture, and may even damage the placement surface due to excessive local pressure. Therefore, a protrusion height of 0.5-1mm ensures both anti-slip performance and the flexibility and safety of the tooling fixture.

[0040] Furthermore, the base plate 11 has an upper surface 116 opposite to the lower surface 114. The upper surface 116 is provided with reinforcing ribs, the radial cross-section of which is trapezoidal, and the height of which is set to 1mm to 2mm. This not only facilitates the placement of the disc-shaped parts 100 but also improves the structural strength of the base plate 11. In this embodiment, the upper surface 114 and the lower surface 116 are arranged opposite each other in the thickness direction of the base plate 11.

[0041] Optionally, the height of the reinforcing rib can be set to 1mm, 1.5mm, or 2mm, etc. This height selection takes into account both the need to improve the structural strength of the base plate 11 and the overall weight and processing convenience of the tooling fixture. If the height of the reinforcing rib is too low, it may not provide sufficient reinforcement, and the base plate 11 may still deform significantly under stress; while if the height of the reinforcing rib is too high, it will increase the overall weight of the tooling fixture, affecting the flexibility and ease of operation during processing, and may even place an additional burden on the processing equipment due to excessive weight.

[0042] like Figure 2 As shown, in some embodiments, the side plate 13 has a first plane 132 and a second plane 134 arranged opposite to each other. The first plane 132 and the second plane 134 are parallel to each other and are used to cooperate with the grippers on the drilling equipment. That is, the first plane 132 and the second plane 134 can provide a stable and reliable clamping surface for the grippers of the drilling equipment. During the drilling operation, the grippers need to firmly hold the tooling fixture to ensure the accuracy and stability of the drilling. The two parallel planes on the side plate 13 provide ideal clamping points for the grippers, allowing the grippers to fit tightly against the side plate 13, thereby effectively preventing the tooling fixture from shaking or shifting during the drilling process.

[0043] In addition, one embodiment of the present invention provides a drilling device for disc-shaped parts, which includes a processing platform and a disc-shaped part tooling fixture provided in any of the above embodiments. The processing platform is provided with jaws, which clamp the first plane 132 and the second plane 134 to fix the disc-shaped part tooling fixture.
