Description

Technical Field

[0001] This utility model relates to the technical field of rotary parts processing equipment, and in particular to an internal support fixture for rotary parts used in photoelectric radar. Background Technology

[0002] In the machining of rotating parts in optoelectronic radar, rotating parts (such as radomes, rotor supports, etc.) generally adopt a hollow thin-walled structure to achieve lightweighting and functional integration. In the CNC machining process of such parts, especially when machining their outer contours, mounting holes and precision features, how to clamp them stably and reliably is the key challenge to ensure machining accuracy.

[0003] Currently, when clamping such parts, traditional external clamping fixtures are prone to causing extrusion deformation of thin-walled workpieces. Therefore, internal support fixtures are mostly used for internal support. However, existing internal support fixtures still have the following shortcomings in use: 1. Conventional internal support fixtures are mostly simple planes, while the internal cavities of rotating parts are often complex structures, making it difficult to effectively fit the internal support of the parts. 2. In order to ensure the effect of internal support, the existing internal support fixtures are often attached to the inner wall of the part's cavity. This causes the air in the inner cavity to be sealed and unable to be discharged when the workpiece is placed on the internal support fixture, forming an "air cushion effect". As a result, the workpiece cannot be fully positioned and fits against the internal support body, leading to inaccurate positioning reference and vibration under the action of cutting force, which seriously affects the hole position accuracy and surface machining quality. 3. After processing, the workpiece and the inner support are tightly fitted together, which not only easily forms a vacuum adsorption effect, but also makes it difficult to disassemble the workpiece even with slight deviation, resulting in low workpiece unloading efficiency. Therefore, there is an urgent need for a type of internal support fixture for rotating parts used in optoelectronic radar that can overcome the above-mentioned shortcomings. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model discloses an internal support tooling for rotating parts of photoelectric radar. When internally supporting thin-walled cavities, this utility model can not only provide stable and efficient internal support for the workpiece, but also effectively solve the problems of air cushion effect, positioning inaccuracy and disassembly difficulty when internally supporting thin-walled cavities.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A rotating component internal support fixture for photoelectric radar includes a base and further includes: An inner support component, located on the upper part of the base, is adapted to the contour of the inner cavity of the workpiece and is used to provide internal support for the inner cavity of a thin-walled hollow workpiece. The clearance groove is located on the upper surface of the inner support member, and the shape of the clearance groove matches the internal structure of the workpiece cavity. The positioning hole is located on the upper surface of the inner support member. It is used to accommodate the positioning element and mate with the pre-made hole of the workpiece to fix the workpiece on the inner support member. Several strip-shaped grooves are vertically arranged on the side wall of the inner support and evenly distributed along the circumference of the inner support. Both the upper and lower ends of the strip-shaped grooves are open structures, which are used to form exhaust channels when the workpiece is fastened to the inner support. The push plate is located outside the inner support member. The push plate can move up and down in the vertical direction to support and lift the workpiece when it is raised, so that the workpiece is separated from the inner support member.

[0006] Furthermore, the push plate has a through-hole in the middle that fits the outer contour of the inner support member, and the push plate is fitted onto the outside of the inner support member through the through-hole.

[0007] Furthermore, the inner wall of the passage is provided with multiple support rods that correspond one-to-one with the strip grooves on the outer wall of the inner support member. There is a gap between the inner surface of the support rod and the bottom surface of the strip groove, and the outer surface of the support rod is coplanar with the side wall of the inner support member.

[0008] Furthermore, both inner walls of the strip groove are provided with protruding ribs arranged along the axial direction of the strip groove, and both sides of the inner surface of the support rod are provided with recesses that correspond to the protruding ribs and engage with them.

[0009] Furthermore, the base includes a base plate and a support block located on the upper part of the base plate, with an inner support member detachably installed on the upper part of the support block.

[0010] Furthermore, the upper part of the base plate is provided with a telescopic cylinder surrounding the support block, and the output end of the telescopic cylinder is connected to the push plate.

[0011] Furthermore, the upper side of the support block sidewall is provided with several mounting screw holes evenly distributed along the circumference of the support block, the lower surface of the inner support member is provided with a groove adapted to the support block, and the outer side wall of the groove is provided with several recessed screw holes that correspond one-to-one with the mounting screw holes.

[0012] Furthermore, the upper surface of the inner support is provided with a countersunk hole corresponding to the hole to be machined on the workpiece.

[0013] Compared with the prior art, the beneficial effects of this utility model are: By setting the clearance groove, the inner support can effectively avoid the structure of the workpiece's inner cavity when supporting the workpiece, providing strong support for the inner support to fully and stably support the workpiece. By setting a vertically penetrating strip groove on the side wall of the inner support, an efficient exhaust channel is provided for the air in the inner cavity when the workpiece is fastened, which completely avoids the air cushion effect caused by air stagnation, ensuring that the workpiece can quickly and tightly fit the upper surface of the inner support, establishing a stable and reliable positioning reference, and eliminating the processing error caused by improper clamping from the source. By incorporating a push plate, the workpiece can be smoothly lifted after processing, allowing it to separate easily from the inner support. This mechanical ejection structure overcomes the adhesion and friction between the workpiece and the inner support, enabling fast, convenient, and non-destructive unloading operations, significantly improving production efficiency and operational safety. The system is equipped with a support rod that can be inserted into the slot, which not only makes the outer surface of the support rod coplanar with the side wall of the inner support component, forming a complete and continuous support plane for the side wall of the workpiece's inner cavity, thus compensating for the weakening of the side wall support by the slot, but also greatly enhances the overall rigidity of the workpiece during processing and effectively suppresses cutting vibration. Furthermore, it can work in conjunction with the push plate to lift and unload the workpiece, effectively avoiding the situation where the push plate alone lifts the thin wall of the workpiece, which can easily cause thin wall deformation. By setting protruding ridges, the support rod can be effectively vertically limited, thereby ensuring that the support rod is always coplanar with the side wall of the support component, providing a strong guarantee for the stability of the workpiece during the processing. By designing detachable internal support components, a single base and jacking system can be adapted to various workpiece models by replacing internal support components with different profiles, greatly improving the versatility of tooling and the flexible production capacity of the production line. This invention not only provides stable and efficient internal support for thin-walled cavities, but also effectively solves the problems of air cushion effect, positioning inaccuracy, and disassembly difficulties when internally supporting thin-walled cavities. This invention significantly enhances processing rigidity and improves the versatility and flexibility of tooling, providing strong support for high-precision, high-efficiency, and high-stability processing of workpieces.

[0016] The technical solution of this utility model will be described below with reference to the accompanying drawings of the embodiments of this utility model. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this utility model for the convenience of describing this utility model, and do not indicate or imply that the device or element referred to must have a specific orientation.

[0017] Please refer to the instruction manual appendix. Figure 1-6 This utility model provides a technical solution: Example 1: A tooling for supporting rotating parts for photoelectric radar includes a base 3, the base 3 includes a bottom plate 3.1 and a support block 3.2 disposed on the upper part of the bottom plate 3.1. The upper part of the support block 3.2 is provided with an inner support member 1, which is adapted to the inner cavity contour of the workpiece and is used to support the inner cavity of the thin-walled hollow workpiece. In order to achieve stable and effective internal support for the workpiece by the inner support member 1, the upper surface of the inner support member 1 is provided with a relief groove 1.1 that matches the internal structure of the workpiece cavity. During the fastening process, the protruding structure of the workpiece cavity can be embedded in the relief groove 1.1, thereby achieving effective internal support for the workpiece cavity by the inner support member 1. To ensure the workpiece is securely fastened, the upper surface of the inner support 1 is provided with multiple positioning holes 1.2 corresponding to the pre-drilled holes on the workpiece. Positioning elements, such as positioning screws and expansion screws, are installed in the corresponding positioning holes 1.2 and the pre-drilled holes on the workpiece, thereby fixing the workpiece and providing strong support for the high-quality processing of the workpiece in the future. During the workpiece fastening process, because the inner support 1 is tightly attached to the inner cavity of the workpiece, the air in the inner cavity of the workpiece cannot be effectively discharged. This not only easily forms an air cushion effect, that is, the air will prevent the workpiece from being completely and tightly attached to the inner support 1, but may also lead to problems such as inaccurate positioning or processing vibration. In order to enable the workpiece to smoothly discharge the air in the inner cavity during the fastening process, the side wall of the support 1 is provided with multiple vertical strip grooves 1.4 that are evenly distributed around the circumference of the inner support 1. The upper and lower ends of the strip grooves 1.4 are open structures. When the workpiece is fastened on the inner support 1, the air in the cavity of the workpiece is discharged to the outside through the strip grooves 1.4. During the workpiece unloading process, the inner support 1 is tightly attached to the inner cavity of the workpiece, making the unloading operation very difficult. In order to achieve a fast unloading operation of the workpiece, a push plate 2 is provided on the outside of the support 1. The push plate 2 has a through-hole 2.1 in the middle that is adapted to the outer contour of the inner support 1. The push plate 2 is sleeved on the outside of the inner support 1 through the through-hole 2.1. A telescopic cylinder 3.3 is provided on the upper part of the bottom plate 3.1. The output end of the telescopic cylinder 3.3 is connected to the push plate 2. After the push plate 2 rises, it abuts against the side wall of the workpiece. As the push plate 2 continues to rise, it can lift the workpiece and make it quickly detach from the inner support 1.

[0018] In the second embodiment, during the internal support process of a hollow thin-walled workpiece, the setting of the strip groove 1.4 prevents the internal support member 1 from providing tight and stable internal support for the workpiece sidewall. If the processing position corresponds to the strip groove 1.4 during the processing of the workpiece sidewall, it will have an adverse effect on the processing of the workpiece. Therefore, in order to ensure that the strip groove 1.4 can effectively vent air while providing tight and stable internal support for the workpiece sidewall, the inner wall of the through 2.1 is provided with multiple support rods 2.2 that correspond one-to-one with the strip groove 1.4 on the outer wall of the internal support member 1. There is a gap between the inner surface of the support rod 2.2 and the inner bottom surface of the strip groove 1.4, and the outer surface of the support rod 2.2 is coplanar with the sidewall of the internal support member 1. In addition, when the support rod 2.2 is inserted into the strip groove 1.4, the upper end of the support rod 2.2 is coplanar with the upper surface of the internal support member 1. To ensure that the support rod 2.2 remains vertically stable within the slot 1.4, both inner sidewalls of the slot 1.4 are provided with protruding ribs 1.4.1 arranged along the axial direction of the slot 1.4. Both sides of the inner surface of the support rod 2.2 are provided with recesses 2.2.1 that correspond to and engage with the protruding ribs 1.4.1. By using the protruding ribs 1.4.1 to stop and limit the slot 1.4, the support rod 2.2 can remain coplanar with the sidewall of the inner support member 1 even when subjected to external forces.

[0019] In Example 3, when different workpieces need to be processed with internal supports, it is necessary to replace the inner support component 1 with a suitable one. In order to replace the inner support component 1, the upper side wall of the support block 3.2 is provided with several mounting screw holes 3.2.1 evenly distributed around the circumference of the support block 3.2. The lower surface of the inner support component 1 is provided with a groove 1.5 that matches the support block 3.2. The outer wall of the groove 1.5 is provided with several recessed screw holes 1.6 that correspond one-to-one with the mounting screw holes 3.2.1. Fastening screws are provided in the corresponding recessed screw holes 1.6 and mounting screw holes 3.2.1. By opening grooves 1.5 of the same size at the lower part of inner support components 1 of different shapes, the inner support component 1 can be conveniently and efficiently disassembled and assembled when it is replaced.

[0020] In Example 4, when drilling a hole in a workpiece, the inner support 1 is tightly attached to the inner cavity of the workpiece. When drilling a through hole, the cutting tool is very likely to come into contact with the inner support 1, which can damage the inner support 1 and affect the subsequent horizontal stability of the workpiece. To avoid wear of the inner support 1 by the cutting tool during drilling, the inner support 1 is provided with a countersunk hole 1.3 corresponding to the hole to be machined on the workpiece. Since the workpieces are often processed in large quantities in the same batch, it is only necessary to pre-open the countersunk hole 1.3 corresponding to the hole to be machined on the workpiece on the inner support 1 to effectively avoid wear of the inner support 1 by the cutting tool.
