Description

Technical Field

[0001] This invention relates to the field of bow plate-type parts processing technology, and more specifically to tooling for batch processing of bow plate-type parts. Background Technology

[0002] As a crucial component of mechanical structures, bow-shaped parts play an irreplaceable role in various mechanical equipment due to their unique curvature and shape design. They serve multiple functions, acting as load-bearing bodies, support components, and connecting parts. They not only construct a stable frame structure providing fundamental support for the equipment but also ensure precise docking and force transmission between components, guaranteeing the normal operation and functional realization of the equipment. The curved surface design, while meeting specific mechanical requirements and enhancing structural stability, often integrates complex hole layouts with diverse hole specifications and arrangements, aiming to achieve precise fit with other components and ensure accurate positioning and secure fixation during assembly. Given the direct impact of hole machining accuracy on the assembly accuracy and operational performance of mechanical systems, stringent requirements are placed on the machining process of bow-shaped parts.

[0003] Currently, the machining efficiency of traditional bow-plate parts is low. The main reasons include: existing equipment typically only allows for single-piece clamping operations; in batch production, a clamping and changing operation is required after machining the holes of each part, severely hindering the continuity of the production process. Secondly, during workpiece positioning, operators must manually adjust and tighten the pressure plate nuts to ensure effective clamping of the bow plate, preventing positional deviations due to vibration or uneven force during machining, which would affect the hole machining quality. This process is both time-consuming and labor-intensive, increasing the worker's workload and reducing production efficiency.

[0004] Furthermore, processing bow-shaped parts using existing technology requires manual loading and unloading of workpieces after each processing cycle. Frequent start-ups and shutdowns not only extend non-productive time and reduce effective working time, but also exacerbate equipment wear and energy consumption, indirectly increasing operating costs. In addition, workpiece changes often involve the replacement or adjustment of cutting tools such as drill bits, further increasing the frequency and complexity of tool changes, leading to a decrease in overall equipment utilization.

[0005] Therefore, single-piece clamping leads to production rhythm interruptions, high labor intensity for manual clamping and positioning, and low equipment utilization due to frequent downtime and tool changes, resulting in increased parts processing costs. These problems constitute the technical bottleneck restricting the efficient and economical production of bow-shaped parts. Summary of the Invention

[0006] To address the problems existing in the background art, the present invention provides a tooling for batch processing of bow-shaped parts, comprising a base and several clamping bodies mounted vertically on the base. The base has an outer boss and an inner boss, both of which are annular structures. The inner boss is located inside the outer boss and is fixedly connected to it. The clamping bodies are hollow cylindrical structures. The inner side of the bottom of the clamping body has an inner boss for connecting with the base or adjacent clamping bodies. The inner side of the top of the clamping body has an inner boss for connecting with adjacent clamping bodies. The outer wall of the clamping body has an outer boss for mounting bow-shaped parts. Positioning pins are spaced apart on the upper side of the outer boss of the base and the upper side of the outer boss of the clamping bodies. Telescopic mechanisms are spaced apart on the lower side of the outer boss of the clamping bodies. Bow-shaped parts are mounted between adjacent positioning pins.

[0007] In the preferred embodiment, several telescopic mechanisms are installed on the lower side of the outer boss of the fixture at 60° central angle intervals.

[0008] In a preferred embodiment, the telescopic mechanism is a hydraulic cylinder, which is equipped with a telescopic rod for pressing the bow-shaped parts.

[0009] In the preferred embodiment, two layers of external clamping bosses are provided on the outer side of the clamping body.

[0010] In the preferred embodiment, a U-shaped groove for fixing the base is provided on the outer protrusion of the base.

[0011] In a preferred embodiment, the positioning pin includes a cylindrical pin and a diamond-shaped pin, with adjacent positioning pins being a cylindrical pin and a diamond-shaped pin, respectively.

[0012] In the preferred embodiment, the inner boss of the base and the inner boss of the clamp are provided with several mounting holes, and the base and the clamp body, as well as adjacent clamp bodies, are connected and fixed by inserting bolts into the mounting holes.

[0013] In the preferred embodiment, the uppermost clamping body has a lifting ring installed on the upper side of the inner boss of the clamp.

[0014] In the preferred embodiment, several reinforcing ribs are installed between the inner boss of the clamping fixture at the top of the clamping fixture and the inner boss of the clamping fixture at the bottom of the clamping fixture.

[0015] In the preferred embodiment, the reinforcing ribs are evenly spaced at 60° central angle intervals.

[0016] The beneficial effects achieved by this invention are as follows:

[0017] The tooling for batch processing of bow-shaped parts of this invention features a detachable connection between the base and multiple clamping bodies, supporting the installation of multiple clamping bodies and multiple bow-shaped parts. This reduces workpiece changeovers and non-production time, effectively improving equipment utilization and reducing wear and energy consumption caused by equipment start-ups and shutdowns. It effectively solves the problems of low efficiency, high labor intensity, low equipment utilization, and high processing costs in traditional processing methods, providing a new solution for the efficient and economical production of bow-shaped parts. Specifically:

[0018] First, the fixture body is a hollow cylindrical structure, which reduces the weight of the tooling. The top and bottom of the fixture body are connected by reinforcing ribs, which enhances the structural strength of the fixture. The reinforcing ribs are evenly distributed at a 60° central angle, which helps to distribute the load evenly, improve the overall structural stability, meet the requirements of supporting heavy loads or coping with harsh working conditions, and expand the scope of application.

[0019] Secondly, the installation of positioning pins on the outer protrusions of the base and the fixture enables automatic workpiece positioning, reducing manual operation and lowering labor intensity.

[0020] Third, hydraulic cylinders and other telescopic mechanisms are installed at intervals on the lower side of the outer boss of the fixture to realize automated clamping of bow-shaped parts and improve clamping efficiency.

[0021] Fourth, the two-layer fixture with external bosses can accommodate the installation of bow-shaped parts of different sizes or shapes, improving the adaptability of the tooling.

[0022] Fifth, the U-shaped groove on the outer protrusion of the base simplifies the base fixing process and improves the tooling installation efficiency.

[0023] Sixth, the alternating use of cylindrical pins and diamond pins improves positioning accuracy and stability.

[0024] Seventh, the mounting holes on the inner boss of the base and the inner boss of the fixture are matched with bolts to achieve quick and reliable connection and disassembly, which improves the efficiency of disassembly and assembly and reduces maintenance costs.

[0025] Eighth, the lifting rings on the top clamp facilitate the hoisting of tools and improve handling efficiency. Attached Figure Description

[0036] Reference Figures 1-7 A tooling for batch processing of bow-type parts includes a base 1 and several clamping bodies 2 installed on the base 1 in a vertical direction. The base 1 is provided with an outer boss 11 and an inner boss 12, which are annular structures. A U-shaped groove 111 for fixing the base 1 is provided on the outer boss 11.

[0037] An inner boss 12 is located inside the outer boss 11 of the base and is fixedly connected to it. The clamping body 2 is a hollow cylindrical structure. An inner boss 22 for connecting with the base 1 and adjacent clamping bodies 2 is provided on the inner side of the bottom of the clamping body 2. An inner boss 22 for connecting with adjacent clamping bodies 2 is provided on the inner side of the top of the clamping body 2. A number of reinforcing ribs 23 are installed between the inner boss 22 on the top of the clamping body 2 and the inner boss 22 on the bottom of the clamping body 2. The reinforcing ribs 23 are preferably evenly arranged at 60° central angle intervals.

[0038] The outer wall of the clamp body 2 is provided with a clamping outer boss 21 for mounting bow-shaped parts 6. Preferably, two layers of clamping outer bosses 21 are provided on the outer side of the clamp body 2. Several mounting holes 4 are provided on the inner boss 12 of the base and the inner boss 22 of the clamp. The base 1 and the clamp body 2, and adjacent clamp bodies 2 are connected and fixed by inserting bolts 7 into the mounting holes 4.

[0039] Positioning pins 3 are installed at intervals on the upper side of the outer boss 11 of the base and the upper side of the outer boss 21 of the clamp; the positioning pins 3 preferably include columnar pins 31 and rhomboid pins 32, and adjacent positioning pins 3 are columnar pins 31 and rhomboid pins 32 respectively. Telescopic mechanisms 5 are installed at intervals on the lower side of the outer boss 21 of the clamp; bow-shaped parts 6 are installed between adjacent positioning pins 3.

[0040] Several telescopic mechanisms 5 are installed on the lower side of the outer boss 21 of the fixture at 60° central angle intervals. The telescopic mechanism 5 can be a hydraulic cylinder, which is equipped with a telescopic rod for pressing the bow-shaped part 6.

[0041] To facilitate the movement and transportation of the entire tooling, the uppermost clamping fixture 2 has a lifting ring 8 installed on the upper side of the inner boss 22.

[0042] Example 1

[0043] In this embodiment, the machining fixture 2 consists of a base 1 and two fixture bodies 2 connected by bolts 7. The two fixture bodies 2 have four layers of external bosses 21, which, together with the external bosses 11 of the base, form a total of five layers of bosses constituting a positioning reference surface. Each positioning reference surface is equipped with three sets of cylindrical pins 31 and rhomboid pins 32. A hydraulic cylinder seat is correspondingly installed above the cylindrical pins 31 and rhomboid pins 32, and the hydraulic cylinder is mounted on the hydraulic cylinder seat. Each set of cylindrical pins 31 and rhomboid pins 32, together with its corresponding hydraulic cylinder, constitutes a positioning and clamping station for a bow-shaped part 6. The hydraulic control system is installed in the space inside the fixture body 2. The hydraulic control system is communicatively connected to all hydraulic cylinders, controlling the extension rod of each hydraulic cylinder to press and release the bow-shaped part 6.

[0044] During workpiece clamping, the hydraulic control system retracts the extension rod of the hydraulic cylinder, sequentially aligning the mounting holes 4 of the bow-plate type part 6 with a set of cylindrical pins 31 and diamond pins 32, thus positioning the bow-plate type part 6 on the positioning reference surface. After all bow-plate type parts 6 are positioned according to the positioning requirements, the hydraulic control system extends the extension rod of the hydraulic cylinder to clamp the lower bow-plate type part 6, ensuring accurate positioning and secure clamping of all workpieces. After all bow-plate type parts 6 in a set have been machined, the hydraulic control system retracts the extension rod of the hydraulic cylinder to remove the finished bow-plate type part 6.

[0045] Repeat the above operations to start a new round of processing. When it is necessary to move the tooling, install a lifting rope inside the lifting ring 8 and connect the lifting rope to the crane to lift and move the tooling.
