Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy forging processing technology, specifically a sandblasting fixture for aluminum alloy forgings. Background Technology

[0002] Aluminum alloys are widely used in the aerospace industry. The production of aluminum alloy products generally includes several processes: smelting, casting, homogenization annealing, extrusion, quenching, and artificial aging treatment. Currently, after heat treatment, aluminum alloy forgings are prone to surface defects such as discoloration, scratches, dents, and burrs, which require sandblasting to resolve.

[0003] In the prior art, the authorized patent with publication number CN203945268U discloses a tooling structure for sandblasting aluminum alloy forgings, including a central rod. Multiple hanging plate assemblies are mounted on the central rod. Each hanging plate assembly consists of an outer ring plate and an inner ring plate. One end of multiple reinforcing ribs is connected to the outer periphery of the central rod, and the other end of each reinforcing rib passes through the inner ring plate and connects to the inner periphery of the outer ring plate. Multiple hooks for suspending aluminum alloy forgings are fixed to the outer and inner ring plates by fasteners. This invention has a simple structure and is easy to operate. It allows for the quick and convenient suspension of aluminum alloy forgings, preventing damage during sandblasting and ensuring complete coverage. This not only effectively achieves uniform sandblasting of the aluminum alloy forgings and improves sandblasting efficiency but also enables large-scale sandblasting of aluminum alloy forgings. Furthermore, the outer ring plate, inner ring plate, and hooks in the hanging plate assembly are easy to assemble and disassemble, and their quantity can be increased or decreased according to production needs.

[0004] However, the above technical solution still has the following shortcomings when in use: the above device cannot adjust the upper and lower spacing of the ring plates according to the size of the aluminum alloy forging, which means that when the size of the aluminum alloy forging to be sandblasted is small, it is impossible to place multiple ring plates on the central rod to hook more aluminum alloy forgings, which reduces the sandblasting efficiency and has poor practicality. In this regard, we propose a sandblasting fixture for aluminum alloy forgings to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a sandblasting fixture for aluminum alloy forgings to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sandblasting fixture for aluminum alloy forgings, comprising:

[0007] A central rod has a stop block fixedly welded to its bottom end. The central rod is equipped with multiple hook assemblies, each including a mounting sleeve fitted onto the central rod. Multiple annularly distributed connecting rods are fixedly welded to the mounting sleeve, and the outer ends of the multiple connecting rods are fixedly welded to the same ring plate. Multiple hooks are fixedly installed on the ring plate. A bent hook is provided at the top of the central rod. Multiple equally distributed threaded grooves are formed on the outer wall of the central rod. Locking studs are threadedly connected to the mounting sleeve through threaded holes, and the locking studs are threaded into the threaded grooves.

[0008] Preferably, two positioning sliders are fixedly welded to the inner wall of the mounting sleeve, and two positioning grooves are formed on the outer wall of the central rod, with the positioning sliders matching the positioning grooves.

[0009] Preferably, the top end of the central rod is provided with a threaded hole, and the bottom end of the hook is fixedly welded with a screw, which is threaded into the threaded hole.

[0010] Preferably, a turning wheel is fixedly installed on the outer end of the locking stud.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In use, this invention allows for the installation of multiple hook assemblies on the central rod. These hook assemblies, through the cooperation of mounting sleeves, locking studs, and threaded grooves, can be installed at different positions on the central rod. This allows for the adjustment of the spacing between multiple hook assemblies when the aluminum alloy forging is small, enabling the installation of more hook assemblies on the central rod. This, in turn, allows for the hooking of a larger number of aluminum alloy forgings for sandblasting, improving the sandblasting efficiency and enhancing practicality. Attached Figure Description
