Description

Technical Field

[0001] This utility model relates to the field of machining tooling technology, specifically to a front bearing housing machining tooling. Background Technology

[0002] In the field of machining, bearing housings are key components that support and fix bearings, and their machining accuracy and efficiency directly affect the assembly quality and performance of equipment. Traditional bearing housing machining usually adopts a single-piece clamping and sequential machining method, which is not only time-consuming for tool setting and positioning, but also makes it difficult to guarantee machining consistency. Especially in mass production, the production efficiency is low and it is difficult to meet the needs of modern manufacturing.

[0003] In the existing technology, although some tooling designs are used for simultaneous processing of multiple workpieces, the following shortcomings still exist: First, most tooling can only fix the workpiece on one side, and after processing, it needs to be disassembled and clamped again, which is cumbersome; second, there is a lack of efficient flipping structure, which cannot make full use of the machine tool's processing stroke, resulting in low equipment utilization; third, the tooling lacks versatility and stability, making it difficult to adapt to the processing needs of bearing seats of different specifications.

[0004] Therefore, there is an urgent need for a new type of bearing housing machining fixture that can fix multiple workpieces side by side and complete batch processing in a single tool setting. Furthermore, the fixture's double-sided clamping and flipping functions further reduce clamping time and improve processing efficiency and accuracy. This technical solution optimizes the fixture structure by setting clamping handles at both ends to achieve rapid switching between the front and back sides, providing a reliable solution for efficient batch processing of bearing housings. Utility Model Content

[0005] This utility model provides a front bearing housing machining fixture, which improves clamping stability and machining accuracy, reduces repeated positioning errors, and facilitates quick installation and flipping of the fixture, thereby improving machining efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a front bearing housing machining fixture, comprising: a main body, the top of which has a horizontal upper reference surface and a plurality of mounting screw holes, and horizontally extending clamping columns coaxially at opposite ends of the main body; a clamping seat, which is disposed on the top of the upper reference surface and has through mounting bolts that engage with the mounting screw holes, the top of the clamping seat having a positioning platform adapted to the bottom of the workpiece, and a clamping screw hole at the center of the top of the positioning platform; and a pressure plate, which is disposed above the positioning platform and has through clamping bolts that engage with the clamping screw holes.

[0007] Preferably, the bottom of the main body is provided with a lower reference surface parallel to the upper reference surface, and each of the mounting screw holes penetrates the main body; the clamping seats are arranged in pairs and symmetrically installed on the top and bottom of the main body.

[0008] Preferably, the clamping seat has a pin hole on one side corresponding to the positioning table, and a positioning pin that mates with the workpiece is provided in the pin hole.

[0009] Preferably, the bottom of the pressure plate is provided with a positioning post that is adapted to the top of the workpiece.

[0010] Preferably, the mounting bolts are distributed around the positioning platform and do not overlap with the workpiece.

[0011] The beneficial effects of this utility model are as follows: The upper reference surface of the main body provides a horizontal installation reference, ensuring the positioning accuracy of the clamping seat and the workpiece. The mounting screw holes are used to fix the clamping seat, making it detachable and adjustable to adapt to workpieces of different specifications. The positioning table matches the bottom shape of the workpiece, providing precise positioning and preventing displacement during processing. The pressure plate, in cooperation with the clamping bolts and clamping screw holes, presses the workpiece downwards to prevent loosening during processing, ensuring accurate workpiece positioning, reducing clamping errors, improving rigidity during processing, and avoiding quality problems caused by vibration. Clamping columns are set at both ends of the main body for clamping by machine tools or fixtures, allowing the fixture to be flipped to adjust the processing angle. This fixture, through modular design and multiple positioning methods, reduces clamping errors, ensures processing consistency, clamps multiple workpieces at once, reduces tool change and adjustment time, is suitable for batch production scenarios, and can significantly improve the processing efficiency and quality of bearing seats. The lower reference surface is parallel to the upper reference surface, allowing the fixture to be flipped for use, fixing the workpiece on both sides, and achieving symmetrical arrangement. Therefore, more workpieces can be processed in one clamping, reducing changeover time and improving processing efficiency. The locating pin engages with the locating hole on the bottom of the workpiece to provide circumferential angular positioning, preventing workpiece rotation or displacement, enhancing workpiece stability under cutting forces, and improving machining accuracy. The locating post embeds into the hole or groove on the top of the workpiece to provide auxiliary positioning, thereby enhancing positioning accuracy, ensuring the workpiece does not shift during machining, improving machining consistency and clamping accuracy, and preventing workpiece displacement during clamping. The mounting bolts avoid interference with the workpiece, ensuring sufficient clamping space, while also facilitating workpiece loading and unloading, improving clamping efficiency.
