Description

Technical Field

[0001] The present invention relates to the technical field of mechanical processing equipment, and in particular to an adjustable positioning and clamping device suitable for use in the processing of small precision workpieces, and more particularly to a small workpiece clamping system with a dual-axis angle adjustment function. Background Art

[0002] In the field of micro-precision machining and small structural parts assembly, workpieces are usually small in size and complex in shape, which places higher demands on the clamping stability, positioning accuracy and adjustment flexibility of the fixture. Traditional methods for clamping small workpieces mainly rely on fixed brackets and one-way locking mechanisms, and complete the rough positioning of the workpiece through manual adjustment. However, this type of traditional fixture has many shortcomings: first, the positioning angle is fixed and the adjustment means are limited, which makes it difficult to meet the processing and assembly requirements of complex workpieces in multiple degrees of freedom in space; second, the clamping force is unevenly distributed, which can easily cause small workpieces to deform or loosen due to force, affecting the subsequent processing accuracy; third, existing fixtures usually require the disassembly of multiple components during the changeover process, and the adjustment steps are cumbersome, which seriously restricts the improvement of production efficiency. Especially in the context of the increasing popularity of intelligent manufacturing and micro-assembly systems, product iteration cycles are shortened, and small-batch, multi-variety production models have put forward higher standards for the flexibility and rapid adjustment capabilities of fixtures. While some fixtures have achieved single-axis angle adjustment by adding indexing plates and rotatable bases, solutions that can flexibly adjust in both directions while maintaining high positioning accuracy are still relatively scarce. Furthermore, these fixtures are complex and bulky, making them unsuitable for high-precision machining and assembly of small workpieces. Therefore, there is an urgent need to develop a compact, reliable, and dual-axis adjustable small workpiece fixture that can achieve efficient, precise, and flexible workpiece positioning and clamping operations, meeting the new demands placed on clamping equipment by modern micro-manufacturing processes.

[0003] In order to solve the above problems, the technical solution of the present invention is as follows: A small workpiece clamping device with a dual-axis adjustable function, including a base, a rotating seat, a support column, and a clamping assembly, characterized in that: the support column is vertically installed on the top surface of the base; the rotating seat is rotatably installed on the upper end of the support column, and a fastening device is provided on the rotating part; a rotating screw is provided on the top of the rotating seat, and a mounting plate is provided at one end of the clamping assembly, and a threaded hole A is provided on the mounting plate, which is installed on the rotating screw through threaded cooperation, and a locking nut is provided on the rotating screw for fastening the clamping assembly.

[0004] A plurality of mounting screw holes A are evenly spaced along the four edges of the support column, and a plurality of mounting screw holes B are correspondingly provided on the base. The support column is fixed to the base by screwing screws into the mounting screw holes A and their corresponding mounting screw holes B.

[0005] A horizontal screw is provided on the upper end of the supporting column, and the rotating seat is installed at both ends of the horizontal screw through the hanging ear and the screw hole on the hanging ear, and can rotate relative to the horizontal screw. The fastening device is a fastening nut; fastening nuts are respectively provided at both ends of the horizontal screw; by tightening the fastening nut, the hanging ear and the horizontal screw are fastened, thereby fixing the rotating seat so that it cannot rotate.

[0006] A threaded hole B is provided on the top of the rotating seat, and the rotating screw is screwed into the threaded hole A and the threaded hole B. The rotating seat can rotate based on the rotating screw. The end of the rotating screw is fastened together with the clamping assembly by screwing a nut, so that the rotating screw cannot rotate.

[0007] The clamping assembly includes a base plate, a clamping side plate, and a clamping bolt, which is provided with a plurality of threaded holes of different sizes and shapes, and is manually tightened by a knob or an Allen wrench.

[0008] The supporting columns are in a square column or cylindrical structure.

[0009] The height of the support column is 80mm±5mm.

[0010] The beneficial effects of the present invention are: First, through manual adjustment of the rotating component and the locking bolt, small workpieces can be quickly adjusted to the optimal processing posture during processing, assembly and other operations, avoiding multiple disassembly and positioning, and improving work efficiency; secondly, the clamping component has a simple structure, convenient operation, and easy disassembly and assembly, which shortens the changeover and adjustment time and meets the requirements of high-frequency and multi-change operations; thirdly, the modular structural design enhances the versatility and maintainability of the device, while reducing production costs and improving the service life and economy; finally, the overall layout of the present invention is compact and occupies a small space, which is particularly suitable for desktop precision processing, micro tooling systems and educational and scientific research platforms.
