Problems solved by technology
The clamps in the prior art are complicated to adjust during use, especially when drilling holes for different types of workpieces, especially for special-shaped workpieces with circumferential surfaces, ordinary clamps cannot meet the corresponding clamping force, and looseness is prone to occur during processing This in turn leads to deviations in the drilling accuracy of the workpiece, resulting in an increase in the scrap rate of the workpiece blank

The invention discloses a special-shaped workpiece clamping structure capable of realizing two-stage fastening. The special-shaped workpiece clamping structure comprises a base and a fastening block, wherein a clamping seat is arranged on the upper surface of the base, a connecting rod is arranged on one side of the base, an internal threaded hole is formed in the other side of the base, the lower end of a guide rod is arranged in the internal threaded hole and in thread fit with the internal threaded hole, a universal ball head is arranged at one end of the fastening block, the upper end of the guide rod is connected with the universal ball head, a screw hole is formed in the other end of the fastening block, a screw movably penetrates the screw hole, and the lower end of the screw is connected with the upper end of the connecting rod through a rotary connector; the special-shaped workpiece clamping structure further comprises a push rod which movably penetrates the middle of the fastening block, and a movable block right facing the clamping seat is mounted at an end part of the push rod. When a workpiece blank produces larger vibration due to drilling, the stability of a workpiece is guaranteed through primary fastening of the workpiece by the movable block and secondary fastening realized by the fastening block, the guide rod, a connecting assembly and the base, and workpiece machining precision is improved.
Description
technical field [0001] The invention relates to the field of machining, in particular to a special-shaped workpiece clamping structure capable of realizing secondary fastening. Background technique [0002] The device used to fix the processing object in the process of mechanical manufacturing so that it occupies the correct position to accept construction or inspection, also known as fixture. In a broad sense, any process in the process, the device used to install the workpiece quickly, conveniently and safely, can be called a fixture. Such as welding fixtures, inspection fixtures, assembly fixtures, machine tool fixtures, etc. Among them, machine tool fixtures are the most common, often referred to as fixtures. When processing a workpiece on a machine tool, in order to make the surface of the workpiece meet the technical requirements such as the size, geometric shape, and mutual position accuracy with other surfaces specified in the drawing, the workpiece must be install...
