Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing and relates to a drilling machine clamp. Background Art

[0002] In the field of modern mechanical processing, drilling machines, as an important metal cutting tool, are widely used in the manufacturing process of various parts.

[0003] A drill press fixture is a device specifically designed to secure a workpiece to the drill press. It not only ensures workpiece stability and accuracy during machining, but also significantly improves work efficiency and reduces defective product rates caused by workpiece movement. Depending on the application scenario and workpiece characteristics, various types of drill press fixtures are available on the market, including general-purpose vises and specialized fixtures. Among them, vises are the most common choice due to their simple structure and ease of operation.

[0004] However, in practice, traditional vises often struggle to meet the demands for efficient and precise fixturing when faced with variable and irregular mold shapes. Due to the often complex design of molds, their surfaces may include uneven surfaces or unusual geometric shapes, making it difficult for conventional vises to achieve comprehensive and effective contact and fixation. Furthermore, while other clamping methods can address these issues to a certain extent, they often come with more complex operational processes, increasing worker workload and potentially extending production cycles, impacting overall production efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide a drilling machine clamp that can be used for clamping and fixing workpieces of different shapes, is suitable for fixing during mold production and processing, and is convenient to fix and simple to operate, thereby helping to improve overall production efficiency.

[0006] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion. The outer sleeve is provided with a rotating connecting sleeve rotatably connected to it, the lower pressure plate and the elastic member are both arranged in the rotating connecting sleeve, the internal rotation connection of the upper end of the rotating connecting sleeve is provided with a rotating shaft rotating in a vertical plane, the outer side of the rotating shaft is provided with an extrusion protrusion that can squeeze the lower pressure plate downward, both ends of the rotating shaft extend out of the rotating connecting sleeve and are provided with eccentric fan-shaped extrusion blocks, the middle part of the rotating shaft is provided with a connecting plug shaft outward at the middle position between the extrusion protrusion and the eccentric fan-shaped extrusion block, the arc edge of each eccentric fan-shaped extrusion block is toward the connecting plug shaft, and the distance between it and the rotating shaft gradually increases.

[0007] By adopting the above technical solution, when it is necessary to clamp and fix the mold, first place the mold on the workbench, connect it to the connecting shaft with a sleeve, and then press the sleeve downward to rotate the rotating shaft downward, driving the extrusion protrusion to squeeze the lower pressure plate downward to compress the elastic rubber pad, so that the extrusion plate is separated from the lower end of the workbench. At this time, the slider can be slid at will so that each eccentric sector-shaped extrusion block is close to the side wall of the workpiece, and then the rotating shaft is rotated to reset so that the extrusion protrusion no longer squeezes the lower pressure plate, and the extrusion plate contacts the lower end of the workbench again to limit the sliding of the slider, and finally insert the sleeve into the upper table to rotate the rotating shaft upward to drive the eccentric sector-shaped extrusion block to rotate toward the workpiece, gradually squeezing and clamping the workpiece, locking and fixing the workpiece, and then drilling operations can be carried out.

[0008] The utility model is further configured such that a connecting platform is provided at the upper end of the clamping seat, the elastic member is located at the upper end of the connecting platform, and a connecting ring is provided inwardly at the lower end of the rotating connecting sleeve to match the lower end of the connecting platform.

[0009] The present invention is further configured such that the elastic member is an elastic rubber pad, and a through hole matching the sliding shaft is provided in the middle of the elastic rubber pad.

[0010] The present invention is further configured such that the upper end of the rotating connecting sleeve is open, and two opposite sides of the upper end of the rotating connecting sleeve are provided with rotating rings rotatably connected to the rotating shaft.

[0011] The utility model is further configured such that an arc-shaped extrusion sheet is connected between the arc-shaped edges of the two opposite eccentric sector-shaped extrusion blocks.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] First, the clamping member on the drilling machine fixture of the utility model can slide freely along the slide rail groove, which can better adapt to molds of different shapes and sizes, especially for those with complex geometric shapes or irregular surfaces, and can provide more stable and reliable fixation, thereby improving the stability and precision during the processing;

[0014] Secondly, by optimizing the design of the fixture, the position of the slider can be freely moved by simply pressing downward, and the eccentric fan-shaped extrusion block can be squeezed and clamped to hold the workpiece by moving upward, which simplifies the clamping process and reduces the time required to adjust and fix the workpiece. This not only reduces the workload of the operator, but also speeds up the production rhythm, helping to improve overall production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
