Embodiment

[0042] The embodiment is basically as attached Figure 1 to Figure 12 As shown, a pressing mechanism includes a positioning block and a pressing plate 1. The positioning block includes a positioning column 2 and a mounting seat 3. The positioning column 2 is cylindrical, and the free end of the positioning column 2 is processed with an arc-shaped guide surface. The positioning column 2 is lower than the hardness of the workpiece 10, so as to facilitate the insertion of the workpiece 10 into the positioning column 2 and ensure that the positioning column 2 will not damage the design hole of the workpiece 10 during the insertion of the workpiece 10. For example, the positioning column 2 of this embodiment is made of nylon material. The workpiece 10 is made of metal.

[0043] The mounting seat 3 includes an integrally formed support pier 31 and a support arch 32. The positioning column 2 is fixedly connected to the support arch 32 by bolts. The support pier 31 is in an inverted T...

Abstract

The invention relates to the technical field of machining, and particularly discloses a pressing mechanism which comprises a positioning block and a pressing plate, the pressing plate is rotationally connected to the positioning block, a trigger section and a hook-shaped section which are fixedly connected are arranged on the two sides of the rotating center of the pressing plate, the trigger section is located on the section close to the fixed end of the positioning block, and the hook-shaped section is located on the section close to the free end of the positioning block. A receding groove used for containing the hook-shaped section is formed in the positioning block, and after the trigger section rotates, the hook-shaped section of the pressing plate can stretch out of the receding groove to be pressed on the surface of the workpiece. According to the scheme, the problems that in the prior art, due to high-difficulty pressing and clamping of a workpiece in machining, a cutter is vibrated, or machining efficiency is low, machining cost is high, machining quality is unstable or the machining quality cannot meet the requirement are solved.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a pressing mechanism. Background technique [0002] In the machining of the workpiece, in order to ensure stable and high-quality processing during the processing, the workpiece is generally supported and pressed (also called the clamping of the workpiece). Positioning, supporting and pressing are easy to realize. For example, setting the positioning block directly on the fixture of the machine tool, and inserting the positioning block directly into the designed hole of the workpiece to complete the positioning of the workpiece; setting the supporting component, from the workpiece One side (such as the bottom surface of the workpiece) is supported, and then a pressure plate for pressing the workpiece is set on the other side of the workpiece (such as the top surface of the workpiece). In order to facilitate the installation of the pressure plate, the pressure plate needs to be ...
