The invention provides a stress-free fixing device based on a freezing disc. The fixing device comprises a box body, a quick refrigerating device and the freezing disc; a cooling network is arranged on the cooling surface of the freezing disc, and the plurality of first grooves and the plurality of second grooves of the cooling network are communicated with each other, so that cold air directly sprayed on the cooling surface by the quick refrigerating device can quickly cover the freezing disc, and the efficiency of taking away heat is improved; and meanwhile, the freezing fixing effect of thefreezing disc is ensured; cobweb type stable stripes are arranged on the fixing face of the freezing disc, the friction force between a workpiece and the fixing face is increased, meanwhile, the influence of molten water on the workpiece can be weakened through the circumferential grooves and the radial grooves, and the stability of the workpiece on the freezing disc is guaranteed. The stress-free fixing device is reasonable in structural design, and the machining efficiency and the machining quality of the workpiece are effectively guaranteed.
Description
technical field [0001] The invention relates to the technical field of clamps for machining, in particular to a stress-free fixing device based on a freezing tray. Background technique [0002] In machining, a fixture is a device on a machine tool for clamping a workpiece (and guiding a tool). Its function is to position the workpiece so that the workpiece can obtain the correct position relative to the machine tool and the tool, and clamp the workpiece reliably. . However, in the application of traditional fixtures, for special parts, there must be special fixtures to adapt to them, which lacks wide applicability; for thin-walled materials, traditional fixtures are easy to cause damage to the material itself; for special precision processing, traditional The precision of the fixture is not high, and the manufacturing cycle is too long. [0003] Compared with the traditional fixing methods such as clamping, magnetic chuck, vacuum chuck, etc., the freezing plate utilizes th...
