Description
Technical Field
[0001] The utility model relates to the field of nozzles, in particular to a device for punching holes in a long-necked nozzle with a diameter-distance pressure measurement. Background Art
[0002] In the prior art, a fixture refers to a device used to fix the processing object in the mechanical manufacturing process so that it occupies the correct position to accept construction or inspection, also known as a fixture. In a broad sense, any device used to quickly, conveniently and safely install the workpiece in any process in the process can be called a fixture. A fixture usually consists of a positioning element (to determine the correct position of the workpiece in the fixture), a clamping device, a tool guide element (to determine the relative position of the tool and the workpiece or to guide the direction of the tool), a dividing device (to enable the workpiece to complete the processing of several stations in one installation, and there are two types: a rotary dividing device and a linear moving dividing device), a connecting element, and a clamp body (fixture base). The types of fixtures can be divided into the following according to their usage characteristics: ① Universal general fixtures. ② Special fixtures. ③ Adjustable fixtures. ④ Combination fixtures. When the auxiliary nozzle seat is punched at the bottom, it cannot be fixed on the drilling and tapping machining center or lathe. Clamping with a three-jaw chuck or soft jaws will damage the surface of the part, and the clamping will not be firm. It will deviate or fly out during machining, which is dangerous during processing. In addition, the angle is difficult to adjust and the processing efficiency is low. It can be seen that the current fixture is difficult to ensure that the side wall of the nozzle will not be clamped and damaged while having a good clamping effect, and the fixture is difficult to adapt to nozzles of various sizes.
