Embodiment Construction
[0040] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.
[0041] see Figure 1 to Figure 7 , this embodiment provides a clamping fixture for hollow parts, such as figure 2 As shown, including the fixed disc 10, the chuck 20, the jaw unit 30, the centering support column 40 and the tip unit 50, the diameter of the inner hole of the hollow part must be greater than 60mm at least, and the centering support column in this embodiment can clamp The inner hole diameter of the hollow part 1 is between 100mm and 220mm, and the hollow part larger than 220mm can be clamped by changing the size of the centering support column. A connecting shaft 60 is arranged between the fixed disk and the chuck, and a flower groove 21 and a fixing convex ring 22 are arranged on the end surface of the chuck.

The invention discloses a hollow part inner clamping clamp. The hollow part inner clamping clamp comprises a fixing disc, a chuck, a clamping jaw unit, centering supporting columns and a center unit,and a spline groove is provided with three or more notches. The fixing disc is clamped and fixed on a spindle of a lathe, a hollow workpiece sleeves the chuck, therefore, a worm can be driven to movealong a center axis hole through a worm wheel handle, then the centering supporting columns hinged to a fixing convex ring are supported and opened through a supporting rod, namely, the centering supporting columns rotate around the fixing convex ring through pushing by the supporting rod, then the centering supporting columns are expanded so as to support the hollow workpiece, so that the purposeof pre-fixing the hollow workpiece is achieved, then the lathe is started to enable the chuck to rotate at a high speed along with the lathe spindle, so that the clamping jaw unit generates centrifugal force and then makes contact with the inner side wall of the hollow workpiece for fixation, so that the workpiece is further clamped, moreover, the coaxiality of the hollow part can be ensured through multi-point-position clamping, and the purpose of improving the machining efficiency is achieved.
Description
technical field [0001] The invention relates to the field of lathe clamps, in particular to an internal clamping clamp for hollow parts. Background technique [0002] In the existing lathes, most of the clamping of parts or workpieces is processed by external clamping, so the clamping part cannot be processed synchronously, so this part needs to be cut off or further repeated processing . For hollow parts, the machining allowance is less, so the processing technology requirements are higher, so as to meet the smoothness and coaxiality of the surface processing. Therefore, it is necessary to reduce or avoid repeated processing to eliminate manual errors and mechanical errors of multiple clamping. Improve production efficiency and production quality. Contents of the invention [0003] Therefore, it is necessary to provide an inner clamping fixture for hollow parts to solve the problems of low processing precision and high production cost of existing hollow parts.
