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.

Abstract

The invention discloses a clamping fixture for a hollow part, which comprises a fixed plate, a chuck, a jaw unit, a centering support column and a top unit, and the flower groove is provided with more than three notches. Use the fixed plate to clamp and fix it on the main shaft of the lathe, and set the hollow workpiece on the chuck, so the worm rod can be driven to move along the top shaft hole through the worm handle. Then, the centering support column hinged on the fixed convex ring is supported and opened by the support rod, that is, the centering support column rotates around the fixed convex ring through the push of the support rod, and then the centering support column is opened to support the hollow workpiece. To achieve the purpose of pre-fixing hollow workpieces. Then start the lathe, make the chuck follow the high-speed rotation of the lathe spindle, make the jaw unit generate centrifugal force, then contact and fix the inner wall of the hollow workpiece, and further clamp the workpiece, and the multi-point clamping can ensure the hollow The coaxiality of similar parts can achieve the purpose of improving processing efficiency.

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.
