Abstract
The utility model discloses a mandrel processing auxiliary device. The mandrel processing auxiliary device is characterized by comprising a metal cylinder and locating screws which are radially and uniformly distributed on the wall at the two ends of the metal cylinder, wherein the inner diameter of the metal cylinder is matched with the outer diameter of a mandrel, and the middle part of the outer surface at the periphery of the metal cylinder is recessed to form an annular groove. The mandrel processing auxiliary device disclosed by the utility model can locate the mandrel with larger diameter and can be used by combining with a center frame, no new center frame is required to be manufactured, production requirement can be met, and production cost is reduced.
Description
Technical field
The utility model relates to a kind of mach frock clamp, particularly a kind of plug auxiliary processing device.
Background technology
Need use card jar centering turning shelf mouth when plug is rough turn, also use the card jar when borrowing bending during finish turning.Produce at present and use a card jar profile to be cylindrical shape, its internal diameter size designs and produces according to the diameter dimension of processing plug, and general card jar needs centre frame to support; When the diameter of mandrel of processing is bigger; The card jar cylindrical that designs and produces according to conventional method is bigger, can not with the supporting use of centre frame, need again the design centre frame to satisfy production requirement; Because it is higher to make the expense of centre frame, therefore increased production cost.
Summary of the invention
The utility model provides a kind of secondary process device that can adaptive centre frame can locate the bigger plug of diameter for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of plug auxiliary processing device; Comprise that metallic cylinder reaches the dog screw of radial equipartition on the barrel of metallic cylinder two ends; Said metallic cylinder internal diameter and plug external diameter are complementary, and said metallic cylinder circumferential outer surface middle part is recessed to be annular groove.
The utility model can also adopt following technical scheme:
Said annular groove groove depth is 20～50mm.
Said annular groove width is 1/2～2/3 of a said metallic cylinder length overall.
Advantage and the good effect that the utlity model has are: when the diameter of mandrel of processing is bigger; Recessed cylindrical shape plug location, middle part secondary process device, still can with the supporting use of centre frame, need not to make new centre frame; Can satisfy production requirement, reduce production cost.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure: 1, metallic cylinder, 2, the annular groove at metallic cylinder circle middle part, 3, the screwed hole of assembling and positioning screw.
The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1; A kind of plug auxiliary processing device; Comprise that metallic cylinder 1 reaches the dog screw of radial equipartition on the barrel of metallic cylinder two ends; The screwed hole 3 of assembling and positioning screw radial equipartition on the barrel of metallic cylinder 1, said metallic cylinder internal diameter and plug external diameter are complementary, and said metallic cylinder circumferential outer surface middle part is recessed to be annular groove 2.
Said annular groove 2 groove depths can be 20～50mm, and said annular groove 2 width can be 1/2～2/3 of cylinder length overall.
The operation principle of the utility model: on the basis of original cylindric card jar structure; Make cylindrical into middle part recessed stairstepping; Its metallic cylinder middle part contacts with the centre frame strong point; Under the prerequisite of proof strength, reduce the thickness of contact site as far as possible, itself and existing centre frame can be used.
