More existing products to be processed are cylindrical component, and material is steel forgings, and its inside is provided with through hole and locating hole, and this type of part processing and loading clamp comparatively bothers, and alignment time is long, and clamping is unstable, thus cause processing work of poor quality, production efficiency is low.
Utility model content
The utility model provides a kind of positioning tool for the product of the above-mentioned type, can ensure product to be processed can fast, accurate clamping, improve clamping stability, thus improve crudy and the production efficiency of workpiece.
The technical solution of the utility model is: comprise positioning disk, studs, pressing plate, nut, alignment pin, described positioning disk central authorities are provided with tapped through hole, edge is provided with multiple clear opening, described positioning disk upper surface is provided with positioning spigot, positioning spigot upper surface is provided with eccentric pin hole, and described alignment pin is located in dowel hole; Described pressing plate is provided with through hole, and described studs lower end is located in the tapped through hole of positioning disk, and upper end is connected with nut screw connection through pressing plate through hole.
As preferably, the clear opening on described positioning disk is circumferentially uniformly distributed.
As preferably, the external diameter of the positioning spigot on described positioning disk is less than or equal to product lower surface to be processed central aperture.
As preferably, the dowel hole on described positioning disk is just relative with the locating hole of product lower surface to be processed, and alignment pin upper end diameter is less than the internal diameter of the locating hole just relative with alignment pin.
As preferably, the through hole on described pressing plate is made up of elongated hole and the circular hole of being located at elongated hole one end, and elongated hole is communicated with circular hole, and elongated hole is positioned at pressing plate central authorities, and the width of elongated hole is less than nut external diameter, and Circularhole diameter is greater than nut external diameter.
As preferably, described pressing plate lower surface is provided with positioning spigot, and described positioning spigot external diameter is less than the central aperture of product upper surface to be processed.
The beneficial effects of the utility model are: this positioning tool is applicable to boring and milling and cuts etc. in machining, and production efficiency and product quality are all greatly enhanced.Can realize quick position, to workpiece quick despatch, simple, convenient and practical, the accurate positioning of this positioning tool structure simultaneously, fast-holding, result of use is good.

Detailed description of the invention
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
As Figure 2-3, the structure of the present embodiment comprises positioning disk 5, studs 9, pressing plate 10, nut 11, alignment pin 8, positioning disk 5 central authorities are provided with tapped through hole 13, edge is provided with multiple clear opening 6 circumferentially dividing equally distribution, positioning disk 5 upper surface is provided with positioning spigot 7, positioning spigot 7 upper surface is provided with eccentric pin hole 14, and alignment pin 8 is located in dowel hole 14; Pressing plate 10 is provided with through hole 17, and studs 9 lower end is located in the tapped through hole 13 of positioning disk, and upper end is connected through pressing plate through hole 17 and nut 11.
In the present embodiment, the external diameter of the positioning spigot 7 on positioning disk 5 is less than or equal to the aperture of product 1 lower surface to be processed medium pore 3.
In the present embodiment, the dowel hole 14 on positioning disk 5 is just relative with the locating hole 2 of product 1 lower surface to be processed, and alignment pin 8 upper end diameter is less than the internal diameter of the locating hole 2 just relative with alignment pin.
In the present embodiment, the through hole on pressing plate 10 is made up of elongated hole 16 and the circular hole 15 being located at elongated hole 16 one end, and elongated hole 16 is communicated with circular hole 15, and elongated hole 16 is positioned at pressing plate 10 central authorities, and the width of elongated hole 16 is less than nut 11 external diameter, and circular hole 15 diameter is greater than nut 11 external diameter.
In the present embodiment, pressing plate 10 lower surface is provided with positioning spigot 12, and positioning spigot 12 external diameter is less than the aperture of the medium pore 4 of product upper surface to be processed.
The positioning principle of this positioning tool is:
As shown in figs. 1 and 4, product lower end to be processed face coordinates with the positioning spigot on positioning disk, ensure that alignment pin upper end is placed in a locating hole of product lower surface to be processed simultaneously, pressing plate is placed in workpiece to be processed upper surface, upper surface medium pore coordinates with the positioning spigot of pressing plate lower surface, then fastening nut, and product to be processed is compressed by positioning disk and pressing plate, coordinate the effect of alignment pin simultaneously, product to be processed is located.
When needing dismounting after machining, only nut need be unscrewed, then make circular hole relative with nut by mobile on pressing plate, pressing plate is taken off from double threaded screw, the dismounting of product can be completed, more next product to be processed can be installed according to the method described above, thus when avoiding dismantling workpiece, all need the problem backed out by nut at every turn, make operation more simple, increase work efficiency.
In sum, this device effectively to the product location to be processed shown in Fig. 1, can ensure the stability of product location and the convenience of handling, improves the quality of products and operating efficiency.
