Abstract
The utility model discloses a special frock of thin wall non ferrous metal trisection groove has base location support and location mandrel, the base is a round stair structure, sets up an annular in base round platform center department for the pin location, the location mandrel also is round structure, and with the base cooperation, inserts the locating pin, can appear as an organic whole. The device aims at the processing of various thin-wall nonferrous metal groove parts, particularly the technical requirements of some parts, three equally-divided grooves are arranged in the middle of the tail part of the part, the precision size has strict requirements, the smoothness on two sides of the groove is also required to be higher, the requirements on the size and the precision can be effectively ensured through the positioning processing of the device, and the smoothness is also well ensured. The device has simple structure, convenient use, stability and reliability, improves the processing efficiency, and avoids the scrapping of parts caused by unequal division of three grooves in processing and polishing by a subsequent bench worker.
Description
Technical Field
The utility model relates to a thin wall non ferrous metal processing technology field mainly relates to a special frock of thin wall non ferrous metal trisection groove.
Background
With the expansion of the market, the number of special products is continuously increased, and the structural design of the thin-wall nonferrous metal with the trisection lens barrel part is more and more widely applied to the whole mechanical field. The machining of the thin-wall nonferrous metal three-equal-part groove is diversified, in the traditional machining, the allowance is machined firstly through a numerical control milling machine, then a special tool and an electrode are manufactured through electric pulse, electric beating is conducted, after the electric pulse machining, the smoothness of two side faces is poor, and later-stage manual sanding is needed. In a word, some existing processing modes adopted at present have the disadvantages of low universality, low efficiency, low processing precision, uneven trisection, long processing period, labor and time waste, high waste and easy waste generation in the manufacturing process. Therefore, how to rapidly and reasonably improve the efficiency of the thin-wall non-ferrous metal lens barrel type parts, avoid scrapping and ensure the processing quality of the parts is more critical.
SUMMERY OF THE UTILITY MODEL
For solving the above-mentioned defect that prior art exists, the utility model provides a special frock of thin wall non ferrous metal trisection groove has thoroughly solved the processing problem of this type of thin wall non ferrous metal lens cone part, and the commonality is good, can realize polytype thin wall non ferrous metal lens cone processing location problem, and machining efficiency is high.
In order to achieve the purpose, the utility model adopts the technical proposal that: a special tool for a thin-wall non-ferrous metal trisection groove comprises a base with a positioning and supporting function, wherein the base is of a circular structure, and a circular groove is formed in the center of a circular table of the base and used for positioning a positioning pin; the positioning mandrel is also of a circular structure and is matched with the base, a positioning hole is formed in the positioning mandrel, the positioning pin can be inserted into the annular groove through the positioning hole, so that the base and the positioning mandrel are in a shape of a first, and the positioning mandrel can rotate around the base by 360 degrees.
Furthermore, the number of the positioning holes on the positioning mandrel is 3, and the positioning holes are uniformly distributed on the positioning mandrel and are ++
The trisection slot can be conveniently and quickly positioned, and the processing efficiency is convenient to improve.
Compared with the prior art, adopt above-mentioned technical scheme's beneficial effect: the utility model provides a special frock of thin wall non ferrous metal trisection groove is applied to thin wall non ferrous metal lens cone class part, and the structural design of the part that specially for having the trisection, the precision requirement is higher processes, through the rotation of location mandrel, can realize that the part is rotatory on the base to realize the trisection processing of part trisection. The novel positioning device has the advantages of simple structure, convenience in use, reliability in positioning, high machining efficiency and the like, and can be popularized to batch machining of similar parts.
Drawings
FIG. 1 is a schematic view of the structure of the present invention in an assembled state;
fig. 2 is a schematic structural diagram of the present invention in an operating state.
Detailed Description
Referring to fig. 1, the utility model discloses a special frock of thin wall non ferrous metal trisection groove has the integrative integrated equipment who comprises base 1 location support, locating pin 2 and location mandrel 3 triplex. The positioning pin 2 is inserted into a positioning hole of the positioning mandrel 3 and an annular groove in the center of the circular truncated cone of the base 1, so that the base 1 and the positioning mandrel 3 are integrated, the positioning pin 2 is loosened, and the positioning mandrel 3 can rotate 360 degrees around the base 1.
Referring to fig. 2, the utility model discloses a special frock of thin wall non ferrous metal trisection groove is through the fixed centre gripping of slotting tool 4 on drilling machine drill chuck 6, and slotting tool 4 can move from top to bottom, and part 5 is packed into in the location mandrel 3.
This neotype theory of operation: under normal conditions, firstly, three equally-divided slots with reserved amount are machined in the middle of the tail of a part through numerical control, the slots are machined by slotting tools 4, the slotting tools 4 are machined by white steel bars, and the width of the slots can be controlled by the slotting tools 4; then, by using the assembled tool shown in figure 1, a part 5 is arranged behind the positioning mandrel 3 on a bench drill; and finally, moving the handle of the drilling machine by hand in sequence to drive the slotting tool 4 up and down to process the first square groove, loosening the positioning pin 2, rotating the positioning mandrel 3 by 120 degrees, inserting the positioning pin 2, processing the second square groove, and sequentially processing the third square groove.
