Description
Technical field
The utility model relates to a kind of fixed jig, particularly a kind of fixed jig of tiny punching pin grinding.
Background technology
The 3C industry is toward littler now, and more accurate direction develops, and corresponding accessory also dwindles accordingly, thereby makes more tiny that the mould parts of producing this kind accessory also becomes.When tradition is ground tiny punching pin used fixed jig as shown in Figure 1, it be conventional brace, and punching pin 201 is placed on both sides or the section grooves 202, hand-tight make-up handgrip 203 is fixed, then with the head of the grinder buffing punching pin 201 on the grinding machine.The security of this kind fixed jig is low, and punching pin can rock in process, the easy breakdown of tiny punching pin that processes, and once can only process a punching pin, grinding trimming efficient is extremely low.
The utility model content
At the technical problem that exists in the prior art, the fixed jig that the purpose of this utility model is to provide a kind of punching pin fixation and the high tiny punching pin of grinding efficiency to grind.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
The fixed jig that a kind of tiny punching pin grinds, comprise a body and on lead a piece, described body is provided with several punching pin shank locating slots, this punching pin shank locating slot runs through whole body, the inboard at described body two ends respectively is vertically installed with a fixedly guide pillar, lead a piece on described and be provided with several and described punching pin shank locating slot punching pin blade part locating slot one to one, lead on described
The inboard at piece two ends, position respectively is provided with a dowel hole that matches with described fixedly guide pillar, lead an outside at piece two ends on described and respectively be provided with a through hole that is through to described dowel hole from outside to inside, lock-in component inserts described through hole, is one with leading a piece and body on described sealed by described fixedly guide pillar.
Further, the tiny punching pin with required grinding is corresponding one by one respectively for the diameter of described punching pin shank locating slot and described punching pin blade part locating slot.
Further, the monolateral gap between described punching pin shank locating slot and the punching pin shank is less than 0.01mm.
Further, the monolateral gap between described punching pin blade part locating slot and the punching pin blade part is less than 0.005mm.
Further, described through hole is the thread through hole.
Further, described lock-in component is screw or bolt.
Technique scheme has following beneficial effect: this fixed jig is the shank of tiny punching pin and blade part to be positioned fixing respectively, and in process, difficult generation is rocked, safe, and, can grind several tiny punching pines of trimming simultaneously, working (machining) efficiency is higher.It is corresponding that the punching pin shank locating slot of this fixed jig and punching pin blade part locating slot can arrange the size of tiny punching pin of its diameter and required grinding, can realize being suitable for the purpose of multiple tiny punching pin.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with the specific embodiment of the present utility model and conjunction with figs. this patent is elaborated.
Description of drawings
Fig. 1 is traditional tiny punching pin grinding fixed jig structural representation.
Fig. 2 is the exploded perspective view of the fixed jig of the tiny punching pin grinding of the utility model.
Fig. 3 is the solid combination schematic diagram of the fixed jig of the tiny punching pin grinding of the utility model.
The specific embodiment
As shown in Figures 2 and 3, the fixed jig that a kind of tiny punching pin of the present utility model grinds, comprise a body 101 and on lead a piece 102, body 101 is provided with several punching pin shank locating slots 103, this punching pin shank locating slot 103 runs through whole body 101, and the inboard at body 101 two ends respectively is vertically installed with a fixedly guide pillar 104.On lead a piece 102 and be provided with several and punching pin shank locating slot 103 punching pin blade part locating slot 105 one to one, on lead a piece 102 two ends the inboard respectively be provided with a dowel hole 106 that matches with fixing guide pillar 104, on lead a piece 102 two ends the outside respectively be provided with a through hole 108 that is through to described dowel hole 106 from outside to inside, in the present embodiment, this through hole 108 is the thread through hole.Lock-in component 107 inserts described through hole 108, will on to lead a piece 102 and body 101 sealed by fixing guide pillar 104 be one.Wherein, lock-in component 107 can be screw or the bolt that matches with through hole 108.
In addition, the tiny punching pin with required grinding is corresponding one by one respectively for the diameter of punching pin shank locating slot 103 and punching pin blade part locating slot 105, has realized that a kind of fixed jig is suitable for the purpose of multiple tiny punching pin.
Monolateral gap between punching pin shank locating slot 103 and the punching pin shank 109 is less than 0.01mm, and the monolateral gap between punching pin blade part locating slot 105 and the punching pin blade part 110 has guaranteed the fixation of punching pin shank 109 and punching pin blade part 110 less than 0.005mm.
When grinding tiny punching pin, punching pin shank 109 is put into punching pin shank locating slot 103 on the corresponding body 101, after putting into several punching pines successively, with on lead a piece 102 and be inserted in fixedly guide pillar 104 on the body 101, two dowel holes 106 contact two fixedly guide pillars 104 earlier, guiding punching pin blade part 110 cooperates the location with punching pin blade part locating slot 105, on lead after a piece 102 tops expose suitable punching pin trimming height, lock-in component 107 is inserted two through holes 108 of leading the outside, a piece 102 two ends, twist good lock-in component 107, thus by fixing guide pillar 104 will on lead a piece 102 and fixedly connected with body 101.With the grinder buffing punching pin blade part 110 on the grinding machine, finish grinding at last.
