Abstract
The utility model discloses a processing jig comprising a positioning baseplate, a fixing plate and a positioning block, wherein the positioning block is fixed at the lower end of the fixing plate; an arc-shaped side surface I is arranged on the fixing plate; an arc-shaped side surface II is arranged on the positioning block and on the same side as the arc-shaped side surface I; and a positioning lug boss is arranged on the positioning baseplate. According to the processing jig, fast and accurate positioning is realized; time and labor are saved; the product qualification rate and the production efficiency are improved; and the production cost is reduced.
Description
Technical field
The utility model relates to the machined field, particularly a kind of processing jig.
Background technology
In processing, the part of complex contour is more common at present, the chain driving parts that starts as shown in Figure 1, and three faces (comprising the B face) of this part process when preparing stock, and other three faces then need CNC processing; The tow sides of this part are the plane, processing easily, but its side A is a cambered surface, has certain difficulty of processing.During processing A face, A is faced up facing to cutter, because the B face is a cambered surface also, part is difficult for clamping, so product is kept flat, processes the A face with the side of T type cutter.Semi-finished product after the positive and negative of part machined lie on the lathe, clamping, beat table, smoothing back processing A face, unload part after machining, and reprocess next part.Because this starts the tow sides more complicated of chain driving parts, be difficult for playing table, and part of every processing again clamping, play table, smooth, waste time and energy, working (machining) efficiency is low.
The utility model content
For solving the problems of the technologies described above, the utility model provides and has started chain driving parts processing jig, with realize quick accurately location, time saving and energy saving, improve product percent of pass purpose, enhance productivity, reduce production costs.
For achieving the above object, the technical scheme of the utility model is following:
A kind of processing jig comprises positioning plate, fixed head and locating piece, and said locating piece is fixed on the lower end of said fixed head; Said fixed head is provided with an arcuate flanks one, and said locating piece is provided with arcuate flanks two with said arcuate flanks one an identical side; Said positioning plate is provided with positioning boss.
Preferably, said locating piece is provided with locating hole, and said positioning plate is provided with positioning round table, and said positioning round table and said locating hole are complementary.
Preferably, also be provided with briquetting on the said fixed head.
Through technique scheme, the processing jig that the utility model provides utilizes the positioning boss locating element on the positioning plate, and positioning round table on the positioning plate and the locating hole on the fixed head are complementary, and positioning plate and fixed head positioning and fixing are in the same place; Arcuate flanks one on the fixed head is avoided blade, and the arcuate flanks two on the locating piece compresses part, prevents part deformation; Processing the back only needs fixed head, locating piece and briquetting are unloaded, and can take out part; When processing next part, only need fixed head, locating piece and briquetting are loaded good get final product, need not to beat again table, smooth.Therefore, adopt the utility model realized fast accurate location, time saving and energy saving, improve product percent of pass purpose, improved production efficiency, reduced production cost.

The specific embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment will be carried out clear, intactly description.
The utility model provides a kind of processing jig, shown in Fig. 2-4, comprises positioning plate 24, fixed head 22 and locating piece 23, and locating piece 23 is fixed on the lower end of fixed head 22; Fixed head 22 is provided with briquetting 21, and briquetting 21 is guaranteed the machining accuracy of part 41 with compressing between part 41 and the tool.Shown in Fig. 5-7, locating piece 23 is provided with locating hole 61, and positioning plate 24 is provided with positioning round table 51 and positioning boss 52, and positioning round table 51 is complementary with locating hole 61, and orientable hole is complementary on positioning boss 52 and the part 41.The A face of part 41 is a cambered surface, and processing A face is to accomplish with the side of T type cutter, runs into blade for fear of fixed head 22, and special fixed head 22 is provided with arcuate flanks 1; Arcuate flanks 1 is positioned at the same side with the A face, and both shapes are consistent.Side with T type cutter is processed the A face, and may there be distortion in part 41, deforms in order to prevent part 41, and the spy is provided with arcuate flanks 2 62 with the contacted end of B face on fixed head 22; Arcuate flanks 2 62 is consistent with the shape of B face, can the B face of part 41 be compressed.
Adopt the utility model processing as shown in Figure 1 start the chain driving parts, at first part is placed on the positioning plate 24, positioning boss 52 is stuck in the shrinkage pool of part, part is positioned; Then locating piece 23 and fixed head 22 are fixed, fixed head 22 is buckled on the part, positioning round table 51 is stuck in the locating hole 61, and locating piece 23 is had good positioning with positioning plate 24; At last briquetting 21 is pressed on the fixed head 22, the tool that part will be housed again is placed on the lathe, clamping, plays table, smoothing, processing.After processing a part, unload lower lock block 21, locating piece 23 and fixed head 22, part is taken out, place a part to be processed again on positioning plate 24, load onto fixed head 22, locating piece 23 and briquetting 21, need not to beat table, smooth and directly to process; Repeat above-mentioned action after machining and to reprocess next part.Positioning plate 24 is provided with positioning boss 52 and positioning round table 51, can part accurately be located, simultaneously also can be with tool accurate location between each plate up and down, and play table only need process first part the time, smooth, following process need not to repeat again.Therefore, realized fast accurate location, time saving and energy saving, improve product percent of pass purpose, improved production efficiency, reduced production cost.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation of spirit that does not break away from the utility model or scope in other embodiments among this paper.Therefore, the utility model will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
