Description
Technical Field
The utility model relates to a screw line groove processing technology field, concretely relates to clamping device of screw class part line groove processing.
Background
The processing method of the screw straight-line groove is generally three, one is direct molding of a die, one is processing molding of a milling machine, and the other is processing molding of linear cutting. The die is directly formed, the processing speed is very high, the efficiency is very high, the cost is relatively low, but the defect is that the two sides of the straight groove can generate an external splayed shape, and the straight groove is not smooth; the straight groove processed and formed by the milling machine and the linear cutting machine is flat and smooth, two sides of the straight groove are not provided with an external splayed shape, but the straight groove needs to be clamped by a clamping device during processing, otherwise, the straight groove cannot be processed. The clamping mode mainly has that the bench vice presss from both sides tightly, the three-jaw chuck presss from both sides tightly, the clamp plate compresses tightly, when adopting the bench vice to press from both sides tightly, the three-jaw chuck presss from both sides tightly, once only can process a part, the clamping is frequent, and efficiency is extremely low, and workman intensity of labour is big, therefore the processing cost is higher, and the clamp force is difficult to control moreover, the condition that the screw thread was destroyed appears when the clamp force was too big easily, leads to scrapping, and the smaller screw is difficult to the clamping more.
When the pressing plate is adopted for pressing, for example, as shown in fig. 3, the upper die 11 and the lower die 10 are adopted for closing and clamping, a row of positioning holes 12 are formed between the upper die 11 and the lower die 10 for clamping screws, and the clamping efficiency is higher than that of the former two. However, the diameters of the screws have certain errors, and the clamping positions are different, so that the screws with larger diameters are easy to be clamped, the screws with smaller diameters are loosened, the processing of the straight-line groove is not facilitated, the processed finished product and the semi-finished product are mixed together, and even the screw threads with larger diameters can be damaged; secondly, the center of the positioning hole generates certain central symmetry deviation in the process of closing up and down, so that the symmetry degree of the milled straight-line groove relative to the axis center has certain deviation; and only one row of screws can be clamped, so that the operation is inconvenient, and the smaller screws are difficult to clamp.
