Further, described jaw is elasticity jaw.
Compared with prior art, the utility model adopts elasticity jaw to clamp, and utilizes cover plate to position, clamping is simple, clamps, the time of unclamping is short, improve production efficiency, and processing stability is high, can ensures that minor axis follows the axiality of major axis, ensure that the quality of converted products.
Accompanying drawing explanation
Accompanying drawing 1 is the main TV structure schematic diagram of the frock clamp of machining crankshafts minor axis described in the utility model;
Accompanying drawing 2 is structural representations of pressing plate shown in accompanying drawing 1.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually, below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
As shown in Figure 1, a kind of frock clamp of machining crankshafts minor axis, for processing the minor axis of bent axle in compressor, comprise base 1, sleeve 2 and chuck 3, described sleeve 2 is cylindrical, described sleeve 2 is bolted on base 1, sleeve 2 inside has spatial accommodation 21, chuck 3 is arranged in the spatial accommodation 21 of sleeve 2, sleeve 2 top is bolted a cover plate 22, chuck 3 is enclosed in spatial accommodation 21 by cover plate 22, the through hole 23 stretched out for chuck 3 is had in the middle part of cover plate 22, location-plate 24 is provided with in through hole 23, location-plate 24 is for the location and installation of workpiece.
Described base 1 is arranged on lathe by a ring flange, the passage 11 supplying the push rod of the hydraulic cylinder on lathe to pass through is had in the middle part of base 1, base 1 is provided with the boss 12 of an annular, boss 12 is for installing chuck 3, boss 12 is provided with slide bar 13, slide bar 13 has 4, each slide bar 13 is provided with a sliding sleeve 14, and sliding sleeve 14 can slide on slide bar 13.
The major diameter fit of described sleeve 2 and boss 12 ring set in the outside of boss 12, for the protection of chuck 2.
Described chuck 3 is for holding workpiece, comprise jaw 31, arm-tie 32, pressing plate 33 and jaw cover 34, described arm-tie 32 is connected with sliding sleeve 14, arm-tie 32 is provided with withstanding part 321, withstanding part 321 is positioned in the course of the passage 11 offered in the middle part of base 1, described jaw 31 is arranged on arm-tie 32 by jaw cover 34, jaw 31 is elasticity jaw or scroll chuck, wherein preferred elastomeric jaw, during use, at the push rod apical grafting of hydraulic cylinder on withstanding part 321, arm-tie 32 is slided on slide bar 13, jaw 31 moves forward and clamps workpiece under the promotion of arm-tie 32, further, jaw 31 is dismountable to be arranged on jaw cover 34, the jaw 31 of different size can be selected according to the size of workpiece during work, described pressing plate 33 is arranged on the inwall of sleeve 2 front end, as shown in Figure 2, described pressing plate 33 is cylindrical, the position of the corresponding jaw 31 of pressing plate 33 has groove 331, the inwall that groove 331 has inclination makes the tapered structure of groove 331, and the diameter of the groove 331 of close jaw 31 one end is greater than the diameter of the groove 331 away from jaw one end, jaw 31 tightens up gradually in protruding process under the effect of the inwall of groove 331 inclination, thus workpiece is stepped up.
