Abstract
The utility model provides an automatic middle-partitioning fixture for milling the two side surfaces of a coupler yoke. The automatic middle-partitioning fixture comprises a bottom plate, a support plate and a screw rod group, wherein the support plate is fixed on the bottom plate, and a pair of screw rod holes is formed in the support plate; the screw rod group comprises a first screw rod, a nut sleeve and a second screw rod which are sequentially connected; the first screw rod and the second screw rod are installed in the screw rod holes of the support plate, and provided with grooves respectively; and bolts corresponding to the grooves are arranged on the support plate. The automatic middle-partitioning fixture provided by the utility model is simple in structure and convenient to operate; and an automatic middle-partitioning requirement on the two side surfaces of the coupler yoke is realized by virtue of the matching between the two bidirectional screws and the nut sleeve, thus ensuring the machining accuracy of the two side surfaces of a yoke body, and providing an accurate reference surface for subsequent machining.
Description
Technical field
The utility model relates to machining apparatus, is specifically related to a kind of frock clamp.
Background technology
Hook tail frame is the important spare part of railway freight-car accessory coupler buffering device, in machining assembling process, the processing of Gou Weikuang two sides seems particularly important as first manufacturing procedure, because two lateral surfaces of this procedure processing hook tail frame provide datum level for multiple working procedure later, particularly important so seem, yet traditional frock clamp cannot guarantee minute middle requirement automatically of Gou Weikuang two sides, or precision is not high, cannot guarantee the uniformity of Gou Weikuang two sides thickness processing dimension, when later process Yi Gouweikuang two sides are during as benchmark, cause workpiece to be scrapped.
Utility model content
Utility model object: the utility model, for the problems of the prior art, provides the automatic minute frock for Xi Gouweikuang two sides that a kind of clamping is simple, precision is high.
Technical scheme: for solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of automatic minute frock for Xi Gouweikuang two sides, comprise base plate, gripper shoe and screw rod group, described gripper shoe is fixed on base plate and gripper shoe is provided with a pair of screw hole, described screw rod group comprises the first screw rod, nut sleeve and the second screw rod connecting successively, and described the first screw rod and the second screw rod are arranged in the screw hole of gripper shoe.And on the first screw rod and the second screw rod, be equipped with groove, and be provided with the pin corresponding with groove in gripper shoe, insert.
The utility model arranges two screw rods and connects and be combined into reverse-flighted screw by nut sleeve in gripper shoe, and establish groove on the first screw rod and the second screw rod, and be provided with the pin corresponding with groove in gripper shoe, insert, pin inserts in groove, when adjusting nut overlaps, pin is inserted the rotation that can prevent screw rod self, thereby screw rod two ends are ejected, and reaches the requirement in automatically dividing.
Wherein, the number of described screw rod group and gripper shoe is identical, is 2 groups.
Wherein, the utility model also comprises two support bars, and described support bar is fixed on base plate and the head of every support bar is equipped with pressing plate; Pressing plate can better be pushed down workpiece, guarantees to add the precision in man-hour.
Wherein, also comprise head supporting seat, described head supporting seat is arranged on base plate; Head supporting seat can make hook tail frame better be fixed in frock, guarantees to add stability in man-hour.
Wherein, the connecting portion of described base plate and gripper shoe is also provided with reinforcement, and reinforcement can make gripper shoe more firm with being connected of base plate.
Beneficial effect: compared with prior art, the utlity model has following advantage: the utility model is simple in structure, easy to operate, utilize the cooperation of two reverse-flighted screws and nut sleeve, realize minute middle requirement automatically of Gou Weikuang two sides, guaranteed the machining accuracy of framework two sides, for follow-up processing provides datum level accurately.
