Abstract
The utility model discloses a kind of connecting rod screwed hole vehicle clamper, comprise base and reference seat, base one end is fixedly connected with lathe spindle, and the other end is fixedly connected with reference seat one end; The reference seat other end is the protruding semi arch datum level matching with connecting rod one end bush seat concaved circular cambered surface, and connecting rod one end bush seat concaved circular cambered surface is resisted against on the protruding semi arch datum level of the reference seat other end, is fixedly connected with base by securing member.The utility model is simple in structure, it is time saving and energy saving to operate, when car connecting rod screwed hole, only connecting rod bearing seat concaved circular cambered surface need be resisted against outside reference seat on protruding semi arch datum level, its upper and lower sides is by the semicircle positioning step location of reference seat upper and lower side, and connecting rod bearing seat and base are connected, can process at centering center.The utility model is without level of corrections, and operating efficiency is high, and can effectively guarantee the machining accuracy of connecting rod screwed hole.
Description
Technical field
The utility model relates to a kind of frock clamp, and especially a kind of tonnage machine pitman shaft, to the fixture of screwed hole, belongs to technical field of tooling clamps.
Background technology
Connecting rod is the vitals of forcing press, its one end is connected with bent axle, the other end is connected with ball screw upper end by axial thread hole, thereby bent axle power is passed to slide block by connecting rod, ball screw and ball cup, ball screw is used for regulating the distance of axis and slide block, thereby can adapt to the different closed height of mould.
At present, when tonnage machine connecting rod screwed hole, conventionally by connecting rod one end clamping on lathe chuck, then centering center, level of corrections is processed, correction is wasted time and energy, inefficiency, and the machining accuracy of connecting rod screwed hole is difficult to ensure, so just easily cause the stressed generation unbalance loading of the screw thread pair phenomenon between connecting rod screwed hole and ball screw, screw thread pair local pressure is excessive, finally causes screw thread pair to deform or damages, and then affecting the normal work of whole forcing press.
Utility model content
The purpose of this utility model be to provide a kind of simple in structure, operate time saving and energy saving, effectively to ensure connecting rod hole processing precision car connecting rod screwed hole fixture.
The utility model is achieved by the following technical programs:
A kind of connecting rod screwed hole vehicle clamper, comprises base and reference seat, and described base one end is fixedly connected with lathe spindle, and the base other end is fixedly connected with reference seat one end; The reference seat other end is the protruding semi arch datum level matching with connecting rod one end bush seat concaved circular cambered surface, and connecting rod one end bush seat concaved circular cambered surface is resisted against on the protruding semi arch datum level of the reference seat other end, is fixedly connected with base by securing member.
The purpose of this utility model can also further realize by following technical measures.
Aforesaid connecting rod screwed hole vehicle clamper, upper and lower side is arranged with semicircle positioning step outside wherein said reference seat, and connecting rod bearing seat upper and lower sides is located by semicircle positioning step respectively.
Aforesaid connecting rod screwed hole vehicle clamper, wherein said base other end end face middle part is provided with positioning spigot.
Aforesaid connecting rod screwed hole vehicle clamper, wherein said reference seat inner side end middle part extends outward circular positioning boss, and described circular positioning boss is positioned in the positioning spigot at base other end end face middle part.
Aforesaid connecting rod screwed hole vehicle clamper, wherein said reference seat middle part is also provided with assembling through hole.
The utility model is simple in structure, it is time saving and energy saving to operate, when car connecting rod screwed hole, only connecting rod bearing seat concaved circular cambered surface need be resisted against on protruding semi arch datum level, its upper and lower sides is by the semicircle positioning step location of reference seat upper and lower side, and connecting rod bearing seat and base are connected, can process at centering center; The utility model is without level of corrections, and operating efficiency is high, and can effectively guarantee the machining accuracy of connecting rod screwed hole.
Advantage and disadvantage of the present utility model, by for illustration and explanation the non-limitative illustration by preferred embodiment below, these embodiment, only provide as an example with reference to accompanying drawing.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the right view of Fig. 1;
Fig. 3 is that the A of Fig. 2 is to partial top view.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, Figure 2 and Figure 3, the utility model comprises base 1 and reference seat 2, base 1 left end screwed hole 12 screws with lathe spindle, base 1 right-hand member end face middle part is provided with positioning spigot 11, reference seat 2 for right-hand member be the semicircular arc piece of plane, this plane is extended circular positioning boss 21 left, and circular positioning boss 21 is positioned in the positioning spigot 11 at base 1 right-hand member end face middle part, and reference seat 2 is fixedly connected with base 1 right-hand member by 4 soket head cap screws 3.Reference seat 2 right-hand members are protruding semi arch datum level 22, as the positioning datum matching with connecting rod 4 left end bush seat concaved circular cambered surfaces, the two radius of curvature is identical, connecting rod 4 left end bush seat concaved circular cambered surfaces are resisted against on the protruding semi arch datum level 22 in reference seat 2 outsides, and are fixedly connected with base 1 by 4 groups of screws 5, cushion cover 6 and nut 7; 22 liang of protruding semi arch datum levels extend outward symmetrical semicircle positioning step 23 outward, and connecting rod 4 left end bush seat upper and lower sides are located by semicircle positioning step 23 respectively; Reference seat 2 centers are also provided with pilot hole 24, are convenient to assembling.
After the complete connecting rod 4 right-hand member screwed holes 41 of car system, unscrew screw 5, connecting rod 4 is taken off from reference seat 2, can carry out the processing of next connecting rod 4 screwed holes.
In addition to the implementation, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
