Abstract
Provided is a machining mold of a needle rod swing connecting rod. The machining mold comprises a machine frame. The machining mold is characterized in that the machine frame is provided with a base plate and a vertical plate perpendicular to the base plate, the vertical plate is provided with a first locating post and a second locating post, the first locating post and the second locating post respectively abut against the large end and the small end of the needle rod swing connecting rod. A first clamping plate and a second clamping plate capable of compressing or loosening the needle rod swing connecting rod are respectively arranged at the front ends of the first locating post and the second locating post. Compared with the prior art, the machining mold has the advantages that locating posts respectively corresponding to to-be-machined holes of work-pieces are directly arranged on the vertical plate of the mold so that after the work-pieces are clamped at a time, a plurality of the to-be-machined holes can be machined at the same time, machining efficiency is improved, clamping times are reduced, machining errors caused by repeated clamping can be controlled effectively, and machining quality of the work-pieces can be improved beneficially.
Description
Technical field
The utility model relates to a kind of processing mold of shank swing connecting bar.
Background technology
as shown in Figure 3, it is a kind of design of part schematic diagram of shank swing connecting bar 7, this shank swing connecting bar is used for sewing machine, its global shape is flat, shank swing connecting bar 7 has stub end 71 and the microcephaly holds 72, stub end 71 and microcephaly hold 72 to offer respectively the first locating hole 711 and the second locating hole 721 on flat horizontal surface, wherein, stub end 71 also has the first perpendicular projection of axis of an axis and the first locating hole 711, need to process the first vertical hole 712 on this first projection, the microcephaly holds 72 to have equally axis and perpendicular the second projection 722 of the second locating hole 721, also need to process the second perpendicular vertical hole (not shown) of axis of an axis and the second locating hole 721 on this second projection 722.
Traditional mould that clamps, because clamping structure is comparatively simple, can only process one of them hole to be processed on the shank swing arm after each the installation, can't process simultaneously the first vertical hole and the second vertical hole of shank swing connecting bar, cause working (machining) efficiency low, and the accumulated error that repeatedly clamps rear generation is large, awaits to do further improvement.
The utility model content
Technical problem to be solved in the utility model be provide for above-mentioned prior art present situation a kind of working (machining) efficiency higher and the location more reliable shank swing connecting bar processing mold.
The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of processing mold of shank swing connecting bar, comprise frame, it is characterized in that: the riser that described frame has base plate and arranges perpendicular to this base plate, be provided with the first locating dowel and the second locating dowel that can be respectively offset with workpiece stub end and the little head end of shank swing connecting bar on described riser, and the front end of described the first locating dowel and the second locating dowel is respectively arranged with the first clamping plate and second clamping plate that can compress or unclamp described shank swing connecting bar.
In order to improve the reliability of positioning of workpiece, further improve the machining accuracy of workpiece, as preferably, described riser also is provided with the limited post that can offset with the stub end of shank swing connecting bar at the oblique upper that is positioned at described the first locating dowel.
In order to clamp with easy to operate, as preferably, be provided with on described the first clamping plate can drive these first clamping plate near or away from the first spanner of described riser.
In order to clamp with easy to operate, as preferably, be provided with on described the second clamping plate can drive these second clamping plate near or away from the second spanner of described riser.
In order to improve machining accuracy and the degree of accuracy, as preferably, the top of described riser also is respectively arranged with the first drill bushing and the second drill bushing in the position of described the first locating dowel of correspondence and described the second locating dowel, offer on described the first drill bushing can be corresponding with the first hole to be processed on the shank swing connecting bar first boring, offer on described the second drill bushing can be corresponding with the second generation machining hole on the shank swing connecting bar second boring.
Compared with prior art, the utility model has the advantage of: locating dowel corresponding to hole difference to be processed that energy and workpiece directly are set on the riser of mould, after making workpiece once clamp, can process simultaneously a plurality of holes to be processed, improved working (machining) efficiency, reduce clamping times, can effectively control and repeatedly clamp the mismachining tolerance that causes, be conducive to improve the crudy of workpiece.
Description of drawings
Fig. 1 is that the processing mold of the utility model embodiment uses state diagram.
Fig. 2 is partial exploded view shown in Figure 1.
Fig. 3 is the structural representation of shank swing connecting bar of the prior art.
The specific embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, the present embodiment discloses a kind of processing mold for the shank swing connecting bar, this processing mold comprises frame, the riser 2 that frame has base plate 1 and arranges perpendicular to this base plate 1, be provided with the first locating dowel 21 and the second locating dowel 22 that can be respectively offset with stub end and the little head end of shank swing connecting bar 7 on riser 2, and the front end of the first locating dowel 21 and the second locating dowel 22 is respectively arranged with the first clamping plate 3 and second clamping plate 4 that can compress or unclamp the shank swing connecting bar; Wherein, be provided with on the first clamping plate 3 can drive this first clamping plate 3 near or the first spanner 31, the second clamping plate 4 away from riser 2 on be provided with can drive these second clamping plate 4 near or away from the second spanner 41 of riser 2.
For the reliability that guarantees that shank swing connecting bar 7 clamps, prevent that shank swing connecting bar 7 work in-processes are moved, riser 2 also is provided with the limited post 23 that can offset with the stub end of shank swing connecting bar 7 at the oblique upper that is positioned at the first locating dowel 21;
The top of riser 2 also is respectively arranged with the first drill bushing 5 and the second drill bushing 6 in the position of corresponding the first locating dowel 21 and the second locating dowel 22, offer on the first drill bushing 5 can be corresponding with the first hole to be processed on the shank swing connecting bar the first boring offer on 51, the second drill bushings 6 can be corresponding with the second generation machining hole on the shank swing connecting bar the second boring 61.
The processing mold of the present embodiment can be processed plural hole to shank swing connecting bar 7 simultaneously by once clamping, and is compared to the mould that clamps that originally can only process single hole and has higher operating efficiency, has saved the time of clamping.
