Abstract
The utility model discloses a fixture for connecting rod cover nut supporting face processing. The fixture comprises a base board, a connecting rod cover side face fixing board, a fastening board, a fixing board and a fastening bolt, the connecting rod cover side face fixing board and the fixing board are fixed to the base board at intervals in a parallel mode, one end of the fastening bolt penetrates through a threaded hole in the middle of the fixing board and corresponds to a groove in the middle of the fastening board, and a fixing groove fixing the two side faces of a connecting rod cover is formed between the connecting rod cover side face fixing board and the fastening board. The fastening board of the fixture and a jacking bolt can position a set of connecting rod covers arranged side by side at the same time, only one positioning process is needed for processing a plurality of connecting rod cover nut supporting faces of the connecting rod covers on a milling machine, processing efficiency is greatly improved, and labor intensity of operation workers is lowered.
Description
Technical field
The utility model relates to the Machining of Connecting Rod technical field, especially relates to connecting rod cap nut supporting surface fixture for processing.
Background technology
Connecting rod is the vitals of piston-mode motor.Connecting rod comprises gonnecting rod body and connecting rod cap, coordinates and is fixed by bolt and nut between gonnecting rod body and connecting rod cap, wherein, and the cooperation that contacts with connecting rod cap nut supporting surface of nut one end face, the Pingdu of connecting rod cap nut supporting surface, affect fixing stability.In the connecting rod production and processing, connecting rod cap nut supporting surface will be processed on milling machine, guarantees the Pingdu of connecting rod cap nut supporting surface, and existing clamp for machining once can only be located a connecting rod cap, and working (machining) efficiency is low.
The utility model content
For the prior art deficiency, technical problem to be solved in the utility model is to provide a kind of connecting rod cap nut supporting surface fixture for processing, and it once can locate a plurality of connecting rod caps, and working (machining) efficiency is high.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of connecting rod cap nut supporting surface fixture for processing, comprise substrate, also comprise connecting rod cap side fixed head, binding, fixed head, fastening bolt, described connecting rod cap side fixed head and fixed head spaced and parallel are fixed on substrate, described fastening bolt one end is corresponding with the groove at binding middle part through the screwed hole at fixed head middle part, forms the holddown groove of stationary links lid two sides between described connecting rod cap side fixed head and binding.
Be equipped with spring in the fastening bolt both sides between described fixed head and binding, two springs are identical to the distance of fastening bolt.
Be provided with fixed block between described bowl cover side fixed head and the same end of fixed head.
Described bowl cover side fixed head and fixed head the other end are provided with the bolt pedestal, are provided with in the bolt pedestal and hold out against the puller bolt that connecting rod cap is used.
The utility model compared with prior art, have the following advantages: binding and puller bolt by fixture can be located one group of connecting rod cap placed side by side simultaneously, on milling machine, the connecting rod cap nut supporting surface of a plurality of connecting rod caps of processing only needs one-time positioning, significantly improve working (machining) efficiency, alleviated operator's labour intensity.
The accompanying drawing explanation
Below to each width accompanying drawing of this specification, expressed content and the mark in figure are briefly described:
Fig. 1 is a kind of embodiment structural representation of the utility model fixture.
In figure: 1. substrate, 2. bolt pedestal, 3. connecting rod cap side fixed head, 4. fixed block, 5. fixed head, 6. binding, 7. fastening bolt, 8. connecting rod cap, 9. spring, 10. puller bolt.
The specific embodiment
Below contrast accompanying drawing, by the description to embodiment, the specific embodiment of the present utility model is described in further detail.
As shown in Figure 1, this connecting rod cap nut supporting surface fixture for processing, comprise substrate 1, connecting rod cap side fixed head 3, binding 6, fixed head 5, fastening bolt 7, fixed block 4, bolt pedestal 2, puller bolt 10; Wherein, connecting rod cap side fixed head 3 and fixed head 5 spaced and parallel are fixed on substrate 1, fastening bolt 7 one ends are corresponding with the groove at binding 6 middle parts through the screwed hole at fixed head 5 middle parts, fastening bolt 7 other ends are provided with rotary handle, form the holddown groove of stationary links lid two sides between connecting rod cap side fixed head 3 and binding 5.
Be provided with fixed block 4 between connecting rod cap side fixed head 3 and the same end of fixed head 5, be provided with bolt pedestal 2 at bowl cover side fixed head 3 and fixed head 5 the other end, be provided with in bolt pedestal 2 and hold out against the puller bolt 10 that connecting rod cap is used, the puller bolt outer end is hex nut.
Be equipped with spring 9, two springs between fixed head 5 and binding 6 in fastening bolt 7 both sides identical to the distance of fastening bolt, its spring is in compressive state, and balance binding two ends, guarantee the depth of parallelism between binding and fixed head.
The clamping method of this fixture comprises the following steps:
1), one group of connecting rod cap 8 is placed side by side between connecting rod cap side fixed head and binding, the most inboard connecting rod cap contacts with fixed block;
2), screw fastening bolt, promote binding, by connecting rod cap side fixed head and binding, one group of connecting rod cap two sides is clamped;
3), screw puller bolt, puller bolt holds out against the outermost connecting rod cap, and one group of connecting rod cap is fixed between puller bolt and fixed block.
Binding and puller bolt by fixture can be located one group of connecting rod cap placed side by side simultaneously, and on milling machine, the connecting rod cap nut supporting surface of a plurality of connecting rod caps of processing only needs one-time positioning.
The above is exemplarily described the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that design of the present utility model and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
