Abstract
The utility model discloses a kind of filter apparatus based on punching press cover plate, comprise filter cavity and cover plate assembly, described cover plate assembly is arranged on filter cavity, also comprise lock-screw, punching press cover plate, tuning self-locking screw, described tuning self-locking screw is connected with punching press cover plate by screw by described punching press cover plate, and described punching press cover plate is fixed on described filter cavity by lock-screw.The utility model replaces traditional cover plate assembly that presses by adopting punching press aluminum cover plate assembly, greatly can shorten the technical process of filter, without the need to self-clinching nut again on aluminum cover plate, adopt the process of punching press flange and tapping, fix tuning self-locking screw, owing to no longer needing to use self-clinching nut, the cost of cover plate assembly can reduce greatly, also can enhance productivity simultaneously, alleviate the weight of filter apparatus.Punching press and turn-up process can complete by punch press is disposable, and tapping process also can carry out tapping by servo tooth machining unit simultaneously, therefore greatly can improve the production efficiency of cover plate assembly, reduce process costs.
Description
Technical field
The utility model relates to the technical field of signal transacting, particularly a kind of filter apparatus based on punching press cover plate.
Background technology
The aluminium sheet that the cover plate of traditional filter of current use generally adopts, self-clinching nut is fixing on the cover board by the process pressed, and then is screwed in self-clinching nut by tuning screw.Aluminum cover plate, in the process pressed, can produce larger distortion, affects the quality of regulation of signal.In the process pressed, can self-clinching nut be used, also can add the cost of filter, and this technical process is comparatively complicated, reduce the production efficiency of filter lid board component.
Utility model content
The purpose of this utility model is that the shortcoming overcoming prior art is with not enough, provides a kind of filter apparatus based on punching press aluminum cover plate.
The purpose of this utility model is achieved through the following technical solutions:
A kind of filter apparatus based on punching press cover plate, comprise filter cavity and cover plate assembly, described cover plate assembly is arranged on filter cavity, also comprise lock-screw, punching press cover plate, tuning self-locking screw, described tuning self-locking screw is connected with punching press cover plate by screw by described punching press cover plate, and described punching press cover plate is fixed on described filter cavity by lock-screw.
Preferably, described punching press cover plate is punching press aluminum cover plate, by the technical process on described aluminum cover plate upper punch pressure limit and tapping, fixes tuning self-locking screw.
Preferably, described punching press aluminum cover plate does not re-use self-clinching nut, greatly can reduce the production cost of cover plate assembly, and improve the evenness of aluminum cover plate.
Preferably, described punching press aluminum cover plate completes the processing of punching press flange and tapping by punch press and servo tooth machining unit.
The utility model has following advantage and effect relative to prior art:
1, the utility model replaces traditional cover plate assembly that presses by adopting punching press aluminum cover plate assembly, greatly can shorten the technical process of filter, without the need to self-clinching nut again on aluminum cover plate, adopt the process of punching press flange and tapping, fix tuning self-locking screw, owing to not needing to use self-clinching nut, the cost of cover plate assembly can reduce greatly, alleviates weight simultaneously.
2, the utility model is due to without the process of pressing, and the evenness of cover plate can improve greatly.Punching press and turn-up process can complete by punch press is disposable, and tapping process also can carry out tapping by servo tooth machining unit simultaneously, therefore greatly can improve the production efficiency of cover plate assembly, reduce process costs.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but execution mode of the present utility model is not limited thereto.
Embodiment
As shown in Figure 1, the filter apparatus based on punching press aluminum cover plate of the present embodiment, comprise filter cavity 1 and cover plate assembly 2, described cover plate assembly 2 is arranged on filter cavity 1, also comprise lock-screw 3, punching press aluminum cover plate 4, tuning self-locking screw 5, described punching press aluminum cover plate 4 passes through the technical process of punching press and tapping, be connected with punching press aluminum cover plate 4 by screw thread by described tuning self-locking screw 5, described punching press aluminum cover plate 4 is fixed on described filter cavity 1 by lock-screw 3.
Cover plate in the present embodiment is punching press aluminum cover plate 4, punch press is adopted aluminum cover plate 4 to be carried out to the processing of punching press flanging process, servo tooth machining unit is adopted to carry out the processing of tapping technique, technical process comparatively traditional approach efficiently facilitates, therefore greatly can improve the production efficiency of cover plate assembly, reduce process costs.
Do not need in the present embodiment to adopt self-clinching nut to fix tuning self-locking screw 5, but tuning self-locking screw 5 is directly connected on punching press aluminum cover plate 4 by screw thread.Like this, save self-clinching nut, reduce the cost of filter lid board component 2, also solve the aluminum cover plate 4 brought due to pressure-riveting process and be out of shape larger problem.
Above-described embodiment is the utility model preferably execution mode; but execution mode of the present utility model is not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection range of the present utility model.
