In order to achieve the above object, the present invention provides the following technical solutions:
a clamping jig for processing a countersunk hole in a fixed seat comprises a base, a supporting plate, a central positioning disc and a central pressing disc; the supporting plates are positioned on the base, the number of the supporting plates is two, the supporting plates are arranged in a crossed manner, the supporting plates are vertically arranged, positioning grooves are formed in the top ends of the supporting plates, and side positioning flanges are arranged at two ends of each positioning groove; the central positioning disk is positioned at the central position in the positioning groove, a central screw hole is formed in the central positioning disk, and the central pressing disk is detachably connected with the central positioning disk through a locking screw.
Furthermore, the central pressing disc and the central positioning disc are both disc-shaped and coaxially arranged.
Furthermore, the diameter of the central pressing disc is larger than that of the central positioning disc, and the diameter of the central pressing disc is smaller than the length of the positioning groove.
Furthermore, the locking screw vertically penetrates through a through hole in the middle of the central pressing disc; and the external thread of the locking screw is matched with the internal thread of the central screw hole.
The utility model has the advantages that: the utility model provides a fixing base processing clamping tool for counter sink, through the base, a supporting plate, the constant head tank, the side location flange, the central positioning dish, the center compresses tightly the cooperation of dish and locking screw and uses, the centre bore that utilizes fixing base product itself compresses tightly the location to the side location flange compresses tightly the top surface that the dish all is less than the fixing base product with the center, thereby avoid producing the interference to the removal tool setting operation of drill bit and feed the action, be favorable to guaranteeing going on smoothly of processing counter sink screw hole.
