Abstract
Provided is a general replaceable countersink reaming knife. The general replaceable countersink reaming knife comprises a knife rod and a blade. The upper end of the knife rod is a mohs cone handle which is matched with a drilling machine. The blade is fixed at the lower end of the knife rod. The general replaceable countersink reaming knife further comprises a locating column. The size of the locating column is corresponding to the size of a guide bottom hole of a to-be-processed countersink. The locating hole is connected with the blade and the bottom end of the knife rod through screws. The blade is arranged between the locating column and the knife rod. The blade is made of white steel or hard alloy materials. The general replaceable countersink reaming knife has the advantages of being capable of achieving processing of countersinks of different guide bottom holes by selection of locating columns of different diameter specifications, good in generality, reasonable in structure and convenient to use and maintain.
Description
Technical field
The utility model relates to a kind of general interchangeable counterbore countersink, is used for belonging to machine-building, processing technique field at the various counterbore of machine-building process processing.
Background technology
In the machine-building process, after the various hole of parts system machines, some parts is because assembling or other reasons, the end face of each hole system must be processed counterbore, and existing counterbore processing method comprises with the counterbore countersink of the drill bit transformation of the way, employing milling cutter directly mills counterbore or make special-purpose counterbore countersink processing etc.Above-mentioned several method deficiency separately is; During with the counterbore countersink processing counterbore of the drill bit transformation of the way, because accuracy of manufacture problem, may cause the counterbore end face processed uneven, counterbore and original bottom outlet axiality are poor, do not reach instructions for use.The method that adopts milling cutter directly to mill counterbore can cause the counterbore end face uneven equally, and counterbore and original bottom outlet axiality are poor, do not reach instructions for use.If make special-purpose counterbore countersink, can guarantee the requirements such as the precision of counterbore and position degree, but because special-purpose counterbore countersink head guide section is fixed structure, its versatility is poor, if the counterbore consistent size, when the pilot hole size not simultaneously, this special-purpose counterbore countersink then can not use.
The utility model content
The purpose of this utility model is to provide a kind of general interchangeable counterbore countersink for above-mentioned deficiency.The utility model adopts following proposal:
Described general interchangeable counterbore countersink, comprise knife bar and blade, the knife bar upper end is the Morse taper shank that cooperates with drilling machine, blade is fixed on the knife bar lower end, this counterbore countersink also is provided with locating dowel, this locating dowel is corresponding with the guiding bottom outlet size of counterbore to be processed, and locating dowel links to each other with the knife bar bottom with blade by screw, and blade is between locating dowel and knife bar.
Described blade is made with white steel knife or Hardmetal materials.
Adopt the beneficial effect of technique scheme to be: can by selecting the locating dowel of different-diameter specification, realize the counterbore processing of different guiding bottom outlets.Versatility is good, and is rational in infrastructure, and working service is convenient.
Description of drawings
Fig. 1 is the general interchangeable counterbore countersink example structure schematic diagram of the utility model.
Fig. 2 is that the described counterbore countersink of Fig. 1 M is to view.
Among the figure: 1-knife bar, 2-screw, 3-blade, 4-locating dowel, 5-screw.
The specific embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is elaborated:
As shown in Figure 1, general interchangeable counterbore countersink described in the utility model.Mainly formed by knife bar 1, blade 3, interchangeable locating dowel 4, wherein knife bar 1, interchangeable locating dowel 4 can adopt general machining process to machine, the Morse taper shank position that while knife bar 1 upper end cooperates with upright drill or radial drilling machine main shaft, must advise match grinding with the Morse's taper ring taps, contact area can be purchased greater than 80%.Blade 3 can be according to circumstances with white steel knife or the carbide chip transformation of the way.Above-mentioned parts on deck after, just can finish the making of this interchangeable counterbore countersink by operations such as assemblings, wherein blade 3 is fixed by screw 2 and knife bar 1 lower end, and interchangeable locating dowel 4 is fixing with blade 3 and knife bar 1 by screw 5, and blade is between knife bar and interchangeable locating dowel 4.
During the interchangeable counterbore countersink assembling of the utility model, can determine first the diameter dimension of blade 3 according to the counterbore size of product to be processed, guarantee that the cutting diameter scope of blade 3 satisfies the counterbore dimensional requirement of product to be processed.Then according to counterbore guiding bottom outlet size, select to be equipped with corresponding locating dowel 4, and locating dowel 4 loaded onto knife bar 1 and tighten.During use this counterbore countersink upper end Morse taper shank packed on upright drill or the radial drilling machine main shaft, namely can be used for processing counterbore.
Adopt the general interchangeable counterbore countersink of the utility model, when the different counterbore of upright drill or radial drilling machine processing guiding bottom outlet size, can make according to guiding bottom outlet size the locating dowel of various sizes, by changing the locating dowel 4 of this type counterbore countersink head, reach the counterbore of the different guiding of processing bottom outlet size.Simultaneously, if counter bore hole diameters is different, but the diameter difference is little, then can be by adjusting the blade clamping position of this interchangeable counterbore countersink, with the counterbore of processing different-diameter.The utility model design principle is reliable, and versatility is good, and is rational in infrastructure, and clamping is simple, and positioning accuracy is high, and working service is convenient.
