Abstract
The utility model discloses a sawing tool comprising a base (1), a connecting shaft (2) and a disc type cutter (3). A cavity is arranged in the middle of the base (1), the disc type cutter (3) is installed at one end of the connecting shaft (2), and the other end of the connecting shaft (2) is installed on the base (1). The sawing tool is characterized in that a blade is installed at one end of the connecting shaft (2) on the base (1) and extends into the cavity, and the cavity is provided with a vent hole which is communicated with the outside and vertical to the axis of the connecting shaft (2). When in processing, the sawing tool utilizes compressed air at working place as a power source so as to drive the disc type cutter (3) to rotate and cut a connecting part (8) of a process convex plate (7), a part (6) and the process convex plate (7) are separated, the cutting efficiency is high, a cylindrical locator (4) on the base moves along the outline of the separated part, the cutter can not damage the part, and the tool is light and can be held by hands, therefore, the operability is good.
Description
Technical field
The utility model relates to a kind of cutting tools, relates in particular to a kind of cutting tools that the connecting portion of false boss and part is separated.
Background technology
In mechanical manufacturing field, extensively the adopting process boss is as the assist location clamping method of part, false boss is being made when finishing and must be removed, and the normal mode that adopts is with the mode of boring round in the common mechanical industry, and the connecting portion of false boss with part separated.This method major defect has: the first, the junction of boss is by drill bit perforate one by one, all separate up to boss and part connecting portion, inefficiency, the second, boring uses air gun to clamp drill bit, in the process of boring, skew takes place and injuring part in drill bit easily, and the 3rd, air gun can only the less bit drills round of clamping diameter, for the deep trouth part, the mode operability of gang drill hole separating technology boss is poor.
Summary of the invention:
The technical problems to be solved in the utility model is to provide the cutting tools of the connecting portion of a kind of high efficiency, good operability and separating technology boss that can injuring part and part.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of cutting tools is provided, comprise base, connecting axle and disc type cutter, the middle part of described base has a cavity, described connecting axle one end is installed the disc type cutter, the connecting axle other end is installed on the base, it is characterized in that: described connecting axle one end that is installed on the base is equipped with blade and stretches in the cavity, described cavity have with outside that connect and with the passage of connecting axle axis normal, described passage one stomidium mouth is shaped on the internal thread that can be connected with the compressed air ozzle, described connecting axle is installed on the base by the bearing that is fixed on the base, described connecting axle is a step axle, end at axle is shaped on screw thread, and having keyway near the end of thread, described disc type cutter be connected axle key and connect, described base is a cubic block, the bottom surface of base is provided with orientation direction mechanism, two cylinder locators are installed by described orientation direction mechanism on the bottom surface of base, the handle that is used to hand is installed on the described base.
The utility model has following good effect than prior art.A kind of cutting tools of the present utility model, replace drill bit with the disc type cutter, cutting technique boss cutting efficiency height, the disc type cutter that different-diameter is installed can adapt to the separation of the boss connecting portion of different depth, in the cutting, cylinder locator on the base moves along separated parts profile, the disc type cutter can injuring part, and in addition, cutting tools utilizes the compressed air of workplace as power source, instrument is in light weight adopt hand-held, so good operability.
Description of drawings
Fig. 1 is the structural representation of a kind of cutting tools of the present utility model.
Fig. 2 is the use schematic diagram of a kind of cutting tools of the present utility model.
The specific embodiment
Below in conjunction with embodiment the utility model is further described.
Fig. 1 and Fig. 2 are a kind of cutting tools of the present utility model, comprise base 1, connecting axle 2 and disc type cutter 3, the middle part of described base 1 has a cavity, described connecting axle 2 one ends are installed disc type cutter 3, connecting axle 2 other ends are installed on the base 1, it is characterized in that: described connecting axle 2 one ends that are installed on the base 1 are equipped with blade and stretch in the cavity, described cavity have with outside that connect and with the passage of connecting axle 2 axis normal, described passage one stomidium mouth is shaped on the internal thread that can be connected with the compressed air ozzle, described connecting axle 2 is installed on the base 1 by the bearing that is fixed on the base 1, described connecting axle 2 is a step axle, end at axle is shaped on screw thread, and having keyway near the end of thread, described disc type cutter 3 is connected with connecting axle 2 keys, described base 1 is a cubic block, the bottom surface of base 1 is provided with orientation direction mechanism, described orientation direction mechanism is equipped with two cylinder locators 4 on the bottom surface of base 1, the handle 5 that is used to hand is installed on the described base 1.Add man-hour, the compressed air hose UNICOM of the passage of cutting tools and workplace, 7-8 atmospheric compressed air is input in the base 1, the blade that compressed air blows on the connecting axle 2 drives the coupling part 8 that disc type cutter 3 rotates cut-out false boss 7, and part 6 and false boss 7 are separated.Cylinder locator 4 one ends are installed in two precision holes of base 1 bottom surface by interference fit, the other end is exposed at base 1 outside, along the contour motion of separated workpiece 6, play the effect of location in the face of cylinder work of cylinder locator 4, can make cutting process more reliable and more stable.Handle 5 two ends have through hole, are connected with base 1 by screw, and handle 5 makes things convenient for the hand-held use of personnel at work.
