Abstract
A combined clamping type turning tool comprises a tool handle, a tool pad and a pressing plate, wherein a tool groove is formed at the front end of the tool handle, the tool pad is fixed inside the tool groove through a threaded pin, a blade is arranged on the tool pad, a through hole is formed in the blade, the pressing plate is screwed on a pressing plate platform arranged on the top portion of the tool groove through a pressing plate screw, a boss is arranged at the front end of the pressing plate, the boss is inserted into the through hole formed in the blade, and the bottom face of the boss is attached to the upper surface of the blade. The pressing plate is not directly pressed on the top face of the blade but attached to the blade with the combined method that the boss exerts radial force on the through hole of the blade and the bottom face of the boss exerts force on the top face of the blade. Accordingly, the clamp force is large, impact resistance is achieved, the contact area between the pressing plate and the blade is increased, clamping method is greatly simplified, fastening effect is good, parts machined while the blade is utilized are stable in quality and defective and waste products are reduced. In addition, the blade structure is simpler, and the machining capacity and the machining time of a tool body are reduced, and thus the auxiliary time is lowered, and production efficiency is improved.
Description
Technical field
The utility model relates to a kind of machining tool, especially relates to a kind of compound clamping type turning tool.
Background technology
Lathe tool for turning processing, have the cutter of a cutting tip, lathe tool is one of most widely used cutter in the turning processing.Lathe tool belongs to single cutting edge of a knife or a sword cutter, because turnery thing shape is different a lot of patterns is arranged, but the title at its each position and effect are identical, and a good lathe tool has the good handle of a knife of rigidity and sharp knife edge two large divisions.
Common lathe tool can be divided into monoblock type, welded type, mechanical clamping type by structure.The monoblock type lathe tool is that the lathe tool front end is processed into blade, and the welded type lathe tool is that carbide chip is welded in the cutter groove of cutter, and these two kinds of lathe tools are short service life, and blade can't be changed, and foundry goods is eliminated.Compound clamping type turning tool uses indexable insert tip, throw away tip; avoided by the defective of welding and sharpening causes; the geometric parameter of cutter is guaranteed by blade and insert groove fully; cutting ability is stable; production efficiency is high; can greatly reduce non-cutting times such as shutting down tool changing and sharpening, improve the utilization rate of knife bar, save cost.Existing its clamping method of mechanical clamping type turning tool is to use eccentric threaded that blade is fitted toward the extruding of cutter groove, then adding top board on blade compresses, and mode, the dynamics of this mode during to the tapered hole of cutter hub and the assembling of eccentric threaded requires all very high, assembly method is difficult to grasp, the slit occurs easily, cause that blade is fastening not, the underproof situation of converted products happens occasionally.
Summary of the invention
The utility model purpose provides a kind of compound clamping type turning tool, with solve existing lathe tool when blade assemble the assembly method complexity, fastening poor, the technical problem such as workpiece is of poor quality in slit, blade appears easily.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of compound clamping type turning tool, comprise handle of a knife, edge bearing, pressing plate, described handle of a knife front end is provided with the cutter groove, and edge bearing is fixed in the cutter groove by threaded, be provided with blade at edge bearing, be provided with through hole on the blade, described pressing plate is screwed on by plate screw on the pressing plate platform at cutter groove top, and this pressing plate front end is provided with a boss, this boss inserts in the insert through hole, and its boss bottom surface and blade upper surface are fitted.
As preferably, described cutter trench bottom is provided with the screw thread pin-and-hole, and cutter groove top is provided with edge bearing, and tapped through hole is set on the edge bearing, and edge bearing is fixed in the cutter groove by the tack threaded.
As preferably, described plate screw is double-threaded screw, and the thread rotary orientation at these double-threaded screw two ends is opposite, and wherein the pressing plate platform at an end and cutter groove top screws togather, and the other end and pressing plate screw togather.
As preferably, be provided with the blade binding face that cooperates with the blade sidewall in the described cutter groove.
The utlity model has the characteristics such as easy for installation, reliable results.Its pressing plate is not directly to press to put at the blade end face, but adopt boss blade the through hole radially application of force and this complex method applying of boss bottom surface blade end face application of force blade, clamping force is large, shock-resistant, pressing plate increases with the blade contact area, clamping method is simplified greatly, fastening effective, as to use this blade to process parts steady quality has reduced inferior, waste product; Structure of the cutter body is simpler, and cutter hub processing capacity and process time reduce, and have so just reduced non-cutting time, have improved production efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of structure shown in Figure 1;
Fig. 3 is installation diagram of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model, and Fig. 2 is the top view of structure shown in Figure 1, and Fig. 3 is installation diagram of the present utility model.As seen from the figure, this compound clamping type turning tool comprises handle of a knife 1, blade 8, threaded, pressing plate 10; Described handle of a knife 1 front end is provided with cutter groove 2, and cutter groove 2 bottoms are provided with screw thread pin-and-hole 3, and cutter groove 2 side elevations are provided with and the blade binding face 4 that cooperates with the blade sidewall.
Be provided with edge bearing 5 in the cutter groove 2, tapped through hole 6 is set on the edge bearing 5, edge bearing 5 is fixedly connected in the cutter groove 2 by threaded 7, and threaded 7 can be the smooth tack threaded of head, in order to blade is installed easily, rapidly.
When using this compound clamping type turning tool, first edge bearing 5 is placed in the cutter groove 2, with threaded 7 edge bearing 5 is locked, then blade 8 is placed on the edge bearing 5, pressing plate 10 is installed again, locking double-threaded screw 12, the boss 11 of pressing plate 10 is stretched in the insert through hole 9, draw the blade binding face 4 that is adjacent to cutter groove 2 sides from radially blade 8 being colluded, the bottom surface A of boss 11 and blade 8 upper surfaces are fitted fully, are compressed, and blade 8 is subject to the compound action of radial pull and top pressure like this, and clamping force is large, shock-resistant, can guarantee the stability when cutter uses.
At last, should be pointed out that the above specific embodiment only is the more representational example of the utility model.Obviously, the utility model is not limited to the above-mentioned specific embodiment, and many distortion can also be arranged.Any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done the above specific embodiment all should be thought to belong to protection domain of the present utility model.
