The end surface of the tool head is provided with two installation grooves for installing the blades. The two installation grooves are arranged in an aligned manner so that two blades can be installed flatly on the installation grooves. The blades are fixed to the tool head by fixing screws. A knife pad is arranged between the blades and the installation grooves. A blade pressure plate is arranged on the blades. The blade pressure plate is pre-tightened between the clamping screws and the tool holder, thereby pressing on the plane of the blades. When the above tool is used to process disk parts such as pulleys, two flatly arranged blades can process two sets of sizes of the parts at the same time, avoiding multiple cutting and retracting, and effectively improving work efficiency.

Description

A double large V-groove rough turning tool

technical field

The utility model relates to a lathe processing cutter, in particular to a lathe processing double-knife combined cutter, which is mainly suitable for processing disc parts such as belt pulleys.

Background technique

At present, in the lathe cutting industry, most of the known tools include a tool seat and a blade, which are combined into a complete tool by a firm screw. The head of the turning tool is only equipped with a blade, and some tools are connected with the blade and the tool seat. The cutter head also only includes one blade. When processing parts with the above-mentioned cutter, one turning tool index can only complete the processing of one set of sizes. Go to another turning tool position, and then quickly feed the tool to the workpiece position to process another set of dimensions. This single-head tool is less efficient in processing.

The technical solution adopted by the utility model to solve the technical problem is: a double large V-groove roughing tool, including a tool holder and a blade, one end of the tool holder is set as a cutter head, and the end surface of the cutter head is opened Two installation grooves for blade installation, the two installation grooves are arranged in alignment, so that the two blades can be flatly installed on the installation grooves.

The installation groove is configured as a V-shaped groove body, and the blade is configured as a diamond-shaped cutter body corresponding to the installation groove.

The blade is provided with a mounting hole, the mounting groove is provided with a screw hole corresponding to the mounting hole, and fixing screws are installed in the mounting hole and the screw hole.

A knife shim matched with the installation groove is arranged between the blade and the installation groove, and a through hole through which a fixing screw can pass is arranged on the knife shim.

It also includes a blade pressing plate, one end of the blade pressing plate is pre-tensioned between the clamping screw and the tool holder, and the other end is pressed against the upper plane of the blade.

The beneficial effects of the utility model are: a double-large V-groove roughing tool, including a tool holder and a blade, one end of the tool holder is set as a cutter head, and two blades are provided on the surface of the end of the cutter head. Mounting slot, the two mounting slots are aligned so that the two blades can be flatly installed on the mounting slot, the blade is fixed on the cutter head by a set screw, a knife shim is arranged between the blade and the mounting slot, and the blade is provided with The blade pressing plate, the blade pressing plate is pre-tightened between the clamping screw and the tool holder, so as to be pressed against the upper plane of the blade. When using the above tool to process disc parts such as belt pulleys, the two flat blades can process two sets of sizes of the part at the same time, avoiding multiple feeding and retracting of the tool, and effectively improving work efficiency.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Fig. 1 is a structural representation of the utility model;

Fig. 2 is a side view of the utility model;

detailed description

With reference to Fig. 1 to Fig. 3, Fig. 1 to Fig. 3 is the structural representation of a specific embodiment of the present utility model, as shown in the figure, a kind of double big V-groove rough turning tool, comprises tool rest 1, blade 2, described knife One end of the frame 1 is set as a downwardly inclined cutter head 11, and two mounting grooves 7 for the blade 2 are provided on the end surface of the cutter head 11, and the mounting grooves 7 are arranged as V-shaped grooves, and the The blade 2 is set as a rhombic cutter body corresponding to the installation groove 7, the blade 2 is installed on the installation groove 7, and the cutter head 11 is also used as a support for the blade 2 at the same time, which plays a role in shock absorption and prolongs the service life of the blade 2. , The two blades 2 can simultaneously process two sets of dimensions of the part, avoiding multiple feeding and retracting of the knife, and greatly improving work efficiency.

Preferably, the two mounting grooves 7 are aligned so that the two blades 2 can be flatly installed on the mounting grooves 7. When processing parts, the two flat blades 2 can simultaneously process the parts with the same effect and position Different two sets of sizes greatly improve work efficiency.

As preferably, the blade 2 is provided with a mounting hole 21, the mounting groove 7 is provided with a screw hole 12 corresponding to the mounting hole 21, and a fixing screw 5 is installed in the mounting hole 21 and the screw hole 12, so that the blade 2 Fixed and positioned in the installation groove 7, meanwhile, this structure facilitates the installation and removal of the blade.

As preferably, between the blade 2 and the mounting groove 7, a knife shim 3 that cooperates with the mounting groove 7 is provided, and the knife shim 3 is provided with a through hole that allows the fixing screw 5 to pass through, and the fixing screw 5 passes through the blade 2, The knife shim 3 and the knife rest 1 make the knife shim 3 fixed between the blade 2 and the knife rest 1, and the knife shim 3 protects the blade 2 while achieving shock absorption and can adjust the height of the blade 2.
