The existing adjustable turning tool has some defects when in use, the vibration reduction effect of the adjustable turning tool is poor, the surface of a cutting blade cutting workpiece is easy to be not smooth enough, and the adjustable turning tool is not convenient for fixing the cutting blades of different shapes, so that the use is inconvenient.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an adjustable lathe tool to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an adjustable lathe tool, includes the cutter arbor, the top of cutter arbor is provided with the connecting rod, the top fixedly connected with tool bit of connecting rod, the both ends of tool bit all are rotated through the pivot and are connected with the briquetting, first recess has been seted up to the preceding table wall of tool bit, and the back table wall of tool bit has seted up the second recess, the inside of first recess is provided with the cutting blade, the interior table wall of first recess and second recess all is provided with the rubber pad.

Preferably, the first groove and the cutting insert are fixedly connected by a fixing pin.

Preferably, the rubber pad is fixed with the first groove and the second groove through glue.

Preferably, the cutter arbor is the cuboid structure.

Preferably, the connecting rod and the cutter bar are of an integrated structure.

Preferably, the connecting rod and the cutter head are fixed by welding.

Compared with the prior art, the beneficial effects of the utility model are that:

this adjustable lathe tool is through setting up the rubber pad, and the rubber pad can reduce the cutting blade and add man-hour, because the cutting blade stretches out the vibration of tool bit length overlength and the cutting blade that produces, avoids the vibration of cutting blade to lead to the work piece surface not smooth and clean enough in the course of working.

This adjustable lathe tool is through setting up the second recess, and the second recess is different with first recess shape, and the different cutting blade of tool bit mountable of being convenient for can change different cutting blade according to the demand of difference, has increased the practicality of tool bit.

Drawings

Fig. 1 is a schematic structural view of the present invention;

fig. 2 is a rear view of the present invention;

fig. 3 is a schematic view of the disassembled structure of the cutting insert of the present invention.

In the figure: 1. a cutting insert; 2, fixing pins; 3. a connecting rod; 4. a cutter bar; 5. a rotating shaft; 6. a cutter head; 7. briquetting; 8. a first groove; 9. a rubber pad; 10. a second groove.

Detailed Description

The present invention will be further described with reference to the following examples.

The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention. The condition in the embodiment can be further adjusted according to concrete condition the utility model discloses a it is right under the design prerequisite the utility model discloses a simple improvement of method all belongs to the utility model discloses the scope of claiming.

Referring to fig. 1-3, the utility model provides an adjustable lathe tool, including cutter arbor 4, the top of cutter arbor 4 is provided with connecting rod 3, the top fixedly connected with tool bit 6 of connecting rod 3, and the both ends of tool bit 6 all are rotated through pivot 5 and are connected with briquetting 7, and first recess 8 has been seted up to the preceding table wall of tool bit 6, and the back table wall of tool bit 6 has seted up second recess 10, and the inside of first recess 8 is provided with cutting blade 1, and the interior table wall of first recess 8 and second recess 10 all is provided with rubber pad 9.

In the above scheme, the rubber pad 9 can reduce the cutting blade 1 and add man-hour, because the cutting blade 1 stretches out the cutting blade 1 vibration that 6 length overlengths of tool bit produced, the vibration of avoiding cutting blade 1 in the course of working leads to the work piece surface not bright and clean enough, and second recess 10 is different with first recess 8 shape, and the different cutting blade 1 of tool bit 6 mountable of being convenient for can change different cutting blade 1 according to the demand of difference, has increased the practicality of tool bit 6.

In particular, the first groove 8 and the cutting insert 1 are fixedly connected by the fixing pin 2, facilitating replacement of the cutting insert 1.

Specifically, rubber pad 9 all passes through glue with first recess 8 and second recess 10 and pastes fixedly, is convenient for increase rubber pad 9's fastness.

Specifically, the cutter bar 4 is of a cuboid structure, so that the guide rod 4 can be conveniently used.
