Description

Improved tool for lathe

Technical Field

The utility model belongs to the technical field of machining, and particularly relates to an improved cutter for a lathe.

Background

Machining, often can need to use the lathe, and the cutter that uses on traditional lathe welds the blade on the tool row and welds a blade on each tool row mostly, along with add the blade grinding of number of times, when the blade grinding is accomplished, the tool row then scrapps to the use amount that leads to the tool row is big, leads to manufacturing cost to rise.

SUMMERY OF THE UTILITY MODEL

This neotype aim at: an improved tool for a lathe is provided.

In order to achieve the purpose, the novel technical scheme is as follows:

an improved cutter for a lathe comprises a blade, a cutter row and a cutter rest, wherein the front section and the rear section of the cutter row are respectively provided with a pressure groove, the blade is arranged in the pressure groove, the cutter rest is provided with a groove, and the cutter row is arranged in the groove; the tool rest is provided with a rotating shaft which vertically penetrates through two side surfaces of the groove, two ends of the rotating shaft are provided with limiting blocks, and the tool row is arranged on the rotating shaft; the tool rest is provided with a positioning and pressing device, the tool row is fixedly locked by the positioning and pressing device, and the tool rest is fixed on the lathe.

Preferably, the positioning and pressing device comprises a screw rod, a sliding plate, a pressing plate and a spring, the bottom end of the screw rod is rotatably connected to the sliding plate through a bearing, and the sliding plate is connected with the pressing plate through the spring.

Preferably, the side surfaces of the groove are provided with a positioning hole and a sliding groove in pair, the positioning hole is a threaded hole and is matched with the screw rod, and the sliding plate is arranged in the sliding groove.

Preferably, the bottom surface of the pressing plate is provided with a rubber bulge.

Preferably, the blade is fixed in the pressure groove through a screw.

In order to achieve the purpose, the novel technical scheme is as follows:

this neotype beneficial effect lies in:

1. through all setting up the indent at the anterior segment of sword row and back end, can install two blades on every sword row, when one of them blade wearing and tearing, can be through rotating the pivot, with another blade to the front end use.

2. This neotype blade passes through in the fix with screw indent, when the blade wearing and tearing, can unpack apart the screw, changes a blade, just so can not waste the tool row.

3. Through setting up location closing device, fix the tool row in the knife-loading frame, promote the slide through twisting the screw rod and drive the pressure strip and carry out spacing fixed to the tool row to make the pressure strip firm tightly on the tool row of supporting under the elastic action of spring, make the tool operation stable.

4. The bottom surface through the pressure strip sets up the rubber arch for area of contact between pressure strip and the tool gang is bigger, compresses tightly more reliably, and simultaneously, rubber is the elastic component, is difficult to damage the tool gang.

Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 to 3, the improved cutting tool for a lathe provided by the utility model comprises a blade 10, a tool row 20 and a tool rest 30, wherein both the front section and the rear section of the tool row 20 are provided with press grooves, the blade 10 is arranged in the press groove, the tool rest 30 is provided with a groove 40, and the tool row 20 is arranged in the groove 40; a rotating shaft 50 is arranged on the tool rest 30, the rotating shaft 50 vertically penetrates through two side surfaces of the groove 40, two ends of the rotating shaft 50 are provided with limiting blocks 60, and the tool row 20 is arranged on the rotating shaft 50; the tool rest 30 is provided with a positioning and pressing device 70, the tool row 20 is fixedly locked by the positioning and pressing device 70, and the tool rest 30 is fixed on a lathe.

By providing the indent at both the front and rear sections of the blade row 20, two blades 10 can be mounted on each blade row 20, and when one of the blades 10 is worn, the other blade 10 can be rotated to the front end for use by rotating the rotating shaft 50.

Specifically, the positioning and pressing device 70 comprises a screw 71, a sliding plate 72, a pressing plate 73 and a spring 74, wherein the bottom end of the screw 71 is rotatably connected to the sliding plate 72 through a bearing 75, and the sliding plate 72 is connected to the pressing plate 73 through the spring 74. The side surfaces of the groove 40 are provided with a positioning hole 80 and a sliding groove 90 in pair, the positioning hole 80 is a threaded hole and is matched with the screw rod 71, and the sliding plate is arranged in the sliding groove 90.

The cutter row 20 is fixed in the cutter installing frame 30 by arranging the positioning pressing device 70, the sliding plate 72 is pushed by screwing the screw 71 to drive the pressing plate 73 to limit and fix the cutter row 20, and the pressing plate 73 is firmly abutted against the cutter row 20 under the elastic action of the spring 74, so that the cutter operates stably.

Specifically, a rubber protrusion 76 may be optionally provided on the bottom surface of the pressing plate 73. Of course, the rubber protrusion 76 may not be provided. The rubber bulge 76 is arranged on the bottom surface of the pressing plate 73, so that the contact area between the pressing plate 73 and the cutter row 20 is larger, the pressing is more reliable, and meanwhile, the rubber is an elastic part and is not easy to damage the cutter row 20.

Specifically, the insert 10 is secured in the indent by a screw 100. The novel blade 10 is fixed in the pressure groove through the screw 100, when the blade 10 is worn, the screw 100 can be disassembled, and one blade 10 is replaced, so that the tool row 20 cannot be wasted.
