Technical Field

The utility model relates to a machining cutter relieving device, in particular to a cutter relieving device for a planing T-shaped groove, and belongs to the technical field of machinery.

Background

When the T-shaped groove is machined by utilizing the shaper B665, the cutter table structure of the shaper B665 is limited, so that the requirement of the shaper B on a cutter can not be met, the cutter can not be automatically lifted by the conventional cutter-relieving device, the machined surface is easily scratched, unqualified products are caused, manual cooperation is needed, the cutter leaves the machined surface, and the cutter is subjected to single-stroke machining, complex in operation and inconvenient to use.

Disclosure of Invention

The utility model aims to solve the technical problem of providing a cutter relieving device for planing a T-shaped groove aiming at the defects existing in the prior art.

In order to solve the technical problem, the utility model provides a cutter-retracting device for a planing T-shaped groove, which comprises a rubber wheel, a first pin shaft, a second pin shaft, a connecting plate, cutter holders, T-shaped cutters, cutter clamping columns, a movable baffle plate, push-pull pins, workpieces and cutter pressing screws, wherein the cutter holders are arranged in the cutter clamping columns of a planing machine along with the T-shaped cutters, the cutter holders and the connecting plate are connected into a whole through the second pin shaft, the connecting plate can swing around the second arc of the pin shaft, the rubber wheel is clamped on the two connecting plates through the first pin shaft and can flexibly rotate around the axis of the first pin shaft, and the T-shaped cutters and the cutter holders are fastened through the cutter pressing screws.

The knife clamping column is arranged on the movable baffle plate, and the movable baffle plate is arranged on the axial push-pull pin at the top; the movable baffle plate on the shaper can swing around the push-pull pin on the sliding pillow and tilt together with the T-shaped cutter to realize cutter relief.

The beneficial effects are that: the cutter relieving device can meet the cutter relieving requirement when the T-shaped groove is machined by the shaper, is simple and practical, is easy to manufacture, can realize repeated utilization, has low production cost and improves the production efficiency.

In the figure: 1. a rubber wheel; 2. a pin shaft I; 3. a second pin shaft; 4. a connecting plate; 5. a tool apron; 6. a T-shaped knife; 7. a knife clamping column; 8. a movable baffle; 9. pushing and pulling pins; 10. a workpiece; 11. and (5) pressing a cutter screw.

Detailed Description

The present utility model will be described in detail with reference to the accompanying drawings and examples.

As shown in fig. 1-3, the utility model provides a cutter-relieving device for planing a T-shaped groove, which comprises a rubber wheel 1, a first pin roll 2, a second pin roll 3, a connecting plate 4, a cutter holder 5, a T-shaped cutter 6, a cutter clamping column 7, a movable baffle 8, a push-pull pin 9, a workpiece 10 and a cutter pressing screw 11, wherein the cutter holder 5 is arranged in the cutter clamping column 7 of a squaring machine along with the T-shaped cutter 6, the cutter holder 5 and the connecting plate 4 are connected into a whole through the second pin roll 3, the connecting plate 4 can swing around the circular arc of the second pin roll 3, the rubber wheel 1 is clamped on the two connecting plates 4 through the first pin roll 2 and can flexibly rotate around the axis of the first pin roll 2, and the T-shaped cutter 6 and the cutter holder 5 are fastened through the cutter pressing screw 11 to prevent looseness; when the cutter is fed, the T-shaped cutter 6 cuts into a groove of the workpiece 10, the workpiece 10 is cut, the connecting plate 4 drives the rubber wheel 1 to swing backwards, the T-shaped cutter 6 is far away from the T-shaped cutter 6 and does not contact the workpiece, when the working stroke is finished, the T-shaped cutter 6 is far away from the workpiece 10, the rubber wheel 1 swings around the axis circular arc of the pin shaft 3 under the action of dead weight, the T-shaped cutter 6 is close to the T-shaped cutter 6 and leaves the workpiece 10, when the cutter is retracted, the rubber wheel 1 firstly contacts the workpiece 10 and rolls on the surface of the workpiece 10, and the machined surface cannot be scratched because the material selected by the roller 1 is a solid rubber wheel.

The cutter clamping column 7 is arranged on the movable baffle plate 8, and the movable baffle plate 8 is arranged on an axial push-pull pin 9 at the top; the movable baffle plate 8 on the shaper can swing around the push pin 9 on the sliding pillow, and inclines together with the T-shaped cutter 6, the T-shaped cutter 6 leaves the processed surface of the T-shaped groove of the workpiece 10, and retreats from the surface of the workpiece 10 along with the rubber wheel 1, so that the purpose of cutter yielding is achieved; after the return stroke is finished, the T-shaped cutter 6 leaves the workpiece 10, the T-shaped cutter 6, the rubber wheel 1 and the movable baffle plate 8 automatically fall under the action of dead weight, the initial position is restored, and the next feeding stroke can be restarted.

The above description is for the convenience of those skilled in the art to understand and use the utility model, and is not intended to limit the scope of the utility model, and on the basis of the technical solution of the utility model, those skilled in the art may make various modifications or variations without any inventive effort, which remain within the scope of the utility model.
