Description

Axial floating forward deburring cutter

Technical Field

The utility model relates to a deburring cutter, more specifically says, it relates to an axial unsteady forward deburring cutter.

Background

Most of the deburring processing technologies in the traditional industrial field adopt manual operation, deburring processing is carried out by means of a handheld pneumatic or electric tool, the processing methods are generally low in efficiency, the reject ratio of products is easily increased, and therefore, some manufacturers begin to use robots to install electric or pneumatic tools for automatic deburring processing.

Compared with manual operation, the robot deburring device can effectively reduce labor cost and improve production efficiency, but in the deburring process of complex workpieces, when the rigid deburring tool is used for processing burrs of the workpieces with irregular shapes such as edges, corners and crossed holes, the situations of cutter breakage or damage to the workpieces easily occur.

In the casting process of metal parts by the prior deburring technology, for the same type of workpieces, burrs generated on the same position of different individuals are different in length, and when the burrs on one workpiece are removed and the burrs of the other workpiece are removed by the same cutting force, if the cutting force is too small, incomplete removal is possible; if the cutting force is too large, the workpiece may be scrapped. And for the cast member profile burr, if the burr is removed by a rigid cutter, the appearance of the part is different due to different blank allowance, and the appearance attractiveness of the part is influenced.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide an axial floating forward deburring sword has the effect of guaranteeing the part aesthetic property.

In order to achieve the technical purpose, the utility model provides a following technical scheme: the utility model provides an axial floating forward deburring cutter, includes cylindric shell, the one end of shell is inserted and is equipped with the guide post, the external diameter of guide post is less than the internal diameter of shell inner chamber, the one end threaded connection that the shell inserted the guide post has the screw cap, the vertical extension of one end that the guide post deviates from the shell has the post that floats, screw cap central authorities offer the centre bore that supplies the post that floats to pass, the diameter of centre bore is greater than the diameter of the post that floats, the diameter of centre bore is less than the diameter of guide post, the other end of shell extends has the fixed cover of internal thread, fixed cover interpolation is equipped with compression spring, fixed cover internal thread connection has interior hexagonal screw, compression spring is located between interior hexagonal screw and the guide post.

Through adopting above-mentioned technical scheme, insert the shell with the guide post earlier, with screw cap screw in shell, fill in compression spring and screw hexagon socket head cap screw, push up the guide post with the help of compression spring, fix the cutter arbor at the post tip that floats, fix the shell on the lathe again, when carrying out burring operation to the part, the space in post and the centre bore that floats can supply the post to float to rock, when meetting the irregular surface of part, can pass through compression spring, the automatic adjustment main shaft swing angle that floats, thereby drive the cutter and make 360 degrees floating motions along with irregular work piece profile, thereby can very easily and can more thoroughly clear away the burr of each position of irregular work piece, the pleasing to the eye degree of part has been improved. The deburring of floating can be realized only by the cooperation of the compression spring and the guide post, the processing difficulty is reduced, and the processing cost is reduced.

Preferably, the center of one end of the guide post inserted into the shell is connected with a limit screw in a threaded manner, the limit screw is concentric with the guide post, and the compression spring is sleeved outside the limit screw.

Through adopting above-mentioned technical scheme, limiting screw plays the guide effect to compression spring, guarantees that compression spring can only keep concentric state with the guide post, avoids compression spring skew to guide post one side, makes the unable normal return of guide post, influences the normal work of deburring sword, has improved the rationality of structure.

Preferably, an ER11 nut is screwed on the end of the floating column, and a recess for inserting the end of the cutter bar is opened on the end of the floating column.

Through adopting above-mentioned technical scheme, after the tip of cutter arbor inserted the pit of unsteady post, the nut is screwed, can fix the cutter arbor on the unsteady post, when needing to take off the bush-cutter, unscrew ER11 nut just can, improved the simple operation nature.

Preferably, the diameter of the inner hole of the fixing sleeve is smaller than the outer diameter of the guide post.

Through adopting above-mentioned technical scheme, the guide post can't insert in the fixed cover, avoids the guide post to receive the fixed cover of compressing back of part, influences the normal work of deburring sword.

To sum up, the utility model discloses following effect has been gained:

1. by means of the cooperation of guide post, screw cap and compression spring, realized floating the burring, promoted the pleasing to the eye degree of part.

In the figure, 1, a housing; 2. a guide post; 3. a threaded cap; 4. a floating column; 5. a central bore; 6. fixing a sleeve; 7. a compression spring; 8. a hexagon socket head cap screw; 9. a limiting screw; 10. ER11 nut.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.

Example (b): the utility model provides an axial positive going unhairing bayonet, as shown in fig. 1 and 2, including cylindric shell 1, the one end of shell 1 is inserted and is equipped with guide post 2, the external diameter of guide post 2 is less than the internal diameter of shell 1 inner chamber, the one end threaded connection that shell 1 inserted guide post 2 has screw cap 3, the vertical extension of the one end that guide post 2 deviates from shell 1 has

unsteady post

4, 3 central authorities of screw cap offer the centre bore 5 that supplies unsteady post 4 to pass, the diameter of centre bore 5 is greater than the diameter of unsteady post 4, the diameter of centre bore 5 is less than the diameter of guide post 2, the other end of shell 1 extends has the fixed cover 6 of internal thread, fixed cover 6 interpolation is equipped with compression spring 7, fixed cover 6 internal thread connection has hexagon socket head cap screw 8, compression spring 7 is located between hexagon socket head screw 8 and.

Insert guide post 2 into shell 1 earlier, with screw cap 3 screw in shell 1, pack in compression spring 7 and screw hexagon socket head cap screw 8, push up guide post 2 with the help of compression spring 7, fix the cutter arbor at 4 tip of post that floats, fix shell 1 on the lathe again, when carrying out burring operation to the part, the post 4 that floats can supply post 4 to rock in the space of post 4 and central hole 5 that floats, when meetting the irregular surface of part, can pass through compression spring 7, the automatic adjustment main shaft swing angle that floats, thereby drive the cutter and make 360 degrees floating motions along with irregular work piece profile, thereby can very easily and can more thoroughly clear away the burr of each position of irregular work piece, the pleasing to the eye degree of part has been improved.
