Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a deburring mechanism for punching processing of precision stamping parts comprises a side column 1, an electric push rod 2, a support rod 3, a groove 4, a cross rod 5, a hydraulic column 6, a grabbing rod 7, a slide rail 8, a belt 9, a telescopic rod 10, a motor 11, a rotating shaft 12, a fixing column 13, a sand sheet 14, a clamping rod 15 and a baffle 16, wherein the electric push rod 2 is arranged inside the side column 1, the support rod 3 is fixed on the upper surface of the electric push rod 2, the support rod 3 is arranged inside the side column 1, the groove 4 is formed in the upper end of the side surface of the support rod 3, the cross rod 5 is connected inside the groove 4, the hydraulic column 6 is fixed below the cross rod 5, the hydraulic column 6 is arranged at the center position of the cross rod 5, the grabbing rod 7 is connected to the front end of the hydraulic column 6, the slide rail 8 is arranged inside the side column 1, the belt 9 is arranged inside the side column 1, the telescopic rod 10 is fixed above the electric push rod, a rotating shaft 12 is connected above the motor 11, a fixing column 13 is arranged on the side surface of the rotating shaft 12, an abrasive sheet 14 is connected inside the fixing column 13, a clamping rod 15 is fixed inside the side column 1, and a baffle 16 is arranged on the surface of the belt 9.

Electric putter

2 and 3 symmetries of bracing piece are provided with 4, and the rear side of 2 bracing pieces 3 in back is opened and is equipped with the hole, and the rear of bracing piece 3 corresponds the position and is provided with electric putter 2, and inside electric putter 2 can stretch out and draw back to bracing piece 3, the dismantlement and the burring of work piece were gone on in the position of difference, so remove the work piece, need remove horizontal pole 5, and the reciprocating of horizontal pole 5 and the stability of burring need electric putter 2 and bracing piece 3 to cooperate going on.

Recess 4 and horizontal pole 5 are connected for the block, and kelly 15 carries on spacingly to horizontal pole 5 sets up to the I shape, when carrying out the burring, horizontal pole 5 is fixed by recess 4 and kelly 15 all around, and 5 both sides of horizontal pole are also spacing by slide 8, guarantee the stability of horizontal pole 5 when the burring.

Hydraulic pressure post 6 constitutes extending structure with snatch pole 7, and snatch 7 symmetries and set up 4 to the front end that snatchs pole 7 sets up to semi-circular, and when the work piece was installed again, opens earlier and snatchs pole 7, under hydraulic pressure post 6 effect, snatchs pole 7 and contracts, and the semi-circular work piece that can fix effectively of snatching pole 7, thereby removes and the burring.

Slide 8 and horizontal pole 5 are sliding connection, and slide 8 is provided with 2 to slide 8 shape is "U" type, and slide 8 is spacing to horizontal pole 5, has guaranteed that horizontal pole 5 when removing, can not both ends length difference, causes the centre of a circle of work piece and the 12 centre of a circle of axis of rotation different, causes the burring incomplete.

Telescopic link 10 and axis of rotation 12 are connected for the block, and the two constitutes rotating-structure, axis of rotation 12 drives fixed column 13 and rotates when the burring, thereby drive abrasive disc 14 and rotate, come to rub the burr, when telescopic link 10 reciprocated, because telescopic link 10 and axis of rotation 12 enclose the block connection, so can not arouse droing of axis of rotation 12, and fixed column 13's inside is provided with the spring, when the rotational speed is low or the device stopped operation, can follow the work piece with axis of rotation 12 inside and take out, and do not cause the influence to the secondary use.

The working principle is as follows: when the deburring mechanism for punching and processing the precision stamping part is used, a workpiece is clamped behind a side column 1 through a hydraulic column 6 and a grabbing rod 7, then a supporting rod 3 is lifted through an electric push rod 2, a cross rod 5 in a groove 4 of the supporting rod 3 is driven to lift, the workpiece is also driven to lift, after the highest point is reached, the electric push rod 2 stops, the electric push rod 2 behind the supporting rod 3 extends out, the cross rod 5 is pushed onto a belt 9 and moves leftwards under the driving of the belt 9, a baffle 16 is arranged on the upper surface of the belt 9 and can push the cross rod 5, the cross rod 5 can continue to move leftwards and is connected with the groove 4 of the supporting rod 3 on the left side, and the cross rod 5 can descend under the action of the electric push rod 2 and then stops after descending to a certain position;

after horizontal pole 5 stops, telescopic link 10 rises, in exploring hole with sand piece 14 and fixed column 13, open motor 11, drive axis of rotation 12 and rotate, thereby drive fixed column 13 and sand piece 14 and rotate, under centrifugal force, sand piece 14 and downthehole wall rub, thereby burring, because work piece and sand piece 14 rub, so drive horizontal pole 5 shake, and slide 8 on horizontal pole 5 left and right sides, the stability of work piece can all be kept to the kelly 15 at recess 4 and horizontal pole 5 rear, after having gone the burr, the work piece falls on belt 9 again, transport the rear, carry out the dismantlement installation of work piece, holistic practicality has been increased.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
