Description

Cross bore oral area burr remover

Technical field

The utility model relates to field of machining, specifically is a kind of cross bore oral area burr remover that is used for removing the burr of all kinds of crossover sites in the residual cross bore of machining process.

Background technology

At present, in machining industry for institute's product processed in process, ubiquity the phenomenon of residual burr, this not only influences the outward appearance of product, in use also exist certain potential safety hazard, therefore after machining, also need it is handled.When especially workpiece inside has cross bore, its intersection ubiquity burr.Usually the processing workman in the factory all adopts instruments such as file or burr cutter to stretch into the interior burr removal with its infall of cross bore, and still, this method is removed burr and had following shortcoming:

1) file or burr cutter only have good operability to the burr at product edge position, also there is certain degree of difficulty in removal for the residual burr of two cross bore crossover sites, the operation of this deburring is generally operated by instruments such as hand-held file of workman or burr cuttves, but be difficult to remove the burr at this position clean, therefore, greatly reduce operating efficiency.

2) in addition, sharp-pointed file or burring knife be other positions of scratch product very likely, and if work the time overexert, the operator tends to be scratched by the sharp-pointed blade of instrument, therefore, this operation hidden danger to operator's security presence.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of and can remove the burr of cross bore oral area position and the cross bore oral area burr remover that can increase work efficiency greatly neatly.

For solving the problems of the technologies described above, the cross bore oral area burr remover that the utility model provides, it comprises location-plate, motor, drill point and cutter, described motor is connected on the location-plate, described drill point one end is connected with the output shaft of motor, and the other end is connected with cutter; Described cutter has the working position of radiused edges.

Described cutter comprises knife bar, blade, pin, spring and adjustment screw; Wherein, described blade is connected in the knife bar, and the afterbody and the pin of blade push against, and an end and the pin of described spring push against, and the other end pushes against with adjusting screw, and described adjustment screw threads is combined in the afterbody of knife bar.

Described knife bar front end has an axial pass trough, and the length of axial pass trough all matches with blade with width; Knife bar also tight fit has radially backing pin, and described radially backing pin is positioned at the rear portion of groove; Described blade also has stopper slot and cutter tail, and the contact of described cutter tail and pin is connected, and blade is by stopper slot and cooperating in the axial pass trough that is rotatably connected on knife bar of backing pin radially.

After adopting above structure, the utility model compared with prior art has the following advantages:

1) owing to the cutter with deburring is connected on the motor, to stretch in the hole and rotation removal burr by cutter, the man-hour of its deburring is short, has improved operating efficiency greatly.

2) in addition, the utility model is that the circular arc working position by cutter comes to remove intersecting the burr in aperture, both has been difficult for the scratch product surface, also is difficult for scratching the operator, has improved the security of using greatly.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.

By the structural representation of workpiece shown in Figure 1 as can be known, workpiece 5 inside have the endoporus that intersects anyhow, locate jagged residual position in two apertures that intersect endoporus, need carry out deburring and handle.

By the structural representation of the utility model cross bore oral area burr remover shown in Figure 2 as can be known, it comprises location-plate 1, motor 4, drill point 3 and cutter 2, described motor 4 is connected on the location-plate 1, described drill point 3 one ends are connected with the output shaft of motor 4, and the other end is connected with cutter 2; Described cutter 2 has the working position 211 of radiused edges.

By the structural representation of cutter in the utility model of Fig. 3～shown in Figure 6 as can be known, described cutter 2 comprises knife bar 26, blade 21, pin 23, spring 24 and adjusts screw 25 (adjust screw 25 in the present embodiment and be soket head cap screw).Wherein, described blade 21 is connected in the knife bar 26, and the afterbody of blade 21 and pin 23 push against.One end and the pin 23 of described spring 24 push against, and the other end pushes against with adjusting screw 25, and described adjustment screw 25 screws in the afterbody of knife bar 26.

Described knife bar 26 front ends have an axial pass trough 27, and the length of axial pass trough 27 all matches with blade 21 with width.Knife bar 26 also tight fit has radially backing pin 22, and described radially backing pin 22 is positioned at the rear portion of groove 27.Described blade 21 also has stopper slot 212 and cutter tail 213, and 23 contacts of described cutter tail 213 and pin are connected, and blade 21 is by stopper slot 212 and cooperating in the axial pass trough 212 that is rotatably connected on knife bar 26 of backing pin 22 radially.In other words, stopper slot 212 and cooperating of backing pin 22 radially, its main purpose be for blade 21 have one well fixing and spacing, blade 21 is not dropped in the course of the work.Cutter tail 213 adopts the design of approximate swallow-tail form, and is in contact with it the head employing conical design of the pin 23 of cooperation, under the acting in conjunction of dovetail and taper, can play blade 21 afterbodys are carried out spacing effect.In conjunction with the spring 24 at pin 23 rear portions, utilize the elasticity of spring again, make blade 21 in groove 27, have the trend of side-to-side movement.Described working position 211 is a radiused edges.Sharp-pointed shape cutting edge is not made in this position as existing cutter in the market, but utilizes the edge of itself that burr is removed, and has improved the security of using greatly.

By the course of action schematic diagram of the utility model cutter shown in Figure 7 and workpiece as can be known, after workpiece 5 is delivered to the cutter front end by the operator, continue firmly workpiece 5 to be advanced to the right (direction described herein is the direction shown in the accompanying drawing), this moment, blade 21 was stressed, the swallow-tail form inclined-plane at cutter tail 213 places is right sliding along the conical surface of pin 23 heads, pin 23 is promoted to the right, and Rear springs 24 is subjected to force compresses.At this moment, the working position 211 of blade 21 moves downward, workpiece 5 is passed through smoothly after, the working position 211 of blade 21 enters 6 places, the residual position of burr of workpiece 5.After cutter 2 entered, spring 24 did not restore to the original state because stress, and under the acting in conjunction of its anterior pin 23, blade 21 was resetted simultaneously.Because in whole course of action, all have motor 4 to drive cutters 2 and rotate, therefore, enter into the cross bore inside of workpiece 5 in the working position 211 of blade 21 after, by the rotation of blade 21 burr at 6 places, the residual position of burr is removed.The operator can adjust the compression stress of spring 24, to satisfy different process requirements by adjusting the degree of depth that soket head cap screw 25 is screwed into knife bar 26.

When cutter 2 is taken out from workpiece 5, workpiece 5 is withdrawed from left, this moment blade 21 working position 211 stressed pressing down, workpiece 5 can withdraw from from cutter 2 smoothly.
