Abstract
The utility model relates to a handheld pneumatic type deburring tool of a cross-hoe penetrating portion. The handheld pneumatic type deburring tool comprises a pneumatic driving device, wherein a knife rod is arranged at an output end of the pneumatic driving device, a connecting end and a transmission end are arranged on the knife rod, a knife blade is connected to the transmission end of the knife rod, a force application spring is arranged between the knife blade and the output end of the pneumatic driving device, and a limit bayonet lock is arranged at the transmission end at the front end of the knife blade. According to the handheld pneumatic type deburring tool of the cross-hoe penetrating portion, the knife blade is stable in motion and little in vibration, and enables a chamfer on the penetrating portion to be uniform and smooth.
Description
Technical field
The utility model relates to a kind of machining aid, is specifically related to a kind of deburring tool.
Background technology
Large-scale engineering machinery mission case part, a lot of minor diameter high pressure oilholes and major diameter closed hole and cross-distribution are arranged on it, and its intersection belongs to space curve, requires to remove crossover sites burr and can not injure aperture and closed hole inwall, the impact sealing, deburring is very difficult.
Existing a kind of deburrer, its material is high-speed steel, the long 200mm of cutter, wide 25mm, thickness 5mm, rake face and rear knife face angle are 45 °, anterior angle equates that with relief angle cutting edge inclination is 20 °.Adopt the mode of artificial scraping to remove burr.It is high that to be artificial scraping require workman's technical merit weak point, and operation intensity is large, and production efficiency is low, and for the large hole of the degree of depth, the operation visual field is little, artificial more difficult grasp cutter, and poor removal effect with aperture and the scratch of closed hole inwall, causes part to be scrapped easily.
Summary of the invention
Goal of the invention: the purpose of this utility model is in order to overcome deficiency of the prior art, to provide a kind of blade movement steady, shakes littlely, passes through mutually the position deburring tool so that pass through mutually the uniform and smooth hand-held pneumatic formula cross bore of position chamfering.
Technical scheme: in order to solve the problems of the technologies described above, a kind of hand-held pneumatic formula cross bore described in the utility model is passed through the position deburring tool mutually, it comprises pneumatic actuating device, output at described pneumatic actuating device is provided with knife bar, be provided with link and driving end at described knife bar, blade is connected on the driving end of described knife bar, is provided with force application spring between the output of described blade and pneumatic actuating device, is provided with spacing bayonet lock at the driving end of described blade front end.
The two ends of described blade are blade, and they are symmetrical, and angle is 110 °.
Described blade is the high-speed steel blade.
Described force application spring is cylindroid helical-coil compression spring.
Described knife bar is uploaded the both sides, moved end and is milled with the plane.
When the utility model uses, handheld tool gos deep in the closed hole, blade is placed the aperture, contact with the cross bore intersection at force application spring effect bottom knife two-edged, the contact force size is determined by force application spring, two contact points coexist the vertical-transmission bearing pin to the plane in, blade is rotatable under the pneumatic actuator effect, under the force application spring effect, can move back and forth, the blade smooth running shakes littlely, and any point forms the space curve identical with the intersection shape on the cutting edge, the burr and the sharp edge that pass through mutually the position can be removed, form smooth geometrical property.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: the utility model has improved the deburring quality, has reduced operation requirements, has improved production efficiency.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Such as Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, a kind of hand-held pneumatic formula cross bore described in the utility model is passed through the position deburring tool mutually, it comprises pneumatic actuating device 1, output at described pneumatic actuating device (1) is provided with knife bar (2), be provided with link (3) and driving end (4) at described knife bar (2), blade (5) is connected on the driving end (4) of described knife bar (2), between the output of described blade (5) and pneumatic actuating device (1), be provided with force application spring (6), be provided with spacing bayonet lock (7) at the driving end (4) of described blade (5) front end.The two ends of described blade (5) are blade (8), and they are symmetrical, and angle is 110 °; Described blade (5) is the high-speed steel blade; Described force application spring (6) is cylindroid helical-coil compression spring; Described knife bar (2) is uploaded both sides, moved end (4) and is milled with plane (9).The anterior angle of blade described in the utility model is 2 °, and relief angle is 20 °, and blade is installed before the force application spring, and holddown spring, mounting limit bayonet lock before the blade, and the unit head of pneumatic actuating device is vertical with handheld terminal.When the utility model uses, handheld tool gos deep in the closed hole, blade is placed the aperture, contact with the cross bore intersection at force application spring effect bottom knife two-edged, the contact force size is determined by force application spring, two contact points coexist the vertical-transmission bearing pin to the plane in, blade is rotatable under the pneumatic actuator effect, under the force application spring effect, can move back and forth, the blade smooth running shakes littlely, and any point forms the space curve identical with the intersection shape on the cutting edge, the burr and the sharp edge that pass through mutually the position can be removed, form smooth geometrical property.The utility model moves back and forth motion by the blade rotation, and blade movement is steady, shakes little, so that it is uniform and smooth to pass through mutually the position chamfering, improved the deburring quality, by the hand-held pneumatic formula, alleviate workman's operation intensity, reduce the specification requirement to operation, improved production efficiency.
The utility model does not relate to partly all, and the prior art that maybe can adopt same as the prior art is realized.
