Description

Cutter for efficiently removing burrs of cross apertures of automobile parts

Technical Field

The invention relates to a cutter for processing cross apertures, in particular to a cutter for efficiently removing burrs of cross apertures of automobile parts.

Background

In the machining process of automobile parts, cross hole parts are often encountered, and the problem of burr flanging commonly exists at the cross hole. The cross aperture is used as a connecting hole for liquid circulation such as a water path, an oil path and the like, so that no removable burr exists, and the machined product needs to be deburred. At present generally rely on artifical manual getting rid of, often can appear the burr and do not get the phenomenon of net, hourglass getting, carry and do not use manual getting to the harder product of material, inefficiency, deburring is inhomogeneous, influences the product quality.

If the flanging is carried out on the straight plane, a chamfering cutter can be additionally arranged on the existing processing equipment, burrs are removed through the chamfering cutter, but if the flanging is carried out on an irregular curved edge opening (such as a crossed hole), the flanging can not be processed on common processing equipment, and only the burrs can be manually removed after the product is processed, so that the labor is wasted, and the production efficiency is low.

Disclosure of Invention

The invention aims to solve the problems and provide a tool for efficiently removing burrs of cross apertures of automobile parts.

The purpose of the invention is realized by the following technical scheme:

the utility model provides a cutter of automobile parts cross aperture burr is got rid of to high efficiency, includes handle of a knife and cutter arbor, the cutter arbor pass through the drive connecting piece and install in the lower part of handle of a knife, the cutter arbor be cylindrical stock, the rectangular fluting is seted up to the cutter arbor, installation elastic component in the fluting, the bottom perpendicular to fluting both sides of cutter arbor are equipped with the round hole, pass round hole and fluting installation pivot, installation swing blade on the pivot, swing blade go on under the effect of pivot and elastic component about or inside and outside the activity.

The swinging blade is a copper thin rod and is positioned in the slot, one end of the swinging blade is sleeved on the shaft pin, and the other end of the swinging blade protrudes out of the slot.

And a clamping plate is arranged in the groove and fixes the elastic piece and the shaft pin.

The upper end of the clamping plate is fixedly connected to the cutter bar through a screw.

The elastic piece is a compressed spring.

The grooving on the cutter arbor equals with cutter arbor length, and grooved width is 1 with cutter arbor diameter ratio: 2-3, the ratio of the depth of the groove to the diameter of the cutter bar is 2: 3-4.

When the tool is used, the tool is arranged on a machining center, the machining center drives and controls the tool to act, the tool bar penetrates through a cross hole, the swinging blade can move up and down or inside and outside, the curved edge of the cross hole is an irregular ellipse, the rigidity of the tool is utilized, the resistance of the tool to the machining allowance of a machining part is controlled through the feeding amount of equipment, the chamfer angles of the tool during machining are different in size, and have offset, so that the machining tool swings, the tool recedes backwards, the tool feeds upwards in a small-allowance place, the function of removing flanging burrs is achieved, the sizes of the removed parts are consistent, and the burrs can be effectively removed.

Compared with the prior art, the invention has the beneficial effects that: the invention provides a cutter for efficiently removing burrs of cross apertures of automobile parts, and a swing blade arranged in the cutter can be stretched up and down and inside and outside according to the shape of a cross hole in the use process, chamfers can be machined at the edges of irregular cross holes, the chamfers of machined products are basically consistent, and batch numerical control machining is realized.

Detailed Description

The invention is described in detail below with reference to the figures and specific embodiments.

Example 1

The utility model provides a cutter of high-efficient auto parts cross aperture burr of getting rid of, as shown in fig. 1-3, including handle of a knife c and cutter arbor an, cutter arbor a installs in the lower part of handle of a knife c through drive connecting piece b, cutter arbor a is cylindrical stock, cutter arbor a sets up rectangular fluting 1, installation elastic component 3 in the fluting 1, the bottom of cutter arbor a is perpendicular to fluting 1 both sides and is equipped with round hole 5, pass round hole 5 and fluting 1 installation pivot 4, install swing blade 6 on the pivot 4, swing blade 6 carries out up-and-down or inside and outside activity under the effect of pivot 4 and elastic component 3, swing blade 6 is the thin stick of copper, swing blade 6 is located fluting 1, a pot head is established on pivot 4, the other end stretches out fluting. Be equipped with cardboard 2 in fluting 1, cardboard 2 is fixed with elastic component 3 and pivot 4, and screw fixed connection is passed through in cutter arbor an in 2 upper ends of cardboard, and elastic component 3 is the spring of compression, and fluting 1 on the cutter arbor an equals with cutter arbor an length, and the width and the cutter arbor diameter ratio of fluting 1 are 1: 2-3, this example is specifically 1: 2, the ratio of the depth of the groove to the diameter of the cutter bar is 2: 3-4, this example is specifically 2: 3.
