Description

Ball head disc brush

Technical Field

The present invention relates to a sanding tool, and more particularly, it relates to a ball-headed disc brush.

Background

The existing brush body for processing the metal grinding burrs of the back has the advantages that the brush body is used for increasing the hardness to achieve a good cleaning function, the brush rod of the brush body mainly adopts the brush rod with the silicon carbide content exceeding 70%, the brush rod is a high-hardness brush rod, and the brush body has good brushing performance on some harder burrs.

However, the brush rod is too brittle due to the excessive content of silicon carbide, and the brush rod is often broken after long-term use.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a spherical head disk brush, wherein when a spherical head performs brush body action, the spherical head is not easy to break through the elastic bending performance of an elastic rod, and the spherical head has higher hardness, so that the spherical head can clean harder burrs.

The technical purpose of the utility model is realized by the following technical scheme:

a ball head disc brush comprises a disc body, wherein a rotating shaft is fixed on the upper end face of the disc body, an elastic rod is fixed on the lower end face of the disc body, and the end part of the elastic rod is glued with a ball head with silicon carbide accounting for more than 70%.

By adopting the technical scheme, the spherical brush head is a high-hardness brush head, and the silicon carbide accounts for more than 70% of the spherical brush head, so that the spherical brush head has high hardness, and is not rod-shaped due to the spherical arrangement, so that the spherical brush head is not easy to break; and the silicon carbide is adhered to the spherical brush head through glue, so that the connection relationship between the spherical brush head and the silicon carbide is very firm.

The advantage of this design lies in adopting the elastic rod, and the elastic rod has the bending function, can stir back automatic re-setting, consequently meets during harder dirt at the clearance burr in-process of globular brush head, can make a round trip repeatedly stir globular brush head, and difficult emergence rupture, increase of service life by a wide margin.

Preferably, the resilient lever is a nylon lever.

Through adopting above-mentioned technical scheme, the nylon pole elasticity is comparatively excellent.

Preferably, the elastic rods are arranged on the disc body for 4 circles, and the 4 circles of elastic rods are arranged in concentric circles.

Through adopting above-mentioned technical scheme, 4 rings of elastic rod are densely arranged, are favorable to improving the effect of brush.

Preferably, the length of the elastic rod is 15-20 mm.

Through adopting above-mentioned technical scheme, the elastic rod overlength, when pushing down the disk body, the crooked deformation of elastic rod will be too big for interval grow between the adjacent elastic rod, the clearance of spherical brush head when cleaning is too big so, can lead to the incompleteness of cleaning.

The elastic rod is excessive to cause insufficient deformation for bending.

Therefore, through multiple tests, the length of the elastic rod in the design is controlled to be 15-20mm, the bending deformation of the elastic rod when the elastic rod is blocked can be met, and the deformation is not too large.

Preferably, one end of the elastic rod extending into the spherical brush head is provided with a supporting rod.

Through adopting above-mentioned technical scheme, branch is as the skeleton for the elastic rod that globular brush head is more firm is fixed, makes globular brush head be difficult to drop from branch.

Preferably, the struts and the resilient rods are arranged vertically.

Through adopting above-mentioned technical scheme, vertical arrangement is in order to avoid branch to extend excessively towards elastic rod length direction, because the friction surface that can make branch enter into spherical brush head because excessive extension, and when long-time the back of using, spherical brush head can wear and tear for branch also can wear and tear.

Therefore, the vertical arrangement can avoid the abrasion of the supporting rod and the spherical brush head together, so that the supporting rod can always keep good structural support between the elastic rod and the spherical brush head.

Preferably, the number of the struts is at least 2, and the struts are arranged at equal intervals along the circumferential direction of the elastic rod.

Through adopting above-mentioned technical scheme, increase the fastness that globular brush head and elastic rod are fixed.

Detailed Description

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

Embodiment 1, a ball head disc brush, referring to fig. 1 to 3, includes a disc body 1, the disc body 1 being a disc;

a rotating shaft 2 is fixed on the upper end face of the disc body 1, and the rotating shaft 2 is inserted into the disc body 1 and then fixed through glue; the rotating shaft 2 can be clamped by a pistol drill, and then the tray body 1 is driven by the pistol drill to rotate together;

an elastic rod 3 is fixed on the lower end face of the tray body 1, and the elastic rod 3 is a nylon rod.

The elastic rod 3 is inserted into the tray body 1 and then fixed by glue; the elastic rods 3 are arranged on the disc body 1 for 4 circles, and the 4 circles of elastic rods 3 are arranged in concentric circles. The length of the elastic rod 3 is 18 mm.

One end of the elastic rod 3, which is far away from the disk body 1, is glued with a spherical brush head 4 with more than 70 percent of silicon carbide, and the spherical brush head 4 is a brushing ball with silicon carbide powder fixed on the elastic rod 3 through glue.

The side of the spherical brush head 4, which is far away from the disc body 1, is spherical for friction.

The working principle is as follows: the pistol drill centre gripping pivot 2 drives disk body 1 and elastic rod 3 rotation, then the spherical brush head 4 is pressed at the friction surface back and forth movement, realizes polishing. Because the elastic rod 3 has bending deformation capacity, the elastic rod is not easy to break, and the hardness of the spherical brush head 4 is higher, the grinding work of harder burrs can be completed, and the service life of the disc brush can be effectively prolonged.

Embodiment 2 is a ball head disk brush, which is different from embodiment 1 in that, referring to fig. 4, an integrally formed support rod 5 is fixed to one end of an elastic rod 3 extending into a ball head 4.
