Description

Bench drill for processing section holes

Technical Field

The utility model relates to a mechanical auxiliary equipment technical field, more specifically say, it relates to a bench drill for section bar spot facing work.

Background

The bench drill is a drilling machine tool which has small volume and simple and convenient operation and is generally arranged on a workbench.

The traditional Chinese patent with the application number of CN201120417402.3 provides a bench drill, which comprises an upright post, wherein the top of the upright post is hinged with a cross rod, a drill bit is arranged on the cross rod towards the lower part, a connecting block, more than one U-shaped supporting plate and a base workbench are arranged below the upright post, the connecting block is fixedly connected with the bottom of the upright post, and the head and the tail of the U-shaped supporting plate are respectively fixedly connected with the connecting block and the base workbench; the operator places the profile on the table and drills a hole with the bench drill, and after drilling is completed, moves the profile to align with the next drilling point.

However, when the profile is cut by a drill, the position of the profile needs to be continuously changed to meet different drilling requirements, but the profile generally has high mass, so that the friction force between the profile and a workbench is high, and the profile is difficult to move by an operator, so that the improvement is needed.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a bench drill for section bar spot facing work, it has the advantage that the operating personnel of being convenient for removed the section bar on the workstation.

In order to achieve the above purpose, the utility model provides a following technical scheme:

the utility model provides a bench drill for section bar spot facing work, includes drill bit and workstation, the drill bit sets up the cutting area at the workstation, it puts the thing groove to have seted up a plurality ofly on the workstation, and is a plurality of put thing groove align to grid on the workstation, a plurality of put and place the rolling ball in the thing groove.

By adopting the technical scheme, when the section is cut by the drill bit, the position of the section needs to be continuously changed to meet different drilling requirements, but the section generally has higher mass, and an operator is difficult to move the section; therefore, the sectional material is placed on the workbench and is abutted against the surface of the rotating ball, when an operator moves the sectional material, the sliding friction between the sectional material and the workbench is converted into the rolling friction between the sectional material and the rotating ball through the rotation of the rotating ball in the article placing groove without dead angles, and the difficulty of moving the sectional material by the operator is reduced.

Further, the inner side wall of the storage groove is provided with a smooth layer, and the smooth layer is attached to the surface of the rotating ball.

Through adopting above-mentioned technical scheme, when the rolling ball when putting the thing inslot and roll with put thing groove inside wall and continuously rub, lead to the material wearing and tearing easily, the event is through the contact of smooth layer with the rolling ball, avoids the rolling ball and the direct contact who puts the thing groove inside wall, reduces the wearing and tearing to putting the thing groove inside wall.

Furthermore, the workbench is provided with an anti-abrasion ring at the position of the object placing groove, and the anti-abrasion ring is sleeved on the rotating ball.

Through adopting above-mentioned technical scheme, the section bar passes through the rolling ball and removes the in-process, rolls along the moving direction of section bar, and the opposition thing inslot lateral wall causes the extrusion, makes easily put the handing-over department of thing inslot lateral wall and workstation and produces the wearing and tearing piece, so injectd the position of rolling ball through preventing the grinding ring for the rolling ball is put the central point in thing groove and is put the rotation, reduces the wearing and tearing of material, has reduced the piece simultaneously and has fallen into and put the thing inslot.

Further, a limiting ring is arranged on the anti-abrasion ring, the limiting ring is sleeved on the rotating ball, and the inner side wall of the limiting ring is attached to the surface of the rotating ball.

Through adopting above-mentioned technical scheme, the drill bit is at the during operation, and the workstation takes place vibrations, and the rotatable ball is deviate from easily in vibrations and puts the thing groove, and the event is through the spacing ring for the rotatable ball is in and puts the thing inslot, is difficult to deviate from.

Further, threaded connection is arranged between the anti-abrasion ring and the workbench.

Through adopting above-mentioned technical scheme, the drill bit produces more tiny piece when driling to the section bar, gets into easily and puts the thing inslot, leads to mingling with more impurity between smooth layer and the rolling ball, influences the rotation of rolling ball, so need regularly prevent that the grinding ring is twisted out from the workstation to take out the rolling ball, thereby clean putting the thing groove, keep putting the clean in the thing groove.

Furthermore, a rotating groove is formed in the side wall of the outer edge of the anti-abrasion ring.

Through adopting above-mentioned technical scheme, when the abrasionproof circle is unscrewed to putting the thing groove and clearing up, rotate the groove and make operating personnel and the increase of the area of contact of wearing ring to be convenient for twist and move the wearing ring.

Furthermore, the end wall of the anti-abrasion ring close to the direction of the workbench is provided with a pressing pad, and the pressing pad is attached to the surface of the workbench.

Through adopting above-mentioned technical scheme, for further reducing the dust piece and entering into through the clearance between wear ring and the workstation and putting the thing inslot, through the elastic deformation who presses the pressure pad, improve the leakproofness between wear ring and the workstation.

Further, the joint of the side wall and the end wall of the anti-abrasion ring is arc-shaped.

By adopting the technical scheme, the joint of the side wall and the end wall of the anti-abrasion ring is in an arc shape, so that the phenomenon that an operator is scratched when touching the anti-abrasion ring when moving the sectional material is reduced.

To sum up, the utility model discloses following beneficial effect has:

1. the sliding friction between the section bar and the workbench is converted into the rolling friction between the section bar and the rotating ball by arranging the object placing groove on the workbench and placing the rotating ball in the object placing groove, so that the difficulty of moving the section bar by an operator is reduced;

2. the position of the rotating ball is limited through the anti-abrasion ring, so that the rotating ball rotates at the central position of the object placing groove, the abrasion of materials caused by the extrusion of the rotating ball to one side of the inner side wall of the object placing groove is reduced, and meanwhile, the phenomenon that chips fall into the object placing groove is reduced.
