Abstract

The utility model discloses a core drill positioner, including a locating pin, locating pin one end is toper, middle part for screw thread, the other end be four directions or hexagonal head, and the locating pin middle part is by lower to going respectively the suit a rubber pad, a gasket and a nut, and the gasket external diameter is less than the rubber pad external diameter by 20mm, and gasket thickness is 3 mm. Use the utility model discloses positioner can not bore the hole and damage inclined to one side or with the ceramic tile around the hole, and the trompil is efficient, the precision is high.

Description

Hollow drill positioning device

Technical Field

The utility model relates to a core drill positioner.

Background

In daily life and work, a hollow drill is often used for drilling holes or making holes on the existing wall and foundation. The hollow drill is difficult to position at the pre-opened hole and hole, the hole and the pre-opened position which are often opened always have deviation, and especially when the hole is formed in the wall surface pasted with the ceramic tile, the ceramic tile is very smooth, and the ceramic tile around the hole can be damaged. The impact rotor is added with the hollow rotor, and is long and heavy. During initial drilling, the ceramic tile is extremely easy to deviate and unsafe, the ceramic tile can be positioned only after going back and forth for several times, sometimes, the ceramic tile deviates from a preset position, and the surrounding ceramic tiles are damaged when the hollow drill deviates. The tapping efficiency is low, the precision is low, and the safety is poor.

Disclosure of Invention

An object of the utility model is to provide a core drill positioner can not bore the hole and bore inclined to one side or damage the ceramic tile around the hole, and trompil is efficient, the precision is high.

The positioning device for the hollow drill comprises a positioning pin, wherein one end of the positioning pin is conical, the middle of the positioning pin is threaded, the other end of the positioning pin is square or hexagonal, the middle of the positioning pin is sleeved with a rubber pad, a round gasket and a nut from bottom to top, the outer diameter of the round gasket is 20mm smaller than the outer diameter of the rubber pad, and the thickness of the round gasket is 3 mm.

When the positioning device is used, the center of the pre-drilled hole is determined, the hole is drilled by using impact drilling, the positioning device is wedged into the hole, and then the nut is tightened. At the moment, the hollow drill is sleeved on the rubber, and the switch of the drilling machine is opened, so that the hollow drill cannot be heard from running. And after the hollow drill enters the wall body by 20mm, the hollow drill is withdrawn, a spanner is sleeved at the tail end of the positioning pin, and the nut on the positioning pin is screwed, so that the positioning device can be withdrawn from the wall body. And then the subsequent drilling operation is carried out. The positioning device can drill holes in accurate positions, deviation cannot be caused, tiles around the holes cannot be damaged due to the swing of the hollow drill, the hollow drill does not swing up and down, left and right, and safety is guaranteed.

Drawings

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

Fig. 1 is a schematic view of the structure of the present invention.

Detailed Description

A positioning device for a hollow drill comprises a positioning pin 6, wherein the inner side end 7 of the positioning pin 6 is of a conical structure, the middle of the positioning pin is provided with a thread, the other end of the positioning pin is provided with a square or hexagonal head 5, the middle of the positioning pin 6 is sleeved with a rubber pad 1, a round gasket 2 and a nut 3 from bottom to top, the outer diameter of the round gasket 2 is 20mm smaller than that of the rubber pad 1, and the thickness of the round gasket 2 is 3 mm. When the positioning pin fixing device is used, the center of the pre-drilled hole is determined, the hole is drilled through impact drilling, the positioning pin 6 is wedged into the hole, and then the nut 3 is tightened to ensure that the positioning pin 6 is fixed relatively. At the moment, the hollow drill 4 is sleeved on the rubber pad 1, and the switch of the drilling machine is turned on, so that the hollow drill cannot run without hearing the calling mess. And after the hollow drill 4 enters the wall body by 20mm, the hollow drill is withdrawn, a spanner is sleeved at the tail end of the positioning pin 6, and the nut 3 on the positioning pin is screwed, so that the positioning device can be withdrawn from the wall body.

Claims

1.
