Guide head

Abstract

The invention discloses a guide head. The guide head comprises a base, a fixing mechanism and a guide sleeve, wherein the base is fixedly connected with the fixing mechanism; the fixing mechanism comprises a fixed half hoop and a movable half hoop, wherein the fixed half hoop is in a U shape, comprises an arc-shaped part and extending parts arranged on the two sides of the arc-shaped part, limiting clamping grooves are formed in the extending parts, and the movable half hoop is in a C shape; the guide sleeve comprises a first cylinder body and a second cylinder body, wherein one end of the first cylinder body is fixed on the base, a through hole corresponding to the first cylinder body is formed in the base, a chip removal port is formed in an outer cylindrical surface of the first cylinder body, one end of the second cylinder body is provided with an external thread, and the other end of the second cylinder body is provided with an annular cover; and a bearing coaxial with the secondcylinder body is arranged inside the second cylinder body. The device can be adapted to and pass through pipelines or cylinders with various sizes; the guide head is of a split structure and is convenient to use; when drilling is carried out, the bearing rotates, the relative rotation speed of an inner ring of the bearing and a drill rod is reduced, and the friction force is reduced; and the guidehead is stable in positioning and suitable for various occasions.

Description

technical field [0001] The invention relates to the technical field of drilling auxiliary tools, in particular to a guide head suitable for drilling holes on pipes and cylinders. Background technique [0002] There are two types of drilling machines: seat type and hand-held. The seat type drilling machine can align the position where the building material needs to be drilled for fixed drilling. This type of drilling machine requires workers to drag the building material to the drill bit of the drilling machine , manpower consumption is serious, the cost is too high, and it is not very convenient to use. Hand-held drilling machines can be manually picked up and aligned with building materials to directly drill holes, but often because the drilling machine is easily affected by external factors, the drilling positioning is inaccurate or cannot be drilled vertically, resulting in low drilling accuracy and inability to The problem of meeting the process requirements, especially...

[0002] There are two types of drilling machines: seat type and hand-held. The seat type drilling machine can align the position where the building material needs to be drilled for fixed drilling. This type of drilling machine requires workers to drag the building material to the drill bit of the drilling machine , manpower consumption is serious, the cost is too high, and it is not very convenient to use

Hand-held drilling machines can be manually picked up and aligned with building materials to directly drill holes, but often because the drilling machine is easily affected by external factors, the drilling positioning is inaccurate or cannot be drilled vertically, resulting in low drilling accuracy and inability to The problem of meeting the process requirements, especially when it is necessary to drill holes on pipes or cylinders, the drill bit cannot be drilled vertically will cause the devices installed on the drill hole to be weak, and if the notification is not properly guided, the drill bit will also deviate, causing safety hazards
