Description

Technical Field

[0001] This utility model relates to the field of machine tool processing auxiliary tooling technology, and in particular to a hole countersinking tooling for a magnetic base drill. Background Technology

[0002] A magnetic drill, also known as a magnetic power drill, magnetic iron drill, or magnetic base drill, is a portable power tool that uses electromagnetic attraction to fix itself to the surface of a steel structure for drilling and tapping operations. It belongs to the category of mechanical engineering industrial equipment. It is used in steel structure processing fields such as shipbuilding, bridge construction, subway construction, and mechanical equipment installation. The equipment consists of a drilling system and an electromagnetic attraction system. It utilizes an energized base coil to generate a vertical magnetic force that attracts the steel surface, and achieves precise drilling through a high-speed rotating drill bit.

[0003] Currently, when drilling large steel components, magnetic drills are typically used to drill holes, followed by the use of large-scale equipment (often with a million-level capacity) and extension rods to smooth the reverse side of the hole. This process is not only costly, but also requires multiple hoisting and clamping operations for the large steel components, resulting in high construction risks, long processing cycles, and low processing efficiency.

[0004] Therefore, this utility model proposes a hole countersinking tool for a magnetic base drill to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a hole countersinking tool for a magnetic drilling machine, which works with the magnetic drilling machine to perform the reverse hole surface flattening function after drilling steel components, thereby reducing equipment usage costs and construction risks, and shortening the processing cycle.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a hole countersinking tool for a magnetic drilling machine, the innovation of which lies in: including Taper shank sleeve for connecting magnetic drill bit equipment; An adjusting rod is used to adjust the axial length of the tooling, and the adjusting rod is coaxially and detachably connected to one end of the tapered shank sleeve; A connecting rod for mounting a cutting tool is coaxially and detachably connected to the end of the adjusting rod away from the tapered shank sleeve. A tool locking hole is provided on the side of the connecting rod away from the adjusting rod, and a cutting tool is movably inserted into the tool locking hole. A guide post is used for positioning the magnetic drill bit. The guide post is coaxially and detachably connected to the end of the connecting rod away from the adjusting rod, and fixes the tool in the locking hole.

[0007] Furthermore, the adjusting rod and the tapered shank sleeve, as well as the connecting rod and the adjusting rod, are all connected by threads.

[0008] Furthermore, a threaded section is coaxially provided on one side end face of the guide post. The threaded section is coaxially provided with the guide post and integrally formed. A threaded hole matching the threaded section is opened on the connecting rod. The threaded hole is connected to the locking hole. The threaded section of the guide post is threadedly connected in the threaded hole, and the end of the threaded section enters the locking hole and abuts against the side wall of the tool.

[0009] Furthermore, the sidewall of the guide post includes two oppositely arranged arc surfaces and two oppositely arranged planes, with the arc surfaces and planes spaced apart.

[0010] Furthermore, the connecting rod includes an expanded diameter section and a reduced diameter section that are coaxially arranged and integrally formed. The outer diameter of the reduced diameter section is smaller than the outer diameter of the expanded diameter section, and the locking hole is opened on the reduced diameter section.

[0011] Furthermore, the central axis of the locking hole is perpendicular to the central axis of the reduced diameter section.

[0012] The advantages of this utility model are: (1) The hole countersinking fixture of this utility model uses a tapered shank sleeve to connect to a magnetic drill, and the magnetic drill drives the fixture to rotate. By designing an adjustment rod, an appropriate length of adjustment rod can be selected according to the thickness of the steel component, so that the fixture can meet the process requirements of steel components of different sizes. The cutting tool is movably inserted into the locking hole of the connecting rod, and an appropriate cutting tool can be selected according to the process requirements, while facilitating the scraping operation of the lower surface of the drilled hole. By selecting a guide post that matches the diameter of the drilled hole, the guide post is inserted into the drilled hole to position the magnetic drill on the steel component, thereby improving the processing accuracy. Through the mutual cooperation of the tapered shank sleeve, adjustment rod, connecting rod, cutting tool and guide post, the fixture can cooperate with the magnetic drill to complete the scraping of the reverse surface of the steel component after drilling. The operation process does not require the steel component to be moved, which reduces the equipment use cost and construction risk, and shortens the processing cycle.

[0013] (2) The adjusting rod and the tapered sleeve, and the connecting rod and the adjusting rod of this utility model are all connected by threads, which makes the installation and disassembly operation convenient and automatically realizes the centering of the axis.

[0014] (3) The guide post of this utility model achieves a detachable connection with the connecting rod through the mutual cooperation of the threaded section and the threaded hole, and at the same time achieves the clamping and fixing of the tool.

[0015] (4) The guide post of this utility model utilizes two oppositely arranged arc surfaces. When using the tooling, select a guide post whose outer diameter of the arc surface matches the outer diameter of the drill hole on the steel component. By inserting the guide post into the drill hole, the magnetic base drill is positioned on the steel component. The two oppositely arranged planes make it convenient for the operator to apply force to tighten the guide post, thereby achieving the purpose of clamping the tool.

[0016] (5) The connecting rod of this utility model uses the expansion section to ensure its own structural strength, while the design of the reduction section makes it easier for the operator to observe the working state of the hole surface being scraped flat.

[0017] (6) The central axis of the locking hole of this utility model is perpendicular to the central axis of the reduced diameter section. After the tool is inserted into the locking hole, it is perpendicular to the central axis of the threaded section of the guide post, which is beneficial to the stability of tool clamping.

[0020] Figure 2 This is a schematic diagram of the working process of the hole countersinking tool of this utility model. Detailed Implementation

[0021] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0022] Example This embodiment provides a hole countersinking tool for a magnetic drilling machine, such as... Figure 1-2 As shown, it includes a tapered shank sleeve 11 for connecting a magnetic drill bit, an adjusting rod 12 for adjusting the axial length of the tooling, a connecting rod 13 for mounting the cutting tool, and a guide post 14 for positioning the magnetic drill bit.

[0023] The small end of the tapered shank sleeve 11 has a flat end block. The adjusting rod 12 is coaxially and detachably connected to the large end of the tapered shank sleeve 11. The connecting rod is coaxially and detachably connected to the end of the adjusting rod 12 away from the tapered shank sleeve 11. The side of the connecting rod 13 away from the adjusting rod 12 has a locking hole 131. A cutting tool 15 is movably inserted into the locking hole 131. The guide post 14 is coaxially and detachably connected to the end of the connecting rod 13 away from the adjusting rod 12 and fixes the cutting tool 15 in the locking hole 131.

[0024] In this embodiment, the adjusting rod 12 and the tapered shank sleeve 11, and the connecting rod 13 and the adjusting rod 12 are all connected by threads. One end of the adjusting rod 12 has a first threaded section coaxially, and the large end of the tapered shank sleeve 11 has a first threaded hole coaxially, with the first threaded section threaded into the first threaded hole. The other end of the adjusting rod has a second threaded hole coaxially, and one end of the connecting rod has a second threaded section coaxially, with the second threaded section threaded into the second threaded hole. This threaded connection method facilitates installation and disassembly, and automatically achieves axis alignment when connected.

[0025] A third threaded section is coaxially provided on one end face of the guide post 14. The third threaded section is coaxially arranged with the guide post 14 and integrally formed. A third threaded hole matching the third threaded section is opened on the connecting rod 13. The third threaded hole communicates with the locking hole 131. The third threaded section of the guide post 14 is threaded into the third threaded hole, and the end of the third threaded section enters the locking hole 131 and abuts against the side wall of the tool 15. Through the mutual cooperation of the third threaded section and the third threaded hole, the guide post 14 achieves a detachable connection with the connecting rod, and at the same time achieves the clamping and fixing of the tool 15.

[0026] In this embodiment, the sidewall of the guide post 14 includes two oppositely arranged arc surfaces 141 and two oppositely arranged planes 142, with the arc surfaces 141 and planes 142 spaced apart. When using the fixture, a guide post 14 with an outer diameter matching the outer diameter of the drill hole on the steel component is selected. By inserting the guide post 14 into the drill hole, the magnetic drill bit is positioned on the steel component. The two oppositely arranged planes 142 facilitate the operator's application of force to tighten the guide post 14, thereby clamping the tool 15.

[0027] In this embodiment, the connecting rod 13 includes an expanded diameter section and a reduced diameter section that are coaxially arranged and integrally formed. The outer diameter of the reduced diameter section is smaller than that of the expanded diameter section, and the locking hole 131 is formed on the reduced diameter section. The connecting rod utilizes the expanded diameter section to ensure its structural strength, while the reduced diameter section design facilitates the operator's observation of the hole surface smoothing operation. The central axis of the locking hole 131 is perpendicular to the central axis of the reduced diameter section. After the tool 15 is inserted into the locking hole 131, it is perpendicular to the central axis of the third threaded section of the guide post, which is beneficial to the stability of tool clamping.

[0028] Working principle: After the magnetic drilling machine finishes drilling a hole in the steel component, the drill bit is removed, and the fixture is installed on the magnetic drilling machine. An adjustment rod of appropriate length is selected based on the thickness of the steel component, and a matching guide post is selected based on the hole size. After the fixture is assembled, the magnetic drilling machine is moved so that the guide post of the fixture moves down and extends into the hole. After the magnetic drilling machine is positioned, it is magnetically fixed. The magnetic drilling machine pushes the fixture down, causing the cutting tool to press against the upper surface of the hole. At this time, the guide post extends into the hole, and the magnetic drilling machine drives the fixture to rotate. The cutting tool then smooths the upper surface of the hole. The cutting tool moves up, and after the cutting tool is removed, the fixture moves down in the hole so that the locking hole 131 on the fixture moves to below the hole. The cutting tool is installed, and the magnetic drilling machine drives the fixture up, causing the cutting tool to press against the lower surface of the hole. The magnetic drilling machine drives the fixture to rotate, and the cutting tool smooths the lower surface of the hole.

[0029] The countersinking tool, through the cooperation of the tapered shank sleeve, adjusting rod, connecting rod, cutting tool and guide post, can be used with magnetic drilling equipment to complete the reverse face flattening of steel components after drilling. The operation does not require the steel components to be moved, which reduces the equipment use cost and construction risk, and shortens the processing cycle.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
