Description

Technical Field

[0001] The utility model relates to the technical field of tapping machines, in particular to a tapping machine for steel structure processing. Background Art

[0002] The tapping machine is a mechanical processing equipment that processes internal threads, screws or teeth buttons on the inner side of holes of various parts with different specifications of through holes or blind holes, such as machine housings, equipment end faces, nuts, flanges, etc.

[0003] When traditional tapping machine taps are used to process threads on the surface of steel structures, the taps are prone to mutual wear when drilling and grinding with the inside of the slot, which affects the service life of the taps. Traditional taps need to be continuously filled with lubricant from the outside of the slot during drilling and grinding, which is cumbersome and requires the taps to be started and stopped, affecting processing efficiency. Therefore, we propose a tapping machine for steel structure processing. Utility Model Content

[0004] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a tapping machine for steel structure processing.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a tapping machine for steel structure processing, comprising a machine head, a mounting end, a socket handle and a tap, an oil chamber for storing lubricating oil being provided inside the tap, an oil hole penetrating the oil chamber being provided on the periphery of the tap, absorbent cotton being provided on the inner side of the oil hole, a micro cover being installed on one side of the absorbent cotton through a circular shaft, a filling hole penetrating the oil chamber being provided on the top of the tap, and a sealing plug being provided inside the filling hole to seal the inner side of the filling hole.

[0006] Preferably, the absorbent cotton itself has absorption properties and tension. When the tap starts to rotate, the micro cover can push the oil in the oil chamber to the absorbent cotton through centrifugal force. When the absorbent cotton is swung and squeezed on the circular shaft, the absorbent cotton itself is in an open oil-swinging state.

[0007] Preferably, the external sliding sleeve of the sleeve handle is provided with a sleeve connecting part, a rectangular sleeve is installed on one side of the sleeve connecting part, a telescopic sliding magnetic block is provided inside the rectangular sleeve, the magnetic block itself has magnetic properties, and a limiting part that cooperates with the rectangular sleeve is installed on the top of the magnetic block.

[0008] Preferably, a spherical hole is provided at the bottom of the magnetic block, the spherical hole is a three-quarter spherical hollow slot, and a movable ball is provided inside the spherical hole.

[0009] Preferably, a connector is installed on one side of the magnetic block, and a support spring is installed on the top of the connector to connect and cooperate with the bottom support of the rectangular sleeve.

[0010] Preferably, a limiting sleeve is installed on the outer sleeve of the sleeve handle, and a screw sleeve that can limit and fix the sleeve part is installed on the outer periphery of the sleeve handle through a thread.

[0011] Beneficial effects

[0012] The utility model provides a tapping machine for steel structure processing, which has the following beneficial effects:

[0013] (1) A tapping machine for processing steel structures, in this article, an oil chamber for storing lubricating oil is opened inside the tap. After the oil is filled into the oil chamber through the filling hole, when the tap is installed and started with the sleeve handle, the lubricating oil in the oil chamber is pushed into the oil hole by the centrifugal force of the high-speed rotation of the tap, and the micro cover inside the oil chamber is swung again, and the oil is pushed into the oil hole. The absorbent cotton will open when squeezed by the circular shaft, so that the oil can be automatically thrown out into the external steel structure slot hole through the absorbent cotton under the swing, reducing the mutual wear between the tap and the outer steel structure slot hole, and no manual start of the oil addition operation is required, thereby achieving the effect of improving the tap processing efficiency.

[0014] (2) A tapping machine for processing steel structures, wherein the outer sleeve of the sleeve handle is provided with a sleeve piece that is connected to the limit sleeve, and the sleeve piece is fixed by a screw sleeve and a threaded sleeve on the outer side of the sleeve handle, and a telescopic magnetic block is provided on one side of the sleeve piece through a rectangular sleeve. When the tap passes through the machine head for drilling and grinding, the waste chips produced by the tap drilling and grinding will contact the magnetic block when it is swung, and the magnetic block itself has magnetism, so the magnetic block can magnetically absorb and collect the swung waste chips. When the tap moves into the slot hole of the steel structure, the magnetic block can adapt to the elastic support and telescopic movement through the support spring, and the movable ball at the bottom of the magnetic block can contact the steel structure to avoid friction of the magnetic block itself. In this way, the magnetic block can automatically collect the waste chips produced by the tap, thereby achieving the effect of automatically collecting the waste chips produced by the tap drilling and grinding, avoiding accumulation and blockage in the slot hole of the steel structure, and affecting the drilling and grinding quality of the tap.
