Description

Technical Field

[0001] The utility model relates to the field of tapping tools, in particular to a tapping device. Background Art

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

[0003] During tapping, the tapping drill bit continuously rotates and feeds, which provides a certain amount of centrifugal force to the thread slag produced by tapping. If there is no shielding against the thread slag on the processing table, the thread slag will splash everywhere, which is quite dangerous. Summary of the invention

[0004] The technical problem to be solved by the utility model is that during tapping, since the tapping assembly continuously rotates and feeds, a certain centrifugal force will be provided to the wire scraps generated by tapping. If there is no shielding for the wire scraps on the processing table, the wire scraps will splash everywhere, which is quite dangerous.

[0005] In order to solve the above problems, the technical solution adopted by the utility model is: a tapping device, including a frame and a mounting sleeve arranged on a mounting rod above the frame, a processing table is arranged on one side of the mounting sleeve, a tapping assembly is installed on the mounting rod above the frame, and a protective frame plate and a closing plate are provided on the sliding outside of the processing table for shielding the splash of tapping slag.

[0006] The beneficial effect of the utility model is as follows: by arranging a protective frame plate and a closing plate to form a circle around the upper surface of the processing table to form a protective enclosure structure, the thread slag generated by the tapping assembly during tapping is shielded to prevent the thread slag from being thrown everywhere, thereby improving the safety of tapping to a certain extent.

[0007] The utility model further improves the technical solution adopted as follows: the protective frame plate is a U-shaped plate structure, T-shaped sliders are provided at both ends of the closing plate, a T-shaped slide groove cooperating with the T-shaped slider is opened on the inner side of the open end of the protective frame plate, a protrusion is provided on one side of the closing plate, and a groove is provided on the outer side of the protective frame plate to be plugged into the protrusion.

[0008] The beneficial effects of the above improvements are as follows: the cooperation of the T-shaped slider and the T-shaped slide groove facilitates fixing the protective frame plate and the closing plate together, and shielding the thread slag generated when the tapping assembly is in a working state; by utilizing the cooperation of the protrusion and the groove, when the tapping assembly is in a non-working state and there is no need to shield the processing table, the workpiece to be tapped can be fixedly clamped on the processing table, achieving the effect of inserting the closing plate on the outside of the protective frame plate, thereby avoiding the loss of the closing plate after the protective frame plate is separated.

[0009] As a further improvement of the utility model, the technical problem to be solved is: how to fix the protective enclosure structure composed of the protective frame plate and the closing plate on the processing table to ensure that the tapping assembly is not affected when it is in the processing state and the non-processing state.

[0010] In order to solve the above technical problems, the utility model further improves the technical solution adopted as follows: limit blocks are provided at the upper and lower parts of both ends of the opening of the protective frame plate, two limit plates are provided outside the mounting sleeve for rotation through the torsion spring shaft, and a notch is provided in the middle of the limit block for clamping with the limit plate.

[0011] The beneficial effect of the above improvement is: by utilizing the clamping connection between the limiting plate and the notches on the limiting blocks at different heights, the protection frame plates at different positions or states can be fixed.

[0012] As a further improvement of the present invention, the technical problem to be solved is: how to make the limiting plate accurately fit into the notch of the corresponding limiting block to complete the positioning of the protective frame plate in different states.

[0013] In order to solve the above technical problems, the utility model further improves the technical solution adopted as follows: a C-shaped groove is opened on the peripheral side of the bottom surface of the processing table plate, and a lower positioning strip plate cooperating with the C-shaped groove is provided at the bottom of the protective frame plate; a stop plate is protruding from the bottom of the side of the processing table plate toward the mounting sleeve, and the two upper limit blocks are provided with an upper positioning plate abutting against the stop plate on the opposite side.

[0014] The beneficial effects of the above improvements are as follows: by utilizing the cooperation between the U-shaped groove and the lower positioning strip, a limiting effect is achieved when the protective frame plate slides upward, making it easier for the limiting plate to be inserted into the corresponding limiting block gap; by utilizing the abutment between the upper positioning plate and the stop plate, a limiting effect is achieved when the protective frame plate slides downward, making it easier for the limiting plate to be inserted into the corresponding limiting block gap.
