Description

Technical Field

[0001] The utility model relates to the technical field of building material processing equipment, in particular to a drill collar external thread processing device. Background Art

[0002] Drill collars are mainly used to drill holes in various materials, including metal, wood, plastic, etc. They can form holes on the surface of the material, which facilitates subsequent processing and assembly. Drill collars are also often used to process threads in the drilled holes. These threads can be used to install bolts, nuts or other threaded connectors to fix two or more parts and provide high connection strength. Drill collars can provide stronger connections than ordinary straight holes. Threaded connections fix two threaded parts by twisting them, creating a tighter bond, thereby improving the strength and stability of the connection. Threaded connectors can be easily unscrewed, so it is more convenient when repairs or replacement of parts are needed. This connection method is easier to disassemble than welding or gluing connections, and threaded connections are easier and faster to assemble than other methods.

[0003] After searching, an external thread processing device is disclosed in the announcement number: CN208825763U, which includes at least two groups of workpiece clamping mechanisms and corresponding workpiece threading mechanisms; one end of the workpiece is mounted on the clamping mechanism and is connected to the clamping mechanism by a moving pair, and the other end is coaxially mounted with the die of the threading mechanism, and the clamping mechanism is provided with an adjustment element for driving the workpiece to move, and a transmission mechanism for selecting a threading mechanism to transmit torque is installed under each threading mechanism, and the input end of the transmission mechanism is connected to a power source. Although this application shortens the time for material preparation and clamping and improves production efficiency, it does not take into account the different heights and sizes of each workpiece during the processing of the external thread, and the height of the processing device cannot be adjusted, which makes it difficult to adapt to different work requirements, which may lead to a decrease in work efficiency and thus affect the flexibility of the processing device.

[0024] Specifically, first, the output end of the hydraulic cylinder 4 and the front end support pillar 5 are subjected to force to drive the fixed column 12 on the inner wall of the sliding ring 13 on both sides of the support plate 24 so that the support plate 24 can move up and down, so that the support plate 24 can be close to the material to be processed, and the motor 3 can be turned on, because the output end of the motor 3 is connected to the pulley 2 8 and the pulley 2 8 is subjected to force to connect the outer wall to the synchronous belt 7. At this time, the inner wall of the synchronous belt 7 is connected to the pulley 1 6, and the pulley 1 6 is subjected to force to drive the hollow column 9 connected below to rotate, thereby cutting the tapping 23 on the inner wall of the hollow column 9. In this way, the use of the hollow column 9 can ensure safety to the greatest extent and increase rigidity to the maximum strength.
