The coupling pre-screwing machine is the device that fast box cupling is screwed into tubing and casing, carries out screw-on machine after this process is finished again and tightens, and demarcates moment.The full-automatic pre-machine cost of twisting is high, and a lot of manufacturers would rather adopt artificial twisting to connect, and does not also go to buy expensive equipment, so most of manufacturer uses the mode of manually tightening.But artificial pre-twisting also has drawback, and a little bit smaller box cupling can just can be finished in people's operation, and people of box cupling large for caliber, wall thickness is difficult to finish, and needs more people's deallocation to close and finishes, and has caused personnel's waste, and match ratio that the people is many simultaneously is difficult.
The utility model content
Technical problem to be solved in the utility model is that a kind of simple and reliable semi-automatic coupling pre-screwing device that is used for oil casing collar is provided for shortcoming of the prior art, it can overcome manually-operated defective, satisfy the requirement in the production process, shorten the working time simultaneously, improved output.
Adopt following technical scheme for solving technical problem of the present utility model:
A kind of semi-automatic coupling pre-screwing device, comprise base, one lift is set on the described base, the other end of described lift connects hoisting rack, described hoisting rack connects floating shelf by spring, described floating shelf connects the arm of force, and the described arm of force is connected with the two ends of cylinder, and the upper end of the described arm of force arranges clamping plate.
Described floating shelf is comprised of arm of force connecting plate, supporting plate, handrail, base plate and spring joint pin, two handrails vertically are set on the described base plate, described supporting plate is inclined on the base plate by handrail, described two blocks of supporting plates form " V " type, described arm of force connecting plate is arranged on the base plate both sides, the below of described base plate arranges the spring joint pin, and described spring joint pin is sleeved in the spring.
The described arm of force is arranged on the floating shelf with the bearing pin connection.
Described base below arranges roller, and described roller is arranged on the guide rail, and described guide rail setting on the ground.
The utility model adopts cylinder action in the clamping plate on the arm of force box cupling to be fixed on the floating shelf, and floating shelf connects the structure that is connected hoisting rack with lift by spring simultaneously.The lift of this structure can promote the box cupling that hoisting rack moves up and down to adapt to different tube diameters, and simultaneously spring connection can make floating shelf seesaw up and down, twists smoothly with the center that makes things convenient for centering box cupling and tubing and casing to connect.Simultaneously at base roller is housed, whole equipment can be moved at guide rail, be used for estimating the aligning steel pipe.The utility model is a kind of simple and reliable semi-automatic coupling pre-screwing device that is used for oil casing collar, simple in structure, cost of manufacture is low, and is practical, goes slick, simple to operate, it has overcome manually-operated defective, has satisfied the requirement in the production process, has shortened the working time simultaneously, save the production cycle, improved output and production efficiency.
