Description

Technical Field

[0001] The present invention relates to the technical field of turning processing, in particular to a turning device used for valve production. Background Art

[0002] Turning is lathe processing, which is a part of mechanical processing. Lathe processing mainly uses a turning tool to turn the rotating workpiece. Turning is a cutting process in which the workpiece rotates and the turning tool moves in a straight line or curve in the plane. Turning is generally performed on a lathe to process the inner and outer cylindrical surfaces, end faces, conical surfaces, forming surfaces and threads of the workpiece. When turning the inner and outer cylindrical surfaces, the turning tool moves in a direction parallel to the axis of rotation of the workpiece. When turning the end face or cutting the workpiece, the turning tool moves horizontally in a direction perpendicular to the axis of rotation of the workpiece.

[0003] In the prior art, valves often need to be turned during production and processing to ensure their dimensional accuracy and surface finish. Since both ends of the valve need to be docked with equipment components when in use, both ends need to be turned during processing. When processing the valve, the existing turning device usually clamps and fixes one end of the valve and then turns the other end of the valve. At this time, the staff needs to swap the processed end of the valve and clamp the other end, and then the valve needs to be clamped for a second time. Then, when the valve is clamped for the second time, since the operation is usually performed manually, the concentricity of the valve during clamping needs to be judged by the naked eye, which will cause the concentricity of the two ends of the valve to deviate during processing and affect the processing effect.

[0053] After the above step is completed, the worker puts the loading cover 8 with the valve into the inside of the CNC lathe body 1 and abuts against the closing plate 10, and places the middle part of the valve between the two closing plates 10 through the plurality of limiting plates 47, and then the worker closes the two closing plates 10, in the process, the rotation of the closing plate 10 will drive the second guide frame 33 and the positioning seat 37 to slide, and then the two installation shells 32 will simultaneously approach each other to close, and the valve is self-centering clamped and fixed through the rebounding force of the plurality of third springs 25, and then the plurality of rollers 39 inside the installation shell 32 and the plurality of brass retaining rings 40 on the surface thereof will adhere to the surface of the valve, and the brass material of the brass retaining ring 40 can prevent the valve from being damaged, and the approaching of the two closing plates 10 will drive the two positioning columns 41 to pull the second connecting frame 35, so as to self-centering clamp and fix the valve to be processed, and the worker can rotate the connecting disc 6 to fix the plurality of valves to be processed in the inside of the plurality of closing plates 10;

[0054] After the above step is completed, the worker starts the driving assembly and the electric three-jaw chuck of the CNC lathe body 1 through the control panel of the CNC lathe body 1, and then the driving shaft of the second motor 14 drives the first adjusting screw 15 to rotate, and then the closing plate 10 moves up and down to the position corresponding to the center of the electric three-jaw chuck of the CNC lathe body 1 under the threaded transmission of the slide rod 20 and the first adjusting screw 15, at this time the extension rod of the first pneumatic push rod 5 retracts to drive the sliding seat 4 to move, and then the connecting disc 6 and the first connecting frame 7 move, and the valve enters the inside of the electric three-jaw chuck, and then the valve is clamped and fixed through the electric three-jaw chuck, so as to complete the effect of automatically feeding and clamping the valve to be processed in the inside of the CNC lathe body 1;

[0055] When one end of the valve is processed, the staff moves the valve out of the three-jaw chuck through the control panel of the CNC lathe body 1, and then the staff uses the control panel of the CNC lathe body 1 to start the second pneumatic push rod 29 corresponding to the current work station. Then the telescopic rod of the second pneumatic push rod 29 extends to drive the adjusting head 30 to move. At this time, the adjusting head 30 pushes the adjusting block 31 to move the adjusting rod 22, and then the first connecting rod 27 rotates. The movement of the adjusting rod 22 drives the two second connecting rods 36 to drive the turning frame 9 to rotate, so that the valve can be flipped and swapped, and both ends of the valve can be processed. At the same time, after the processing of a single valve is completed, the staff can move the valve out of the three-jaw chuck through the drive assembly, and drive the connecting disk 6 and the multiple turning frames 9 outside it to rotate through the drive shaft of the first motor 11, so that multiple valves placed inside the CNC lathe body 1 can be processed in turn, thereby facilitating batch turning of valves and automatically flipping and swapping the valves during processing, ensuring the concentricity of the two ends of the valve during turning.

[0056] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
