[0031] Embodiment 1

[0032] Refer to Figures 1-5, which is the first embodiment of the present utility model, provides a production and processing device for sucker rods. Such a production and processing device for sucker rods includes a base 1. On one side of the top of the base 1, a side box 2 is welded. Inside the side box 2, a driving motor is fixedly installed, and the driving end of the driving motor is located outside the side box 2. The driving end of the driving motor is fixedly connected to a rotating disk 3. And on the side of the rotating disk 3 away from the side box 2, a guide rod 36 is fixedly arranged. At the end of the guide rod 36 away from the rotating disk 3, a cutter head 37 is fixedly arranged;

[0033] On both sides of the top of the base 1, fixed rod driving and clamping frames 4 are fixedly installed. On the side of the base 1 away from the side box 2, a translation seat 6 is arranged. And at the bottom of the translation seat 6, universal wheels are fixedly installed. On the top of the translation seat 6, a movable rod driving and clamping frame 5 is fixedly installed. And the translation seat 6 is flush with the top of the base 1. At the same time, the structures and sizes of the fixed rod driving and clamping frame 4 and the movable rod driving and clamping frame 5 are the same;

[0034] The fixed rod driving and clamping frame 4 includes two electric telescopic rods three 41. The movable ends of the two electric telescopic rods three 41 are fixedly connected to a bearing plate 42. At the front and rear ends of one side of the bearing plate 42, vertical bars 43 are welded. Between the two vertical bars 43, a supporting shaft 44 is rotatably installed through a bearing. On the top of the bearing plate 42 and on the side away from the supporting shaft 44, a driving source 45 is fixedly installed. And the driving end of the driving source 45 is rotatably provided with a driving shaft 46. And the sucker rod is located on the upper surface of the supporting shaft 44 and between the two driving shafts 46. The bottom edge of the sucker rod is supported by the supporting shaft 44. Then, the two linear motors 451 drive the movable plates 452 to move simultaneously, moving the two driving shafts 46 towards the middle to clamp the sucker rod between the two driving shafts 46.

[0035] Inside the base 1, an electric telescopic rod five 7 is fixedly installed. And the movable end of the electric telescopic rod five 7 passes through the side of the base 1 and is connected to the side of the translation seat 6 close to the base 1. The telescoping of the electric telescopic rod five 7 can adjust the distance between the translation seat 6 and the base 1, and adjust the position of the translation seat 6 according to the length of the sucker rod. When threading a longer sucker rod, the sucker rod is supported at three points to ensure the stability of the support for the sucker rod. And when not in use, the translation seat 6 can be retracted towards the side of the base 1 to reduce the area occupied by the device.

[0036] The driving source 45 includes two linear motors 451 installed on the top of the bearing plate 42. The movable end of the linear motor 451 is fixedly connected with a movable plate 452.

[0039] During use, the sucker rod to be threaded is placed between two fixed rod driving clamping frames 4 and one movable rod driving clamping frame 5. The electric telescopic rod IV 472 extends to drive the lower pressing roller 474 to move downward and press the lower pressing roller 474 on the upper surface of the sucker rod.

[0040] The servo motor 453 drives the driving shaft 46 to rotate, and under the action of the frictional force between the driving shaft 46 and the sucker rod, the sucker rod is driven to move towards the rotating disk 3.

[0041] After the sucker rod is fixed, the driving motor drives the rotating disk 3 to rotate, then the driving tool head 37 is driven to rotate. While the tool head 37 is rotating, the driving shaft 46 drives the sucker rod to move towards the rotating disk 3, making the tool head 37 contact the outer wall surface of the sucker rod and perform threading operation. After threading is completed, the electric telescopic rod I 32 extends to make the tool head 37 disengage from the sucker rod, and then the sucker rod is removed.
