[0017] Next, the technical solution of the present utility model will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0018] The present utility model discloses a screw gland improvement fixture, as Figure 1 shown, which includes a base 1, a positioning fixture 2, a gland pressing mechanism 3 and a detection and feedback mechanism. The positioning fixture 2 is fixed to the rear of the base 1. The gland pressing mechanism 3 includes a gland head and a driving motor 38. The driving motor 38 is fixed to the front end of the base 1, and the driving motor 38 drives the gland head to move up and down. The gland head includes a fixed gland 32 and a movable gland 31, and the movable gland 31 and the fixed gland 32 are movably connected in the front-rear direction.

[0019] The detection and feedback mechanism includes a pen rod cylinder 4 and a double rod cylinder 5. The pen rod cylinder 4 is fixed to the rear of the base 1, and the double rod cylinder 5 is fixed to the middle of the base 1. The movable gland 31 cooperates with the upper ends of the pen rod cylinder 4 and the double rod cylinder 5.

[0020] The detection and feedback mechanism is also equipped with a pressure sensor and a control system. The pressure sensors are respectively arranged in the pen rod cylinder 4 and the double rod cylinder 5. The pressure sensors are connected to an external controller. The pressure sensors real-time monitor the pressure parameters during the gland pressing process, and when an abnormality is found, the external controller issues an alarm in a timely manner.

[0021] As Figure 2 and Figure 3As shown in the figure, a rod cylinder 35 is fixedly provided at the upper end of one side of the fixed gland 32. The connecting rod 34 slides back and forth within the rod cylinder 35. The front end of the movable gland 31 protrudes outwardly with a baffle 33. The front end of the connecting rod 34 is fixedly connected to the baffle 33. Slide rails 36 are fixedly provided on the left and right sides of the fixed gland 32. N-shaped sliders 37 are provided on the left and right sides of the movable gland 31.
