DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-7As shown, a clamping mechanism for a mechanical seal assembly machine comprises a press body 1; a first servo motor 11 is fixedly connected to one side of the press body 1; a first gear 12 is fixedly connected to the output end of the first servo motor 11; a press housing 13 is fixedly connected to the inner side of the press body 1; a bearing 16 is rotatably connected inside the press housing 13; a second gear 14 is fixedly connected to the top of the bearing 16; the first gear 12 is meshed in the middle of the second gear 14; a threaded barrel 15 is threadedly connected to the inside of the second gear 14; a sensing block 17 is fixedly connected to the bottom of the threaded barrel 15; a connecting spring 19 is fixedly connected to the outside of the sensing block 17; a threaded ring 100 is fixedly connected to the bottom of the connecting spring 19; a striking column 18 is fixedly connected to the top of the threaded ring 100; a replaceable pressing block 101 is threadedly connected to the inside of the threaded ring 100; a placement hole 102 is provided at the bottom of the press body 1; a The storage frame 103; when working, the first servo motor 11 drives the first gear 12 to start rotating, driving the second gear 14 and the bearing 16 to rotate inside the press housing 13. Since the threaded barrel 15 is threadedly connected to the bearing 16, the threaded barrel 15 can be raised or lowered. The protrusion on the top of the threaded barrel 15 can act as a limiter when it descends. The replaceable pressure block 101 is installed on the threaded ring 100 by rotation. The threaded barrel 15 descends, and the replaceable pressure block 101 touches the seal to press back, so that the connecting spring 19 is compressed, so the impact column 18 will squeeze the sensor block 17. When the seal is pressed, it is necessary to ensure that the seal is perpendicular to the shaft to be installed and parallel to the pressure block. If the seal is parallel to the pressure block, eight groups of sensor blocks 17 are squeezed at the same time, and the machine operates normally. If the number of squeezed sensor blocks 17 is less than eight, an alarm is issued, which greatly reduces the possibility of seal breakage or shaft scrapping due to seal tilt.

[0027] like Figure 1-5 , Figure 7As shown, a protruding plate 29 is fixedly connected to the side of the press body 1; a second slide groove 27 is provided on one side of the top of the press body 1; a first slide groove 21 is provided on the top of the protruding plate 29; a product-shaped slider 22 is slidably connected inside the first slide groove 21; a second servo motor 2 is fixedly connected to the top of the product-shaped slider 22; a replacement component 5 is connected to the output end of the second servo motor 2; a connecting rod 23 is fixedly connected to the end of the replacement component 5 away from the second servo motor 2; a bidirectional lead screw 26 is fixedly connected to the end of the connecting rod 23; a fixed card 25 is threadedly connected to the middle of the bidirectional lead screw 26; a slide rod 24 is slidably connected to the end of the fixed card 25 away from the bidirectional lead screw 26; the slide rod 24 is slidably connected inside the second slide groove 27; the connecting rod 23 is slidably connected inside the second slide groove 27; a limiting block 28 is fixedly connected to the middle of the slide rod 24 The end of the bidirectional lead screw 26 is rotatably connected to the storage frame 103; the end of the slide bar 24 is rotatably connected to the storage frame 103; during operation, the second servo motor 2 drives the connecting rod 23 to rotate, so that the two sets of fixed card plates 25 are close to each other, thereby playing a certain fixing role on the shaft body. Because the slide bar 24 and the connecting rod 23 are slidably connected inside the second slide groove 27, the product-shaped slider 22 can also slide inside the first slide groove 21, so that the storage frame 103 can slide on the top of the press body 1. When installing the seal on the shaft body, the shaft body may not be stable enough due to the uneven end of the shaft body. Therefore, the stability is increased by clamping the two sets of fixed card plates 25. Because the shaft body may be heavy, it needs to be lifted with tools such as a trolley. The storage frame 103 can be slid by sliding, and there is no obstruction above the storage frame 103, which is convenient for loading and unloading the shaft body, greatly improving work efficiency.

[0028] like Figure 1-5 As shown, the bottom of the press body 1 is provided with a third servo motor 3; the inner side of the placement hole 102 is rotatably connected with a rotating ring 36; the output end of the third servo motor 3 is fixedly connected with an electric telescopic platform 31; the top of the electric telescopic platform 31 is fixedly connected with a chuck 35; the top of the chuck 35 is provided with a third slide groove 37; the inner side of the third slide groove 37 is fixedly connected with a limiting column 32; the middle part of the limiting column 32 is provided with a shock absorbing spring 33; the middle part of the limiting column 32 is slidably connected with a clamping block 34; when working, the shaft body is placed in the placement hole 10 2, and then the electric telescopic table 31 is extended and retracted, the shaft body will squeeze the clamping block 34 to displace it, squeeze the shock-absorbing spring 33, and the shock-absorbing spring 33 provides a reaction force to clamp the bottom of the shaft body. At the same time, the third servo motor 3 can drive the shaft body to rotate. When the seal is pressed, some seals may be displaced when subjected to the rotational force because of the rotational pressing. At this time, the third servo motor 3 can be used to realize the synchronous rotation of the shaft body, thereby reducing the loss caused by the interference of the rotational force when the seal is pressed.

[0029] like Figure 1 , Figure 3-5As shown, a fixed block 4 is fixedly connected to the inner side of the press body 1; a rotating shaft 41 is rotatably connected to the inner side of the fixed block 4; a telescopic rod 42 is fixedly connected to the top of the rotating shaft 41; a sealant spray head 43 is fixedly connected to the end of the telescopic rod 42; a cleaning brush 44 is fixedly connected to the end of the telescopic rod 42 on the other side; when working, the cleaning brush 44 is first moved close to the shaft body to clean the part where the seal needs to be installed, and then the sealant spray head 43 is moved to spray the sealant on the cleaned part. The stains on the shaft body will affect the sealing effect and service life of the seal, so it is cleaned before installation and then sprayed with sealant to enhance the sealing effect and increase the service life of the seal.

[0030] like Figure 4 , Figure 7 As shown, the replacement component 5 includes four corner blocks 54; the four corner blocks 54 are fixedly connected to the ends of the connecting rod 23; the four corner caps 53 are slidably connected to the outside of the four corner blocks 54; the ends of the four corner caps 53 are fixedly connected to the telescopic columns 51; a supporting spring 52 is provided on the outside of the telescopic columns 51; the side of the telescopic columns 51 away from the four corner caps 53 is fixedly connected to the second servo motor 2; during operation, the four corner caps 53 are pulled to make the four corner caps 53 and the four corner blocks 54 fall off, and the telescopic columns 51 will be extended and retracted as the four corner caps 53 are pulled. This step can separate the second servo motor 2 from the connecting rod 23, thereby improving the efficiency of cleaning and maintenance thereof in the later stage.

[0031] like Figure 4 , Figure 7 As shown, a buffer spring 6 is fixedly connected to the inner side of the first slide groove 21; a buffer block 61 is fixedly connected to the end of the buffer spring 6; during operation, the buffer block 61 squeezes the buffer spring 6. This step provides a buffering effect when the product-shaped slider 22 slides in the first slide groove 21, making the operation more stable and reducing the possibility of damage caused by collision during movement.

[0032] like Figure 1-5 As shown, a sliding pad 7 is fixedly connected to the end of the fixed clamp plate 25; during operation, as the fixed clamp plate 25 squeezes the shaft body, the sliding pad 7 will squeeze the shaft body. This step is because during operation, the shaft body may rotate and may rub the fixed clamp plate 25, thereby accelerating the wear of the fixed clamp plate 25 and causing damage to the shaft body shell. At this time, the sliding pad 7 can act as a buffer to reduce the possibility of damage to the shaft body due to rotation.

[0033] Working principle: the first servo motor 11 drives the first gear 12 to start rotating, driving the second gear 14 and the bearing 16 to rotate inside the press housing 13. Since the threaded barrel 15 is threadedly connected with the bearing 16, the threaded barrel 15 can be raised or lowered. The protrusion on the top of the threaded barrel 15 can be used as a limiter when it descends. The replaceable pressure block 101 is installed on the threaded ring 100 by rotation. The threaded barrel 15 descends, and the replaceable pressure block 101 touches the seal to press back, so that the connecting spring 19 is compressed, so the impact column 18 will squeeze the sensor block 17. When the seal is pressed, it is necessary to ensure that the seal is perpendicular to the shaft to be installed and parallel to the pressure block. If the seal is parallel to the pressure block, the eight groups of sensor blocks 17 will be squeezed at the same time, and the machine will operate normally. If there are less than eight induction blocks 17 squeezed, an alarm is sounded, which greatly reduces the possibility of seal breakage or shaft failure due to seal tilt. The second servo motor 2 drives the connecting rod 23 to rotate, so that the two sets of fixed card plates 25 are close to each other, thereby fixing the shaft to a certain extent. Because the slide bar 24 and the connecting rod 23 are slidably connected inside the second slide groove 27, the product-shaped slider 22 can also slide inside the first slide groove 21, so that the storage frame 103 can slide on the top of the press body 1. When installing the seal on the shaft, the shaft end may be unstable due to the unevenness. Therefore, the two sets of fixed card plates 25 are clamped to increase its stability. Because the shaft may be heavy, it needs to be lifted by a trolley or other tools, which can be lifted by sliding the storage frame 103, there is no obstruction above the storage frame 103, which is convenient for loading and unloading the shaft body and greatly improves work efficiency. The shaft body is placed above the placement hole 102, and then the electric telescopic table 31 is extended and retracted. The shaft body will squeeze the clamping block 34 to displace it and squeeze the shock-absorbing spring 33. The shock-absorbing spring 33 provides a reaction force to clamp the bottom of the shaft body. At the same time, the third servo motor 3 can be used to drive the shaft body to rotate. When the seal is pressed, some seals may be displaced when subjected to the rotational force due to rotational pressure. At this time, the third servo motor 3 can be used to realize synchronous rotation of the shaft body, reducing the loss caused by the interference of the rotational force when the seal is squeezed. First, the cleaning brush 44 is moved close to the shaft body, and the part where the seal needs to be installed is cleaned. Clean it, then move the sealant nozzle 43 to spray the sealant on the cleaned part. The stains on the shaft body will affect the sealing effect and service life of the seal, so it is cleaned before installation, and then sprayed with sealant to enhance the sealing effect and increase the service life of the seal. Pull the four-corner cap 53 to make the four-corner cap 53 and the four-corner block 54 fall off. The telescopic column 51 will be extended and retracted as the four-corner cap 53 is pulled, so that the second servo motor 2 can be separated from the connecting rod 23, which improves the efficiency of cleaning and maintenance in the later stage. The buffer block 61 squeezes the buffer spring 6 to provide a buffering effect when the product-shaped slider 22 slides in the first slide groove 21, making the work more stable and reducing the possibility of damage caused by collision during movement.As the fixed card plate 25 presses the shaft, the sliding pad 7 will press the shaft. During operation, the shaft may rotate and rub against the fixed card plate 25, thereby accelerating the wear of the fixed card plate 25 and causing damage to the shaft shell. At this time, the sliding pad 7 can act as a buffer to reduce the possibility of damage to the shaft due to rotation.

Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model.
