Description

Technical Field

[0001] The invention relates to the technical field of bearing oil seal assembly equipment, in particular to a bearing oil seal hydraulic assembly device for a reducer. Background Art

[0002] The main function of the bearing oil seal is to seal the bearing to prevent the leakage of lubricating oil. At the same time, it also prevents dust, moisture and other impurities from entering the bearing, keeps the bearing clean and lubricated, and thus extends the service life of the bearing. The sealing principle of the oil seal is the oil film controlled by the oil seal edge. This oil film has fluid lubrication characteristics. Under the action of the surface tension of the liquid, the stiffness of the oil film just makes the oil film and the air contact end form a crescent surface, preventing the leakage of the working medium, thereby achieving the sealing of the rotating shaft.

[0003] Among them, in order to ensure the sealing performance of the oil seal, most oil seals need to be repeatedly knocked vertically on the outer wall of the oil seal during installation to ensure that the oil seal ring shell is completely fitted to the inner wall of the bearing. In this process, due to the hard contact between the oil seal ring and the hammer, this will cause the outer wall of the oil seal ring to deform slightly, which will seriously affect the sealing effect of the oil seal ring when the equipment is running at high speed. In response to the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a hydraulic assembly device for a bearing oil seal of a reducer, comprising a base, a mounting bracket fixedly connected to the top of the base, a spring telescopic rod fixedly connected to one end of the mounting bracket away from the base, a mounting plate fixedly connected to one end of the spring telescopic rod away from the mounting bracket, a motor fixedly connected to the inner wall of the mounting plate, a support frame fixedly connected to the top of the motor, a threaded tube rotatably connected to the inner wall of the support frame, and an arc groove is provided on the inner wall of the threaded tube;

[0005] The driving mechanism comprises a driving tube fixedly connected to the output shaft of the motor, a fixing rod fixedly connected to the inner wall of the driving tube, a spring telescopic rod 2 fixedly connected to the side wall of the fixing rod, an inclined slider fixedly connected to the end of the spring telescopic rod 2 away from the fixing rod, an outer wall of the inclined slider is slidably connected to the through hole of the driving tube, a fixing column fixedly connected to the top of the driving tube, a fixing plate fixedly connected to the top of the fixing column, an electric telescopic rod rotatably connected to the top of the fixing plate, an end of the electric telescopic rod away from the fixing plate is fixedly connected to the bottom of the mounting bracket, and two inclined grooves are provided on the side wall of the fixing plate;

[0006] The knocking mechanism comprises a telescopic rod 1 fixedly connected to the outer wall of the mounting plate, the end of the telescopic rod 1 away from the mounting plate is fixedly connected to a square slide cylinder, the inner wall of the square slide cylinder is slidably connected to a knocking rod, the top of the knocking rod is fixedly connected to a bearing rod, the bottom of the bearing rod is fixedly connected to a spring 1, the top of the mounting plate is fixedly connected to a fixed bracket, the end of the fixed bracket away from the mounting plate is rotatably connected to a prying rod, the side wall of the prying rod is fixedly connected to a knocking block, the end of the prying rod away from the knocking block is rotatably connected to a ball, a spring 2 is fixedly connected to the side wall of the fixed bracket, and an adjustment component is threadedly connected to the outer wall of the threaded tube. In order to solve the problem of slight deformation of the sealing ring due to hard contact, a driving mechanism and a knocking mechanism are arranged inside the equipment. Before use, the bearing is placed on the top of the base, and then the staff places the sealing ring inside the bearing, and then turns on the power of the electric telescopic rod and the motor. The electric telescopic rod forces the mounting plate and the knocking rod to move downward, and forces the knocking rod to enter the inner wall of the sealing ring, presenting a Figure 1 At this time, the motor drives the top fixed column and the fixed plate to rotate through the driving tube, and the rotating fixed plate will drive the inclined groove to rotate synchronously. During the rotation of the fixed plate, the bottom of the fixed plate will contact the outer wall of the ball, and force the ball to drive the prying rod to rotate downward. When the end of the prying rod close to the ball rotates downward, the end of the prying rod close to the knocking block will tilt upward, presenting a Figure 8 The state of middle H, and spring 2 is pulled at this time and accumulates mechanical power. When the inclined groove reaches the top of the ball, the ball loses the restriction of the bottom of the fixed plate. At this time, spring 2 will release mechanical power, forcing the prying rod to drive the knocking block to swing downward, and hit the top of the bearing rod through the knocking block. The bearing rod transmits the compressed force to the top of the sealing ring through the knocking rod, so that the sealing ring is pressed into the bearing. Through the application of the above components, the force of the hard collision between the sealing ring and the hammer is reduced, and the deformation of the sealing ring under pressure is reduced.

[0007] Preferably, one end of the spring 2 away from the fixed bracket is fixedly connected to the side wall of the prying rod, and one end of the spring 1 away from the bearing rod is fixedly connected to the top of the square slide. By utilizing the characteristics of the knocking block knocking the bearing rod, two inclined grooves are arranged inside the device, and the two inclined grooves are in a diagonal state on the fixed plate. When the inclined grooves rotate, when the two inclined grooves reach the top of the corresponding ball, the corresponding knocking block will knock downwards, presenting a Figure 8 The two diagonal knocking blocks apply downward pressure, which will force the diagonal knocking rods to apply equal pressure to the top of the sealing ring. Through the application of the above components, the knocking area is dispersed to ensure that the knocking force on each position of the sealing ring is equal, avoiding unidirectional knocking of the knocking blocks, which may cause the sealing ring to tilt.

[0008] Preferably, the adjustment component includes a threaded block threadedly connected to the outer wall of the threaded tube, a plurality of grooves are provided on the outer wall of the threaded block, and a hydraulic telescopic rod is fixedly connected to the inner walls of the plurality of grooves.

[0009] Preferably, the adjustment component also includes an outer support rod fixedly connected to the other end of the hydraulic telescopic rod one, and the end of the outer support rod away from the hydraulic telescopic rod one is rotatably connected to the outer wall of the square slide cylinder. Taking advantage of the fact that the sealing ring is mostly formed in a circular ring shape, an adjustment component is arranged inside the equipment. When the motor drives the driving tube and the fixed rod to rotate, during the rotation of the fixed rod, the spring telescopic rod two will force the inclined slider to fit tightly inside the arc groove, presenting a shape like Figure 7 In the state shown, the driving tube rotates counterclockwise at this time, and the threaded tube will be driven to rotate through the inclined slider. The rotation of the threaded tube will force the threaded block to have a downward trend. The downward-moving threaded block drives one end of the outer support rod to move downward through the hydraulic telescopic rod, while the other end of the outer support rod cannot move downward due to the influence of the square slide. Therefore, the outer support rod will force the square slide and the knocking rod to expand outward, so that the outer walls of the multiple knocking rods are tightly attached to the inner wall of the sealing ring. Through the application of the above-mentioned components, the multiple knocking rods can be adjusted according to the size of the sealing ring, so that the equipment can adapt to sealing rings of different specifications and sizes, thereby improving the scope of application of the equipment.

[0010] Preferably, the adjustment component also includes a transmission tube fixedly connected to the outer wall of the hydraulic telescopic rod one, a sliding plate is slidably connected to the outer wall of the knocking rod, and the bottom of the sliding plate is through-connected to two liquid storage tanks. Utilizing the characteristic of the above-mentioned outer support rod driving the outer support of the knocking rod, an adjustment component is arranged inside the equipment. When the knocking rod cannot continue to move outward, the outer support rod is blocked and will compress the hydraulic telescopic rod one, so that the internal liquid of the hydraulic telescopic rod one is transmitted to the inside of the liquid storage tank through the transmission tube. The liquid inside the liquid storage tank forces the hydraulic telescopic rod two to extend, driving the outer wall of the contact slide rail to contact the outer wall of the sealing ring, and the two contact slide rails will clamp and limit the inner wall of the sealing ring when they are stretched outward. Through the application of the above-mentioned components, it is avoided that when the knocking block knocks the knocking rod, there is a large separation distance between the bottom of the knocking rod and the outer wall of the sealing ring, resulting in a large distance between the bottom of the knocking rod and the outer wall of the sealing ring during subsequent knocking, resulting in slight deformation of the outer wall of the sealing ring.

[0011] Preferably, the adjustment assembly further comprises a second hydraulic telescopic rod connected through the side wall of the liquid storage tank, and one end of the second hydraulic telescopic rod away from the liquid storage tank is slidably connected to a contact rail.

[0012] Preferably, the adjustment component also includes a spring three fixedly connected to the side wall of the contact slide rail, the other end of the spring three is fixedly connected to the outer wall of the hydraulic telescopic rod two, and as the knocking rod is tightly against the inner wall of the sealing ring, the knocking rod and the square slide cylinder cannot move outward, which will limit the continued downward movement of the threaded block, and when the threaded block can no longer move downward, the resistance to the rotation of the threaded tube will gradually increase, and as the resistance of the threaded tube increases, the inclined slider will slide along the inner wall, so that the driving tube rotates along the threaded tube. Through the application of the above-mentioned components, the threaded block will no longer descend after the knocking rod is tightly against the outer wall of the sealing ring, thereby preventing the outer support rod from expanding outward during the subsequent knocking process of the equipment, causing the knocking rod to excessively squeeze the sealing ring and cause deformation of the sealing ring.

[0013] Preferably, one end of the transmission tube away from the hydraulic telescopic rod is connected to the outer wall of the sliding plate, and the outer wall of the driving tube is rotatably connected to the inside of the threaded tube.

[0014] The present invention has the following beneficial effects:

[0015] (1) The present invention aims to solve the problem of slight deformation of the sealing ring due to hard contact. A driving mechanism and a knocking mechanism are arranged inside the device. Before use, the bearing is placed on the top of the base, and then the staff places the sealing ring inside the bearing. Then the power of the electric telescopic rod and the motor is turned on. The electric telescopic rod forces the mounting plate and the knocking rod to move downward, and forces the knocking rod to enter the inner wall of the sealing ring, presenting a Figure 1 At this time, the motor drives the top fixed column and the fixed plate to rotate through the driving tube, and the rotating fixed plate will drive the inclined groove to rotate synchronously. During the rotation of the fixed plate, the bottom of the fixed plate will contact the outer wall of the ball, and force the ball to drive the prying rod to rotate downward. When the end of the prying rod close to the ball rotates downward, the end of the prying rod close to the knocking block will tilt upward, presenting a Figure 8 The state of middle H, and spring 2 is pulled at this time and accumulates mechanical power. When the inclined groove reaches the top of the ball, the ball loses the restriction of the bottom of the fixed plate. At this time, spring 2 will release mechanical power, forcing the prying rod to drive the knocking block to swing downward, and hit the top of the bearing rod through the knocking block. The bearing rod transmits the compressed force to the top of the sealing ring through the knocking rod, so that the sealing ring is pressed into the bearing. Through the application of the above components, the force of the hard collision between the sealing ring and the hammer is reduced, and the deformation of the sealing ring under pressure is reduced.

[0016] (2) The present invention utilizes the characteristics of the knocking block knocking the bearing rod, and two inclined grooves are arranged inside the device, and the two inclined grooves are in a diagonal state on the fixed plate. When the inclined grooves rotate, when the two inclined grooves reach the top of the corresponding ball, the corresponding knocking block will knock downward, presenting a Figure 8The two diagonal knocking blocks apply downward pressure, which will force the diagonal knocking rods to apply equal pressure to the top of the sealing ring. Through the application of the above components, the knocking area is dispersed to ensure that the knocking force on each position of the sealing ring is equal, avoiding unidirectional knocking of the knocking blocks, which may cause the sealing ring to tilt.

[0017] (3) The present invention utilizes the characteristic that the sealing ring is mostly formed into a circular ring shape, and an adjustment component is arranged inside the device. When the motor drives the driving tube and the fixed rod to rotate, during the rotation of the fixed rod, the spring telescopic rod 2 will force the inclined slider to be tightly attached to the inside of the arc groove, presenting a Figure 7 In the state shown, the driving tube rotates counterclockwise at this time, and the threaded tube will be driven to rotate through the inclined slider. The rotation of the threaded tube will force the threaded block to have a downward trend. The downward-moving threaded block drives one end of the outer support rod to move downward through the hydraulic telescopic rod, while the other end of the outer support rod cannot move downward due to the influence of the square slide. Therefore, the outer support rod will force the square slide and the knocking rod to expand outward, so that the outer walls of the multiple knocking rods are tightly attached to the inner wall of the sealing ring. Through the application of the above-mentioned components, the multiple knocking rods can be adjusted according to the size of the sealing ring, so that the equipment can adapt to sealing rings of different specifications and sizes, thereby improving the scope of application of the equipment.

[0018] (4) The present invention utilizes the characteristic that the above-mentioned outer support rod drives the knocking rod to support outward, and an adjustment component is arranged inside the equipment. When the knocking rod cannot continue to move outward, the outer support rod is blocked and will compress the hydraulic telescopic rod one, so that the internal liquid of the hydraulic telescopic rod one is transmitted to the inside of the liquid storage tank through the transmission pipe. The liquid inside the liquid storage tank forces the hydraulic telescopic rod two to extend, driving the outer wall of the contact slide rail to contact the outer wall of the sealing ring, and the two contact slide rails will clamp and restrict the inner wall of the sealing ring when they are stretched outward. Through the application of the above-mentioned components, it is avoided that when the knocking block knocks the knocking rod, there is an excessive separation distance between the bottom of the knocking rod and the outer wall of the sealing ring, resulting in the bottom of the knocking rod and the outer wall of the sealing ring being separated during subsequent knocking. The distance is too large, resulting in slight deformation of the outer wall of the sealing ring; in addition, as the knocking rod is close to the inner wall of the sealing ring, the knocking rod and the square slide cannot move outward, which will limit the further downward movement of the threaded block. When the threaded block can no longer move downward, the resistance to the rotation of the threaded tube will gradually increase. As the resistance of the threaded tube increases, the inclined slider will slide along the inner wall, causing the drive tube to rotate along the threaded tube. Through the application of the above-mentioned components, the threaded block will no longer drop after the knocking rod is close to the outer wall of the sealing ring, thereby preventing the outer support rod from expanding outward during the subsequent knocking process of the equipment, causing the knocking rod to excessively squeeze the sealing ring and cause deformation of the sealing ring.

[0035] The driving mechanism 2 includes a driving tube 21 fixedly connected to the output shaft of the motor 14, a fixing rod 22 fixedly connected to the inner wall of the driving tube 21, a spring telescopic rod 23 fixedly connected to the side wall of the fixing rod 22, an inclined slider 24 fixedly connected to the end of the spring telescopic rod 23 away from the fixing rod 22, an outer wall of the inclined slider 24 is slidably connected to the through hole of the driving tube 21, a fixing column 25 fixedly connected to the top of the driving tube 21, a fixing plate 26 fixedly connected to the top of the fixing column 25, an electric telescopic rod 27 rotatably connected to the top of the fixing plate 26, an end of the electric telescopic rod 27 away from the fixing plate 26 is fixedly connected to the bottom of the mounting bracket 11, and two inclined grooves 28 are provided on the side wall of the fixing plate 26;

[0036] The knocking mechanism 3 includes a telescopic rod 31 fixedly connected to the outer wall of the mounting plate 13, the end of the telescopic rod 31 away from the mounting plate 13 is fixedly connected to a square slide 32, the inner wall of the square slide 32 is slidably connected to a knocking rod 33, the top of the knocking rod 33 is fixedly connected to a bearing rod 35, the bottom of the bearing rod 35 is fixedly connected to a spring 34, the top of the mounting plate 13 is fixedly connected to a fixed bracket 36, the end of the fixed bracket 36 away from the mounting plate 13 is rotatably connected to a prying rod 37, the side wall of the prying rod 37 is fixedly connected to a knocking block 38, the prying rod 37 away from the knocking block 3 One end of 8 is rotatably connected to a ball 39, a spring 2 310 is fixedly connected to the side wall of the fixed bracket 36, and an adjusting component 4 is threadedly connected to the outer wall of the threaded tube 16. In order to solve the problem that the sealing ring is slightly deformed due to hard contact, a driving mechanism 2 and a knocking mechanism 3 are arranged inside the device. Before use, the bearing is placed on the top of the base 1, and then the staff places the sealing ring inside the bearing, and then the power of the electric telescopic rod 27 and the motor 14 is turned on. The electric telescopic rod 27 forces the mounting plate 13 and the knocking rod 33 to move downward, and forces the knocking rod 33 to enter the inner wall of the sealing ring, presenting as shown Figure 1 , at this time, the motor 14 drives the top fixed column 25 and the fixed plate 26 to rotate through the driving tube 21, and the rotating fixed plate 26 will drive the inclined groove 28 to rotate synchronously. During the rotation of the fixed plate 26, the bottom of the fixed plate 26 will contact the outer wall of the ball 39, and force the ball 39 to drive the prying rod 37 to rotate downward. When the end of the prying rod 37 close to the ball 39 rotates downward, the end of the prying rod 37 close to the knocking block 38 will tilt upward, presenting a Figure 8 The state of middle H, and the spring 2 310 is pulled at this time and accumulates mechanical power. When the inclined groove 28 reaches the top of the ball 39, the ball 39 loses the restriction of the bottom of the fixed plate 26. At this time, the spring 2 310 will release the mechanical power, forcing the prying rod 37 to drive the knocking block 38 to swing downward, and hit the top of the bearing rod 35 through the knocking block 38. The bearing rod 35 transmits the compressed force to the top of the sealing ring through the knocking rod 33, so that the sealing ring is pressed into the inside of the bearing. Through the application of the above components, the force of the hard collision between the sealing ring and the hammer is reduced, and the deformation of the sealing ring under pressure is reduced.

[0037] For example 2, please refer to Fig. 9 - Fig.11The present invention is a hydraulic assembly device for a bearing oil seal of a reducer. On the basis of the first embodiment, one end of the second spring 310 away from the fixed bracket 36 is fixedly connected to the side wall of the prying rod 37, and one end of the first spring 34 away from the bearing rod 35 is fixedly connected to the top of the square slide 32. By utilizing the characteristics of the knocking block 38 knocking the bearing rod 35, two inclined grooves 28 are arranged inside the device, and the two inclined grooves 28 are in a diagonal state on the fixed plate 26. When the inclined grooves 28 rotate, when the two inclined grooves 28 reach the top of the corresponding ball 39, the corresponding knocking block 38 will knock downward, presenting the following Figure 8 In the state of G and F, the two diagonal knocking blocks 38 apply downward pressure, which will force the diagonal knocking rods 33 to apply equal pressure to the top of the sealing ring. Through the application of the above components, the knocking area is dispersed to ensure that the knocking force on each position of the sealing ring is equal, avoiding unidirectional knocking of the knocking block 38, which causes the sealing ring to tilt.

[0038] The adjustment assembly 4 includes a threaded block 41 threadedly connected to the outer wall of the threaded tube 16 , a plurality of grooves 42 are formed on the outer wall of the threaded block 41 , and a hydraulic telescopic rod 43 is fixedly connected to the inner walls of the plurality of grooves 42 .

[0039] The adjusting assembly 4 also includes an outer support rod 44 fixedly connected to the other end of the hydraulic telescopic rod 1 43, and the end of the outer support rod 44 away from the hydraulic telescopic rod 1 43 is rotatably connected to the outer wall of the square slide 32. By utilizing the characteristic that the sealing ring is mostly formed in a circular ring shape, an adjusting assembly 4 is arranged inside the device. When the motor 14 drives the driving tube 21 and the fixed rod 22 to rotate, during the rotation of the fixed rod 22, the spring telescopic rod 23 will force the inclined slide 24 to be tightly attached to the inside of the arc groove 17, presenting a Figure 7 In the state shown, the driving tube 21 rotates counterclockwise, and the threaded tube 16 is driven to rotate through the inclined slider 24. The rotation of the threaded tube 16 will force the threaded block 41 to have a downward trend. The downwardly moving threaded block 41 drives one end of the outer support rod 44 to move downward through the hydraulic telescopic rod 43, while the other end of the outer support rod 44 cannot move downward due to the influence of the square slide 32. Therefore, the outer support rod 44 will force the square slide 32 and the knocking rod 33 to expand outward, so that the outer walls of the multiple knocking rods 33 are tightly attached to the inner wall of the sealing ring. Through the application of the above-mentioned components, the multiple knocking rods 33 can be adjusted according to the size of the sealing ring, so that the equipment can adapt to sealing rings of different specifications and sizes, thereby improving the scope of application of the equipment.

[0040] The adjusting assembly 4 also includes a transmission pipe 45 fixedly connected to the outer wall of the hydraulic telescopic rod 43, a sliding plate 46 is slidably connected to the outer wall of the knocking rod 33, and the bottom of the sliding plate 46 is connected through two liquid storage tanks 47. By utilizing the characteristics of the outer support rod 44 driving the knocking rod 33 to support outward, an adjusting assembly 4 is arranged inside the equipment. When the knocking rod 33 cannot continue to move outward, the outer support rod 44 is blocked and will compress the hydraulic telescopic rod 43, so that the liquid inside the hydraulic telescopic rod 43 is transmitted to the liquid storage tank 47 through the transmission pipe 45. Internally, the liquid in the liquid storage tank 47 forces the hydraulic telescopic rod 48 to extend, driving the outer wall of the contact slide rail 49 to contact the outer wall of the sealing ring, and the two contact slide rails 49 will clamp and restrict the inner wall of the sealing ring when they are stretched outward. Through the application of the above-mentioned components, it is avoided that when the knocking block 38 knocks the knocking rod 33, there is too much separation distance between the bottom of the knocking rod 33 and the outer wall of the sealing ring, resulting in excessive separation between the bottom of the knocking rod 33 and the outer wall of the sealing ring during subsequent knocking, causing slight deformation of the outer wall of the sealing ring.

[0041] The adjustment assembly 4 also includes a hydraulic telescopic rod 48 that is connected to the side wall of the liquid storage tank 47 , and one end of the hydraulic telescopic rod 48 away from the liquid storage tank 47 is slidably connected to a contact slide rail 49 .

[0042] The adjusting component 4 also includes a spring three 410 fixedly connected to the side wall of the contact slide rail 49, and the other end of the spring three 410 is fixedly connected to the outer wall of the hydraulic telescopic rod two 48. As the knocking rod 33 is tightly attached to the inner wall of the sealing ring, the knocking rod 33 and the square slide cylinder 32 cannot move outward, which will limit the continued downward movement of the threaded block 41. When the threaded block 41 can no longer move downward, the resistance to the rotation of the threaded tube 16 will gradually increase. As the resistance of the threaded tube 16 increases, the inclined slider 24 will slide along the inner wall of 17, so that the driving tube 21 rotates along the threaded tube 16. Through the application of the above-mentioned components, after the knocking rod 33 is tightly attached to the outer wall of the sealing ring, the threaded block 41 will no longer descend, thereby preventing the outer support rod 44 from expanding outward during the subsequent knocking process of the equipment, causing the knocking rod 33 to excessively squeeze the sealing ring and cause deformation of the sealing ring.

[0043] One end of the transmission tube 45 away from the hydraulic telescopic rod 43 is connected to the outer wall of the sliding plate 46 , and the outer wall of the driving tube 21 is rotatably connected to the inside of the threaded tube 16 .

[0044] A specific application of this embodiment is: before use, the bearing is placed on the top of the base 1, and then the staff places the sealing ring inside the bearing, and then the power of the electric telescopic rod 27 and the motor 14 is turned on, and the electric telescopic rod 27 forces the mounting plate 13 and the knocking rod 33 to move downward, and forces the knocking rod 33 to enter the inner wall of the sealing ring, presenting as shown Figure 1, at this time, the motor 14 drives the top fixed column 25 and the fixed plate 26 to rotate through the driving tube 21, and the rotating fixed plate 26 will drive the inclined groove 28 to rotate synchronously. During the rotation of the fixed plate 26, the bottom of the fixed plate 26 will contact the outer wall of the ball 39, and force the ball 39 to drive the prying rod 37 to rotate downward. When the end of the prying rod 37 close to the ball 39 rotates downward, the end of the prying rod 37 close to the knocking block 38 will tilt upward, presenting a Figure 8 The state of middle H, and the spring 2 310 is pulled at this time and accumulates mechanical power. When the inclined groove 28 reaches the top of the ball 39, the ball 39 loses the restriction of the bottom of the fixed plate 26. At this time, the spring 2 310 will release the mechanical power, forcing the prying rod 37 to drive the knocking block 38 to swing downward, and hit the top of the bearing rod 35 through the knocking block 38. The bearing rod 35 transmits the compressed force to the top of the sealing ring through the knocking rod 33, so that the sealing ring is pressed into the inside of the bearing. Through the application of the above components, the force of the hard collision between the sealing ring and the hammer is reduced, and the deformation of the sealing ring under pressure is reduced.

[0045] Taking advantage of the above-mentioned characteristics of the knocking block 38 knocking the bearing rod 35, two inclined grooves 28 are arranged inside the device, and the two inclined grooves 28 are in a diagonal state on the fixed plate 26. When the inclined grooves 28 rotate, when the two inclined grooves 28 reach the top of the corresponding ball 39, the corresponding knocking block 38 will knock downwards, presenting a Figure 8 In the state of G and F, the two diagonal knocking blocks 38 apply downward pressure, which will force the diagonal knocking rods 33 to apply equal pressure to the top of the sealing ring. Through the application of the above components, the knocking area is dispersed to ensure that the knocking force on each position of the sealing ring is equal, avoiding unidirectional knocking of the knocking block 38, which causes the sealing ring to tilt.

[0046] Taking advantage of the fact that the sealing ring is mostly formed into a circular ring, an adjusting component 4 is arranged inside the device. When the motor 14 drives the driving tube 21 and the fixing rod 22 to rotate, during the rotation of the fixing rod 22, the spring telescopic rod 23 will force the inclined slider 24 to be closely attached to the inside of the arc groove 17, presenting a Figure 7 In the state shown, the driving tube 21 rotates counterclockwise, and the threaded tube 16 is driven to rotate through the inclined slider 24. The rotation of the threaded tube 16 will force the threaded block 41 to have a downward trend. The downwardly moving threaded block 41 drives one end of the outer support rod 44 to move downward through the hydraulic telescopic rod 43, while the other end of the outer support rod 44 cannot move downward due to the influence of the square slide 32. Therefore, the outer support rod 44 will force the square slide 32 and the knocking rod 33 to expand outward, so that the outer walls of the multiple knocking rods 33 are tightly attached to the inner wall of the sealing ring. Through the application of the above-mentioned components, the multiple knocking rods 33 can be adjusted according to the size of the sealing ring, so that the equipment can adapt to sealing rings of different specifications and sizes, thereby improving the scope of application of the equipment.

[0047] By utilizing the characteristic that the outer support rod 44 drives the knocking rod 33 to support outward, an adjusting component 4 is provided inside the device. When the knocking rod 33 cannot continue to move outward, the outer support rod 44 is blocked and will compress the hydraulic telescopic rod 1 43, so that the internal liquid of the hydraulic telescopic rod 1 43 is transmitted to the inside of the liquid storage tank 47 through the transmission pipe 45. The internal liquid of the liquid storage tank 47 forces the hydraulic telescopic rod 2 48 to extend, driving the outer wall of the contact slide rail 49 to contact the outer wall of the sealing ring, and the two contact slide rails 49 will clamp and restrict the inner wall of the sealing ring when they are stretched outward. By using the above-mentioned components, it is avoided that when the knocking block 38 knocks the knocking rod 33, there is an excessive separation distance between the bottom of the knocking rod 33 and the outer wall of the sealing ring, resulting in a small distance between the bottom of the knocking rod 33 and the outer wall of the sealing ring during subsequent knocking. The distance is too large, resulting in slight deformation of the outer wall of the sealing ring; in addition, as the knocking rod 33 is tightly attached to the inner wall of the sealing ring, the knocking rod 33 and the square slide 32 cannot move outward, which will limit the continued downward movement of the threaded block 41. When the threaded block 41 can no longer move downward, the resistance to the rotation of the threaded tube 16 will gradually increase. As the resistance of the threaded tube 16 increases, the inclined slider 24 will slide along the inner wall of 17, causing the drive tube 21 to rotate along the threaded tube 16. Through the application of the above-mentioned components, after the knocking rod 33 is tightly attached to the outer wall of the sealing ring, the threaded block 41 will no longer descend, thereby preventing the outer support rod 44 from expanding outward during the subsequent knocking process of the equipment, causing the knocking rod 33 to excessively squeeze the sealing ring and cause deformation of the sealing ring.
