The shot is unevenly distributed in the pipe, resulting in differences in the number and velocity of shot received at different locations on the pipe surface, leading to inconsistent strengthening effects. Furthermore, the pipe fixing devices in traditional shot peening equipment are rudimentary and prone to displacement and shaking under the impact of shot peening, affecting the shot peening accuracy and reducing the strengthening quality.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0025] Please see Figures 1-7 This utility model discloses a surface strengthening treatment device for titanium alloy pipes, including an operating table 1 and a shot trough 2 disposed on one side of the operating table 1, and also includes an automatic pipe clamping assembly 3, a shot homogenization and distribution assembly 4, a pipe rotation assembly 5, a pipe pushing assembly 6, and a support assembly 7, wherein:

[0026] The operating table 1 is equipped with a slide 11 and a control console 14. A protective cover 12 is provided on one side of the slide 11, and a discharge port 21 is provided in the shot trough 2.

[0027] Please refer to the appendix. Figure 3 The automatic pipe clamping assembly 3 includes a clamping back plate 31. A motor 32 is fixed to one side of the clamping back plate 31 by bolts. One end of the motor 32 is connected to a horizontally arranged main bevel gear 33. The main bevel gear 33 is fitted with a vertically arranged secondary bevel gear 34 and rotates in cooperation. The secondary bevel gear 34 is welded to a bidirectional spiral shaft 35. The clamping frames 36 are fitted at both ends of the bidirectional spiral shaft 35 and rotate in cooperation.

[0028] Please refer to the appendix. Figure 4 The shot homogenization and distribution component 4 includes a feed hopper 41, which is connected to a main pipe 42 via a flange. One side of the main pipe 42 is connected to an airflow equalization pipe 43 via a flange. A vibration motor 44 is fixed to the bottom of the shot trough 2 with screws. Specifically, the airflow equalization pipe 43 can make the shot falling from the feed hopper 41 receive uniform airflow thrust, ensuring stable and continuous material conveying. At the same time, it can make the airflow evenly distributed on the cross section of the conveying pipe 47, thereby making the shot evenly distributed in the pipe, ensuring stable shot peening intensity and coverage.

[0029] The feed hopper 41 is located below the discharge port 21. Several springs 45 are provided at the bottom of the shot trough 2. One side of the airflow equalization pipe 43 is connected to the Roots blower 46 through a flange. One end of the main pipe 42 is connected to the centrifugal shot blaster 48 through the conveying pipe 47. Specifically, the vibration motor 44 causes the shot trough 2 to vibrate continuously with the cooperation of the springs 45, thereby making the recovered shot evenly distributed and further improving the uniformity of shot distribution in the conveying pipe 47.

[0030] In this embodiment, the control console 14 controls the motor 32 to drive the secondary bevel gear 34 to rotate, which in turn drives the main bevel gear 33 to rotate. The main bevel gear 33 drives the bidirectional spiral shaft 35 to interact with the clamping frame 36. Under the action of the spiral force, the clamping frame 36 slides on the clamping back plate 31 and moves closer to the pipe 8 from both sides, and finally clamps the pipe 8 appropriately. Under the precise control of the control console 14, the clamping is more stable and the shot peening quality is higher. Example 2

[0031] Based on the above embodiment 1, please refer to the appendix. Figure 5 , Figure 6 as well as Figure 7The centrifugal shot blaster 48 is fixed to the top of the inner side of the protective cover 12 by screws. A pipe 8 is provided below the centrifugal shot blaster 48. One end of the pipe 8 abuts against the support plate 71, and the other end abuts against the clamping frame 36 on both sides. The clamping frame 36 is fitted into and slides against the back plate 31. Specifically, the support plate 71 plays the role of supporting the pipe 8 to resist the impact of shot blasting and maintain the stability of the pipe 8.

[0032] The support component 7 includes a support sleeve 72, which is fitted into and slidably engaged with a support column 73. The support column 73 is provided with a plurality of insertion holes 731, and a pin 74 is inserted through the support sleeve 72. The pin 74 passes through the insertion holes 731 and is slidably engaged.

[0033] The support plate 71 is fixed to the top of the support column 73 by screws, and the support sleeve 72 is fixed to the top surface of the operating table 1 by bolts. The support sleeve 72 has an inclined slide 13 on one side. Specifically, the used projectiles are bounced back by the protective cover 12 and fall into the inclined slide 13, and fall back into the projectile groove 2 under the action of gravity for continued use.

[0034] The pipe rotation assembly 5 includes a servo motor 51. One end of the servo motor 51 is connected to an encoder 52 via a coupling. The encoder 52 is fixed to a straight rod 54 via a connecting bracket 53. One end of the straight rod 54 is welded to a clamping back plate 31.

[0035] The pipe propulsion assembly 6 includes a slide 61, a servo motor 51 fixed above the slide 61, a chain 62 fixedly connected to the bottom of the slide 61, and symmetrically arranged gears 63 fitted at both ends of the chain 62. One of the gears 63 is fixedly connected to a power motor 64. The bottom end of the slide 61 is fitted with a sliding groove 11 and slides in a sliding fit.

[0036] In this embodiment, the servo motor 51 drives the encoder 52 to rotate through the coupling. The encoder 52 obtains the actual speed information of the motor by measuring the number of rotations of the motor shaft per unit time and feeds it back to the control console 14. The control console 14 controls the driver of the servo motor 51 to compare the actual speed with the given speed, and then adjusts the motor drive signal to ensure that the servo motor 51 rotates at a uniform speed, ensuring that the shot peening time of each part of the pipe 8 is consistent and improving the uniformity of surface strengthening.

[0037] The working principle and usage process of this utility model are as follows: First, one end of the pipe 8 is passed through the protective cover 12 and placed on the support plate 71, and the other end is placed between the clamping frames 36. The outer diameter parameters of the pipe 8 are input using the control console 14. The control console 8 starts the motor 32 according to the input parameters, which drives the secondary bevel gear 34 to rotate, and then drives the main bevel gear 33 to rotate. The main bevel gear 33 drives the bidirectional spiral shaft 35 to interact with the clamping frame 36. Under the action of the spiral force, the clamping frame 36 slides on the clamping back plate 31 and moves closer to the pipe 8 from both sides, and finally clamps the pipe 8 appropriately and stably, realizing the automatic clamping of the pipe.

[0038] Then, based on the clamping height of the pipe 8, the height of the support column 73 is adjusted, and the support column 73 is fixed in the support sleeve 72 by inserting the pin 74 into the insertion hole 731, so that the height of the support plate 71 just touches the bottom of the pipe 8 to form support, so that the pipe 8 will not shake or shift under the impact of shot peening, thus affecting the shot peening accuracy.

[0039] Then, the Roots blower 46 and the vibratory motor 44 are started. The Roots blower 46 generates airflow, which passes through the airflow equalization pipe 43 to obtain balanced airflow, and then reaches the main pipe 42. The shot in the shot trough 2 collides and moves with each other under the action of the vibratory motor 44, thereby changing its position and finally achieving a relatively uniform distribution state. It then leaks from the discharge port 21 into the feed funnel 41 and finally falls into the main pipe 42. The airflow passing through the main pipe 42 is evenly carried into the conveying pipe 47. The conveying pipe 47 conveys the shot to the centrifugal shot blaster 48. Under the centrifugal force of the centrifugal wheel inside the centrifugal shot blaster 48, the pipe 8 is shot blasted and strengthened.

[0040] At this time, the power motor 64 and the servo motor 51 are started simultaneously. The servo motor 51 drives the straight rod 54 to rotate, which in turn drives the pipe 8 held on the clamping back plate 31 to rotate at a constant speed. At the same time, the power motor 64 drives the gear 63 to rotate, which in turn drives the slide 61 on the chain 62 to slide in the slide groove 11. The slide 61 drives the pipe 8 to be pushed into the protective cover 12 at a constant speed, so that the outer surface of the pipe 8 is fully shot peened.
