[0057] Please refer to Figure 1-Figure 3 The present embodiment provides a steel spare part surface strengthening and repairing device 100, which includes a main body 110, a loading platform 120, a clamping assembly 130, a powder distribution assembly 140 and a laser repair unit 150;

[0058] The main body 110 is provided with a processing inner cavity 111; the loading platform 120 is rotatably disposed in the processing inner cavity 111 and is used to place the steel spare part 10; the clamping assembly 130 is connected to the main body 110 and is used to clamp the steel spare part 10 located on the loading platform 120;

[0059] The powder distribution component 140 and the laser repair unit 150 can be movably arranged in the processing cavity 111. The powder distribution component 140 is used to distribute iron powder on the surface of the steel spare part 10 located on the loading platform 120; the laser repair unit 150 is used to emit laser light toward the area of ​​the steel spare part 10 where the iron powder is distributed, so as to strengthen or repair the surface of the steel spare part 10.

[0060] Please refer to Figure 1-Figure 3 The working principle of the steel spare parts surface strengthening and repairing device 100 is:

[0061] The steel spare part surface strengthening and repairing device 100 comprises a main body 110, a loading platform 120, a clamping assembly 130, a powder distributing assembly 140 and a laser repairing unit 150;

[0062] The main body 110 is provided with a processing inner cavity 111, the purpose of which is to form an independent processing space, so as to prevent the processing process from being affected by the external environment, and at the same time, to prevent part of the exhaust gas from being leaked to the outside without being treated during the internal processing and repair process;

[0063] During processing, the loading platform 120 and the clamping assembly 130 are used together to complete the positioning and installation of the steel spare part 10 to be repaired in the processing inner cavity 111; wherein, since the loading platform 120 is rotatably arranged in the processing inner cavity 111, it can be rotated in the processing inner cavity 111 when placing the steel spare part 10, so that it is convenient to adjust the placement position of the steel spare part 10 on the loading platform 120, and its purpose is to facilitate it to adjust it to a proper position for subsequent powdering and laser processing; in addition, such a setting method can also reduce the requirements for the placement position of the steel spare part 10, thereby simplifying the placement of the steel spare part 10;

[0064] The powder distribution component 140 and the laser repair unit 150 can be movably arranged in the processing inner cavity 111. Therefore, in the process of arranging iron powder on the surface of the steel spare part 10 located on the loading platform 120 through the powder distribution component 140, and emitting laser light toward the area where the iron powder is distributed on the steel spare part 10 through the laser repair unit 150 to strengthen or repair the surface of the steel spare part 10, since the powder distribution component 140 and the laser repair unit 150 can move in the processing inner cavity 111, the flexibility of powder distribution and laser processing can be improved, so that the processing range can be larger, so that various types of steel spare parts 10 can be adapted. In addition, such a structural setting is conducive to realizing automated processing;

[0065] In summary, the surface strengthening and repairing device 100 for steel spare parts can simplify the operation, improve the efficiency and quality of strengthening and repairing the steel spare parts 10, and can reduce the labor intensity of the staff, which is conducive to reducing labor costs. It should be noted that in the above content, the rotation of the loading platform 120, the movement of the clamping assembly 130, the action of the powder distribution assembly 140 and the action of the laser repair unit 150 can all be electrically connected to the control system, thereby forming an automated processing and repair system, which is conducive to the degree of automation of the processing, thereby improving its repair efficiency.

[0066] It should also be noted that, in this embodiment, during the repair process, the laser repair unit 150 can also be used to preheat the steel spare part 10. The purpose is to heat the steel spare part 10 before laser processing, thereby reducing the temperature difference between the processed surface and the rest of the steel spare part 10, thereby avoiding corresponding defects in the steel parts due to temperature differences, thereby improving the processing quality.

[0067] Please refer to Figure 1-Figure 4When configuring the loading platform 120, the loading platform 120 used in this embodiment includes a rotating placement plate 121 and a driving motor 122. The rotating placement plate 121 is rotatably arranged in the processing cavity 111 and is used to place the steel spare parts 10; the driving motor 122 is connected to the main body 110 and is located outside the main body 110, and is used to drive the rotating placement plate 121 to rotate. In this arrangement, the driving motor 122 can be arranged outside the main body 110, thereby avoiding that it is located in the processing cavity 111 and causing the space of the processing cavity 111 to be reduced. It should also be noted that since waste slag may be generated during the processing, and when the powder is sprinkled, some iron powder may fall to the bottom of the main body 110, in order to prevent the waste slag and iron powder from affecting the rotation of the loading platform 120, a cover body 123 is provided on the outer periphery of the rotating placement plate 121, the purpose of which is to prevent the waste slag and iron powder from entering the rotation gap of the rotating placement plate 121.

[0068] Please refer to Figure 1-Figure 5 , and when the clamping assembly 130 is configured, its function is to clamp the steel spare part 10 placed on the rotating placement disk 121, so the clamping assembly 130 includes two clamping units 131, and the two clamping units 131 are respectively arranged on the opposite side walls of the main body 110; that is, the present embodiment adopts the method of clamping the two clamping units 131 on the opposite sides of the steel spare part 10 to achieve clamping; specifically, each clamping unit 131 includes a driving cylinder 132, a movable seat 133, a clamping cylinder 134 and a clamping seat 135; the driving cylinder 132 is connected to the side wall of the main body 110, and is in transmission connection with the movable seat 133 located in the processing inner cavity 111; the clamping cylinder 134 is connected to the movable seat 133, and is in transmission connection with the clamping seat 135;

[0069] Among them, the driving cylinder 132 is used to drive the movable seat 133 and the clamping cylinder 134 and the clamping seat 135 connected to the movable seat 133 to move toward the steel spare part 10; the clamping cylinder 134 is used to drive the clamping seat 135 to move toward the steel spare part 10 to abut against the steel spare part 10.

[0070] Therefore, when clamping the steel spare part 10, the movable seat 133 can be driven by the driving cylinder 132 to quickly approach the steel spare part 10, thereby driving the clamping seat 135 to move quickly, and then the clamping seat 135 can be driven by the clamping cylinder 134 to move accurately toward the direction of the steel spare part 10 to abut against the steel spare part 10, so that fast and large-stroke movement can be achieved by the driving cylinder 132, and slow adjustment can be achieved by the clamping cylinder 134 to improve the stability of clamping and reduce the impact force on the steel spare part 10; in addition, when configuring the clamping seat 135, it can be set as a single plate body according to needs; or according to use requirements, multiple clamping seats 135 and multiple clamping cylinders 134 can be set, each clamping cylinder 134 corresponds to driving a clamping seat 135 to move, and multiple clamping seats 135 are arranged at intervals, the purpose of which is to increase the contact points with the surface of the steel spare part 10 in this way to meet the clamping and positioning requirements of the special-shaped steel spare parts 10.

[0071] Based on the above structural setting, in order to facilitate heating of the steel spare part 10, thereby avoiding defects caused by temperature differences on the steel spare part 10, the laser repair unit 150 can preheat the steel spare part 10, and the side of the clamping seat 135 used to abut against the steel spare part 10 and the end of the loading platform 120 used to place the steel spare part 10 can also be provided with a heating plate 136, the purpose of which is to heat the steel spare part 10 by contacting the heating plate 136 with the steel spare part 10. It should be noted that the heating can be determined according to the processing requirements, and when heating, it can be achieved by the laser repair unit 150 and one or more of the multiple processing plates.

[0072] For further information, please refer to Figure 1 and Figure 2 In this embodiment, since there is iron powder sputtering during the powder sputtering process, and there may be some sputtering during the processing, in order to protect the powder distribution component 140 and the laser repair unit 150, and this embodiment adopts a method in which the powder distribution component 140 and the laser repair unit 150 are movably arranged in the main body 110, therefore, it is also possible to protect the structure of the movably arranged powder distribution component 140 and the laser repair unit 150. Therefore, the surface strengthening and repair device 100 for steel spare parts also includes an air curtain generator 160, the purpose of which is to separate the processing inner cavity 111, so as to avoid the sputtering from entering the powder distribution component 140 and the laser repair unit 150 and the structure of the movably arranged powder distribution component 140 and the laser repair unit 150 when the steel spare part 10 is powdered and laser processed in the lower half area. Specifically, the air curtain generator 160 is connected to one side wall of the main body 110, and is used to spray an air flow toward the other side wall opposite thereto to form an air curtain (such as Figure 1 and Figure 2As shown by arrow A), the air curtain separates the processing cavity 111 into a lower half 112 and an upper half 113;

[0073] The side wall of the main body 110 is provided with a guide portion 161, which is used to guide the airflow derived from the air curtain generator 160 to flow outward or toward the upper half 113. The guide portion 161 and the air curtain generator 160 are located on two opposite side walls of the main body 110;

[0074] The loading platform 120 and the clamping assembly 130 are both located in the lower part 112 , the powder distribution assembly 140 and the laser repair unit 150 are both located in the upper part 113 , and the powder distribution assembly 140 and the laser repair unit 150 can both move to the lower part 112 .

[0075] It should be noted that the above-mentioned structural setting can also play a role in isolating heat, the purpose of which is to prevent the upper part 113 from being affected by the heat generated by laser processing and causing malfunctions; and because the powder distribution component 140 and the laser repair unit 150 can be movably arranged in the processing cavity 111, they can move in the processing cavity 111, and after passing through the air curtain, they can sprinkle powder or laser process the surface of the steel spare part 10.

[0076] For further information, please refer to Figure 1-Figure 7 In this embodiment, it can be known from the above content that the powder distribution assembly 140 and the laser repair unit 150 in this embodiment can be movably arranged in the processing inner cavity 111, so that the surface strengthening and repairing device 100 for steel spare parts further includes a first linear motion module 171, a second linear motion module 172 and a third linear motion module 173;

[0077] The first linear motion module 171 is connected to the main body 110, the second linear motion module 172 and the third linear motion module 173 are both connected to the first linear motion module 171, and the first linear motion module 171 is used to drive the second linear motion module 172 and the third linear motion module 173 to move along the first direction;

[0078] The second linear motion module 172 is arranged in parallel with the third linear motion module 173, and the powder distribution assembly 140 and the laser repair unit 150 are connected to the second linear motion module 172 and the third linear motion module 173 respectively, the second linear motion module 172 is used to drive the powder distribution assembly 140 to move along the second direction, and the third linear motion module 173 is used to drive the laser repair unit 150 to move along the second direction;

[0079] The first direction is perpendicular to the second direction.

[0080] That is, through the setting of the above-mentioned first linear motion module 171, the second linear motion module 172 and the third linear motion module 173, the movement of the powder distribution assembly 140 and the laser repair unit 150 in the first direction and the second direction can be realized. It should be noted that the first direction and the second direction in this embodiment are both movements on the horizontal plane, and the third direction in the following text of this embodiment is the vertical direction; in addition, the above-mentioned first linear motion module 171, the second linear motion module 172 and the third linear motion module 173 can adopt the linear motion modules in the prior art. The purpose is to improve the motion accuracy and expand its range of activities through such a setting method, so as to improve the processing efficiency while facilitating the realization of automation.
