DETAILED DESCRIPTION

[0022] The following is combined with Figure 1-8 , and further illustrate the technical solution of the present invention through specific implementation methods.

The opening diameters of the two ends of the shot blasting nozzle 114 are different, and the position between the two openings is narrowed to increase the flow rate of air. The accelerating pneumatic tube 111 is fixedly connected with a valve body 113 in the radial direction, and a funnel 116 is installed and connected on the valve body 113. A rotating column 109 is rotatably installed inside the valve body 113, and a leakage hole 119 is provided on the rotating column 109 to cut off or connect the funnel 116 and the internal space of the accelerating pneumatic tube 111. The air pump 105 is fixedly installed on the air pump bracket 104, and the air pump bracket 104 is fixedly installed on the extension bracket 102. The air pump bracket 104 is located at the air inlet of the air pump 105 and is rotatably installed with a pneumatic impeller 107. The air pump bracket 104 is fixedly installed with a gearbox 106, and the input shaft of the gearbox 106 and the pneumatic impeller 107 are connected by a first transmission belt 115. A reinforcing frame 110 is also fixedly mounted on the valve body 113. The reinforcing frame 110 is used to support the rotating shaft of the rotating column 109. The output shaft of the gearbox 106 is connected to the rotating shaft of the rotating column 109 through the second transmission belt 108. A rotation limit ring 130 is fixedly mounted on the end of each pull rod 118 away from the hook 129. A slave pulley 112 is provided on each pull rod 118 through a spline sliding sleeve. The slave pulley 112 is rotatably mounted on the clamping frame 120. A rotating motor 121 is fixedly mounted on the side of the clamping frame 120. The output shaft of the rotating motor 121 protrudes forward and backward. The two ends of the output shaft of the rotating motor 121 are connected to the two slave pulleys 112 through the third transmission belt 122. A guide slide 123 is also fixedly installed on the clamping frame 120, and an adjustment pull rod arm 124 is slidably installed on the guide slide 123. There are two adjustment pull rod arms 124, and the two adjustment pull rod arms 124 are symmetrically arranged on both sides of the clamping frame 120, wherein one end of the adjustment pull rod arm 124 is rotationally matched with the pull rod 118 through a rotating limit ring 130.A clamping motor 128 is also fixedly mounted on the clamping frame 120, and a screw rod 127 is fixedly mounted on the output shaft of the clamping motor 128. A nut connecting block 126 is threadedly sleeved on the screw rod 127. The nut connecting block 126 is movably connected to the two adjusting tie rod arms 124 via two adjusting connecting rods 125, so as to drive the two adjusting tie rod arms 124 to move relative to each other.

[0024] The working principle of the stainless steel surface shot peening equipment disclosed in the present invention is as follows: a hanging ear is arranged on the workpiece to be shot peened, and the hanging ear is hooked by two hooks 129 to fix the workpiece. The funnel 116 is provided with steel shots. When working, the electromagnet 117 and the air pump 105 are started. When the air pump 105 is started, the external air is blown into the accelerating pneumatic tube 111 at a high speed, so that a high-speed airflow is generated in the accelerating pneumatic tube 111, and the air is accelerated through the shot blasting nozzle 114. At the same time, the air flowing through the air inlet of the air pump 105 drives the pneumatic impeller 107 to rotate. The rotation of the pneumatic impeller 107 drives the input shaft of the gearbox 106 to rotate through the first transmission belt 115. The output shaft of the gearbox 106 drives the rotating column 109 to rotate through the second transmission belt 108. The rotation of the rotating column 109 causes the leakage through hole 119 to rotate. At this time, the valve body 113 will continuously open and close the connection between the accelerating pneumatic tube 111 and the inside of the funnel 116, so that the steel shots will intermittently enter the accelerating pneumatic tube 111, so that the air can act on the steel shots more effectively, providing power for the steel shots.

[0025] When the steel shot is ejected from the shot blasting nozzle 114, it will enter the magnetic constraint range of the electromagnet 117. Under the attraction of the electromagnet 117, the steel shot will be subjected to a magnetic force toward the workpiece, so that the speed of the steel shot will continue to increase. At this time, the steel shot will be subjected to the dual effects of the driving force of the air and the attraction of the electromagnet 117, thereby greatly increasing the kinetic energy of the steel shot, so that the rotation speed of the impeller inside the air pump 105 can be reduced as much as possible, and the working noise of the air pump 105 can be reduced. At the same time, a rubber pad is set on the surface of the electromagnet 117, so that the sound of the steel shot hitting the electromagnet 117 can be reduced. In this process, the rotating motor 121 is started, and the output shaft of the rotating motor 121 drives the belt pulley 112 to rotate through the third transmission belt 122. The rotation of the belt pulley 112 will drive the pull rod 118 to rotate, thereby driving the workpiece on the hook 129 to rotate, so that the surfaces of different positions of the workpiece face the flow direction of the steel shot.

[0026] Through the clamping motor 128, the output shaft of the clamping motor 128 drives the screw rod 127 to rotate, and the screw rod 127 drives the two adjusting pull rod arms 124 to move relative to each other through the nut connecting block 126 and the adjusting connecting rod 125. Since the pull rod 118 is rotatably installed on the adjusting pull rod arm 124, the distance between the two hooks 129 can be controlled by the clamping motor 128, so as to clamp workpieces of different sizes.

[0027] It is necessary to regularly cut off the power to the electromagnet 117 and the air pump 105. At this time, the electromagnet 117 will lose its magnetic force. After losing its magnetic force, the restraining force of the electromagnet 117 on the steel shot will also disappear. At this time, the steel shot will fall onto the sliding collection plate 103 under the action of gravity, roll down the sliding collection plate 103 to the recovery mechanism, and then re-enter the funnel 116 to recycle the steel shot and reduce the consumption of steel shot. The clamping frame 120 is fixed on the inner wall of the protective shell 101, and a shielding plate is provided on the outer side of the clamping frame 120 to prevent the high-speed moving steel shot from damaging the components on the clamping frame 120.
