[0002] Aluminum die-cast parts are a common type of castings. Burrs will remain on their surface during the processing, resulting in poor quality of the parts. They cannot be directly put into storage or enter the next structural processing step. In order to ensure the smoothness of the die-casting surface, burrs need to be removed through deburring equipment. Existing deburring equipment mostly uses shot peening to deburr. However, when deburring, some burrs will be mixed with steel shots and recycled for secondary use. Due to the sharp burrs, the internal structure of the shot peening machine will be damaged, making it inconvenient to perform subsequent cleaning operations of steel shots and burr debris.

In addition to placing parts, abrasives can also be placed inside the roller 102, so that the parts inside the roller 102 can fully contact the abrasives to achieve a deburring effect. The shot peening machine 103 uses the impact of high-speed steel shot flow on the surface of the parts to generate a plastic cyclic strain layer on the surface, thereby causing a favorable change in the microstructure of the layer, thereby achieving a deburring effect. The shot peening machine 103 includes an electrical unit, a gas compression unit, a transition cabin, and a nozzle. The drum 102 is rotatably arranged inside the box 101, and the shot blasting machine 103 is arranged inside the drum 102. Both ends of the drum 102 are rotatably connected to the side plates 104. The side plates 104 and the box 101 can be connected through a connecting plate to increase the overall stability and play a fixing effect. An inlet and outlet 105 is arranged on one of the side plates 104 for placing parts to ensure the overall practicality of the equipment. A separation port 106 for discharging steel shots is arranged on one side of the bottom of the box 101 to facilitate the discharge of steel shots, so that the steel shots are in a circulating movement process, which is convenient for repeated operation, thereby increasing the contact time between the steel shots and the parts and increasing the deburring efficiency.

[0036] A conveying mechanism 200 is provided on one side of the box 101 near the separation port 106, which is used to return the steel shot to the inside of the shot peening machine 103 to wait for reuse. A moving mechanism 300 is provided inside the drum 102, which is used to adjust the steel shot launching position of the shot peening machine 103, change the steel shot spraying angle, and increase the contact range with the parts. A screening mechanism 400 for separating the steel shot from the burr and slag is provided below the drum 102, which is convenient for recovering the burr and slag.

[0037] The conveying mechanism 200 includes a collecting box 201 arranged at the separation port 106, and an inclined plate 202 is fixedly installed on the bottom wall of the collecting box 201 to prevent the steel balls from accumulating inside the collecting box 201 and failing to achieve the conveying effect. A screw conveyor 203 is fixedly installed on the upper end of the collecting box 201. The screw conveyor 203 is a common component in the field and will not be described in detail here. The screw conveyor 203 is connected to the collecting box 201, and the inclined plate 202 is inclined toward one side of the screw conveyor 203, so that the steel balls can roll to the bottom of the screw conveyor 203 through the inclined surface. The conveying pipe 204 is fixed on the top of the screw conveyor 203, and the other end of the conveying pipe 204 passes through the side plate 104 and extends to the inside of the drum 102, and the conveying pipe 204 is connected to the shot peening machine 103.

The first motor 302 is started to drive the reciprocating screw rod 301 to rotate, thereby driving the slider 305 and the shot peening machine 103 to move back and forth, so as to adjust the spraying position, increase the spraying range and area, and thereby enable the steel shot to fully contact the surface of the part, so as to facilitate the treatment. To deal with burrs on the surface of parts, the first motor 302 is fixedly connected to the box body 101 through the first bracket 303, which is convenient for fixing the position of the first motor 302.

The shot peening machine 103 is connected to the slider 305 through a swinging assembly. The spraying angle of the shot peening machine 103 is adjusted to increase the applicability effect.

[0039] Among them Figure 6 and Figure 7As shown, the swing assembly includes fixed rods 306 symmetrically installed on both sides of the shot peening machine 103 to increase the connection strength between the shot peening machine 103 and the slider 305.

The other end of the connecting rod 307 is rotatably connected to a rotating rod 308. The rotating rod 308 is fixedly connected to the output end of the second motor 309. The rotating rod 308 is driven to rotate by the second motor 309, and then the connecting rod 307 is driven to move, thereby realizing the angle offset operation of the fixed rod 306, thereby changing the spraying angle of the shot peening machine 103. The second motor 309 is fixedly connected to the slider 305 through the reinforcing rod to achieve a fixing effect.

[0040] Among them Figure 3 and Figure 8 As shown, limit blocks 310 are symmetrically installed on the reciprocating screw 301, and threads are arranged between the limit blocks 310, so as to limit the moving distance of the shot peening machine 103 to avoid interference with the inner wall of the drum 102. A guide rod 311 is arranged above the limit block 310 to play a guiding role, so that the slider 305 can move along the direction of the reciprocating screw 301. The guide rod 311 is fixedly connected to the inner wall of the side plate 104, and the guide rod 311 is slidably connected to the slider 305, so that the slider 305 can move smoothly.

[0041] Among them Figure 3-Figure 6 As shown, the screening mechanism 400 includes a symmetrically arranged support plate 401, and a screen plate 402 is placed on the upper surface of the support plate 401 located at the bottom, so that the steel shots and burr debris can pass through the screen plate 402, and the burr debris with a smaller volume can be screened out, so that the steel shots and burr debris can be collected separately. The support plate 401 located at the top is connected to the screen plate 402 by a spring, and the spring enables the screen plate 402 to automatically return to its original position. The other end of the screen plate 402 is rotatably connected to the inner wall of the box body 101, and the lowest end of the screen plate 402 is connected to the separation The position of the separation port 106 is adapted to facilitate the discharge of the separated steel shots through the separation port 106. A plurality of cams 403 are arranged below the sieve plate 402. The cams 403 are in contact with the sieve plate 402 and are not fixed. One end of the cam 403 shaft extends to the outside of the box body 101 and is fixedly connected to the output end of the third motor. The cam 403 shaft is rotatably connected to the inner wall of the box body 101. The third motor drives the cam 403 to rotate, so that the cam 403 can contact with the sieve plate 402, thereby driving the sieve plate 402 to move up and down, thereby achieving a screening effect.

[0042] Among them Figure 3 and Figure 4As shown, the circumferential cross-section of the drum 102 is set to be trapezoidal, so that the parts and some steel shots can be accumulated inside the drum 102, increasing the tumbling space of the parts. A number of through holes 107 for the steel shots to pass through are evenly distributed on the surface of the drum 102. The size of the through holes 107 is larger than the maximum size of the steel shots and smaller than the minimum size of the parts, so that the steel shots can smoothly pass through the through holes 107 and fall to the outside of the drum 102 for easy recovery.

[0043] Among them Figure 1 As shown, a controller 108 is fixedly installed on one side of the box 101. The controller 108 is electrically connected to the first motor 302 and the second motor 309. The controller 108 is connected to the electrical components of the device to facilitate the transmission of instructions and control of the operation of the device.

A gear 110 is meshed with the lower end of the gear ring 109. The rotating shaft of the gear 110 is fixedly connected to the second synchronous wheel. The second synchronous wheel is connected to the first synchronous wheel through a synchronous belt 111. Under the transmission cooperation of the first motor 302 and the synchronous belt 111, when the reciprocating screw rod 301 rotates, the drum 102 is also in a rotating state, so that the parts can be turned over inside the drum 102, so as to realize the deburring operation of the steel shot on different surfaces of the parts, increase the contact area between the steel shot and the parts, and avoid the situation that the removal operation is not comprehensive.

[0045] Among them Figure 3 and Figure 4 As shown, a receiving hopper 112 is slidably provided at the bottom of the box body 101, and the receiving hopper 112 is connected to the box body 101 by a plurality of bolts, so as to facilitate timely cleaning.

[0046] When in use, first place a number of parts into the drum 102 through the inlet and outlet 105, start the first motor 302 to drive the reciprocating screw 301 to rotate, so that the shot peening machine 103 can move back and forth, and realize the swing effect with the cooperation of the swing assembly. At this time, the synchronous belt 111 and the gear 110 are also in a transmission state, driving the drum 102 to roll, and the steel shot ejected by the shot peening machine 103 hits the surface of the parts to achieve the burr removal operation on the surface of the parts, and the burr slag and part of the steel shot fall onto the surface of the sieve plate 402 through the through hole 107. The cam 403 drives the screen plate 402 to move up and down, thereby realizing the separation operation of burrs and steel shots. The steel shots remaining on the surface of the screen plate 402 enter the collection box 201 through the separation port 106 and roll to the bottom of the screw conveyor 203. The screw conveyor 203 and the conveying pipe 204 convey a number of steel shots back to the shot blasting machine 103 to wait for another spraying. The burrs and slag after screening fall into the receiving hopper 112. After the deburring operation is completed, the receiving hopper 112 is slid out to realize the collection operation of the slag.
