[0039] The angle mechanism includes a space cam 121, and the four space cams 121 are respectively connected to the middle parts of the four rotating frames 4 by bolts. The space cams 121 are provided with spiral grooves. The middle part of the support column 2 is slidably connected with a lifting ring 122, and a second adjusting screw 123 is rotatably connected in the support column 2. The second adjusting screw 123 is threadedly connected to the lifting ring 122. Four guide rods 124 are evenly connected in the center frame 3 by bolts, and a synchronous ring 125 is slidably connected between the four guide rods 124. Four guide columns are provided on the synchronous ring 125. The guide columns of the synchronous ring 125 drive the rotating frame 4 to swing by squeezing the spiral grooves of the space cams 121. The synchronous ring 125 is rotatably connected to the lifting ring 122, and the four guide columns of the synchronous ring 125 are respectively slidably connected to the spiral grooves of the four space cams 121.

[0040] First, the operator rotates the rotating arm 104 according to the size of the forging 1041 that needs to be polished. When one of the rotating arms 104 is rotated, the rotating arm 104 will drive the other rotating arm 104 to rotate by the same angle through the two half-side gears 105. When the spacing between the rod-like structures of the two rotating arms 104 is the same as the spacing between the pin holes at both ends of the forging 1041, the pin holes of the forging 1041 are then aligned with the rod-like structures of the two rotating arms 104 and the forging 1041 is placed on the two rotating arms 104. In this way, the two rotating arms 104 are kept symmetrical through the two half-side gears 105, so that the centers of the forgings 1041 of different sizes are always located On the axis of the subsequent moving direction of the forging 1041, the operator then controls the telescopic rod of the hydraulic rod 106 to retract in the direction close to the forging 1041. The retraction of the telescopic rod of the hydraulic rod 106 will pull the limit rod 107 in the direction close to the forging 1041 through the tension spring 108, and then the limit rod 107 will press against the forging 1041 through the contact pad 109, thereby avoiding crushing the forging 1041 through the contact pad 109. The telescopic rod of the hydraulic rod 106 continues to retract, the tension spring 108 is stretched, and the tension of the tension spring 108 continuously applies pressure to the forging 1041 through the limit rod 107. In this way, the rotating arm 100 of the adjustable spacing can be After supporting the forging 1041, the limiting rod 107 which automatically adapts to the distance is used to press against the forging 1041, so that the forgings 1041 of different sizes can be fixed, so that the forging 1041 is more stable in the subsequent polishing process, thereby enhancing the polishing effect of the processing device on the surface of the forging 1041; then the operator starts the motor 7, the output shaft of the motor 7 rotates to drive the first gear 8 to rotate, the first gear 8 rotates to drive the center frame 3 to rotate through the second gear 9, the center frame 3 rotates to drive the four rotating frames 4 to rotate, so that the four rotating frames 4 respectively drive the four polishing rollers 6 to rotate through the four rotating shafts 5, and the center frame 3 drives the four rotating frames 4 to rotate At the same time, the fourth gears 112 on the four rotating frames 4 will respectively drive the first transmission wheels 113 to rotate through the third gears 111, and the rotation of the first transmission wheels 113 will respectively drive the four second transmission wheels 115 to rotate through the four transmission belts 114, and the rotation of the four second transmission wheels 115 will respectively drive the four polishing rollers 6 to rotate through the four rotating shafts 5. In this way, the center frame 3 drives the polishing roller 6 to rotate while the second transmission wheels 115 drive the polishing roller 6 to rotate, thereby strengthening the friction of the polishing roller 6 on the forging 1041, so that the polishing roller 6 can better polish the forging 1041, thereby improving the polishing efficiency of the processing device on the surface of the forging 1041;When the inner diameter of the forging 1041 is larger, the operator rotates the second adjusting screw 123, and the rotation of the second adjusting screw 123 will drive the synchronous ring 125 to move downward through the lifting ring 122, and the downward movement of the synchronous ring 125 will drive the four rotating frames 4 to rotate outward and expand through the four space cams 121, so that the polishing radius of the four polishing rollers 6 is increased. When the inner diameter of the forging 1041 is smaller, the operator rotates the second adjusting screw 123 in the opposite direction, and the reverse rotation of the second adjusting screw 123 will drive the synchronous ring 125 to move upward through the lifting ring 122, and the upward movement of the synchronous ring 125 will drive the four rotating frames 4 to rotate inward and shrink through the four space cams 121, so that the polishing radius of the four polishing rollers 6 is reduced. In this way, the expansion angle of the rotating arm 104 can be adjusted according to the size of the forging 1041 through the second adjusting screw 123, and then the polishing radius of the polishing roller 6 can be adjusted, so that the polishing The polishing roller 6 can polish the surface of the forgings 1041 of different sizes, thereby further enhancing the polishing effect of the processing device on the surface of the forgings 1041; then the operator drives the sliding seat 102 to move toward the direction close to the frame 1 by rotating the first adjusting screw 103, and the movement of the sliding seat 102 will drive the forging 1041 to approach the polishing roller 6 through the two rotating arms 104, and then polish the forging 1041. After the polishing is completed, the operator turns off the motor 7, and then reversely rotates the first adjusting screw 103 to reset the sliding seat 102. The reset of the sliding seat 102 will drive the forging 1041 to reset through the rotating arm 104, and then the operator controls the extension and reset of the telescopic rod of the hydraulic rod 106, and the tension spring 108 is reset. After the extension of the telescopic rod of the hydraulic rod 106, it will push the limit rod 107 to reset, so that the limit rod 107 no longer presses against the forging 1041, and then the operator can remove the forging 1041. ;

[0041] Embodiment 2: Based on embodiment 1, Figure 1-Figure 13As shown, it also includes a center mechanism, which is arranged on the limit rod 107, and the center mechanism is used to position the forging 1041. The center mechanism includes a support rod 131, and the support rod 131 is connected to the end of the limit rod 107 close to the contact pad 109 by bolts. The upper and lower ends of the support rod 131 are slidably connected with positioning blocks 132, and the positioning blocks 132 are used to position the forging 1041. The two positioning blocks 132 are symmetrically arranged, and the sides of the two positioning blocks 132 close to each other are respectively connected to the support rod 131 with pressure springs 133. The two pressure springs 133 are symmetrically arranged, and the two sides of the two positioning blocks 132 are respectively rotatably connected with connecting rods 134, and the two connecting rods 134 on the same side are a group. There are two groups of connecting rods 134, and the two connecting rods 134 in the same group are symmetrically arranged. The two groups of connecting rods 134 are symmetrically arranged, and a sliding rod 135 is rotatably connected between the two connecting rods 134 in each group. The two sliding rods 135 are symmetrically arranged, and the sliding rod 135 drives the positioning block 132 to move by pulling the connecting rod 134. The end of the limit rod 107 away from the frame 1 is rotatably connected to a support shaft 136, and both ends of the support shaft 136 are connected to a winding wheel 137 through a key groove. The top of the telescopic rod of the hydraulic rod 106 is connected to a connecting block 138 by bolts, and two steel wire ropes 139 are connected to the side of the connecting block 138 close to the winding wheel 137, and the two steel wire ropes 139 are respectively passed around the two winding wheels 137 and connected to the two sliding rods 135.

[0042] After the telescopic rod of the hydraulic rod 106 drives the limit rod 107 to press against the forging 1041 through the tension spring 108, the telescopic rod of the hydraulic rod 106 continues to move in the direction close to the forging 1041. The telescopic rod of the hydraulic rod 106 continues to move, which will pull the wire rope 139 through the connecting block 138, so that the wire rope 139 will pull the sliding rod 135 through the winding wheel 137 to move away from the forging 1041. The movement of the sliding rod 135 will pull the two positioning blocks 132 in the direction of approaching each other through the connecting rod 134, and the pressure spring 133 will be compressed. The two positioning blocks 132 approach each other and contact the forging 1041 from the upper and lower sides, so that the forging 1041 moves. To the middle position, in this way, after clamping the forging 1041, the forging 1041 is moved to the middle position through the two positioning blocks 132, and then the height of the groove of the forging 1041 is positioned, so that the polishing ring of the polishing roller 6 can polish the groove of the forging 1041 more accurately, thereby further enhancing the polishing effect of the processing device on the surface of the forging 1041; after polishing is completed, the telescopic rod of the hydraulic rod 106 is reset and no longer pulls the wire rope 139 through the connecting block 138. The pressure spring 133 is reset to reset the two positioning blocks 132. The reset of the positioning block 132 will pull the sliding rod 135 to reset through the connecting rod 134, so that the wire rope 139 returns to its initial state.

[0043] Embodiment 3: Based on embodiment 2, Figure 1-Figure 14 As shown, a shielding mechanism is also included, and the shielding mechanism is arranged on the frame 1. The shielding mechanism is used to shield flying debris. The shielding mechanism includes a shielding cover 141, and the shielding cover 141 is connected to the frame 1 by bolts. The shielding cover 141 is used to shield flying debris when polishing the forging 1041. The top of the support rod 131 is connected to a support seat 142 by bolts, and a shielding cover 143 is rotatably connected to the support seat 142. The shielding cover 143 is used to shield flying debris when polishing the forging 1041. The positioning block 132 located at a high position is connected to a contact frame 144 by bolts, and the contact frame 144 is in contact with the shielding cover 143.

[0044] The shielding hood 141 and the shielding cover 143 are made of acrylic material, and the shielding hood 141 and the shielding cover 143 made of acrylic material are used to observe the polishing condition while shielding.

[0045] It also includes a sliding frame 15, which is slidably connected to the shielding cover 141, and has two through holes in it. A handle 16 is connected between the two ends of the sliding frame 15 away from the support column 2, and a shunt pipe 17 is connected between the two ends of the sliding frame 15 close to the handle 16. The shunt pipe 17 is used to divert the polishing agent, and a brush strip 18 is connected to the end of the sliding frame 15 away from the shunt pipe 17. The brush strip 18 is used to apply the polishing agent to the polishing roller 6.

[0046] At first, the contact frame 144 is against the shielding cover 143, so that the shielding cover 143 is in an open state. When the positioning block 132 moves downward to position the forging 1041, the contact frame 144 will be driven to move downward, so that the contact frame 144 no longer resists the shielding cover 143. The shielding cover 143 is supported by the end of the support seat 142 close to the forging 1041 after rotating downward by 90 degrees through the center of gravity. Then, when the operator moves the sliding seat 102 to drive the forging 1041 to polish, the shielding cover 143 will move in the direction close to the shielding cover 141 and then align with the shielding cover 141. In this way, when the forging 1041 is polished, it is shielded by the acrylic shielding cover 141 and the shielding cover 143, so that the debris can be blocked and observed at the same time, so that the polishing process of the forging 1041 can be targetedly adjusted to the polishing condition, thereby further enhancing the polishing effect of the processing device on the surface of the forging 1041; during polishing, the operator The operator connects the polishing agent feeding pump to the shunt pipe 17. After the operator starts the feeding pump, the feeding pump will pump the polishing agent into the through hole of the sliding frame 15 through the shunt pipe 17. Then the polishing agent will adhere to the brush strip 18 through the through hole of the sliding frame 15. Then the operator moves the position of the sliding frame 15 through the handle 16, so that the center frame 3 drives the polishing roller 6 to rotate and contact with the brush strip 18. In this way, the center frame 3 drives the polishing roller 6 to rotate and contact with the brush strip 18 with the polishing agent attached, and then the polishing agent is applied to the polishing roller 6, so that the polishing roller 6 can better polish the forging 1041 with the polishing agent, thereby further enhancing the polishing effect of the processing device on the surface of the forging 1041; after the polishing agent is applied, the operator turns off the feeding pump. After polishing is completed, the positioning block 132 is reset to drive the contact frame 144 to reset. The reset of the contact frame 144 will squeeze the bottom of the shielding cover 143, so that the shielding cover 143 rotates upward and opens to return to the initial state.

[0047] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
