Frequent manual adjustment greatly increases the milling time and reduces the milling efficiency. In addition, due to the error of manual operation, it is difficult to ensure the accuracy of each fixation, which may lead to a decrease in milling accuracy.

[0004] The present invention aims to solve the problems existing in the above patents. To this end, a rack surface milling device is proposed, which can automatically transport and align the rack blank to complete the milling process, thereby improving the milling accuracy and efficiency.

[0033] See also Figure 6-Figure 9 As shown, the cleaning component includes an air guide shell 12, a porous tube 121, a driving motor 122, a suction component, a semicircular frame 124 and a screw conveying shaft 125. The top of the movable seat 3 is symmetrically fixed with the air guide shell 12, and the left and right sides of the electric clamps 6 are fixed with the semicircular frame 124 on the sides away from each other. The semicircular frame 124 is located directly below the air guide shell 12, and the porous tube 121 is fixedly connected between the front and rear sides of the semicircular frame 124. The front side of the porous tube 121 has no holes in the circumferential direction and is outside the semicircular frame 124. The discharge end of the porous tube 121 is at the front side, and the left and right sides of the porous tube 121 are respectively in contact with the left and right sides inside the semicircular frame 124. The front and rear sides of the porous tube 121 are rotatably connected with the screw conveying shaft 125. When the screw conveying shaft 125 rotates, the screw conveying The shaft 125 can drive the debris to move forward and be discharged. A driving motor 122 is installed on the outer front side of the porous tube 121. The output shaft end of the driving motor 122 is fixedly connected to the front end of the spiral conveying shaft 125. A suction component is arranged between the semicircular frame 124 and the movable seat 3. When the suction component is in operation, the suction component can realize vacuuming in the semicircular frame 124 so that the semicircular frame 124 is in a negative pressure state; the suction component includes a suction pipe 123 and a bellows 1231. The left and right sides of the semicircular frames 124 that are away from each other are both connected with the bellows 1231, and the bellows 1231 corresponds to the porous tube 121. The suction pipe 123 is connected between the left and right sides of the movable seat 3, and the suction end of the suction pipe 123 is connected to the ends of the bellows 1231 on the left and right sides.

[0034] Initially, the movable seat 3 is at the front side, the porous tube 121 is externally connected to the collecting container and the suction tube 123 is externally connected to the vacuum pump. First, the rack blank is placed on the front support plate 4 from the front side, and the rack blank is pushed to move backward through the front n-type plate 11 and placed on the conveying roller 7. When the rack blank moves backward to the milling position, the rack blank is stopped from moving backward. The rack blank is located under the electric cutting machine 5. The electric clamps 6 on the left and right sides are started to move inward to clamp the rack blank, and the electric clamps 6 are closed. Then the electric cutting machine 5 is started to move downward to mill the rack blank, so that the rack blank is milled with tooth grooves. At the same time, the left and right movement of the dual-axis moving machine 2 can drive the rack blank to move left and right through the movable seat 3 and the electric clamp 6. The left and right movement of the rack blank makes the tooth grooves completely After the milling is completed, the electric cutting machine 5 moves upward for a distance, and the electric cutting machine 5 is out of contact with the rack blank. At this time, the dual-axis moving machine 2 drives the movable seat 3 to move backward, and the movable seat 3 moves backward and drives the rack blank to move backward through the electric clamp 6, so that the next milling position of the rack blank is directly below the electric cutting machine 5, and the dual-axis moving machine 2 stops driving the movable seat 3 to move backward, and the rack blank stops moving backward. Then the electric cutting machine 5 continues to move downward to mill the rack blank. This process is repeated, and the rack blank can be continuously milled. At the same time, the external vacuum pump is started, and the vacuum pump makes the semicircular frame 124 in a negative pressure state through the suction pipe 123 and the bellows 1231, and the semicircular frame 124 makes the porous tube 121 and the air guide shell 12 in a negative pressure state. In the negative pressure state, the air guide shell 12 draws the debris generated during the cutting process into the porous tube 121 and is adsorbed on the inner wall. The drive motor 122 is started to drive the screw conveying shaft 125 to rotate. The screw conveying shaft 125 rotates and contacts the debris on the inner wall of the porous tube 121. The rotation of the screw conveying shaft 125 drives the debris to move forward for transportation. When the debris is transported to the front side of the porous tube 121, the debris stops being adsorbed by the porous tube 121, and the debris is discharged from the porous tube 121 into an external collection container. This is repeated, and the debris generated during the cutting process can be continuously removed and collected, which can prevent the debris from being ejected to the surroundings and affecting the working environment, thereby ensuring a good working environment. When the part of the rack blank that contacts the conveying roller 7 is milled, the movable seat 3 is close to the rear support plate. 4. Start the electric clamps 6 on the left and right sides to move outward and reset to loosen the rack blank. At this time, the servo motor 10 starts to drive the worm 9 to rotate forward, and the worm 9 rotates forward to drive the worm wheel 8 to rotate forward. The worm wheel 8 rotates forward to drive the conveying roller 7 to rotate forward. The conveying roller 7 rotates forward to drive the rack blank to move backward. The rack blank moves backward and is on the rear support plate 4. The rear support plate 4 supports the rack blank. When the position of the next section of the rack blank that needs to be milled moves to the conveying roller 7, turn off the servo motor 10, and the worm 9 stops driving the conveying roller 7 to rotate forward through the worm wheel 8. At this time, the electric lead screw 116 rotates forward to drive the return plate 115 to move downward, and the return plate 115 moves downward to drive the guide rod 113 to move downward. The guide rod 113 moves downward and drives the n-type plate 11 to move downward through the connecting spring 114.The front n-type plate 11 moves downward, driving the pressure roller 111 to move downward and contact the rack blank. The pressure roller 111 limits the rack blank. At the same time, the rear n-type plate 11 moves downward, driving the reference block 112 to move downward. The reference block 112 moves downward and contacts the tooth grooves milled on the rack blank. The reference block 112 performs tool alignment on the rack blank, so that the rack blank is in a precise position for subsequent milling processing. Due to the action of the connecting spring 114, the reference block 112 can be more closely contacted with the rack blank for tool alignment. Then the electric screw rod 116 reverses and drives the return plate 115 to move upward and reset. The return plate 115 drives the n-type plate 11 to move upward and reset through the guide rod 113 and the connecting spring 114. The reset of the n-type plate 11 drives the pressure roller 111 and the reference block 112 to move upward and reset. Then the electric clamp 6 clamps and fixes the rack blank after tool alignment. According to the above operation, the rack blank can continue to be milled until the milling of all the tooth grooves of the rack blank is completed. When all the tooth grooves of the rack blank are milled, the external vacuum pump is turned off, the air guide shell 12 and the porous tube 121 stop being in a negative pressure state, and then the drive motor 122 is turned off, the spiral conveying shaft 125 stops rotating, and the rack blank can be removed from the support plate 4 for subsequent processing. In this way, through the function of the conveying roller 7, the rack blank can be automatically conveyed and the tool is aligned to complete the milling process, so that the position of the rack blank can be adjusted without manual intervention, thereby improving the milling accuracy and efficiency.

[0035] See also Fig.10 and Fig.11 As shown, the rack surface milling device also includes a positioning component installed on the movable seat 3, the positioning component includes a guide frame 13, a guide rod 131, a positioning plate 132 and an adjustment component, the right side of the rear side of the movable seat 3 is embedded with a guide rod 131 in a sliding connection, the rear end of the guide rod 131 is fixedly connected to the guide frame 13, and the inner side of the guide frame 13 is slidably connected with a positioning plate 132. When the rack embryo moves and contacts the positioning plate 132, the positioning plate 132 can realize the positioning of the rack embryo. An adjustment component is arranged between the movable seat 3 and the guide frame 13. When the adjustment component is in operation, the adjustment component can realize the adjustment of the position of the movable frame; the adjustment component It includes an adjusting screw 133, an adjusting screw 134 and a stepper motor 135. The adjusting screw 134 is vertically rotatably connected to the rear side of the guide frame 13. The adjusting screw 134 is threadedly connected to the rear side of the positioning plate 132. When the adjusting screw 134 rotates, the adjusting screw 134 can drive the positioning plate 132 to move downward and retract. A stepper motor 135 is installed on the rear side of the bottom of the guide frame 13. The output shaft end of the stepper motor 135 is fixedly connected to the bottom end of the adjusting screw 134. The adjusting screw 133 is rotatably connected to the left side of the guide frame 13. When the adjusting screw 133 rotates, the adjusting screw 133 can drive the guide frame 13 to move for position adjustment.

[0036] First, the operator twists the adjusting screw 133 to rotate forward, and the adjusting screw 133 rotates forward to drive the guide frame 13 to move backward, and the guide rod 131 guides the guide frame 13. The guide frame 13 moves backward to drive the positioning plate 132 to move backward. When the positioning plate 132 moves backward to the position where the rack blank is placed, the operator stops twisting the adjusting screw 133, and the guide frame 13 stops driving the positioning plate 132 to move backward. Then, the rack blank can be placed and pushed to move backward onto the conveying roller 7. When the rack blank moves backward and contacts the positioning plate 132, the rack blank also moves to the milling position. At this time, the stepper motor 135 is started to drive the adjusting screw 134 to rotate forward, and the adjusting screw 134 rotates forward to drive the positioning plate 132 to move downward. The positioning plate 132 moves downward and loses contact with the rack blank. The stepper motor 135 is turned off, and the rack blank can be milled. When the milling of a rack blank is completed, the stepper motor 135 is started to reverse and drive the adjusting screw 134 to reverse, and the adjusting screw 134 reverses and drives the positioning plate 132 to move upward and reset, and the positioning plate 132 continues to position the next rack blank, so that the position of the rack blank is consistent each time without affecting the accuracy of milling. When all rack blanks are milled, the adjusting screw 133 is twisted to reverse and drive the guide frame 13 to move forward and reset, and the guide frame 13 resets and drives the positioning plate 132 to move forward and reset. In this way, the inconsistent position of the rack blank each time can be prevented from affecting the accuracy of milling, thereby further improving the accuracy of rack blank milling.

[0037] See also Figure 1 and Fig.12 As shown, the rack surface milling equipment also includes an inclined plate 14, a drain pipe 15 and a water spray pipe 16. The water spray pipe 16 is fixedly connected to the electric cutting machine 5, and the water spray pipe 16 can spray the cutting fluid on the rack blank and the electric cutting machine 5. The bottom of the semicircular frame 124 is fixedly connected to the inclined plate 14, and the inclined plate 14 can guide water. The lower front part of the semicircular frame 124 is connected to the drain pipe 15, and the drain pipe 15 passes through the porous pipe 121. The drainage end of the drain pipe 15 is located in the porous pipe 121.

[0038] Initially, the water spray pipe 16 is externally connected to a machine equipped with cutting fluid. When the electric cutting machine 5 performs milling processing on the rack blank, the cutting fluid is discharged into the water spray pipe 16. The water spray pipe 16 sprays the cutting fluid on the electric cutting machine 5 and the rack blank. The electric cutting machine 5 performs milling processing on the rack blank through the cutting fluid, and the used cutting fluid flows into the porous pipe 121 through the electric clamp 6. The cutting fluid passes through the porous pipe 121 and falls downward onto the inclined plate 14. The cutting fluid on the inclined plate 14 is discharged into the drain pipe 15, and the drain pipe 15 discharges the cutting fluid into the collection container. When the milling processing of the rack blank is completed, the cutting fluid is stopped from being discharged into the water spray pipe 16. In this way, the electric cutting machine 5 can be cooled and lubricated, so as to better mill the rack blank.
