[0003] The front end cover is usually of an integral structure. There are multiple assembly holes provided on the front end cover, and lifting lugs are also provided on the circumferential side of the front end cover. In the related art, a drilling device is usually used to drill the end cover casting to process the assembly holes.

[0004] Chinese Patent with the authorization announcement number CN118218642B discloses an ultrasonic vibration drilling machine for punching the condenser end cover plate, which includes: an ultrasonic generator and a drilling machine body. The ultrasonic generator is used to provide ultrasonic vibration to the drill bit on the drilling machine body. The drilling machine body includes a workbench, a column, a frame, a feed seat, a feed screw, a feed motor, and an ultrasonic drill handle. One side above the workbench is fixedly installed with a column, the top of the column is fixedly provided with a frame, a feed seat is arranged between the frame and the workbench, an ultrasonic drill handle is installed at one end of the feed seat, and a chip shielding mechanism is arranged above the workbench.

[0005] The above patent can shield the chips generated by drilling through the shielding cover, preventing the chips generated during drilling from splashing.

[0006] However, the above patent requires manual fixation, and the disassembly and assembly efficiency is low. Summary of the Invention

[0007] The present invention provides a drilling processing device and processing method for the front end cover of an aluminum motor, aiming to solve the problems of manual positioning and low drilling efficiency in the related art.

[0008] The drilling processing device for the front end cover of the aluminum motor of the present invention includes: a frame, a workbench, and a positioning component; A lifting mechanism is provided on the frame, and a drilling mechanism is provided on the lifting mechanism; The workbench is arranged on the frame. An installation seat is provided on the workbench. A plurality of shielding plates are rotatably matched with the installation seat. The shielding plates are connected to the installation seat through a first torsion spring. The plurality of shielding plates are circumferentially spaced apart along the installation seat; The positioning component includes a positioning groove and a positioning plate. A plurality of the positioning grooves are circumferentially spaced apart along the mounting base. A support rod is provided in the positioning groove. The lifting lug of the end cover can extend into the positioning groove. Each of the shielding plates is provided with one of the positioning plates. The positioning plate is an arc-shaped plate and can be attached to the side wall of the end cover. A shifting plate is further provided on the mounting base. The shifting plate is rotationally matched with the mounting base through a second torsion spring. A pushing plate is hinged to the shifting plate, and the pushing plate can abut against the shielding plate. A push rod is provided on the lifting mechanism, and the push rod can push the shifting plate to rotate.

[0009] Beneficial effects: Place the lifting lug of the front end cover in the positioning groove, and support the front end cover through the support plate. When the lifting mechanism moves downward, the push rod pushes the shifting plate to rotate, and the shifting plate drives the pushing plate to move inward, causing the shielding plate to contract. During the contraction process of the shielding plate, the positioning plate is driven to move inward. A plurality of positioning plates approach the front end cover from different directions, and push the front end cover to move to be coaxially distributed with the mounting base, and clamp the front end cover, realizing automatic positioning of the front end cover.

[0010] Preferably, clamping plates are rotationally matched on both sides of the positioning groove. Both of the clamping plates are connected to the positioning groove through a first elastic member, and the two clamping plates are symmetrically distributed. A stopper is provided on the outer side of the clamping plate, and the stopper can abut against the shielding plate. The clamping plate can abut against the side wall of the lifting lug of the end cover.

[0011] The effect is that the front end cover is clamped by the clamping plates, thereby preventing the front end cover from rotating during the drilling process. The two clamping plates are elastically connected to the positioning groove, so as to be able to adapt to lifting lugs of different sizes.

[0012] Preferably, the positioning plate is detachably connected to the shielding plate through a bolt.

[0013] The effect is that when processing front end covers of different sizes, the corresponding positioning plate can be replaced to make the radian of the positioning plate consistent with the radian of the front end cover to be processed.

[0014] Preferably, the positioning groove includes a first positioning groove and a plurality of second positioning grooves. The support rod includes a first support rod and a second support rod. The first support rod is fixedly connected in the first positioning groove. The second support rod is slidably matched in the second positioning groove. A connecting rod is provided on the second support rod. A limiting elastic ball is elastically connected to the connecting rod. The limiting elastic ball can be received into the connecting rod, and the limiting elastic ball can abut against the shielding plate.

[0015] The effect is that during the positioning process, the shielding plate moves inwards, and the shielding plate can cross over the limit ball and move to the inner side of the limit ball. After the processing is completed, the shielding plate resets and opens outwards. During this process, the shielding plate abuts against the limit ball and pulls the connecting rod to move outwards, causing the second support rod to disengage from the front end cover. At this time, only the first support rod abuts against the bottom end of the front end cover, and the front end cover can tilt downwards. During the tilting process of the front end cover, the processing debris scattered on its upper surface can slide off the front end cover.

[0016] Preferably, a blanking port is provided on the workbench, the blanking port is located below the mounting seat, a discharge hopper is provided in the frame, the discharge hopper is located below the blanking port, and the discharge hopper is inclinedly distributed.

[0018] Preferably, a plurality of sieve holes are provided on the discharge hopper, and the plurality of sieve holes are spaced apart on the discharge hopper.

[0019] Preferably, a collection box is provided below the discharge hopper.

[0020] An aluminum motor front end cover processing method, applied to the above-mentioned aluminum motor front end cover drilling processing device, includes the following steps: The first step is loading. Place the lifting lug of the front end cover on the support rod of the positioning groove. The second step is positioning. The lifting mechanism moves downwards, causing the push rod to gradually approach the dial plate and push the dial plate to rotate. The dial plate drives the push plate to move inwards. The push plate gradually approaches the shielding plate and pushes the shielding plate to rotate inwards and fold up. The positioning plate moves synchronously with the shielding plate, and a plurality of positioning plates move inwards synchronously, thereby pushing the front end cover to be coaxially distributed with the mounting seat and clamping the front end cover. The third step is drilling. Drill the front end cover through the drilling mechanism. The fourth step is blanking. The lifting mechanism moves upwards, the dial plate and the shielding plate reset, the positioning plate disengages from the front end cover, the pull rope pulls the support rod to move outwards, causing it to disengage from the lifting lug of the front end cover, and the front end cover can fall on the discharge hopper.

[0021] Place the lifting lug of the front end cover in the positioning groove, support the front end cover through the support plate. When the lifting mechanism moves downwards, the push rod pushes the dial plate to rotate. The dial plate drives the push plate to move inwards, causing the shielding plate to contract. During the contraction process of the shielding plate, it drives the positioning plate to move inwards. A plurality of positioning plates approach the front end cover from different directions, and push the front end cover to move to be coaxially distributed with the mounting seat and clamp the front end cover, realizing automatic positioning of the front end cover.

[0022] Adopting the above technical solution, the beneficial effect of the present invention is as follows: According to the aluminum motor front end cover drilling and processing device and processing method of the present invention, the lug of the front end cover is placed in the positioning groove, and the front end cover is supported by the support plate. When the lifting mechanism moves downward, the push rod pushes the dial plate to rotate, and the dial plate drives the push plate to move inward, so that the shielding plate contracts. During the contraction process of the shielding plate, the positioning plate is driven to move inward. Multiple positioning plates approach the front end cover from different directions, and push the front end cover to move to be coaxially distributed with the mounting seat, and clamp the front end cover, realizing automatic positioning of the front end cover and improving the processing efficiency.

[0036] As Figures 2 to 6As shown in the figure, the positioning component includes a positioning groove and a positioning plate 12. The positioning groove includes a first positioning groove 101 and a plurality of second positioning grooves 102. The first positioning groove 101 and the plurality of second positioning grooves 102 are evenly spaced along the circumferential direction of the mounting base 5 on the mounting base 5. Two symmetrically distributed first support rods 111 are provided in the first positioning groove 101. The first support rods 111 are fixedly connected in the first positioning groove 101. Two symmetrically distributed second support rods 112 are provided in each second positioning groove 102. The second support rods 112 are slidably matched with the second positioning grooves 102. The second support rods 112 are elastically connected to the second positioning grooves 102 through second elastic members 1121. The second elastic members 1121 are springs. A connecting rod 1122 is also fixedly connected to the second support rods 112. A limiting ball 1123 is provided on the connecting rod 1122. The limiting ball 1123 is elastically connected to the connecting rod 1122. The limiting ball 1123 can be received into the connecting rod 1122. The limiting ball 1123 can abut against the corresponding shielding plate 6. A positioning plate 12 is provided on each shielding plate 6. The outer wall of the positioning plate 12 is detachably connected to the shielding plate 6 through bolts. The positioning plate 12 is an arc-shaped plate, and its radian is the same as the radian of the side wall of the front end cover.

[0037] As Figure 4 , Figure 5 and Figure 7 shown in the figure, clamping plates 13 are rotatably matched on both sides of the first positioning groove 101 and the second positioning groove 102. The clamping plates 13 on both sides of each positioning groove are symmetrically distributed. Each clamping plate 13 is elastically connected to the first positioning groove 101 or the second positioning groove 102 through a first elastic member 131. The first elastic member 131 is a spring. A stop block 132 is also provided on the outer side of the clamping plate 13. The stop block 132 can abut against the shielding plate 6.

[0038] As Figure 1 and Figure 8 shown in the figure, a discharge hopper 14 is also provided in the frame 1. The discharge hopper 14 is located below the blanking port. The discharge hopper 14 is inclined. Its bottom end extends outside the frame 1. Sieve holes 141 are provided on the discharge hopper 14. The plurality of sieve holes 141 are spaced on the discharge hopper 14. A collection box 15 is also provided below the discharge hopper 14.

[0039] A processing method for the front end cover of an aluminum motor is applied to the above-mentioned drilling processing device for the front end cover of an aluminum motor. Its steps include: In the first step, loading. Place the front end cover on the mounting base 5. At this time, the lugs on the circumferential side of the front end cover are all placed in the first positioning groove 101 or the second positioning groove 102, and the corresponding lugs are supported by the first support rods 111 and the second support rods 112 to prevent the front end cover from falling.

[0040] In the second step, positioning: The first driving member 22 drives the lifting seat 21 to move downward. The push rod 9 moves downward synchronously with the lifting seat 21. The push rod 9 gradually approaches the dial plate 7 and abuts against it. While moving downward, the push rod 9 pushes the dial plate 7 to rotate. The rotation of the dial plate 7 drives the push plate 8 to move inward. The push plate 8 pushes the upper end of the shielding plate 6 to move inward until the shielding plate 6 rotates to a vertical state. During the rotation of the shielding plate 6, the positioning plate 12 gradually contacts the front end cover and pushes the front end cover to move until multiple positioning plates 12 all abut against the front end cover. At this time, the positioning plate 12 can clamp the front end cover, and the front end cover and the mounting seat 5 are coaxially distributed. At the same time, during the rotation of the shielding plate 6, the shielding plate 6 also gradually approaches the stopper 132 and pushes the two stoppers 132 in the same positioning groove to approach each other, so that the two clamping plates 13 approach each other and clamp the lug of the front end cover to fix the front end cover. During the rotation of the shielding plate 6, it can also move past the limit ball 1123 and move to the inner side of the limit ball 1123.

[0041] In the third step, drilling: The front end cover is drilled through the drilling mechanism 3.

[0042] In the fourth step, blanking: The first driving member 22 drives the lifting seat 21 to move upward, so that the push rod 9 is disengaged from the dial plate 7. Under the action of the second torsion spring, the dial plate 7 resets. The push plate 8 releases the limit on the shielding plate 6. Under the action of the first torsion spring, the shielding plate 6 resets, and the top end of the shielding plate 6 moves outward. The shielding plate 6 abuts against the limit ball 1123 and pulls the connecting rod 1122 and the second support rod 112 to move outward, so that the second support rod 112 gradually disengages from the lug of the front end cover. Since only the first support rod 111 contacts the front end cover, the drilled front end cover tilts and falls from the blanking port. After the front end cover tilts, the processed debris scattered on its upper surface will slide off the front end cover. The front end cover finally lands on the discharge hopper 14 and is discharged from the frame 1 along the discharge hopper 14. The processed debris will also land on the discharge hopper 14 and enter the collection box 15 through the sieve holes 141.
