[0001] The present invention relates to the technical field of drilling equipment, and particularly relates to a drilling processing device and method for the front end cover of an aluminum motor. Background Art

[0002] The front end cover of an aluminum motor is an important component of the motor, and its main functions include: protecting the interior of the motor. The front end cover of the aluminum motor can protect the components inside the motor from the external environment, such as dust, moisture, corrosion, and physical damage, thereby extending the service life of the motor; supporting and fixing. The front end cover provides support and fixation for the rotor and bearings of the motor, ensuring the stability and reliability of the rotor and bearings during operation.

[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 drilling 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 rod, 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] By setting the shielding cover, the above patent can shield the chips generated by drilling through the shielding cover to prevent the chips from splashing during drilling.

[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 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 assembly;

[0009] A lifting mechanism is provided on the frame, and a drilling mechanism is provided on the lifting mechanism;

[0010] The workbench is arranged on the frame. An installation seat is provided on the workbench. A plurality of shielding plates are rotatably fitted to the installation seat. The shielding plates are connected to the installation seat through a first torsion spring. The plurality of shielding plates are distributed at intervals along the circumferential direction of the installation seat.

[0011] The positioning assembly includes a positioning groove and a positioning plate. The plurality of positioning grooves are distributed at intervals along the circumferential direction of the installation seat. A support rod is provided in the positioning groove. The lifting lug of the end cover can extend into the positioning groove. A positioning plate is provided on each shielding plate. The positioning plate is an arc-shaped plate. The positioning plate can be attached to the side wall of the end cover. A dial is further provided on the installation seat. The dial is rotatably fitted to the installation seat through a second torsion spring. A push plate is hinged to the dial. The push plate can abut against the shielding plate. A push rod is provided on the lifting mechanism. The push rod can push the dial to rotate.

[0012] 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 dial to rotate. The dial drives the push 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. The plurality of positioning plates approach the front end cover from different directions and push the front end cover to move to a coaxial distribution with the installation seat and clamp the front end cover, realizing automatic positioning of the front end cover.

[0013] Preferably, clamping plates are rotatably fitted on both sides of the positioning groove. The two clamping plates are both connected to the positioning groove through a first elastic member and are symmetrically distributed. A stop block is provided on the outer side of the clamping plate. The stop block can abut against the shielding plate. The clamping plate can abut against the side wall of the lifting lug of the end cover.

[0014] 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.

[0015] Preferably, the positioning plate is detachably connected to the shielding plate through a bolt.

[0016] 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 processed front end cover.

[0017] 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 fitted 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. The limiting elastic ball can abut against the shielding plate.

[0018] The effect is that during the positioning process, the shielding plate moves inwards. The shielding plate can cross over the limiting ball and move to the inner side of the limiting ball. After the processing is completed, the shielding plate resets and opens outwards. During this process, the shielding plate abuts against the limiting 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 from the front end cover.

[0019] Preferably, a blanking port is provided on the workbench. The blanking port is located below the mounting seat. A discharge hopper is provided inside the frame. The discharge hopper is located below the blanking port, and the discharge hopper is inclinedly distributed.

[0020] The effect is that the front end cover will fall on the discharge hopper and be discharged from the frame along the discharge hopper.

[0021] 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.

[0022] Preferably, a collection box is provided below the discharge hopper.

[0023] A processing method for an aluminum motor front end cover, applied to the above-mentioned drilling processing device for an aluminum motor front end cover, includes the following steps:

[0024] The first step is loading. Place the lifting lug of the front end cover on the support rod of the positioning groove.

[0025] The second step is positioning. The lifting mechanism moves downwards, causing the push rod to gradually approach the dial and push the dial to rotate. The dial 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.

[0026] The third step is drilling. Drill the front end cover through the drilling mechanism.

[0027] The fourth step is blanking. The lifting mechanism moves upwards, the dial and the shielding plate reset, the positioning plate disengages from the front end cover, the pulling 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.

[0028] Place the lifting lugs of the front end cover in the positioning grooves, support the front end cover through the support plate. When the lifting mechanism moves downward, the push rod pushes the dial to rotate, the dial drives the push 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. 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.

[0029] Adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0030] According to the aluminum motor front end cover drilling and processing device and processing method of the present invention, place the lifting lugs of the front end cover in the positioning grooves, support the front end cover through the support plate. When the lifting mechanism moves downward, the push rod pushes the dial to rotate, the dial drives the push 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. 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.

In the initial state, a truncated cone-shaped structure is formed between the plurality of shielding plates 6, and the upper end of the truncated cone-shaped structure is the large diameter end.

[0045] 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 engaged 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 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.

[0046] As Figure 4 , Figure 5 and Figure 7 shown in the figure, clamping plates 13 are rotatably engaged 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.

[0047] 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 out of 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.

[0048] 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:

[0049] 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.

[0050] The second step is positioning. The first driving member 22 drives the lifting seat 21 to move downward, and the push rod 9 moves downward synchronously with the lifting seat 21. The push rod 9 gradually approaches the dial plate 7 and stops with it. The push rod 9 pushes the dial plate 7 to rotate while moving downward. 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 stop against the front end cover. At this time, the positioning plate 12 can clamp the front end cover, and the front end cover is coaxially distributed with the mounting seat 5. At the same time, during the rotation of the shielding plate 6, the shielding plate 6 also gradually approaches the block 132 and pushes the two blocks 132 in the same positioning groove to approach each other, so that the two clamping plates 13 approach each other, and clamp the ears of the front end cover to fix the front end cover. During the rotation process, the shielding plate 6 can also pass over the limiting pin 1123 and move to the inner side of the limiting pin 1123 .

[0051] The third step is drilling, in which the front end cover is drilled by the drilling mechanism 3 .

[0052] The fourth step is unloading. The first driving member 22 drives the lifting seat 21 to move upward, so that the push rod 9 is out of contact with the paddle plate 7. The paddle plate 7 is reset under the action of the second torsion spring, and the push plate 8 releases the limit of the shielding plate 6. The shielding plate 6 is reset under the action of the first torsion spring, and the top of the shielding plate 6 moves outward. The shielding plate 6 is stopped by the limit pin 1123, and the connecting rod 1122 and the second support rod 112 are pulled outward, so that the second support rod 112 gradually separates from the ear of the front end cover. Since only the first support rod 111 is in contact with the front end cover, the front end cover with the completed drilling is tilted and falls from the unloading port. After the front end cover is tilted, the processing debris scattered on its upper surface will slide off from the front end cover, and the front end cover finally falls on the discharge hopper 14 and is discharged from the frame 1 along the discharge hopper 14. The processing debris will also fall on the discharge hopper 14 and enter the collection box 15 through the sieve hole 141.
