Description

Technical Field

[0001] This invention relates to the field of vacuum pump processing, specifically to a processing apparatus for a vacuum pump cover. Background Technology

[0002] A vacuum pump is a device that evacuates a container to create a vacuum. Vacuum pumps are mostly eccentric in structure, with a special shape and complex structure.

[0003] Currently, the processing method for vacuum pump covers is generally to manually position them and then grind them with equipment. When grinding different positions, manual repositioning is also required.

[0004] Therefore, the existing processing equipment for vacuum pump covers has the following drawbacks:

[0005] 1. Existing vacuum pump cover processing equipment has high labor costs and low automation. Since positioning is done manually, improper positioning is prone to occur during operation, resulting in low overall processing efficiency and quality.

[0006] 2. The existing vacuum pump cover processing equipment does not centrally and uniformly handle the waste generated during processing, which not only wastes a lot of time in subsequent cleaning operations, but also makes cleaning difficult and easily leads to poor cleaning results.

[0007] CN114789342A discloses an invention patent entitled "A Vacuum Pump Processing Equipment". When processing a vacuum pump, the invention first connects the first motor and the second motor to an external power supply, places the vacuum pump element inside the vertical plate, and fixes the vacuum pump element by the cooperation of the screw and the top block. Then, by the extension and retraction of the second cylinder, the circular plate and the ring plate are rotated and connected, and the hexagonal frame and the mounting sleeve are rotated and connected, so that the ring plate rotates 60 degrees at a time. The coupling is controlled to be inserted and connected with different mounting sleeves, thereby driving the grinding wheel, drill bit and brush to rotate and process the vacuum pump element. Through the meshing connection of the horizontal worm and the worm gear ring, the ring plate can be electrically controlled to rotate, thereby realizing automatic switching.

[0008] Its shortcomings are as follows: 1. After the screw and top block fix the vacuum pump element, if different end faces need to be processed, it is necessary to remove the screw and fix it again with the end face to be processed facing the processing direction. This not only wastes processing time, but also cannot guarantee positioning accuracy when re-fixing, resulting in poor processing quality. 2. The invention does not have a step for handling the waste generated after processing. This means that after processing one vacuum pump element, the fixing platform needs to be manually cleaned before continuing processing. Otherwise, it is easy for subsequent vacuum pump elements to have some waste stuck to them, resulting in poor processing quality. Summary of the Invention

[0032] Because of the adoption of the above technical solution, the present invention has the following advantages:

[0033] 1. This invention can realize the automatic flipping and grinding of vacuum pump cover, with a high degree of automation, which saves more time required for processing vacuum pump cover. It can also automatically collect and process the waste generated after grinding. The high degree of coordination between the two can ensure that the grinding process is not affected by waste, thus ensuring the quality of processing.

[0034] 2. This invention can process the inner hole of the pump cover, and during the grinding process, the first receiving plate can abut against the end face of one end of the inner hole, so that the waste generated during the grinding of the first grinding plate will not fall everywhere, but will fall accurately into the first receiving plate. When the fourth telescopic rod descends, the first telescopic ring extends out of the upper end face of the first receiving plate under the reset of the first spring, so that the inner wall of the first telescopic ring blocks the waste falling into the first receiving plate, which facilitates the subsequent centralized treatment of waste.

[0035] 3. The first receiving plate of the present invention can not only collect the waste generated when grinding the inner hole of the pump cover, but also block the third through hole when the first collecting plate receives the waste generated when grinding the end face of the pump cover. This allows the first collecting plate to collect the waste effectively. When the first collecting plate returns to its original position, the waste in the first grinding plate and the first receiving plate can rotate and transfer the waste in the first grinding plate and the waste collected during the grinding of the inner hole together to the first collecting plate through centrifugal force. This allows the first grinding plate and the first receiving plate to achieve different functions under different usage conditions, resulting in a good waste collection effect.

[0036] 4. When grinding the pump cover end face, the pump cover can be automatically flipped by the rotation of the first motor without manual adjustment, thus easily achieving grinding of both ends of the pump cover, making the device highly efficient.

[0037] Other advantages, objectives, and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination, or may be learned from practice of the invention. The objectives and other advantages of the invention can be realized and obtained from the following description and claims. Attached Figure Description

[0057] In this embodiment, at the start of operation, after the vacuum pump cover to be processed is transferred to the rotating fixing unit 3, the second telescopic rods 10 on both sides extend relative to each other, so that the first arc-shaped inclined surface 13 fits against the corresponding outer arc surface of the pump cover. Then, the third telescopic rod 17 retracts and pulls back the first clamping block 14, so that the upper end face of the first clamping block 14 and the lower end face of the first fixing block 11 clamp the corresponding two ends of the pump cover box, thereby fixing the pump cover and facilitating subsequent operations such as lifting, lowering, and rotating the pump cover. This invention can perform clamping, lifting, and flipping of the vacuum pump cover to be processed in an integrated manner, and all the functions can be completed by the rotating fixing unit 3, resulting in a high degree of overall integration and good performance.

The first mounting post 21 supports and drives the fifth telescopic rod 23, the first grinding disc 24, the first mounting plate 25, the first receiving plate 26, the first telescopic ring 27, etc., to move upwards together. During this movement, the second slider 28 on the first telescopic ring 27 contacts and presses against the lower end face of the pump cover, causing the first telescopic ring 27 to press until the upper end face of the second slider 28 is at the same height as the upper end face of the first receiving plate 26. The upper end face of the disc 26 abuts against the lower end opening of the inner hole of the pump cover. Then, the second motor 22 rotates, driving the first grinding disc 24 to rotate inside the inner hole of the pump cover. When rotating, the fifth telescopic rod 23 extends and retracts upward to grind the inner hole from bottom to top. Then, the fifth telescopic rod 23 retracts, and the first grinding disc 24 grinds the inner hole again from top to bottom. After grinding, the fourth telescopic rod 20 retracts, driving the first mounting column 21 to move downward. The first mounting column 21 supports and drives the fifth telescopic rod 23, the first grinding disc 24, the first mounting disc 25, the first receiving disc 26, the first telescopic ring 27, etc. to move downward together. When the first receiving disc 26 leaves the lower end face of the pump cover, the first telescopic ring 27 extends out of the upper end face of the first receiving disc 26 under the reset of the first spring 30, so that the inner wall of the first telescopic ring 27 blocks the waste debris falling into the first receiving disc 26. This invention can process the inner hole of the pump cover, and during the grinding process, the first receiving plate 26 can abut against the end face of one end of the inner hole, so that the waste generated during the grinding of the first grinding plate 24 will not fall everywhere, but will fall accurately into the first receiving plate 26. When the fourth telescopic rod 20 descends, the first telescopic ring 27 extends out of the upper end face of the first receiving plate 26 under the reset of the first spring 30, so that the inner wall of the first telescopic ring 27 blocks the waste falling into the first receiving plate 26, which facilitates the subsequent centralized treatment of waste.

[0063] like Figure 1 , Figure 4 , Figure 8 As shown, the first polishing unit 2 includes a third motor 35, a sixth telescopic rod 36, a first rotating disk 37, and a second polishing disk 38;

[0064] A first U-shaped mounting block 39 is fixedly connected to the upper hollow surface of the first mounting box 1. A fixed end of a third motor 35 is fixedly connected inside the first U-shaped mounting block 39. The rotating end of the third motor 35 is vertically downward. A fixed end of a sixth telescopic rod 36 is fixedly connected to the rotating end of the third motor 35. A first rotating disk 37 is fixedly connected to the fixed end of the sixth telescopic rod 36. The first mounting box 1 has a second through hole 40. A first rotating groove 41 is formed inside the second through hole 40. The first rotating disk 37 can rotate within the first rotating groove 41. The extended end of the sixth telescopic rod 36 is vertically downward and extends out of the lower hollow surface of the first mounting box 1. A second grinding disk 38 is fixedly connected to the extended end of the sixth telescopic rod 36.

[0065] In this embodiment, at the start of operation, the vacuum pump cover to be processed is conveyed to the rotating fixing unit 3 via the first conveyor belt 31. The second telescopic rod 10 extends and clamps and fixes the pump cover through the first arc-shaped inclined surface 13, the first clamping block 14, and the first fixing block 11. Then, the second grinding disc 38 grinds the inner hole of the vacuum pump cover. After the inner hole is processed, the first telescopic rod 7 extends, causing the pump cover to move upward. After the collecting unit 5 moves below the pump cover, the second grinding disc 38 rotates under the rotation of the third motor 35. Then, the sixth telescopic rod 36 extends downward, causing the lower end face of the second grinding disc 38 to rotate and contact the upper end face of the pump cover to be ground. After one end face is ground, the sixth telescopic rod 36 retracts, and the first motor 9 rotates, causing the pump cover to rotate 180 degrees, so that the other end face faces the second grinding disc 38. Then, the second grinding disc 38 descends again under the drive of the sixth telescopic rod 36 to grind the pump cover end face that has rotated to the upper end face. When grinding the pump cover end face, the pump cover can be automatically flipped by the rotation of the first motor 9 without manual adjustment, thus easily achieving grinding of both ends of the pump cover and making the device highly efficient.

[0066] like Figure 1 , Figure 5 As shown, the collecting unit 5 includes a seventh telescopic rod 42, a first mounting plate 43, a first collecting tray 44, a third slider 45, a fourth sliding groove 46, a first sliding seat 47, a first ball screw 48, a fourth motor 49, and a third through hole 50.

[0067] Two seventh telescopic rods 42 are fixedly connected inside the first mounting box 1. The extended ends of the seventh telescopic rods 42 are vertically upward. The seventh telescopic rods 42 are arranged on both sides of the second conveyor belt 32 and the third conveyor belt 78. The extended ends of the seventh telescopic rods 42 are fixedly connected to the lower end face of the first mounting plate 43. A first collecting tray 44 is provided between the opposite end faces of the two first mounting plates 43. A third through hole 50 is opened in the first collecting tray 44.

[0068] A third slider 45 is fixedly connected to both ends of the first collection tray 44 near the first mounting plate 43. A fourth sliding groove 46 is laterally opened on the opposite end face of the first mounting plate 43. The third slider 45 can slide in the fourth sliding groove 46. A first sliding seat 47 is fixedly connected to both ends of the first collection tray 44 near the first mounting plate 43. The first sliding seat 47 is threadedly connected to the first ball screw 48. The first ball screw is laterally fixed in the first mounting plate 43. One end of the first ball screw is fixedly connected to the rotating shaft of the fourth motor 49. The fourth motor 49 is fixed in the first mounting plate 43.

[0069] In this embodiment, at the start of operation, the vacuum pump cover to be processed is conveyed to the rotating fixing unit 3 via the first conveyor belt 31. The second telescopic rod 10 extends and clamps and fixes the pump cover through the first arc-shaped inclined surface 13, the first clamping block 14, and the first fixing block 11. Then, the first grinding disc 24 grinds the inner hole of the vacuum pump cover. After the inner hole is processed, the first telescopic rod 7 extends, causing the pump cover to move upward. Then, the fourth motor 49 rotates, driving the sliding seat to move towards the pump cover, so that the first collecting plate 44 and the sliding seat move together to the bottom of the pump cover. Before the second grinding disc 38 grinds the end face of the pump cover, the fourth telescopic rod 20 extends, driving the first mounting post 21 to move upward. The first mounting post 21 supports and drives the fifth telescopic rod 23, the first grinding disc 24, the first mounting plate 25, the first receiving plate 26, the first telescopic ring 27, etc., to move upward together. During the movement, the second telescopic ring 27 on the first telescopic ring 27... The slider 28 contacts and presses against the lower end face of the first collecting plate 44, causing the first telescopic ring 27 to press until the upper end face of the second slider 28 is at the same height as the upper end face of the first receiving plate 26. The first receiving plate 26 rises from the third through hole 50 until its upper end face is at the same height as the upper end face of the first receiving plate 26. After the second grinding block grinds the end face of the pump cover, when the pump cover rotates to grind the other end face, the waste generated during the rotation will be poured into the first collecting plate 44. After all the waste generated during the grinding is poured into the first collecting plate 44, the second motor 22 rotates and drives the first grinding plate 24 and the first receiving plate 26 to rotate, so that the waste in the first grinding plate 24 and the first receiving plate 26 is rotated onto the first collecting plate 44 by centrifugal force. Then, the first receiving plate 26 moves out of the third through hole 50 when the fourth telescopic rod 20 retracts. Then, the fourth motor 49 rotates and drives the sliding seat back to its original position, waiting for subsequent waste disposal. The first receiving plate 26 of the present invention can not only collect the waste generated when grinding the inner hole of the pump cover, but also block the third through hole 50 when the first collecting plate 44 receives the waste generated when grinding the end face of the pump cover. This allows the first collecting plate 44 to collect the waste effectively. When the first collecting plate 44 returns to its original position, the waste in the first grinding plate 24 and the first receiving plate 26 can rotate and transfer the waste in the first grinding plate 24 and the first receiving plate 26 together with the waste collected during the grinding of the inner hole to the first collecting plate 44 through centrifugal force. This allows the first grinding plate 24 and the first receiving plate 26 to achieve different functions under different usage conditions, and the usage effect is good.

[0070] like Figure 1 , Figure 5 , Figure 6 , Figure 7As shown, the waste processing unit 6 includes a fifth motor 51, a first gear 52, a first toothed plate 53, a second toothed plate 54, a fourth slider 55, a fifth slide groove 56, a fifth slider 57, a sixth slide groove 58, a second mounting plate 59, an eighth telescopic rod 60, a second mounting groove 61, a first stop block 62, a third mounting plate 63, a ninth telescopic rod 64, a third mounting groove 65, a second stop block 66, a first sliding plate 67, a seventh slide groove 68, a second ball screw 69, a second sliding seat 70, a sixth motor 71, a second sliding block 72, a first inclined surface 73, and a second inclined surface 74.

[0071] A fifth motor 51 is fixedly connected to each of the opposite end faces of the first mounting plate 43. The rotating ends of the fifth motor 51 are positioned opposite each other and extend out of the opposite end faces of the first mounting plate 43. A first gear 52 is rotatably fixed to the rotating end of the fifth motor 51, and the first gear 52 is located above the first collecting tray 44. A first toothed plate 53 is horizontally fixed to each of the opposite end faces of the first mounting plate 43. The first toothed plate 53 is located above the first gear 52 and meshes with the first gear 52. The two first toothed plates 53 are positioned opposite each other on their opposite end faces. A fourth slider 55 is provided, and a fifth slide groove 56 is laterally fixed to the first mounting plate 43, allowing the fourth slider 55 to slide within the fifth slide groove 56; a second toothed plate 54 is laterally fixed to each opposite end face of the first mounting plate 43, the second toothed plate 54 being located below and meshing with the first gear 52; a fifth slider 57 is provided on the opposite end faces of the two second toothed plates 54; a sixth slide groove 58 is laterally fixed to the first mounting plate 43, allowing the fifth slider 57 to slide within the sixth slide groove 58;

[0072] A second mounting plate 59 is fixedly connected to the end of each of the two first toothed plates 53 away from the second toothed plate 54. The lower end surface of the second mounting plate 59 is higher than the first collection tray 44. The second mounting plate 59 extends out of the opposite end surfaces of the two first toothed plates 53. A second mounting groove 61 is provided at the lower end of the second mounting plate 59. An eighth telescopic rod 60 is fixedly connected inside the second mounting plate 59. The extended end of the eighth telescopic rod 60 is vertically downward and extends out of the upper end surface of the second mounting groove 61. A first stop block 62 is fixedly connected to the extended end of the eighth telescopic rod 60, so the first stop block 62 can slide up and down in the second mounting groove 61.

[0073] Each of the two second toothed plates 54 is fixedly connected to a third mounting plate 63 at the end away from the first toothed plate 53. The lower end face of the third mounting plate 63 is higher than the first collecting tray 44. The third mounting plate 63 extends out of the opposite end faces of the two second toothed plates 54. A third mounting groove 65 is provided at the lower end of the third mounting plate 63. A ninth telescopic rod 64 is fixedly connected inside the third mounting plate 63. The extended end of the ninth telescopic rod 64 is vertically downward and extends out of the upper end face of the third mounting groove 65. A second stop 66 is fixedly connected to the extended end of the ninth telescopic rod 64, so the second stop 66 can slide up and down in the third mounting groove 65.

[0074] The first collection tray 44 is provided with two first sliding plates 67, which are horizontally arranged between the first mounting plate 43. The lower end face of the first sliding plate 67 is in contact with the upper end face of the first collection tray 44. The opposite end face of the first mounting plate 43 is provided with a seventh sliding groove 68, and the two first sliding plates 67 can slide in the seventh sliding groove 68.

[0075] In this embodiment, at the start of operation, the vacuum pump cover to be processed is conveyed to the rotating fixing unit 3 via the first conveyor belt 31. The second telescopic rod 10 extends and clamps the pump cover via the first arc-shaped inclined surface 13, the first clamping block 14, and the first fixing block 11. Then, the first grinding disc 24 grinds the inner hole of the vacuum pump cover. After the inner hole is processed, the first telescopic rod 7 extends, causing the pump cover to move upwards. Then, the first collecting disc 44 moves directly below the pump cover. The first receiving disc 26 temporarily fills the third through hole 50, thus cooperating with the first collecting disc 44 on the second grinding block. During end-face grinding of the pump cover, waste chips are collected. After collection, the first receiving plate 26 moves away from the third through hole 50, and then the first collecting plate 44 returns to its original position. Then, the eighth telescopic rod 60 and the ninth telescopic rod 64 move downwards, causing the first stop block 62 and the second stop block 66 to move to both sides of the first collecting plate 44. Then, the fifth motor 51 rotates forward, driving the first toothed plate 53 and the second toothed plate 54 to move relative to each other, thereby driving the first sliding plate 67 to move relative to each other. The two first sliding plates 67 stop when they reach the third through hole 50, thus initially completing the waste chip treatment. This invention can automatically empty the waste chips in the first collecting plate 44. The third through hole 50 not only temporarily fills and removes waste chips from the first receiving plate 26 and the first grinding plate 24, but also acts as a drain hole for emptying waste chips after collection. This allows the third through hole 50 to perform different functions in different scenarios, resulting in a better device performance.

[0076] like Figure 1 , Figure 7As shown, each of the two second sliding blocks 72 has a second sliding seat 70 fixedly connected to one end. The second sliding block 72 has a first inclined surface 73 and a second inclined surface 74. The first inclined surface 73 is located above the second inclined surface 74. The lower end of the second sliding block 72 is in contact with the upper end of the first collecting tray 44. The second sliding seat 70 is threadedly connected to the second ball screw 69. The second ball screw 69 is laterally fixed inside the first sliding plate 67. One end of the second ball screw 69 is fixedly connected to the rotating shaft of the sixth motor 71. The sixth motor 71 is fixedly connected to the first sliding plate 67. The second sliding blocks 72 on the two first sliding plates 67 are arranged on opposite sides of the first mounting plate 43.

[0077] In this embodiment, at the start of operation, the vacuum pump cover to be processed is conveyed to the rotating fixing unit 3 via the first conveyor belt 31. The second telescopic rod 10 extends and clamps the pump cover via the first arc-shaped inclined surface 13, the first clamping block 14, and the first fixing block 11. Then, the first grinding disc 24 grinds the inner hole of the vacuum pump cover. After the inner hole is processed, the first telescopic rod 7 extends, causing the pump cover to move upwards. Then, the first collecting disc 44 moves directly below the pump cover, and the first receiving disc 26 temporarily fills the third through hole 50 to cooperate with the first collecting disc 44 on the second grinding block. During end-face grinding of the cover, waste chips are collected. After collection, the first receiving plate 26 leaves the third through hole 50, and then the first collecting plate 44 returns to its original position. Then, the eighth telescopic rod 60 and the ninth telescopic rod 64 move downward, causing the first stop block 62 and the second stop block 66 to move down to both sides of the first collecting plate 44. Then, the fifth motor 51 rotates forward, driving the first toothed plate 53 and the second toothed plate 54 to move relative to each other, thereby driving the first sliding plate 67 and the second sliding block 72 to move relative to each other. The plate stops when the end faces of the two second sliding blocks 72 abut against the end face of the opposite first sliding plate 67. Then, the sixth motor 71 rotates forward, causing the second sliding seat 70 to move and drive the second sliding block 72 to rotate relative to it. It stops when the two opposite end faces of the second sliding block 72 contact each other, at which point it also stops above the third through hole 50, allowing all the waste on the first collection tray 44 to fall through the third through hole 50 onto the second conveyor belt 32 and the third conveyor belt 78. When the first sliding plate 67 and the second sliding block 72 reset, the eighth telescopic rod 60 and the ninth telescopic rod 64 move upward, causing the first stop block 62 and the second stop block 66 to move upward above the first collection tray 44. The fifth motor 51 continues to rotate forward, causing the first stop block 62 and the second stop block 66 to move between the two first sliding plates 67. Then, the eighth telescopic rod 60 and the ninth telescopic rod 64 move downward, causing the first stop block 62 and the second stop block 66 to move into the interior of the first collecting tray 44. Then, the fifth motor 51 reverses, driving the first toothed plate 53 and the second toothed plate 54 to move in the opposite direction, thereby driving the first sliding plate 67 back to its initial position. During the movement of the first sliding plate 67, the sixth motor 71 reverses, causing the second sliding block 72 to move in the opposite direction, and the second sliding block 72 also returns to its initial position. This invention can automatically dump the waste in the first collecting tray 44. Through the cooperation of the first sliding plate 67 and the second sliding block 72, all the waste in the first collecting tray 44 can be poured out through the third through hole 50. This allows the device to process waste without manual intervention and has good performance.

[0078] like Figure 1 , Figure 8 As shown, the device also includes a first collection box 75, a first mounting block 76, and a fourth conveyor belt 77;

[0079] A first mounting block 76 is provided on one side of the first collection box 75, and a fourth conveyor belt 77 is mounted on the first mounting block 76. The upper end face of the fourth conveyor belt 77 is at the same height as the upper end face of the second conveyor belt 32, and the input end of the fourth conveyor belt 77 corresponds to the output end of the second conveyor belt 32. The first collection box 75 is provided between the first mounting box 1 and the first mounting block 76, and the first collection box 75 is located below the output ends of the second conveyor belt 32 and the third conveyor belt 78 and the input end of the fourth conveyor belt 77.

[0080] In this embodiment, at the start of operation, the vacuum pump cover to be processed is conveyed to the rotating fixing unit 3 via the first conveyor belt 31. The second telescopic rod 10 extends and clamps the pump cover using the first arc-shaped inclined surface 13, the first clamping block 14, and the first fixing block 11. Then, the first grinding disc 24 grinds the inner hole of the vacuum pump cover. After the inner hole is processed, the first telescopic rod 7 extends, causing the pump cover to move upwards. The first collecting disc 44 then moves directly below the pump cover. The first receiving disc 26 temporarily fills the third through hole 50 to collect waste materials when the second grinding block grinds the end face of the pump cover. After collection, the first receiving disc 26 leaves the third through hole 50, and the first collecting disc 44 returns to its original position. The processed pump cover is then placed back onto the first conveyor belt 31 and the second conveyor belt 32. At this time, the seventh telescopic rod 42 moves upwards, causing the first mounting plate 43 to move upwards, which in turn moves the first collecting disc 44 upwards, leaving space for the pump cover to be conveyed on the second conveyor belt 32. The processed pump covers are then sequentially conveyed via the second conveyor belt 32. The conveyor belt 32 stops on the fourth conveyor belt 77, and after removal, proceeds to the next pump cover. Then, the eighth telescopic rod 60 and the ninth telescopic rod 64 move downwards, causing the first stop block 62 and the second stop block 66 to move to both sides of the first collection tray 44. Then, the fifth motor 51 rotates forward, driving the first toothed plate 53 and the second toothed plate 54 to move relative to each other, thereby causing the second sliding blocks 72 to move relative to each other. The second sliding blocks 72 stop when their end faces abut against the opposite end face of the first sliding plate 67. Then, the sixth motor 71 rotates, causing... The second sliding seat 70 moves, causing the second sliding block 72 to rotate relative to it. The second sliding block 72 stops when its two opposite end faces contact, also stopping above the third through hole 50. This allows all the waste debris on the first collecting tray 44 to fall through the third through hole 50 onto the second conveyor belt 32 and the third conveyor belt 78. The rotation of the second conveyor belt 32 and the third conveyor belt 78 causes the fallen waste debris to fall into the first collecting box 75, thus completing the final collection of waste debris. This invention can automatically complete the processing and collection of pump covers, as well as the automatic collection and handling of waste debris generated during processing, saving time in the upstream and downstream processes and making the overall production work more orderly.

[0081] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it.
