[0002] During the manufacturing process of the motor housing, a sand-falling device is usually used to separate the housing from the molding sand. At present, the most widely used one is the vibrating sand-falling machine. The motor housing to be sanded is placed in the grid of the sand-falling machine table. The table vibrates under the action of the vibration motor.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0019] The present embodiment is an improvement made to address the technical problem that when the sand-falling processing equipment for motor casing castings is performing sand-falling processing on the motor casing castings, due to the fact that the sand-falling efficiencies of multiple motor casing castings are not completely consistent, the motor casing that has completed sand separation earlier will directly collide with the sand of the remaining motor casings that have not completed sand separation, thereby causing damage to the motor casing.

[0020] See also Figure 1-Figure 5 , Figure 7 The present embodiment provides a motor housing casting sand removal treatment device, comprising: A striking shaft 1, on the circumferential surface of which a plurality of striking hammers 2 are fixed, and the striking hammers 2 rotate synchronously with the striking shaft 1; The casting fixing cylinder 3 is used for positioning and installing the motor housing casting 33. The motor housing casting 33 is detachably arranged relative to the casting fixing cylinder 3. The casting fixing cylinder 3 is located below the knocking shaft 1. A slide rod 4, the slide rod 4 is fixedly connected to one end of the casting fixing tube 3; A circulating conveyor belt 5 is fixedly provided with a mounting plate 6, and a through hole is provided on the mounting plate 6 for the slide bar 4 to penetrate and slide. The circulating conveyor belt 5 drives the casting fixing cylinder 3 to move relative to the striking shaft 1 through the mounting plate 6. As the position of the casting fixing cylinder 3 moves, the striking shaft 1 drives the striking hammer 2 to rotate to strike the motor housing casting 33 moved thereunder, thereby completing the separation between the molding sand and the motor housing casting 33; When in use, the relative positions of the casting fixing cylinder 3 and the motor housing casting 33 are adjusted by sliding the slide bar 4 on the mounting plate 6. When the casting fixing cylinder 3 moves away from the mounting plate 6, the casting fixing cylinder 3 is embedded in the hollow cylinder of the motor housing to fix and install the motor housing casting 33. When the casting fixing cylinder 3 moves toward the mounting plate 6, the casting fixing cylinder 3 moves away from the motor housing to release the fixation of the motor housing casting 33, thereby realizing the unloading of the motor housing casting 33. A sleeve 7 is rotatably provided on the mounting plate 6, and the slide bar 4 is slidably provided in the sleeve 7. A guide protrusion 9 is fixedly provided on one of the sleeve 7 and the slide bar 4, and a guide slot is provided on the other of the sleeve 7 and the slide bar 4. The guide protrusion 9 is engaged and slidably provided in the guide slot, and the slide bar 4 and the sleeve 7 are synchronously moved by the cooperation of the guide protrusion 9 and the guide slot. It is worth noting that when the guide protrusion 9 is provided on the slide bar 4 and the guide groove is provided on the inner wall of the sleeve 7, in order to ensure the moving distance of the slide bar 4, the mounting plate 6 also needs to be provided with a guide groove for the guide protrusion 9 to slide through; A gear 8 is fixedly provided on the rack plate 10 and the sleeve 7, and the gear 8 meshes with the rack plate 10. When the slide bar 4 moves, the gear 8 is driven by the meshing of the rack plate 10 to rotate, and the slide bar 4 is driven by the gear 8 to rotate synchronously. When the slide bar 4 rotates synchronously with the gear 8, it drives the casting fixing tube 3 to rotate synchronously. When the casting fixing tube 3 rotates, it drives the motor housing casting 33 to rotate synchronously, so that the hammer 2 can knock different parts of the circumference of the motor housing casting 33, to ensure the uniformity of the knocking position of the outer molding sand of the motor housing casting 33, and to ensure the uniform separation of the molding sand.

[0021] Specifically, see Figure 2 , Figure 4 and Figure 5 In this embodiment, a motor casing casting sand removal processing equipment provided by the present invention also includes a load-bearing platform 11, a rack plate 10 is fixedly arranged on the load-bearing platform 11, and a circulating conveyor belt 5 is rotatably arranged on the load-bearing platform 11. The upper surface of the circulating conveyor belt 5 is not lower than the upper surface of the load-bearing platform 11 to avoid the load-bearing platform 11 interfering with the smooth movement of the mounting plate 6 with the circulating conveyor belt 5.

[0022] It is worth noting that the circulating conveyor belt 5 is a prior art, so its specific structure will not be described in detail in this solution.

[0023] Specifically, see Figure 7 In this embodiment, a ball 12 is rotatably provided on the lower surface of the mounting plate 6, and the mounting plate 6 is rolled on the load-bearing platform 11 through the ball 12. When the circulating conveyor belt 5 drives the mounting plate 6 to move its position, the load-bearing platform 11 plays a load-bearing supporting role for the mounting plate 6, and the setting of the ball 12 can improve the smoothness of movement of the mounting plate 6 on the load-bearing platform 11.

[0024] Specifically, see Figure 4 and Figure 6 In this embodiment, a loading and unloading mechanism is installed on the load-bearing platform 11, and the loading and unloading mechanism includes a rotating motor 13 and a rotating shaft 14. A support frame 15 is fixedly provided on the load-bearing platform 11, and the rotating motor 13 is arranged on the supporting frame 15. An active bevel gear 16 is fixedly provided on the output shaft of the rotating motor 13, and the rotating shaft 14 is rotatably arranged on the supporting frame 15. A driven bevel gear 17 is fixedly provided on the rotating shaft 14, and the driven bevel gear 17 is meshed with the active bevel gear 16. First magnets 18 are fixedly provided at both ends of the rotating shaft 14, and a second magnet 19 is fixedly provided at the free end of the slide bar 4. A reset spring 20 is sleeved on the slide bar 4, and both ends of the reset spring 20 are respectively connected to the mounting plate 6 and the second magnet 19, and the free end magnetic poles of the first magnet 18 and the second magnet 19 are opposite; The two groups of first magnets 18 correspond to the two groups of second magnets 19 at both ends of the circulating conveyor belt 5 respectively. When the first magnet 18 rotates to face the second electromagnet block, because the magnetic poles of the first magnet 18 and the second electromagnet block that are close to each other are opposite, the first magnet 18 absorbs the second magnet 19 through magnetic attraction, and pulls the casting fixing cylinder 3 to move toward the mounting block through the slide bar 4. During this movement, the fixing of the motor housing casting 33 by the casting fixing cylinder 3 is released, so that the loading and unloading of the motor housing casting 33 is realized; as the first magnet 18 rotates, when the first magnet 18 rotates away from the second magnet 19, due to the lack of magnetic attraction, the casting fixing cylinder 3 is driven by the slide bar 4 under the action of the reset spring 20 to be embedded into the motor housing casting 33, so that the motor housing casting 33 is fixed.

[0025] Specifically, see Figure 7-Figure 9In this embodiment, a mounting rod 21 is slidably provided on the side wall of the casting fixing cylinder 3, and a clamping plate 22 is fixedly provided at one end of the mounting rod 21 located outside the casting fixing cylinder 3. The outer surface of the clamping plate 22 is rough. When the clamping plate 22 contacts the inner wall of the motor housing casting 33, the consistency of the rotational movement of the motor housing casting 33 and the casting fixing cylinder 3 is ensured by the rough surface of the clamping plate 22. A sliding groove 23 is provided on the side wall of the casting fixing cylinder 3, and a fixed motor 24 is fixedly provided on the inner wall of the casting fixing cylinder 3. A driving screw 25 is connected to the output shaft of the fixed motor 24, and a threaded block 26 is threadedly connected to the driving screw 25. A pushing connecting rod 27 is hinged between the threaded block 26 and the clamping plate, and the pushing connecting rod 27 penetrates and slides in the sliding groove 23, and the sliding groove 23 serves as a limit for the pushing connecting rod 27.

[0026] During specific use, when the threaded block 26 slides along the driving screw 25, the connecting rod 27 is pushed to apply force to the clamping plate 22 to adjust the distance between the clamping plate 22 and the casting fixing tube 3. When the rough surface of the clamping plate 22 fits tightly with the motor housing casting 33, the installation of the motor housing casting 33 is completed.

[0027] Specifically, see Figure 7 and Figure 8 In this embodiment, at least two groups of sliding grooves 23 are provided on the circumference of the casting fixing cylinder 3, and the pushing connecting rod 27, the mounting rod 21 and the clamping plate 22 are all arranged corresponding to the sliding grooves 23, and the motor housing casting 33 is fixed by the cooperation of multiple groups of clamping plates 22.

[0028] Specifically, see Figure 2 In this embodiment, multiple groups of tapping shafts 1 are rotatable, one group of tapping shafts 1 is externally connected to the output shaft of the tapping motor 28, and two groups of belt pulleys are correspondingly fixed on two adjacent groups of tapping shafts 1. A group of driving belts 29 are sleeved on the two groups of belt pulleys. Under the action of the driving belts 29, multiple groups of tapping shafts 1 can be driven to rotate synchronously, and multiple groups of tapping shafts 1 cooperate to drive the tapping hammers 2 to tap and sand off the motor housing casting 33. Multiple groups of tapping hammers 2 are provided on the tapping shafts 1, and multiple points of tapping are performed along the axial direction of the motor housing casting 33 through the setting of multiple groups of tapping hammers 2.

[0029] Specifically, see Figure 2 In this embodiment, a plurality of casting fixing cylinders 3 are provided on the circulating conveyor belt 5. The plurality of casting fixing cylinders 3 are provided to continuously convey the motor housing casting 33, and the hammer 2 is used to knock and remove sand from the plurality of motor housing castings 33. A molding sand collecting bucket 30 is provided below the casting fixing cylinder 3. The casting fixing cylinder 3 is symmetrically arranged about the center line of the molding sand collecting bucket 30. The symmetrically arranged casting fixing cylinders 3 cooperate to fix the motor housing casting 33 from both ends.

[0030] It is worth noting that, in order to realize the recovery of molding sand, a crushing mechanism can be provided in the molding sand collecting bucket 30 to crush the molding sand dropped by the striking hammer 2 .

[0031] Specifically, see Figure 1 In this embodiment, a dust removal cover 31 is provided above the striking shaft 1, and the dust removal cover 31 is connected to an external dust removal pump through a dust removal pipe 32, so as to clean the molding sand dust generated during the striking process.

[0032] The working principle of the motor housing casting sand removal treatment device provided in this embodiment is as follows: (1) driving the circulating conveyor belt 5 to rotate. When the circulating conveyor belt 5 rotates, the casting fixing cylinder 3 is driven to move with it through the mounting plate 6. When one group of casting fixing cylinders 3 moves to the same lateral position as the first magnet 18, the driving bevel gear 16 is driven to rotate under the action of the rotating motor 13. The meshing of the driving bevel gear 16 and the driven bevel gear 17 drives the rotating shaft 14 to rotate. The rotating shaft 14 drives the first magnet 18 to rotate. When the first magnet 18 rotates to approach the second magnet 19, the first magnet 18 and the second magnet 19 have opposite magnetic poles. Under the action of magnetic attraction, the first magnet 18 attracts the second magnet 19, thereby driving the slide bar 4 to slide along the sleeve 7 and the mounting plate 6. The slide bar 4 drives the two groups of symmetrically arranged casting fixing cylinders 3 to move away from each other. (2) The motor housing casting 33 to be sanded is clamped by a human or mechanical arm and moved between the two sets of casting fixing cylinders 3 located at the head end of the circulating conveyor belt 5. Then, as the rotating motor 13 rotates, the first magnet 18 is driven away from the second magnet 19, and the casting fixing cylinder 3 is driven to move into the hollow inner cylinder of the motor housing casting 33 under the action of the return spring 20; At the same time, when the casting fixing cylinders 3 are moving away from each other, the two sets of casting fixing cylinders 3 located at the tail end of the circulating conveyor belt 5 release the fixing of the motor housing casting 33 therebetween, and the motor housing casting 33 that has been sanded off is automatically unloaded, and the unloaded motor housing casting 33 can be received by setting a transfer conveyor belt, and the motor housing casting 33 can be transferred; After the casting fixing cylinder 3 is installed, the casting fixing cylinder 3 and the motor housing casting 33 are moved under the action of the circulating conveyor belt 5, and the striking shaft 1 is driven to rotate in cooperation with the driving of the striking motor 28, and the rotating striking shaft 1 drives the striking hammer 2 to strike the motor housing casting 33 moved below it, and the molding sand on the motor housing casting 33 is separated to complete the sand falling process; the separated molding sand falls into the molding sand collecting bucket 30, and can be crushed by the crushing mechanism in the molding sand collecting bucket 30, and the molding sand dust generated in the separation process is adsorbed and cleaned by the dust removal cover 31 under the action of the dust removal pump while the striking separation. In the above working process, when the circulating conveyor belt 5 drives the mounting plate 6 to move, the mounting plate 6 rolls along the bearing platform 11 through the roller, and the bearing platform 11 plays the role of bearing support for the mounting plate 6.
