Description

Technical Field

[0001] The present invention relates to the technical field of motor casing production equipment, and more specifically to a motor casing production device. Background Art

[0002] The motor housing usually has several complex shapes and its internal structure is relatively complex. Sand casting technology can realize these complex structures more easily than other molding technologies, and the casting technology can be completed in one molding. At the same time, during the casting process, a variety of metal alloys can be selected to meet different mechanical properties and durability. On the other hand, casting can achieve efficient mass production and can quickly manufacture a large number of relatively complex shapes, thereby meeting the needs of large-scale production of motor housings.

[0003] During the casting production process of the motor casing, the factory needs to separate the motor casing from the molding sand through the sand dropping equipment after the pouring is completed to ensure that the cast motor casing has good surface quality and precision. At present, most factories use vibration or impact to separate the molding sand and the motor casing. However, due to the special shape of some motor casings, the molding sand inside the motor cannot be separated inside the motor casing. Since the separation of the motor casing and the molding sand in the prior art mainly adopts the left-right vibration and the up-and-down vibration, but because one end of some motor casings is closed, the internal molding sand cannot be separated, and thus remains inside the motor casing to form sand holes. At the same time, the molding sand may hinder the air flow inside the motor casing and affect the heat dissipation effect of the motor casing, thereby causing changes in its internal stress to affect product quality. For this reason, the motor casing needs to be separated for a second time, which results in the need to remove the molding sand that has been retained for a long time during subsequent processing. At the same time, it will increase the difficulty of subsequent processing of the motor casing, thereby reducing the production efficiency of the motor casing.

[0004] In view of the above situation, the present invention designs a motor casing production device to solve the above technical problems. Summary of the invention

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0022] refer to Figure 1 , Figure 5 , Figure 6 , Figure 8 As shown, a motor housing production device includes a metal smelting device for melting various metal materials, a pouring device for pouring the smelted metal solution, a sand cleaning device for separating the molding sand and the motor housing after pouring, and a surface treatment device for precision processing the surface of the motor housing, the molding sand cleaning device includes an equipment body 1, a vibration component 2 is arranged on the equipment body 1, a support vertical plate 3 is installed above the vibration component 2, the support vertical plate 3 is symmetrically arranged above the vibration component 2, and the vibration component 2 is connected to the sand falling plate 4 through the support vertical plate 3, the vibration component 2 drives the sand falling plate 4 to make the workpiece jump up and down and move left and right, and a reversing component 5 is arranged inside the sand falling plate 4, and the reversing component 5 includes a reversing motor 51, a threaded rod 52, a sliding sleeve 53 and an ejector block 54; the front end position of the sand falling plate 4 is vertical A reversing rod 41 is arranged on the frame, a reversing rod 41 is arranged at the rear end of the sand falling plate 4 parallel to the frame, and a reversing assembly 5 is arranged in the middle of the sand falling plate 4; reversing motors 51 are symmetrically arranged on both sides of the sand falling plate 4, the output end of the reversing motor 51 is connected to a threaded rod 52, a sleeve 53 is installed on the outer circumferential surface of the threaded rod 52, and an ejection block 54 is connected to the end of the sleeve 53 away from the reversing motor 51; the vibration assembly 2 drives the sand falling plate 4 to move, and the workpiece passes through the reversing rod 41 arranged at the front end of the sand falling plate 4, so that the workpiece is parallel and perpendicular to the frame of the sand falling plate 4, and when the workpiece contacts the ejection block 54, the reversing motor 51 drives the threaded rod 52 to make the ejection block 54 at one end of the sleeve 53 contact with the inside of the workpiece, and the workpiece is parallel to the reversing rod 41 arranged at the rear end of the sand falling plate 4 through the continuous movement of the sand falling plate 4.

[0023] During the working process, the operator first needs to select suitable metal materials for smelting according to the performance and purpose of the motor casing, and at the same time, it is necessary to add additives to the metal smelting equipment to ensure the performance of the motor casing. After the metal is smelted, the metal solution is poured into the pre-prepared sand mold through the pouring equipment. After the pouring is completed, wait for the metal to solidify. After solidification, the molding sand and the motor casing are separated by the molding sand cleaning equipment. The separated motor casing is surface treated by the surface treatment equipment. After the surface treatment, the motor casing is collected and packaged. When the molding sand cleaning equipment separates the molding sand and the motor casing, the staff first starts the vibration component 2 to drive the sand falling plate 4. Since the vibration component 2 and the sand falling plate 4 are connected by the supporting vertical plate 3, the sand falling plate 4 moves to one end while shaking up and down under the drive of the vibration component 2. The setting of the upper reversing rod 41 enables the motor housing to change from being perpendicular to the sand falling plate 4 to being parallel to the sand falling plate 4 during movement. When the motor housing moves to the front end position of the ejector block 54, the reversing motor 51 is started, and the rotation of the reversing motor 51 drives the coaxially installed threaded rod 52 to rotate, thereby causing the sliding sleeve 53 to move forward on the threaded rod 52. Since the sliding sleeve 53 is fixedly connected to the ejector block 54, the ejector block 54 extends into the motor housing at this time. However, since the sand falling plate 4 keeps moving at this time, one end of the motor housing is restricted in displacement and the other end moves. After the continuous movement of the sand falling plate 4, one end of the motor housing opening is directed toward the entrance of the motor housing, and the motor housing is parallel to the sand falling plate 4 at this time. Since the opening of the motor housing faces different directions, reversing components 5 are provided on both sides of the sand falling plate 4 at this time, thereby ensuring that the motor housing can complete the reversal, thereby improving the internal molding sand cleaning effect.

[0024] refer to Figure 2 , Figure 3 , Figure 4 As shown, the vibration component 2 includes a base plate 21, a fixed plate 22, a motion frame 23, a moving column 24, a motion spring 25, a motion block 26 and a control wheel 27. Fixed plates 22 are provided at both ends of the base plate 21, and a motion frame 23 is provided in the middle of the fixed plates 22 at both ends. The motion frame 23 is concave, and the moving columns 24 are symmetrically installed on both sides of the motion frame 23, and the moving columns 24 are arranged through the fixed plates 22. A motion spring 25 is provided on the circumferential surface of the moving column 24 between the fixed plate 22 and the motion frame 23. A motion block 26 is installed inside the motion frame 23, and control wheels 27 are provided on both sides of the motion block 26. The motion block 26 drives the motion block 26 to move up and down through the rotation of the control wheel 27, and the rotation of the control wheel 27 drives the motion frame 23 to move left and right.

[0025] During the working process, when the moving block 26 is moved by the rotation of the control wheel 27, when the moving block 26 is displaced left and right, since the moving block 26 is completely in contact with the two sides of the moving frame 23, the moving block 26 drives the moving frame 23, so that the moving columns 24 arranged on both sides of the moving frame 23 move on the fixed plate 22. During the movement, the moving frame 23 squeezes the moving spring 25 to achieve buffering. At the same time, the moving spring 25 can also increase the kinetic energy of the return stroke of the moving frame 23, so that the left and right displacement of the falling sand plate 4 can be achieved, so that the molding sand inside the motor housing falls off. The shape of the control wheel 27 is semicircular, and the control wheel 27 is symmetrically arranged on both sides of the moving block 26, and the two control wheels 27 are symmetrically arranged on both sides of the moving block 26. The rotation directions of the side control wheels 27 are consistent, and the control wheels 27 are connected to the drive motor 264. The control wheels 27 are driven to rotate by the rotation of the drive motor 264. Since the shape of the control wheels 27 is semicircular, and the rotation directions of multiple control wheels 27 are consistent, when the semicircular control wheel 27 turns to one side of the motion block 26, the motion block 26 will move to the semicircular side of the control wheel 27. At this time, the semicircular control wheel 27 can realize different motion directions of the motion block 26, so that the motion block 26 drives the sand falling plate 4 to move the motor housing from one end to the other end, and the motor housing can be shaken up and down, so that the molding sand adhered to the motor housing falls off.

[0026] refer to Figure 3 As shown, a mounting cavity 261 is provided inside the motion block 26, and a driving motor 264 is provided in the mounting cavity 261. The output end of the driving motor 264 passes through the motion block 26, and the output end of the driving motor 264 is connected to a control wheel 27. The control wheels 27 are symmetrically arranged on both sides of the motion block 26, and a plurality of control wheels 27 are provided. Limit rods 262 are provided on the upper and lower sides of the motion block 26, and a limit spring 263 is installed on the circumferential surface of the limit rod 262.

[0027] During operation, the coaxially arranged control wheel 27 is driven to rotate by the driving motor 264. The rotation of the control wheel 27 can drive the moving block 26 to move up, down, left and right. When the moving block 26 moves up and down, the limit rods 262 arranged on the upper and lower sides of the moving block 26 will pass through the upper and lower ends of the moving frame 23 and move. At this time, the moving block 26 squeezes the limit spring 263. The limit spring 263 can accelerate the kinetic energy of the return stroke of the moving block 26 while achieving buffering, thereby increasing the movement amplitude of the sand falling plate 4.

[0028] refer to Figure 5 , Figure 6 , Figure 7 As shown, the reversing assembly 5 also includes a limit block 55 and a fixed structure 56. The limit blocks 55 are arranged on both sides of the ejection block 54, and the limit blocks 55 are triangular in shape. The widest sides of the limit blocks 55 on both sides correspond to each other, and the limit blocks 55 are in contact with the ejection block 54, and one side of the limit block 55 is connected to the fixed structure 56.

[0029] During operation, when the sand dropping plate 4 drives the motor housing to move, when the motor housing moves all the way to the limit block 55, the motor housing will move along the surface of the limit block 55. At the same time, the limit blocks 55 arranged on both sides of the sand dropping plate 4 can limit the movement direction of the motor housing to avoid the motor housing from being offset. When the motor housing moves to the front end of the ejector block 54, the ejector block 54 extends to limit one end of the motor housing, and the other end of the motor housing continues to move due to the lack of the ejector block 54 restriction. As a result, the motor housing changes from being perpendicular to the sand dropping plate 4 to being parallel to the sand dropping plate 4. After the direction change is completed, the fixed structure 56 can ensure that the position of the motor housing remains unchanged, avoiding position offset during movement and the situation where the molding sand remaining inside the motor housing cannot escape from the inside of the housing.

[0030] The fixed structure 56 includes a guide plate 561, a limit plate 562 and a control spring 563. The guide plate 561 is arranged on one side of the limit block 55, and the guide plate 561 is symmetrically arranged on the sand falling plate 4 in a trumpet shape. The guide plate 561 is tilted on the sand falling plate 4. One side of the guide plate 561 is connected to the limit plate 562, and the limit plates 562 on both sides are parallel. The limit plate 562 is connected to both sides of the sand falling plate 4 through the control spring 563. When the electrode shell continues to move through the sand falling plate 4 after the steering is completed, the guide plate 561 contacts first, The guide plate 561 can guide the restricted end and the unrestricted end of the motor casing to be parallel to the sand dropping plate 4. At the same time, the motor casing is squeezed by the guide plate 561 to control the spring 563 to move. When the two ends of the motor casing are parallel to the sand dropping plate 4 and one end of the motor casing is not restricted, the control spring 563 is not squeezed and returns to the initial state. The control spring 563 pushes the limit plate 562 to move the motor casing to the other side of the limit plate 562. Through the impact of the limit plates 562 on both sides, the residual molding sand inside the motor casing can fall off, thereby ensuring the effect of cleaning the molding sand of the motor casing.

[0031] The front end of the sand falling plate 4 is arranged parallel to the bottom plate 21, and the rear end of the sand falling plate 4 is arranged at an inclined angle to the bottom plate 21, and the reversing rod 41 arranged at the front end part of the sand falling plate 4 is perpendicular to the two sides of the sand falling plate 4, and the reversing rod 41 arranged at the rear end part of the sand falling plate 4 is parallel to the two sides of the sand falling plate 4. Through such an arrangement, the sand falling plate 4 can make the motor housing move to the front of the ejection block 54 and be perpendicular to the sand falling plate 4 during the displacement process, ensuring that the ejection block 54 can extend into the motor housing to complete the turning. The arrangement of the rear end part of the sand falling plate 4 can ensure that the motor housing is facing downward after the motor housing completes the turning, ensuring that the residual molding sand in the motor housing can be discharged evenly to avoid affecting the product quality.

[0032] The reversing rods 41 are provided with multiple groups, and the contact parts of the reversing rods 41 and the workpiece are provided with arc surfaces 43, and connecting blocks 42 are provided between two adjacent reversing rods 41. The number of connecting blocks 42 depends on the length of the reversing rods 41. By providing the connecting blocks 42, the connection strength of the reversing rods 41 can be improved. At the same time, the arc surfaces 43 provided on the reversing rods 41 can make the motor housing better limited by the reversing rods 41, and at the same time avoid the situation where the motor housing is damaged by the reversing rods 41.

[0033] The connecting block 42 is provided with an arc surface 43 which is the same as the reversing rod 41 at the contact position between the connecting block 42 and the workpiece, and a sand falling hole 421 is provided on the connecting block 42. The shape of the sand falling hole 421 is an inverted cone 422 with a small inlet and a large outlet. Through such an arrangement, when the molding sand falls on the connecting block 42, the molding sand is prevented from being blocked on the connecting block 42, so that the molding sand can flow out evenly.

[0034] Distance sensors 57 are provided on the upper and lower sides of the ejection block 54. The distance sensors 57 are used to detect the distance between the ejection block 54 and the inside of the motor housing, and use the sensing condition as a signal to control the start and stop of the reversing motor 51. The distance sensor 57 can detect the distance between the ejection block 54 and the motor housing. When the distance sensor 57 on one side detects that the distance between the ejection block 54 and the motor housing is greater than the distance sensor 57 on the other side, the distance sensor 57 on the side with the longer detection distance controls the reversing motor 51 to start.

[0035] The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
