Description

Technical Field

[0001] This invention relates to a motor housing casting equipment with an edge burr grinding device, and more particularly to a motor housing casting equipment with an edge burr grinding device and its grinding method, belonging to the technical field of shearing and grinding machine tools. Background Technology

[0002] An electric motor is a device that converts electrical energy into mechanical energy. Its main function is to generate driving torque, serving as a power source for electrical appliances or various machines. The main components of an electric motor include the stator and the rotor. The stator core is part of the motor's magnetic circuit, on which the stator windings are placed. When three-phase alternating current is applied, a rotating magnetic field is generated. The rotor core is also part of the motor's magnetic circuit, and the rotor windings are placed in the core slots. Under the influence of the stator's rotating magnetic field, the rotor windings switch magnetic lines of force, generating induced electromotive force and current, and forming electromagnetic torque that causes the motor to rotate.

[0003] The motor housing is an important component of the motor. Existing motor housings require edge burr grinding before and after casting. However, existing edge burr grinding devices for motor housing casting can only adapt to a single shape of motor housing, which is not very adaptable. In addition, the grinding blocks will gradually wear down after a certain period of use, making them inconvenient to replace and wasting a lot of replacement time.

[0004] Therefore, it is urgent to improve the motor housing casting equipment to solve the above-mentioned problems. Summary of the Invention

[0011] Preferably, the inner side of the support plate is vertically provided with a second electric slide rail for driving the elastic element to slide. The elastic element includes a connecting block connected to the second electric slide rail and a sliding block slidably connected to the connecting block by a compression spring. The connecting block has a sliding groove inside, the compression spring is disposed inside the sliding groove and connected to the sliding block, and the connecting block is connected to the support frame.

[0012] Preferably, the support frame includes a second support plate, a top plate disposed above the inner side of the second support plate, and a third support plate connected to the lower end face of the second support plate via an electric telescopic rod. The lower end face of the second support plate has a hidden groove, and the electric telescopic rod is located in the hidden groove and connected to the third support plate.

[0013] Preferably, a plurality of grinding wheels are evenly distributed between the top plate and the third support plate. The lower end face of the grinding wheels is rotatably connected to the third support plate. The driving mechanism includes a second drive motor disposed on the upper end face of the top plate, a plurality of sprockets rotatably connected to the lower end face of the top plate and corresponding in number to the plurality of grinding wheels, and a chain for connecting the plurality of sprockets. The sprockets are rotatably connected to the top plate via rotating rods. The output end of the second drive motor is connected to one of the rotating rods. A magnetic suction limiting groove is provided on the lower end face of the rotating rod. A magnetic suction limiting block is provided on the upper end face of the grinding wheel and inserted into the magnetic suction limiting groove. The lower end face of the grinding wheel is rotatably connected to the third support plate via the second rotating rod.

[0014] Preferably, the outer side of the top plate is provided with a plurality of second sliding grooves corresponding to the number and position of the grinding wheels. The limiting mechanism includes a second compression spring disposed inside the second sliding groove and a warning block connected to the second compression spring and slidably connected to the second sliding groove. The outermost end of the warning block extends beyond the outer side of the second drive motor.

[0015] A grinding method for a motor housing casting equipment with an edge burr grinding device includes the following steps:

[0016] S1: After the circular motor housing is cast, it is placed on the clamping mechanism. Several electric slide rails drive several clamping blocks to slide inward synchronously until the motor housing is clamped and fixed. Then, the drive motor is turned on to rotate the rotating disk, which in turn rotates the clamped motor housing. When grinding the square motor housing, it is not necessary to turn on the drive motor. The square motor housing is kept in a fixed state, and direct contact grinding is performed using the grinding mechanism with up-and-down sliding adjustment on the outside.

[0017] S2: Then, the second drive motor is turned on to drive one of the sprockets to rotate. The chain is used to drive several grinding wheels to rotate synchronously. Then, the first drive motor is turned on to drive the lead screw to rotate, which in turn drives the support plate to slide inward, so that several support plates move closer to the motor housing. The grinding wheels directly contact the motor housing for grinding.

[0018] S3: During polishing, the running polishing mechanism is driven to slide up and down by the second electric slide rail, thereby polishing the outer surface of the motor housing in all aspects.

[0019] S4: After frequent grinding, the diameter of some grinding wheels will gradually decrease. When the motor housing begins to contact the limiting mechanism, the position of the grinding wheel needs to be replaced or adjusted. When replacing or grinding, use the extension of the electric telescopic rod to drive the third support plate below to move downwards, ensuring that there is enough space between the third support plate and the top plate to remove the grinding wheel. Pull the grinding wheel downwards until the magnetic limit block disengages from the magnetic limit groove. After removing the grinding wheel to be replaced, change its position or directly replace it with a new grinding wheel. During installation, use the magnetic limit block to insert into the magnetic limit groove on the upper end face of the grinding wheel and fix it with adsorption. Then, use the retraction of the electric telescopic rod to rotate and connect the second rotating rod on the lower end face of the grinding wheel to the third support plate.

[0020] The present invention has at least the following beneficial effects:

[0021] 1. After the circular motor housing is cast, it is placed on the clamping mechanism for clamping and fixing. The drive motor is turned on to rotate the rotating disk, which in turn rotates the clamped motor housing. The drive mechanism drives several grinding wheels to rotate synchronously. The first drive motor is turned on to rotate the lead screw, which in turn drives the support plate to slide inward, so that the support plate moves closer to the motor housing. The rotating grinding wheels directly contact the motor housing for grinding. During grinding, the second electric slide rail drives the running grinding mechanism to slide up and down, thereby grinding the outer surface of the motor housing in all directions. When grinding a square motor housing, it is not necessary to turn on the drive motor. The square motor housing is kept in a fixed state, and the grinding mechanism with up and down sliding adjustment on the outside can directly contact and grind.

[0022] 2. After frequent grinding, the diameter of some grinding wheels will gradually decrease, requiring replacement or adjustment. When replacing or grinding, extend the electric telescopic rod to move the third support plate downwards, pulling the grinding wheel down until the magnetic limit block disengages from the magnetic limit groove. Remove the grinding wheel to be replaced and reposition it, or replace it with a new one. During installation, insert the magnetic limit block into the magnetic limit groove on the upper surface of the grinding wheel for magnetic attraction and fixation. Then, retract the electric telescopic rod to rotate the second rotating rod on the lower surface of the grinding wheel to the third support plate.

[0023] 3. After a certain period of grinding, the diameter of the grinding wheel becomes smaller. When the motor housing comes into contact with the warning block, it indicates that the grinding wheel at the current position needs to be replaced, which serves as a good warning. The second compression spring prevents the motor housing from making hard contact with the warning block.

[0024] 4. When the grinding mechanism comes into contact with the motor housing, the elastic element will contract inward under pressure. By utilizing the effect of elasticity, it is ensured that the grinding mechanism can always keep in contact with the motor housing for grinding, while preventing hard contact between the grinding mechanism and the motor housing, thus preventing impact damage to the equipment.

[0036] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0037] like Figures 1-9 As shown, the edge burr grinding device for motor housing casting provided in this embodiment includes a support base 1 and a casting area 101. The casting area 101 includes a square motor housing casting cavity and a cylindrical motor housing casting cavity. A clamping mechanism 2 is rotatably connected to the upper end face of the support base 1. The clamping mechanism 2 includes a rotating disk 11 connected to the output end of the drive motor 9 and a plurality of clamping blocks 12 slidably connected on the rotating disk 11. A plurality of sliding grooves 13 are provided on the rotating disk 11. The plurality of sliding grooves 13 are in a cross structure. An electric slide rail 14 is provided in the sliding groove 13. The lower end face of the clamping block 12 is connected to the electric slide rail 14 through a slider 15. A rubber pad is provided on the inner side of the clamping block 12. The plurality of electric slide rails 14 drive the plurality of clamping blocks 12 to slide inward synchronously until the motor housing is clamped and fixed.

[0038] Furthermore, a rotating body 8 is rotatably connected to the outer surface of the clamping mechanism 2, and several support bodies 3 are provided on the outer side of the rotating body 8. The support bodies 3 are fixedly connected to the support base 1. A connecting ring 16 is provided on the outer side of the rotating disk 11, and an inner ring groove 17 that is slidably connected to the connecting ring 16 is provided on the inner side of the rotating body 8. Several support bodies 3 are evenly distributed on the outer side of the rotating body 8.

[0039] Furthermore, a support plate 4 is slidably provided on the upper end face of the support body 3, and an elastic element 5 is slidably provided on the inner side of the support plate 4. A second electric slide rail 22 for driving the elastic element 5 to slide is vertically provided on the inner side of the support plate 4. The elastic element 5 includes a connecting block 23 connected to the second electric slide rail 22 and a sliding block 40 slidably connected to the connecting block 23 through a compression spring 24. A sliding groove 25 is provided inside the connecting block 23. The compression spring 24 is provided inside the sliding groove 25 and connected to the sliding block 40. The connecting block 23 is connected to the support frame 601. When the grinding mechanism 6 contacts the motor housing, the elastic element 5 will be compressed inward under pressure. By utilizing the effect of elasticity, it is ensured that the grinding mechanism 6 can always contact the motor housing for grinding, and the grinding mechanism 6 will not make hard contact with the motor housing, thus preventing impact damage to the equipment.

[0040] A grinding mechanism 6 is connected via an elastic element 5. The grinding mechanism 6 includes a support frame 601 and several grinding wheels 602 driven by a drive mechanism. A limiting mechanism 7 is provided on the support frame 601. Several second sliding grooves 37 corresponding to the number and position of the grinding wheels 602 are opened on the outer side of the top plate 27. The limiting mechanism 7 includes a second compression spring 38 disposed inside the second sliding groove 37 and a warning block 39 connected to the second compression spring 38 and slidably connected to the second sliding groove 37. The outermost end of the warning block 39 extends beyond the outer side of the second drive motor 41. After the grinding wheel 602 has been grinding for a certain period of time, its diameter becomes smaller. When the motor housing contacts the warning block 39, it indicates that the grinding wheel 602 at the current position needs to be replaced. The setting of the second compression spring 38 can prevent the motor housing from making hard contact with the warning block 39.

[0041] A drive motor 9 is fixedly installed on the upper end face of the support base 1. The output end of the drive motor 9 is fixedly connected to the lower end face of the clamping mechanism 2. Several support rods 10 are provided on the outer side of the support base 1 and fixedly connected to the lower end face of the support body 3. The drive motor 19 is turned on to drive the rotating disk 11 to rotate, thereby driving the clamped motor housing to rotate. The support rods 10 can effectively prevent the outer rotating body 8 from rotating with it.

[0042] The upper end face of the support body 3 is provided with a second sliding groove 18. A first drive motor 19 is fixedly installed on the outside of the support body 3. The output end of the first drive motor 19 passes through the inside of the second sliding groove 18 and is connected to a lead screw 20. The lower end face of the support plate 4 is provided with a second slider 21 that is slidably connected to the second sliding groove 18 and threadedly connected to the lead screw 20. The first drive motor 19 is turned on to drive the lead screw 20 to rotate, thereby driving the support plate 4 to slide inward, so that several support plates 4 move closer to the direction of the motor housing, and the directly rotating grinding wheel 602 contacts and grinds the motor housing.

[0043] Furthermore, the support frame 601 includes a second support plate 26, a top plate 27 disposed above the inner side of the second support plate 26, and a third support plate 29 connected to the lower end face of the second support plate 26 via an electric telescopic rod 28. The lower end face of the second support plate 26 is provided with a hidden groove 30, and the electric telescopic rod 28 is located in the hidden groove 30 and connected to the third support plate 29.

[0044] Furthermore, several grinding wheels 602 are evenly distributed between the top plate 27 and the third support plate 29. The lower end face of the grinding wheels 602 is rotatably connected to the third support plate 29. The driving mechanism includes a second drive motor 41 disposed on the upper end face of the top plate 27, several sprockets 31 rotatably connected to the lower end face of the top plate 27 and corresponding in number to the several grinding wheels 602, and a chain 32 for connecting the several sprockets 31. The sprockets 31 are rotatably connected to the top plate 27 through rotating rods 33. The output end of the second drive motor 41 is connected to one of the rotating rods 33. The opening of the second drive motor 41 drives one of the sprockets 31 to rotate, and the chain 32 drives the several grinding wheels 602 to rotate synchronously.

[0045] Furthermore, a magnetic suction limiting groove 34 is provided on the lower end face of the rotating rod 33, and a magnetic suction limiting block 35 is provided on the upper end face of the grinding wheel 602, which is inserted into the magnetic suction limiting groove 34. The lower end face of the grinding wheel 602 is rotatably connected to the third support plate 29 through the second rotating rod 36. When some grinding wheels 602 are frequently ground, their diameter will gradually decrease. When the motor housing begins to contact the limiting mechanism 7, it is necessary to replace or adjust the position of the grinding wheel 602. During replacement or grinding, the extension of the electric telescopic rod 28 is used to drive the lower third support plate 29 to move downwards. Ensure there is enough space between the third support plate 29 and the top plate 27 to remove the grinding wheel 602. Pull the grinding wheel 602 downwards until the magnetic limiting block 35 disengages from the magnetic limiting groove 34. After removing the grinding wheel 602 that needs to be replaced, change its position or directly replace it with a new grinding wheel 602. During installation, insert the upper end face of the grinding wheel 602 into the magnetic limiting groove 34 using the magnetic limiting block 35 and fix it with adsorption. Then, use the retraction of the electric telescopic rod 28 to rotate and connect the second rotating rod 36 on the lower end face of the grinding wheel 602 to the third support plate 29.

[0046] A grinding method for a motor housing casting equipment with an edge burr grinding device includes the following steps:

[0047] S1: After the circular motor housing is cast, it is placed on the clamping mechanism 2. Several electric slide rails 14 drive several clamping blocks 12 to slide inward synchronously until the motor housing is clamped and fixed. Then, the drive motor 19 is turned on to drive the rotating disk 11 to rotate, which in turn drives the clamped motor housing to rotate. When grinding the square motor housing, it is not necessary to turn on the drive motor 19 to keep the square motor housing in a fixed state. The grinding mechanism 6 with up and down sliding adjustment on the outside can be used for direct contact grinding.

[0048] S2: Then, the second drive motor 41 is turned on to drive one of the sprockets 31 to rotate. The chain 32 drives several grinding wheels 602 to rotate synchronously. Then, the first drive motor 19 is turned on to drive the lead screw 20 to rotate, which in turn drives the support plate 4 to slide inward, so that several support plates 4 move closer to the motor housing. The rotating grinding wheels 602 directly contact the motor housing for grinding. It should be noted that after several grinding mechanisms 6 move closer to each other, there will still be enough space to ensure that several grinding mechanisms 6 do not contact each other.

[0049] S3: During polishing, the second electric slide rail 22 drives the running polishing mechanism 6 to slide up and down, thereby polishing the outer surface of the motor housing in all aspects.

[0050] S4: After frequent grinding, the diameter of some grinding wheels 602 will gradually decrease. When the motor housing begins to contact the limiting mechanism 7, the grinding wheels 602 need to be replaced or adjusted. When replacing or grinding, the extension of the electric telescopic rod 28 is used to drive the lower third support plate 29 downward, ensuring that there is enough space between the third support plate 29 and the top plate 27 to remove the grinding wheel 602. Pull the grinding wheel 602 downward until the magnetic limit block 35 disengages from the magnetic limit groove 34. After removing the grinding wheel 602 that needs to be replaced, its position can be changed or a new grinding wheel 602 can be directly replaced. During installation, the upper end face of the grinding wheel 602 is inserted into the magnetic limit groove 34 using the magnetic limit block 35 and fixed by adsorption. Then, the retraction of the electric telescopic rod 28 is used to rotate the second rotating rod 36 on the lower end face of the grinding wheel 602 to the third support plate 29.

Several electric slide rails (14) drive several clamping blocks (12) to slide inward synchronously until the motor housing is clamped and fixed. Then, the drive motor (9) is turned on to drive the rotating disk (11) to rotate, thereby driving the clamped motor housing to rotate. When polishing the square motor housing, it is not necessary to turn on the drive motor (9) to keep the square motor housing in a fixed state. The polishing mechanism (6) with up and down sliding adjustment on the outside can be used for direct contact polishing. S2: Then, the second drive motor (41) is turned on to drive one of the sprockets (31) to rotate. The chain (32) is used to drive several grinding wheels (602) to rotate synchronously. Then, the first drive motor (19) is turned on to drive the lead screw (20) to rotate, which in turn drives the support plate (4) to slide inward, so that several support plates (4) move closer to the motor housing. The grinding wheel (602) that rotates directly contacts the motor housing for grinding. S3: During polishing, the running polishing mechanism (6) is driven up and down by the second electric slide rail (22) to polish the outer surface of the motor housing in all aspects. S4: After frequent grinding, the diameter of some grinding wheels (602) will gradually decrease. When the motor housing begins to contact the limiting mechanism (7), it is necessary to replace or adjust the position of the grinding wheel (602). When replacing or grinding, the extension of the electric telescopic rod (28) is used to drive the lower third support plate (29) to move downward, and ensure that the space between the third support plate (29) and the top plate (27) is sufficient to remove the grinding wheel (602). Pull the grinding wheel (602) downward until... After the magnetic limiting block (35) is disengaged from the magnetic limiting groove (34), the grinding wheel (602) that needs to be replaced is removed and its position is changed or a new grinding wheel (602) is directly replaced. During installation, the upper end face of the grinding wheel (602) is inserted into the magnetic limiting groove (34) using the magnetic limiting block (35) and then fixed by adsorption. Afterwards, the second rotating rod (36) on the lower end face of the grinding wheel (602) is rotated and connected to the third support plate (29) by the retraction of the electric telescopic rod (28).
