DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the embodiments of the present application. Figure 1-Figure 7 , the technical scheme of the embodiment of the present application is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present application, not all of the embodiments. Based on the described embodiment of the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

[0027] Reference Figure 1 and Figure 2 This embodiment provides a motor housing grinding device, including a frame 1, a grinding mechanism 2, a positioning mechanism 4, a clamping body 5, a driving member, a displacement assembly and a driving assembly 6.

[0028] The grinding mechanism 2 is a belt grinder in the prior art, which is mainly composed of a grinding motor, a driving wheel, a tensioning wheel, a transmission wheel and a propulsion cylinder; the positioning mechanism 4 is used to correct the skewed material so that the side of the material remains parallel to the belt on the grinding mechanism 2 before grinding; the driving member is used to drive the clamping body 5, and the clamping body 5 can clamp the material from the inside of the material in an outward expansion manner; the displacement assembly is used to drive the positioning mechanism 4, the clamping body 5 and the driving assembly 6 to move left and right, thereby realizing the transfer of the material; the driving assembly 6 is used to drive the clamping body 5 to move up and down and rotate along the axial direction.

[0029] Among them, refer to Figure 4 and Figure 6 The positioning mechanism 4 includes a hydraulic cylinder 41, a connecting frame 42, a side plate 43 and a guide plate 44. The connecting frame 42 is arranged at the output end of the hydraulic cylinder 41, there are two side plates 43, the two side plates 43 are located on both sides of the clamping body 5, the side plates 43 are arranged at the bottom of the connecting frame 42, and the guide plate 44 is arranged at an angle at the bottom of the side plate 43, and the side view structure of the two guide plates 44 is in an "eight" shape.

[0030] Before the clamping body 5 fixes the material, the hydraulic cylinder 41 drives the side plate 43 and the guide plate 44 to move downward through the connecting frame 42. The guide plate 44 opened in an "eight" shape can twist the deflected material so that its side is parallel to the side plate 43. Because the side plate 43 is parallel to the sanding belt on the grinding mechanism 2, under the action of the positioning mechanism 4, the motor housing can remain parallel to the sanding belt on the grinding mechanism 2.

[0031] Among them, refer to Figure 3 and Figure 5 The clamping body 5 includes a mounting member 501 , a supporting plate 502 , a lifting rod 504 , a pressing block 505 , a connecting groove 506 , an inserting block 507 , a second spring 508 and an inclined plate 509 . The mounting member 501 is arranged at the bottom of the connecting rod 65, and the connecting groove 506 is circumferentially arranged inside the mounting member 501. The connecting grooves 506 are symmetrically distributed at the top and bottom of the mounting member 501, so that both ends of the support plate 502 can be connected to the mounting member 501, which helps to improve the stability of the support plate 502. The plug block 507 and the second spring 508 are arranged inside the connecting groove 506, one end of the second spring 508 is fixedly connected to the mounting member 501, and the other end is fixedly connected to the plug block 507, the support plate 502 is fixedly connected to the plug block 507, the inclined plate 509 is arranged on one side of the support plate 502, the lifting rod 504 is movably sleeved inside the connecting rod 65, the pressing block 505 is arranged at the bottom of the lifting rod 504, the outer inclined surface of the pressing block 505 is adapted to the inclined plate 509, and the outer inclined surface of the pressing block 505 abuts against the inclined plate 509, and the driving member is the second cylinder 510.

[0032] After the mounting member 501 enters the material, the output end of the second cylinder 510 drives the lifting rod 504 to move downward, and the lifting rod 504 squeezes the pressing block 505 to expand the circumferentially arranged support plates 502 of the mounting member 501 outward. At this time, the second spring 508 is in a stretched state, and the multiple support plates 502 expand circumferentially and contact the inner wall of the motor housing to clamp and fix the motor housing.

[0033] Among them, refer to Figure 3 The driving assembly 6 includes a third cylinder 61, a bottom plate 62, a rotating cylinder 63, a movable frame 64 and a connecting rod 65. The bottom plate 62 is arranged at the output end of the third cylinder 61, the movable frame 64 is rotatably connected to the upper surface of the bottom plate 62, the second cylinder 510 is arranged inside the movable frame 64, the connecting rod 65 is arranged at the bottom of the movable frame 64 and is fixedly connected to the mounting member 501, the connecting rod 65 penetrates the bottom plate 62 and is rotatably connected thereto, and the rotating cylinder 63 for driving the movable frame 64 to rotate is fixedly connected to the bottom plate 62.

[0034] The output end of the third cylinder 61 drives the base plate 62 to move up and down in the axial direction, and the base plate 62 drives the clamping body 5 to move up and down through the connecting rod 65; when the motor housing has completed the grinding of the two surfaces, the third cylinder 61 drives the base plate 62 to move the clamping body 5 and the motor housing upward, so that the two are moved out from between the grinding mechanisms 2, and then the rotating cylinder 63 drives the movable frame 64 to rotate the connecting rod 65 90 degrees, and the connecting rod 65 drives the clamping body 5 to rotate the motor housing 90 degrees, thereby realizing the turning over of the motor housing. The motor housing does not need to be repositioned after the turning over, and then under the action of the third cylinder 61, the motor housing moves down to the grinding position to continue the grinding operation.

[0035] Among them, refer to Figure 1 The displacement assembly includes a support frame 3, a cross plate 31, a screw rod 32, a motor 33, a slide rod 34 and a slide table 35. The positioning mechanism 4 and the driving assembly 6 are both arranged on the slide table 35. The cross plate 31 is fixedly connected to the top of the support frame 3. The slide table 35 is threadedly connected to the screw rod 32. The motor 33 is used to drive the screw rod 32 to rotate. The slide table 35 is movably sleeved on the slide rod 34. The hydraulic cylinder 41 and the third cylinder 61 are both fixedly connected to the slide table 35. An opening for the rotating cylinder 63 and the movable frame 64 to pass through is arranged on the side of the slide table 35 close to the clamping body 5.

[0036] The motor 33 drives the screw rod 32 to rotate to move the slide 35 along the transverse plate 31 , thereby causing the positioning mechanism 4 , the clamping body 5 and the driving assembly 6 to move left and right along the transverse plate 31 , thereby realizing the transfer of the motor housing.

[0037] In addition, refer to Figure 6 and Figure 7A cavity 47 is provided on the side plate 43, a scraper 48 is provided inside the cavity 47, the side surface of the scraper 48 is located in the same plane as the side plate 43, a movable part 46 is provided above the scraper 48, and a first cylinder 45 for driving the movable part 46 to move longitudinally is provided on the side plate 43.

[0038] After the guide plate 44 corrects the posture of the motor housing, the first cylinder 45 drives the movable part 46 to move downward, and the movable part 46 drives the scraper 48 to move downward. At this time, as the side plate 43 moves downward, the scraper 48 can scrape off the larger burrs remaining on the surface of the motor housing, creating good conditions for subsequent grinding work.

[0039] Reference Figure 4 A kit 420 is provided at the bottom of the connecting frame 42 and is sleeved on the outside of the clamping body 5 and the driving assembly 6. A bidirectional lead screw 421 is provided on the kit 420. The side plate 43 is slidably provided on the kit 420 and is threadedly connected with the bidirectional lead screw 421.

[0040] Rotating the two bidirectional lead screws 421 simultaneously can move the two side plates 43 in opposite or facing directions simultaneously, so that the distance between the two side plates 43 can be adjusted according to the size of the motor housing, reducing the limitations of the device and making it more flexible and convenient to use.

[0041] Reference Figure 6 and Figure 7 A mounting groove 440 is provided at the bottom of the side plate 43, and a first spring 442 and a support bar 441 are provided inside the mounting groove 440. The support bar 441 is movably connected in the mounting groove 440 through the first spring 442, and the top and bottom of the side of the support bar 441 close to the scraper 48 are both inclined surfaces.

[0042] When the scraper 48 is inside the cavity 47, the inclined surface at the bottom of the support bar 441 is at the same level as the guide plate 44, preventing the motor housing from being stuck in the gap between the scraper 48 and the guide plate 44 during positioning. When the scraper 48 moves downward, under the action of the top inclined surface of the support bar 441, the support bar 441 squeezes the first spring 442 and enters the mounting groove 440. Under the action of the first spring 442, the support bar 441 always fits one side of the scraper 48, preventing the scraped burrs from entering the knife groove.

[0043] Reference Figure 5 An air bag body 503 in contact with the inside of the motor housing is provided on the support plate 502.

[0044] When clamping the motor housing, the airbag body 503 can be deformed under force, which can not only fit the inner wall of the motor housing and be suitable for motor housings of different sizes, but also increase the contact area with the motor housing to ensure the clamping effect and avoid damage to the motor housing due to excessive clamping force.

[0045] Reference Figure 1 A loading conveyor belt 7 and a unloading conveyor belt 8 are respectively arranged on the left and right sides of the frame 1.

[0046] The width of the loading conveyor belt 7 and the unloading conveyor belt 8 is equal to or less than the size of the motor housing to avoid interference with the positioning mechanism 4; by cooperating with the loading conveyor belt 7 and the unloading conveyor belt 8, the device can replace manual loading and unloading, improve the degree of automation, and help improve production efficiency.

[0047] The implementation principle of a motor housing grinding device in the embodiment of the present application is: After the feeding conveyor belt 7 transports the motor housing to the specified position, the hydraulic cylinder 41 drives the connecting frame 42 to move the side plate 43 and the guide plate 44 downward. During this process, the guide plate 44 adjusts the posture of the skewed motor housing. Then the first cylinder 45 drives the movable part 46 to move the scraper 48 out. The scraper 48 moves downward with the side plate 43 and scrapes off the larger burrs; then the third cylinder 61 drives the bottom plate 62 and the connecting rod 65 to move the clamping body 5 downward. After the clamping body 5 enters the motor housing, the output end of the second cylinder 510 drives the lifting rod 504 to move downward. The lifting rod 504 squeezes the pressing block 505 to expand the circumferential support plate 502 of the mounting member 501 outward. At this time, the second spring 508 is in a stretched state. After the multiple support plates 502 expand circumferentially, they contact the inner wall of the motor housing to clamp and fix the motor housing. At this time, the positioning mechanism 4 moves up and resets.

[0048] The motor 33 drives the screw rod 32 to move the slide 35, and the slide 35 drives the driving assembly 6 and the clamping body 5 to move the motor housing between the two grinding mechanisms 2 to grind the two side surfaces of the motor housing. After the grinding of the two surfaces is completed, the third cylinder 61 drives the base plate 62 to move the clamping body 5 and the motor housing upward, so that the two are moved out from between the grinding mechanisms 2. Then the rotating cylinder 63 drives the movable frame 64 to rotate the connecting rod 65 90 degrees, and the connecting rod 65 drives the clamping body 5 to rotate the motor housing 90 degrees to realize the flipping of the motor housing. The motor housing after flipping does not need to be repositioned. Then, under the action of the third cylinder 61, the motor housing moves down to the grinding position to continue the grinding operation; finally, under the action of the displacement assembly, the polished motor housing is transferred to the unloading conveyor belt 8 and transported to the next process for processing via the unloading conveyor belt 8.

[0049] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0050] The above is a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
