Description

Technical Field

[0001] The present invention relates to the field of motor aluminum shell processing, and particularly relates to a cutting and grinding machine tool for motor aluminum shell processing. Background Art

[0002] Since aluminum has excellent thermal conductivity and a relatively low density, it can effectively conduct the heat generated during the operation of the motor and reduce the weight of the overall equipment, making it convenient for handling and installation. Therefore, aluminum alloy is commonly used to prepare the existing motor shells.

[0003] During the processing of the motor aluminum shell, it is usually extruded from a mold through a heating and high-pressure extrusion device to form a 100-aluminum shell profile with a certain cross-sectional shape of the motor shell. Then, according to the size of the motor shell, the extruded 100-aluminum shell profile is cut into segments to obtain the motor aluminum shell, and then the cut and segmented motor aluminum shell is polished. However, there are several heat dissipation fins for motor heat dissipation on the outer surface of the 100-aluminum shell profile. In order to have a higher heat dissipation efficiency, the thickness of the heat dissipation fins is relatively thin, and the aluminum material has good plasticity and ductility. Currently, the 100-aluminum shell profile is usually directly placed on a flat support table for cutting. During the process of cutting the 100-aluminum shell profile into segments, the 100-aluminum shell profile is supported by the heat dissipation fins, and a relatively large pressure is applied to the 100-aluminum shell profile during cutting, making the heat dissipation fins of the 100-aluminum shell profile prone to deformation during cutting. Moreover, the deformation of the heat dissipation fins of the 100-aluminum shell profile will also cause the position of the 100-aluminum shell profile to change, thereby affecting the cutting accuracy of the 100-aluminum shell profile.

[0004] At the same time, after cutting the 100-aluminum shell profile into motor aluminum shells of corresponding sizes, when grinding the burrs on the cutting surface of the motor aluminum shell, it is necessary to manually reposition and adjust the motor aluminum shell and use additional grinding equipment to grind it, resulting in low overall processing efficiency of the motor aluminum shell; moreover, the 1001-spacing grooves between the heat dissipation fins of the motor aluminum shell are relatively narrow, making it inconvenient for manual grinding of the flanging burrs at this location. Summary of the Invention

[0005] In order to overcome the drawback that the existing equipment applies a relatively large pressure to the 100-aluminum shell profile during cutting, making the heat dissipation fins of the 100-aluminum shell profile prone to deformation during cutting and causing the position of the 100-aluminum shell profile to change, thereby affecting the cutting accuracy of the 100-aluminum shell profile, the present invention provides a cutting and grinding machine tool for motor aluminum shell processing.

Detailed implementation manners

[0029] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0030] Embodiment 1

[0031] A cutting and grinding machine tool for processing aluminum shells of motors, as Figures 1 - 3 shown, includes a workbench 1, a housing 2, a placement plate 3, an electric slide 4 and a cutting unit; the workbench 1 is fixedly connected to the housing 2; the housing 2 is connected to the cutting unit; the workbench 1 is fixedly connected to the placement plate 3; the placement plate 3 is slidably connected to the electric slide 4 through a slide rail; a blanking port 01 is opened on the workbench 1;

[0032] It also includes a moving unit, a support frame 6, a first support block 7 and an inner support unit; the workbench 1 is connected to the moving unit; the moving unit is connected to the support frame 6, and the moving unit is used to drive the support frame 6 to move; a number of first support blocks 7 equal to the number of spacing grooves 1001 of the aluminum shell profile 100 are fixedly connected inside the support frame 6; the moving unit is connected to the inner support unit.

[0033] The cutting unit includes a first hydraulic push rod 5, a connecting plate 51, an asynchronous motor 52 and a cutting disc 53; four first hydraulic push rods 5 are fixedly connected to the housing 2; each corresponding two first hydraulic push rods 5 are fixedly connected with a connecting plate 51 at their telescopic parts; two connecting plates 51 are jointly rotatably connected to a cutting disc 53; an asynchronous motor 52 is fixedly connected to one of the connecting plates 51, and the output shaft of the asynchronous motor 52 is fixedly connected to the cutting disc 53.

[0034] It also includes a first rechargeable electric push rod 8, a movable frame 9 and a second support block 10; two first rechargeable electric push rods 8 are fixedly connected to the bottom of the support frame 6; the telescopic parts of all the first rechargeable electric push rods 8 are jointly fixedly connected to a movable frame 9, and a number of second support blocks 10 equal to the number of spacing grooves 1001 of the aluminum shell profile 100 are fixedly connected inside the movable frame 9.

[0035] A chamfer is opened on the right side of the movable frame 9 to facilitate the movement and insertion of the aluminum shell profile 100 into the movable frame 9.

[0036] The moving unit includes an electric guide rail 101, a first electric slider 102 and a second electric slider 103; two electric guide rails 101 are fixedly connected to the workbench 1; each electric guide rail 101 is slidably connected to a first electric slider 102, and the two first electric sliders 102 are jointly fixedly connected to the support frame 6; each electric guide rail 101 is slidably connected to a second electric slider 103, and the two second electric sliders 103 are jointly connected to the inner support unit.

[0037] Initially, the electric skateboard 4 is located at the rightmost end of the placement plate 3. When processing the motor aluminum shell, first, the artificially extruded aluminum shell profile 100 is placed on the placement plate 3, and the electric skateboard 4 is controlled to move into contact with the right side of the placed aluminum shell profile 100. Then, the electric skateboard 4 is controlled to move leftward along the slide rail on the placement plate 3. The electric skateboard 4 pushes the aluminum shell profile 100 to move leftward. When the aluminum shell profile 100 moves to the length required for cutting a single motor aluminum shell, the electric skateboard 4 is controlled to stop moving. Then, the hydraulic push rod 5 is controlled to drive the connecting plate 51, the asynchronous motor 52, and the cutting blade 53 to move downward, and at the same time, the asynchronous motor 52 is controlled to drive the cutting blade 53 to rotate. The aluminum shell profile 100 below is cut and segmented by the rotation and downward movement of the cutting blade 53, thereby cutting out the motor aluminum shell of the corresponding size. After cutting is completed, the cutting blade 53 is controlled to move back to its original position, and the electric skateboard 4 is again controlled to drive the aluminum shell profile 100 to move leftward for cutting the next motor aluminum shell, while the previously cut motor aluminum shell falls out through the blanking port 01 of the workbench 1.

[0038] Considering that there are several heat dissipation fins for motor heat dissipation on the outer surface of the aluminum shell profile 100, during cutting, the aluminum shell profile 100 is supported by the heat dissipation fins, and the aluminum shell profile 100 will be subjected to a relatively large pressure, making the heat dissipation fins of the aluminum shell profile 100 prone to deformation during the cutting process, thereby affecting the cutting accuracy of the aluminum shell profile 100. Therefore, when the electric skateboard 4 pushes the aluminum shell profile 100 to move leftward, the electric slider 102 is controlled to drive the support frame 6 to move rightward along the electric guide rail 101, approaching the left end of the aluminum shell profile 100. As the electric skateboard 4 continuously pushes the aluminum shell profile 100 to move leftward, the aluminum shell profile 100 moves into and penetrates the support frame 6, and during the process of the aluminum shell profile 100 inserting into the support frame 6, at the same time, the support block 7 on the support frame 6 inserts into the spacing groove 1001 of the aluminum shell profile 100. At this time, the aluminum shell profile 100 is jointly supported by the placement plate 3 and the support frame 6. During the cutting process, the electric slider 102 is controlled to drive the support frame 6 to move to the left of the cutting blade 53. When the cutting blade 53 moves downward for cutting, the outer surface of the aluminum shell profile 100 is jointly supported by the support frame 6 and the support block 7, preventing all the pressure on the aluminum shell profile 100 from acting on the heat dissipation fins, which easily causes the heat dissipation fins to deform. And during cutting, the heat dissipation fins are supported and limited by the support block 7, further preventing the heat dissipation fins from deforming, thereby ensuring the cutting accuracy of the motor aluminum shell. When cutting is completed, the electric skateboard 4 is continuously controlled to drive the aluminum shell profile 100 to move, insert the aluminum shell profile 100 into the support frame 6 again, and push out the cut motor aluminum shell from the support frame 6 through the aluminum shell profile 100, making it fall through the blanking port 01.

[0039] Meanwhile, it is considered that when the cutting disc 53 cuts, a large amount of heat will be generated due to the contact friction between the cutting disc 53 and the aluminum shell profile 100, resulting in local softening of the aluminum shell profile 100. And during the cutting process, a relatively large force will be exerted on the heat sinks of the aluminum shell profile 100, resulting in easy deformation of the heat sinks at the aluminum shell profile 100 after cutting. When the heat sinks are deformed, it will be difficult for the support frame 6 and the first support block 7 to insert the aluminum shell profile 100. Therefore, a movable frame 9 is also provided. When the electric skateboard 4 drives the aluminum shell profile 100 to move and insert into the support frame 6, the aluminum shell profile 100 first inserts and penetrates through the movable frame 9 and then inserts into the support frame 6. During cutting, the storage battery electric push rod 8 is controlled to drive the movable frame 9 to move, so that there is a certain interval between the support frame 6 and the movable frame 9, and the interval is located directly below the cutting disc 53. During cutting, the heat sinks at both ends of the cutting are supported and protected by the support frame 6 and the movable frame 9, so as to avoid the deformation of the heat sinks of the aluminum shell profile 100 during the cutting process. After cutting, the movable frame 9 moves to fit with the support frame 6, and through the guidance of the movable frame 9, it is also convenient for the electric skateboard 4 to push the aluminum shell profile 100 to move and insert into the support frame 6 again.

[0040] Embodiment 2

[0041] On the basis of Embodiment 1, as Figures 2 - 8 shown, the inner support unit includes a moving plate 111, an AC motor 112, a rotating disc 113, a rotating rod 114, a mounting circular plate 115, an arc-shaped support plate 116 and a storage battery electric push rod two 117; two electric sliders two 103 are commonly fixed with a moving plate 111; the moving plate 111 is rotatably connected with a rotating disc 113; the moving plate 111 is fixed with an AC motor 112, and the output shaft of the AC motor 112 is fixed with the rotating disc 113; the rotating disc 113 is fixed with a rotating rod 114; the rotating disc 113 is fixed with a mounting circular plate 115; the mounting circular plate 115 is slidably connected with six arc-shaped support plates 116 distributed in a circular array, and the arc-shaped support plates 116 are made of heat-conducting materials; the rotating rod 114 is fixed with a number of storage battery electric push rods two 117, and the telescopic parts of every two corresponding storage battery electric push rods two 117 are commonly fixed with an arc-shaped support plate 116.

[0042] It also includes a pipeline 121, a suction pipe 122 and an annular pipe 123; each arc-shaped support plate 116 is respectively provided with two suction channels 11601; the rotating rod 114 is fixed with a pipeline 121; the pipeline 121 is communicated with a number of suction pipes 122, and the suction pipes 122 are communicated with the suction channels 11601; the rotating disc 113 is arranged in a hollow shape, and the pipeline 121 is fixed and communicated with the rotating disc 113; the moving plate 111 is fixed with an annular pipe 123, the annular pipe 123 is rotatably connected and communicated with the rotating disc 113, and the annular pipe 123 is communicated with an external pump.

[0043] Chamfers are provided on the right sides of the first support block 7 and the second support block 10, facilitating the movement of the first support block 7 and the second support block 10 into the spacing grooves 1001 of the aluminum shell profile 100.

[0044] It also includes a second hydraulic push rod 131, an electric gripper 132, a grinding disc 133, a clamping block 134, a battery-powered third electric push rod 135 and a push plate 136; two second hydraulic push rods 131 are fixedly connected to the housing 2; an electric gripper 132 is fixedly connected to the telescopic part of each second hydraulic push rod 131; all the electric grippers 132 jointly hold a grinding disc 133; a clamping groove 11602 is formed on the surface of each arc-shaped support plate 116; the inner ring surface of the grinding disc 133 is fixedly connected with clamping blocks 134 having the same number as the clamping grooves 11602; three battery-powered third electric push rods 135 distributed in an annular array are fixedly connected to the rotating disc 113; a push plate 136 is fixedly connected to the telescopic part of each battery-powered third electric push rod 135.

[0045] Both sides of the grinding disc 133 are provided as grinding surfaces, capable of simultaneously grinding and removing the burrs on both sides after cutting, improving the overall processing efficiency.

[0046] It also includes a battery-powered fourth electric push rod 201 and a grinding roller 202; a through groove 11604 is formed on each arc-shaped support plate 116; two battery-powered fourth electric push rods 201 are fixedly connected to each arc-shaped support plate 116; all the telescopic parts of the battery-powered fourth electric push rods 201 on the same arc-shaped support plate 116 are jointly fixedly connected with a grinding roller 202, and the grinding roller 202 is located at the through groove 11604.

[0047] The arc-shaped support plate 116 is provided with a plurality of suction ports 11603, and the suction ports 11603 are communicated with the suction channel 11601. Through the suction ports 11603, the debris generated by grinding can be evacuated, preventing the debris from accumulating on the surface of the arc-shaped support plate 116 and affecting its subsequent support effect.

[0048] Based on the above-mentioned Embodiment 1, during the process of cutting the aluminum shell profile 100, the debris generated by cutting will fall inside the aluminum shell profile 100 and sputter outwards along the inner wall of the aluminum shell profile 100. The scattered sputtering of the debris is likely to affect the operation of the equipment. In response to this, when the aluminum shell profile 100 is moved and inserted into the support frame 6, at the same time, the electric slider two 103 is controlled to drive the moving plate 111, the rotating disk 113, the rotating rod 114, the mounting circular plate 115, the arc-shaped support plate 116, and other connected parts to move to the right, driving the arc-shaped support plate 116 to move into the interior of the aluminum shell profile 100, and the arc-shaped support plate 116 is located on the left side of the cutting position of the aluminum shell profile 100 to avoid hindering subsequent cutting. Then, the storage battery electric push rod two 117 is controlled to drive the arc-shaped support plate 116 to move and expand, so that the arc-shaped support plate 116 moves to fit the inner wall of the aluminum shell profile 100. At this time, the interior of the aluminum shell profile 100 is supported synchronously by the arc-shaped support plate 116. Compared with the prior art where there is a lack of effective support for the cutting of the aluminum shell profile 100, which may cause the aluminum shell profile 100 to be sunken or deformed during the cutting process, the present invention supports the interior and exterior of the aluminum shell profile 100 simultaneously through the arc-shaped support plate 116 and the support frame 6, further ensuring the stability during the cutting of the aluminum shell profile 100 and avoiding the situation where the aluminum shell profile 100 is locally stressed and deformed. And, during the process of the cutting blade 53 cutting the aluminum shell profile 100, the external pump is controlled to sequentially pass through the annular pipe 123, the rotating disk 113, the pipe 121, and the suction pipe 122 to suck the cutting part of the aluminum shell profile 100 from the suction channel 11601 of the arc-shaped support plate 116, and timely extract the debris that has fallen inside the aluminum shell profile 100 to prevent the generated debris from sputtering everywhere and affecting the operation of the equipment. At the same time, the arc-shaped support plate 116 fits the inner wall of the aluminum shell profile 100, and the arc-shaped support plate 116 is made of a heat-conducting material. During the process of the suction channel 11601 sucking the debris, it drives the gas flow. When a large amount of heat is generated during the cutting of the aluminum shell profile 100 by the cutting blade 53, the heat is conducted through the arc-shaped support plate 116, and combined with the air flow driven by the suction of the suction channel 11601, the heat generated by cutting is taken away to cool the cutting part of the aluminum shell profile 100, avoiding the situation where the cutting part of the aluminum shell profile 100 is overheated, resulting in melting or deformation on the surface of the aluminum shell profile 100 and affecting the overall cutting quality.

[0049] Moreover, after the aluminum shell profile 100 is cut into the motor aluminum shell, it is necessary to grind and remove the burrs on the cutting surface of the motor aluminum shell. When grinding, it is necessary to manually reposition and adjust the motor aluminum shell, and use additional grinding equipment to grind it, resulting in low processing efficiency of the overall motor aluminum shell. Therefore, after the cutting blade 53 completes the cutting of a single motor aluminum shell, control the cutting blade 53 to move upward for reset. Then, control the electric slider one 102 and the electric slider two 103 to synchronously drive the support frame 6, the arc-shaped support plate 116, and the cut motor aluminum shell to move to the left, so that the cut motor aluminum shell is separated from the aluminum shell profile 100 to be cut by a certain space. Then, control all the storage electric push rods two 117 to drive the arc-shaped support plate 116 to move and converge towards the middle, separating from the inner wall of the cut motor aluminum shell. Control the electric slider two 103 to drive the arc-shaped support plate 116 to move to the right, so that the card slot 11602 of the arc-shaped support plate 116 moves to the right side of the cut motor aluminum shell. At the same time, control the hydraulic push rod two 131 to drive the electric gripper 132 and the grinding disc 133 to move downward, so that the grinding disc 133 moves downward to be on the same axis as the rotating rod 114, as Figure 7As shown, then control the second electric slider 103 to drive the arc-shaped support plate 116 to move closer to the grinding disc 133. Stop moving when the card slot 11602 is directly opposite to the clamping block 134 of the grinding disc 133. Then control all the second storage battery electric push rods 117 to drive the arc-shaped support plate 116 to move outwards and expand, so that the arc-shaped support plate 116 moves into contact with the inner ring surface of the grinding disc 133. At this time, the clamping block 134 is inserted into the card slot 11602, and the arc-shaped support plate 116 is clamped with the grinding disc 133. Then control the electric gripper 132 to release the grinding disc 133, and control the third storage battery electric push rod 135 to drive the push plate 136 to push the motor aluminum shell between the arc-shaped support plate 116 and the support frame 6 to move to the right, so that the cutting surface of the motor aluminum shell fits with the grinding disc 133. Then control the AC motor 112 to drive the rotating disc 113, the arc-shaped support plate 116 and the grinding disc 133 to rotate at a speed of 300 revolutions per minute. With the support and fixation of the support frame 6, the cutting surface of the motor aluminum shell after cutting is polished by the grinding disc 133 to remove burrs. And during the polishing process, the support frame 6 is used again to support and fix the motor aluminum shell during the polishing process. When the polishing is completed, control the second electric slider 103 to drive the arc-shaped support plate 116 and the grinding disc 133 to move to the right, so that the other side of the grinding disc 133 fits with the cutting surface of the aluminum shell profile 100, and control the grinding disc 133 to rotate to polish and remove the burrs on the other cut surface after cutting. In this way, compared with the existing method that requires repositioning and polishing of the motor aluminum shell after cutting, the processing efficiency is low. The present invention can directly and quickly clamp the grinding disc 133 and the arc-shaped support plate 116 to polish the burrs on the cut surface after cutting, without spending extra manpower and material resources. It can not only improve the overall processing efficiency, but also save a lot of manpower. After the polishing is completed, control the second hydraulic push rod 131 to drive the electric gripper 132 to move downwards and clamp the grinding disc 133 again. Then control the arc-shaped support plate 116 to move and contract, so that the card slot 11602 is separated from the clamping block 134 for quick disassembly. Then control the second hydraulic push rod 131 to drive the grinding disc 133 to move back to its original position, and drive the push plate 136 to move through the third storage battery electric push rod 135 to push the polished motor aluminum shell to fall, and it falls through the blanking port 01.

[0050] Meanwhile, after the motor aluminum shell is cut, there are still flanging burrs that bend inward into the internal spacing groove 1001. Moreover, there are many heat sinks on the surface of the motor aluminum shell, and the spacing grooves 1001 between the heat sinks are relatively narrow, making it difficult for manual labor to grind and remove the flanging burrs at this location. Therefore, before the grinding piece 133 performs grinding, first control all the energy storage electric push rods II 117 to drive the arc-shaped support plate 116 to move and expand to support and fix the inner wall of the motor aluminum shell. Then, control the electric slider I 102 to drive the support frame 6 and the first support block 7 to move reciprocally. Through the reciprocal movement of the first support block 7, with the support of the arc-shaped support plate 116, the first support block 7 pushes out the flanging burrs at the spacing groove 1001 of the motor aluminum shell. When the subsequent grinding piece 133 grinds and removes the burrs, it can fully remove the burrs generated by cutting, reduce subsequent reprocessing, improve the overall processing efficiency of the motor aluminum shell, and the reciprocal movement of the first support block 7 can also push out the debris that has fallen on the spacing groove 1001, avoiding the inconvenience of manual cleaning of the debris that has fallen between the heat sinks due to the narrow space between the heat sinks. After the subsequent grinding piece 133 finishes grinding, then control the push plate 136 to move to push down the ground motor aluminum shell. When the present invention performs cutting, the support frame 6 and the arc-shaped support plate 116 synchronously support the outside and inside of the aluminum shell profile 100, which can not only prevent the heat sinks of the aluminum shell profile 100 from deforming during cutting, ensure the overall cutting accuracy, but also effectively clean the outer surface and inner surface of the aluminum shell profile 100 after cutting by using a fixed method, improving the overall processing efficiency of the motor aluminum shell.

[0051] Moreover, when the grinding of the cutting surface of the motor aluminum shell is completed, considering that during the subsequent processing of the motor aluminum shell, its inner wall also needs to be polished for subsequent spraying processing and the like. Therefore, after the grinding of the cutting surface is completed, control the energy storage electric push rod IV 201 on the arc-shaped support plate 116 to drive the grinding roller 202 to move out of the through groove 11604. Then, control the energy storage electric push rod II 117 to drive the arc-shaped support plate 116 to move closer to the inner wall of the motor aluminum shell, so that the grinding roller 202 contacts the inner wall of the motor aluminum shell. Then, control the AC motor 112 to drive the arc-shaped support plate 116 and the grinding roller 202 to rotate, and polish and grind the inner wall of the motor aluminum shell through the grinding roller 202, thereby reducing the subsequent grinding process of the motor aluminum shell and improving the overall processing efficiency. Moreover, there are several suction ports 11603 on the arc-shaped support plate 116. When the grinding roller 202 is working, the suction ports 11603 can suck away the debris generated by its grinding, preventing the debris from accumulating on the surface of the arc-shaped support plate 116 and affecting its subsequent support effect. After completion, then control the push plate 136 to move to push down the ground motor aluminum shell, and then repeat the above operations for subsequent cutting and grinding.

[0052] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form. Any technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
