[0031] like Figure 1-Figure 4 As shown, some embodiments of the present application provide a bearing support processing fixture, including a base plate 1, and a positioning shaft 2, a clamping assembly 3 and a limiting assembly 4 installed on the base plate 1. Among them, the clamping assembly 3 includes a clamping block 31, and the limiting assembly 4 includes a limiting member 41.
[0032] When the bearing support 5 to be processed needs to be processed, the bearing support 5 is placed on the base plate 1 and sleeved on the positioning shaft 2. Subsequently, the pressing member is pressed on the upper surface of the bearing support 5 to press the bearing support 5 on the base plate 1 to prevent the bearing support 5 from shaking under the cutting force of the processing tool during the processing. Finally, the limiting member 41 is pressed against the side wall of the bearing support 5 to prevent the bearing support 5 from rotating relative to the processing tool under the cutting force of the processing tool during the processing, which is conducive to ensuring the processing quality of the bearing support 5.
[0033] It should be noted that the side wall of the bearing support 5 is partially configured as a plane, and the limiting member 41 abuts against the plane side wall.
[0034] When the machining tool cuts the end face of the bearing support 5, it cuts in the same direction, and no cutting action is performed when the machining tool is retracted. Therefore, the present application only sets one set of limit components 4 to achieve the purpose of preventing the bearing support 5 from rotating relative to the machining tool during the machining process. When the machining tool cuts the end face of the bearing support 5 in a clockwise direction along the circumference of the bearing support 5, the limit component 4 is set on the right side of the bottom plate 1; otherwise, the limit component 4 is set on the left side of the bottom plate 1.
[0035] Exemplarily, the circumferential side walls of the positioning shaft 2 have relatively arranged cutting planes, which reduce the surface area of the positioning shaft 2 in contact with the inner ring of the bearing support 5, which is beneficial to reducing the machining accuracy of the positioning shaft 2 and saving machining costs.
[0036] It should be noted that the base plate 1 is provided with a mounting hole for connecting with a processing machine tool.
[0037] In some embodiments, the limiting assembly 4 further includes a connection seat 42 mounted on the bottom plate 1, and the limiting member 41 is connected to the connection seat 42. Moreover, the limiting member 41 can move relative to the connection seat 42, so that the limiting member 41 can be close to or away from the bearing support 5. When the model of the bearing support 5 is changed, since the outer dimensions of the bearing support 5 change, the relative position between the limiting member 41 and the connection seat 42 can be adjusted to adapt to different models of bearing supports 5, which is conducive to improving the versatility of the present application.
[0038] Exemplarily, in order to reduce costs, the limiting member 41 can be set as a screw, and a threaded hole matching the screw is provided on the connecting seat 42. The limiting member 41 can be moved relative to the connecting seat 42 by rotating the screw.
[0039] In some embodiments, the limiting assembly 4 further includes a second fastener 43 connected to the limiting member 41 , so as to fix the limiting member 41 on the connecting seat 42 , so as to achieve the purpose of limiting the rotation of the bearing support 5 .
[0040] For example, when the stopper 41 is a screw, the second fastener 43 can be a nut to prevent the screw from loosening under the cutting force of the machining tool. The second fastener 43 can be provided with one or two, respectively located on both sides of the connecting seat 42.
[0041] In some embodiments, in order to further improve the flatness of the machined end surface of the bearing support 5 and the parallelism between the two machined end surfaces, a first support column 6 is installed on the bottom plate 1, and the lower surface of the bearing support 5 abuts against the first support column 6, so that the bearing support 5 is supported on the bottom plate 1 through the first support column 6. Such a setting can reduce the contact area between the bearing support 5 and the support surface, and avoid machining errors caused by insufficient surface accuracy of the support surface when machining the end surface of the bearing support 5.
[0042] Specifically, more than three first support columns 6 are provided, and the number of first support columns 6 can be 3, 4, 5, 6, etc., according to actual needs. In this embodiment, the number of first support columns 6 is set to 6. Moreover, the plurality of first support columns 6 are distributed along the circumference of the positioning shaft 2 to support the bearing support 5.
[0043] It should be noted that after the first support columns 6 are installed on the base plate 1, it is necessary to use a processing tool to cut the upper surfaces of all the first support columns 6, that is, the support surface of the first support columns 6 relative to the bearing support 5, to ensure that the upper surfaces of all the first support columns 6 are on the same plane, thereby ensuring the flatness of the processed end surface of the bearing support 5 and the parallelism between the two processed end surfaces.
[0044] Exemplarily, the first support column 6 is configured as a cylindrical structure, and a through stepped hole is provided in the middle of the cylindrical structure, and the stepped hole is used to cooperate with a screw to install the first support column 6 on the base plate 1.
[0045] In some embodiments, more than two clamping assemblies 3 are provided, and the number of clamping assemblies 3 is provided as 2, 3, 4, etc. In this embodiment, the number of clamping assemblies 3 is provided as 3. Moreover, the plurality of clamping assemblies 3 are distributed along the circumference of the positioning shaft 2 to press the bearing support 5 onto the base plate 1 or the first support column 6.
[0046] In some embodiments, the clamping assembly 3 further includes a second support column 32, an adjustment column 33 and a first fastener 34, and the second support column 32 and the adjustment column 33 are both mounted on the base plate 1. The upper end of the second support column 32 is rotatably connected with a clamping block 31. Moreover, a through adjustment groove 311 is provided on the clamping block 31, and the adjustment column 33 runs through the adjustment groove 311. The first fastener 34 is movably mounted on the adjustment column 33 and is pressed on the clamping block 31, so that the clamping block 31 is pressed on the bearing support 5.
[0047] It should be noted that the pressing block 31 is pressed on the non-machined surface of the bearing support 5 .
[0048] Exemplarily, one end of the pressing block 31 pressing the bearing support 5 is provided with a yielding portion 312. The yielding portion 312 is provided as an inclined surface with an inclined angle, so that the thickness and width of one end of the pressing block 31 pressing the bearing support 5 become thinner, which is conducive to yielding the machining tool.
[0049] Specifically, the first fastener 34 can move up and down relative to the adjusting column 33, thereby adjusting the clamping force applied by the clamping block 31 to the bearing support 5, so that the clamping block 31 is pressed on the upper surface of the bearing support 5 to prevent the bearing support 5 from shaking or rotating under the cutting force of the machining tool.
[0050] For example, in order to reduce costs, the adjustment column 33 may be provided as a stud, and the first fastener 34 may be provided as a nut matched with the stud.
[0051] In some embodiments, a limit pin 321 is provided at the upper end of the second support column 32, and a clearance groove 313 cooperating with the limit pin 321 is provided on one side of the clamping block 31 located on the second support column 32, so that the clamping block 31 can rotate relative to the second support column 32, thereby adjusting the relative position of the clamping block 31 and the bearing support 5 to avoid interference between the clamping block 31 and the processing tool.
[0052] Specifically, the adjusting column 33 is clearance-matched with the adjusting groove 311 , and the adjusting groove 311 and the giving way groove 313 are both configured as long strip structures, so as to further adjust the relative position of the clamping block 31 and the bearing support 5 to avoid interference between the clamping block 31 and the machining tool.
[0053] To summarize, the utility model provides a bearing support processing fixture, which arranges a positioning shaft, a clamping assembly and a limit assembly on a base plate. When the bearing support to be processed needs to be processed, the bearing support is sleeved on the positioning shaft, and then the clamping block of the clamping assembly presses the bearing support onto the base plate to prevent the bearing support from shaking during the processing. Finally, the limit piece of the limit assembly presses against the side wall of the bearing support to prevent the bearing support from rotating during the processing, which is beneficial to ensuring the processing quality of the bearing support. The structure is simple, which is convenient for the assembly and disassembly of the bearing support.
