[0032] Referring to Figure 1 , an embodiment provided by the present utility model: A two-way chamfering device for bearings includes a base 1, which plays a supporting and fixing role for the support frame 2. A support frame 2 is fixedly connected to the top of the base 1. Guide grooves are provided on the top of the base 1, and two groups of guide grooves are symmetrically distributed. The guide grooves play a guiding role for the moving column 4 to prevent the moving column 4 from shifting during movement. The inner wall of the guide groove is slidably connected to the moving column 4, and two groups of moving columns 4 are symmetrically distributed. Through the sliding effect of the moving column 4, the chamfering tool 6 can be driven to chamfer the bearing. The bottom end of the inner wall of the support frame 2 is fixedly connected with electric push rods 3, and two groups of electric push rods 3 are symmetrically distributed. The left top end of the moving column 4 is fixedly connected with a motor 5, and two groups of motors 5 are symmetrically distributed. The moving column 4 plays a supporting and fixing role for the motor 5. The output shaft of the motor 5 can be installed and disassembled with a chamfering tool 6 through a mounting and dismounting component 8. Through the mounting and dismounting component 8, it is convenient to replace the chamfering tool 6. Two groups of chamfering tools 6 are symmetrically distributed. Through the rotating effect of the chamfering tool 6, the bearing is chamfered. A clamping component 7 is arranged on the top of the base 1. Through the clamping component 7, it is convenient to clamp and fix bearings of different sizes.

[0033] Referring to Figure 1 and Figure 2 , the clamping component 7 includes a fixed ring 71, and the outer wall of the fixed ring 71 is rotatably connected to a rotating ring 72. Through the rotating effect of the rotating ring 72, four hinge rods 75 are simultaneously driven to move. The right side of the rotating ring 72 is hinged with a hinge rod 75, and four groups of hinge rods 75 are annularly arranged. Through the moving effect of the hinge rod 75, the cylindrical rod 73 is driven to move. The top end of the hinge rod 75 is hinged with a cylindrical rod 73, and four groups of cylindrical rods 73 are annularly arranged. The bottom end of the cylindrical rod 73 is fixedly connected with a clamping plate 74, and four groups of clamping plates 74 are annularly arranged. And a rubber pad is arranged on the clamping surface of the clamping plate 74. Through the four clamping plates 74, the periphery of the bearing can be clamped and fixed. Support columns 76 are fixedly connected to both the upper and lower ends of the fixed ring 71.

[0034] Referring to Figure 1 and Figure 3, the disassembly and assembly component 8 includes mounting blocks 81, and there are two sets of symmetrically distributed mounting blocks 81. Through the rotation effect of the mounting blocks 81, the housing 83 is driven to rotate. The outer wall of the mounting block 81 is inserted with the housing 83. By inserting the housing 83 into the mounting block 81, the fixing block 84 can slide along the inner wall of the chute 82. The outer wall of the mounting block 81 is provided with chutes 82. The chutes 82 are L-shaped and there are two sets. The inner wall of the housing 83 is fixedly connected with fixing blocks 84. There are two sets of symmetrically distributed fixing blocks 84. The two sets of fixing blocks 84 correspond to the two sets of chutes 82. The inner front wall of the mounting block 81 is elastically connected with a wedge block 85 through a limiting spring 86. Through the elastic force of the limiting spring 86, the wedge block 85 always maintains the clamping effect with the card slot without external force, so as to limit the housing 83. The front of the housing 83 is provided with a card slot.

[0035] Refer to Figure 1 and Figure 2 , the output end of the electric push rod 3 is fixedly connected to the left side of the moving column 4. By starting the electric push rod 3, the moving column 4 can be driven to slide along the inner wall of the guiding groove. There are two sets of supporting columns 76. The top of one set of supporting columns 76 is fixedly connected to the top inner wall of the support frame 2, and the bottom of the other set of supporting columns 76 is fixedly connected to the top of the base 1. By providing two sets of supporting columns 76, the fixing ring 71 is stably supported and fixed.

Through the sliding effect of the cylindrical rod 73, the clamping plate 74 is driven to move, so that the clamping plate 74 approaches or moves away from the center of the fixing ring 71.

[0036] Refer to Figure 2 and Figure 4 , the left side of the rotating ring 72 is fixedly connected with a cylindrical barrel 77. Through the fixing effect of the cylindrical barrel 77, the cylindrical barrel 77 is prevented from falling off. The inner wall of the cylindrical barrel 77 is elastically connected with a clamping block 78 through a spring 79. Through the elastic force of the spring 79, the clamping block 78 always maintains the clamping effect with the round hole without external force, so as to limit the cylindrical barrel 77 and keep the rotating ring 72 fixed. The front left end of the fixing ring 71 is fixedly connected with a fixing plate 711. Through the fixing effect of the fixing plate 711, the fixing plate 711 is prevented from falling off. The right side of the fixing plate 711 is provided with round holes, and there are multiple sets of round holes. Through the clamping effect of the multiple sets of round holes and the clamping block 78 at different positions, the cylindrical barrel 77 is limited at different positions.

[0037] Refer to Figure 1 and Figure 3, the left side of the mounting block 81 is fixedly connected to the output shaft of the motor 5. By starting the motor 5, the mounting block 81 can be driven to rotate. The right side of the housing 83 is fixedly connected to the left end of the chamfering tool 6. Through the rotation effect of the housing 83, the chamfering tool 6 can be driven to rotate. The outer wall of the fixing block 84 is slidably connected to the inner wall of the chute 82. Through the sliding effect of the fixing block 84, the housing 83 and the mounting block 81 are inserted or disengaged. One end of the limiting spring 86 is fixedly connected to the inner wall of the front surface of the mounting block 81, and the other end of the limiting spring 86 is fixedly connected to the outer wall of the wedge block 85. Through the fixing effect of the limiting spring 86, the wedge block 85 is kept fixed to prevent the wedge block 85 from falling off. The outer wall of the wedge block 85 is slidably connected to the inner wall of the front surface of the mounting block 81. Through the sliding effect of the wedge block 85, the wedge block 85 is engaged or disengaged with the card slot. The outer wall of the wedge block 85 is engaged with the inner wall of the card slot. Through the engagement effect of the wedge block 85 and the card slot, the mounting block 81 limits the housing 83.

[0038] Refer to Figure 4 , a handle 710 is fixedly connected to the front surface of the cylindrical barrel 77. Through the handle 710, it is convenient for the staff to move the cylindrical barrel 77. One end of the spring 79 is fixedly connected to the inner wall of the cylindrical barrel 77, and the other end of the spring 79 is fixedly connected to the outer wall of the clamping block 78. Through the fixing effect of the spring 79, the clamping block 78 is kept fixed to prevent the clamping block 78 from falling off. The outer wall of the clamping block 78 is slidably connected to the inner wall of the cylindrical barrel 77. Through the sliding effect of the clamping block 78, the clamping block 78 is engaged or disengaged with the round hole. The outer wall of the clamping block 78 is engaged with the inner wall of the round hole. Through the engagement effect of the clamping block 78 and the round hole, the fixing plate 711 limits the cylindrical barrel 77.

[0039] Working principle: When the staff needs to chamfer the bearing, the housing 83 on the chamfering tool 6 is inserted into and then rotated with the mounting block 81 by the staff, so that the fixing block 84 slides along the inner wall of the chute 82. When the card slot opened on the housing 83 corresponds to the wedge block 85, the wedge block 85 will be engaged with the card slot under the elastic force of the limiting spring 86, and at the same time, the housing 83 is limited, so that the housing 83 is fixedly installed on the mounting block 81, and at the same time, the installation of the chamfering tool 6 is completed.

[0040] Subsequently, the staff places the bearing inside the fixed ring 71, presses the clamping block 78, so that the clamping block 78 releases the clamping effect with the circular hole, and at the same time releases the limiting effect on the cylindrical barrel 77. The staff uses the handle 710 to move the cylindrical barrel 77, drives the rotating ring 72 to rotate through the cylindrical barrel 77, drives the four hinge rods 75 to move through the cylindrical barrel 77 at the same time, drives the four cylindrical rods 73 to slide through the four hinge rods 75 at the same time, and drives the four clamping plates 74 to move through the four cylindrical rods 73, so that the four clamping plates 74 clamp and fix the bearing inside the fixed ring 71. When the bearing is clamped and fixed, release the clamping block 78, so that the clamping block 78 is clamped with the circular hole under the elastic force of the spring 79, thereby limiting the cylindrical barrel 77 and keeping the rotating ring 72 fixed, so that the four clamping plates 74 maintain a fixed clamping state.

[0041] Subsequently, the staff starts the electric push rod 3 and the motor 5. The electric push rod 3 drives the moving column 4 to slide towards the bearing, thereby driving the chamfering tool 6 to slide towards the bearing. The motor 5 drives the mounting block 81 to rotate, so that the housing 83 and the chamfering tool 6 rotate, so as to chamfer both sides of the bearing. When the chamfering tool 6 needs to be replaced and maintained, the staff presses the wedge block 85, so that the wedge block 85 releases the clamping effect with the card slot, and at the same time releases the limiting effect on the housing 83. Rotate the housing 83 in the reverse direction to release the plug-in effect with the mounting block 81, so as to facilitate the removal of the chamfering tool 6 and the housing 83, and facilitate the maintenance and replacement of the chamfering tool 6.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
