[0029] like Figure 2-Figure 4 As shown, a fixed column 115 is fixedly installed on the base frame 101, a clamping block 113 is slidably installed on the fixed column 115, a clamping rod 114 is fixedly installed on the clamping block 113, an unlocking slider 117 is slidably installed on the base frame 101, the unlocking slider 117 is fixedly installed with the clamping rod 114, an unlocking rotating rod 116 is rotatably installed on the unlocking slider 117, and the unlocking rotating rod 116 is rotatably installed with the sliding frame 104.

[0030] When the electric cylinder 103 is not extended, the block 113 blocks the card wheel 107. At this time, the card wheel 107, the connecting shaft 106, the slide groove cylinder 108, the rotating disk 109 and the end rotating column 118 cannot rotate. When the electric cylinder 103 is extended, it drives the sliding frame 104 to slide along the base frame 101, the slide spring 105 is compressed, and the sliding frame 104 drives the unlocking rotating rod 116 to rotate, thereby driving the unlocking slider 117 and the clamping rod 114 to slide upward, thereby driving the block 113 to slide upward, so that the block 113 is disengaged from the card wheel 107, and the card wheel 107 is released from the restriction. At the same time, the sliding frame 104 slides, driving the push plate 110, the slide rod 111 and the pushing frame 112 to slide along the slide groove cylinder 108 and the end rotating column 118.

[0031] like Figure 5-Figure 7 As shown, the internal positioning mechanism includes a plurality of push blocks 202 slidably mounted on the end rotating column 118, the push blocks 202 are in contact with the pushing frame 112, a push rotating rod 203 is rotatably mounted on the push blocks 202, a roller 204 is rotatably mounted on the push rotating rod 203, a torsion spring is arranged between the push rotating rod 203 and the roller 204, and the roller 204 is in contact with the inner support turntable 201.

[0032] like Figure 5-Figure 7 As shown, a plurality of inner support columns 208 are slidably installed in the inner support turntable 201, an inner support block 209 is fixedly installed on the inner support column 208, a plurality of push-up blocks 205 are slidably installed in the inner support turntable 201, a push-up column 206 is fixedly installed on the push-up block 205, a push-up spring 207 is arranged between the inner support column 208 and the push-up block 205, and the push-up block 205 is in contact with the roller 204.

[0033] like Figure 5-Figure 7As shown, an inner slider 210 is slidably installed in the inner support column 208 , two inner rotating rods 211 are rotatably installed on the inner slider 210 , and an extension slider 212 is rotatably installed on the inner rotating rods 211 , and the extension slider 212 slides along the inner support block 209 .

[0034] When in use, the bearing sleeve is placed on the outside of the pull rod 301. When the pushing frame 112 moves outward, it pushes the pushing block 202 back to slide along the end rotating column 118, thereby driving the pushing rotating rod 203 to rotate, thereby driving the pushing block 205, the pushing column 206 and the pushing spring 207 to move outward through the roller 204. First, the pushing spring 207 drives the inner support column 208 and the inner support block 209 to move outward, so that the inner support block 209 contacts the inner ring of the bearing and tightens the inner ring of the bearing. Then the pushing block 205 continues to rise, the pushing spring 207 is compressed, and the pushing column 206 contacts the inner slider 210, driving the inner slider 210 to slide relative to the inner support column 208, thereby driving the inner rotating rod 211 to rotate, thereby driving the extension slider 212 to slide outward relative to the inner support block 209, and increasing the support area for the inner ring of the bearing through the extension slider 212.

[0035] like Figure 8 , Fig. 9 As shown, the external support mechanism includes three sliding blocks 302 slidably mounted on the rotating disk 109, the sliding blocks 302 are rotatably mounted with the pull rod 301, and a lower pull rod 303 is rotatably mounted on the sliding blocks 302. Three lower pressure frames 304 are slidably mounted on the rotating disk 109, and a lower pressure column 305 is fixedly mounted on the lower pressure frame 304. The lower pressure frame 304 and the lower pull rod 303 are rotatably mounted. Two opening frames 306 are rotatably mounted on the lower pressure column 305, and a rotating ring 308 is rotatably mounted on the opening frame 306. An opening spring 307 is arranged between the two rotating rings 308, an external pressure roller 309 is rotatably mounted on the opening frame 306, and a protruding block 310 is arranged below the lower pressure column 305.

[0036] When the pushing frame 112 slides outward, it drives the pull rod 301 to rotate, thereby driving the sliding block 302 to descend, thereby pulling the lower pressure frame 304 and the lower pressure column 305 down by pulling the lower rotating rod 303, so that the external pressure roller 309 contacts the outer ring of the bearing. As the lower pressure column 305 continues to descend, the opening frame 306 and the lower pressure column 305 rotate relative to each other, the opening spring 307 is stretched, the external pressure roller 309 is tightly attached to the outer ring of the bearing, and finally the raised block 310 contacts and clamps the outer ring of the bearing. When the inner and outer rings of the bearing are supported, the motor 102 rotates to drive the clamping wheel 107, the connecting shaft 106, the slide groove cylinder 108, the rotating disk 109, the end rotating column 118 and the inner support rotating disk 201 to rotate, which can drive the bearing to rotate to perform various processing.

[0037] The working principle of a bearing positioning processing device disclosed in the present invention is as follows: when in use, the bearing is sleeved on the outside of the pull rod 301, and when the electric cylinder 103 is not extended, the clamping block 113 clamps the clamping wheel 107. At this time, the clamping wheel 107, the connecting shaft 106, the slide groove cylinder 108, the rotating disk 109 and the end rotating column 118 cannot rotate. When the electric cylinder 103 is extended, the sliding frame 104 is driven to slide along the base frame 101, and the sliding frame spring 105 is compressed. The sliding frame 104 drives the unlocking rotating rod 116 to rotate, thereby driving the unlocking slider 117 and the clamping rod 114 to slide upward, thereby driving the clamping block 113 to slide upward, so that the clamping block 113 is disengaged from the clamping wheel 107, and the clamping wheel 107 is released from the restriction. At the same time, the sliding frame 104 slides, driving the pushing disk 110, the sliding rod 111 and the pushing frame 112 to slide along the slide groove cylinder 108 and the end rotating column 118. When the pushing frame 112 moves outward, it pushes the pushing block 202 back to slide along the end rotating column 118, thereby driving the pushing rotating rod 203 to rotate, thereby driving the pushing block 205, the pushing column 206 and the pushing spring 207 to move outward through the roller 204, firstly driving the inner support column 208 and the inner support block 209 to move outward through the pushing spring 207, so that the inner support block 209 contacts the inner ring of the bearing and tightens the inner ring of the bearing, then the pushing block 205 continues to rise, the pushing spring 207 is compressed, and after the pushing column 206 contacts the inner slider 210, it drives the inner slider 210 to slide relative to the inner support column 208, thereby driving the inner rotating rod 211 to rotate, thereby driving the extension slider 212 to slide outward relative to the inner support block 209, and increasing the support area for the inner ring of the bearing through the extension slider 212. When the pushing frame 112 slides outward, it drives the pull rod 301 to rotate, thereby driving the sliding block 302 to descend, thereby pulling the lower pressure frame 304 and the lower pressure column 305 down by pulling the lower rotating rod 303, so that the external pressure roller 309 contacts the outer ring of the bearing. As the lower pressure column 305 continues to descend, the opening frame 306 and the lower pressure column 305 rotate relative to each other, the opening spring 307 is stretched, the external pressure roller 309 is tightly attached to the outer ring of the bearing, and finally the raised block 310 contacts and clamps the outer ring of the bearing. When the inner and outer rings of the bearing are supported, the motor 102 rotates to drive the clamping wheel 107, the connecting shaft 106, the slide groove cylinder 108, the rotating disk 109, the end rotating column 118 and the inner support rotating disk 201 to rotate, which can drive the bearing to rotate to perform various processing.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope of the present invention, which should be covered by the protection scope of the present invention.
