Specific implementation

[0028] As Figs. 1-4 Shown, a main shaft bearing spacer sleeve outer periphery runout detection device, comprising:

[0029] Detection table 101, the assembly plate 102 arranged on one side of the detection table 101, the mounting seat 103 arranged on the top of the detection table 101, the assembly plate 102 is vertically distributed on the horizontal plane relative to the mounting seat 103;

[0030] The mounting assembly is rotatably arranged on the top of the detection table 101, and comprises a rotating column 201 rotatably clamped on the detection table 101. A plurality of bearing blocks 202 are arranged on the top of the rotating column 201 in an array around the periphery. An installation groove 203 is arranged in the region between two opposite bearing blocks 202. A bidirectional screw rod 204 is rotatably arranged in the installation groove 203. A sliding block 205 is threadedly sleeved on each corresponding helical portion of the bidirectional screw rod 204. A vertical column 206 is arranged on the top of each sliding block 205. In use, the spacer sleeve 5 is placed on the bearing block 202, and the two vertical columns 206 are located in the inner hole of the spacer sleeve 5. Then, the two sliding blocks 205 are moved away from each other by rotating the bidirectional screw rod 204, so that the two vertical columns 206 are tightly pressed against the inner hole wall of the spacer sleeve 5, thereby stabilizing the spacer sleeve 5.

[0031] The visual detection piece is arranged on the mounting seat 103. The visual detection piece comprises a dial gauge 301 arranged on the mounting seat 103. The detection rod 302 of the dial gauge 301 abuts against the outer peripheral surface of the spacer sleeve 5. After the spacer sleeve 5 is assembled on the mounting assembly, the mounting assembly and the spacer sleeve 5 are rotated by actuating the bearing block 202. During the rotation of the spacer sleeve 5, the detection rod 302 of the dial gauge 301 moves on the outer peripheral surface of the spacer sleeve 5, thereby realizing the detection of the circular runout of the outer peripheral surface of the spacer sleeve 5. During the detection, the difference in the swing amplitude of the pointer on the dial gauge 301 can be observed, and the circular runout value of the outer peripheral surface of the spacer sleeve 5 can be obtained.

[0032] The recording detection piece is movably arranged on the assembly plate 102. The recording detection piece comprises a writing member and a display member. The writing member comprises a pointed head abutting rod 401 movably sleeved on the assembly plate 102. A convex disc 402 is arranged on the wall around the end of the pointed head abutting rod 401 close to the rotating column 201. A spring 403 is arranged on the rod body of the pointed head abutting rod 401 between the assembly plate 102 and the convex disc 402. The pointed head of the pointed head abutting rod 401 abuts against the outer peripheral surface of the spacer sleeve 5. The spring 403 arranged thereon can keep the pointed head of the pointed head abutting rod 401 in contact with the outer peripheral surface of the spacer sleeve 5. A writing pen 405 is clamped on the end of the pointed head abutting rod 401 away from the rotating column 201 by a clamping sleeve 404. The writing pen 405 arranged thereon can draw a meandering line during the rotation of the spacer sleeve 5.

[0033] The display member comprises a sliding frame 602 movably clamped on one side of the assembly plate 102 by a clamping groove 601. A writing board 603 is detachably clamped between the two horizontal clamping blocks of the sliding frame 602. The writing board 603 arranged thereon can be detached from between the two horizontal clamping blocks of the sliding frame 602 for replacement. The writing board 603 can record the meandering line drawn by the writing pen 405.

[0034] The linkage assembly is arranged between the mounting assembly and the record detecting member, and comprises a rotating shaft 701 and a rack 706. The rotating shaft 701 is arranged at the bottom of the detecting table 101 through a support 704. The rotating shaft 701 is provided with a bevel gear II 703 at one end. The bottom end of the rotating column 201 is provided with a bevel gear I 702 which is engaged with the bevel gear II 703. The other end of the rotating shaft 701 is provided with a gear 705. The vertical part of the sliding frame 602 is provided with the rack 706 which is engaged with the gear 705. When the spacer sleeve 5 rotates, the rotating column 201 also rotates synchronously. After the transmission of the bevel gear I 702 and the bevel gear II 703, the rotating shaft 701 can be driven to rotate. After the transmission of the gear 705 and the rack 706, the sliding frame 602 can be driven to move along the clamping groove 601 on the assembly plate 102, so as to drive the writing plate 603 to move.

[0035] The tip of the tip abutting rod 401 is always in abutting movement with the outer circumferential surface of the spacer sleeve 5 under the abutting of the spring 403. Therefore, during the movement of the tip of the tip abutting rod 401 on the outer circumferential surface of the spacer sleeve 5 for one circle, the tip abutting rod 401 can realize reciprocating movement on the assembly plate 102 due to the slight concave-convex part on the outer circumferential surface of the spacer sleeve 5. Then, in combination with the movement of the writing plate 603, the writing pen 405 can draw a zigzag line on the writing plate 603 during the movement of the tip of the tip abutting rod 401 on the outer circumferential surface of the spacer sleeve 5 for one circle. The difference between the maximum value and the minimum value of the zigzag line is the roundness value of the outer circumferential surface of the spacer sleeve 5. The writing plate 603 with the zigzag line can be saved for record, so as to be compared with the review data when subsequent review and analysis is needed.
