Example 1: a screw mandrel rocking handle is shown in figure 1 and comprises an L-shaped hollow mounting block 1 with openings at two ends and a steering mechanism 2 (shown in figure 2) arranged in the mounting block 1, wherein two sections of the mounting block 1 which are vertical to each other are equal in length, and the steering mechanism 2 comprises a driving rotating shaft 21 and a driven rotating shaft 23 which are rotationally connected with the mounting block 1. One end of the driven rotating shaft 23 is arranged in the inner cavity of the mounting block 1 and is coaxially sleeved with a driven gear 24, and the driven gear 24 and the driven rotating shaft 23 synchronously rotate through a flat key. The other end of the driven rotating shaft 23 extends out of the opening of the mounting block 1 and can be coaxially connected with the screw rod. One end of the driving rotating shaft 21 is also arranged in the inner cavity of the mounting block 1, a driving gear 22 is coaxially sleeved at one end of the driving rotating shaft located in the inner cavity of the mounting block 1, the driving gear 22 rotates synchronously with the driving rotating shaft 21 through a flat key, and the driven gear 24 can be meshed with the driving gear 22. The one end that driving gear 22 was kept away from to initiative pivot 21 stretches out from the one end that driven shaft 23 was kept away from to installation piece 1, can be when the amesdial reading this moment, thereby drive driven shaft 23 through rotating initiative pivot 21 and rotate, and then realize the rotation of lead screw, only need a workman just can realize the number of degrees and the rotation of drive lead screw to the amesdial, thereby required labour when having reduced the axis of main shaft and the depth of parallelism of guide rail and detecting, it is more convenient to make the depth of parallelism of main shaft detect.
As shown in fig. 3, when the screw rod is driven to rotate by the driven rotating shaft 23, the screw rod and the driven rotating shaft 23 need to be rotated synchronously, and after the parallelism detection of the main shaft is completed, the driven rotating shaft 23 needs to be separated from the screw rod. Therefore, the end of the driven rotating shaft 23 far away from the driven gear 24 is coaxially connected with the connecting sleeve 25, the end surface of the connecting sleeve 25 coaxially penetrates through the connecting groove 251, and the driven rotating shaft 23 can be inserted into the connecting groove 251. The connecting sleeve 25 is connected with a mounting bolt 26 for connecting the connecting sleeve with the driven rotating shaft 23, the mounting bolt 26 penetrates through the connecting sleeve 25 and the driven rotating shaft 23, and the screw rod of the mounting bolt is in threaded connection with the connecting sleeve 25 at a position far away from the nut. A connecting bolt 27 penetrates through the side wall of the connecting sleeve 25 at a position far away from the mounting bolt 26, and a screw rod of the connecting bolt 27 penetrates through the outer wall of the connecting sleeve 25 to be arranged in the inner cavity of the connecting sleeve 25 and is in threaded connection with the connecting sleeve 25. One end of the screw rod dismounting handle can be inserted into the connecting groove 251, and one end of the screw rod of the connecting bolt 27, which is far away from the nut, is abutted against the side wall of the screw rod. The connecting bolt 27 is utilized to fix the position of the screw rod connecting sleeve 25, so that the screw rod can synchronously rotate along with the rotation of the driven rotating shaft 23, and meanwhile, the connecting sleeve 25 and the screw rod are more quickly installed and detached, and the use process of the screw rod rocking handle is more convenient.
As shown in fig. 2, when the driving shaft 21 is rotated to drive the driven shaft 23 to rotate, the relative positions of the driving shaft 21 and the driven shaft 23 need to be fixed, otherwise, the driving gear 22 cannot be meshed with the driven gear 24. Therefore, the driving rotating shaft 21 and the driven rotating shaft 23 are both connected with a limiting mechanism 3 for limiting the positions of the driving rotating shaft and the driven rotating shaft, and the limiting mechanism 3 comprises a cylindrical limiting block 31 which is connected with the mounting block 1 and is arranged in a hollow mode, and two ends of the cylindrical limiting block 31 are open, and two bearings 32 connected with the limiting block 31. The outer wall of the limiting block 31 is coaxially provided with a clamping groove 311, and one end of the limiting block 31 is penetrated through the clamping groove 311. The stopper 31 can be inserted in the installation block 1, and the side wall of the clamping groove 311 close to the axis of the stopper 31 can be abutted against the inner wall of the installation block 1, and the end face of the clamping groove 311 which is not opened is fixed with the end face of the installation block 1 by using a bolt. The two bearings 32 are arranged in the inner cavity of the limiting block 31, the outer wall of the outer ring of the bearing is abutted against the inner wall of the limiting block 31, and the inner wall of the inner ring of the bearing is abutted against the side wall of the driving rotating shaft 21 or the driven rotating shaft 23. The position of the driving rotation shaft 21 and the driven rotation shaft 23 is limited by the limiting mechanism 3, so that the driving gear 22 can keep meshing with the driven gear 24, and the use of the steering mechanism 2 is kept stable.
As shown in fig. 2, when the steering mechanism 2 is used to drive the screw rod to rotate, the mounting block 1 needs to be fixed with the machine tool, so that the side wall of the limiting block 31 connected with the driven rotating shaft 23 is integrally formed with a connecting ring 33, two fastening bolts 34 penetrate through the end surface of the connecting ring 33 close to the connecting groove 251, and the two fastening bolts 34 penetrate through the connecting ring 33 and are in threaded connection with the support frame supporting the screw rod. When detecting the parallelism between the axis of the main shaft and the guide rail, the mounting block 1 is detached from and connected with a machine tool through the fastening bolt 34, so that the screw rod rocking handle is more convenient to use.
As shown in fig. 2, since different workers have different heights, in order to facilitate the rotation of the driving shaft 21, two circular arc-shaped waist-shaped grooves 331 are formed through the end surface of the connection ring 33, the circular arc axes of the waist-shaped grooves 331 are coincident with the axis of the connection ring 33, and the fastening bolts 34 respectively pass through the two waist-shaped grooves 331 and are arranged in the waist-shaped grooves 331 to slide. The position of the mounting block 1 can be adjusted by utilizing the waist-shaped groove 331, so that the height of one end of the driving rotating shaft 21, which is far away from the driving gear 22, can be adjusted, workers with different heights can more conveniently use the driving rotating shaft 21 to rotate, and the angle between the driving rotating shaft 21 and the horizontal plane can be adjusted under the condition of no need of repeated disassembly and assembly.
As shown in fig. 3, since the distance between the inner wall of the connecting sleeve 25 and the outer wall of the screw rod is small, in order to facilitate the process of inserting the screw rod into the connecting sleeve 25, a limiting groove 332 is coaxially formed in the end surface of the connecting ring 33 away from the mounting block 1, and the outer wall of the connecting ring 33 is penetrated through the limiting groove 332. When the connection ring 33 is connected to the machine tool, the inner wall of the limit groove 332 near the axis of the connection ring 33 may abut against the inner wall of the support frame. The position of the rotating mechanism is limited by the limiting groove 332, so that the axis of the connecting sleeve 25 can be kept coincident with the axis of the screw rod, the end face of the screw rod cannot be directly contacted with the end face of the connecting sleeve 25 when the screw rod is inserted into the connecting groove 251, and the process that the screw rod is inserted into the connecting groove 251 is more convenient.
As shown in fig. 3, since there is no point at which a force can be directly applied when the driving rotation shaft 21 is directly rotated, the rotation of the driving rotation shaft 21 is difficult. Therefore, the end of the driving shaft 21 far away from the driving gear 22 connected with the driving shaft is connected with the cross bar 11, and the end of the cross bar 11 far away from the driving shaft 21 is rotatably connected with the handle 12. The handle 12 is used to rotate the active shaft 21, and there is a point that can directly apply force during the rotation process, so that the rotation of the active shaft 21 is more convenient.
As shown in fig. 3, since the headstock has a large volume and the mounting block 1 has a short length, when the handle 12 is directly rotated, a worker needs to stretch the hand as much as possible to grasp the handle 12, and the detection process is troublesome. Therefore, the extension bar 13 is welded on the side wall of the cross bar 11 close to the active rotating shaft 21, and the extension bar 13 is sleeved on the active rotating shaft 21 and fixedly connected with the active rotating shaft through bolts. The handle 12 is positioned far away from the mounting block 1 through the extension rod 13, so that the handle 12 is closer to the position of the observation dial indicator where a worker is positioned, the worker can grasp the handle 12 more, the active rotating shaft 21 rotates, and the detection process is more convenient.
The working principle is as follows:
when the parallelism between the axis of the main shaft or the auxiliary shaft and the guide rail is detected, the handle connected with the screw rod of the main shaft box or the auxiliary shaft box is removed, then the connecting ring 33 is connected with the support frame, the side wall of the limit groove 332 is abutted against the inner wall of the support frame, the screw rod is inserted into the connecting sleeve 25, then the connecting bolt 27 is rotated to connect the connecting ring 33 with the support frame, and the height of the handle 12 is adjusted in the connecting process. The screw rod and the connecting sleeve 25 are kept fixed by rotating the fastening bolt, and the screw rod can be driven to rotate by rotating the handle 12, so that the parallelism detection is carried out.
Example 2: a main shaft parallelism detection method using a screw mandrel rocking handle comprises the following steps:
s1: disassembling, namely disassembling a handle of the screw rod connected with the main shaft or the auxiliary shaft to be detected;
s2: mounting, wherein the connecting ring 33 is abutted with the support frame connected with the screw rod, the limiting groove 332 is abutted with the inner wall of the support frame near the axis of the connecting ring 33 and the side wall, and meanwhile, one end of the screw rod is inserted into the connecting groove 251, then the fastening bolt is moved towards the threaded hole of the support frame for a distance, then the position of the connecting ring 33 is adjusted to enable one end of the extension rod far away from the mounting block 1 to incline upwards, then the fastening bolt is screwed with the support frame, and then the connecting bolt 27 is rotated to enable the screw rod of the connecting bolt to be abutted with;
s3: and detecting, namely attracting the magnetic base of the dial indicator with the upper end of the guide rail, enabling the measuring needle of the dial indicator to be abutted against the outer side wall of the main shaft and enabling the pointer of the dial indicator to rotate for ten scales, then rotating the handle 12 to enable the spindle box connected with the main shaft to move along the guide rail, and observing the reading change range of the dial indicator.
