Detailed description of the invention
Referring to figs. 1 through Fig. 2, a kind of Curved shaft support device of the utility model is described further.
As shown in Figure 1, a kind of structural representation of Curved shaft support device, the utility model comprises the supporting seat 2 for supporting bent axle 3, it is a brace table 1 below supporting seat 2, brace table 1 is conducive to staff and places bent axle 3 cubing or other instruments, supporting seat 2 comprises the first pedestal 21 and the second pedestal 22 of two different structures, top is the left side that the first pedestal 21 of V-type shape is fixed on brace table 1, second pedestal 22 is fixed on the right side of brace table 1, and bent axle 3 is set up between the first pedestal 21 and the second pedestal 22.Bent axle 3 left end is placed in the V-type portion of the first pedestal 21, second pedestal 22 is connected with a column type protective cover 8 and one for drawing the lifting framework that bent axle 3 moves up and down, lifting mechanism comprises a drive disk assembly 4 and an one-way driving mechanism 5, drive disk assembly 4 is rotationally connected with one-way driving mechanism 5, wherein drive disk assembly 4 comprises the connecting element 41 and tooth bar 42 that are connected, connecting element 41 can be a three-jaw chuck, and the chuck body of three-jaw chuck is positioned at the left side of protective cover 8.As shown in Figure 2, tooth bar 42 is positioned at protective cover 8.Preferably, offer passage at the left end of protective cover 8, three-jaw chuck right-hand member is fixed with contiguous block, and contiguous block to wear in protective cover 8 and is connected with tooth bar 42.One-way driving mechanism 5 can be a worm gear 52 and worm screw 51, worm gear 52 is in being vertically arranged in protective cover 8, and below is meshed with worm screw 51, and left side is meshed with tooth bar 42, the right-hand member of worm screw 51 is fixedly connected with a drive spindle 6, and drive spindle 6 wears protective cover 8 right side and connects a handwheel 7.Connecting element 41 of the present utility model can play bent axle 3 and prevent shaking amplitude excessive at lifting process, and is fixed by bent axle 3 completely after height adjusted by bent axle 3, prevents the occurrence positions skew when detecting the hole site on bent axle 3 flange.
Another kind of embodiment of the present utility model, two helical wheels be meshed that are vertical setting, a screw rod is fixedly connected with in the middle part of helical wheel wherein, screw flight connects a sleeve, sleeve is fixed in three-jaw chuck, the helical wheel right side central of right connects drive spindle 6, drive spindle 6 wears protective cover 8 right side and connects handwheel 7, when rotation hand rotates making below helical wheel, bolt rotary is tightened in sleeve, the relative screw rod of sleeve declines, indirectly decline with three-jaw chuck, rotate backward hand to rotate backward making below helical wheel, screw rod produces in sleeve, the relative screw rod of sleeve rises, indirectly rise with three-jaw chuck.
Before the utility model bent axle 3 upper flange hole site is detected, bent axle 3 sets up on bracing or strutting arrangement and is elevated bent axle 3, dial measuring gauge is used first to carry out parallelism adjustment to bent axle 3, concrete operating mode is, before staff uses minitype travelling crane to transport bent axle 3 to brace table 1, bent axle 3 one end is erected on the first pedestal 21, the other end sets up in the groove of three-jaw chuck on the second pedestal 22, height about the surface measurement of use dial measuring gauge contact conflict bent axle 3, if right-hand member is lower than left end, applying slight pulls handwheel 7 makes worm screw toward moving left, worm gear 52 rotational synchronization band carry-over bar 42 is driven to rise, bent axle 3 right-hand member rises, because worm gear 52 can not turn round on worm screw, make bent axle 3 can be stabilized in certain height not decline, at use dial measuring gauge, hole site on shaft flange is measured, otherwise when right-hand member makes worm screw 51 toward moving right higher than rotating handwheel 7 during left end, bent axle 3 declines with three-jaw chuck.
Protection domain of the present utility model be not only confined to above-described embodiment, all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
