Abstract
The utility model discloses a positioning and locking device of a mobile screw rod support bearing. The device comprises a ball screw, wherein the ball screw is provided with a lock nut in thread fit with the ball screw; a supporting pedestal is sleeved at one end of the ball screw; and a bearing is arranged between the supporting pedestal and the ball screw. The device is characterized in that the lock nut is provided with a radial notch so that the cross section of the lock nut is C-shaped; a through hole is formed in one side provided with the radial notch in the lock nut; a thread hole is formed in the other side of the radial notch; and the ball screw is locked or unlocked by the lock nut by a fastener arranged on one side of the through hole. The device has large lock force and wide distributive area, and can endure variable impact carrying capacity caused by long-time back-and-forth reversing of the equipment.
Description
Technical field
The utility model relates to mobile screw mandrel spring bearing positioning and locking device.
Background technique
The PCVD equipment moving screw mandrel spring bearing locking device for preform processing using at present, its locking
The locking and positioning of nut be nut radially make a call to a M5 threaded perforations, by M5 lock screw, hold out against wire rod thread and realize locking.Which convenience quick for installation, but particularly band is impacted the operating mode of variable load for some operating mode, be subject to after variable impact load, fastening force bearing point distortion, be prone to loosening displacement, so that affect normal operation and the machining accuracy of equipment, thereby directly affect the quality of the chemical meteorology deposition in PCVD device fabrication process.
Model utility content
Technical problem to be solved in the utility model is to provide the large distribution of a kind of coupling mechanism force wide for the technical problem existing in above-mentioned prior art, and the long-time mobile screw mandrel spring bearing positioning and locking device that moves the variable impact load power that coming and going commutates brings of the equipment that can bear.
This novel adopted technological scheme is: mobile screw mandrel spring bearing positioning and locking device, it comprises ball screw, described ball screw is provided with the locking nut matching with its screw thread, one end at ball screw is set with supporting base, between supporting base and ball screw, be provided with bearing, it is characterized in that offering the cross section that radial indentation makes locking nut and be C type on locking nut, a side that is positioned at radial indentation on locking nut offers perforation, opposite side offers tapped hole, by the side in perforation, fastening piece being set makes locking nut by ball screw locking or unclamps.
By technique scheme, described perforation and tapped hole and vertical setting of the formed cleaved facet of radial indentation.
By technique scheme, between locking nut and supporting base, be provided with the collar, at the collar, be outside equipped with fixed cover and be fixedly connected with supporting base.
By technique scheme, on fastening piece, be equipped with spring washer.
By technique scheme, described fastening piece is hexagon socket head cap screw.
By technique scheme, described locking nut is outer-hexagonal nut.
The obtained beneficial effect of the utility model is:
1, the large distribution of this device coupling mechanism force is wide, and the long-time mobile round variable impact load power that commutates and bring of the equipment that can bear, thereby has guaranteed normal operation and the machining accuracy of equipment;
2, the maintenance of the equipment by practical this device also can correspondingly extend cycle time, thereby has guaranteed the output of the acceptable product of equipment.
