Abstract
An I-shaped locking device is fixed on a side surface of a framework and comprises an I-shaped fixture. The I-shaped fixture is provided with a circular hole for mounting a transmission circular shaft and an adjusting groove communicated with the circular hole, and the circular hole is locked through a locking screw. The I-shaped locking device has the advantages that external force is acted in the transmission shaft by means of changing action points of the external force, and then work precision of a total precise measuring and detecting instrument can be guaranteed without affecting operation conditions of a ball screw assembly and a ball guide track surface. In addition, the I-shaped locking device is simple and reasonable in structure.
Description
Technical field
The utility model relates to a kind of yi word pattern locking device.
Background technology
In precision measurement, detecting instrument equipment, worktable is mounted on substantially on ball screw assembly, and the spherical guide face and moves, and when worktable need be done to stop detection in a certain working position, just worktable is fixed.Particularly the work top of plummet layout more should be fixed.And the work on hand platform is fixing, act on the worktable by external force often, again the suffered external force of worktable is delivered on high ball screw assembly, of accuracy requirement and the spherical guide face, can influence the kinematic accuracy of ball screw assembly, and spherical guide face like this, because the kinematic accuracy of ball screw assembly, and spherical guide, directly relevant with the precision and the tolerance clearance precision of its ball body, among external force is delivered to ball screw assembly, and spherical guide, its generation distortion in various degree will be made, the operating accuracy of precision measurement, detecting instrument equipment will be unfavorable for guaranteeing.
Summary of the invention
Existing act on worktable by external force and fix the defective that worktable can influence the kinematic accuracy of ball screw assembly, and spherical guide face for overcoming, the utility model provides a kind of yi word pattern locking device that does not influence the ruuning situation of ball screw assembly, and spherical guide face.
The technical solution of the utility model:
Yi word pattern locking device, it is fixed on the side of Rack Body, it is characterized in that: comprise the yi word pattern clamp body, have circular hole that the transmission circular shaft is installed and the adjustment groove that is communicated with circular hole on the described yi word pattern clamp body, described circular hole is locked by lock-screw.
Further, described yi word pattern clamp body has the destressing hole in the end of adjusting groove.
Further, have ladder light slotted eye on the described yi word pattern clamp body, described yi word pattern clamp body cooperates on the side that is fixed on Rack Body with ladder light slotted eye by sunk screw.
Ladder light slotted eye of the present utility model can make the yi word pattern clamp body do suitable moving; By regulating lock-screw, the circular hole size is changed.When screwing lock-screw, can make and adjust the groove size decreases, simultaneously, the circular hole size also diminishes; When unscrewing lock-screw, utilize the elastic deformation of material itself, make and adjust groove size restoration prototype, for this reason, the circular hole size also restPoses.
Principle of work of the present utility model: screw sunk screw the yi word pattern clamp body is fixed on the Rack Body, simultaneously the transmission circular shaft is inserted in the circular hole of yi word pattern clamp body, allow circular hole and circular shaft under the prerequisite of right alignment, make both keep certain clearance, in initial (not screwing lock-screw) state, the transmission circular shaft can not have frictional rotation in yi word pattern clamp body circular hole; In work (screwing lock-screw) state, the circular hole size also diminishes thereupon gradually, under the effect of friction force, make the circular hole surface chucking transmission circular shaft of yi word pattern clamp body, thereby transmission shaft can not rotate, thereby the ball screw assembly, that is connected on the transmission shaft can not be moved, reached the purpose of positioning and locking; When wanting travelling table, as long as unclamp lock-screw, under the effect of elastic deformation, the circular hole in the yi word pattern clamp body will return to initial position.Lead screw pair is rotated and the job requirement of locking thereby reach.
The beneficial effects of the utility model: by changing the application point of external force, external force is acted in the transmission shaft, no longer influence the ruuning situation of ball screw assembly, and spherical guide face, can guarantee the operating accuracy of whole precision measurement, detecting instrument equipment; And it is simple and reasonable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 be the utility model along A-A among Fig. 1 to cut-open view.
Fig. 3 be the utility model along B-B among Fig. 2 to cut-open view.
Embodiment
With reference to Fig. 1-3, yi word pattern locking device, it is fixed on the side of Rack Body 8, comprises yi word pattern clamp body 1, have circular hole 2 that transmission circular shaft 9 is installed and the adjustment groove 3 that is communicated with circular hole 2 on the described yi word pattern clamp body 1, described circular hole 2 is by lock-screw 5 lockings.
Described yi word pattern clamp body 1 has destressing 4 holes in the end of adjusting groove 3.
Have ladder light slotted eye 7 on the described yi word pattern clamp body 1, described yi word pattern clamp body 1 cooperates on the side that is fixed on Rack Body 8 with ladder light slotted eye 7 by sunk screw 6.
The utility model has two ladder light slotted eyes 7, and ladder light slotted eye 7 can make yi word pattern clamp body 1 do suitable moving; By regulating lock-screw 5, circular hole 2 sizes are changed.When screwing lock-screw 5, can make and adjust groove 3 size decreases, simultaneously, circular hole 2 sizes also diminish; When unscrewing lock-screw 5, utilize the elastic deformation of material itself, make and adjust groove 3 size restoration prototypes, for this reason, circular hole 2 sizes also restPose.
Principle of work of the present utility model: screw two sunk screws 6 yi word pattern clamp body 1 is fixed on the Rack Body 8, simultaneously transmission circular shaft 9 is inserted in the circular hole 2 of yi word pattern clamp body 1, allow circular hole 2 and circular shaft 9 under the prerequisite of right alignment, make both keep certain clearance, in initial (not screwing lock-screw 5) state, transmission circular shaft 9 can not have frictional rotation in the circular hole 2 of yi word pattern clamp body 1; In work (screwing lock-screw 5) state, circular hole 2 sizes also diminish thereupon gradually, under the effect of friction force, make the circular hole 2 surface chucking transmission circular shafts 9 of yi word pattern clamp body 1, thereby transmission circular shaft 9 can not rotate, thereby the ball screw assembly, that is connected on the transmission circular shaft 9 can not be moved, reached the purpose of positioning and locking; When wanting travelling table, as long as unclamp lock-screw 5, under the effect of elastic deformation, the circular hole 2 in the yi word pattern clamp body 1 will return to initial position.Lead screw pair is rotated and the job requirement of locking thereby reach.
The described content of this instructions embodiment only is enumerating the way of realization of utility model design; protection domain of the present utility model should not be regarded as only limiting to the concrete form that embodiment states, protection domain of the present utility model also reach in those skilled in the art according to the utility model design the equivalent technologies means that can expect.
