Description
Technical field
The utility model design is related to a kind of displacement detector, and worm-gear speed reducer is used for more particularly, to a kind of
The detection device of worm screw axial displacement.
Background technology
Speed reducer is a kind of relatively accurate machinery, and the purpose using it is to reduce rotating speed, increases torque.Speed reducer has
Many types, worm-gear speed reducer are one kind therein.Turbine worm reducer has the function of reverse self-locking, can have larger
Reduction ratio, but general volume is larger, and transmission efficiency is not high, and precision is not high.
Usual worm-gear speed reducer often clashes during long-term use, the worm and worm wheel of equipment
Generate many heats in collision when rotating each time, especially high-frequency and it is high with rate under conditions of these
Heat is even more very big, these heats can cause gap that can be increased；Secondly worm-gear speed reducer worm screw at work
It is also what can be in direct contact with one another in occurring with worm gear conflict, between them, particularly worm and worm wheel are when high-speed rotating
It waits, so can also generate gap for a long time.
Worm screw axial displacement can cause worm screw axial float in the course of work, all have an impact to worm gear and worm screw, such as too late
When adjust, can cause the damage of worm gear and worm screw, and then influence the service life of speed reducer.
Habitually in the past for gap there is no accurate detection device, the size that worm screw experiences gap typically is pushed to hand,
But generally when people experience gap there are when gap it is bigger, i.e., worm screw has had larger abrasion, therefore,
Often worm screw begins to wear out do not detect but already under such an approach.
The content of the invention
It is axial the purpose of this utility model is to provide a kind of worm-gear speed reducer worm screw for the deficiency of background technology
Displacement detector.
Technical solution is used by the utility model solves its technical problem：
Speed reducer is fixed in support platform in the utility model, and respectively there are one handwheel, leading screw and cunnings at the both ends of speed reducer
Block；Leading screw is fixed on by leading screw fixing piece on bearing diagonal platform, and leading screw is attached with handwheel using flat key, leading screw and sliding block
Coordinated using screw thread, leading screw rotates band movable slider and moves left and right；Mandril there are one being fixed on sliding block, mandril and speed reducer
Worm screw keeps concentric state；Connection firmware is installed, for connecting grating gauge head, the bearing diagonal of left end on the sliding block of left end
Grating scale is installed on platform；The left end of speed reducer is equipped with electric cabinet, and display screen, real-time display grating are equipped on electric cabinet
Gauge head reading；The bearing diagonal platform and speed reducer support platform of left and right ends are all fixed on the table.
Compared with background technology, the beneficial effects of the utility model are：The utility model is using hand wheel rotating leading screw come band
Movable slider moves left and right, grating scale fast recording reading, and measurement is accurate, convenient.

Flat key is attached with leading screw 3, and sliding block 4 is attached with leading screw 3 by screw thread；Sliding block 4 is by connecting firmware 6 and grating gauge head
5 are attached, and grating gauge head 5 coordinates grating scale 7 to use, while mandril 10 is equipped on sliding block 4, and mandril 10 is kept with worm screw 11
Concentric state；An axle sleeve 9 is fixed on mandril 10, axle sleeve 9 is fixed on bearing diagonal platform 22, and support is played to mandril 10 and is made
With.The right end of speed reducer 12, leading screw 17 are fixed by leading screw fixing piece 15,18, and leading screw fixing piece 15,18 is fixed on oblique branch
It supports on platform 20, handwheel 19 is attached using flat key with leading screw 17, and sliding block 16 and leading screw 17 are attached by screw thread；It is sliding
Mandril 13 is installed, mandril 13 keeps concentric state with worm screw 11 on block 16；An axle sleeve 14, axle sleeve are fixed on mandril 13
14 are fixed on bearing diagonal platform 20, play a supportive role to mandril 13.The left side of speed reducer 12 is equipped with electric cabinet 25, automatically controlled
Display screen 24 is installed on case 25；The support platform 21 of bearing diagonal platform 20,22 and speed reducer 12 is all fixed on workbench 23
On.
The concrete operations mode of device rotates 12 right end handwheel 19 of speed reducer and left end as shown in Fig. 2 operational flowcharts
Handwheel 1 makes mandril 11 and 13 contact the both ends of worm screw respectively, and the power of right end mandril is first made to be more than the power of left end mandril, makes
Worm screw is moved to left end zero clearance position, is read from display screen 24 and records the scale of grating scale at this time, is denoted as reading 1.Turn
12 right end handwheel 19 of dynamic speed reducer, makes mandril 13 depart from worm screw 11, and then rotates 12 left end handwheel 1 of speed reducer, makes mandril 11
The left side for continuing to head on worm screw 11 is moved, and worm screw is made to be moved to right side zero clearance position, reads and records from display screen 24
The scale of grating scale at this time is denoted as reading 2.The absolute value differences of reading 1 and reading 2, the i.e. axis of worm-gear speed reducer therefore
To displacement.
