The utility model discloses simple structure, simple to operate, the precision is high, can bear the 100t heavy load, can satisfy wind tunnel test section and turn to 90 needs.
Description
Technical field
This utility model is related to the rotating-table apparatus of test chamber, belongs to the assay device field in wind tunnel test, mainly
It is that rolling element is used as by steel ball, rotational freedom is defined to by adjusting rod, power source is used as by hydraulic cylinder, realizes rotating disk
The test section at top is safe and reliable to rotate 90 °.
Background technology
Test chamber is the core apparatus of wind tunnel test, and almost all of wind tunnel test is all completed in test section.Wind
Hole first stage of construction, most of wind-tunnel only supporting 1 or 2 test sections are by test section straight line moving in orbit
The replacing of achievable test section.Along with the development of wind-tunnel technique, must set up various types of many in a wind-tunnel
Individual test section is meeting different test demands.And after test section increasing number, test is changed in the Factory Building of the confined space
Section can not possibly realize that arranging rotating disk makes test section direction of travel turn 90 °, so as to by test section only by the mode of straight line moving
The designated area walked to Factory Building becomes necessity.
Test chamber rotating disk in the past is that (2 drivewheels, 2 driven pulleys, drivewheel is by motor and subtracts by 4 wheels
Fast machine drives) rotate what is realized on round circular orbit.Only 4 wheels and rail contact are primarily due to, the strong point is very few,
When test section is gone on or walks lower rotary table, a wheel of rotating disk can be tilted by pressure.Secondly because the interior outside of wheel rotates
Linear velocity is inconsistent, causes track that sliding friction occurs with wheel, and long-term work causes drivewheel and path wear serious, actively
Wheel vacantly runs out of steam, and loses the function that rotating disk turns 90 °, and driven foot wheel abrasion is weaker, causes the diameter of 4 wheels inconsistent, and 4
Individual wheel is wave walking on round circular orbit.The last connection due to drivewheel and motor and reductor is rigid company
Connect, in rotating disk start and stop and wave walking process, the load of motor and reductor changes very greatly, easily damages.
The rotating-table apparatus of test chamber involved by this utility model are simpler than original mechanism, reasonable, with bearing capacity
By force, the features such as rolling resistance is little, rolling element is hardly damaged, driving means are reliable, due to not affecting the ground of original rotating disk and adding
Adjusting rod, therefore easy installation and removal are filled, disk cover accurate positioning is the rotating disk of the very strong test chamber of a set of practicality
Device.
The content of the invention
This utility model provides a kind of rotating-table apparatus of test chamber, and carousel supports points is very few before solving, rolling
Kinetoplast serious wear, the driving means load excessive deficiency of change, with simple and reasonable, mechanism's bearing capacity is strong, roll
The characteristics of resistance is little, rolling element is hardly damaged, driving means are reliable, due to not affecting the ground of original rotating disk and having installed regulation additional
Bar, therefore disk cover accurate positioning, easy installation and removal, with very strong practicality.
The rotating-table apparatus of test chamber of the present utility model, it is characterised in that：Including disk cover, disk seat, base, steel ball,
Adjusting rod and hydraulic cylinder；Base is fixed on ground as supporting construction, and disk seat is arranged on base and maintains static, disk seat and disk
By the push-and-pull of hydraulic cylinder, the rotation of 90 ° of disk cover is realized, so as to drive disk cover top as rolling element using 5 row's steel balls between lid
The test section in portion realizes 90 ° of steerings.
It is preferred that also including adjusting rod, the position of adjusting rod adjustment plate seat can be passed through, so that standard of the disk seat on base
It is determined that position.
It is preferred that by adjusting rod and the positioning of 5 row's steel balls, define that only there is the degree of freedom for rotating between disk cover and disk seat,
Without the degree of freedom in other directions.
It is preferred that the auto-lock function that hydraulic cylinder has enables the turned position of disk cover to fix.
The utility model has the advantages that：
1st, a kind of rotating-table apparatus of test chamber of this utility model, using 5 row's steel balls as rolling element, it is to avoid due to
The very few rotating disk for causing of the strong point has been pressed the phenomenon of nose by heavy load, with the strong point it is intensive, support force is evenly distributed, carry
The strong advantage of ability.
2nd, a kind of rotating-table apparatus of test chamber of this utility model, using 5 row's steel balls as rolling element, it is to avoid due to
The inconsistent sliding friction for causing of out conductor speed in wheel, with rolling resistance is little, the non-damageable advantage of rolling element.
3rd, a kind of rotating-table apparatus of test chamber of this utility model, using hydraulic cylinder as driving means, can bear
The load large change that heavy load acceleration and deceleration are caused is driven, has the advantages that driving means are simple and reliable.
4th, a kind of rotating-table apparatus of test chamber of this utility model, due to not affecting the ground of original rotating disk, and install additional
Adjusting rod, therefore disk cover accurate positioning, easy installation and removal, with very strong practicality.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is schematic view of the mounting position of the present utility model.
Specific embodiment
As shown in figure 1, this utility model provides a kind of rotating-table apparatus of test chamber, its feature includes disk cover 1, disk
Seat 2, base 3, steel ball 4, adjusting rod 5, hydraulic cylinder 6.
Base 3 is fixed on ground as supporting construction, and disk seat 2 is installed and maintained static on the base 3, between disk cover 1
Using 5 row's steel balls 4 as rolling element, by the push-and-pull of hydraulic cylinder 6, the rotation of 190 ° of disk cover is realized, so as to drive the top of disk cover 1
Test section realize 90 ° steering.
By the position of the adjustment plate seat 2 of adjusting rod 5, being accurately positioned on the base 3 of disk seat 2 is realized.
By the positioning of the row's steel ball 4 of adjusting rod 5 and 5, define that only there is the degree of freedom for rotating between disk cover 1 and disk seat 2,
Without the degree of freedom in other directions.
Using 5 row's steel balls 4 as rolling element between disk seat 2 and disk cover 1, so as to realize that disk cover 1 is bearing the feelings of heavy load
Can rotate between disk seat 2 under condition.
The rotation of 190 ° of disk cover realized by the push-and-pull of hydraulic cylinder 6, the auto-lock function that hydraulic cylinder 6 has is so that disk cover 1
Turned position can be fixed.
