Types of Tilting Rotary Tables
Types of Tilting Rotary Tables
A tilting rotary table is a mechanism that is widely used in mechanical drafting and design. Usually a tilting rotary table may be tilted through to being flat all the way to being vertical through the use of hydraulic actuators. A similar type of mechanism is used to drive both the horizontal and vertical movements of the tilting table. There is a motor that moves the hinge on the top of the tilting table and this moves the blade along the slot in the lid of the tilting table. In order for the lid to tilt, a hydraulic arm is used to move up or down and it is often accompanied by a pinion or rack arm that also tilts the table either clockwise or counter clockwise.
There are two main types of tilting rotary tables; self tilt and motorized. Self Tilting Rotary Tables (also called self-tilt tables) are basically just what they sound like. They are hydraulic filters that are hydraulically powered and operate through the use of a pinion or rack arm. The mechanical drafting design concept that is used here is very similar to the mechanism that is commonly used in drafting tables. These are generally most preferred when dealing with flat surfaces such as metals and ceramics as well as non-flammable materials.
A tilting dividing head may also be used in a self-tilt table. However, the tilt of the head does not work with any moving shaft or motor. This type of tilting table has one or two different heads, depending on how many levels to be marked on the material being marked.
The last type of tilting table is a vertical stand alone milling machine. It is designed to move horizontally with the use of a vertical mast or rack on which the workpiece is mounted. The tiller is then manually operated to allow the tiller to move along the surface being marked. The tiller also rotates the vertical shaft that allows the marking process to work. This type of table has its own advantages including accuracy, speed, and ease-of-use.
There are certain specific requirements for using a tilting rotary table, primarily accuracy within the working range of the machine. As such, the horizontal movement of most milling machine should not cross over the level of the table or workpiece. Additionally, the distance from the center of rotation to the edges of any workpiece should not be greater than or less than the distance between the centers of the divided plates on the table. Additionally, the distance between the center of rotation and the workpiece should never be greater than or less than the distance between the centers of the marking heads on the vertically positioned marking plates. Finally, if the work to be measured is sensitive, it may be necessary to mark along edges rather than along the center of rotation.
When purchasing tilting rotary tables, there are several factors to consider which include their suitability for the application in question. It is important to know the torque specifications as these are critical for calculating the force used to lift a workpiece to a specified height and for determining the level of accuracy desired. Furthermore, the tilt adjustment should be considered since this will affect the accuracy of lifting. In general, vertical tilting tables are preferred in situations where the tester does not need to lift the piece vertically but needs to manipulate the device horizontally. On the other hand, horizontal tilting tables are appropriate for lifting very heavy loads. In either situation, the appropriate type of table will be chosen to ensure that all measurements are exact and that the manufacturer receives all of his or her funds.
