Technical Field

The invention relates to the technical field of cross sliding tables, in particular to a ball screw cross sliding table.

Background

The cross sliding table is a combined sliding table formed by combining two groups of linear sliding tables according to the X-axis direction and the Y-axis direction, is generally called as a coordinate axis sliding table and an XY-axis sliding table, and is usually used for indicating the X-axis in a transverse direction in industry, and the other axial direction is the Y-axis. When the middle point of the X axis is coincident with the Y axis, the appearance looks like a cross in the text, and the name of the cross sliding table comes from the cross sliding table, and the working principle of the cross sliding table is as follows: and the sliding block is fixed on the sliding block of the other group of sliding table through one group of linear sliding table. For example: the X shaft is fixed on the sliding table of the Y shaft by the cross sliding table, so that the sliding block on the X shaft is a moving object, the Y-direction movement of the sliding block can be controlled by the Y shaft, the X-direction movement of the sliding block can be controlled by the X shaft, and the movement mode is generally realized by external drive. Therefore, the sliding block can complete fixed point motion, linear motion or curvilinear motion on a plane coordinate.

The ball screw is composed of a screw, a nut, and balls, and is the most commonly used transmission element in machine tools and precision machines. The function of the device is to convert the rotary motion into the linear motion, which is the further extension and development of the ball screw, the important significance of the development is to change the bearing from the rolling motion into the sliding motion or convert the torque into the axial repeated acting force, and the device has the characteristics of high precision, reversibility and high efficiency. Due to the small frictional resistance, the ball screw is widely applied to various industrial equipment and precision instruments, and can realize high-precision linear motion under the condition of high load.

The general level of current cross slip table is fixed or is vertically fixed and use on the plane, when needs slope is placed, need prepare specific fixed plane, it is convenient inadequately to use, simultaneously at the in-process that the slider removed along the lead screw, can be because the friction produces the heat between lead screw and the slider, lead to the temperature rising of lead screw and slider, influence the life of lead screw and slider, in addition, interval between two sharp slip tables of cross slip table is fixed, can not adjust, work piece when fixed extends for a long time downwards on the sharp slip table at top, the work piece removes the in-process and is disturbed by the sharp slip table of bottom easily, influence the removal of work piece, for this we provide ball screw cross slip table.
