Embodiment Construction

[0008] like figure 1 As shown, the present invention is a high-precision positioning device under the rapid operation of the CNC lathe tool table, including the tool table 1 arranged on the CNC lathe 6, and the front end of the tool table 1 is provided with an adjustable length contact rod 2. The left front side of the touch rod 2 is provided with a position-adjustable mechanical flow regulating valve for adjusting the hydraulic drive oil circuit of the tool table 1. 3. The right front side is provided with an adjustable limit switch 4. The lower right side is provided with Position-adjustable limit block 5; when the tool on the tool table 1 is close to the material to be processed, the contact rod 2 is in contact with the mechanical flow regulating valve 3. This position has been adjusted during adjustment, and the tool table 1 The hydraulic drive oil circuit is closed by the mechanical flow regulating valve 3, the speed of the tool table 1 is slowed down, and the forward imp...

Abstract

The invention discloses a high-accuracy positioning device of a cutter working platform of a numerical control lathe under fast operation. The front end part of the cutter working platform is provided with a contact rod with adjustable length; the left front side of the contact rod is provided with a mechanical type flow adjusting valve which is used for adjusting a hydraulic driving oil path of the cutter working platform and is adjustable in position, the right front side of the contact rod is provided with a limit switch with an adjustable position, and the right lower part of the contact rod is provided with a limiting block with an adjustable position; when a cutter is close to a material to be processed, the contact rod is contacted with the mechanical type flow adjusting valve, the hydraulic driving oil path is turned down by the mechanical type flow adjusting valve and the speed of the cutter working platform is slowed down; and when the stroke of the cutter working platform reaches a set value, the cutter working platform is contacted with the limiting block, the contact rod is contacted with the limit switch simultaneously, and the cutter working platform returns after finishing the forward action. According to the high-accuracy positioning device, the problem of poor positioning when the numerical control lathe is in fast processing can be solved, and the high-accuracy positioning of the numerical control lathe under fast operation is realized.

Description

technical field [0001] The invention relates to a running positioning device for a tool table of a numerically controlled lathe, in particular to a high-precision positioning device for a tool table of a numerically controlled lathe running rapidly. Background technique [0002] In order to improve the processing efficiency of the CNC lathe, its tool table needs to move forward quickly to save processing time. However, the rapid advance also has a drawback: the tool table can hit the stop, resulting in poor positioning. Contents of the invention [0003] The purpose of the present invention is to provide a high-precision positioning device under the fast running of the CNC lathe tool table, which can solve the problem of poor positioning during the fast machining of the CNC lathe, and realize high-precision positioning under the fast running of the CNC lathe. [0004] To achieve the above object, the present invention can take the following technical solutions: [0005] ...
