Problems solved by technology

[0004] However, when the size of the workpiece is large, the size of the processing table used needs to match the size of the workpiece. At the same time, the number of locking modules required for the zero point positioning system needs to increase accordingly. A locking module is difficult, and the efficiency of clamping and positioning is low

Embodiment 1

[0049] refer to figure 1 and figure 2 , a positioning system for a machine tool station includes a mobile platform 1 and at least two positioning thrust assemblies 2. In this embodiment, there are four positioning thrust assemblies 2. In other embodiments, the positioning thrust assemblies 2 can also be set as other quantities. The positioning thrust assembly 2 is used to be installed on the processing workbench 3 of various processing equipment. The top surface of the processing workbench 3 is equipped with positioning stoppers 4 on both sides adjacent to each other. Correspondingly, two positioning thrust assemblies The pushing direction of 2 is vertical to one side of the processing table 3 , and the pushing directions of the other two positioning pushing assemblies 2 are vertical to the other adjacent side of the processing table 3 .

[0050] The operator clamps the workpiece on the top surface of the mobile table 1, then places the mobile table 1 on the top surface of ...

Embodiment 2

[0063] refer to Figure 4 and Figure 5 , The difference between this embodiment and Embodiment 1 is that when the size of the workpiece to be processed becomes larger, the sizes of the corresponding mobile table 1 and processing table 3 become larger. In this embodiment, there are six positioning thrust assemblies 2 , among which three positioning thrust assemblies 2 have the same thrust direction, and the other three positioning thrust assemblies 2 have the same thrust direction. The number of positioning stoppers 4 on one side of the long side adjacent to the two sides of the top surface of the processing workbench 3 is increased to three.

[0064] Similarly, three positioning and pushing assemblies 2 with the same pushing direction are distributed sequentially along the long side of the top surface of the processing table 3 , and two adjacent positioning and pushing assemblies 2 form a staggered distribution along the short side of the top surface of the processing table ...

Abstract

The invention relates to the technical field of station positioning, in particular to a machine tool station positioning system and a station fixing method.The machine tool station positioning system comprises a movable table and at least two positioning abutting-pushing assemblies installed on a machining workbench, and the abutting-pushing directions of the at least two positioning abutting-pushing assemblies intersect; a positioning blocking piece is arranged on the machining workbench in the abutting-pushing direction opposite to the positioning abutting-pushing assembly, and the positioning abutting-pushing assembly abuts against the moving table to abut against the positioning blocking piece and limits the moving table to be separated from the machining workbench. The machining method further comprises the following steps that firstly, a workpiece is installed on a moving table, and then the moving table is moved to a machining workbench; and 2, synchronously driving the positioning pushing assemblies with the same pushing direction to push the moving table, so that the moving table abuts against each positioning stop piece, and the positioning pushing assemblies are kept to abut against the moving table. The positioning and locking device has the beneficial effects that workpieces can be conveniently and synchronously positioned and locked on different machining stations, the same machining zero point is kept, and the workpiece transposition efficiency and the clamping and positioning efficiency are improved.

Description

technical field [0001] The present application relates to the technical field of station positioning, in particular to a machine tool station positioning system and a station fixing method. Background technique [0002] In the process of processing workpieces, the workpieces often do not stay still. It needs to go from one process to another, from one machine tool to another machine tool, etc. Every time the workpiece is transposed, the zero point of the workpiece needs to be re-detected and corrected. After setting the zero point of the workpiece, it becomes very convenient to process the workpiece, and there is no need to find a relative datum for each dimension. [0003] In related technologies, in order to save the auxiliary time for re-calibrating the zero point, ensure the continuity of workpiece processing, and improve work efficiency, the same zero point positioning system is often used at different stations. The zero point positioning system includes several lockin...
